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.

Testing that convert.hg.preserve-hash=true can be used to make hg convert from hg repo to hg repo preserve hashes, even if the computation of the files list in commits change slightly between hg versions. $ cat <<'EOF' >> "$HGRCPATH" > [extensions] > convert = > EOF $ cat <<'EOF' > changefileslist.py > from mercurial import (changelog, extensions, metadata) > def wrap(orig, clog, manifest, files, *args, **kwargs): > files = metadata.ChangingFiles(touched=[b"a"]) > return orig(clog, manifest, files, *args, **kwargs) > def extsetup(ui): > extensions.wrapfunction(changelog.changelog, 'add', wrap) > EOF $ hg init repo $ cd repo $ echo a > a; hg commit -qAm a $ echo b > a; hg commit -qAm b $ hg up -qr 0; echo c > c; hg commit -qAm c $ hg merge -qr 1 $ hg commit -m_ --config extensions.x=../changefileslist.py $ hg log -r . -T '{node|short} {files|json}\n' c085bbe93d59 ["a"] Now that we have a commit with a files list that's not what the current hg version would create, check that convert either fixes it or keeps it depending on config: $ hg convert -q . ../convert $ hg --cwd ../convert log -r tip -T '{node|short} {files|json}\n' b7c4d4bbacd3 [] $ rm -rf ../convert $ hg convert -q . ../convert --config convert.hg.preserve-hash=true $ hg --cwd ../convert log -r tip -T '{node|short} {files|json}\n' c085bbe93d59 ["a"] $ rm -rf ../convert
