branchmap: disable fallback to unfiltered branchcache Disables this simple optimisation to allow coming more powerfull approach: cache collaboration. Our goal is to have branchcache collaborate. This means that unfiltered branchcache will fallback to some filtered branchcache if invalid. We can't have the filtered branchcache to use the unfiltered one. That would loop.

localrepo: filter unknown nodes from the phasecache on destroyed When commit is followed by strip (qrefresh), phasecache contains nodes that were removed from the changelog. Since phasecache is filecached with .hg/store/phaseroots which doesn't change as a result of stripping, we have to filter it manually. If we don't write it immediately, the next time it is read from disk the nodes will be filtered again. That's what happened before, but there's no reason not to write it immediately. The change in test-keyword.t is caused by the above.

phases: make _filterunknown a member function of phasecache We'd like the ability to call filterunknown on an existing phasecache instance after nodes are destroyed.

localrepo: drop `_cacheabletip` method It iss dead code now.

branchmap: drop `_cacheabletip` usage in `updatecache` Nobody overwrite the `_cacheabletip` any more. We always update the cache for the whole repo and write it to disk (or at list try to). The `updatecache` code is simplied to remove the double phase logic associated with _cacheabletip.

mq: drop `_cacheabletip` usage Strip have dedicated work around to solve the same problem, strip is even a fraction faster without that thanks to simpler update process of the branchcache.

bundlerepo: drop use of `_cacheabletip` Now that bundlerepo use a read only VFS, we do not worry about what part of the branchmap is written back to disk. Nothing is written at all.

bundlerepo: enforce reading from core repo only We do not want anything computed with the bundle overlay to be written back in the repo. Such write will likely contains invalid data. The short terms goal of this change is to drop use of `_cacheabletip` in bundle repo.

branchmap: ignore Abort error while writing cache Read only vfs can now raise Abort exception. Note that encoding.local are also a possible raiser.

vfs: add a read only vfs This read only wrapper is intended to be used bundle repo. See follow up commit for details.

branchmap: read return None in case of failure This makes a clear distinction between having read a valid cache on disk or not. This will help caches of various filtering level to collaborate.

clfilter: fallback to unfiltered version when linkrev point to filtered history On `filectx`, linkrev may point to any revision in the repository. When the repository is filtered this may lead to `filectx` trying to build `changectx` for filtered revision. In such case we fallback to creating `changectx` on the unfiltered version of the reposition. This fallback should not be an issue because `changectx` from `filectx` are not used in complex operation that care about filtering. It is complicated to work around the issue in a clearer way as code raising such `filectx` rarely have access to the repository directly. Linkrevs create a lot of issue with filtering. It is stored in revlog entry at creation time and never changed. Nothing prevent the changeset revision pointed to become filtered. Several bogus behavior emerge from such situation. Those bugs are complex to solve and not part of the current effort to install filtering. This changeset is simple hack that prevent plain crash in favor on minor misbehavior without visible effect. This "hack" is longly documented in to code itself to help people that would look at it in the future.

phases: prepare phase command for filtering The phase command have some logic to report change made. We ensure this logic run unfiltered. With --force the command can change phase of a changeset for public to draft. Such change can lead to obsolescence marker to apply again and the changeset to be "hidden". If we do not run the logic unfiltered it could failed to fetch the phase of a newly filtered changeset.

phases: avoid changectx creation while checking command result This minor changesets saves the creation of a `changectx` ctx object only used to fetch the revision number.

test: use obsolescence marker to test hidden Instead of using a custom dedicated extension.

hgweb, paper: add (Atom) subscribe links to the repository index This is similar to the subscribe links that already exist in other templates. Rather than the usual RSS and Atom links a single feed icon linking to the atom-log is shown.

hgweb: add (Atom) subscribe link to the main paper template pages The subscribe link is found at the bottom of the navigation sidebar. This uses a free icon from http://feedicons.com.

test-command-template.t: fix test so it all year This test started failing for me after midnight UTC on December 31st. Fixed it by specifying a date 7 years in the future more precisely (rather than just adding 8 to the year and specifying January 1st), which allows the test to pass both now and on 2012-12-01 at the same time.

amend: prevent loss of bookmark on failed amend The active bookmark were moved to the temporary commit. When the transaction were rollbacked, the bookmark were lost. We now temporarly disable the bookmark to prevent this effect.

amend: invalidate dirstate in case of failure (issue3670) The temporary commit created by amend update the dirstate. If the final commit fails, we need to invalidate the change made to the dirstate, otherwise the release of the wlock will write the dirstate created after the rollbacked temporary commit. This dirstate writing logic should probably be handled in the same object than the transaction one. However such change are too big for stable.
