parsers: strictly check for 20-byte hashes where they're required

templater: handle SyntaxError when parsing ui.logtemplate Before, Mercurial would crash with a traceback ending with SyntaxError: unmatched quotes if you configured [ui] logtemplate = {rev}\n The SyntaxError is now catched and the string is re-parsed without requiring quotes.

i18n-pt_BR: synchronized with 95ca6c8b38da

progress: fix indentation

test-progress: fix whitespace typo

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

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.

mq: add --no-backup for qpush/qpop/qgoto

mq: backup local changes in qpush --force qpush help says the following about --force: 1- When -f/--force is applied, all local changes in patched files will be lost. 2- Apply on top of local changes In practice, qpush --force will attempt to apply the patch on top of local changes, and on success will merge them in the pushed patch. On failure, patched files will contain a mix of local changes (where the patch could not apply) and a mix of patch changes (were it applied). So, local changes are less lost than entangled with a mass of other changes. This patch makes qpush --force backup all locally modified files touched by the next patch being applied. When multiple patches are being pushed, this logic is repeated for each patch. Note that modified but successfully patched files are preserved as well.

mq: backup local changes in qpop --force (issue3433)

pager: remove quiet flag With the pager running as a child process, exiting the pager doesn't result in a broken pipe message. To distinguish the exit broken pipe code from a mercurial abort we register the default action for SIGPIPE. This results in a 141 exit code instead of a 255. On windows SIGPIPE doesn't exists and a ValueError will be thrown.

pager: preserve Hg's exit code (and fix Windows support) (issue3225) This changes how the pager extension invokes the pager. Prior to this change, the extension would fork Hg and exec the pager in the parent process. This loses Hg exit code, and it doesn't work on Windows. Now the pager is invoked using the subprocess library, and an atexit handler is registered that makes Hg wait for the pager to exit before it exits itself. Note that if you exit the pager before Hg is done running, you'll get an exit code of 255, which is caused by Python blowing up due to a broken pipe. If you set pager.quiet=True, you'll get the OS-level return code of 141.

amend: preserve extra dict (issue3430)

parser: use PyInt_FromSsize_t in index_stats Eliminates mercurial/parsers.c(515) : warning C4244: 'function' : conversion from 'Py_ssize_t' to 'long', possible loss of data mercurial/parsers.c(520) : warning C4244: 'function' : conversion from 'Py_ssize_t' to 'long', possible loss of data mercurial/parsers.c(521) : warning C4244: 'function' : conversion from 'Py_ssize_t' to 'long', possible loss of data when compiling for Windows x64 target using the Microsoft compiler. PyInt_FromSsize_t does not exist for Python 2.4 and earlier, so we define a fallback in util.h to use PyInt_FromLong when compiling for Python 2.4.

localrepo: cleanup var names and comments Cosmetic cleanups. Fix comment typo referring to the notion of multiple tips. Make variable describing a generator end in 'gen'. Fix another var containing a node not to end with 'rev'.

transplant: manually transplant pullable changesets with --log

phases: stop modifying localrepo in writeroots() Also pass the phaseroots being written for clarity. repo._dirtyphases was already reset to False at call site.

phases: stop modifying localrepo in readroots() phasedefaults is also passed explicitely to help the casual reader understand where it is used without grepping all the sources.

phases: call filterunknown() in readroots() One less function manipulating localrepo state.
