manifest: move pure parsing code out of pure
This lets us transition more smoothly.
manifest.c: new extension code to lazily parse manifests
This lets us iterate manifests in order, but do a _lot_ less work in
the common case when we only care about a few manifest entries.
Many thanks to Mike Edgar for reviewing this in advance of it going
out to the list, which caught many things I missed.
This version of the patch includes C89 fixes from Sean Farley and
many correctness/efficiency cleanups from Martin von
Zweigbergk. Thanks to both!
workingctx: use normal dirs() instead of dirstate.dirs()
The workingctx class was using dirstate.dirs() as it's implementation. The
sparse extension maintains a pruned down version of the dirstate, so this
resulted in the workingctx reporting an incorrect listing of directories
during merge calculations (it was detecting directory renames when it
shouldn't have).
The fix is to use the default implementation, which uses workingctx._manifest,
which unions the manifest with the dirstate to produce the correct overall
picture. This also produces more accurate output since it will no longer
return directories that have been entirely deleted in the dirstate.
Tests will be added to the sparse extension to detect regressions for this.
subrepo: always return scmutil.status() from gitsubrepo.status()
This was accidentally left out of
c95db3208a33.
subrepo: explicitly request clean and unknown files in status for git's add
No behavior changes here since gitsubrepo.status() doesn't currently populate
clean, and ignores whether unknown files were actually requested. But this is
in line with other calls to status, and should avoid future surprises.
largefiles: handle logging from outside the repo
It's probably possible to refactor so that the 'if m._cwd' check isn't
necessary, but the False case is the typical case (i.e. run from the root of the
repo), and simpler to read.
An exact path to a largefile from outside the repo was previously ignored.
match.rel('.hglf') will handle figuring out both the correct '../' length to the
standin directory if inside the repo, or path/to/repo from outside, at the cost
of a pconvert() to keep the patterns using '/' on Windows.
