Bazaar Release Notes¶
bzr 2.5.2¶
- 2.5.2
NOT RELEASED YET
External Compatibility Breaks¶
New Features¶
Improvements¶
Bug Fixes¶
bzr configproperly handles aliases and references in the--directoryparameter (Vincent Ladeuil, Wouter van Heyst, #947049)Empty arguments in EDITOR are now properly preserved. (Ross Lagerwall, #1089792)
Fix a traceback when trying to checkout a tree that also has an entry with file-id TREE_ROOT somewhere other than at the root directory. (John Arbash Meinel, #830947)
Lightweight checkouts of remote repositories had a bug with how they extracted texts from the repository. (Just an ordering constraint on how they consumed the stream.) (John Arbash Meinel, #1046284)
osutils.send_allnow detects if we get a series of zero bytes sent, and fails with a ECONNRESET. It seems if paramiko gets disconnected, it will get into a state where it returns 0 bytes sent, but doesn’t raise an error. This change allows us to get a couple hiccups of no content sent, but if it is consistent, we will consider it to be a failure. (John Arbash Meinel, #1047309)Revert use of –no-tty when gpg signing commits. (Jelmer Vernooij, #1014570)
Some filesystems give
EOPNOTSUPPwhen trying to callfdatasync. This shouldn’t be treated as a fatal error. (John Arbash Meinel, #1075108)Some small bug fixes wrt lightweight checkouts and remote repositories. A test permutation was added that runs all working tree tests against a lightweight checkout. (John Arbash Meinel, #1046697)

External Compatibility Breaks¶
None.
New Features¶
None.
Improvements¶
bzr rmbranchnow supports removing colocated branches. (Jelmer Vernooij, #920653)bzr rmbranchno longer removes active branches unless--forceis specified. (Jelmer Vernooij, #922953)
Bug Fixes¶
Connecting with HTTPS via HTTP now correctly uses the host name of the destination rather than the proxy when checking certificates. (Martin Packman, #944696)

bzr 2.5.0¶
- Codename
Phillip
- 2.5.0
2012-02-24
This release marks the start of a new long-term-stable series. From here, we will only make bugfix releases on the 2.5 series (2.5.1, etc, and support it until April 2017), while 2.6 will become our new development series.
This is a bugfix and polish release over the 2.4 series, with a large number of bugs fixed (~170 for the 2.5 series alone). The 2.5 series provides a faster smart protocol implementation for many operations, basic support for colocated branches. We have started translating bzr with the 2.5 series: https://translations.launchpad.net/bzr, more than 20 languages have already been registered but these are the early days, contributions welcome.
Only a few bugfixes have been included since 2.5b6 so all known fixed bugs are included here.
Users are encouraged to upgrade from the other stable series.
External Compatibility Breaks¶
None.
New Features¶
None.
Improvements¶
The names of colocated branches are used as branch nicks if no nick is specified. (Aaron Bentley)
Bug Fixes¶
Show locks in
bzr infoon control directories without a repository. (Jelmer Vernooij, #936767)Disable ssl certificate verification on osx and windows until a native access to the the root certificates is provided there. (Vincent Ladeuil, #929179)

- 2.5b6
2012-02-02
This is the sixth (and last (really)) beta of the 2.5 series, leading to a 2.5.0 release in March 2012. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins.
This introduces the support for colocated branches into the ‘2a’ format in a backward compatible way, fix more glitches in the colocated UI, verify https certificates for the urllib https client implementation, fix some more unicode issues and more.
All bugs fixed in previous series known at the time of this release are included.
External Compatibility Breaks¶
None.
New Features¶
Support for colocated branches is now available in the default format (“2a”). (Jelmer Vernooij)
Improvements¶
bzr switch -bin a standalone tree will now create a colocated branch. (Jelmer Vernooij, #918197)bzr infonow reports when there are present (but unused) colocated branches. (Jelmer Vernooij, #891646)Checkouts can now be into target directories that already have a control directory (but no branch or working tree). (Jelmer Vernooij, #913980)
Colocated branches can now have names including forward slashes, to allow for namespaces. (Jelmer Vernooij, #907980)
New HPSS call for
BzrDir.get_branches. (Jelmer Vernooij, #894460)Checkouts of colocated branches are now always lightweight. (Jelmer Vernooij, #918828)
Bug Fixes¶
bzr branchnow fetches revisions when branching into an empty control directory. (Jelmer Vernooij, #905594)A sane default is provided for
ssl.ca_certswhich should points to the Certificate Authority bundle for supported platforms. (Vincent Ladeuil, #920455)bzr branchgenerates correct target branch locations again if not specified. (Jelmer Vernooij, #919218)bzr sendworks on treeless branches again. (Jelmer Vernooij, #921591)bzr versionno longer throws a UnicodeDecodeError if the .bzr.log path contains non-ascii characters. (Martin Packman, #312841)Support scripts that don’t call bzrlib.initialize() but still call run_bzr(). (Vincent Ladeuil, #917733)
Test for equality instead of object identity where ROOT_PARENT is concerned. (Wouter van Heyst, #881142)
urllib-based HTTPS client connections now verify the server certificate validity as well as the hostname. (Jelmer Vernooij, Vincent Ladeuil, #651161)
API Changes¶

bzr 2.5b5¶
- 2.5b5
2012-01-12
This is the fifth (and last) beta of the 2.5 series, leading to a 2.5.0 release in February 2012. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins.
This release includes many improvements in the smart server, UI polish for the colocated branches, enhancements to the config framework and more internal uses, bug fixes related to unicode and locale support and more.
All bug fixed in previous series known at the time of this release are included.
External Compatibility Breaks¶
The ‘.bzr/branch/email’ file is no longer read to determine the users’ identity. Instead, the ‘email’ setting in ‘.bzr/branch/branch.conf’ should be used. (Jelmer Vernooij, #903894)
New Features¶
“bzr mkdir” now includes -p (–parents) option for recursively adding parent directories. (Jared Hance, Jelmer Vernooij, #253529)
config.Optioncan now declareoverride_from_env, a list of environment variables which, when set, that takes precedence over values defined in configuration files. (Vincent Ladeuil, #907279)
Improvements¶
New HPSS call for
Repository.reconcile. (Jelmer Vernooij, #894455)Merge now has two new hooks
pre_mergeandpost_mergethat are called before and after a merge and can make additional modifications to the trees involved. (Jelmer Vernooij, #906877)Override the value returned by
sys.getfilesystemencoding()for the bzr script to utf-8 when it would otherwise be ascii on a posix system. This will mean bzr works with non-ascii files when no locale or an incorrect locale is set. (Martin Packman, #794353)bzr branchesnow indicates the active colocated branch. (Jelmer Vernooij, #891667)bzr pushnow suggests using :parent if there is a parent location set. (Jelmer Vernooij)bzr sendnow only opens a single connection, rather than two, to the target branch. (Jelmer Vernooij)
Bug Fixes¶
Allow configuration option default value to be a python callable at registration. (Vincent Ladeuil, #832064)
bzr configwill now display the section[DEFAULT]used inbazaar.conf. (Vincent Ladeuil, #907268)Configuration stores can now provides a specific quoting mechanism. This is required to workaround
configobjconflating quoting and list values automatic conversion. (Vincent Ladeuil, #906897)Create obsolete_packs directory when repacking if it does not exist. (Jonathan Riddell, Jelmer Vernooij, #314314)
Fallback to the slower
bzr logimplementation when displaying a range of revisions whose ancestry is not obviously on the same developement line. (Vincent Ladeuil, #904744)Make lazy imports resilient when resolved concurrently from multiple threads. Now the stand-in object will behave as a proxy for the real object after the initial access, rather than throwing. Assigning the object to multiple names should still be avoided. (Martin von Gagern, #396819)
Not setting
gpg_signing_keyor setting it todefaultwill use the user email (obtained from theemailconfiguration option or its default value). (Vincent Ladeuil, Jelmer Vernooij, #904550)Prevent spurious InconsistentDelta error when committing a move of a non-ascii directory with contents. (Rory Yorke, #185211)
Properly ignore ‘n’ in an option reference since this cannot be part of a config option identifier. (Vincent Ladeuil, #902125)
Make sure that the bzr probers are always registered when bzrlib.workingtree is imported. (Jelmer Vernooij, #905218)
Report mistake trying to move a removed file with a non-ascii name without UnicodeEncodeError being raised. (Martin Packman, #898541)
Safely unquote configuration values in weird edge cases (a section seen as a dictionary which is not a supported use case for the configuration stacks). (Vincent Ladeuil, #908050)
Stop altering
sys.platformon OSX when initialising the locale. (Martin Packman, #570495)Uncommit no longer removes tags if they are part of the working trees pending merges. (Jelmer Vernooij, #905462)
API Changes¶
Config.signature_needed,Config.signing_policy,Config.gpg_signing_key,Config.gpg_signing_command,Config.checking_policyandConfig.post_commitare now deprecated. (Jelmer Vernooij)Repository.get_commit_buildernow takes aconfig_stackrather than aconfigargument. (Jelmer Vernooij)Scripts using bzrlib should now ensure setlocale is called on posix platforms if they need a non-ascii user encoding. (Martin Packman)
Send formats now accept a new optional argument
submit_branch, which can be None or a Branch object for the submit branch location. (Jelmer Vernooij)VersionedFileRepository.add_revisionno longer takes aconfigargument. (Jelmer Vernooij)
Internals¶
Add HPSS call for
Branch.get_checkout_format. (Jelmer Vernooij, #894459)Add HPSS call for
Repository.pack. (Jelmer Vernooij, #894461)Add HPSS calls for
Repository.iter_files_bytes, speeding up several commands includingbzr exportandbzr co --lightweight. (Jelmer Vernooij, #608640)All bzr control directories, branch formats, repository formats and working tree formats now support feature flags, which are serialized in their respective format files. See
doc/developers/feature-flags.txtfor details. (Jelmer Vernooij)bzrlib.urlutilsnow includesquoteandunquotefunctions, rather than importing them fromurllib. This prevents loading of thesocket,sslandurllibmodules for local bzr operations. (Jelmer Vernooij)Configuration options can be SI units by using
int_SI_from_unicodeas theirconvert_from_unicodehelper. (Vincent Ladeuil)Configuration stacks can now use
StartingPathMatcherto select the sections matching a location while respecting the order chosen by the user in the configuration file: from generic sections to specific sections. (Vincent Ladeuil, #832046).Configuration stores can now save incremental changes by using
save_changes()instead ofsave(). This reduces the number or required input/outputs and allows stores to be shared between stacks. (Vincent Ladeuil)ControlDir now has a get_branches method that returns a dictionary whose keys are the names of the branches and whose values are the branches themselves. The active branch uses the key None. (Neil Martinsen-Burrell)
Helper
osutils.path_from_environadded for extracting a unicode path from an environment variable. (Martin Packman, #832028)Helper
win32utils.get_environ_unicodeadded for avoiding encoding problems withos.environ.getuse. (Martin Packman, #262874)Lazy imports can now only be absolute. (Jelmer Vernooij)
Merge3Mergers now have an optional
other_branchargument which contains the branch from which theother_treewas obtained, if any. (Jelmer Vernooij)MutableTree now has a hook
post_build_treewhich is called after a new mutable tree has been created. (Jelmer Vernooij, #912765)New HPSS call
BzrDir.checkout_metadir. (Jelmer Vernooij, #894459)New HPSS call
VersionedFileRepository.get_inventories, speeding up various commands includingbzr export,bzr checkoutandbzr cat. (Jelmer Vernooij, #608640)The
ConfigCommandLineStoreis now supported bybzr configand is seen as single no-name section of configuration options. (Vincent Ladeuil)
Testing¶
New matcher
ContainsNoVfsCallswhich filters a list of HPSS calls for VFS requests. (Jelmer Vernooij)New
MemoryStackclass allows for diskless tests and locally injected configuration stacks. Lower level tests for predefined set of options can be written without setting up configuration files. (Vincent Ladeuil)
bzr 2.5b4¶
- 2.5b4
2011-12-08
This is the fourth beta of the 2.5 series, leading to a 2.5.0 release in February 2012. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins.

All bug fixed in previous series known at the time of this release are included.
External Compatibility Breaks¶
None.
New Features¶
Provides a
po_mergeplugin to automatically merge.pofiles withmsgmerge. Seebzr help po_mergefor details. (Vincent Ladeuil, #884270)
Improvements¶
bzr branch --stackednow only makes a single connection to the remote server rather than three. (Jelmer Vernooij, #444293)bzr export --uncommittedwill export the uncommitted tree. (Jelmer Vernooij, #555613)bzr rmbranchcan now remove colocated branches. (Jelmer Vernooij, #831464)bzr statusno longer shows shelves if files are specified. (Francis Devereux)bzr switchnow accepts colocated branch names to switch to. (Jelmer Vernooij, #826814)Plugins can now register additional “location aliases”. (Jelmer Vernooij)
Revision specifiers will now only browse as much history as they need to, rather than grabbing the whole history unnecessarily in some cases. (Jelmer Vernooij)
When using
bzr switchto switch to a sibling of the current branch, the relative branch name should no longer be url-encoded. (Jelmer Vernooij)
Bug Fixes¶
A new section local option
basenameis available to help support somebzr-pipelineworkflows and more generally help mapping local paths to remote ones. Seebzr help configurationfor more details. (Vincent Ladeuil, #843211)Add HPSS call for looking up revision numbers from revision ids on remote repositories. (Jelmer Vernooij, #640253)
Add HPSS call for retrieving file contents from remote repositories. Should improve performance for lightweight checkouts and exports of from remote repositories. (Jelmer Vernooij, #368717, #762330, #608640)

bzrlib.lazy_regexto be pickled. (Jelmer Vernooij, #893149)bzr infono longer shows empty output if only a control directory is present. (Jelmer Vernooij, #159098)Cope with missing revision ids being specified to
Repository.gather_statsHPSS call. (Jelmer Vernooij, #411290)Fix test failures on windows related to locations.conf handling. (Vincent Ladeuil, #892992)
Fixed parsing of the timestamp given to
commit --commit-time. Now prohibits several invalid strings, reads the correct number of seconds, and gives a better error message if the time zone offset is not given. (Matt Giuca, #892657)Give meaningful file/line references when reporting deprecation warnings for _CompatabilityThunkFeature based test features. (Vincent Ladeuil, #897718)

Support verifying signatures on remote repositories. (Jelmer Vernooij, #889694)
Teach the bzr client how to reconnect if we get
ConnectionResetwhile making an RPC request. This doesn’t handle all possible network disconnects, but it should at least handle when the server is asked to shutdown gracefully.

dialogs, enhancements to the config framework and more.
This release includes all bug fixed in previous series known at the time of this release.
External Compatibility Breaks¶
None
New Features¶
The
log_formatconfiguration can be used with-Olog_format=lineto change the formatpushandpulluse to display the revisions. I.e.:bzr pull -v -Olog_format=shortwill use theshortformat instead of the defaultlongone. (Vincent Ladeuil, #861472)The new config scheme allows an alternative syntax for the ‘appenpath’ policy relying on option expansion and defining a new ‘relpath’ option local to a section. Instead of using ‘<option>:policy=appendpath’, the option value can de defined as ‘option=xxxx/{relpath}’. (Vincent Ladeuil, #832013)
Improvements¶
bzr info -vnow shows the number of colocated branches for control directories that support them. (Jelmer Vernooij, #863285)bzr version-infonow takes a--revisionargument. (Jelmer Vernooij, #238705)bzr revnonow takes a--revisionargument. (Jelmer Vernooij, #870649)bzr servenow can serve from URLs rather than just from the file system. I.e.:bzr serve -d lp:bzrorbzr serve -d file:///data/bzr(Jelmer Vernooij)all input prompts are now char-based when possible, and can be forced to line-based mode by setting the
BZR_TEXTUI_INPUTenvironment variable to ‘line-based’. This replace the previous shelf UI only patch usingINSIDE_EMACS. (Benoît Pierre)
Bug Fixes¶
bzr infonow shows the master branch location too for treeless local branches. (Jelmer Vernooij, #258355)bzr mkdir --quietnow does not print a line for every created directory. (Martin von Gagern, #869915)bzr mvdoes not crash when attempting to move the root of a branch. (Jonathan Riddell, #809728)bzr shelvenow useUIFactory.choosefor input handling, making it usable when creating a customUIFactoryimplementation. (Benoît Pierre)bzr clean-treenow useUIFactory.get_booleanfor confirmation prompt, making it usable when using a customUIFactoryimplementation. (Benoît Pierre)If sending a crash through Apport fails report the Apport failure to bzr.log rather than stderr. (Jonathan Riddell, #766735)
bzr upgradeno longer treats ‘already up-to-date’ exceptions as errors. (Benoît Pierre, #716560).bzr version-infono longer populates the clean state for custom templates unless {clean} is explicitly asked for. (Lawrence Mitchell, #882541)Fix finding the CPU count when using Python >= 2.6 on BSD-based systems. (Jelmer Vernooij, #887151)
WorkingTree.clone()now supports itsrevision_idbeing set to the null revision. (Jelmer Vernooij, #876423)WorkingTree.pullcan now pullNULL_REVISION. (Jelmer Vernooij, #887556)
API Changes¶
Branch.revision_historyis now deprecated. (Jelmer Vernooij, #799519)Methods
addanditemsofLRUCacheandLRUSizeCacheare deprecated. Use normal dict-style access instead. (Martin Packman)New flag
RepositoryFormat.supports_unreferenced_revisionswhich indicates whether revisions can be present in a repository without being referenced from e.g. a branch history at the same time. (Jelmer Vernooij)UIFactory.choosehas been added: prompt the user for a list of choices. (Benoît Pierre)
Internals¶
ControlDirFormatnow has a new methodsupports_transportwhich format implementations can use whether or not they can access a control dir over a particular transport. (Jelmer Vernooij)BranchBuilder.build_commitnow takeparent_idsandallow_leftmost_as_ghostarguments. (Jelmer Vernooij)
Testing¶
Ensure TestCase instances are deallocated immediately after running where possible. This greatly reduces the peak resource needs of a full test suite run. The new
-Euncollected_casesselftest flag will add failures if any case which persists pasts its expected lifetime. (Martin Packman, #613247)Report exceptions from child processes during fork instead of swallowing the error and reporting that everything went okay. (Martin Packman, #804130)
bzr 2.5b2¶
This is the second beta of the 2.5 series, leading to a 2.5.0 release in February 2012. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins.
This release includes more filtering options for bzr log, idle
connections handling for bzr serve, a development-colo experimental
format to flesh out the colocated branches UI, better support for foreign
formats, enhancements to the config framework and more.
This release includes all bug fixed in previous series known at the time of this release.
- 2.5b2
2011-10-06
External Compatibility Breaks¶
None
New Features¶
A new
-Ostandard option (common to all commands) have been added. It provides a value for a config option in the-Oname=valueform that takes precedence over all definitions found in config files. It can be used multiple times to override different options. (Vincent Ladeuil, #491196)bzr lognow has an option called--omit-mergesto omit those commits that merged branches, i.e. those having more than one parent. In order to avoid confusion, the previous command line option--include-mergeshas been renamed to--include-merged. The old name of the command line option will still be accepted. The name change also affectsbzr missing. (Martin von Gagern)bzr servewill now disconnect clients if they have not issued an RPC request after 5minutes. On POSIX platforms, this will also happen forbzr serve --inet. This can be overridden with the configuration variableserve.client_timeoutor in the command line parameterbzr serve --client-timeout=X. Further, it is possible to requestbzr serve [--inet]to shutdown gracefully by sending SIGHUP. It will finish the current request, and then close the connection. (John Arbash Meinel, #824797, #795025)The new experimental format
development-colosupports colocated branches. This format will eventually be merged back into the2aformat when it has stabilized and there is adequate UI support for colocated branches. (Jelmer Vernooij, #831481)
Improvements¶
Fixed a bug where
bzr tags -r x..yloaded the branch history once for every revision in the range; it’s now much faster. (Vincent Ladeuil, #857335)bzr info -vcan now be run against branches that don’t supportlast_revision_info, in which case the branch information will simply not be displayed. (Jelmer Vernooij)
Bug Fixes¶
bzr shelvecan now be used in emacs shells as the input handling is turned into a line-based one whenINSIDE_EMACSis set (which is the case for all recent emacs versions). (Vincent Ladeuil, #856261)bzr tagscan now be used against remote repositories that do not provide access to the revision graph. (Jelmer Vernooij, #858942)bzr update PATHwill stop if you seem to be asking it to update anything less than a whole tree, because that’s not supported bybzr’s concept that the whole tree has a single basis revision. Previously, it would go ahead and update the whole tree, which was surprising. (Martin Pool, #557886)Don’t crash if
bzrlib.initialize()has not been called while accessing configs. (Vincent Ladeuil, #863401)Redirects between http and https no longer discard path information in some cases. (Jelmer Vernooij, #853765)
The
--overwriteargument tobzr pushandbzr pullno longer reports all tags as changed. (Jelmer Vernooij, #845396)WorkingTree.get_file_mtimenow raises NoSuchId if a file id is specified that is unknown. (Jelmer Vernooij, #847435)
API Changes¶
Branch.get_revision_deltahas been deprecated. UseRepository.get_revision_deltainstead. (Jelmer Vernooij, #859712)Plugins that implement custom protocols for
bzr serveshould now also take an argumenttimeout. This is used by the the bzr protocol to close a connection if a client has been idle for more than X seconds. (Default 5minutes). (John Arbash Meinel)Repository.fileids_altered_by_revision_idshas been moved toVersionedFileRepositoryand is no longer part of the standardRepositoryinterface. (Jelmer Vernooij)The argument
include_mergestomissing.find_unmergedhas been renamed toinclude_merged. The old name is still supported for now but will cause a deprecation warning. (Martin von Gagern)The new method
ControlDirFormat.is_initializable()returns a boolean indicating whether or not it is possible to use any of the initialization methods of that format to create a new control dir. (Jelmer Vernooij)
Internals¶
Branchobjects can now use a config stack with the newly introducedget_config_stack(). Bothget_configandget_config_stackcan be used for the same branch but it’s recommended to stick to one for a given option.
Testing¶
Test scripts can now use
bzr shelveand provide their input as complete lines. (Vincent Ladeuil, #856261)Really corrupt the pack file without depending on a special length or value. (Vincent Ladeuil, #807032)
bzr 2.5b1¶
- 2.5b1
2011-09-15
This is the first beta of the 2.5 series, leading up to a 2.5.0 release in February 2012.
This release includes better support for gpg signing, better support for
i18n (mostly command help and error messages), more options to filter bzr
log output, more support for colocated branches (“location,branch=XXX”
syntax), better feedback on updated tags for various commands, faster
branching into an empty repository, enhancements to the config framework and
more.
Beta releases are suitable for everyday use but may cause some incompatibilities with plugins. Some plugins may need small updates to work with 2.5b1.
External Compatibility Breaks¶
None
New Features¶
A
from_unicodeparameter can be specified when registering a config option. This implements boolean, integer and list config options when the providedbool_from_store,int_from_storeandlist_from_storeare used for this parameter. (Vincent Ladeuil)Accessing a packaging branch on Launchpad (eg,
lp:ubuntu/bzr) now checks to see if the most recent published source package version for that project is present in the branch tags. This should help developers trust whether the packaging branch is up-to-date and can be used for new changes. The level of verbosity is controlled by the config itemlaunchpad.packaging_verbosity. It can be set to one of- off
disable all checks
- minimal
only display if the branch is out-of-date
- short
also display single-line up-to-date and missing,
- all
(default) display multi-line content for all states
(John Arbash Meinel, #609187, #812928)
Add a config option gpg_signing_key for setting which GPG key should be used to sign commits. Also default to using the gpg user identity which matches user_email() as set by whoami. (Jonathan Riddell, #68501)
An
invalidparameter can be specified when registering a config option to decide what should be done when invalid values are encountered. ‘warning’ and ‘error’ will respectively emit a warning and ignore the value or errors out. (Vincent Ladeuil)bzr add now skips large files in recursive mode. The default “large” size is 20MB, and is configurable via the add.maximum_file_size option. A value of 0 disables skipping. Named items passed to add are never skipped. (Shannon Weyrick, #54624)
bzr help configuration/<option>display the help foroptionfor all registered configuration options. (Vincent Ladeuil, #747050)bzr log -mnow matches message, author, committer and bugs instead of just matching the message.--messagekeeps its original meaning, while--match-message, --match-author, --match-committerand--match-bugsmatch each of those fields. (Jacek Sieka)config.Optioncan now declaredefault_from_env, a list of environment variables to get a default value from. (Vincent Ladeuil)config.NameMatchercan be used to implement config stores and stacks that need to provide specific option values for arbitrary unique IDs (svn repository UUIDs, etc). (Vincent Ladeuil, #843638)New builtin
bzr branchescommand, which lists all colocated branches in a directory. (Jelmer Vernooij, #826820)Relative local paths can now be specified in URL syntax by using the “file:” prefix. (Jelmer Vernooij)
Report commits signed with expired keys in
verify-signatures. (Jonathan Riddell, #804254)Translations are now enabled for command help, errors and globally for any message using
gettextgiven on output. (Jonathan Riddell, INADA Naoki, #83941)
Improvements¶
bzr addwill now warn about nested subtrees that are skipped. (Jelmer Vernooij, #187342)bzr commit -m ''can now be used to force an empty commit message. Entering an empty commit message in the message editor still triggers an error. (Jelmer Vernooij)bzr pullwill now mention how many tags it has updated. (Jelmer Vernooij, #164450)bzr tagno longer errors if a tag already exists but refers to the same revision, and will mention when a tag has been updated rather than created. (Jelmer Vernooij, #381203)bzr uncommitwill now remove tags that refer to removed revisions. The--keep-tagsoption can be used to prevent this behaviour. (Jelmer Vernooij, #605814)Do not run i18n initialisation twice. (Jonathan Riddell)
Install translation .mo files. (Jonathan Riddell)
Locations printed by
bzr upgradeare now formatted before display. (Jelmer Vernooij)Repository.get_parent_mapnow estimates the size of the returned content more accurately. This means that we get closer to the desired 64kB/request. For repositories converted from svn, this can be an improvement of approx 5:1 in round trips to discover the whole history. (John Arbash Meinel)Support a
bugtrackeroption which is used bybzr commit --fixesif no bug tracker was specified on the command line. (Jelmer Vernooij, #334860)Use
gettext.NullTranslationsin i18n to allow use of i18n even when translations are not turned on. (Jonathan Riddell)
Bug Fixes¶
bzr commitnow correctly reports missing files as “removed”, not “modified”. (Jelmer Vernooij, #553955)bzr reconfigurewill now allow multiple non-conflicting requests in a single invocation, e.g.--branchand--use-shared. (Martin von Gagern, #842993)A call to CHKInventory’s filter-method will not result in a DuplicateFileId error, if you move a subfolder and change a file in that subfolder. (Bastian Bowe, #809901)
Branching from a stacked branch no longer does a
get_parent_maprequest for each revisions that is in the stacked-on repository while determining what revisions need to be fetched. This mostly impacts branching initialy into an empty shared repository when the source is not the development focus. (John Arbash Meinel, #388269)Decode
BZR_HOMEwith fs encoding on posix platforms to avoid unicode errors. (Vincent Ladeuil, #822571)Fix fallout from URL handling changes in 2.5 that caused an IndexError to be raised whenever a transport at the drive root was opened on windows. (Martin [gz], #841322)
Fixed loading of external merge tools from config to properly decode command-lines which contain embedded quotes. (Gordon Tyler, #828803)
Rather than an error being raised, a warning is now printed when the current user does not have permission to read a configuration file. (Jelmer Vernooij, #837324)
The pull command will now always use separate connections for the case where the destination is a heavyweight checkout of some remote branch on the same host as the source branch. (Martin von Gagern, #483661)
TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so operations that use it, like merge, can now create trees without a root. (Aaron Bentley)
Documentation¶
Release instructions refreshed. (Vincent Ladeuil)
API Changes¶
BranchFormat.initializenow takes aappend_revisions_onlyargument. (Jelmer Vernooij)Branch._get_checkout_formatnow takes alightweightargument which indicates if the format should be for a lightweight or a heavyweight checkout. (Jelmer Vernooij)ControlDir.create_branchnow takes aappend_revisions_onlyargument. (Jelmer Vernooij)New class

Config.get_user_option_as_int_from_SIadded for expanding a value in SI format (i.e. “20MB”, “1GB”) into its integer equivalent. (Shannon Weyrick)New method
InterTree.file_content_matcheswhich checks that two files in different trees have the same contents. (Jelmer Vernooij)New method
Tree.get_file_verifierwhich allows tree implementations to return non-sha1 checksums to verify files. (Jelmer Vernooij, #720831)New methods
get_transport_from_pathandget_transport_from_urlhave been added that only support opening from a path or a URL, unlikeget_transport. (Jelmer Vernooij)New registry
OptionRegistryspecialized for configuration options. (Vincent Ladeuil)Remove
AtomicFile.closedwhich has been deprecated in bzr 0.10. (Vincent Ladeuil)Remove
commands._builtin_commands,commands.shlex_split_unicode,Command._maybe_expand_globsandCommand.run_directdeprecated in 2.10 and 2.2.0. (Vincent Ladeuil)Remove
diff.get_trees_and_branches_to_diffdeprecated in 2.2.0.Remove
log.calculate_view_revisions,log._filter_revision_range,log.get_view_revisionswhich have been deprecated in bzr 2.1.0. Also removelog.show_one_logwhich was never properly deprecated but wasn’t used and is easy to inline if needed. (Vincent Ladeuil)Remove
trace.info,trace.errorandtrace.show_log_errordeprecated in 2.1.0. (Vincent Ladeuil)Remove
TransportListRegistry.set_default_transport, as the concept of a default transport is currently unused. (Jelmer Vernooij)Remove
UIFactory.warn_cross_format_fetchandUIFactory.warn_experimental_format_fetchin favor ofUIFactory.show_user_warning. (Jelmer Vernooij)Tagscontainers can now declare whether they support versioned tags and whether tags can refer to ghost tags. (Jelmer Vernooij)Tags.merge_tonow returns a dictionary with the updated tags and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)There is a new class ContentFilterTree that provides a facade for content filtering. The filtered parameter to export is deprecated in favor of passing a filtered tree, and the specific exporter plugins no longer support it. (Martin Pool)
Transportnow has a_parsed_urlattribute instead of separate_user,_password,_port,_scheme,_hostand_pathattributes. Proxies are provided for the moment but may be removed in the future. (Jelmer Vernooij)
Internals¶
A new debug flag
hpss_client_no_vfswill now cause the HPSS client to raise aHpssVfsRequestNotAllowedexception when a VFS request is attempted. (Jelmer Vernooij)New method
ControlDir._get_selected_branchwhich returns the colocated branch selected using path segment parameters. (Jelmer Vernooij, #380871)
Testing¶
Blackbox tests (including test scripts) can be debugged interactively (see bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)
BranchBuilder.build_snapshot now supports a “flush” action. This cleanly and reliably allows tests using BranchBuilder to construct branches that e.g. rename files out of a directory and unversion that directory in the same revision. Previously some changes were impossible due to the order that build_snapshot performs its actions. (Andrew Bennetts)
Don’t require
os.fdatasyncto be defined on all supported OSes (BSD-based OSes don’t define it). (Vincent Ladeuil, #822649)Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)
LockDircan now be run when the local hostname islocalhost. (Jelmer Vernooij, #825994)ModuleAvailableFeaturewon’t try to import already imported modules, allowing it to be used for modules with side-effects. (Vincent Ladeuil, #712474)Output time stamps while running
make checkto get better timings from pqm. (Vincent Ladeuil, #837926)TestCaseWithMemoryTransport is faster now: _check_safety_net now just compares the bytes in the dirstate file to its pristine state, rather than opening the WorkingTree and calling
last_revision(). This reduces the overall test suite time by about 10% on my laptop. (Andrew Bennetts)Update TestCase.knownFailure to the testtools way of handling expected failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)
