mq: use exact matching in the second dirstate walking for efficiency of 'qnew' 'hg qnew' with pattern/-I/-X creates matching object with them, and uses it twice for 'dirstate.walk()': via 'repo.status()' and 'repo.commit()'. this may cause full manifest scan in the second 'dirstate.walk()', even though mq already knows complete target filenames at the first 'dirstate.walk()'. this patch creates exact matching object also in this case, and use it at 'repo.commit()' invocation to avoid full manifest scan in the second 'dirstate.walk()'. even though 'inclsubs' is added to 'pats' for original matching object, it is also passed to exact matching object, because subrepositories are deleted from result of 'dirstate.walk()' at the end of it.

tests: avoid test-hup hanging on AIX test-hup hangs on AIX. Under ksh89 on AIX (the default shell), echo Hello; while [ ! -s not-there ]; do true; done produces no output while the loop executes. Replacing 'true' with 'sleep 0' fixes, as does using a less broken shell. ksh93 is fine. Update check-code.py to look for this, and make same change in test-serve.t. In fact test-serve works fine, probably because of additional commands between echo and the loop, but that's a subtlety not easy to test for.

parsers: incrementally parse the revlog index in C We only parse entries in a revlog index file when they are actually needed, and cache them when first requested. This makes a huge difference to performance on large revlogs when accessing the tip revision or performing a handful of numeric lookups (very common cases). For instance, "hg --time tip --template {node}" on a tree with 300,000 revs takes 0.15 before, 0.02 after. Even for revlog-intensive operations (e.g. running "hg log" to completion), the lazy approach is about 1% faster than the eager parse_index2.

mdiff: fix diff header generation for files with spaces (issue3357) diff ---/+++ should end filenames with a TAB when they contain spaces. Current code failed to do so when only the +++ file had spaces. This only happened with git renames from a name without space to one with space.

protocol: Add the stream-preferred capability This makes the client use the uncompressed protocol.

templates/filters: extracting the user portion of an email address Currently, the 'user' filter is using util.shortuser(text) (which clearly doesn't extract only the user portion of an email address, even though the help text says it does). The new 'emailuser' filter uses the new util.emailuser(text) function which, instead, does exactly that. The help text on the 'user' filter has been modified accordingly.

context: make changectx.mutable() benefit from .phase() logic This fixes "hg qimport -r null". Previous versions used to: - Traceback because null revision mutability was not defined - Add an empty -1.diff patch to the series The error message: abort: revision -1 is not mutable is symptomatic of a deeper problem in phase command revision handling. It could be fixed easily in the command itself but I feel a better fix must be done in phase API which raises the issue of phase updates atomicity: aborting in phases.advanceboundary/retractboundary requires a better rollback behaviour to avoid partial changes.

patch: remove useless variable assignment

export: catch exporting empty revsets (issue3353) Additionally add tests for empty revsets and unknown revisions.

test-merge-types: allow different output with existing hgmerge (issue3346) Because hgmerge was meant to be adjusted to personal needs, there may be many remaining copies in people's $PATH.

inotify: catch SignalInterrupt during shutdown (issue3351) When inotify.repowatcher.shutdown() is called, mercurial.error.SignalInterrupt exception is thrown by mercurial.dispatch._runcatch.catchterm(), therefore socketlistener.shutdown() is not called. Catching this allows cleanup action (removing the socket file) to proceed.

clone: always close source repository (issue2491) This is especially needed for cloning from bundles as a temporary bundlerepository is created which needs to be deleted after clone has finished.

tests: make tests work if directory contains special characters With this quoting tests will work e.g. in "/tmp/foo bar/mercurial/".

test-gpg: replace 825565136235 by md5sum check The call to 'hg identify' would have needed '--cwd "$TESTDIR' to make it work anyway, but by using a checksum this test can work outside a repository.

config: discard UTF-8 BOM if found

tests: shorten post-test sleeps This helps expose races

tests: don't run test-gpg if not in a working directory test-gpg has to be run in a mercurial working directory as it uses that to verify that it hasn't modified the trustdb.gpg file. Skip the test if it is running in an exploded tarball.

tests: avoid zombie lockup with test-hup The 'while kill -0' recipe can cause a livelock if the process we're waiting to die is a normal child process. If it becomes a zombie that the shell doesn't reap (shell bug?), it will continue to be able to accept signals. So instead, we just wait(1).

tests: make test-hup more race-proof We need to wait until a journal exists AND is non-empty before aborting a transaction to get stable output. We move the kill wait outside the fifo block to avoid potential deadlock.
