repair: move phases code after invalidation code

largefiles: remove empty directories upon update (issue3202)

revset: optimize roots and children

revset: optimize building large lists in formatrevspec The large or-expressions we used to build required a substantial amount of subset filtering in orset() which was inefficient. Instead we build a single string which we process in one go with a special internal predicate.

hg-ssh: use shlex for shell-like parsing of SSH_ORIGINAL_COMMAND The Mercurial ssh protocol is defined as if it was ssh-ing to a shell account on an ordinary ssh server, and where hg was available in $PATH and it executed the command "hg -R REPOPATH serve --stdio". The Mercurial ssh client can in most cases just pass REPOPATH to the shell, but if it contains unsafe characters the client will have to quote it so the shell will pass the right -R value to hg. Correct quoting of repopaths was introduced in d8fa35c28335 and tweaked in 86fc364ca5f8. hg-ssh doesn't create the command via a shell and used a simple parser instead. It worked fine for simple paths without any quoting, but if any kind of quoting was used it failed to parse the command like the shell would do it. This makes hg-ssh behave more like a normal shell with hg in the path would do.

hooks: prioritize run order of hooks As of Mercurial 1.3, hooks are sorted in the order they are read into Mercurial. There are many instances when someone may want the hooks sorted in a specific order; this patch allows prioritizing hooks, while maintaining the existing enumeration for hooks without a priority.

merge with stable

merge: report all files in _checkunknown When doing hg up, if there is a file conflict with untracked files, currently only the first such conflict is reported. With this patch, all of them are listed. With this patch error message is now reported as a: untracked file differs b: untracked file differs abort: untracked files in working directory conflict with files in requested revision instead of abort: untracked file in working directory differs from file in requested revision: 'a' This is a follow up to an old attempt to do this here: http://selenic.com/pipermail/mercurial-devel/2011-August/033625.html

discovery: fix prepush documentation The prepush documentation claim that when we refuse to push, the second element of the returng tuple is an "outgoing" integer. value should be 0 when no outgoing changeset and 1 otherwise. In pratice if there are no outgoing changeset, "outgoing" value is alway 1 and util.Abort is raised on other error. the stable branch also include this error so it wasn't introduced by a recent refactoring.

phases: simplify phase exchange and movement over pushkey The code now only exchange draft root and only care about movement related to public//draft boundary. There is multiple reason to simplify this code: * Secret are never discovered anymore * We decided to not support more the three existing phase Removing phase index from pushkey (if ever decided) will be made in another commit.
