Subject: [PATCH 0003/1987] Update ServerObserver with received request and
 sent reply counts

Summary:
- When the ThriftServer receives a request and when it sends a reply back, it needs to update the TServerObserver object with this information.
- RSocketServer should inform the number of connections actively connected to the server.
- Fix the unit test related to ConnectionStats when RSocket is used.

Subject: [PATCH 0006/1987] cleaning up setting protocol version

Summary:
rsocket client calling connect() method was never setting up protocol version. rsocket server was setting up protocol version so I made an explicit method which is called in the server case
The new guards around transport are going to be removed once I eracidate FrameTransport. (ideally FrameTransport would be held by unique_ptr and automaticaly closed in the dtor. Currently there is a circular reference so we have to eplicitly call close())

(Note: this ignores all push blocking failures!)

Subject: [PATCH 0008/1987] Codemod yarpl::Reference -> std::shared_ptr

Summary:
Step 1 in removing the yarpl::Reference alias, to simplify the
yarpl API. At the moment, users need to know that yarpl::Reference
is an alias to std::shared_ptr, causing some confusing.

Subject: [PATCH 0010/1987] Add Flowable::never() that never sends anything to
 the subscriber

Summary:
This is useful for eg a channel where you never want to send a
response.

Subject: [PATCH 0011/1987] Make ~ConnectionSet synchronous

Summary:
It's asynchronous right now, and this ends up making server shutdown a lot
harder, as we can't reason about what the state of connections and subscribers
are after ~RSocketServer.

Changes the std::weak_ptr<ConnectionSet> field in RSocketStateMachine to a
ConnectionSet*.  We make a hard requirement that if an RSocketStateMachine is
registered to a set, then the set must outlive it.  Also saves 8 bytes per
RSocketStateMachine which is nice.

This only affects RSocketServer shutdown, so there shouldn't be any visible
change in perf except for servers with extremely tiny lifetimes.  Each
individual connection is still closed off in parallel, only the thread running
~ConnectionSet will block.

Subject: [PATCH 0014/1987] rsocket: avoid link issues with gcc7 and gold

Summary:
Remove the constexpr from the definition of the static ProtocolVersion::Unknown member
to ensure it's made available to the linker.

Subject: [PATCH 0015/1987] simplify Flowable emitter

Summary:
In this change I removed the need to track the number of onNext calls on terminating signals for each emitter. It was a bug prone design.
Emitters are always synchronous (because of the design of EmitterOperator) so there is no concern about concurrency.

Subject: [PATCH 0016/1987] renaming Observables to Observable<>

Summary:
Stealing ideas from other libraries. Its simpler to use only one templated class Observable<..> then Observables and Observable<T>.

Depends on D6756992.

Subject: [PATCH 0021/1987] removing template param from FlowableOperator

Summary:
FlowableOperator was storing a pointer to the parent Flowable which was used only in less than 50% of the cases. By removing the pointer there is no need to pass in the 3rd template argument.
This change also reduces denerated symbols as Flowable<U, D> is more generic than Flowable<U, D, T>.

Depends on D6822101.

Subject: [PATCH 0026/1987] fixing exception object slicing in
 Flowable(Observable)<T>::error(..)

Summary:
This was potentially a nasty bug where we would move from the object reference (!!)  and slice the exception object in the ctor of the folly::exception_wrapper

Depends on D6821225.

Subject: [PATCH 0029/1987] removing template param from ObservableOperator

Summary:
ObservableOperator was storing a pointer to the parent Observable which was used only in less than 50% of the cases. By removing the pointer there is no need to pass in the 3rd template argument.
This change also reduces denerated symbols as Observable<U, D> is more generic than Observable<U, D, T>.

Depends on D6821738.

Subject: [PATCH 0033/1987] TakeOperator should support requesting no items,
 take(0)

Summary:
take operator is different than ignoreElements operator that
 - ignoreElements waits till all of the elements are consumed from the producer and ignores them
 - take operator only takes as many elements at it is asked for and just unsubscribes from the source

So if take(0) is issued, it will mean take no item from the source and just immediately complete.

With the current implementation flowable.take(0) was causing infinite wait for completion event. This diff fixes that.

Subject: [PATCH 0034/1987] Improvements on NeverOperator related tests

Summary:
Wait a while to make sure that never() operator will never emit anything.

Even if never() operator never emits anything (onNext, onComplete, onError), take(0) does not wait the upstream to provide anything, so it immediately completes without waiting the upstream.

Subject: [PATCH 0035/1987] RSocketStateMachine::onStreamClosed() shouldn't
 call endStream()

Summary:
When a stream's state machine calls onStreamClosed(), it has already closed off
all of its state.  All it needs from the RSocketStateMachine is to remove the
stream object from its StreamState map.

The current behavior is StreamStateMachineBase::closeStream() calls
RSM::onStreamClosed(), which loops back into
StreamStateMachineBase::endStream().  This is wasteful as in all cases we have
already ended the stream.

Rename StreamStateMachineBase::closeStream() to removeFromWriter() to better
describe its behavior.

Subject: [PATCH 0036/1987] ConcatWith operator for yarpl/Flowable

Summary:
Add ConcatWith operator to Yarpl/Flowable.

```
auto combined = first.concatWith(second);
combined.subscribe(subscriberA);
```

1. Create a ConcatWithSubscription instance (which is a Subscription/Subscriber).
Provide subscriberA to this subscription, name it subscriptionA.
Provide subscriptionA to subscriberA.
Call onSubscribe on subscriberA.

2. For each flowable, first and second, create a new Subscriber/Subscription (B)
Make Subscriber_B to forward each onNext, onError to SubscriberA, except onComplete and onSubscribe!
Make Subscription_A to forward each request() calls to Subscription_B

3. When flowable First completes, create a new Subscriber/Subscription (B) and
still forward the calls onNext, onError, onComplete to/from Subscriber_A and Subscription_A, except onSubscribe!

Don't subscribe to the second flowable till the first one is consumed up.

Subject: [PATCH 0040/1987] More refactoring on StreamStateMachineBase

Summary:
Rename the {errorStream, cancelStream, completeStream, applicationError} methods
to {writeInvalidError, writeCancel, writeComplete, writeApplicationError}.
Making it clear that all these functions do is write a frame over the
connection.  Update writeInvalidError() to not end the stream, fixup the few
callsites manually.

Subject: [PATCH 0041/1987] Implement fragmentation for requests

Summary:
WIP implementation of fragmented requests for RSocket. Allows payloads > 16MB to be sent. Should be efficient and not copy large payloads, if IOBuf refcounting is working correctly under the hood. Should not incur much extra overhead if a payload is not fragmented (aside from a cheap check to see if any fragments for the current stream already exist; should be no more expensive than `if(pointer == null)`).

Test implemented:
 - Request/Response

Tests not implemented yet:
 - Request Stream
 - Request Channel

Existing testsuite should pass.
Closes https://github.com/rsocket/rsocket-cpp/pull/856

Subject: [PATCH 0042/1987] Phase out Promise::getFuture in rsocket.

Subject: [PATCH 0044/1987] Implementation of PublishProcessor

Summary:
This is gonna be useful for replacing fromPublisher when we need to defer connecting consumer to flowable.
http://reactivex.io/RxJava/2.x/javadoc/io/reactivex/processors/PublishProcessor.html

new unit tests added.
Closes https://github.com/rsocket/rsocket-cpp/pull/859

Subject: [PATCH 0046/1987] Delete StreamStateMachineBase::isTerminated_

Summary:
All subclasses of SSMB already have their own State fields for tracking where
they are in their lifetime.  Make sure we set this state to State::CLOSED in all
cases where we were previously calling StreamStateMachine::endStream().

Subject: [PATCH 0047/1987] Merge StreamState into RSocketStateMachine

Summary:
StreamState as an abstraction is an awkward mess.  It holds the map of stream
IDs to stream state machines, but it never uses it.  All it does is expose it as
a public field.  It also holds the queue of pending frames to be output, which
makes for an awkward combination with the stream machine map.

Move the two fields over to RSocketStateMachine instead.  I'm intentially moving
the `StreamId -> StreamStateElem` map right next to the `StreamId ->
StreamFragmentAccumulator` map because I think they should be merged in the
future.

Summary:
1) Replaced 2 uses of C array with std::array in fbcode/rsocket/ in order to to suppress HOWTOEVENLINT warnings.
2) replaced memset(0) by equivalent (but safe) C++11 style initialization `= {}`.

Subject: [PATCH 0052/1987] fbcodeify directory structure of yarpl

Summary:
> Projects that use autodeps (such as smc) have trouble with
including yarpl as a dependency due to the yarpl header map.
This makes the directory structure closer to that of a standard
fbcode project.

> update liger autosyncer to include yarpl test utils

> manual autosync of yarpl xplat

Subject: [PATCH 0054/1987] Fix opensource cmakelists

Summary:
- the yarpl has been reorganized, update the cmakelists file to match
 - rsocket was made more const-correct, which broke some stuff in the tck driver
 - opensource toolchains make some different assumptions about implicitly included standard headers
Closes https://github.com/rsocket/rsocket-cpp/pull/862

Subject: [PATCH 0055/1987] SubscribeOnOperator should subscribe on the
 executor thread

Summary:
Should SubscribeOnOperator subscribe on the executor thread, so that
the onSubscribe() callback is also executed on the executor?

It seems like this is the case for observable
(diffusion/FBS/browse/master/fbcode/yarpl/include/yarpl/observable/ObservableOperator.h$441-446)
but not for flowable.

Subject: [PATCH 0056/1987] Pass folly::StringPiece to Payload ctor instead of
 const std::string&

Summary:
We're copying the string into a folly::IOBuf with folly::IOBuf::copyBuffer().
It's better to take folly::StringPiece so that places where we have a string
literal aren't forced to allocate a std::string object.

Only affects ERROR frames so I'm not expecting any perf improvements, but I
think this is still good to do.

Subject: [PATCH 0062/1987] Add type-erasing move-only value-type wrappers for
 flowable types

Summary:
Ports over the type-erasing wrappers found in experimental/dymk/strm

Introduces `AnySubscriber<T>`, `AnySubscription`, `AnyFlowable<T>`, and value-type wrappers which understand how to wrap shared-pointer objects which respond to Subscription/Subscriber methods (or a Compound, which is a combination of both subscription/subscriber).

Subject: [PATCH 0063/1987] - Fix unused parameter warning in
 BaselinesAsyncSocket.cpp

Summary: We are going to enable `-Werror=unused-parameter` flag and I need to manually fix some files so we rest of this process can be automated with a tool called clang-tidy.

Summary:
The unit tests explain the situation. But just like FlowableFromPublisher releases downstream subscriber the ObservablePublisher needs to release downstream observer when terminated with on{Complete,Error}.

Depends on D7056795.

Subject: [PATCH 0072/1987] Fix RSocketResponder's EagerSubscriberBridge
 crashing on early onComplete()

Summary:
EagerSubscriberBridge is a Subscriber that lazily wraps another subscriber.  It
can register its inner subscriber _after_ the wrapping onSubscribe() and also
on{Complete,Error}() are called.

The code in onComplete() was asserting that we already had an inner subscriber
registered, which is not necessarily true and the code already handles that case
after the bogus assertion.

Was triggering in GW code when using channels with invalid methods.

Subject: [PATCH 0075/1987] Exposing BackpressureStrategyBase.

Summary:
Exposing existing internal base class for backpressure strategy in public API so that applicaiton code implementing custom backpressure strategy can simply extend it.
This is used in my following diff.

Depends on D7091083.

(Note: this ignores all push blocking failures!)

Subject: [PATCH 0076/1987] - Fix unused parameter warning in
 BaselinesAsyncSocket.cpp

Summary: We are going to enable `-Werror=unused-parameter` flag and I need to manually fix some files so we rest of this process can be automated with a tool called clang-tidy.

Subject: [PATCH 0077/1987] Concat operator should release ownership of the
 Subscriber

Summary:
In this newly added unit test, even if we cancel the `subscriber` at the end, the subscriber object wasn't get destroyed.

With this update, I delete all cyclic links when either subscription completes or get cancelled. So, the external `subscriber` gets released.

We will use `concat` operator in Thrift.

Subject: [PATCH 0078/1987] Don't keep a shared_ptr to RSocketStateMachine in
 StreamStateMachineBase

Summary:
This cycle isn't necessary.  In almost all cases, the RSocketStateMachine (as a
StreamsWriter) outlives the StreamStateMachineBase.  This means we should be
able to keep a raw back-reference (StreamsWriter&) instead of a full shared_ptr.

There's a few issues with removeFromWriter() being called more than once, and
when the StreamsWriter& back reference is no longer pointing to valid memory.
We can dodge that by setting the stream's ID to 0.  Add a bunch of debug checks
to ensure we're not trying to write stream frames with ID 0.

Shrinks StreamResponder from 72 bytes down to 64 bytes.

Subject: [PATCH 0081/1987] RSocket build fix

Summary:
Google's Mock library behaves differently in internal builds versus external builds, which caused build breaks.

Google Mock doesn't accept RValue inputs in external build.
Closes https://github.com/rsocket/rsocket-cpp/pull/863

Subject: [PATCH 0085/1987] Merging Observer<T> and Observers classes

Subject: [PATCH 0088/1987] Subscribing multiple times to the resultant Stream
 objects of

Summary:
We needed to clone the initial `request`, so each subscribe call to the result can use use it.

Without cloning the `request`, the first subscribe causes the remote call with correct data, but it also destroys the `request` object. So subscribing again causes crash instead of sending a new request.

We need this functionality for `retry` operation in Yarpl.

Subject: [PATCH 0089/1987] Adding unit tests for multiple subscription of
 RequestChannel/RequestStream

Summary: Other than adding these unit tests, I have updated the Flowable::range and Flowable::justN method to support subscribing multiple times. They don't support having concurrent subscriptions still though.

Subject: [PATCH 0091/1987] Specialized TakeFirst operator on Flowable for
 Thrift

Summary:
This specialized TakeFirst operator returns a SemiFuture which is fulfilled
when the first value is consumed from the upStream.
So it converts Flowable<T> into std::pair<T, Flowable<T>>

TakeFirst operator results into a single subscribe only Flowable.
If the result is subscribed again, subscriber will get an error immediately.

Subject: [PATCH 0093/1987] Make TcpConnectionAcceptor::stop() synchronous
 again

Summary:
I could have sworn it was synchronous already...

Doing this shutdown asynchronously can cause issues with RSocketServer, as we
expect to be able to shutdown the ConnectionAcceptor and not racily get any new
connections coming in after `stop()` has been called.

Subject: [PATCH 0094/1987] Back out "Don't keep a shared_ptr to
 RSocketStateMachine in StreamStateMachineBase"

Summary:
I'm seeing crashes where stream state machines are accessing the connection
state machine after their stream IDs have been set to zero, and just an increase
of crashes in general.  I think this diff is the culprit.

The diff in question was just a small optimization, so it's fine to back it out.

Subject: [PATCH 0097/1987] Concat operator should buffer 'cancel' state as
 like it does for 'requestN'

Summary:
We specifically observe the issue if we have a subscribeOn(executor) on the second flowable.

As it delays the onSubscribe(subscription) call, if the consumer early calls the 'cancel' method, it was not able to find the 'subsciption' to cancel.

So as we remember the 'requestN' call and forward the remaining to the second flowable, we now remember the 'cancel' call and also forward it to the second flowable.

Subject: [PATCH 0099/1987] Timeout operator for Flowables

Summary:
Added timeout() operator to Flowable class.

Because of these reasons,
- We don't have Schedulers in Yarpl.
- All the possible users of this operator already have explicit event bases.

timeout operator requires an explicit Eventbase input in this version.

Subject: [PATCH 0100/1987] Gracefully handle the already accepted but not
 registered connections while closing the RSocketServer

Summary:
When the RSocketServer shuts down, it first closes the connection acceptor, which is a DuplexConnectionAcceptor.
It then closes the `setup frame` acceptors, which are the instances of SetupResumeAcceptor.

If a connection is already accepted via DuplexConnectionAcceptor but not yet accepted by SetupResumeAcceptor, then this connection will start waiting for the Setup Frame. In this case, when the `setup frame` arrives the server, the RSocketServer instance will already be deallocated.

 - Updated the RSocketServer code and made the onRSocketSetup function don't depend on the RSocketServer instance, via making it a static function.
 - As the ConnectionSet implementation is improved to be safe for such races, I have updated RSocketServer to keep shared_ptr to this class instead of unique_ptr and I have provided a weak_ptr of this data member into the onRSocketSetup lambda function. So I have deferred the responsibility to that class.

These two updates enabled the onRSocketSetup function to further be able to understand if the server is shutting down and it doesn't access to the already deallocated objects anymore.

--

Furthermore, RSRoutingHandler's two methods, handleConnection and stopListening, is called by two different threads.
 - This causes race condition between destruction of RSocketServer and calling acceptConnection method on it.
 - As we have made RSocketServer safe on calling shutdownAndWait and acceptConnection, instead of keeping
 - RSocketServer as unique_ptr, we keep it as shared_ptr at the RSRoutingHandler class.
 - So we also defer the graceful handling of races at the destruction to RSocketServer which defers it to ConnectionSet.

Subject: [PATCH 0104/1987] Fix Subscriber not doing requests with batch size
 of 1

Summary:
When using `Subscriber<T>::create` with batch size of 1, the resulting subscriber calls `request(1)` only once in `onSubscribeImpl` and incorrectly skips `request` call in `onNextImpl`.

This patch fixes this issue, as well as a test, which relied on this bug.

Subject: [PATCH 0107/1987] Wipe the StreamsFactory class, eliminates cyclic
 reference with RSocketStateMachine

Summary:
RSocketStateMachine keeps StreamsFactory as a shared_ptr internally. StreamsFactory also keeps a reference to the RSocketStateMachine from which it calls shared_from_this() and provides to other StreamStateMachines.

We did not need this cyclic reference, so this update gets rid of StreamsFactory class.
I also added unit tests for requestStream and responseStream related functions in RSocketStateMachine.

Subject: [PATCH 0108/1987] Convert fireAndForget method to accept Subscriber
 instead of returning Flowable

Summary: This update eliminates unnecessary creation of a Flowable from a Subscriber and then immediately subscribing to it for the fireAndForget function.

Subject: [PATCH 0109/1987] Yarpl: Eliminate leaks on terminal

Summary:
As Subscriber/Subscription is tied to each other with shared_ptr's, its very crucial to reset all the shared_ptr's at the terminal state.

I have observed that most of the operators miss .reset() of the internal reference from a Subscription to the corresponding Flowable, which results memory leaks.

This update eliminates them.

Subject: [PATCH 0110/1987] Throw instead of crash on stream ID overflow

Summary:
We shouldn't be crashing if we happen to overflow on stream IDs.  However we
should crash if we create a new stream ID and it somehow already exists in the
map.

Context - I'm seeing a lot of crashes around creating StreamRequesters and
adding them to the streams map.  It _seems_ like somewhere we're failing to
insert the StreamRequester into the map, and the only way that can happen is if
we have a duplicate ID somewhere...  Hopefully this might give us more
meaningful crashes on mobile.  Otherwise it shouldn't do anything new.

Subject: [PATCH 0111/1987] Delete ProtocolVersion::Current()

Summary:
We had this method to be able to set a default version from the command line.
In reality, we don't want to default to anything, we want to run whatever
version the client tells us to run, and that's either 0.1 or 1.0.

Start with getting rid of this Current() static method, and replacing all uses
of it with ProtocolVersion::Latest, which is what it is in all cases already.

Subject: [PATCH 0113/1987] Make RSocketStateMachine don't depend on
 ConnectionSet

Summary:
If we add a generic CloseCallback to RSocketStateMachine and use this callback to inform that the state machine is closed, then we can get rid of the ConnectionSet pointer in the RSocketStateMachine.

Why? I want to use wangle::ConnectionManager to manage the connections as it's already used as the connection manager in Thrift. This hard dependency to ConnectionSet wasn't allowing replacement of the connection manager.

Subject: [PATCH 0117/1987] Fix build failure of rsocket/examples

Summary:
One of the recent changes made the rsocket/examples build fail.
The reason is missing include of `sstream`.

Also applied clang-format on the example files that I have touched.

Subject: [PATCH 0118/1987] Split ProtocolVersion into its own module in
 rsocket/framing

Summary:
This belongs in with the rest of the framing code.  Right now it's split between
the mess that is rsocket/internal/Common.h but also
rsocket/framing/FrameSerializer.cpp for some reason.

Getting us closer to having rsocket/framing be its own library, separate from
the rest of the rsocket/ code.

Subject: [PATCH 0119/1987] Make core RSocketResponder class operate on
 Subscribers

Summary:
RSocketStateMachine uses only the core functions of RSocketResponder class, ie. requestResponseCore, requestStreamCore etc.. So this update makes it accept an instance of RSocketResponderCore, which only provides these functions.

The difference between the core and extension functions is that, core functions only depend on Subscriber while the extension functions convert the Subscribers into Flowables. Flowables are heavier than Subscribers as they provide multi-subscribe/retry etc functionalities which are not to be used by Thrift.

This update will provide opportunity for advanced uses of RSocketStateMachine with RSocketResponderCore implementations, which will eliminate extra redirection and memory usage.

Subject: [PATCH 0120/1987] Provide ManagedRSocketConnection class to enable
 using wangle::ConnectionManager for RSocket

Summary:
RSocketServer is a stand alone server which has its own Acceptor and Connection Manager.
Thrift already uses Wangle to accept client connections and also to handle connections.

So there is no need to use the Acceptor and Connection Manager functionalities of RSocketServer.

In this diff,
 - Added a new class, ManagedRSocketConnection, which represents a RSocket client connection (RSocketStateMachine) that is encapsulated by ManagedConnection.
 - RSRoutingHandler is updated to use ManagedRSocketConnection class instead of RSocketServer.
 - The instance of ManagedRSocketConnection is managed by the wangle::ConnectionManager.

This greatly reduces amount of dependency from thrift/transport/rsocket/server to RSocket project.

Subject: [PATCH 0121/1987] Use Empty ResumptionManager to eliminate
 unnecessary caching

Summary:
When the resumption capability is added to RSocket, its assumed that it will be used extensively. But it's not the case.

If nullptr is provided instead of WarmResumptionManager parameter to the RSocketStateMachine, it internally creates an instance and tracks the frames, instead of assuming that the user doesn't want any resumption.

With this update, we provide an Empty version of WarmResumptionManager to RSocketStateMachine, so it will not create an internal/default version.

The Empty version doesn't cache any frame. So it should bring both memory and cpu usage benefits.

Subject: [PATCH 0123/1987] Update RSResponder to inherit from
 RSocketResponderCore and use Subscriber instead of Flowable

Summary:
RSResponder, which was inheriting from RSocketResponder, was providing functions which return a Flowable or Single.

Flowable/Single works in lazy fashion. Nothing happens up until they are subscribed to and they also provide multi-subscribe related abilities. All of these abilities were not used in Thrift. The Flowable/Single was immediately subscribed to and it was only subscribed once. For such scenario, there is no need to convert a Subscriber/SingleObserver to these objects.

With this update, we throw away this indirection, which both saves from memory usage and also reduces function call redirections.

Subject: [PATCH 0125/1987] - TimeoutOperator improvements

Summary:
- Require user provided initialTimeout parameter
- Support custom timeout exception type - when times out, it throws this exception (so it can throw TTransportException::TIMEDOUT instead of a custom Yarpl exception)

Subject: [PATCH 0128/1987] Get FrameFlags out of Payload

Summary:
Mostly a refactor.  Payload is functionally just a pair of IOBuf pointers.  It
shouldn't know about frame flags, how to produce them, or check them.  Payload
is something we expose to users in the top-level RSocket client APIs, whereas
FrameFlags is not.

Move Payload::getFlags() and Payload::checkFlags() over to Frame.{cpp,h}.  At
the same time, make checkFlags() throw when the METADATA flag doesn't match the
existence of the metadata buffer.  We shouldn't be able to construct a Frame of
this form.

Subject: [PATCH 0129/1987] Add a test for a requestStream() call that
 immediately cancels

Summary:
Presumably we should be okay with creating the stream state machine, and then
cleaning it up after it immediately cancels.

Came up with the test when investigating some crashes.  Test passed, and I
figure it's worth committing.

Subject: [PATCH 0130/1987] Eliminate RSocketRequester usage in RSRequester

Summary:
Update TakeFirst class such that it can be used in StateMachine->requestStream(takeFirst) call.
This makes RSRequester to don't need RSocketRequester, so one less dependency.

In the next diff, it will help us get rid of RSRequester too and make RSocketClientChannel to directly use RSocketStateMachine. Another dependency will be gotten rid of.

Subject: [PATCH 0131/1987] Prevent RSocketStateMachine from closing connection
 on receiving unknown frames

Summary:
If a Stream is early closed that the RSocketStateMachine is still receiving frames related to that stream, it was causing RSocketStateMachine to close the connection.

We ignore those frames as the protocol states:
`Receiving a PAYLOAD on an unknown Stream ID (including 0) MUST be ignored.`

These were necessary to make std::unordered_map<K,V>::emplace<Args&&...>() infer
the correct constructor to call for the value type.  A shorter way to do this is
to construct the value type directly, and pass it in as V&&.

Subject: [PATCH 0134/1987] Assorted StreamRequester refactoring

Summary:
Mostly just flipping long `if` statements into shorter ones.  Slightly better
behavior in StreamRequester::request() with implicit conversions between signed
and unsigned.

Only behavior change should be the CHECK() in StreamRequester::handlePayload()
being replaced with handleError().  I did that just because I didn't want to
crash in case a bad server sent us a PAYLOAD frame for a stream that hadn't
requested yet.

Subject: [PATCH 0140/1987] Delete RSocketStateMachine::endStreamInternal()

Summary:
It's only called from closeStreams().  closeStreams() does more than it needs
to, where it finds the first element in the map, and then searches for it again
to remove it.

We can make things simpler by doing all the work in closeStreams(), no searching
the map is needed.

Subject: [PATCH 0143/1987] Fix StreamRequester::{request,cancel}() being
 callable after cancel()

Summary:
Turns out RSocketStateMachineTest.StreamImmediateCancel was doing a bad thing
where it called cancel() and then request() on the StreamRequester subscription
(because of how MockSubscriber works).  This goes against the API of
Subscription, but make StreamRequester tolerate it anyway, in case of bad
clients.

Subject: [PATCH 0144/1987] Minor refactoring on Channel{Requester,Responder}

Summary:
Simple things like getting rid of noexcept, making public overridden methods
public, and matching method ordering across headers and source files.

Merged ChannelResponder::onNextPayloadFrame() into
ChannelResponder::handlePayload() as they were nearly the same method.

Subject: [PATCH 0147/1987] Delete PublisherBase::checkPublisherOnNext()

Summary:
It makes assertions about the private state of PublisherBase, which can just as
well be done inside of the class rather than outside of it.  Either way the
assertion isn't that valuable and can be removed all together.

Bit of StreamResponder cleanup thrown in as well.

Subject: [PATCH 0153/1987] Fix termination behavior of StreamResponder

Summary:
When a StreamResponder is terminated early it must send an ERROR frame to the
requester.  We are currently not doing this.

I don't expect this to fix any bugs we're currently seeing in production, this
just seems like incorrect behavior in general.

Subject: [PATCH 0154/1987] Fixes for ScheduledFrame{Processor,Transport}

Summary:
* Shorten lifetimes of inner FrameTransports/FrameProcessors by moving them out
  on terminal signals.

* Get rid of yarpl::enable_get_ref from ScheduledFrameTransport.  Capturing a
  hard reference to it was not necessary, we can get away with making a copy of
  the inner transport instead.

* Replace folly forward declares with #includes.

* Add copyright headers where I found them missing.

Subject: [PATCH 0156/1987] No longer allow continuations taking non-const
 lvalue-ref

Summary: [Folly] No longer allow continuations taking non-const lvalue-ref, since that is not really necessary - callers can get all the same results using continuations taking non-const rvalue-ref instead.

Subject: [PATCH 0160/1987] Change calls from collectAll to
 collectAllSemiFuture

Summary: We are changing `folly::collectAll` to return `SemiFuture` rather than `Future` and this is needed as an interim step. After all calls to `collectAll` are changed to `collectAllSemiFuture`, we'll be renaming it back to `collectAll`.

Subject: [PATCH 0161/1987] Get rid of global map for frame flags printing

Summary:
ARM has some weird issues with static constructors, tending to crash on them.
Get rid of this std::map and replace it with constexpr constructs.

Subject: [PATCH 0165/1987] Moving fragmentation handling to streams state
 machine

Summary:
Previously the fragmentation handling was spread in RSocketStateMachine frame handling methods. It was very hard to refactor them as they had a lot of
assumptions built in. I moved the logic completely to the streams state machine. As a result the RSocketStateMachine only bypasses payloads directly to the stream state machine which will process it.
This is a necessary change for the chain of changes we need to be able to sip off framing from RSocketStateMachine

Subject: [PATCH 0166/1987] Merged handleUnknownStream and
 handleConnectionFrame methods

Summary:
In this diff I merged 3 different frame processing methods into one. By doing this we are able to:
* move the handleFrame method out of this class in the future diff
* removed extra stream map lookup
* simplified the flow of frame handling

No logic is changed, I just moved code around.

Depends on D7977441.

Subject: [PATCH 0168/1987] Fix rare crash in FrameTransportImpl::onNext()

Summary:
We were depending on the frame processor not having been terminated.  Seems like
in practice it is possible to call FrameTransportImpl::close() first, and then
FrameTransportImpl::onNext() afterwards.

Make onNext() drop any frames it receives.

Subject: [PATCH 0170/1987] Cleanup on RSocketRequester

Summary:
Should not have any behavior changes.

* Added helper to dedup all the `if (isInEventBaseThread())` checks.

* Removed all instances of lambda capture shadowing because I'm paranoid we
  could be using the wrong value somewhere.

Subject: [PATCH 0171/1987] Don't call shared_from_this() in
 RSocketStateMachine::processFrame()

Summary:
We're doing this in case we close out the DuplexConnection, which ends up
deallocating the RSocketStateMachine object and we crash when trying to access
the `this` pointer.

Instead of handling this here, make it FrameTransportImpl's responsibility to
hold onto the RSocketStateMachine reference.

Subject: [PATCH 0172/1987] Preserve error's content

Summary:
RSocket was converting the error payload into string and representation of the error to always a runtime_error.
This generalization causes loss of data.

This diff adds rsocket::ErrorWithPayload struct. This struct extends std::exception.
It keeps the Payload, so it is possible to send/receive encoded data through this Payload.

Where will this help?
As the transport doesn't prune the data, the receiver subscriber can assume the received data is as it is sent from the responder. If the responder has encoded the error, the receiver can decode it.

Subject: [PATCH 0173/1987] Add support for hijacking exception type

Summary:
Add ability to intercept the onError calls and replace the error with another one.
Usages:
 - capability of encoding user defined exceptions sending them over the wire and decoding them on the other side.
 - hide the original error and provide a more user friendly error, improve security.

Subject: [PATCH 0174/1987] Add support for hijacking exception type

Summary:
When a Stream instance is completed with an error, this error will be sent from a server to a client via onError method.
This error will be encoded on the server and decoded on the client.

This new function, errorMap, will perform this encoding and decoding steps.

Subject: [PATCH 0175/1987] Convert SFINAE to static_assert in
 {Map,Filter,Reduce}Operator class templates

Summary: This replaces some instances of SFINAE with `static_assert` in class template parameters. The result is that invalid template arguments will fail early at compile time with a clear compile error. This is because the compiler will select these classes as a match during template substitution even if the supplied template arguments do not constitute a valid input.

Subject: [PATCH 0178/1987] Support sending encoded exception data

Summary:
RSocket converts the error to a string before sending it from server to client.

Prevent this conversion if the exception type is rsocket::ErrorWithPayload.
This will prevent loss of data, so that it will be possible to send/receive raw data, encoded/decoded exceptions.

Subject: [PATCH 0179/1987] Replace std::result_of (deprecated) with
 folly::invoke_result

Summary:
std::result_of is deprecated in C++17 and removed in C++20, so we should be moving away from it in the codebase.

This task removes all uses of std::result_of from fbcode/yarpl/* and replaces them with folly::invoke_result.

Subject: [PATCH 0180/1987] Add RSocketClient::resumeFromConnection()

Summary:
Need this for work in fbcode/live_server/client-connection-management.  I need
to stop using the ConnectionFactory abstraction as it's too opaque, and doesn't
give me access to the events that I want (namely when an HTTP connection gets a
200 response code).

Subject: [PATCH 0181/1987] Fix yarpl installation (#871)

Summary:
Currently yarpl headers are not installed because it is looking in the wrong directory. It was also assuming that a static library was being built with the hard coded ".a" extension, which fails when yarpl is built as a shared library.
Closes https://github.com/rsocket/rsocket-cpp/pull/871

Subject: [PATCH 0183/1987] Relicense RSocket to ASLv2 (#870)

Summary:
In order to move the project to CNCF, we need to
update the license of the library from BSD to
ASLv2.

This PR only modified the license headers of
every file as well as the root LICENSE file.
There was no code modification other than
removing any trailing whitespace.

For the record, here is the script I used:
```

import os
import fileinput

OLD_LICENSE = "// Copyright 2004-present Facebook. All Rights Reserved.\n"
NEW_LICENSE = """// Copyright (c) Facebook, Inc. and its affiliates.
//
// Licensed under the Apache License, Version 2.0 (the "License");
// you may not use this file except in compliance with the License.
// You may obtain a copy of the License at
//
//     http://www.apache.org/licenses/LICENSE-2.0
//
// Unless required by applicable law or agreed to in writing, software
// distributed under the License is distributed on an "AS IS" BASIS,
// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
// See the License for the specific language governing permissions and
// limitations under the License."""

EXTENSIONS = ['.h', '.cpp', '.cc']

for (path, dirnames, filenames) in os.walk('.'):
    for filename in filenames:
        ext = os.path.splitext(filename)[1]
        if ext in EXTENSIONS:
            f = os.path.join(path, filename)
            for line in fileinput.input(f, inplace=True):
                if line == OLD_LICENSE:
                    print(NEW_LICENSE)
                else:
                    print(line.rstrip())
```

+
+      "Object" form shall mean any form resulting from mechanical

+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

Subject: [PATCH 0185/1987] Minor cleanup on TcpConnectionAcceptor

Summary:
Small changes, no real behavior difference.

* Naming threads via folly::ScopedEventBaseThread's ctor instead of manual calls
  to folly::setThreadName().  Give them better names that fit within the
  16-character thread name limit.

* Get rid of TcpConnectionAcceptor::Options ctor, require inputting fields
  manually.

* Drop some unneeded //// delimiter lines.

Subject: [PATCH 0187/1987] Fix races in websocket transport

Summary:
If a websocket connection received frames before WsDuplexConnection::setInput()
was called, it would drop those frames.  The connection also didn't respect flow
control, it would pass frames to the input subscriber as soon as they arrived.
This is what our TCP and HTTP transports do, but they can get away with that
because they're not "framed", i.e. they pass through FramedReader which buffers
everything.  Fix this by adding a payload queue and a credits counter to the
websocket connection handler.

At the same time, fix SetupResumeAcceptor::OneFrameSubscriber from doing
request(INT32_MAX), it only wants the first frame.  We tried and failed to make
this change in the past.  It was previously impossible due to some erroneous
asserts that have now been deleted.  This change is necessary with the flow
control changes to the websocket transport.

Subject: [PATCH 0189/1987] use rvalue-qual Future::get(): pass 5

Summary:
This is part of "the great r-valuification of folly::Future":

* This is something we should do for safety in general.
* Context: `Future::get(...)` means both `Future::get()` and `Future::get(Duration)`
* Using lvalue-qualified `Future::get(...)` has caused some failures around D7840699 since lvalue-qualification hides that operation's move-out semantics - leads to some use of future operations that are really not correct, but are not obviously incorrect.
* Problems with `Future::get(...) &`: it moves-out the result but doesn't invalidate the Future - the Future remains (technically) valid even though it actually is partially moved-out. Callers can subsequently access that moved-out result via things like `future.get(...)`, `future.result()`, `future.value()`, etc. - these access an already-moved-out result which is/can be surprising.
* Reasons `Future::get(...) &&` is better: its semantics are more obvious and user-testable. It moves-out the Future, leaving it with `future.valid() == false`.

Subject: [PATCH 0190/1987] Let createClientFromConnection be called on any
 thread

Summary:
It was asserting that it was always called from the transport's thread.  I can't
see why this is necessary.

Threw in a little bit of refactoring because I couldn't help myself.

Subject: [PATCH 0191/1987] Move Resume{IdentificationToken,Position} and
 StreamId out of internal/Common.h

Summary:
Trying to get the build rules to make sense, and to stop using the monolithic
internal/Common.h as much as possible.

Moves ResumeIdentificationToken to its own module, StreamId to FrameHeader.h,
and ResumePosition to Frame.h.  Those places made the most sense to me as to how
they're used and how complicated ResumeIdentificationToken was.

Deletes getStreamType() as that wasn't used.

Subject: [PATCH 0193/1987] server side http handler allow usages of Proxygen's
 Ex streams.

Summary:
This is the first diff in a series which implements rsocket using proxygen's http Ex streams (child streams).
The feature is disabled by default and so its not affecting any existing systems until its rolled out.

In this diff:
* new Http2ServerControlStreamHandler
* new Framer class extracted from FramedReader
* HttpConnectionFactory is sending ProtocolVersion as a new parameter in the connect(...) method which is needed by the new control stream handlers.

 Future<T>::then() &&.

Summary:
Overall plan to modify Future<T>::then to be r-value qualified and use Future<T>::thenTry or Future<T>::thenValue.

The goal is to disambiguate folly::Future and to improve type and lifetime safety of Future and its methods.

6/n: Codemod rvalue-future<T>.then(...) to rvalue-future<T>.then(...).

Summary:
As part of our migration to skylark, we must remove any skylark incompatible constructs.
One of these constructs is having function definitions in build files (rather than .bzl files)
These series of diffs seek to eliminate the definition by either moving to a sibling :defs.bzl file, removing unneeded functions, or other various methods

the client is disconnected. Want to verify why this happens so need this

Subject: [PATCH 0200/1987] Don't send onDisconnect callback before resuming

Summary:
If we have an open connection when a resume comes in we drop the old
connection as expected. However we also send a onDisconnected callback to the
server which makes it think it should pause the session. It pauses everything
only to unpause it moments later as we were in the process of resuming.

Subject: [PATCH 0201/1987] Reapplying only boiler plate code from D8955216

Summary:
Original commit changeset: 8703161f6d79
The original diff D8955216 landed but caused memory regression and later was reverted in D9262496. In order to find the problematic piece of the original code,
I am splitting it to the boiler plate code and the rest. This diff contains only the boiler plate code change. It is adding a parameter ProtocolVersion to the interface method
ConnectionFactory::connect and all its implementations. No behavior is added or changed.

Subject: [PATCH 0202/1987] fix crash on sendKeepalive fail

Summary:
if the socket connection is closed (or a close is detected) remotely during sendKeepalive then
* stop() gets invoked and
* the connection_ pointer is cleared and
* pending_ is set to false
* but pending_ will still be set to true after this returns, and you'll get a crash as the connection_ shared_ptr is now null.

swapping the order allows stop() to clear the pending_ flag properly if send fails.

 Future<T>::thenValue(task).

Summary:
Overall plan to modify Future<T>::then to be r-value qualified and use Future<T>::thenTry or Future<T>::thenValue.

The goal is to disambiguate folly::Future and to improve type and lifetime safety of Future and its methods.

Codemod:
 * future<T>.then(callable with operator()(not-a-try)) to future<T>.thenValue(callable with operator()(not-a-try)).
 * future<T>.then(callable with operator()()) to future<T>.thenValue(callable with operator()(auto&&)).
 * future<T>.then(callable with operator()(auto)) to future<T>.thenValue(callable with operator()(auto)).

Subject: [PATCH 0204/1987] Reworked and reapplying D8955216

Summary:
The original diff D8955216 caused memory regression in RTGW. In this diff I redesigned the control/child stream handler to not require changes in the Http2StreamHandler (shared class with the Http2ServerStreamHandler, which is currently used in prod).
I also removed the need to use std::deque which was increasing the memory usage. The frame chunk accumulation and buffering is done purely thru IOBufQueue which doesn't require any extra allocations.

The control stream handler implementation is disabled by default and the new code is not touching the http server handlers used in RTGW.

Subject: [PATCH 0205/1987] [] Future<T>::then Future<T>::then(not-try-task) ->
 Future<T>::thenValue(task). - 5/11

Summary:
Part of the larger project to modify Future<T>::then to be r-value qualified and use Future<T>::thenTry or Future<T>::thenValue.

The goal is to disambiguate folly::Future and to improve type and lifetime safety of Future and its methods.

Codemod:
  future<T>.then(callable with operator()(not-a-try)) to future<T>.thenValue(callable with operator()(not-a-try)).
  future<T>.then(callable with operator()()) to future<T>.thenValue(callable with operator()(auto&&)).
  future<T>.then(callable with operator()(auto)) to future<T>.thenValue(callable with operator()(auto)).

Subject: [PATCH 0207/1987] Fix exception slicing error when converting
 exception to exception_wrapper

Summary:
Passing the const& of an exception to the exception_wrapper causes slicing error, if the error is extending std::runtime_error.
Which was the case for this bug.

So, creating an exception_ptr and providing that along with the pure object solves the issue.

Subject: [PATCH 0211/1987] suppress compiler errors about noexcept name
 mangling changes

Summary:
Stop gcc 7+ from complaining about the fact that function name mangling of
noexcept functions changes between the C++14 and C++17 dialect options.

Note that there are still a number of other compiler warnings emitted about
signed/unsigned comparison mismatches and unused function parameters.
However those are treated simply as warnings rather than errors and do not
cause the build to fail.

Subject: [PATCH 0214/1987] travis: build with clang-6.0 instead of clang-4.0

Summary:
folly does not compile with clang versions older than 6.0 any more.

This also changes the travis.yml file to set CC and CXX in the environment
so that folly and gmock get built with the intended compiler instead of being
compiled with the default system compiler (gcc 4.8.4 on Ubuntu trusty).  folly
no longer compiles with gcc 4.8 either.

Subject: [PATCH 0215/1987] do not use jemalloc with clang on Travis CI builds

Summary:
The Travis CI builds use Ubuntu trusty, and the version of jemalloc that it
ships with is 4+ years old and does not work with clang+libstdc++.  clang
thinks that jemalloc's definitions of memalign and other functions conflict
with those provided by libstdc++.  This was fixed in upstream jemalloc in
2015 (jemalloc commit ae93d6bf3), but this fix is not available in Ubuntu
trusty.

This hasn't caused problems until now since the autoconf-based build of folly
did not use jemalloc unless arguments were supplied to configure explicitly
asking for jemalloc to be used.  The CMake-based build of folly uses jemalloc
automatically if it is available.

Subject: [PATCH 0216/1987] build and install OpenSSL 1.1.1 during Travis CI
 builds

Summary:
rsocket-cpp requires `folly::SSLContext::setAdvertisedNextProtocols()`
Recent versions of folly only support this function when using OpenSSL 1.0.2
or greater.

Unfortunately the newest Ubuntu distribution supported by Travis CI is 16.04,
which only has OpenSSL 1.0.1f.

This updates the Travis CI configuration to download and build OpenSSL 1.1.1
so that rsocket can compile successfully with current versions of folly.

Ideally we should probably cache the OpenSSL build installation between
builds, but I'll leave that for a subsequent diff.

Subject: [PATCH 0217/1987] fail the build if setAdvertisedNextProtocols() is
 not available

Summary:
As of D10110626 `folly::SSLContext` only provides
`setAdvertisedNextProtocols()` when `FOLLY_OPENSSL_HAS_ALPN` is true.  This
is only true when using OpenSSL 1.0.2 or greater.

The rsocket code requires this method in order to work, so fail the build if
the versions of OpenSSL is too old.

Subject: [PATCH 0218/1987] find folly using its installed cmake config file

Summary:
Find folly using its installed CMake configuration file, and delete the custom
FindFolly.cmake file that was being used previously.  The FindFolly.cmake file
did not list all dependent libraries necessary to link statically against
folly.  Linking against folly as a shared library is not recommended, as
folly provides no binary compatibility guarantees between changes.  folly's
current CMake-based build only builds it as a static library by default.

This also changes the build process to build folly with CMake rather than its
deprecated autotools-based build when RSOCKET_INSTALL_DEPS or INSTALL_FOLLY is
set.  Note that the build now happens as part of the `cmake` step, since folly
must be installed before we call `find_package()` to find folly.

This also updates the code to always use the current folly master branch,
rather than being pinned to v2018.06.25.00.  This should hopefully help catch
breakage's in the open source rsocket-cpp build much sooner.

Subject: [PATCH 0226/1987] Export rsocket, yarpl CMake targets (#877)

Summary:
Pull Request resolved: https://github.com/rsocket/rsocket-cpp/pull/877

* Adds a flag to skip building tests.
* Exports rsocket::ReactiveSocket and yarpl::yarpl targets, so that downstream
  packages can pick them up with a find_package(rsocket) or a find_package(yarpl)
* Do not explicitly call set(CMAKE_BUILD_TYPE) in yarpl CMakeLists -- this will break the installation if yarpl was installed transitively through rsocket, and rsocket was configured with a different build type (e.g. `cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo /path/to/rsocket`)

fbthrift perf examples need this to compile properly.

Subject: [PATCH 0227/1987] Remove HHWheelTimer::Callback::getCurTime and its
 overrides

Summary:
This function is being overridden in only one class (with a duplicate) that is used in only a single test with no clear semantics of what is being tested (the only effect it has is that cascading logic will see 0, which can be achieved with a simple sleep).

Removing this customization point allows us to avoid doing additional call to steady_clock::now per each timeout (stacked diff) and thus improving performance by ~2x (measured as part of Fibers benchmark after migrating FiberManager to use HHWheelTimer, also stacked).

Subject: [PATCH 0228/1987] fix detection and dep on glog::glog when building
 via cmake

Summary:
folly exports a dependency on `glog::glog`.  That causes dependent packages to also depend implicitly on glog::glog with no way to resolve what that means, resulting in errors like this:

```
CMake Error at CMakeLists.txt:106 (add_library):
  Target "wangle" links to target "glog::glog" but the target was not found.
  Perhaps a find_package() call is missing for an IMPORTED target, or an
  ALIAS target is missing?
```

We cannot rely on `glog` having installed its configuration for a simple `find_package(glog CONFIG)`; the version of `glog` provided by some versions of ubuntu doesn't install a `.cmake` file for this.

That means that we need to detect it for ourselves.

This diff enhances the `FindGlog.cmake` script to define a `glog::glog` target so that we can consistently depend upon it throughout the set of related packages.

It is unfortunate that we have duplication of the `FindGlog.cmake` files across these projects; a follow up diff could place these in eg: fbcode_builder and arrange to have shipit to copy them to the right place at shipit time.

Subject: [PATCH 0229/1987] rsocket: remove -pedantic from the cmake build

Summary:
This was a real PITA to track down.  The problem is this:

* Ubuntu 16 has a version of jemalloc installed that doesn't annotate
  `malloc` with `throw ()`.
* Folly unconditionally pulls in that jemalloc header
* rsocket/yarpl, when compiling with `-pedantic` enabled, generate
  a compiler error about the difference between the `stdlib.h`
  `malloc() throw();` and the jemalloc `malloc();`

I tried to deal with this by probing for the conflict in the folly
cmake rules (D13795199), but cannot do so without turning on `-pedantic`
for folly and potentially propagating that into all downstream consumers of
folly.

`-pedantic` doesn't generally provide a lot of value and is hard
to reason about which individual checks are being enforced, and
importantly, doesn't provide a way to enable/disable those checks
for sections of code that should be excepted from those rules.

So, the easiest thing to do is remove its use from rsocket.

This should allow more direct testing of changes without waiting for things to land on github first.

As part of this, to avoid a conflict between the deps that bistro downloads and those used by
the rest of the fbcode builder CI, I've updated the version of gtest used by bistro.

Subject: [PATCH 0232/1987] rsocket: improve detection of gflags in cmake build

Summary:
I'm seeing a linker error when watchman tries to pull in these
deps on macos

```
ld: library not found for -lgflags
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [yarpl/yarpl-playground] Error 1
make[1]: *** [yarpl/CMakeFiles/yarpl-playground.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....
```

(note that yarpl is pulled in as a subdir of rsocket-cpp in the github flavor
of the build, and it uses the cmake defs from rsocket)

This diff switches rsocket to use the same technique as used by folly to locate
this dep; note that glog depends on gflags too, so I've switched the order
of the probes for these packages.

Subject: [PATCH 0235/1987] Stop checking EventBase::runInEventBaseThread
 result

Summary:
[Folly] Stop checking `EventBase::runInEventBaseThread` result, as the function will soon be changed not to return any result.

It returned `false` when failing to enqueue a task. But it cannot really fail anyway besides allocation failure, unless in the `EventBase` destructor and while draining and the `AlwaysEnqueue` variant is called.

Subject: [PATCH 0237/1987] Support cancellation for subscribers created via
 convenience API

Summary:
`Flowable` provides a number of convenience `subscribe` methods, which take lambdas as parameters. Unfortunately, in its current form, usage of this API for practical purposes is quite limited, due to lack of cancellation support for such subscriptions: `Subscription` object is not exposed outside, so there's no way to call `cancel`. However cancellation is often required for long-lived streams, e.g. when service needs to shutdown gracefully and needs to cancel stream before cleaning up. Because of this, whenever cancellation is necessary, the only possible approach is to create custom `Subscriber` to gain access to `Subscription`. Even when subclassed from `BaseSubscriber`, this requires extra work to properly handle credits in `onNextImpl`, similar to how `details::Base` does it.

This diff proposes a solution to this problem, by adopting approach taken by RxJava, where convenience `subscribe` methods return `Disposable` object. Calling `Disposable::dispose` cancels the subscription.

Subject: [PATCH 0238/1987] (Thrift/Streaming) add support for async generating
 in StreamGenerator

Summary: Currently StreamGenerator can only generate element in a sync way, the return type of the input lambda will be folly::Optional<T>, folly::none signal the end of the Stream. This diff add async support for return type of folly::SemiFuture<folly::Optional<T>>, where future with folly::none signal the end of the Stream. With the help of futures::reduce, the return value should come back still in Stream's order though.

Subject: [PATCH 0240/1987] 
 AsyncServerSocket::AcceptCallback::connectionAccepted to NetworkSocket

Summary: This is a largely automated codemod that shifts `folly::AsyncServerSocket::AcceptCallback::connectionAccepted` to taking a `NetworkSocket` rather than a file descriptor. This needs to be done as a single atomic change to avoid breaking things.

Subject: [PATCH 0241/1987] Eliminate accessing Connection after the
 KeepAliveTimer is destroyed

Summary:
KeepAliveTimer causes RSocket to crash as it tries to access Connection_ object, possible after the destruction.
It shows that the `generation_` check did not work for this case.

As seen, there is already a check to eliminate such failure by taking a reference to the connection_, before calling a callback.
So, make it more generalized.

Ref crash stack trace: P61856171

+## Debugging Docker builds
+
+To debug a a build failure, start up a shell inside the just-failed image as
+follows:
+
+```
+docker ps -a | head  # Grab the container ID
+docker commit CONTAINER_ID  # Grab the SHA string
+docker run -it SHA_STRING /bin/bash
+# Debug as usual, e.g. `./run-cmake.sh Debug`, `make`, `apt-get install gdb`
+```
+
+## A note on Docker security
+
+While the Dockerfile generated above is quite simple, you must be aware that
+using Docker to run arbitrary code can present significant security risks:
+
+ - Code signature validation is off by default (as of 2016), exposing you to
+   man-in-the-middle malicious code injection.
+
+ - You implicitly trust the world -- a Dockerfile cannot annotate that
+   you trust the image `debian:8.6` because you trust a particular
+   certificate -- rather, you trust the name, and that it will never be
+   hijacked.
+
+ - Sandboxing in the Linux kernel is not perfect, and the builds run code as
+   root.  Any compromised code can likely escalate to the host system.
+
+Specifically, you must be very careful only to add trusted OS images to the
+build flow.
+
+Consider setting this variable before running any Docker container -- this
+will validate a signature on the base image before running code from it:
+
+```
+export DOCKER_CONTENT_TRUST=1
+```
+
+Note that unless you go through the extra steps of notarizing the resulting
+images, you will have to disable trust to enter intermediate images, e.g.
+
+```
+DOCKER_CONTENT_TRUST= docker run -it YOUR_IMAGE_ID /bin/bash
+```

+# Easy builds for Facebook projects
+
+This is a Python 2.6+ library designed to simplify continuous-integration
+(and other builds) of Facebook projects.
+
+For external Travis builds, the entry point is `travis_docker_build.sh`.
+
+
+## Using Docker to reproduce a CI build
+
+If you are debugging or enhancing a CI build, you will want to do so from
+host or virtual machine that can run a reasonably modern version of Docker:
+
+``` sh
+./make_docker_context.py --help  # See available options for OS & compiler
+# Tiny wrapper that starts a Travis-like build with compile caching:
+os_image=ubuntu:16.04 \
+  gcc_version=5 \
+  make_parallelism=2 \
+  travis_cache_dir=~/travis_ccache \
+    ./travis_docker_build.sh &> build_at_$(date +'%Y%m%d_%H%M%S').log
+```
+
+**IMPORTANT**: Read `fbcode_builder/README.docker` before diving in!
+
+Setting `travis_cache_dir` turns on [ccache](https://ccache.samba.org/),
+saving a fresh copy of `ccache.tgz` after every build.  This will invalidate
+Docker's layer cache, foring it to rebuild starting right after OS package
+setup, but the builds will be fast because all the compiles will be cached.
+To iterate without invalidating the Docker layer cache, just `cd
+/tmp/docker-context-*` and interact with the `Dockerfile` normally.  Note
+that the `docker-context-*` dirs preserve a copy of `ccache.tgz` as they
+first used it.
+
+
+# What to read next
+
+The *.py files are fairly well-documented. You might want to peruse them
+in this order:
+ - shell_quoting.py
+ - fbcode_builder.py
+ - docker_builder.py
+ - make_docker_context.py
+
+As far as runs on Travis go, the control flow is:
+ - .travis.yml calls
+ - travis_docker_build.sh calls
+ - docker_build_with_ccache.sh
+
+This library also has an (unpublished) component targeting Facebook's
+internal continuous-integration platform using the same build-step DSL.
+
+
+# Contributing
+
+Please follow the ambient style (or PEP-8), and keep the code Python 2.6
+compatible -- since `fbcode_builder`'s only dependency is Docker, we want to
+allow building projects on even fairly ancient base systems.   We also wish
+to be compatible with Python 3, and would appreciate it if you kept that
+in mind while making changes also.

+
+This is a small DSL to describe builds of Facebook's open-source projects
+that are published to Github from a single internal repo, including projects
+that depend on folly, wangle, proxygen, fbthrift, etc.
+
+This file defines the interface of the DSL, and common utilieis, but you
+will have to instantiate a specific builder, with specific options, in
+order to get work done -- see e.g. make_docker_context.py.
+
+== Design notes ==
+
+Goals:
+
+ - A simple declarative language for what needs to be checked out & built,
+   how, in what order.
+
+ - The same specification should work for external continuous integration
+   builds (e.g. Travis + Docker) and for internal VM-based continuous
+   integration builds.
+
+ - One should be able to build without root, and to install to a prefix.
+
+Non-goals:
+
+ - General usefulness. The only point of this is to make it easier to build
+   and test Facebook's open-source services.
+
+Ideas for the future -- these may not be very good :)
+
+ - Especially on Ubuntu 14.04 the current initial setup is inefficient:
+   we add PPAs after having installed a bunch of packages -- this prompts
+   reinstalls of large amounts of code.  We also `apt-get update` a few
+   times.
+
+ - A "shell script" builder. Like DockerFBCodeBuilder, but outputs a
+   shell script that runs outside of a container. Or maybe even
+   synchronously executes the shell commands, `make`-style.
+
+ - A "Makefile" generator. That might make iterating on builds even quicker
+   than what you can currently get with Docker build caching.
+
+ - Generate a rebuild script that can be run e.g. inside the built Docker
+   container by tagging certain steps with list-inheriting Python objects:
+     * do change directories
+     * do NOT `git clone` -- if we want to update code this should be a
+       separate script that e.g. runs rebase on top of specific targets
+       across all the repos.
+     * do NOT install software (most / all setup can be skipped)
+     * do NOT `autoreconf` or `configure`
+     * do `make` and `cmake`
+
+ - If we get non-Debian OSes, part of ccache setup should be factored out.

Subject: [PATCH 0243/1987] Re-re-sync

Note that shipit wants to restore the `/build` line to the `.gitignore`
which we know is bad.  I'm not sure why it wants to do that even after
removing that line from the version of the file in fbsource; perhaps
shipit is looking at an earlier commit?

Let's try this and see if it makes shipit any happier.

Subject: [PATCH 0251/1987] Allow LogDevice to build without Submodules (#71)

Summary:
As a step in the plan to migrate LogDevice to using fbcode_builder as
the primary build method, allow LogDevice to build without submodules.
In place of the self compiled modules, the CMake scripts will look in
the system (or provided prefix locations) and use precompiled modules
there. Users can then use fbcode_builder to ensure those required
modules are built and available.

* Use new 'folly_test_util' library rather than referencing sources
directly

Subject: [PATCH 0264/1987] folly:wangle: fixup libevent detection and export

Summary:
I finally got to the bottom of the weird `-levent` or `event.lib`
linker errors that crop up in the cmake builds.

The issue is that if you have installed a recent libevent it deploys
a cmake CONFIG package that exports just a bare `event` target as the
dep on libevent.  This is unfortunate because it is interpreted as
meaning `-levent` with no library path, which for an installation
of libevent that is not in the default path will result in linker
errors in libraries downstream of folly.

To resolve this, I've given the common `FindLibEvent.cmake` file
(that was derived from the folly library of the same name) a similar
treatment to the recent changes to find glog and taught it how to
locate libevent from a config package and to fall back on a basic
include/library check.

If we find an `event` target then we extract the actual library
path from it and export that.

I've removed folly's and wangle's own FindLibEvent.cmake so that it will pick
up the common library which gets shipit sync'd out to
https://github.com/facebook/folly/blob/master/CMake/FindLibEvent.cmake
and https://github.com/facebook/wangle/blob/master/build/fbcode_builder/CMake/FindLibEvent.cmake

 * to ensure that the executor is not lost and the returned Future is still bound to an executor

Subject: [PATCH 0275/1987] Cut fbcode_builder dep for thrift on krb5

Summary: [Thrift] Cut `fbcode_builder` dep for `thrift` on `krb5`. In the past, Thrift depended on Kerberos and the `krb5` implementation for its transport-layer security. However, Thrift has since migrated fully to Transport Layer Security for its transport-layer security and no longer has any build-time dependency on `krb5`. Clean this up.

 annoyances

Summary:
When pulled in as an external project into an environment
that has changed the default cmake policy, the trick we're using
to extract the full library path errors out.  This works around
that issue by saving the policy settings and then setting them
how we need them before restoring them after we're done.

 AsyncServerSocket::AcceptCallback::connectionAccepted to NetworkSocket
 (attempt #2)

Summary:
The file descriptor API here needs to go away, so switch this API to NetworkSocket

It is expected that this commit will cause a number of Open Source projects to temporarily show up as broken. This is due to the fact that not all projects get synced to Github at the exact same time, so the builds may temporarily be fetching an older version of it's dependencies than it needs to :) It should fix itself quickly.

Subject: [PATCH 0289/1987] fbcode_builder support for using Python virtualenv
 (#76)

Summary:
Needs to be enabled by option PYTHON_VENV in the config.

shell_builder.py sets up the venv and uses it once; calling activate

For docker we set ENV; resulting in the virtual environment being present
when the resulting container is run as well as at build time. This is also cleaner
and easier to follow than re-asserting on each RUN step.

For Lego builder we need to source activate on each command as environment
will not persist between commands.

While man on the posts say it makes no sense to use virtualenv within docker
container, this method simplifies the process considerably as we can rely on the
name pip being valid and we don't need to either ensure we are root or pass the
--user flag to pip and setuptools.

Subject: [PATCH 0299/1987] use fb_github_project_workdir() for folly

Summary:
Update the folly spec to use `fb_github_project_workdir()` rather than just
`github_project_workdir()`.

This shouldn't have any impact for external github-based builds, but for our
internal continuous integration builds this should make builds for downstream
projects pick up the correct local version of folly that matches the commit of
the downstream project that is being built.

This behavior was unintentionally changed to not use the `fb_*` version in
D10520960.

 parser

Summary:
As part of folding getdeps into fbcode_builder, this
expression parser is needed to allow constrained and deterministic
conditionals in the manifest file format.

For example, the watchman manifest will use this cargo-inspired syntax
for system dependent sections:

```
[dependencies]
folly

[dependencies.not(os=windows)]
thrift
```

Subject: [PATCH 0330/1987] fbcode_builder: add manifest file parser

Summary:
Adds a parser for manifest files that describe projects
that may be either 1st party or 3rd party.

A selection of manifest files appears in a later diff in this stack.

This diff provides the raw parser and a couple of low level helpers.
It also defines a mechanism for validating the schema to help catch
structural (rather than semantic) issues with manifest file contents.

Later diffs in the stack add helpers for accessing the data in
a higher level way.

Subject: [PATCH 0331/1987] fbcode_builder: add manifest files for some
 dependencies

Summary:
These are ported over from the logic in the watchman and eden getdeps
scripts, with additions to help bootstrap a build environment.

These are sufficient to build watchman with thrift support on windows, mac and
linux, and eden on mac and linux when combined with the getdeps code that
follows in later diffs in this stack.

Subject: [PATCH 0332/1987] fbcode_builder: getdeps: add envfuncs.py

Summary:
Add some helpers for manipulating environment variables
that will hold either compiler flags or paths.

These are used in later diffs when setting up arguments/environment
for eg: cmake.

Subject: [PATCH 0334/1987] fbcode_builder: getdeps: add run_cmd() function

Summary:
This runs a command, raising an exception if it exits with a non-zero error status.

It prints out the arguments in a mostly copy-and-pasteable form, with PATH-like
env vars pretty printed to make it easier to see what is being invoked; here's
an example of how cmake is being invoked later in this stack:

```

Subject: [PATCH 0338/1987] fbcode_builder: getdeps: define the Fetcher
 interface

Summary:
Fetchers are used to fetch a source directory from a
source defined in a manifest file.

More details can be found in comments on the various methods.

The Manifest class offers a create_fetcher method for constructing
an appropriate fetcher.  This is just a stub in this commit, but
will expand over the course of the next few diffs as concrete
fetcher instances are added.

Subject: [PATCH 0341/1987] fbcode_builder: getdeps: add ShipitTransformer
 fetcher

Summary:
This fetcher knows how to take a 1st party FB project
from fbsource and transform it to the same shape as our github
repos using ShipIt.  The transformation creates a transformed
mirror of the code in scratch space (rather than mutating fbsource
directly).

This can only be used in environments where shipit is available.
A later diff implements an alternative that works in more environments.

Subject: [PATCH 0342/1987] fbcode_builder: getdeps: add
 SimpleShipitTransformer fetcher

Summary:
This fetcher knows how to transform a 1st party project
from fbsource into approximately the same shape as ShipIt produces
for the github repo mirrors.  It does this by reading shipit
mapping information from the manifest file for the project.

Since this fetcher uses data in the manifest and is implemented
directly in the getdeps codebase, it is suitable for iterating
on the opensource builds directly out of fbsource on both devservers
and laptops inside FB.

Note: checking out 'FETCH_HEAD'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 470344d Merge pull request #1479 from facebook/visualTest

Subject: [PATCH 0344/1987] fbcode_builder: getdeps: add list-deps subcommand

Summary:
While the command isn't necessarily super useful
on its own, it does show that the plumbing for walking the
deps is functioning, and that is important when it comes
to building.

The output lists the projects in the order that they
would be built.

The `fetch` command has been augmented to add a `--recursive`
flag that uses the same mechanism to recursively fetch
the dependencies.

Subject: [PATCH 0347/1987] fbcode_builder: getdeps: add AutoconfBuilder

Summary:
the autoconf builder performs an out-of-source build using
the autoconf suite to configure the build rules.

The `autoconf.args` section from the manifest is passed to the `./configure`
command line.

If an `autogen.sh` script is present then it will be used to regenerate
a missing `configure` script, otherwise we'll try `autoreconf`.

Subject: [PATCH 0348/1987] fbcode_builder: getdeps: add CMakeBuilder

Summary:
the cmake builder knows how to use cmake to configure a build
for (preferably) and out-of-src build.  The `cmake.defines` section of
the manifest is used to pass `-Dkey=value` options to the cmake configure
command line.

We prefer to use `ninja` to execute the build so that we can use more
cores than 1 on Windows and just for consistency across platforms
with mac and linux.

Summary:
this builder is used to bootstrap the ninja build tool.

On Windows and mac the manifest for ninja is set to download a pre-built executable.
While pre-built executables are available for linux they aren't portable enough
for our purposes so we need to be able to build it for ourselves.

Summary:
the openssl builder knows how to perform the non-standard
configuration and build steps to build openssl.

On Linux systems the manifests for our projects don't mention
openssl, causing them to pick up the system openssl.

On Mac, apple don't ship openssl headers so we need to build our own.
On Windows there is no standard openssl installation so we also need
to build our own.

As a result, this builder only works on windows and mac.

Subject: [PATCH 0351/1987] fbcode_builder: getdeps: add Boost builder

Summary:
the boost builder knows how to perform the non-standard
configure and build for boost.

Ideally we'd just build this statically and be happy but there are
some nuances I've observed while building on different platforms:

* One of our projects (thrift or wangle) explicitly requests static
  boost linkage for reasons unspecified
* on darwin the install_name is broken when building dynamic libs

For the sake of expediency in getting getdeps up and running, the
solution for the moment is to build static on posix systems and
build both static and shared on windows systems.

Summary:
this could do with a better name; the NopBuilder doesn't actually
build anything, but instead copies some files to the destination location.

This is used together with eg: cmake to install pre-built binaries downloaded
from a tarball.

Subject: [PATCH 0353/1987] getdeps: add build subcommand

Summary:
adds the command that is used to drive a build.

The dependencies of the named project are computed using
the same mechanism behind the `list-deps` subcommand.
If a manifest specifies that it uses the `cmake` builder then
a dependency on `cmake` is synthesized so that we can download
a recent version of cmake ahead of time.

The build command uses the fetcher to update the src and then
executes the builder.

This fixes a TODO; in our CI environment we want to use the
real shipit, so we'll use this flag to make that happen.

Summary:
Adds a `test` subcommand that runs the tests for project.
We're mostly interested in the 1st party facebook projects for this.

The `sandcastle` flow will run the `test` subcommand just for the "leaf" project--the one named on the command line.

Subject: [PATCH 0358/1987] fbcode_builder: getdeps: add `sandcastle`
 subcommand

Summary:
This command schedules a facebook specific sandcastle job for the current
commit in your repo for each of the platforms we have support for in
sandcastle.

You can use `--dry-run` to have it print out the job specs.

To support this, I've moved around some of the support utilities
to make it easier to import them.

Subject: [PATCH 0359/1987] fbcode_builder: getdeps: beef up hash computation

Summary:
previously, a relatively lame hash was computed to use
for the build directory based on some hash of the source directory.
That was good enough to get things off the ground, but in the
interest of being able to cache the build outputs and safely
invalidate them we need a slightly more rigorous implementation.

This diff computes a hash based on the manifest contents and
relevant environmental factors.

The hash is used to name the build directory which will ultimately
be cached eg: using the travis/appveyor cache directory configuration
and some other means for the FB internal CI.

The hash needs to be sufficient that we change the hash when
the manifests change.  We can tolerate a false positive change
in hash (it just means that a build will take longer), but
cannot tolerate a false negative (which would result in an
incorrect build).

Summary:
If `testpilot` is available, generate a buck compatible json file describing the available test binaries and feed that to testpilot to have it run the tests.

A later (yet to be written) diff will be able to pass appropriate flags down to testpilot in continuous runs and that will allow testpilot to auto-disable and file tasks for tests in the opensource builds.

 `show-source-dir` commands

Summary:
This prints out the installation or source prefix for a given project.
This is useful in eg: packaging scripts to figure out where they can
find the built artifacts.

Subject: [PATCH 0363/1987] eden: getdeps: add fb-mercurial dep to enable
 treemanifest

Summary:
In order to pull in the treemanifest and other libraries
from our mercurial repo, add a manifest file for it, and then
adjust the logic in our cmake module to look for it.

The fb-mercurial manifest just copies the source tree to the
installation dir.  In the future, we could teach it to invoke
the build for real.

Subject: [PATCH 0364/1987] fbcode_builder: getdeps: add LFS caching for
 ArchiveFetcher

Summary:
When running in FB infra, prefer to download from our local LFS
server rather than going out to the internet.

Fall back to a normal internet download if the LFS get fails for some reason.

Upload to LFS after successfully verifying the hash for the downloaded archive.

Add a subcommand that performs a fetch for all possible platforms so that it
is easier to ensure that the lfs-pointers file is up to date.

Summary:
Previously, we were using autoconf to build sqlite,
but that isn't available on Windows.  Instead, here's a builder
that generates a little cmake configuration for building and
installing sqlite.

Using cmake for this means that we can test the same builder
on all platforms that need to pull in sqlite.

Subject: [PATCH 0366/1987] fbcode_builder: getdeps: add `build --no-deps` flag

Summary:
This is useful especially on Windows where the up-to-date
checks for the dependencies take a long time.

The idea is that you might run this to start:

```
$ getdeps.py build eden
```

and then while in the edit/debug/build iteration cycle:

```
$ getdeps.py build --no-deps eden
```

Subject: [PATCH 0372/1987] (Thrift/Streaming) max batch process size in async
 StreamGenerator

Summary: The previous StreamGenerator for future has a flaw. The number of concurrent Futures issued bonded to the credit requested from client. In the extreme case if client send request with kNoFlowControl which equals to int64_max will trigger creating this many number of futures and hang the server forever. This comes down to when creating stream, server side owner need to specify a max number of futures that can be issued out concurrently. For coroutine async generator use case this number will always be one.

Subject: [PATCH 0377/1987] getdeps: introduce `build --enable-tests` option

Summary:
This controls whether tests are built or not.
They are not built by default.  When `--enable-tests` is turned on,
tests are enabled for the named project only, not all of the deps.
This results in a faster build, because eg: the number of tests in
folly is very large and consumers of folly don't want to spend so
much time waiting to build tests when really all they want to do
is build their own project.

Subject: [PATCH 0386/1987] getdeps: respect cmake WORKING_DIRECTORY for tests

Summary:
the cmake `add_test` and related functions allow specifying
the WORKING_DIRECTORY to use for tests.  We weren't respecting this
value, so this diff looks up the WORKING_DIRECTORY from the ctest
json info and adjusts the buck test info json blob that we pass
on the testpilot.

Since that interface only allows passing an argv array, we use
the `cmake -E chdir` command to run a command in a specified
directory in a portable manner.

```
Traceback (most recent call last):
  File ".\opensource\fbcode_builder\getdeps.py", line 400, in <module>
    sys.exit(main())
  File ".\opensource\fbcode_builder\getdeps.py", line 393, in main
    return args.func(args)
  File ".\opensource\fbcode_builder\getdeps.py", line 236, in run
    change_status = fetcher.update()
  File "C:\open\fbsource\fbcode\opensource\fbcode_builder\getdeps\fetcher.py", line 451, in update
    return mapping.mirror(self.build_options.fbsource_dir, self.repo_dir)
  File "C:\open\fbsource\fbcode\opensource\fbcode_builder\getdeps\fetcher.py", line 400, in mirror
    f.write(name + "\n")
  File "C:\Python36\lib\encodings\cp1252.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode characters in position 104-105: character maps to <undefined>
```

and this is caused by a file in libgit2: https://github.com/libgit2/libgit2/blob/master/tests/resources/status/%E8%BF%99, which is intended to test handling non-ASCII path.

Python on Windows will write file in cp1252 encoding by default, which does not contain that Chines character. (Caveat: that file on my system doesn't have the correct file name as well, it is being encoded in IBM861 for some reason. However the characters in IBM861 does not exist in CP1252 either)

Summary:
This diff updates docker os_image to ubuntu18 and gcc7 in travis settings.
The dependencies that we work with internally (e.g. gcc7, boost and so on) are not present in the ubuntu-16.04. Further, the support for gcc5 is going away. So maintaining this compatibility for these platforms is painful, especially for new projects, such as mvfst.

 canellation in AsyncGenerator stream

Summary:
The `toAsyncGenerator()` function now takes an optional `CancellationToken` parameter that allows the consumer to cancel a stream when a consumer is currently suspended waiting for the next value.

Adds a guard in EmitterSubscription: to handle the case where a call to onError()/onValue()/onComplete() comes in after the stream has been cancelled and the inner subscription has been released.

Subject: [PATCH 0406/1987] getdeps: allow tagging a build with its schedule
 type

Summary:
The schedule type is used to differentiate between a build run during
code review (and thus runs code that isn't yet in the master branch),
from continuous or other types of run that operate on landed code.

This doesn't change any behavior yet; this diff just adds
the plumbing to pass down an optional arbitrary schedule type string
from the CI system.

In the future, we'll use the schedule type to influence the behavior
of running tests.

Subject: [PATCH 0409/1987] watchman: fixup FB internal mac packaging

Summary:
with the reshuffling around getdeps.py, and changes in folly/thrift/wangle,
our internal package stopped building.  This diff brings it back to life.  It is
a little bit interwined:

* Introduce a `--facebook-internal` switch to getdeps that causes `fb` in the
  build context to be set to `on` rather than `off`.  This allows specifying
  options in the manifest that are FB specific.
* Introduce cmake options to control the WATCHMAN_STATE_DIR and whether cmake
  should attempt to create WATCHMAN_STATE_DIR when it is installed.
* For FB specific builds on macOS, set the state dir to match our existing location
  and disable creation of WATCHMAN_STATE_DIR because that will ultimately be
  handling during package installation and we don't have privs for that on
  the machine generating the package.
* Adjust Facebook CI scripts to use getdeps for building and testing watchman

Subject: [PATCH 0419/1987] Reuse old build dir on Windows

Summary:
getdeps.py's find_existing_win32_subst_for_path function tries to reuse an existing build directory alias. (On Windows, the build directory is aliased to a drive letter to shorten paths.) If this function does not find and existing build directory alias, getdeps.py invalidates many of its caches.

On my Windows machine, find_existing_win32_subst_for_path always fails, so all of my builds are super slow. This happens because find_existing_win32_subst_for_path is given a path with a lower-case drive letter ("c:\users\..."), but the subst command returns paths with an upper-case drive letter ("C:\users\...").

When comparing paths, use ntpath.normpath. This makes the comparison case-insensitive for drive letters. (It also makes the comparison case-insensitive for other path components.)

On Linux and macOS, this diff should not change behavior.

Subject: [PATCH 0422/1987] getdeps: configure testpilot to use collections and
 tag tests

Summary:
This should enable test pilot to skip broken/flakey tests.

The `--tag-new-tests` flag is only appropriate for code that has been
landed on master and is used by the FB infra to classify new tests
appropriately.

For continuous builds we use a test collection with different parameters
from the normal developer facing flow so that the infra can re-assess
their status and enable/disable high-signal/noisy tests.

Subject: [PATCH 0439/1987] fbcode_builder: getdeps: fboss: add iproute2
 fetcher

Summary:
This is towards getting open source FBOSS to build using fbcode_builder.
iproute2 is one of the dependencies for FBOSS. This patch adds a manifest file
to build the specific version of iproute2 needed for FBOSS.

Additionally, the default git clone depth of 100 is insufficient for the
version of iproute2 FBOSS depends on. Thus, this patch extends the git SCHEMA
to add optional argument depth. The default remains 100.

The usual /configure --prefix does not work for iproute2. Thus, we need to add
a custom builder that:
  - copies sources to build directory, builds, and
  - installs to installed directory using DEST_DIR.
  - it must also explicitly copy include from build dir to install dir

Subject: [PATCH 0440/1987] fbcode_builder: getdeps: fboss: add OpenNSL fetcher

Summary:
This is towards getting open source FBOSS to build using fbcode_builder.
OpenNSL is one of the dependencies for FBOSS.

OpenNSL is github repository with headers and prebuilt opaque library. Thus, we
can't/don't need to build it. Thus, OpenNSL manifest uses NopBuilder.

fbcode_builder expects the library to be in installed/lib and headers to be in
installed/include, but OpenNSL lib structure is different.  Thus, add explicit
[install.fields] rule for bin/wedge => lib. Once a rule(s) is provided, we must
provide rule(s) for all, so add rule for include => include as well.

Subject: [PATCH 0456/1987] fbcode_builder: getdeps: fboss: extend iproute2
 builder to copy lib/*

Summary:
D15588809 introduced manifest and customer builder for iproute2. While the
Iproute2Builder copies include/* from build to install directory, it does not
copy lib/* which contains the libnetlink.a

As a result, the build system looks up libnetlink.a on local machine (which it
may not find).

Fix it by explicitly coping lib/* as well.

Subject: [PATCH 0457/1987] fbcode_builder: getdeps: fboss: update libcurl
 manifest to disable lldp

Summary:
D15683387 introduced manifest for libcurl and used cmake instead of autoconf
(rationale: having cmake build curl would make it easy as we want curl to build
on windows and macos).

if libcurl finds ldap.h, then it builds with ldap enabled.
On my devserver, ldap library is not installed, and thus libcurl builds without
it, and links with FBOSS binaries fine.

In sandbox, ldap seems to be installed, thus libcurl builds with ldap. However,
linking fails for FBOSS binaries as those don't link against ldap - FBOSS does
not depend on ldap.

Thus, we need a way to configure libcurl with ldap disabled. [cmake.defines]
CURL_DISABLE_LDAP=OFF, does not quite do it. Thus, am going with autoconf, with
args --disable-ldap for now for Linux and cmake for non-Linux environments.

Summary:
The previous diffs in the stack add fbcode_builder manifests for FBOSS
dependencies iproute2 and OpenNSL. The other FBOSS dependencies already have
fbcode_builder support. Thus, add FBOSS manifest.

Additionally, this patch also modifies fboss CMakeLists.txt to get FBOSS to
build using fbcode_builder.

 thrift files

Summary:
This is a hack for now to allow fbsource-based watchman getdeps builds to
succeed.  In the long run we need to update Watchman's CMakeLists.txt to
depend on a proper EdenFS build, rather than copying Eden's thrift files into
Watchman's source tree.

Summary:
The source we were downloading from (netfilter.org) should work, but
unfortunately, is donw. This is causing getdeps FBOSS builds to fail. For now,
download from a mirror which seems to be up.

If this becomes a frequent issue with this repository/others, we can consider a
different solution.

Also, not sure how lfs pointer edit was missed by previous commit, added here.

Subject: [PATCH 0500/1987] getdeps: dynamic dependency munging

Summary:
This diff adds a `fixup-dyn-deps` subcommand that is intended to
aid in packaging on multiple platforms.

Its purpose is to copy a set of executable object files from the getdeps
installation directories and place them into an installation staging
area that will then be used to create some kind of package (rpm, tarball etc.).

The dynamic dependencies of the executables are determined and also copied
into the destination area, and the important part: the execute is rewritten
such that it will load the deps out of an alternate installation prefix.

The implementation of this command draws on similar scripts in use for
the watchman and eden packaging on windows and macos.  This diff adds
linux support using the `patchelf` utility.

Subject: [PATCH 0517/1987] improve the code that searches for dumpbin.exe

Summary:
Fix dyndeps.py to find dumpbin.exe in more situations.

Previously the code looked for dumpbin.exe under Visual Studio directories
named either `BuildTools` or `Community`.  On a system with an MSVC 2017
Professional install it is instead located under a directory named
`Professional`.  This updates the glob to allow any directory name here.

 expression for thrift include directories

Summary:
Fix an error about source directories being included in the include
path in add_thrift_cpp2_library. I don't know why this was failing for
fb303 and not for other projects, but adding a generation expression
appears to fix the issue.

Subject: [PATCH 0531/1987] Add IWYU pragmas to unconventional private headers

Summary:
Typically, in fbcode, if a header is private to another header, we use the
`-inl.h` extension, which is useful for e.g. automated code refactoring.

For some cases that don't follow this convention, add some IWYU pragmas to
indicate the actual owning header.

Subject: [PATCH 0533/1987] cache results of path_search()

Summary:
getdeps currently ends up calling `path_search()` repeatedly searching for
various C/C++ compilers in $PATH.  It ends up doing this multiple times for
each dependency as it computes the project hashes.  This updates the
`path_search()` function to cache its results so that we don't keep performing
the same searches on the file system over and over again.

Subject: [PATCH 0535/1987] update CMakeBuilder to raise an exception if we
 cannot find CMake

Summary:
If `path_search()` returns that CMake is not available, raise an Exception and
fail the build.  This makes the failure somewhat easier to to identify.
Without this the code would continue and would try to invoke `subprocess` with
a value of `None` in the command argument list.  This error is slightly harder
to debug, since it isn't clear which command argument or environment variable
is not a string.

Subject: [PATCH 0541/1987] fix handling of common arguments

Summary:
getdeps allowed common arguments to be specified either before or after
the subcommand name.  However, the arguments were only actually honored
if they were specified on the command line after the subcommand name.
Specifying any of these arguments before the subcommand would simply be
ignored, and the default value would be used.  This happened since the
subcommand argument's default value overwrote the value specified by the
user from the main command parser.

This fixes the behavior by using `argparse.SUPPRESS` so that argparse
won't set the value at all if it was not specified.  This allows the
value from the main parser to be used correctly if the argument was not
seen by the subcommand parser.

Subject: [PATCH 0545/1987] Fix tests with Python 2.7

Summary:
Some people want to use getdeps with Python 2.7. This looks easy to do, so take a step toward Python 2.7 support by fixing getdeps' tests when run with Python 2.7.

For Python 3, this diff should not change behavior.

This diff should address https://github.com/facebook/bistro/issues/35.

Subject: [PATCH 0550/1987] Fix flake8 with Python 2.7

Summary:
flake8 (in Python 2.7 mode) complains that `typing` is mentioned in type annotations but is not defined:

```
fbcode_builder/getdeps/buildopts.py:251:21: F821 undefined name 'typing'
    subst_mapping,  # type: typing.Mapping[str, str]
                    ^
fbcode_builder/getdeps/buildopts.py:253:5: F821 undefined name 'typing'
    # type: (...) -> typing.Optional[str]
    ^
2     F821 undefined name 'typing'
2
```

Import `typing` explicitly to silence this warning.

Because `typing` may be unavailable, import it conditionally. (Because it's only referenced in comments, failing to import `typing` should have no effect at run time.)

Subject: [PATCH 0556/1987] Fix gmock handling in rsocket opensource build

Summary:
Simply linking `GMOCK_LIBS` into a binary was not telling CMake that the binary depends on `gmock` being built. So, let's add that dependency explicitly.

This wasn't breaking in production because we typically build with `-j 4`, and `gmock` was getting built before the first dependent binary would attempt to link.

Also, since `rsocket` bundles its own `gmock`, it is just a waste of time to compile a system-level gmock. It's not a real dependency.

NB: The change in `fbcode_builder.py` is needed because now that `rsocket` no longer depends on anything on Github, driver programs that were unconditionally setting `projects_dir` started to fail to build `rsocket`.

Summary:
Check that all variable names are valid when loading manifest files.
This ensures that getdeps.py will error out if someone makes a typo in a
variable name, rather than treating it as never equal to anything.

Subject: [PATCH 0565/1987] add a ManifestContext and ContextGenerator class

Summary:
Add a ContextGenerator class so that we actually use the correct per-project
context when loading projects and computing dependencies.

Previously commands like `build` and `test` would change the contexts for each
project as they iterated through and performed the build.  However, they did
not do this when first loading the projects.  This could cause them to use
different context values when loading dependencies than when performing the
build.  For instance, this could cause issues if a project depends on
`googletest` only when testing is enabled, as the code previously did not set
the "test" parameter when evaluating dependencies.

Subject: [PATCH 0566/1987] use the correct project-specific context when
 computing hashes

Summary:
Update `BuildOpts.compute_dirs()` to use the correct project-specific manifest
context when computing project hashes.  Previously it was incorrectly using
the initial project's context when evaluating all dependencies.  This would
result in some projects potentially seeing the wrong values for variables that
may change from project to project (like `test`).

Subject: [PATCH 0567/1987] add a new ManifestLoader class

Summary:
Add a new ManifestLoader class to handle loading manifests and computing
dependencies.

For now the main thing this class does is maintain the `manifest_by_name`
mapping.  In subsequent diffs we should be able to move some additional logic
into this class, which will help clean up the code and eliminate some redudant
work.  In particular, we can have this class cache project hashes, which will
avoid re-computing hashes over and over again for the same projects as we do
in many cases today.  We should also be able to save and re-use some of the
project dependency ordering computation in some cases as well.

Subject: [PATCH 0568/1987] add a create_fetcher() method to ManifestLoader

Summary:
The ManifestLoader contains all of the state needed to create a fetcher
object, so define a helper method on this object to create a fetcher.

Subject: [PATCH 0569/1987] move project hash computation to ManifestLoader

Summary:
Move code that computes project hashes to ManifestLoader.  ManifestLoader is
the only class that has all of the information necessary to compute the
project hashes correctly.  The ManifestLoader object can also cache previously
computed hashes, so that we don't have to keep computing hashes for projects
over and over again.  Previously the `BuildOptions.compute_dirs()` function
would end up re-computing hashes for all dependencies each time it was called.

Subject: [PATCH 0570/1987] have CMakeBuilder emit a script to allow invoking
 CMake manually

Summary:
While developing on a project it is often convenient to be able to invoke its
build manually, rather than always needing to re-run `getdeps.py`.  This
updates the CMakeBuilder to also emit a script that can be used to manually
run CMake outside of `getdeps.py`.

The CMakeBuilder is the only builder that this really matters for right now,
as pretty much all of the projects where we do first-party development use
CMake for their build system.

 (#891)

Summary:
The build of RSocket fails in this Ubuntu 18.04 Docker environment.
The reason is the fall through switch statements.

```
/home/rsocket-cpp/rsocket/tck-test/MarbleProcessor.cpp:95:33: warning: this statement may fall through [-Wimplicit-fallthrough=]
         subscriber.onError(std::runtime_error("Marble Error"));
                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/rsocket-cpp/rsocket/tck-test/MarbleProcessor.cpp:96:7: note: here
       case '|':
       ^~~~

         ~~~~~~~~~~~~~~~~~~~~~^~
/home/rsocket-cpp/rsocket/tck-test/MarbleProcessor.cpp:99:7: note: here
       default: {
```

As long as the marble_ has more items and more messages are expected from the subscriber,
it will continue publishing to the subscriber.

Subject: [PATCH 0585/1987] getdeps: make sure ManifestLoader never reloads
 manifests

Summary:
In response to review feedback for D16477400 and D16477401, update
`ManifestLoader.load_all_manifests()` to only update its data for projects
that have not previously been loaded.  This helps ensure that code using a
single `ManifestLoader` object cannot have two in-memory `Manifest` objects
for the same project, and that existing data (such as project hashes) can't be
invalidated if a manifest is later loaded from updated on-disk data.

Subject: [PATCH 0591/1987] getdeps: fix handling of the --host-type command
 line flag

Summary:
Fix the BuildOptions class to correctly honor the `host_type` parameter that
it was constructed with when constructing the manifest evaluation context.
I accidentally broke this behavior in D16477396, and incorrectly had this code
path default to using the current host system rather than the value passed in
from the command line.

Subject: [PATCH 0597/1987] getdeps: consolidate code for project subcommands

Summary:
Most of the getdeps subcommands operate on a single project, and some of the
argument parsing and initial logic to load the project is largely the same.
This consolidates that logic into a base class so that we can share this code
across subcommands, instead of repeating it.

This also unifies the behavior so that by default all commands enable tests on
the specified project, and disable test on dependent projects.  Making sure
all commands use the same behavior here is important as whether are not tests
are enabled can affect the project configuration, and therefore affect its
getdeps hash.

Subject: [PATCH 0598/1987] getdeps: fix a crash if the project_hashes
 directory does not exist

Summary:
This makes getdeps.py no longer crash if used in the folly repository.
Folly does not depend on any other Facebook projects, so it does not
include a `build/deps` directory.

Subject: [PATCH 0599/1987] getdeps: allow overriding project source, build,
 and install directories

Summary:
Add arguments to getdeps.py to allow overriding the source, build, and install
directories a per-project basis.  The arguments take the form `[PROJECT:]PATH`
If the `PROJECT` portion is omitted, it defaults to the current project being
built.

In particular this makes it possible to specify `--src-dir .` to tell
getdeps.py to find the project sources from the current directory rather than

Subject: [PATCH 0600/1987] getdeps: honor INSTALL_DIR correctly in the
 generated run_cmake.py script

Summary:
This cleans up how the `CMAKE_ENV` and `CMAKE_DEFINE_ARGS` variables are
written in the generated `run_cmake.py` script that we emit for CMake-based
projects.

We now emit each entry in these variables on separate lines, just to improve
readability.  (Both of these variables tend to have a number of entries and
are very long if emitted on a single line.)

This also replaces the `-DCMAKE_INSTALL_PREFIX` entry in `CMAKE_DEFINE_ARGS`
to have it correctly honor the `INSTALL_DIR` variable defined in
`run_cmake.py`.  This makes `run_cmake.py` still do the right thing if someone
manually edits it to change the `INSTALL_DIR` value.

Subject: [PATCH 0608/1987] fbcode_builder: CMake functions for building
 standalone python programs

Summary:
Add some CMake functions for building standalone executables from Python
source files.  This generates executables similar to PEX
(https://github.com/pantsbuild/pex).

In the future this could potentially be leveraged to directly build XAR files
(https://github.com/facebookincubator/xar).

The main advantages of these functions is that they allow easily defining
"libraries" of python files, and their dependencies, which can then be used
and packaged as part of multiple different standalone executables.

+#
+# Helper function for parsing arguments to a CMake function.
+#
+# This function is very similar to CMake's built-in cmake_parse_arguments()
+# function, with some improvements:
+# - This function correctly handles empty arguments.  (cmake_parse_arguments()
+#   ignores empty arguments.)
+# - If a multi-value argument is specified more than once, the subsequent
+#   arguments are appended to the original list rather than replacing it.  e.g.
+#   if "SOURCES" is a multi-value argument, and the argument list contains
+#   "SOURCES a b c SOURCES x y z" then the resulting value for SOURCES will be
+#   "a;b;c;x;y;z" rather than "x;y;z"
+# - This function errors out by default on unrecognized arguments.  You can
+#   pass in an extra "ALLOW_UNPARSED_ARGS" argument to make it behave like
+#   cmake_parse_arguments(), and return the unparsed arguments in a
+#   <prefix>_UNPARSED_ARGUMENTS variable instead.
+#
+# It does look like cmake_parse_arguments() handled empty arguments correctly
+# from CMake 3.0 through 3.3, but it seems like this was probably broken when
+# it was turned into a built-in function in CMake 3.4.  Here is discussion and
+# patches that fixed this behavior prior to CMake 3.0:
+# https://cmake.org/pipermail/cmake-developers/2013-November/020607.html
+#
+# The one downside to this function over the built-in cmake_parse_arguments()
+# is that I don't think we can achieve the PARSE_ARGV behavior in a non-builtin
+# function, so we can't properly handle arguments that contain ";".  CMake will
+# treat the ";" characters as list element separators, and treat it as multiple
+# separate arguments.

Subject: [PATCH 0613/1987] getdeps: fixup testpilot new test recording

Summary:
In the Facebook infrastructure the testpilot runner talks
to a service to determine whether a given test should be run locally.

The remote service was returning an error for some tests because they
didn't have enough configuration specified.

This diff associates some configuration with the tests based on the
host type and makes things happier.

Subject: [PATCH 0624/1987] fbcode_builder: update current commit for iproute2

Summary:
The manifest file for iproute2 previously listed the commit to check out as
7ca63aef7d1b0c808da0040c6b366ef7a61f38c1.  However, this is not a commit, but
a tag object that refers to commit 92a0236a3cdf3438000834121b7ea8a09f1f52b1.

This caused getdeps to think that iproute2 was always out-of-date, even when
it was already on the correct commit, since it was comparing current commit ID
against the tag ID.

This updates the manifest to refer to the commit ID instead of the tag ID.

Subject: [PATCH 0625/1987] fbcode_builder: update ThriftCppLibrary to use
 fb_cmake_parse_args()

Summary:
Change ThriftCppLibrary to use `fb_cmake_parse_args()`

This code doesn't really care much about handling empty arguments, so we could
use the standard `cmake_parse_arguments()` function here instead of
`fb_cmake_parse_args()`.  However, it is slightly more convenient that
`fb_cmake_parse_args()` automatically errors out on unhandled arguments, so
that we don't have to check for this ourselves.

Subject: [PATCH 0627/1987] fbcode_builder: ThriftCppLibrary: the output
 depends on the thrift templates

Summary:
Update ThriftCppLibrary.cmake to record that the output depends on the thrift
`cpp2` template files.  The `THRIFT_TEMPLATE_FILES` variable was defined in
D16062657 but doesn't appear to be used anywhere.  This uses it, and also
updates it to only match the C++ template files.

Summary:
Fix the fbzmq pathmap listed in its manifest file to match the path map
actually used by ShipIt.  The fact that this was broken was why internal
getdeps builds did not detect that D16577367 broke the build.

Summary:
The external Travis CI builds for fbzmq are still using the older
fbcode_builder spec (as opposed to the newer getdeps manifest file).

D16577367 moved the CMakeLists.txt file to the top-level directory, but the
fbzmq spec file was still looking for it in the fbzmq subdirectory.

Subject: [PATCH 0633/1987] fbcode_builder: support installing thrift generated
 header files

Summary:
Update add_thrift_cpp2_library() to add a PUBLIC_HEADER property to the
generated library target, so that the generated headers can be installed using
an `install()` call.  Also add a `HEADER_INSTALL_DIR` property which indicates
the directory they should be installed into.  A `INCLUDE_DIR` argument was
added to customize the include installation path, should anyone care to do so.

This also removes code that was previously incorrectly installing the
generated headers into the source tree.

Subject: [PATCH 0638/1987] use facebook::fb303 instead of common::stats where
 possible

Summary:
Most stat code in fbcode was moved in to open source under
fbcode/fb303. The only exception that we use internally is the
MonotonicCounter class. This diff moves all of our stats code to use
the open source headers and updates cmake files to pull in the open
source fb303.

Subject: [PATCH 0644/1987] fbcode_builder: cmake: propagate thrift include
 dependencies correctly

Summary:
Update `add_thrift_cpp2_library()` to pass in the correct `-I` flags when
invoking the thrift compiler so that it can find all of the other thrift files
that this library depends on.

D16062657 was a previous attempt to do this, but suffered from a few problems:
- It required all dependencies to be defined before
  `add_thrift_cpp2_library()` was called.  This requires users to carefully
  order their CMake files and subdirectory include ordering.
- It only handled one level of dependencies, and did not propagate include
  paths for deeper dependencies.
- It set the include path for dependencies to the source directory path where
  the dependency was originally built, rather than the directory where the
  thrift file for that dependency would be installed.

This change does require CMake 3.8+.  Previous versions of CMake do not
support using generator expressions to generate multiple arguments for a
custom command.

This just strips off a trailing '/' from the `INSTALL_DIR` property that we
set on python targets, to avoid having double-slashes in the paths that we use
during installation.  This shouldn't really have any material difference other
than cleaning up the paths that get printed during the installation phase.

Subject: [PATCH 0651/1987] fbcode_builder: fix install_fb_python_library() to
 work with old CMake versions

Summary:
Update install_fb_python_library() to work with CMake versions older than 3.7.

Previously the code used a generator expression in the directory argument
supplied to `install(DIRECTORY)`.  Support for generators in this parameter
was only added in CMake 3.5, but it was buggy and did not correctly handle
absolute paths until 3.7.

This updates the code to avoid using a generator expression.  This does
require that the corresponding `add_fb_python_library()` statement appear
before the `install_fb_python_library()` statement, but this seems like a
pretty reasonable restriction.

Subject: [PATCH 0654/1987] fbcode_builder: rename add_thrift_cpp2_library() to
 add_fbthrift_cpp_library()

Summary:
Rename the `ThriftCppLibrary.cmake` file to `FBThriftCppLibrary.cmake`, and
also rename `add_thrift_cpp2_library()` to `add_fbthrift_cpp_library()`.

Explicitly calling this `fbthrift` helps clearly distinguish that this is
intended for use with fbthrift (https://github.com/facebook/fbthrift/), as
opposed to Apache thrift.

 # Code of Conduct
 
-Facebook has adopted a Code of Conduct that we expect project participants to adhere to.
-Please read the [full text](https://code.fb.com/codeofconduct/)
-so that you can understand what actions will and will not be tolerated.
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to make participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies within all project spaces, and it also applies when
+an individual is representing the project or its community in public spaces.
+Examples of representing a project or community include using an official
+project e-mail address, posting via an official social media account, or acting
+as an appointed representative at an online or offline event. Representation of
+a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at <opensource-conduct@fb.com>. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html
+
+[homepage]: https://www.contributor-covenant.org
+
+For answers to common questions about this code of conduct, see
+https://www.contributor-covenant.org/faq

Subject: [PATCH 0664/1987] fbzmq: disable build on darwin and windows

Summary:
boost.fiber is not available on macos and is required by fbzmq,
so disable the build on darwin.

In D17128935 I tried to make libzmq build with cmake to build
on windows, but there's a problem with its cmake and it fails
to configure.

So let's just nop out the build for !linux for now.

Subject: [PATCH 0675/1987] getdeps: assign test owner in continuous runs

Summary:
Feed the first-party oncall data through to the testpilot
invocation.  This will set the owner of the test in continuous runs.

The oncall is passed through via the sandcastle module, which means
that you will have to manually pass it through for local testing
(see test plan), but it should automatically get picked up when
sandcastle schedules the `test` step of the job.

Subject: [PATCH 0684/1987] getdeps: add build cache abstraction

Summary:
This diff adds a small abstraction that allows for uploading
and downloading from an artifact cache.

We try to download from this cache at build time, but will only
try to populate it for continuous builds--those are built from
code that has been reviewed and landed on master.  This restriction
helps to avoid thrashing the cache with works in progress and
results in a slightly more trustworthy state of the cache contents.

In addition to this, we choose only to cache third party projects.
The rationale is that our first party projects move too quickly to
be worth caching, especially since the cache granularity is for
the whole project rather than just changed elements of a given
project.

In a later diff I will introduce some implementations of the
cache class that work with eg: Travis or Circle CI caching.

Subject: [PATCH 0686/1987] getdeps: allow aliasing sources for
 add_fb_python_executable

Summary:
* Fix a minor issue with `add_fb_python_executable` where it would
  emit `--main` even if `MAIN_MODULE` had not been specified
* Introduce the ability to rename python sources in the manifest so
  that they have a different install path.
* Note that this changes the DEPENDS parameters to reference abs_sources;
  previously these were using relative paths to the sources pulled directly
  from the SOURCES arguments, but since those can now contain aliasing
  operations we need to pre-process the list.  I switched to abs_sources
  because that was already being maintained.  If for some reason the
  DEPENDS list needs to be relative paths, this will need to be adjusted.

Subject: [PATCH 0688/1987] getdeps: build all available boost libraries

Summary:
This should make it easier to eg: enable fbzmq on macos at a later
time, and also makes things more explicit about what is being built, and
importantly, by listing these in the manifest ensures that we have a
hash change if we change this list; we wouldn't trigger such a change
if the list were encoded solely in builder.py

Subject: [PATCH 0698/1987] fbcode_builder: update FBPythonBinary.cmake to work
 on Windows

Summary:
On Windows we have to explicitly invoke `make_fbpy_archive.py` with python.
Therefore use CMake's built-in `FindPythonInterp` module to find the python
executable and use that when invoking `make_fbpy_archive.py`

This is slightly complicated by the effort required to find python with older
versions of CMake.  We ideally still want to support versions of CMake back to
at least 3.8, which means we need to still support finding Python with the
older `FindPythonInterp.cmake` module

Subject: [PATCH 0706/1987] getdeps: fix openssl dep for libevent on macos

Summary:
while testing https://github.com/facebook/watchman/pull/743 on macOS
I noticed that the libevent build failed to find openssl.

openssl is special on macos because apple do not ship the headers.
We already build and depend on openssl for the folly manifest on
macos, so this is really just adding a missing edge.

Subject: [PATCH 0707/1987] getdeps: restructure bison+flex dependencies

Summary:
We've been squeaking by with assuming that flex is installed already
on posix systems, but that isn't the case on the github actions default
configuration.

Adjust the bison recipe: on windows it deploys both flex and bison.  We use the
same source for both flex and bison but install flex to a separate install
prefix to make it easier to consume the flex dependency distinct from the bison
dependency.

The latest flex release segfaults during compilation on linux unless we
force -DGNU_SOURCE, so the manifest does that on linux.

Subject: [PATCH 0708/1987] getdeps: prefer MSVC over gcc when building on
 GitHub Actions CI

Summary:
while testing https://github.com/facebook/watchman/pull/743 I
noticed that the cmake builds were picking up the installed mingw GCC
compiler rather than the MSVC compiler.  That would be fine except that
boost is built with MSVC and its generated libraries cannot be subsequently
found by a cmake gcc build that uses FindBoost.

This commit forces cmake to pick cl.exe rather than gcc.  This is probably
fine to do unconditionally on windows, but since I've only observed this
particular problem with GitHub Actions I'm keeping it constrained to that
environment for now.

Subject: [PATCH 0709/1987] getdeps: teach builder how to find vs 2019

Summary:
GitHub Actions CI `windows-latest` environment has only VS 2019
installed, so we need to expand our logic to be able to locate it.

Note that Boost 1.69 doesn't know how to locate VS 2019 so we are effectively
tied to VS 2017 at the moment; the search order in this diff reflects that.

(That means that we can't target `windows-latest` on GitHub Actions, but that
is really a concern for a later diff in this stack)

Subject: [PATCH 0710/1987] Let's try a github action to build things (#743)

Summary:
This commit adds a getdeps command that is able to generate
a workflow file for the GitHub Actions CI environment.

The workflow file could be expressed more simply using the matrix
syntax and with three steps (checkout, build, test), but I chose to
break out the steps for each of the dependencies because the UX
while waiting on the build is much nicer that way: the steps show
during and live log tailing for the section of the build that is
underway.  If they were all lumped into a single build step then
the logs from the boost section of the build dominate and make
the github UI work very hard.

Pull Request resolved: https://github.com/facebook/watchman/pull/743

Test Plan:
https://github.com/facebook/watchman/pull/743 successfully
executes the github actions CI flow.

```
$ opensource/fbcode_builder/getdeps.py generate-github-actions --output-file watchman/.github/workflows/main.yml watchman
```

 absolute paths

Summary:
This commit teaches fixup-dyn-deps how to generate correct
absolute paths in the context of the ultimate install path (specified
via the `--final-install-prefix` option)

Absolute paths are desirable if you have, for example, an executable
that you wish to install with the setuid bit set.

Subject: [PATCH 0717/1987] fix the thrift CMake rules to add dependencies on
 the thrift compiler

Summary:
Update the thrift C++ and Python CMake rules to indicate that the output also
depends on the thrift compiler itself.

Previously the C++ rule indicated that the output depended on the thrift
template files, which caught most cases when the thrift compiler was updated,
but wasn't fully correct.  The thrift templates were also removed and baked
into the thrift compiler binary in D16356056.

Subject: [PATCH 0728/1987] add a builder that can re-package python wheel
 files

Summary:
Add a new builder that can extract Python wheel files, and re-package them
for consumption by our add_fb_python_library() and add_fb_python_executable()
CMake functions.  This is useful for dependencies on packages from PyPI.

At the moment this code only handles architecture-independent pure-Python
packages.  It shouldn't be too hard to extend this to handle more complex
wheels, but for now I only need to use it for some pure-Python wheels and so I
haven't tested with more complex wheel files.

This also includes two new manifests for python-six and python-toml that take
use this new builder.

Subject: [PATCH 0729/1987] the libraries in thrift/lib/py depend on six

Summary:
The libraries in thrift/lib/py support both Python 2 and Python 3, and rely on
the Python six module for some of this compatibility support.

Update the getdeps manifest for fbthrift to indicate this dependency, and
update fbthrift's CMakeLists.txt file to find and reference python-six
properly.  This will ensure that the python-six code is built into any python
executable that uses the thrift/lib/py libraries.

Subject: [PATCH 0738/1987] fix calculation of whether a project is cachable

Summary:
Never cache first-party projects that use ShipIt.  Previously the code checked
the `shipit_fbcode_builder` property, which controlled whether or not
the `fbcode_builder` sources should be included in the project's ShipIt
mapping.  This setting is enabled for most but not all projects that use
ShipIt.

This resulted in projects that use ShipIt but that do not include the fbcode
builder sources being incorrectly cached.  This caused getdeps.py to not
run the SimpleShipitTransformerFetcher properly when their sources changed.

Subject: [PATCH 0739/1987] improve run_cmake.py on Windows

Summary:
Update the generated `run_cmake.py` script to use `subprocess.run()` instead
of `os.execve()`.  The `os.execve()` call doesn't really do what we want on
Windows: this causes the script to exit while CMake is still running,
resulting in confusing output.  During the build step it also did not work
correctly with `vcvarsall.bat`, and using `subprocess` also solves this.

Subject: [PATCH 0740/1987] fbcode_builder: implement automatic project
 detection from the current repo

Summary:
This updates fbcode_builder to try and automatically detect the current
repository's project name by looking for a `.projectid` file in the repository
root.  If the project name can be detected:
- The current repository will automatically be used as the source directory
  for this project (instead of fetching the sources into the scratch
  directory).
- If an explicit project name was not specified on the command line, the
  current project will be built by default.

This also changes the repository detection logic to use the current working
directory, rather than the directory where the fbcode_builder code lives.
This will allow this logic to work even if we move fbcode_builder into its own
repository in the future, and have projects depend on it using git submodules.
This does mean that callers need to invoke fbcode_builder.py from inside the
repository.

Subject: [PATCH 0746/1987] adding openr to this framework

Summary:
this adds `oss-openr-linux-getdeps` to diffs affecting files under openr. With soma going away and the old fbcode_builder job disabled, this will give us the signal we need to keep the cmake build healthy.

[Some Info on Getdeps](https://our.intern.facebook.com/intern/wiki/Test_your_Open_Source_build_with_getdeps.py/)

Michael, this change may require you to bump up some of the dependent libraries and build them with cmake if not already. The main changes to the cmake script are around using package configs instead of `find_library`

Also, for those with more CMake experience: since there are some big changes in the `CmakeLists`, feel free to pour on more suggestions on how I could make it better and more aligned with other facebook OSS

Subject: [PATCH 0770/1987] getdeps: fixup-dyn-deps: use patchelf from our
 manifest on linux

Summary:
On linux we use `patchelf` to manipulate dynamic deps but it
isn't guaranteed to be installed everywhere.  We have a manifest file
that describes how to build it, but so far nothing has told getdeps
that it should build it.

This diff updates the ELF dep munging code to literally run
`getdeps.py build patchelf` and then use that patchelf binary to
manipulate the object files.

Subject: [PATCH 0772/1987] getdeps: ensure that INST/lib/*.dll are found in
 PATH on windows

Summary:
We were troubleshooting an issue with the eden tests on windows
where the boost dlls where not being found during gtest discovery.

When we compute the environment, we were only including INST/bin in the
PATH on windows.  On Windows, the dlls are searched for in the PATH, and
since boost installs those into its `lib` dir we were missing those.

This diff causes `lib` dirs to get added to PATH on windows in the same
manner that we would add them to `LD_LIBRARY_PATH` on linux.

Subject: [PATCH 0775/1987] watchman: getdeps: Capture artifacts from Github
 Actions CI builds (#750)

Summary:
This diff teaches the generated Github Actions configuration to copy the
executable outputs from the leaf project into an artifacts dir, and then capture
the artifacts in the build.

This page has details on the artifacts mechanism used by Github Actions:
https://github.com/actions/upload-artifact

This page has the "Artifacts" link on the RHS where an example of the artifacts
can be downloaded:
https://github.com/facebook/watchman/pull/750/checks?check_run_id=244088199

Here's the actual download:
https://github.com/facebook/watchman/suites/247296465/artifacts/74686

And here's what the inside of that zip file contains for the watchman build:

Subject: [PATCH 0777/1987] getdeps: add libcurl and make Eden use libcurl
 instead of system curl

Summary:
We are seeing random segment fault originating from OpenSSL on macOS when
Mononoke fetching is enabled.

The cause is that on macOS we are actually linking against libcurl shipped with
the system instead of ours. That copy of libcurl is linked with macOS's
libcrypto instead of the one we compiles during Eden's build, and it seems that
version of libcrypto does not provide concurrency safety.

The solution is to build curl on macOS and make sure it is linked to our
OpenSSL that has the concurrency callbacks registered.

Subject: [PATCH 0784/1987] Revert / fix up D17158685

Summary:
Proxygen no longer uses `fbcode_builder` to run its tests, so whatever the purpose of D17158685, these `fbcode_builder` configs no longer affect Proxygen, and can be reverted to their original state.

Since the general design pattern for `fbcode_builder` has been to link everything as `.so`s, let's return to this (which helps fix Bistro's build).

Also, let's not waste time building & linking tests for libraries that are not the library under test. That is:
 - Before: The Bistro build also builds tests for wangle, proxygen, etc. This is a result of some accidental changes in D17158685.
 - After: We explicitly don't build test for any of the 4 dependencies here. This is OK because each project also has its own `fbcode_builder_config.py`, which **does** build tests.

This latter part should result in a build-time reduction.

Subject: [PATCH 0800/1987] Fix exception slicing issue

Summary:
StateMachine::close() takes an exception_wrapper, so passing an exception in can potentially slice it.
Constructing an exception_wrapper in the first place avoids this, and keeps the assertion happy.

Subject: [PATCH 0806/1987] watchman: pass version info down to watchman build
 via environment

Summary:
This diff allows passing a watchman version number override
via the environment as well as via the cmake `WATCHMAN_VERSION_OVERRIDE`
option.

To help invalidate the build I've added a new section to the manifest
files that allows listing out additional env vars that the project
hashes should be sensitive to.  The effect of this is that we'll
re-run the cmake configure step if the listed env vars are changed.

Subject: [PATCH 0818/1987] getdeps: memoize eden prefetched dirs

Summary:
currently, the implementation of `eden prefetch` calls into
a mercurial function that is overly eager in making network connections,
which results in what should be a fast NOP second prefetch call taking
more time than is desirable.

This diff adds a little cache to avoid repeatedly calling prefetch
for the same directory more than once for the life of the getdeps
process.

Given the usage pattern of getdeps it is OK that we don't provide
a way to invalidate this cache.

Subject: [PATCH 0822/1987] getdeps: [EASY] pass yarn offline mirror location
 for fbsource builds

Summary:
Our CI environment cannot directly connect to the internet,
and even if it could, doing so is undesirable to fetch javascript deps.
We maintain an offline mirror of packages used by the build(s) so that
we don't have to go out to the internet.

When running in fbsource, configure the environment to use that offline
mirror.

Subject: [PATCH 0840/1987] Fix rsocket exception handling crash

Constructing an exception_wrapper in the first place avoids this, and keeps the assertion happy.

Subject: [PATCH 0860/1987] getdeps: fix node/yarn detection for watchman
 builds

Summary:
When we detect that we are building out of the fbsource
monorepo internal to FB, pre-set some environment variables to help
projects detect our internally pinned versions of node and yarn.

Previously, the detection logic was deciding that the `yarn` shell
script was the executable to invoke, but since that is a bash script
it would fail to spawn.

Subject: [PATCH 0862/1987] Replace Folly Format with fmt in logger to reduce
 binary size

Summary:
Now that fmt is available in Folly builds (D14813810), use it to reduce binary code size in Folly Logger. This is done by moving most of the formatting logic behind the type-erased `vformat` API. Previously it was instantiated for all combinations of formatting argument types used in calls to `FB_LOGF` and `XLOGF` in a program.

The effect of this change can be illustrated by looking at symbol sizes as given by `nm -S -td` for the following test function:

```
void test_log() {
  FB_LOGF(logger, WARN, "num events: {:06d}, duration: {:6.3f}", 1234, 5.6789);
}
```
compiled in `opt` mode.

`nm` before:

```
0000000004236736 0000000000000231 T test_log()
0000000004236992 0000000000001002 W std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > folly::LogStreamProcessor::formatLogString<int, double>(folly::Range<char const*>, int const&, double const&)
```

`nm` after:

```
0000000004237536 0000000000000231 T test_log()
0000000004237792 0000000000000251 W std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > folly::LogStreamProcessor::formatLogString<int, double>(folly::Range<char const*>, int const&, double const&)
0000000004238048 0000000000000740 W folly::LogStreamProcessor::vformatLogString[abi:cxx11](folly::Range<char const*>, fmt::v5::format_args, bool&)
```

Before we had one 1002 byte instantiation of `formatLogString<int, double>`. With this change it was reduced 4x to 251 bytes and non-template function `vformatLogString` was added which is shared among all logging calls. The size of `test_log` remained unchanged. There are even bigger savings from Folly Formatter instantiations which are no longer needed, e.g.

```
0000000004238032 0000000000001363 W _ZNK5folly13BaseFormatterINS_9FormatterILb0EJRKiRKdEEELb0EJS3_S5_EEclIZNKS7_8appendToINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEEENSt9enable_ifIXsr12IsSomeStringIT_EE5valueEvE4typeERSH_EUlNS_5RangeIPKcEEE_EEvSK_
```

So in total this change results in ~5x per-call/instantiation binary size. It is possible to reduce binary size even further but it is not done in the current diff to keep it manageable.

In addition to binary size improvements, switching to fmt will potentially

* allow catching errors in format strings at compile time,
* simplify future migration to C++20 [`std::format`](http://eel.is/c++draft/format).

Subject: [PATCH 0865/1987] getdeps: update FBPythonBinary.cmake to generate
 executable files on Windows

Summary:
On Windows, compile a small C executable to prepend to the zip file, to allow
the resulting executable files to be run directly on Windows, without needing
to explicitly invoke the Python interpreter to run the output file.

Subject: [PATCH 0871/1987] getdeps: update eden dependencies

Summary:
Include tools/lfs in the shipit path map for now, since it is needed to
download vendored Rust crates on internal builds.  Also correctly indicate
that the fb-mercurial* dependencies also apply only to internal builds.

Subject: [PATCH 0881/1987] Make it possible to compile openr through
 CMakeLists.txt

Summary:
This diff fixes `CMakeLists.txt` to enable building `openr` tests using CMake:
1. It adds `add_openr_test` CMake function that adds executable target, registers it as test, links it with bunch of libraries like GTest and GMock, etc...
2. There is no `openr/tests/OpenrModuleTestBase.cpp` anywhere in the source tree, so this commit replaces it with `openr/common/Flags.cpp`.

Subject: [PATCH 0893/1987] Install wheel and cython on fbcode_builder venv
 environments

Summary:
This is an update to the fbcode_builder codebase to allow setting up the python virtualenv with python dependencies installed. I've included wheel and cython (with a pinned version to 0.28.6 which is the only version that works with thriftpy3 at the moment, due to https://github.com/cython/cython/issues/2985) as standard packages since these are required by some of our top-level dependencies (folly and thrift)

As far as I know, there are no other projects that use PYTHON_VENV at the moment except LogDevice so the impact should be minimal.

 git-lfs

Summary:
OpenBCM libraries are stored with git LFS. As a result, fetcher fetches LFS pointers and not the contents. Use git-lfs to pull the real contents before copying to install dir using NoopBuilder.
In future, if more builders require git-lfs, we would consider installing
git-lfs as part of the sandcastle infra as against repeating similar
 logic for each builder that requires git-lfs.

Subject: [PATCH 0900/1987] getdeps: rocksdb: don't enable -Werror

Summary:
It's impossible for a consumer of a released version of
rocksdb to do anything about this except not use it, and this particular
version of rocksdb ships with a number of shadow warnings.

Disable warning to error promotion.

Subject: [PATCH 0903/1987] getdeps: add an install_fb_python_executable()
 function to the CMake utilities

Summary:
Add a `install_fb_python_executable()` function to `FBPythonBinary.cmake` for
helping to install python executables generated with
`add_fb_python_executable()`.  This primarily helps by automatically looking
up the correct output file to install from the generated targets.

Subject: [PATCH 0914/1987] write build output to a log file

Summary:
Update the getdeps builders to save all command output to a log file in the
build directory.  This makes it easier to go back after the fact and look at
the config options selected by the build run.

Subject: [PATCH 0924/1987] Remove -Werror

Summary:
Remove `-Werror` to fix the following build error:

```
rsocket-cpp/yarpl/../yarpl/Refcounted.h:45:23: warning: moving a local object in a return statement prevents copy elision [-Wpessimizing-move]
   45 |   return std::move(old);
      |                       ^
```

In general it's a bad idea to use `-Werror` anywhere except CI.

Subject: [PATCH 0964/1987] OpenNSA: Don't use opennsl, switch to bcm-only API

Summary:
With the release of OpenNSA (https://github.com/Broadcom-Network-Switching-Software/OpenNSA), we can stop using opennsal altogether!

This diff was created using following steps:

cd fboss/agent
find . ! -path "*\/oss*" -type f \( ! -iname "*TARGETS*" \) -exec sed -i -e 's/opennsl_spl_//g' {} \;
find . ! -path "*\/oss*" -type f \( ! -iname "*TARGETS*" \) -exec sed -i -e 's/opennsl/bcm/g' {} \;
find . ! -path "*\/oss*" -type f \( ! -iname "*TARGETS*" \) -exec sed -i -e 's/OPENNSL/BCM/g' {} \;
find . ! -path "*\/oss*" -type f \( ! -iname "*TARGETS*" \) -exec sed -i -e 's/OpenNSL/Bcm/g' {} \; # for symbols like snmpBcmTransmittedPkts2048to4095Octets

Furthermore:

- In all TARGETS under fboss/agent replace wrapped_opennsl_symbols with wrapped_bcm_symbols.
- hg mv agent/facebook/test/OpenNSLInterface.h agent/facebook/test/BcmInterface.h
- BcmEgress.cpp remove operator== overload for opennsl API altogether, and remove operator== BCM API version from inside unnamed namespace, and put it in fboss namespace.
- BcmCinter.h and BcmCinter.cpp now have some duplicate definitions as opennsl_ got renamed to bcm_. Delete one of the definitions "as appropriate".
- Similarly, remove duplicate definitions in FakeSdk.h and FakeSdk.cpp
- Similarly, remove duplicate definitions in SdkTracer.cpp (remove definitions calling CALL_WRAPPERS_RV_NO_CINTER). And lastly, remove CALL_WRAPPERS_RV_NO_CINTER itself.
- arc lint
- Remove OpennslCompatTests.cpp
- Fix ./agent/hw/bcm/tests/facebook/BcmEgressTest.cpp to have #include
  "fboss/agent/facebook/test/MockOpenNSL.h" instead of MockBcm.h

TODO:
- This patch retains the directory structure (facebook/ subdirectory), which will be fixed in subsequent patches.
- Remove opennsl references from TARGETS file, additional cleanup etc.
- Remove all oss directories...

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
This is an interim solution that unblocks failing FBOSS OSS builds.

Broadcom's OpenNSA is available on github and contains large precompiled
libraries. For large files (> 100Mb), github uses git-lfs.

git clones to OpenNSA started failing yesterday with:

Error downloading object: lib/x86-64/libopennsa.a (7f21d94): Smudge error:
Error downloading lib/x86-64/libopennsa.a
(7f21d941ac32ccae38adb05b3386be739bdccd502a878364d386e7a5cb172f35): batch
response: This repository is over its data quota. Account responsible for LFS
bandwidth should purchase more data packs to restore access.

Github documents (refer:
https://help.github.com/en/github/managing-large-files/about-storage-and-bandwidth-usage)
“When you download a file tracked with Git LFS, the total file size is counted
against the repository owner’s bandwidth limit”. It appears we are hitting that
limit.

Thus, github is not a good choice here. Even if we create a 'github release
tarball', the tarball continues to carry lfs files and thus downloading those
counts towards the quota (which is limited).

Broadcom paid some amount to bump up the quota, but it is matter of time before
we hit it esp given that these builds run on-diff.

A better solution is to download a tarball (that contains real files, not lfs),
and then allow Facebook lfs to cache it.

While github does not support that, it seems bitbucket does.

Thus, we forked OpenNSA from github into a bitbucket repo and this patch
modifies the manifest to download a tarball from bitbucket that will be cached.

Broadcom is working on a cleaner solution but this will keep our FBOSS OSS build
clean in the interim.

Subject: [PATCH 0976/1987] opensource/fbcode_builder/getdeps.py: support cargo
 dependencies in cargo builds

Summary:
With this change the getdeps' CargoBuilder will support depencies between cargo builds.

The way how it works is documented in the code and required few assumptions about how a cargo project has to be defined in order to support this.

This change also adds the "mononoke" manifest and few Cargo.toml files to the mononoke project to prove that this new feature works.

Subject: [PATCH 0981/1987] Update the CheckAtomic CMake module to check for
 __atomic_fetch_add_4 instead of __atomic_is_lock_free

Summary:
When building with clang, the build fails with:

```
-- Looking for __atomic_is_lock_free in atomic
-- Looking for __atomic_is_lock_free in atomic - not found
CMake Error at cmake/CheckAtomic.cmake:90 (message):
  Host compiler appears to require libatomic, but cannot find it.
Call Stack (most recent call first):
  CMakeLists.txt:75 (include)
```

And the error is:

```
/usr/share/cmake-3.10/Modules/CheckFunctionExists.c:7:3: error: conflicting types for '__atomic_is_lock_free'
  CHECK_FUNCTION_EXISTS(void);
  ^
<command line>:1:31: note: expanded from here
#define CHECK_FUNCTION_EXISTS __atomic_is_lock_free
                              ^
/usr/share/cmake-3.10/Modules/CheckFunctionExists.c:7:3: note: '__atomic_is_lock_free' is a builtin with type 'int (unsigned long, const volatile void *)'
<command line>:1:31: note: expanded from here
#define CHECK_FUNCTION_EXISTS __atomic_is_lock_free
                              ^
/usr/share/cmake-3.10/Modules/CheckFunctionExists.c:17:25: error: too few arguments to function call, expected 2, have 0
  CHECK_FUNCTION_EXISTS();
  ~~~~~~~~~~~~~~~~~~~~~ ^
```

LLVM's CheckAtomic (https://fburl.com/bk14shjt) uses `__atomic_fetch_add_4` so I'm modifying the configs to use it as well to check for the existence of the library.

Subject: [PATCH 0995/1987] move AsyncGenerator->Flowable shim into yarpl

Subject: [PATCH 0998/1987] Fix std::move warning in yarpl

Summary:
The std::move prevents copy elision (NRVO), and gcc9 is warning about
it. Every compiler we use will do NRVO here, and in c++17 and later
the compiler is required to use the move constructor if it (for
whatever reason) fails to elide the copy.

Subject: [PATCH 1014/1987] Migrate scribe thrift client from SemiStream to
 ClientBufferedStream

Summary: Thrift is deprecating SemiStream in favor of new ClientBufferedStream / AsyncGenerator. This is converted back to Flowable using a custom shim that respects external flow control.

Subject: [PATCH 1015/1987] migrate rsocket tests to ServerStream

Summary:
Most of the tests still work
A few are inapplicable and are deleted
Others highlight differences in behavior between the stream types and their interaction with rsocket. These are disabled and a followup task is created to pin down these differences.
We should not block this migration based on these differences. We will likely delete or rewrite many of these tesets when we finish deleting rsocket.

Subject: [PATCH 1038/1987] enable lz4 in the getdeps build of rocksdb

Summary:
The Buck build of RocksDB supports LZ4, so if an Eden instance's
object cache ends up compressed with LZ4 compression, the opensource
getdeps build cannot open it. Enable LZ4 in the open source getdeps
build of rocksdb.

Subject: [PATCH 1060/1987] Use BaseService for thrift-handler from oss-fb303

Summary:
This diff adds fb303 dependency to Open/R. fb303 is FB's open-sourced project
which provides basic infrastructure for thrift service e.g. base functions,
counters supports etc.

Using this in Open/R will allow both internal & external users leverage counters
via thrift APIs

Subject: [PATCH 1066/1987] Remove dependency on fbzmq::ResourceMonitor & sigar

Summary:
Replace the methods to get CPU and memory usage statistics:
- For the memory: use `VmRSS` of `/proc/[pid]/status`: http://man7.org/linux/man-pages/man5/proc.5.html
- For the CPU%: calculate the process is occupied how much percentage of the CPU time, use `getrusage()`: http://man7.org/linux/man-pages/man2/getrusage.2.html
   - Implemented like the sigar: https://our.intern.facebook.com/intern/diffusion/FBS/browse/master/third-party/sigar/src/sigar.c?commit=4f945812675131ea64cb3d143350b1414f34a351&lines=111-169
  - Formula:
    - CPU% = `process used time` during the period / `time period` * 100
    -  `time period` = current query timestamp - last query timestamp
    - `process used time` = current `process total time` - last query `process total time`
    - `process total time` = CPU time used in user mode + CPU time used in system mode // get from the API `ru_utime` and `ru_stime`

Remove the `fbzmq::ResourceMonitor` and `sigar`:
- Change and rename the UT
  - `ResourceMonitorTest.cpp` -> `SystemMetricsTest.cpp`
  - `ResourceMonitor` -> `SystemMetricsTest` in `openr/tests/OpenrSystemTest.cpp`
- Remove `ResourceMonitor` code and dependency for `Watchdog` and `ZmqMonitor`
- Remove `sigar` dependency used in building

 windows

Summary:
Ideally we'd be using mkscratch, but this still isn't shipped
to our Windows systems.

Pick a path that is more friendly to our corp windows environment by default.

Subject: [PATCH 1093/1987] revisionstore: add a LFS remote store

Summary:
This enables fetching blobs from the LFS server. For now, this is limited to
fetching them, but the protocol specify ways to also upload. That second part
will matter for commit cloud and when pushing code to the server.

One caveat to this code is that the LFS server is not mocked in tests, and thus
requests are done directly to the server. I chose very small blobs to limit the
disruption to the server, by setting a test specific user-agent, we should be
able to monitor traffic due to tests and potentially rate limit it.

Summary:
OpenNSA has prebuilt SDK but kernel modules have to be built from sources. Add
a utility script to build and extend packaging script.

In future, we can consider folding this build into fbcode_builder itself.

If you have built the `eden/scm` subdirectory with `make local` in your
repository it will have left a bunch of build output artifacts in the source
tree.  Update the getdeps shipit path map for eden to explicitly exclude many
of these build artifacts.

In particular:
- Exclude `eden/scm/build/` since this directory can contains a lot of files.
- Exclude all `*.pyc` files since there may be a reasonable number of these.
- Exclude several Cargo-related files since these will cause problems when
  trying to build Rust code.

Ensure that we are referencing python3 in the paths
that we generate for the github actions workflows, and remove
some shebangs that influence how our internal linters process

Subject: [PATCH 1108/1987] getdeps: fix git configuration on windows

Summary:
The GH actions defaults for git prevent it from being able
to checkout the fbthrift repo due the length of the java related
files in the fbthrift repo.

This commit tells git to use long filenames and allows the checkout
to succeed.

Subject: [PATCH 1109/1987] getdeps: fixup the dyndeps fixed up by fixup
 dyndeps

Summary:
On linux we didn't account for the `--final-install-prefix` argument
which meant that the binaries would always be rewritten to be relative to
the destdir.

This commit fixes that.

Refs: https://github.com/facebook/watchman/issues/760

(this doesn't deal with the compiled in statedir being in the scratch path though)

Subject: [PATCH 1121/1987] getdeps: fixup python3 usage on GitHub Actions CI

Summary:
My recent change to ensure that we were using python3 to launch everything failed on windows: the GH actions environment has `python.exe` in the path and it is python version 3.  There is no such thing as `python3` in that environment, although there is a `python2`.

Subject: [PATCH 1125/1987] getdeps: allow setting per-project install prefix
 for DESTDIR installs

Summary:
We have a global `--install-prefix` argument that can be used to set
the prefix for all projects, but that is only suitable if you are running with
sufficient privileges to install each of the deps to that location during the
build.  Cmake dependency resolution won't work from the build directory in that
situation; it can only see the final installed location and it will error out
if those files are not present, or link against the currently installed version
instead of the version we just built; not great!

This commit adds a project specific `--project-install-prefix` that can be used
on just the leaf project in a set of deps.  That sidesteps the dependency
concern because only the last stage is built in that mode.  This option
can technically be applied to an arbitrary set of projects, but in light
of the above, in practice it only makes sense to use it for the final
cmake project.  Only the CMakeBuilder respects this option.

In the watchman repo, this commit adjusts the autogen.sh script to allow
specifying the installation prefix; it defaults to `/usr/local` as you
might expect.

Subject: [PATCH 1127/1987] watchman: teach watchman to talk to EdenFS on
 Windows

Summary:
This still requires support from EdenFS in order to do much
of use, but it takes us a step closer:

* Pull in cpptoml when building with Eden support
* On Windows, when we locate the `.eden` directory, load and parse
  the config file in order to determine the socket path
* If the EdenView constructor throws, treat it as a terminal error
  so that we don't fallback to the regular filesystem watcher.
  This is important because current EdenFS builds don't implement
  the journal thrift API endpoint yet.

Subject: [PATCH 1129/1987] emit a script to use for running commands from the
 build directory

Summary:
On Windows the build artifacts cannot be easily run directly from the build
output directory without installing them.  The `$PATH` environment variable
needs to be set correctly so that the runtime library dependencies can be
found.

This updates the builder code to emit a `run.ps1` wrapper script in the build
output directory that sets `$PATH` to support running build artifacts directly
from the build directory.

Additionally, this updates the CMake-specific builder to set properly when
running the tests with `ctest`.

Summary:
I was testing vs2019 vs vs2017 and realized that
we weren't reconfiguring when the toolchain was changed;
this resolves that.

Subject: [PATCH 1136/1987] Fix bug in optimizing module loader for coverage
 collection

Summary:
In coverage collection mode a special module loader is prepended to
`sys.meta_path`. In very specific conditions this module loader can end up
returning a loader pointing to a _completely wrong module_. When importing
symbols from the wrong module errors occur.

The conditions to trigger the bug are:

- running in coverage collection mode, enabling the custom loader
- the test binary is a zip (e.g. par_style=fastzip)
- having a module name where the end part matches the name of a builtin Python
  module

When these conditions were met, the special loader would return the builtin
Python module instead of the expected module. E.g. when loading a module like
`myapp.somemod.platform` in a zip style binary.

The custom loader first calls `imp.find_module()` to find the module it wants
to return a wrapped loader for. This fails for modules included in the test
binary, because the builtin `imp` module can not load from zips. This was the
trigger leading to the call to the buggy code.

When the initial call to `imp.find_module()` failed, the custom loader would
try a second call, asking the internal loader to this time try any path on
`sys.path`. For most module names this call would also fail, making the custom
loader return `None`, after which Python tries other loaders on `sys.path`.
However, when the final part of the module that was asked to load matches the
name of a Python builtin module, then the second call to the `imp` module would
succeed, returning a loader for the builtin module. E.g. `platform` when asking
for `myapp.somemod.platform`.

This diff fixes the issue by removing the broken second call to the internal
loader. This will never have worked, we just have not triggered or noticed
triggering the wrong loading before.

Subject: [PATCH 1146/1987] Rename collectXSemiFuture to collectX

Summary:
Migration from Future-returning executor-erasing collectX forms to
SemiFuture-returning forms, that are less risky in particular with coroutines.

Earlier changes added collectXSemiFuture and collectXUnsafe as a migration
path. We then migrated collectX callsites to collectXSemiFuture or
collectXUnsafe and switched the implementation of collectX to the SemiFuture
form.

This diff renames uses of collectXSemiFuture to collectX, as the two are
identical.

Subject: [PATCH 1151/1987] getdeps: export fbsource commit date into
 environment

Summary:
This diff extracts the fbsource commit hash and the date of that
commit and maintains that in place of just the commit hash that
we were previously extracting.

This data is exported into the environment that we pass on to
builders so that it is available if they choose to use it.

In a follow on diff I'll use this to default a version number
in the watchman project.

Subject: [PATCH 1156/1987] getdeps: make several improvements to the eden
 manifest

Summary:
- Indicate that the EDEN_VERSION_OVERRIDE environment variable affects the
  build.
- Exclude eden/config.py from the shipit  path map, as this file is
  auto-generated in open source builds.
- Include pexpect as a dependency, as this is needed for some of the
  integration tests.

Subject: [PATCH 1168/1987] getdeps: partially educate getdeps about EdenFS on
 Windows

Summary:
I noticed that copytree was taking forever and realized
that it wasn't issuing a prefetch call so I started looking in here;
this commit teaches getdeps how to recognize and EdenFS repo on
Windows but skips calling prefetch on Windows.

Currently the prefetch implementation triggers some very slow
processing in mercurial that is slower to start than just
enumerating the files in the opensource build.

It turned out that my original problem was just that my credentials
had expired and we weren't surfacing that error on Windows yet.

Subject: [PATCH 1172/1987] fix how folly and its downstream projects find
 boost

Summary:
Folly links explicitly links against boost statically on Windows.  However,
many downstream projects that use folly independently performed their own
discovery of boost and normally used the default option of linking against it
dynamically.  This resulted in boost being listed twice on the link line on
Windows for some downstream projects: both its static libraries and dynamic
libraries would be present.  This ends up causing linking failures due to
duplicate definitions.

This updates folly's installed CMake file to correctly call
`find_dependency(Boost)` so that downstream projects don't need to perform
their own independent discovery.  This ensures that all downstream projects
use a consistent method of linking against Boost.  I updated many downstream
projects to remove their explicit separate discovery, and rely only on this
behavior from folly.

I also added a configuration setting to allow explicitly selecting whether to
link against boost statically at folly configure time.

Subject: [PATCH 1175/1987] getdeps: allow satisfying deps from system packages

Summary:
From the outset, we wanted to be sure that getdeps was able
to source and build the dependencies so that we knew that we'd have
a repeatable build.  This came at the cost of build times: having
to build boost on each CI run is a bit of a chore.

This commit adds three new elements to the manifest files:

* `rpms` - a list of RPM names that are all required to be present
  in order to consider the dependency satisfied
* `debs` - like `rpms` above, but scoped to debian package names
* `preinstalled.env` - a list of environment variables that if they
  are all set and non-empty will satisfy the dependency.

A new `--allow-system-packages` option to getdeps enables the new
logic that looks for system packages; it is off by default, but
enabled in the generated GitHub Actions workflows.

A new `install-system-deps` subcommand is provided that will attempt
to install the system packages needed to satisfy the build.  This
typically needs to be run via sudo and is thus broken out separately
from the main getdeps build flow.

I made a pass over the manifest files and added package names that
satisfy the build on ubuntu-18 and fedora-31.

shri-khare: I renamed the `Python3.7.6` manifest to just `python` as
part of this change; the version of python that it pulls in through
the normal build is the same and I believe that an equal or newer
version of python3 is available in the GH actions builder.

The `preinstalled.env` is used only by the boost manifest: it references
the name of an environment variable that is set by the github
windows hosts and that points to a pre-built and pre-installed
copy of boost.  Since there is no package manager that we can
easily query for this sort of thing, probing from the environment
seems like a reasonable and fast way to check for this.  We
may need to evolve this over time to become more feature rich,
but this seems like a good starting point.

This commit has the potential to save 20 minutes of build time
from each public CI build just due to the boost dependency alone!

Subject: [PATCH 1176/1987] GH actions: fixup boost windows environment (#1359)

Summary:
The environment changed since I tested  D20740410 and now it appears
that we'll need to re-export a versioned variable in order for cmake
to detect boost on the GH actions hosts.
Pull Request resolved: https://github.com/facebook/folly/pull/1359

Test Plan:
the GH actions status of this diff.

The workflow was updated via:

```
python3 build/fbcode_builder/getdeps.py generate-github-actions folly --output-file .github/workflows/main.yml
```

Subject: [PATCH 1177/1987] fb_py_win_main.c: fix File Not Found errors on
 windows

Summary:
This commit resolves an issue with our zipapp executables
on Windows that meant that the only reliable way to start them was
to use the fully path to the executable.

The root cause is that the __wargv array is produced by parsing the
process command line into an array, and if you ran `watchman-wait -h`
__wargv[0] would have `watchman-wait` rather than the fully qualified
path to the executable that the zipapp plumbing requires.

The fix is to ask the system for the fully qualified path and ensure that
that gets set as both argv[0] AND argv[1].

Subject: [PATCH 1178/1987] getdeps: split monolithic GH actions CI spec up
 (#1360)

Summary:
Rather than have a single main.yml file containing all off the different
builds, split that up so that we have one file per build environment
(linux, mac, windows).

This has a couple of advantages:

* It is quicker to see the status of just one of the platforms
* Artifact collection for one platform is not blocked pending completion
  of the builds for all systems
* It's a little easier to understand what is happening for a single platform

To support having multiple files I've changed the output-file option to
be an output-dir.

I've included the rm of main.yml in this commit.  Once this gets
imported back to the FB internal system I'll amend in an update to
the helper script that updates all of our opensource builds and run
and amend that.
Pull Request resolved: https://github.com/facebook/folly/pull/1360

Test Plan:
the GH action status on this PR should show three different
actions running, one for each platform.

I updated and ran
`fbcode/opensource/fbcode_builder/getdeps/facebook/update-all-github-actions.sh`
to regenerate all the actions files for FB.

Subject: [PATCH 1180/1987] getdeps: fix artifact generation (#808)

Summary:
The mismatched project output settings were causing
the dyndeps fixup to fail to find any objects and thus none of
the artifacts are populated for posix platforms.

Pull Request resolved: https://github.com/facebook/watchman/pull/808

Test Plan:
The PR published artifacts to:

* https://github.com/facebook/watchman/actions/runs/91617994
* https://github.com/facebook/watchman/actions/runs/91617996
* https://github.com/facebook/watchman/actions/runs/91617997

Subject: [PATCH 1181/1987] getdeps: GH actions: strip artifacts before
 capturing them (#809)

Summary:
On Linux the debug info sections in projects downstream from folly and
thrift are huge due to a lot of C++ template usage.

We build in RelWithDebInfo mode as that is most useful when debugging
locally and because the build times are long, but most casual consumers
of the binaries via GH actions really don't care about debug info,
and this should save ~180MB of size in (for example) the watchman
executables.

Pull Request resolved: https://github.com/facebook/watchman/pull/809
Refs: https://github.com/facebook/watchman/issues/804

Test Plan:
Review the artifact size on the linux build in this PR (see
https://github.com/facebook/watchman/actions/runs/91688952) and confirm that it
is a bit smaller than 180MB; now under 3 MB.

Subject: [PATCH 1184/1987] getdeps: improve how run_cmake.py invokes ctest

Summary:
Update the generated `run_cmake.py` script to tell ctest to print the test
output on failure.  Also pass in a `-j` flag to run tests in parallel by
default.

These flags are already passed in by default when running `getdeps.py test`;
this simply updates this developer utility script to do the same.

Subject: [PATCH 1188/1987] eden: enable rocksdb in the windows build

Summary:
In the initial stages of the windows port we had
problems building rocksdb on windows, so we disabled it.

These days we're able to build it and detect it--we even
require it in the cmake code, but hadn't gotten around
to telling the rest of the code that we can use it.

This commit re-enables it in the build but leaves sqlite
as the default engine until we're able to perform some
benchmarking.

Rocksdb itself has some build issues on Windows; it doesn't
use cmake to locate dependencies, so even though we built
snappy it doesn't know how to find it without modifying the
source:
https://github.com/facebook/rocksdb/blob/master/thirdparty.inc#L4

For that reason, we disable the use of Snappy in the Windows build.
However, in the version of rocksdb that we were using, it would
default to trying to use Snappy even though it wasn't compiled in
and throw an exception.

I've upgraded to a newer version of rocksdb that will simply not
use compression if no compression was enabled at build time.

Given that we mostly store relatively small objects, I'm assuming
that the lack of compression is fine for now.

Subject: [PATCH 1192/1987] getdeps: indicate that folly depends on lz4

Summary:
Update the manifest file for folly to indicate a dependency on lz4.
folly does not require lz4 be available, but it will use it if it is found at
configure time.

getdeps is unfortunately not strict about providing projects only with the
dependencies that they require at build time.  This causes it to sometimes
make lz4 available to folly (if you are also building another project that
requires lz4), and sometimes not.  This ends up causing changes in
folly-config.h depending on which projects you are building, forcing all of
the folly sources to be recompiled.

In the future we perhaps should update getdeps to consistently only pass in
include directories for dependencies actually listed in the manifest file.
However, specifying that folly depends on lz4 also works to mitigate this
particular issue for now, and it is also generally desirable to build folly
with lz4 support.

Subject: [PATCH 1193/1987] getdeps: avoid blowing away too much data when
 invalidating the CMake cache

Summary:
Previously getdeps would remove the entire top-level `CMakeFiles` directory
from the build output when it wanted to invalidate the CMake cache.  This
directory is used to keep all of the compiled object files for any libraries
or executables defined in the top-level CMakeLists.txt file.  Blowing away
this directory forces all of these sources to be re-compiled, even if this was
not necessary.  This is particularly problematic for folly, which compiles all
of its source files via rules in the top-level CMakeLists.txt target file.

I did have the code still blow away the CMake error and output logs in this
directory: in the past I have seen situations where CMake would not update
these files on new CMake runs if they already existed.

 reconfigure

Summary:
Only run cmake reconfigure for .cmake, .cmake.in and CMakeLists.txt
files changes.

Previously we would reconfigure for any change to a file with a path that
matched `cmake` which could result in false positives in cases where
you may be iterating on .py or .c files in shared cmake directories.

This also reclassifies non-cmake files under fbcode_builder/CMake as source
files so that we run cmake for those; previously they would cause a
reconfigure and build, now they just cause a build.

Subject: [PATCH 1196/1987] getdeps: improve build invalidation for
 dependencies

Summary:
We didn't do a great job of recognizing that we'd need to
build a project when one of its dependencies had changed: we relied
chiefly on the dependency hash for this and could fail to handle
changes in individual source files.

This commit helps to improve this situation by checking to see if
any installed files in the dependencies of a manifest are newer than
the most recent built time of a given manifest.  If so, we'll trigger
a build.  We try to be reasonably smart about deciding when to trigger
a cmake reconfigure if it looks like cmake files in the deps have
been changed.

Subject: [PATCH 1197/1987] getdeps: fix an fbsource invalidation problem

Summary:
When the commit hash changed in fbsource, we would correctly decide
that we'd need to rebuild first-party projects but we would incorrectly skip
running the fetcher.update method.  This would mean that we'd not perform the
shipit run and that our shipit tree would diverge from the source tree.

This commit resolves this by performing the fetcher.update but ignoring
the source update status in this case.

for projects for which we pulled the build out of cache, because there
is no source to update in that case.

This commit adjusts the logic so that we write out a marker file
to indicate that we installed a build from cache and to look for
that file being present to gate the new update logic.

Subject: [PATCH 1211/1987] mononoke/fbcode_builder: bring back mononoke
 manifests for getdeps build

Summary:
The breakage has been fixed, so bring back the manifest, but only the Linux one, because the Mac version is failing due to another issue.

Also to make it easier to debug issues on GitHub Actions separate out the dependencies build from Mononoke and rust-shed builds.

Subject: [PATCH 1216/1987] getdeps: silence inherits via dominance warnings

Summary:
Previously, the Windows build was litered with warnings of the form (typo included):

  warning C4250: 'C1': inherits 'C2::C2::method' via dominance
  note: see declaration of 'C2::method'

Microsoft doesn't offer any recommendation, and the internet suggest that the
right `using` should silence it. That's unfortunately not the case, adding:
  using C2::method
In `C1` doesn't do anything, and the compiler still complains :(.

Since the warning appears to be non-actionable, and looks more like a
"notice" than a warning, let's just silence it.

Subject: [PATCH 1220/1987] getdeps: add filtering of tests

Summary:
For large projects, with lots of tests, running all the tests can take a lot
of time, but for quick development iteration, only a subset of the tests may
be needed to run.

On non-Windows platforms, this can be easily achieved by manually executing
the individual tests binaries and use the builtin filtering mechanism of that
test binary to achieve the goal. On Windows, this can quickly become
impossible as DLLs might not be available, and the right PATH would need to
be manually specified by hand to execute the tests binaries[0].

To solve this, let's simply provide a unified way of running specific tests
by passing in a regexp. Both testpilot and CTest do support regex to execute
specific tests. My understanding is that cargo doesn't yet allows regex, but
will in the future.

[0]: And a missing DLLs would produce no output when executed from
     PowerShell, which makes this very confusing.

 substitutions

Summary:
We use drive letter substitutions to workaround Windows
filename length limitations.  On my personal Windows system running
python 3.8.2 realpath inside an ssh session manages to resolve to
the full filename which causes the boost build to fail.

Avoid that!

Subject: [PATCH 1249/1987] Update fmt version to 6.2.1

Summary:
Update fmt version to 6.2.1 for better compatibility with the version used in fbcode. Among other things this fixes fbthrift build failure on Travis:

```
/home/fbthrift/thrift/lib/cpp2/async/RocketClientChannel.cpp:70:67:   required from here
/home/install/include/fmt/core.h:492:3: error: static assertion failed: don't know how to format the type, include fmt/ostream.h if it provides an operator<< that should be used
```
which is caused by trying to format an enum class without a formatter - only supported as of 6.0.

Subject: [PATCH 1250/1987] Specify error handler for text encoding in logging
 functions.

Summary: Currently output from build command is decoded with "surrogateescape" error handler, but when writing to log files/stdout we don't specify error handlers to be also "surrogateescape" according to https://docs.python.org/3/library/codecs.html#error-handlers, which could cause exception when there's surrogate characters logged in message.

Subject: [PATCH 1254/1987] Fix shell builders (#50)

Summary:
In 0ae204a978c11ddefafd81bd319a078239a44c1c the 'projects_dir' option
became a required constructor argument since it is called within the
constructor. However, it has not been adjusted in the subclasses that
used to set the option after instantiation. This commit fixes the
'shell_builder' and the 'debian_system_builder'.
Pull Request resolved: https://github.com/facebook/openr/pull/50

Test Plan:
1. Go to build directory: `cd build`
2. Run the `shell_builder` & `debian_system_builder`:
    - `python fbcode_builder/shell_builder.py`
    - `python debian_system_builder/debian_system_builder.py`

`shell_builder` output before:
```
Traceback (most recent call last):
  File "fbcode_builder/shell_builder.py", line 102, in <module>
    builder = ShellFBCodeBuilder()
  File "/home/butjar/tu/ma/openr/build/fbcode_builder/fbcode_builder.py", line 93, in __init__
    self._github_dir = self.option('projects_dir')
  File "/home/butjar/tu/ma/openr/build/fbcode_builder/fbcode_builder.py", line 108, in option
    raise RuntimeError('Option {0} is required'.format(name))
RuntimeError: Option projects_dir is required
```

`shell_builder` output after:
```

Subject: [PATCH 1265/1987] re-enable lz4 compression for rocksdb on macOS and
 Linux

Summary:
I think LZ4 was disabled accidentally in our rocksdb getdeps build in
D21319896. Enable it again on macOS and Linux, because otherwise this
breaks people with EdenFS mounts containing LZ4-compressed proxy
hashes.

Subject: [PATCH 1269/1987] cargo_from_buck: add the patch section to Cargo
 workspace and allow workspace appending to existing manifest

Summary:
Two changes here:
1. The `[patch.crates-io]` section of `third-party/rust/Cargo.toml` is being now copied over to workspaces generated by autocargo for OSS and in the runtime generated Cargo.toml file for cargo-fbcode builds. Without that some projects could be buildable in Buck internally, but not externally on GitHub due to missing patches.
2. If a `[workspace]` Cargo.toml file is being generated and there is already a generated Cargo.toml file in the same directory then instead of overriding that file the `[workspace]` (and `[patch]`) sections are appended to that Cargo.toml file.

Subject: [PATCH 1277/1987] GitHub Actions: fix running out of space on Ubuntu
 build workflow (#23)

Summary:
As per https://github.com/actions/virtual-environments/issues/709 there started to be some issies with Ubuntu envs running out of space. This should fix it.

Also our Cargo builds use a lot of space, changing them to be non-incremental and removing debug symbols keeps the build fast, but greatly reduces the disk space usage leaving us enough space on GitHub Actions virtual machines.

Subject: [PATCH 1280/1987] fix encoding bug

Summary: This bug can be triggered when your computer name contains emoji. getdeps.py will fail to create this file due to Python attempts to write the file as cp1252 (Windows's default encoding)

Subject: [PATCH 1281/1987] fbcode_builder: getdeps: OpenNSA update source URL

Summary:
We had to fork OpenNSA and clone from it, see D19437386 for details.
Broadcom has now started hosting OpenNSA as a tarball.
Thus, we no longer need to maintain a fork (yay!)

This patch points opennsa manifest to fetch opennsa from this new location.

Subject: [PATCH 1285/1987] mononoke/configerator structs: change the OSS
 folder where configerator structs are saved

Summary:
Due to Thrift design of "include" statements in fbcode the thrift structures has to be contained in folders that are identical to the folder layout inside fbcode.

This diff changes the folder layout on Cargp.toml files and in fbcode_builder, there will be a next diff that changes this for ShipIt as well.

Subject: [PATCH 1294/1987] Fix OpenNSA 6.5.19 hash as Brcm modified the
 tarball

Summary:
Koray reported issue with OpenNSA while using build VM and observed that we
don't hit the issue on devserver thanks to downloading the lfs cached file.

The root cause:

Broadcom added License notice and uploaded new 6.5.19 with same name.
This changed the hash though - causing fbcode builder to complain.
Fix it by adjusting the hash.

See the first line in the recursive diff of before vs. after: P134467317

(the broken symlinks is an unrelated existing issue, which we have reported to
Broadcom).

Subject: [PATCH 1300/1987] make fb_py_win_main to dynamically find Python3.dll
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
In EdenFS's latest Windows package. We are seeing DLL import errors coming from `asyncio` as it requires a system native module `_overlapped.pyd`.

The underlying cause is because when we build EdenFS CLI on Sandcastle, we are linking with Python 3.6.2. The Python36.dll shipped with the EdenFS package is also coming from that version.

However, on Windows laptop. We have Python 3.6.3. Since we are not shipping the Python system libraries with us. It uses the libraries installed in the system, and it attempts to import the `_overlapped.pyd` located at `C:\Pythone36\DLLs\`. This version is compiled against Python 3.6.3, which is incompatible with the Python36.dll we are using.

----

To resolve this, we need either ship an embedded copy of Python along with EdenFS, or teach EdenFS to use the Python distribution installed in the system. This commit tweaks the executable we prepend to the archive created with zipapp to locate `Python3.dll` dynamically. This allows us to use the Python installed in the system so we can avoid the version mismatch issue.

With this setup, we can also be shipping an embedded Python version along with EdenFS, and the Python loader can look for that path. This is demonstrated with the relative DLL loading `..\python`.

In theory, we can have a package structure like this:

```
.
├── python
│   ├── ....
│   └── python3.dll
└── bin
    ├── ...
    ├── edenfsctl.exe
    └── edenfs.exe
```

Subject: [PATCH 1304/1987] eden/scm: provide getdeps.py way of building
 eden/scm on GitHub

Summary:
In order to do what the title says, this diff does:
1. Add the `eden/oss/.../third-party/rust/.../Cargo.toml` files. As mentioned in the previous diff, those are required by GitHub so that the third party dependencies that are local in fbsource are properly defined with a "git" dependency in order for Cargo to "link" crates properly.
2. Changes to `eden/scm/Makefile` to add build/install commands for getdeps to invoke. Those command knowing that they are called from withing getdeps context they link the dependencies brought by getdeps into their proper places that match their folder layout in fbsource. Those Makefile commands also pass a GETDEPS_BUILD env to the setup.py invocations so that it knows it is being called withing a getdeps build.
3. Changes to `eden/scm/setup.py` that add "thriftasset" that makes use of the getdeps.py provided "thrift" binary to build .py files out of thrift files.
4. Changes to `distutils_rust` to use the vendored crates dir provided by getdeps.
5. Changes to `getdeps/builder.py` and `getdeps/manifest.py` that enable more fine-grained configuratior of how Makefile builds are invoked.
6. Changes to `getdeps/buildopts.py` and `getdeps/manifest.py` to disable overriding PATH and pkgconfig env, so that "eden/scm" builds in getdeps using system libraries rather than getdeps-provided ones (NOTE: I've tried to use getdeps provided libraries, but the trickiest bit was that Rust links with Python, which is currently not providable by getdeps, so if you try to build everything the system provided Python libraries will collide with getdeps provided ones)
7. Added `opensource/fbcode_builder/manifests/eden_scm` for the getdeps build.

Subject: [PATCH 1307/1987] avoid using relative path in fb_py_win_main

Summary:
After some experimenting, it is a little awkward if we want to specify a relative path based on the executable location. We'd need to add a bunch of path calculations to make it right, and I don't think the added complexity is really worth the effort.

As a result, let's just remove the use of relative path, and if we ever want to ship a copy of Python distribution, we can place it under the same directory as the binary.

Subject: [PATCH 1315/1987] edenscm/hg: add GitHub Actions with CI for HG plus
 add fixes for getdeps (#25)

Summary:
Fixes include:
1. Passing "GETDEPS_BUILD_DIR" and "GETDEPS_INSTALL_DIR" env variable and using them in eden/scm/Makefile rather than assuming the source code is always in the same place regardless getdeps arguments (it isn't).
2. Added "fbthrift-source" and "fb303-source" to avoid unnecessary compilation (at least of fb303) and to put fbthrift and fb303 source code in an easy to locate place inside getdeps' "installed" folder.

Pull Request resolved: https://github.com/facebookexperimental/eden/pull/25

Test Plan: sandcastle, check oss-eden_scm-darwin-getdeps

Subject: [PATCH 1325/1987] fix boost macOS build with new Xcode

Summary:
When we build boost 1.69.0 with newer version of Xcode, it will fail with:

```
clang: error: unknown argument: '-fcoalesce-templates'
```

This commit fixes this build failure by telling boost's build system that we are building with clang on macOS.

Subject: [PATCH 1331/1987] add Mononoke integration tests CI (#26)

Summary:
This diff adds a minimal workflow for running integrations tests for Mononoke. Currently only one test is run and it fails.

This also splits the regular Mononoke CI into separate files for Linux and Mac to match the current style in Eden repo.
There are the "scopeguard::defer" fixes here that somehow escaped the CI tests.
Some tweaks have been made to "integration_runner_real.py" to make it runnable outside FB context.
Lastly the change from using "[[ -v ... ]" to "[[ -n "${...:-}" ]]; in "library.sh" was made because the former is not supported by the default Bash version preinstalled on modern MacOS.

Subject: [PATCH 1372/1987] runcmd: do not pipe stdout on a tty

Summary:
Redirecting stdout means that ninja/cmake won't act as if it's invoked
interactively, ie: it will buffer the output, show every single files being
compiled (instead of just a line or progress), etc. This results in a fairly
janky UX when getdeps is used on the command line. By not redirecting stdout,
we get immediate feedback about the tests being run, and the files being
compiled.

Subject: [PATCH 1384/1987] flush stdout before starting a command while
 interactive

Summary:
Now that the subprocess output is no longer piped, we can see a weird situation
where the command being run is displayed after the compilation step:

This is a bit awkward. Flushing stdout's buffer allows for the ordering to be
correct.

Subject: [PATCH 1397/1987] Add github action to auto-release TagIt tags

Summary:
This came from a [request from Fred Emmott](https://fb.workplace.com/groups/osssupport/permalink/4116491528399431/), but also is something we should do due to the GitHub UI redesign:

Nowadays on GitHub, tags are not shown in the sidebar (just the count) and instead GitHub Releases are prioritized and the most recent *release* is shown.

Secondly, the Source Code zip archives for tags/releases are created on-the-fly on GitHub. This can cause problems for downstream projects that need consistent content hashes of the archive for security/reproducability reasons. This action also creates its own archives (zip and tar.gz) and attaches them to the release.

Subject: [PATCH 1425/1987] update FindGflags.cmake to work on CentOS 8.x
 (#1409)

Summary:
Update FindGflags.cmake to work on recent CentOS and RedHat distributions.

On these distributions the CMake package configuration installed by the
gflags-devel RPM is slightly broken, and sets `gflags_INCLUDE_DIR` to a
directory that does not exist.  This happens because `/lib64` is symlinked to
`/usr/lib64`, and CMake ends up searching `/lib64` before `/usr/lib64` by
default when searching for packages.  Therefore it finds `gflags-config.cmake`
via the `/lib64` symlink.  However, `gflags-config.cmake` computes the include
directory relative to where its config file was found, and this relative path
computation only works when using the actual `/usr/lib64` path where it was
installed.  When found via `/lib64` it returns a bogus `//include` path that
does not exist.

This updates `FindGflags.cmake` to verify if the `gflags_INCLUDE_DIR` path
actually exists, and set it to a sane location instead.

This also updates the code to use the `gflags-shared` target that is exported
by the default gflags package configuration if it was only built as a shared
library.

Subject: [PATCH 1428/1987] update fbcode_builder README to document getdeps.py

Summary:
Update the `README.md` file in the fbcode_builder subdirectory to document the
current getdeps.py build system rather than the older fbcode_builder scripts
that required each project to keep their own python-based build files in their
project directory.

 # Easy builds for Facebook projects
 
-This is a Python 2.6+ library designed to simplify continuous-integration
-(and other builds) of Facebook projects.
+This directory contains tools designed to simplify continuous-integration
+(and other builds) of Facebook open source projects.  In particular, this helps
+manage builds for cross-project dependencies.
 
-For external Travis builds, the entry point is `travis_docker_build.sh`.
+The main entry point is the `getdeps.py` script.  This script has several
+subcommands, but the most notable is the `build` command.  This will download
+and build all dependencies for a project, and then build the project itself.
 
+## Deployment
 
-## Using Docker to reproduce a CI build
+This directory is copied literally into a number of different Facebook open
+source repositories.  Any change made to code in this directory will be
+automatically be replicated by our open source tooling into all GitHub hosted
+repositories that use `fbcode_builder`.  Typically this directory is copied
+into the open source repositories as `build/fbcode_builder/`.
 
-If you are debugging or enhancing a CI build, you will want to do so from
-host or virtual machine that can run a reasonably modern version of Docker:
 
-``` sh
-./make_docker_context.py --help  # See available options for OS & compiler
-# Tiny wrapper that starts a Travis-like build with compile caching:
-os_image=ubuntu:18.04 \
-  gcc_version=7 \
-  make_parallelism=2 \
-  travis_cache_dir=~/travis_ccache \
-    ./travis_docker_build.sh &> build_at_$(date +'%Y%m%d_%H%M%S').log
-```
+# Project Configuration Files
 
-**IMPORTANT**: Read `fbcode_builder/README.docker` before diving in!
+The `manifests` subdirectory contains configuration files for many different
+projects, describing how to build each project.  These files also list
+dependencies between projects, enabling `getdeps.py` to build all dependencies
+for a project before building the project itself.
 
-Setting `travis_cache_dir` turns on [ccache](https://ccache.samba.org/),
-saving a fresh copy of `ccache.tgz` after every build.  This will invalidate
-Docker's layer cache, foring it to rebuild starting right after OS package
-setup, but the builds will be fast because all the compiles will be cached.
-To iterate without invalidating the Docker layer cache, just `cd
-/tmp/docker-context-*` and interact with the `Dockerfile` normally.  Note
-that the `docker-context-*` dirs preserve a copy of `ccache.tgz` as they
-first used it.
 
+# Shared CMake utilities
 
-# What to read next
+Since this directory is copied into many Facebook open source repositories,
+it is also used to help share some CMake utility files across projects.  The
+`CMake/` subdirectory contains a number of `.cmake` files that are shared by
+the CMake-based build systems across several different projects.
 
-The *.py files are fairly well-documented. You might want to peruse them
-in this order:
- - shell_quoting.py
- - fbcode_builder.py
- - docker_builder.py
- - make_docker_context.py
 
-As far as runs on Travis go, the control flow is:
- - .travis.yml calls
- - travis_docker_build.sh calls
- - docker_build_with_ccache.sh
+# Older Build Scripts
 
-This library also has an (unpublished) component targeting Facebook's
-internal continuous-integration platform using the same build-step DSL.
-
-
-# Contributing
-
-Please follow the ambient style (or PEP-8), and keep the code Python 2.6
-compatible -- since `fbcode_builder`'s only dependency is Docker, we want to
-allow building projects on even fairly ancient base systems.   We also wish
-to be compatible with Python 3, and would appreciate it if you kept that
-in mind while making changes also.
+This directory also still contains a handful of older build scripts that
+pre-date the current `getdeps.py` build system.  Most of the other `.py` files
+in this top directory, apart from `getdeps.py` itself, are from this older
+build system.  This older system is only used by a few remaining projects, and
+new projects should generally use the newer `getdeps.py` script, by adding a
+new configuration file in the `manifests/` subdirectory.

Summary:
in getdeps we currently don't build and run the tests
There are a few issues:
  1. we need to also build tests for fizz, wangle, mvfst since proxygen tests include headers only exported if building tests in dependencies
  2. we use `ExternalProject_add` for gtest/gmock. but doesn't seem to be playing nicely with getdeps

Subject: [PATCH 1452/1987] eden/edenapi and mononoke integration tests: add
 edenapi/tools to getdeps and use them in tests (#51)

Summary:
Pull Request resolved: https://github.com/facebookexperimental/eden/pull/51

This diff extends capabilities of CargoBuilder in getdeps so that individual manifests can be build even without workspaces. Thanks to that a build for edenapi/tools can be made and its artifacts can be used in mononoke integration tests.

 OpenSSL (#12)

Summary:
Pull Request resolved: https://github.com/facebookexperimental/rust-shed/pull/12

The OpenSSL version on Mac doesn't work well with EdenSCM and Mononoke integration, just use the one from getdeps/brew.

Also remove the now redundant "DEVELOPER_DIR" since the modern XCode version works.

Subject: [PATCH 1465/1987] build zstd in static to avoid DLL dependency on
 Windows

Summary: It seems after updating zstd to 1.4.5. `Dllexport` for zstd.dll was not being picked up correctly. Instead of having zstd being a runtime dependency let's try statically link it to avoid the DLL issue.

Subject: [PATCH 1475/1987] Use a beta version of libbpf to unblock
 perf_buffer__buffer API

Summary: It turns out that perf_buffer API is only available in libbpf 0.2.0, which hasn't been released yet. To unblock katran, I grabbed the latest libbpf revision and created a temporary manifest. To avoid relying on this "beta" version libbpf on other projects only katran uses it. I'll make sure to remove it in favor of the official libbpf 0.2.0 once it's released.

Subject: [PATCH 1488/1987] mononoke/integration: create a Makefile to run
 tests as part of getdeps.py build (#67)

Summary:
Pull Request resolved: https://github.com/facebookexperimental/eden/pull/67

With this change it will be possible to build dependencies of and run integration tests using getdeps.py.

This is the first goal of Q4 as per https://fb.quip.com/v8YzAYNSYgot: "Get Open Source version of integration tests running on Legocastle".

Before this diff:
The OSS integration tests run now on GitHub by:
- Building some test dependencies with getdeps.py
- Building some test dependencies with homebrew/apt-get
- Running tests via python script

The OSS integration tests were not running on Sandcastle.

After this diff:
The OSS integration tests run on Github by:
- Building and executing tests via getdeps.py (execution of tests happens by getdeps.py calling Make calling python script)

The OSS integration tests run on Sandcastle using the same getdeps.py setup as Github.

Subject: [PATCH 1493/1987] rust/shed/hostname: rename hostname dependency to
 unbreak doctests (#15)

Summary:
Pull Request resolved: https://github.com/facebookexperimental/rust-shed/pull/15

With the update from rustc 1.44 to 1.47 the doctests started to break when building a crate that depends on a different crate of the same name, see this: https://github.com/rust-lang/cargo/issues/6819

This diff also removes the TravisCI build as it was broken and unused for some time.

Subject: [PATCH 1500/1987] FindGlog: Add support for 'glogd' Debug library
 (#1479)

Summary:
Glog v0.4.0 when configured with Debug build type adds a 'd' suffix to
the library file. This results in FindGlog.cmake failing to locate it.

Update FindGlog.cmake to use check for 'glogd', and use
select_library_configurations() to set GLOG_LIBRARY to the correct
found filename.

(Note: this has no effect if a non-Debug type is used.)

Subject: [PATCH 1506/1987] Keep interaction alive until streams and sinks are
 completed

Summary: Terminating an interaction signals to the server that it may clean up resources once outstanding requests are completed. Currently we wait for all handler methods to return before destroying the tile, but this is too narrow a definition of completed in the case of streams. Adds a pointer to both stream implementations to defer the releaseRef call until the stream has completed. This is easy to define for the generator; for the publisher we wait until the completeOrcancel callback has been called.

Subject: [PATCH 1520/1987] Fix discovery of `libsodium`

Summary:
By putting this in `fizz-config.cmake`, we can use depend on the `sodium` target without compromising our dependents ability to find the library.

Put the search module in the common location under `fbcode_builder/CMake` to let dependents use it.

Subject: [PATCH 1521/1987] Fix OSS build

Summary:
There are two separate changes here.

### Use `find_package`

The old setup of "let's manually enumerate and order the libraries that Bistro depends on" worked fine, except:
 - it was a bit brittle (requiring occasional patches as deps changed), and
 - it garnered a lot of feedback to the effect of "your build is weird, so it's probably broken because of that."

Now I expect to have fewer breaks and more plausible deniability :)

 More importantly, this should make it much easier to migrate to `getdeps.py`.

## Statically link `fmt`

After `fmt` was added as a `folly` dependency, and linked into Folly code used by Bistro, its tests would fail to run with this error: `test_sqlite_task_store: error while loading shared libraries: libfmt.so.6: cannot open shared object file: No such file or directory`.

Something was getting messed up in the dynamic linking, and it wasn't clear to me what -- the way that Bistro is linking its dependencies certainly seems sensible. Most likely one of the dependencies is incompatible with dynamic linking in a subtle way. I suspect Proxygen.

The `fmt.py` change in this diff addresses this problem by forcing static linking on the offending library.

Subject: [PATCH 1524/1987] getdeps: don't depend on git fetch depth any longer

Summary:
This commit takes advantage of git 2.5.0 being able to fetch a
requested revision rather than relying on the desired revision being within the
depth limited fetch.

This relies on having git 2.5.0 on the server which is true for all
of the projects we have manifests for; this shows zero matches:

```
$ rg repo_url opensource/fbcode_builder/manifests | grep -v github
```

We've had a couple of situations recently where folks have run into issues with
the commit rate in folly being higher than then fetch depth, so this should
address that.

Subject: [PATCH 1526/1987] rust-shed/futures_01_ext: rename futures_ext to
 futures_01_ext

Summary: As part of the effort to deprecate futures 0.1 in favor of 0.3 I want to create a new futures_ext crate that will contain some of the extensions that are applicable from the futures_01_ext. But first I need to reclame this crate name by renaming the old futures_ext crate. This will also make it easier to track which parts of codebase still use the old futures.

Subject: [PATCH 1537/1987] proxygen: fix shared libs build

Summary:
Right now proxygen hardcodes a static build when using cmake  and
ignores BUILD_SHARED_LIBS. Fix that, and enable PIE on the shared libs so they
can be linked properly

Closes: https://github.com/facebook/proxygen/issues/335

Subject: [PATCH 1550/1987] convert a path to valid glob syntax when
 prefetching

Summary:

is used for escaping. This caused problems on Windows, where we tried
to pass a backslash-delimited path into `eden prefetch --no-prefetch`.

Subject: [PATCH 1569/1987] GitHub Action: fix Windows build

Summary:
Watchman's GitHub Action has been failing because of the use of `set-env` is deprecated due to security issues. See https://github.blog/changelog/2020-10-01-github-actions-deprecating-set-env-and-add-path-commands/ for details.

See https://github.com/facebook/watchman/runs/1520165260?check_suite_focus=true for example of failures.

To fix it we just need to write to the special environment file.

Subject: [PATCH 1584/1987] Forced watchman daemon to always operate in non
 elevated mode on Windows (#878)

Summary:
Recently I found that its impossible to access elevated Watchman daemon from non-elevated process on Windows.

```
events.js:174
      throw er; // Unhandled 'error' event
      ^
Error: connect EPERM \\.\pipe\watchman
    at PipeConnectWrap.afterConnect [as oncomplete] (net.js:1106:14)
Emitted 'error' event at:
    at Socket.<anonymous> (C:\open\ovrsource\unity\socialvr\_js\node_modules\fb-watchman\index.js:118:12)
    at Socket.emit (events.js:198:13)
    at emitErrorNT (internal/streams/destroy.js:91:8)
    at emitErrorAndCloseNT (internal/streams/destroy.js:59:3)
    at process._tickCallback (internal/process/next_tick.js:63:19)
```

To fix this, it was suggested by wez to use [his library](https://github.com/wez/EleDo) to force Watchman daemon always start in normal mode on Windows. In this stack of commits I did integrated his library into project and used it to force daemon restart in normal mode when spawned from elevated terminal.

To make it happen, I checked-in library sources and created proxy project which depends on the initial library and contains header bindings and cmake configuration. I did copy pasted Rust cmake macroses from another facebook project - eden, and also created analogue of autogen.sh but for Windows - autogen.cmd.

Pull Request resolved: https://github.com/facebook/watchman/pull/878

Test Plan:
Launch elevated terminal
Start watchman.exe produced from sources
Observe daemon starting and answering
In process monitor, observe watchman.exe process running under user group

Subject: [PATCH 1610/1987] Add support for `extra_cmake_defines`

Summary:
`extra_cmake_defines` are extra flags that are passed to cmake when
compiling each one of the dependencies. For instance:
```
$ ./opensource/fbcode_builder/getdeps.py  build f4d --extra-cmake-define='{"CMAKE_CXX_FLAGS": "-mavx2 -mfma -mavx -mf16c -march=native"}'
```
It takes a json map as input, which can take a list of defines (key value
pairs).

Subject: [PATCH 1613/1987] Migrate bistro to getdeps

Summary:
This took a lot of cmake fuckery. I am guessing it will break the current travis-ci.org based build, since it no longer downloads gflags.

As I put this diff up, mvfst (a dependency of quic (a dependency of proxygen)) is not building right now due to another diff - a fix is in progress but isn't landed yet. I applied the fix locally for the test plan, but didn't include it in the diff.

Subject: [PATCH 1631/1987] always write log files as UTF-8 to avoid cp1252
 encoding errors

Summary:
The log file should be opened with a defined encoding rather than
whatever the platform default is. On Windows, that might be cp1252,
which throws an encoding error when the text is unicode.

Subject: [PATCH 1651/1987] openssl: update to 1.1.1i

Summary:
I've been trying to get EdenFS to compile on an M1 mac, and openssl only
support these starting with 1.1.1i. From their changelog:

    *) Add support for Apple Silicon M1 Macs with the darwin64-arm64-cc target.
     [Stuart Carnie]

Let's start by upgrading openssl.

Subject: [PATCH 1654/1987] ninja: upgrade and build from source on macOS

Summary:
On macOS, ninja only provides prebuilt Intel binaries, not arm64 ones. Since we
need to have a native arm64 ninja to be able to build binaries for the M1,
let's compile it from scratch on macOS too. Compiling it takes less than 30s so
it shouldn't add any notable cost to any builds.

Subject: [PATCH 1760/1987] cmake: set CMAKE_CXX_FLAGS in
 FBCompilerSettingsUnix.cmake

Summary:
It looks like the various CMAKE_CXX_FLAGS_* are simply ineffective, and I'm not
sure why, setting CMAKE_CXX_FLAGS does work though, and CMake appears to add
some release/debug flags to it when generating Ninja files.

Subject: [PATCH 1768/1987] forward env vars through tpx

Summary:
The migration to tpx broke Watchman's tests because test_bser relies on YARN_YARN_OFFLINE_MIRROR being set in the environment and tpx doesn't forward environment variables into the test.

Explicitly forward them ourselves.

Subject: [PATCH 1808/1987] apply upgraded black 21.4b2 formatting to fbsource

Summary:
This applies the formatting changes from black v21.4b2 to all covered
projects in fbsource. Most changes are to single line docstrings, as black
will now remove leading and trailing whitespace to match PEP8. Any other
formatting changes are likely due to files that landed without formatting,
or files that previously triggered errors in black.

Any changes to code should be AST identical. Any test failures are likely
due to bad tests, or testing against the output of pyfmt.

Subject: [PATCH 1823/1987] exception_wrapper thrown variant via abi/runtime

Summary:
Reimplement `folly::exception_wrapper` thrown variant not to need to cache any pointers and rather to access the exception object and runtime type, and to perform runtime upcasting, via the platform runtime.

This both simplifies and extends the capability of the thrown variant.

Subject: [PATCH 1844/1987] exception_wrapper thrown variant via abi/runtime

Summary:
Reimplement `folly::exception_wrapper` thrown variant not to need to cache any pointers and rather to access the exception object and runtime type, and to perform runtime upcasting, via the platform runtime.

This both simplifies and extends the capability of the thrown variant.

Subject: [PATCH 1860/1987] Fix openr.thrift Python Module Build

Summary:
Add Dockerfile build for openr.thrift python module.

The python module is built by:
1. Building and installing Facebook libraries with fbcode_builder
2. Building Open/R
3. Generating Cython files from thrift files with the FB thrift compiler
4. Generating C++ files from the Cython modules with the Cython compiler
5. Compiling the C++ modules into shared objects

Future work for building and distributing Breeze:

- Fix the hacks in build_breeze.sh, see comments therein
- Use a staged Dockerfile build for the Open/R and Breeze build
- Install openr.thrift. The openr.thrift shared objects are build and
  stored in the Docker image generated by Dockerfile, but are unused.
- Install all the openr python submodules in a single openr site-package
- Add cross-compilation to the openr.thrift build. This is needed for
  Terragraph
- Upload the openr python package to PyPi

Subject: [PATCH 1865/1987] exception_wrapper thrown variant via abi/runtime

Summary:
Reimplement `folly::exception_wrapper` thrown variant not to need to cache any pointers and rather to access the exception object and runtime type, and to perform runtime upcasting, via the platform runtime.

This both simplifies and extends the capability of the thrown variant.

Subject: [PATCH 1869/1987] feat: add support for compiling open/r on 64-bit
 arm linux (#95)

Summary:
Description:

Prior to this patch it was not possible to run open/r on linux running on ARM due to cmake and openssl being harded to download/compile for the x86_64 arch.

In order to prevent such problem this patch actively compiles cmake instead of using pre-compiled binaries and also allows the OpenSSLBuilder to provide the correct build args to openssl, thus not trying to compile or run x86_64 software.

Pull Request resolved: https://github.com/facebook/openr/pull/95

Test Plan: * built the project by using ./build/build_openr.sh

Summary:
The testpilot command line getdeps generated was not suitable for tpx

environment variable.

Reorder a few things to at least make filtering work.

Subject: [PATCH 1890/1987] win: add --return-nonzero-on-failures to
 sc_testpilot

Summary:
For whatever reason, sc_testpilot default to --return-zero-on-failures, which
means that test failures are simply not reported properly to the signal box.
Fix that by explicitely passing --return-nonzero-on-failures

Subject: [PATCH 1893/1987] Enable fb dynamicconfig loading inside eden
 backingstore

Summary:
Reenables dynamicconfig loading with eden backingstore. Previously it
broke edenfs-windows-release, but we believe the
opensource/fbcode_builder/manifests/eden tweak has fixed it.

Summary:
BSD readlink doesn't have -f.

I'm not using TravisCI, however docker is still convenient for reproducing builds locally.

Subject: [PATCH 1907/1987] Mark zstd as a dependency of fizz

Summary:
I don't understand why we have both manifests/specs; I was assuming one was generated from the other,
but I don't see a at-generated and grep doesn't show up anything, so both are manual edits.

Subject: [PATCH 1909/1987] Move FindZstd.cmake into fbcode_builder

Summary:
A bunch of existing projects vendor it into their own CMake folder. But these
same projects also have fbcode_builder's CMake directory in their CMAKE_MODULE_PATH,
so move FindZstd here.
