extensions: fix documentation of disabledcmd return value

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.

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)".

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.

repair: no need to call filterunknown() in strip() Calling strip() will eventually trigger localrepo.destroyed() which will invalidate _parseroots. It will call filterunknown() upon reload. Changes to test-keyword.t are related to commit --debug running after either qpop or rollback.

test-phases: test changing null revision phase The behaviour is correct but for bad reasons: the repo.set() call in phase command fails for '-1'. It should be rejected explicitely by phase boundary commands, sadly this is hard to do because phase changes are not applied atomically.

parsers: statically initializing tp_new to PyType_GenericNew is not portable As detailed on http://docs.python.org/extending/newtypes.html (quote): "In this case, we can just use the default implementation provided by the API function PyType_GenericNew(). We’d like to just assign this to the tp_new slot, but we can’t, for portability sake. On some platforms or compilers, we can’t statically initialize a structure member with a function defined in another C module, so, instead, we’ll assign the tp_new slot in the module initialization function just before calling PyType_Ready()." Fixes "gcc (GCC) 3.4.5 (mingw-vista special r3)" complaining with: mercurial/parsers.c:1096: error: initializer element is not constant mercurial/parsers.c:1096: error: (near initialization for `indexType.tp_new')

subrepo: do not traceback on .hgsubstate parsing errors Note that aborting in subrepo.state() prevents "repairing" commands like revert to be issued.

largefiles: in putlfile, ensure tempfile's directory exists prior to creation Let R be a repo served by an hg daemon on a machine with an empty largefiles cache. Pushing a largefiles repo to R will result in a no-such-file-or-directory OSError because putlfile will attempt to create a temporary file in R/.hg/largefiles, which does not yet exist. This patch also adds a regression test for this scenario.

check-code: catch unnecessary s.strip().split() calls

tags: line.rstrip().split() can be replaced with line.split() The line looks like "123 <node> <node>" and does not start with whitespace: it was therefore not significant that rstrip was used instead of strip. Furthermore, the first part is fed to int, which will itself strip away whitespace before converting the string to an integer.

largefiles: fix "hg status dir" missing regular files (issue3421) largefiles status implementation attemps to rewrite the input match objects to match the "standins" as well as the regular files.

largefiles: make archive -S store largefiles instead of standins This is essentially a copy of largefile's override of archive() in the archival class, adapted for overriding hgsubrepo's archive(). That means decoding isn't taken into consideration, nor is .hg_archival.txt generated (the same goes for regular subrepos). Unlike subrepos, but consistent with largefile's handling of the top repo, ui.progress() is *not* called. This should probably be refactored at some point, but at least this generates the archives properly for now. Previously, the standins were ignored and the largefiles were archived only for the top level repo. Long term, it would probably be most desirable to figure out how to tweak archival's archive() if necessary such that largefiles doesn't need to override it completely just to special case the translating of standins to the real files. Largefiles will already return a context with the true largefiles instead of the standins if lfilesrepo's lfstatus is True- perhaps this can be leveraged?

subrepo/svn: cache _wcrev() value in merge()

subrepo/svn: fix checked out rev number retrieval (issue2968) The initial version was to take the "Revision" field from svn info. It works but produces false positive when parent paths are being moved or unrelated changes are being committed, causing it to change while the svn checkout itself remains the same. To avoid spurious commit, we took "Revision" and "Last Changed Rev" for general comparison and kept the latter to answer "what is your revision?" question. This is better but fails when the subrepo path exists at "Revision" but not at "Last Changed Rev". This patch adds a check for this, and returns "Revision" if the path does not exist. We try to avoid doing this as much as possible at it implies an extra, *remote* call.

amend: fix copy records handling (issue3410) Messing with the dirstate before the intermediate commit seems error prone. Instead, commit and recompute the copies with copies.pathcopies(), then use that with commitctx(). Since copies.pathcopies() does not support file replacement very well, the whole .renamed() condition in samefile() is removed and the "file replacement caused by differing copy source" effect is discarded. Test shamelessly stolen from Idan Kamara <idankk86@gmail.com>

test-commit-amend: exhibit an --amend weirdness The weirdness is --amend let you replace one file with another with same data and flags if the new file copy record differ from the one in the parent revision. In theory, there is no problem with this kind of thing, subversion supports it, but here we see log and status disagree. The reason is log reads the copy record from the filelog, while status calls copies.pathcopies() which eventually invokes some expensiveness argument to discard this case (copies.py, _forwardcopies(), line 132). Since the next patch will side with pathcopies(), I prefer to call this behaviour a bug.

localrepo: add setparents() to adjust dirstate copies (issue3407) The fix introduced in eab9119c5dee was only partially successful. It is correct to turn dirstate 'm' merge records into normal/dirty ones but copy records are lost in the process. To adjust them as well, we need to look in the first parent manifest to know which files were added and preserve only related records. But the dirstate does not have access to changesets, the logic has to moved at another level, in localrepo.
