test-histedit-commute: call helper script with sh Buildbot pointed out that this test wasn't passing on Linux+vfat because there's no chmod for shell scripts.

test-tools: fix portability issues

progress: add a lock to prepare for introducing a thread

progress: move update check into helper method

progress: move current topic to member variable

progress: add try/finally to make the diffs for the next commit more readable No change in behavior.

transaction: include backup file in the "undo" transaction Once the transaction is closed, we now write transaction related data for possible future undo. For now, we only do it for full file "backup" because their were not handle at all in that case. In the future, we could move all the current logic to set undo up (that currently exists in localrepository) inside transaction itself, but it is not strictly requires to solve the current situation.

transaction: pass the name of the "undo" journal to the transaction It is time for the transaction to be responsible for setting up the undo data. It is necessary to move this logic into the transaction because many more files are handled now, and the transaction is the object tracking them all. The value can be set to None if no undo should be set.

rollback: have an empty entry for the vfsmap in rollback This empty string key is used for the store. This will be needed to properly rollback backup in a future changesets.

transaction: clarify the name of 'journal' argument for transaction The argument is a string containing the journal name (used as prefix for all other transaction file). This is not the transaction file itself. So we clarify this.

transaction: use 'util.copyfile' for creating backup Using 'copyfile' (single file) instead of 'copyfiles' (tree) will ensures destination file will be overwritten. This will prevent some abort if backup file are left in place for random reason. It also seems more correct.

copyfile: allow optional hardlinking Some code paths use 'copyfiles' (full tree) for a single file to take advantage of the best-effort-hard-linking parameter. We add similar parameter and logic to 'copyfile' (single file) for this purpose. The single file version have the advantage to overwrite the destination file if it exists.

repair: add experimental option to write bundle2 files This adds an experimental option 'strip-bundle2-version' which causes backup bundles to use bundle2 formatting. Especially for generaldelta repositories, this should provide significant performance gains for any operation that needs to write a backup.

changegroup.getsubset: support multiple versions Allow a version parameter to specify which version of the packer should be used

changegroup.writebundle: HG2Y support This diff adds support to writebundle to generate a bundle2 wrapper; upcoming diffs will add an option to write a v2 changegroup part instead of v1 in these bundles.

changegroup.writebundle: provide ui The next diff will add support for writing bundle2 files to writebundle, but the bundle2 generator wants access to a ui object. This changes the signature and callsites to pass one in.

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.
