Notes When Upgrading
25
********************
26
27
* Fetching via the smart protocol may need to reconnect once during a fetch
28
  if the remote server is running Bazaar 1.1 or earlier, because the client
29
  attempts to use more efficient requests that confuse older servers.  You
30
  may be required to re-enter a password or passphrase when this happens.
31
  This won't happen if the server is upgraded to Bazaar 1.2.
32
  (Andrew Bennetts)

Changes
35
*******
36
37
* Fetching via bzr+ssh will no longer fill ghosts by default (this is
38
  consistent with pack-0.92 fetching over SFTP). (Robert Collins)
39
40
* Formatting of ``bzr plugins`` output is changed to be more human-
41
  friendly. Full path of plugins locations will be shown only with
42
  ``--verbose`` command-line option. (Alexander Belchenko)
43
44
* ``merge`` now prefers to use the submit branch, but will fall back to
45
  parent branch.  For many users, this has no effect.  But some users who
46
  pull and merge on the same branch will notice a change.  This change
47
  makes it easier to work on a branch on two different machines, pulling
48
  between the machines, while merging from the upstream.
49
  ``merge --remember`` can now be used to set the submit_branch.
50
  (Aaron Bentley)
51
52
Features
53
********
54
55
* ``merge --preview`` produces a diff of the changes merge would make,
56
  but does not actually perform the merge.  (Aaron Bentley)
57
58
* New smart method ``Repository.get_parent_map`` for getting revision
59
  parent data. This returns additional parent information topologically
60
  adjacent to the requested data to reduce round trip latency impacts.
61
  (Robert Collins)
62
63
* New smart method, ``Repository.stream_revisions_chunked``, for fetching
64
  revision data that streams revision data via a chunked encoding.  This
65
  avoids buffering large amounts of revision data on the server and on the
66
  client, and sends less data to the server to request the revisions.
67
  (Andrew Bennetts, Robert Collins, #178353)
68
69
* The launchpad plugin now handles lp urls of the form
70
  ``lp://staging/``, ``lp://demo/``, ``lp://dev/`` to use the appropriate
71
  launchpad instance to do the resolution of the branch identities.
72
  This is primarily of use to Launchpad developers, but can also
73
  be used by other users who want to try out Launchpad as
74
  a branch location without messing up their public Launchpad
75
  account.  Branches that are pushed to the staging environment
76
  have an expected lifetime of one day. (Tim Penhey)
77

Improvements
79
************
80
81
* Creating a new branch no longer tries to read the entire revision-history
82
  unnecessarily over smart server operations. (Robert Collins)
83
84
* Fetching between different repository formats with compatible models now
85
  takes advantage of the smart method to stream revisions.  (Andrew Bennetts)
86
87
* The ``--coverage`` option is now global, rather specific to ``bzr
88
  selftest``.  (Andrew Bennetts)
89
90
* The ``register-branch`` command will now use the public url of the branch
91
  containing the current directory, if one has been set and no explicit
92
  branch is provided.  (Robert Collins)
93
94
* Tweak the ``reannotate`` code path to optimize the 2-parent case.
95
  Speeds up ``bzr annotate`` with a pack repository by approx 3:2.
96
  (John Arbash Meinel)

Bugfixes
99
********
100
101
* Calculate remote path relative to the shared medium in _SmartClient.  This
102
  is related to the problem in bug #124089.  (Andrew Bennetts)
103
104
* Cleanly handle connection errors in smart protocol version two, the same
105
  way as they are handled by version one.  (Andrew Bennetts)
106
107
* Clearer error when ``version-info --custom`` is used without
108
  ``--template`` (Lukáš Lalinský)
109
110
* Don't raise UnavailableFeature during test setup when medusa is not
111
  available or tearDown is never called leading to nasty side effects.
112
  (#137823, Vincent Ladeuil)
113
114
* If a plugin's test suite cannot be loaded, for example because of a syntax
115
  error in the tests, then ``selftest`` fails, rather than just printing
116
  a warning.  (Martin Pool, #189771)
117
118
* List possible values for BZR_SSH environment variable in env-variables
119
  help topic. (Alexander Belchenko, #181842)
120
121
* New methods ``push_log_file`` and ``pop_log_file`` to intercept messages:
122
  popping the log redirection now precisely restores the previous state,
123
  which makes it easier to use bzr log output from other programs.
124
  TestCaseInTempDir no longer depends on a log redirection being established
125
  by the test framework, which lets bzr tests cleanly run from a normal
126
  unittest runner.
127
  (#124153, #124849, Martin Pool, Jonathan Lange)
128
129
* ``pull --quiet`` is now more quiet, in particular a message is no longer
130
  printed when the remembered pull location is used. (James Westby,
131
  #185907)
132
133
* ``reconfigure`` can safely be interrupted while fetching.
134
  (Aaron Bentley, #179316)
135
136
* ``reconfigure`` preserves tags when converting to and from lightweight
137
  checkouts.  (Aaron Bentley, #182040)
138
139
* Stop polluting /tmp when running selftest.
140
  (Vincent Ladeuil, #123363)
141
142
* Switch from NFKC => NFC for normalization checks. NFC allows a few
143
  more characters which should be considered valid.
144
  (John Arbash Meinel, #185458)
145
146
* The launchpad plugin now uses the ``edge`` xmlrpc server to avoid
147
  interacting badly with a bug on the launchpad side. (Robert Collins)
148
149
* Unknown hostnames when connecting to a ``bzr://`` URL no longer cause
150
  tracebacks.  (Andrew Bennetts, #182849)
151
152
API Breaks
153
**********
154
155
* Classes implementing Merge types like Merge3Merger must now accept (and
156
  honour) a do_merge flag in their constructor.  (Aaron Bentley)
157
158
* ``Repository.add_inventory`` and ``add_revision`` now require the caller
159
  to previously take a write lock (and start a write group.)
160
  (Martin Pool)
161
162
Testing
163
*******
164
165
* selftest now accepts --load-list <file> to load a test id list. This
166
  speeds up running the test suite on a limited set of tests.
167
  (Vincent Ladeuil)
168
169
Internals
170
*********
171
172
* Add a new method ``get_result`` to graph search objects. The resulting
173
  ``SearchResult`` can be used to recreate the search later, which will
174
  be useful in reducing network traffic. (Robert Collins)
175
176
* Use convenience function to check whether two repository handles
177
  are referring to the same repository in ``Repository.get_graph``.
178
  (Jelmer Vernooij, #187162)
179
180
* Fetching now passes the find_ghosts flag through to the
181
  ``InterRepository.missing_revision_ids`` call consistently for all
182
  repository types. This will enable faster missing revision discovery with
183
  bzr+ssh. (Robert Collins)
184
185
* Fix error handling in Repository.insert_data_stream. (Lukas Lalinsky)
186
187
* ``InterRepository.missing_revision_ids`` is now deprecated in favour of
188
  ``InterRepository.search_missing_revision_ids`` which returns a
189
  ``bzrlib.graph.SearchResult`` suitable for making requests from the smart
190
  server. (Robert Collins)
191
192
* New error ``NoPublicBranch`` for commands that need a public branch to
193
  operate. (Robert Collins)
194
195
* New method ``iter_inventories`` on Repository for access to many
196
  inventories. This is primarily used by the ``revision_trees`` method, as
197
  direct access to inventories is discouraged. (Robert Collins)
198
199
* New method ``next_with_ghosts`` on the Graph breadth-first-search objects
200
  which will split out ghosts and present parents into two separate sets,
201
  useful for code which needs to be aware of ghosts (e.g. fetching data
202
  cares about ghosts during revision selection). (Robert Collins)
203
204
* Record a timestamp against each mutter to the trace file, relative to the
205
  first import of bzrlib.  (Andrew Bennetts)
206
207
* ``Repository.get_data_stream`` is now deprecated in favour of
208
  ``Repository.get_data_stream_for_search`` which allows less network
209
  traffic when requesting data streams over a smart server. (Robert Collins)
210
211
* ``RemoteBzrDir._get_tree_branch`` no longer triggers ``_ensure_real``,
212
  removing one round trip on many network operations. (Robert Collins)
213
214
* RemoteTransport's ``recommended_page_size`` method now returns 64k, like
215
  SFTPTransport and HttpTransportBase.  (Andrew Bennetts)
216
217
* Repository has a new method ``has_revisions`` which signals the presence
218
  of many revisions by returning a set of the revisions listed which are
219
  present. This can be done by index queries without reading data for parent
220
  revision names etc. (Robert Collins)
