New formats 1.14 and 1.14-rich-root supporting End-Of-Line (EOL) conversions, keyword templating (via the bzr-keywords plugin) and generic content filtering. End-of-line conversion is now supported for formats supporting content filtering.
Changes from 1.14final to 1.14.1
- Change api_minimum_version back to api_minimum_version = (1, 13, 0)
Changes from 1.14rc2 to 1.14final
- Fix a bug in the pure-python GroupCompress code when handling copies longer than 64KiB. (John Arbash Meinel, #364900)
Changes from 1.14rc1 to 1.14rc2
- Fix for bug 358037 Revision not in bzrlib.groupcompress.GroupCompressVersionedFiles (Brian de Alwis, John A Meinel)
- Fix for bug 354036 ErrorFromSmartServer - AbsentContentFactory object has no attribute ‘get_bytes_as’ exception while pulling from Launchpad (Jean-Francois Roy, Andrew Bennetts, Robert Collins)
- Fix for bug 355280 eol content filters are never loaded and thus never applied (Brian de Alwis, Ian Clatworthy)
- bzr.dev -r4280 Change _fetch_uses_deltas = False for CHK repos until we can write a better fix. (John Arbash Meinel, Robert Collins)
- Fix for bug 361574 uncommit recommends undefined –levels and -n options (Marius Kruger, Ian Clatworthy)
- bzr.dev r4289 as cherrypicked at lp:~spiv/bzr/stacking-cherrypick-1.14 (Andrew Bennetts, Robert Collins)
Compatibility Breaks
- A previously disabled code path to accelerate getting configuration settings from a smart server has been reinstated. We think this may cause a incompatibility with servers older than bzr 0.15. We intend to issue a point release to address this if it turns out to be a problem. (Robert Collins, Andrew Bennetts)
- bzr no longer autodetects nested trees as ‘tree-references’. They must now be explicitly added tree references. At the commandline, use join –reference instead of add. (Aaron Bentley)
- The --long log format (the default) no longer shows merged revisions implicitly, making it consistent with the short and line log formats. To see merged revisions for just a given revision, use bzr log -n0 -rX. To see every merged revision, use bzr log -n0. (Ian Clatworthy)
New Features
- New formats 1.14 and 1.14-rich-root supporting End-Of-Line (EOL) conversions, keyword templating (via the bzr-keywords plugin) and generic content filtering. These formats replace the experimental development-wt5 and development-wt5-rich-root formats respectively, but have support for filtered views disabled. (Ian Clatworthy)
- New mv --auto option recognizes renames after they occur. (Aaron Bentley)
- bzr can now get passwords from stdin without requiring a controlling terminal (i.e. by redirecting stdin). (Vincent Ladeuil)
- bzr log now supports filtering of multiple files and directories and will show changes that touch any of them. Furthermore, directory filtering now shows the changes to any children of that directory, not just the directory object itself. (Ian Clatworthy, #97715)
- bzr shelve can now apply changes without storing anything on the shelf, via the new –destroy option. (Aaron Bentley)
- bzr send now accepts –body to specify an initial message body. (Aaron bentley)
- bzr xxx --usage where xxx is a command now shows a usage message and the options without the descriptive help sections (like Description and Examples). A message is also given explaining how to see the complete help, i.e. bzr help xxx. (Ian Clatworthy)
- Content filters can now be used to provide custom conversion between the canonical format of content (i.e. as stored) and the convenience format of content (i.e. as created in working trees). See bzr help content-filters for further details. (Ian Clatworthy, Alexander Belchenko)
- End-of-line conversion is now supported for formats supporting content filtering. See bzr help eol for details. (Ian Clatworthy)
- Newly-blessed join command allows combining two trees into one. (Aaron Bentley)
Improvements
- A new format name alias default-rich-root has been added and points at the closest relative of the default format that supports rich roots. (Jelmer Vernooij, #338061)
- Branching from a stacked branch using bzr*:// will now stream the data when the target repository does not need topological ordering, reducing round trips and network overhead. This uses the existing smart server methods added in 1.13, so will work on any 1.13 or newer server. (Robert Collins, Andrew Bennetts)
- bzr cat and bzr export now supports a --filters option that displays/saves the content after content filters are applied. (Ian Clatworthy)
- bzr ignore gives a more informative message when existing version controlled files match the ignore pattern. (Neil Martinsen-Burrell, #248895)
- bzr log now has --include-merges as an alias for --levels 0. (Ian Clatworthy)
- bzr send is faster on repositories with deep histories. (Ian Clatworthy)
- IPv6 literals are accepted in URLs. (stlman, Martin Pool, Jelmer Vernooij, #165014)
- Progress bars now show the rate of network activity for bzr+ssh:// and bzr:// connections. (Andrew Bennetts)
- Prompt for user names if they are not in the configuration. (Jelmer Vernooij, #256612)
- Pushing to a stacked pack-format branch on a 1.12 or older smart server now takes many less round trips. (Andrew Bennetts, Robert Collins, #294479)
- Streaming push can be done to older repository formats. This is implemented using a new Repository.insert_stream_locked RPC. (Andrew Bennetts, Robert Collins)
- The “ignoring files outside view: ..” message has been re-worded to “Ignoring files outside view. View is ..” to reduce confusion about what was being considered and what was being ignored. (Ian Clatworthy)
- The long log formatter now shows [merge] indicators. If only one level of revisions is displayed and merges are found, the long and short log formatters now tell the user how to see the hidden merged revisions. (Ian Clatworthy)
- The brisbane-core project has delivered its beta format development6-rich-root. This format is suitable for judicious testing by early adopters. In particular if you are benchmarking bzr performance please be sure to test using this format. At this stage more information is best obtained by contacting the Bazaar mailing list or IRC channel if you are interested in using this format. We will make end user documentation available closer to blessing the format as production ready. (Robert Collins, John Arbash Meinel, Ian Clatworthy, Vincent Ladeuil, Andrew Bennetts, Martin Pool)
- Tildes are no longer escaped. No more %7Euser/project/branch! (Jonathan Lange)
Bug Fixes
- Pushing a new stacked branch will also push the parent inventories for revisions at the stacking boundary. This makes sure that the stacked branch has enough data to calculate inventory deltas for all of its revisions (without requiring the fallback branch). This avoids “‘AbsentContentFactory’ object has no attribute ‘get_bytes_as’” errors when fetching the stacked branch from a 1.13 (or later) smart server. This partially fixes #354036. (Andrew Bennetts, Robert Collins)
- End-Of-Line content filters are now loaded correctly. (Ian Clatworthy, Brian de Alwis, #355280)
- Authentication plugins now receive all the parameters from the request itself (aka host, port, realm, path, etc). Previously, only the authentication section name, username and encoded password were provided. (Jean-Francois Roy)
- bzr gives a better message if an invalid regexp is passed to bzr log -m. (Anne Mohsen, Martin Pool)
- bzr split now says “See also: join” (Aaron Bentley, #335015)
- bzr version-info now works in empty branches. (Jelmer Vernooij, #313028)
- Fix “is not a stackable format” error when pushing a stackable-format branch with an unstackable-format repository to a destination with a default stacking policy. (Andrew Bennetts)
- Fixed incorrect “Source format does not support stacking” warning when pushing to a smart server. (Andrew Bennetts, #334114)
- Fix ‘make check-dist-tarball’ failure by converting paths to unicode when needed. (Vincent Ladeuil, #355454)
- Fixed “Specified file ‘x/y/z’ is outside current view: ” occurring on bzr add x/y/z in formats supporting views when no view is defined. (Ian Clatworthy, #344708)
- It is no longer possible to fetch between repositories while the target repository is in a write group. This prevents race conditions that prevent the use of RPC’s to perform fetch, and thus allows optimising more operations. (Robert Collins, Andrew Bennetts)
- merge --force works again. (Robert Collins, #342105)
- No more warnings are issued about sha being deprecated under python-2.6. (Vincent Ladeuil, #346593)
- Pushing a new branch to a server that has a stacking policy will now upgrade from the local branch format when the stacking policy points at a branch which is itself stackable, because we know the client can read both branches, we know that the trunk for the project can be read too, so the upgrade will not inconvenience users. (Robert Collins, #345169)
- Pushing a new stacked branch will also push the parent inventories for revisions at the stacking boundary. This makes sure that the stacked branch has enough data to calculate inventory deltas for all of its revisions (without requiring the fallback branch). This avoids “‘AbsentContentFactory’ object has no attribute ‘get_bytes_as’” errors when fetching the stacked branch from a 1.13 (or later) smart server. This partially fixes #354036. (Andrew Bennetts, Robert Collins)
- The full test suite is passing again on OSX. Several minor issues (mostly test related) have been fixed. (Vincent Ladeuil, #355273).
- The GNU Changelog formatter is slightly improved in the case where the delta is empty, and now correctly claims not to support tags. (Andrea Bolognani)
- Shelve can now shelve changes to a symlink target. (James Westby, #341558)
- The help for the info command has been corrected. (Ian Clatworthy, #351931)
- Upgrade will now use a sensible default format if the source repository uses rich roots. (Jelmer Vernooij, #252908)
Documentation
- Expanded the index of the developer documentation. (Eric Siegerman)
- New topic bzr help debug-flags. (Martin Pool)
- The generated manpage now explicitly lists aliases as commands. (James Westby, #336998)
API Changes
- APIs deprecated in 1.6 and previous versions of bzr are now removed. (Martin Pool)
- CommitReporter is no longer called with unchanged status during commit - this was a full-tree overhead that bzr no longer performs. (Robert Collins)
- New abstract UIFactory method get_username which will be called to obtain the username to use when connecting to remote machines. (Jelmer Vernooij)
- New API Inventory.filter() added that filters an inventory by a set of file-ids so that only those fileids, their parents and their children are included. (Ian Clatworthy)
- New sort order for get_record_stream groupcompress which sorts optimally for use with groupcompress compressors. (John Arbash Meinel, Robert Collins)
- Repository APIs get_deltas_for_revisions() and get_revision_delta() now support an optional specific_fileids parameter. If provided, the deltas are filtered so that only those file-ids, their parents and their children are included. (Ian Clatworthy)
- The get_credentials and set_credentials methods of AuthenticationConfig now accept an optional realm argument. (Jean-Francois Roy)
- The pb argument to fetch() is deprecated. (Martin Pool)
- The Serializer class and the serializer format registry have moved from bzrlib.xml_serializer to bzrlib.serializer. (Jelmer Vernooij)
- The smart server jail now hooks into BzrDir.open to prevent any BzrDir that is not inside the backing transport from being opened. See the module documentation for bzrlib.smart.request for details. (Andrew Bennetts, Robert Collins)
- Tree.get_symlink_target now always returns a unicode string result or None. Previously it would return the bytes from reading the link which could be in any arbitrary encoding. (Robert Collins)
Testing
- bzrlib.tests.TestCase now fails the test if its own setUp and tearDown weren’t called. This catches faulty tests that forget to upcall when overriding setUp and tearDown. Those faulty tests were not properly isolated. (Andrew Bennetts, Robert Collins)
- Fix test_msgeditor.MsgEditorTest test isolation. (Vincent Ladeuil, #347130)
- medusa is not used anymore as an FTP test server starting with python2.6. A new FTP test server based on pyftplib can be used instead. This new server is a soft dependency as medusa which is still preferred if both are available (modulo python version). (Vincent Ladeuil)
Internals
- Added chk_map for fast, trie-based storage of tuple to string maps. (Robert Collins, John Arbash Meinel, Vincent Ladeuil)
- Added bzrlib.chk_map for fast, trie-based storage of tuple to string maps. (Robert Collins, John Arbash Meinel, Vincent Ladeuil)
- Added bzrlib.inventory_delta module. This will be used for serializing and deserializing inventory deltas for more efficient streaming on the network. (Robert Collins, Andrew Bennetts)
- Branch._get_config has been added, which splits out access to the specific config file from the branch. This is used to let RemoteBranch avoid constructing real branch objects to access configuration settings. (Robert Collins, Andrew Bennetts)
- Branch now implements set_stacked_on_url in the base class as the implementation is generic and should impact foreign formats. This helps performance for RemoteBranch push operations to new stacked branches. (Robert Collins, Andrew Bennetts)
- BtreeIndex._spill_mem_keys_to_disk() now generates disk index with optmizations turned off. This only has effect when processing > 100,000 keys during something like bzr pack. (John Arbash Meinel)
- bzr selftest now accepts --subunit to run in subunit output mode. Requires lp:subunit installed to work, but is not a hard dependency. (Robert Collins)
- BzrDir.open_branch now takes an optional ignore_fallbacks parameter for controlling opening of stacked branches. (Andrew Bennetts, Robert Collins)
- CommitBuilder has a new method, record_iter_changes which works in terms of an iter_changes iterator rather than full tree scanning. (Robert Collins)
- DirState can now be passed a custom SHA1Provider object enabling it to store the SHA1 and stat of the canonical (post content filtered) form. (Ian Clatworthy)
- New assertLength method based on one Martin has squirreled away somewhere. (Robert Collins, Martin Pool)
- New hook BzrDir.pre_open which runs before opening BzrDir objects, allowing better enforcement of the smart server jail when dealing with stacked branches. (Robert Collins, Andrew Bennetts)
- New hook RioVersionInfoBuilder.revision, allowing extra entries to be added to the stanza that is printed for a particular revision. (Jelmer Vernooij)
- New repository method refresh_data to cause any repository to make visible data inserted into the repository by a smart server fetch operation. (Robert Collins, Andrew Bennetts)
- register_filter_stack_map now takes an optional fallback parameter, a callable to invoke if a preference has a value not in the map of filter stacks. This enhancement allows, for example, bzr-svn to handle existing svn properties that define a list of keywords to be expanded. (Ian Clatworthy)
- RemoteBranchConfig will use a new verb Branch.set_config_option to write config settings to smart servers that support this, saving 5 round trips on the stacked streaming acceptance test. (Robert Collins, Andrew Bennetts)
- RemoteBranch now provides _get_config for access to just the branch specific configuration from a remote server, which uses the already existing Branch.get_config_file smart verb. (Robert Collins, Andrew Bennetts)
- RemoteRepository will now negatively cache missing revisions during get_parent_map while read-locked. Write-locks are unaffected. (Robert Collins, Andrew Bennetts)
- Removed InterRemoteToOther, InterOtherToRemote and InterPackToRemotePack classes, as they are now unnecessary. (Andrew Bennetts)
- RepositoryFormat as a new attribute fast_deltas to indicate whether the repository can efficiently generate deltas between trees regardless of tree size. (Robert Collins)
- Repository.iter_files_bytes() now properly returns an “iterable of byte strings” (aka ‘chunked’) for the content. It previously was returning a plain string, which worked, but performed very poorly when building a working tree (file.writelines(str) is very inefficient). This can have a large effect on bzr checkout times. (John Arbash Meinel)
- selftest now supports a –parallel option, with values of ‘fork’ or ‘subprocess’ to run the test suite in parallel. Currently only linux machine work, other platforms need patches submitted. (Robert Collins, Vincent Ladeuil)
- tests.run_suite has a new parameter suite_decorators, a list of callables to use to decorate the test suite. Such decorators can add or remove tests, or even remote the test suite to another machine if desired. (Robert Collins)
- The smart server verb Repository.get_parent_map can now include information about ghosts when the special revision include-missing: is in the requested parents map list. With this flag, ghosts are included as missing:REVISION_ID. (Robert Collins, Andrew Bennetts)
- _walk_to_common_revisions will now batch up at least 50 revisions before calling get_parent_map on the target, regardless of InterRepository. (Andrew Bennetts, Robert Collins)
