- update to:
bzr 1.5 2008-05-16
------------------
This release of Bazaar includes several updates to the documentation, and fixes
to prepare for making rich root support the default format. Many bugs have been
squashed, including fixes to log, bzr+ssh inter-operation with older servers.
CHANGES:
* Suppress deprecation warnings when bzrlib is a 'final' release. This way
users of packaged software won't be bothered with DeprecationWarnings,
but developers and testers will still see them. (John Arbash Meinel)
DOCUMENTATION:
* Incorporate feedback from Jelmer Vernooij and Neil Martinsen-Burrell
on the plugin and integration chapters of the User Guide.
(Ian Clatworthy)
bzr 1.5rc1 2008-05-09
---------------------
NOTES WHEN UPGRADING:
CHANGES:
* Broader support of GNU Emacs mail clients. Set
``mail_client=emacsclient`` in your bazaar.conf and ``send`` will pop the
bundle in a mail buffer according to the value of ``mail-user-agent``
variable. (Xavier Maillard)
FEATURES:
IMPROVEMENTS:
* Diff now handles revision specs like "branch:" and "submit:" more
efficiently. (Aaron Bentley)
* More friendly error given when attempt to start the smart server
on an address already in use. (Andrea Corbellini, #200575)
* Pull completes much faster when there is nothing to pull.
(Aaron Bentley)
BUGFIXES:
* Authentication.conf can define sections without password.
(Vincent Ladeuil, #199440)
* Avoid muttering every time a child update does not cause a progress bar
update. (John Arbash Meinel, #213771)
* ``Branch.reconcile()`` is now implemented. This allows ``bzr reconcile``
to fix when a Branch has a non-canonical mainline history. ``bzr check``
also detects this condition. (John Arbash Meinel, #177855)
* ``bzr commit`` now works with Microsoft's FTP service.
(Andreas Deininger)
* Catch definitions outside sections in authentication.conf.
(Vincent Ladeuil, #217650)
* Conversion from non-rich-root to rich-root(-pack) updates inventory
sha1s, even when bundles are used. (Aaron Bentley, #181391)
* Conversion from non-rich-root to rich-root(-pack) works correctly even
though search keys are not topologically sorted. (Aaron Bentley)
* Conversion from non-rich-root to rich-root(-pack) works even when a
parent revision has a different root id. (Aaron Bentley, #177874)
* Disable strace testing until strace is fixed (see bug #103133) and emit a
warning when selftest ends to remind us of leaking tests.
(Vincent Ladeuil, #226769)
* Fetching all revisions from a repository does not cause pack collisions.
(Robert Collins, Aaron Bentley, #212908)
* Fix error about "attempt to add line-delta in non-delta knit".
(Andrew Bennetts, #217701)
* Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would break
if the remote server was < version 1.2. This was due to a bug in the
RemoteRepository.get_parent_map() fallback code.
(John Arbash Meinel, #214894)
* Remove leftover code in ``bzr_branch`` that inappropriately creates
a ``branch-name`` file in the branch control directory.
(Martin Pool)
* Set SO_REUSEADDR on server sockets of ``bzr serve`` to avoid problems
rebinding the socket when starting the server a second time.
(John Arbash Meinel, Martin Pool, #164288)
* Severe performance degradation in fetching from knit repositories to
knits and packs due to parsing the entire revisions.kndx on every graph
walk iteration fixed by using the Repository.get_graph API. There was
another regression in knit => knit fetching which re-read the index for
every revision each side had in common.
(Robert Collins, John Arbash Meinel)
* When logging the changes to a particular file, there was a bug if there
were ghosts in the revision ancestry. (John Arbash Meinel, #209948)
DOCUMENTATION:
* Expanded the User Guide to include new chapters on popular plugins and
integrating Bazaar into your environment. The *Best practices* chapter
was renamed to *Miscellaneous topics* as suggested by community
feedback as well. (Ian Clatworthy)
* Document outlining strategies for TortoiseBzr. (Mark Hammond)
* Improved the documentation on hooks. (Ian Clatworthy)
* Update authentication docs regarding ssh agents.
(Vincent Ladeuil, #183705)
TESTING:
* Add ``thread_name_suffix`` parameter to SmartTCPServer_for_testing, to
make it easy to identify which test spawned a thread with an unhandled
exception. (Andrew Bennetts)
* New ``--debugflag``/``-E`` option to ``bzr selftest`` for setting
options for debugging tests, these are complementary to the the -D
options. The ``-Dselftest_debug`` global option has been replaced by the
``-E=allow_debug`` option for selftest. (Andrew Bennetts)
* Parameterised test ids are preserved correctly to aid diagnosis of test
failures. (Robert Collins, Andrew Bennetts)
* The test suite modules have been modified to define load_tests() instead
of test_suite(). That speeds up selective loading (via --load-list)
significantly and provides many examples on how to migrate (grep for
load_tests). (Vincent Ladeuil)
INTERNALS:
* ``Hooks.install_hook`` is now deprecated in favour of
``Hooks.install_named_hook`` which adds a required ``name`` parameter, to
avoid having to call ``Hooks.name_hook``. (Daniel Watkins)
* Implement xml8 serializer. (Aaron Bentley)
* New form ``@deprecated_method(deprecated_in(1, 5, 0))`` for making
deprecation wrappers. (Martin Pool)
* ``Repository.revision_parents`` is now deprecated in favour of
``Repository.get_parent_map([revid])[revid]``. (Jelmer Vernooij)
* The Python ``assert`` statement is no longer used in Bazaar source, and
a test checks this. (Martin Pool)
API BREAKS:
* ``bzrlib.status.show_pending_merges`` requires the repository to be
locked by the caller. Callers should have been doing it anyway, but it
will now raise an exception if they do not. (John Arbash Meinel)
* Repository.get_data_stream, Repository.get_data_stream_for_search(),
Repository.get_deltas_for_revsions(), Repository.revision_trees(),
Repository.item_keys_introduced_by() no longer take read locks.
(Aaron Bentley)
* ``LockableFiles.get_utf8`` is deprecated, as a start towards
removing LockableFiles and ``.control_files`` entirely.
(Martin Pool)
* Methods deprecated prior to 1.1 have been removed.
(Martin Pool)
This release of Bazaar includes handy improvements to the speed of log and
status, new options for several commands, improved documentation, and better
hooks, including initial code for server-side hooks. A number of bugs have
been fixed, particularly in interoperability between different formats or
different releases of Bazaar over there network. There's been substantial
internal work in both the repository and network code to enable new features
and faster performance.
BUG FIXES:
* Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would break
if the remote server was < version 1.2. This was due to a bug in the
RemoteRepository.get_parent_map() fallback code.
(John Arbash Meinel, Andrew Bennetts, #214894)
- assume that Python 2.4 and 2.5 are compatible and allow checking for
fallout.
- remove PYTHON_VERSIONS_COMPATIBLE that are obsoleted by the 2.3+
default. Modify the others to deal with the removals.
* Fix a bug causing a ValueError crash in ``parse_line_delta_iter`` when
fetching revisions from a knit to pack repository or vice versa using
bzr:// (including over http or ssh).
(#208418, Andrew Bennetts, Martin Pool, Robert Collins)
Many operations that act on history, including ``log`` and ``annotate`` are
now substantially faster. Several bugs have been fixed and several new
options and features have been added.
And more, please review the NEWS file.
bzr 1.2 2008-02-15 (BUGFIXES and INTERNALS omitted)
------------------
bzr 1.2rc1 2008-02-13
---------------------
NOTES WHEN UPGRADING:
* Fetching via the smart protocol may need to reconnect once during a fetch
if the remote server is running Bazaar 1.1 or earlier, because the client
attempts to use more efficient requests that confuse older servers. You
may be required to re-enter a password or passphrase when this happens.
This won't happen if the server is upgraded to Bazaar 1.2.
(Andrew Bennetts)
CHANGES:
* Fetching via bzr+ssh will no longer fill ghosts by default (this is
consistent with pack-0.92 fetching over SFTP). (Robert Collins)
* Formatting of ``bzr plugins`` output is changed to be more human-
friendly. Full path of plugins locations will be shown only with
``--verbose`` command-line option. (Alexander Belchenko)
* ``merge`` now prefers to use the submit branch, but will fall back to
parent branch. For many users, this has no effect. But some users who
pull and merge on the same branch will notice a change. This change
makes it easier to work on a branch on two different machines, pulling
between the machines, while merging from the upstream.
``merge --remember`` can now be used to set the submit_branch.
(Aaron Bentley)
FEATURES:
* ``merge --preview`` produces a diff of the changes merge would make,
but does not actually perform the merge. (Aaron Bentley)
* New smart method ``Repository.get_parent_map`` for getting revision
parent data. This returns additional parent information topologically
adjacent to the requested data to reduce round trip latency impacts.
(Robert Collins)
* New smart method, ``Repository.stream_revisions_chunked``, for fetching
revision data that streams revision data via a chunked encoding. This
avoids buffering large amounts of revision data on the server and on the
client, and sends less data to the server to request the revisions.
(Andrew Bennetts, Robert Collins, #178353)
* The launchpad plugin now handles lp urls of the form
``lp://staging/``, ``lp://demo/``, ``lp://dev/`` to use the appropriate
launchpad instance to do the resolution of the branch identities.
This is primarily of use to Launchpad developers, but can also
be used by other users who want to try out Launchpad as
a branch location without messing up their public Launchpad
account. Branches that are pushed to the staging environment
have an expected lifetime of one day. (Tim Penhey)
IMPROVEMENTS:
* Creating a new branch no longer tries to read the entire revision-history
unnecessarily over smart server operations. (Robert Collins)
* Fetching between different repository formats with compatible models now
takes advantage of the smart method to stream revisions. (Andrew Bennetts)
* The ``--coverage`` option is now global, rather specific to ``bzr
selftest``. (Andrew Bennetts)
* The ``register-branch`` command will now use the public url of the branch
containing the current directory, if one has been set and no explicit
branch is provided. (Robert Collins)
* Tweak the ``reannotate`` code path to optimize the 2-parent case.
Speeds up ``bzr annotate`` with a pack repository by approx 3:2.
(John Arbash Meinel)
API BREAKS:
* Classes implementing Merge types like Merge3Merger must now accept (and
honour) a do_merge flag in their constructor. (Aaron Bentley)
* ``Repository.add_inventory`` and ``add_revision`` now require the caller
to previously take a write lock (and start a write group.)
(Martin Pool)
TESTING:
* selftest now accepts --load-list <file> to load a test id list. This
speeds up running the test suite on a limited set of tests.
(Vincent Ladeuil)
For the full list of changes, see NEWS.
[many bugfixes]
* The syntax ``bzr diff branch1 branch2`` is no longer supported.
Use ``bzr diff branch1 --new branch2`` instead. This change has
been made to remove the ambiguity where ``branch2`` is in fact a
specific file to diff within ``branch1``.
* diff '--using' allows an external diff tool to be used for files.
(Aaron Bentley)
* New "lca" merge-type for fast everyday merging that also supports
criss-cross merges. (Aaron Bentley)
* ``merge`` now warns when merge directives cause cherrypicks.
(Aaron Bentley)
* ``split`` now supported, to enable splitting large trees into smaller
pieces. (Aaron Bentley)
* Reference material has now be moved out of the User Guide and added
to the User Reference. The User Reference has gained 4 sections as
a result: Authenication Settings, Configuration Settings, Conflicts
and Hooks. All help topics are now dumped into text format in the
doc/en/user-reference directory for those who like browsing that
information in their editor. (Ian Clatworthy)
* Annotate merge (merge-type=weave) now supports cherrypicking.
(Aaron Bentley)
* ``switch`` can now be used on heavyweight checkouts as well as
lightweight ones. After switching a heavyweight checkout, the
local branch is a mirror/cache of the new bound branch and
uncommitted changes in the working tree are merged. As a safety
check, if there are local commits in a checkout which have not
been committed to the previously bound branch, then ``switch``
fails unless the ``--force`` option is given. This option is
now also required if the branch a lightweight checkout is pointing
to has been moved. (Ian Clatworthy)
* The default repository format is now ``pack-0.92``. This
default is used when creating new repositories with ``init`` and
``init-repo``, and when branching over bzr+ssh or bzr+hpss.
(See https://bugs.launchpad.net/bugs/164626)
This format can be read and written by Bazaar 0.92 and later, and
data can be transferred to and from older formats.
To upgrade, please reconcile your repository (``bzr reconcile``), and then
upgrade (``bzr upgrade``).
``pack-0.92`` offers substantially better scaling and performance than the
previous knits format. Some operations are slower where the code already
had bad scaling characteristics under knits, the pack format makes such
operations more visible as part of being more scalable overall. We will
correct such operations over the coming releases and encourage the filing
of bugs on any operation which you observe to be slower in a packs
repository. One particular case that we do not intend to fix is pulling
data from a pack repository into a knit repository over a high latency
link; downgrading such data requires reinsertion of the file texts, and
this is a classic space/time tradeoff. The current implementation is
conservative on memory usage because we need to support converting data
from any tree without problems.
(Robert Collins, Martin Pool, #164476)
* The pack format is now accessible as "pack-0.92", or "pack-0.92-subtree"
to enable the subtree functions (for example, for bzr-svn).
See http://doc.bazaar-vcs.org/latest/developer/packrepo.html
(Martin Pool)
* New ``authentication.conf`` file holding the password or other credentials
for remote servers. This can be used for ssh, sftp, smtp and other
supported transports.
(Vincent Ladeuil)
* ``switch`` command added for changing the branch a lightweight checkout
is associated with and updating the tree to reflect the latest content
accordingly. This command was previously part of the BzrTools plug-in.
(Ian Clatworthy, Aaron Bentley, David Allouche)
* ``reconfigure`` command can now convert branches, trees, or checkouts to
lightweight checkouts. (Aaron Bentley)
* ``bzr merge`` now warns when it encounters a criss-cross merge.
(Aaron Bentley)
bzr 0.92 2007-11-05
===================
CHANGES:
* New uninstaller on Win32. (Alexander Belchenko)
bzr 0.92rc1 2007-10-29
======================
NOTES WHEN UPGRADING:
CHANGES:
* ``bzr`` now returns exit code 4 if an internal error occurred, and
3 if a normal error occurred. (Martin Pool)
* ``pull``, ``merge`` and ``push`` will no longer silently correct some
repository index errors that occured as a result of the Weave disk format.
Instead the ``reconcile`` command needs to be run to correct those
problems if they exist (and it has been able to fix most such problems
since bzr 0.8). Some new problems have been identified during this release
and you should run ``bzr check`` once on every repository to see if you
need to reconcile. If you cannot ``pull`` or ``merge`` from a remote
repository due to mismatched parent errors - a symptom of index errors -
you should simply take a full copy of that remote repository to a clean
directory outside any local repositories, then run reconcile on it, and
finally pull from it locally. (And naturally email the repositories owner
to ask them to upgrade and run reconcile).
(Robert Collins)
FEATURES:
* New ``knitpack-experimental`` repository format. This is interoperable with
the ``dirstate-tags`` format but uses a smarter storage design that greatly
speeds up many operations, both local and remote. This new format can be
used as an option to the ``init``, ``init-repository`` and ``upgrade``
commands. See http://doc.bazaar-vcs.org/latest/developers/knitpack.html
for further details. (Robert Collins)
* For users of bzr-svn (and those testing the prototype subtree support) that
wish to try packs, a new ``knitpack-subtree-experimental`` format has also
been added. This is interoperable with the ``dirstate-subtrees`` format.
(Robert Collins)
* New ``reconfigure`` command. (Aaron Bentley)
* New ``revert --forget-merges`` command, which removes the record of a pending
merge without affecting the working tree contents. (Martin Pool)
* New ``bzr_remote_path`` configuration variable allows finer control of
remote bzr locations than BZR_REMOTE_PATH environment variable.
(Aaron Bentley)
* New ``launchpad-login`` command to tell Bazaar your Launchpad
user ID. This can then be used by other functions of the
Launchpad plugin. (James Henstridge)
PERFORMANCE:
* Commit in quiet mode is now slightly faster as the information to
output is no longer calculated. (Ian Clatworthy)
* Commit no longer checks for new text keys during insertion when the
revision id was deterministically unique. (Robert Collins)
* Committing a change which is not a merge and does not change the number of
files in the tree is faster by utilising the data about whether files are
changed to determine if the tree is unchanged rather than recalculating
it at the end of the commit process. (Robert Collins)
* Inventory serialisation no longer double-sha's the content.
(Robert Collins)
* Knit text reconstruction now avoids making copies of the lines list for
interim texts when building a single text. The new ``apply_delta`` method
on ``KnitContent`` aids this by allowing modification of the revision id
such objects represent. (Robert Collins)
* Pack indices are now partially parsed for specific key lookup using a
bisection approach. (Robert Collins)
* Partial commits are now approximately 40% faster by walking over the
unselected current tree more efficiently. (Robert Collins)
* XML inventory serialisation takes 20% less time while being stricter about
the contents. (Robert Collins)
* Graph ``heads()`` queries have been fixed to no longer access all history
unnecessarily. (Robert Collins)
IMPROVEMENTS:
* ``bzr+https://`` smart server across https now supported.
(John Ferlito, Martin Pool, #128456)
* Mutt is now a supported mail client; set ``mail_client=mutt`` in your
bazaar.conf and ``send`` will use mutt. (Keir Mierle)
* New option ``-c``/``--change`` for ``merge`` command for cherrypicking
changes from one revision. (Alexander Belchenko, #141368)
* Show encodings, locale and list of plugins in the traceback message.
(Martin Pool, #63894)
* Experimental directory formats can now be marked with
``experimental = True`` during registration. (Ian Clatworthy)
DOCUMENTATION:
* New *Bazaar in Five Minutes* guide. (Matthew Revell)
* The hooks reference documentation is now converted to html as expected.
(Ian Clatworthy)
bzr 0.91 2007-09-26
===================
BUG FIXES
bzr 0.91rc2 2007-09-11
======================
* Replaced incorrect tarball for previous release; a debug statement was left
in bzrlib/remote.py.
bzr 0.91rc1 2007-09-11
======================
CHANGES:
* The default branch and repository format has changed to
``dirstate-tags``, so tag commands are active by default.
This format is compatible with Bazaar 0.15 and later.
This incidentally fixes bug #126141.
(Martin Pool)
* ``--quiet`` or ``-q`` is no longer a global option. If present, it
must now appear after the command name. Scripts doing things like
``bzr -q missing`` need to be rewritten as ``bzr missing -q``.
(Ian Clatworthy)
FEATURES:
* New option ``--author`` in ``bzr commit`` to specify the author of the
change, if it's different from the committer. ``bzr log`` and
``bzr annotate`` display the author instead of the committer.
(Lukáš Lalinský)
* In addition to global options and command specific options, a set of
standard options are now supported. Standard options are legal for
all commands. The initial set of standard options are:
* ``--help`` or ``-h`` - display help message
* ``--verbose`` or ``-v`` - display additional information
* ``--quiet`` or ``-q`` - only output warnings and errors.
Unlike global options, standard options can be used in aliases and
may have command-specific help. (Ian Clatworthy)
* Verbosity level processing has now been unified. If ``--verbose``
or ``-v`` is specified on the command line multiple times, the
verbosity level is made positive the first time then increased.
If ``--quiet`` or ``-q`` is specified on the command line
multiple times, the verbosity level is made negative the first
time then decreased. To get the default verbosity level of zero,
either specify none of the above , ``--no-verbose`` or ``--no-quiet``.
Note that most commands currently ignore the magnitude of the
verbosity level but do respect *quiet vs normal vs verbose* when
generating output. (Ian Clatworthy)
* ``Branch.hooks`` now supports ``pre_commit`` hook. The hook's signature
is documented in BranchHooks constructor. (Nam T. Nguyen, #102747)
BUG FIXES
IMPROVEMENTS:
* Add the option "--show-diff" to the commit command in order to display
the diff during the commit log creation. (Goffredo Baroncelli)
* ``pull`` and ``merge`` are much faster at installing bundle format 4.
(Aaron Bentley)
* ``pull -v`` no longer includes deltas, making it much faster.
(Aaron Bentley)
* ``send`` now sends the directive as an attachment by default.
(Aaron Bentley, Lukáš Lalinský, Alexander Belchenko)
* Documentation updates (Martin Albisetti)
* Help on debug flags is now included in ``help global-options``.
(Daniel Watkins, #124853)
* Parameters passed on the command line are checked to ensure they are
supported by the encoding in use. (Daniel Watkins)
* The compression used within the bzr repository has changed from zlib
level 9 to the zlib default level. This improves commit performance with
only a small increase in space used (and in some cases a reduction in
space). (Robert Collins)
* Initial commit no longer SHAs files twice and now reuses the path
rather than looking it up again, making it faster.
(Ian Clatworthy)
* New option ``-c``/``--change`` for ``diff`` and ``status`` to show
changes in one revision. (Lukáš Lalinský)
* If versioned files match a given ignore pattern, a warning is now
given. (Daniel Watkins, #48623)
* ``bzr status`` now has -S as a short name for --short and -V as a
short name for --versioned. These have been added to assist users
migrating from Subversion: ``bzr status -SV`` is now like
``svn status -q``. (Daniel Watkins, #115990)
* Added C implementation of ``PatienceSequenceMatcher``, which is about
10x faster than the Python version. This speeds up commands that
need file diffing, such as ``bzr commit`` or ``bzr diff``.
(Lukáš Lalinský)
* HACKING has been extended with a large section on core developer tasks.
(Ian Clatworthy)
* Add ``branches`` and ``standalone-trees`` as online help topics and
include them as Concepts within the User Reference.
(Paul Moore, Ian Clatworthy)
API BREAKS:
* ``Branch.append_revision`` is removed altogether; please use
``Branch.set_last_revision_info`` instead. (Martin Pool)
* CommitBuilder now advertises itself as requiring the root entry to be
supplied. This only affects foreign repository implementations which reuse
CommitBuilder directly and have changed record_entry_contents to require
that the root not be supplied. This should be precisely zero plugins
affected. (Robert Collins)
* The ``add_lines`` methods on ``VersionedFile`` implementations has changed
its return value to include the sha1 and length of the inserted text. This
allows the avoidance of double-sha1 calculations during commit.
(Robert Collins)
* ``Transport.should_cache`` has been removed. It was not called in the
previous release. (Martin Pool)
TESTING:
* Tests may now raise TestNotApplicable to indicate they shouldn't be
run in a particular scenario. (Martin Pool)
* New function multiply_tests_from_modules to give a simpler interface
to test parameterization. (Martin Pool, Robert Collins)
* ``Transport.should_cache`` has been removed. It was not called in the
previous release. (Martin Pool)
* NULL_REVISION is returned to indicate the null revision, not None.
(Aaron Bentley)
* Use UTF-8 encoded StringIO for log tests to avoid failures on
non-ASCII committer names. (Lukáš Lalinský)
bzr 0.90 2007-08-28
===================
IMPROVEMENTS:
* Documentation is now organized into multiple directories with a level
added for different languages or locales. Added the Mini Tutorial
and Quick Start Summary (en) documents from the Wiki, improving the
content and readability of the former. Formatted NEWS as Release Notes
complete with a Table of Conents, one heading per release. Moved the
Developer Guide into the main document catalog and provided a link
from the developer document catalog back to the main one.
(Ian Clatworthy, Sabin Iacob, Alexander Belchenko)
API CHANGES:
* The static convenience method ``BzrDir.create_repository``
is deprecated. Callers should instead create a ``BzrDir`` instance
and call ``create_repository`` on that. (Martin Pool)
bzr 0.90rc1 2007-08-14
======================
BUGFIXES:
* ``bzr init`` should connect to the remote location one time only. We
have been connecting several times because we forget to pass around the
Transport object. This modifies ``BzrDir.create_branch_convenience``,
so that we can give it the Transport we already have.
(John Arbash Meinel, Vincent Ladeuil, #111702)
* Get rid of sftp connection cache (get rid of the FTP one too).
(Vincent Ladeuil, #43731)
* bzr branch {local|remote} remote don't try to create a working tree
anymore.
(Vincent Ladeuil, #112173)
* All identified multiple connections for a single bzr command have been
fixed. See bzrlib/tests/commands directory.
(Vincent Ladeuil)
* ``bzr rm`` now does not insist on ``--force`` to delete files that
have been renamed but not otherwise modified. (Marius Kruger,
#111664)
* ``bzr selftest --bench`` no longer emits deprecation warnings
(Lukáš Lalinský)
* ``bzr status`` now honours FILE parameters for conflict lists
(Aaron Bentley, #127606)
* ``bzr checkout`` now honours -r when reconstituting a working tree.
It also honours -r 0. (Aaron Bentley, #127708)
* ``bzr add *`` no more fails on Windows if working tree contains
non-ascii file names. (Kuno Meyer, #127361)
* allow ``easy_install bzr`` runs without fatal errors.
(Alexander Belchenko, #125521)
* Graph._filter_candidate_lca does not raise KeyError if a candidate
is eliminated just before it would normally be examined. (Aaron Bentley)
* SMTP connection failures produce a nice message, not a traceback.
(Aaron Bentley)
IMPROVEMENTS:
* Don't show "dots" progress indicators when run non-interactively, such
as from cron. (Martin Pool)
* ``info`` now formats locations more nicely and lists "submit" and
"public" branches (Aaron Bentley)
* New ``pack`` command that will trigger database compression within
the repository (Robert Collins)
* Implement ``_KnitIndex._load_data`` in a pyrex extension. The pyrex
version is approximately 2-3x faster at parsing a ``.kndx`` file.
Which yields a measurable improvement for commands which have to
read from the repository, such as a 1s => 0.75s improvement in
``bzr diff`` when there are changes to be shown. (John Arbash Meinel)
* Merge is now faster. Depending on the scenario, it can be more than 2x
faster. (Aaron Bentley)
* Give a clearer warning, and allow ``python setup.py install`` to
succeed even if pyrex is not available.
(John Arbash Meinel)
* ``DirState._read_dirblocks`` now has an optional Pyrex
implementation. This improves the speed of any command that has to
read the entire DirState. (``diff``, ``status``, etc, improve by
about 10%).
``bisect_dirblocks`` has also been improved, which helps all
``_get_entry`` type calls (whenever we are searching for a
particular entry in the in-memory DirState).
(John Arbash Meinel)
* ``bzr pull`` and ``bzr push`` no longer do a complete walk of the
branch revision history for ui display unless -v is supplied.
(Robert Collins)
* ``bzr log -rA..B`` output shifted to the left margin if the log only
contains merge revisions. (Kent Gibson)
* The ``plugins`` command is now public with improved help.
(Ian Clatworthy)
* New bundle and merge directive formats are faster to generate, and
* Annotate merge now works when there are local changes. (Aaron Bentley)
* Commit now only shows the progress in terms of directories instead of
entries. (Ian Clatworthy)
* Fix ``KnitRepository.get_revision_graph`` to not request the graph 2
times. This makes ``get_revision_graph`` 2x faster. (John Arbash
Meinel)
* Fix ``VersionedFile.get_graph()`` to avoid using
``set.difference_update(other)``, which has bad scaling when
``other`` is large. This improves ``VF.get_graph([version_id])`` for
a 12.5k graph from 2.9s down to 200ms. (John Arbash Meinel)
* The ``--lsprof-file`` option now generates output for KCacheGrind if
the file starts with ``callgrind.out``. This matches the default file
filtering done by KCacheGrind's Open Dialog. (Ian Clatworthy)
* Fix ``bzr update`` to avoid an unnecessary
``branch.get_master_branch`` call, which avoids 1 extra connection
to the remote server. (Partial fix for #128076, John Arbash Meinel)
* Log errors from the smart server in the trace file, to make debugging
test failures (and live failures!) easier. (Andrew Bennetts)
* The HTML version of the man page has been superceded by a more
comprehensive manual called the Bazaar User Reference. This manual
is completed generated from the online help topics. As part of this
change, limited reStructuredText is now explicitly supported in help
topics and command help with 'unnatural' markup being removed prior
to display by the online help or inclusion in the man page.
(Ian Clatworthy)
* HTML documentation now use files extension ``*.html``
(Alexander Belchenko)
* The cache of ignore definitions is now cleared in WorkingTree.unlock()
so that changes to .bzrignore aren't missed. (#129694, Daniel Watkins)
* ``bzr selftest --strict`` fails if there are any missing features or
expected test failures. (Daniel Watkins, #111914)
* Link to registration survey added to README. (Ian Clatworthy)
* Windows standalone installer show link to registration survey
when installation finished. (Alexander Belchenko)
LIBRARY API BREAKS:
* Deprecated dictionary ``bzrlib.option.SHORT_OPTIONS`` removed.
Options are now required to provide a help string and it must
comply with the style guide by being one or more sentences with an
initial capital and final period. (Martin Pool)
* KnitIndex.get_parents now returns tuples. (Robert Collins)
* Ancient unused ``Repository.text_store`` attribute has been removed.
(Robert Collins)
* The ``bzrlib.pack`` interface has changed to use tuples of bytestrings
rather than just bytestrings, making it easier to represent multiple
element names. As this interface was not used by any internal facilities
since it was introduced in 0.18 no API compatibility is being preserved.
The serialised form of these packs is identical with 0.18 when a single
element tuple is in use. (Robert Collins)
TESTING:
* Remove selftest ``--clean-output``, ``--numbered-dirs`` and
``--keep-output`` options, which are obsolete now that tests
are done within directories in $TMPDIR. (Martin Pool)
* The SSH_AUTH_SOCK environment variable is now reset to avoid
interaction with any running ssh agents. (Jelmer Vernooij, #125955)
* run_bzr_subprocess handles parameters the same way as run_bzr:
either a string or a list of strings should be passed as the first
parameter. Varargs-style parameters are deprecated. (Aaron Bentley)
bzr 0.18 2007-07-17
BUGFIXES
bzr 0.18rc1 2007-07-10
BUGFIXES
IMPROVEMENTS:
* The --lsprof-file option now dumps a text rendering of the profiling
information if the filename ends in ".txt". It will also convert the
profiling information to a format suitable for KCacheGrind if the
output filename ends in ".callgrind". Fixes to the lsprofcalltree
conversion process by Jean Paul Calderone and Itamar were also merged.
See http://ddaa.net/blog/python/lsprof-calltree. (Ian Clatworthy)
* ``info`` now defaults to non-verbose mode, displaying only paths and
abbreviated format info. ``info -v`` displays all the information
formerly displayed by ``info``. (Aaron Bentley, Adeodato Simó)
* ``bzr missing`` now has better option names ``--this`` and ``--other``.
(Elliot Murphy)
* The internal ``weave-list`` command has become ``versionedfile-list``,
and now lists knits as well as weaves. (Aaron Bentley)
* Automatic merge base selection uses a faster algorithm that chooses
better bases in criss-cross merge situations (Aaron Bentley)
* Progress reporting in ``commit`` has been improved. The various logical
stages are now reported on as follows, namely:
* Collecting changes [Entry x/y] - Stage n/m
* Saving data locally - Stage n/m
* Uploading data to master branch - Stage n/m
* Updating the working tree - Stage n/m
* Running post commit hooks - Stage n/m
If there is no master branch, the 3rd stage is omitted and the total
number of stages is adjusted accordingly.
Each hook that is run after commit is listed with a name (as hooks
can be slow it is useful feedback).
(Ian Clatworthy, Robert Collins)
* Various operations that are now faster due to avoiding unnecessary
topological sorts. (Aaron Bentley)
* Make merge directives robust against broken bundles. (Aaron Bentley)
* The lsprof filename note is emitted via trace.note(), not standard
output. (Aaron Bentley)
* ``bzrlib`` now exports explicit API compatibility information to assist
library users and plugins. See the ``bzrlib.api`` module for details.
(Robert Collins)
* Remove unnecessary lock probes when acquiring a lockdir.
(Martin Pool)
* ``bzr --version`` now shows the location of the bzr log file, which
is especially useful on Windows. (Martin Pool)
* -D now supports hooks to get debug tracing of hooks (though its currently
minimal in nature). (Robert Collins)
* Long log format reports deltas on merge revisions.
(John Arbash Meinel, Kent Gibson)
* Make initial push over ftp more resilient. (John Arbash Meinel)
* Print a summary of changes for update just like pull does.
(Daniel Watkins, #113990)
* Add a -Dhpss option to trace smart protocol requests and responses.
(Andrew Bennetts)
bzr 0.17 2007-06-18
BUGFIXES
bzr 0.17rc1 2007-06-12
NOTES WHEN UPGRADING:
* The kind() and is_executable() APIs on the WorkingTree interface no
longer implicitly (read) locks and unlocks the tree. This *might*
impact some plug-ins and tools using this part of the API. If you find
an issue that may be caused by this change, please let us know,
particularly the plug-in/tool maintainer. If encountered, the API
fix is to surround kind() and is_executable() calls with lock_read()
and unlock() like so::
work_tree.lock_read()
try:
kind = work_tree.kind(...)
finally:
work_tree.unlock()
IMPROVEMENTS:
* There are two new help topics, working-trees and repositories that
attempt to explain these concepts. (James Westby, John Arbash Meinel,
Aaron Bentley)
* Added ``bzr log --limit`` to report a limited number of revisions.
(Kent Gibson, #3659)
* Revert does not try to preserve file contents that were originally
produced by reverting to a historical revision. (Aaron Bentley)
* ``bzr log --short`` now includes ``[merge]`` for revisions which
have more than one parent. This is a small improvement to help
understanding what changes have occurred
(John Arbash Meinel, #83887)
* TreeTransform avoids many renames when contructing large trees,
improving speed. 3.25x speedups have been observed for construction of
kernel-sized-trees, and checkouts are 1.28x faster. (Aaron Bentley)
* Commit on large trees is now faster. In my environment, a commit of
a small change to the Mozilla tree (55k files) has dropped from
66 seconds to 32 seconds. For a small tree of 600 files, commit of a
small change is 33% faster. (Ian Clatworthy)
* New --create-prefix option to bzr init, like for push. (Daniel Watkins,
#56322)
BUGFIXES
bzr 0.16 2007-05-07
BUGFIXES
IMPROVEMENTS:
* Move developer documentation to doc/developers/. This reduces clutter in
the root of the source tree and allows HACKING to be split into multiple
files. (Robert Collins, Alexander Belchenko)
* Clean up the ``WorkingTree4._iter_changes()`` internal loops as well as
``DirState.update_entry()``. This optimizes the core logic for ``bzr
diff`` and ``bzr status`` significantly improving the speed of
both. (John Arbash Meinel)
bzr 0.16rc2 2007-04-30
BUGFIXES
bzr 0.16rc1 2007-04-26
NOTES WHEN UPGRADING:
* ``bzr remove`` and ``bzr rm`` will now remove the working file, if
it could be recovered again.
This has been done for consistency with svn and the unix rm command.
The old ``remove`` behaviour has been retained in the new option
``bzr remove --keep``, which will just stop versioning the file,
but not delete it.
``bzr remove --force`` have been added which will always delete the
files.
``bzr remove`` is also more verbose.
(Marius Kruger, #82602)
IMPROVEMENTS:
* Merge directives can now be supplied as input to `merge` and `pull`,
like bundles can. (Aaron Bentley)
* Sending the SIGQUIT signal to bzr, which can be done on Unix by
pressing Control-Backslash, drops bzr into a debugger. Type ``'c'``
to continue. This can be disabled by setting the environment variable
``BZR_SIGQUIT_PDB=0``. (Martin Pool)
* selftest now supports --list-only to list tests instead of running
them. (Ian Clatworthy)
* selftest now supports --exclude PATTERN (or -x PATTERN) to exclude
tests with names that match that regular expression.
(Ian Clatworthy, #102679)
* selftest now supports --randomize SEED to run tests in a random order.
SEED is typically the value 'now' meaning 'use the current time'.
(Ian Clatworthy, #102686)
* New option ``--fixes`` to commit, which stores bug fixing annotations as
revision properties. Built-in support for Launchpad, Debian, Trac and
Bugzilla bug trackers. (Jonathan Lange, James Henstridge, Robert Collins)
* New API, ``bzrlib.bugtracker.tracker_registry``, for adding support for
other bug trackers to ``fixes``. (Jonathan Lange, James Henstridge,
Robert Collins)
* ``selftest`` has new short options ``-f`` and ``-1``. (Martin
Pool)
* ``bzrlib.tsort.MergeSorter`` optimizations. Change the inner loop
into using local variables instead of going through ``self._var``.
Improves the time to ``merge_sort`` a 10k revision graph by
approximately 40% (~700->400ms). (John Arbash Meinel)
* ``make docs`` now creates a man page at ``man1/bzr.1`` fixing bug 107388.
(Robert Collins)
* ``bzr help`` now provides cross references to other help topics using
the _see_also facility on command classes. Likewise the bzr_man
documentation, and the bzr.1 man page also include this information.
(Robert Collins)
* Tags are now included in logs, that use the long log formatter.
(Erik Bågfors, Alexander Belchenko)
* ``bzr help`` provides a clearer message when a help topic cannot be
found. (Robert Collins, #107656)
* ``bzr help`` now accepts optional prefixes for command help. The help
for all commands can now be found at ``bzr help commands/COMMANDNAME``
as well as ``bzr help COMMANDNAME`` (which only works for commands
where the name is not the same as a more general help topic).
(Robert Collins)
* ``bzr help PLUGINNAME`` will now return the module docstring from the
plugin PLUGINNAME. (Robert Collins, #50408)
* New help topic ``urlspec`` which lists the availables transports.
(Goffredo Baroncelli)
* doc/server.txt updated to document the default bzr:// port
and also update the blurb about the hpss' current status.
(Robert Collins, #107125).
* ``bzr serve`` now listens on interface 0.0.0.0 by default, making it
serve out to the local LAN (and anyone in the world that can reach the
machine running ``bzr serve``. (Robert Collins, #98918)
* A new smart server protocol version has been added. It prefixes requests
and responses with an explicit version identifier so that future protocol
revisions can be dealt with gracefully. (Andrew Bennetts, Robert Collins)
* The bzr protocol version 2 indicates success or failure in every response
without depending on particular commands encoding that consistently,
allowing future client refactorings to be much more robust about error
handling. (Robert Collins, Martin Pool, Andrew Bennetts)
* The smart protocol over HTTP client has been changed to always post to the
same ``.bzr/smart`` URL under the original location when it can. This allows
HTTP servers to only have to pass URLs ending in .bzr/smart to the smart
server handler, and not arbitrary ``.bzr/*/smart`` URLs. (Andrew Bennetts)
* digest authentication is now supported for proxies and HTTP by the urllib
based http implementation. Tested against Apache 2.0.55 and Squid
2.6.5. Basic and digest authentication are handled coherently for HTTP
and proxy: if the user is provided in the url (bzr command line for HTTP,
proxy environment variables for proxies), the password is prompted for
(only once). If the password is provided, it is taken into account. Once
the first authentication is successful, all further authentication
roundtrips are avoided by preventively setting the right authentication
header(s).
(Vincent Ladeuil).
BUGFIXES
bzr 0.15 2007-04-01
BUGFIXES:
* Handle incompatible repositories as a user issue when fetching.
(Aaron Bentley)
* Don't give a recommendation to upgrade when branching or
checking out a branch that contains an old-format working tree.
(Martin Pool)
bzr 0.15rc3 2007-03-26
CHANGES:
* A warning is now displayed when opening working trees in older
formats, to encourage people to upgrade to WorkingTreeFormat4.
(Martin Pool)
IMPROVEMENTS:
* HTTP redirections are now taken into account when a branch (or a
bundle) is accessed for the first time. A message is issued at each
redirection to inform the user. In the past, http redirections were
silently followed for each request which significantly degraded the
performances. The http redirections are not followed anymore by
default, instead a RedirectRequested exception is raised. For bzrlib
users needing to follow http redirections anyway,
bzrlib.transport.do_catching_redirections provide an easy transition
path. (vila)
INTERNALS:
* Added ``ReadLock.temporary_write_lock()`` to allow upgrading an OS read
lock to an OS write lock. Linux can do this without unlocking, Win32
needs to unlock in between. (John Arbash Meinel)
* New parameter ``recommend_upgrade`` to BzrDir.open_workingtree
to silence (when false) warnings about opening old formats.
(Martin Pool)
* Fix minor performance regression with bzr-0.15 on pre-dirstate
trees. (We were reading the working inventory too many times).
(John Arbash Meinel)
BUGFIXES:
* Take smtp_server from user config into account.
(vila, #92195)
* Restore Unicode filename handling for versioned and unversioned files.
(John Arbash Meinel, #92608)
* Don't fail during ``bzr commit`` if a file is marked removed, and
the containing directory is auto-removed. (John Arbash Meinel, #93681)
* ``bzr status FILENAME`` failed on Windows because of an uncommon
errno. (``ERROR_DIRECTORY == 267 != ENOTDIR``).
(Wouter van Heyst, John Arbash Meinel, #90819)
* ``bzr checkout source`` should create a local branch in the same
format as source. (John Arbash Meinel, #93854)
* ``bzr commit`` with a kind change was failing to update the
last-changed-revision for directories. The
InventoryDirectory._unchanged only looked at the parent_id and name,
ignoring the fact that the kind could have changed, too.
(John Arbash Meinel, #90111)
* ``bzr mv dir/subdir other`` was incorrectly updating files inside
the directory. So that there was a chance it would break commit,
etc. (John Arbash Meinel, #94037)
* Correctly handles mutiple permanent http redirections.
(vila, #88780)
bzr 0.15rc2 2007-03-14
NOTES WHEN UPGRADING:
* Release 0.15rc2 of bzr changes the ``bzr init-repo`` command to
default to ``--trees`` instead of ``--no-trees``.
Existing shared repositories are not affected.
IMPROVEMENTS:
* New ``merge-directive`` command to generate machine- and human-readable
merge requests. (Aaron Bentley)
* New ``submit:`` revision specifier makes it easy to diff against the
common ancestor with the submit location (Aaron Bentley)
* Added support for Putty's SSH implementation. (Dmitry Vasiliev)
* Added ``bzr status --versioned`` to report only versioned files,
not unknowns. (Kent Gibson)
* Merge now autodetects the correct line-ending style for its conflict
markers. (Aaron Bentley)
INTERNALS:
* Refactored SSH vendor registration into SSHVendorManager class.
(Dmitry Vasiliev)
BUGFIXES:
* New ``--numbered-dirs`` option to ``bzr selftest`` to use
numbered dirs for TestCaseInTempDir. This is default behavior
on Windows. Anyone can force named dirs on Windows
with ``--no-numbered-dirs``. (Alexander Belchenko)
* Fix ``RevisionSpec_revid`` to handle the Unicode strings passed in
from the command line. (Marien Zwart, #90501)
* Fix ``TreeTransform._iter_changes`` when both the source and
destination are missing. (Aaron Bentley, #88842)
* Fix commit of merges with symlinks in dirstate trees.
(Marien Zwart)
* Switch the ``bzr init-repo`` default from --no-trees to --trees.
(Wouter van Heyst, #53483)
bzr 0.15rc1 2007-03-07
SURPRISES:
* The default disk format has changed. Please run 'bzr upgrade' in your
working trees to upgrade. This new default is compatible for network
operations, but not for local operations. That is, if you have two
versions of bzr installed locally, after upgrading you can only use the
bzr 0.15 version. This new default does not enable tags or nested-trees
as they are incompatible with bzr versions before 0.15 over the network.
* For users of bzrlib: Two major changes have been made to the working tree
api in bzrlib. The first is that many methods and attributes, including
the inventory attribute, are no longer valid for use until one of
lock_read/lock_write/lock_tree_write has been called, and become invalid
again after unlock is called. This has been done to improve performance
and correctness as part of the dirstate development. (Robert Collins,
John A Meinel, Martin Pool, and others).
* For users of bzrlib: The attribute 'tree.inventory' should be considered
readonly. Previously it was possible to directly alter this attribute, or
its contents, and have the tree notice this. This has been made
unsupported - it may work in some tree formats, but in the newer dirstate
format such actions will have no effect and will be ignored, or even
cause assertions. All operations possible can still be carried out by a
combination of the tree API, and the bzrlib.transform API. (Robert
Collins, John A Meinel, Martin Pool, and others).
IMPROVEMENTS:
* Support for OS Windows 98. Also .bzr.log on any windows system
saved in My Documents folder. (Alexander Belchenko)
* ``bzr mv`` enhanced to support already moved files.
In the past the mv command would have failed if the source file doesn't
exist. In this situation ``bzr mv`` would now detect that the file has
already moved and update the repository accordingly, if the target file
does exist.
A new option ``--after`` has been added so that if two files already
exist, you could notify Bazaar that you have moved a (versioned) file
and replaced it with another. Thus in this case ``bzr move --after``
will only update the Bazaar identifier.
(Steffen Eichenberg, Marius Kruger)
* ``ls`` now works on treeless branches and remote branches.
(Aaron Bentley)
* ``bzr help global-options`` describes the global options.
(Aaron Bentley)
* ``bzr pull --overwrite`` will now correctly overwrite checkouts.
(Robert Collins)
* Files are now allowed to change kind (e.g. from file to symlink).
Supported by ``commit``, ``revert`` and ``status``
(Aaron Bentley)
* ``inventory`` and ``unknowns`` hidden in favour of ``ls``
(Aaron Bentley)
* ``bzr help checkouts`` descibes what checkouts are and some possible
uses of them. (James Westby, Aaron Bentley)
* A new ``-d`` option to push, pull and merge overrides the default
directory. (Martin Pool)
* Branch format 6: smaller, and potentially faster than format 5. Supports
"append_history_only" mode, where the log view and revnos do not change,
except by being added to. Stores policy settings in
".bzr/branch/branch.conf".
* append_only branches: Format 6 branches may be configured so that log
view and revnos are always consistent. Either create the branch using
"bzr init --append-revisions-only" or edit the config file as descriped
in docs/configuration.txt.
* rebind: Format 6 branches retain the last-used bind location, so if you
"bzr unbind", you can "bzr bind" to bind to the previously-selected
bind location.
* Builtin tags support, created and deleted by the ``tag`` command and
stored in the branch. Tags can be accessed with the revisionspec
``-rtag:``, and listed with ``bzr tags``. Tags are not versioned
at present. Tags require a network incompatible upgrade. To perform this
upgrade, run ``bzr upgrade --dirstate-tags`` in your branch and
repositories. (Martin Pool)
* The bzr:// transport now has a well-known port number, 4155, which it will
use by default. (Andrew Bennetts, Martin Pool)
* Bazaar now looks for user-installed plugins before looking for site-wide
plugins. (Jonathan Lange)
* ``bzr resolve`` now detects and marks resolved text conflicts.
(Aaron Bentley)
INTERNALS:
* Internally revision ids and file ids are now passed around as utf-8
bytestrings, rather than treating them as Unicode strings. This has
performance benefits for Knits, since we no longer need to decode the
revision id for each line of content, nor for each entry in the index.
This will also help with the future dirstate format.
(John Arbash Meinel)
* Reserved ids (any revision-id ending in a colon) are rejected by
versionedfiles, repositories, branches, and working trees
(Aaron Bentley)
* Minor performance improvement by not creating a ProgressBar for
every KnitIndex we create. (about 90ms for a bzr.dev tree)
(John Arbash Meinel)
* New easier to use Branch hooks facility. There are five initial hooks,
all documented in bzrlib.branch.BranchHooks.__init__ - 'set_rh',
'post_push', 'post_pull', 'post_commit', 'post_uncommit'. These hooks
fire after the matching operation on a branch has taken place, and were
originally added for the branchrss plugin. (Robert Collins)
* New method ``Branch.push()`` which should be used when pushing from a
branch as it makes performance and policy decisions to match the UI
level command ``push``. (Robert Collins).
* Add a new method ``Tree.revision_tree`` which allows access to cached
trees for arbitrary revisions. This allows the in development dirstate
tree format to provide access to the callers to cached copies of
inventory data which are cheaper to access than inventories from the
repository.
(Robert Collins, Martin Pool)
* New Branch.last_revision_info method, this is being done to allow
optimization of requests for both the number of revisions and the last
revision of a branch with smartservers and potentially future branch
formats. (Wouter van Heyst, Robert Collins)
* Allow 'import bzrlib.plugins.NAME' to work when the plugin NAME has not
yet been loaded by load_plugins(). This allows plugins to depend on each
other for code reuse without requiring users to perform file-renaming
gymnastics. (Robert Collins)
* New Repository method 'gather_stats' for statistic data collection.
This is expected to grow to cover a number of related uses mainly
related to bzr info. (Robert Collins)
* Log formatters are now managed with a registry.
``log.register_formatter`` continues to work, but callers accessing
the FORMATTERS dictionary directly will not.
* Allow a start message to be passed to the ``edit_commit_message``
function. This will be placed in the message offered to the user
for editing above the separator. It allows a template commit message
to be used more easily. (James Westby)
* ``GPGStrategy.sign()`` will now raise ``BzrBadParameterUnicode`` if
you pass a Unicode string rather than an 8-bit string. Callers need
to be updated to encode first. (John Arbash Meinel)
* Branch.push, pull, merge now return Result objects with information
about what happened, rather than a scattering of various methods. These
are also passed to the post hooks. (Martin Pool)
* File formats and architecture is in place for managing a forest of trees
in bzr, and splitting up existing trees into smaller subtrees, and
finally joining trees to make a larger tree. This is the first iteration
of this support, and the user-facing aspects still require substantial
work. If you wish to experiment with it, use ``bzr upgrade
--dirstate-with-subtree`` in your working trees and repositories.
You can use the hidden commands ``split`` and ``join`` and to create
and manipulate nested trees, but please consider using the nested-trees
branch, which contains substantial UI improvements, instead.
http://code.aaronbentley.com/bzr/bzrrepo/nested-trees/
(Aaron Bentley, Martin Pool, Robert Collins).
BUGFIXES:
* ``bzr annotate`` now uses dotted revnos from the viewpoint of the
branch, rather than the last changed revision of the file.
(John Arbash Meinel, #82158)
* Lock operations no longer hang if they encounter a permission problem.
(Aaron Bentley)
* ``bzr push`` can resume a push that was canceled before it finished.
Also, it can push even if the target directory exists if you supply
the ``--use-existing-dir`` flag.
(John Arbash Meinel, #30576, #45504)
* Fix http proxy authentication when user and an optional
password appears in the ``*_proxy`` vars. (Vincent Ladeuil,
#83954).
* ``bzr log branch/file`` works for local treeless branches
(Aaron Bentley, #84247)
* Fix problem with UNC paths on Windows 98. (Alexander Belchenko, #84728)
* Searching location of CA bundle for PyCurl in env variable (CURL_CA_BUNDLE),
and on win32 along the PATH. (Alexander Belchenko, #82086)
* ``bzr init`` works with unicode argument LOCATION.
(Alexander Belchenko, #85599)
* Raise DependencyNotPresent if pycurl do not support https. (Vincent
Ladeuil, #85305)
* Invalid proxy env variables should not cause a traceback.
(Vincent Ladeuil, #87765)
* Ignore patterns normalised to use '/' path separator.
(Kent Gibson, #86451)
* bzr rocks. It sure does! Fix case. (Vincent Ladeuil, #78026)
* Fix bzrtools shelve command for removed lines beginning with "--"
(Johan Dahlberg, #75577)
TESTING:
* New ``--first`` option to ``bzr selftest`` to run specified tests
before the rest of the suite. (Martin Pool)
bzr 0.14 2007-01-23
IMPROVEMENTS:
* ``bzr help global-options`` describes the global options. (Aaron Bentley)
BUG FIXES:
* Skip documentation generation tests if the tools to do so are not
available. Fixes running selftest for installled copies of bzr.
(John Arbash Meinel, #80330)
* Fix the code that discovers whether bzr is being run from it's
working tree to handle the case when it isn't but the directory
it is in is below a repository. (James Westby, #77306)
bzr 0.14rc1 2007-01-16
IMPROVEMENTS:
* New connection: ``bzr+http://`` which supports tunnelling the smart
protocol over an HTTP connection. If writing is enabled on the bzr
server, then you can write over the http connection.
(Andrew Bennetts, John Arbash Meinel)
* Aliases now support quotation marks, so they can contain whitespace
(Marius Kruger)
* PyCurlTransport now use a single curl object. By specifying explicitly
the 'Range' header, we avoid the need to use two different curl objects
(and two connections to the same server). (Vincent Ladeuil)
* ``bzr commit`` does not prompt for a message until it is very likely to
succeed. (Aaron Bentley)
* ``bzr conflicts`` now takes --text to list pathnames of text conflicts
(Aaron Bentley)
* Fix ``iter_lines_added_or_present_in_versions`` to use a set instead
of a list while checking if a revision id was requested. Takes 10s
off of the ``fileids_affected_by_revision_ids`` time, which is 10s
of the ``bzr branch`` time. Also improve ``fileids_...`` time by
filtering lines with a regex rather than multiple ``str.find()``
calls. (saves another 300ms) (John Arbash Meinel)
* Policy can be set for each configuration key. This allows keys to be
inherited properly across configuration entries. For example, this
should enable you to do::
[/home/user/project]
push_location = sftp://host/srv/project/
push_location:policy = appendpath
And then a branch like ``/home/user/project/mybranch`` should get an
automatic push location of ``sftp://host/srv/project/mybranch``.
(James Henstridge)
* Added ``bzr status --short`` to make status report svn style flags
for each file. For example::
$ bzr status --short
A foo
A bar
D baz
? wooley
* 'bzr selftest --clean-output' allows easily clean temporary tests
directories without running tests. (Alexander Belchenko)
* ``bzr help hidden-commands`` lists all hidden commands. (Aaron Bentley)
* ``bzr merge`` now has an option ``--pull`` to fall back to pull if
local is fully merged into remote. (Jan Hudec)
* ``bzr help formats`` describes available directory formats. (Aaron Bentley)
INTERNALS:
* A few tweaks directly to ``fileids_affected_by_revision_ids`` to
help speed up processing, as well allowing to extract unannotated
lines. Between the two ``fileids_affected_by_revision_ids`` is
improved by approx 10%. (John Arbash Meinel)
* Change Revision serialization to only write out millisecond
resolution. Rather than expecting floating point serialization to
preserve more resolution than we need. (Henri Weichers, Martin Pool)
* Test suite ends cleanly on Windows. (Vincent Ladeuil)
* When 'encoding_type' attribute of class Command is equal to 'exact',
force sys.stdout to be a binary stream on Windows, and therefore
keep exact line-endings (without LF -> CRLF conversion).
(Alexander Belchenko)
* Single-letter short options are no longer globally declared. (Martin
Pool)
* Before using detected user/terminal encoding bzr should check
that Python has corresponding codec. (Alexander Belchenko)
* Formats for end-user selection are provided via a FormatRegistry (Aaron Bentley)
BUG FIXES:
* ``bzr missing --verbose`` was showing adds/removals in the wrong
direction. (John Arbash Meinel)
* ``bzr annotate`` now defaults to showing dotted revnos for merged
revisions. It cuts them off at a depth of 12 characters, but you can
supply ``--long`` to see the full number. You can also use
``--show-ids`` to display the original revision ids, rather than
revision numbers and committer names. (John Arbash Meinel, #75637)
* bzr now supports Win32 UNC path (e.g. \\HOST\path).
(Alexander Belchenko, #57869)
* Win32-specific: output of cat, bundle and diff commands don't mangle
line-endings (Alexander Belchenko, #55276)
* Replace broken fnmatch based ignore pattern matching with custom pattern
matcher.
(Kent Gibson, Jan Hudec #57637)
* pycurl and urllib can detect short reads at different places. Update
the test suite to test more cases. Also detect http error code 416
which was raised for that specific bug. Also enhance the urllib
robustness by detecting invalid ranges (and pycurl's one by detecting
short reads during the initial GET). (Vincent Ladeuil, #73948)
* The urllib connection sharing interacts badly with urllib2
proxy setting (the connections didn't go thru the proxy
anymore). Defining a proper ProxyHandler solves the
problem. (Vincent Ladeuil, #74759)
* Use urlutils to generate relative URLs, not osutils
(Aaron Bentley, #76229)
* ``bzr status`` in a readonly directory should work without giving
lots of errors. (John Arbash Meinel, #76299)
* Mention the revisionspec topic for the revision option help.
(Wouter van Heyst, #31663)
* Allow plugins import from zip archives.
(Alexander Belchenko, #68124)
bzr 0.13 2006-12-05
No changes from 0.13rc1
bzr 0.13rc1 2006-11-27
IMPROVEMENTS:
* New command ``bzr remove-tree`` allows the removal of the working
tree from a branch.
(Daniel Silverstone)
* urllib uses shared keep-alive connections, so http
operations are substantially faster.
(Vincent Ladeuil, #53654)
* ``bzr export`` allows an optional branch parameter, to export a bzr
tree from some other url. For example:
``bzr export bzr.tar.gz http://bazaar-vcs.org/bzr/bzr.dev``
(Daniel Silverstone)
* Added ``bzr help topics`` to the bzr help system. This gives a
location for general information, outside of a specific command.
This includes updates for ``bzr help revisionspec`` the first topic
included. (Goffredo Baroncelli, John Arbash Meinel, #42714)
* WSGI-compatible HTTP smart server. See ``doc/http_smart_server.txt``.
(Andrew Bennetts)
* Knit files will now cache full texts only when the size of the
deltas is as large as the size of the fulltext. (Or after 200
deltas, whichever comes first). This has the most benefit on large
files with small changes, such as the inventory for a large project.
(eg For a project with 2500 files, and 7500 revisions, it changes
the size of inventory.knit from 11MB to 5.4MB) (John Arbash Meinel)
BUG FIXES:
* ``bzrlib/bzrdir.py`` was directly referencing ``bzrlib.workingtree``,
without importing it. This prevented ``bzr upgrade`` from working
unless a plugin already imported ``bzrlib.workingtree``
(John Arbash Meinel, #70716)
* Suppress the traceback on invalid URLs (Vincent Ladeuil, #70803).
* Give nicer error message when an http server returns a 403
error code. (Vincent Ladeuil, #57644).
* When a multi-range http GET request fails, try a single
range one. If it fails too, forget about ranges. Remember that until
the death of the transport and propagates that to the clones.
(Vincent Ladeuil, #62276, #62029).
* Handles user/passwords supplied in url from command
line (for the urllib implementation). Don't request already
known passwords (Vincent Ladeuil, #42383, #44647, #48527)
* _KnitIndex.add_versions() dictionary compresses revision ids as they
are added. This fixes bug where fetching remote revisions records
them as full references rather than integers. (John Arbash Meinel,
#64789)
* ``bzr ignore`` strips trailing slashes in patterns.
Also ``bzr ignore`` rejects absolute paths. (Kent Gibson, #4559)
* ``bzr ignore`` takes multiple arguments. (Cheuksan Edward Wang, #29488)
* mv correctly handles paths that traverse symlinks.
(Aaron Bentley, #66964)
* Give nicer looking error messages when failing to connect over ssh.
(John Arbash Meinel, #49172)
* Pushing to a remote branch does not currently update the remote working
tree. After a remote push, ``bzr status`` and ``bzr diff`` on the remote
machine now show that the working tree is out of date.
(Cheuksan Edward Wang #48136)
* Use patiencediff instead of difflib for determining deltas to insert
into knits. This avoids the O(N^3) behavior of difflib. Patience
diff should be O(N^2). (Cheuksan Edward Wang, #65714)
* Running ``bzr log`` on nonexistent file gives an error instead of the
entire log history. (Cheuksan Edward Wang #50793)
* ``bzr cat`` can look up contents of removed or renamed files. If the
pathname is ambiguous, i.e. the files in the old and new trees have
different id's, the default is the file in the new tree. The user can
use "--name-from-revision" to select the file in the old tree.
(Cheuksan Edward Wang, #30190)
bzr 0.12 2006-10-30
IMPROVEMENTS:
* ``bzr log`` now shows dotted-decimal revision numbers for all revisions,
rather than just showing a decimal revision number for revisions on the
mainline. These revision numbers are not yet accepted as input into bzr
commands such as log, diff etc. (Robert Collins)
* revisions can now be specified using dotted-decimal revision numbers.
For instance, ``bzr diff -r 1.2.1..1.2.3. (Robert Collins)
* ``bzr help commands`` output is now shorter (Aaron Bentley)
* New connection: ``bzr+http://`` which supports tunnelling the smart
protocol over an HTTP connection. If writing is enabled on the bzr
server, then you can write over the http connection.
(Andrew Bennetts)
* ``bzr`` now uses lazy importing to reduce the startup time. This has
a moderate effect on lots of actions, especially ones that have
little to do. For example ``bzr rocks`` time is down to 116ms from
283ms. (John Arbash Meinel)
* New Registry class to provide name-to-object registry-like support,
for example for schemes where plugins can register new classes to
do certain tasks (e.g. log formatters). Also provides lazy registration
to allow modules to be loaded on request. (John Arbash Meinel, Adeodato
Simó)
API INCOMPATABILITY:
* LogFormatter subclasses show now expect the 'revno' parameter to
show() to be a string rather than an int. (Robert Collins)
As well as changes to the internals, tests, and bug fixes.
bzr 0.11 2006-10-02
* Smart server transport test failures on windows fixed. (Lukáš Lalinský).
bzr 0.11rc2 2006-09-27
BUG FIXES:
* Test suite hangs on windows fixed. (Andrew Bennets, Alexander Belchenko).
* Commit performance regression fixed. (Aaron Bentley, Robert Collins, John
Arbash Meinel).
bzr 0.11rc1 2006-09-25
IMPROVEMENTS:
* Knit files now wait to create their contents until the first data is
added. The old code used to create an empty .knit and a .kndx with just
the header. However, this caused a lot of extra round trips over sftp.
This can change the time for ``bzr push`` to create a new remote branch
from 160s down to 100s. This also affects ``bzr commit`` performance when
adding new files, ``bzr commit`` on a new kernel-like tree drops from 50s
down to 40s (John Arbash Meinel, #44692)
* When an entire subtree has been deleted, commit will now report that
just the top of the subtree has been deleted, rather than reporting
all the individual items. (Robert Collins)
* Commit performs one less XML parse. (Robert Collins)
* ``bzr checkout`` now operates on readonly branches as well
as readwrite branches. This fixes bug #39542. (Robert Collins)
* ``bzr bind`` no longer synchronises history with the master branch.
Binding should be followed by an update or push to synchronise the
two branches. This is closely related to the fix for bug #39542.
(Robert Collins)
* ``bzrlib.lazy_import.lazy_import`` function to create on-demand
objects. This allows all imports to stay at the global scope, but
modules will not actually be imported if they are not used.
(John Arbash Meinel)
* Support bzr:// and bzr+ssh:// urls to work with the new RPC-based
transport which will be used with the upcoming high-performance smart
server. The new command ``bzr serve`` will invoke bzr in server mode,
which processes these requests. (Andrew Bennetts, Robert Collins, Martin
Pool)
* New command ``bzr version-info`` which can be used to get a summary
of the current state of the tree. This is especially useful as part
of a build commands. See ``doc/version_info.txt`` for more information
(John Arbash Meinel)
bzr 0.10 2006-08-29
IMPROVEMENTS:
* 'merge' now takes --uncommitted, to apply uncommitted changes from a
tree. (Aaron Bentley)
* 'bzr add --file-ids-from' can be used to specify another path to use
for creating file ids, rather than generating all new ones. Internally,
the 'action' passed to smart_add_tree() can return file_ids that
will be used, rather than having bzrlib generate new ones.
(John Arbash Meinel, #55781)
* ``bzr selftest --benchmark`` now allows a ``--cache-dir`` parameter.
This will cache some of the intermediate trees, and decrease the
setup time for benchmark tests. (John Arbash Meinel)
* Inverse forms are provided for all boolean options. For example,
--strict has --no-strict, --no-recurse has --recurse (Aaron Bentley)
* Serialize out Inventories directly, rather than using ElementTree.
Writing out a kernel sized inventory drops from 2s down to ~350ms.
(Robert Collins, John Arbash Meinel)
(BUG FIXES, INTERNALS, and TESTING updates removed from commit message)
bzr 0.9.0 2006-08-11
SURPRISES:
* The hard-coded built-in ignore rules have been removed. There are
now two rulesets which are enforced. A user global one in
~/.bazaar/ignore which will apply to every tree, and the tree
specific one '.bzrignore'.
~/.bazaar/ignore will be created if it does not exist, but with
a more conservative list than the old default.
This fixes bugs with default rules being enforced no matter what.
The old list of ignore rules from bzr is available by
running 'bzr ignore --old-default-rules'.
(Robert Collins, Martin Pool, John Arbash Meinel)
* 'branches.conf' has been changed to 'locations.conf', since it can apply
to more locations than just branch locations.
(Aaron Bentley)
IMPROVEMENTS:
* The revision specifier "revno:" is extended to accept the syntax
revno:N:branch. For example,
revno:42:http://bazaar-vcs.org/bzr/bzr.dev/ means revision 42 in
bzr.dev. (Matthieu Moy)
* Tests updates to ensure proper URL handling, UNICODE support, and
proper printing when the user's terminal encoding cannot display
the path of a file that has been versioned.
``bzr branch`` can take a target URL rather than only a local directory.
Branch.get_parent()/set_parent() now save a relative path if possible,
and normalize the parent based on root, allowing access across
different transports. (John Arbash Meinel, Wouter van Heyst, Martin Pool)
(Malone #48906, #42699, #40675, #5281, #3980, #36363, #43689,
#42517, #42514)
* On Unix, detect terminal width using an ioctl not just $COLUMNS.
Use terminal width for single-line logs from ``bzr log --line`` and
pending-merge display. (Robert Widhopf-Fenk, Gustavo Niemeyer)
(Malone #3507)
* On Windows, detect terminal width using GetConsoleScreenBufferInfo.
(Alexander Belchenko)
* Speedup improvement for 'date:'-revision search. (Guillaume Pinot).
* Show the correct number of revisions pushed when pushing a new branch.
(Robert Collins).
* 'bzr selftest' now shows a progress bar with the number of tests, and
progress made. 'make check' shows tests in -v mode, to be more useful
for the PQM status window. (Robert Collins).
When using a progress bar, failed tests are printed out, rather than
being overwritten by the progress bar until the suite finishes.
(John Arbash Meinel)
* 'bzr selftest --benchmark' will run a new benchmarking selftest.
'bzr selftest --benchmark --lsprof-timed' will use lsprofile to generate
profile data for the individual profiled calls, allowing for fine
grained analysis of performance.
(Robert Collins, Martin Pool).
* 'bzr commit' shows a progress bar. This is useful for commits over sftp
where commit can take an appreciable time. (Robert Collins)
* 'bzr add' is now less verbose in telling you what ignore globs were
matched by files being ignored. Instead it just tells you how many
were ignored (because you might reasonably be expecting none to be
ignored). 'bzr add -v' is unchanged and will report every ignored
file. (Robert Collins).
* ftp now has a test server if medusa is installed. As part of testing,
ftp support has been improved, including support for supplying a
non-standard port. (John Arbash Meinel).
* 'bzr log --line' shows the revision number, and uses only the
first line of the log message (#5162, Alexander Belchenko;
Matthieu Moy)
* 'bzr status' has had the --all option removed. The 'bzr ls' command
should be used to retrieve all versioned files. (Robert Collins)
* 'bzr bundle OTHER/BRANCH' will create a bundle which can be sent
over email, and applied on the other end, while maintaining ancestry.
This bundle can be applied with either 'bzr merge' or 'bzr pull',
the same way you would apply another branch.
(John Arbash Meinel, Aaron Bentley)
* 'bzr whoami' can now be used to set your identity from the command line,
for a branch or globally. (Robey Pointer)
* 'bzr checkout' now aliased to 'bzr co', and 'bzr annotate' to 'bzr ann'.
(Michael Ellerman)
* 'bzr revert DIRECTORY' now reverts the contents of the directory as well.
(Aaron Bentley)
* 'bzr get sftp://foo' gives a better error when paramiko is not present.
Also updates things like 'http+pycurl://' if pycurl is not present.
(John Arbash Meinel) (Malone #47821, #52204)
* New env variable BZR_PROGRESS_BAR, sets the default progress bar type.
Can be set to 'none' or 'dummy' to disable the progress bar, 'dots' or
'tty' to create the respective type. (John Arbash Meinel, #42197, #51107)
* Improve the help text for 'bzr diff' to explain what various options do.
(John Arbash Meinel, #6391)
* 'bzr uncommit -r 10' now uncommits revisions 11.. rather than uncommitting
revision 10. This makes -r10 more in line with what other commands do.
'bzr uncommit' also now saves the pending merges of the revisions that
were removed. So it is safe to uncommit after a merge, fix something,
and commit again. (John Arbash Meinel, #32526, #31426)
* 'bzr init' now also works on remote locations.
(Wouter van Heyst, #48904)
* HTTP support has been updated. When using pycurl we now support
connection keep-alive, which reduces dns requests and round trips.
And for both urllib and pycurl we support multi-range requests,
which decreases the number of round-trips. Performance results for
``bzr branch http://bazaar-vcs.org/bzr/bzr.dev/`` indicate
http branching is now 2-3x faster, and ``bzr pull`` in an existing
branch is as much as 4x faster.
(Michael Ellerman, Johan Rydberg, John Arbash Meinel, #46768)
* Performance improvements for sftp. Branching and pulling are now up to
2x faster. Utilize paramiko.readv() support for async requests if it
is available (paramiko > 1.6) (John Arbash Meinel)
BUG FIXES:
* Fix shadowed definition of TestLocationConfig that caused some
tests not to run. (#32587, Erik Bågfors, Michael Ellerman,
Martin Pool)
* Fix unnecessary requirement of sign-my-commits that it be run from
a working directory. (Martin Pool, Robert Collins)
* 'bzr push location' will only remember the push location if it succeeds
in connecting to the remote location. (#49742, John Arbash Meinel)
* 'bzr revert' no longer toggles the executable bit on win32
(#45010, John Arbash Meinel)
* Handle broken pipe under win32 correctly. (John Arbash Meinel)
* sftp tests now work correctly on win32 if you have a newer paramiko
(John Arbash Meinel)
* Cleanup win32 test suite, and general cleanup of places where
file handles were being held open. (John Arbash Meinel)
* When specifying filenames for 'diff -r x..y', the name of the file in the
working directory can be used, even if its name is different in both x
and y.
* File-ids containing single- or double-quotes are handled correctly by
push. (#52227, Aaron Bentley)
* Normalize unicode filenames to ensure cross-platform consistency.
(John Arbash Meinel, #43689)
* The argument parser can now handle '-' as an argument. Currently
no code interprets it specially (it is mostly handled as a file named
'-'). But plugins, and future operations can use it.
(John Arbash meinel, #50984)
* Bundles can properly read binary files with a plain '\r' in them.
(John Arbash Meinel, #51927)
* Tuning iter_entries() to be more efficient (John Arbash Meinel, #5444)
* Lots of win32 fixes (the test suite passes again).
(John Arbash Meinel, #50155)
* Handle openbsd returning None for sys.getfilesystemencoding() (#41183)
* Support ftp APPE (append) to allow Knits to be used over ftp (#42592)
* Removals are only committed if they match the filespec (or if there is
no filespec). (#46635, Aaron Bentley)
* smart-add recurses through all supplied directories
(John Arbash Meinel, #52578)
* Make the bundle reader extra lines before and after the bundle text.
This allows you to parse an email with the bundle inline.
(John Arbash Meinel, #49182)
* Change the file id generator to squash a little bit more. Helps when
working with long filenames on windows. (Also helps for unicode filenames
not generating hidden files). (John Arbash Meinel, #43801)
* Restore terminal mode on C-c while reading sftp password. (#48923,
Nicholas Allen, Martin Pool)
* Timestamps are rounded to 1ms, and revision entries can be recreated
exactly. (John Arbash Meinel, Jamie Wilkinson, #40693)
* Branch.base has changed to a URL, but ~/.bazaar/locations.conf should
use local paths, since it is user visible (John Arbash Meinel, #53653)
* ``bzr status foo`` when foo was unversioned used to cause a full delta
to be generated (John Arbash Meinel, #53638)
* When reading revision properties, an empty value should be considered
the empty string, not None (John Arbash Meinel, #47782)
* ``bzr diff --diff-options`` can now handle binary files being changed.
Also, the output is consistent when --diff-options is not supplied.
(John Arbash Meinel, #54651, #52930)
* Use the right suffixes for loading plugins (John Arbash Meinel, #51810)
* Fix Branch.get_parent() to handle the case when the parent is not
accessible (John Arbash Meinel, #52976)

* Add info on standalone branches without a working tree.
(#44155, Olaf Conradi)
* Fix bug in knits when raising InvalidRevisionId. (#44284, Olaf Conradi)

(Martin Pool, Bjorn Tillenius, Robert Collins)
TESTING:

uses bzrlib api now. (Olaf Conradi)
bzr 0.8 2006-05-08
NOTES WHEN UPGRADING:
Release 0.8 of bzr introduces a new format for history storage, called
'knit', as an evolution of to the 'weave' format used in 0.7. Local
and remote operations are faster using knits than weaves. Several
operations including 'init', 'init-repo', and 'upgrade' take a
--format option that controls this. Branching from an existing branch
will keep the same format.
It is possible to merge, pull and push between branches of different
formats but this is slower than moving data between homogenous
branches. It is therefore recommended (but not required) that you
upgrade all branches for a project at the same time. Information on
formats is shown by 'bzr info'.
bzr 0.8 now allows creation of 'repositories', which hold the history
of files and revisions for several branches. Previously bzr kept all
the history for a branch within the .bzr directory at the root of the
branch, and this is still the default. To create a repository, use
the new 'bzr init-repo' command. Branches exist as directories under
the repository and contain just a small amount of information
indicating the current revision of the branch.
bzr 0.8 also supports 'checkouts', which are similar to in cvs and
subversion. Checkouts are associated with a branch (optionally in a
repository), which contains all the historical information. The
result is that a checkout can be deleted without losing any
already-committed revisions. A new 'update' command is also available.
Repositories and checkouts are not supported with the 0.7 storage
format. To use them you must upgrad to either knits, or to the
'metaweave' format, which uses weaves but changes the .bzr directory
arrangement.
IMPROVEMENTS:
* Sftp paths can now be relative, or local, according to the lftp
convention. Paths now take the form:
sftp://user:pass@host:port/~/relative/path
or
sftp://user:pass@host:port/absolute/path
* The FTP transport now tries to reconnect after a temporary
failure. ftp put is made atomic. (Matthieu Moy)
* The FTP transport now maintains a pool of connections, and
reuses them to avoid multiple connections to the same host (like
sftp did). (Daniel Silverstone)
* The bzr_man.py file has been removed. To create the man page now,
use ./generate_docs.py man. The new program can also create other files.
Run "python generate_docs.py --help" for usage information. (Hans
Ulrich Niedermann & James Blackwell).
* Man Page now gives full help (James Blackwell). Help also updated to
reflect user config now being stored in .bazaar (Hans Ulrich
Niedermann)
* It's now possible to set aliases in bazaar.conf (Erik Bågfors)
* Pull now accepts a --revision argument (Erik Bågfors)
* 'bzr re-sign' now allows multiple revisions to be supplied on the command
line. You can now use the following command to sign all of your old commits.
find .bzr/revision-store// -name my@email-* \
| sed 's/.*\/\/..\///' \
| xargs bzr re-sign
* Upgrade can now upgrade over the network. (Robert Collins)
* Two new commands 'bzr checkout' and 'bzr update' allow for CVS/SVN-alike
behaviour. By default they will cache history in the checkout, but
with --lightweight almost all data is kept in the master branch.
(Robert Collins)
* 'revert' unversions newly-versioned files, instead of deleting them.
* 'merge' is more robust. Conflict messages have changed.
* 'merge' and 'revert' no longer clobber existing files that end in '~' or
'.moved'.
* Default log format can be set in configuration and plugins can register
their own formatters. (Erik Bågfors)
* New 'reconcile' command will check branch consistency and repair indexes
that can become out of sync in pre 0.8 formats. (Robert Collins,
Daniel Silverstone)
* New 'bzr init --format' and 'bzr upgrade --format' option to control
what storage format is created or produced. (Robert Collins,
Martin Pool)
* Add parent location to 'bzr info', if there is one. (Olaf Conradi)
* New developer commands 'weave-list' and 'weave-join'. (Martin Pool)
* New 'init-repository' command, plus support for repositories in 'init'
and 'branch' (Aaron Bentley, Erik Bågfors, Robert Collins)
* Improve output of 'info' command. Show all relevant locations related to
working tree, branch and repository. Use kibibytes for binary quantities.
Fix off-by-one error in missing revisions of working tree. Make 'info'
work on branches, repositories and remote locations. Show locations
relative to the shared repository, if applicable. Show locking status
of locations. (Olaf Conradi)
* Diff and merge now safely handle binary files. (Aaron Bentley)
* 'pull' and 'push' now normalise the revision history, so that any two
branches with the same tip revision will have the same output from 'log'.
(Robert Collins)
* 'merge' accepts --remember option to store parent location, like 'push'
and 'pull'. (Olaf Conradi)
* bzr status and diff when files given as arguments do not exist
in the relevant trees. (Martin Pool, #3619)
* Add '.hg' to the default ignore list. (Martin Pool)
* 'knit' is now the default disk format. This improves disk performance and
utilization, increases incremental pull performance, robustness with SFTP
and allows checkouts over SFTP to perform acceptably.
The initial Knit code was contributed by Johan Rydberg based on a
specification by Martin Pool.
(Robert Collins, Aaron Bentley, John Rydberg, Martin Pool).
* New tool to generate all-in-one html version of the manual. (Alexander
Belchenko)
* Hitting CTRL-C while doing an SFTP push will no longer cause stale locks
to be left in the SFTP repository. (Robert Collins, Martin Pool).
* New option 'diff --prefix' to control how files are named in diff
output, with shortcuts '-p0' and '-p1' corresponding to the options for
GNU patch. (Alexander Belchenko, Goffredo Baroncelli, Martin Pool)
* Add --revision option to 'annotate' command. (Olaf Conradi)
* If bzr shows an unexpected revision-history after pulling (perhaps due
to a reweave) it can now be corrected by 'bzr reconcile'.
(Robert Collins)
CHANGES:
* Commit is now verbose by default, and shows changed filenames and the
new revision number. (Robert Collins, Martin Pool)
* Unify 'mv', 'move', 'rename'. (#5379, Matthew Fuller)
* 'bzr -h' shows help. (#35940, Martin Pool, Ian Bicking)
* Make 'pull' and 'push' remember location on failure using --remember.
(Olaf Conradi)
* For compatibility, make old format for using weaves inside metadir
available as 'metaweave' format. Rename format 'metadir' to 'default'.
Clean up help for option --format in commands 'init', 'init-repo' and
'upgrade'. (Olaf Conradi)
TESTING:
* SFTP tests now shortcut the SSH negotiation, reducing test overhead
for testing SFTP protocol support. (Robey Pointer)
* Branch formats are now tested once per implementation (see bzrlib.
tests.branch_implementations. This is analagous to the transport
interface tests, and has been followed up with working tree,
repository and BzrDir tests. (Robert Collins)
* New test base class TestCaseWithTransport provides a transport aware
test environment, useful for testing any transport-interface using
code. The test suite option --transport controls the transport used
by this class (when its not being used as part of implementation
contract testing). (Robert Collins)
* Close logging handler on disabling the test log. This will remove the
handler from the internal list inside python's logging module,
preventing shutdown from closing it twice. (Olaf Conradi)
* Move test case for uncommit to blackbox tests. (Olaf Conradi)
* run_bzr and run_bzr_captured now accept a 'stdin="foo"' parameter which
will provide String("foo") to the command as its stdin.
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
bzr 0.7 2006-01-23
CHANGES:
* .bzrignore is excluded from exports, on the grounds that it's a bzr
internal-use file and may not be wanted. (Jamie Wilkinson)
* The "bzr directories" command were removed in favor of the new
--kind option to the "bzr inventory" command. To list all
versioned directories, now use "bzr inventory --kind directory".
(Johan Rydberg)
* Under Windows configuration directory is now %APPDATA%\bazaar\2.0
by default. (John Arbash Meinel)
* The parent of Bzr configuration directory can be set by BZR_HOME
environment variable. Now the path for it is searched in BZR_HOME, then
in HOME. Under Windows the order is: BZR_HOME, APPDATA (usually
points to C:\Documents and Settings\User Name\Application Data), HOME.
(John Arbash Meinel)
* Plugins with the same name in different directories in the bzr plugin
path are no longer loaded: only the first successfully loaded one is
used. (Robert Collins)
* Use systems' external ssh command to open connections if possible.
This gives better integration with user settings such as ProxyCommand.
(James Henstridge)
* Sftp paths can now be relative, or local, according to the IETF
draft spec. Paths now take the form:
sftp://user:pass@host:port/relative/path
or
sftp://user:pass@host:port/%2Fabsolute/path
or
sftp://user:pass@host:port//absolute/path
* Permissions on files underneath .bzr/ are inherited from the .bzr
directory. So for a shared repository, simply doing 'chmod -R g+w .bzr/'
will mean that future file will be created with group write permissions.
* configure.in and config.guess are no longer in the builtin default
ignore list.
* '.sw[nop]' pattern ignored, to ignore vim swap files for nameless
files. (John Arbash Meinel, Martin Pool)
IMPROVEMENTS:
* "bzr INIT dir" now initializes the specified directory, and creates
it if it does not exist. (John Arbash Meinel)
* New remerge command (Aaron Bentley)
* Better zsh completion script. (Steve Borho)
* 'bzr diff' now returns 1 when there are changes in the working
tree. (Robert Collins)
* 'bzr push' now exists and can push changes to a remote location.
This uses the transport infrastructure, and can store the remote
location in the ~/.bazaar/branches.conf configuration file.
(Robert Collins)
* Test directories are only kept if the test fails and the user requests
that they be kept.
* Tweaks to short log printing
* Added branch nicks, new nick command, printing them in log output.
(Aaron Bentley)
* If $BZR_PDB is set, pop into the debugger when an uncaught exception
occurs. (Martin Pool)
* Accept 'bzr resolved' (an alias for 'bzr resolve'), as this is
the same as Subversion. (Martin Pool)
* New ftp transport support (on ftplib), for ftp:// and aftp://
URLs. (Daniel Silverstone)
* Commit editor temporary files now start with 'bzr_log.', to allow
text editors to match the file name and set up appropriate modes or
settings. (Magnus Therning)
* Improved performance when integrating changes from a remote weave.
(Goffredo Baroncelli)
* Sftp will attempt to cache the connection, so it is more likely that
a connection will be reused, rather than requiring multiple password
requests.
* bzr revno now takes an optional argument indicating the branch whose
revno should be printed. (Michael Ellerman)
* bzr cat defaults to printing the last version of the file.
(#3632, Matthieu Moy)
* New global option 'bzr --lsprof COMMAND' runs bzr under the lsprof
profiler. (Denys Duchier)
* Faster commits by reading only the headers of affected weave files.
(Denys Duchier)
* 'bzr add' now takes a --dry-run parameter which shows you what would be
added, but doesn't actually add anything. (Michael Ellerman)
* bzr add now lists how many files were ignored per glob. add --verbose
lists the specific files. (Aaron Bentley)
* Reduced CPU usage for merge/fetch. (Goffredo Baroncelli)
* Faster diff and status commands. (Denys Duchier)
BUG FIXES:
* SFTP can walk up to the root path without index errors. (Robert Collins)
* Fix bugs in running bzr with 'python -O'. (Martin Pool)
* Error when run with -OO
* Fix bug in reporting http errors that don't have an http error code.
(Martin Pool)
* Handle more cases of pipe errors in display commands
* Change status to 3 for all errors
* Files that are added and unlinked before committing are completely
ignored by diff and status
* Stores with some compressed texts and some uncompressed texts are now
able to be used. (John A Meinel)
* Fix for bzr pull failing sometimes under windows
* Fix for sftp transport under windows when using interactive auth
* Show files which are both renamed and modified as such in 'bzr
status' output. (#4503, Daniel Silverstone)
* Make annotate cope better with revisions committed without a valid
email address. (Marien Zwart)
* Fix representation of tab characters in commit messages. (Harald
Meland)
* List of plugin directories in BZR_PLUGIN_PATH environment variable is
now parsed properly under Windows. (Alexander Belchenko)
* Show number of revisions pushed/pulled/merged. (Robey Pointer)
* Keep a cached copy of the basis inventory to speed up operations
that need to refer to it. (Johan Rydberg, Martin Pool)
* Fix bugs in bzr status display of non-ascii characters. (Martin
Pool)
* Remove Makefile.in from default ignore list. (#6413, Tollef Fog
Heen, Martin Pool)
* Fix failure in 'bzr added'. (Nathan McCallum, Martin Pool)
TESTING:
* Fix selftest asking for passwords when there are no SFTP keys.
(Robey Pointer, Jelmer Vernooij)
* Fix selftest run with 'python -O'. (Martin Pool)
* Fix HTTP tests under Windows. (John Arbash Meinel)
* Make tests work even if HOME is not set (Aaron Bentley)
* Updated build_tree to use fixed line-endings for tests which read
the file cotents and compare. Make some tests use this to pass under
Windows. (John Arbash Meinel)
* Skip stat and symlink tests under Windows. (Alexander Belchenko)
* Delay in selftest/testhashcash is now issued under win32 and Cygwin.
(John Arbash Meinel)
* Use terminal width to align verbose test output. (Martin Pool)
* Blackbox tests are maintained within the bzrlib.tests.blackbox directory.
If adding a new test script please add that to
bzrlib.tests.blackbox.__init__. (Robert Collins)
* Much better error message if one of the test suites can't be
imported. (Martin Pool)
* Make check now runs the test suite twice - once with the default locale,
and once with all locales forced to C, to expose bugs. This is not
trivially done within python, so for now its only triggered by running
Make check. Integrators and packagers who wish to check for full
platform support should run 'make check' to test the source.
(Robert Collins)
* Tests can now run TestSkipped if they can't execute for any reason.
(Martin Pool) (NB: TestSkipped should only be raised for correctable
reasons - see the wiki spec ImprovingBzrTestSuite).
