largefiles: mark lfile as added in lfdirstate when the standin is added
This is an alternative solution to the problem addressed by
f72d73937853. This
implementation has the advantage that it doesn't mark clean largefiles as
normallookup. We can thus avoid repeated rehashing of all largefiles when
f72d73937853 is backed out.
This implementation use the existing 'lfmr' actions that
23fe278bde43
introduced for handling another part of the same cases.
tests: add test coverage for lfdirstate invalidation of linear update
f72d73937853 introduced a significant performance regression: All largefiles
are marked 'normallookup' in lfdirstate by linear (or noop) updates and has to
be rehashed by the next command.
To avoid such regressions, keep an eye on the dirstate content after a plain
'hg up'.
test-subrepo-git: ignore global git config
This was causing a test failure for people with company-wide settings.
Still need a way to ignore local config.
tests/autodiff.py: explicitly only honor feature diffopts
This test extension manages the opts it cares about on its own anyway.
cmdutil.changeset_printer: explicitly honor all diffopts
This is used in hg log -p so the output is expected to be the same as that of
hg diff.
export: explicitly honor all diffopts
This is slightly more controversial than diff, but we hope that HGPLAIN=1
covers all the format-breaking ones.
A possible alternative here that breaks BC is to honor all opts except the
whitespace ones.
webcommands.annotate: explicitly only honor whitespace diffopts
The whitespace ones are the only ones the annotate logic cares about anyway, so
there's no visible impact.
filectx.parents: filter nullrev parent sooner
We are going to introduce a linkrev-correction phases when computing parents.
It will be more convenient to have the nullid parent filtered out earlier. I
had to make a minimal adjustment to the rename handling logic to keep it
functional. That logic have been documented in the process since it took me
some time to check all the cases out.
