upgrade: implement partial upgrade for upgrading persistent-nodemap
Upgrading repositories to use persistent nodemap should be fast and easy as it
requires only two things:
1) Updating the requirements
2) Writing a persistent-nodemap on disk
For both of the steps above, we don't need to edit existing revlogs.
This patch makes upgrade only do the above mentioned two steps if we are
only upgarding to use persistent-nodemap feature.
Since `nodemap.persist_nodemap()` assumes that there exists a nodemap file for
the given revlog if we are trying to call it, this patch adds `force` argument
to create a file if does not exist which is true in our upgrade case.
The test changes demonstrate that we no longer write nodemap files for manifest
after upgrade which I think is desirable.

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
