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.  (Neil Martinsen-Burrell)
