From the release announcement:
This <https://launchpad.net/bzr/+milestone/2.7.0> is a bugfix release
(20 bugs fixed) over the 2.6 series focusing on test issues triggered
by various python 2.7 updates.
All known fixed bugs are included here.
Users are encouraged to upgrade from the other stable series. bzr 2.7
will be the last series with active python 2.6 testing and support.
Python 2.6 hasn't received any updates since v2.6.9 of 29 Oct 2013.
Python 2.7.9 of 10 Dec 2014 was the oldest version to receive a
security fix with ssl library's match_hostname.
Issues found with existing distfiles:
distfiles/eclipse-sourceBuild-srcIncluded-3.0.1.zip
distfiles/fortran-utils-1.1.tar.gz
distfiles/ivykis-0.39.tar.gz
distfiles/enum-1.11.tar.gz
distfiles/pvs-3.2-libraries.tgz
distfiles/pvs-3.2-linux.tgz
distfiles/pvs-3.2-solaris.tgz
distfiles/pvs-3.2-system.tgz
No changes made to these distinfo files.
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.

#########
:Codename: Surprise
:2.6.0: 2013-07-27
This release marks the start of a new long-term-stable series. From here, we
will only make bugfix releases on the 2.6 series (2.6.1, etc), while 2.7
will become our new development series.
This is a bugfix and polish release over the 2.4 series, with a large number
of bugs fixed (~170 for the 2.5 series alone). The 2.5 series provides a
faster smart protocol implementation for many operations, basic support for
colocated branches. We have started translating bzr with the 2.5 series:
https://translations.launchpad.net/bzr, more than 20 languages have already
been registered but these are the early days, contributions welcome.
Only a few bugfixes have been included since 2.5b6 so all known fixed bugs
are included here.
Users are encouraged to upgrade from the other stable series.
External Compatibility Breaks
*****************************
* ``bzr lp-propose --approve`` now also adds an "Approve" vote to the merge
proposal. (Jonathan Lange)
New Features
************
* ``bzr switch --store`` now stores uncommitted changes in the branch, and
restores them when switching back to the branch. (Aaron Bentley)
* New option '--context' for 'bzr diff' command, to configure the amount of
context (i.e. showing lines that have not changed). Also available as the
named parameter 'context_lines' to bzrlib.diff.internal_diff(). (Paul Nixon)
* The 'grep' plugin is now shipped with bzr. (Jelmer Vernooij)
* The 'ping' plugin is now shipped with bzr. (Jelmer Vernooij)
Improvements
************
* ``bzr help env-variables`` now points users at ``bzr help configuration``
which has much more detailed information on the same stuff.
(Robert Collins)
* ``bzr lp-find-proposal`` now only cares about the revision-id that is
specified, not the branch you use. This was enabled by a new API call in
Launchpad's web service. (Aaron Bentley)
* Implement authentication.conf password obfuscation, the password_encoding
option can now be set to base64. (Florian Dorn)
* Local configurations files (i.e. accessed on the local file system like
``bazaar.conf`` and ``locations.conf``) are now shared, reducing the
number of IOs when querying a configuation option. (Vincent Ladeuil,
#832042)
* ``bzr lp-propose --approve`` now correctly specifies the approved revision
and provides an "Approve" vote from the proposer, allowing for smoother
interaction with downstream merge tools. (Jonathan Lange)
Bug Fixes
*********
* Add a ``progress_bar`` configuration option defaulting to
``BZR_PROGRESS_BAR``. This can be set in ``bazaar.conf`` or specified from
the command line with ``-Oprogress_bar=text``. (Vincent Ladeuil, #388275)
* ``Authentication.Config`` now always returns unicode user names and passwords.
(Vincent Ladeuil, #514301)
* Fixed a bug where the entire contents of ``/etc/mailname`` is read in.
We only want to read in the first line so that comments could be added
and would be ignored.
(Haw Loeung, #932515)
* Fixed a syntax error in ``doc/ja/user-guide/http_smart_server.txt`` that
causes breakage with docutils 0.9.1.
(Vincent Ladeuil, Jelmer Vernooij, #1066307)
* Support utf8 characters in platform names even without looking inside the
box (Fedora's Schrödinger's Cat).
(Toshio Kuratomi, Vincent Ladeuil, #1195783)
* Warn when ``--show-base`` is used for ``pull`` in a treeless branch
instead of failing. It's useless but harmless. (Vincent Ladeuil, #1022160)
* When a missing referenced chk root error is encountered, bzr now suggests
running ``bzr reconcile --canonicalize-chks``. (Jelmer Vernooij)
* When pushing a specific revision, create the new working tree at
that revision. (#484516, Neil Martinsen-Burrell)
Documentation
*************
* Clarify ``bzr config`` usages especially around other option references
expansion. (Vincent Ladeuil, #996401)
API Changes
***********
* None.
Internals
*********
* Add __iter__ to http ResponseFile. (Jelmer Vernooij, #1184021)
* The launchpad plugin now requires API 1.6.0 or later. This version shipped
with Ubuntu 9.10. (Aaron Bentley)
* Better align with upstream gzip.py in tuned_gzip.py. We may lose a bit of
performance but that's for knit and weave formats and already partly
deprecated, better keep compatibility than failing fast ;)
(Vincent Ladeuil, #1116079)
Testing
*******
* Fix test failures occurring only with LC_ALL=C, when prompting a user,
``stderr`` encoding should be preferred over terminal encoding if
available. (Vincent Ladeuil, #1086209)
bzr 2.6b2
#########

New Features
************
* New option ``--overwrite-tags`` for ``bzr pull`` and ``bzr push``.
(Jelmer Vernooij, #681792)

the more complex 'file://.,branch=NAME'. (Jelmer Vernooij, #833665)
Bug Fixes
*********
* "bzr missing" now shows tag names when displaying revision information.
(#559072, Neil Martinsen-Burrell)
* Fix ``branch.conf`` saving when unlocking the branch for BranchFormat4.
(Vincent Ladeuil, #1020007)
* Implement ``ResponseFile.readline`` and ``ReponseFile.tell``,
fixing some clones over HTTP. (Jelmer Vernooij, #963769)
* Option values set on locked branches should be saved only when the branch
is finally unlocked. (Vincent Ladeuil, #948339)
Documentation
*************
* Document "bzr lp-propose", "bzr register-branch" and
the other Launchpad plugin commands in bzr(1).
(Jelmer Vernooij, #843801, #163995)

registry is empty. (Vincent Ladeuil, #956860)
* Generate ``ENVIRONMENT`` section in bzr(1) from known environment variable
list rather than hardcoding. (Jelmer Vernooij, #197618)
API Changes
***********
* ``register_filter_stack_map`` and ``lazy_register_filter_stack_map``
are noew deprecated. Instead, use ``filter_stacks_registry.register``
and ``filter_stacks_registry.register_lazy``.
(Jelmer Vernooij)
* Remove deprecated Branch.import_last_revision(). (Jelmer Vernooij)
* Remove deprecated ``RepositoryFormat.register_format``.
(Jelmer Vernooij)
* Remove deprecated Repository.get_ancestry(). (Jelmer Vernooij)

has been removed. (Jelmer Vernooij)
Internals
*********
None.
Testing
*******
* Fix test failures by removing a remaining reference to ``features.sphinx``
which isn't needed anymore since we don't test the texinfo sphinx builder
anymore either. (Vincent Ladeuil)
bzr 2.6b1
#########
:2.6b1: 2012-03-15
This is the first beta for the 2.6 series, leading up to a 2.6.0 release in
August 2012.
This release includes ssl certificates verification from the urllib-based
http implementation turned on by default, fixes some UI issues around
colocated branches, documentation fixes and more.
This release includes all bugs fixed in previous series known at the time of
this release.
Beta releases are suitable for everyday use but may cause some
incompatibilities with plugins. Some plugins may need small updates to work
with 2.6b1.
External Compatibility Breaks
*****************************
None.
Improvements
************
* Access to HTTPS URLs now uses the urrllib implementation by default.
For the old pycurl-based implementation, specify ``https+pycurl://`` as
the URL scheme when accessing a HTTPS location.
(Jelmer Vernooij, #125055)
* Add short option alias ``-N`` for ``--no-recurse``.
(Jelmer Vernooij, #945904)
* Avoid 'Invalid range access' errors when whole files are retrieved with
transport.http.get() . (Vincent Ladeuil, #924746)
* ``bzr rmbranch`` now supports removing colocated branches.
(Jelmer Vernooij, #920653)
* ``bzr rmbranch`` no longer removes active branches unless ``--force``
is specified. (Jelmer Vernooij, #922953)
* ``bzr verify-signatures`` now shows a progress bar.
(Jelmer Vernooij)
* Two new command hooks, ``pre_command`` and ``post_command``,
provide notification before and after a command has been run.
(Brian de Alwis, Jelmer Vernooij)
Bug Fixes
*********
* Fix ``bzr config`` display for ``RegistryOption`` values.
(Vincent Ladeuil, #930182)
Documentation
*************
* Prevent lines of command descriptions starting with a dot to
accidentally be interpreted as a roff macro in bzr(1).
(Jelmer Vernooij, #711079)

an old style Config object. (Jelmer Vernooij)
* New method ``Repository.verify_revision_signatures``.
(Jelmer Vernooij)
* New configuration option class ``RegistryOption`` which is backed
onto a registry. (Jelmer Vernooij)

in addition to a path. (Jelmer Vernooij)
* Turn config option expansion on by default. The only options for which
this should be disabled are templates which should already have used

Whitespace cleanups and other nits corrected, where necessary.
This is a bugfix release. Most of the bugs dealt https and colocated
branches glitches. Upgrading is recommended for all users of earlier 2.5
releases.
Work has gone in to reducing memory usage in the 2.1 series.
This is a small bugfix release. Upgrading is recommended for anyone
running 2.1.0 or earlier.
Bugfixes:
* Avoid malloc(0) in patiencediff, which is non-portable.
* Fix stub sftp test server to call os.getcwdu().
* Merge correctly when this_tree is not a WorkingTree.
* Warn if pyrex is too old to compile the new SimpleSet and StaticTuple
extensions, rather than having the build fail randomly.
bzr 2.0.3
#########
:Codename: little italy
:2.0.3: 2009-12-14
The third stable release of Bazaar has a small handful of bugfixes. As
expected, this has no internal or external compatibility changes versus
2.0.2 (or 2.0.0).
Bug Fixes
*********
* ``bzr push --use-existing-dir`` no longer crashes if the directory
exists but contains an invalid ``.bzr`` directory.
(Andrew Bennetts, #423563)
* Content filters are now applied correctly after pull, merge and switch.
(Ian Clatworthy, #385879)
* Fix a potential segfault in the groupcompress hash map handling code.
When inserting new entries, if the final hash bucket was empty, we could
end up trying to access if ``(last_entry+1)->ptr == NULL``.
(John Arbash Meinel, #490228)
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
bzr 2.0.2
#########
:Codename: after the scare
:2.0.2: 2009-11-02
The second in our "let's keep the stable bugfixes flowing" series. As
expected this has a few (~9) bugfixes relative to 2.0.1, and no major api
changes or features.
Bug Fixes
*********
* Avoid "NoneType has no attribute st_mode" error when files disappear
from a directory while it's being read. (Martin Pool, #446033)
* Content filters are now applied correctly after revert.
(Ian Clatworthy)
* Diff parsing handles "Binary files differ" hunks. (Aaron Bentley, #436325)
* Fetching from stacked pre-2a repository via a smart server no longer
fails intermittently with "second push failed to complete".
(Andrew Bennetts, #437626)
* Fix typos left after test_selftest refactoring.
(Vincent Ladeuil, Matt Nordhoff, #461149)
* Fixed ``ObjectNotLocked`` errors during ``bzr log -r NNN somefile``.
(Andrew Bennetts, #445171)
* PreviewTree file names are not limited by the encoding of the temp
directory's filesystem. (Aaron Bentley, #436794)
Improvements
************
* ``bzr log`` now read-locks branches exactly once, so makes better use of
data caches. (Andrew Bennetts)
Documentation
*************
* Filtered views user documentation upgraded to refer to format 2a
instead of pre-2.0 formats. (Ian Clatworthy)
#########
:Codename: Stability First
:2.0.1: 2009-10-14
The first of our new ongoing bugfix-only stable releases has arrived. It
includes a collection of 12 bugfixes applied to bzr 2.0.0, but does not
include any of the feature development in the 2.1.0 series.
Bug Fixes
*********
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
filename will issue a warning and skip over those files.
(Robert Collins, #3918)
* bzr will attempt to authenticate with SSH servers that support
``keyboard-interactive`` auth but not ``password`` auth when using
Paramiko. (Andrew Bennetts, #433846)
* Fixed fetches from a stacked branch on a smart server that were failing
with some combinations of remote and local formats. This was causing
"unknown object type identifier 60" errors. (Andrew Bennetts, #427736)
* Fixed ``ObjectNotLocked`` errors when doing some log and diff operations
on branches via a smart server. (Andrew Bennetts, #389413)
* Handle things like ``bzr add foo`` and ``bzr rm foo`` when the tree is
at the root of a drive. ``osutils._cicp_canonical_relpath`` always
assumed that ``abspath()`` returned a path that did not have a trailing
``/``, but that is not true when working at the root of the filesystem.
(John Arbash Meinel, Jason Spashett, #322807)
* Hide deprecation warnings for 'final' releases for python2.6.
(John Arbash Meinel, #440062)
* Improve the time for ``bzr log DIR`` for 2a format repositories.
We had been using the same code path as for <2a formats, which required
iterating over all objects in all revisions.
(John Arbash Meinel, #374730)
* Make sure that we unlock the tree if we fail to create a TreeTransform
object when doing a merge, and there is limbo, or pending-deletions
directory. (Gary van der Merwe, #427773)
* Occasional IndexError on renamed files have been fixed. Operations that
set a full inventory in the working tree will now go via the
apply_inventory_delta code path which is simpler and easier to
understand than dirstates set_state_from_inventory method. This may
have a small performance impact on operations built on _write_inventory,
but such operations are already doing full tree scans, so no radical
performance change should be observed. (Robert Collins, #403322)
* Retrieving file text or mtime from a _PreviewTree has good performance when
there are many changes. (Aaron Bentley)
* The CHK index pages now use an unlimited cache size. With a limited
cache and a large project, the random access of chk pages could cause us
to download the entire cix file many times.
(John Arbash Meinel, #402623)
* When a file kind becomes unversionable after being added, a sensible
error will be shown instead of a traceback. (Robert Collins, #438569)
Documentation
*************
* Improved README. (Ian Clatworthy)
* Improved upgrade documentation for Launchpad branches.
(Barry Warsaw)
#########
:2.0.0: 2009-09-22
:Codename: Instant Karma
This release of Bazaar makes the 2a (previously 'brisbane-core') format
the default when new branches or repositories are created. This format is
substantially smaller and faster for many operations. Most of the work in
this release focuses on bug fixes and stabilization, covering both 2a and
previous formats. (See the Upgrade Guide for information on migrating
existing projects.)
This release also improves the documentation content and presentation,
including adding Windows HtmlHelp manuals.
The Bazaar team decided that 2.0 will be a long-term supported release,
with bugfix-only 2.0.x releases based on it, continuing for at least six
months or until the following stable release.
Changes from 2.0.0rc2 to final
******************************
* Officially branded as 2.0.0 rather than 2.0 to clarify between things
that "want to happen on the 2.0.x stable series" versus things that want
to "land in 2.0.0". (Changes how bzrlib._format_version_tuple() handles
micro = 0.) (John Arbash Meinel)
bzr 2.0.0rc2
############
:2.0.0rc2: 2009-09-10
New Features
************
* Added post_commit hook for mutable trees. This allows the keywords
plugin to expand keywords on files changed by the commit.
(Ian Clatworthy, #408841)
Bug Fixes
*********
* Bazaar's native protocol code now correctly handles EINTR, which most
noticeably occurs if you break in to the debugger while connected to a
bzr+ssh server. You can now can continue from the debugger (by typing
'c') and the process continues. However, note that pressing C-\ in the
shell may still kill the SSH process, which is bug 162509, so you must
sent a signal to the bzr process specifically, for example by typing
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
* ``bzr check`` in pack-0.92, 1.6 and 1.9 format repositories will no
longer report incorrect errors about ``Missing inventory ('TREE_ROOT', ...)``
(Robert Collins, #416732)
* ``bzr info -v`` on a 2a format still claimed that it was a "Development
format" (John Arbash Meinel, #424392)
* ``bzr log stacked-branch`` shows the full log including
revisions that are in the fallback repository. (Regressed in 2.0rc1).
(John Arbash Meinel, #419241)
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
traceback. (Martin Pool, #109115)
* Conversion to 2a will create a single pack for all the new revisions (as
long as it ran without interruption). This improves both ``bzr upgrade``
and ``bzr pull`` or ``bzr merge`` from local branches in older formats.
The autopack logic that occurs every 100 revisions during local
conversions was not returning that pack's identifier, which resulted in
the partial packs created during the conversion not being consolidated
at the end of the conversion process. (Robert Collins, #423818)
* Fetches from 2a to 2a are now again requested in 'groupcompress' order.
Groups that are seen as 'underutilized' will be repacked on-the-fly.
This means that when the source is fully packed, there is minimal
overhead during the fetch, but if the source is poorly packed the result
is a fairly well packed repository (not as good as 'bzr pack' but
good-enough.) (Robert Collins, John Arbash Meinel, #402652)
* Fix a potential segmentation fault when doing 'log' of a branch that had
ghosts in its mainline. (Evaluating None as a tuple is bad.)
(John Arbash Meinel, #419241)
* Fix a segmentation fault when computing the ``merge_sort`` of a graph
that has a ghost in the mainline ancestry.
(John Arbash Meinel, #419241)
* ``groupcompress`` sort order is now more stable, rather than relying on
``topo_sort`` ordering. The implementation is now
``KnownGraph.gc_sort``. (John Arbash Meinel)
* Local data conversion will generate correct deltas. This is a critical
bugfix vs 2.0rc1, and all 2.0rc1 users should upgrade to 2.0rc2 before
converting repositories. (Robert Collins, #422849)
* Network streams now decode adjacent records of the same type into a
single stream, reducing layering churn. (Robert Collins)
* Prevent some kinds of incomplete data from being committed to a 2a
repository, such as revisions without inventories, a missing chk_bytes
record for an inventory, or a missing text referenced by an inventory.
(Andrew Bennetts, #423506, #406687)
Documentation
*************
* Fix assertion error about "_remember_remote_is_before" when pushing to
older smart servers.
(Andrew Bennetts, #418931)
* Help on hooks no longer says 'Not deprecated' for hooks that are
currently supported. (Ian Clatworthy, #422415)
* PDF and CHM (Windows HtmlHelp) formats are now supported for the
user documentation. The HTML documentation is better broken up into
topics. (Ian Clatworthy)
* The developer and foreign language documents are now separated
out so that searching in the HTML and CHM files produces more
useful results. (Ian Clatworthy)
* The main table of contents now provides links to the new Migration Docs
and Plugins Guide. (Ian Clatworthy)
bzr 2.0.0rc1
############
:Codename: no worries
:2.0.0rc1: 2009-08-26
Compatibility Breaks
********************
* The default format for bzr is now ``2a``. This format brings many
significant performance and size improvements. bzr can pull from
any existing repository into a ``2a`` one, but can only transfer
from ``2a`` into ``rich-root`` repositories. The Upgrade guide
has more information about this change. (Robert Collins)
* On Windows auto-detection of Putty's plink.exe is disabled.
Default SSH client for Windows is paramiko. User still can force
usage of plink if explicitly set environment variable BZR_SSH=plink.
(#414743, Alexander Belchenko)
New Features
************
* ``bzr branch --switch`` can now switch the checkout in the current directory
to the newly created branch. (Lukáš Lalinský)
Bug Fixes
*********
* Fetches were being requested in 'groupcompress' order, but weren't
recombining the groups. Thus they would 'fragment' to get the correct
order, but not 'recombine' to actually benefit from it. Until we get
recombining to work, switching to 'unordered' fetches avoids the
fragmentation. (John Arbash Meinel, #402645)
* Fix a pycurl related test failure on karmic by recognizing an error
raised by newer versions of pycurl.
(Vincent Ladeuil, #306264)
* Fix a test failure on karmic by making a locale test more robust.
(Vincent Ladeuil, #413514)
* Fix IndexError printing CannotBindAddress errors.
(Martin Pool, #286871)
* Fix "Revision ... not present" errors when upgrading stacked branches,
or when doing fetches from a stacked source to a stacked target.
(Andrew Bennetts, #399140)
* ``bzr branch`` of 2a repositories over HTTP is much faster. bzr now
batches together small fetches from 2a repositories, rather than
fetching only a few hundred bytes at a time.
(Andrew Bennetts, #402657)
Improvements
************
* A better description of the platform is shown in crash tracebacks, ``bzr
--version`` and ``bzr selftest``.
(Martin Pool, #409137)
* bzr can now (again) capture crash data through the apport library,
so that a single human-readable file can be attached to bug reports.
This can be disabled by using ``-Dno_apport`` on the command line, or by
putting ``no_apport`` into the ``debug_flags`` section of
``bazaar.conf``.
(Martin Pool, Robert Collins, #389328)
* ``bzr push`` locally on windows will no longer give a locking error with
dirstate based formats. (Robert Collins)
* ``bzr shelve`` and ``bzr unshelve`` now work on windows.
(Robert Collins, #305006)
* Commit of specific files no longer prevents using the the iter_changes
codepath. On 2a repositories, commit of specific files should now be as
fast, or slightly faster, than a full commit. (Robert Collins)
* The internal core code that handles specific file operations like
``bzr st FILENAME`` or ``bzr commit FILENAME`` has been changed to
include the parent directories if they have altered, and when a
directory stops being a directory its children are always included. This
fixes a number of causes for ``InconsistentDelta`` errors, and permits
faster commit of specific paths. (Robert Collins, #347649)
Documentation

##########
:Codename: nein nein nein!
:1.18.1: 2009-09-09
This release fixes two small but worthwhile bugs relevant to users on
Microsoft Windows: some commands that failed on with locking errors will
now work, and a bug that caused poor performance after committing a file
with line-ending conversion has now been fixed. It also fixes a bug in
pushing to older servers.
Bug Fixes
*********
* Fixed a problem where using content filtering and especially end-of-line
conversion will commit too many copies a file.
(Martin Pool, #415508)
* Fix assertion error about ``_remember_remote_is_before`` in
``set_tags_bytes`` when pushing to older smart servers.
(Andrew Bennetts, Alexander Belchenko, #418931)
Improvements
************
* ``bzr push`` locally on Windows will no longer give a locking error with
dirstate based formats. (Robert Collins)
* ``bzr shelve`` and ``bzr unshelve`` now work on Windows.

:Codename: little traveller
:1.18: 2009-08-20
:1.18rc1: 2009-08-10
This release of Bazaar marches on towards the 2.0 release in which the 2a
'brisbane-core' format becomes generally recommended. Most of the work in
this release now focusses on bug fixes and stabilization, covering both 2a
and previous formats. There is a new text-mode interactive merge feature,
a new guide to migration to 2a format in the user documentation, and
pushing branches to a smart server is now much faster.
The Bazaar team decided that 2.0 will be a long-term supported release,
with bugfix-only releases based on it continuing for at least six months
or until the following stable release.
There are no changes from 1.18rc1 to 1.18.
New Features
************
* ``bzr merge --interactive`` applies a user-selected portion of the
merge. The UI is similar to ``shelve``. (Aaron Bentley)
* ``bzr reconfigure`` now takes options ``--stacked-on URL`` and
``--unstacked`` to change stacking of a branch.
(Martin Pool, #391411)
Bug Fixes
*********
* Annotating on a stacked branch will now succeed in simple scenarios.
There are still some complex scenarios where it will fail (bug #399884)
(John Arbash Meinel, #393366)
* A progress bar is no longer left dangling when ``bzr selftest``
completes, and the progress bar updates with zero latency so the
displayed test name is always the one that's actually running.
(Martin Pool, #123688)
* Authenticating against an ssh server now uses ``auth_none`` to determine
if password authentication is even supported. This fixes a bug where
users would be prompted for a launchpad password, even though launchpad
only supports publickey authentication. (John Arbash Meinel, #375867)
* BranchBuilder now accepts timezone to avoid test failures in countries far
from GMT. (Vincent Ladeuil, #397716)
* ``bzr commit`` no longer saves the unversioning of missing files until
the commit has completed on the branch. This means that aborting a
commit that found a missing file will leave the tree unedited.
(Robert Collins, #282402)
* ``bzr mv`` no longer takes out branch locks, which allows it to work
when the branch is readonly. (Robert Collins, #216541)
* ``bzr revert .`` no longer generates an InconsistentDelta error when
there are missing subtrees. (Robert Collins, #367632)
* ``bzr send`` now generates valid bundles with ``--2a`` formats. However,
do to internal changes necessary to support this, older clients will
fail when trying to insert them. For newer clients, the bundle can be
used to apply the changes to any rich-root compatible format.
(John Arbash Meinel, #393349)
* Cope with FTP servers that don't support restart/append by falling back
to reading and then rewriting the whole file, such as TahoeLAFS. (This
fallback may be slow for some access patterns.) (Nils Durner, #294709)
* Encode the paths in ``mbcs`` encoding on Windows when spawning an
external diff client. This at least allows supporting filenames that are
not ascii, but are present in the current locale. Ideally we would be
able to pass the Unicode path, but that would be client dependent.
(John Arbash Meinel, #382709)
* Fix a compile bug on Solaris having to do with const and
pointer-to-pointers. (John Arbash Meinel, #408441)
* Fixed a NameError that occurs when merging or pulling from a URL that
causes a redirection loop when bzr tries to read a URL as a bundle.
(Andrew Bennetts, #400847)
* Fix ``AttributeError: 'TestUIFactory' object has no attribute 'tick'``
running send and similar commands on 2a formats.
(Martin Pool, #408201)
* Fixed export to existing directory: if directory is empty then export
will succeed, otherwise it fails with error.
(Alexander Belchenko, #406174)
* Fixed spurious "Source branch does not support stacking" warning when
pushing. (Andrew Bennetts, #388908)
* Fixed spurious transport activity indicator appearing while tests are
running. (Martin Pool, #343532)
* Merge now correctly handles empty right-hand revision specs.
(Aaron Bentley, #333961)
* Renames to lexographically lower basenames in trees that have never been
committed to will no longer corrupt the dirstate. This was caused by an
bug in the dirstate update_minimal method. (Robert Collins, #395556)
* Requests for unknown methods no longer cause the smart server to log
lots of backtraces about ``UnknownSmartMethod``, ``do_chunk`` or
``do_end``. (Andrew Bennetts, #338561)
* Streaming from bzr servers where there is a chain of stacked branches
(A stacked on B stacked on C) will now work. (Robert Collins, #406597)
* The environment variable ``BZR_PROGRESS_BAR`` set to either ``text`` or ``none``
always forces progress bars either on or off respectively. Otherwise,
they're turned on if ``TERM`` is not ``dumb`` and stderr is a terminal.
bzr always uses the 'text' user interface when run as a command, so
``BZR_USE_TEXT_UI`` is no longer needed.
(Martin Pool, #339385, #387717)
* The optional ``_knit_load_data_pyx`` C extension was never being
imported. This caused significant slowdowns when reading data from
repositories. (Andrew Bennetts, #405653)
* The ``--hardlink`` option to ``branch`` and ``checkout`` is not
supported at the moment on workingtree formats that can do content
filtering. (See <https://bugs.edge.launchpad.net/bzr/+bug/408193>.)
bzr now says so, rather than just ignoring the option. (Martin Pool)
* There was a bug in ``osutils.relpath`` that was only triggered on
Windows. Essentially if you were at the root of a drive, and did
something to a branch/repo on another drive, we would go into an
infinite loop while trying to find a 'relative path'.
(John Arbash Meinel, #394227)
* ``WorkingTree4.unversion`` will no longer fail to unversion ids which
were present in a parent tree but renamed in the working tree.
(Robert Collins, #187207)
Improvements
************
* Can now rename/move files even if they have been removed from the inventory.
(Marius Kruger)
* Pushing branches with tags via ``bzr://`` and ``bzr+ssh://`` is much
faster, using a new ``Branch.set_tags_bytes`` smart server verb rather
than VFS methods. For example, pushes of small branches with tags take
11 rather than 18 smart server requests. (Andrew Bennetts, #398608)
* Sending Ctrl-Break on Windows will now drop you into the debugger, in
the same way that sending Ctrl-\\ does on other platforms.
(John Arbash Meinel)
Documentation
*************
* Added Bazaar 2.0 Upgrade Guide. (Ian Clatworthy)
API Changes
***********
* ``CLIUIFactory`` is deprecated; use ``TextUIFactory`` instead if you
need to subclass or create a specific class, or better yet the existing
``make_ui_for_terminal``. ``SilentUIFactory`` is clarified to do no
user interaction at all, rather than trying to read from stdin but not
writing any output, which would be strange if reading prompts or
passwords. (Martin Pool)
* New TransformPreview.commit() allows committing without a working tree.
(Aaron Bentley)
* ``pb`` parameter to ``TextTestResult`` is deprecated and ignored.
(Martin Pool)
* ProgressTasks now prefer to talk direct to their ProgressView not to the
UIFactory.
(Martin Pool)
* ``WorkingTree._check`` now requires a references dict with keys matching
those returned by ``WorkingTree._get_check_refs``. (Robert Collins)
Internals
*********
* ``CHKInventory.path2id`` uses the parent_id to basename hash to avoid
reading the entries along the path, reducing work to lookup ids from
paths. (Robert Collins)
* ``CHKMap.apply_delta`` now raises ``InconsistentDelta`` if a delta adds
as new a key which was already mapped. (Robert Collins)
* Inventory delta application catches more cases of corruption and can
prevent corrupt deltas from affecting consistency of data structures on
disk. (Robert Collins)
* --subunit support now adds timestamps if the subunit version supports
it. (Robert Collins)
* The Windows all-in-one installer now bundles the PyQt image format
plugins, which allows previewing more images as part of 'qdiff'.
(Alexander Belchenko)
Testing
*******
* Merge directive cherrypick tests must use the same root id.
(Martin Pool, #409684)
* Spurious failure in ``check`` tests on rich-root formats fixed.
(Martin Pool, #408199)
* The ``bzrlib.tests.TextTestRunner`` will no longer call
``countTestsCases`` on the test being run. Progress information is
instead handled by having the test passed in call ``result.progress``
before running its contents. This improves the behaviour when using
``TextTestRunner`` with test suites that don't support
``countTestsCases``. (Robert Collins)
Bazaar continues to blaze a straight and shining path to the 2.0 release and
the elevation of the ``2a`` beta format to the full glory of "supported and
stable".
Highlights in this release include greatly reduced memory consumption during
commits, faster ``ls``, faster ``annotate``, faster network operations if
you're specifying a revision number and the final destruction of those
annoying progress bar artifacts.
#####################
End user testing of the 2a format revealed two serious bugs. The first,
#365615, caused bzr to raise AbsentContentFactory errors when autopacking.
This meant that commits or pushes to 2a-format repositories failed
intermittently.
The second bug, #390563, caused the smart server to raise AbsentContentFactory
when streaming 2a stacked 2a-format branches. This particularly affected
branches stored on Launchpad in the 2a format.
Bug Fixes
*********
* We now properly request a more minimal set of file texts when fetching
multiple revisions. (Robert Collins, John Arbash Meinel, #390563)
* Repositories using CHK pages (which includes the new 2a format) will no
longer error during commit or push operations when an autopack operation
is triggered. (Robert Collins, #365615)
* ``chk_map.iter_interesting_nodes`` now properly uses the *intersection*
of referenced nodes rather than the *union* to determine what
uninteresting pages we still need to look at. Prior to this,
incrementally pushing to stacked branch would push the minimal data, but
fetching everything would request extra texts. There are some unhandled
cases wrt trees of different depths, but this fixes the common cases.
(Robert Collins, John Arbash Meinel, #390563)
* ``GroupCompress`` repositories now take advantage of the pack hints
parameter to permit cross-format fetching to incrementally pack the
converted data. (Robert Collins)
* ``Repository.commit_write_group`` now returns opaque data about what
was committed, for passing to the ``Repository.pack``. Repositories
without atomic commits will still return None. (Robert Collins)
* ``Repository.pack`` now takes an optional ``hint`` parameter
which will support doing partial packs for repositories that can do
that. (Robert Collins)
* RepositoryFormat has a new attribute 'pack_compresses' which is True
when doing a pack operation changes the compression of content in the
repository. (Robert Collins)
* ``StreamSink`` and ``InterDifferingSerialiser`` will call
``Repository.pack`` with the hint returned by
``Repository.commit_write_group`` if the formats were different and the
repository can increase compression by doing a pack operation.

:1.16: 2009-06-18
This version of Bazaar contains the beta release of the new ``2a`` repository
format, suitable for testing by fearless, advanced users. This format or an
updated version of it will become the default format in Bazaar 2.0. Please
read the NEWS entry before even thinking about upgrading to the new format.
Also included are speedups for many operations on huge projects, a bug fix for
pushing stacked new stacked branches to smart servers and the usual bevy of
bug fixes and improvements.
Changes from 1.16rc1 to 1.16final
*********************************
* Fix the nested tree flag check so that upgrade from development formats to
2a can work correctly.
(Jelmer Vernooij, #388727)
* Automatic format upgrades triggered by default stacking policies on a
1.16rc1 (or later) smart server work again.
(Andrew Bennetts, #388675)
Compatibility Breaks
********************
* Display prompt on stderr (instead of stdout) when querying users so
that the output of commands can be safely redirected.
(Vincent Ladeuil, #376582)
New Features
************
* A new repository format ``2a`` has been added. This is a beta release
of the the brisbane-core (aka group-compress) project. This format now
suitable for wider testing by advanced users willing to deal with some
bugs. We would appreciate test reports, either positive or negative.
Format 2a is substantially smaller and faster for many operations on
many trees. This format or an updated version will become the default
in bzr 2.0.
This is a rich-root format, so this repository format can be used with
bzr-svn. Bazaar branches in previous non-rich-root formats can be
converted (including by merge, push and pull) to format 2a, but not vice
versa. We recommend upgrading previous development formats to 2a.
Upgrading to this format can take considerable time because it expands
and more concisely repacks the full history.
If you use stacked branches, you must upgrade the stacked branches
before the stacked-on branches. (See <https://bugs.launchpad.net/bugs/374735>)
* ``--development7-rich-root`` is a new dev format, similar to ``--dev6``
but using a Revision serializer using bencode rather than XML.
(Jelmer Vernooij, John Arbash Meinel)
* mail_client=claws now supports --body (and message body hooks). Also uses
configured from address. (Barry Warsaw)
Improvements
************
* ``--development6-rich-root`` can now stack. (Modulo some smart-server
bugs with stacking and non default formats.)
(John Arbash Meinel, #373455)
* ``--development6-rich-root`` delays generating a delta index for the
first object inserted into a group. This has a beneficial impact on
``bzr commit`` since each committed texts goes to its own group. For
committing a 90MB file, it drops peak memory by about 200MB, and speeds
up commit from 7s => 4s. (John Arbash Meinel)
* Numerous operations are now faster for huge projects, i.e. those
with a large number of files and/or a large number of revisions,
particularly when the latest development format is used. These
operations (and improvements on OpenOffice.org) include:
* branch in a shared repository (2X faster)
* branch --no-tree (100X faster)
* diff (2X faster)
* tags (70X faster)
(Ian Clatworthy)
* Pyrex version of ``bencode`` support. This provides optimized support
for both encoding and decoding, and is now found at ``bzrlib.bencode``.
``bzrlib.utils.bencode`` is now deprecated.
(Alexander Belchenko, Jelmer Vernooij, John Arbash Meinel)
Bug Fixes
*********
* Bazaar can now pass attachment files to the mutt email client.
(Edwin Grubbs, #384158)
* Better message in ``bzr add`` output suggesting using ``bzr ignored`` to
see which files can also be added. (Jason Spashett, #76616)
* ``bzr pull -r 123`` from a stacked branch on a smart server no longer fails.
Also, the ``Branch.revision_history()`` API now works in the same
situation. (Andrew Bennetts, #380314)
* ``bzr serve`` on Windows no longer displays a traceback simply because a
TCP client disconnected. (Andrew Bennetts)
* Clarify the rules for locking and fallback repositories. Fix bugs in how
``RemoteRepository`` was handling fallbacks along with the
``_real_repository``. (Andrew Bennetts, John Arbash Meinel, #375496)
* Fix a small bug with fetching revisions w/ ghosts into a new stacked
branch. Not often triggered, because it required ghosts to be part of
the fetched revisions, not in the stacked-on ancestry.
(John Arbash Meinel)
* Fix status and commit to work with content filtered trees, addressing
numerous bad bugs with line-ending support. (Ian Clatworthy, #362030)
* Fix problem of "directory not empty" when contending for a lock over
sftp. (Martin Pool, #340352)
* Fix rule handling so that eol is optional, not mandatory.
(Ian Clatworthy, #379370)
* Pushing a new stacked branch to a 1.15 smart server was broken due to a
bug in the ``BzrDirFormat.initialize_ex`` smart verb. This is fixed in
1.16, but required changes to the network protocol, so the
``BzrDirFormat.initialize_ex`` verb has been removed and replaced with a
corrected ``BzrDirFormat.initialize_ex_1.16`` verb. 1.15 clients will
still work with a 1.16 server as they will fallback to slower (and
bug-free) methods.
(Jonathan Lange, Robert Collins, Andrew Bennetts, #385132)
* Reconcile can now deal with text revisions that originated in revisions
that are ghosts. (Jelmer Vernooij, #336749)
* Support cloning of branches with ghosts in the left hand side history.
(Jelmer Vernooij, #248540)
* The ''bzr diff'' now catches OSError from osutils.rmtree and logs a
helpful message to the trace file, unless the temp directory really was
removed (which would be very strange). Since the diff operation has
succeeded from the user's perspective, no output is written to stderr
or stdout. (Maritza Mendez, #363837)
* Translate errors received from a smart server in response to a
``BzrDirFormat.initialize`` or ``BzrDirFormat.initialize_ex`` request.
This was causing tracebacks even for mundane errors like
``PermissionDenied``. (Andrew Bennetts, #381329)
Documentation
*************
* Added directory structure and started translation of docs in Russian.
(Alexey Shtokalo, Alexander Iljin, Alexander Belchenko, Dmitry Vasiliev,
Volodymyr Kotulskyi)
API Changes
***********
* Added osutils.parent_directories(). (Ian Clatworthy)
* ``bzrlib.progress.ProgressBar``, ``ChildProgress``, ``DotsProgressBar``,
``TTYProgressBar`` and ``child_progress`` are now deprecated; use
``ui_factory.nested_progress_bar`` instead. (Martin Pool)
* ``graph.StackedParentsProvider`` is now a public API, replacing
``graph._StackedParentsProvider``. The api is now considered stable and ready
for external users. (Gary van der Merwe)
* ``bzrlib.user_encoding`` is deprecated in favor of
``get_user_encoding``. (Alexander Belchenko)
* TreeTransformBase no longer assumes that limbo is provided via disk.
DiskTreeTransform now provides disk functionality. (Aaron Bentley)
Internals
*********
* Remove ``weave.py`` script for accessing internals of old weave-format
repositories. (Martin Pool)
Testing
*******
* The number of cores is now correctly detected on OSX. (John Szakmeister)
* The number of cores is also detected on Solaris and win32. (Vincent Ladeuil)
* The number of cores is also detected on FreeBSD. (Matthew Fuller)
bzr 1.15
########
:1.15rc1: 2009-05-16
:1.15: 2009-05-22
:1.15.1: 2009-06-09
The smart server will no longer raise 'NoSuchRevision' when streaming content
with a size mismatch in a reconstructed graph search. New command ``bzr
dpush``. Plugins can now define their own annotation tie-breaker when two
revisions introduce the exact same line.
Changes from 1.15.1 to 1.15.2
*****************************
* Use zdll on Windows to build ``_chk_map_pyx`` extension.
(Alexander Belchenko)
Changes from 1.15final to 1.15.1
*********************************
* Translate errors received from a smart server in response to a
``BzrDirFormat.initialize`` or ``BzrDirFormat.initialize_ex`` request.
This was causing tracebacks even for mundane errors like
``PermissionDenied``. (Andrew Bennetts, #381329)
Changes from 1.15rc1 to 1.15final
*********************************
* No changes
Compatibility Breaks
********************
* ``bzr ls`` is no longer recursive by default. To recurse, use the
new ``-R`` option. The old ``--non-recursive`` option has been removed.
If you alias ``ls`` to ``ls -R``, you can disable recursion using
``--no-recursive`` instead. (Ian Clatworthy)
New Features
************
* New command ``bzr dpush`` that can push changes to foreign
branches (svn, git) without setting custom bzr-specific metadata.
(Jelmer Vernooij)
* The new development format ``--development6-rich-root`` now supports
stacking. We chose not to use a new format marker, since old clients
will just fail to open stacked branches, the same as if we used a new
format flag. (John Arbash Meinel, #373455)
* Plugins can now define their own annotation tie-breaker when two revisions
introduce the exact same line. See ``bzrlib.annotate._break_annotation_tie``
Be aware though that this is temporary, private (as indicated by the leading
'_') and a first step to address the problem. (Vincent Ladeuil, #348459)
* New command ``bzr dpush`` that can push changes to foreign
branches (svn, git) without setting custom bzr-specific metadata.
(Jelmer Vernooij)
* ``bzr send`` will now check the ``child_submit_format`` setting in
the submit branch to determine what format to use, if none was
specified on the command-line. (Jelmer Vernooij)
Improvements
************
* -Dhpss output now includes the number of VFS calls made to the remote
server. (Jonathan Lange)
* ``--coverage`` works for code running in threads too.
(Andrew Bennets, Vincent Ladeuil)
* ``bzr pull`` now has a ``--local`` option to only make changes to the
local branch, and not the bound master branch.
(Gary van der Merwe, #194716)
* ``bzr rm *`` is now as fast as ``bzr rm * --keep``. (Johan Walles, #180116)
Bug Fixes
*********
* Adding now works properly when path contains a symbolic link.
(Geoff Bache, #183831)
* An error is now raised for unknown eol values. (Brian de Alwis, #358199)
* ``bzr merge --weave`` will now generate a conflict if one side deletes a
line, and the other side modifies the line. (John Arbash Meinel, #328171)
* ``bzr reconfigure --standalone`` no longer raises IncompatibleRepositories.
(Martin von Gagern, #248932)
* ``bzr send`` works to send emails again using MAPI.
(Neil Martinsen-Burrell, #346998)
* Check for missing parent inventories in StreamSink. This prevents
incomplete stacked branches being created by 1.13 bzr:// and
bzr+ssh:// clients (which have bug #354036). Instead, the server now
causes those clients to send the missing records. (Andrew Bennetts)
* Correctly handle http servers proposing multiple authentication schemes.
(Vincent Ladeuil, #366107)
* End-Of-Line content filters are now loaded correctly.
(Ian Clatworthy, Brian de Alwis, #355280)
* Fix a bug in the pure-python ``GroupCompress`` code when handling copies
longer than 64KiB. (John Arbash Meinel, #364900)
* Fix TypeError in running ``bzr break-lock`` on some URLs.
(Alexander Belchenko, Martin Pool, #365891)
* Non-recursive ``bzr ls`` now works properly when a path is specified.
(Jelmer Vernooij, #357863)
* ssh usernames (defined in ~/.ssh/config) are honoured for bzr+ssh connections.
(Vincent Ladeuil, #367726)
* Several bugs related to unicode symlinks have been fixed and the test suite
enhanced to better catch regressions for them. (Vincent Ladeuil)
* The smart server will no longer raise 'NoSuchRevision' when streaming
content with a size mismatch in a reconstructed graph search: it assumes
that the client will make sure it is happy with what it got, and this
sort of mismatch is normal for stacked environments.
bzr 1.13.0/1 will stream from unstacked branches only - in that case not
getting all the content expected would be a bug. However the graph
search is how we figured out what we wanted, so a mismatch is both odd
and unrecoverable without starting over, and starting over will end up
with the same data as if we just permitted the mismatch. If data is
gc'd, doing a new search will find only the truncated data, so sending
only the truncated data seems reasonable. bzr versions newer than this
will stream from stacked branches and check the stream to find missing
content in the stacked-on branch, and thus will handle the situation
implicitly. (Robert Collins, #360791)
* Upgrading to, or fetching into a 'rich-root' format will now correctly
set the root data the same way that reconcile does.
(Robert Collins, #368921)
* Using unicode Windows API to obtain command-line arguments.
(Alexander Belchenko, #375934)
Documentation
*************
API Changes
***********
* ``InterPackRepo.fetch`` and ``RepoFetcher`` now raise ``NoSuchRevision``
instead of ``InstallFailed`` when they detect a missing revision.
``InstallFailed`` itself has been deleted. (Jonathan Lange)
* Not passing arguments to ``bzrlib.commands.main()`` will now grab the
arguments from ``osutils.get_unicode_argv()`` which has proper support
for unicode arguments on windows. Further, the supplied arguments are now
required to be unicode strings, rather than user_encoded strings.
(Alexander Belchenko)
Internals
*********
* ``bzrlib.branch.Branch.set_parent`` is now present on the base branch
class and will call ``_set_parent_location`` after doing unicode
encoding. (Robert Collins)
* ``bzrlib.remote.RemoteBranch._set_parent_location`` will use a new verb
``Branch.set_parent_location`` removing further VFS operations.
(Robert Collins)
* ``bzrlib.bzrdir.BzrDir._get_config`` now returns a ``TransportConfig``
or similar when the dir supports configuration settings. The base class
defaults to None. There is a matching new server verb
``BzrDir.get-config_file`` to reduce roundtrips for getting BzrDir
configuration. (Robert Collins)
* ``bzrlib.tests.ExtendedTestResult`` has new methods ``startTests``
called before the first test is started, ``done`` called after the last
test completes, and a new parameter ``strict``. (Robert Collins)
* ``-Dhpss`` when passed to bzr will cause a backtrace to be printed when
VFS operations are started on a smart server repository. This should not
occur on regular push and pull operations, and is a key indicator for
performance regressions. (Robert Collins)
* ``-Dlock`` when passed to the selftest (e.g. ``bzr -Dlock selftest``) will
cause mismatched physical locks to cause test errors rather than just
reporting to the screen. (Robert Collins)
* Fallback ``CredentialStore`` instances registered with ``fallback=True``
are now be able to provide credentials if obtaining credentials
via ~/.bazaar/authentication.conf fails. (Jelmer Vernooij,
Vincent Ladeuil, #321918)
* New hook ``Lock.lock_broken`` which runs when a lock is
broken. This is mainly for testing that lock/unlock are
balanced in tests. (Vincent Ladeuil)
* New MergeDirective hook 'merge_request_body' allows hooks to supply or
alter a body for the message produced by ``bzr send``.
* New smart server verb ``BzrDir.initialize_ex`` which implements a
refactoring to the core of clone allowing less round trips on new
branches. (Robert Collins)
* New method ``Tags.rename_revisions`` that can rename revision ids tags
are pointing at. (Jelmer Vernooij)
* Updated the bundled ``ConfigObj`` library to 4.6.0 (Matt Nordhoff)
Testing
*******
* ``bzr selftest`` will now fail if lock/unlock are not correctly balanced in
tests. Using ``-Dlock`` will turn the related failures into warnings.
(Vincent Ladeuil, Robert Collins)
Compatibility Breaks
********************
* ``bzr ls`` is no longer recursive by default. To recurse, use the
new ``-R`` option. The old ``--non-recursive`` option has been removed.
If you alias ``ls`` to ``ls -R``, you can disable recursion using
``--no-recursive`` instead. (Ian Clatworthy)
New Features
************
* Plugins can now define their own annotation tie-breaker when two revisions
introduce the exact same line. See ``bzrlib.annotate._break_annotation_tie``
Be aware though that this is temporary, private (as indicated by the leading
'_') and a first step to address the problem. (Vincent Ladeuil, #348459)
Improvements
************
Bug Fixes
*********
* Non-recursive ``bzr ls`` now works properly when a path is specified.

bzr 1.14
###########
:Codename: brisbane-core
:1.14rc1: 2009-04-06
:1.14rc2: 2009-04-19
:1.14: 2009-04-28
New formats 1.14 and 1.14-rich-root supporting End-Of-Line (EOL) conversions,
keyword templating (via the bzr-keywords plugin) and generic content filtering.
End-of-line conversion is now supported for formats supporting content
filtering.
Changes from 1.14final to 1.14.1
********************************
* Change api_minimum_version back to api_minimum_version = (1, 13, 0)
Changes from 1.14rc2 to 1.14final
*********************************
* Fix a bug in the pure-python ``GroupCompress`` code when handling copies
longer than 64KiB. (John Arbash Meinel, #364900)
Changes from 1.14rc1 to 1.14rc2
*******************************
* Fix for bug 358037 Revision not in
bzrlib.groupcompress.GroupCompressVersionedFiles (Brian de Alwis,
John A Meinel)
* Fix for bug 354036 ErrorFromSmartServer - AbsentContentFactory object has no
attribute 'get_bytes_as' exception while pulling from Launchpad
(Jean-Francois Roy, Andrew Bennetts, Robert Collins)
* Fix for bug 355280 eol content filters are never loaded and thus never
applied (Brian de Alwis, Ian Clatworthy)
* bzr.dev -r4280 Change _fetch_uses_deltas = False for CHK repos until we can
write a better fix. (John Arbash Meinel, Robert Collins)
* Fix for bug 361574 uncommit recommends undefined --levels and -n options
(Marius Kruger, Ian Clatworthy)
* bzr.dev r4289 as cherrypicked at lp:~spiv/bzr/stacking-cherrypick-1.14
(Andrew Bennetts, Robert Collins)
Compatibility Breaks
********************
* A previously disabled code path to accelerate getting configuration
settings from a smart server has been reinstated. We think this *may*
cause a incompatibility with servers older than bzr 0.15. We intend
to issue a point release to address this if it turns out to be a
problem. (Robert Collins, Andrew Bennetts)
* bzr no longer autodetects nested trees as 'tree-references'. They
must now be explicitly added tree references. At the commandline, use
join --reference instead of add. (Aaron Bentley)
* The ``--long`` log format (the default) no longer shows merged
revisions implicitly, making it consistent with the ``short`` and
``line`` log formats. To see merged revisions for just a given
revision, use ``bzr log -n0 -rX``. To see every merged revision,
use ``bzr log -n0``. (Ian Clatworthy)
New Features
************
* New formats ``1.14`` and ``1.14-rich-root`` supporting End-Of-Line
(EOL) conversions, keyword templating (via the bzr-keywords plugin)
and generic content filtering. These formats replace the experimental
``development-wt5`` and ``development-wt5-rich-root`` formats
respectively, but have support for filtered views disabled.
(Ian Clatworthy)
* New ``mv --auto`` option recognizes renames after they occur.
(Aaron Bentley)
* ``bzr`` can now get passwords from stdin without requiring a controlling
terminal (i.e. by redirecting stdin). (Vincent Ladeuil)
* ``bzr log`` now supports filtering of multiple files and directories
and will show changes that touch any of them. Furthermore,
directory filtering now shows the changes to any children of that
directory, not just the directory object itself.
(Ian Clatworthy, #97715)
* ``bzr shelve`` can now apply changes without storing anything on the
shelf, via the new --destroy option. (Aaron Bentley)
* ``bzr send`` now accepts --body to specify an initial message body.
(Aaron bentley)
* ``bzr xxx --usage`` where xxx is a command now shows a usage
message and the options without the descriptive help sections
(like Description and Examples). A message is also given
explaining how to see the complete help, i.e. ``bzr help xxx``.
(Ian Clatworthy)
* Content filters can now be used to provide custom conversion
between the canonical format of content (i.e. as stored) and
the convenience format of content (i.e. as created in working
trees). See ``bzr help content-filters`` for further details.
(Ian Clatworthy, Alexander Belchenko)
* End-of-line conversion is now supported for formats supporting
content filtering. See ``bzr help eol`` for details.
(Ian Clatworthy)
* Newly-blessed `join` command allows combining two trees into one.
(Aaron Bentley)
Improvements
************
* A new format name alias ``default-rich-root`` has been added and
points at the closest relative of the default format that supports
rich roots. (Jelmer Vernooij, #338061)
* Branching from a stacked branch using ``bzr*://`` will now stream
the data when the target repository does not need topological
ordering, reducing round trips and network overhead. This uses the
existing smart server methods added in 1.13, so will work on any
1.13 or newer server. (Robert Collins, Andrew Bennetts)
* ``bzr cat`` and ``bzr export`` now supports a ``--filters`` option
that displays/saves the content after content filters are applied.
(Ian Clatworthy)
* ``bzr ignore`` gives a more informative message when existing
version controlled files match the ignore pattern. (Neil
Martinsen-Burrell, #248895)
* ``bzr log`` now has ``--include-merges`` as an alias for ``--levels 0``.
(Ian Clatworthy)
* ``bzr send`` is faster on repositories with deep histories.
(Ian Clatworthy)
* Progress bars now show the rate of network activity for
``bzr+ssh://`` and ``bzr://`` connections. (Andrew Bennetts)
* Pushing to a stacked pack-format branch on a 1.12 or older smart server
now takes many less round trips. (Andrew Bennetts, Robert Collins,
#294479)
* Streaming push can be done to older repository formats. This is
implemented using a new ``Repository.insert_stream_locked`` RPC.
(Andrew Bennetts, Robert Collins)
* The "ignoring files outside view: .." message has been re-worded
to "Ignoring files outside view. View is .." to reduce confusion
about what was being considered and what was being ignored.
(Ian Clatworthy)
* The ``long`` log formatter now shows [merge] indicators. If
only one level of revisions is displayed and merges are found,
the ``long`` and ``short`` log formatters now tell the user
how to see the hidden merged revisions. (Ian Clatworthy)
* The ``brisbane-core`` project has delivered its beta format
``development6-rich-root``. This format is suitable for judicious
testing by early adopters. In particular if you are benchmarking bzr
performance please be sure to test using this format. At this stage
more information is best obtained by contacting the Bazaar mailing list
or IRC channel if you are interested in using this format. We will make
end user documentation available closer to blessing the format as
production ready. (Robert Collins, John Arbash Meinel, Ian Clatworthy,
Vincent Ladeuil, Andrew Bennetts, Martin Pool)
* Tildes are no longer escaped. No more %7Euser/project/branch!
(Jonathan Lange)
Bug Fixes
*********
* Pushing a new stacked branch will also push the parent inventories for
revisions at the stacking boundary. This makes sure that the stacked
branch has enough data to calculate inventory deltas for all of its
revisions (without requiring the fallback branch). This avoids
"'AbsentContentFactory' object has no attribute 'get_bytes_as'" errors
when fetching the stacked branch from a 1.13 (or later) smart server.
This partially fixes#354036. (Andrew Bennetts, Robert Collins)
* End-Of-Line content filters are now loaded correctly.
(Ian Clatworthy, Brian de Alwis, #355280)
* Authentication plugins now receive all the parameters from the request
itself (aka host, port, realm, path, etc). Previously, only the
authentication section name, username and encoded password were
provided. (Jean-Francois Roy)
* bzr gives a better message if an invalid regexp is passed to ``bzr log
-m``. (Anne Mohsen, Martin Pool)
* ``bzr split`` now says "See also: join" (Aaron Bentley, #335015)
* ``bzr version-info`` now works in empty branches. (Jelmer Vernooij,
#313028)
* Fix "is not a stackable format" error when pushing a
stackable-format branch with an unstackable-format repository to a
destination with a default stacking policy. (Andrew Bennetts)
* Fixed incorrect "Source format does not support stacking" warning
when pushing to a smart server. (Andrew Bennetts, #334114)
* Fix 'make check-dist-tarball' failure by converting paths to unicode when
needed. (Vincent Ladeuil, #355454)
* Fixed "Specified file 'x/y/z' is outside current view: " occurring
on ``bzr add x/y/z`` in formats supporting views when no view is
defined. (Ian Clatworthy, #344708)
* It is no longer possible to fetch between repositories while the
target repository is in a write group. This prevents race conditions
that prevent the use of RPC's to perform fetch, and thus allows
optimising more operations. (Robert Collins, Andrew Bennetts)
* ``merge --force`` works again. (Robert Collins, #342105)
* No more warnings are issued about ``sha`` being deprecated under python-2.6.
(Vincent Ladeuil, #346593)
* Pushing a new branch to a server that has a stacking policy will now
upgrade from the local branch format when the stacking policy points at
a branch which is itself stackable, because we know the client can read
both branches, we know that the trunk for the project can be read too,
so the upgrade will not inconvenience users. (Robert Collins, #345169)
* Pushing a new stacked branch will also push the parent inventories for
revisions at the stacking boundary. This makes sure that the stacked
branch has enough data to calculate inventory deltas for all of its
revisions (without requiring the fallback branch). This avoids
"'AbsentContentFactory' object has no attribute 'get_bytes_as'" errors
when fetching the stacked branch from a 1.13 (or later) smart server.
This partially fixes#354036. (Andrew Bennetts, Robert Collins)
* The full test suite is passing again on OSX. Several minor issues (mostly
test related) have been fixed. (Vincent Ladeuil, #355273).
* The GNU Changelog formatter is slightly improved in the case where
the delta is empty, and now correctly claims not to support tags.
(Andrea Bolognani)
* Shelve can now shelve changes to a symlink target.
(James Westby, #341558)
* The help for the ``info`` command has been corrected.
(Ian Clatworthy, #351931)
* Upgrade will now use a sensible default format if the source repository
uses rich roots. (Jelmer Vernooij, #252908)
Documentation
*************
* Expanded the index of the developer documentation. (Eric Siegerman)
* New topic `bzr help debug-flags`. (Martin Pool)
* The generated manpage now explicitly lists aliases as commands.
(James Westby, #336998)
API Changes
***********
* APIs deprecated in 1.6 and previous versions of bzr are now removed.
(Martin Pool)
* ``CommitReporter`` is no longer called with ``unchanged`` status during
commit - this was a full-tree overhead that bzr no longer performs.
(Robert Collins)
* New abstract ``UIFactory`` method ``get_username`` which will be called to
obtain the username to use when connecting to remote machines.
(Jelmer Vernooij)
* New API ``Inventory.filter()`` added that filters an inventory by
a set of file-ids so that only those fileids, their parents and
their children are included. (Ian Clatworthy)
* New sort order for ``get_record_stream`` ``groupcompress`` which
sorts optimally for use with groupcompress compressors. (John Arbash
Meinel, Robert Collins)
* Repository APIs ``get_deltas_for_revisions()`` and
``get_revision_delta()`` now support an optional ``specific_fileids``
parameter. If provided, the deltas are filtered so that only those
file-ids, their parents and their children are included.
(Ian Clatworthy)
* The ``get_credentials`` and ``set_credentials`` methods of
``AuthenticationConfig`` now accept an optional realm argument.
(Jean-Francois Roy)
* The ``pb`` argument to ``fetch()`` is deprecated.
(Martin Pool)
* The ``Serializer`` class and the serializer ``format registry`` have moved
from ``bzrlib.xml_serializer`` to ``bzrlib.serializer``. (Jelmer Vernooij)
* The smart server jail now hooks into BzrDir.open to prevent any BzrDir
that is not inside the backing transport from being opened. See the
module documentation for ``bzrlib.smart.request`` for details.
(Andrew Bennetts, Robert Collins)
* ``Tree.get_symlink_target`` now always returns a unicode string result
or None. Previously it would return the bytes from reading the link
which could be in any arbitrary encoding. (Robert Collins)
Testing
*******
* ``bzrlib.tests.TestCase`` now fails the test if its own ``setUp``
and ``tearDown`` weren't called. This catches faulty tests that
forget to upcall when overriding ``setUp`` and ``tearDown``. Those
faulty tests were not properly isolated.
(Andrew Bennetts, Robert Collins)
* Fix test_msgeditor.MsgEditorTest test isolation.
(Vincent Ladeuil, #347130)
* ``medusa`` is not used anymore as an FTP test server starting with
python2.6. A new FTP test server based on ``pyftplib`` can be used
instead. This new server is a soft dependency as medusa which is still
preferred if both are available (modulo python version).
(Vincent Ladeuil)
Internals
*********
* Added ``chk_map`` for fast, trie-based storage of tuple to string maps.
(Robert Collins, John Arbash Meinel, Vincent Ladeuil)
* Added ``bzrlib.chk_map`` for fast, trie-based storage of tuple to string
maps. (Robert Collins, John Arbash Meinel, Vincent Ladeuil)
* Added ``bzrlib.inventory_delta`` module. This will be used for
serializing and deserializing inventory deltas for more efficient
streaming on the the network. (Robert Collins, Andrew Bennetts)
* ``Branch._get_config`` has been added, which splits out access to the
specific config file from the branch. This is used to let RemoteBranch
avoid constructing real branch objects to access configuration settings.
(Robert Collins, Andrew Bennetts)
* ``Branch`` now implements ``set_stacked_on_url`` in the base class as
the implementation is generic and should impact foreign formats. This
helps performance for ``RemoteBranch`` push operations to new stacked
branches. (Robert Collins, Andrew Bennetts)
* ``BtreeIndex._spill_mem_keys_to_disk()`` now generates disk index with
optmizations turned off. This only has effect when processing > 100,000
keys during something like ``bzr pack``. (John Arbash Meinel)
* ``bzr selftest`` now accepts ``--subunit`` to run in subunit output
mode. Requires ``lp:subunit`` installed to work, but is not a hard
dependency. (Robert Collins)
* ``BzrDir.open_branch`` now takes an optional ``ignore_fallbacks``
parameter for controlling opening of stacked branches.
(Andrew Bennetts, Robert Collins)
* ``CommitBuilder`` has a new method, ``record_iter_changes`` which works
in terms of an iter_changes iterator rather than full tree scanning.
(Robert Collins)
* ``DirState`` can now be passed a custom ``SHA1Provider`` object
enabling it to store the SHA1 and stat of the canonical (post
content filtered) form. (Ian Clatworthy)
* New ``assertLength`` method based on one Martin has squirreled away
somewhere. (Robert Collins, Martin Pool)
* New hook ``BzrDir.pre_open`` which runs before opening ``BzrDir``
objects, allowing better enforcement of the smart server jail when
dealing with stacked branches. (Robert Collins, Andrew Bennetts)
* New hook ``RioVersionInfoBuilder.revision``, allowing extra entries
to be added to the stanza that is printed for a particular revision.
(Jelmer Vernooij)
* New repository method ``refresh_data`` to cause any repository to
make visible data inserted into the repository by a smart server
fetch operation. (Robert Collins, Andrew Bennetts)
* ``register_filter_stack_map`` now takes an optional fallback parameter,
a callable to invoke if a preference has a value not in the map
of filter stacks. This enhancement allows, for example, bzr-svn to
handle existing svn properties that define a list of keywords to be
expanded. (Ian Clatworthy)
* ``RemoteBranchConfig`` will use a new verb ``Branch.set_config_option``
to write config settings to smart servers that support this, saving
5 round trips on the stacked streaming acceptance test.
(Robert Collins, Andrew Bennetts)
* ``RemoteBranch`` now provides ``_get_config`` for access to just the
branch specific configuration from a remote server, which uses the
already existing ``Branch.get_config_file`` smart verb.
(Robert Collins, Andrew Bennetts)
* ``RemoteRepository`` will now negatively cache missing revisions during
``get_parent_map`` while read-locked. Write-locks are unaffected.
(Robert Collins, Andrew Bennetts)
* Removed ``InterRemoteToOther``, ``InterOtherToRemote`` and
``InterPackToRemotePack`` classes, as they are now unnecessary.
(Andrew Bennetts)
* ``RepositoryFormat`` as a new attribute ``fast_deltas`` to indicate
whether the repository can efficiently generate deltas between trees
regardless of tree size. (Robert Collins)
* ``Repository.iter_files_bytes()`` now properly returns an "iterable of
byte strings" (aka 'chunked') for the content. It previously was
returning a plain string, which worked, but performed very poorly when
building a working tree (file.writelines(str) is very inefficient). This
can have a large effect on ``bzr checkout`` times. (John Arbash Meinel)
* selftest now supports a --parallel option, with values of 'fork' or
'subprocess' to run the test suite in parallel. Currently only linux
machine work, other platforms need patches submitted. (Robert Collins,
Vincent Ladeuil)
* ``tests.run_suite`` has a new parameter ``suite_decorators``, a list of
callables to use to decorate the test suite. Such decorators can add or
remove tests, or even remote the test suite to another machine if
desired. (Robert Collins)
* The smart server verb ``Repository.get_parent_map`` can now include
information about ghosts when the special revision ``include-missing:``
is in the requested parents map list. With this flag, ghosts are
included as ``missing:REVISION_ID``. (Robert Collins, Andrew Bennetts)
* ``_walk_to_common_revisions`` will now batch up at least 50
revisions before calling ``get_parent_map`` on the target,
regardless of ``InterRepository``.
(Andrew Bennetts, Robert Collins)
---------------------
A couple regessions where found in the 1.13 release. The pyrex-generated C
extensions are missing from the .tar.gz and .zip files. Documentation on how
to generate GNU ChangeLogs is wrong.
BUG FIXES:
* Change ``./bzr``'s ``_script_version`` to match ./bzrlib/__init__.py
version_info. (Bob Tanner, Martin Pool, #345232)
* Distribution archives for 1.13 do not contain generated C extension
modules (Jean-Francois Roy, Bob Tanner, #344465)
* GNU ChangeLog output can now be produced by bzr log --format
gnu-changelog is incorrect (Deejay, Bob Tanner, Martin Pool,
Robert Collins, #343928)
* ``merge --force`` works again. (Robert Collins, #342105)
---------------------------------------------
This release includes bug fixes and a few performance and feature improvements.
GNU Changelog output can now be produced by ``bzr log --format gnu-changelog``.
Debug flags can now be set in ``~/.bazaar/bazaar.conf``. Lightweight Checkouts
and Stacked Branches should both be much faster over remote connections.
CHANGES FROM bzr 1.13rc1 2009-03-10:
BUG FIXES:
* Fix "is not a stackable format" error when pushing a
stackable-format branch with an unstackable-format repository to a
destination with a default stacking policy. (Andrew Bennetts)
* Progress bars now show the rate of network activity for
``bzr+ssh://`` and ``bzr://`` connections. (Andrew Bennetts)
COMPATIBILITY BREAKS:
* ``bzr log --line`` now indicates which revisions are merges with
`[merge]` after the date. Scripts which parse the output of this
command may need to be adjusted.
(Neil Martinsen-Burrell)
NEW FEATURES:
* ``bzr reconfigure`` now supports --with-trees and --with-no-trees
options to change the default tree-creation policy of shared
repositories. (Matthew Fuller, Marius Kruger, #145033)
* Debug flags can now be set in ``~/.bazaar/bazaar.conf``.
(Martin Pool)
* Filtered views provide a mask over the tree so that users can focus
on a subset of a tree when doing their work. See ``Filtered views``
in chapter 7 of the User Guide and ``bzr help view`` for details.
(Ian Clatworthy)
* GNU Changelog output can now be produced by ``bzr log --format
gnu-changelog``. (Andrea Bolognani, Martin Pool)
* The ``-Dmemory`` flag now gives memory information on Windows.
(John Arbash Meinel)
* Multiple authors for a commit can now be recorded by using the "--author"
option multiple times. (James Westby, #185772)
* New clean-tree command, from bzrtools. (Aaron Bentley, Jelmer Vernoij)
* New command ``bzr launchpad-open`` opens a Launchpad web page for that
branch in your web browser, as long as the branch is on Launchpad at all.
(Jonathan Lange)
IMPROVEMENTS:
* ``bzr add`` no longer prints ``add completed`` on success. Failure
still prints an error message. (Robert Collins)
* ``bzr branch`` now has a ``--no-tree`` option which turns off the
generation of a working tree in the new branch.
(Daniel Watkins, John Klinger, #273993)
* Bazaar will now point out ``bzr+ssh://`` to the user when they
use ssh://. (Jelmer Vernooij, #330535)
* ``bzr -v info`` now omits the number of committers branch statistic,
making it many times faster for large projects. To include that
statistic in the output, use ``bzr -vv info``.
(Ian Clatworthy)
* ``bzr push`` to a ``bzr`` url (``bzr://``, ``bzr+ssh://`` etc) will
stream if the server is version 1.13 or greater, reducing roundtrips
significantly. (Andrew Bennetts, Robert Collins)
* Lightweight Checkouts and Stacked Branches should both be much
faster over remote connections. Building the working tree now
batches up requests into approx 5MB requests, rather than a separate
request for each file. (John Arbash Meinel)
* Support for GSSAPI authentication when using HTTP or HTTPS.
(Jelmer Vernooij)
* The ``bzr shelve`` prompt now includes a '?' help option to explain the
short options better. (Daniel Watkins, #327429)
* ``bzr lp-open`` now falls back to the push location if it cannot find a
public location. (Jonathan Lange, #332372)
* ``bzr lp-open`` will try to find the Launchpad URL for the location
passed on the command line. This makes ``bzr lp-open lp:foo`` work as
expected. (Jonathan Lange, #332705)
* ``bzr send`` now supports MH-E via ``emacsclient``. (Eric Gillespie)
BUG FIXES:
* Bazaar now gives a better message including the filename if it's
unable to read a file in the working directory, for example because
of a permission error. (Martin Pool, #338653)
* ``bzr send`` help is more specific about how to apply merge
directives. (Neil Martinsen-Burrell, #253470)
* ``bzr missing`` now uses ``Repository.get_revision_delta()`` rather
than fetching trees and determining a delta itself. (Jelmer
Vernooij, #315048)
* ``bzr push`` to a smart server no longer causes "Revision
{set([('null:',)])} not present ..." errors when the branch has
multiple root revisions. (Andrew Bennetts, #317654)
* ``bzr shelve`` now properly handle patches with no terminating newline.
(Benoît PIERRE, #303569)
* ``bzr unshelve`` gives a more palatable error if passed a non-integer
shelf id. (Daniel Watkins)
* Export now handles files that are not present in the tree.
(James Westby, #174539)
* Fixed "sprout() got an unexpected keyword argument 'source_branch'"
error branching from old repositories.
(Martin Pool, #321695)
* Make ``bzr push --quiet <non-local location>`` less chatty.
(Kent Gibson, #221461)
* Many Branch hooks would not fire with ``bzr://`` and ``bzr+ssh://``
branches, and this was not noticed due to a bug in the test logic
for branches. This is now fixed and a test added to prevent it
reoccuring. (Robert Collins, Andrew Bennetts)
* Restore the progress bar on Windows. We were disabling it when TERM
wasn't set, but Windows doesn't set TERM. (Alexander Belchenko)
* ``setup.py build_ext`` now gives a proper error when an extension
fails to build. (John Arbash Meinel)
* Symlinks to non ascii file names are now supported.
(Robert Collins, Vincent Ladeuil, #339055, #272444)
* Under rare circumstances (aka nobody reported a bug about it), the ftp
transport could revert to ascii mode. It now stays in binary mode except
when needed.
(Vincent Ladeuil)
* Unshelve does not generate warnings about progress bars.
(Aaron Bentley, #328148)
DOCUMENTATION:
* Added ``Organizing your workspace`` to the User Guide appendices,
summarizing some common ways of organizing trees, branches and
repositories and the processes/workflows implied/enabled by each.
(Ian Clatworthy)
* Hooks can now be self documenting. ``bzrlib.hooks.Hooks.create_hook``
is the entry point for this feature. (Robert Collins)
* The documentation for ``shelve`` and ``unshelve`` has been clarified.
(Daniel Watkins, #327421, #327425)
API CHANGES:
* ``bzr selftest`` now fails if the bazaar sources contain trailing
whitespace, non-unix style line endings and files not ending in a
newline. About 372 files and 3243 lines with trailing whitespace was
updated to comply with this. The code already complied with the other
criteria, but now it is enforced. (Marius Kruger)
* ``Branch.fetch`` and ``Repository.fetch`` now return None rather
than a count of copied revisions and failed revisions. A while back
we stopped ever reporting failed revisions because we started
erroring instead, and the copied revisions count is not used in the
UI at all - indeed it only reflects the repository status not
changes to the branch itself. (Robert Collins)
* MutableTree.commit now favours the "authors" argument, with the old
"author" argument being deprecated.
* Remove deprecated EmptyTree. (Martin Pool)
* ``Repository.fetch`` now accepts an optional ``fetch_spec``
parameter. A ``SearchResult`` or ``MiniSearchResult`` may be passed
to ``fetch_spec`` instead of a ``last_revision`` to specify exactly
which revisions to fetch. (Andrew Bennetts)
* ``RepositoryAcquisitionPolicy.acquire_repository`` now returns a
tuple of ``(repository, is_new_flag)``, rather than just the
repository. (Andrew Bennetts)
* Revision.get_apparent_author() is now deprecated, replaced by
Revision.get_apparent_authors(), which returns a list. The former
now returns the first item that would be returned from the second.
* The ``BranchBuilder`` test helper now accepts a ``timestamp``
parameter to ``build_commit`` and ``build_snapshot``. (Martin Pool)
* The ``_fetch_*`` attributes on ``Repository`` are now on
``RepositoryFormat``, more accurately reflecting their intent (they
describe a disk format capability, not state of a particular
repository of that format). (Robert Collins)
INTERNALS:
* Branching from a non-stacked branch on a smart protocol is now
free of virtual file system methods.
(Robert Collins, Andrew Bennetts)
* Branch and Repository creation on a bzr+ssh://server are now done
via RPC calls rather than VFS calls, reducing round trips for
pushing new branches substantially. (Robert Collins)
* ``Branch.clone`` now takes the ``repository_policy`` formerly used
inside ``BzrDir.clone_on_transport``, allowing stacking to be
configured before the branch tags and revision tip are set. This
fixes a race condition cloning stacked branches that would cause
plugins to have hooks called on non-stacked instances.
(Robert Collins, #334187)
* ``BzrDir.cloning_metadir`` now has a RPC call. (Robert Collins)
* ``BzrDirFormat.__str__`` now uses the human readable description
rather than the sometimes-absent disk label. (Robert Collins)
* ``bzrlib.fetch`` is now composed of a sender and a sink component
allowing for decoupling over a network connection. Fetching from
or into a RemoteRepository with a 1.13 server will use this to
stream the operation.
(Andrew Bennetts, Robert Collins)
* ``bzrlib.tests.run_suite`` accepts a runner_class parameter
supporting the use of different runners. (Robert Collins)
* Change how file_ids and revision_ids are interned as part of
inventory deserialization. Now we use the real ``intern()``, rather
than our own workaround that would also cache a Unicode copy of the
string, and never emptied the cache. This should slightly reduce
memory consumption. (John Arbash Meinel)
* New branch method ``create_clone_on_transport`` that returns a
branch object. (Robert Collins)
* New hook Commands['extend_command'] to allow plugins to access a
command object before the command is run (or help generated from
it), without overriding the command. (Robert Collins)
* New version of the ``BzrDir.find_repository`` verb supporting
``_network_name`` to support removing more _ensure_real calls.
(Robert Collins)
* ``RemoteBranchFormat`` no longer claims to have a disk format string.
(Robert Collins)
* ``Repository`` objects now have ``suspend_write_group`` and
``resume_write_group`` methods. These are currently only useful
with pack repositories. (Andrew Bennetts, Robert Collins)
* ``BzrDirFormat``, ``BranchFormat`` and ``RepositoryFormat`` objects
now have a ``network_name`` for passing the format across RPC calls.
(Robert Collins, Andrew Bennetts)
* ``RepositoryFormat`` objects now all have a new attribute
``_serializer`` used by fetch when reserialising is required.
(Robert Collins, Andrew Bennetts)
* Some methods have been pulled up from ``BzrBranch`` to ``Branch``
to aid branch types that are not bzr branch objects (like
RemoteBranch). (Robert Collins, Andrew Bennetts)
* Test adaptation has been made consistent throughout the built in
tests. ``TestScenarioApplier``, ``multiply_tests_from_modules``,
``adapt_tests``, ``adapt_modules`` have all been deleted. Please
use ``multiply_tests``, or for lower level needs ``apply_scenarios``
and ``apply_scenario``. (Robert Collins)
* ``TestSkipped`` is now detected by TestCase and passed to the
``TestResult`` by calling ``addSkip``. For older TestResult objects,
where ``addSkip`` is not available, ``addError`` is still called.
This permits test filtering in subunit to strip out skipped tests
resulting in a faster fix-shrink-list-run cycle. This is compatible
with the testtools protocol for skips. (Robert Collins)
* The ``_index`` of ``KnitVersionedFiles`` now supports the ability
to scan an underlying index that is going to be incorporated into
the ``KnitVersionedFiles`` object, to determine if it has missing
delta references. The method is ``scan_unvalidated_index``.
(Andrew Bennetts, Robert Collins)
* There is a RemoteSink object which handles pushing to smart servers.
(Andrew Bennetts, Robert Collins)
* ``TransportTraceDecorator`` now logs ``put_bytes_non_atomic`` and
``rmdir`` calls. (Robert Collins)
* ``VersionedFiles`` record adapters have had their signature change
from ``(record, record.get_bytes_as(record.storage_kind))`` to
``(record)`` reducing excess duplication and allowing adapters
to access private data in record to obtain content more
efficiently. (Robert Collins)
* We no longer probe to see if we should create a working tree during
clone if we cannot get a local_abspath for the new bzrdir.
(Robert Collins)
--------------------------------
This release of Bazaar contains many improvements to the speed,
documentation and functionality of ``bzr log`` and the display of logged
revisions by ``bzr status``. bzr now also gives a better indication of
progress, both in the way operations are drawn onto a text terminal, and
by showing the rate of network IO.
BUG FIXES:
* ``bzr init --development-wt5[-rich-root]`` would fail because of
circular import errors. (John Arbash Meinel, #328135)
DOCUMENTATION:
* Expanded the help for log and added a new help topic called
``log-formats``. (Ian Clatworthy)
bzr 1.12rc1 "1234567890" 2009-02-10
-----------------------------------
COMPATIBILITY BREAKS:
* By default, ``bzr status`` after a merge now shows just the pending
merge tip revisions. This improves the signal-to-noise ratio after
merging from trunk and completes much faster. To see all merged
revisions, use the new ``-v`` flag. (Ian Clatworthy)
* ``bzr log --line`` now shows any tags after the date and before
the commit message. If you have scripts which parse the output
from this command, you may need to adjust them accordingly.
(Ian Clatworthy)
* ``bzr log --short`` now shows any additional revision properties
after the date and before the commit message. Scripts that parse
output of the log command in this situation may need to adjust.
(Neil Martinsen-Burrell)
* The experimental formats ``1.12-preview`` and ``1.12-preview-rich-root``
have been renamed ``development-wt5`` and ``development-wt5-rich-root``
respectively, given they are not ready for release in 1.12.
(Ian Clatworthy)
NEW FEATURES:
* Add support for filtering ``bzr missing`` on revisions. Remote revisions
can be filtered using ``bzr missing -r -20..-10`` and local revisions can
be filtered using ``bzr missing --my-revision -20..-10``.
(Marius Kruger)
* ``bzr log -p`` displays the patch diff for each revision.
When logging a file, the diff only includes changes to that file.
(Ian Clatworthy, #202331, #227335)
* ``bzr log`` supports a new option called ``-n N`` or ``--level N``.
A value of 0 (zero) means "show all nested merge revisions" while
a value of 1 (one) means "show just the top level". Values above
1 can be used to see a limited amount of nesting. That can be
useful for seeing the level or two below PQM submits for example.
To force the ``--short`` and ``--line`` formats to display all nested
merge revisions just like ``--long`` does by default, use a command
like ``bzr log --short -n0``. To display just the mainline using
``--long`` format, ``bzr log --long -n1``.
(Ian Clatworthy)
IMPROVEMENTS:
* ``bzr add`` more clearly communicates success vs failure.
(Daniel Watkins)
* ``bzr init`` will now print a little less verbose output.
(Marius Kruger)
* ``bzr log`` is now much faster in many use cases, particularly
at incrementally displaying results and filtering by a
revision range. (Ian Clatworthy)
* ``bzr log --short`` and ``bzr log --line`` now show tags, if any,
for each revision. The tags are shown comma-separated inside
``{}``. For short format, the tags appear at the end of line
before the optional ``[merge]`` indicator. For line format,
the tags appear after the date. (Ian Clatworthy)
* Progress bars now show the rate of activity for some sftp
operations, and they are drawn different. (Martin Pool, #172741)
* Progress bars now show the rate of activity for urllib and pycurl based
http client implementations. The operations are tracked at the socket
level for better precision.
(Vincent Ladeuil)
* Rule-based preferences can now accept multiple patterns for a set of
rules. (Marius Kruger)
* The ``ancestor:`` revision spec will now default to referring to the
parent of the branch if no other location is given.
(Daniel Watkins, #198417)
* The debugger started as a result of setting ``$BZR_PDB`` works
around a bug in ``pdb``, http://bugs.python.org/issue4150. The bug
can cause truncated tracebacks in Python versions before 2.6.
(Andrew Bennetts)
* VirtualVersionedFiles now implements
``iter_lines_added_or_present_in_keys``. This allows the creation of
new branches based on stacked bzr-svn branches. (#311997)
BUG FIXES:
* ``bzr annotate --show-ids`` doesn't give a backtrace on empty files
anymore.
(Anne Mohsen, Vincent Ladeuil, #314525)
* ``bzr log FILE`` now correctly shows mainline revisions merging
a change to FILE when the ``--short`` and ``--line`` log formats
are used. (Ian Clatworthy, #317417)
* ``bzr log -rX..Y FILE`` now shows the history of FILE provided
it existed in Y or X, even if the file has since been deleted or
renamed. If no range is given, the current/basis tree and
initial tree are searched in that order. More generally, log
now interprets filenames in their historical context.
(Ian Clatworthy, #175520)
* ``bzr status`` now reports nonexistent files and continues, then
errors (with code 3) at the end. (Karl Fogel, #306394)
* Don't require the present compression base in knits to be the same
when adding records in knits. (Jelmer Vernooij, #307394)
* Fix a problem with CIFS client/server lag on Windows colliding with
an invariant-per-process algorithm for generating AtomicFile names
(Adrian Wilkins, #304023)
* Many socket operations now handle EINTR by retrying the operation.
Previously EINTR was treated as an unrecoverable failure. There is
a new ``until_no_eintr`` helper function in ``bzrlib.osutils``.
(Andrew Bennetts)
* Support symlinks with non-ascii characters in the symlink filename.
(Jelmer Vernooij, #319323)
* There was a bug in how we handled resolving when a file is deleted
in one branch, and modified in the other. If there was a criss-cross
merge, we would cause the deletion to conflict a second time.
(Vincent Ladeuil, John Arbash Meinel)
* There was another bug in how we chose the correct intermediate LCA in
criss-cross merges leading to several kind of changes be incorrectly
handled.
(John Arbash Meinel, Vincent Ladeuil)
* Unshelve now handles deleted paths without crashing. (Robert Collins)
DOCUMENTATION:
* Improved plugin developer documentation. (Martin Pool)
API CHANGES:
* ``ProgressBarStack`` is deprecated; instead use
``ui_factory.nested_progress_bar`` to create new progress bars.
(Martin Pool)
* ForeignVcsMapping() now requires a ForeignVcs object as first
argument. (Jelmer Vernooij)
* ForeignVcsMapping.show_foreign_revid() has been moved to
ForeignVcs. (Jelmer Vernooij)
* ``read_bundle_from_url`` is deprecated in favor of
``read_mergeable_from_url``. (Vincent Ladeuil)
* Revision specifiers are now registered in
``bzrlib.revisionspec.revspec_registry``, and the old list of
revisionspec classes (``bzrlib.revisionspec.SPEC_TYPES``) has been
deprecated. (Jelmer Vernooij, #321183)
* The progress and UI classes have changed; the main APIs remain the
same but code that provides a new UI or progress bar class may
need to be updated. (Martin Pool)
INTERNALS:
* Default User Interface (UI) is CLIUIFactory when bzr runs in a dumb
terminal. It is sometimes desirable do override this default by forcing
bzr to use TextUIFactory. This can be achieved by setting the
BZR_USE_TEXT_UI environment variable (emacs shells, as opposed to
compile buffers, are such an example).
(Vincent Ladeuil)
* New API ``Branch.iter_merge_sorted_revisions()`` that iterates over
``(revision_id, depth, revno, end_of_merge)`` tuples.
(Ian Clatworthy)
* New ``Branch.dotted_revno_to_revision_id()`` and
``Branch.revision_id_to_dotted_revno()`` APIs that pick the most
efficient way of doing the mapping.
(Ian Clatworthy)
* Refactor cmd_serve so that it's a little easier to build commands that
extend it, and perhaps even a bit easier to read. (Jonathan Lange)
* ``TreeDelta.show()`` now accepts a ``filter`` parameter allowing log
formatters to retrict the output.
(Vincent Ladeuil)
------------------------------
This first monthly release of Bazaar for 2009 improves Bazaar's operation
in Windows, Mac OS X, and other situations where file names are matched
without regard to capitalization: Bazaar tries to match the case of an
existing file. This release of Bazaar also improves the efficiency of
Tortoise Windows Shell integration and lets it work on 64-bit platforms.
The UI through which Bazaar supports historic formats has been improved,
so 'bzr help formats' now gives a simpler and shorter list, with clear
advice.
This release also fixes a number of bugs, particularly a glitch that can
occur when there are concurrent writes to a pack repository.
BUG FIXES:
* Fix failing test when CompiledChunksToLines is not available.
(Vincent Ladeuil)
* Stacked branches don't repeatedly open their transport connection.
(John Arbash Meinel)
bzr 1.11rc1 "Eyes up!" 2009-01-09
---------------------------------
CHANGES:
* Formats using Knit-based repository formats are now explicitly
marked as deprecated. (Ian Clatworthy)
NEW FEATURES:
* Add support for `bzr tags -r 1..2`, that is we now support showing
tags applicable for a specified revision range. (Marius Kruger)
* ``authentication.conf`` now accepts pluggable read-only credential
stores. Such a plugin (``netrc_credential_store``) is now included,
handles the ``$HOME/.netrc`` file and can server as an example to
implement other plugins.
(Vincent Ladeuil)
* ``shelve --list`` can now be used to list shelved changes.
(Aaron Bentley)
IMPROVEMENTS:
* Add trailing slash to directories in all output of ``bzr ls``, except
``bzr ls --null``. (Gordon P. Hemsley, #306424)
* ``bzr revision-info`` now supports a -d option to specify an
alternative branch. (Michael Hudson)
* Add connection to a C++ implementation of the Windows Shell Extension
which is able to fully replace the current Python implemented one.
Advantages include 64bit support and reduction in overhead for
processes which drag in shell extensions.
(Mark Hammond)
* Support the Claws mail client directly, rather than via
xdg-email. This prevents the display of an unnecessary modal
dialog in Claws, informing the user that a file has been
attached to the message, and works around bug #291847 in
xdg-utils which corrupts the destination address.
* When working on a case-insensitive case-preserving file-system, as
commonly found with Windows, bzr will often ignore the case of the
arguments specified by the user in preference to the case of an existing
item on the file-system or in the inventory to help prevent
counter-intuitive behaviour on Windows. (Mark Hammond)
BUG FIXES:
* Allow BzrDir implementation to implement backing up of
control directory. (#139691)
* ``bzr push`` creating a new stacked branch will now only open a
single connection to the target machine. (John Arbash Meinel)
* Don't call iteritems on transport_list_registry, because it may
change during iteration. (Martin Pool, #277048)
* Don't make a broken branch when pushing an unstackable-format branch
that's in a stackable shared repository to a location with default
stack-on location. (Andrew Bennetts, #291046)
* Don't require embedding user in HTTP(S) URLs do use authentication.conf.
(Ben Jansen, Vincent Ladeuil, #300347)
* Fix a problem with CIFS client/server lag on windows colliding with
an invariant-per-process algorithm for generating AtomicFile names
(Adrian Wilkins, #304023)
* Fix bogus setUp signature in UnavailableFTPServer.
(Gary van der Merwe, #313498)
* Fix compilation error in ``_dirstate_helpers_c`` on SunOS/Solaris.
(Jari Aalto)
* Fix SystemError in ``_patiencediff_c`` module by calling
PyErr_NoMemory() before returning NULL in PatienceSequenceMatcher_new.
(Andrew Bennetts, #303206)
* Give proper error message for diff with non-existent dotted revno.
(Marius Kruger, #301969)
* Handle EACCES (permission denied) errors when launching a message
editor, and emit warnings when a configured editor cannot be
started. (Andrew Bennetts)
* ``$HOME/.netrc`` file is now recognized as a read-only credential store
if configured in ``authentication.conf`` with 'password_encoding=netrc'
in the appropriate sections.
(Vincent Ladeuil, #103029)
* Opening a stacked branch now properly shares the connection, rather
than opening a new connection for the stacked-on branch.
(John Arbash meinel)
* Preserve transport decorators while following redirections.
(Vincent Ladeuil, #245964, #270863)
* Provides a finer and more robust filter for accepted redirections.
(Vincent Ladeuil, #303959, #265070)
* ``shelve`` paths are now interpreted relative to the current working
tree. (Aaron Bentley)
* ``Transport.readv()`` defaults to not reading more than 100MB in a
single array. Further ``RemoteTransport.readv`` sets this to 5MB to
work better with how it splits its requests.
(John Arbash Meinel, #303538)
* Pack repositories are now able to reload the pack listing and retry
the current operation if another action causes the data to be
repacked. (John Arbash Meinel, #153786)
* ``pull -v`` now respects the log_format configuration variable.
(Aaron Bentley)
* ``push -v`` now works on non-initial pushes. (Aaron Bentley)
* Use the short status format when the short format is used for log.
(Vincent Ladeuil, #87179)
* Allow files to be renamed or moved via remove + add-by-id. (Charles
Duffy, #314251)
DOCUMENTATION:
* Improved the formats help topic to explain why multiple formats
exist and to provide guidelines in selecting one. Introduced
two new supporting help topics: current-formats and other-formats.
(Ian Clatworthy)
API CHANGES:
* ``LRUCache(after_cleanup_size)`` was renamed to
``after_cleanup_count`` and the old name deprecated. The new name is
used for clarity, and to avoid confusion with
``LRUSizeCache(after_cleanup_size)``. (John Arbash Meinel)
* New ``ForeignRepository`` base class, to help with foreign branch
support (e.g. svn). (Jelmer Vernooij)
* ``node_distances`` and ``select_farthest`` can no longer be imported
from ``bzrlib.graph``. They can still be imported from
``bzrlib.deprecated_graph``, which has been the preferred way to
import them since before 1.0. (Andrew Bennetts)
* The logic in commit now delegates inventory basis calculations to
the ``CommitBuilder`` object; this requires that the commit builder
in use has been updated to support the new ``recording_deletes`` and
``record_delete`` methods. (Robert Collins)
TESTING:
* An HTTPS server is now available (it requires python-2.6). Future bzr
versions will allow the use of the python-2.6 ssl module that can be
installed for 2.5 and 2.4.
* ``bzr selftest`` now fails if new trailing white space is added to
the bazaar sources. It only checks changes not committed yet. This
means that PQM will now reject changes that introduce new trailing
whitespace. (Marius Kruger)
* Introduced new experimental formats called ``1.12-preview`` and
``1.12-preview-rich-root`` to enable testing of related pending
features, namely content filtering and filtered views.
(Ian Clatworthy)
INTERNALS:
* Added an ``InventoryEntry`` cache when deserializing inventories.
Can cut the time to iterate over multiple RevisionsTrees in half.
(John Arbash Meinel)
* Added ``bzrlib.fifo_cache.FIFOCache`` which is designed to have
minimal overhead versus using a plain dict for cache hits, at the
cost of not preserving the 'active' set as well as an ``LRUCache``.
(John Arbash Meinel)
* ``bzrlib.patience_diff.unified_diff`` now properly uses a tab
character to separate the filename from the date stamp, and doesn't
add trailing whitespace when a date stamp is not supplied.
(Adeodato Simó, John Arbash Meinel)
* ``DirStateWorkingTree`` and ``DirStateWorkingTreeFormat`` added
as base classes of ``WorkingTree4`` and ``WorkingTreeFormat4``
respectively. (Ian Clatworthy)
* ``KnitVersionedFiles._check_should_delta()`` now uses the
``get_build_details`` api to avoid multiple hits to the index, and
to properly follow the ``compression_parent`` rather than assuming
it is the left-hand parent. (John Arbash Meinel)
* ``KnitVersionedFiles.get_record_stream()`` will now chose a
more optimal ordering when the keys are requested 'unordered'.
Previously the order was fully random, now the records should be
returned from each pack in turn, in forward I/O order.
(John Arbash Meinel)
* ``mutter()`` will now flush the ``~/.bzr.log`` if it has been more
than 2s since the last time it flushed. (John Arbash Meinel)
* New method ``bzrlib.repository.Repository.add_inventory_by_delta``
allows adding an inventory via an inventory delta, which can be
more efficient for some repository types. (Robert Collins)
* Repository ``CommitBuilder`` objects can now accumulate an inventory
delta. To enable this functionality call ``builder.recording_deletes``
and additionally call ``builder.record_delete`` when a delete
against the basis occurs. (Robert Collins)
* The default http handler has been changed from pycurl to urllib.
The default is still pycurl for https connections. (The only
advantage of pycurl is that it checks ssl certificates.)
(John Arbash Meinel)
* ``VersionedFiles.get_record_stream()`` can now return objects with a
storage_kind of ``chunked``. This is a collection (list/tuple) of
strings. You can use ``osutils.chunks_to_lines()`` to turn them into
guaranteed 'lines' or you can use ``''.join(chunks)`` to turn it
into a fulltext. This allows for some very good memory savings when
asking for many texts that share ancestry, as the individual chunks
can be shared between versions of the file. (John Arbash Meinel)
* ``pull -v`` and ``push -v`` use new function
``bzrlib.log.show_branch_change`` (Aaron Bentley)
-------------------
Bazaar 1.10 has several performance improvements for copying revisions
(especially for small updates to large projects). There has also been a
significant amount of effort in polishing stacked branches. The commands
``shelve`` and ``unshelve`` have become core commands, with an improved
implementation.
The only changes versus bzr-1.10rc1 are bugfixes for stacked branches.
BUG FIXES:
* Don't set a pack write cache size from RepoFetcher, because the
cache is not coherent with reads and causes ShortReadvErrors.
This reverses the change that fixed#294479.
(Martin Pool, #303856)
* Properly handle when a revision can be inserted as a delta versus
when it needs to be expanded to a fulltext for stacked branches.
There was a bug involving merge revisions. As a method to help
prevent future difficulties, also make stacked fetches sort
topologically. (John Arbash Meinel, #304841)
bzr 1.10rc1 2008-11-28
----------------------
This release of Bazaar focuses on performance improvements when pushing
and pulling revisions, both locally and to remote networks. The popular
``shelve`` and ``unshelve`` commands, used to interactively revert and
restore work in progress, have been merged from bzrtools into the bzr
core. There are also bug fixes for portability, and for stacked branches.
NEW FEATURES:
* New ``commit_message_template`` hook that is called by the commit
code to generate a template commit message. (Jelmer Vernooij)
* New `shelve` and `unshelve` commands allow undoing and redoing changes.
(Aaron Bentley)
IMPROVEMENTS:
* ``(Remote)Branch.copy_content_into`` no longer generates the full revision
history just to set the last revision info.
(Andrew Bennetts, John Arbash Meinel)
* Fetches between formats with different serializers (such as
pack-0.92-subtree and 1.9-rich-root) are faster now. This is due to
operating on batches of 100 revisions at time rather than
one-by-one. (Andrew Bennetts, John Arbash Meinel)
* Search index files corresponding to pack files we've already used
before searching others, because they are more likely to have the
keys we're looking for. This reduces the number of iix and tix
files accessed when pushing 1 new revision, for instance.
(John Arbash Meinel)
* Signatures to transfer are calculated more efficiently in
``item_keys_introduced_by``. (Andrew Bennetts, John Arbash Meinel)
* The generic fetch code can once again copy revisions and signatures
without extracting them completely to fulltexts and then serializing
them back down into byte strings. This is a significant performance
improvement when fetching from a stacked branch.
(John Arbash Meinel, #300289)
* When making a large readv() request over ``bzr+ssh``, break up the
request into more manageable chunks. Because the RPC is not yet able
to stream, this helps keep us from buffering too much information at
once. (John Arbash Meinel)
BUG FIXES:
* Better message when the user needs to set their Launchpad ID.
(Martin Pool, #289148)
* ``bzr commit --local`` doesn't access the master branch anymore.
This fixes a regression introduced in 1.9. (Marius Kruger, #299313)
* Don't call the system ``chdir()`` with an empty path. Sun OS seems
to give an error in that case. Also, don't count on ``getcwd()``
being able to allocate a new buffer, which is a gnu extension.
(John Arbash Meinel, Martin Pool, Harry Hirsch, #297831)
* Don't crash when requesting log --forward <file> for a revision range
starting with a dotted revno.
(Vincent Ladeuil, #300055)
* Don't create text deltas spanning stacked repositories; this could
cause "Revision X not present in Y" when later accessing them.
(Martin Pool, #288751)
* Pack repositories are now able to reload the pack listing and retry
the current operation if another action causes the data to be
repacked. (John Arbash Meinel, #153786)
* PermissionDenied errors from smart servers no longer cause
"PermissionDenied: "None"" on the client.
(Andrew Bennetts, #299254)
* Pushing to a stacked pack repository now batches writes, the same
way writes are batched to ordinary pack repository. This makes
pushing to a stacked branch over the network much faster.
(Andrew Bennetts, #294479)
* TooManyConcurrentRequests no longer occur when a fetch fails and
tries to abort a write group. This allows the root cause (e.g. a
network interruption) to be reported. (Andrew Bennetts, #297014)
* RemoteRepository.get_parent_map now uses fallback repositories.
(Aaron Bentley, #297991?, #293679?)
API CHANGES:
* ``CommitBuilder`` now validates the strings it will be committing,
to ensure that they do not have characters that will not be properly
round-tripped. For now, it just checks for characters that are
invalid in the XML form. (John Arbash Meinel, #295161)
* Constructor parameters for NewPack (internal to pack repositories)
have changed incompatibly.
* ``Repository.abort_write_group`` now accepts an optional
``suppress_errors`` flag. Repository implementations that override
``abort_write_group`` will need to be updated to accept the new
argument. Subclasses that only override ``_abort_write_group``
don't need to change.
* Transport implementations must provide copy_tree_to_transport. A default
implementation is provided for Transport subclasses.
TESTING:
* ``bzr selftest`` now fails if no doctests are found in a module
that's expected to have them. (Martin Pool)
* Doctests now only report the first failure. (Martin Pool)
