narrow: use narrow_widen wireproto command to widen in case of ellipses
Few releases ago, we introduce narrow_widen wireproto command to be used to widen
narrow repositories. Before this patch, that was used in non-ellipses cases
only. In ellipses cases, we still do exchange.pull() which can pull more data
than required.
After this patch, the client will first check whether server supports doing
ellipses widening using wireproto command or not by checking server's wireproto
capability. If the server is upto date and support latest ellipses capability,
we call the wireproto command. Otherwise we fallback to exchange.pull() like
before.
The compat code make sure that things works even if one of the client or server
is old. The initial version of this patch does not had this compat code. It's
added to help Google release things smoothly internally. I plan to drop the
compat code before the upcoming major release.
Due to change to wireproto command, the code looks a bit dirty, next patches
will clean that up.

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 > > narrowspecexpanded = False > def expandnarrowspec(ui, repo, newincludes=None): > if not newincludes: > return > if getattr(repo, '_narrowspecexpanded', False): > return > repo._narrowspecexpanded = True > 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) > narrowspec.copytoworkingcopy(repo) > 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 reposetup(ui, repo): > class expandingrepo(repo.__class__): > def narrowmatch(self, *args, **kwargs): > with repo.wlock(), repo.lock(), repo.transaction( > b'expandnarrowspec'): > expandnarrowspec(ui, repo, > encoding.environ.get(b'DIRSTATEINCLUDES')) > return super(expandingrepo, self).narrowmatch(*args, **kwargs) > 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
