changelog: fix readpending if no pending data exist (
issue4609)
Since transaction are used for more than just changesets, it is possible
to have a transaction without new changesets at all. In this case no
''00changelog.i.a' are written. In all cases the 'changelog.readpending'
method is called if the repository has any pending data. The 'revlog' logic
provides empty content if the file is missing, so the whole operation
resulted in an empty changelog.
We now skip reading the pending file if it is missing.
afterlock: add the callback to the top level lock (
issue4608)
If 'wlock' is taken, we should add 'afterlock' callback to the 'wlock' instead.
Otherwise, running post transaction hook after 'lock' is release but 'wlock' is
still taken lead to a deadlock (eg: 'hg update' during a hook).
This situation is much more common since:
5dc5cd7abbf5
push: acquire local 'wlock' if "pushback" is expected (BC) (
issue4596)
debuglock: access the lock file using the proper vfs
Before this fix, 'wlock' was always reported as "free" because '.hg/store/wlock'
have never been a thing.
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.

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.
