phase: gather remote phase information in a summary object We keep useful phase information around. The data will be reused with detecting push-race in later changesets.

phase: simplify the check for issue3781 shortcut in discovery We'll rework the code around this check. Limiting the entanglement will help with later changesets

exchange: fix issue3781 reference in the comment This comment is about: issue3781: Courtesy Phases synchronisation to publishing server prevent subrepo push Not about: issue3871: Slow hg log when template contains {file_adds}, {file_mods} and {file_dels}

phase: filter out non-draft item in "draft root" The on-disk file can contain draft root that are descendants of secret root. The resulting phase computation is correct, but the phases root content is not. I will send another series to introduce code that remove some of the cases where this can happens, but we first need to damage control the existing case. After this changeset, we can no longer advertise secret changeset as draft root.

subrepo: share instead of clone if the parent repo is shared (issue5675) (BC) Previously, only the top level repo was shared, and then any subrepos were cloned on demand. This is problematic because commits to the parent repo would write an updated .hgsubstate to the share source, but the corresponding subrepo commit would be stuck in the local subrepo. That would prevent an update in the source repo. We already go to great lengths to avoid having inconsistent repos (e.g., `hg push -r rev` will push _everything_ in a subrepo, even if it isn't referenced in one of the parent's outgoing commits). Therefore, this seems like a bug fix, and there's no option to get the old behavior. I can't imagine the previous behavior was useful to anybody. There shouldn't be an issue with svn, since it is centralized. Maybe --git-dir can be used for git subrepos, but I'll leave that to someone more familiar with git. An integer was previously being implicitly returned from commands.share(), which caused dispatch() to start crashing when changing over to returning the shared repo. All error paths appear to raise, so this can be hardcoded to success. The clone command checks for 'is None' in a similar pattern, but since hg.clone() always returns a tuple, that seems wrong? .. fix:: Issue 5675 Creating a share of a repository with a Mercurial subrepository will now share the subrepository. and .. bc:: Mercurial subrepositories are now shared instead of cloned when the parent repository is shared. This prevents dangling subrepository references in the share source. Previously shared repositories with cloned subrepositories will continue to function unchanged.
