test-module-imports: use test-repo requirement

largefiles: don't rehash largefiles in updatelfiles if standin hash changed Standins are read before and after an update/merge, and all the standins that changes are handed to updatelfiles for getting their corresponding largefiles updated. updatelfiles would then hash the largefile and see if it already matched the new expected hash. If so, it would skip the update. If different, the largefile would be updated. It would happen very rarely that the largefile happened to match the new hash (and thus not the old one) and the hashing would thus be pointless ... and hashing is not cheap. Instead, when it is known that the standin hash changed (from an update), just update the standin unconditionally. If the largefile was "unsure" before the update, it was hashed at that point, so we know there is nothing to preserve. (Also, the hashing in updatelfiles was not used to preserve changes, but only to be lazy about updating the largefile, so nothing is lost by not doing this extra hashing.) There might be rare situations where we now will update largefiles that didn't have to be updated, but in all relevant cases (?) this will improve performance. Updates on a repo with some big largefiles has been seen to go from 9.19 s to 6.8 s - that is 26% less painful.

largefiles: show progress when checking standin hashes in outgoing changesets This checking can take a huge amount of time and we should give user a hint that something is going on.

unbundle: support bundle2 files This adds support for bundle2 files to the unbundle command.

pullbundle2: extract addchangegroup result combining into its own function This will also be used for 'hg unbundle'

histedit: add a test to show that issue4251 is fixed (issue4251) This will help us not regress this case in the future.

commands.debugbundle: bundle2 support This enables debugbundle to print supporting info for bundle2 files.

largefiles: cleanup overrideadd() This was a remnant of the code prior to overridding cmdutil.add().

largefiles: enable subrepo support for add The --large, --normal and --lfsize args couldn't be passed to a subrepo before, and files in the subrepos would be added silently (if -v wasn't specified) as normal files. As an added bonus, 'hg add --dry-run' no longer prints that largefiles would also be added as normal files as well.

add: pass options via keyword args The largefiles extensions needs to be able to pass --large, --normal and --lfsize to subrepos via cmdutil.add() and hgsubrepo.add(). Rather than add additional special purpose arguments, stop extracting the existing args from the **opts passed to commands.add() and just pass them along.

largefiles: don't pop largefile-specific arguments to the add command The arguments will need to stay present when making add work with subrepos.

share: replace the bookmarks.shared file with an entry on a new "shared" file cd79fb4d75fd introduced a way to share bookmarks. When a repository share that shares bookmarks was created, a .hg/bookmarks.shared file was created to mark the repository share as one that shares its bookmarks. We have plans to introduce other levels of sharing, including a "full share" mode. Rather than creating a new ".shared" file for each new thing that we may want to share It seems better to create a single "shared" file that will list what is shared for a given shared repository. This should make it much easier to get a list of everything that is shared by a given shared repository. The shared file contains a list of shared "items" (such as bookmarks). Each shared "item" is added as a new line in the file. For now the only possible entry in the file is "bookmarks".

docker: support Fedora 21

rpm: make Python 2.7.9 the default Python to include in rpms for EL 5 Use the new and more TLS support in Python 2.7.9.
