tests: unify the last sh tests This requires a slightly smarter check-code check for sed output filtering.

tests: run most check-code sh checks on continued lines too Some false errors are degraded to warnings and whitelisted.

revlog: speed up prefix matching against nodes The radix tree already contains all the information we need to determine whether a short string is an unambiguous node identifier. We now make use of this information. In a kernel tree, this improves the performance of "hg log -q -r24bf01de75" from 0.27 seconds to 0.06.

parsers: ensure that nullid is always present in the radix tree

parsers: allow hex keys

revset: add function for matching extra data (issue2767)

graft: implement --log (issue3438)

phase: make if abort on nullid for the good reason The good reason being you cannot call retractboundary() on nullid, not revset.set() cannot resolve '-1'.

phases: make advance/retractboundary() atomic Before this, if advanceboundary() failed after updating some roots but before calling retractboundary(), the phase cache would be left in an invalid state, marked dirty, and written as such. This patch approach is to turn advance/retractboundary() into phasecache methods, then operate on copies and merge them back on success. With the same technique, we can ensure the atomicity of combinations of advance/retractboundary() calls, like those performed in changegroup handling code.

phases: introduce phasecache The original motivation was changectx.phase() had special logic to correctly lookup in repo._phaserev, including invalidating it when necessary. And at other places, repo._phaserev was accessed directly. This led to the discovery that phases state including _phaseroots, _phaserev and _dirtyphase was manipulated in localrepository.py, phases.py, repair.py, etc. phasecache helps encapsulating that. This patch replaces all phase state in localrepo with phasecache and adjust related code except for advance/retractboundary() in phases. These still access to phasecache internals directly. This will be addressed in a followup.

mq: introduce mq.check setting When: [mq] check = True is set, qpush, qpop and qgoto behave as if -c/--check were passed. If incompatible options like -f/--force or --exact are set, this setting is ignored. This setting enables what many users expect mq default behaviour to be.

mq: introduce qgoto --check

mq: introduce qpush --check qpush --check let you qpush with uncommitted files not overlapping patched files.

mq: introduce qpop --check qpop --check let you qpop with uncommitted files if they do not intersect with files touched by the popped patches.

pager: check if signal.SIGPIPE exists We have to check for signal.SIGPIPE before we attempt to set it.

diffhelpers: harden testhunk

patch: fix segfault against unified diffs which start line is zero Since 2b1ec74c961f, if a chunk starts with "@@ -0,1", oldstart turns into a negative value. Because diffhelpers.testhunk() doesn't expect negative bstart, it bypasses "alen > blen - bstart" condition and segfaults at "PyList_GET_ITEM(b, i + bstart)".

bugzilla: fix transport initialization on python 2.4

bisect: set HG_NODE when runing a command When running a command, set the environment variable HG_NODE to tell the command which changeset is being visited.

bisect: track the current changeset (issue3382) Introduce a new revset feature, bisect(current), that identifies the changeset currently being bisected.

localrepo: optimize internode status calls using withflags Introduce manifestdict.withflags() to get a set of all files which have any flags set, since these are likely to be a minority. Otherwise checking .flags() for every file is a lot of dictionary lookups and is quite slow.

localrepo: optimize internode status calls using match.always Introduce match.always() to check if a match object always says yes, i.e. None was passed in. If so, mfmatches should not bother iterating every file in the repository.
