External Compatibility Breaks
*****************************
* The '.bzr/branch/email' file is no longer read to determine the users'
identity. Instead, the 'email' setting in '.bzr/branch/branch.conf'
should be used. (Jelmer Vernooij, #903894)
New Features
************
* "bzr mkdir" now includes -p (--parents) option for recursively adding
parent directories.
(Jared Hance, Jelmer Vernooij, #253529)
* ``config.Option`` can now declare ``override_from_env``, a list of
environment variables which, when set, that takes precedence over values
defined in configuration files. (Vincent Ladeuil, #907279)
Improvements
************
* New HPSS call for ``Repository.reconcile``. (Jelmer Vernooij, #894455)
* Merge now has two new hooks ``pre_merge`` and ``post_merge``
that are called before and after a merge and can make
additional modifications to the trees involved.
(Jelmer Vernooij, #906877)
* Override the value returned by ``sys.getfilesystemencoding()`` for the bzr
script to utf-8 when it would otherwise be ascii on a posix system. This
will mean bzr works with non-ascii files when no locale or an incorrect
locale is set. (Martin Packman, #794353)
* ``bzr branches`` now indicates the active colocated branch.
(Jelmer Vernooij, #891667)
* ``bzr push`` now suggests using :parent if there is a parent location
set. (Jelmer Vernooij)
* ``bzr send`` now only opens a single connection, rather than two,
to the target branch. (Jelmer Vernooij)
Bug Fixes
*********
* Allow configuration option default value to be a python callable at
registration. (Vincent Ladeuil, #832064)
* ``bzr config`` will now display the section ``[DEFAULT]`` used in
``bazaar.conf``. (Vincent Ladeuil, #907268)
* Configuration stores can now provides a specific quoting mechanism. This
is required to workaround ``configobj`` conflating quoting and list values
automatic conversion. (Vincent Ladeuil, #906897)
* Create obsolete_packs directory when repacking if it does not
exist. (Jonathan Riddell, Jelmer Vernooij, #314314)
* Fallback to the slower ``bzr log`` implementation when displaying a range
of revisions whose ancestry is not obviously on the same developement
line. (Vincent Ladeuil, #904744)
* Make lazy imports resilient when resolved concurrently from multiple
threads. Now the stand-in object will behave as a proxy for the real object
after the initial access, rather than throwing. Assigning the object to
multiple names should still be avoided. (Martin von Gagern, #396819)
* Not setting ``gpg_signing_key`` or setting it to ``default`` will use the
user email (obtained from the ``email`` configuration option or its
default value). (Vincent Ladeuil, Jelmer Vernooij, #904550)
* Prevent spurious InconsistentDelta error when committing a move of a
non-ascii directory with contents. (Rory Yorke, #185211)
* Properly ignore '\n' in an option reference since this cannot be part of a
config option identifier. (Vincent Ladeuil, #902125)
* Make sure that the bzr probers are always registered when
bzrlib.workingtree is imported. (Jelmer Vernooij, #905218)
* Report mistake trying to move a removed file with a non-ascii name without
UnicodeEncodeError being raised. (Martin Packman, #898541)
* Safely unquote configuration values in weird edge cases (a section seen as
a dictionary which is not a supported use case for the configuration
stacks). (Vincent Ladeuil, #908050)
* Stop altering ``sys.platform`` on OSX when initialising the locale.
(Martin Packman, #570495)
* Uncommit no longer removes tags if they are part of the working
trees pending merges. (Jelmer Vernooij, #905462)
API Changes
***********
* ``Config.signature_needed``, ``Config.signing_policy``,
``Config.gpg_signing_key``, ``Config.gpg_signing_command``,
``Config.checking_policy`` and ``Config.post_commit`` are now deprecated.
(Jelmer Vernooij)
* ``Repository.get_commit_builder`` now takes a ``config_stack``
rather than a ``config`` argument. (Jelmer Vernooij)
* Scripts using bzrlib should now ensure setlocale is called on posix
platforms if they need a non-ascii user encoding. (Martin Packman)
* Send formats now accept a new optional argument ``submit_branch``,
which can be None or a Branch object for the submit branch location.
(Jelmer Vernooij)
* ``VersionedFileRepository.add_revision`` no longer takes a ``config``
argument. (Jelmer Vernooij)
Internals
*********
* Add HPSS call for ``Branch.get_checkout_format``. (Jelmer Vernooij, #894459)
* Add HPSS call for ``Repository.pack``. (Jelmer Vernooij, #894461)
* Add HPSS calls for ``Repository.iter_files_bytes``, speeding up
several commands including ``bzr export`` and ``bzr co --lightweight``.
(Jelmer Vernooij, #608640)
* All bzr control directories, branch formats, repository formats and
working tree formats now support feature flags, which are
serialized in their respective format files. See
``doc/developers/feature-flags.txt`` for details.
(Jelmer Vernooij)
* ``bzrlib.urlutils`` now includes ``quote`` and ``unquote`` functions,
rather than importing them from ``urllib``. This prevents loading
of the ``socket``, ``ssl`` and ``urllib`` modules for
local bzr operations. (Jelmer Vernooij)
* Configuration options can be SI units by using ``int_SI_from_unicode`` as
their ``convert_from_unicode`` helper. (Vincent Ladeuil)
* Configuration stacks can now use ``StartingPathMatcher`` to select the
sections matching a location while respecting the order chosen by the user
in the configuration file: from generic sections to specific
sections. (Vincent Ladeuil, #832046).
* Configuration stores can now save incremental changes by using
``save_changes()`` instead of ``save()``. This reduces the number or
required input/outputs and allows stores to be shared between
stacks. (Vincent Ladeuil)
* ControlDir now has a get_branches method that returns a dictionary
whose keys are the names of the branches and whose values are the
branches themselves. The active branch uses the key None.
(Neil Martinsen-Burrell)
* Helper ``osutils.path_from_environ`` added for extracting a unicode path
from an environment variable. (Martin Packman, #832028)
* Helper ``win32utils.get_environ_unicode`` added for avoiding encoding
problems with ``os.environ.get`` use. (Martin Packman, #262874)
* Lazy imports can now only be absolute. (Jelmer Vernooij)
* Merge3Mergers now have an optional ``other_branch`` argument
which contains the branch from which the ``other_tree``
was obtained, if any. (Jelmer Vernooij)
* MutableTree now has a hook ``post_build_tree`` which is called after
a new mutable tree has been created. (Jelmer Vernooij, #912765)
* New HPSS call ``BzrDir.checkout_metadir``. (Jelmer Vernooij, #894459)
* New HPSS call ``VersionedFileRepository.get_inventories``,
speeding up various commands including ``bzr export``,
``bzr checkout`` and ``bzr cat``. (Jelmer Vernooij, #608640)
* The ``ConfigCommandLineStore`` is now supported by ``bzr config`` and is
seen as single no-name section of configuration options. (Vincent Ladeuil)
Testing
*******
* New matcher ``ContainsNoVfsCalls`` which filters a list of HPSS
calls for VFS requests. (Jelmer Vernooij)
* New ``MemoryStack`` class allows for diskless tests and locally injected
configuration stacks. Lower level tests for predefined set of options can
be written without setting up configuration files. (Vincent Ladeuil)
