copies: add an devel option to trace all files
Filelog based copy tracing only trace copy for file that have been added. This
is a trade off between skipping some rare copy case in exchange for avoiding
atrocious-to-the-point-of-unusable performance.
The changeset centric copy tracing does not need this trade off and naturally
trace all copy, include the one involving non-new files.
In order to ease the comparison from both algorithm, we add a small devel option
to trace copy for all files in the target revisions.

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
