tests: add tests and document expectations from visit_children_set in rust
The tests this patch are adding have the form of formal spec in
invariants::visit_children_set::holds,
and then a series of checks that all examples must satisfy this
formal spec.
I tried to make the spec consistent with how this function is used
and how it was originally conceived. This is in conflict with how it's
documented in Rust. Some of the implementations also fail to implement
this spec, which leads to bugs, in particular when complicated patterns
are used with `hg status`.
#require test-repo
Enable obsolescence to avoid the warning issue when obsmarker are found
$ . "$TESTDIR/helpers-testrepo.sh"
Go back in the hg repo
$ cd $TESTDIR/..
$ REVSET='not public() and ::. and not desc("# no-check-commit")'
$ mkdir "$TESTTMP/p"
$ REVS=`testrepohg log -r "$REVSET" -T.`
$ if [ -n "$REVS" ] ; then
> testrepohg export --git -o "$TESTTMP/p/%n-%h" -r "$REVSET"
> for f in `ls "$TESTTMP/p"`; do
