<h2>Compatibility Breaks</h2>
<ul class="simple">
<li>bzr no longer autodetects nested trees as 'tree-references'. They
must now be explicitly added tree references. At the commandline, use
join --reference instead of add. (Aaron Bentley)</li>
</ul>

<div class="section" id="new-features">
<h2>New Features</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">shelve</span></tt> can now apply changes without storing anything on the
shelf, via the new --destroy option. (Aaron Bentley)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">send</span></tt> now accepts --body to specify an initial message body.
(Aaron bentley)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">xxx</span> <span class="pre">--usage</span></tt> where xxx is a command now shows a usage
message and the options without the descriptive help sections
(like Description and Examples). A message is also given
explaining how to see the complete help, i.e. <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">help</span> <span class="pre">xxx</span></tt>.

</div>
<div class="section" id="improvements">
<h2>Improvements</h2>
<ul class="simple">
<li>Branching from a stacked branch using <tt class="docutils literal"><span class="pre">bzr*://</span></tt> will now stream
the data when the target repository does not need topological
ordering, reducing round trips and network overhead. This uses the
existing smart server methods added in 1.13, so will work on any
1.13 or newer server. (Robert Collins, Andrew Bennetts)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">ignore</span></tt> gives a more informative message when existing
version controlled files match the ignore pattern. (Neil
Martinsen-Burrell, #248895)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">send</span></tt> is faster on repositories with deep histories.
(Ian Clatworthy)</li>
<li>Progress bars now show the rate of network activity for
<tt class="docutils literal"><span class="pre">bzr+ssh://</span></tt> and <tt class="docutils literal"><span class="pre">bzr://</span></tt> connections. (Andrew Bennetts)</li>
<li>Streaming push can be done to older repository formats. This is
implemented using a new <tt class="docutils literal"><span class="pre">Repository.insert_stream_locked</span></tt> RPC.
(Andrew Bennetts, Robert Collins)</li>
<li>Tildes are no longer escaped. No more %7Euser/project/branch!
(Jonathan Lange)</li>
</ul>
</div>
<div class="section" id="bug-fixes">
<h2>Bug Fixes</h2>
<ul class="simple">
<li>Authentication plugins now receive all the parameters from the request
itself (aka host, port, realm, path, etc). Previously, only the
authentication section name, username and encoded password were
provided. (Jean-Francois Roy)</li>
<li>Fix "is not a stackable format" error when pushing a
stackable-format branch with an unstackable-format repository to a
destination with a default stacking policy. (Andrew Bennetts)</li>
<li>Fixed incorrect "Source format does not support stacking" warning
when pushing to a smart server. (Andrew Bennetts, #334114)</li>
<li>It is no longer possible to fetch between repositories while the
target repository is in a write group. This prevents race conditions
that prevent the use of RPC's to perform fetch, and thus allows
optimising more operations. (Robert Collins, Andrew Bennetts)</li>
<li><tt class="docutils literal"><span class="pre">merge</span> <span class="pre">--force</span></tt> works again. (Robert Collins, #342105)</li>
<li>The GNU Changelog formatter is slightly improved in the case where
the delta is empty, and now correctly claims not to support tags.
(Andrea Bolognani)</li>
<li>Shelve can now shelve changes to a symlink target.
(James Westby, #341558)</li>
</ul>

<div class="section" id="documentation">
<h2>Documentation</h2>
<ul class="simple">
<li>New topic <cite>bzr help debug-flags</cite>. (Martin Pool)</li>
<li>The generated manpage now explicitly lists aliases as commands.
(James Westby, #336998)</li>
</ul>
</div>
<div class="section" id="api-changes">
<h2>API Changes</h2>
<ul class="simple">
<li>New sort order for <tt class="docutils literal"><span class="pre">get_record_stream</span></tt> <tt class="docutils literal"><span class="pre">groupcompress</span></tt> which
sorts optimally for use with groupcompress compressors. (John Arbash
Meinel, Robert Collins)</li>
<li>The <tt class="docutils literal"><span class="pre">get_credentials</span></tt> and <tt class="docutils literal"><span class="pre">set_credentials</span></tt> methods of
<tt class="docutils literal"><span class="pre">AuthenticationConfig</span></tt> now accept an optional realm argument.
(Jean-Francois Roy)</li>
<li>The <tt class="docutils literal"><span class="pre">pb</span></tt> argument to <tt class="docutils literal"><span class="pre">fetch()</span></tt> is deprecated.
(Martin Pool)</li>
</ul>
</div>
<div class="section" id="testing">
<h2>Testing</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzrlib.tests.TestCase</span></tt> now fails the test if its own <tt class="docutils literal"><span class="pre">setUp</span></tt>
and <tt class="docutils literal"><span class="pre">tearDown</span></tt> weren't called. This catches faulty tests that
forget to upcall when overriding <tt class="docutils literal"><span class="pre">setUp</span></tt> and <tt class="docutils literal"><span class="pre">tearDown</span></tt>. Those
faulty tests were not properly isolated.
(Andrew Bennetts, Robert Collins)</li>
</ul>
</div>
<div class="section" id="internals">
<h2>Internals</h2>
<ul class="simple">
<li>New <tt class="docutils literal"><span class="pre">assertLength</span></tt> method based on one Martin has squirreled away
somewhere. (Robert Collins, Martin Pool)</li>
<li>New repository method <tt class="docutils literal"><span class="pre">refresh_data</span></tt> to cause any repository to
make visible data inserted into the repository by a smart server
fetch operation. (Robert Collins, Andrew Bennetts)</li>
<li>Removed <tt class="docutils literal"><span class="pre">InterRemoteToOther</span></tt>, <tt class="docutils literal"><span class="pre">InterOtherToRemote</span></tt> and
<tt class="docutils literal"><span class="pre">InterPackToRemotePack</span></tt> classes, as they are now unnecessary.
(Andrew Bennetts)</li>
<li><tt class="docutils literal"><span class="pre">_walk_to_common_revisions</span></tt> will now batch up at least 50
revisions before calling <tt class="docutils literal"><span class="pre">get_parent_map</span></tt> on the target,
regardless of <tt class="docutils literal"><span class="pre">InterRepository</span></tt>.

<p>This release includes bug fixes and a few performance and feature improvements.
GNU Changelog output can now be produced by <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">--log-format</span> <span class="pre">gnu-changelog</span></tt>.
Debug flags can now be set in <tt class="docutils literal"><span class="pre">~/.bazaar/bazaar.conf</span></tt>. Lightweight checkouts
and stacked branches should both be much faster over remote connections.</p>

<h2>Changes From RC1 to Final</h2>
<ul class="simple">
<li>Fix "is not a stackable format" error when pushing a
stackable-format branch with an unstackable-format repository to a
destination with a default stacking policy. (Andrew Bennetts)</li>
<li>Progress bars now show the rate of network activity for
<tt class="docutils literal"><span class="pre">bzr+ssh://</span></tt> and <tt class="docutils literal"><span class="pre">bzr://</span></tt> connections. (Andrew Bennetts)</li>
</ul>
</div>
<div class="section" id="id1">
<h2>Compatibility Breaks</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">--line</span></tt> now indicates which revisions are merges with
<cite>[merge]</cite> after the date. Scripts which parse the output of this
command may need to be adjusted.
(Neil Martinsen-Burrell)</li>
</ul>
</div>
<div class="section" id="id2">
<h2>New Features</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">reconfigure</span></tt> now supports --with-trees and --with-no-trees
options to change the default tree-creation policy of shared
repositories. (Matthew Fuller, Marius Kruger, #145033)</li>
<li>Debug flags can now be set in <tt class="docutils literal"><span class="pre">~/.bazaar/bazaar.conf</span></tt>.
(Martin Pool)</li>
<li>Filtered views provide a mask over the tree so that users can focus
on a subset of a tree when doing their work. See <tt class="docutils literal"><span class="pre">Filtered</span> <span class="pre">views</span></tt>
in chapter 7 of the User Guide and <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">help</span> <span class="pre">view</span></tt> for details.
(Ian Clatworthy)</li>
<li>GNU Changelog output can now be produced by <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">--log-format</span>
<span class="pre">gnu-changelog</span></tt>. (Andrea Bolognani, Martin Pool)</li>
<li>The <tt class="docutils literal"><span class="pre">-Dmemory</span></tt> flag now gives memory information on Windows.
(John Arbash Meinel)</li>
<li>Multiple authors for a commit can now be recorded by using the "--author"
option multiple times. (James Westby, #185772)</li>
<li>New clean-tree command, from bzrtools. (Aaron Bentley, Jelmer Vernoij)</li>
<li>New command <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">launchpad-open</span></tt> opens a Launchpad web page for that
branch in your web browser, as long as the branch is on Launchpad at all.
(Jonathan Lange)</li>
<li>New API for getting bugs fixed by a revision: Revision.iter_bugs().
(Jonathan Lange)</li>

<h2>Improvements</h2>
<ul class="simple">
<li>All bzr <tt class="docutils literal"><span class="pre">Hooks</span></tt> classes are now registered in
<tt class="docutils literal"><span class="pre">bzrlib.hooks.known_hooks</span></tt>. This removes the separate list from
<tt class="docutils literal"><span class="pre">bzrlib.tests</span></tt> and ensures that all hooks registered there are
correctly isolated by the test suite (previously
<tt class="docutils literal"><span class="pre">MutableTreeHooks</span></tt> were not being isolated correctly). Further,
documentation for hooks is now dynamically generated from the
present HookPoints. <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">hooks</span></tt> will now also report on all the
hooks present in the <tt class="docutils literal"><span class="pre">bzrlib.hooks.known_hooks</span></tt> registry.
(Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">add</span></tt> no longer prints <tt class="docutils literal"><span class="pre">add</span> <span class="pre">completed</span></tt> on success. Failure
still prints an error message. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">branch</span></tt> now has a <tt class="docutils literal"><span class="pre">--no-tree</span></tt> option which turns off the
generation of a working tree in the new branch.
(Daniel Watkins, John Klinger, #273993)</li>
<li>Bazaar will now point out <tt class="docutils literal"><span class="pre">bzr+ssh://</span></tt> to the user when they
use <a class="reference external" href="ssh://">ssh://</a>. (Jelmer Vernooij, #330535)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">-v</span> <span class="pre">info</span></tt> now omits the number of committers branch statistic,
making it many times faster for large projects. To include that
statistic in the output, use <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">-vv</span> <span class="pre">info</span></tt>.
(Ian Clatworthy)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">push</span></tt> to a <tt class="docutils literal"><span class="pre">bzr</span></tt> url (<tt class="docutils literal"><span class="pre">bzr://</span></tt>, <tt class="docutils literal"><span class="pre">bzr+ssh://</span></tt> etc) will
stream if the server is version 1.13 or greater, reducing roundtrips
significantly. (Andrew Bennetts, Robert Collins)</li>
<li>Lightweight Checkouts and Stacked Branches should both be much
faster over remote connections. Building the working tree now
batches up requests into approx 5MB requests, rather than a separate
request for each file. (John Arbash Meinel)</li>
<li>Support for GSSAPI authentication when using HTTP or HTTPS.
(Jelmer Vernooij)</li>
<li>The <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">shelve</span></tt> prompt now includes a '?' help option to explain the
short options better. (Daniel Watkins, #327429)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">lp-open</span></tt> now falls back to the push location if it cannot find a
public location. (Jonathan Lange, #332372)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">lp-open</span></tt> will try to find the Launchpad URL for the location
passed on the command line. This makes <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">lp-open</span> <span class="pre">lp:foo</span></tt> work as
expected. (Jonathan Lange, #332705)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">send</span></tt> now supports MH-E via <tt class="docutils literal"><span class="pre">emacsclient</span></tt>. (Eric Gillespie)</li>
</ul>

<div class="section" id="id4">
<h2>Bug Fixes</h2>
<ul class="simple">
<li>Bazaar now gives a better message including the filename if it's
unable to read a file in the working directory, for example because
of a permission error. (Martin Pool, #338653)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">cat</span> <span class="pre">-r<old></span> <span class="pre"><path></span></tt> doesn't traceback anymore when <path> has a
file id in the working tree different from the one in revision <old>.
(Vincent Ladeuil, #341517, #253806)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">send</span></tt> help is more specific about how to apply merge
directives. (Neil Martinsen-Burrell, #253470)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">missing</span></tt> now uses <tt class="docutils literal"><span class="pre">Repository.get_revision_delta()</span></tt> rather
than fetching trees and determining a delta itself. (Jelmer
Vernooij, #315048)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">push</span></tt> to a smart server no longer causes "Revision
{set([('null:',)])} not present ..." errors when the branch has
multiple root revisions. (Andrew Bennetts, #317654)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">shelve</span></tt> now properly handle patches with no terminating newline.
(Benoît PIERRE, #303569)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">unshelve</span></tt> gives a more palatable error if passed a non-integer
shelf id. (Daniel Watkins)</li>
<li>Export now handles files that are not present in the tree.
(James Westby, #174539)</li>
<li>Fixed incorrect "Source format does not support stacking" warning
when pushing to a smart server. (Andrew Bennetts, #334114)</li>
<li>Fixed "sprout() got an unexpected keyword argument 'source_branch'"
error branching from old repositories.
(Martin Pool, #321695)</li>
<li>Make <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">push</span> <span class="pre">--quiet</span> <span class="pre"><non-local</span> <span class="pre">location></span></tt> less chatty.
(Kent Gibson, #221461)</li>
<li>Many Branch hooks would not fire with <tt class="docutils literal"><span class="pre">bzr://</span></tt> and <tt class="docutils literal"><span class="pre">bzr+ssh://</span></tt>
branches, and this was not noticed due to a bug in the test logic
for branches. This is now fixed and a test added to prevent it
reoccuring. (Robert Collins, Andrew Bennetts)</li>
<li>Restore the progress bar on Windows. We were disabling it when TERM
wasn't set, but Windows doesn't set TERM. (Alexander Belchenko)</li>
<li><tt class="docutils literal"><span class="pre">setup.py</span> <span class="pre">build_ext</span></tt> now gives a proper error when an extension
fails to build. (John Arbash Meinel)</li>
<li>Symlinks to non ascii file names are now supported.
(Robert Collins, Vincent Ladeuil, #339055, #272444)</li>
<li>Under rare circumstances (aka nobody reported a bug about it), the ftp
transport could revert to ascii mode. It now stays in binary mode except
when needed.
(Vincent Ladeuil)</li>
<li>Unshelve does not generate warnings about progress bars.
(Aaron Bentley, #328148)</li>
<li>shelve cleans up properly when unversioned files are specified.
(Benoît Pierre, Aaron Bentley)</li>

<div class="section" id="id5">
<h2>Documentation</h2>
<ul class="simple">
<li>Added <tt class="docutils literal"><span class="pre">Organizing</span> <span class="pre">your</span> <span class="pre">workspace</span></tt> to the User Guide appendices,
summarizing some common ways of organizing trees, branches and
repositories and the processes/workflows implied/enabled by each.
(Ian Clatworthy)</li>
<li>Hooks can now be self documenting. <tt class="docutils literal"><span class="pre">bzrlib.hooks.Hooks.create_hook</span></tt>
is the entry point for this feature. (Robert Collins)</li>
<li>The documentation for <tt class="docutils literal"><span class="pre">shelve</span></tt> and <tt class="docutils literal"><span class="pre">unshelve</span></tt> has been clarified.
(Daniel Watkins, #327421, #327425)</li>
</ul>
</div>
<div class="section" id="id6">
<h2>API Changes</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">selftest</span></tt> now fails if the bazaar sources contain trailing
whitespace, non-unix style line endings and files not ending in a
newline. About 372 files and 3243 lines with trailing whitespace was
updated to comply with this. The code already complied with the other
criteria, but now it is enforced. (Marius Kruger)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.branch.PushResult</span></tt> was renamed to
<tt class="docutils literal"><span class="pre">bzrlib.branch.BranchPushResult</span></tt>. (Jelmer Vernooij)</li>
<li><tt class="docutils literal"><span class="pre">Branch.fetch</span></tt> and <tt class="docutils literal"><span class="pre">Repository.fetch</span></tt> now return None rather
than a count of copied revisions and failed revisions. A while back
we stopped ever reporting failed revisions because we started
erroring instead, and the copied revisions count is not used in the
UI at all - indeed it only reflects the repository status not
changes to the branch itself. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">Inventory.apply_delta</span></tt> now raises an AssertionError if a file-id
appears multiple times within the delta. (Ian Clatworthy)</li>
<li>MutableTree.commit now favours the "authors" argument, with the old
"author" argument being deprecated.</li>
<li>Remove deprecated EmptyTree. (Martin Pool)</li>
<li><tt class="docutils literal"><span class="pre">Repository.fetch</span></tt> now accepts an optional <tt class="docutils literal"><span class="pre">fetch_spec</span></tt>
parameter. A <tt class="docutils literal"><span class="pre">SearchResult</span></tt> or <tt class="docutils literal"><span class="pre">MiniSearchResult</span></tt> may be passed
to <tt class="docutils literal"><span class="pre">fetch_spec</span></tt> instead of a <tt class="docutils literal"><span class="pre">last_revision</span></tt> to specify exactly
which revisions to fetch. (Andrew Bennetts)</li>
<li><tt class="docutils literal"><span class="pre">RepositoryAcquisitionPolicy.acquire_repository</span></tt> now returns a
tuple of <tt class="docutils literal"><span class="pre">(repository,</span> <span class="pre">is_new_flag)</span></tt>, rather than just the
repository. (Andrew Bennetts)</li>
<li>Revision.get_apparent_author() is now deprecated, replaced by
Revision.get_apparent_authors(), which returns a list. The former
now returns the first item that would be returned from the second.</li>
<li>The <tt class="docutils literal"><span class="pre">BranchBuilder</span></tt> test helper now accepts a <tt class="docutils literal"><span class="pre">timestamp</span></tt>
parameter to <tt class="docutils literal"><span class="pre">build_commit</span></tt> and <tt class="docutils literal"><span class="pre">build_snapshot</span></tt>. (Martin Pool)</li>
<li>The <tt class="docutils literal"><span class="pre">_fetch_*</span></tt> attributes on <tt class="docutils literal"><span class="pre">Repository</span></tt> are now on
<tt class="docutils literal"><span class="pre">RepositoryFormat</span></tt>, more accurately reflecting their intent (they
describe a disk format capability, not state of a particular
repository of that format). (Robert Collins)</li>
</ul>
</div>
<div class="section" id="id7">
<h2>Internals</h2>
<ul class="simple">
<li>Branching from a non-stacked branch on a smart protocol is now
free of virtual file system methods.
(Robert Collins, Andrew Bennetts)</li>
<li>Branch and Repository creation on a bzr+ssh://server are now done
via RPC calls rather than VFS calls, reducing round trips for
pushing new branches substantially. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">Branch.clone</span></tt> now takes the <tt class="docutils literal"><span class="pre">repository_policy</span></tt> formerly used
inside <tt class="docutils literal"><span class="pre">BzrDir.clone_on_transport</span></tt>, allowing stacking to be
configured before the branch tags and revision tip are set. This
fixes a race condition cloning stacked branches that would cause
plugins to have hooks called on non-stacked instances.
(Robert Collins, #334187)</li>
<li><tt class="docutils literal"><span class="pre">BzrDir.cloning_metadir</span></tt> now has a RPC call. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">BzrDirFormat.__str__</span></tt> now uses the human readable description
rather than the sometimes-absent disk label. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.fetch</span></tt> is now composed of a sender and a sink component
allowing for decoupling over a network connection. Fetching from
or into a RemoteRepository with a 1.13 server will use this to
stream the operation.
(Andrew Bennetts, Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.tests.run_suite</span></tt> accepts a runner_class parameter
supporting the use of different runners. (Robert Collins)</li>
<li>Change how file_ids and revision_ids are interned as part of
inventory deserialization. Now we use the real <tt class="docutils literal"><span class="pre">intern()</span></tt>, rather
than our own workaround that would also cache a Unicode copy of the
string, and never emptied the cache. This should slightly reduce
memory consumption. (John Arbash Meinel)</li>
<li>New branch method <tt class="docutils literal"><span class="pre">create_clone_on_transport</span></tt> that returns a
branch object. (Robert Collins)</li>
<li>New hook Commands['extend_command'] to allow plugins to access a
command object before the command is run (or help generated from
it), without overriding the command. (Robert Collins)</li>
<li>New version of the <tt class="docutils literal"><span class="pre">BzrDir.find_repository</span></tt> verb supporting
<tt class="docutils literal"><span class="pre">_network_name</span></tt> to support removing more _ensure_real calls.
(Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">RemoteBranchFormat</span></tt> no longer claims to have a disk format string.
(Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">Repository</span></tt> objects now have <tt class="docutils literal"><span class="pre">suspend_write_group</span></tt> and
<tt class="docutils literal"><span class="pre">resume_write_group</span></tt> methods. These are currently only useful
with pack repositories. (Andrew Bennetts, Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">BzrDirFormat</span></tt>, <tt class="docutils literal"><span class="pre">BranchFormat</span></tt> and <tt class="docutils literal"><span class="pre">RepositoryFormat</span></tt> objects
now have a <tt class="docutils literal"><span class="pre">network_name</span></tt> for passing the format across RPC calls.
(Robert Collins, Andrew Bennetts)</li>
<li><tt class="docutils literal"><span class="pre">RepositoryFormat</span></tt> objects now all have a new attribute
<tt class="docutils literal"><span class="pre">_serializer</span></tt> used by fetch when reserialising is required.
(Robert Collins, Andrew Bennetts)</li>
<li>Some methods have been pulled up from <tt class="docutils literal"><span class="pre">BzrBranch</span></tt> to <tt class="docutils literal"><span class="pre">Branch</span></tt>
to aid branch types that are not bzr branch objects (like
RemoteBranch). (Robert Collins, Andrew Bennetts)</li>
<li>Test adaptation has been made consistent throughout the built in
tests. <tt class="docutils literal"><span class="pre">TestScenarioApplier</span></tt>, <tt class="docutils literal"><span class="pre">multiply_tests_from_modules</span></tt>,
<tt class="docutils literal"><span class="pre">adapt_tests</span></tt>, <tt class="docutils literal"><span class="pre">adapt_modules</span></tt> have all been deleted. Please
use <tt class="docutils literal"><span class="pre">multiply_tests</span></tt>, or for lower level needs <tt class="docutils literal"><span class="pre">apply_scenarios</span></tt>
and <tt class="docutils literal"><span class="pre">apply_scenario</span></tt>. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">TestSkipped</span></tt> is now detected by TestCase and passed to the
<tt class="docutils literal"><span class="pre">TestResult</span></tt> by calling <tt class="docutils literal"><span class="pre">addSkip</span></tt>. For older TestResult objects,
where <tt class="docutils literal"><span class="pre">addSkip</span></tt> is not available, <tt class="docutils literal"><span class="pre">addError</span></tt> is still called.
This permits test filtering in subunit to strip out skipped tests
resulting in a faster fix-shrink-list-run cycle. This is compatible
with the testtools protocol for skips. (Robert Collins)</li>
<li>The <tt class="docutils literal"><span class="pre">_index</span></tt> of <tt class="docutils literal"><span class="pre">KnitVersionedFiles</span></tt> now supports the ability
to scan an underlying index that is going to be incorporated into
the <tt class="docutils literal"><span class="pre">KnitVersionedFiles</span></tt> object, to determine if it has missing
delta references. The method is <tt class="docutils literal"><span class="pre">scan_unvalidated_index</span></tt>.
(Andrew Bennetts, Robert Collins)</li>
<li>There is a RemoteSink object which handles pushing to smart servers.
(Andrew Bennetts, Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">TransportTraceDecorator</span></tt> now logs <tt class="docutils literal"><span class="pre">put_bytes_non_atomic</span></tt> and
<tt class="docutils literal"><span class="pre">rmdir</span></tt> calls. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">VersionedFiles</span></tt> record adapters have had their signature change
from <tt class="docutils literal"><span class="pre">(record,</span> <span class="pre">record.get_bytes_as(record.storage_kind))</span></tt> to
<tt class="docutils literal"><span class="pre">(record)</span></tt> reducing excess duplication and allowing adapters
to access private data in record to obtain content more
efficiently. (Robert Collins)</li>
<li>We no longer probe to see if we should create a working tree during
clone if we cannot get a local_abspath for the new bzrdir.

<p>This release of Bazaar contains many improvements to the speed,
documentation and functionality of <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span></tt> and the display of logged
revisions by <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">status</span></tt>. bzr now also gives a better indication of
progress, both in the way operations are drawn onto a text terminal, and
by showing the rate of network IO.</p>

<h2>Changes from RC1 to Final</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">init</span> <span class="pre">--development-wt5[-rich-root]</span></tt> would fail because of
circular import errors. (John Arbash Meinel, #328135)</li>

<tt class="docutils literal"><span class="pre">log-formats</span></tt>. (Ian Clatworthy)</li>
</ul>
</div>
<div class="section" id="id9">
<h2>Compatibility Breaks</h2>
<ul class="simple">
<li>By default, <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">status</span></tt> after a merge now shows just the pending
merge tip revisions. This improves the signal-to-noise ratio after
merging from trunk and completes much faster. To see all merged
revisions, use the new <tt class="docutils literal"><span class="pre">-v</span></tt> flag. (Ian Clatworthy)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">--line</span></tt> now shows any tags after the date and before
the commit message. If you have scripts which parse the output

(Ian Clatworthy)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">--short</span></tt> now shows any additional revision properties
after the date and before the commit message. Scripts that parse
output of the log command in this situation may need to adjust.
(Neil Martinsen-Burrell)</li>
<li>The experimental formats <tt class="docutils literal"><span class="pre">1.12-preview</span></tt> and <tt class="docutils literal"><span class="pre">1.12-preview-rich-root</span></tt>
have been renamed <tt class="docutils literal"><span class="pre">development-wt5</span></tt> and <tt class="docutils literal"><span class="pre">development-wt5-rich-root</span></tt>
respectively, given they are not ready for release in 1.12.

<li><tt class="docutils literal"><span class="pre">read_bundle_from_url</span></tt> has been deprecated. (Vincent Ladeuil)</li>
</ul>

<div class="section" id="id10">
<h2>New Features</h2>
<ul class="simple">
<li>Add support for filtering <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">missing</span></tt> on revisions. Remote revisions
can be filtered using <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">missing</span> <span class="pre">-r</span> <span class="pre">-20..-10</span></tt> and local revisions can
be filtered using <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">missing</span> <span class="pre">--my-revision</span> <span class="pre">-20..-10</span></tt>.
(Marius Kruger)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">-p</span></tt> displays the patch diff for each revision.

A value of 0 (zero) means "show all nested merge revisions" while

<p>This first monthly release of Bazaar for 2009 improves Bazaar's operation
in Windows, Mac OS X, and other situations where file names are matched
without regard to capitalization: Bazaar tries to match the case of an
existing file. This release of Bazaar also improves the efficiency of
Tortoise Windows Shell integration and lets it work on 64-bit platforms.</p>
<p>The UI through which Bazaar supports historic formats has been improved,
so 'bzr help formats' now gives a simpler and shorter list, with clear

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.

<li>Signatures to transfer are calculated more efficiently in

<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.

<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

These indexes are both smaller and faster for access to historical
information. (John Arbash Meinel)</li>
</ul>
</div>
<div class="section" id="id32">
<h2>Improvements</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">BTreeIndex</span></tt> code now is able to prefetch extra pages to help tune
the tradeoff between bandwidth and latency. Should be tuned
appropriately to not impact commands which need minimal information,
but provide a significant boost to ones that need more context. Only
has a direct impact on the <tt class="docutils literal"><span class="pre">--development2</span></tt> format which uses
btree's for the indexes. (John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">dump-btree</span></tt> is a hidden command introduced to allow dumping
the contents of a compressed btree file. (John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">pack</span></tt> now tells the index builders to optimize for size. For
btree index repositories, this can save 25% of the index size
(mostly in the text indexes). (John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">push</span></tt> to an existing branch or repository on a smart server
is faster, due to Bazaar making more use of the <tt class="docutils literal"><span class="pre">get_parent_map</span></tt>
RPC when querying the remote branch's revision graph.
(Andrew Bennetts)</li>
<li>default username for bzr+ssh and sftp can be configured in
authentication.conf. (Aaron Bentley)</li>
<li>launchpad-login now provides a default username for bzr+ssh and sftp
URLs, allowing username-free URLs to work for everyone. (Aaron Bentley)</li>
<li><tt class="docutils literal"><span class="pre">lp:</span></tt> lookups no longer include usernames, making them shareable and
shorter. (Aaron Bentley)</li>
<li>New <tt class="docutils literal"><span class="pre">PackRepository.autopack</span></tt> smart server RPC, which does
autopacking entirely on the server. This is much faster than
autopacking via plain file methods, which downloads a large amount
of pack data and then re-uploads the same pack data into a single
file. This fixes a major (although infrequent) cause of lengthy
delays when using a smart server. For example, pushing the 10th
revision to a repository with 9 packs now takes 44 RPCs rather than
179, and much less bandwidth too. This requires Bazaar 1.9 on both
the client and the server, otherwise the client will fallback to the
slower method. (Andrew Bennetts)</li>

<h2>Bug Fixes</h2>

(Andrew Bennetts, #270397)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">co</span></tt> uses less memory. It used to unpack the entire WT into
memory before writing it to disk. This was a little bit faster, but

<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">missing</span> <span class="pre">--quiet</span></tt> no longer prints messages about whether
there are missing revisions. The exit code indicates whether there
were or not. (Martin Pool, #284748)</li>
<li>Fixes to the <tt class="docutils literal"><span class="pre">annotate</span></tt> code. The fast-path which re-used the
stored deltas was accidentally disabled all the time, instead of
only when a branch was stacked. Second, the code would accidentally
re-use a delta even if it wasn't against the left-parent, this
could only happen if <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">reconcile</span></tt> decided that the parent
ordering was incorrect in the file graph. (John Arbash Meinel)</li>

<li>Some compatibility fixes for building the extensions with MSVC and

<li>The index logic is now able to reload the list of pack files if and
index ends up disappearing. We still don't reload if the pack data
itself goes missing after checking the index. This bug appears as a
transient failure (file not found) when another process is writing
to the repository. (John Arbash Meinel, #153786)</li>

restore the branch to that tip using <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">pull</span></tt>. 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 <tt class="docutils literal"><span class="pre">bzr://</span></tt>.
(Martin Pool, #261315)</li>
<li><tt class="docutils literal"><span class="pre">SFTPTransport.readv()</span></tt> was accidentally using <tt class="docutils literal"><span class="pre">list</span> <span class="pre">+=</span> <span class="pre">string</span></tt>,
which 'works', but adds each character separately to the list,
rather than using <tt class="docutils literal"><span class="pre">list.append(string)</span></tt>. 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 <tt class="docutils literal"><span class="pre">_buffer_all</span></tt> 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 <tt class="docutils literal"><span class="pre">_buffer_all</span></tt> 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>

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 <tt class="docutils literal"><span class="pre">show_tree_status</span></tt> function should be aware that
the show_pending flag is now authoritative for showing pending
merges, as it was originally. (Robert Collins, #225204)</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 <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">cat-revision</span></tt>. (Jelmer Vernooij, #175569)</li>

<li><tt class="docutils literal"><span class="pre">bzrlib.btree_index</span></tt> is now available, providing a b-tree index

<p>This release fixes a few regressions found in the 1.6 client. Fetching
changes was using an O(N^2) buffering algorithm, so for large projects it
would cause memory thrashing. There is also a specific problem with the
<tt class="docutils literal"><span class="pre">--1.6-rich-root</span></tt> format, which prevented stacking on top of
<tt class="docutils literal"><span class="pre">--rich-root-pack</span></tt> repositories, and could allow users to accidentally
fetch experimental data (<tt class="docutils literal"><span class="pre">-subtree</span></tt>) without representing it properly.
The <tt class="docutils literal"><span class="pre">--1.6-rich-root</span></tt> format has been deprecated and users are
recommended to upgrade to <tt class="docutils literal"><span class="pre">--1.6.1-rich-root</span></tt> immediately. Also we
re-introduced a workaround for users who have repositories with incorrect
nodes (not possible if you only used official releases).
I should also clarify that none of this is data loss level issues, but
still sufficient enough to warrant an updated release.</p>
<div class="section" id="id57">
<h2>Bug Fixes</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">RemoteTransport.readv()</span></tt> was being inefficient about how it
buffered the readv data and processed it. It would keep appending to
the same string (causing many copies) and then pop bytes out of the
start of the string (causing more copies).
With this patch "bzr+ssh://local" can improve dramatically,
especially for projects with large files.
(John Arbash Meinel)</li>
<li>Revision texts were always meant to be stored as fulltexts. There
was a bug in a bzr.dev version that would accidentally create deltas
when copying from a Pack repo to a Knit repo. This has been fixed,
but to support those repositories, we know always request full texts
for Revision texts. (John Arbash Meinel, #261339)</li>
<li>The previous <tt class="docutils literal"><span class="pre">--1.6-rich-root</span></tt> format used an incorrect xml
serializer, which would accidentally support fetching from a

not. We deprecated that format, and introduced a new one that uses

<h2>API Changes</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">MutableTree.commit</span></tt> has an extra optional keywork parameter
<tt class="docutils literal"><span class="pre">exclude</span></tt> that will be unconditionally supplied by the command
line UI - plugins that add tree formats may need an update.
(Robert Collins)</li>
<li>The API minimum version for plugin compatibility has been raised to
1.6 - there are significant changes throughout the code base.
(Robert Collins)</li>
<li>The generic fetch code now uses three attributes on Repository objects
to control fetch. The streams requested are controlled via :
<tt class="docutils literal"><span class="pre">_fetch_order</span></tt> and <tt class="docutils literal"><span class="pre">_fetch_uses_deltas</span></tt>. Setting these
appropriately allows different repository implementations to recieve
data in their optimial form. If the <tt class="docutils literal"><span class="pre">_fetch_reconcile</span></tt> is set then
a reconcile operation is triggered at the end of the fetch.
(Robert Collins)</li>
<li>The <tt class="docutils literal"><span class="pre">put_on_disk</span></tt> and <tt class="docutils literal"><span class="pre">get_tar_item</span></tt> methods in

need one in the first place (nobody cached the value, and
<tt class="docutils literal"><span class="pre">RemoteRepository</span></tt> wasn't taking one either). This saves a round
trip when probing Pack repositories, as they read the <tt class="docutils literal"><span class="pre">pack-names</span></tt>

(See the user guide for more details.) It also adds a new hook, improved
weaves, aliases for related locations, faster bzr+ssh push, and several
bug fixes.</p>

<ul class="simple">
<li>Bazaar is now able to be a client to the web server of IIS 6 and 7.

<h2>Internals</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">Branch.missing_revisions</span></tt> has been deprecated. Similar functionality
can be obtained using <tt class="docutils literal"><span class="pre">bzrlib.missing.find_unmerged</span></tt>. The api was
fairly broken, and the function was unused, so we are getting rid of it.
(John Arbash Meinel)</li>
</ul>

<div class="section" id="id88">
<h2>API Changes</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">Branch.abspath</span></tt> is deprecated; use the Tree or Transport
instead. (Martin Pool)</li>
<li><tt class="docutils literal"><span class="pre">Branch.update_revisions</span></tt> now takes an optional <tt class="docutils literal"><span class="pre">Graph</span></tt>
object. This can be used by <tt class="docutils literal"><span class="pre">update_revisions</span></tt> when it is
checking ancestry, and allows callers to prefer request to go to a
local branch. (John Arbash Meinel)</li>
<li>Branch, Repository, Tree and BzrDir should expose a Transport as an
attribute if they have one, rather than having it indirectly accessible
as <tt class="docutils literal"><span class="pre">.control_files._transport</span></tt>. This doesn't add a requirement
to support a Transport in cases where it was not needed before;
it just simplifies the way it is reached. (Martin Pool)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">missing</span> <span class="pre">--mine-only</span></tt> will return status code 0 if you have no
new revisions, but the remote does. Similarly for <tt class="docutils literal"><span class="pre">--theirs-only</span></tt>.
The new code only checks one side, so it doesn't know if the other
side has changes. This seems more accurate with the request anyway.
It also changes the output to print '[This|Other] branch is up to
date.' rather than displaying nothing. (John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">LockableFiles.put_utf8</span></tt>, <tt class="docutils literal"><span class="pre">put_bytes</span></tt> and <tt class="docutils literal"><span class="pre">controlfilename</span></tt>
are now deprecated in favor of using Transport operations.
(Martin Pool)</li>
<li>Many methods on <tt class="docutils literal"><span class="pre">VersionedFile</span></tt>, <tt class="docutils literal"><span class="pre">Repository</span></tt> and in
<tt class="docutils literal"><span class="pre">bzrlib.revision</span></tt> deprecated before bzrlib 1.5 have been removed.
(Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">RevisionSpec.wants_revision_history</span></tt> can be set to False for a given
<tt class="docutils literal"><span class="pre">RevisionSpec</span></tt>. This will disable the existing behavior of passing in
the full revision history to <tt class="docutils literal"><span class="pre">self._match_on</span></tt>. Useful for specs that
don't actually need access to the full history. (John Arbash Meinel)</li>
<li>The constructors of <tt class="docutils literal"><span class="pre">SmartClientMedium</span></tt> and its subclasses now require a
<tt class="docutils literal"><span class="pre">base</span></tt> parameter. <tt class="docutils literal"><span class="pre">SmartClientMedium</span></tt> implementations now also need
to provide a <tt class="docutils literal"><span class="pre">remote_path_from_transport</span></tt> method. (Andrew Bennetts)</li>
<li>The default permissions for creating new files and directories
should now be obtained from <tt class="docutils literal"><span class="pre">BzrDir._get_file_mode()</span></tt> and
<tt class="docutils literal"><span class="pre">_get_dir_mode()</span></tt>, rather than from LockableFiles. The <tt class="docutils literal"><span class="pre">_set_file_mode</span></tt>
and <tt class="docutils literal"><span class="pre">_set_dir_mode</span></tt> variables on LockableFiles which were advertised
as a way for plugins to control this are no longer consulted.
(Martin Pool)</li>
<li><tt class="docutils literal"><span class="pre">VersionedFile.join</span></tt> is deprecated. This method required local
instances of both versioned file objects and was thus hostile to being
used for streaming from a smart server. The new get_record_stream and
insert_record_stream are meant to efficiently replace this method.
(Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">WorkingTree.set_parent_(ids/trees)</span></tt> will now filter out revisions
which are in the ancestry of other revisions. So if you merge the same
tree twice, or merge an ancestor of an existing merge, it will only
record the newest. (If you merge a descendent, it will replace its
ancestor). (John Arbash Meinel, #235407)</li>
<li><tt class="docutils literal"><span class="pre">WorkingTreeFormat2.stub_initialize_remote</span></tt> is now private.

warning when selftest ends to remind us of leaking tests.
(Vincent Ladeuil, #226769)</li>
<li>Fetching all revisions from a repository does not cause pack collisions.
(Robert Collins, Aaron Bentley, #212908)</li>
<li>Fix error about "attempt to add line-delta in non-delta knit".
(Andrew Bennetts, #217701)</li>
<li>Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would break
if the remote server was < version 1.2. This was due to a bug in the
RemoteRepository.get_parent_map() fallback code.
(John Arbash Meinel, #214894)</li>
<li>Remove leftover code in <tt class="docutils literal"><span class="pre">bzr_branch</span></tt> that inappropriately creates
a <tt class="docutils literal"><span class="pre">branch-name</span></tt> file in the branch control directory.
(Martin Pool)</li>

<li>Parameterised test ids are preserved correctly to aid diagnosis of test
failures. (Robert Collins, Andrew Bennetts)</li>
<li>selftest now accepts --starting-with <id> to load only the tests whose id
starts with the one specified. This greatly speeds up running the test
suite on a limited set of tests and can be used to run the tests for a
single module, a single class or even a single test. (Vincent Ladeuil)</li>
<li>The test suite modules have been modified to define load_tests() instead
of test_suite(). That speeds up selective loading (via --load-list)
significantly and provides many examples on how to migrate (grep for
load_tests). (Vincent Ladeuil)</li>

<li>bzr main script cannot be imported (Benjamin Peterson)</li>
<li>On Linux bzr additionally looks for plugins in arch-independent site

<li>The <tt class="docutils literal"><span class="pre">set_rh</span></tt> branch hook is now deprecated. Please migrate
any plugins using this hook to use an alternative, e.g.
<tt class="docutils literal"><span class="pre">post_change_branch_tip</span></tt>. (Ian Clatworthy)</li>
<li>When a plugin cannot be loaded as the file path is not a valid
python module name bzr will now strip a <tt class="docutils literal"><span class="pre">bzr_</span></tt> prefix from the
front of the suggested name, as many plugins (e.g. bzr-svn)
want to be installed without this prefix. It is a common mistake
to have a folder named "bzr-svn" for that plugin, especially
as this is what bzr branch lp:bzr-svn will give you. (James Westby,

Wouter van Heyst)</li>
<li>Diff is now more specific about execute-bit changes it describes
(Chad Miller)</li>
<li>Fetching data over HTTP is a bit faster when urllib is used. This is done
by forcing it to recv 64k at a time when reading lines in HTTP headers,
rather than just 1 byte at a time. (Andrew Bennetts)</li>
<li>Log --short and --line are much faster when -r is not specified.
(Aaron Bentley)</li>

when merging the execute bit. (Aaron Bentley)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">status</span></tt> on an explicit list of files no longer shows pending
merges, making it much faster on large trees. (John Arbash Meinel)</li>
<li>The launchpad directory service now warns the user if they have not set
their launchpad login and are trying to resolve a URL using it, just
in case they want to do a write operation with it. (James Westby)</li>
<li>The smart protocol client is slightly faster, because it now only queries
the server for the protocol version once per connection. Also, the HTTP
transport will now automatically probe for and use a smart server if
one is present. You can use the new <tt class="docutils literal"><span class="pre">nosmart+</span></tt> transport decorator
to get the old behaviour. (Andrew Bennetts)</li>

version number, for easier use in scripts. (Martin Pool)</li>

<li>Fixed <tt class="docutils literal"><span class="pre">_get_line</span></tt> in <tt class="docutils literal"><span class="pre">bzrlib.smart.medium</span></tt>, which was buggy. Also
fixed <tt class="docutils literal"><span class="pre">_get_bytes</span></tt> in the same module to use the push back buffer.
These bugs had no known impact in normal use, but were problematic for

<li>Implement handling of basename parameter for DefaultMail. (James Westby)</li>
<li>Incompatibility with Paramiko versions newer than 1.7.2 was fixed.

(Robert Collins)</li>
<li>New smart method, <tt class="docutils literal"><span class="pre">Repository.stream_revisions_chunked</span></tt>, for fetching
revision data that streams revision data via a chunked encoding. This

<h2>Notes When Upgrading</h2>
<ul>
<li><p class="first">The default repository format is now <tt class="docutils literal"><span class="pre">pack-0.92</span></tt>. This
default is used when creating new repositories with <tt class="docutils literal"><span class="pre">init</span></tt> and
<tt class="docutils literal"><span class="pre">init-repo</span></tt>, and when branching over bzr+ssh or bzr+hpss.
(See <a class="reference external" href="https://bugs.launchpad.net/bugs/164626">https://bugs.launchpad.net/bugs/164626</a>)</p>
<p>This format can be read and written by Bazaar 0.92 and later, and
data can be transferred to and from older formats.</p>
<p>To upgrade, please reconcile your repository (<tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">reconcile</span></tt>), and then
upgrade (<tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">upgrade</span></tt>).</p>
<p><tt class="docutils literal"><span class="pre">pack-0.92</span></tt> offers substantially better scaling and performance than the
previous knits format. Some operations are slower where the code already
had bad scaling characteristics under knits, the pack format makes such
operations more visible as part of being more scalable overall. We will
correct such operations over the coming releases and encourage the filing
of bugs on any operation which you observe to be slower in a packs
repository. One particular case that we do not intend to fix is pulling
data from a pack repository into a knit repository over a high latency
link; downgrading such data requires reinsertion of the file texts, and
this is a classic space/time tradeoff. The current implementation is
conservative on memory usage because we need to support converting data
from any tree without problems.

<h2>Performance</h2>

<li>Commit no longer checks for new text keys during insertion when the
revision id was deterministically unique. (Robert Collins)</li>
<li>Committing a change which is not a merge and does not change the number of
files in the tree is faster by utilising the data about whether files are
changed to determine if the tree is unchanged rather than recalculating
it at the end of the commit process. (Robert Collins)</li>
<li>Inventory serialisation no longer double-sha's the content.
(Robert Collins)</li>
<li>Knit text reconstruction now avoids making copies of the lines list for
interim texts when building a single text. The new <tt class="docutils literal"><span class="pre">apply_delta</span></tt> method
on <tt class="docutils literal"><span class="pre">KnitContent</span></tt> aids this by allowing modification of the revision id
such objects represent. (Robert Collins)</li>
<li>Pack indices are now partially parsed for specific key lookup using a
bisection approach. (Robert Collins)</li>
<li>Partial commits are now approximately 40% faster by walking over the
unselected current tree more efficiently. (Robert Collins)</li>
<li>XML inventory serialisation takes 20% less time while being stricter about
the contents. (Robert Collins)</li>

fixes a bug introduced in bzr 0.91. (Andrew Bennetts, #146715)</li>
<li>Commands reporting exceptions can now be profiled and still have their
data correctly dumped to a file. For example, a <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">commit</span></tt> with
no changes still reports the operation as pointless but doing so no

<li>The CommitBuilder method <tt class="docutils literal"><span class="pre">record_entry_contents</span></tt> now returns summary

<h2>Changes</h2>
<ul class="simple">
<li>The default branch and repository format has changed to
<tt class="docutils literal"><span class="pre">dirstate-tags</span></tt>, so tag commands are active by default.
This format is compatible with Bazaar 0.15 and later.
This incidentally fixes bug #126141.

<li><tt class="docutils literal"><span class="pre">--quiet</span></tt> or <tt class="docutils literal"><span class="pre">-q</span></tt> is no longer a global option. If present, it
must now appear after the command name. Scripts doing things like

(Ian Clatworthy)</li>
</ul>

<div class="section" id="id164">
<h2>Features</h2>
<ul>
<li><p class="first">New option <tt class="docutils literal"><span class="pre">--author</span></tt> in <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">commit</span></tt> to specify the author of the
change, if it's different from the committer. <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span></tt> and
<tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">annotate</span></tt> display the author instead of the committer.
(Lukáš Lalinský)</p>
</li>
<li><p class="first">In addition to global options and command specific options, a set of
standard options are now supported. Standard options are legal for
all commands. The initial set of standard options are:</p>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">--help</span></tt> or <tt class="docutils literal"><span class="pre">-h</span></tt> - display help message</li>
<li><tt class="docutils literal"><span class="pre">--verbose</span></tt> or <tt class="docutils literal"><span class="pre">-v</span></tt> - display additional information</li>
<li><tt class="docutils literal"><span class="pre">--quiet</span></tt> or <tt class="docutils literal"><span class="pre">-q</span></tt> - only output warnings and errors.</li>
</ul>
<p>Unlike global options, standard options can be used in aliases and
may have command-specific help. (Ian Clatworthy)</p>
</li>
<li><p class="first">Verbosity level processing has now been unified. If <tt class="docutils literal"><span class="pre">--verbose</span></tt>
or <tt class="docutils literal"><span class="pre">-v</span></tt> is specified on the command line multiple times, the
verbosity level is made positive the first time then increased.
If <tt class="docutils literal"><span class="pre">--quiet</span></tt> or <tt class="docutils literal"><span class="pre">-q</span></tt> is specified on the command line
multiple times, the verbosity level is made negative the first
time then decreased. To get the default verbosity level of zero,
either specify none of the above , <tt class="docutils literal"><span class="pre">--no-verbose</span></tt> or <tt class="docutils literal"><span class="pre">--no-quiet</span></tt>.
Note that most commands currently ignore the magnitude of the
verbosity level but do respect <em>quiet vs normal vs verbose</em> when
generating output. (Ian Clatworthy)</p>
</li>
<li><p class="first"><tt class="docutils literal"><span class="pre">Branch.hooks</span></tt> now supports <tt class="docutils literal"><span class="pre">pre_commit</span></tt> hook. The hook's signature
is documented in BranchHooks constructor. (Nam T. Nguyen, #102747)</p>
</li>
<li><p class="first">New <tt class="docutils literal"><span class="pre">Repository.stream_knit_data_for_revisions</span></tt> request added to the
network protocol for greatly reduced roundtrips when retrieving a set of
revisions. (Andrew Bennetts)</p>

<h2>Bug Fixes</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">plugins</span></tt> now lists the version number for each plugin in square
brackets after the path. (Robert Collins, #125421)</li>
<li>Pushing, pulling and branching branches with subtree references was not
copying the subtree weave, preventing the file graph from being accessed
and causing errors in commits in clones. (Robert Collins)</li>
<li>Suppress warning "integer argument expected, got float" from Paramiko,
which sometimes caused false test failures. (Martin Pool)</li>
<li>Fix bug in bundle 4 that could cause attempts to write data to wrong
versionedfile. (Aaron Bentley)</li>
<li>Diffs generated using "diff -p" no longer break the patch parser.
(Aaron Bentley)</li>
<li>get_transport treats an empty possible_transports list the same as a non-
empty one. (Aaron Bentley)</li>
<li>patch verification for merge directives is reactivated, and works with
CRLF and CR files. (Aaron Bentley)</li>
<li>Accept ..as a path in revision specifiers. This fixes for example
"-r branch:..other-branch" on Windows. (Lukáš Lalinský)</li>
<li><tt class="docutils literal"><span class="pre">BZR_PLUGIN_PATH</span></tt> may now contain trailing slashes.
(Blake Winton, #129299)</li>
<li>man page no longer lists hidden options (#131667, Aaron Bentley)</li>
<li><tt class="docutils literal"><span class="pre">uncommit</span> <span class="pre">--help</span></tt> now explains the -r option adequately. (Daniel
Watkins, #106726)</li>
<li>Error messages are now better formatted with parameters (such as
filenames) quoted when necessary. This avoids confusion when directory
names ending in a '.' at the end of messages were confused with a
full stop that may or not have been there. (Daniel Watkins, #129791)</li>
<li>Fix <tt class="docutils literal"><span class="pre">status</span> <span class="pre">FILE</span> <span class="pre">-r</span> <span class="pre">X..Y</span></tt>. (Lukáš Lalinský)</li>
<li>If a particular command is an alias, <tt class="docutils literal"><span class="pre">help</span></tt> will show the alias
instead of claiming there is no help for said alias. (Daniel Watkins,
#133548)</li>
<li>TreeTransform-based operations, like pull, merge, revert, and branch,
now roll back if they encounter an error. (Aaron Bentley, #67699)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">commit</span></tt> now exits cleanly if a character unsupported by the
current encoding is used in the commit message. (Daniel Watkins,
#116143)</li>
<li>bzr send uses default values for ranges when only half of an elipsis
is specified ("-r..5" or "-r5.."). (#61685, Aaron Bentley)</li>
<li>Avoid trouble when Windows ssh calls itself 'plink' but no plink
binary is present. (Martin Albisetti, #107155)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">remove</span></tt> should remove clean subtrees. Now it will remove (without
needing <tt class="docutils literal"><span class="pre">--force</span></tt>) subtrees that contain no files with text changes or
modified files. With <tt class="docutils literal"><span class="pre">--force</span></tt> it removes the subtree regardless of
text changes or unknown files. Directories with renames in or out (but
not changed otherwise) will now be removed without needing <tt class="docutils literal"><span class="pre">--force</span></tt>.
Unknown ignored files will be deleted without needing <tt class="docutils literal"><span class="pre">--force</span></tt>.
(Marius Kruger, #111665)</li>
<li>When two plugins conflict, the source of both the losing and now the
winning definition is shown. (Konstantin Mikhaylov, #5454)</li>
<li>When committing to a branch, the location being committed to is
displayed. (Daniel Watkins, #52479)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">--version</span></tt> takes care about encoding of stdout, especially
when output is redirected. (Alexander Belchenko, #131100)</li>
<li>Prompt for an ftp password if none is provided.
(Vincent Ladeuil, #137044)</li>
<li>Reuse bound branch associated transport to avoid multiple
connections.
(Vincent Ladeuil, #128076, #131396)</li>
<li>Overwrite conflicting tags by <tt class="docutils literal"><span class="pre">push</span></tt> and <tt class="docutils literal"><span class="pre">pull</span></tt> if the
<tt class="docutils literal"><span class="pre">--overwrite</span></tt> option is specified. (Lukáš Lalinský, #93947)</li>
<li>In checkouts, tags are copied into the master branch when created,
changed or deleted, and are copied into the checkout when it is
updated. (Martin Pool, #93856, #93860)</li>
<li>Print a warning instead of aborting the <tt class="docutils literal"><span class="pre">python</span> <span class="pre">setup.py</span> <span class="pre">install</span></tt>
process if building of a C extension is not possible.

<h2>Improvements</h2>
<ul class="simple">
<li>Add the option "--show-diff" to the commit command in order to display

<li>Help on debug flags is now included in <tt class="docutils literal"><span class="pre">help</span> <span class="pre">global-options</span></tt>.
(Daniel Watkins, #124853)</li>
<li>Parameters passed on the command line are checked to ensure they are
supported by the encoding in use. (Daniel Watkins)</li>
<li>The compression used within the bzr repository has changed from zlib
level 9 to the zlib default level. This improves commit performance with
only a small increase in space used (and in some cases a reduction in
space). (Robert Collins)</li>
<li>Initial commit no longer SHAs files twice and now reuses the path
rather than looking it up again, making it faster.
(Ian Clatworthy)</li>
<li>New option <tt class="docutils literal"><span class="pre">-c</span></tt>/<tt class="docutils literal"><span class="pre">--change</span></tt> for <tt class="docutils literal"><span class="pre">diff</span></tt> and <tt class="docutils literal"><span class="pre">status</span></tt> to show
changes in one revision. (Lukáš Lalinský)</li>
<li>If versioned files match a given ignore pattern, a warning is now
given. (Daniel Watkins, #48623)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">status</span></tt> now has -S as a short name for --short and -V as a
short name for --versioned. These have been added to assist users
migrating from Subversion: <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">status</span> <span class="pre">-SV</span></tt> is now like
<tt class="docutils literal"><span class="pre">svn</span> <span class="pre">status</span> <span class="pre">-q</span></tt>. (Daniel Watkins, #115990)</li>
<li>Added C implementation of <tt class="docutils literal"><span class="pre">PatienceSequenceMatcher</span></tt>, which is about
10x faster than the Python version. This speeds up commands that

inconsistent with revision and inventory info, and <tt class="docutils literal"><span class="pre">reconcile</span></tt> can fix
them. These faulty references were generated by 0.8-era releases,

<li>CommitBuilder now advertises itself as requiring the root entry to be
supplied. This only affects foreign repository implementations which reuse
CommitBuilder directly and have changed record_entry_contents to require
that the root not be supplied. This should be precisely zero plugins
affected. (Robert Collins)</li>
<li>The <tt class="docutils literal"><span class="pre">add_lines</span></tt> methods on <tt class="docutils literal"><span class="pre">VersionedFile</span></tt> implementations has changed

<div class="section" id="id169">
<h2>Internals</h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzrlib.plugin.all_plugins</span></tt> has been deprecated in favour of
<tt class="docutils literal"><span class="pre">bzrlib.plugin.plugins()</span></tt> which returns PlugIn objects that provide
useful functionality for determining the path of a plugin, its tests, and
its version information. (Robert Collins)</li>
<li>Add the option user_encoding to the function 'show_diff_trees()'
in order to move the user encoding at the UI level. (Goffredo Baroncelli)</li>
<li>Add the function make_commit_message_template_encoded() and the function
edit_commit_message_encoded() which handle encoded strings.
This is done in order to mix the commit messages (which is a unicode
string), and the diff which is a raw string. (Goffredo Baroncelli)</li>
<li>CommitBuilder now defaults to using add_lines_with_ghosts, reducing
overhead on non-weave repositories which don't require all parents to be
present. (Robert Collins)</li>
<li>Deprecated method <tt class="docutils literal"><span class="pre">find_previous_heads</span></tt> on
<tt class="docutils literal"><span class="pre">bzrlib.inventory.InventoryEntry</span></tt>. This has been superseded by the use
of <tt class="docutils literal"><span class="pre">parent_candidates</span></tt> and a separate heads check via the repository
API. (Robert Collins)</li>
<li>New trace function <tt class="docutils literal"><span class="pre">mutter_callsite</span></tt> will print out a subset of the
stack to the log, which can be useful for gathering debug details.
(Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.pack.ContainerWriter</span></tt> now tracks how many records have been
added via a public attribute records_written. (Robert Collins)</li>
<li>New method <tt class="docutils literal"><span class="pre">bzrlib.transport.Transport.get_recommended_page_size</span></tt>.
This provides a hint to users of transports as to the reasonable
minimum data to read. In principle this can take latency and
bandwidth into account on a per-connection basis, but for now it
just has hard coded values based on the url. (e.g. <a class="reference external" href="http://">http://</a> has a large
page size, <a class="reference external" href="file://">file://</a> has a small one.) (Robert Collins)</li>
<li>New method on <tt class="docutils literal"><span class="pre">bzrlib.transport.Transport</span></tt> <tt class="docutils literal"><span class="pre">open_write_stream</span></tt> allows
incremental addition of data to a file without requiring that all the
data be buffered in memory. (Robert Collins)</li>
<li>New methods on <tt class="docutils literal"><span class="pre">bzrlib.knit.KnitVersionedFile</span></tt>:
<tt class="docutils literal"><span class="pre">get_data_stream(versions)</span></tt>, <tt class="docutils literal"><span class="pre">insert_data_stream(stream)</span></tt> and
<tt class="docutils literal"><span class="pre">get_format_signature()</span></tt>. These provide some infrastructure for
efficiently streaming the knit data for a set of versions over the smart
protocol.</li>
<li>Knits with no annotation cache still produce correct annotations.
(Aaron Bentley)</li>
<li>Three new methods have been added to <tt class="docutils literal"><span class="pre">bzrlib.trace</span></tt>:
<tt class="docutils literal"><span class="pre">set_verbosity_level</span></tt>, <tt class="docutils literal"><span class="pre">get_verbosity_level</span></tt> and <tt class="docutils literal"><span class="pre">is_verbose</span></tt>.
<tt class="docutils literal"><span class="pre">set_verbosity_level</span></tt> expects a numeric value: negative for quiet,
zero for normal, positive for verbose. The size of the number can be
used to determine just how quiet or verbose the application should be.
The existing <tt class="docutils literal"><span class="pre">be_quiet</span></tt> and <tt class="docutils literal"><span class="pre">is_quiet</span></tt> routines have been
integrated into this new scheme. (Ian Clatworthy)</li>
<li>Options can now be delcared with a <tt class="docutils literal"><span class="pre">custom_callback</span></tt> parameter. If
set, this routine is called after the option is processed. This feature
is now used by the standard options <tt class="docutils literal"><span class="pre">verbose</span></tt> and <tt class="docutils literal"><span class="pre">quiet</span></tt> so that
setting one implicitly resets the other. (Ian Clatworthy)</li>
<li>Rather than declaring a new option from scratch in order to provide
custom help, a centrally registered option can be decorated using the
new <tt class="docutils literal"><span class="pre">bzrlib.Option.custom_help</span></tt> routine. In particular, this routine
is useful when declaring better help for the <tt class="docutils literal"><span class="pre">verbose</span></tt> and <tt class="docutils literal"><span class="pre">quiet</span></tt>
standard options as the base definition of these is now more complex
than before thanks to their use of a custom callback. (Ian Clatworthy)</li>
<li>Tree._iter_changes(specific_file=[]) now iterates through no files,
instead of iterating through all files. None is used to iterate through
all files. (Aaron Bentley)</li>
<li>WorkingTree.revert() now accepts None to revert all files. The use of
[] to revert all files is deprecated. (Aaron Bentley)</li>

<li>New <tt class="docutils literal"><span class="pre">pack</span></tt> command that will trigger database compression within
the repository (Robert Collins)</li>
<li>Implement <tt class="docutils literal"><span class="pre">_KnitIndex._load_data</span></tt> in a pyrex extension. The pyrex
version is approximately 2-3x faster at parsing a <tt class="docutils literal"><span class="pre">.kndx</span></tt> file.
Which yields a measurable improvement for commands which have to
read from the repository, such as a 1s => 0.75s improvement in
<tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">diff</span></tt> when there are changes to be shown. (John Arbash Meinel)</li>
<li>Merge is now faster. Depending on the scenario, it can be more than 2x
faster. (Aaron Bentley)</li>
<li>Give a clearer warning, and allow <tt class="docutils literal"><span class="pre">python</span> <span class="pre">setup.py</span> <span class="pre">install</span></tt> to
succeed even if pyrex is not available.
(John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">DirState._read_dirblocks</span></tt> now has an optional Pyrex
implementation. This improves the speed of any command that has to
read the entire DirState. (<tt class="docutils literal"><span class="pre">diff</span></tt>, <tt class="docutils literal"><span class="pre">status</span></tt>, etc, improve by
about 10%).
<tt class="docutils literal"><span class="pre">bisect_dirblocks</span></tt> has also been improved, which helps all
<tt class="docutils literal"><span class="pre">_get_entry</span></tt> type calls (whenever we are searching for a

(John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">pull</span></tt> and <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">push</span></tt> no longer do a complete walk of the

<li>The <tt class="docutils literal"><span class="pre">plugins</span></tt> command is now public with improved help.
(Ian Clatworthy)</li>
<li>New bundle and merge directive formats are faster to generate, and</li>
<li>Annotate merge now works when there are local changes. (Aaron Bentley)</li>
<li>Commit now only shows the progress in terms of directories instead of
entries. (Ian Clatworthy)</li>
<li>Fix <tt class="docutils literal"><span class="pre">KnitRepository.get_revision_graph</span></tt> to not request the graph 2
times. This makes <tt class="docutils literal"><span class="pre">get_revision_graph</span></tt> 2x faster. (John Arbash
Meinel)</li>
<li>Fix <tt class="docutils literal"><span class="pre">VersionedFile.get_graph()</span></tt> to avoid using
<tt class="docutils literal"><span class="pre">set.difference_update(other)</span></tt>, which has bad scaling when
<tt class="docutils literal"><span class="pre">other</span></tt> is large. This improves <tt class="docutils literal"><span class="pre">VF.get_graph([version_id])</span></tt> for
a 12.5k graph from 2.9s down to 200ms. (John Arbash Meinel)</li>
<li>The <tt class="docutils literal"><span class="pre">--lsprof-file</span></tt> option now generates output for KCacheGrind if
the file starts with <tt class="docutils literal"><span class="pre">callgrind.out</span></tt>. This matches the default file
filtering done by KCacheGrind's Open Dialog. (Ian Clatworthy)</li>
<li>Fix <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">update</span></tt> to avoid an unnecessary
<tt class="docutils literal"><span class="pre">branch.get_master_branch</span></tt> call, which avoids 1 extra connection
to the remote server. (Partial fix for #128076, John Arbash Meinel)</li>
<li>Log errors from the smart server in the trace file, to make debugging
test failures (and live failures!) easier. (Andrew Bennetts)</li>
<li>The HTML version of the man page has been superceded by a more
comprehensive manual called the Bazaar User Reference. This manual
is completed generated from the online help topics. As part of this
change, limited reStructuredText is now explicitly supported in help
topics and command help with 'unnatural' markup being removed prior
to display by the online help or inclusion in the man page.

<li>HTML documentation now use files extension <tt class="docutils literal"><span class="pre">*.html</span></tt>

<h2>Library API Breaks</h2>
<ul class="simple">
<li>Deprecated dictionary <tt class="docutils literal"><span class="pre">bzrlib.option.SHORT_OPTIONS</span></tt> removed.
Options are now required to provide a help string and it must
comply with the style guide by being one or more sentences with an
initial capital and final period. (Martin Pool)</li>
<li>KnitIndex.get_parents now returns tuples. (Robert Collins)</li>
<li>Ancient unused <tt class="docutils literal"><span class="pre">Repository.text_store</span></tt> attribute has been removed.
(Robert Collins)</li>
<li>The <tt class="docutils literal"><span class="pre">bzrlib.pack</span></tt> interface has changed to use tuples of bytestrings
rather than just bytestrings, making it easier to represent multiple
element names. As this interface was not used by any internal facilities
since it was introduced in 0.18 no API compatibility is being preserved.
The serialised form of these packs is identical with 0.18 when a single
element tuple is in use. (Robert Collins)</li>
</ul>
</div>
<div class="section" id="id174">
<h2>Internals</h2>
<ul class="simple">
<li>merge now uses <tt class="docutils literal"><span class="pre">iter_changes</span></tt> to calculate changes, which makes room for
future performance increases. It is also more consistent with other
operations that perform comparisons, and reduces reliance on
Tree.inventory. (Aaron Bentley)</li>
<li>Refactoring of transport classes connected to a remote server.
ConnectedTransport is a new class that serves as a basis for all
transports needing to connect to a remote server. transport.split_url
have been deprecated, use the static method on the object instead. URL
tests have been refactored too.
(Vincent Ladeuil)</li>
<li>Better connection sharing for ConnectedTransport objects.
transport.get_transport() now accepts a 'possible_transports' parameter.
If a newly requested transport can share a connection with one of the
list, it will.
(Vincent Ladeuil)</li>
<li>Most functions now accept <tt class="docutils literal"><span class="pre">bzrlib.revision.NULL_REVISION</span></tt> to indicate
the null revision, and consider using <tt class="docutils literal"><span class="pre">None</span></tt> for this purpose
deprecated. (Aaron Bentley)</li>
<li>New <tt class="docutils literal"><span class="pre">index</span></tt> module with abstract index functionality. This will be
used during the planned changes in the repository layer. Currently the
index layer provides a graph aware immutable index, a builder for the
same index type to allow creating them, and finally a composer for
such indices to allow the use of many indices in a single query. The
index performance is not optimised, however the API is stable to allow
development on top of the index. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.dirstate.cmp_by_dirs</span></tt> can be used to compare two paths by
their directory sections. This is equivalent to comparing
<tt class="docutils literal"><span class="pre">path.split('/')</span></tt>, only without having to split the paths.
This has a Pyrex implementation available.
(John Arbash Meinel)</li>
<li>New transport decorator 'unlistable+' which disables the list_dir
functionality for testing.</li>
<li>Deprecated <tt class="docutils literal"><span class="pre">change_entry</span></tt> in transform.py. (Ian Clatworthy)</li>
<li>RevisionTree.get_weave is now deprecated. Tree.plan_merge is now used
for performing annotate-merge. (Aaron Bentley)</li>
<li>New EmailMessage class to create email messages. (Adeodato Simó)</li>
<li>Unused functions on the private interface KnitIndex have been removed.
(Robert Collins)</li>
<li>New <tt class="docutils literal"><span class="pre">knit.KnitGraphIndex</span></tt> which provides a <tt class="docutils literal"><span class="pre">KnitIndex</span></tt> layered on top
of a <tt class="docutils literal"><span class="pre">index.GraphIndex</span></tt>. (Robert Collins)</li>
<li>New <tt class="docutils literal"><span class="pre">knit.KnitVersionedFile.iter_parents</span></tt> method that allows querying
the parents of many knit nodes at once, reducing round trips to the
underlying index. (Robert Collins)</li>
<li>Graph now has an is_ancestor method, various bits use it.
(Aaron Bentley)</li>
<li>The <tt class="docutils literal"><span class="pre">-Dhpss</span></tt> flag now includes timing information. As well as
logging when a new connection is opened. (John Arbash Meinel)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.pack.ContainerWriter</span></tt> now returns an offset, length tuple to
callers when inserting data, allowing generation of readv style access
during pack creation, without needing a separate pass across the output
pack to gather such details. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.pack.make_readv_reader</span></tt> allows readv based access to pack
files that are stored on a transport. (Robert Collins)</li>
<li>New <tt class="docutils literal"><span class="pre">Repository.has_same_location</span></tt> method that reports if two
repository objects refer to the same repository (although with some risk
of false negatives). (Andrew Bennetts)</li>
<li>InterTree.compare now passes require_versioned on correctly.
(Marius Kruger)</li>
<li>New methods on Repository - <tt class="docutils literal"><span class="pre">start_write_group</span></tt>,
<tt class="docutils literal"><span class="pre">commit_write_group</span></tt>, <tt class="docutils literal"><span class="pre">abort_write_group</span></tt> and <tt class="docutils literal"><span class="pre">is_in_write_group</span></tt> -
which provide a clean hook point for transactional Repositories - ones
where all the data for a fetch or commit needs to be made atomically
available in one step. This allows the write lock to remain while making
a series of data insertions. (e.g. data conversion). (Robert Collins)</li>
<li>In <tt class="docutils literal"><span class="pre">bzrlib.knit</span></tt> the internal interface has been altered to use
3-tuples (index, pos, length) rather than two-tuples (pos, length) to
describe where data in a knit is, allowing knits to be split into
many files. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">bzrlib.knit._KnitData</span></tt> split into cache management and physical access
with two access classes - <tt class="docutils literal"><span class="pre">_PackAccess</span></tt> and <tt class="docutils literal"><span class="pre">_KnitAccess</span></tt> defined.
The former provides access into a .pack file, and the latter provides the
current production repository form of .knit files. (Robert Collins)</li>

<h2>Notes When Upgrading</h2>
<ul>
<li><p class="first">The kind() and is_executable() APIs on the WorkingTree interface no
longer implicitly (read) locks and unlocks the tree. This <em>might</em>
impact some plug-ins and tools using this part of the API. If you find
an issue that may be caused by this change, please let us know,
particularly the plug-in/tool maintainer. If encountered, the API
fix is to surround kind() and is_executable() calls with lock_read()
and unlock() like so:</p>
<pre class="literal-block">
work_tree.lock_read()
try:
kind = work_tree.kind(...)
finally:
work_tree.unlock()

<h2>Internals</h2>
<ul class="simple">
<li>Rework of LogFormatter API to provide beginning/end of log hooks and to
encapsulate the details of the revision to be logged in a LogRevision
object.
In long log formats, merge revision ids are only shown when --show-ids
is specified, and are labelled "revision-id:", as per mainline
revisions, instead of "merged:". (Kent Gibson)</li>
<li>New <tt class="docutils literal"><span class="pre">BranchBuilder</span></tt> API which allows the construction of particular

improving speed. 3.25x speedups have been observed for construction of
kernel-sized-trees, and checkouts are 1.28x faster. (Aaron Bentley)</li>
<li>Commit on large trees is now faster. In my environment, a commit of
a small change to the Mozilla tree (55k files) has dropped from
66 seconds to 32 seconds. For a small tree of 600 files, commit of a
small change is 33% faster. (Ian Clatworthy)</li>

<li>The bzr protocol version 2 indicates success or failure in every response
without depending on particular commands encoding that consistently,
allowing future client refactorings to be much more robust about error

<li>The smart protocol over HTTP client has been changed to always post to the
same <tt class="docutils literal"><span class="pre">.bzr/smart</span></tt> URL under the original location when it can. This allows

<li>digest authentication is now supported for proxies and HTTP by the urllib

2.6.5. Basic and digest authentication are handled coherently for HTTP
and proxy: if the user is provided in the url (bzr command line for HTTP,
proxy environment variables for proxies), the password is prompted for
(only once). If the password is provided, it is taken into account. Once
the first authentication is successful, all further authentication
roundtrips are avoided by preventively setting the right authentication
header(s).

<h2>Internals</h2>

<li>bzrlib API compatability with 0.8 has been dropped, cleaning up some

<li>Change the format of chroot urls so that they can be safely manipulated
by generic url utilities without causing the resulting urls to have
escaped the chroot. A side effect of this is that creating a chroot
requires an explicit action using a ChrootServer.
(Robert Collins, Andrew Bennetts)</li>
<li>Deprecate <tt class="docutils literal"><span class="pre">Branch.get_root_id()</span></tt> because branches don't have root ids,

<li>New SmartServer hooks facility. There are two initial hooks documented
in <tt class="docutils literal"><span class="pre">bzrlib.transport.smart.SmartServerHooks</span></tt>. The two initial hooks allow
plugins to execute code upon server startup and shutdown.
(Robert Collins).</li>
<li>SmartServer in standalone mode will now close its listening socket
when it stops, rather than waiting for garbage collection. This primarily
fixes test suite hangs when a test tries to connect to a shutdown server.
It may also help improve behaviour when dealing with a server running
on a specific port (rather than dynamically assigned ports).
(Robert Collins)</li>
<li>Move most SmartServer code into a new package, bzrlib/smart.

<li>urllib http implementation avoid roundtrips associated with

authentication when the user is required to type a password.

<li>Renamed SmartTransport (and subclasses like SmartTCPTransport) to
RemoteTransport (and subclasses to RemoteTCPTransport, etc). This is more
consistent with its new home in <tt class="docutils literal"><span class="pre">bzrlib/transport/remote.py</span></tt>, and because
it's not really a "smart" transport, just one that does file operations

<li>New function <tt class="docutils literal"><span class="pre">Branch.get_revision_id_to_revno_map</span></tt> which will

<li>Add new <tt class="docutils literal"><span class="pre">vfs_transport_factory</span></tt> attribute on tests which provides the

This allows the RemoteObject tests to back onto local disk or memory,
and use the existing <tt class="docutils literal"><span class="pre">transport_server</span></tt> attribute all tests know about
to be the smart server transport. This in turn allows tests to
differentiate between 'transport to access the branch', and
'transport which is a VFS' - which matters in Remote* tests.

<li>The <tt class="docutils literal"><span class="pre">make_branch_and_tree</span></tt> method for tests will now create a
lightweight checkout for the tree if the <tt class="docutils literal"><span class="pre">vfs_transport_factory</span></tt> is not

<div class="section" id="surprises">
<h2>Surprises</h2>
<ul class="simple">
<li>The default disk format has changed. Please run 'bzr upgrade' in your
working trees to upgrade. This new default is compatible for network
operations, but not for local operations. That is, if you have two
versions of bzr installed locally, after upgrading you can only use the
bzr 0.15 version. This new default does not enable tags or nested-trees
as they are incompatible with bzr versions before 0.15 over the network.</li>
<li>For users of bzrlib: Two major changes have been made to the working tree
api in bzrlib. The first is that many methods and attributes, including
the inventory attribute, are no longer valid for use until one of
<tt class="docutils literal"><span class="pre">lock_read</span></tt>/<tt class="docutils literal"><span class="pre">lock_write</span></tt>/<tt class="docutils literal"><span class="pre">lock_tree_write</span></tt> has been called,
and become invalid again after unlock is called. This has been done
to improve performance and correctness as part of the dirstate
development.
(Robert Collins, John A Meinel, Martin Pool, and others).</li>
<li>For users of bzrlib: The attribute 'tree.inventory' should be considered
readonly. Previously it was possible to directly alter this attribute, or
its contents, and have the tree notice this. This has been made
unsupported - it may work in some tree formats, but in the newer dirstate
format such actions will have no effect and will be ignored, or even
cause assertions. All operations possible can still be carried out by a
combination of the tree API, and the bzrlib.transform API. (Robert
Collins, John A Meinel, Martin Pool, and others).</li>
</ul>
</div>
<div class="section" id="id204">
<h2>Improvements</h2>
<ul class="simple">
<li>Support for OS Windows 98. Also .bzr.log on any windows system
saved in My Documents folder. (Alexander Belchenko)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">mv</span></tt> enhanced to support already moved files.
In the past the mv command would have failed if the source file doesn't
exist. In this situation <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">mv</span></tt> would now detect that the file has
already moved and update the repository accordingly, if the target file
does exist.
A new option <tt class="docutils literal"><span class="pre">--after</span></tt> has been added so that if two files already
exist, you could notify Bazaar that you have moved a (versioned) file
and replaced it with another. Thus in this case <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">move</span> <span class="pre">--after</span></tt>

<li>Branch format 6: smaller, and potentially faster than format 5. Supports
<tt class="docutils literal"><span class="pre">append_history_only</span></tt> mode, where the log view and revnos do not change,
except by being added to. Stores policy settings in
".bzr/branch/branch.conf".</li>
<li><tt class="docutils literal"><span class="pre">append_only</span></tt> branches: Format 6 branches may be configured so that log
view and revnos are always consistent. Either create the branch using
"bzr init --append-revisions-only" or edit the config file as descriped
in docs/configuration.txt.</li>
<li>rebind: Format 6 branches retain the last-used bind location, so if you
"bzr unbind", you can "bzr bind" to bind to the previously-selected
bind location.</li>
<li>Builtin tags support, created and deleted by the <tt class="docutils literal"><span class="pre">tag</span></tt> command and
stored in the branch. Tags can be accessed with the revisionspec
<tt class="docutils literal"><span class="pre">-rtag:</span></tt>, and listed with <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">tags</span></tt>. Tags are not versioned

upgrade, run <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">upgrade</span> <span class="pre">--dirstate-tags</span></tt> in your branch and
repositories. (Martin Pool)</li>
<li>The <tt class="docutils literal"><span class="pre">bzr://</span></tt> transport now has a well-known port number, 4155,

<h2>Internals</h2>
<ul class="simple">
<li>Internally revision ids and file ids are now passed around as utf-8
bytestrings, rather than treating them as Unicode strings. This has
performance benefits for Knits, since we no longer need to decode the
revision id for each line of content, nor for each entry in the index.
This will also help with the future dirstate format.
(John Arbash Meinel)</li>
<li>Reserved ids (any revision-id ending in a colon) are rejected by
versionedfiles, repositories, branches, and working trees
(Aaron Bentley)</li>
<li>Minor performance improvement by not creating a ProgressBar for
every KnitIndex we create. (about 90ms for a bzr.dev tree)
(John Arbash Meinel)</li>
<li>New easier to use Branch hooks facility. There are five initial hooks,
all documented in bzrlib.branch.BranchHooks.__init__ - <tt class="docutils literal"><span class="pre">'set_rh'</span></tt>,
<tt class="docutils literal"><span class="pre">'post_push'</span></tt>, <tt class="docutils literal"><span class="pre">'post_pull'</span></tt>, <tt class="docutils literal"><span class="pre">'post_commit'</span></tt>,
<tt class="docutils literal"><span class="pre">'post_uncommit'</span></tt>. These hooks fire after the matching operation
on a branch has taken place, and were originally added for the
branchrss plugin. (Robert Collins)</li>
<li>New method <tt class="docutils literal"><span class="pre">Branch.push()</span></tt> which should be used when pushing from a
branch as it makes performance and policy decisions to match the UI
level command <tt class="docutils literal"><span class="pre">push</span></tt>. (Robert Collins).</li>
<li>Add a new method <tt class="docutils literal"><span class="pre">Tree.revision_tree</span></tt> which allows access to cached
trees for arbitrary revisions. This allows the in development dirstate
tree format to provide access to the callers to cached copies of
inventory data which are cheaper to access than inventories from the
repository.
(Robert Collins, Martin Pool)</li>
<li>New <tt class="docutils literal"><span class="pre">Branch.last_revision_info</span></tt> method, this is being done to allow
optimization of requests for both the number of revisions and the last
revision of a branch with smartservers and potentially future branch
formats. (Wouter van Heyst, Robert Collins)</li>
<li>Allow <tt class="docutils literal"><span class="pre">'import</span> <span class="pre">bzrlib.plugins.NAME'</span></tt> to work when the plugin NAME has not
yet been loaded by <tt class="docutils literal"><span class="pre">load_plugins()</span></tt>. This allows plugins to depend on each
other for code reuse without requiring users to perform file-renaming
gymnastics. (Robert Collins)</li>
<li>New Repository method <tt class="docutils literal"><span class="pre">'gather_stats'</span></tt> for statistic data collection.
This is expected to grow to cover a number of related uses mainly
related to bzr info. (Robert Collins)</li>
<li>Log formatters are now managed with a registry.
<tt class="docutils literal"><span class="pre">log.register_formatter</span></tt> continues to work, but callers accessing
the FORMATTERS dictionary directly will not.</li>
<li>Allow a start message to be passed to the <tt class="docutils literal"><span class="pre">edit_commit_message</span></tt>
function. This will be placed in the message offered to the user
for editing above the separator. It allows a template commit message
to be used more easily. (James Westby)</li>
<li><tt class="docutils literal"><span class="pre">GPGStrategy.sign()</span></tt> will now raise <tt class="docutils literal"><span class="pre">BzrBadParameterUnicode</span></tt> if
you pass a Unicode string rather than an 8-bit string. Callers need
to be updated to encode first. (John Arbash Meinel)</li>
<li>Branch.push, pull, merge now return Result objects with information
about what happened, rather than a scattering of various methods. These
are also passed to the post hooks. (Martin Pool)</li>
<li>File formats and architecture is in place for managing a forest of trees
in bzr, and splitting up existing trees into smaller subtrees, and
finally joining trees to make a larger tree. This is the first iteration
of this support, and the user-facing aspects still require substantial
work. If you wish to experiment with it, use <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">upgrade</span>
<span class="pre">--dirstate-with-subtree</span></tt> in your working trees and repositories.
You can use the hidden commands <tt class="docutils literal"><span class="pre">split</span></tt> and <tt class="docutils literal"><span class="pre">join</span></tt> and to create
and manipulate nested trees, but please consider using the nested-trees
branch, which contains substantial UI improvements, instead.

<li>Replace broken fnmatch based ignore pattern matching with custom pattern

(Kent Gibson, Jan Hudec #57637)</li>
<li>pycurl and urllib can detect short reads at different places. Update
the test suite to test more cases. Also detect http error code 416
which was raised for that specific bug. Also enhance the urllib
robustness by detecting invalid ranges (and pycurl's one by detecting
short reads during the initial GET). (Vincent Ladeuil, #73948)</li>

<h2>Internals</h2>
<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.

<li>New test helper classs MemoryTree. This is typically accessed via

the 'action' passed to <tt class="docutils literal"><span class="pre">smart_add_tree()</span></tt> can return <tt class="docutils literal"><span class="pre">file_ids</span></tt> that

(John Arbash Meinel, #55781)</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">selftest</span> <span class="pre">--benchmark</span></tt> now allows a <tt class="docutils literal"><span class="pre">--cache-dir</span></tt> parameter.

<li>Inverse forms are provided for all boolean options. For example,

<li>Really fix mutter() so that it won't ever raise a UnicodeError.
It means it is possible for ~/.bzr.log to contain non UTF-8 characters.
But it is a debugging log, not a real user file.
(John Arbash Meinel, #56947, #53880)</li>
<li>Change Command handle to allow Unicode command and options.
At present we cannot register Unicode command names, so we will get
BzrCommandError('unknown command'), or BzrCommandError('unknown option')
But that is better than a UnicodeError + a traceback.
(John Arbash Meinel, #57123)</li>

<li>The hard-coded built-in ignore rules have been removed. There are
now two rulesets which are enforced. A user global one in

specific one '.bzrignore'.
<tt class="docutils literal"><span class="pre">~/.bazaar/ignore</span></tt> will be created if it does not exist, but with
a more conservative list than the old default.
This fixes bugs with default rules being enforced no matter what.
The old list of ignore rules from bzr is available by
running 'bzr ignore --old-default-rules'.
(Robert Collins, Martin Pool, John Arbash Meinel)</li>
<li>'branches.conf' has been changed to 'locations.conf', since it can apply

<h2>Improvements</h2>
<ul class="simple">
<li>The revision specifier "revno:" is extended to accept the syntax
revno:N:branch. For example,
revno:42:http://bazaar-vcs.org/bzr/bzr.dev/ means revision 42 in
bzr.dev. (Matthieu Moy)</li>
<li>Tests updates to ensure proper URL handling, UNICODE support, and
proper printing when the user's terminal encoding cannot display
the path of a file that has been versioned.
<tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">branch</span></tt> can take a target URL rather than only a local directory.
<tt class="docutils literal"><span class="pre">Branch.get_parent()/set_parent()</span></tt> now save a relative path if possible,
and normalize the parent based on root, allowing access across
different transports. (John Arbash Meinel, Wouter van Heyst, Martin Pool)
(Malone #48906, #42699, #40675, #5281, #3980, #36363, #43689,
#42517, #42514)</li>
<li>On Unix, detect terminal width using an ioctl not just $COLUMNS.
Use terminal width for single-line logs from <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">--line</span></tt> and
pending-merge display. (Robert Widhopf-Fenk, Gustavo Niemeyer)
(Malone #3507)</li>
<li>On Windows, detect terminal width using GetConsoleScreenBufferInfo.
(Alexander Belchenko)</li>
<li>Speedup improvement for 'date:'-revision search. (Guillaume Pinot).</li>
<li>Show the correct number of revisions pushed when pushing a new branch.
(Robert Collins).</li>
<li>'bzr selftest' now shows a progress bar with the number of tests, and
progress made. 'make check' shows tests in -v mode, to be more useful
for the PQM status window. (Robert Collins).
When using a progress bar, failed tests are printed out, rather than
being overwritten by the progress bar until the suite finishes.
(John Arbash Meinel)</li>
<li>'bzr selftest --benchmark' will run a new benchmarking selftest.
'bzr selftest --benchmark --lsprof-timed' will use lsprofile to generate
profile data for the individual profiled calls, allowing for fine
grained analysis of performance.
(Robert Collins, Martin Pool).</li>
<li>'bzr commit' shows a progress bar. This is useful for commits over sftp
where commit can take an appreciable time. (Robert Collins)</li>
<li>'bzr add' is now less verbose in telling you what ignore globs were
matched by files being ignored. Instead it just tells you how many
were ignored (because you might reasonably be expecting none to be
ignored). 'bzr add -v' is unchanged and will report every ignored
file. (Robert Collins).</li>
<li>ftp now has a test server if medusa is installed. As part of testing,
ftp support has been improved, including support for supplying a
non-standard port. (John Arbash Meinel).</li>
<li>'bzr log --line' shows the revision number, and uses only the
first line of the log message (#5162, Alexander Belchenko;
Matthieu Moy)</li>
<li>'bzr status' has had the --all option removed. The 'bzr ls' command
should be used to retrieve all versioned files. (Robert Collins)</li>
<li>'bzr bundle OTHER/BRANCH' will create a bundle which can be sent
over email, and applied on the other end, while maintaining ancestry.
This bundle can be applied with either 'bzr merge' or 'bzr pull',
the same way you would apply another branch.
(John Arbash Meinel, Aaron Bentley)</li>
<li>'bzr whoami' can now be used to set your identity from the command line,
for a branch or globally. (Robey Pointer)</li>
<li>'bzr checkout' now aliased to 'bzr co', and 'bzr annotate' to 'bzr ann'.
(Michael Ellerman)</li>
<li>'bzr revert DIRECTORY' now reverts the contents of the directory as well.

<li>'bzr get sftp://foo' gives a better error when paramiko is not present.
Also updates things like 'http+pycurl://' if pycurl is not present.
(John Arbash Meinel) (Malone #47821, #52204)</li>
<li>New env variable <tt class="docutils literal"><span class="pre">BZR_PROGRESS_BAR</span></tt>, sets the default progress bar type.
Can be set to 'none' or 'dummy' to disable the progress bar, 'dots' or
'tty' to create the respective type. (John Arbash Meinel, #42197, #51107)</li>
<li>Improve the help text for 'bzr diff' to explain what various options do.
(John Arbash Meinel, #6391)</li>
<li>'bzr uncommit -r 10' now uncommits revisions 11.. rather than uncommitting
revision 10. This makes -r10 more in line with what other commands do.
'bzr uncommit' also now saves the pending merges of the revisions that
were removed. So it is safe to uncommit after a merge, fix something,
and commit again. (John Arbash Meinel, #32526, #31426)</li>
<li>'bzr init' now also works on remote locations.
(Wouter van Heyst, #48904)</li>
<li>HTTP support has been updated. When using pycurl we now support
connection keep-alive, which reduces dns requests and round trips.
And for both urllib and pycurl we support multi-range requests,
which decreases the number of round-trips. Performance results for
<tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">branch</span> <span class="pre">http://bazaar-vcs.org/bzr/bzr.dev/</span></tt> indicate
http branching is now 2-3x faster, and <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">pull</span></tt> in an existing
branch is as much as 4x faster.
(Michael Ellerman, Johan Rydberg, John Arbash Meinel, #46768)</li>
<li>Performance improvements for sftp. Branching and pulling are now up to
2x faster. Utilize paramiko.readv() support for async requests if it

<h2>Notes When Upgrading</h2>
<p>Release 0.8 of bzr introduces a new format for history storage, called
'knit', as an evolution of to the 'weave' format used in 0.7. Local
and remote operations are faster using knits than weaves. Several
operations including 'init', 'init-repo', and 'upgrade' take a
--format option that controls this. Branching from an existing branch
will keep the same format.</p>
<p>It is possible to merge, pull and push between branches of different
formats but this is slower than moving data between homogenous
branches. It is therefore recommended (but not required) that you
upgrade all branches for a project at the same time. Information on
formats is shown by 'bzr info'.</p>
<p>bzr 0.8 now allows creation of 'repositories', which hold the history
of files and revisions for several branches. Previously bzr kept all
the history for a branch within the .bzr directory at the root of the
branch, and this is still the default. To create a repository, use
the new 'bzr init-repo' command. Branches exist as directories under
the repository and contain just a small amount of information
indicating the current revision of the branch.</p>
<p>bzr 0.8 also supports 'checkouts', which are similar to in cvs and
subversion. Checkouts are associated with a branch (optionally in a
repository), which contains all the historical information. The
result is that a checkout can be deleted without losing any
already-committed revisions. A new 'update' command is also available.</p>
<p>Repositories and checkouts are not supported with the 0.7 storage
format. To use them you must upgrad to either knits, or to the
'metaweave' format, which uses weaves but changes the .bzr directory
arrangement.</p>

<h2>Testing</h2>
<ul class="simple">
<li>SFTP tests now shortcut the SSH negotiation, reducing test overhead

<li>Branch formats are now tested once per implementation (see <tt class="docutils literal"><span class="pre">bzrlib.</span>
<span class="pre">tests.branch_implementations</span></tt>. This is analagous to the transport
interface tests, and has been followed up with working tree,

<li>New test base class TestCaseWithTransport provides a transport aware
test environment, useful for testing any transport-interface using
code. The test suite option --transport controls the transport used
by this class (when its not being used as part of implementation
contract testing). (Robert Collins)</li>
<li>Close logging handler on disabling the test log. This will remove the
handler from the internal list inside python's logging module,
preventing shutdown from closing it twice. (Olaf Conradi)</li>

<li>.bzrignore is excluded from exports, on the grounds that it's a bzr
internal-use file and may not be wanted. (Jamie Wilkinson)</li>
<li>The "bzr directories" command were removed in favor of the new
--kind option to the "bzr inventory" command. To list all
versioned directories, now use "bzr inventory --kind directory".
(Johan Rydberg)</li>
<li>Under Windows configuration directory is now <tt class="docutils literal"><span class="pre">%APPDATA%\bazaar\2.0</span></tt>
by default. (John Arbash Meinel)</li>
<li>The parent of Bzr configuration directory can be set by <tt class="docutils literal"><span class="pre">BZR_HOME</span></tt>

<li>Plugins with the same name in different directories in the bzr plugin
path are no longer loaded: only the first successfully loaded one is
used. (Robert Collins)</li>
<li>Use systems' external ssh command to open connections if possible.
This gives better integration with user settings such as ProxyCommand.
(James Henstridge)</li>
<li>Permissions on files underneath .bzr/ are inherited from the .bzr
directory. So for a shared repository, simply doing 'chmod -R g+w .bzr/'
will mean that future file will be created with group write permissions.</li>
<li>configure.in and config.guess are no longer in the builtin default
ignore list.</li>

<li>Improved performance when integrating changes from a remote weave.
(Goffredo Baroncelli)</li>
<li>Sftp will attempt to cache the connection, so it is more likely that
a connection will be reused, rather than requiring multiple password
requests.</li>
<li>bzr revno now takes an optional argument indicating the branch whose
revno should be printed. (Michael Ellerman)</li>
<li>bzr cat defaults to printing the last version of the file.

added, but doesn't actually add anything. (Michael Ellerman)</li>
<li>'bzr add' now lists how many files were ignored per glob. add --verbose
lists the specific files. (Aaron Bentley)</li>

trivially done within python, so for now its only triggered by running
Make check. Integrators and packagers who wish to check for full
platform support should run 'make check' to test the source.

reasons - see the wiki spec ImprovingBzrTestSuite).</li>
<li>Test sftp with relative, absolute-in-homedir and absolute-not-in-homedir
paths for the transport tests. Introduce blackbox remote sftp tests that
test the same permutations. (Robert Collins, Robey Pointer)</li>
<li>Transport implementation tests are now independent of the local file
system, which allows tests for esoteric transports, and for features
not available in the local file system. They also repeat for variations

<li>pull now takes --verbose to show you what revisions are added or removed
(John A Meinel)</li>
<li>merge now takes a --show-base option to include the base text in
conflicts.
(Aaron Bentley)</li>
<li>The config files are now read using ConfigObj, so '=' should be used as
a separator, not ':'.
(Aaron Bentley)</li>
<li>New 'bzr commit --strict' option refuses to commit if there are
any unknown files in the tree. To commit, make sure all files are
either ignored, added, or deleted. (Michael Ellerman)</li>
<li>The config directory is now ~/.bazaar, and there is a single file
~/.bazaar/bazaar.conf storing email, editor and other preferences.
(Robert Collins)</li>
<li>'bzr add' no longer takes a --verbose option, and a --quiet option
has been added that suppresses all output.</li>
<li>Improved zsh completion support in contrib/zsh, from Clint
Adams.</li>
<li>Builtin 'bzr annotate' command, by Martin Pool with improvements from
Goffredo Baroncelli.</li>
<li>'bzr check' now accepts -v for verbose reporting, and checks for
ghosts in the branch. (Robert Collins)</li>
<li>New command 're-sign' which will regenerate the gpg signature for
a revision. (Robert Collins)</li>
<li>If you set <tt class="docutils literal"><span class="pre">check_signatures=require</span></tt> for a path in
<tt class="docutils literal"><span class="pre">~/.bazaar/branches.conf</span></tt> then bzr will invoke your
<tt class="docutils literal"><span class="pre">gpg_signing_command</span></tt> (defaults to gpg) and record a digital signature
of your commit. (Robert Collins)</li>
<li>New sftp transport, based on Paramiko. (Robey Pointer)</li>
<li>'bzr pull' now accepts '--clobber' which will discard local changes
and make this branch identical to the source branch. (Robert Collins)</li>
<li>Just give a quieter warning if a plugin can't be loaded, and
put the details in .bzr.log. (Martin Pool)</li>
<li>'bzr branch' will now set the branch-name to the last component of the
output directory, if one was supplied.</li>
<li>If the option <tt class="docutils literal"><span class="pre">post_commit</span></tt> is set to one (or more) python function
names (must be in the bzrlib namespace), then they will be invoked
after the commit has completed, with the branch and <tt class="docutils literal"><span class="pre">revision_id</span></tt> as
parameters. (Robert Collins)</li>
<li>Merge now has a retcode of 1 when conflicts occur. (Robert Collins)</li>
<li>--merge-type weave is now supported for file contents. Tree-shape
changes are still three-way based. (Martin Pool, Aaron Bentley)</li>
<li>'bzr check' allows the first revision on revision-history to have
parents - something that is expected for cheap checkouts, and occurs
when conversions from baz do not have all history. (Robert Collins).</li>
<li>'bzr merge' can now graft unrelated trees together, if your specify
0 as a base. (Aaron Bentley)</li>
<li>'bzr commit branch' and 'bzr commit branch/file1 branch/file2' now work
(Aaron Bentley)</li>
<li>Add '.sconsign*' to default ignore list. (Alexander Belchenko)</li>
<li>'bzr merge --reprocess' minimizes conflicts</li>

<h2>Testing</h2>
<ul class="simple">
<li>The 'bzr selftest --pattern' option for has been removed, now
test specifiers on the command line can be simple strings, or
regexps, or both. (Robert Collins)</li>
<li>Passing -v to selftest will now show the time each test took to
complete, which will aid in analysing performance regressions and
related questions. (Robert Collins)</li>
<li>'bzr selftest' runs all tests, even if one fails, unless '--one'
is given. (Martin Pool)</li>
<li>There is a new method for TestCaseInTempDir, assertFileEqual, which
will check that a given content is equal to the content of the named
file. (Robert Collins)</li>
<li>Fix test suite's habit of leaving many temporary log files in $TMPDIR.
(Martin Pool)</li>
</ul>
</div>
<div class="section" id="id254">
<h2>Internals</h2>
<ul class="simple">
<li>New 'testament' command and concept for making gpg-signatures
of revisions that are not tied to a particular internal
representation. (Martin Pool).</li>
<li>Per-revision properties ('revprops') as key-value associated
strings on each revision created when the revision is committed.
Intended mainly for the use of external tools. (Martin Pool).</li>
<li>Config options have moved from bzrlib.osutils to bzrlib.config.
(Robert Collins)</li>
<li>Improved command line option definitions allowing explanations
for individual options, among other things. Contributed by
Magnus Therning.</li>
<li>Config options have moved from bzrlib.osutils to bzrlib.config.
Configuration is now done via the config.Config interface:
Depending on whether you have a Branch, a Location or no information
available, construct a <tt class="docutils literal"><span class="pre">*Config</span></tt>, and use its <tt class="docutils literal"><span class="pre">signature_checking</span></tt>,
<tt class="docutils literal"><span class="pre">username</span></tt> and <tt class="docutils literal"><span class="pre">user_email</span></tt> methods. (Robert Collins)</li>
<li>Plugins are now loaded under bzrlib.plugins, not bzrlib.plugin, and
they are made available for other plugins to use. You should not
import other plugins during the <tt class="docutils literal"><span class="pre">__init__</span></tt> of your plugin though, as
no ordering is guaranteed, and the plugins directory is not on the
python path. (Robert Collins)</li>
<li>Branch.relpath has been moved to WorkingTree.relpath. WorkingTree no
no longer takes an inventory, rather it takes an option branch
parameter, and if None is given will open the branch at basedir
implicitly. (Robert Collins)</li>
<li>Cleaner exception structure and error reporting. Suggested by
Scott James Remnant. (Martin Pool)</li>
<li>Branch.remove has been moved to WorkingTree, which has also gained
<tt class="docutils literal"><span class="pre">lock_read</span></tt>, <tt class="docutils literal"><span class="pre">lock_write</span></tt> and <tt class="docutils literal"><span class="pre">unlock</span></tt> methods for convenience.
(Robert Collins)</li>
<li>Two decorators, <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> have been
added to the branch module. Use these to cause a function to run in a
read or write lock respectively. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">Branch.open_containing</span></tt> now returns a tuple (Branch, relative-path),
which allows direct access to the common case of 'get me this file
from its branch'. (Robert Collins)</li>
<li>Transports can register using <tt class="docutils literal"><span class="pre">register_lazy_transport</span></tt>, and they
will be loaded when first used. (Martin Pool)</li>
<li>'pull' has been factored out of the command as <tt class="docutils literal"><span class="pre">WorkingTree.pull()</span></tt>.
A new option to WorkingTree.pull has been added, clobber, which will
ignore diverged history and pull anyway.
(Robert Collins)</li>
<li>config.Config has a <tt class="docutils literal"><span class="pre">get_user_option</span></tt> call that accepts an option name.
This will be looked up in branches.conf and bazaar.conf as normal.
It is intended that this be used by plugins to support options -
options of built in programs should have specific methods on the config.
(Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">merge.merge_inner</span></tt> now has tempdir as an optional parameter.
(Robert Collins)</li>
<li>Tree.kind is not recorded at the top level of the hierarchy, as it was
missing on EmptyTree, leading to a bug with merge on EmptyTrees.
(Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">WorkingTree.__del__</span></tt> has been removed, it was non deterministic and not
doing what it was intended to. See <tt class="docutils literal"><span class="pre">WorkingTree.__init__</span></tt> for a comment
about future directions. (Robert Collins/Martin Pool)</li>
<li>bzrlib.transport.http has been modified so that only 404 urllib errors
are returned as NoSuchFile. Other exceptions will propogate as normal.
This allows debuging of actual errors. (Robert Collins)</li>
<li>bzrlib.transport.Transport now accepts <em>ONLY</em> url escaped relative paths
to apis like 'put', 'get' and 'has'. This is to provide consistent
behaviour - it operates on url's only. (Robert Collins)</li>
<li>Transports can register using <tt class="docutils literal"><span class="pre">register_lazy_transport</span></tt>, and they
will be loaded when first used. (Martin Pool)</li>
<li><tt class="docutils literal"><span class="pre">merge_flex</span></tt> no longer calls <tt class="docutils literal"><span class="pre">conflict_handler.finalize()</span></tt>, instead that
is called by <tt class="docutils literal"><span class="pre">merge_inner</span></tt>. This is so that the conflict count can be
retrieved (and potentially manipulated) before returning to the caller
of <tt class="docutils literal"><span class="pre">merge_inner</span></tt>. Likewise 'merge' now returns the conflict count to the
caller. (Robert Collins)</li>
<li><tt class="docutils literal"><span class="pre">revision.revision_graph</span></tt> can handle having only partial history for
a revision - that is no revisions in the graph with no parents.
(Robert Collins).</li>
<li>New <tt class="docutils literal"><span class="pre">builtins.branch_files</span></tt> uses the standard <tt class="docutils literal"><span class="pre">file_list</span></tt> rules to
produce a branch and a list of paths, relative to that branch
(Aaron Bentley)</li>
<li>New TestCase.addCleanup facility.</li>
<li>New <tt class="docutils literal"><span class="pre">bzrlib.version_info</span></tt> tuple (similar to <tt class="docutils literal"><span class="pre">sys.version_info</span></tt>),
which can be used by programs importing bzrlib.</li>

<li><tt class="docutils literal"><span class="pre">bzr</span></tt> with no command now shows help rather than giving an
error. Suggested by Michael Ellerman.</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">status</span></tt> output format changed, because svn-style output
doesn't really match the model of bzr. Now files are grouped by
status and can be shown with their IDs. <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">status</span> <span class="pre">--all</span></tt>
shows all versioned files and unknown files but not ignored files.</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">log</span></tt> runs from most-recent to least-recent, the reverse
of the previous order. The previous behaviour can be obtained
with the <tt class="docutils literal"><span class="pre">--forward</span></tt> option.</li>
<li><tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">inventory</span></tt> by default shows only filenames, and also ids
if <tt class="docutils literal"><span class="pre">--show-ids</span></tt> is given, in which case the id is the second
field.</li>

a filename.</li>
<li>Commands can now be defined by external programs or scripts
in a directory on $BZRPATH.</li>
<li>New "stat cache" avoids reading the contents of files if they
haven't changed since the previous time.</li>
<li>If the Python interpreter is too old, try to find a better one

<li>New optional parameter <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">info</span> <span class="pre">[BRANCH]</span></tt>.</li>

<h2>Testing</h2>
<ul class="simple">
<li>Converted black-box test suites from Bourne shell into Python;
now run using <tt class="docutils literal"><span class="pre">./testbzr</span></tt>. Various structural improvements to
the tests.</li>
<li>testbzr by default runs the version of bzr found in the same
directory as the tests, or the one given as the first parameter.</li>
<li>testbzr also runs the internal tests, so the only command
required to check is just <tt class="docutils literal"><span class="pre">./testbzr</span></tt>.</li>
<li>testbzr requires python2.4, but can be used to test bzr running
under a different version.</li>
