<ul class="simple">
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">export</span></code> can now export a subdirectory of a project.
(Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">remove-tree</span></code> will now refuse to remove a tree with uncommitted
changes, unless the <code class="docutils literal notranslate"><span class="pre">--force</span></code> option is specified.
(Lukáš Lalinský, #74101)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">rm</span></code> will now scan for files that are missing and remove just
them automatically, much as <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">add</span></code> scans for new files that

RFC2228. (Jelmer Vernooij, #49623)</li>
<li>Add support for IPv6 in the smart server. (Jelmer Vernooij, #165014)</li>
</ul>
</div>
<div class="section" id="improvements">
<h3>Improvements<a class="headerlink" href="#improvements" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>A URL like <code class="docutils literal notranslate"><span class="pre">log+file:///tmp</span></code> will log all access to that Transport
to <code class="docutils literal notranslate"><span class="pre">.bzr.log</span></code>, which may help in debugging or profiling.
(Martin Pool)</li>
<li><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">push</span></code> use the default stacking policy if the
branch format supports it. (Aaron Bentley)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">init</span></code> and <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">init-repo</span></code> will now print out the same as
<code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">info</span></code> if it completed successfully.
(Marius Kruger)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">uncommit</span></code> logs the old tip revision id, and displays how to
restore the branch to that tip using <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">pull</span></code>. This allows you
to recover if you realize you uncommitted the wrong thing.
(John Arbash Meinel)</li>
<li>Fix problems in accessing stacked repositories over <code class="docutils literal notranslate"><span class="pre">bzr://</span></code>.
(Martin Pool, #261315)</li>
<li><code class="docutils literal notranslate"><span class="pre">SFTPTransport.readv()</span></code> was accidentally using <code class="docutils literal notranslate"><span class="pre">list</span> <span class="pre">+=</span> <span class="pre">string</span></code>,
which ‘works’, but adds each character separately to the list,
rather than using <code class="docutils literal notranslate"><span class="pre">list.append(string)</span></code>. Fixing this makes the
SFTP transport a little bit faster (~20%) and use a bit less memory.
(John Arbash Meinel)</li>
<li>When reading index files, if we happen to read the whole file in a
single request treat it as a <code class="docutils literal notranslate"><span class="pre">_buffer_all</span></code> request. This happens
most often on small indexes over remote transports, where we default
to reading 64kB. It saves a round trip for each small index during
fetch operations. Also, if we have read more than 50% of an index
file, trigger a <code class="docutils literal notranslate"><span class="pre">_buffer_all</span></code> on the next request. This works
around some inefficiencies because reads don’t fall neatly on page
boundaries, so we would ignore those bytes, but request them again
later. This could trigger a total read size of more than the whole
file. (John Arbash Meinel)</li>

<h3>Bug Fixes<a class="headerlink" href="#id3" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">rm</span></code> is now aliased to <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">del</span></code> for the convenience of svn
users. (Robert Collins, #205416)</li>
<li>Catch the infamous “select/poll returned error” which occurs when
pycurl try to send a body request to an HTTP/1.0 server which has
already refused to handle the request. (Vincent Ladeuil, #225020)</li>
<li>Fix <code class="docutils literal notranslate"><span class="pre">ObjectNotLocked</span></code> errors when using various commands
(including <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">cat</span></code> and <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">annotate</span></code>) in combination with a
smart server URL. (Andrew Bennetts, #237067)</li>
<li><code class="docutils literal notranslate"><span class="pre">FTPTransport.stat()</span></code> would return <code class="docutils literal notranslate"><span class="pre">0000</span></code> as the permission bits
for the containing <code class="docutils literal notranslate"><span class="pre">.bzr/</span></code> directory (it does not implement
permissions). This would cause us to set all subdirectories to
<code class="docutils literal notranslate"><span class="pre">0700</span></code> and files to <code class="docutils literal notranslate"><span class="pre">0600</span></code> rather than leaving them unmodified.
Now we ignore <code class="docutils literal notranslate"><span class="pre">0000</span></code> as the permissions and assume they are
invalid. (John Arbash Meinel, #259855)</li>
<li>Merging from a previously joined branch will no longer cause
a traceback. (Jelmer Vernooij, #203376)</li>
<li>Pack operations on windows network shares will work even with large
files. (Robert Collins, #255656)</li>
<li>Running <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">st</span> <span class="pre">PATH_TO_TREE</span></code> will no longer suppress merge
status. Status is also about 7% faster on mozilla sized trees
when the path to the root of the tree has been given. Users of
the internal <code class="docutils literal notranslate"><span class="pre">show_tree_status</span></code> function should be aware that
the show_pending flag is now authoritative for showing pending
merges, as it was originally. (Robert Collins, #255204)</li>
<li>Set valid default _param_name for Option so that ListOption can embed
‘-‘ in names. (Vincent Ladeuil, #263249)</li>
<li>Show proper error rather than traceback when an unknown revision
id is specified to <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">cat-revision</span></code>. (Jelmer Vernooij, #175569)</li>
<li>Trailing text in the dirstate file could cause the C dirstate parser
to try to allocate an invalid amount of memory. We now properly
check and test for parsing a dirstate with invalid trailing data.
(John Arbash Meinel, #186014)</li>
<li>Unexpected error responses from a smart server no longer cause the
client to traceback. (Andrew Bennetts, #263527)</li>
<li>Use a Windows api function to get a Unicode host name, rather than
assuming the host name is ascii.
(Mark Hammond, John Arbash Meinel, #256550)</li>
<li><code class="docutils literal notranslate"><span class="pre">WorkingTree4</span></code> trees will now correctly report missing-and-new
paths in the output of <code class="docutils literal notranslate"><span class="pre">iter_changes</span></code>. (Robert Collins)</li>

<h3>API Changes<a class="headerlink" href="#api-changes" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Exporters now take 4 parameters. (Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">Tree.iter_changes</span></code> will now return False for the content change
field when a file is missing in the basis tree and not present in
the target tree. Previously it returned True unconditionally.
(Robert Collins)</li>
<li>The deprecated <code class="docutils literal notranslate"><span class="pre">Branch.abspath</span></code> and unimplemented
<code class="docutils literal notranslate"><span class="pre">Branch.rename_one</span></code> and <code class="docutils literal notranslate"><span class="pre">Branch.move</span></code> were removed. (Jelmer Vernooij)</li>
<li>BzrDir.clone_on_transport implementations must now accept a stacked_on

<h3>Testing<a class="headerlink" href="#testing" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><code class="docutils literal notranslate"><span class="pre">addCleanup</span></code> now takes <code class="docutils literal notranslate"><span class="pre">*arguments</span></code> and <code class="docutils literal notranslate"><span class="pre">**keyword_arguments</span></code>
which are then passed to the cleanup callable as it is run. In
addition, addCleanup no longer requires that the callables passed to
it be unique. (Jonathan Lange)</li>
<li>Fix some tests that fail on Windows because files are deleted while
still in use.
(Mark Hammond)</li>
<li><code class="docutils literal notranslate"><span class="pre">selftest</span></code>’s <code class="docutils literal notranslate"><span class="pre">--starting-with</span></code> option can now use predefined
prefixes so that one can say <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">selftest</span> <span class="pre">-s</span> <span class="pre">bp.loom</span></code> instead of

</div>
<div class="section" id="internals">
<h3>Internals<a class="headerlink" href="#internals" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>A new plugin interface, <code class="docutils literal notranslate"><span class="pre">bzrlib.log.log_adapters</span></code>, has been added.
This allows dynamic log output filtering by plugins.
(Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.btree_index</span></code> is now available, providing a b-tree index
layer. The design is memory conservative (limited memory cache),
faster to seek (approx 100 nodes per page, gives 100-way fan out),
and stores compressed pages allowing more keys per page.
(Robert Collins, John Arbash Meinel)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.diff.DiffTree.show_diff</span></code> now skips changes where the kind
is unknown in both source and target.
(Robert Collins, Aaron Bentley)</li>
<li><code class="docutils literal notranslate"><span class="pre">GraphIndexBuilder.add_node</span></code> and <code class="docutils literal notranslate"><span class="pre">BTreeBuilder</span></code> have been
streamlined a bit. This should make creating large indexes faster.
(In benchmarking, it now takes less time to create a BTree index than
it takes to read the GraphIndex one.) (John Arbash Meinel)</li>
<li>Mail clients for <cite>bzr send</cite> are now listed in a registry. This
allows plugins to add new clients by registering them with
<code class="docutils literal notranslate"><span class="pre">bzrlib.mail_client.mail_client_registry</span></code>. All of the built-in
clients now use this mechanism. (Neil Martinsen-Burrell)</li>
