#################### Bazaar Release Notes #################### .. toctree:: :maxdepth: 1 bzr 1.7.1 ######### :Released: 2008-10-01 No changes from 1.7.1rc1. bzr 1.7.1rc1 ############ :Released: 2008-09-24 This release just includes an update to how the merge algorithm handles file paths when we encounter complex history. Features ******** * If we encounter a criss-cross in history, use information from direct Least Common Ancestors to resolve inventory shape (locations of files, adds, deletes, etc). This is similar in concept to using ``--lca`` for merging file texts, only applied to paths. (John Arbash Meinel) bzr 1.7 ####### :Released: 2008-09-23 This release includes many bug fixes and a few performance and feature improvements. ``bzr rm`` will now scan for missing files and remove them, like how ``bzr add`` scans for unknown files and adds them. A bit more polish has been applied to the stacking code. The b-tree indexing code has been brought in, with an eye on using it in a future repository format. There are only minor installer changes since bzr-1.7rc2. Features ******** * Some small updates to the win32 installer. Include localization files found in plugins, and include the builtin distutils as part of packaging qbzr. (Mark Hammond) bzr 1.7rc2 ########## :Released: 2008-09-17 A few bug fixes from 1.7rc1. The biggest change is a new ``RemoteBranch.get_stacked_on_url`` RPC. This allows clients that are trying to access a Stacked branch over the smart protocol, to properly connect to the stacked-on location. Bug Fixes ********* * Branching from a shared repository on a smart server into a new repository now preserves the repository format. (Andrew Bennetts, #269214) * Branching from a stacked branch via ``bzr+ssh`` can properly connect to the stacked-on branch. (Martin Pool, #261315) * ``bzr init`` no longer re-opens the BzrDir multiple times. (Vincent Ladeuil) * Fix '_in_buffer' AttributeError when using the -Dhpss debug flag. (Andrew Bennetts) bzr 1.7rc1 ########## :Released: 2008-09-09 This release candidate for bzr 1.7 has several bug fixes and a few performance and feature improvements. ``bzr rm`` will now scan for missing files and remove them, like how ``bzr add`` scans for unknown files and adds them. A bit more polish has been applied to the stacking code. The b-tree indexing code has been brought in, with an eye on using it in a future repository format. Changes ******* * ``bzr export`` can now export a subdirectory of a project. (Robert Collins) * ``bzr remove-tree`` will now refuse to remove a tree with uncommitted changes, unless the ``--force`` option is specified. (Lukáš Lalinský, #74101) * ``bzr rm`` will now scan for files that are missing and remove just them automatically, much as ``bzr add`` scans for new files that are not ignored and adds them automatically. (Robert Collins) Features ******** * Support for GSSAPI authentication when using FTP as documented in RFC2228. (Jelmer Vernooij, #49623) * Add support for IPv6 in the smart server. (Jelmer Vernooij, #165014) Improvements ************ * A URL like ``log+file:///tmp`` will log all access to that Transport to ``.bzr.log``, which may help in debugging or profiling. (Martin Pool) * ``bzr branch`` and ``bzr push`` use the default stacking policy if the branch format supports it. (Aaron Bentley) * ``bzr init`` and ``bzr init-repo`` will now print out the same as ``bzr info`` if it completed successfully. (Marius Kruger) * ``bzr uncommit`` logs the old tip revision id, and displays how to restore the branch to that tip using ``bzr pull``. This allows you to recover if you realize you uncommitted the wrong thing. (John Arbash Meinel) * Fix problems in accessing stacked repositories over ``bzr://``. (Martin Pool, #261315) * ``SFTPTransport.readv()`` was accidentally using ``list += string``, which 'works', but adds each character separately to the list, rather than using ``list.append(string)``. Fixing this makes the SFTP transport a little bit faster (~20%) and use a bit less memory. (John Arbash Meinel) * When reading index files, if we happen to read the whole file in a single request treat it as a ``_buffer_all`` request. This happens most often on small indexes over remote transports, where we default to reading 64kB. It saves a round trip for each small index during fetch operations. Also, if we have read more than 50% of an index file, trigger a ``_buffer_all`` on the next request. This works around some inefficiencies because reads don't fall neatly on page boundaries, so we would ignore those bytes, but request them again later. This could trigger a total read size of more than the whole file. (John Arbash Meinel) Bug Fixes ********* * ``bzr rm`` is now aliased to ``bzr del`` for the convenience of svn users. (Robert Collins, #205416) * Catch the infamous "select/poll returned error" which occurs when pycurl try to send a body request to an HTTP/1.0 server which has already refused to handle the request. (Vincent Ladeuil, #225020) * Fix ``ObjectNotLocked`` errors when using various commands (including ``bzr cat`` and ``bzr annotate``) in combination with a smart server URL. (Andrew Bennetts, #237067) * ``FTPTransport.stat()`` would return ``0000`` as the permission bits for the containing ``.bzr/`` directory (it does not implement permissions). This would cause us to set all subdirectories to ``0700`` and files to ``0600`` rather than leaving them unmodified. Now we ignore ``0000`` as the permissions and assume they are invalid. (John Arbash Meinel, #259855) * Merging from a previously joined branch will no longer cause a traceback. (Jelmer Vernooij, #203376) * Pack operations on windows network shares will work even with large files. (Robert Collins, #255656) * Running ``bzr st PATH_TO_TREE`` will no longer suppress merge status. Status is also about 7% faster on mozilla sized trees when the path to the root of the tree has been given. Users of the internal ``show_tree_status`` function should be aware that the show_pending flag is now authoritative for showing pending merges, as it was originally. (Robert Collins, #255204) * Set valid default _param_name for Option so that ListOption can embed '-' in names. (Vincent Ladeuil, #263249) * Show proper error rather than traceback when an unknown revision id is specified to ``bzr cat-revision``. (Jelmer Vernooij, #175569) * Trailing text in the dirstate file could cause the C dirstate parser to try to allocate an invalid amount of memory. We now properly check and test for parsing a dirstate with invalid trailing data. (John Arbash Meinel, #186014) * Unexpected error responses from a smart server no longer cause the client to traceback. (Andrew Bennetts, #263527) * Use a Windows api function to get a Unicode host name, rather than assuming the host name is ascii. (Mark Hammond, John Arbash Meinel, #256550) * ``WorkingTree4`` trees will now correctly report missing-and-new paths in the output of ``iter_changes``. (Robert Collins) Documentation ************* * Updated developer documentation. (Martin Pool) API Changes *********** * Exporters now take 4 parameters. (Robert Collins) * ``Tree.iter_changes`` will now return False for the content change field when a file is missing in the basis tree and not present in the target tree. Previously it returned True unconditionally. (Robert Collins) * The deprecated ``Branch.abspath`` and unimplemented ``Branch.rename_one`` and ``Branch.move`` were removed. (Jelmer Vernooij) * BzrDir.clone_on_transport implementations must now accept a stacked_on parameter. (Aaron Bentley) * BzrDir.cloning_metadir implementations must now take a require_stacking parameter. (Aaron Bentley) Testing ******* * ``addCleanup`` now takes ``*arguments`` and ``**keyword_arguments`` which are then passed to the cleanup callable as it is run. In addition, addCleanup no longer requires that the callables passed to it be unique. (Jonathan Lange) * Fix some tests that fail on Windows because files are deleted while still in use. (Mark Hammond) * ``selftest``'s ``--starting-with`` option can now use predefined prefixes so that one can say ``bzr selftest -s bp.loom`` instead of ``bzr selftest -s bzrlib.plugins.loom``. (Vincent Ladeuil) * ``selftest``'s ``--starting-with`` option now accepts multiple values. (Vincent Ladeuil) Internals ********* * A new plugin interface, ``bzrlib.log.log_adapters``, has been added. This allows dynamic log output filtering by plugins. (Robert Collins) * ``bzrlib.btree_index`` is now available, providing a b-tree index layer. The design is memory conservative (limited memory cache), faster to seek (approx 100 nodes per page, gives 100-way fan out), and stores compressed pages allowing more keys per page. (Robert Collins, John Arbash Meinel) * ``bzrlib.diff.DiffTree.show_diff`` now skips changes where the kind is unknown in both source and target. (Robert Collins, Aaron Bentley) * ``GraphIndexBuilder.add_node`` and ``BTreeBuilder`` have been streamlined a bit. This should make creating large indexes faster. (In benchmarking, it now takes less time to create a BTree index than it takes to read the GraphIndex one.) (John Arbash Meinel) * Mail clients for `bzr send` are now listed in a registry. This allows plugins to add new clients by registering them with ``bzrlib.mail_client.mail_client_registry``. All of the built-in clients now use this mechanism.
