lfs: access revlog directly
LFS is monkeypatching filelog.filelog and is then accessing
various filelog attributes in the monkeypatched function. This is all
fine.
But some of the attributes being accessed by LFS are revlog centric
and shouldn't be exposed on the file storage interface.
This commit changes the monkeypatched functions to access proxied
attributes on self._revlog instead of self.
This should be safe to do because non-revlog repositories should not
be using filelog instances: instead they should have a separate class
to represent file storage. So it is reasonable for LFS to assume the
_revlog attribute exists and points to a revlog.

Something like a virtual filesystem and/or remotefilelog. We want to be useful when not using those systems, so we do not have this method available in narrowhg proper at the moment. $ cat > "$TESTTMP/expand_extension.py" <<EOF > import os > import sys > > from mercurial import encoding > from mercurial import extensions > from mercurial import localrepo > from mercurial import match as matchmod > from mercurial import narrowspec > from mercurial import patch > from mercurial import util as hgutil > > def expandnarrowspec(ui, repo, newincludes=None): > if not newincludes: > return > import sys > newincludes = set([newincludes]) > includes, excludes = repo.narrowpats > currentmatcher = narrowspec.match(repo.root, includes, excludes) > includes = includes | newincludes > if not repo.currenttransaction(): > ui.develwarn(b'expandnarrowspec called outside of transaction!') > repo.setnarrowpats(includes, excludes) > newmatcher = narrowspec.match(repo.root, includes, excludes) > added = matchmod.differencematcher(newmatcher, currentmatcher) > for f in repo[b'.'].manifest().walk(added): > repo.dirstate.normallookup(f) > > def wrapds(ui, repo, ds): > class expandingdirstate(ds.__class__): > @hgutil.propertycache > def _map(self): > ret = super(expandingdirstate, self)._map > with repo.wlock(), repo.lock(), repo.transaction( > b'expandnarrowspec'): > expandnarrowspec(ui, repo, > encoding.environ.get(b'DIRSTATEINCLUDES')) > return ret > ds.__class__ = expandingdirstate > return ds > > def reposetup(ui, repo): > class expandingrepo(repo.__class__): > def _makedirstate(self): > dirstate = super(expandingrepo, self)._makedirstate() > return wrapds(ui, repo, dirstate) > repo.__class__ = expandingrepo > > def extsetup(unused_ui): > def overridepatch(orig, ui, repo, *args, **kwargs): > with repo.wlock(): > expandnarrowspec(ui, repo, encoding.environ.get(b'PATCHINCLUDES')) > return orig(ui, repo, *args, **kwargs) > > extensions.wrapfunction(patch, b'patch', overridepatch) > EOF $ cat >> ".hg/hgrc" <<EOF > [extensions] > expand_extension = $TESTTMP/expand_extension.py > EOF Since we do not have the ability to rely on a virtual filesystem or remotefilelog in the test, we just fake it by copying the data from the 'master' repo. $ cp -a ../master/.hg/store/data/* .hg/store/data Do that for patchdir as well. $ cp -a ../master/patchdir . `hg status` will now add outside, but not patchdir. $ DIRSTATEINCLUDES=path:outside hg status M outside/f2 $ hg tracked | grep outside I path:outside $ hg files | grep outside > /dev/null $ hg tracked | grep patchdir [1] $ hg files | grep patchdir [1] Get rid of the modification to outside/f2. $ hg update -C . 1 files updated, 0 files merged, 0 files removed, 0 files unresolved This patch will not apply cleanly at the moment, so `hg import` will break $ cat > "$TESTTMP/foo.patch" <<EOF > --- patchdir/f3 > +++ patchdir/f3 > @@ -1,1 +1,1 @@ > -this should be "patch_this", but its not, so patch fails > +this text is irrelevant > EOF $ PATCHINCLUDES=path:patchdir hg import -p0 -e "$TESTTMP/foo.patch" -m ignored applying $TESTTMP/foo.patch patching file patchdir/f3 Hunk #1 FAILED at 0 1 out of 1 hunks FAILED -- saving rejects to file patchdir/f3.rej abort: patch failed to apply [255] $ hg tracked | grep patchdir [1] $ hg files | grep patchdir > /dev/null [1] Let's make it apply cleanly and see that it *did* expand properly $ cat > "$TESTTMP/foo.patch" <<EOF > --- patchdir/f3 > +++ patchdir/f3 > @@ -1,1 +1,1 @@ > -patch_this > +patched_this > EOF $ PATCHINCLUDES=path:patchdir hg import -p0 -e "$TESTTMP/foo.patch" -m message applying $TESTTMP/foo.patch $ cat patchdir/f3 patched_this $ hg tracked | grep patchdir I path:patchdir $ hg files | grep patchdir > /dev/null
