<li>Lightweight checkouts of remote repositories had a bug with how they

they consumed the stream.) (John Arbash Meinel, #1046284)</li>
<li><code class="docutils literal notranslate"><span class="pre">osutils.send_all</span></code> now detects if we get a series of zero bytes sent,
and fails with a ECONNRESET. It seems if paramiko gets disconnected, it
will get into a state where it returns 0 bytes sent, but doesn’t raise
an error. This change allows us to get a couple hiccups of no content
sent, but if it is consistent, we will consider it to be a failure.

This shouldn’t be treated as a fatal error.

<p>This release marks the start of a new long-term-stable series. From here, we
will only make bugfix releases on the 2.5 series (2.5.1, etc, and support it
until April 2017), while 2.6 will become our new development series.</p>
<p>This is a bugfix and polish release over the 2.4 series, with a large number
of bugs fixed (~170 for the 2.5 series alone). The 2.5 series provides a
faster smart protocol implementation for many operations, basic support for
colocated branches. We have started translating bzr with the 2.5 series:
<a class="reference external" href="https://translations.launchpad.net/bzr">https://translations.launchpad.net/bzr</a>, more than 20 languages have already
been registered but these are the early days, contributions welcome.</p>
<p>Only a few bugfixes have been included since 2.5b6 so all known fixed bugs
are included here.</p>
<p>Users are encouraged to upgrade from the other stable series.</p>

<li>A new <code class="docutils literal notranslate"><span class="pre">-O</span></code> standard option (common to all commands) have been added. It
provides a value for a config option in the <code class="docutils literal notranslate"><span class="pre">-Oname=value</span></code> form that
takes precedence over all definitions found in config files. It can be
used multiple times to override different options.
(Vincent Ladeuil, #491196)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">log</span></code> now has an option called <code class="docutils literal notranslate"><span class="pre">--omit-merges</span></code> to omit
those commits that merged branches, i.e. those having more than one
parent.
In order to avoid confusion, the previous command line option
<code class="docutils literal notranslate"><span class="pre">--include-merges</span></code> has been renamed to <code class="docutils literal notranslate"><span class="pre">--include-merged</span></code>.
The old name of the command line option will still be accepted.

variable <code class="docutils literal notranslate"><span class="pre">serve.client_timeout</span></code> or in the command line parameter
<code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">serve</span> <span class="pre">--client-timeout=X</span></code>. Further, it is possible to request
<code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">serve</span> <span class="pre">[--inet]</span></code> to shutdown gracefully by sending SIGHUP. It will
finish the current request, and then close the connection.

<li>New method <code class="docutils literal notranslate"><span class="pre">Tree.get_file_verifier</span></code> which allows tree implementations
to return non-sha1 checksums to verify files.
(Jelmer Vernooij, #720831)</li>
<li>New methods <code class="docutils literal notranslate"><span class="pre">get_transport_from_path</span></code> and <code class="docutils literal notranslate"><span class="pre">get_transport_from_url</span></code>
have been added that only support opening from a path or a URL,
unlike <code class="docutils literal notranslate"><span class="pre">get_transport</span></code>. (Jelmer Vernooij)</li>
<li>New registry <code class="docutils literal notranslate"><span class="pre">OptionRegistry</span></code> specialized for configuration options.
(Vincent Ladeuil)</li>
<li>Remove <code class="docutils literal notranslate"><span class="pre">AtomicFile.closed</span></code> which has been deprecated in bzr 0.10.
(Vincent Ladeuil)</li>
<li>Remove <code class="docutils literal notranslate"><span class="pre">commands._builtin_commands</span></code>, <code class="docutils literal notranslate"><span class="pre">commands.shlex_split_unicode</span></code>,
<code class="docutils literal notranslate"><span class="pre">Command._maybe_expand_globs</span></code> and <code class="docutils literal notranslate"><span class="pre">Command.run_direct</span></code> deprecated in
2.10 and 2.2.0. (Vincent Ladeuil)</li>
<li>Remove <code class="docutils literal notranslate"><span class="pre">diff.get_trees_and_branches_to_diff</span></code> deprecated in 2.2.0.</li>
<li>Remove <code class="docutils literal notranslate"><span class="pre">log.calculate_view_revisions</span></code>, <code class="docutils literal notranslate"><span class="pre">log._filter_revision_range</span></code>,
<code class="docutils literal notranslate"><span class="pre">log.get_view_revisions</span></code> which have been deprecated in bzr 2.1.0. Also
remove <code class="docutils literal notranslate"><span class="pre">log.show_one_log</span></code> which was never properly deprecated but wasn’t
used and is easy to inline if needed. (Vincent Ladeuil)</li>
<li>Remove <code class="docutils literal notranslate"><span class="pre">trace.info</span></code>, <code class="docutils literal notranslate"><span class="pre">trace.error</span></code> and <code class="docutils literal notranslate"><span class="pre">trace.show_log_error</span></code>
deprecated in 2.1.0. (Vincent Ladeuil)</li>
<li>Remove <code class="docutils literal notranslate"><span class="pre">TransportListRegistry.set_default_transport</span></code>, as the concept of
a default transport is currently unused. (Jelmer Vernooij)</li>
<li>Remove <code class="docutils literal notranslate"><span class="pre">UIFactory.warn_cross_format_fetch</span></code> and
<code class="docutils literal notranslate"><span class="pre">UIFactory.warn_experimental_format_fetch</span></code> in favor of
<code class="docutils literal notranslate"><span class="pre">UIFactory.show_user_warning</span></code>. (Jelmer Vernooij)</li>
<li><code class="docutils literal notranslate"><span class="pre">Tags</span></code> containers can now declare whether they support versioned
tags and whether tags can refer to ghost tags.
(Jelmer Vernooij)</li>
<li><code class="docutils literal notranslate"><span class="pre">Tags.merge_to</span></code> now returns a dictionary with the updated tags
and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)</li>
<li>There is a new class <cite>ContentFilterTree</cite> that provides a facade for
content filtering. The <cite>filtered</cite> parameter to <cite>export</cite> is deprecated
in favor of passing a filtered tree, and the specific exporter plugins
no longer support it.
(Martin Pool)</li>
<li><code class="docutils literal notranslate"><span class="pre">Transport</span></code> now has a <code class="docutils literal notranslate"><span class="pre">_parsed_url</span></code> attribute instead of
separate <code class="docutils literal notranslate"><span class="pre">_user</span></code>, <code class="docutils literal notranslate"><span class="pre">_password</span></code>, <code class="docutils literal notranslate"><span class="pre">_port</span></code>, <code class="docutils literal notranslate"><span class="pre">_scheme</span></code>, <code class="docutils literal notranslate"><span class="pre">_host</span></code>
and <code class="docutils literal notranslate"><span class="pre">_path</span></code> attributes. Proxies are provided for the moment but
may be removed in the future. (Jelmer Vernooij)</li>

<div class="section" id="id54">
<h3>Internals<a class="headerlink" href="#id54" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>A new debug flag <code class="docutils literal notranslate"><span class="pre">hpss_client_no_vfs</span></code> will now cause the HPSS client
to raise a <code class="docutils literal notranslate"><span class="pre">HpssVfsRequestNotAllowed</span></code> exception when a VFS request
is attempted. (Jelmer Vernooij)</li>
<li>New method <code class="docutils literal notranslate"><span class="pre">ControlDir._get_selected_branch</span></code> which returns the
colocated branch selected using path segment parameters.
(Jelmer Vernooij, #380871)</li>
</ul>

<div class="section" id="id55">
<h3>Testing<a class="headerlink" href="#id55" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Blackbox tests (including test scripts) can be debugged interactively (see
bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)</li>
<li><cite>BranchBuilder.build_snapshot</cite> now supports a “flush” action. This
cleanly and reliably allows tests using <cite>BranchBuilder</cite> to construct
branches that e.g. rename files out of a directory and unversion that
directory in the same revision. Previously some changes were impossible
due to the order that <cite>build_snapshot</cite> performs its actions.
(Andrew Bennetts)</li>
<li>Don’t require <code class="docutils literal notranslate"><span class="pre">os.fdatasync</span></code> to be defined on all supported OSes
(BSD-based OSes don’t define it). (Vincent Ladeuil, #822649)</li>
<li>Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)</li>
<li><code class="docutils literal notranslate"><span class="pre">LockDir</span></code> can now be run when the local hostname is <code class="docutils literal notranslate"><span class="pre">localhost</span></code>.
(Jelmer Vernooij, #825994)</li>
<li><code class="docutils literal notranslate"><span class="pre">ModuleAvailableFeature</span></code> won’t try to import already imported modules,
allowing it to be used for modules with side-effects.
(Vincent Ladeuil, #712474)</li>
<li>Output time stamps while running <code class="docutils literal notranslate"><span class="pre">make</span> <span class="pre">check</span></code> to get better timings from
pqm. (Vincent Ladeuil, #837926)</li>
<li><cite>TestCaseWithMemoryTransport</cite> is faster now: <cite>_check_safety_net</cite> now
just compares the bytes in the dirstate file to its pristine state,
rather than opening the WorkingTree and calling <code class="docutils literal notranslate"><span class="pre">last_revision()</span></code>.
This reduces the overall test suite time by about 10% on my laptop.
(Andrew Bennetts)</li>
<li>Update <cite>TestCase.knownFailure</cite> to the testtools way of handling expected
failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)</li>
