Added the Mini Tutorial + and Quick Start Summary (en) documents from the Wiki, improving the + content and readability of the former. Formatted NEWS as Release Notes + complete with a Table of Conents, one heading per release. Moved the + Developer Guide into the main document catalog and provided a link + from the developer document catalog back to the main one. + (Ian Clatworthy, Sabin Iacob, Alexander Belchenko) + + +API Changes +*********** + +* The static convenience method ``BzrDir.create_repository`` + is deprecated. Callers should instead create a ``BzrDir`` instance + and call ``create_repository`` on that. (Martin Pool) + + +bzr 0.90rc1 +########### + +:Released: 2007-08-14 + +Bugfixes +******** + +* ``bzr init`` should connect to the remote location one time only. We + have been connecting several times because we forget to pass around the + Transport object. This modifies ``BzrDir.create_branch_convenience``, + so that we can give it the Transport we already have. + (John Arbash Meinel, Vincent Ladeuil, #111702) + +* Get rid of SFTP connection cache (get rid of the FTP one too). + (Vincent Ladeuil, #43731) + +* bzr branch {local|remote} remote don't try to create a working tree + anymore. + (Vincent Ladeuil, #112173) + +* All identified multiple connections for a single bzr command have been + fixed. See bzrlib/tests/commands directory. + (Vincent Ladeuil) + +* ``bzr rm`` now does not insist on ``--force`` to delete files that + have been renamed but not otherwise modified. (Marius Kruger, + #111664) + +* ``bzr selftest --bench`` no longer emits deprecation warnings + (Lukáš Lalinský) + +* ``bzr status`` now honours FILE parameters for conflict lists + (Aaron Bentley, #127606) + +* ``bzr checkout`` now honours -r when reconstituting a working tree. + It also honours -r 0. (Aaron Bentley, #127708) + +* ``bzr add *`` no more fails on Windows if working tree contains + non-ascii file names. (Kuno Meyer, #127361) + +* allow ``easy_install bzr`` runs without fatal errors. + (Alexander Belchenko, #125521) + +* Graph._filter_candidate_lca does not raise KeyError if a candidate + is eliminated just before it would normally be examined. (Aaron Bentley) + +* SMTP connection failures produce a nice message, not a traceback. + (Aaron Bentley) + +Improvements +************ + +* Don't show "dots" progress indicators when run non-interactively, such + as from cron. (Martin Pool) + +* ``info`` now formats locations more nicely and lists "submit" and + "public" branches (Aaron Bentley) + +* New ``pack`` command that will trigger database compression within + the repository (Robert Collins) + +* Implement ``_KnitIndex._load_data`` in a pyrex extension. The pyrex + version is approximately 2-3x faster at parsing a ``.kndx`` file. + Which yields a measurable improvement for commands which have to + read from the repository, such as a 1s => 0.75s improvement in + ``bzr diff`` when there are changes to be shown. (John Arbash Meinel) + +* Merge is now faster. Depending on the scenario, it can be more than 2x + faster. (Aaron Bentley) + +* Give a clearer warning, and allow ``python setup.py install`` to + succeed even if pyrex is not available. + (John Arbash Meinel) + +* ``DirState._read_dirblocks`` now has an optional Pyrex + implementation. This improves the speed of any command that has to + read the entire DirState. (``diff``, ``status``, etc, improve by + about 10%). + ``bisect_dirblocks`` has also been improved, which helps all + ``_get_entry`` type calls (whenever we are searching for a + particular entry in the in-memory DirState). + (John Arbash Meinel) + +* ``bzr pull`` and ``bzr push`` no longer do a complete walk of the + branch revision history for ui display unless -v is supplied. + (Robert Collins) + +* ``bzr log -rA..B`` output shifted to the left margin if the log only + contains merge revisions. (Kent Gibson) + +* The ``plugins`` command is now public with improved help. + (Ian Clatworthy) + +* New bundle and merge directive formats are faster to generate, and + +* Annotate merge now works when there are local changes. (Aaron Bentley) + +* Commit now only shows the progress in terms of directories instead of + entries. (Ian Clatworthy) + +* Fix ``KnitRepository.get_revision_graph`` to not request the graph 2 + times. This makes ``get_revision_graph`` 2x faster. (John Arbash + Meinel) + +* Fix ``VersionedFile.get_graph()`` to avoid using + ``set.difference_update(other)``, which has bad scaling when + ``other`` is large. This improves ``VF.get_graph([version_id])`` for + a 12.5k graph from 2.9s down to 200ms. (John Arbash Meinel) + +* The ``--lsprof-file`` option now generates output for KCacheGrind if + the file starts with ``callgrind.out``. This matches the default file + filtering done by KCacheGrind's Open Dialog. (Ian Clatworthy) + +* Fix ``bzr update`` to avoid an unnecessary + ``branch.get_master_branch`` call, which avoids 1 extra connection + to the remote server. (Partial fix for #128076, John Arbash Meinel) + +* Log errors from the smart server in the trace file, to make debugging + test failures (and live failures!) easier. (Andrew Bennetts) + +* The HTML version of the man page has been superceded by a more + comprehensive manual called the Bazaar User Reference. This manual + is completed generated from the online help topics. As part of this + change, limited reStructuredText is now explicitly supported in help + topics and command help with 'unnatural' markup being removed prior + to display by the online help or inclusion in the man page. + (Ian Clatworthy) + +* HTML documentation now use files extension ``*.html`` + (Alexander Belchenko) + +* The cache of ignore definitions is now cleared in WorkingTree.unlock() + so that changes to .bzrignore aren't missed. (#129694, Daniel Watkins) + +* ``bzr selftest --strict`` fails if there are any missing features or + expected test failures. (Daniel Watkins, #111914) + +* Link to registration survey added to README. (Ian Clatworthy) + +* Windows standalone installer show link to registration survey + when installation finished. (Alexander Belchenko) + +Library API Breaks +****************** + +* Deprecated dictionary ``bzrlib.option.SHORT_OPTIONS`` removed. + Options are now required to provide a help string and it must + comply with the style guide by being one or more sentences with an + initial capital and final period. (Martin Pool) + +* KnitIndex.get_parents now returns tuples. (Robert Collins) + +* Ancient unused ``Repository.text_store`` attribute has been removed. + (Robert Collins) + +* The ``bzrlib.pack`` interface has changed to use tuples of bytestrings + rather than just bytestrings, making it easier to represent multiple + element names. As this interface was not used by any internal facilities + since it was introduced in 0.18 no API compatibility is being preserved. + The serialised form of these packs is identical with 0.18 when a single + element tuple is in use. (Robert Collins) + +Internals +********* + +* merge now uses ``iter_changes`` to calculate changes, which makes room for + future performance increases. It is also more consistent with other + operations that perform comparisons, and reduces reliance on + Tree.inventory. (Aaron Bentley) + +* Refactoring of transport classes connected to a remote server. + ConnectedTransport is a new class that serves as a basis for all + transports needing to connect to a remote server. transport.split_url + have been deprecated, use the static method on the object instead. URL + tests have been refactored too. + (Vincent Ladeuil) + +* Better connection sharing for ConnectedTransport objects. + transport.get_transport() now accepts a 'possible_transports' parameter. + If a newly requested transport can share a connection with one of the + list, it will. + (Vincent Ladeuil) + +* Most functions now accept ``bzrlib.revision.NULL_REVISION`` to indicate + the null revision, and consider using ``None`` for this purpose + deprecated. (Aaron Bentley) + +* New ``index`` module with abstract index functionality. This will be + used during the planned changes in the repository layer. Currently the + index layer provides a graph aware immutable index, a builder for the + same index type to allow creating them, and finally a composer for + such indices to allow the use of many indices in a single query. The + index performance is not optimised, however the API is stable to allow + development on top of the index. (Robert Collins) + +* ``bzrlib.dirstate.cmp_by_dirs`` can be used to compare two paths by + their directory sections. This is equivalent to comparing + ``path.split('/')``, only without having to split the paths. + This has a Pyrex implementation available. + (John Arbash Meinel) + +* New transport decorator 'unlistable+' which disables the list_dir + functionality for testing. + +* Deprecated ``change_entry`` in transform.py. (Ian Clatworthy) + +* RevisionTree.get_weave is now deprecated. Tree.plan_merge is now used + for performing annotate-merge. (Aaron Bentley) + +* New EmailMessage class to create email messages. (Adeodato Simó) + +* Unused functions on the private interface KnitIndex have been removed. + (Robert Collins) + +* New ``knit.KnitGraphIndex`` which provides a ``KnitIndex`` layered on top + of a ``index.GraphIndex``. (Robert Collins) + +* New ``knit.KnitVersionedFile.iter_parents`` method that allows querying + the parents of many knit nodes at once, reducing round trips to the + underlying index. (Robert Collins) + +* Graph now has an is_ancestor method, various bits use it. + (Aaron Bentley) + +* The ``-Dhpss`` flag now includes timing information. As well as + logging when a new connection is opened. (John Arbash Meinel) + +* ``bzrlib.pack.ContainerWriter`` now returns an offset, length tuple to + callers when inserting data, allowing generation of readv style access + during pack creation, without needing a separate pass across the output + pack to gather such details. (Robert Collins) + +* ``bzrlib.pack.make_readv_reader`` allows readv based access to pack + files that are stored on a transport. (Robert Collins) + +* New ``Repository.has_same_location`` method that reports if two + repository objects refer to the same repository (although with some risk + of false negatives). (Andrew Bennetts) + +* InterTree.compare now passes require_versioned on correctly. + (Marius Kruger) + +* New methods on Repository - ``start_write_group``, + ``commit_write_group``, ``abort_write_group`` and ``is_in_write_group`` - + which provide a clean hook point for transactional Repositories - ones + where all the data for a fetch or commit needs to be made atomically + available in one step. This allows the write lock to remain while making + a series of data insertions. (e.g. data conversion). (Robert Collins) + +* In ``bzrlib.knit`` the internal interface has been altered to use + 3-tuples (index, pos, length) rather than two-tuples (pos, length) to + describe where data in a knit is, allowing knits to be split into + many files. (Robert Collins) + +* ``bzrlib.knit._KnitData`` split into cache management and physical access + with two access classes - ``_PackAccess`` and ``_KnitAccess`` defined. + The former provides access into a .pack file, and the latter provides the + current production repository form of .knit files. (Robert Collins) + +Testing +******* + +* Remove selftest ``--clean-output``, ``--numbered-dirs`` and + ``--keep-output`` options, which are obsolete now that tests + are done within directories in $TMPDIR. (Martin Pool) + +* The SSH_AUTH_SOCK environment variable is now reset to avoid + interaction with any running SSH agents. (Jelmer Vernooij, #125955) + +* run_bzr_subprocess handles parameters the same way as run_bzr: + either a string or a list of strings should be passed as the first + parameter. Varargs-style parameters are deprecated. (Aaron Bentley) + + +.. + vim: tw=74 ft=rst ff=unix + |
