<li>Committing directly to a stacked branch from a lightweight checkout will
no longer work. In previous versions this would appear to work but would
generate repositories with insufficient data to create deltas, leading
to later errors when branching or reading from the repository.

<h2>Bug Fixes<a class="headerlink" href="#bug-fixes" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li>Fetching from 2a branches from a version-2 bzr protocol would fail to
copy the internal inventory pages from the CHK store. This cannot happen
in normal use as all 2a compatible clients and servers support the
version-3 protocol, but it does cause test suite failures when testing
downlevel protocol behaviour. (Robert Collins)</li>
<li>Fix a test failure on karmic by making a locale test more robust.
(Vincent Ladeuil, #413514)</li>
<li>Fixed “Pack ... already exists” error when running <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">pack</span></tt> on a
fully packed 2a repository. (Andrew Bennetts, #382463)</li>
<li>Further tweaks to handling of <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">add</span></tt> messages about ignored files.
(Jason Spashett, #76616)</li>
<li>Properly handle fetching into a stacked branch while converting the
data, especially when there are also ghosts. The code was filling in
parent inventories incorrectly, and also not handling when one of the
parents was a ghost. (John Arbash Meinel, #402778, #412198)</li>
<li><tt class="docutils literal"><span class="pre">RemoteStreamSource.get_stream_for_missing_keys</span></tt> will fetch CHK
inventory pages when appropriate (by falling back to the vfs stream
source). (Andrew Bennetts, #406686)</li>
<li>StreamSource generates rich roots from non-rich root sources correctly
now. (Andrew Bennetts, #368921)</li>
<li>When deciding whether a repository was compatible for upgrading or
fetching, we previously incorrectly checked the default repository
format for the bzrdir format, rather than the format that was actually
present on disk. (Martin Pool, #408824)</li>
</ul>
</div>
<div class="section" id="improvements">
<h2>Improvements<a class="headerlink" href="#improvements" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li>A better description of the platform is shown in crash tracebacks, <tt class="docutils literal"><span class="pre">bzr</span>
<span class="pre">--version</span></tt> and <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">selftest</span></tt>.
(Martin Pool, #409137)</li>
<li>Cross-format fetches (such as between 1.9-rich-root and 2a) via the
smart server are more efficient now. They send inventory deltas rather
than full inventories. The smart server has two new requests,
<tt class="docutils literal"><span class="pre">Repository.get_stream_1.19</span></tt> and <tt class="docutils literal"><span class="pre">Repository.insert_stream_1.19</span></tt> to
support this. (Andrew Bennetts, #374738, #385826)</li>
<li>Extracting the full ancestry and computing the <tt class="docutils literal"><span class="pre">merge_sort</span></tt> is now
significantly faster. This effects things like <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">-n0</span></tt>. (For
example, <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">-r</span> <span class="pre">-10..-1</span> <span class="pre">-n0</span> <span class="pre">bzr.dev</span></tt> is 2.5s down to 1.0s.

<ul class="simple">
<li><tt class="docutils literal"><span class="pre">-Dstrict_locks</span></tt> can now be used to check that read and write locks
are treated properly w.r.t. exclusivity. (We don’t try to take an OS
read lock on a file that we already have an OS write lock on.) This is
now set by default for all tests, if you have a test which cannot be
fixed, you can use <tt class="docutils literal"><span class="pre">self.thisFailsStrictLockCheck()</span></tt> as a
compatibility knob. (John Arbash Meinel)</li>
<li>InterDifferingSerializer is now only used locally. Other fetches that
would have used InterDifferingSerializer now use the more network
friendly StreamSource, which now automatically does the same
transformations as InterDifferingSerializer. (Andrew Bennetts)</li>
<li><tt class="docutils literal"><span class="pre">KnownGraph</span></tt> now has a <tt class="docutils literal"><span class="pre">.topo_sort</span></tt> and <tt class="docutils literal"><span class="pre">.merge_sort</span></tt> member which
are implemented in pyrex and significantly faster. This is exposed along
with <tt class="docutils literal"><span class="pre">CombinedGraphIndex.find_ancestry()</span></tt> as
<tt class="docutils literal"><span class="pre">VersionedFiles.get_known_graph_ancestry(keys)</span></tt>.
(John Arbash Meinel)</li>
<li>RemoteBranch.open now honours ignore_fallbacks correctly on bzr-v2
protocols. (Robert Collins)</li>
<li>The index code now has some specialized routines to extract the full
ancestry of a key in a more efficient manner.
<tt class="docutils literal"><span class="pre">CombinedGraphIndex.find_ancestry()</span></tt>. (Time to get ancestry for
bzr.dev drops from 1.5s down to 300ms. For OOo from 33s => 10.5s) (John
Arbash Meinel)</li>
