Bazaar Release Notes¶
bzr 2.4.3¶
- 2.4.3:
NOT RELEASED YET
External Compatibility Breaks¶
New Features¶
Improvements¶
Bug Fixes¶
Cope with Unix filesystems, such as smbfs, where chmod gives ‘permission denied’. (Martin Pool, #606537)
During merges, when two entries end up using the same path for two different file-ids (the same file being ‘bzr added’ in two different branches) , ‘duplicate’ conflicts are created instead of ‘content’ ones. This was previously leading to a ‘Malformed tramsform’ exception. (Vincent Ladeuil, #880701)
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)
Handle when an uncommit/update tries to add a file to an otherwise empty directory. The
Dirstate.update_basis_by_delta
would end up incorrectly flagging the delta as invalid. (Brian de Alwis, #855155)‘Malformed transform’ exceptions are now recognized as internal errors instead of user errors and report a traceback. This will reduce user confusion as there is generally nothing users can do about them. (Vincent Ladeuil, #880701)
Prevent a traceback being printed to stderr when logging has problems and accept utf-8 byte string without breaking. (Martin Packman, #714449)
Some filesystems give
EOPNOTSUPP
when trying to callfdatasync
. This shouldn’t be treated as a fatal error. (John Arbash Meinel, #1075108)Teach the bzr client how to reconnect if we get
ConnectionReset
while 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. This is a backport of the functionality in bzr-2.5. (John Arbash Meinel, #819604)Use
encoding_type='exact'
forbzr testament
so that on Windows the sha hash of the long testament matches the sha hash in the short form. (John Arbash Meinel, #1010339)When the
limbo
orpending-deletion
directories exist, typically because of an interrupted tree update, but are empty, bzr no longer errors out, because there is nothing for the user to clean up. Also, errors in creation of these directories are no longer squelched. (Martin Pool, #427773)_Win32Stat object provides members st_uid and st_gid, those are present in Python’s os.stat object. These members required for external tools like bzr-git and dulwich. (Alexander Belchenko, #967060)
Documentation¶
API Changes¶
Internals¶
Testing¶
Account for slightly improved compression with newer versions of zlib in
bt.test_btree_index
tests. (Martin Packman, #940453)
bzr 2.4.2¶
- 2.4.2:
2011-10-27
This is a bugfix release. Most of the bugs dealt with portability issues. Upgrading is recommended for all users of earlier 2.4 releases.
External Compatibility Breaks¶
None.
New Features¶
None.
Improvements¶
Fixed a bug where
bzr tags -r x..y
loaded the branch history once for every revision in the range; it’s now much faster. (Vincent Ladeuil, #857335)
Bug Fixes¶
Fixed an infinite loop when creating a repo at the root of the filesystem, i.e. “/”, due to posixpath.normpath() not collapsing 2 leading slashes into one, thus respecting the POSIX standard, but making relpath() loop infinitely. (Florian Vichot, #861008)
Fixed loading of external merge tools from config to properly decode command-lines which contain embedded quotes. (Gordon Tyler, #828803)
Include declaration of ‘changed’ to avoid an UnboundLocalError in dirstate pyrex code with new Cython versions. (Denys Duchier, #837221)
Prevent several kinds of OverflowError and other fallout from failing to fit stat fields into four bytes in dirstate pack_stat implementations. (Martin Packman, #683191 #706957)
Return early from create_delta_index_from_delta given tiny inputs. This avoids raising a spurious MemoryError on certain platforms such as AIX. (John Arbash Meinel, #856731)
Documentation¶
Corrected documentation for
bzr serve
in the Admin Guide. (Morten Bøgeskov, Martin Pool, #832576)
API Changes¶
None.
Internals¶
No changes.
Testing¶
Accept both old and new style testtools output in selftest tests. (Jelmer Vernooij, Martin Packman, #815423)
Fix the race for TestingThreadingTCPServer in test_server_crash_while_responding. (Vincent Ladeuil, #869366)
Really corrupt the pack file without depending on a special length or value. (Vincent Ladeuil, #807032)
bzr 2.4.1¶
- 2.4.1:
2011-09-08
This is a bugfix release. Upgrading is recommended for all users of earlier 2.4 releases.
It includes fixes from previous stable releases and address some issues with the test suite.
External Compatibility Breaks¶
New Features¶
Improvements¶
Bug Fixes¶
config.LocationMatcher
properly excludes unrelated sections. (Vincent Ladeuil, #829237)dirstate.fdatasync
andrepository.fdatasync
can now properly be disabled. (Vincent Ladeuil, #824513)Disable
os.fsync
andos.fdatasync
by default when runningbzr selftest
. You can use--sync
to re-enable them. (John Arbash Meinel, #837293)Fix i18n use when no environment variables are set. (Jelmer Vernooij, #810701)
Avoid UnicodeDecode error when reporting EINVAL from transports. (IWATA Hidetaka, #829237)
Documentation¶
Corrected documentation for BZR_PROGRESS_BAR. (Dennis Benzinger, #735417)
API Changes¶
Internals¶
Testing¶
The test suite should now be able to run under weird environments where
/etc/passwd
doesn’t contain theuid
for the user running selftest or wherefakeroot
is used but/root
is inacessible. (Vincent Ladeuil, #825027)
bzr 2.4.0¶
- 2.4.0:
2011-08-11
This release marks the start of a new long-term-stable series. From here, we will only make bugfix releases on the 2.4 series (2.4.1, etc, and support it until February 2013), while 2.5 will become our new development series.
This is a bugfix and polish release over the 2.3 series, with a large number of bugs fixed (>150 for the 2.4 series alone), and some performance improvements. Support for python 2.4 and 2.5 has been dropped, many large working tree operations have been optimized as well as some stacked branches operations.
Only bugfixes from other stables series have been included since 2.4b5 so all known fixed bugs are included here.
Users are encouraged to upgrade from the other stable series.
External Compatibility Breaks¶
New Features¶
Improvements¶
Bug Fixes¶
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)
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)
Cope with not all Python versions having a
clear
method onTestCase._type_equality_funcs
. (Martin [gz], Jelmer Vernooij, #809048)Fetching tags when fetching the tip revision of a branch is now controlled by the config setting
branch.fetch_tags
. The behavior has been reverted to 2.3’s not-fetching tagged revisions by default. (John Arbash Meinel, #771184)The fix for bug #513709 caused us to open a new connection when switching a lightweight checkout that was pointing at a bound branch. This isn’t necessary because we know the master URL without opening it, avoiding an extra SSH connection, etc. (John Arbash Meinel, #812285)
Documentation¶
API Changes¶
Internals¶
Testing¶
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)
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)
bzr 2.4b5¶
- 2.4b5:
2011-07-07
This is the fifth (and last) beta of the 2.4 series leading to 2.4.0 release in August 2011. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins.
This release includes all bug fixed in previous series known at the time of this release.
External Compatibility Breaks¶
None.
New Features¶
New command
verify-signatures
to check if all commits or specified commits have digital signatures from trusted keys. Requires python-gpgme to be installed.New option
--signatures
forbzr log
to display digital signature verification results for each commit.Config option acceptable_keys to list which GPG keys are verified as trusted.
Config option validate_signatures_in_log to always show signatures in
bzr log
.
Improvements¶
Branch.open
is now about 3x faster (about 2ms instead of 6.5ms). (Andrew Bennetts).Pack, dirstate, and index files are synced to persistent storage if possible when writing finishes, to reduce the risk of problems caused by a machine crash or similar problem. This can be turned off through the
dirstate.fdatasync
andrepository.fdatasync
options, which can be set inlocations.conf
orbazaar.conf
. (Martin Pool, #343427)
Bug Fixes¶
Display a proper error message when a config file content cannot be decoded as UTF-8 or when it cannot be parsed. (Vincent Ladeuil, #502060, #688677, #797246)
Generate a single conflict (instead of two) when merging a branch modifying and renaming a file in a branch that deleted it (or vice-versa). (Vincent Ladeuil, #688101)
Give a more helpful message when the bzr executable doesn’t match the library. (This typically happens because of a misconfigured PYTHONPATH or half-installed bzr.) (Martin Pool, #804553)
Properly load utf8-encoded config files. (Vincent Ladeuil, #799212)
GraphThunkIdsToKeys.merge_sort
now properly returns keys rather than ids. (Jelmer Vernooij, #799677)TreeTransformBase.fixup_new_roots
can now check that a tree root is present. (Jelmer Vernooij, #801257)
API Changes¶
New attributes
WorkingTreeFormat.supports_versioned_directories
andRepositoryFormat.supports_versioned_directories
. (Jelmer Vernooij, #765815)The “revno” field type when using the python version-info format is now a string (to handle dotted revnos) (Benoît Pierre, #796259)
Internals¶
Start implementing localization, starting with command help text (but not the command options themselves). This will allow bootstrapping the bzr internationalization process. (Inada Naoki)
Testing¶
Fix test failures when running as a homeless user (debian buildd). Tests leaking into
${HOME}/.bzr.log
should be detected properly now. (Vincent Ladeuil, #798698)
bzr 2.4b4¶
- 2.4b4:
2011-06-16
This is the fourth beta of the 2.4 series, leading to a 2.4.0 release in August 2011. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins.
This release includes all bug fixed in previous series known at the time of this release.
External Compatibility Breaks¶
Do not treat configuration option ‘check_signatures = require’ as if it were ‘create_signatures = always’ (Jonathan Riddell)
New Features¶
Hooks have been added for config stacks:
get
,set
andremove
are called when an option is respectively read, modified or deleted. Also addedload
andsave
hooks for config stores, called when the stores are loaded or saved. (Vincent Ladeuil)New hook server_exception in bzrlib.smart.server to catch any exception caused while running bzr serve. (Jonathan Riddell, #274578)
New hook set_commit_message in bzrlib.msgeditor to set a commit message and revision properties. (Jonathan Riddell, #274578)
Support
-S
as an alias for--short
for thelog
andmissing
commands. (Martin von Gagern, #38655)
Improvements¶
bzr annotate
can be run without setting whoami data first. (Jonathan Riddell, #667408)
Bug Fixes¶
Bazaar can now detect when a lock file is held by a dead process originating from the same machine, and steal the lock after printing a message to the user. This is off by default, for safety, but can be turned on by setting the configuration variable
locks.steal_dead
toTrue
. (Martin Pool, #220464)bzr version-info
now works when the tree is on a dotted revno. (Benoît Pierre, #796259)Credentials in the log output produced by
-Dhttp
are masked so users can more freely post them in bug reports. (Vincent Ladeuil, #723074)Fix a race condition for
server_started
hooks leading to a spurious test failure. (Vincent Ladeuil, #789167)Fix exporting subdirectory with
--per-file-timestamps
. (Szilveszter Farkas, #795557)Handle files that get created but don’t get used during TreeTransform.
open()
can create a file, and still raise an exception before it returns. So anything we might have created, make sure we destroy duringfinalize()
. (Martin [gz], #597686)pack_repo
now usesTransport.move
instead ofTransport.rename
, deleting any existing targets even on SFTP. (Martin von Gagern, #421776)Pass the
build_mo
command to the rest of the setup() calls in setup.py. Thebdist_wininst
andpy2exe
code paths were failing becausebuild_mo
became a required step that they didn’t know about. (John Arbash Meinel, #787122)Preserve existing
root-id
when merging an unrelated branch. (Aaron Bentley, #806356)Properly avoid re-adding a file after it changes case on CICP filesystems. (John Arbash Meinel, #798130)
Reports the original error when an InvalidHttpResponse exception is encountered to facilitate debug. (Vincent Ladeuil, #788530)
Reports a non-existent file error when trying to merge in a file that does not exist. (Jonathan Riddell, #330063)
UIFactory.prompt
,UIFactory.get_username
,UIFactory.get_password
andUIFactory.get_boolean
now require a unicode prompt to be passed in. (Jelmer Vernooij, #592083)Support merging into the empty tree. (Aaron Bentley, #595328)
Documentation¶
Improve documentation of
bzr merge --force
. (Neil Martinsen-Burrell, #767307)Make docs for configuration options for digital signatures match reality. (Jonathan Riddell)
Add user-guide page on GPG signatures. (Jonathan Riddell)
API Changes¶
Checking for a file id in a Tree or Inventory using
in
is now deprecated. Instead, use has_id. (Martin Pool)Exporters are now all exposed as generators, rather than as single-call functions, so that calling code can take stream the output. (Xaav, Martin Pool)
Information about held lockdir locks returned from eg LockDir.peek is now represented as a LockHeldInfo object, rather than a plain Python dict. (Martin Pool)
Remove file_status function. (Martin Pool)
Repository.iter_reverse_revision_history
is now deprecated. UseGraph.iter_lefthand_ancestry
instead. (Jelmer Vernooij, #739481)Repository.get_ancestry
has been deprecated. UseGraph.iter_ancestry
instead. (Jelmer Vernooij, #784511)
Internals¶
tools/check-newsbugs.py
accepts a--browser
option to open corresponding launchpad pages in a browser. (Vincent Ladeuil)
Testing¶
A ImportTariffTestCase base class has been added in
bzrlib.tests.test_import_tariff
, which can be used for import tariff tests in plugins. (Jelmer Vernooij, #793465)Fix deadlock in TestImportTariffs.test_simple_serve when stderr gets more output than fits in the default buffer. This was happening on the Windows buildslave, and could easily happen in other circumstances where the default OS buffer size for pipes is small or the
python -v
output is large. (Andrew Bennetts, #784802)Fix spurious test failure on OSX for WorkingTreeFormat2. (Vincent Ladeuil, #787942)
Re-target
bb.test_merge.TestMerge.test_merge_reversed_revision_range
and rewrite it as a parametrized test to avoid unrelated failures. (Vincent Ladeuil, #795456)Show log file contents from subprocesses started by start_bzr_subprocess in test failure details. This may help diagnose strange hangs and failures involving subprocesses. (Andrew Bennetts)
Skip
utextwrap
tests whensphinx
breaks text_wrap by an hostile monkey-patch to textwrap.TextWrapper.wordsep_re. (Vincent Ladeuil, #785098)Multiple
selftest --exclude
options are now combined instead of overriding each other. (Vincent Ladeuil, #746991)Restore some
FTPTransport
test coverage by allowingpyftpdlib 0.6.0
to be used. Also restoremedusa
support while leaving it disabled to make it easier to use if/when we can in the future. (Vincent Ladeuil, #781140)TestImportTariffs no longer uses the real
$HOME
. This prevents it from polluting$HOME/.bzr.log
or being accidentally influenced by user configuration such as aliases. It still runs with all the user’s plugins enabled, as intended. (Vincent Ladeuil, Andrew Bennetts, #789505)
bzr 2.4b3¶
- 2.4b3:
2011-05-26
This is the third beta of the 2.4 series, leading to a 2.4.0 release in August 2011. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins.
This release includes all bug fixed in previous series known at the time of this release.
External Compatibility Breaks¶
bzr-2.4
has officially dropped support for python2.4 and python2.5. We will continue to maintainbzr-2.3
for people who still need to use those versions of python. (John Arbash Meinel)
New Features¶
The text compressor used for 2a repositories now has a tweakable parameter that can be set in bazaar.conf.
bzr.groupcompress.max_entries_per_source
default of 65536. When doing compression, we build up an index of locations to match against. Setting this higher will result in slightly better compression, at a cost of more memory. Note that a value of 65k represents fully sampling a 1MB file. So this only has an effect when compressing texts larger than N*16 bytes. (John Arbash Meinel, #602614)
Improvements¶
bzr branch --stacked
from a smart server uses the network a little more efficiently. For a simple branch it reduces the number of round-trips by about 20%. (Andrew Bennetts)bzr log --line
scales the width of the author field with the size of the line. This means that the full author name is shown when the environment variable BZR_COLUMNS=0. (Neil Martinsen-Burrell)bzr pull
now properly triggers the fastCHKInventory.iter_changes
rather than the slow generic inter-Inventory changes. It used to use aDirStateRevisionTree
as one of the source trees, which is faster when we have to read the whole inventory anyway, but much slower when we can get just the delta out of the repository. On a 70k record tree, this changesbzr pull
from 28s down to 17s. (John Arbash Meinel, #780677)Slightly reduced memory consumption when fetching into a 2a repository by reusing existing caching a little better. (Andrew Bennetts)
Speed up
bzr status
by a little bit when there are a couple of modified files. We now track how many files we have seen that need updating, and only rewrite the dirstate file if enough of them have changed. The default is 10, and can be overridden by setting the branch option “bzr.workingtree.worth_saving_limit
”. (Ian Clatworthy, John Arbash Meinel, #380202)Speed up
bzr uncommit
. Instead of resetting the dirstate from scratch, useupdate_basis_by_delta
, computing the delta from the repository. (John Arbash Meinel, #780544)
Bug Fixes¶
All Tree types can now be exported as tar.*, zip or directories. (Aaron Bentley)
bzr merge --no-remember location
never setssubmit_branch
. (Vincent Ladeuil, #782169)bzr pull --no-remember location
never setsparent_location
.bzr push --no-remember location
never setspush_location
.bzr send --no-remember submit_location public_location
never setssubmit_branch
norpublic_branch
. (Vincent Ladeuil)Conflicts involving non-ascii filenames are now properly reported rather than failing with a UnicodeEncodeError. (Martin [GZ], #686161)
Correct parent is now set when using ‘switch -b’ with bound branches. (A. S. Budden, #513709)
Fix bzr plugins regression in bzr 2.4 which resulted in a traceback from writelines on ckj terminals. (Martin [GZ], #754082)
WT.inventory
andWT.iter_entries_by_dir()
was not correctly reporting subdirectories that were tree references (in formats that supported them). (John Arbash Meinel, #764677)Merging into empty branches now gives an error as this is currently not supported. (Jonathan Riddell, #242175)
Do not show exception to user on pointless commit error. (Jonathan Riddell #317357)
WT.update_basis_by_delta
no longer requires that the deltas match the current WT state. This allowsupdate_basis_by_delta
to be used by more commands than just commit. Updating with a delta allows us to not load the whole inventory, which can take 10+s with large trees. (Jonathan Riddell, John Arbash Meinel, #781168)bzr mv --after old_name new_name
now works if “new_name” is newly added. (Benoît Pierre)
Documentation¶
Restore the workaround for option names including dots (–1.14) which was disabled when we stopped listing –1.9 as a format. (Vincent Ladeuil, #782289)
API Changes¶
annotate_file
has been deprecated in favor ofannotate_file_revision_tree
. (Jelmer Vernooij, #775598)Branch.fetch
now takes an optionallimit
argument. (Andrew Bennetts, Jelmer Vernooij, #750175)Inter.get
now raisesNoCompatibleInter
if there are no compatible optimisers rather than an instance of the class it is called on. (Jelmer Vernooij)Branch.push
now takes alossy
argument.Branch.lossy_push
has been removed. (Jelmer Vernooij)New method
Repository.get_file_graph
which can return the per-file revision graph. (Jelmer Vernooij, #775578)The default implementation of
Branch
is now oriented to storing the branch tip. Branch implementations which store the full history should now subclassFullHistoryBzrBranch
.Branch._last_revision_info
has been renamed toBranch._read_last_revision_info
(Jelmer Vernooij)Tree.__iter__
has been deprecated; useTree.all_file_ids
instead. (Jelmer Vernooij)Tree.get_symlink_target
now takes an optionalpath
argument. (Jelmer Vernooij)
Internals¶
MutableTree.smart_add
now uses inventory deltas. (Jelmer Vernooij, #146165)Removed
bzrlib.branch._run_with_write_locked_target
asbzrlib.cleanup
provides the same functionality in a more general way. (Andrew Bennetts)
Testing¶
A test that was expected to fail but passes instead now counts as a failure catching up with new testtools and subunit handling. (Martin [GZ], #654474)
Make it easier for plugins to reuse the per_workingtree scenarios by restoring the wt_scenarios helper that was accidentally deleted. (Vincent Ladeuil, #783472)
Removed
test_breakin
tests that were excessively prone to hanging, did not work on Wine, and partly already disabled. (Martin Pool, #408814, #746985)Windows locations are different and should be tested accordingly. (Vincent Ladeuil, #788131)
bzr 2.4b2¶
- 2.4b2:
2011-04-28
This is the second beta of the 2.4 series, leading to a 2.4.0 release in August 2011. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins.
This release includes all bug fixed in previous series known at the time of this release.
External Compatibility Breaks¶
Two command synonyms for
bzr branch
have been deprecated, to avoid confusion and to allow the names to later be reused. The removed names are:get
andclone
. (Martin Pool, #506265)
New Features¶
bzr commit
now supports a--lossy
argument that can be used to discard any data that can not be natively represented when committing to a foreign VCS. (Jelmer Vernooij, #587721)
Improvements¶
bzr merge
in large trees is now significantly faster. On a 70k entry tree, the time went from ~3min down to 30s. This also effectsbzr pull
andbzr update
since they use the same merge logic to update the WorkingTree. (John Arbash Meinel, #759091)bzr revert
now properly usesbzr status
’s optimizediter_changes
. This can be a significant performance difference (33s to 5s on large trees). (John Arbash Meinel, #759096)Resolve
lp:FOO
urls locally rather than doing an XMLRPC request if the user has donebzr launchpad-login
. The bzr+ssh URLs were already being handed off to the remote server anyway (xmlrpc has been mappinglp:bzr
tobzr+ssh://bazaar.launchpad.net/+branch/bzr
, rather thanbzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev
for a few months now.) By doing it ourselves, we can cut out substantial startup time. From Netherlands to London it was taking 368ms to do the XMLRPC call as much as 2s from Sydney. You can test the local logic by using-Dlaunchpad
. (John Arbash Meinel, #397739)When building a new WorkingTree (such as during
bzr co
orbzr branch
) we now properly store the stat and hash of files that are old enough. This saves a fair amount of time on the firstbzr status
(on a 500MB tree, it saves about 30+s). (John Arbash Meinel, #740932)
Bug Fixes¶
Arguments that can’t be decoded to unicode in the current posix locale give a clearer error message without a traceback. (Martin [gz], #745712)
bzrlib.log._DEFAULT_REQUEST_PARAMS
is no longer accidentally mutated bybzrlib.log._apply_log_request_defaults
. In practice these default values aren’t relied on very often so this probably wasn’t causing any trouble. (Andrew Bennetts)bzr log
now works on revisions which are not in the current branch. (Matt Giuca, #241998)Don’t rewrite the dirstate file when non-interesting changes have occurred. This can significantly improve ‘bzr status’ times when there are only small changes to a large tree. (Ian Clatworthy, John Arbash Meinel, #380202)
Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)
bzrlib.merge.Merge
now callsiter_changes
withoutinclude_unversioned=True
. This makes it significantly faster in many cases, because it only looks at modified files, rather than building information about all files. This can cause failures in other TreeTransform code, because it had been expecting to know the names of things which had not changed (such as parent directories). All cases we know about so far have been fixed, but there may be fallout for edge cases that we are missing. (John Arbash Meinel, #759091)SFTPTransport
is more pro-active about closing file-handles. This reduces the chance of having threads fail from async requests while running the test suite. (John Arbash Meinel, #656170)Standalone bzr.exe installation on Windows: user can put additional python libraries into
site-packages
subdirectory of the installation directory, this might be required for “installing” extra dependencies for some plugins. (Alexander Belchenko, #743256)transform.revert()
has been updated to usewt.iter_changes(basis_tree)
rather thanbasis_tree.iter_changes(wt)
. This allows the optimized code path to kick in, improvingbzr revert
times significantly (33s to 4s on large trees, 0.7s to 0.3s on small trees.) (John Arbash Meinel, #759096)TreeTransform.create_file/new_file
can now take an optionalsha1
parameter. If supplied, when the transform is applied, it will then callself._tree._observed_sha1
for those files. This lets us update the hash-cache for content that we create, preventing us from re-reading the content in the nextbzr status
. (John Arbash Meinel, #740932)
Documentation¶
Added a section about using a shared SSH account on a server for bzr+ssh access. (Russell Smith)
The documentation now recommends using SSH rather than SFTP in the tutorials and the examples, because that will generally be much faster and better in cases where it can be used. SFTP is still available and mentioned as an alternative. (Martin Pool, #636712)
API Changes¶
Branch.update_revisions
has been made private and should no longer be used by external users. UseBranch.pull
orBranch.push
instead. (Jelmer Vernooij, #771765)Commands now have an invoked_as attribute, showing the name under which they were called before alias expansion. (Martin Pool)
Hooks.create_hook
is now deprecated in favour ofHooks.add_hook
. (Jelmer Vernooij)If you call bzrlib.initialize but forget to enter the resulting object as a context manager, bzrlib will now be initialized anyhow. (Previously simple programs calling bzrlib might find the library was mysteriously silent.) (Martin Pool)
Inventory-specific functionality has been split out of
Tree
into a newInventoryTree
class. Tree instances no longer necessarily provide aninventory
attribute. (Jelmer Vernooij)Inventory-specific functionality has been split out of
RevisionTree
into a newInventoryRevisionTree
class. RevisionTree instances no longer necessarily provide aninventory
attribute. (Jelmer Vernooij)New method
Hooks.uninstall_named_hook
. (Jelmer Vernooij, #301472)revision_graph_can_have_wrong_parents
is now an attribute onRepositoryFormat
rather than a method onRepository
. (Jelmer Vernooij)Testament
now takes atree
rather than aninventory
. (Jelmer Vernooij, #762608)TestCase.failUnlessExists
andfailIfExists
are deprecated in favour ofassertPathExists
andassertPathDoesNotExist
respectively. (Martin Pool)The
revno
parameter oflog.LogRevision
may now be None, representing a revision which is not in the current branch. (Matt Giuca, #241998)The various knit pack repository format classes have been moved from
bzrlib.repofmt.pack_repo
tobzrlib.repofmt.knitpack_repo
. (Jelmer Vernooij)RevisionTree
now has a new methodget_file_revision
. (Jelmer Vernooij)WorkingTree
no longer provides aninventory
. Instead, all inventory-related functionality is now on the subclassInventoryWorkingTree
that all native Bazaar working tree implementations derive from. (Jelmer Vernooij)
Internals¶
Added
osutils.lstat
andosutils.fstat
. These are just theos
functions on Linux, but they are wrapped on Windows so that fstat matches lstat results across all python versions. (John Arbash Meinel)WorkingTree._observed_sha1
also updates the ‘size’ column. It happened to be updated as a side-effect of commit, but if we start using the function elsewhere we might as well do it directly. (John Arbash Meinel)
Testing¶
Stop using failIf, failUnless, failIfEqual, etc, that give PendingDeprecationWarnings on Python2.7. (Martin Pool, #760435)
bzr 2.4b1¶
- 2.4b1:
2011-03-17
This is the first beta of the 2.4 series, leading up to a 2.4.0 release in August 2011. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins. Some plugins may need small updates to work with 2.4b1.
External Compatibility Breaks¶
(none)
New Features¶
Added
changelog_merge
plugin for merging changes toChangelog
files in GNU format. Seebzr help changelog_merge
for details. (Andrew Bennetts)Configuration options can now use references to other options in the same file by enclosing them with curly brackets (
{other_opt}
). This makes it possible to use, for example,push_location=lp:~vila/bzr/config-{nickname}
inbranch.conf
when using a loom. During the beta period, the default behaviour is to disable this feature. It can be activated by declaringbzr.config.expand = True
inbazaar.conf
. (Vincent Ladeuil)External merge tools can now be configured in bazaar.conf. See
bzr help configuration
for more information. (Gordon Tyler, #489915)The
lp:
directory service now supports Launchpad’s QA staging. (Jelmer Vernooij, #667483)
Improvements¶
A new hidden command
bzr repair-workingtree
. This is a way to force the dirstate file to be rebuilt, rather than using abzr checkout
workaround. (John Arbash Meinel)Added a
Branch.heads_to_fetch
RPC to the smart server protocol. This allows formats from plugins (such as looms) to efficiently tell the client which revisions need to be fetched. (Andrew Bennetts)Branching, merging and pulling a branch now copies revisions named in tags, not just the tag metadata. (Andrew Bennetts, #309682)
bzr cat-revision
no longer requires a working tree. (Jelmer Vernooij, #704405)bzr export --per-file-timestamps
for .tar.gz files will now override the mtime for trees exported on Python 2.7 and later, which expose the ‘mtime’ field in gzip files. This makes the output ofbzr export --per-file-timestamps
for a particular tree deterministic. (Jelmer Vernooij, #711226)bzr export --format=zip
can now export to standard output, like the other exporters can. (Jelmer Vernooij, #513752)bzr export
can now create.tar.xz
and.tar.lzma
files. (Jelmer Vernooij, #551714)Getting all entries from
CHKInventory.iter_entries_by_dir()
has been sped up dramatically for large trees. Iterating by dir is not the best way to load data from a CHK inventory, so it preloads all the items in the correct order. (With the gcc-tree, this changes it (re)reading 8GB of CHK data, down to just 150MB.) This has noticeable affects for things like building checkouts, etc. (John Arbash Meinel, #737234)
Bug Fixes¶
A MemoryError thrown on the server during a remote operation will now be usefully reported, and other unexpected errors will include the class name. (Martin [gz], #722416)
bzr annotate -r-1 file
will now properly annotate a deleted file. (Andrew King, #537442)bzr export
to zip files will now set a mode on directories. (Jelmer Vernooij, #207253)bzr export
to tgz files will only write out the basename of the tarfile to the gzip file. (Jelmer Vernooij, #102234)bzr push --overwrite
with an older revision specified will now correctly roll back the target branch. (Jelmer Vernooij, #386576)bzr lp-propose
can now propose merges against packaging branches on Launchpad without requiring the target branch to be specified. (Jelmer Vernooij, #704647)bzr lp-propose
no longer requires a reviewer to be specified. It will instead leave setting the reviewer up to Launchpad if it was not specified. (Jelmer Vernooij, #583772)bzr pull
will now exit with exit code 1 if there were tag conflicts. (Jelmer Vernooij, #213185)bzr mv
user errors no longer throw UnicodeEncodeError with non-ascii paths, however they may still print junk if not on a UTF-8 terminal. (Martin [gz], #707954)bzr reconfigure --unstacked
now copies revisions (and their ancestors) named in tags into the unstacked repository, not just the ancestry of the branch’s tip. (Andrew Bennetts, #401646)bzr serve
no longer crashes when a server_started hook is installed and IPv6 support is available on the system. (Jelmer Vernooij, #293697)bzr status
will not rewrite the dirstate file if it only has ‘trivial’ changes. (Currently limited to dir updates and newly-added files changing state.) This saves a bit of time for regular operations. eg.bzr status
in a 100k tree takes 1.4s to compute the status, but 1s to re-save the dirstate file. (John Arbash Meinel, #765881)bzr tags
will no longer choke on branches with ghost revisions in their mainline and tags on revisions not in the branch ancestry. (Jelmer Vernooij, #397556)bzr whoami
will now display an error if both a new identity and--email
were specified. (Jelmer Vernooij, #680449)launchpadlib
doesn’t provide theuris
module in some old versions. (Vincent Ladeuil, #706835)Empty entries in the
NO_PROXY
variable are no longer treated as matching every host. (Martin Pool, #586341)Plugins incompatible with the current version of bzr no longer produce a warning on every command invocation. Instead, a message is shown by
bzr plugins
and in crash reports. (#704195, Martin Pool)The “pretty” version of
needs_read_lock
andneeds_write_lock
now preserves the identity of default parameter values. (Andrew Bennetts, #718569)bzr dump-btree --raw
no longer tracebacks on a B-Tree file containing no rows. (Eric Siegerman, #715508)Fix
bzr lp-mirror
to work on command line branch URLs and branches without an explicit public location. (Max Bowsher)On Python 2.6 and higher, use multiprocessing.cpu_count() to retrieve the number of available processors. (Jelmer Vernooij, #693140)
API Changes¶
Added
Branch.heads_to_fetch
method. Implementations of the Branch API must now inherit or implement this method. (Andrew Bennetts, #721328)Added
bzrlib.mergetools
module with helper functions for working with the list of external merge tools. (Gordon Tyler, #489915)All methods and arguments that were deprecated before 2.0 have been removed. (Jelmer Vernooij)
Branch formats should now be registered on the format registry (
bzrlib.branch.format_registry
) rather than using the class methods onBranchFormat
. (Jelmer Vernooij, #714729)Branch.set_revision_history
is now deprecated. (Jelmer Vernooij)BranchFormat.supports_leaving_lock()
andRepositoryFormat.supports_leaving_lock
flags have been added. (Jelmer Vernooij)Branch.fetch
implementations must now accept an optionalfetch_tags
keyword argument. (Andrew Bennetts)Branch.import_last_revision_info
is deprecated. Use theimport_last_revision_info_and_tags
method instead. (Andrew Bennetts)Because it was too specific to BzrDir implementations,
ControlDir.sprout
no longer has a default implementation; it now raisesNotImplementedError
. (Jelmer Vernooij, #717937)bzrlib.deprecated_graph
has been removed.bzrlib.graph
scales better tree and should be used instead. (Jelmer Vernooij, #733612)ControlDirFormat.register_format
has been removed. Instead,Prober
implementations should now implement aknown_formats
method. (Jelmer Vernooij)ControlDirFormats can now provide a
check_status
method and raise a custom exception or warning when an unsupported or deprecated format is being opened. (Jelmer Vernooij, #731311)bzrlib.revionspec.dwim_revspecs
is deprecated. Usebzrlib.revisionspec.RevisionSpec_dwim.append_possible_revspec
andbzrlib.revisionspec.RevisionSpec_dwim.append_possible_lazy_revspec
instead. (Jelmer Vernooij, #721971)BzrDirFormat
has a new attributefixed_components
that indicates whether the components of the bzrdir can be upgraded independent of theBzrDir
. (Jelmer Vernooij)BzrProber.register_format
andBzrProber.unregister_format
are now deprecated in favour of theBzrProber.formats
format registry. (Jelmer Vernooij)ControlDir
implementations no longer have to provide theget_branch_transport
,get_workingtree_transport
andget_repository_transport
methods. (Jelmer Vernooij, #730325)Converter
has been moved frombzrlib.bzrdir
tobzrlib.controldir
. (Jelmer Vernooij)Repository formats can now provide
_get_extra_interrepo_test_combinations
in the same module to provide extra test combinations forbzrlib.tests.per_repository
. (Jelmer Vernooij)Repository formats should now be registered on the format registry (
bzrlib.repository.format_registry
) rather than using the class methods onRepositoryFormat
. (Jelmer Vernooij)Repository formats can now indicate they do not support the full VersionedFiles API by setting the
supports_full_versioned_files
attribute to False. A subset of the VersionedFiles API (signatures and text graphs) still needs to be supported. (Jelmer Vernooij)Repository formats have a new method
is_deprecated
that implementations can override to return True to trigger a deprecation warning. (Jelmer Vernooij)The
revision_id
parameter ofRepository.search_missing_revision_ids
andInterRepository.search_missing_revision_ids
is deprecated. It is replaced by therevision_ids
parameter. (Andrew Bennetts)Working tree formats should now be registered on the format registry (
bzrlib.working_tree.format_registry
) rather than using the class methods onWorkingTreeFormat
. (Jelmer Vernooij, #714730)Exporting may now be done with a generator (
bzrlib.export.get_export_generator
) (Geoff/xaav, #791005)
Internals¶
CatchingExceptionThread
(formerly ThreadWithException) has been moved out of thebzrlib.tests
hierarchy to make it clearer that it can be used outside of tests. This class makes it easier to track exceptions in threads by catching them so they can be re-raised in the controlling thread. It’s available in thebzrlib.cethread
module. (Vincent Ladeuil)Correctly propagate malloc failures from diff-delta.c code as MemoryError so OOM conditions during groupcompress are clearly reported. This entailed a change to several function signatures. (Martin [gz], #633336)
HookPoint.lazy_hook
andHooks.install_named_lazy_hook
can install hooks for which the callable is loaded lazily. (Jelmer Vernooij)
Testing¶
The Range parsing for HTTP requests will correctly parse incomplete ranges. (Vincent Ladeuil, #731240)
