A number of bugs have +been fixed, particularly in interoperability between different formats or +different releases of Bazaar over there network. There's been substantial +internal work in both the repository and network code to enable new features +and faster performance. + +Bug Fixes +********* + +* Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would break + if the remote server was < version 1.2. This was due to a bug in the + RemoteRepository.get_parent_map() fallback code. + (John Arbash Meinel, Andrew Bennetts, #214894) + + +bzr 1.4rc2 +########## + +:Released: 2008-04-21 + +Bug Fixes +********* + +* ``bzr log -r ..X bzr://`` was failing, because it was getting a request + for ``revision_id=None`` which was not a string. + (John Arbash Meinel, #211661) + +* Fixed a bug in handling ghost revisions when logging changes in a + particular file. (John Arbash Meinel, #209948) + +* Fix error about "attempt to add line-delta in non-delta knit". + (Andrew Bennetts, #205156) + +* Fixed performance degradation in fetching from knit repositories to + knits and packs due to parsing the entire revisions.kndx on every graph + walk iteration fixed by using the Repository.get_graph API. There was + another regression in knit => knit fetching which re-read the index for + every revision each side had in common. + (Robert Collins, John Arbash Meinel) + + +bzr 1.4rc1 +########## + +:Released: 2008-04-11 + +Changes +******* + +* bzr main script cannot be imported (Benjamin Peterson) + +* On GNU/Linux bzr additionally looks for plugins in arch-independent site + directory. (Toshio Kuratomi) + +* The ``set_rh`` branch hook is now deprecated. Please migrate + any plugins using this hook to use an alternative, e.g. + ``post_change_branch_tip``. (Ian Clatworthy) + +* When a plugin cannot be loaded as the file path is not a valid + python module name bzr will now strip a ``bzr_`` prefix from the + front of the suggested name, as many plugins (e.g. bzr-svn) + want to be installed without this prefix. It is a common mistake + to have a folder named "bzr-svn" for that plugin, especially + as this is what bzr branch lp:bzr-svn will give you. (James Westby, + Andrew Cowie) + +* UniqueIntegerBugTracker now appends bug-ids instead of joining + them to the base URL. Plugins that register bug trackers may + need a trailing / added to the base URL if one is not already there. + (James Wesby, Andrew Cowie) + +Features +******** + +* Added start_commit hook for mutable trees. (Jelmer Vernooij, #186422) + +* ``status`` now accepts ``--no-pending`` to show the status without + listing pending merges, which speeds up the command a lot on large + histories. (James Westby, #202830) + +* New ``post_change_branch_tip`` hook that is called after the + branch tip is moved but while the branch is still write-locked. + See the User Reference for signature details. + (Ian Clatworthy, James Henstridge) + +* Reconfigure can convert a branch to be standalone or to use a shared + repository. (Aaron Bentley) + +Improvements +************ + +* The smart protocol now has support for setting branches' revision info + directly. This should make operations like push slightly faster, and is a + step towards server-side hooks. The new request method name is + ``Branch.set_last_revision_info``. (Andrew Bennetts) + +* ``bzr commit --fixes`` now recognises "gnome" as a tag by default. + (James Westby, Andrew Cowie) + +* ``bzr switch`` will attempt to find branches to switch to relative to the + current branch. E.g. ``bzr switch branchname`` will look for + ``current_branch/../branchname``. (Robert Collins, Jelmer Vernooij, + Wouter van Heyst) + +* Diff is now more specific about execute-bit changes it describes + (Chad Miller) + +* Fetching data over HTTP is a bit faster when urllib is used. This is done + by forcing it to recv 64k at a time when reading lines in HTTP headers, + rather than just 1 byte at a time. (Andrew Bennetts) + +* Log --short and --line are much faster when -r is not specified. + (Aaron Bentley) + +* Merge is faster. We no longer check a file's existence unnecessarily + when merging the execute bit. (Aaron Bentley) + +* ``bzr status`` on an explicit list of files no longer shows pending + merges, making it much faster on large trees. (John Arbash Meinel) + +* The launchpad directory service now warns the user if they have not set + their launchpad login and are trying to resolve a URL using it, just + in case they want to do a write operation with it. (James Westby) + +* The smart protocol client is slightly faster, because it now only queries + the server for the protocol version once per connection. Also, the HTTP + transport will now automatically probe for and use a smart server if + one is present. You can use the new ``nosmart+`` transport decorator + to get the old behaviour. (Andrew Bennetts) + +* The ``version`` command takes a ``--short`` option to print just the + version number, for easier use in scripts. (Martin Pool) + +* Various operations with revision specs and commands that calculate + revnos and revision ids are faster. (John A. Meinel, Aaron Bentley) + +Bugfixes +******** + +* Add ``root_client_path`` parameter to SmartWSGIApp and + SmartServerRequest. This makes it possible to publish filesystem + locations that don't exactly match URL paths. SmartServerRequest + subclasses should use the new ``translate_client_path`` and + ``transport_from_client_path`` methods when dealing with paths received + from a client to take this into account. (Andrew Bennetts, #124089) + +* ``bzr mv a b`` can be now used also to rename previously renamed + directories, not only files. (Lukáš Lalinský, #107967) + +* ``bzr uncommit --local`` can now remove revisions from the local + branch to be symmetric with ``bzr commit --local``. + (John Arbash Meinel, #93412) + +* Don't ask for a password if there is no real terminal. + (Alexander Belchenko, #69851) + +* Fix a bug causing a ValueError crash in ``parse_line_delta_iter`` when + fetching revisions from a knit to pack repository or vice versa using + bzr:// (including over HTTP or SSH). + (#208418, Andrew Bennetts, Martin Pool, Robert Collins) + +* Fixed ``_get_line`` in ``bzrlib.smart.medium``, which was buggy. Also + fixed ``_get_bytes`` in the same module to use the push back buffer. + These bugs had no known impact in normal use, but were problematic for + developers working on the code, and were likely to cause real bugs sooner + or later. (Andrew Bennetts) + +* Implement handling of basename parameter for DefaultMail. (James Westby) + +* Incompatibility with Paramiko versions newer than 1.7.2 was fixed. + (Andrew Bennetts, #213425) + +* Launchpad locations (lp: URLs) can be pulled. (Aaron Bentley, #181945) + +* Merges that add files to deleted root directories complete. They + do create conflicts. (Aaron Bentley, #210092) + +* vsftp's return ``550 RNFR command failed.`` supported. + (Marcus Trautwig, #129786) + +Documentation +************* + +* Improved documentation on send/merge relationship. (Peter Schuller) + +* Minor fixes to the User Guide. (Matthew Fuller) + +* Reduced the evangelism in the User Guide. (Ian Clatworthy) + +* Added Integrating with Bazaar document for developers (Martin Albisetti) + +API Breaks +********** + +* Attempting to pull data from a ghost aware repository (e.g. knits) into a + non-ghost aware repository such as weaves will now fail if there are + ghosts. (Robert Collins) + +* ``KnitVersionedFile`` no longer accepts an ``access_mode`` parameter, and + now requires the ``index`` and ``access_method`` parameters to be + supplied. A compatible shim has been kept in the new function + ``knit.make_file_knit``. (Robert Collins) + +* Log formatters must now provide log_revision instead of show and + show_merge_revno methods. The latter had been deprecated since the 0.17 + release. (James Westby) + +* ``LoopbackSFTP`` is now called ``SocketAsChannelAdapter``. + (Andrew Bennetts) + +* ``osutils.backup_file`` is removed. (Alexander Belchenko) + +* ``Repository.get_revision_graph`` is deprecated, with no replacement + method. The method was size(history) and not desirable. (Robert Collins) + +* ``revision.revision_graph`` is deprecated, with no replacement function. + The function was size(history) and not desirable. (Robert Collins) + +* ``Transport.get_shared_medium`` is deprecated. Use + ``Transport.get_smart_medium`` instead. (Andrew Bennetts) + +* ``VersionedFile`` factories now accept a get_scope parameter rather + than using a call to ``transaction_finished``, allowing the removal of + the fixed list of versioned files per repository. (Robert Collins) + +* ``VersionedFile.annotate_iter`` is deprecated. While in principle this + allowed lower memory use, all users of annotations wanted full file + annotations, and there is no storage format suitable for incremental + line-by-line annotation. (Robert Collins) + +* ``VersionedFile.clone_text`` is deprecated. This performance optimisation + is no longer used - reading the content of a file that is undergoing a + file level merge to identical state on two branches is rare enough, and + not expensive enough to special case. (Robert Collins) + +* ``VersionedFile.clear_cache`` and ``enable_cache`` are deprecated. + These methods added significant complexity to the ``VersionedFile`` + implementation, but were only used for optimising fetches from knits - + which can be done from outside the knit layer, or via a caching + decorator. As knits are not the default format, the complexity is no + longer worth paying. (Robert Collins) + +* ``VersionedFile.create_empty`` is removed. This method presupposed a + sensible mapping to a transport for individual files, but pack backed + versioned files have no such mapping. (Robert Collins) + +* ``VersionedFile.get_graph`` is deprecated, with no replacement method. + The method was size(history) and not desirable. (Robert Collins) + +* ``VersionedFile.get_graph_with_ghosts`` is deprecated, with no + replacement method. The method was size(history) and not desirable. + (Robert Collins) + +* ``VersionedFile.get_parents`` is deprecated, please use + ``VersionedFile.get_parent_map``. (Robert Collins) + +* ``VersionedFile.get_sha1`` is deprecated, please use + ``VersionedFile.get_sha1s``. (Robert Collins) + +* ``VersionedFile.has_ghost`` is now deprecated, as it is both expensive + and unused outside of a single test. (Robert Collins) + +* ``VersionedFile.iter_parents`` is now deprecated in favour of + ``get_parent_map`` which can be used to instantiate a Graph on a + VersionedFile. (Robert Collins) + +* ``VersionedFileStore`` no longer uses the transaction parameter given + to most methods; amongst other things this means that the + get_weave_or_empty method no longer guarantees errors on a missing weave + in a readonly transaction, and no longer caches versioned file instances + which reduces memory pressure (but requires more careful management by + callers to preserve performance). (Robert Collins) + +Testing +******* + +* New -Dselftest_debug flag disables clearing of the debug flags during + tests. This is useful if you want to use e.g. -Dhpss to help debug a + failing test. Be aware that using this feature is likely to cause + spurious test failures if used with the full suite. (Andrew Bennetts) + +* selftest --load-list now uses a new more agressive test loader that will + avoid loading unneeded modules and building their tests. Plugins can use + this new loader by defining a load_tests function instead of a test_suite + function. (a forthcoming patch will provide many examples on how to + implement this). + (Vincent Ladeuil) + +* selftest --load-list now does some sanity checks regarding duplicate test + IDs and tests present in the list but not found in the actual test suite. + (Vincent Ladeuil) + +* Slightly more concise format for the selftest progress bar, so there's + more space to show the test name. (Martin Pool) :: + + [2500/10884, 1fail, 3miss in 1m29s] test_revisionnamespaces.TestRev + +* The test suite takes much less memory to run, and is a bit faster. This + is done by clearing most attributes of TestCases after running them, if + they succeeded. (Andrew Bennetts) + +Internals +********* + +* Added ``_build_client_protocol`` to ``_SmartClient``. (Andrew Bennetts) + +* Added basic infrastructure for automatic plugin suggestion. + (Martin Albisetti) + +* If a ``LockableFiles`` object is not explicitly unlocked (for example + because of a missing ``try/finally`` block, it will give a warning but + not automatically unlock itself. (Previously they did.) This + sometimes caused knock-on errors if for example the network connection + had already failed, and should not be relied upon by code. + (Martin Pool, #109520) + +* ``make dist`` target to build a release tarball, and also + ``check-dist-tarball`` and ``dist-upload-escudero``. (Martin Pool) + +* The ``read_response_tuple`` method of ``SmartClientRequestProtocol*`` + classes will now raise ``UnknownSmartMethod`` when appropriate, so that + callers don't need to try distinguish unknown request errors from other + errors. (Andrew Bennetts) + +* ``set_make_working_trees`` is now implemented provided on all repository + implementations (Aaron Bentley) + +* ``VersionedFile`` now has a new method ``get_parent_map`` which, like + ``Graph.get_parent_map`` returns a dict of key:parents.
