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.

zeroconf: use port from server instead of picking port from config (issue3746) In order to get the port, wrap create server instead of hgweb_mod/hgwebdir_mod.

scmutil: don't try to match modes on filesystems without modes (issue3740)

hgwebdir: honor web.templates and web.static for static files (issue3734)

branchmap: enable caching for filtered version too The `_branchcache` attribute is turned into a dictionary. Key are filter name and value is a `branchcache` object. Unfiltered version is cached as `None` filter. The attribute is renamed to `_branchcaches` to avoid confusion with the previous one. Both old and new contents are dictionary even if their contents are different. I prefer possible extension code to crash right away instead of just messing the wrong dictionary. As all different caches work isolated to each other, this code keeps the previous behavior of using the unfiltered cache we nothing is filtered. This is a cheap way to have cache collaborate and nullify potential impact in the default case.

branchmap: report filtername when read fails Now that we can have multiple one, we need to know which filecache failed to be read from disk.

branchmap: use a different file name for filtered view of repo

clfilter: ensure unfiltered repo have a filtername attribute too That will allows to use `repo.filtername` for dispatch purpose.

branchmap: move the cache file name into a dedicated function Filtered view of the repo will want to write they file name in a different file.

branchmap: read and write key part related to filtered revision Now that we have a third part for the cache key we need to write and read it on disk. It is only written when there is filtered revision. This keep the format compatible with older version. Notes that, at this state, filtered repository does not use any disk caches yet.
