<h3>Improvements<a class="headerlink" href="#improvements" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Knit files now wait to create their contents until the first data is
added. The old code used to create an empty .knit and a .kndx with just
the header. However, this caused a lot of extra round trips over SFTP.
This can change the time for <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">push</span></tt> to create a new remote branch
from 160s down to 100s. This also affects <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">commit</span></tt> performance when
adding new files, <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">commit</span></tt> on a new kernel-like tree drops from 50s
down to 40s (John Arbash Meinel, #44692)</li>
<li>When an entire subtree has been deleted, commit will now report that
just the top of the subtree has been deleted, rather than reporting
all the individual items. (Robert Collins)</li>
<li>Commit performs one less XML parse. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">checkout</span></tt> now operates on readonly branches as well
as readwrite branches. This fixes bug #39542. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">bind</span></tt> no longer synchronises history with the master branch.
Binding should be followed by an update or push to synchronise the
two branches. This is closely related to the fix for bug #39542.
(Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.lazy_import.lazy_import</span></tt> function to create on-demand
objects. This allows all imports to stay at the global scope, but
modules will not actually be imported if they are not used.
(John Arbash Meinel)</li>
<li>Support <tt class="docutils literal"><span class="pre">bzr://</span></tt> and <tt class="docutils literal"><span class="pre">bzr+ssh://</span></tt> URLS to work with the new RPC-based
transport which will be used with the upcoming high-performance smart
server. The new command <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">serve</span></tt> will invoke bzr in server mode,
which processes these requests. (Andrew Bennetts, Robert Collins, Martin
Pool)</li>
<li>New command <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">version-info</span></tt> which can be used to get a summary
of the current state of the tree. This is especially useful as part
of a build commands. See <tt class="docutils literal"><span class="pre">doc/version_info.txt</span></tt> for more information
(John Arbash Meinel)</li>

<h3>Bug Fixes<a class="headerlink" href="#id1" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">'bzr</span> <span class="pre">inventory</span> <span class="pre">[FILE...]'</span></tt> allows restricting the file list to a
specific set of files. (John Arbash Meinel, #3631)</li>
<li>Don’t abort when annotating empty files (John Arbash Meinel, #56814)</li>
<li>Add <tt class="docutils literal"><span class="pre">Stanza.to_unicode()</span></tt> which can be passed to another Stanza
when nesting stanzas. Also, add <tt class="docutils literal"><span class="pre">read_stanza_unicode</span></tt> to handle when
reading a nested Stanza. (John Arbash Meinel)</li>
<li>Transform._set_mode() needs to stat the right file.
(John Arbash Meinel, #56549)</li>
<li>Raise WeaveFormatError rather than StopIteration when trying to read
an empty Weave file. (John Arbash Meinel, #46871)</li>
<li>Don’t access e.code for generic URLErrors, only HTTPErrors have .code.
(Vincent Ladeuil, #59835)</li>
<li>Handle boundary=”” lines properly to allow access through a Squid proxy.
(John Arbash Meinel, #57723)</li>
<li>revert now removes newly-added directories (Aaron Bentley, #54172)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">upgrade</span> <span class="pre">sftp://</span></tt> shouldn’t fail to upgrade v6 branches if there
isn’t a working tree. (David Allouche, #40679)</li>
<li>Give nicer error messages when a user supplies an invalid –revision
parameter. (John Arbash Meinel, #55420)</li>
<li>Handle when LANG is not recognized by python. Emit a warning, but
just revert to using ‘ascii’. (John Arbash Meinel, #35392)</li>
<li>Don’t use <tt class="docutils literal"><span class="pre">preexec_fn</span></tt> on win32, as it is not supported by subprocess.
(John Arbash Meinel)</li>
<li>Skip specific tests when the dependencies aren’t met. This includes
some <tt class="docutils literal"><span class="pre">setup.py</span></tt> tests when <tt class="docutils literal"><span class="pre">python-dev</span></tt> is not available, and
some tests that depend on paramiko. (John Arbash Meinel, Mattheiu Moy)</li>
<li>Fallback to Paramiko properly, if no <tt class="docutils literal"><span class="pre">ssh</span></tt> executable exists on
the system. (Andrew Bennetts, John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">Branch.bind(other_branch)</span></tt> no longer takes a write lock on the
other branch, and will not push or pull between the two branches.
API users will need to perform a push or pull or update operation if they
require branch synchronisation to take place. (Robert Collins, #43744)</li>
<li>When creating a tarball or zipfile export, export unicode names as utf-8
paths. This may not work perfectly on all platforms, but has the best
chance of working in the common case. (John Arbash Meinel, #56815)</li>
<li>When committing, only files that exist in working tree or basis tree
may be specified (Aaron Bentley, #50793)</li>

<li>Fixes to run on Python 2.5 (Brian M. Carlson, Martin Pool, Marien Zwart)</li>
</ul>
</div>
<div class="section" id="internals">
<h3>Internals<a class="headerlink" href="#internals" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>TestCaseInTempDir now creates a separate directory for HOME, rather
than having HOME set to the same location as the working directory.
(John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">run_bzr_subprocess()</span></tt> can take an optional <tt class="docutils literal"><span class="pre">env_changes={}</span></tt> parameter,
which will update os.environ inside the spawned child. It also can
take a <tt class="docutils literal"><span class="pre">universal_newlines=True</span></tt>, which helps when checking the output
of the command. (John Arbash Meinel)</li>
<li>Refactor SFTP vendors to allow easier re-use when SSH is used.
(Andrew Bennetts)</li>
<li><tt class="docutils literal"><span class="pre">Transport.list_dir()</span></tt> and <tt class="docutils literal"><span class="pre">Transport.iter_files_recursive()</span></tt> should always
return urlescaped paths. This is now tested (there were bugs in a few
of the transports) (Andrew Bennetts, David Allouche, John Arbash Meinel)</li>
<li>New utility function <tt class="docutils literal"><span class="pre">symbol_versioning.deprecation_string</span></tt>. Returns the
formatted string for a callable, deprecation format pair. (Robert Collins)</li>
<li>New TestCase helper applyDeprecated. This allows you to call a callable
which is deprecated without it spewing to the screen, just by supplying
the deprecation format string issued for it. (Robert Collins)</li>
<li>Transport.append and Transport.put have been deprecated in favor of
<tt class="docutils literal"><span class="pre">.append_bytes</span></tt>, <tt class="docutils literal"><span class="pre">.append_file</span></tt>, <tt class="docutils literal"><span class="pre">.put_bytes</span></tt>, and
<tt class="docutils literal"><span class="pre">.put_file</span></tt>. This removes the ambiguity in what type of object the
functions take. <tt class="docutils literal"><span class="pre">Transport.non_atomic_put_{bytes,file}</span></tt> has also
been added. Which works similarly to <tt class="docutils literal"><span class="pre">Transport.append()</span></tt> except for
SFTP, it doesn’t have a round trip when opening the file. Also, it
provides functionality for creating a parent directory when trying
to create a file, rather than raise NoSuchFile and forcing the
caller to repeat their request.
(John Arbash Meinel)</li>
<li>WorkingTree has a new api <tt class="docutils literal"><span class="pre">unversion</span></tt> which allow the unversioning of
entries by their file id. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">WorkingTree.pending_merges</span></tt> is deprecated. Please use the
<tt class="docutils literal"><span class="pre">get_parent_ids</span></tt> (introduced in 0.10) method instead. (Robert Collins)</li>
<li>WorkingTree has a new <tt class="docutils literal"><span class="pre">lock_tree_write</span></tt> method which locks the branch for
read rather than write. This is appropriate for actions which only need
the branch data for reference rather than mutation. A new decorator
<tt class="docutils literal"><span class="pre">needs_tree_write_lock</span></tt> is provided in the workingtree module. Like the
<tt class="docutils literal"><span class="pre">needs_read_lock</span></tt> and <tt class="docutils literal"><span class="pre">needs_write_lock</span></tt> decorators this allows static
declaration of the locking requirements of a function to ensure that
a lock is taken out for casual scripts. (Robert Collins, #54107)</li>
<li>All WorkingTree methods which write to the tree, but not to the branch
have been converted to use <tt class="docutils literal"><span class="pre">needs_tree_write_lock</span></tt> rather than
<tt class="docutils literal"><span class="pre">needs_write_lock</span></tt>. Also converted is the revert, conflicts and tree
transform modules. This provides a modest performance improvement on
metadir style trees, due to the reduce lock-acquisition, and a more
significant performance improvement on lightweight checkouts from
remote branches, where trivial operations used to pay a significant
penalty. It also provides the basis for allowing readonly checkouts.
(Robert Collins)</li>
<li>Special case importing the standard library ‘copy’ module. This shaves
off 40ms of startup time, while retaining compatibility. See:
<tt class="docutils literal"><span class="pre">bzrlib/inspect_for_copy.py</span></tt> for more details. (John Arbash Meinel)</li>
<li>WorkingTree has a new parent class MutableTree which represents the
specialisations of Tree which are able to be altered. (Robert Collins)</li>
<li>New methods mkdir and <tt class="docutils literal"><span class="pre">put_file_bytes_non_atomic</span></tt> on MutableTree that
mutate the tree and its contents. (Robert Collins)</li>
<li>Transport behaviour at the root of the URL is now defined and tested.
(Andrew Bennetts, Robert Collins)</li>

<div class="section" id="testing">
<h3>Testing<a class="headerlink" href="#testing" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>New test helper classs MemoryTree. This is typically accessed via
<tt class="docutils literal"><span class="pre">self.make_branch_and_memory_tree()</span></tt> in test cases. (Robert Collins)</li>
<li>Add <tt class="docutils literal"><span class="pre">start_bzr_subprocess</span></tt> and <tt class="docutils literal"><span class="pre">stop_bzr_subprocess</span></tt> to allow test
code to continue running concurrently with a subprocess of bzr.
(Andrew Bennetts, Robert Collins)</li>
<li>Add a new method <tt class="docutils literal"><span class="pre">Transport.get_smart_client()</span></tt>. This is provided to
allow upgrades to a richer interface than the VFS one provided by
Transport. (Andrew Bennetts, Martin Pool)</li>
