<h3>Changes From 1.13.1 to 1.13.2<a class="headerlink" href="#changes-from-1-13-1-to-1-13-2" title="Permalink to this headline">¶</a></h3>
<p>A regression was found in the 1.13.1 release. When bzr 1.13.1 and earlier push
a stacked branch they do not take care to push all the parent inventories for
the transferred revisions. This means that a smart server serving that branch
often cannot calculate inventory deltas for the branch (because smart server
does not/cannot open fallback repositories). Prior to 1.13 the server did not
have a verb to stream revisions out of a repository, so that’s why this bug has
appeared now.</p>

<h3>Improvements<a class="headerlink" href="#improvements" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>All bzr <code class="docutils literal notranslate"><span class="pre">Hooks</span></code> classes are now registered in
<code class="docutils literal notranslate"><span class="pre">bzrlib.hooks.known_hooks</span></code>. This removes the separate list from
<code class="docutils literal notranslate"><span class="pre">bzrlib.tests</span></code> and ensures that all hooks registered there are
correctly isolated by the test suite (previously
<code class="docutils literal notranslate"><span class="pre">MutableTreeHooks</span></code> were not being isolated correctly). Further,
documentation for hooks is now dynamically generated from the
present HookPoints. <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">hooks</span></code> will now also report on all the
hooks present in the <code class="docutils literal notranslate"><span class="pre">bzrlib.hooks.known_hooks</span></code> registry.
(Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">add</span></code> no longer prints <code class="docutils literal notranslate"><span class="pre">add</span> <span class="pre">completed</span></code> on success. Failure
still prints an error message. (Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">branch</span></code> now has a <code class="docutils literal notranslate"><span class="pre">--no-tree</span></code> 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 <code class="docutils literal notranslate"><span class="pre">bzr+ssh://</span></code> to the user when they
use <a class="reference external" href="ssh://">ssh://</a>. (Jelmer Vernooij, #330535)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">-v</span> <span class="pre">info</span></code> now omits the number of committers branch statistic,
making it many times faster for large projects. To include that
statistic in the output, use <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">-vv</span> <span class="pre">info</span></code>.
(Ian Clatworthy)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">push</span></code> to a <code class="docutils literal notranslate"><span class="pre">bzr</span></code> url (<code class="docutils literal notranslate"><span class="pre">bzr://</span></code>, <code class="docutils literal notranslate"><span class="pre">bzr+ssh://</span></code> 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 <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">shelve</span></code> prompt now includes a ‘?’ help option to explain the
short options better. (Daniel Watkins, #327429)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">lp-open</span></code> now falls back to the push location if it cannot find a
public location. (Jonathan Lange, #332372)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">lp-open</span></code> will try to find the Launchpad URL for the location
passed on the command line. This makes <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">lp-open</span> <span class="pre">lp:foo</span></code> work as
expected. (Jonathan Lange, #332705)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">send</span></code> now supports MH-E via <code class="docutils literal notranslate"><span class="pre">emacsclient</span></code>. (Eric Gillespie)</li>

<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">shelve</span></code> now properly handle patches with no terminating newline.

<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">unshelve</span></code> 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.

<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 <code class="docutils literal notranslate"><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></code> less chatty.
(Kent Gibson, #221461)</li>
<li>Many Branch hooks would not fire with <code class="docutils literal notranslate"><span class="pre">bzr://</span></code> and <code class="docutils literal notranslate"><span class="pre">bzr+ssh://</span></code>
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,
#334808)</li>
<li><code class="docutils literal notranslate"><span class="pre">setup.py</span> <span class="pre">build_ext</span></code> 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.

<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">selftest</span></code> now fails if the bazaar sources contain trailing
whitespace, non-unix style line endings and files not ending in a

updated to comply with this. The code already complied with the other
criteria, but now it is enforced. (Marius Kruger)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.branch.PushResult</span></code> was renamed to

than a count of copied revisions and failed revisions. A while back
we stopped ever reporting failed revisions because we started

UI at all - indeed it only reflects the repository status not
changes to the branch itself. (Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">Inventory.apply_delta</span></code> now raises an AssertionError if a file-id

<li>Revision.get_apparent_author() is now deprecated, replaced by
Revision.get_apparent_authors(), which returns a list. The former

<h3>Internals<a class="headerlink" href="#internals" title="Permalink to this headline">¶</a></h3>
<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><code class="docutils literal notranslate"><span class="pre">Branch.clone</span></code> now takes the <code class="docutils literal notranslate"><span class="pre">repository_policy</span></code> formerly used
inside <code class="docutils literal notranslate"><span class="pre">BzrDir.clone_on_transport</span></code>, allowing stacking to be
configured before the branch tags and revision tip are set. This

plugins to have hooks called on non-stacked instances.
(Robert Collins, #334187)</li>

<li><code class="docutils literal notranslate"><span class="pre">BzrDirFormat.__str__</span></code> now uses the human readable description
rather than the sometimes-absent disk label. (Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.fetch</span></code> 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><code class="docutils literal notranslate"><span class="pre">bzrlib.tests.run_suite</span></code> 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 <code class="docutils literal notranslate"><span class="pre">intern()</span></code>, 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 <code class="docutils literal notranslate"><span class="pre">create_clone_on_transport</span></code> 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 <code class="docutils literal notranslate"><span class="pre">BzrDir.find_repository</span></code> verb supporting

with pack repositories. (Andrew Bennetts, Robert Collins)</li>

now have a <code class="docutils literal notranslate"><span class="pre">network_name</span></code> for passing the format across RPC calls.
(Robert Collins, Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">RepositoryFormat</span></code> objects now all have a new attribute
<code class="docutils literal notranslate"><span class="pre">_serializer</span></code> used by fetch when reserialising is required.
(Robert Collins, Andrew Bennetts)</li>
<li>Some methods have been pulled up from <code class="docutils literal notranslate"><span class="pre">BzrBranch</span></code> to <code class="docutils literal notranslate"><span class="pre">Branch</span></code>
to aid branch types that are not bzr branch objects (like

use <code class="docutils literal notranslate"><span class="pre">multiply_tests</span></code>, or for lower level needs <code class="docutils literal notranslate"><span class="pre">apply_scenarios</span></code>
and <code class="docutils literal notranslate"><span class="pre">apply_scenario</span></code>. (Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">TestSkipped</span></code> is now detected by TestCase and passed to the
<code class="docutils literal notranslate"><span class="pre">TestResult</span></code> by calling <code class="docutils literal notranslate"><span class="pre">addSkip</span></code>. For older TestResult objects,
where <code class="docutils literal notranslate"><span class="pre">addSkip</span></code> is not available, <code class="docutils literal notranslate"><span class="pre">addError</span></code> 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 <code class="docutils literal notranslate"><span class="pre">_index</span></code> of <code class="docutils literal notranslate"><span class="pre">KnitVersionedFiles</span></code> now supports the ability
to scan an underlying index that is going to be incorporated into
the <code class="docutils literal notranslate"><span class="pre">KnitVersionedFiles</span></code> object, to determine if it has missing
delta references. The method is <code class="docutils literal notranslate"><span class="pre">scan_unvalidated_index</span></code>.
(Andrew Bennetts, Robert Collins)</li>
<li>There is a RemoteSink object which handles pushing to smart servers.
(Andrew Bennetts, Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">TransportTraceDecorator</span></code> now logs <code class="docutils literal notranslate"><span class="pre">put_bytes_non_atomic</span></code> and
<code class="docutils literal notranslate"><span class="pre">rmdir</span></code> calls. (Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">VersionedFiles</span></code> record adapters have had their signature change
from <code class="docutils literal notranslate"><span class="pre">(record,</span> <span class="pre">record.get_bytes_as(record.storage_kind))</span></code> to
<code class="docutils literal notranslate"><span class="pre">(record)</span></code> 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.
