status: pass matcher to pathcopies() Just like a7f8e3584ef3 (diff: pass the diff matcher to the copy logic, 2015-04-16) sped up 'hg diff --git $path', let's speed up 'hg st -C $path'. On the Firefox repo, this speeds up hg st --rev tip~40000 --rev tip -C python from 16s to 1.8s. Those two revisions differ in 100k files, out of which 1k is in python/.

annotate: prepare ancestry context of workingfilectx _ancestrycontext is necessary for fast lookup of _changeid. Because we can't compute the ancestors from wctx, we skip to its parents. 'None' is not needed to be included in _ancestrycontext because it is used for a membership test of filelog revisions. repo: https://hg.mozilla.org/releases/mozilla-beta/#062e49bcb2da command: hg annotate -r 'wdir()' gfx/thebes/gfxWindowsPlatform.cpp before: 51.520 sec after: 1.780 sec

committablefilectx: propagate ancestry info to parent to fix annotation Before this patch, annotating working directory could include wrong revisions that were hidden or belonged to different branches. This fixes wfctx.parents() to set _descendantrev so that all ancestors can take advantage of the linkrev adjustment introduced at c48924787eaa. _adjustlinkrev() can handle 'None' revision thanks to 5a12ef618c03.

filectx: extract function to create parent fctx keeping ancestry info committablefilectx.parents() should use this to take advantage of the linkrev adjustment.

filectx: factor out creation of parent fctx This series tries to fix wrong ancestry information on annotating working directory. This change should slightly improves the readability of the next patch.

help: fix typo commited -> committed

largefiles: don't mangle filesets when fixing up the log matcher The fileset-generated.t test previously failed with this: + hg: parse error: unknown identifier: .hglf/modified + (did you mean 'modified'?) + [255] Filesets will find the standins on their own, without any help. While that's useful for some things like modified(), clean(), etc., it is wrong for things like size(). Proper fileset support for largefiles is not trivial, but this was failing with just the extension enabled on a normal repo.

largefiles: don't crash when cloning to a remote repo The immediate crash was when checking for requirements immediately after this, but lfcommands.downloadlfiles() will also crash if --all-largefiles is specified. That has been in place since atleast 5884812686f7 (2.3-rc) without anyone noticing. I can't tell from the peer classes if there's a way to make the custom largefile functionality work in this case, but atleast it doesn't crash.

run-tests: don't error when glob matched line ends with backslash As part of writing another test, I triggered an array index error in glob match processing code by having a (glob) line end in a single backslash (which is the escape character). Adding a simple bounds check prevents the error in run-tests.py.

histedit: change state format to allow non-hash lines The existing state serialization format assumed the rule line consisted of an action and a hash. In our external extension that adds 'exec' this is not the case (there is no hash, just the shell command). So let's change the format to be more generic with just an action and a remainder, and the various commands can handle it as they wish. Flagged for stable since we want to get this format tweak in before the new format goes live in the release.
