<p>The sixth release in our 2.0 series addresses several user-inconvenience

<div class="section" id="id1">
<h3>Bug Fixes<a class="headerlink" href="#id1" 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">revert</span></tt> now only takes write lock on working tree, instead of on
both working tree and branch.
(Danny van Heumen, #498409)</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>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>
<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.

<ul class="simple">
<li>Avoid <tt class="docutils literal"><span class="pre">malloc(0)</span></tt> in <tt class="docutils literal"><span class="pre">patiencediff</span></tt>, which is non-portable.
(Martin Pool, #331095)</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>Cope with the lockdir <tt class="docutils literal"><span class="pre">held/info</span></tt> file being empty, which seems to
happen fairly often if the process is suddenly interrupted while taking
a lock.
(Martin Pool, #185103)</li>
<li>Give the warning about potentially slow cross-format fetches much
earlier on in the fetch operation. Don’t show this message during
upgrades, and show the correct format indication for remote
repositories.
(Martin Pool, #456077, #515356, #513157)</li>
<li>Handle renames correctly when there are files or directories that
differ only in case. (Chris Jones, Martin Pool, #368931)</li>
<li>If <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">push</span> <span class="pre">--create-prefix</span></tt> triggers an unexpected <tt class="docutils literal"><span class="pre">NoSuchFile</span></tt>
error, report that error rather than failing with an unhelpful
<tt class="docutils literal"><span class="pre">UnboundLocalError</span></tt>.
(Andrew Bennetts, #423563)</li>
<li>Running <tt class="docutils literal"><span class="pre">bzr</span></tt> command without any arguments now shows bzr
version number along with rest of the help text.
(Parth Malwankar, #369501)</li>
<li>Use osutils.O_NOINHERIT for some files on win32 to avoid PermissionDenied

<p>The fourth bugfix-only release in the 2.0 series contains more than a
dozen bugfixes relative to 2.0.3. The primary focus is on handling
interruptions and concurrent operations more cleanly, there is also a fair
improvement to <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">export</span></tt> when exporting a remote branch.</p>
<div class="section" id="id5">
<h3>Bug Fixes<a class="headerlink" href="#id5" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">annotate</span></tt> on another branch with <tt class="docutils literal"><span class="pre">-r</span> <span class="pre">branch:...</span></tt> no longer
fails with an <tt class="docutils literal"><span class="pre">ObjectNotLocked</span></tt> error. (Andrew Bennetts, #496590)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">export</span> <span class="pre">dir</span></tt> now requests all file content as a record stream,
rather than requsting the file content one file-at-a-time. This can make
exporting over the network significantly faster (54min => 9min in one
case). (John Arbash Meinel, #343218)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">serve</span></tt> no longer slowly leaks memory. The compiled
<tt class="docutils literal"><span class="pre">bzrlib.bencode.Encoder()</span></tt> class was using <tt class="docutils literal"><span class="pre">__del__</span></tt> to cleanup and
free resources, and it should have been using <tt class="docutils literal"><span class="pre">__dealloc__</span></tt>.
This will likely have an impact on any other process that is serving for
an extended period of time. (John Arbash Meinel, #494406)</li>
<li>Check for SIGINT (Ctrl-C) and other signals immediately if <tt class="docutils literal"><span class="pre">readdir</span></tt>
returns <tt class="docutils literal"><span class="pre">EINTR</span></tt> by calling <tt class="docutils literal"><span class="pre">PyErr_CheckSignals</span></tt>. This affected the
optional <tt class="docutils literal"><span class="pre">_readdir_pyx</span></tt> extension. (Andrew Bennetts, #495023)</li>
<li>Concurrent autopacks will no longer lose a newly created pack file.
There was a race condition, where if the reload happened at the right
time, the second packer would forget the name of the newly added pack
file. (John Arbash Meinel, Gareth White, #507566)</li>
<li>Give a clearer message if the lockdir disappears after being apparently
successfully taken. (Martin Pool, #498378)</li>
<li>Give a warning when fetching between repositories (local or remote) with
sufficiently different formats that the content will need to be
serialized (ie <tt class="docutils literal"><span class="pre">InterDifferingSerializer</span></tt> or <tt class="docutils literal"><span class="pre">inventory-deltas</span></tt>), so
the user has a clue that upgrading could make it faster.
(Martin Pool, #456077)</li>
<li>If we fail to open <tt class="docutils literal"><span class="pre">~/.bzr.log</span></tt> write a clear message to stderr rather
than using <tt class="docutils literal"><span class="pre">warning()</span></tt>. The log file is opened before logging is set
up, and it leads to very confusing: ‘no handlers for “bzr”’ messages for
users, rather than something nicer.
(John Arbash Meinel, Barry Warsaw, #503886)</li>
<li>Refuse to build with any Pyrex 0.9.4 release, as they have known bugs.
(Martin Pool, John Arbash Meinel, #449372)</li>
<li><tt class="docutils literal"><span class="pre">setup.py</span> <span class="pre">bdist_rpm</span></tt> now properly finds extra files needed for the
build. (there is still the distutils bug
<a class="reference external" href="http://bugs.python.org/issue644744">http://bugs.python.org/issue644744</a>) (Joe Julian, #175839)</li>
<li>The 2a format wasn’t properly restarting autopacks when something
changed underneath it (like another autopack). Now concurrent
autopackers will properly succeed. (John Arbash Meinel, #495000)</li>
<li><tt class="docutils literal"><span class="pre">TreeTransform</span></tt> can now handle when a delta says that the file id for
the tree root changes. Rather than trying to rename your working
directory, or failing early saying that you can’t have multiple
tree roots. This also fixes revert, update, and pull when the root id
changes. (John Arbash Meinel, #494269, #504390)</li>
<li><tt class="docutils literal"><span class="pre">_update_current_block</span></tt> no longer suppresses exceptions, so ^C at just
the right time will get propagated, rather than silently failing to move
the block pointer. (John Arbash Meinel, Gareth White, #495023)</li>

<li>Fixed <tt class="docutils literal"><span class="pre">ObjectNotLocked</span></tt> errors when doing some log and diff operations
on branches via a smart server. (Andrew Bennetts, #389413)</li>
<li>Handle things like <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">add</span> <span class="pre">foo</span></tt> and <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">rm</span> <span class="pre">foo</span></tt> when the tree is
at the root of a drive. <tt class="docutils literal"><span class="pre">osutils._cicp_canonical_relpath</span></tt> always
assumed that <tt class="docutils literal"><span class="pre">abspath()</span></tt> returned a path that did not have a trailing
<tt class="docutils literal"><span class="pre">/</span></tt>, but that is not true when working at the root of the filesystem.
(John Arbash Meinel, Jason Spashett, #322807)</li>
<li>Hide deprecation warnings for ‘final’ releases for python2.6.
(John Arbash Meinel, #440062)</li>
<li>Improve the time for <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">DIR</span></tt> for 2a format repositories.
We had been using the same code path as for <2a formats, which required
iterating over all objects in all revisions.
(John Arbash Meinel, #374730)</li>
<li>Make sure that we unlock the tree if we fail to create a TreeTransform
object when doing a merge, and there is limbo, or pending-deletions
directory. (Gary van der Merwe, #427773)</li>
<li>Occasional IndexError on renamed files have been fixed. Operations that
set a full inventory in the working tree will now go via the
apply_inventory_delta code path which is simpler and easier to
understand than dirstates set_state_from_inventory method. This may
have a small performance impact on operations built on _write_inventory,
but such operations are already doing full tree scans, so no radical
performance change should be observed. (Robert Collins, #403322)</li>
<li>Retrieving file text or mtime from a _PreviewTree has good performance when
there are many changes. (Aaron Bentley)</li>
<li>The CHK index pages now use an unlimited cache size. With a limited
cache and a large project, the random access of chk pages could cause us
to download the entire cix file many times.
(John Arbash Meinel, #402623)</li>
<li>When a file kind becomes unversionable after being added, a sensible
error will be shown instead of a traceback. (Robert Collins, #438569)</li>

<p>This release of Bazaar makes the 2a (previously ‘brisbane-core’) format
the default when new branches or repositories are created. This format is
substantially smaller and faster for many operations. Most of the work in
this release focuses on bug fixes and stabilization, covering both 2a and
previous formats. (See the Upgrade Guide for information on migrating
existing projects.)</p>
<p>This release also improves the documentation content and presentation,
including adding Windows HtmlHelp manuals.</p>
<p>The Bazaar team decided that 2.0 will be a long-term supported release,
with bugfix-only 2.0.x releases based on it, continuing for at least six
months or until the following stable release.</p>

<h3>Bug Fixes<a class="headerlink" href="#id14" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Bazaar’s native protocol code now correctly handles EINTR, which most
noticeably occurs if you break in to the debugger while connected to a
bzr+ssh server. You can now can continue from the debugger (by typing
‘c’) and the process continues. However, note that pressing C-in the
shell may still kill the SSH process, which is bug 162509, so you must
sent a signal to the bzr process specifically, for example by typing
<tt class="docutils literal"><span class="pre">kill</span> <span class="pre">-QUIT</span> <span class="pre">PID</span></tt> in another shell. (Martin Pool, #341535)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">check</span></tt> in pack-0.92, 1.6 and 1.9 format repositories will no
longer report incorrect errors about <tt class="docutils literal"><span class="pre">Missing</span> <span class="pre">inventory</span> <span class="pre">('TREE_ROOT',</span> <span class="pre">...)</span></tt>
(Robert Collins, #416732)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">info</span> <span class="pre">-v</span></tt> on a 2a format still claimed that it was a “Development
format” (John Arbash Meinel, #424392)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">stacked-branch</span></tt> shows the full log including
revisions that are in the fallback repository. (Regressed in 2.0rc1).
(John Arbash Meinel, #419241)</li>
<li>Clearer message when Bazaar runs out of memory, instead of a <tt class="docutils literal"><span class="pre">MemoryError</span></tt>
traceback. (Martin Pool, #109115)</li>
<li>Conversion to 2a will create a single pack for all the new revisions (as
long as it ran without interruption). This improves both <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">upgrade</span></tt>
and <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">pull</span></tt> or <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">merge</span></tt> from local branches in older formats.
The autopack logic that occurs every 100 revisions during local
conversions was not returning that pack’s identifier, which resulted in
the partial packs created during the conversion not being consolidated
at the end of the conversion process. (Robert Collins, #423818)</li>
<li>Fetches from 2a to 2a are now again requested in ‘groupcompress’ order.
Groups that are seen as ‘underutilized’ will be repacked on-the-fly.
This means that when the source is fully packed, there is minimal
overhead during the fetch, but if the source is poorly packed the result
is a fairly well packed repository (not as good as ‘bzr pack’ but
good-enough.) (Robert Collins, John Arbash Meinel, #402652)</li>
<li>Fix a potential segmentation fault when doing ‘log’ of a branch that had
ghosts in its mainline. (Evaluating None as a tuple is bad.)
(John Arbash Meinel, #419241)</li>
<li><tt class="docutils literal"><span class="pre">groupcompress</span></tt> sort order is now more stable, rather than relying on
<tt class="docutils literal"><span class="pre">topo_sort</span></tt> ordering. The implementation is now
<tt class="docutils literal"><span class="pre">KnownGraph.gc_sort</span></tt>. (John Arbash Meinel)</li>
<li>Local data conversion will generate correct deltas. This is a critical
bugfix vs 2.0rc1, and all 2.0rc1 users should upgrade to 2.0rc2 before
converting repositories. (Robert Collins, #422849)</li>
<li>Network streams now decode adjacent records of the same type into a
single stream, reducing layering churn. (Robert Collins)</li>
<li>Prevent some kinds of incomplete data from being committed to a 2a
repository, such as revisions without inventories, a missing chk_bytes
record for an inventory, or a missing text referenced by an inventory.

<h3>Compatibility Breaks<a class="headerlink" href="#id16" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>The default format for bzr is now <tt class="docutils literal"><span class="pre">2a</span></tt>. This format brings many
significant performance and size improvements. bzr can pull from
any existing repository into a <tt class="docutils literal"><span class="pre">2a</span></tt> one, but can only transfer
from <tt class="docutils literal"><span class="pre">2a</span></tt> into <tt class="docutils literal"><span class="pre">rich-root</span></tt> repositories. The Upgrade guide
has more information about this change. (Robert Collins)</li>

(Jason Spashett, #76616)</li>
<li>Fetches were being requested in ‘groupcompress’ order, but weren’t
recombining the groups. Thus they would ‘fragment’ to get the correct
order, but not ‘recombine’ to actually benefit from it. Until we get
recombining to work, switching to ‘unordered’ fetches avoids the
fragmentation. (John Arbash Meinel, #402645)</li>
<li>Fix a pycurl related test failure on karmic by recognizing an error

<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">branch</span></tt> of 2a repositories over HTTP is much faster. bzr now

(Martin Pool, #409137)</li>
<li>bzr can now (again) capture crash data through the apport library,
so that a single human-readable file can be attached to bug reports.
This can be disabled by using <tt class="docutils literal"><span class="pre">-Dno_apport</span></tt> on the command line, or by
putting <tt class="docutils literal"><span class="pre">no_apport</span></tt> into the <tt class="docutils literal"><span class="pre">debug_flags</span></tt> section of
<tt class="docutils literal"><span class="pre">bazaar.conf</span></tt>.

(Robert Collins, #305006)</li>
<li>Commit of specific files no longer prevents using the iter_changes
codepath. On 2a repositories, commit of specific files should now be as
fast, or slightly faster, than a full commit. (Robert Collins)</li>
<li>The internal core code that handles specific file operations like
<tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">st</span> <span class="pre">FILENAME</span></tt> or <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">commit</span> <span class="pre">FILENAME</span></tt> has been changed to
include the parent directories if they have altered, and when a
directory stops being a directory its children are always included. This
fixes a number of causes for <tt class="docutils literal"><span class="pre">InconsistentDelta</span></tt> errors, and permits
faster commit of specific paths. (Robert Collins, #347649)</li>
