discovery: avoid wrong detection of multiple branch heads (issue6256)
This fix the code using obsolescence markers to remove "to be obsoleted" heads
during the detection of new head creation from push. The code turned out to not
use the branch information at all. This lead changeset from different branch to
be detected as new head on unrelated branch.
The code fix is actually quite simple. New tests have been added to covers
these cases.

Checking how hg behaves when one side of a pull/push doesn't support some capability (because it's running an older hg version, usually). $ hg init repo1 $ cd repo1 $ echo a > a; hg add -q a; hg commit -q -m a $ hg bookmark a $ hg clone -q . ../repo2 $ cd ../repo2 $ touch $TESTTMP/disable-lookup.py $ disable_cap() { > rm -f $TESTTMP/disable-lookup.pyc # pyc caching is buggy > cat <<EOF > $TESTTMP/disable-lookup.py > from mercurial import extensions, wireprotov1server > def wcapabilities(orig, *args, **kwargs): > cap = orig(*args, **kwargs) > cap.remove(b'$1') > return cap > extensions.wrapfunction(wireprotov1server, '_capabilities', wcapabilities) > EOF > } $ cat >> ../repo1/.hg/hgrc <<EOF > [extensions] > disable-lookup = $TESTTMP/disable-lookup.py > EOF $ cat >> .hg/hgrc <<EOF > [ui] > ssh = "$PYTHON" "$TESTDIR/dummyssh" > EOF $ hg pull ssh://user@dummy/repo1 -r tip -B a pulling from ssh://user@dummy/repo1 no changes found $ disable_cap lookup $ hg pull ssh://user@dummy/repo1 -r tip -B a pulling from ssh://user@dummy/repo1 abort: other repository doesn't support revision lookup, so a rev cannot be specified.
