<ul class="simple">
<li>Cope with Unix filesystems, such as smbfs, where chmod gives ‘permission
denied’. (Martin Pool, #606537)</li>
<li>During merges, when two entries end up using the same path for two
different file-ids (the same file being ‘bzr added’ in two different
branches) , ‘duplicate’ conflicts are created instead of ‘content’
ones. This was previously leading to a ‘Malformed tramsform’ exception.
(Vincent Ladeuil, #880701)</li>
<li>Fix a traceback when trying to checkout a tree that also has an entry
with file-id <cite>TREE_ROOT</cite> somewhere other than at the root directory.
(John Arbash Meinel, #830947)</li>
<li>Handle when an uncommit/update tries to add a file to an otherwise empty
directory. The <code class="docutils literal notranslate"><span class="pre">Dirstate.update_basis_by_delta</span></code> would end up
incorrectly flagging the delta as invalid. (Brian de Alwis, #855155)</li>
<li>‘Malformed transform’ exceptions are now recognized as internal errors
instead of user errors and report a traceback. This will reduce user
confusion as there is generally nothing users can do about them.
(Vincent Ladeuil, #880701)</li>
<li>Prevent a traceback being printed to stderr when logging has problems and
accept utf-8 byte string without breaking. (Martin Packman, #714449)</li>
<li>Some filesystems give <code class="docutils literal notranslate"><span class="pre">EOPNOTSUPP</span></code> when trying to call <code class="docutils literal notranslate"><span class="pre">fdatasync</span></code>.
This shouldn’t be treated as a fatal error.
(John Arbash Meinel, #1075108)</li>
<li>Teach the bzr client how to reconnect if we get <code class="docutils literal notranslate"><span class="pre">ConnectionReset</span></code>
while making an RPC request. This doesn’t handle all possible network
disconnects, but it should at least handle when the server is asked to
shutdown gracefully. This is a backport of the functionality in bzr-2.5.
(John Arbash Meinel, #819604)</li>
<li>Use <code class="docutils literal notranslate"><span class="pre">encoding_type='exact'</span></code> for <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">testament</span></code> so that on Windows
the sha hash of the long testament matches the sha hash in the short
form. (John Arbash Meinel, #1010339)</li>
<li>When the <code class="docutils literal notranslate"><span class="pre">limbo</span></code> or <code class="docutils literal notranslate"><span class="pre">pending-deletion</span></code> directories exist, typically
because of an interrupted tree update, but are empty, bzr no longer
errors out, because there is nothing for the user to clean up. Also,
errors in creation of these directories are no longer squelched.
(Martin Pool, #427773)</li>
<li>_Win32Stat object provides members st_uid and st_gid, those are present
in Python’s os.stat object. These members required for external tools like
bzr-git and dulwich. (Alexander Belchenko, #967060)</li>

<p>This release marks the start of a new long-term-stable series. From here, we
will only make bugfix releases on the 2.4 series (2.4.1, etc, and support it
until February 2013), while 2.5 will become our new development series.</p>
<p>This is a bugfix and polish release over the 2.3 series, with a large number
of bugs fixed (>150 for the 2.4 series alone), and some performance
improvements. Support for python 2.4 and 2.5 has been dropped, many large
working tree operations have been optimized as well as some stacked branches
operations.</p>
<p>Only bugfixes from other stables series have been included since 2.4b5 so
all known fixed bugs are included here.</p>
<p>Users are encouraged to upgrade from the other stable series.</p>

cleanly and reliably allows tests using <cite>BranchBuilder</cite> to construct

parameter that can be set in bazaar.conf.
<code class="docutils literal notranslate"><span class="pre">bzr.groupcompress.max_entries_per_source</span></code> default of 65536.
When doing compression, we build up an index of locations to match
against. Setting this higher will result in slightly better compression,
at a cost of more memory. Note that a value of 65k represents fully
sampling a 1MB file. So this only has an effect when compressing texts
larger than N*16 bytes. (John Arbash Meinel, #602614)</li>

<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">branch</span> <span class="pre">--stacked</span></code> from a smart server uses the network a little
more efficiently. For a simple branch it reduces the number of
round-trips by about 20%. (Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">--line</span></code> scales the width of the author field with the size of

<code class="docutils literal notranslate"><span class="pre">CHKInventory.iter_changes</span></code> rather than the slow generic
inter-Inventory changes. It used to use a <code class="docutils literal notranslate"><span class="pre">DirStateRevisionTree</span></code> as
one of the source trees, which is faster when we have to read the whole
inventory anyway, but much slower when we can get just the delta out of
the repository. On a 70k record tree, this changes <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">pull</span></code> from 28s
down to 17s. (John Arbash Meinel, #780677)</li>
<li>Slightly reduced memory consumption when fetching into a 2a repository
by reusing existing caching a little better. (Andrew Bennetts)</li>
<li>Speed up <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">status</span></code> by a little bit when there are a couple of
modified files. We now track how many files we have seen that need
updating, and only rewrite the dirstate file if enough of them have
changed. The default is 10, and can be overridden by setting the branch
option “<code class="docutils literal notranslate"><span class="pre">bzr.workingtree.worth_saving_limit</span></code>”.

WorkingTree. (John Arbash Meinel, #759091)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">revert</span></code> now properly uses <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">status</span></code>’s optimized
<code class="docutils literal notranslate"><span class="pre">iter_changes</span></code>. This can be a significant performance difference (33s
to 5s on large trees). (John Arbash Meinel, #759096)</li>
<li>Resolve <code class="docutils literal notranslate"><span class="pre">lp:FOO</span></code> urls locally rather than doing an XMLRPC request if
the user has done <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">launchpad-login</span></code>. The bzr+ssh URLs were already
being handed off to the remote server anyway (xmlrpc has been mapping
<code class="docutils literal notranslate"><span class="pre">lp:bzr</span></code> to <code class="docutils literal notranslate"><span class="pre">bzr+ssh://bazaar.launchpad.net/+branch/bzr</span></code>, rather
than <code class="docutils literal notranslate"><span class="pre">bzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev</span></code> for a few
months now.) By doing it ourselves, we can cut out substantial startup
time. From Netherlands to London it was taking 368ms to do the XMLRPC
call as much as 2s from Sydney. You can test the local logic by using
<code class="docutils literal notranslate"><span class="pre">-Dlaunchpad</span></code>. (John Arbash Meinel, #397739)</li>
<li>When building a new WorkingTree (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">branch</span></code>) we now properly store the stat and hash of files that
are old enough. This saves a fair amount of time on the first
<code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">status</span></code> (on a 500MB tree, it saves about 30+s).

<h3>Bug Fixes<a class="headerlink" href="#id51" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Arguments that can’t be decoded to unicode in the current posix locale give
a clearer error message without a traceback. (Martin [gz], #745712)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.log._DEFAULT_REQUEST_PARAMS</span></code> is no longer accidentally
mutated by <code class="docutils literal notranslate"><span class="pre">bzrlib.log._apply_log_request_defaults</span></code>. In practice
these default values aren’t relied on very often so this probably
wasn’t causing any trouble. (Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">log</span></code> now works on revisions which are not in the current branch.
(Matt Giuca, #241998)</li>
<li>Don’t rewrite the dirstate file when non-interesting changes have
occurred. This can significantly improve ‘bzr status’ times when there
are only small changes to a large tree.
(Ian Clatworthy, John Arbash Meinel, #380202)</li>
<li>Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.merge.Merge</span></code> now calls <code class="docutils literal notranslate"><span class="pre">iter_changes</span></code> without
<code class="docutils literal notranslate"><span class="pre">include_unversioned=True</span></code>. This makes it significantly faster in many
cases, because it only looks at modified files, rather than building
information about all files. This can cause failures in other
TreeTransform code, because it had been expecting to know the names of
things which had not changed (such as parent directories). All cases we
know about so far have been fixed, but there may be fallout for edge
cases that we are missing. (John Arbash Meinel, #759091)</li>
<li><code class="docutils literal notranslate"><span class="pre">SFTPTransport</span></code> is more pro-active about closing file-handles. This
reduces the chance of having threads fail from async requests while
running the test suite. (John Arbash Meinel, #656170)</li>
<li>Standalone bzr.exe installation on Windows: user can put additional python
libraries into <code class="docutils literal notranslate"><span class="pre">site-packages</span></code> subdirectory of the installation directory,
this might be required for “installing” extra dependencies for some plugins.
(Alexander Belchenko, #743256)</li>
<li><code class="docutils literal notranslate"><span class="pre">transform.revert()</span></code> has been updated to use
<code class="docutils literal notranslate"><span class="pre">wt.iter_changes(basis_tree)</span></code> rather than
<code class="docutils literal notranslate"><span class="pre">basis_tree.iter_changes(wt)</span></code>. This allows the optimized code path to
kick in, improving <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">revert</span></code> times significantly (33s to 4s on
large trees, 0.7s to 0.3s on small trees.) (John Arbash Meinel, #759096)</li>
<li><code class="docutils literal notranslate"><span class="pre">TreeTransform.create_file/new_file</span></code> can now take an optional <code class="docutils literal notranslate"><span class="pre">sha1</span></code>
parameter. If supplied, when the transform is applied, it will then call
<code class="docutils literal notranslate"><span class="pre">self._tree._observed_sha1</span></code> for those files. This lets us update the
hash-cache for content that we create, preventing us from re-reading the
content in the next <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">status</span></code>. (John Arbash Meinel, #740932)</li>

in GNU format. See <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">help</span> <span class="pre">changelog_merge</span></code> for details.
(Andrew Bennetts)</li>
<li>Configuration options can now use references to other options in the same
file by enclosing them with curly brackets (<code class="docutils literal notranslate"><span class="pre">{other_opt}</span></code>). This makes it
possible to use, for example,
<code class="docutils literal notranslate"><span class="pre">push_location=lp:~vila/bzr/config-{nickname}</span></code> in <code class="docutils literal notranslate"><span class="pre">branch.conf</span></code> when
using a loom. During the beta period, the default behaviour is to disable

<h3>Improvements<a class="headerlink" href="#id58" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>A new hidden command <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">repair-workingtree</span></code>. This is a way to force
the dirstate file to be rebuilt, rather than using a <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">checkout</span></code>
workaround. (John Arbash Meinel)</li>
<li>Added a <code class="docutils literal notranslate"><span class="pre">Branch.heads_to_fetch</span></code> RPC to the smart server protocol.
This allows formats from plugins (such as looms) to efficiently tell the
client which revisions need to be fetched. (Andrew Bennetts)</li>
<li>Branching, merging and pulling a branch now copies revisions named in
tags, not just the tag metadata. (Andrew Bennetts, #309682)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">cat-revision</span></code> no longer requires a working tree.

<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">export</span> <span class="pre">--per-file-timestamps</span></code> for .tar.gz files will now
override the mtime for trees exported on Python 2.7 and later, which
expose the ‘mtime’ field in gzip files. This makes the output of
<code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">export</span> <span class="pre">--per-file-timestamps</span></code> for a particular tree

<li>Getting all entries from <code class="docutils literal notranslate"><span class="pre">CHKInventory.iter_entries_by_dir()</span></code> has been
sped up dramatically for large trees. Iterating by dir is not the best
way to load data from a CHK inventory, so it preloads all the items in
the correct order. (With the gcc-tree, this changes it (re)reading 8GB
of CHK data, down to just 150MB.) This has noticeable affects for things
like building checkouts, etc. (John Arbash Meinel, #737234)</li>

instead. (Jelmer Vernooij, #721971)</li>
<li><code class="docutils literal notranslate"><span class="pre">BzrDirFormat</span></code> has a new attribute <code class="docutils literal notranslate"><span class="pre">fixed_components</span></code> that
indicates whether the components of the bzrdir can be upgraded
independent of the <code class="docutils literal notranslate"><span class="pre">BzrDir</span></code>. (Jelmer Vernooij)</li>
<li><code class="docutils literal notranslate"><span class="pre">BzrProber.register_format</span></code> and <code class="docutils literal notranslate"><span class="pre">BzrProber.unregister_format</span></code> are
now deprecated in favour of the <code class="docutils literal notranslate"><span class="pre">BzrProber.formats</span></code> format registry.
(Jelmer Vernooij)</li>
<li><code class="docutils literal notranslate"><span class="pre">ControlDir</span></code> implementations no longer have to provide the
<code class="docutils literal notranslate"><span class="pre">get_branch_transport</span></code>, <code class="docutils literal notranslate"><span class="pre">get_workingtree_transport</span></code> and
<code class="docutils literal notranslate"><span class="pre">get_repository_transport</span></code> methods. (Jelmer Vernooij, #730325)</li>
<li><code class="docutils literal notranslate"><span class="pre">Converter</span></code> has been moved from <code class="docutils literal notranslate"><span class="pre">bzrlib.bzrdir</span></code> to
<code class="docutils literal notranslate"><span class="pre">bzrlib.controldir</span></code>. (Jelmer Vernooij)</li>
<li>Repository formats can now provide
<code class="docutils literal notranslate"><span class="pre">_get_extra_interrepo_test_combinations</span></code> in the same module
to provide extra test combinations for <code class="docutils literal notranslate"><span class="pre">bzrlib.tests.per_repository</span></code>.
(Jelmer Vernooij)</li>
<li>Repository formats should now be registered on the format registry
(<code class="docutils literal notranslate"><span class="pre">bzrlib.repository.format_registry</span></code>) rather than using the class
methods on <code class="docutils literal notranslate"><span class="pre">RepositoryFormat</span></code>. (Jelmer Vernooij)</li>
<li>Repository formats can now indicate they do not support the full
VersionedFiles API by setting the <code class="docutils literal notranslate"><span class="pre">supports_full_versioned_files</span></code>
attribute to False. A subset of the VersionedFiles API
(signatures and text graphs) still needs to be supported.
(Jelmer Vernooij)</li>
<li>Repository formats have a new method <code class="docutils literal notranslate"><span class="pre">is_deprecated</span></code> that
implementations can override to return True to trigger a deprecation
warning. (Jelmer Vernooij)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">revision_id</span></code> parameter of
<code class="docutils literal notranslate"><span class="pre">Repository.search_missing_revision_ids</span></code> and
<code class="docutils literal notranslate"><span class="pre">InterRepository.search_missing_revision_ids</span></code> is deprecated. It is
replaced by the <code class="docutils literal notranslate"><span class="pre">revision_ids</span></code> parameter. (Andrew Bennetts)</li>
<li>Working tree formats should now be registered on the format registry
(<code class="docutils literal notranslate"><span class="pre">bzrlib.working_tree.format_registry</span></code>) rather than using the class
methods on <code class="docutils literal notranslate"><span class="pre">WorkingTreeFormat</span></code>. (Jelmer Vernooij, #714730)</li>
<li>Exporting may now be done with a generator
(<code class="docutils literal notranslate"><span class="pre">bzrlib.export.get_export_generator</span></code>) (Geoff/xaav, #791005)</li>

<ul class="simple">
<li><code class="docutils literal notranslate"><span class="pre">CatchingExceptionThread</span></code> (formerly ThreadWithException) has been moved
out of the <code class="docutils literal notranslate"><span class="pre">bzrlib.tests</span></code> hierarchy to make it clearer that it can be used
outside of tests. This class makes it easier to track exceptions in threads
by catching them so they can be re-raised in the controlling thread. It’s
available in the <code class="docutils literal notranslate"><span class="pre">bzrlib.cethread</span></code> module. (Vincent Ladeuil)</li>
<li>Correctly propagate malloc failures from diff-delta.c code as MemoryError
so OOM conditions during groupcompress are clearly reported. This entailed a
change to several function signatures. (Martin [gz], #633336)</li>
<li><code class="docutils literal notranslate"><span class="pre">HookPoint.lazy_hook</span></code> and <code class="docutils literal notranslate"><span class="pre">Hooks.install_named_lazy_hook</span></code> can install
