updated to "264128213d29: c"
update: warn about other topological heads on bare update A concern around the user experience of Mercurial is user getting stuck on there own topological branch forever. For example, someone pulling another topological branch, missing that message in pull asking them to merge and getting stuck on there own local branch. The current way to "address" this concern was for bare 'hg update' to target the tipmost (also latest pulled) changesets and complain when the update was not linear. That way, failure to merge newly pulled changesets would result in some kind of failure. Yet the failure was quite obscure, not working in all cases (eg: commit right after pull) and the behavior was very impractical in the common case (eg: issue4673). To be able to change that behavior, we need to provide other ways to alert a user stucks on one of many topological head. We do so with an extra message after bare update: 1 other heads for branch "default" Bookmark get its own special version: 1 other divergent bookmarks for "foobar" There is significant room to improve the message itself, and we should augment it with hint about how to see theses other heads or handle the situation (see in-line comment). But having "a" message is already a significant improvement compared to the existing situation. Once we have it we can iterate on a better version of it. As having such message is an important step toward changing the default destination for update and other nicety, I would like to move forward quickly on getting such message. This was discussed during London - October 2015 Sprint.

strip: invalidate phase cache after stripping changeset (issue5235) When we remove a changeset from the changelog, the phase cache must be invalidated, otherwise it could refer to changesets that are no longer in the repo. To reproduce the failure, I created an extension querying the phase cache after the strip transaction is over. To do that, I stripped two commits with a bookmark on one of them to force another transaction (we open a transaction for moving bookmarks) after the strip transaction. Without the fix in this patch, the test leads to a stacktrace showing the issue: repair.strip(ui, repo, revs, backup) File "/Users/lcharignon/facebook-hg-rpms/hg-crew/mercurial/repair.py", line 205, in strip tr.close() File "/Users/lcharignon/facebook-hg-rpms/hg-crew/mercurial/transaction.py", line 44, in _active return func(self, *args, **kwds) File "/Users/lcharignon/facebook-hg-rpms/hg-crew/mercurial/transaction.py", line 490, in close self._postclosecallback[cat](self) File "$TESTTMP/crashstrip2.py", line 4, in test [repo.changelog.node(r) for r in repo.revs("not public()")] File "/Users/lcharignon/facebook-hg-rpms/hg-crew/mercurial/changelog.py", line 337, in node return super(changelog, self).node(rev) File "/Users/lcharignon/facebook-hg-rpms/hg-crew/mercurial/revlog.py", line 377, in node return self.index[rev][7] IndexError: revlog index out of range The situation was encountered in inhibit (evolve's repo) where we would crash following the volatile set invalidation submitted by Augie in cbc52a99d057d11790cf5011e877c6f698bf57bf. Before his patch the issue was masked as we were not accessing the phasecache after stripping a revision. This bug uncovered another but in histedit (see explanation in issue5235). I changed the histedit test accordingly to avoid fixing two things at once.
