<p>Bazaar 1.10 has several performance improvements for copying revisions
(especially for small updates to large projects). There has also been a
significant amount of effort in polishing stacked branches. The commands
<tt class="docutils literal"><span class="pre">shelve</span></tt> and <tt class="docutils literal"><span class="pre">unshelve</span></tt> have become core commands, with an improved
implementation.</p>
<p>The only changes versus bzr-1.10rc1 are bugfixes for stacked branches.</p>
<div class="section" id="bug-fixes">
<h3>bug Fixes<a class="headerlink" href="#bug-fixes" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Don’t set a pack write cache size from RepoFetcher, because the
cache is not coherent with reads and causes ShortReadvErrors.
This reverses the change that fixed #294479.
(Martin Pool, #303856)</li>
<li>Properly handle when a revision can be inserted as a delta versus
when it needs to be expanded to a fulltext for stacked branches.
There was a bug involving merge revisions. As a method to help
prevent future difficulties, also make stacked fetches sort
topologically. (John Arbash Meinel, #304841)</li>

<p>This release of Bazaar focuses on performance improvements when pushing
and pulling revisions, both locally and to remote networks. The popular
<tt class="docutils literal"><span class="pre">shelve</span></tt> and <tt class="docutils literal"><span class="pre">unshelve</span></tt> commands, used to interactively revert and
restore work in progress, have been merged from bzrtools into the bzr
core. There are also bug fixes for portability, and for stacked branches.</p>

<h3>New Features<a class="headerlink" href="#new-features" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>New <tt class="docutils literal"><span class="pre">commit_message_template</span></tt> hook that is called by the commit
code to generate a template commit message. (Jelmer Vernooij)</li>
<li>New <cite>shelve</cite> and <cite>unshelve</cite> commands allow undoing and redoing changes.
(Aaron Bentley)</li>
</ul>

<div class="section" id="improvements">
<h3>Improvements<a class="headerlink" href="#improvements" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">(Remote)Branch.copy_content_into</span></tt> no longer generates the full revision
history just to set the last revision info.
(Andrew Bennetts, John Arbash Meinel)</li>
<li>Fetches between formats with different serializers (such as
pack-0.92-subtree and 1.9-rich-root) are faster now. This is due to
operating on batches of 100 revisions at time rather than
one-by-one. (Andrew Bennetts, John Arbash Meinel)</li>
<li>Search index files corresponding to pack files we’ve already used
before searching others, because they are more likely to have the
keys we’re looking for. This reduces the number of iix and tix
files accessed when pushing 1 new revision, for instance.
(John Arbash Meinel)</li>
<li>Signatures to transfer are calculated more efficiently in
<tt class="docutils literal"><span class="pre">item_keys_introduced_by</span></tt>. (Andrew Bennetts, John Arbash Meinel)</li>
<li>The generic fetch code can once again copy revisions and signatures
without extracting them completely to fulltexts and then serializing
them back down into byte strings. This is a significant performance
improvement when fetching from a stacked branch.
(John Arbash Meinel, #300289)</li>
<li>When making a large readv() request over <tt class="docutils literal"><span class="pre">bzr+ssh</span></tt>, break up the
request into more manageable chunks. Because the RPC is not yet able
to stream, this helps keep us from buffering too much information at
once. (John Arbash Meinel)</li>
</ul>
</div>
<div class="section" id="id1">
<h3>Bug Fixes<a class="headerlink" href="#id1" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Better message when the user needs to set their Launchpad ID.
(Martin Pool, #289148)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">commit</span> <span class="pre">--local</span></tt> doesn’t access the master branch anymore.
This fixes a regression introduced in 1.9. (Marius Kruger, #299313)</li>
<li>Don’t call the system <tt class="docutils literal"><span class="pre">chdir()</span></tt> with an empty path. Sun OS seems
to give an error in that case. Also, don’t count on <tt class="docutils literal"><span class="pre">getcwd()</span></tt>
being able to allocate a new buffer, which is a gnu extension.
(John Arbash Meinel, Martin Pool, Harry Hirsch, #297831)</li>
<li>Don’t crash when requesting log –forward <file> for a revision range
starting with a dotted revno.
(Vincent Ladeuil, #300055)</li>
<li>Don’t create text deltas spanning stacked repositories; this could
cause “Revision X not present in Y” when later accessing them.
(Martin Pool, #288751)</li>
<li>Pack repositories are now able to reload the pack listing and retry
the current operation if another action causes the data to be
repacked. (John Arbash Meinel, #153786)</li>
<li>PermissionDenied errors from smart servers no longer cause
“PermissionDenied: “None”” on the client.
(Andrew Bennetts, #299254)</li>
<li>Pushing to a stacked pack repository now batches writes, the same
way writes are batched to ordinary pack repository. This makes
pushing to a stacked branch over the network much faster.
(Andrew Bennetts, #294479)</li>
<li>TooManyConcurrentRequests no longer occur when a fetch fails and
tries to abort a write group. This allows the root cause (e.g. a
network interruption) to be reported. (Andrew Bennetts, #297014)</li>
<li>RemoteRepository.get_parent_map now uses fallback repositories.
(Aaron Bentley, #297991?, #293679?)</li>

<div class="section" id="api-changes">
<h3>API Changes<a class="headerlink" href="#api-changes" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">CommitBuilder</span></tt> now validates the strings it will be committing,
to ensure that they do not have characters that will not be properly
round-tripped. For now, it just checks for characters that are
invalid in the XML form. (John Arbash Meinel, #295161)</li>
<li>Constructor parameters for NewPack (internal to pack repositories)
have changed incompatibly.</li>
<li><tt class="docutils literal"><span class="pre">Repository.abort_write_group</span></tt> now accepts an optional
<tt class="docutils literal"><span class="pre">suppress_errors</span></tt> flag. Repository implementations that override
<tt class="docutils literal"><span class="pre">abort_write_group</span></tt> will need to be updated to accept the new
argument. Subclasses that only override <tt class="docutils literal"><span class="pre">_abort_write_group</span></tt>
don’t need to change.</li>
<li>Transport implementations must provide copy_tree_to_transport. A default
implementation is provided for Transport subclasses.</li>
