<p>This release marks the start of another long-term-stable series. From here, we
will only make bugfix releases on the 2.3 series (2.3.1, etc, and support it
until August 2012), while 2.4 will become our new development series. The 2.1
and 2.2 series will also continue to get bugfixes. (Currently 2.0 is planned
to be EOLed circa September 2011 and will receive only critical bugfixes.)</p>
<p>This is a bugfix and polish release over the 2.2 series, with a large number
of bugs fixed (>130), and some performance improvements. Some features have
been enhanced including commits on stacked branches, upgrades of related
branches, shortcut URL schemes for ubuntu and debian on launchpad and better
conflict resolution.</p>
<p>Only bugfixes from other stables series have been included since 2.3b5 so all
known fixed bugs are included here.</p>
<p>Users are encouraged to upgrade from the other stable series.</p>

<p>This is the fifth and <strong>last</strong> beta of the 2.3 series, leading up to a 2.3.0
release in February. Beta releases are suitable for everyday use but may cause
some incompatibilities with plugins.</p>
<p>2.3b5 includes bug fixes for committing to stacked branches, smoother upgrades
of multiple branches, compatibility with python-2.7, full test suite passing
on Ubuntu Natty and windows, less round-trips for several smart server
operations, better support text conflicts resolve actions and some more.</p>
<p>All known fixed bugs in other series (2.0, 2.1, 2.2) are also included here.</p>

<li>A redundant parent inventories calculation was removed from
<code class="docutils literal notranslate"><span class="pre">fetch.py</span></code>, as <code class="docutils literal notranslate"><span class="pre">Repository.insert_stream</span></code> already reports any

<li><code class="docutils literal notranslate"><span class="pre">ControlDir.sprout</span></code> no longer opens the target repository more than
once. This avoids some unnecessary IO, and removes a network roundtrip

<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">modified</span></code> now read-locks the working tree (and branch and
repository) just once. (Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">resolve</span></code> now accepts <code class="docutils literal notranslate"><span class="pre">--take-this</span></code> and <code class="docutils literal notranslate"><span class="pre">--take-other</span></code> actions
for text conflicts. This <em>replace</em> the whole file with the content
designated by the action. This will <em>ignore</em> all differences that would
have been merge cleanly otherwise. (Vincent Ladeuil, #638451)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">tags</span></code>’s “sort” argument now allows registering custom sort

<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">break-lock</span></code> on a corrupted lock file works correctly, rather than
raising a PermissionDenied error. We were accidentally holding open the

<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">update</span></code> in a checkout of a readonly branch works again, without
trying to set the tags in the master branch. This had been broken by the
bug fix for bug #603395. (John Arbash Meinel, #701212)</li>

than <code class="docutils literal notranslate"><span class="pre">Transport.get().read()</span></code>. The SFTP code uses an async message to
close the file handle if you let the handle die from refcounting, while
it uses a synchronous message if you close it directly. This should help
prevent random test suite failures from race conditions.

<li>Stop using <code class="docutils literal notranslate"><span class="pre">bzrlib.tuned_gzip.GzipFile</span></code>. It is incompatible with
python-2.7 and was only used for Knit format repositories, which haven’t
been recommended since 2007. The file itself will be removed in the next
release. (John Arbash Meinel)</li>
<li>The BZR_COLUMNS environment variable can be set to 0 to indicate no
limitation on the width of the terminal. (Neil Martinsen-Burrell, #675652)</li>
<li>Treat WSAECONNABORTED the same as WSAECONNRESET for the purposes of
considering a smart data stream as being interrupted. This fixes a
failure in the windows test suite, that was trying to ensure we cleanly
handled a server disconnect. (John Arbash Meinel, #581311, #686587)</li>
<li>Unshelving changes that occur in a now-unversioned directory now restore
the directory properly rather than crashing.

<li>You are now able to commit directly to a stacked branch. Any needed
parent inventories will be filled in as part of the commit process.

<p>This is the fourth beta of the 2.3 series, leading up to a 2.3.0 release in
February. Beta releases are suitable for everyday use but may cause some
incompatibilities with plugins.</p>
<p>2.3b4 includes bug fixes for the <code class="docutils literal notranslate"><span class="pre">config</span></code> command and conflict
resolution. More changes were made for the test scripts handling to make it
easier to add reproducing recipes to bugs.</p>
<p>It also includes bug fixes from the 2.2.2 release as well as the bug fixes
in the upcoming 2.0.7, 2.1.4 and 2.2.3 releases. This means that all known
fixed bugs at the time of this release are included.</p>

<p>This is the first beta of the 2.3 series, leading up to a 2.3.0
release in January or February. Beta releases are suitable for everyday use
but may cause some incompatibilities with plugins. Some plugins may need
small updates to work with 2.3b1.</p>
<p>2.3b1 includes some performance improvements in both speed and memory
consumption, some preliminary support for generating a texinfo version of
the doc and better support for launchpad. Many changes were made to make
our test suite more robust as well as numerous documentation fixes. It
improves the common infrastructure for dealing with colocated named
branches and foreign branches. We plan to continue with these themes
through the 2.3 series.</p>
<p>It also includes bug fixes for 2.0.6, 2.1.3 and 2.2.1 and over 40 fixes of
its own.</p>

<h3>New Features<a class="headerlink" href="#id45" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Added <code class="docutils literal notranslate"><span class="pre">pre_status</span></code> and <code class="docutils literal notranslate"><span class="pre">post_status</span></code> hooks. This allows plugins
to register custom handlers which will be invoked before/after the
standard status output is displayed. (Parth Malwankar)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">break-lock</span> <span class="pre">--config</span> <span class="pre">[location]</span></code> can now break config files
locks. (Vincent Ladeuil, #525571)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.config.LockableConfig</span></code> is a base class for config files that
needs to be protected against multiple writers. All methods that
change a configuration variable value must be decorated with
@needs_write_lock (set_option() for example).
(Vincent Ladeuil, #525571)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">lp:</span></code> prefix will now use your known username (from
<code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">launchpad-login</span></code>) to expand <code class="docutils literal notranslate"><span class="pre">~</span></code> to your username. For example:
<code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">launchpad-login</span> <span class="pre">user</span> <span class="pre">&&</span> <span class="pre">bzr</span> <span class="pre">push</span> <span class="pre">lp:~/project/branch</span></code> will now
push to <code class="docutils literal notranslate"><span class="pre">lp:~user/project/branch</span></code>. (John Arbash Meinel)</li>
<li>New development format <code class="docutils literal notranslate"><span class="pre">development8-subtree</span></code> which is similar to the
<code class="docutils literal notranslate"><span class="pre">2a</span></code> format and adds subtree support. (Jelmer Vernooij)</li>
</ul>
</div>
<div class="section" id="id46">
<h3>Improvements<a class="headerlink" href="#id46" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Allow using both <code class="docutils literal notranslate"><span class="pre">--using</span></code> and <code class="docutils literal notranslate"><span class="pre">--diff-options</span></code>.
(Matthäus G. Chajdas, #234708)</li>
<li>Allow using non-integer bug ID with generic bug trackers.
(Alexandre Garnier, #440472)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">remove</span></code> now just backs up changed files instead of exiting,
forcing you to choose to either keep or delete them. Bazaar will now delete
the files if they can easily be recovered using revert, otherwise they
will be backed up (adding an extension of the form .~#~).
(Marius Kruger, #400554)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">revert</span></code> and <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">status</span></code> are up to 15% faster on large trees
with many changes by not repeatedly building a list of all file-ids.
(Andrew Bennetts)</li>
<li>Decrease memory consumption when many chk index pages are loaded. (Such
as during <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">co</span></code> or <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">ls</span> <span class="pre">-R</span></code> of a large tree.) Often we need to
read many chk pages because the individual chk map nodes will be spread
randomly. Peak memory for ‘bzr ls -R’ on a large tree dropped from 396MB
down to 247MB, expect even more significant savings on 64-bit platforms.
(John Arbash Meinel)</li>
<li>Decrease peak memory during <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">send</span></code>. The old code was caching all
text content and all inventory strings for all revisions before
computing the diffs. Now we only cache as long as there is a child that
will need them. Sending 2000 bzr revisions drops from 1.2GB peak to
256MB peak. (John Arbash Meinel, #614576)</li>
<li><code class="docutils literal notranslate"><span class="pre">DirState</span></code> internals use a little bit less memory. For bzr.dev it
drops the memory from 1MB down to about 800kB. And replaces a few
thousand tuples and sets with StaticTuple. (John Arbash Meinel)</li>
<li>Inventory entries now consume less memory (on 32-bit Ubuntu file entries
have dropped from 68 bytes to 40, and directory entries from 120 bytes
to 48). (Andrew Bennetts)</li>
<li>Reduce peak memory by one copy of compressed text when writing to pack
repositories.
(John Arbash Meinel, #566940)</li>
<li>When building new working trees, default to reading from the repository
rather than the source tree unless explicitly requested. (via
<code class="docutils literal notranslate"><span class="pre">--files-from</span></code> and <code class="docutils literal notranslate"><span class="pre">--hardlink</span></code> for <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">branch</span></code> and
<code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">checkout</span></code>. Generally, 2a format repositories extract
content faster than seeking and reading content from another tree,
especially in cold-cache situations. (John Arbash Meinel, #607298)</li>
<li>Add <code class="docutils literal notranslate"><span class="pre">__pycache__</span></code> to the default <code class="docutils literal notranslate"><span class="pre">ignores</span></code> file. Future releases of
Python will use this directory to store bytecodes.

marked versioned too.
(Martin Pool, #192859)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">clean-tree</span></code> issues a warning if it is unable to delete a file
due to <code class="docutils literal notranslate"><span class="pre">errno.EACCES</span></code> instead of exiting with an error on Windows.
(Parth Malwankar, #430785)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">commit</span> <span class="pre">SYMLINK</span></code> now works, rather than trying to commit the

the revision-id. (Aaron Bentley, #614404)</li>
<li>Configuration files in <code class="docutils literal notranslate"><span class="pre">${BZR_HOME}</span></code> are now written in an atomic
way which should help avoid problems with concurrent writers.

concurrent writers by using a lock. (Vincent Ladeuil, #525571)</li>
<li>Cope with Microsoft FTP Server and VSFTPd that return reply ‘250
Directory created’ when mkdir succeeds. (Martin Pool, #224373)</li>
<li><cite>decode</cite> parameter to get() method in FtpTransport and GioTransport classes
is deprecated. (Alexander Belchenko)</li>
<li>Don’t print internal object name when print an invalid revision spec
error. (Neil Martinsen-Burrell, #598701)</li>
<li>Don’t traceback when a lockdir’s <code class="docutils literal notranslate"><span class="pre">held/info</span></code> file is corrupt (e.g.
contains only NUL bytes). Instead warn the user, and allow <code class="docutils literal notranslate"><span class="pre">bzr</span>
<span class="pre">break-lock</span></code> to remove it. (Andrew Bennetts, #619872)</li>
<li><code class="docutils literal notranslate"><span class="pre">EPIPE</span></code> can be raised during test server shutdown. This happened on
gentoo only so far. (Vincent Ladeuil, #627277)</li>
<li>Errors occurring during HTTP(S) test server starts should now be
handled cleanly. (Vincent Ladeuil, #392402)</li>
<li>Fix <code class="docutils literal notranslate"><span class="pre">AttributeError</span> <span class="pre">on</span> <span class="pre">parent.children</span></code> when adding a file under a
directory that was a symlink in the previous commit.
(Martin Pool, #192859)</li>
<li>Fix <code class="docutils literal notranslate"><span class="pre">AttributeError:</span> <span class="pre">'NoneType'</span> <span class="pre">object</span> <span class="pre">has</span> <span class="pre">no</span> <span class="pre">attribute</span> <span class="pre">'close'</span></code> in
<code class="docutils literal notranslate"><span class="pre">_close_ssh_proc</span></code> when using <code class="docutils literal notranslate"><span class="pre">bzr+ssh://</span></code>. This was causing
connections to pre-1.6 bzr+ssh servers to fail, and causing warnings on
stderr in some other circumstances. (Andrew Bennetts, #633745)</li>
<li>Fix spurious paramiko warning on hardy by ensuring that <code class="docutils literal notranslate"><span class="pre">selftest</span></code>
properly remove its warning filter. (Vincent Ladeuil, #625686)</li>
<li>Fix <code class="docutils literal notranslate"><span class="pre">AttributeError</span> <span class="pre">on</span> <span class="pre">parent.children</span></code> when adding a file under a
directory that was a symlink in the previous commit.
(Martin Pool, #192859)</li>
<li>Fix <code class="docutils literal notranslate"><span class="pre">AttributeError:</span> <span class="pre">'NoneType'</span> <span class="pre">object</span> <span class="pre">has</span> <span class="pre">no</span> <span class="pre">attribute</span> <span class="pre">'close'</span></code> in
<code class="docutils literal notranslate"><span class="pre">_close_ssh_proc</span></code> when using <code class="docutils literal notranslate"><span class="pre">bzr+ssh://</span></code>. This was causing
connections to pre-1.6 bzr+ssh servers to fail, and causing warnings on
stderr in some other circumstances. (Andrew Bennetts, #633745)</li>
<li>Fix a problem in bzr’s <code class="docutils literal notranslate"><span class="pre">Makefile</span></code> that meant syntax errors in some
parts of bzr’s source code could cause <code class="docutils literal notranslate"><span class="pre">make</span> <span class="pre">check-nodocs</span></code> to
incorrectly return an exit code of 0.
(Vincent Ladeuil, #626667)</li>
<li><code class="docutils literal notranslate"><span class="pre">HTTP/1.1</span></code> test servers now set a <code class="docutils literal notranslate"><span class="pre">Content-Length</span></code> header to comply
with pedantic <code class="docutils literal notranslate"><span class="pre">HTTP/1.1</span></code> clients. (Vincent Ladeuil, #568421)</li>
<li>Most of the leaked threads during selftest are now fixed, allowing the
full test suite to pass on gentoo.
(Vincent Ladeuil, #392127)</li>
<li>Only call <code class="docutils literal notranslate"><span class="pre">setlocale</span></code> in the bzr startup script on posix systems. This
avoids an issue with the newer windows C runtimes used by Python 2.6 and
later which can mangle bytestrings printed to the console.
(Martin [gz], #631350)</li>
<li><cite>PathNotChild</cite> should not give a traceback.
(Martin Pool, #98735)</li>
<li>Prevent <code class="docutils literal notranslate"><span class="pre">CHKMap.apply_delta</span></code> from generating non-canonical CHK maps,
which can result in “missing referenced chk root keys” errors when
fetching from repositories with affected revisions.
(Andrew Bennetts, #522637)</li>
<li>Raise ValueError instead of a string exception.
(John Arbash Meinel, #586926)</li>
<li>Repositories accessed via a smart server now reject being stacked on a
repository in an incompatible format, as is the case when accessing them
via other methods. This was causing fetches from those repositories via
a smart server (e.g. using <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">branch</span></code>) to receive invalid data.
(Andrew Bennetts, #562380)</li>
<li>Selftest with versions of subunit that support <code class="docutils literal notranslate"><span class="pre">stopTestRun</span></code> will no longer
error. This error was caused by 2.0 not being updated when upstream
python merged the end of run patch, which chose <code class="docutils literal notranslate"><span class="pre">stopTestRun</span></code> rather than
<code class="docutils literal notranslate"><span class="pre">done</span></code>. (Robert Collins, #571437)</li>

being thrown from <code class="docutils literal notranslate"><span class="pre">xml_serializer</span></code> on certain cElementTree setups.
(Martin [gz], #254278)</li>
<li>strace test-helper tests cope with the new Ubuntu policy of not allowing
users to attach to their own processes by default.
(Martin Pool, #626679)</li>
<li>Test classes like <code class="docutils literal notranslate"><span class="pre">TestCase</span></code>, <code class="docutils literal notranslate"><span class="pre">TestLoader</span></code>, and <code class="docutils literal notranslate"><span class="pre">TestSuite</span></code> should
be available from <code class="docutils literal notranslate"><span class="pre">bzrlib.tests.*</span></code>. They used to be, but were
accidentally removed. (John Arbash Meinel, #627438)</li>
<li><code class="docutils literal notranslate"><span class="pre">Transport.stat</span></code> on a symlink, including a transport pointing directly
to a symlink, now returns information about the symlink.
(Martin Pool)</li>
<li>Upgrading or fetching from a non-rich-root repository to a rich-root
repository (e.g. from pack-0.92 to 2a) no longer fails with
<code class="docutils literal notranslate"><span class="pre">'Inter1and2Helper'</span> <span class="pre">object</span> <span class="pre">has</span> <span class="pre">no</span> <span class="pre">attribute</span> <span class="pre">'source_repo'</span></code>. This was

<<a class="reference external" href="https://launchpad.net/bzr-usertest">https://launchpad.net/bzr-usertest</a>> is an actively-maintained
macrobenchmark suite.
(Martin Pool)</li>
<li>The test suite now simply holds log files in memory, rather than writing them
out to disk and then reading them back in and deleting them.
(Andrew Bennetts)</li>
<li>The way <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">selftest</span> <span class="pre">--parallel</span></code> generates N partitions of tests to
run in parallel has changed. Instead of splitting the list of tests at
N-1 points, it distributes the tests one-by-one into the partitions in a
round robin fashion. This reduces the total time to run the tests in
parallel because a series of slow tests in the test suite will be
distributed evenly among the parallel test suites, rather than slowing
down just one suite. (Andrew Bennetts)</li>
<li>Tracebacks from a parameterized test are no longer reported against every
parameterization of that test. This was done by adding a hack to
<code class="docutils literal notranslate"><span class="pre">bzrlib.tests.clone_test</span></code> so that it no longer causes
testtools.TestCase instances to share a details dict.
