phases: avoid a potentially costly dictionary interation in some case
If we retract for the draft phase, there is not non-public item to be retracted
and we can skip this part. This part is was apparently super costly thanks to
Python.
On mozilla-try-2019-02-18, a perf::unbundle call with a 10 000 changesets
bundle gives give use the following timing.
e57d4b868a3e: 4.6 seconds
ac1c75188440: 102.5 seconds
this-changeset: 30.0 seconds
So we recovered about ⅔ of the regression, the next changeset will give us the
rest back.

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
