dispatch: check shell alias again after loading extensions (issue4355) Before this patch, the shell alias causes failure when it takes its specific (= unknown for "hg") options in the command line, because "_parse()" can't accept them. This is the regression introduced by 03d345da0579. It fixed the issue that ambiguity between shell aliases and commands defined by extensions was ignored. But it also caused that ambiguous shell alias is handled in "_parse()" even if it takes specific options in the command line. To avoid such failure, this patch checks shell alias again after loading extensions. All aliases and commands (including ones defined by extensions) are completely defined before the 2nd (= newly added in this patch) "_checkshellalias()" invocation, and "cmdutil.findcmd(strict=False)" can detect ambiguity between them correctly. For efficiency, this patch does: - omit the 2nd "_checkshellalias()" invocation if "[ui] strict= True" it causes "cmdutil.findcmd(strict=True)", of which result should be equal to one of the 1st invocation before adding aliases - avoid removing the 1st "_checkshellalias()" invocation it causes "cmdutil.findcmd(strict=True)" invocation preventing shell alias execution from loading extensions uselessly

dispatch: make "_checkshellalias" reusable regardless of adding aliases To reduce changes in the subsequent patch fixing issue4355, this patch makes "_checkshellalias" reusable regardless of adding aliases. In this patch, alias definitions are added and restored, only when "precheck=True".

build: don't clean __version__.py on 'make clean' in release tarballs When running 'make clean' in an extracted release tarball, file mercurial/__version__.py is removed, causing a subsequent install to indicate 'version unknown'. This problem was reported in the past [1] and a patch proposed in that mail, but was never properly sent nor applied. [1] http://selenic.com/pipermail/mercurial/2010-December/036249.html

revert: drop now useless conditional in the backup check Now that we removed the (hopeless) attempt to backup file we knew to be missing in the target changeset, we can stop checking if the file exists in the target changeset.

revert: no backup for `dsadded` set There is only one case where a backup is required in the `dsadded` set, and the current backup mechanism fails to handle it. So we stop trying to do backups at all for now. This will help us to simplify the backup code and finally fix this backup issue.

revert: add more padding in the dispatch list We are going to add more sets and some of them will have longer names. We add padding in a standalone patch for readbility purposes.

revert: add documentation in the dispatch table More sets are coming so documenting the existing ones will help.

revert: add a way for external extensions to prefetch file data This allow extensions that mess with the storage layer (remotefilelog, largefile) to prefetch any data that will be accessed during the revert operation. We are currently fetching more data than theoretically required because the backup code is a bit stupid. Future patches will improve that.

histedit: abort gracefully on --continue/--abort with no state Previously we'd print an ugly message saying that the histedit-state file doesn't exist in the repo.

Added tag 3.1.1 for changeset 5dc91146f353

bookmarks: allow pushkey if new equals current Previously a bookmark pushkey would be rejected if the specified 'old' value didn't match the servers 'current' value. This change allows this situation, as long as the 'current' server value equals the 'new' pushkey value already. We are trying to write a hook that forces a server bookmark to move forward, using a changegroup hook. If the user also pushed the bookmark, they would get an error, since they computed their pushkey (old,new) pair before the server moved the bookmark. Long term, bundle2 will let us do this more smartly, but this change seems reasonable for now.

tests: improve test coverage of branch command and existing branches

localrepo: make it possible to pass multiple path elements to join and wjoin This makes join and wjoin behave in the same way as os.path.join. That is, it makes it possible to pass more than one path element to them. Note that the first path element is still required, as it was before this patch, and as is the case for os.path.join.

run-tests: make --interactive work with --view

convert: don't use multi-argument set.update Mumble mumble 2.4 mumble.

error: use docstrings, not bare strings, for error classes

osx: create dmg with installer instead of zip OS X would offer to expand the zip so the (multi file) installer inside it could be run ... but that would leave the expanded zip folder around. Instead, use a .dmg file that automatically will be mounted - that seems more common on OS X. Still, there is two levels of levels of clicking before actually launching the installer. Having a single file installer would be better ... but seems to be hard. A more feasible improvement would be some fancy layout inside the .dmg .

branchmap: pre-filter topological heads before ancestors based filtering We know that topological heads will not be ancestors of anything, so we filter them out to potentially reduce the range of the ancestors computation. On a strongly headed repo this gives humble speedup: from 0.1984 to 0.1629

branchmap: issue a single call to `ancestors` for all heads There is no reason to make multiple calls. This provides a massive speedup for repo with a lot of heads. On a strongly headed repo this gives humble speedup in simple case: from 8.1097 to 5.1051 And massive speedup in other case: from 7.8787 to 0.1984

test-ancestor: add a test for `ancestor` with ancestry within the initset I was wondering if revisions in the initial set that are still ancestors of other elements in the initial set were yielded by `changelog.ancestors`. I now have my answer (they do) and Mercurial has a new test.

bundle2: pull obsmarkers relevant to the pulled set through bundle2 We use the new `obsheads` argument to retrieve them in a bundle2 part at the same time as the changegroup.
