This release of Bazaar adds a new repository format, ``1.9``, with smaller
14
and more efficient index files. This format can be specified when
15
creating a new repository, or used to losslessly upgrade an existing
16
repository. bzr 1.9 also speeds most operations over the smart server
17
protocol, makes annotate faster, and uses less memory when making
18
checkouts or pulling large amounts of data.
23
* Fix "invalid property value 'branch-nick' for None" regression with
24
branches bound to svn branches. (Martin Pool, #293440)
26
* Fix SSL/https on Python2.6. (Vincent Ladeuil, #293054)
28
* ``SFTPTransport.readv()`` had a bug when requests were out-of-order.
29
This only triggers some-of-the-time on Knit format repositories.
30
(John Arbash Meinel, #293746)
41
* New Branch hook ``transform_fallback_location`` allows a function to
42
be called when looking up the stacked source. (Michael Hudson)
44
* New repository formats ``1.9`` and ``1.9-rich-root``. These have all
45
the functionality of ``1.6``, but use the new btree indexes.
46
These indexes are both smaller and faster for access to historical
47
information. (John Arbash Meinel)
52
* ``BTreeIndex`` code now is able to prefetch extra pages to help tune
53
the tradeoff between bandwidth and latency. Should be tuned
54
appropriately to not impact commands which need minimal information,
55
but provide a significant boost to ones that need more context. Only
56
has a direct impact on the ``--development2`` format which uses
57
btree's for the indexes. (John Arbash Meinel)
59
* ``bzr dump-btree`` is a hidden command introduced to allow dumping
60
the contents of a compressed btree file. (John Arbash Meinel)
62
* ``bzr pack`` now tells the index builders to optimize for size. For
63
btree index repositories, this can save 25% of the index size
64
(mostly in the text indexes). (John Arbash Meinel)
66
* ``bzr push`` to an existing branch or repository on a smart server
67
is faster, due to Bazaar making more use of the ``get_parent_map``
68
RPC when querying the remote branch's revision graph.
71
* default username for bzr+ssh:// and sftp:// can be configured in
72
authentication.conf. (Aaron Bentley)
74
* launchpad-login now provides a default username for bzr+ssh and SFTP
75
URLs, allowing username-free URLs to work for everyone. (Aaron Bentley)
77
* ``lp:`` lookups no longer include usernames, making them shareable and
78
shorter. (Aaron Bentley)
80
* New ``PackRepository.autopack`` smart server RPC, which does
81
autopacking entirely on the server. This is much faster than
82
autopacking via plain file methods, which downloads a large amount
83
of pack data and then re-uploads the same pack data into a single
84
file. This fixes a major (although infrequent) cause of lengthy
85
delays when using a smart server. For example, pushing the 10th
86
revision to a repository with 9 packs now takes 44 RPCs rather than
87
179, and much less bandwidth too. This requires Bazaar 1.9 on both
88
the client and the server, otherwise the client will fallback to the
89
slower method. (Andrew Bennetts)
94
* A failure to load a plugin due to an IncompatibleAPI exception is
95
now correctly reported. (Robert Collins, #279451)
97
* API versioning support now has a multiple-version checking api
98
``require_any_api``. (Robert Collins, #279447)
100
* ``bzr branch --stacked`` from a smart server to a standalone branch
101
works again. This fixes a regression in 1.7 and 1.8.
102
(Andrew Bennetts, #270397)
104
* ``bzr co`` uses less memory. It used to unpack the entire WT into
105
memory before writing it to disk. This was a little bit faster, but
106
consumed lots of memory. (John Arbash Meinel, #269456)
108
* ``bzr missing --quiet`` no longer prints messages about whether
109
there are missing revisions. The exit code indicates whether there
110
were or not. (Martin Pool, #284748)
112
* Fixes to the ``annotate`` code. The fast-path which re-used the
113
stored deltas was accidentally disabled all the time, instead of
114
only when a branch was stacked. Second, the code would accidentally
115
re-use a delta even if it wasn't against the left-parent, this
116
could only happen if ``bzr reconcile`` decided that the parent
117
ordering was incorrect in the file graph. (John Arbash Meinel)
119
* "Permission denied" errors that occur when pushing a new branch to a
120
smart server no longer cause tracebacks. (Andrew Bennetts, #278673)
122
* Some compatibility fixes for building the extensions with MSVC and
123
for python2.4. (John Arbash Meinel, #277484)
125
* The index logic is now able to reload the list of pack files if and
126
index ends up disappearing. We still don't reload if the pack data
127
itself goes missing after checking the index. This bug appears as a
128
transient failure (file not found) when another process is writing
129
to the repository. (John Arbash Meinel, #153786)
131
* ``bzr switch`` and ``bzr bind`` will now update the branch nickname if
132
it was previously set. All checkouts will now refer to the bound branch
133
for a nickname if one was not explicitly set.
134
(Marius Kruger, #230903)
139
* Improved hook documentation. (Michael Ernst)
144
* commands.plugins_cmds is now a CommandRegistry, not a dict.
149
* New AuthenticationConfig.set_credentials method allows easy programmatic
150
configuration of authetication credentials.
