bzr 1.8rc1
Bazaar
bzr 1.8rc1
Changes
- bzr log file has been changed. It now uses a different method
for determining which revisions to show as merging the changes to
the file. It now only shows revisions which merged the change
towards your mainline. This simplifies the output, makes it faster,
and reduces memory consumption. (John Arbash Meinel)
- bzr merge now defaults to having --reprocess set, whenever
--show-base is not supplied. (John Arbash Meinel)
- bzr+http// will now optionally load plugins and write logs on the
server. (Marius Kruger)
- bzrlib._dirstate_helpers_c.pyx does not compile correctly with
Pyrex 0.9.4.1 (it generates C code which causes segfaults). We
explicitly blacklist that version of the compiler for that
extension. Packaged versions will include .c files created with
pyrex >= 0.9.6 so it doesn’t effect releases, only users running
from the source tree. (John Arbash Meinel, #276868)
Features
- bzr is now compatible with python-2.6. python-2.6 is not yet officially
supported (nor released, tests were conducted with the dev version of
python-2.6rc2), but all known problems have been fixed. Feedback
welcome.
(Vincent Ladeuil, #269535)
Improvements
- bzr annotate will now include uncommitted changes from the local
working tree by default. Such uncommitted changes are given the
revision number they would get if a commit was done, followed with a
? to indicate that its not actually known. (Robert Collins, #3439)
- bzr branch now accepts a --standalone option, which creates a
standalone branch regardless of the presence of shared repositories.
(Daniel Watkins)
- bzr push is faster in the case there are no new revisions to
push. It is also faster if there are no tags in the local branch.
(Andrew Bennetts)
- File changes during a commit will update the tree stat cache.
(Robert Collins)
- Location aliases can now accept a trailing path. (Micheal Hudson)
- New hooks Lock.hooks when LockDirs are acquired and released.
(Robert Collins, MartinPool)
- Switching in heavyweight checkouts uses the master branch’s context, not
the checkout’s context. (Adrian Wilkins)
- status on large trees is now faster, due to optimisations in the
walkdirs code. Of particular note, the walkdirs code now performs
a temporary chdir() while reading a single directory; if your
platform has non thread-local current working directories (and is
not windows which has its own implementation), this may introduce a
race condition during concurrent uses of bzrlib. The bzrlib CLI
will not encounter this as it is single threaded for working tree
operations. (Robert Collins)
- The C extensions now build on python 2.4 (Robert Collins, #271939)
- The -Dhpss debug flag now reports the number of smart server
calls per medium to stderr. This is in addition to the existing
detailed logging to the .bzr.log trace file. (Andrew Bennetts)
Bug Fixes
- Avoid random failures arising from misinterpreted errno values
in _readdir_pyx.read_dir.
(Martin Pool, #279381)
- Branching from a shared repository on a smart server into a new
repository now preserves the repository format.
(Andrew Bennetts, #269214)
- bzr log now accepts a --change option.
(Vincent Ladeuil, #248427)
- bzr missing now accepts an --include-merges option.
(Vincent Ladeuil, #233817)
- Don’t try to filter (internally) ‘.bzr’ from the files to be deleted if
it’s not there.
(Vincent Ladeuil, #272648)
- Fix ‘_in_buffer’ AttributeError when using the -Dhpss debug flag.
(Andrew Bennetts)
- Fix TooManyConcurrentRequests errors caused by a connection failure
when doing bzr pull or bzr merge from a bzr+ssh URL.
(Andrew Bennetts, #246233)
- Fixed bzr st -r branch:PATH_TO_BRANCH where the other branch
is in a different repository than the current one.
(Lukáš Lalinský, #144421)
- Make the first line of the manpage preamble a comment again.
(David Futcher, #242106)
- Remove use of optional parameter in GSSAPI FTP support, since
it breaks newer versions of Python-Kerberos. (Jelmer Vernooij)
- The autopacking logic will now always create a single new pack from
all of the content which it deems is worth moving. This avoids the
‘repack a single pack’ bug and should result in better packing
overall. (John Arbash Meinel, #242510, #172644)
- Trivial documentation fix.
(John Arbash Meinel, #270471)
- bzr switch and bzr bind will now update the branch nickname if
it was previously set. All checkouts will now refer to the bound branch
for a nickname if one was not explicitly set.
(Marius Kruger, #230903)
Documentation
- Explain revision/range identifiers. (Daniel Clemente)
API Changes
- CommitBuilder.record_entry_contents returns one more element in
its result tuple - an optional file system hash for the hash cache
to use. (Robert Collins)
- dirstate.DirState.update_entry will now only calculate the sha1
of a file if it is likely to be needed in determining the output
of iter_changes. (Robert Collins)
- The PackRepository, RepositoryPackCollection, NewPack classes have a
slightly changed interface to support different index types; as a
result other users of these classes need to supply the index types
they want. (Robert Collins)
Testing
- bzrlib.tests.repository_implementations has been renamed to
bzrlib.tests.per_repository so that we have a common structure
(and it is shorter). (John Arbash Meinel, #239343)
- LocalTransport.abspath() now returns a drive letter if the
transport has one, fixing numerous tests on Windows.
(Mark Hammond)
- PreviewTree is now tested via intertree_implementations.
(Aaron Bentley)
- The full test suite is passing again on OSX.
(Guillermo Gonzalez, Vincent Ladeuil)
- The full test suite passes when run with -Eallow_debug.
(Andrew Bennetts)
Internals
- A new hook, Branch.open, has been added, which is called when
branch objects are opened. (Robert Collins)
- bzrlib.osutils._walkdirs_utf8 has been refactored into common
tree walking, and modular directory listing code to aid future
performance optimisations and refactoring. (Robert Collins)
- bzrlib.trace.debug_memory can be used to get a quick memory dump
in the middle of processing. It only reports memory if
/proc/PID/status is available. (John Arbash Meinel)
- New method RevisionSpec.as_tree for representing the revision
specifier as a revision tree object. (Lukáš Lalinský)
- New race-free method on MutableTree get_file_with_stat for use
when generating stat cache results. (Robert Collins)
- New win32utils.get_local_appdata_location() provides access to a local
directory for storing data. (Mark Hammond)
- To be compatible with python-2.6 a few new rules should be
observed. ‘message’ attribute can’t be used anymore in exception
classes, ‘sha’ and ‘md5’ modules have been deprecated (use
osutils.[md5|sha]), object__init__ and object.__new__ don’t accept
parameters anymore.
