End-of-line conversion is now supported for formats supporting content filtering.
The Bazaar team is happy to announce availability of a new release of the bzr adaptive version control system. Thanks to everyone who contributed patches, suggestions, and feedback. Bazaar is now available for download from http://bazaar-vcs.org/Download as a source tarball; packages for various systems will be available soon. 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'. Theymust 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 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) 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 send`` is faster on repositories with deep histories. (Ian Clatworthy) * Progress bars now show the rate of network activity for ``bzr+ssh://`` and ``bzr://`` connections. (Andrew Bennetts)* 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 stagemore 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 asproduction 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 ********* * 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) * 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 nowupgrade 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)
* 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 verisons 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 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 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 usedinstead. 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) * ``Branch._get_config`` has been added, which splits out access to thespecific 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 withoptmizations 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 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 wasreturning 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 linuxmachine 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 includeinformation about ghosts when the special revision ``include- missing:``
is in the requested parents map list. With this flag, ghosts areincluded 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) -- Bob Tanner <[email protected]> Key fingerprint = F785 DDFC CF94 7CE8 AA87 3A9D 3895 26F1 0DDB E378
