ChangeLog

2020-05-28  Tobias Brox <t-caldav@tobixen.no>
	* caldav/lib/namespace.py - The http://apple.com/ns/ical/ namespace should not be passed in every request
	* caldav/objects.py - bugfix, URLs should be quoted, and not contain '@' etc.  That ical namespace for calendar color should be imported.  refactoring, the new search method can replace quite some duplicated code.
	* docs/source/index.rst - comment on calendar-color and calendar-order, non-standard extentions supported by many server implementations.  Add a section for objectives/scope of the library.
	* tests/compatibility_issues.py - should explicitly tell that calendarcolor and calendarorder should be tessted.
	* tests/conf.py - it should be possible to disable xandikos/radicale testing without specifying server parameters in conf_private.py
	* tests/conf_private.py.EXAMPLE - try to list up all flags
	* tests/test_caldav.py - fix to support upstream changes in radicale that breaks the radicale server creation, make most of the duplication test skipable (due to bedeworks), tests for calendar color and order

2020-05-20  Tobias Brox <t-caldav@tobixen.no>
	* caldav/lib/python_utilities.py - still some more python2/python3-unicode/str/byte problem solving
	* caldav/objects.py - splitting up the date_search into three submethods, making it easier to do custom searches.  icalendar support.  Making sure all modifications through either vobject, icalendar or raw data is honored.
	* docs/source/index.rst - icalendar support
	* examples/basic_usage_examples.py - vobject support
	* setup.py - icalendar is now a test requirement (and also an optional requirement for library users)

2020-05-19  Tobias Brox <t-caldav@tobixen.no>
	* caldav/davclient.py - save the auth object, to avoid lots of failed autentications on servers not handling digestauth.

2020-05-14  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - old zimbra tweaks are already obsoleted and has to be replaced with new ones.  Usage of the word "save" rather than "add" where it's possible both to create a new item or update an old.
	* tests/compatibility_issues.py - trying to organize all the compatibility problems found through the tests in one file
	* tests/test_caldav.py - support for improved passing of compatibility_issues into server params.  Added hooks for ignoring known incompatibilities from servers.

2020-05-13  Tobias Brox <t-caldav@tobixen.no>
	* .travis.yml - attempt on getting CI with travis on github to work
	* caldav/lib/namespace.py - I've finally understood and ironed out some weird bugfix from 2014

	* caldav/objects.py - improved error messages

2019-11-15  Tobias Brox <t-caldav@tobixen.no>
	* caldav/davclient.py - ref https://github.com/python-caldav/caldav/issues/81 and jimays at github, some versions of the request libary may produce a response object without the reason attribute.

2019-09-30  Stephane Blondon <stephane.blondon@gmail.com>
	* Makefile - fix a Makefile
	* setup.py - fix tox

2019-05-29  Tobias Brox <t-caldav@tobixen.no>
	* .travis.yml - xandikos cannot be installed on python2.7, but we still want to run the available tests
	* caldav/lib/error.py - ProppatchError was not defined, ref https://github.com/python-caldav/caldav/issues/54.  Also added a common base class DAVError, and made sure the error referenced in #54 will never reappear, even if new methods are added to DAVClient.
	* tests/test_caldav.py - testing that the bug referenced in #54 has been properly plugged in caldav/lib/error.py
	* caldav/elements/cdav.py - fixing a retention problem - the timezone fixes done recently was not compatible with python 2.7 nor 3.5.
	* caldav/objects.py - revisiting https://github.com/python-caldav/caldav/issues/54 - "... is not None" feels more kosher than "... != None", and added TODO-comment that we need to do more research when those variables are None.  Bugfix on the error handling for multi-status-return, should return the specific error code and error message found, not the "207 Multi-Status".
	* setup.py - reintroducing dependencies pytz and tzlocal - but only for old python versions
	* tests/conf.py - test_xandikos should be defaulted to False if xandikos not present (as it can never be present on 2.7)
	* tests/test_cdav.py - make the test python2.7-compatible (though some of the testing is a bit moot, as same code path is used in code and in test)

2019-05-28  Tobias Brox <t-caldav@tobixen.no>
	* .travis.yml - ref https://github.com/python-caldav/caldav/issues/57, fixing automated test runs after each commit and on each pull request.
	* setup.py - new default tests depends on xandikos
	* tests/conf.py - new defaults - testing towards external unreliable public test servers are disabled by default, an internal xandikos server is set up and tests are by default run towards that one
	* tests/conf_private.py.EXAMPLE - new file, setting an example on how to run tests towards personal servers
	* tests/test_caldav.py - added a test class that spawns a xandikos server instance and runs the functional test suite towards it.  Unfortunately it only works under python3.  Ref https://github.com/python-caldav/caldav/issues/46

2019-05-19  Jelmer Vernooij <jelmer@jelmer.uk>
	* caldav/objects.py - bugfixing

2019-05-19  Achim Herwig <achim.herwig@tngtech.com>

	* caldav/objects.py - bugfix, ref #52

2019-03-11  Tomáš Chvátal <tomas.chvatal@gmail.com>
	* MANIFEST.in - Include tests and changelog in pypi sdist tarball, ref https://github.com/python-caldav/caldav/pull/49

2019-03-11  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - bugfix: accept text/calendar (required for fetching calendar items from the xandikos server, ref https://github.com/python-caldav/caldav/issues/40

2019-03-10  Tobias Brox <t-caldav@tobixen.no>
	* setup.py - pushed the version number to 0.6.0, preparing for release
	* ChangeLog - updated with most of the activity since 2017-02
	* caldav/objects.py - "expand" in the date_search should be optional.

2019-03-09  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - preparing for introducing support for the icalendar module and making the vobject support a legacy thing.  Delaying instantiation of vobject.  Compatibility fix required by the xandikos server implementation.

2019-03-08  Tobias Brox <t-caldav@tobixen.no>
	* caldav/elements/cdav.py - proper timezone support, the support made by Alghost was not following the standard, and caused breakage with one of the servers.  Caveat: In 0.5.0, a timestamp date_search was assumed to be UTC, with the patch from Alghost a timestamp without tzinfo was passed without any time zone info (and possibly interpreted to be in the same time zone as the caldav server), with this patch it's assumed to be in the clients local timezone.  Backward compatibility may be slightly broken (and test results may depend on the time zone the tests are run under)
	* setup.py - now we're dependent on pytz and tzlocal
	* caldav/object.py - some caldav servers don't want to give us all pending TODOs in one query.  Working around it.  Credits to mayjs <johannes.may@udo.edu> for pointing out this issue and attempting to solve it.
	* test/caldav_test.py - letting one of the VTODO items in the test file be without a defined STATUS.

2018-12-05  Notmarrco <marrco@wohecha.fr>

	* setup.py - bugfix, credits to slavkoja

2017-01-26  Tobias Brox <t-caldav@tobixen.no>
	* tests/test_caldav.py - support for unique calendar IDs in the
	test framework.  Should make it possible to run tests in parallell
	against the same server and user

2017-01-26  Phyks (Lucas Verney) <phyks@phyks.me>
	* caldav/objects.py - enhancement: add the ability to add events to
	calendar using directly a vobject object, and not necessarily an ical
	string.

2017-01-24  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - bugfix: uid handling while fetching
	elements, ref

	- credits to Lucas Verney
	* tests/conf.py - make it easier to override the public test
	servers and run tests exclusively against custom test servers

2017-01-23  Cyril Roberts <cyril@hippie.io>
	* README.md - Changed the documentation to follow github
	standards, while moving the project from bitbucket/hg to
	github/git

2017-01-22  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - bugfix: after a zimbra upgrade, tests started breaking again as the data from the server was urlencoded.  Merged in bugfix for bitbucket issue #46

2017-01-03  Tobias Brox <t-caldav@tobixen.no>
	* caldav/elements/cdav.py, caldav/objects.py: found a
	Calendar-Collection tag that was nowhere to be found in the RFC,
	and that also caused tests to break against some caldav servers.

2016-05-15  Alex Martin <maddin4t0r@gmail.com>
	* caldav/objects.py - bugfix, ref pull request #21

2016-10-07  Benedykt Przybyło <b3niup@gmail.com>
	* caldav/elements/cdav.py - bugfix, Fixed namespace for Mkcalendar.

2016-04-25  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - adjustments for changes in the vobject module

	calendars() method, ref issue #51

2016-03-09  Rian Hunter <rian@alum.mit.edu>

	* setup.py - missing shebang, problem observed by jbar@freenode, #calendar-cli
	* caldav/objects.py - bugfix for problem observed by jbar@freenode, #calendar-cli

2015-11-16  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py, caldav/elements/cdav.py - attempt on solving bitbucket issue #40

2015-08-15  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py, caldav/__init__.py - vobjects did not support
	python3, so move the "import"-statement so everything not
	dependent on vobjects can work under python3.

2015-08-11  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - support for http return code 207 multi status from server

2015-05-21  Jochen Sprickerhof <bitbucket@jochen.sprickerhof.de>
	* caldav/objects.py - proper fix for issue #43

2015-05-20  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - allow copying objects.  Needed for the
	recurring todo completed functionality in calendar-cli.  Fixed
	bitbucket issue #43 (compatbility fix).  Polishing some error
	messages.

2015-05-17  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - sorting todo events by due date or dstart.
	Feature needed by the calendar-cli task management.

2015-04-27  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - generalized the calendar date search so
	todo-events also can be searched by date.  The calendar-cli task
	handling depends on this.

2015-04-25  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py - generalized the code a bit, added a
	method object_by_uid and made event_by_uid a wrapper around this
	one.  Added improved sorting functionality.  The task handling in
	calendar-cli is dependent on those features.

2015-04-21  Tobias Brox <t-caldav@tobixen.no>
	* caldav/elements/cdav.py - now support for the free-busy-query element.

	* caldav/objects.py - added FreeBusy and Journal objects, plus
	calendar methods to retrieve them, and for adding journal entries.

	* caldav/tests/test_caldav.py - added tests to add and fetch
	journal entries, and to request freebusy information.

2015-04-16  Tobias Brox <t-caldav@tobixen.no>
	* caldav/lib/error.py - added error class for the propfind method.
	Made a dict index for method name -> exception class.

	* caldav/elements/cdav.py - bugfix - "negate-condition", not
	"negate" in the TextMatch class.  Added
	SupportedCalendarComponentSet class.

	* caldav/elements/davclient.py - obscured the API a bit by
	allowing a dummy parameter to be passed to various methods.  Not
	very nice, but needed for the refactoring work in objects.py.

	* caldav/objects.py - VTODO support, new class for Todo-items with
	method for completing the task.  Calendar creation methods takes a
	list of supported element types as optional parameter.  Quite some
	refactoring, consolidating similar-looking code.  Minor bugfix
	with the event date search - asking for an expanded event list
	with an open end date is not supported by all server
	implementations, for obvious reasons.  Brushed up some docstrings
 	and prefixed some internal methods with underscore.

	* caldav/tests/test_caldav.py - VTODO support, test code that
	creates a task list, adds todo-items to it, completes todo-items,
	list them out and deletes todo-items.

2015-04-01  Tobias Brox  <t-caldav@tobixen.no>
	* caldav/objects.py - started working on VTODO support

	* caldav/tests/test_caldav.py - started working on VTODO support

2015-04-01  Tobias Brox  <t-caldav@tobixen.no>
	* caldav/lib/url.py - work on python3-support

	* tests/conf.py - work on python3-support

2015-03-29  Tobias Brox  <t-caldav@tobixen.no>
	* caldav/objects.py - work on iCloud support.  Solves issue #38,
	read-only access to iCloud seems to work.  Writing still fails,
	ref issue #40.

2015-03-19  Tobias Brox  <t-caldav@tobixen.no>
	* tests/conf.py - ignore ImportError when importing conf_private,
	but not other exceptions.  This way conf_private will be ignored
	if it doesn't exist, but if there are syntax error, nosetest should
	bark.

2015-03-15  Tobias Brox  <t-caldav@tobixen.no>
	* caldav/lib/python_utilities.py - fixing broken charset

2015-02-26  Jack Laxson  <jackjrabbit@gmail.com>
	* setup.py - remove sphinx from install_requires as it is huge and only used
	for generating the documentation.

2015-02-23  Luke  <github@woydziak.com>
	* Interceptable logging

2015-02-16  Luke  <github@woydziak.com>
	* python3 support

2015-02-14  Tobias Brox <t-caldav@tobixen.no>
	* tests/test_caldav.py - new test that deletes events

2015-01-24  Tobias Brox <t-caldav@tobixen.no>
	* caldav/davclient.py - support for digest auth and self-signed
	SSL certs, re issue #26 and #34.
	* tests/test_caldav.py - more generic URL checks to discover
	owncloud and baikal servers.

2015-01-21  Tobias Brox <t-caldav@tobixen.no>
	* caldav/lib/url.py - workaround: "unauth"-method added port
	":None" if no port were given.

2015-01-19  Tobias Brox <t-caldav@tobixen.no>
	* caldav/lib/url.py - added method strip_trailing_slash
	* caldav/objects.py - test breakages on several server
	implementations after the trailing slashes were removed.  Made a
	workaround, though this issue should be investigated better.

2014-05-27  Christian Roeder <christian.roeder@red-hood.de>
	* caldav/davclient.py - RFC compliance fix; Use capitalised Depth:
	Header

2014-05-27  Tobias Brox <t-caldav@tobixen.no>
	* caldav/lib/url.py - Workaround for Zimbra; Zimbra generates
	non-ascii URLs when using non-ascii characters in the calendar
	name, hence the URL library must accept non-ascii characters.

2014-05-27  Tobias Brox <t-caldav@tobixen.no>
	* setup.py - include the requests library dependency

2014-05-20  Christian Roeder <christian.roeder@red-hood.de>
	* caldav/lib/url.py - Do not remove trailing slashes of all URLs.
	According to the RFC, all collection URLs should end with a
	trailing slash, though most caldav server implementations will
	handle URLs with and without trailing slashes the same.

2014-05-11  Abdul Rehman Gani <abdulg@gmail.com>
	* caldav/davclient.py - Change to use the requests library. Fixes
	several compatibility-issues, i.e. with iCloud a get_properties
	call would fail with a Path Handling exception. Happens when
	httplib specifies the netloc in the HTTP request, and the returned
	xml has the base path equal to that netloc instead of the path.

2014-04-13  Abdul Rehman Gani <abdulg@gmail.com>
	* caldav/davclient.py - Removed extraneous parameter passed to
	getresponse(); bugfix in a section not covered by test code

2014-03-14  Tobias Brox <t-caldav@tobixen.no>
	* General - more verbose documentation

	* caldav/test_caldav.py - added an exception for OwnCloud, it does
	not support open-ended date searches

	* setup.py - version bump (0.2.2)

	* caldav/lib/url.py - battle hardening

	* caldav/objects.py - allowing for relative URLs to be used

	* caldav/test_caldav.py - test that relative URLs works as expected

	* caldav/test_caldav.py - test that the URL library is robust

2014-03-07  Tobias Brox <t-caldav@tobixen.no>
	* caldav/davclient.py - minor api difference; it feels more
	object-oriented to write principal = client.principal() than
	principal = Principal(client)

	* caldav/tests/test_caldav.py - work to reflect the above

	* docs/source/index.rst - work to reflect the above

	* docs/source/index.rst - added documentation that the tests may
	fail if several test runs are performed simultaneously

	* caldav/davclient.py - support for unicode and utf8

	* caldav/lib/url.py - support for unicode and utf8

	* caldav/objects.py - minor doc enhancement

	* tests/test_caldav.py - test utf8 and unicode

	* docs/source/index.rst - documentation on how to run the test
	suite towards private calendar servers

	* setup.py - version bump (0.2.1)

2014-03-01  Tobias Brox <t-caldav@tobixen.no>
	* caldav/lib/url.py (make): function for backward compatibility

	* tests/: more test code, including backward compatibility test

2014-02-16  Tobias Brox <t-caldav@tobixen.no>
	* caldav/lib/namespace.py: fixing issue
	https://bitbucket.org/cyrilrbt/caldav/issue/29/centos59-minifix

2013-12-12  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py (Calendar): compatibility hack for zimbra -
	gotcha!  Use Calendar display name in the Calendar URL instead of
	Calendar ID.

	* caldav/objects.py: internal change - _create method now returns
	nothing, but sets self.url and self.id instead.

2013-12-11  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py (DAVObject): convenience fix - made client a
	conditional parameter to __init__.  Defaults to parent.client if
	parent is given.

	* caldav/objects.py (Calendar): convenience fix - made methods
	Calendar.event_by_uid and Calendar.event_by_url.  Calendar.event
	is an alias to Calendar.event_by_uid for backwards compatibility.
	Those methods also loads the object from the remote server (hmmm
	... does that make sense, it's inconsistent with the
	CalendarSet.calendar method)

	* caldav/objects.py (Event): a potential compatibility fix - when
	creating an event, some servers seems to want the uid to match the
	URL (zimbra will yield 302 on the PUT request).  However, I wasn't
	able to GET the event from zimbra, neither before nor after this
	fix :-(

	* caldav/elements/cdav.py: compatibility fix - collation
	"i; octet" (with whitespace) not recognized by baikal.  "i;octet"
	(without whitespace) is OK.

2013-12-08  Tobias Brox <t-caldav@tobixen.no>
	* caldav/objects.py (Calendar): Convenience fix: method add_event
	for making it easier to add events.  Better error handling; if
	calendar creation succeeds but setting calendar name fails, delete
	the calendar before raising the exception.

	* caldav/objects.py (Event): Bugfix for zimbra - 302 is now an
	acceptable return code when creating a new event.

2013-12-07  Tobias Brox <t-caldav@tobixen.no>
	* caldav/davclient.py (DAVClient.request, DAVResponse): Full HTTP
	communication is now available in debug logs

	* caldav/davclient.py (DAVClient.__init__): Username and password
	can now (optionally) be given as separate parameters instead of as
	a part of the configuration URL

	* caldav/objects.py: By now it's sufficient to pass the base URL
	while initializing the DAVClient object.  The library will find
	the principal URL and home calendar set URL through GETPROP

	* caldav/objects.py (Calendar): workaround for problem that
	calendar name didn't get set on some (all?) caldav servers.

	* caldav/objects.py (Principal, CalendarSet): created a method
	calendar() to make it easier to generate a calendar object
	(without server-side communication), and make_calendar for
	creating a new calendar at the server side.

	* tests/test_caldav.py: all broken tests have been disabled.
	Temporary made smaller tests to demonstrate what is actually
	working on all caldav servers I've tested against (Zimbra,
	DAViCal, Baikal and SoGo).

	* caldav/objects.py (DAVObject): (internal change) set __str__ and
	__repr__ to make debugging easier

	* caldav/objects.py: (internal change) Since the principal path and the calendar
	home set path are different on most CALDav server implementations,
	a new class CalendarSet has been made.

	* caldav/lib/url.py: (internal change) Complete rewrite and
	API-change. internally all URLs are now handled as objects

	* caldav/objects.py (Principal): (internal change) made it
	possible to set principal.calendar_home_set (hardly useful except
	for from the unit testing code).

	* All files: misc minor changes to reflect all the changes above.
