<p>The third release in our 2.1 series addresses several user-inconvenience bugs
(and includes the fixes done in 2.0.6). None are critical, but upgrading is
recommended for all users on earlier 2.1 releases.</p>

<h3>Bug Fixes<a class="headerlink" href="#id9" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Additional merges after an unrelated branch has been merged with its
history no longer crash when deleted files are involved.
(Vincent Ladeuil, John Arbash Meinel, #375898)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">add</span> <span class="pre">SYMLINK/FILE</span></tt> now works properly when the symlink points to a
previously-unversioned directory within the tree: the directory is
marked versioned too.
(Martin Pool, #192859)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">commit</span> <span class="pre">SYMLINK</span></tt> now works, rather than trying to commit the
target of the symlink.
(Martin Pool, John Arbash Meinel, #128562)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">upgrade</span></tt> now creates the <tt class="docutils literal"><span class="pre">backup.bzr</span></tt> directory with the same
permissions as <tt class="docutils literal"><span class="pre">.bzr</span></tt> directory on a POSIX OS.
(Parth Malwankar, #262450)</li>
<li>Configuration files in <tt class="docutils literal"><span class="pre">${BZR_HOME}</span></tt> are now written in an atomic
way which should help avoid problems with concurrent writers.
(Vincent Ladeuil, #525571)</li>
<li>Don’t traceback trying to unversion children files of an already
unversioned directory. (Vincent Ladeuil, #494221)</li>
<li>Don’t traceback when a lockdir’s <tt class="docutils literal"><span class="pre">held/info</span></tt> file is corrupt (e.g.
contains only NUL bytes). Instead warn the user, and allow <tt class="docutils literal"><span class="pre">bzr</span>
<span class="pre">break-lock</span></tt> to remove it. (Andrew Bennetts, #619872)</li>
<li>Fix <tt class="docutils literal"><span class="pre">AttributeError</span> <span class="pre">on</span> <span class="pre">parent.children</span></tt> when adding a file under a
directory that was a symlink in the previous commit.
(Martin Pool, #192859)</li>
<li>Prevent <tt class="docutils literal"><span class="pre">CHKMap.apply_delta</span></tt> from generating non-canonical CHK maps,
which can result in “missing referenced chk root keys” errors when
fetching from repositories with affected revisions.
(Andrew Bennetts, #522637)</li>
<li>Raise ValueError instead of a string exception.
(John Arbash Meinel, #586926)</li>
<li>Reduce peak memory by one copy of compressed text.
(John Arbash Meinel, #566940)</li>
<li>Repositories accessed via a smart server now reject being stacked on a
repository in an incompatible format, as is the case when accessing them
via other methods. This was causing fetches from those repositories via
a smart server (e.g. using <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">branch</span></tt>) to receive invalid data.
(Andrew Bennetts, #562380)</li>
<li>Selftest with versions of subunit that support <tt class="docutils literal"><span class="pre">stopTestRun</span></tt> will no longer
error. This error was caused by 2.0 not being updated when upstream
python merged the end of run patch, which chose <tt class="docutils literal"><span class="pre">stopTestRun</span></tt> rather than
<tt class="docutils literal"><span class="pre">done</span></tt>. (Robert Collins, #571437)</li>

(Martin [gz], #254278)</li>
<li>When passing a file to <tt class="docutils literal"><span class="pre">UTF8DirReader</span></tt> make sure to close the current
directory file handle after the chdir fails. Otherwise when passing many
filenames into a command line <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">status</span></tt> we would leak descriptors.

terminal width as needed. This avoids the “Interrupted System Call”
problems that occur on POSIX with all currently released versions of
Python.
(Andrew Bennetts, #583941)</li>
<li>Fixed <tt class="docutils literal"><span class="pre">AssertionError</span></tt> when accessing smart servers running Bazaar
versions before 1.6.

<tt class="docutils literal"><span class="pre">bzrlib.osutils</span></tt>. Reduces the likelihood of “Interrupted System Call”

<li>Reduce peak memory by one copy of compressed text.
(John Arbash Meinel, #566940)</li>

<p>This release marks our second long-term-stable series. The Bazaar team
has decided that we will continue to make bugfix-only 2.0.x and 2.1.x
releases, along with 2.2 development releases.</p>
<p>This is a fairly incremental update, focusing on polish and bugfixing.
There are no changes for supported disk formats. Key updates include
reduced memory consumption for many operations, a new per-file merge
hook, ignore patterns can now include ‘!’ to exclude files, globbing
support for all commands on Windows, and support for addressing home
directories via <tt class="docutils literal"><span class="pre">bzr+ssh://host/~/</span></tt> syntax.</p>
<p>Users are encouraged to upgrade from the 2.0 stable series.</p>

<p>This is the first stable release candidate for Bazaar’s 2.1 series. From
this point onwards, the 2.1 series will be considered stable (as the 2.0
series) and only bugfixes are expected to be incorporated. The dozen or so
bugfixes in the 2.0.4 release are also included in this release (along
with more than 15 more bugfixes). Some of the interesting features are
support for per-file merge hooks, <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">unshelve</span> <span class="pre">--preview</span></tt>, support
for using ! in ignore files to exclude files from being ignored, a small
memory leak was squashed, and many <tt class="docutils literal"><span class="pre">ObjectNotLocked</span></tt> errors were fixed.
This looks to be a very good start for a new stable series.</p>

<h3>New Features<a class="headerlink" href="#id22" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Add bug information to log output when available.
(Neil Martinsen-Burrell, Guillermo Gonzalez, #251729)</li>
<li>Added <tt class="docutils literal"><span class="pre">merge_file_content</span></tt> hook point to <tt class="docutils literal"><span class="pre">Merger</span></tt>, allowing plugins
to register custom merge logic, e.g. to provide smarter merging for
particular files.</li>
<li>Bazaar now includes the <tt class="docutils literal"><span class="pre">news_merge</span></tt> plugin. It is disabled by
default, to enable it add a <tt class="docutils literal"><span class="pre">news_merge_files</span></tt> option to your
configuration. Consult <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">help</span> <span class="pre">news_merge</span></tt> for more information.
(Andrew Bennetts)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">branch</span></tt> now takes a <tt class="docutils literal"><span class="pre">--bind</span></tt> option. This lets you
branch and bind all in one command. (Ian Clatworthy)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">switch</span></tt> now takes a <tt class="docutils literal"><span class="pre">--revision</span></tt> option, to allow switching to
a specific revision of a branch. (Daniel Watkins, #183559)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">unshelve</span> <span class="pre">--preview</span></tt> can now be used to show how a patch on the
shelf would be applied to the working tree.
(Guilherme Salgado, #308122)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">update</span></tt> now takes a <tt class="docutils literal"><span class="pre">--revision</span></tt> argument. This lets you
change the revision of the working tree to any revision in the
ancestry of the current or master branch. (Matthieu Moy, Mark Hammond,
Martin Pool, #45719)</li>
<li><tt class="docutils literal"><span class="pre">-Dbytes</span></tt> can now be used to display the total number of bytes
transferred for the current command. This information is always logged
to <tt class="docutils literal"><span class="pre">.bzr.log</span></tt> for later inspection. (John Arbash Meinel)</li>
<li>New ignore patterns. Patterns prefixed with ‘!’ are exceptions to
ignore patterns and take precedence over regular ignores. Such
exceptions are used to specify files that should be versioned which
would otherwise be ignored. Patterns prefixed with ‘!!’ act as regular
ignore patterns, but have highest precedence, even over the ‘!’
exception patterns. (John Whitley, #428031)</li>
<li>The <tt class="docutils literal"><span class="pre">supress_warnings</span></tt> configuration option has been introduced to disable
various warnings (it currently only supports the <tt class="docutils literal"><span class="pre">format_deprecation</span></tt>
warning). The new option can be set in any of the following locations:
<tt class="docutils literal"><span class="pre">bazaar.conf</span></tt>, <tt class="docutils literal"><span class="pre">locations.conf</span></tt> and/or <tt class="docutils literal"><span class="pre">branch.conf</span></tt>.

<h3>Bug Fixes<a class="headerlink" href="#id23" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Always show a message if an OS error occurs while trying to run a
user-specified commit message editor.
(Martin Pool, #504842)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">diff</span></tt> will now use the epoch when it is unable to determine
the timestamp of a file, if the revision it was introduced in is a
ghost. (Jelmer Vernooij, #295611)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">switch</span> <span class="pre">-b</span></tt> can now create branches that are located using directory
services such as <tt class="docutils literal"><span class="pre">lp:</span></tt>, even when the branch name doesn’t contain a
‘/’. (Neil Martinsen-Burrell, #495263)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">unshelve</span></tt> has improved messages about what it is doing.
(Neil Martinsen-Burrell, #496917)</li>
<li>Concurrent autopacking is more resilient to already-renamed pack files.
If we find that a file we are about to obsolete is already obsoleted, we
do not try to rename it, and we leave the file in <tt class="docutils literal"><span class="pre">obsolete_packs</span></tt>.
The code is also fault tolerant if a file goes missing, assuming that
another process already removed the file.
(John Arbash Meinel, Gareth White, #507557)</li>
<li>Fix “Too many concurrent requests” in reconcile when network connection
fails. (Andrew Bennetts, #503878)</li>
<li>Fixed a side effect mutation of <tt class="docutils literal"><span class="pre">RemoteBzrDirFormat._network_name</span></tt>
that caused some tests to fail when run in a non-default order.
Probably no user impact. (Martin Pool, #504102)</li>

<li>FTP transports support Unicode paths by encoding/decoding them as utf8.
(Vincent Ladeuil, #472161)</li>
<li>Listen to the SIGWINCH signal to update the terminal width.
(Vincent Ladeuil, #316357)</li>
<li>Progress bars are now hidden when <tt class="docutils literal"><span class="pre">--quiet</span></tt> is given.
(Martin Pool, #320035)</li>
<li><tt class="docutils literal"><span class="pre">SilentUIFactory</span></tt> now supports <tt class="docutils literal"><span class="pre">make_output_stream</span></tt> and discards
whatever is written to it. This un-breaks some plugin tests that
depended on this behaviour.
(Martin Pool, #499757)</li>
<li>When operations update the working tree, all affected files should end
up with the same mtime. (eg. when versioning a generated file, if you
update the source and the generated file together, the generated file
should appear up-to-date.)

robust. (Andrew Bennetts)</li>
<li>All except a small number of storage formats are now hidden, making

<li>Attempts to open a shared repository as a branch (e.g. <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">branch</span>
<span class="pre">path/to/repo</span></tt>) will now include “location is a repository” as a hint in
the error message. (Brian de Alwis, Andrew Bennetts, #440952)</li>

<li>Many test features were renamed from <tt class="docutils literal"><span class="pre">FooFeature</span></tt> to <tt class="docutils literal"><span class="pre">foo_feature</span></tt>
to be consistent with instances being lower case and classes being
CamelCase. For the features that were more likely to be used, we added a
deprecation thunk, but not all. (John Arbash Meinel)</li>
<li>Merger classes (such as <tt class="docutils literal"><span class="pre">Merge3Merger</span></tt>) now expect a <tt class="docutils literal"><span class="pre">this_branch</span></tt>

<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzrlib.tests.permute_for_extension</span></tt> is a helper that simplifies

<tt class="docutils literal"><span class="pre">load_tests</span></tt>. (John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.tests.TestCase</span></tt> now subclasses <tt class="docutils literal"><span class="pre">testtools.testcase.TestCase</span></tt>.
This permits features in testtools such as getUniqueInteger and
getUniqueString to be used. Because of this, testtools version 0.9.2 or
newer is now a dependency to run bzr selftest. Running with versions of
testtools less than 0.9.2 will cause bzr to error while loading the test
suite. (Robert Collins)</li>
<li>Shell-like tests now support the command “mv” for moving files. The

tweaks. There has also been a significant number of tweaks to the runtime
documentation. 2.1.0b4 include everything from the 2.0.3 release.</p>

<p>This release was pushed up from its normal release cycle due to a
regression in python 2.4 compatibility in 2.1.0b2. Since this regression
was caught before 2.1.0b2 was officially announced, the full changelog
includes both 2.1.0b3 and 2.1.0b2 changes.</p>
<p>Highlights of 2.1.0b3 are: new globbing code for all commands on Windows,

<li>Improve “Binary files differ” hunk handling. (Aaron Bentley, #436325)</li>
<li>On Windows, do glob expansion at the command-line level (as is usually
done in bash, etc.) This means that <em>all</em> commands get glob expansion
(bzr status, bzr add, bzr mv, etc). It uses a custom command line
parser, which allows us to know if a given section was quoted. It means
you can now do <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">ignore</span> <span class="pre">"*.py"</span></tt>.
(John Arbash Meinel, #425510, #426410, #194450)</li>
<li>Sanitize commit messages that come in from the ‘-m’ flag. We translate
‘rn’ => ‘n’ and a plain ‘r’ => ‘n’. The storage layer doesn’t
allow those because XML store silently translate it anyway. (The parser
auto-translates rn => n in ways that are hard for us to catch.)</li>

<li>Using <tt class="docutils literal"><span class="pre">Repository.get_commit_builder().record_iter_changes()</span></tt> now
correctly sets <tt class="docutils literal"><span class="pre">self.inv_sha1</span></tt> to a sha1 string and

<tt class="docutils literal"><span class="pre">repo.add_revision</span></tt> ignores the supplied inventory sha1 and recomputes
the sha1 from the repo directly. (John Arbash Meinel)</li>
<li>Shelve command refuse to run if there is no real terminal.

<p>This is our second feature-filled release since 2.0, pushing us down the
path to a 2.1.0. Once again, all bugfixes in 2.0.2 are present in 2.1.0b2.</p>
<p>Key highlights in this release are: improved handling of
failures-during-cleanup for commit, fixing a long-standing bug with
<tt class="docutils literal"><span class="pre">bzr+http</span></tt> and shared repositories, all <tt class="docutils literal"><span class="pre">lp:</span></tt> URLs to be resolved
behind proxies, and a new StaticTuple datatype, allowing us to reduce
memory consumption (50%) and garbage collector overhead (40% faster) for
many operations.</p>
<ul class="simple">
<li>A new <tt class="docutils literal"><span class="pre">--concurrency</span></tt> option has been added as well as an associated
BZR_CONCURRENCY environment variable to specify the number of
processes that can be run concurrently when running <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">selftest</span></tt>. The
command-line option overrides the environment variable if both are
specified. If none is specified. the number of processes is obtained

<li><tt class="docutils literal"><span class="pre">bzr+http</span></tt> servers no longer give spurious jail break errors when
serving branches inside a shared repository. (Andrew Bennetts, #348308)</li>
<li>Errors during commit are handled more robustly so that knock-on errors
are less likely to occur, and will not obscure the original error if
they do occur. This fixes some causes of <tt class="docutils literal"><span class="pre">TooManyConcurrentRequests</span></tt>

<li>Added <tt class="docutils literal"><span class="pre">bzrlib._simple_set_pyx</span></tt>. This is a hybrid between a Set and a
Dict (it only holds keys, but you can lookup the object located at a
given key). It has significantly reduced memory consumption versus the
builtin objects (1/2 the size of Set, 1/3rd the size of Dict). This is
used as the interning structure for StaticTuple objects.
(John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib._static_tuple_c.StaticTuple</span></tt> is now available and used by
the btree index parser and the chk map parser. This class functions
similarly to <tt class="docutils literal"><span class="pre">tuple</span></tt> objects. However, it can only point to a limited
collection of types. (Currently StaticTuple, str, unicode, None, bool,
int, long, float, but not subclasses). This allows us to remove it from
the garbage collector (it cannot be in a cycle), it also allows us to
intern the objects. In testing, this can reduce peak memory by 20-40%,
and significantly improve performance by removing objects from being
inspected by the garbage collector. (John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">GroupCompressBlock._ensure_content()</span></tt> will now release the
<tt class="docutils literal"><span class="pre">zlib.decompressobj()</span></tt> when the first request is for all of the
content. (Previously it would only be released if you made a request for
part of the content, and then all of it later.) This turns out to be a
significant memory savings, as a <tt class="docutils literal"><span class="pre">zstream</span></tt> carries around approx 260kB
of internal state and buffers. (For branching bzr.dev this drops peak
memory from 382MB => 345MB.) (John Arbash Meinel)</li>
<li>When streaming content between <tt class="docutils literal"><span class="pre">2a</span></tt> format repositories, we now clear
caches from earlier versioned files. (So ‘revisions’ is cleared when we
start reading ‘inventories’, etc.) This can have a significant impact on
peak memory for initial copies (~200MB). (John Arbash Meinel)</li>

<p>This is the first development release in the new split “stable” and
“development” series. As such, the release is a snapshot of bzr.dev
without creating a release candidate first. This release includes a
fair amount of internal changes, with deprecated code being removed,
and several new feature developments. People looking for a stable code
base with only bugfixes should focus on the 2.0.1 release. All bugfixes
present in 2.0.1 are present in 2.1.0b1.</p>
<p>Highlights include support for <tt class="docutils literal"><span class="pre">bzr+ssh://host/~/homedir</span></tt> style URLs,
finer control over the plugin search path via extended BZR_PLUGIN_PATH
syntax, visible warnings when extension modules fail to load, and improved

decorator, <tt class="docutils literal"><span class="pre">only_raises</span></tt>. This fixes many causes of
<tt class="docutils literal"><span class="pre">TooManyConcurrentRequests</span></tt> and similar errors.

<ul class="simple">
<li>Describe the new shell-like test feature. (Vincent Ladeuil)</li>

<h3>API Changes<a class="headerlink" href="#id51" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzrlib.user_encoding</span></tt> has been removed; use
<tt class="docutils literal"><span class="pre">bzrlib.osutils.get_user_encoding</span></tt> instead. (Martin Pool)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.tests</span></tt> now uses <tt class="docutils literal"><span class="pre">stopTestRun</span></tt> for its <tt class="docutils literal"><span class="pre">TestResult</span></tt>
subclasses - the same as python’s unittest module. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">diff._get_trees_to_diff</span></tt> has been renamed to
<tt class="docutils literal"><span class="pre">diff.get_trees_and_branches_to_diff</span></tt>. It is now a public API, and it
returns the old and new branches. (Gary van der Merwe)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.trace.log_error</span></tt>, <tt class="docutils literal"><span class="pre">error</span></tt> and <tt class="docutils literal"><span class="pre">info</span></tt> have been deprecated.
(Martin Pool)</li>
<li><tt class="docutils literal"><span class="pre">MutableTree.has_changes()</span></tt> does not require a tree parameter anymore. It
now defaults to comparing to the basis tree. It now checks for pending
merges too. <tt class="docutils literal"><span class="pre">Merger.check_basis</span></tt> has been deprecated and replaced by the
corresponding has_changes() calls. <tt class="docutils literal"><span class="pre">Merge.compare_basis</span></tt>,
<tt class="docutils literal"><span class="pre">Merger.file_revisions</span></tt> and <tt class="docutils literal"><span class="pre">Merger.ensure_revision_trees</span></tt> have also
been deprecated.
(Vincent Ladeuil, #440631)</li>
<li><tt class="docutils literal"><span class="pre">ProgressTask.note</span></tt> is deprecated.
(Martin Pool)</li>
</ul>

<h3>Internals<a class="headerlink" href="#id52" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Added <tt class="docutils literal"><span class="pre">-Drelock</span></tt> debug flag. It will <tt class="docutils literal"><span class="pre">note</span></tt> a message every time a
repository or branch object is unlocked then relocked the same way.
(Andrew Bennetts)</li>
<li><tt class="docutils literal"><span class="pre">BTreeLeafParser.extract_key</span></tt> has been tweaked slightly to reduce
mallocs while parsing the index (approx 3=>1 mallocs per key read).
This results in a 10% speedup while reading an index.
(John Arbash Meinel)</li>
<li>The <tt class="docutils literal"><span class="pre">bzrlib.lsprof</span></tt> module has a new class <tt class="docutils literal"><span class="pre">BzrProfiler</span></tt> which makes
profiling in some situations like callbacks and generators easier.
(Robert Collins)</li>
</ul>
</div>
<div class="section" id="id53">
<h3>Testing<a class="headerlink" href="#id53" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Passing <tt class="docutils literal"><span class="pre">--lsprof-tests</span> <span class="pre">-v</span></tt> to bzr selftest will cause lsprof output to
be output for every test. Note that this is very verbose! (Robert Collins)</li>
<li>Setting <tt class="docutils literal"><span class="pre">BZR_TEST_PDB=1</span></tt> when running selftest will cause a pdb
post_mortem to be triggered when a test failure occurs. (Robert Collins)</li>
<li>Shell-like tests can now be written. Code in <tt class="docutils literal"><span class="pre">bzrlib/tests/script.py</span></tt> ,
documentation in <tt class="docutils literal"><span class="pre">developers/testing.txt</span></tt> for details.
(Vincent Ladeuil)</li>
<li>Some tests could end up with the same id, that was dormant for
a long time.
(Vincent Ladeuil, #442980)</li>
<li>Stop showing the number of tests due to missing features in the test
progress bar. (Martin Pool)</li>
<li>Test parameterisation now does a shallow copy, not a deep copy of the test
to be parameterised. This is not expected to break external use of test
parameterisation, and is substantially faster. (Robert Collins)</li>
<li>Tests that try to open a bzr dir on an arbitrary transport will now
fail unless they have explicitly permitted the transport via
<tt class="docutils literal"><span class="pre">self.permit_url</span></tt>. The standard test factories such as <tt class="docutils literal"><span class="pre">self.get_url</span></tt>
will permit the URLs they provide automatically, so only exceptional
tests should need to do this. (Robert Collins)</li>
<li>The break-in test no longer cares about clean shutdown of the child,
instead it is happy if the debugger starts up. (Robert Collins)</li>
<li>The full test suite is expected to pass when the C extensions are not
present. (Vincent Ladeuil, #430749)</li>
