perf: allow profiling of more than one run
By default, we still profile the first run only. However profiling more run help
to understand side effect from one run to the other. So we add an option to be
able to do so.
Same with share-safe
$ echo "[format]" >> $HGRCPATH
$ echo "use-share-safe = True" >> $HGRCPATH
$ cd $TESTTMP
$ hg init myrepo
$ cd myrepo
$ cat > .hg/hgrc <<EOF
> [extensions]
> sparse=
> EOF
$ echo a > show
$ echo x > hide
$ hg ci -Aqm 'initial'
Regression test: checks that this command correctly locks the store
before updating the store [requirements] config.
$ hg up -q 0
$ hg debugsparse --include 'hide'
