<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>

<h3>Bug Fixes<a class="headerlink" href="#id1" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">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
repository that supported subtrees, even though the local one would
not. We deprecated that format, and introduced a new one that uses
the correct serializer <tt class="docutils literal"><span class="pre">--1.6.1-rich-root</span></tt>.

<p>Finally, the long awaited bzr 1.6 has been released. This release includes
new features like Stacked Branches, improved weave merge, and an updated
server protocol (now on v3) which will allow for better cross version
compatibility. With this release we have deprecated Knit format
repositories, and recommend that users upgrade them, we will continue to
support reading and writing them for the forseeable future, but we will
not be tuning them for performance as pack repositories have proven to be
better at scaling. This will also be the first release to bundle
TortoiseBzr in the standalone Windows installer.</p>

<p>This release candidate for bzr 1.6 solidifies the new branch stacking
feature. Bazaar now recommends that users upgrade all knit repositories,
because later formats are much faster. However, we plan to continue read/write and
upgrade support for knit repostories for the forseeable future. Several
other bugs and performance issues were fixed.</p>

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

<p>Commands that work on the revision history such as push, pull, missing,

other translations would be very welcome.) Bazaar 1.6beta1 adds a new network
protocol which is used by default and which allows for more efficient transfers
and future extensions.</p>

<h3>Notes When Upgrading<a class="headerlink" href="#notes-when-upgrading" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>There is a new version of the network protocol used for bzr://, bzr+ssh://
and bzr+http:// connections. This will allow more efficient requests and
responses, and more graceful fallback when a server is too old to
recognise a request from a more recent client. Bazaar 1.6 will
interoperate with 0.16 and later versions, but servers should be upgraded
when possible. Bazaar 1.6 no longer interoperates with 0.15 and earlier via
these protocols. Use alternatives like SFTP or upgrade those servers.

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">RevisionSpec.wants_revision_history</span></tt> can be set to False for a given

<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

<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.
