(Robert Collins, #571437) + +* When passing a file to ``UTF8DirReader`` make sure to close the current + directory file handle after the chdir fails.

None are critical, but upgrading is recommended for all users on +earlier 2.0 releases. + +Bug Fixes +********* + +* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable. + (Martin Pool, #331095) + +* Concurrent autopacking is more resilient to already-renamed pack files. + If we find that a file we are about to obsolete is already obsoleted, we + do not try to rename it, and we leave the file in ``obsolete_packs``. + The code is also fault tolerant if a file goes missing, assuming that + another process already removed the file. + (John Arbash Meinel, Gareth White, #507557) + +* Cope with the lockdir ``held/info`` file being empty, which seems to + happen fairly often if the process is suddenly interrupted while taking + a lock. + (Martin Pool, #185103) + +* Give the warning about potentially slow cross-format fetches much + earlier on in the fetch operation. Don't show this message during + upgrades, and show the correct format indication for remote + repositories. + (Martin Pool, #456077, #515356, #513157) + +* Handle renames correctly when there are files or directories that + differ only in case. (Chris Jones, Martin Pool, #368931) + +* If ``bzr push --create-prefix`` triggers an unexpected ``NoSuchFile`` + error, report that error rather than failing with an unhelpful + ``UnboundLocalError``. + (Andrew Bennetts, #423563) + +* Running ``bzr`` command without any arguments now shows bzr + version number along with rest of the help text. + (Parth Malwankar, #369501) + +* Use osutils.O_NOINHERIT for some files on win32 to avoid PermissionDenied + errors. + (Inada Naoki, #524560) + +Documentation +************* + +* Added ``location-alias`` help topic. + (Andrew Bennetts, #337834) + +* Fixed CHM generation by moving the NEWS section template into + a separate file. (Ian Clatworthy, #524184) + + +bzr 2.0.4 +######### + +:Codename: smooth sailing +:2.0.4: 2010-01-21 + +The fourth bugfix-only release in the 2.0 series contains more than a +dozen bugfixes relative to 2.0.3. The primary focus is on handling +interruptions and concurrent operations more cleanly, there is also a fair +improvement to ``bzr export`` when exporting a remote branch. + + +Bug Fixes +********* + +* ``bzr annotate`` on another branch with ``-r branch:...`` no longer + fails with an ``ObjectNotLocked`` error. (Andrew Bennetts, #496590) + +* ``bzr export dir`` now requests all file content as a record stream, + rather than requsting the file content one file-at-a-time. This can make + exporting over the network significantly faster (54min => 9min in one + case). (John Arbash Meinel, #343218) + +* ``bzr serve`` no longer slowly leaks memory. The compiled + ``bzrlib.bencode.Encoder()`` class was using ``__del__`` to cleanup and + free resources, and it should have been using ``__dealloc__``. + This will likely have an impact on any other process that is serving for + an extended period of time. (John Arbash Meinel, #494406) + +* Check for SIGINT (Ctrl-C) and other signals immediately if ``readdir`` + returns ``EINTR`` by calling ``PyErr_CheckSignals``. This affected the + optional ``_readdir_pyx`` extension. (Andrew Bennetts, #495023) + +* Concurrent autopacks will no longer lose a newly created pack file. + There was a race condition, where if the reload happened at the right + time, the second packer would forget the name of the newly added pack + file. (John Arbash Meinel, Gareth White, #507566) + +* Give a clearer message if the lockdir disappears after being apparently + successfully taken. (Martin Pool, #498378) + +* Give a warning when fetching between repositories (local or remote) with + sufficiently different formats that the content will need to be + serialized (ie ``InterDifferingSerializer`` or ``inventory-deltas``), so + the user has a clue that upgrading could make it faster. + (Martin Pool, #456077) + +* If we fail to open ``~/.bzr.log`` write a clear message to stderr rather + than using ``warning()``. The log file is opened before logging is set + up, and it leads to very confusing: 'no handlers for "bzr"' messages for + users, rather than something nicer. + (John Arbash Meinel, Barry Warsaw, #503886) + +* Refuse to build with any Pyrex 0.9.4 release, as they have known bugs. + (Martin Pool, John Arbash Meinel, #449372) + +* ``setup.py bdist_rpm`` now properly finds extra files needed for the + build. (there is still the distutils bug + http://bugs.python.org/issue644744) (Joe Julian, #175839) + +* The 2a format wasn't properly restarting autopacks when something + changed underneath it (like another autopack). Now concurrent + autopackers will properly succeed. (John Arbash Meinel, #495000) + +* ``TreeTransform`` can now handle when a delta says that the file id for + the tree root changes. Rather than trying to rename your working + directory, or failing early saying that you can't have multiple + tree roots. This also fixes revert, update, and pull when the root id + changes. (John Arbash Meinel, #494269, #504390) + +* ``_update_current_block`` no longer suppresses exceptions, so ^C at just + the right time will get propagated, rather than silently failing to move + the block pointer. (John Arbash Meinel, Gareth White, #495023) + +Testing +******* + +* We have a new ``test_source`` that ensures all pyrex ``cdef`` functions + handle exceptions somehow. (Possibly by setting ``# cannot_raise`` + rather than an ``except ?:`` clause.) This should help prevent bugs like + bug #495023. (John Arbash Meinel) + + +bzr 2.0.3 +######### + +:Codename: little italy +:2.0.3: 2009-12-14 + + +The third stable release of Bazaar has a small handful of bugfixes. As +expected, this has no internal or external compatibility changes versus +2.0.2 (or 2.0.0). + +Bug Fixes +********* + +* ``bzr push --use-existing-dir`` no longer crashes if the directory + exists but contains an invalid ``.bzr`` directory. + (Andrew Bennetts, #423563) + +* Content filters are now applied correctly after pull, merge and switch. + (Ian Clatworthy, #385879) + +* Fix a potential segfault in the groupcompress hash map handling code. + When inserting new entries, if the final hash bucket was empty, we could + end up trying to access if ``(last_entry+1)->ptr == NULL``. + (John Arbash Meinel, #490228) + +* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325) + + +bzr 2.0.2 +######### + +:Codename: after the scare +:2.0.2: 2009-11-02 + +The second in our "let's keep the stable bugfixes flowing" series. As +expected this has a few (~9) bugfixes relative to 2.0.1, and no major api +changes or features. + +Bug Fixes +********* + +* Avoid "NoneType has no attribute st_mode" error when files disappear + from a directory while it's being read. (Martin Pool, #446033) + +* Content filters are now applied correctly after revert. + (Ian Clatworthy) + +* Diff parsing handles "Binary files differ" hunks. (Aaron Bentley, #436325) + +* Fetching from stacked pre-2a repository via a smart server no longer + fails intermittently with "second push failed to complete". + (Andrew Bennetts, #437626) + +* Fix typos left after test_selftest refactoring. + (Vincent Ladeuil, Matt Nordhoff, #461149) + +* Fixed ``ObjectNotLocked`` errors during ``bzr log -r NNN somefile``. + (Andrew Bennetts, #445171) + +* PreviewTree file names are not limited by the encoding of the temp + directory's filesystem. (Aaron Bentley, #436794) + +Improvements +************ + +* ``bzr log`` now read-locks branches exactly once, so makes better use of + data caches. (Andrew Bennetts) + +Documentation +************* + +* Filtered views user documentation upgraded to refer to format 2a + instead of pre-2.0 formats. (Ian Clatworthy) + + +bzr 2.0.1 +######### + +:Codename: Stability First +:2.0.1: 2009-10-14 + +The first of our new ongoing bugfix-only stable releases has arrived. It +includes a collection of 12 bugfixes applied to bzr 2.0.0, but does not +include any of the feature development in the 2.1.0 series. + + +Bug Fixes +********* + +* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the + filename will issue a warning and skip over those files. + (Robert Collins, #3918) + +* bzr will attempt to authenticate with SSH servers that support + ``keyboard-interactive`` auth but not ``password`` auth when using + Paramiko. (Andrew Bennetts, #433846) + +* Fixed fetches from a stacked branch on a smart server that were failing + with some combinations of remote and local formats. This was causing + "unknown object type identifier 60" errors. (Andrew Bennetts, #427736) + +* Fixed ``ObjectNotLocked`` errors when doing some log and diff operations + on branches via a smart server. (Andrew Bennetts, #389413) + +* Handle things like ``bzr add foo`` and ``bzr rm foo`` when the tree is + at the root of a drive. ``osutils._cicp_canonical_relpath`` always + assumed that ``abspath()`` returned a path that did not have a trailing + ``/``, but that is not true when working at the root of the filesystem. + (John Arbash Meinel, Jason Spashett, #322807) + +* Hide deprecation warnings for 'final' releases for python2.6. + (John Arbash Meinel, #440062) + +* Improve the time for ``bzr log DIR`` for 2a format repositories. + We had been using the same code path as for <2a formats, which required + iterating over all objects in all revisions. + (John Arbash Meinel, #374730) + +* Make sure that we unlock the tree if we fail to create a TreeTransform + object when doing a merge, and there is limbo, or pending-deletions + directory. (Gary van der Merwe, #427773) + +* Occasional IndexError on renamed files have been fixed. Operations that + set a full inventory in the working tree will now go via the + apply_inventory_delta code path which is simpler and easier to + understand than dirstates set_state_from_inventory method. This may + have a small performance impact on operations built on _write_inventory, + but such operations are already doing full tree scans, so no radical + performance change should be observed. (Robert Collins, #403322) + +* Retrieving file text or mtime from a _PreviewTree has good performance when + there are many changes. (Aaron Bentley) + +* The CHK index pages now use an unlimited cache size. With a limited + cache and a large project, the random access of chk pages could cause us + to download the entire cix file many times. + (John Arbash Meinel, #402623) + +* When a file kind becomes unversionable after being added, a sensible + error will be shown instead of a traceback. (Robert Collins, #438569) + +Documentation +************* + +* Improved README. (Ian Clatworthy) + +* Improved upgrade documentation for Launchpad branches. + (Barry Warsaw) + + +bzr 2.0.0 +######### + +:2.0.0: 2009-09-22 +:Codename: Instant Karma + +This release of Bazaar makes the 2a (previously 'brisbane-core') format +the default when new branches or repositories are created. This format is +substantially smaller and faster for many operations. Most of the work in +this release focuses on bug fixes and stabilization, covering both 2a and +previous formats. (See the Upgrade Guide for information on migrating +existing projects.) + +This release also improves the documentation content and presentation, +including adding Windows HtmlHelp manuals. + +The Bazaar team decided that 2.0 will be a long-term supported release, +with bugfix-only 2.0.x releases based on it, continuing for at least six +months or until the following stable release. + +Changes from 2.0.0rc2 to final +****************************** + +* Officially branded as 2.0.0 rather than 2.0 to clarify between things + that "want to happen on the 2.0.x stable series" versus things that want + to "land in 2.0.0". (Changes how bzrlib._format_version_tuple() handles + micro = 0.) (John Arbash Meinel) + + +bzr 2.0.0rc2 +############ + +:2.0.0rc2: 2009-09-10 + +New Features +************ + +* Added post_commit hook for mutable trees. This allows the keywords + plugin to expand keywords on files changed by the commit. + (Ian Clatworthy, #408841) + +Bug Fixes +********* + +* Bazaar's native protocol code now correctly handles EINTR, which most + noticeably occurs if you break in to the debugger while connected to a + bzr+ssh server. You can now can continue from the debugger (by typing + 'c') and the process continues. However, note that pressing C-\ in the + shell may still kill the SSH process, which is bug 162509, so you must + sent a signal to the bzr process specifically, for example by typing + ``kill -QUIT PID`` in another shell. (Martin Pool, #341535) + +* ``bzr check`` in pack-0.92, 1.6 and 1.9 format repositories will no + longer report incorrect errors about ``Missing inventory ('TREE_ROOT', ...)`` + (Robert Collins, #416732) + +* ``bzr info -v`` on a 2a format still claimed that it was a "Development + format" (John Arbash Meinel, #424392) + +* ``bzr log stacked-branch`` shows the full log including + revisions that are in the fallback repository. (Regressed in 2.0rc1). + (John Arbash Meinel, #419241) + +* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError`` + traceback. (Martin Pool, #109115) + +* Conversion to 2a will create a single pack for all the new revisions (as + long as it ran without interruption). This improves both ``bzr upgrade`` + and ``bzr pull`` or ``bzr merge`` from local branches in older formats. + The autopack logic that occurs every 100 revisions during local + conversions was not returning that pack's identifier, which resulted in + the partial packs created during the conversion not being consolidated + at the end of the conversion process. (Robert Collins, #423818) + +* Fetches from 2a to 2a are now again requested in 'groupcompress' order. + Groups that are seen as 'underutilized' will be repacked on-the-fly. + This means that when the source is fully packed, there is minimal + overhead during the fetch, but if the source is poorly packed the result + is a fairly well packed repository (not as good as 'bzr pack' but + good-enough.) (Robert Collins, John Arbash Meinel, #402652) + +* Fix a potential segmentation fault when doing 'log' of a branch that had + ghosts in its mainline. (Evaluating None as a tuple is bad.) + (John Arbash Meinel, #419241) + +* ``groupcompress`` sort order is now more stable, rather than relying on + ``topo_sort`` ordering. The implementation is now + ``KnownGraph.gc_sort``. (John Arbash Meinel) + +* Local data conversion will generate correct deltas. This is a critical + bugfix vs 2.0rc1, and all 2.0rc1 users should upgrade to 2.0rc2 before + converting repositories. (Robert Collins, #422849) + +* Network streams now decode adjacent records of the same type into a + single stream, reducing layering churn. (Robert Collins) + +* Prevent some kinds of incomplete data from being committed to a 2a + repository, such as revisions without inventories, a missing chk_bytes + record for an inventory, or a missing text referenced by an inventory. + (Andrew Bennetts, #423506, #406687) + +Documentation +************* + +* Fix assertion error about "_remember_remote_is_before" when pushing to + older smart servers. + (Andrew Bennetts, #418931) + +* Help on hooks no longer says 'Not deprecated' for hooks that are + currently supported. (Ian Clatworthy, #422415) + +* PDF and CHM (Windows HtmlHelp) formats are now supported for the + user documentation. The HTML documentation is better broken up into + topics. (Ian Clatworthy) + +* The developer and foreign language documents are now separated + out so that searching in the HTML and CHM files produces more + useful results. (Ian Clatworthy) + +* The main table of contents now provides links to the new Migration Docs + and Plugins Guide. (Ian Clatworthy) + + +bzr 2.0.0rc1 +############ + +:Codename: no worries +:2.0.0rc1: 2009-08-26 + +Compatibility Breaks +******************** + +* The default format for bzr is now ``2a``. This format brings many + significant performance and size improvements. bzr can pull from + any existing repository into a ``2a`` one, but can only transfer + from ``2a`` into ``rich-root`` repositories. The Upgrade guide + has more information about this change. (Robert Collins) + +* On Windows auto-detection of Putty's plink.exe is disabled. + Default SSH client for Windows is paramiko. User still can force + usage of plink if explicitly set environment variable BZR_SSH=plink. + (#414743, Alexander Belchenko) + +New Features +************ + +* ``bzr branch --switch`` can now switch the checkout in the current directory + to the newly created branch. (Lukáš Lalinský) + +Bug Fixes +********* + +* Further tweaks to handling of ``bzr add`` messages about ignored files. + (Jason Spashett, #76616) + +* Fetches were being requested in 'groupcompress' order, but weren't + recombining the groups. Thus they would 'fragment' to get the correct + order, but not 'recombine' to actually benefit from it. Until we get + recombining to work, switching to 'unordered' fetches avoids the + fragmentation. (John Arbash Meinel, #402645) + +* Fix a pycurl related test failure on karmic by recognizing an error + raised by newer versions of pycurl. + (Vincent Ladeuil, #306264) + +* Fix a test failure on karmic by making a locale test more robust. + (Vincent Ladeuil, #413514) + +* Fix IndexError printing CannotBindAddress errors. + (Martin Pool, #286871) + +* Fix "Revision ... not present" errors when upgrading stacked branches, + or when doing fetches from a stacked source to a stacked target. + (Andrew Bennetts, #399140) + +* ``bzr branch`` of 2a repositories over HTTP is much faster. bzr now + batches together small fetches from 2a repositories, rather than + fetching only a few hundred bytes at a time. + (Andrew Bennetts, #402657) + +Improvements +************ + +* A better description of the platform is shown in crash tracebacks, ``bzr + --version`` and ``bzr selftest``. + (Martin Pool, #409137) + +* bzr can now (again) capture crash data through the apport library, + so that a single human-readable file can be attached to bug reports. + This can be disabled by using ``-Dno_apport`` on the command line, or by + putting ``no_apport`` into the ``debug_flags`` section of + ``bazaar.conf``. + (Martin Pool, Robert Collins, #389328) + +* ``bzr push`` locally on windows will no longer give a locking error with + dirstate based formats. (Robert Collins) + +* ``bzr shelve`` and ``bzr unshelve`` now work on windows. + (Robert Collins, #305006) + +* Commit of specific files no longer prevents using the iter_changes + codepath. On 2a repositories, commit of specific files should now be as + fast, or slightly faster, than a full commit. (Robert Collins) + +* The internal core code that handles specific file operations like + ``bzr st FILENAME`` or ``bzr commit FILENAME`` has been changed to + include the parent directories if they have altered, and when a + directory stops being a directory its children are always included. This + fixes a number of causes for ``InconsistentDelta`` errors, and permits + faster commit of specific paths. (Robert Collins, #347649) + +Documentation +************* + +* New developer documentation for content filtering. + (Martin Pool) + +API Changes +*********** + +* ``bzrlib.shelf_ui`` has had the ``from_args`` convenience methods of its + classes changed to manage lock lifetime of the trees they open in a way + consistent with reader-exclusive locks.
