Release Notes for Couchbase Client Library C 2.1.3 GA (10 September 2013)

New Features and Behavior Changes in 2.1.3

• Use cluster type connection for cbc-bucket-flush. Although flush command is accessible for bucket type connections, cbc-bucket-flush doesn't use provided bucket name to connect to, therefore it will fail if the bucket name isn't "default".

• Allow to make connect order deterministic. It allows the user to toggle between deterministic and random connect order for the supplied nodes list. By default it will randomize the list.

Fixes in 2.1.3

• Updated gtest to version 1.7.0. Fixes issue with building test suite with new XCode 5.0 version being released later this month.

• Do not try to parse config for LCB_TYPE_CLUSTER handles. It fixes timouts for management operations (like 'cbc bucket-create', 'cbc bucket-flush', 'cbc bucket-delete' and 'cbc admin')

  Issues : CCBC-265

• Skip unfinished SASL commands on rebalance. During rebalance, it is possible that the newly added server doesn't have chance to finish SASL auth before the cluster will push config update, in this case packet relocator messing cookies. Also the patch makes sure that SASL command/cookie isn't mixing with other commands

  Issues : CCBC-263

• Do not allow to use Administrator account for LCB_TYPE_BUCKET

• Fig segmentation faults during tests load of node.js. Sets inside_handler on socket_connected. Previously we were always using SASL auth, and as such, we wouldn't flush packets from the cmd_log using server_send_packets (which calls apply_want). apply_want shouldn't be called more than once per event loop entry -- so this sets and unsets the inside_handler flag.

  Issues : CCBC-258

• Added support of libuv 0.8

• Close config connection before trying next node. It will fix asserts in case of the config node becomes unresponsive, and the threshold controlled by LCB_CNTL_CONFERRTHRESH and lcb_cntl(3)

Release Notes for Couchbase Client Library C 2.1.2 GA (27 August 2013)

Fixes in 2.1.2

• Use bucket name in SASL if username omitted. Without this fix, you can may encounter a segmentation faults for buckets, which are not protected by a password.

  Issues : CCBC-253 CCBC-254

• Preserve IO cookie in options_from_info when using v0 plugins with user-provided IO loop instance. This issue was introduced in 2.1.0.

• Display the effective IO backend in cbc-version. This is helpful to quickly detect what is the effective IO plugin on a given system.

Release Notes for Couchbase Client Library C 2.1.1 GA (22 August 2013)

New Features and Behavior Changes in 2.1.1

• Fallback to 'select' IO plugin if default plugin cannot be loaded. On UNIX-like systems, default IO backend is 'libevent', which uses third-party library might be not available at the run-time. Read in lcb_cntl(3couchbase) man page in section LCB_CNTL_IOPS_DEFAULT_TYPES about how to determine effective IO plugin, when your code chose to use LCB_IO_OPS_DEFAULT during connection instantiation. The fallback mode doesn't affect application which specify IO backend explicitly.

  Issues : CCBC-246

• Skip misconfigured nodes in the list. New lcb_cntl(3couchbase) added to control whether the library will skip nodes in initial node list, which listen on configuration port (8091 usually) but doesn't meet required parameters (invalid authentication or missing bucket). By default report this issue and stop trying nodes from the list, like all previous release. Read more at man page lcb_cntl(3couchbase) in section LCB_CNTL_SKIP_CONFIGURATION_ERRORS_ON_CONNECT

  Issues : CCBC-192

• Distribute debug information with release binaries on Windows

  Issues : CCBC-245

Fixes in 2.1.1

• Do not use socket after failout. Fixes segmentation faults during rebalance.

  Issues : CCBC-239

• Use provided credentials for authenticating to the data nodes. With this fix, it is no longer possible to use Administrator credentials with a bucket. If your configuration does so, you must change the credentials you use before applying this update. No documentation guides use of Administrator credentials, so this change is not expected to affect few, if any deployments.

• Do not disable config.h on UNIX-like platforms. It fixes build issue, when application is trying to include plugins from the tarball.

  Issues : CCBC-248

Release Notes for Couchbase Client Library C 2.1.0 GA (18 August 2013)

New Features and Behavior Changes in 2.1.0

• New backend select. This backend is based on the select(2) system call and its Windows version. It could be considered the most portable solution and is available with the libcouchbase core.

• API for durability operations. This new API is based on lcb_observe(3) and allows you to monitor keys more easily. See the man pages lcb_durability_poll(3) and lcb_set_durability_callback(3) for more info.

  Issues : CCBC-145

• New backend libuv. This backend previously was part of the couchnode project and is now available as a plugin. Because libuv doesn't ship binary packages there is no binary package libcouchbase2-libuv. You can build plugin from the source distribution, or through the libcouchbase-dev or libcouchbase-devel package on UNIX like systems.

  Issues : CCBC-236

• New backend iocp. This is a Windows specific backend, which uses "I/O Completion Ports". As a part of the change, a new version of plugin API was introduced which is more optimized to this model of asynchronous IO.

• New configuration interface lcb_cntl(3) along with new tunable options of the library and connection instances. In this release the following settings are available. See the man page for more information and examples.:

  • LCB_CNTL_OP_TIMEOUT operation timeout (default 2.5 seconds)

  • LCB_CNTL_CONFIGURATION_TIMEOUT time to fetch cluster configuration. This is similar to a connection timeout (default 5 seconds)

  • LCB_CNTL_VIEW_TIMEOUT timeout for couchbase views (default 75 seconds)

  • LCB_CNTL_HTTP_TIMEOUT timeout for other HTTP operations like RESTful flush, bucket creating etc. (default 75 seconds)

  • LCB_CNTL_RBUFSIZE size of the internal read buffer (default 32768 bytes)

  • LCB_CNTL_WBUFSIZE size of the internal write buffer (default 32768 bytes)

  • LCB_CNTL_HANDLETYPE type of the lcb\_t handler (readonly)

  • LCB_CNTL_VBCONFIG returns pointer to VBUCKET_CONFIG_HANDLE (readonly)

  • LCB_CNTL_IOPS get the implementation of IO (lcb_io_opt_t)

  • LCB_CNTL_VBMAP get vBucket ID for a given key

  • LCB_CNTL_MEMDNODE_INFO get memcached node info

  • LCB_CNTL_CONFIGNODE_INFO get config node info

  • LCB_CNTL_SYNCMODE control synchronous behavior (default LCB_ASYNCHRONOUS)

  • LCB_CNTL_IP6POLICY specify IPv4/IPv6 policy (default LCB_IPV6_DISABLED)

  • LCB_CNTL_CONFERRTHRESH control configuration error threshold (default 100)

  • LCB_CNTL_DURABILITY_TIMEOUT durability timeout (default 5 seconds)

  • LCB_CNTL_DURABILITY_INTERVAL durability polling interval (default 100 milliseconds)

  • LCB_CNTL_IOPS_DEFAULT_TYPES get the default IO types

  • LCB_CNTL_IOPS_DLOPEN_DEBUG control verbose printing of dynamic loading of IO plugins.

Fixes in 2.1.0

• Fixed bug when REPLICA_SELECT didn't invoke callbacks for negative error codes

  Issues : CCBC-228

• Fixed bug when LCB_REPLICA_FIRST fails if first try does not return key

  Issues : CCBC-229

Known Issues in 2.1.0

• From the release the 2.1.0 package libcouchbase2 will not install an IO backend automatically. If you are upgrading, there are no changes because you have already libcouchbase2-libev or libcouchbase2-libevent packages installed. For new installations, a backend must be selected for the client library to work correctly.

  If for example you are using the PHP SDK, the old way, which works for pre-2.1.0 versions is:

  # DEB-based systems
  shell> sudo apt-get install libcouchbase2 libcouchbase-dev
  # RPM-based systems
  shell> sudo yum install libcouchbase2 libcouchbase-devel
  

  But a more explicit way to do this, which works for all versions (including 2.1.0) is:

  # DEB-based systems
  shell> sudo apt-get install libcouchbase2-libevent libcouchbase-dev
  # RPM-based systems
  shell> sudo yum install libcouchbase2-libevent libcouchbase-devel
  

Release Notes for Couchbase Client Library C 2.0.7 GA (10 July 2013)

New Features and Behavior Changes in 2.0.7

• Improve lcb\_get\_replica(). Now it is possible to choose between three strategies:

  1. LCB_REPLICA_FIRST : Previously accessible and now the default, the caller will get a reply from the first replica to successfully reply within the timeout for the operation or will receive an error.

  2. LCB_REPLICA_ALL : Ask all replicas to send documents/items back.

  3. LCB_REPLICA_SELECT : Select one replica by the index in the configuration starting from zero. This approach can more quickly receive all possible replies for a given topology, but it can also generate false negatives.

  Note that applications should not assume the order of the replicas indicates more recent data is at a lower index number. It is up to the application to determine which version of a document/item it may wish to use in the case of retrieving data from a replica.

  Issues : CCBC-183

Release Notes for Couchbase Client Library C 2.0.6 GA (07 May 2013)

New Features and Behavior Changes in 2.0.6

• Added an example to properly use the bucket credentials for authentication instead of administrator credentials

  Issues : CCBC-179

• Add Host header in http request http://cbugg.hq.couchbase.com/bug/bug-555 points out that Host is a required field in HTTP 1.1

  Issues : CCBC-201

Fixes in 2.0.6

• Fix segfault when rebalancing. When a (!connected) server is reconnected, the tasks in its "pending" buffer will be moved into "output" buffer. If its connection is broken again immediately, relocate_packets() will go to wrong path.

  Issues : CCBC-188

• Don't try to switch to backup nodes when timeout is reached

  Issues : CCBC-202

• Fix compile error with sun studio. "src/event.c", line 172: error: statement not reached (E_STATEMENT_NOT_REACHED)

• Don't invoke HTTP callbacks after cancellation, because user code might assume a previously-freed resource is still valid

• Check if SASL struct is valid before disposing

  Issues : CCBC-188

• example/yajl/couchview.c: pass cookie to the command Fixes coredump when executing./examples/yajl/couchview

Release Notes for Couchbase Client Library C 2.0.5 GA (05 April 2013)

New Features and Behavior Changes in 2.0.5

• pillowfight example updated to optionally use threads

Fixes in 2.0.5

• Try to search the --libdir for modules if dlopen fails to find the module in the default library path

• New compat mode (experimental) for configuration caching. See man lcb_create_compat

  Issues : CCBC-190

• Fix reconnecting issues on windows (http://review.couchbase.org/25170 and http://review.couchbase.org/25155)

• Fix build on FreeBSD (http://review.couchbase.org/25289)

Release Notes for Couchbase Client Library C 2.0.4 GA (06 March 2013)

  Issues : CCBC-147

• Work properly on systems where EWOULDBLOCK != EAGAIN

  Issues : CCBC-175

• The library stops iterating backup nodes list if the next one isn't accessible.

  Issues : CCBC-182

• The bootstrap URI is not parsed correctly

  Issues : CCBC-185

• Segmentation fault when the hostname resolved into several addresses and first of them reject couchbase connections.

  Issues : CCBC-180

Release Notes for Couchbase Client Library C 2.0.3 GA (06 February 2013)

New Features and Behavior Changes in 2.0.3

• Add a new library: libcouchbase_debug.so (see include/libcouchbase/debug.h) which is a new library that contains new debug functionality.

• Added manual pages for the library.

Fixes in 2.0.3

• Observe malfunctions in the case of multiple keys and server failure.

  Issues : CCBC-155

• Reset internal state on lcb_connect(). Allow caller to use lcb_connect() multiple times to implement reconnecting using the same lcb_t instance. Also it sets up the initial-connection timer for users who don't use lcb_wait() and drive IO loop manually.

  Issues : CCBC-153

• Invalid read in libevent plugin, when the plugin compiled in 1.x mode

  Issues : CCBC-171

• Shrink internal lookup tables (and reduce the size of lcb_t)

• Issues : CCBC-156

Release Notes for Couchbase Client Library C 2.0.2 GA (04 January 2013)

Fixes in 2.0.2

• Document LCB_SERVER_BUG and LCB_PLUGIN_VERSION_MISMATCH. Enhance the the lcb_strerror test to detect undocumented error codes.

• Commands sent to multiple servers fail to detect the respose if mixed with other commands.

  Issues : CCBC-150

• Under high load the library could generate LCB_ETIMEDOUT errors without reason owing to internal limitations.

  Issues : CCBC-153

• Cancellation of the HTTP request might lead to memory leaks or to segfaults (2e3875c2).

  Issues : CCBC-151

Release Notes for Couchbase Client Library C 2.0.1 GA (11 December 2012)

New Features and Behavior Changes in 2.0.1

• SystemTap and DTrace integration

Fixes in 2.0.1

• Fix a memory leak on the use of http headers

  Issues : CCBC-130

• libev-plugin: delay all timers while the loop isn’t active. It will fix LCB_ETIMEOUT in the following scenario:

  • connect the instance

  • sleep for time greater than default timeout (e.g. 3 seconds)

  • schedule and execute a command (it will be timed out immediately)

• Do not abort when purging SASL commands

  Issues : CCBC-136

• Fix possible SEGFAULT. Not-periodic timers are destroyed after calling user’s callback, after that library performed read from freed pointer.

• Compensate for cluster nodes lacking couchApiBase

  Issues : CCBC-131

• Ensure HTTP works even when the network may be unreliable. This changeset encompasses several issues which had been found with HTTP requests during network errors and configuration changes. Specifically some duplicate code paths were removed, and the process for delivering an HTTP response back to the user is more streamlined.

  Issues : CCBC-132, CCBC-133

• libev-plugin: reset IO event on delete. We need to reset it, because it might be re-used later

• Make library C89 friendly again

Release Notes for Couchbase Client Library C 2.0.0 GA (27 November 2012)

New Features and Behavior Changes in 2.0.0

• Add the CAS to the delete callback

Fixes in 2.0.0

• Minor update of the packaging layout:

  • libcouchbase-all package comes without version

  • extract debug symbols from libcouchbase-{bin,core} to libcouchbase-dbg package

• Install unlock callback in synchronous mode

Release Notes for Couchbase Client Library C 2.0.0beta3 Beta (21 November 2012)

New Features and Behavior Changes in 2.0.0beta3

• Try all known plugins for LCB_IO_OPS_DEFAULT in run time

• Allow to use ‘cbc-hash’ with files

• Create man pages for cbc and cbcrc

• Use dynamic versioning for plugins

• Lookup the plugin symbol also in the current executable image.

  Issues : CCBC-114

• Allow the user to specify a different hash key. All of the data operations contains a hashkey and nhashkey field. This allows you to “group” items together in your cluster. A typical use case for this is if you’re storing lets say data for a single user in multiple objects. If you want to ensure that either all or none of the objects are available if a server goes down, it could be a good idea to locate them on the same server. Do bear in mind that if you do try to decide where objects is located, you may end up with an uneven distribution of the number of items on each node. This will again result in some nodes being more busy than others etc. This is why some clients doesn’t allow you to do this, so bear in mind that by doing so you might not be able to get your objects from other clients.

  Issues : CCBC-119

• Add documentation about the error codes

  Issues : CCBC-87

• Add lcb_verify_compiler_setup(). This function allows the “user” of the library to verify that the compiler use a compatible struct packing scheme.

Fixes in 2.0.0beta3

• lcb_error_t member in the http callbacks shouldn’t reflect the HTTP response code. So the error code will be always LCB_SUCCESS if the library managed to receive the data successfully.

  Issues : CCBC-118

• Fix cbc-bucket-create. `sasl-password' is misspelled, and it fails to parse the command line option.

• Remove libtool version from the plugins

• Do not allow admin operations without authentication

• check for ewouldblock/eintr on failed send

• Purge stale OBSERVE packets

  Issues : CCBC-120

• Allow to use gethrtime() from C++

• Remove unauthorized asserion (d344037). The lcb_server_send_packets() function later check if the server object connected and establish connection if not (with raising possible errors)

  Issues : CCBC-113

• Don’t use the time_t for win32. When compiling from php it turns out that it gets another size of the time_t type, causing the struct offsets to differ.

• Reformat and refactor lcb_server_purge_implicit_responses:

  • move packet allocation out of GET handler

  • dropping NOOP command shouldn’t return error code

  Issues : CCBC-120

• Try to switch another server from backup list on timeout

  Issues : CCBC-122

• Timer in libev uses double for interval. Ref: http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod\#code\_ev\_timer\_code\_relative\_and\_opti

• Fix illegal memory access. Reconnect config listener if the config connection was gone without proper shutdown.

  Issues : CCBC-104

• Fix using freed memory (was introduced in 4397181)

• Return zero from do_read_data() if operations_per_call reached. The `operations_per_call' limit was introduced to prevent from freezing event loop. But in the function variable rv could store two different results and in case of reaching this limit it is returning number of the processed records, which is wrong. The function should return either zero (success) or non-zero (failure).

  Issues : CCBC-115

Release Notes for Couchbase Client Library C 2.0.0beta2 Beta (12 October 2012)

New Features and Behavior Changes in 2.0.0beta2

• Implement a new libev plugin. It is compatible with both libev3 and libev4.

• Allow libcouchbase to connect to an instance without specifying bucket. It is useful when the bucket not needed, e.g. when performing administration tasks.

• Allow users to build the library without dependencies. For example, without plugins at all. This may be useful if the plugin is implemented by or built into the host application.

• Allow users to use environment variables to pick the event plugin

• Add a new interface version for creating IO objects via plugins

• Allow to disable CXX targets

• Allow users to install both libraries (2.x and 1.x) on the same system.

• Cleanup HTTP callbacks. Use the same callbacks both for Management and View commands, and rename them to lcb_http_complete_callback and lcb_http_data_callback.

• Add support for raw http requests. libcouchase already contains all the bits to execute a raw http request, except for the possibility to specify a host:port, username and password.

• Make the content type optional for lcb_make_http_request()

Fixes in 2.0.0beta2

• Fix invalid memory access in cbc tool. Affected command is cbc-bucket-create

• Search ev.h also in ${includedir}/libev

• Fix password memory leak in http.c (7e71493)

• lcb_create: replace assert() with error code

• Breakout event loop in default error_callback. This provides better default behavior for users who haven’t defined global error callback.

  Issues : CCBC-105

• Fix linked event/timer lists for win32

  Issues : CCBC-103

• Fix SEGFAULT if IO struct is allocated not by the lcb_create()

• Fix memory leak after an unsuccessful connection

• lcb_connect() should honor the syncmode setting. Automatically call lcb_wait() when in synchronous mode

Release Notes for Couchbase Client Library C 2.0.0beta Beta (13 September 2012)

New Features and Behavior Changes in 2.0.0beta

• Bundle Windows packages as zip archives

• Refactor the API. This is a full redesign of the current libcouchbase API that’ll allow us to extend parts of the API without breaking binary compatibility. Also it renames all functions to have lcb prefix instead of libcouchbase and LCB/LIBCOUCHBASE in macros.

• Implement getter for number of nodes in the cluster: lcb_get_num_nodes()

• Add lcb_get_server_list() to get current server list

• Deliver HTTP headers via callbacks

• Implement RESTful flush in the cbc toolset

• Merge lcb_get_locked into lcb_get function

• Bundle libvbucket

Fixes in 2.0.0beta

• Fix a problem with allocating too few slots in the backup_nodes. Fixes illegal memory access.

• Include sys/uio.h. Needed by OpenBSD

• Added --enable-fat-binary. Helps to solve issues when linking with fat binaries on MacOS.

• Differentiate between TMPFAILs. This allows a developer to know if the temporary condition where the request cannot be handled is due to a constraint on the client or the server.

  Issues : CCBC-98

• Correct buffer length for POST/PUT headers

  Issues : CCBC-96

• Fix switching to backup node in case of server outage

  Issues : CCBC-91

• Fix locking keys in multi-get mode

• Release the memory allocated by the http parser

  Issues : CCBC-89

• Fix initialization of backup nodes array. The code switching nodes relies on NULL terminator rather than nbackup_nodes variable. Fixes illegal memory access.

  Issues : CCBC-90

• Default to IPv4 only

  Issues : CCBC-80

• Reset timer for commands with NOT_MY_VBUCKET response

  Issues : CCBC-91

• Sync memcached/protocol_binary.h. Pull extra protocol_binary_datatypes declarations.

• Fix bug where HTTP method is not set

• Don’t try to put the current node last in the backup list. This may cause “duplicates” in the list if the REST server returns another name for the server than you used. Ex: you specify “localhost” and the REST response contains 127.0.0.1

• Release ringbuffer in lcb_purge_single_server

  Issues : CCBC-92

Release Notes for Couchbase Client Library C 1.1.0dp9 Developer Preview (27 July 2012)

Fixes in 1.1.0dp9

• Render auth credentials for View requests. libcouchbase_make_http_request() won’t accept credentials anymore. It will pick them bucket configuration.

Release Notes for Couchbase Client Library C 1.1.0dp8 Developer Preview (27 July 2012)

New Features and Behavior Changes in 1.1.0dp8

• Allow the user to get the number of replicas using libcouchbase_get_num_replicas()

• Separate HTTP callbacks for couch and management requests

• Implement read replica

  Issues : CCBC-82

• Let users detect if the event loop running already using libcouchbase_is_waiting() function.

• Add OBSERVE command

  Issues : CCBC-15

• Allow users to specify content type for HTTP request.

• Allow a user to breakout from the event loop in callbacks using libcouchbase_breakout()

• New cbc commands and options:

  • cbc-view (remove couchview example)

  • cbc-verbosity

  • cbc-admin

  • cbc-bucket-delete

  • cbc-bucket-create

  • Add -p and -r options to cbc-cp to control persistence (uses OBSERVE internally)

• Allow the client to specify the verbosity level on the servers using lcb_set_verbosity() function.

• Implement general purpose timers. It is possible for users to define their own timers using libcouchbase_timer_create() function. (See headers for more info). Implement multiple timers for windows

  Issues : CCBC-85

Fixes in 1.1.0dp8

• Claim that server has data in buffers if there are HTTP requests pending. Without this patch the event loop can be stopped prematurely.

• Make libcouchbase_wait() re-entrable

• Fix to handle the case when View base doesn’t have URI schema.

• Bind timeouts to server sockets instead of commands. This means that from this point timeout interval will be started from the latest IO activity on the socket. This is a behavior change from the 1.0 series.

• Use separate error code for ENOMEM on the client

  Issues : CCBC-77

Release Notes for Couchbase Client Library C 1.1.0dp7 Developer Preview (19 June 2012)

New Features and Behavior Changes in 1.1.0dp7

• Implement function to execution management requests. Using libcouchbase_make_management_request() function you can configure the cluster, add/remove buckets, rebalance etc. It behaves like libcouchbase_make_couch_request() but works with another endpoint.

• Add support for notification callbacks for configuration changes. Now it is possible to install a hook using function libcouchbase_set_configuration_callback(), and be notified about all configuration changes.

Fixes in 1.1.0dp7

  • Add suffix to cbc command implementations;

  • Fix guards for socket errno macros;

  • Define size_t types to fix MSVC 9 build;

  • MSVC 9 isn’t C99, but has stddef.h, so just include it.

Release Notes for Couchbase Client Library C 1.1.0dp5 Developer Preview (06 June 2012)

New Features and Behavior Changes in 1.1.0dp5

• Implement ‘cbc-hash’ to get server/vbucket for given key

Fixes in 1.1.0dp5

• The library doesn’t depend on pthreads (eliminates package lint warnings)

Release Notes for Couchbase Client Library C 1.1.0dp4 Developer Preview (05 June 2012)

Fixes in 1.1.0dp4

• cbc: strtoull doesn’t exist on win32, therefore use C++ equivalent.

Release Notes for Couchbase Client Library C 1.1.0dp3 Developer Preview (03 June 2012)

New Features and Behavior Changes in 1.1.0dp3

• Implement GET_LOCKED (GETL) command

  Issues : CCBC-68

• Implement UNLOCK_KEY (UNL) command

  Issues : CCBC-68

Fixes in 1.1.0dp3

• Timeouts can occur during topology changes, rather than be correctly retried. Send the retry-packet to new server

  Issues : CCBC-64

• Fix ringbuffer_memcpy() (36afdb2). Fix ringbuffer_is_continous().

• A hang could occur in libcouchbase_wait() after the timeout period. Check for breakout condition after purging servers

  Issues : CCBC-62

• Destroy view requests items when server get destroyed. Fixes memory leaks.

• A fix for a buffer overflow with the supplied password as has been integrated. While it is a buffer overflow issue, this is not considered to be a possible security issue because the password to the bucket is not commonly supplied by an untrusted source

  Issues : RCBC-33

• A small memory leak can occur with frequent calls to libcouchbase_create() and libcouchbase_destroy()

  Issues : CCBC-65

• Use vbucket_found_incorrect_master() to get correct server index during relocating buffers. Pick up cookies from pending buffer unless node connected.

• Do not call View callbacks for cancelled requests

• hashset.c: iterate over whole set on rehashing. Fixes memory leaks related to hash collisions (905ef95)

Release Notes for Couchbase Client Library C 1.1.0dp2 Developer Preview (10 April 2012)

Fixes in 1.1.0dp2

• Don’t wait for empty buffers. If called with no operations queued, libcouchbase_wait() will block forever. This means that a single threaded application that calls libcouchbase_wait() at different times to make sure operations are sent to the server runs the risk of stalling indefinitely. This is a very likely scenario.

  Issues : CCBC-59

• Don’t define size_t and ssize_t for VS2008

• Fix segfault while authorizing on protected buckets (211bb04)

Release Notes for Couchbase Client Library C 1.1.0dp Developer Preview (05 April 2012)

New Features and Behavior Changes in 1.1.0dp

• This release adds new functionality to directly access Couchbase Server views using the libcouchbase_make_couch_request() function. See the associated documentation and header files for more details.

Fixes in 1.1.0dp

• Request the tap bytes in a known byte order (adf2b30)

  Issues : MB-4834

• Check for newer libvbucket
