tests: remove test-pull-pull-corruption2.t This test gave random failures on slow machines (solaris). The test was added in 6f6e210b38cf as a test case from issue148. It did however require manual setup: The attached script creates such a corruption (you have to add a "import time; time.spleep(3)" in localrepo.addchangegroup before the changegroup manifest are written for example. The test as it is has thus no value as automatic test case. The necessary sleep could be added by a hook, but test-pending.t already tests that.

tests: remove race in test-pull-pull-corruption.t The output from the background process was not always interleaved "correctly" with output from the foreground process.

tests: fix bashism in test-convert-splicemap.t This should have been caught by check-code.

opener: coding style, use triple quotes for doc string

icasefs: make case-folding collision detection as rename aware (issue3370) if the file in target context causes case-folding collision against one in working context, current implementation aborts merging with it, even thouhg collding one (in target) is the file renamed from collided one (in working). this patch uses file copy information to know whether colliding file is renamed from collided one or not: if so, collision between them is ignored. this patch also avoids collision detection between current context and target context, if working context is clean (with --check/-c) or will be clean (with --clean/-C).

bdiff.bdiff: release the GIL before doing expensive diff operations This means that threaded webservers will have more of a chance of doing something useful while the C extension is busy computing a delta. Not doing this was causing problems for Google Code with a 25 meg text file that takes O(7 minutes) to deltify.

fetch: remove confusing reference to "authoritative" changes

patch: be more tolerant with "Parent" header (issue3356) Here is how export and mq write the "Parent" header: mq: # Parent XXXXX export: # Parent XXXXX then import expects exactly 2 spaces while mq tolerates one or more. So "hg import --exact" truncates mq generated patches header by one character and fails. This patch aligns import "Parent" header parsing on mq one. I do not expect spaces in parent references anytime soon. Reported by Stefan Ring <stefanrin@gmail.com>

pure/osutil: use Python's msvcrt module (issue3380) As proposed by Christophe Gouiran <christophe.gouiran@eurocopter.com>

commands: add missing wlock to graft

dirstate: write branch file atomically

commands: add missing wlock to backout

i18n: show localized messages for commands/extensions in hgweb help top (issue3383) in hgweb help top page, help topics are localized, but abstracts of commands and extensions are not, although these are already translated. it is because localized messages for them should be explicitly looked up by original ones. this patch looks localized messages up for each commands/extensions.

revert: show warning when reverting subrepos that do not support revert The warning is similar to the warning that was shown before hgsubrepo revert support was added, with the exception that now the subrepo type is shown. For example, when trying to revert a git subrepo located in "include/mygitsub", the warning message would be: include/mygitsub: reverting git subrepos is unsupported

revset: fix O(n**2) behaviour of bisect() (issue3381)

convert/svn: do not try converting empty head revisions (issue3347) Subversion conversion works by picking trunk and branches heads, computing a revision graph from them and converting the selected commits. By design we fail to convert empty revisions so we have to be careful when discovering the revision graph. In this particular issue, the source svn repository was a partial mirror made by svnsync. The funny part is svnsync preserves all revisions including empty ones. Also, we trusted ra.stat(path, stop).created_rev to give us the latest revision with changes in path history up to stop. This assumption broke at least when path is '', that is the repository root, which always returned 'stop' revision despited being empty. The workaround is to first trust ra.stat() but if the returned revision appear empty, search the whole path history from stop to r1 until some changes are found.

convert/svn: refactor svn_source.latest() with a nested function We will call it more than once for reasons detailed later.

convert/svn: clarify svn_source.latest() stop arg default value stop=0 could pass for a valid default value at first sight.

factotum: rename mount and path configuration entries The factotum extension used mount and path entries which were too generic. These have been replaced by mountpoint and executable (respectively) to match existing conventions.

Added signature for changeset d9e2f09d5488

Added tag 2.2-rc for changeset d9e2f09d5488

Makefile: be more careful when cleaning up pure/ components The recent introduction of pure/__init__.py causes mercurial/__init__.py to get clobbered by make clean.

merge default into stable for 2.2 code freeze

commit: add option to amend the working dir parent The --amend flag can be used to amend the parent of the working directory with a new commit that contains the changes in the parent in addition to those currently reported by "hg status", if there are any. The old commit is stored in a backup bundle in ".hg/strip-backup"(see "hg help bundle" and "hg help unbundle" on how to restore it). Message, user and date are taken from the amended commit unless specified. When a message isn't specified on the command line, the editor will open with the message of the amended commit. It is not possible to amend public changesets (see "hg help phases") or changesets that have children. Behind the scenes, first commit the update (if there is one) as a regular child of the current parent. Then create a new commit on the parent's parent with the updated contents. Then change the working copy parent to this new combined changeset. Finally, strip the amended commit and update commit created in the beginning. An alternative (cleaner?) approach of doing this is suggested here: http://selenic.com/pipermail/mercurial-devel/2012-March/038540.html It is currently not possible to amend merge commits or recursively, this can be added at a later time.

transplant: remove extraneous whitespace

journal: use tryread helper to backup files (issue3375)

opener: introduce tryread helper This makes it easier to follow the common pattern "read a file or give an empty string if it's missing".

tests: add test for fileset 'subrepo' keyword

revset: make matching() work on python 2.4 tuple.index() was apparently added to python 2.6: http://bugs.python.org/issue1696444 Also remove a trailing comma to make check-code.py happy.
