2.5b2 release from the 2.5 series released 2011-10-06

Release information

Release notes:

This is the second beta of the 2.5 series, leading to a 2.5.0 release in February 2012. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins.

This release includes more filtering options for ``bzr log``, idle connections handling for ``bzr serve``, a ``development-colo`` experimental format to flesh out the colocated branches UI, better support for foreign formats, enhancements to the config framework and more.

This release includes all bug fixed in previous series known at the time of this release.

Changelog:

External Compatibility Breaks
*****************************

None

New Features
************

* A new ``-O`` standard option (common to all commands) have been added. It
  provides a value for a config option in the ``-Oname=value`` form that
  takes precedence over all definitions found in config files. It can be
  used multiple times to override different options.
  (Vincent Ladeuil, #491196)

* ``bzr log`` now has an option called ``--omit-merges`` to omit
  those commits that merged branches, i.e. those having more than one
  parent.
  In order to avoid confusion, the previous command line option
  ``--include-merges`` has been renamed to ``--include-merged``.
  The old name of the command line option will still be accepted.
  The name change also affects ``bzr missing``.
  (Martin von Gagern)

* ``bzr serve`` will now disconnect clients if they have not issued an RPC
  request after 5minutes. On POSIX platforms, this will also happen for
  ``bzr serve --inet``. This can be overridden with the configuration
  variable ``serve.client_timeout`` or in the command line parameter
  ``bzr serve --client-timeout=X``. Further, it is possible to request
  ``bzr serve [--inet]`` to shutdown gracefully by sending SIGHUP. It will
  finish the current request, and then close the connection.
  (John Arbash Meinel, #824797, #795025)

* The new experimental format ``development-colo`` supports colocated
  branches. This format will eventually be merged back into the ``2a``
  format when it has stabilized and there is adequate UI support for
  colocated branches.
  (Jelmer Vernooij, #831481)

Improvements
************

* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for
every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)

* ``bzr info -v`` can now be run against branches that don't support
``last_revision_info``, in which case the branch information will simply
not be displayed. (Jelmer Vernooij)

Bug Fixes
*********

* ``bzr shelve`` can now be used in emacs shells as the input handling is
turned into a line-based one when ``INSIDE_EMACS`` is set (which is the
case for all recent emacs versions). (Vincent Ladeuil, #856261)

* ``bzr tags`` can now be used against remote repositories that do
not provide access to the revision graph. (Jelmer Vernooij, #858942)

* ``bzr update PATH`` will stop if you seem to be asking it to update
  anything less than a whole tree, because that's not supported by ``bzr``'s
  concept that the whole tree has a single basis revision. Previously, it
  would go ahead and update the whole tree, which was surprising.
  (Martin Pool, #557886)

* Don't crash if ``bzrlib.initialize()`` has not been called while accessing
configs. (Vincent Ladeuil, #863401)

* Redirects between http and https no longer discard path information
in some cases. (Jelmer Vernooij, #853765)

* The ``--overwrite`` argument to ``bzr push`` and ``bzr pull`` no longer
reports all tags as changed. (Jelmer Vernooij, #845396)

* ``WorkingTree.get_file_mtime`` now raises NoSuchId if a file id is
specified that is unknown. (Jelmer Vernooij, #847435)

API Changes
***********

* ``Branch.get_revision_delta`` has been deprecated. Use
``Repository.get_revision_delta`` instead. (Jelmer Vernooij, #859712)

* Plugins that implement custom protocols for ``bzr serve`` should now
  also take an argument ``timeout``. This is used by the the bzr protocol
  to close a connection if a client has been idle for more than X seconds.
  (Default 5minutes). (John Arbash Meinel)

* ``Repository.fileids_altered_by_revision_ids`` has been moved to
``VersionedFileRepository`` and is no longer part of the standard
``Repository`` interface. (Jelmer Vernooij)

* The argument ``include_merges`` to ``missing.find_unmerged`` has
been renamed to ``include_merged``. The old name is still supported
for now but will cause a deprecation warning. (Martin von Gagern)

* The new method ``ControlDirFormat.is_initializable()`` returns a boolean
  indicating whether or not it is possible to use any of the
  initialization methods of that format to create a new control dir.
  (Jelmer Vernooij)

Internals
*********

* ``Branch`` objects can now use a config stack with the newly introduced
  ``get_config_stack()``. Both ``get_config`` and ``get_config_stack`` can
  be used for the same branch but it's recommended to stick to one for a
  given option.

Testing
*******

* Test scripts can now use ``bzr shelve`` and provide their input as
complete lines. (Vincent Ladeuil, #856261)

* Really corrupt the pack file without depending on a special length or value.
(Vincent Ladeuil, #807032)

2.5b1 release from the 2.5 series released 2011-09-15

Release information

Release notes:

This is the first beta of the 2.5 series, leading up to a 2.5.0 release in February 2012. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins. Some plugins may need small updates to work with 2.5b1.

Changelog:

External Compatibility Breaks
*****************************

None

New Features
************

* A ``from_unicode`` parameter can be specified when registering a config
  option. This implements boolean, integer and list config options when the
  provided ``bool_from_store``, ``int_from_store`` and ``list_from_store``
  are used for this parameter. (Vincent Ladeuil)

* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
  checks to see if the most recent published source package version for
  that project is present in the branch tags. This should help developers
  trust whether the packaging branch is up-to-date and can be used for new
  changes. The level of verbosity is controlled by the config item
  ``launchpad.packaging_verbosity``. It can be set to one of

off
disable all checks

minimal
only display if the branch is out-of-date

short
also display single-line up-to-date and missing,

all
(default) display multi-line content for all states

(John Arbash Meinel, #609187, #812928)

* Add a config option gpg_signing_key for setting which GPG key should
  be used to sign commits. Also default to using the gpg user identity
  which matches user_email() as set by whoami.
  (Jonathan Riddell, #68501)

* An ``invalid`` parameter can be specified when registering a config option
  to decide what should be done when invalid values are
  encountered. 'warning' and 'error' will respectively emit a warning and
  ignore the value or errors out. (Vincent Ladeuil)

* bzr add now skips large files in recursive mode. The default "large"
  size is 20MB, and is configurable via the add.maximum_file_size
  option. A value of 0 disables skipping. Named items passed to add are
  never skipped. (Shannon Weyrick, #54624)

* ``bzr help configuration/<option>`` display the help for ``option`` for
all registered configuration options. (Vincent Ladeuil, #747050)

* ``bzr log -m`` now matches message, author, committer and bugs instead
  of just matching the message. ``--message`` keeps its original meaning,
  while ``--match-message, --match-author, --match-committer`` and
  ``--match-bugs`` match each of those fields. (Jacek Sieka)

* ``config.Option`` can now declare ``default_from_env``, a list of
environment variables to get a default value from. (Vincent Ladeuil)

* ``config.NameMatcher`` can be used to implement config stores and stacks
that need to provide specific option values for arbitrary unique IDs (svn
repository UUIDs, etc). (Vincent Ladeuil, #843638)

* New builtin ``bzr branches`` command, which lists all colocated branches
in a directory. (Jelmer Vernooij, #826820)

* Relative local paths can now be specified in URL syntax by using the
"file:" prefix. (Jelmer Vernooij)

* Report commits signed with expired keys in ``verify-signatures``.
(Jonathan Riddell, #804254)

* Translations are now enabled for command help, errors and globally
for any message using gettext given on output. (Jonathan Riddell,
INADA Naoki, #83941)

Improvements
************

* ``bzr add`` will now warn about nested subtrees that are skipped.
(Jelmer Vernooij, #187342)

* ``bzr commit -m ''`` can now be used to force an empty commit message.
Entering an empty commit message in the message editor still triggers
an error. (Jelmer Vernooij)

* ``bzr pull`` will now mention how many tags it has updated.
(Jelmer Vernooij, #164450)

* ``bzr tag`` no longer errors if a tag already exists but refers to the
same revision, and will mention when a tag has been updated
rather than created. (Jelmer Vernooij, #381203)

* ``bzr uncommit`` will now remove tags that refer to removed revisions.
The ``--keep-tags`` option can be used to prevent this behaviour.
(Jelmer Vernooij, #605814)

* Do not run i18n initialisation twice. (Jonathan Riddell)

* Install translation .mo files. (Jonathan Riddell)

* Locations printed by ``bzr upgrade`` are now formatted before display.
(Jelmer Vernooij)

* ``Repository.get_parent_map`` now estimates the size of the returned
  content more accurately. This means that we get closer to the desired
  64kB/request. For repositories converted from svn, this can be an
  improvement of approx 5:1 in round trips to discover the whole history.
  (John Arbash Meinel)

* Support a ``bugtracker`` option which is used by ``bzr commit --fixes``
if no bug tracker was specified on the command line.
(Jelmer Vernooij, #334860)

* Use gettext.NullTranslations in i18n to allow use of i18n even when
translations are not turned on. (Jonathan Riddell)

Bug Fixes
*********

* ``bzr commit`` now correctly reports missing files as "removed", not
"modified". (Jelmer Vernooij, #553955)

* ``bzr reconfigure`` will now allow multiple non-conflicting requests
in a single invocation, e.g. ``--branch`` and ``--use-shared``.
(Martin von Gagern, #842993)

* A call to CHKInventory's filter-method will not result in a
  DuplicateFileId error, if you move a subfolder and change a file in
  that subfolder.
  (Bastian Bowe, #809901)

* Branching from a stacked branch no longer does a ``get_parent_map``
  request for each revisions that is in the stacked-on repository while
  determining what revisions need to be fetched. This mostly impacts
  branching initialy into an empty shared repository when the source is
  not the development focus. (John Arbash Meinel, #388269)

* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode
errors. (Vincent Ladeuil, #822571)

* Fix fallout from URL handling changes in 2.5 that caused an IndexError to be
raised whenever a transport at the drive root was opened on windows.
(Martin [gz], #841322)

* Fixed loading of external merge tools from config to properly decode
command-lines which contain embedded quotes. (Gordon Tyler, #828803)

* Rather than an error being raised, a warning is now printed when the
current user does not have permission to read a configuration file.
(Jelmer Vernooij, #837324)

* The pull command will now always use separate connections for the
  case where the destination is a heavyweight checkout of some remote
  branch on the same host as the source branch.
  (Martin von Gagern, #483661)

* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so
operations that use it, like merge, can now create trees without a root.
(Aaron Bentley)

Documentation
*************

* Release instructions refreshed. (Vincent Ladeuil)

API Changes
***********

* ``BranchFormat.initialize`` now takes a ``append_revisions_only``
argument. (Jelmer Vernooij)

* ``Branch._get_checkout_format`` now takes a ``lightweight`` argument
which indicates if the format should be for a lightweight or a
heavyweight checkout. (Jelmer Vernooij)

* ``ControlDir.create_branch`` now takes a ``append_revisions_only`` argument.
(Jelmer Vernooij)

* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs.
(Jelmer Vernooij)

* New method ``Config.get_user_option_as_int_from_SI`` added for expanding a
value in SI format (i.e. "20MB", "1GB") into its integer equivalent.
(Shannon Weyrick)

* New method ``InterTree.file_content_matches`` which checks that
two files in different trees have the same contents.
(Jelmer Vernooij)

* New method ``Tree.get_file_verifier`` which allows tree implementations
to return non-sha1 checksums to verify files.
(Jelmer Vernooij, #720831)

* New methods ``get_transport_from_path`` and ``get_transport_from_url``
have been added that only support opening from a path or a URL,
unlike ``get_transport``. (Jelmer Vernooij)

* New registry ``OptionRegistry`` specialized for configuration options.
(Vincent Ladeuil)

* Remove ``AtomicFile.closed`` which has been deprecated in bzr 0.10.
(Vincent Ladeuil)

* Remove ``commands._builtin_commands``, ``commands.shlex_split_unicode``,
``Command._maybe_expand_globs`` and ``Command.run_direct`` deprecated in
2.10 and 2.2.0. (Vincent Ladeuil)

* Remove ``diff.get_trees_and_branches_to_diff`` deprecated in 2.2.0.

* Remove ``log.calculate_view_revisions``, ``log._filter_revision_range``,
  ``log.get_view_revisions`` which have been deprecated in bzr 2.1.0. Also
  remove ``log.show_one_log`` which was never properly deprecated but wasn't
  used and is easy to inline if needed. (Vincent Ladeuil)

* Remove ``trace.info``, ``trace.error`` and ``trace.show_log_error``
deprecated in 2.1.0. (Vincent Ladeuil)

* Remove ``TransportListRegistry.set_default_transport``, as the concept of
a default transport is currently unused. (Jelmer Vernooij)

* Remove ``UIFactory.warn_cross_format_fetch`` and
``UIFactory.warn_experimental_format_fetch`` in favor of
``UIFactory.show_user_warning``. (Jelmer Vernooij)

* ``Tags`` containers can now declare whether they support versioned
tags and whether tags can refer to ghost tags.
(Jelmer Vernooij)

* ``Tags.merge_to`` now returns a dictionary with the updated tags
and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)

* There is a new class `ContentFilterTree` that provides a facade for
  content filtering. The `filtered` parameter to `export` is deprecated
  in favor of passing a filtered tree, and the specific exporter plugins
  no longer support it.
  (Martin Pool)

* ``Transport`` now has a ``_parsed_url`` attribute instead of
  separate ``_user``, ``_password``, ``_port``, ``_scheme``, ``_host``
  and ``_path`` attributes. Proxies are provided for the moment but
  may be removed in the future. (Jelmer Vernooij)

Internals
*********

* A new debug flag ``hpss_client_no_vfs`` will now cause the HPSS client
to raise a ``HpssVfsRequestNotAllowed`` exception when a VFS request
is attempted. (Jelmer Vernooij)

* New method ``ControlDir._get_selected_branch`` which returns the
colocated branch selected using path segment parameters.
(Jelmer Vernooij, #380871)

Testing
*******

* Blackbox tests (including test scripts) can be debugged interactively (see
bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)

* `BranchBuilder.build_snapshot` now supports a "flush" action. This
  cleanly and reliably allows tests using `BranchBuilder` to construct
  branches that e.g. rename files out of a directory and unversion that
  directory in the same revision. Previously some changes were impossible
  due to the order that `build_snapshot` performs its actions.
  (Andrew Bennetts)

* Don't require ``os.fdatasync`` to be defined on all supported OSes
(BSD-based OSes don't define it). (Vincent Ladeuil, #822649)

* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)

* ``LockDir`` can now be run when the local hostname is ``localhost``.
(Jelmer Vernooij, #825994)

* ``ModuleAvailableFeature`` won't try to import already imported modules,
allowing it to be used for modules with side-effects.
(Vincent Ladeuil, #712474)

* Output time stamps while running ``make check`` to get better timings from
pqm. (Vincent Ladeuil, #837926)

* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
  just compares the bytes in the dirstate file to its pristine state,
  rather than opening the WorkingTree and calling ``last_revision()``.
  This reduces the overall test suite time by about 10% on my laptop.
  (Andrew Bennetts)

* Update `TestCase.knownFailure` to the testtools way of handling expected
failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)

2.4.2 release from the 2.4 series released 2011-10-27

Release information

Release notes:

This is a bugfix release. Most of the bugs dealt with portability issues. Upgrading is recommended for all users of earlier 2.4 releases.

Changelog:

Improvements
************

* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for
every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)

Bug Fixes
*********

* Fixed an infinite loop when creating a repo at the root of the filesystem,
  i.e. "/", due to posixpath.normpath() not collapsing 2 leading slashes into
  one, thus respecting the POSIX standard, but making relpath() loop infinitely.
  (Florian Vichot, #861008)

* Fixed loading of external merge tools from config to properly decode
command-lines which contain embedded quotes. (Gordon Tyler, #828803)

* Include declaration of 'changed' to avoid an UnboundLocalError in dirstate
pyrex code with new Cython versions. (Denys Duchier, #837221)

* Prevent several kinds of OverflowError and other fallout from failing to fit
stat fields into four bytes in dirstate pack_stat implementations.
(Martin Packman, #683191 #706957)

* Return early from create_delta_index_from_delta given tiny inputs. This
avoids raising a spurious MemoryError on certain platforms such as AIX.
(John Arbash Meinel, #856731)

Documentation
*************

* Corrected documentation for ``bzr serve`` in the Admin Guide.
(Morten Bøgeskov, Martin Pool, #832576)

API Changes
***********

None.

Internals
*********

No changes.

Testing
*******

* Accept both old and new style testtools output in selftest tests.
(Jelmer Vernooij, Martin Packman, #815423)

* Fix the race for TestingThreadingTCPServer in
test_server_crash_while_responding. (Vincent Ladeuil, #869366)

* Really corrupt the pack file without depending on a special length or value.

(John Arbash Meinel, #837293)

* Fix i18n use when no environment variables are set. (Jelmer Vernooij, #810701)

* Avoid UnicodeDecode error when reporting EINVAL from transports.
(IWATA Hidetaka, #829237)

Documentation

2.4.0 (Oronsay) release from the 2.4 series released 2011-08-11

Release information

Release notes:

This release marks the start of a new long-term-stable series. From here, we
will only make bugfix releases on the 2.4 series (2.4.1, etc, and support it
until February 2013), while 2.5 will become our new development series.

This is a bugfix and polish release over the 2.3 series, with a large number
of bugs fixed (>150 for the 2.4 series alone), and some performance
improvements. Support for python 2.4 and 2.5 has been dropped, many large
working tree operations have been optimized as well as some stacked branches
operations.

Only bugfixes from other stables series have been included since 2.4b5 so
all known fixed bugs are included here.

Users are encouraged to upgrade from the other stable series.

Changelog:

Bug Fixes
*********

* A call to CHKInventory's filter-method will not result in a
  DuplicateFileId error, if you move a subfolder and change a file in
  that subfolder.
  (Bastian Bowe, #809901)

off
disable all checks

minimal
only display if the branch is out-of-date

short
also display single-line up-to-date and missing,

all
(default) display multi-line content for all states

(John Arbash Meinel, #609187, #812928)

* Cope with not all Python versions having a ``clear`` method on
``TestCase._type_equality_funcs``.
(Martin [gz], Jelmer Vernooij, #809048)

* Fetching tags when fetching the tip revision of a branch is now
  controlled by the config setting ``branch.fetch_tags``. The behavior has
  been reverted to 2.3's not-fetching tagged revisions by default.
  (John Arbash Meinel, #771184)

* The fix for bug #513709 caused us to open a new connection when
  switching a lightweight checkout that was pointing at a bound branch.
  This isn't necessary because we know the master URL without opening it,
  avoiding an extra SSH connection, etc.

2.4b5 release from the 2.4 series released 2011-07-07

Release information

Release notes:

This is the fifth (and last) beta of the 2.4 series leading to 2.4.0 release in Auguest 2011. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins.

This release includes all bug fixed in previous series known at the time of this release.

Changelog:

External Compatibility Breaks
*****************************

None.

New Features
************

* New command ``verify-signatures`` to check if all commits or specified commits
have digital signatures from trusted keys. Requires python-gpgme to be
installed.

* New option ``--signatures`` for ``bzr log`` to display digital signature
verification results for each commit.

* Config option acceptable_keys to list which GPG keys are verified as trusted.

* Config option validate_signatures_in_log to always show signatures in
``bzr log``.

Improvements
************

* ``Branch.open`` is now about 3x faster (about 2ms instead of 6.5ms).
(Andrew Bennetts).

Bug Fixes
*********

* Display a proper error message when a config file content cannot be
decoded as UTF-8 or when it cannot be parsed.
(Vincent Ladeuil, #502060, #688677, #797246)

* Generate a single conflict (instead of two) when merging a branch
modifying and renaming a file in a branch that deleted it (or vice-versa).
(Vincent Ladeuil, #688101)

* Give a more helpful message when the bzr executable doesn't match the
  library. (This typically happens because of a misconfigured PYTHONPATH
  or half-installed bzr.)
  (Martin Pool, #804553)

* Properly load utf8-encoded config files. (Vincent Ladeuil, #799212)

* ``GraphThunkIdsToKeys.merge_sort`` now properly returns
keys rather than ids. (Jelmer Vernooij, #799677)

* ``TreeTransformBase.fixup_new_roots`` can now check that a tree root
is present. (Jelmer Vernooij, #801257)

API Changes
***********

* New attributes ``WorkingTreeFormat.supports_versioned_directories`` and
``RepositoryFormat.supports_versioned_directories``.
(Jelmer Vernooij, #765815)

* The "revno" field type when using the python version-info format is now
a string (to handle dotted revnos) (Benoît Pierre, #796259)

Internals
*********

* Start implementing localization, starting with command help text (but not
the command options themselves). This will allow bootstrapping the bzr
internationalization process. (Inada Naoki)

Testing
*******

* Fix test failures when running as a homeless user (debian buildd). Tests
leaking into ``${HOME}/.bzr.log`` should be detected properly now.
(Vincent Ladeuil, #798698)

2.4b4 release from the 2.4 series released 2011-06-16

Release information

Release notes:

This is the fourth beta of the 2.4 series, leading to a 2.4.0 release in
August 2011. Beta releases are suitable for everyday use but may cause some
incompatibilities with plugins.

This release includes all bug fixed in previous series known at the time of
this release.

Changelog:

External Compatibility Breaks
*****************************

* Do not treat configuration option 'check_signatures = require' as if
it were 'create_signatures = always' (Jonathan Riddell)

New Features
************

* Hooks have been added for config stacks: ``get``, ``set`` and ``remove``
  are called when an option is repsectively read, modified or deleted. Also
  added ``load`` and ``save`` hooks for config stores, called when the
  stores are loaded or saved. (Vincent Ladeuil)

* New hook server_exception in bzrlib.smart.server to catch any
exception caused while running bzr serve.
(Jonathan Riddell, #274578)

* New hook set_commit_message in bzrlib.msgeditor to set
a commit message and revision properties. (Jonathan Riddell,
#274578)

* Support ``-S`` as an alias for ``--short`` for the ``log`` and
``missing`` commands. (Martin von Gagern, #38655)

Improvements
************

* ``bzr annotate`` can be run without setting whoami data first. (Jonathan
Riddell, #667408)

Bug Fixes
*********

* Bazaar can now detect when a lock file is held by a dead process
  originating from the same machine, and steal the lock after printing a
  message to the user. This is off by default, for safety, but can be
  turned on by setting the configuration variable ``locks.steal_dead`` to
  ``True``.
  (Martin Pool, #220464)

* Credentials in the log output produced by ``-Dhttp`` are masked so users
can more freely post them in bug reports. (Vincent Ladeuil, #723074)

* Fix a race condition for ``server_started`` hooks leading to a spurious
test failure. (Vincent Ladeuil, #789167)

* Fix exporting subdirectory with ``--per-file-timestamps``.
(Szilveszter Farkas, #795557)

* Handle files that get created but don't get used during TreeTransform.
  ``open()`` can create a file, and still raise an exception before it
  returns. So anything we might have created, make sure we destroy during
  ``finalize()``. (Martin [gz], #597686)

* ``pack_repo`` now uses ``Transport.move`` instead of
``Transport.rename``, deleting any existing targets even on SFTP.
(Martin von Gagern, #421776)

* Pass the ``build_mo`` command to the rest of the setup() calls in
  setup.py. The ``bdist_wininst`` and ``py2exe`` code paths were failing
  because ``build_mo`` became a required step that they didn't know about.
  (John Arbash Meinel, #787122)

* Properly avoid re-adding a file after it changes case on CICP
filesystems. (John Arbash Meinel, #798130)

* Reports the original error when an InvalidHttpResponse exception is
encountered to facilitate debug. (Vincent Ladeuil, #788530)

* Reports a non-existant file error when trying to merge in a file
that does not exist. (Jonathan Riddell, #330063)

* ``UIFactory.prompt``, ``UIFactory.get_username``,
``UIFactory.get_password`` and ``UIFactory.get_boolean`` now require a
unicode prompt to be passed in. (Jelmer Vernooij, #592083)

* Support merging into the empty tree. (Aaron Bentley, #595328)

Documentation
*************

* Improve documentation of ``bzr merge --force``.
(Neil Martinsen-Burrell, #767307)

* Make docs for configuration options for digital signatures match
reality. (Jonathan Riddell)

* Add user-guide page on GPG signatures. (Jonathan Riddell)

API Changes
***********

* Information about held lockdir locks returned from eg `LockDir.peek` is
  now represented as a `LockHeldInfo` object, rather than a plain
  Python dict.
  (Martin Pool)

* Remove `file_status` function.
(Martin Pool)

* ``Repository.iter_reverse_revision_history`` is now deprecated.
Use ``Graph.iter_lefthand_ancestry`` instead.
(Jelmer Vernooij, #739481)

Internals
*********

* ``tools/check-newsbugs.py`` accepts a ``--browser`` option to open
corresponding launchpad pages in a browser. (Vincent Ladeuil)

Testing
*******

* A `ImportTariffTestCase` base class has been added in
``bzrlib.tests.test_import_tariff``, which can be used for import tariff
tests in plugins. (Jelmer Vernooij, #793465)

* Fix deadlock in `TestImportTariffs.test_simple_serve` when stderr gets
  more output than fits in the default buffer. This was happening on the
  Windows buildslave, and could easily happen in other circumstances where
  the default OS buffer size for pipes is small or the ``python -v``
  output is large. (Andrew Bennetts, #784802)

* Fix spurious test failure on OSX for WorkingTreeFormat2.
(Vincent Ladeuil, #787942)

* Re-target ``bb.test_merge.TestMerge.test_merge_reversed_revision_range``
and rewrite it as a parameterized test to avoid unrelated failures.
(Vincent Ladeuil, #795456)

* Show log file contents from subprocesses started by
`start_bzr_subprocess` in test failure details. This may help diagnose
strange hangs and failures involving subprocesses. (Andrew Bennetts)

* Skip ``utextwrap`` tests when ``sphinx`` breaks text_wrap by an hostile
monkeypatch to textwrap.TextWrapper.wordsep_re.
(Vincent Ladeuil, #785098)

* Multiple ``selftest --exclude`` options are now combined instead of
overriding each other. (Vincent Ladeuil, #746991)

* Restore some ``FTPTransport`` test coverage by allowing ``pyftpdlib
  0.6.0`` to be used. Also restore ``medusa`` support while leaving it
  disabled to make it easier to use if/when we can in the future.
  (Vincent Ladeuil, #781140)

* `TestImportTariffs` no longer uses the real ``$HOME``. This prevents it
  from polluting ``$HOME/.bzr.log`` or being accidentally influenced by
  user configuration such as aliases. It still runs with all the user's
  plugins enabled, as intended.
  (Vincent Ladeuil, Andrew Bennetts, #789505)

2.4b3 release from the 2.4 series released 2011-05-26

Release information

Release notes:

This is the third beta of the 2.4 series, leading to a 2.4.0 release in
August 2011. Beta releases are suitable for everyday use but may cause some
incompatibilities with plugins.

This release includes all bug fixed in previous series known at the time of
this release.

Changelog:

External Compatibility Breaks
*****************************

* ``bzr-2.4`` has officially dropped support for python2.4 and python2.5.
We will continue to maintain ``bzr-2.3`` for people who still need to
use those versions of python. (John Arbash Meinel)

New Features
************

* The text compressor used for 2a repositories now has a tweakable
  parameter that can be set in bazaar.conf.
  ``bzr.groupcompress.max_entries_per_source`` default of 65536.
  When doing compression, we build up an index of locations to match
  against. Setting this higher will result in slightly better compression,
  at a cost of more memory. Note that a value of 65k represents fully
  sampling a 1MB file. So this only has an effect when compressing texts
  larger than N*16 bytes. (John Arbash Meinel, #602614)

Improvements
************

* ``bzr branch --stacked`` from a smart server uses the network a little
more efficiently. For a simple branch it reduces the number of
round-trips by about 20%. (Andrew Bennetts)

* ``bzr log --line`` scales the width of the author field with the size of
the line. This means that the full author name is shown when the
environment variable BZR_COLUMNS=0. (Neil Martinsen-Burrell)

* ``bzr pull`` now properly triggers the fast
  ``CHKInventory.iter_changes`` rather than the slow generic
  inter-Inventory changes. It used to use a ``DirStateRevisionTree`` as
  one of the source trees, which is faster when we have to read the whole
  inventory anyway, but much slower when we can get just the delta out of
  the repository. On a 70k record tree, this changes ``bzr pull`` from 28s
  down to 17s. (John Arbash Meinel, #780677)

* Slightly reduced memory consumption when fetching into a 2a repository
by reusing existing caching a little better. (Andrew Bennetts)

* Speed up ``bzr status`` by a little bit when there are a couple of
  modified files. We now track how many files we have seen that need
  updating, and only rewrite the dirstate file if enough of them have
  changed. The default is 10, and can be overridden by setting the branch
  option "``bzr.workingtree.worth_saving_limit``".
  (Ian Clatworthy, John Arbash Meinel, #380202)

* Speed up ``bzr uncommit``. Instead of resetting the dirstate from
scratch, use ``update_basis_by_delta``, computing the delta from the
repository. (John Arbash Meinel, #780544)

Bug Fixes
*********

* All Tree types can now be exported as tar.*, zip or directories.
(Aaron Bentley)

* ``bzr merge --no-remember location`` never sets ``submit_branch``.
(Vincent Ladeuil, #782169)

* ``bzr pull --no-remember location`` never sets
  ``parent_location``. ``bzr push --no-remember location`` never
  sets ``push_location``. ``bzr send --no-remember
  submit_location public_location`` never sets ``submit_branch``
  nor ``public_branch``. (Vincent Ladeuil)

* Conflicts involving non-ascii filenames are now properly reported rather
than failing with a UnicodeEncodeError. (Martin [GZ], #686161)

* Correct parent is now set when using 'switch -b' with bound branches.
(A. S. Budden, #513709)

* Fix `bzr plugins` regression in bzr 2.4 which resulted in a traceback
from writelines on ckj terminals. (Martin [GZ], #754082)

* ``WT.inventory`` and ``WT.iter_entries_by_dir()`` was not correctly
reporting subdirectories that were tree references (in formats that
supported them). (John Arbash Meinel, #764677)

* Merging into empty branches now gives an error as this is currently
not supported. (Jonathan Riddell, #242175)

* Do not show exception to user on pointless commit error (Jonathan
Riddell #317357)

* ``WT.update_basis_by_delta`` no longer requires that the deltas match
  the current WT state. This allows ``update_basis_by_delta`` to be used
  by more commands than just commit. Updating with a delta allows us to
  not load the whole inventory, which can take 10+s with large trees.
  (Jonathan Riddell, John Arbash Meinel, #781168)

Documentation
*************

* Restore the workaround for option names including dots (--1.14) which was
disabled when we stopped listing --1.9 as a format.
(Vincent Ladeuil, #782289)

API Changes
***********

* ``annotate_file`` has been deprecated in favor of
``annotate_file_revision_tree``. (Jelmer Vernooij, #775598)

* ``Branch.fetch`` now takes an optional ``limit`` argument.
(Andrew Bennetts, Jelmer Vernooij, #750175)

* ``Inter.get`` now raises ``NoCompatibleInter`` if there are no
compatible optimisers rather than an instance of the class it is called
on. (Jelmer Vernooij)

* ``Branch.push`` now takes a ``lossy`` argument.
``Branch.lossy_push`` has been removed.
(Jelmer Vernooij)

* New method ``Repository.get_file_graph`` which can return the
per-file revision graph. (Jelmer Vernooij, #775578)

* The default implementation of ``Branch`` is now oriented to
  storing the branch tip. Branch implementations which store the full
  history should now subclass ``FullHistoryBzrBranch``.
  ``Branch._last_revision_info`` has been renamed to
  ``Branch._read_last_revision_info`` (Jelmer Vernooij)

* ``Tree.__iter__`` has been deprecated; use ``Tree.all_file_ids``
instead. (Jelmer Vernooij)

* ``Tree.get_symlink_target`` now takes an optional ``path``
argument. (Jelmer Vernooij)

Internals
*********

* Removed ``bzrlib.branch._run_with_write_locked_target`` as
``bzrlib.cleanup`` provides the same functionality in a more general
way. (Andrew Bennetts)

Testing
*******

* A test that was expected to fail but passes instead now counts as a failure
catching up with new testtools and subunit handling. (Martin [GZ], #654474)

* Make it easier for plugins to reuse the per_workingtree scenarios by
restoring the wt_scenarios helper that was accidentally deleted.
(Vincent Ladeuil, #783472)

* Removed ``test_breakin`` tests that were excessively prone to hanging,
did not work on Wine, and partly already disabled.
(Martin Pool, #408814, #746985)

* Windows locations are different and should be tested accordingly.
(Vincent Ladeuil, #788131)

2.4b2 release from the 2.4 series released 2011-04-28

Release information

Release notes:

This is the second beta of the 2.4 series, leading to a 2.4.0 release in
August 2011. Beta releases are suitable for everyday use but may cause some
incompatibilities with plugins.

This release includes all bug fixed in previous series known at the time of
this release.

Changelog:

External Compatibility Breaks
*****************************

* Two command synonyms for ``bzr branch`` have been deprecated, to avoid
confusion and to allow the names to later be reused. The removed names
are: ``get`` and ``clone``. (Martin Pool, #506265)

New Features
************

* ``bzr commit`` now supports a ``--lossy`` argument that can be used
to discard any data that can not be natively represented when committing
to a foreign VCS. (Jelmer Vernooij, #587721)

Improvements
************

* ``bzr merge`` in large trees is now significantly faster. On a 70k entry
tree, the time went from ~3min down to 30s.
(John Arbash Meinel, #759091)

* Resolve ``lp:FOO`` urls locally rather than doing an XMLRPC request if
  the user has done ``bzr launchpad-login``. The bzr+ssh URLs were already
  being handed off to the remote server anyway (xmlrpc has been mapping
  ``lp:bzr`` to ``bzr+ssh://bazaar.launchpad.net/+branch/bzr``, rather
  than ``bzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev`` for a few
  months now.) By doing it ourselves, we can cut out substantial startup
  time. From Netherlands to London it was taking 368ms to do the XMLRPC
  call as much as 2s from Sydney. You can test the local logic by using
  ``-Dlaunchpad``. (John Arbash Meinel, #397739)

* When building a new WorkingTree (such as during ``bzr co`` or
  ``bzr branch``) we now properly store the stat and hash of files that
  are old enough. This saves a fair amount of time on the first
  ``bzr status`` (on a 500MB tree, it saves about 30+s).
  (John Arbash Meinel, #740932)

Bug Fixes
*********

* Arguments that can't be decoded to unicode in the current posix locale give
a clearer error message without a traceback. (Martin [gz], #745712)

* ``bzrlib.log._DEFAULT_REQUEST_PARAMS`` is no longer accidentally
  mutated by ``bzrlib.log._apply_log_request_defaults``. In practice
  these default values aren't relied on very often so this probably
  wasn't causing any trouble. (Andrew Bennetts)

* ``bzr log`` now works on revisions which are not in the current branch.
(Matt Giuca, #241998)

* Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)

* ``bzrlib.merge.Merge`` now calls ``iter_changes`` without
  ``include_unversioned=True``. This makes it significantly faster in many
  cases, because it only looks at modified files, rather than building
  information about all files. This can cause failures in other
  TreeTransform code, because it had been expecting to know the names of
  things which had not changed (such as parent directories). All cases we
  know about so far have been fixed, but there may be fallout for edge
  cases that we are missing. (John Arbash Meinel, #759091)

* Standalone bzr.exe installation on Windows: user can put additional python
  libraries into ``site-packages`` subdirectory of the installation directory,
  this might be required for "installing" extra dependencies for some plugins.
  (Alexander Belchenko, #743256)

* ``TreeTransform.create_file/new_file`` can now take an optional ``sha1``
  parameter. If supplied, when the transform is applied, it will then call
  ``self._tree._observed_sha1`` for those files. This lets us update the
  hash-cache for content that we create, preventing us from re-reading the
  content in the next ``bzr status``. (John Arbash Meinel, #740932)

Documentation
*************

* Added a section about using a shared SSH account on a server for bzr+ssh
access. (Russell Smith)

* The documentation now recommends using SSH rather than SFTP in the
  tutorials and the examples, because that will generally be much faster
  and better in cases where it can be used. SFTP is still available and
  mentioned as an alternative. (Martin Pool, #636712)

API Changes
***********

* Commands now have an `invoked_as` attribute, showing the name under
which they were called before alias expansion.
(Martin Pool)

* ``Hooks.create_hook`` is now deprecated in favour of ``Hooks.add_hook``.
(Jelmer Vernooij)

* If you call `bzrlib.initialize` but forget to enter the resulting object
  as a context manager, bzrlib will now be initialized anyhow.
  (Previously simple programs calling bzrlib might find the library was
  mysteriously silent.)
  (Martin Pool)

* Inventory-specific functionality has been split out of ``Tree`` into
a new ``InventoryTree`` class. Tree instances no longer
necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)

* Inventory-specific functionality has been split out of ``RevisionTree``
into a new ``InventoryRevisionTree`` class. RevisionTree instances no
longer necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)

* New method ``Hooks.uninstall_named_hook``. (Jelmer Vernooij, #301472)

* ``revision_graph_can_have_wrong_parents`` is now an attribute
on ``RepositoryFormat`` rather than a method on ``Repository``.
(Jelmer Vernooij)

* ``Testament`` now takes a ``tree`` rather than an
``inventory``. (Jelmer Vernooij, #762608)

* ``TestCase.failUnlessExists`` and ``failIfExists`` are deprecated in
  favour of ``assertPathExists`` and ``assertPathDoesNotExist``
  respectively.
  (Martin Pool)

* The ``revno`` parameter of ``log.LogRevision`` may now be None,
representing a revision which is not in the current branch.
(Matt Giuca, #241998)

* The various knit pack repository format classes have been moved
from ``bzrlib.repofmt.pack_repo`` to
``bzrlib.repofmt.knitpack_repo``. (Jelmer Vernooij)

* ``RevisionTree`` now has a new method ``get_file_revision``.
(Jelmer Vernooij)

* ``WorkingTree`` no longer provides an ``inventory``. Instead,
  all inventory-related functionality is now on the subclass
  ``InventoryWorkingTree`` that all native Bazaar working tree
  implementations derive from. (Jelmer Vernooij)

Internals
*********

* Added ``osutils.lstat`` and ``osutils.fstat``. These are just the ``os``
  functions on Linux, but they are wrapped on Windows so that fstat
  matches lstat results across all python versions.
  (John Arbash Meinel)

* ``WorkingTree._observed_sha1`` also updates the 'size' column. It
  happened to be updated as a side-effect of commit, but if we start using
  the function elsewhere we might as well do it directly.
  (John Arbash Meinel)

Testing
*******

* Stop using `failIf`, `failUnless`, `failIfEqual`, etc, that give
`PendingDeprecationWarnings` on Python2.7.
(Martin Pool, #760435)

Release information

Release notes:

This is the first beta of the 2.4 series, leading up to a 2.4.0 release in August 2012. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins. Some plugins may need small updates to work with 2.4b1.

2.4b1 includes a new changelog merge plugin, better configuration for external merge tools and some enhanced features for the configuration files.

It also includes bug fixes for 2.0.7, 2.1.4 and 2.2.5 and ~40 fixes of its own so all known fixed bugs are included here.

bzr 2.4b1
#########

:2.4b1: 2011-04-17

This is the first beta of the 2.4 series, leading up to a 2.4.0
release in August 2011. Beta releases are suitable for everyday use
but may cause some incompatibilities with plugins. Some plugins may need
small updates to work with 2.4b1.

External Compatibility Breaks
*****************************

(none)

New Features
************

* Added ``changelog_merge`` plugin for merging changes to ``Changelog`` files
in GNU format. See ``bzr help changelog_merge`` for details.
(Andrew Bennetts)

* Configuration options can now use references to other options in the same
  file by enclosing them with curly brackets (``{other_opt}``). This makes it
  possible to use, for example,
  ``push_location=lp:~vila/bzr/config-{nickname}`` in ``branch.conf`` when
  using a loom. During the beta period, the default behaviour is to disable
  this feature. It can be activated by declaring ``bzr.config.expand = True``
  in ``bazaar.conf``. (Vincent Ladeuil)

* External merge tools can now be configured in bazaar.conf. See
``bzr help configuration`` for more information. (Gordon Tyler, #489915)

* The ``lp:`` directory service now supports Launchpad's QA staging.
(Jelmer Vernooij, #667483)

Improvements
************

* A new hidden command ``bzr repair-workingtree``. This is a way to force
the dirstate file to be rebuilt, rather than using a ``bzr checkout``
workaround. (John Arbash Meinel)

* Added a ``Branch.heads_to_fetch`` RPC to the smart server protocol.
This allows formats from plugins (such as looms) to efficiently tell the
client which revisions need to be fetched. (Andrew Bennetts)

* Branching, merging and pulling a branch now copies revisions named in
tags, not just the tag metadata. (Andrew Bennetts, #309682)

* ``bzr cat-revision`` no longer requires a working tree.
(Jelmer Vernooij, #704405)

* ``bzr export --per-file-timestamps`` for .tar.gz files will now
  override the mtime for trees exported on Python 2.7 and later, which
  expose the 'mtime' field in gzip files. This makes the output of
  ``bzr export --per-file-timestamps`` for a particular tree
  deterministic. (Jelmer Vernooij, #711226)

* ``bzr export --format=zip`` can now export to standard output,
like the other exporters can. (Jelmer Vernooij, #513752)

* ``bzr export`` can now create ``.tar.xz`` and ``.tar.lzma`` files.
(Jelmer Vernooij, #551714)

Bug Fixes
*********

* A MemoryError thrown on the server during a remote operation will now be
usefully reported, and other unexpected errors will include the class name.
(Martin [gz], #722416)

* ``bzr annotate -r-1 file`` will now properly annotate a deleted file.
(Andrew King, #537442)

* ``bzr export`` to zip files will now set a mode on directories.
(Jelmer Vernooij, #207253)

* ``bzr export`` to tgz files will only write out the basename of the
tarfile to the gzip file. (Jelmer Vernooij, #102234)

* ``bzr push --overwrite`` with an older revision specified will now correctly
roll back the target branch. (Jelmer Vernooij, #386576)

* ``bzr lp-propose`` can now propose merges against packaging branches on
Launchpad without requiring the target branch to be specified.
(Jelmer Vernooij, #704647)

* ``bzr lp-propose`` no longer requires a reviewer to be specified. It will
instead leave setting the reviewer up to Launchpad if it was not specified.
(Jelmer Vernooij, #583772)

* ``bzr pull`` will now exit with exit code 1 if there were tag conflicts.
(Jelmer Vernooij, #213185)

* ``bzr mv`` user errors no longer throw UnicodeEncodeError with non-ascii
paths, however they may still print junk if not on a UTF-8 terminal.
(Martin [gz], #707954)

* ``bzr reconfigure --unstacked`` now copies revisions (and their
ancestors) named in tags into the unstacked repository, not just the
ancestry of the branch's tip. (Andrew Bennetts, #401646)

* ``bzr serve`` no longer crashes when a server_started hook is installed and
IPv6 support is available on the system. (Jelmer Vernooij, #293697)

* ``bzr tags`` will no longer choke on branches with ghost revisions in
their mainline and tags on revisions not in the branch ancestry.
(Jelmer Vernooij, #397556)

* ``bzr whoami`` will now display an error if both a new identity and
``--email`` were specified. (Jelmer Vernooij, #680449)

* ``launchpadlib`` doesn't provide the ``uris`` module in some old versions.
(Vincent Ladeuil, #706835)

* Empty entries in the ``NO_PROXY`` variable are no longer treated as matching
every host.
(Martin Pool, #586341)

* Plugins incompatible with the current version of bzr no longer produce a
  warning on every command invocation. Instead, a message is shown by
  ``bzr plugins`` and in crash reports.
  (#704195, Martin Pool)

* The "pretty" version of ``needs_read_lock`` and ``needs_write_lock`` now
preserves the identity of default parameter values.
(Andrew Bennetts, #718569)

* ``bzr dump-btree --raw`` no longer tracebacks on a B-Tree file
containing no rows. (Eric Siegerman, #715508)

* Fix ``bzr lp-mirror`` to work on command line branch URLs and branches
without an explicit public location. (Max Bowsher)

* On Python 2.6 and higher, use multiprocessing.cpu_count() to retrieve the
number of available processors. (Jelmer Vernooij, #693140)

API Changes
***********

* Added ``Branch.heads_to_fetch`` method. Implementions of the Branch API
must now inherit or implement this method. (Andrew Bennetts, #721328)

* Added ``bzrlib.mergetools`` module with helper functions for working with
the list of external merge tools. (Gordon Tyler, #489915)

* All methods and arguments that were deprecated before 2.0
have been removed. (Jelmer Vernooij)

* Branch formats should now be registered on the format registry
(``bzrlib.branch.format_registry``) rather than using the class
methods on ``BranchFormat``. (Jelmer Vernooij, #714729)

* ``BranchFormat.supports_leaving_lock()`` and
``RepositoryFormat.supports_leaving_lock`` flags have been added.
(Jelmer Vernooij)

* ``Branch.fetch`` implementations must now accept an optional
``fetch_spec`` keyword argument. (Andrew Bennetts)

* ``Branch.import_last_revision_info`` is deprecated. Use the
``import_last_revision_info_and_tags`` method instead.
(Andrew Bennetts)

* ``ControlDirFormat.register_format`` has been removed. Instead,
``Prober`` implementations should now implement a ``known_formats``
method. (Jelmer Vernooij)

* ``bzrlib.revionspec.dwim_revspecs`` is deprecated.
  Use ``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_revspec`` and
  ``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_lazy_revspec``
  instead. (Jelmer Vernooij, #721971)

* ``BzrDirFormat`` has a new attribute ``fixed_components`` that
indicates whether the components of the bzrdir can be upgraded
independent of the ``BzrDir``. (Jelmer Vernooij)

* ``BzrProber.register_format`` and ``BzrProber.unregister_format`` are
now deprecated in favour of the ``BzrProber.formats`` format registry.
(Jelmer Vernooij)

* ``ControlDir`` implementations no longer have to provide the
``get_branch_transport``, ``get_workingtree_transport`` and
``get_repository_transport`` methods. (Jelmer Vernooij, #730325)

* ``Converter`` has been moved from ``bzrlib.bzrdir`` to
``bzrlib.controldir``. (Jelmer Vernooij)

* Repository formats can now provide
  ``_get_extra_interrepo_test_combinations`` in the same module
  to provide extra test combinations for ``bzrlib.tests.per_repository``.
  (Jelmer Vernooij)

* Repository formats should now be registered on the format registry
(``bzrlib.repository.format_registry``) rather than using the class
methods on ``RepositoryFormat``. (Jelmer Vernooij)

* Repository formats can now indicate they do not support the full
  VersionedFiles API by setting the ``supports_full_versioned_files``
  attribute to False. A subset of the VersionedFiles API
  (signatures and text graphs) still needs to be supported.
  (Jelmer Vernooij)

* Repository formats have a new method ``is_deprecated`` that
implementations can override to return True to trigger a deprecation
warning. (Jelmer Vernooij)

* The ``revision_id`` parameter of
  ``Repository.search_missing_revision_ids`` and
  ``InterRepository.search_missing_revision_ids`` is deprecated. It is
  replaced by the ``revision_ids`` parameter. (Andrew Bennetts)

* Working tree formats should now be registered on the format registry
(``bzrlib.working_tree.format_registry``) rather than using the class
methods on ``WorkingTreeFormat``. (Jelmer Vernooij, #714730)

Internals
*********

* ``CatchingExceptionThread`` (formerly ThreadWithException) has been moved
  out of the ``bzrlib.tests`` hierarchy to make it clearer that it can be used
  outside of tests. This class makes it easier to track exceptions in threads
  by cacthing them so they can be re-raised in the controlling thread. It's
  available in the ``bzrlib.cethread`` module. (Vincent Ladeuil)

* ``HookPoint.lazy_hook`` and ``Hooks.install_named_lazy_hook`` can install
hooks for which the callable is loaded lazily. (Jelmer Vernooij)

Testing
*******

* The Range parsing for HTTP requests will correctly parse incomplete ranges.
(Vincent Ladeuil, #731240)
