status: add a flag to terse the output (issue4119) This adds an experimental flag -t/--terse which will terse the output. The terse flag will respect other flags which filters the output. The flag takes a string whose value can be a subsequence of "marduic" (the order does not matter here.) Ignored files are not considered while tersing unless -i flag is passed or 'i' is there is the terse flag value. The flag is experimental for testing as there may be cases which will produce strange results with the flag. We can set the terse on by default by simply passing 'u' to the cmdutil.tersestatus(). This patch also adds a test file with tests covering the new feature.

commitextras: check the format of the arguments and no internal key is used This patch adds check to make the arguments are passed as KEY=VALUE and no key which is used internally is passed. This patch also adds test for the extension.

commitextras: move fb extension to core which add extras to a commit This patch moves the Facebook extension to add extra fields to a commit to a in-core extension.

archive: add an experimental config to control the metadata file template Experimental because given the possible complexity, it may be worth figuring out how to load this from a file, similar to the style files for the log command, instead of trying to stuff it on the command line.

archive: use a templater to build the metadata file There are no visible changes here. I'm starting to wonder if adding the '+' to the 'node' line instead of a separate key line in 3047167733dc was the right thing to do. The '{node}' keyword never includes '+' elsewhere, and the way setup.py works, it would truncate it anyway. Additionally, the file is missing '{p2node}' when 'wdir()' merges are archived. I thought about adding an 'identify' line that would correspond to `hg id -n`. But the other nodes are the full 40 characters, and the output most useful for versioning is the short form. All of this cries out for customization via templating. (Although maybe having the short identify line by default is still a good idea.)

commandserver: do not handle EINTR for selector.select selectors2 library handles EINTR transparently so we don't need to handle select.error ourselves.

debugobsolete: also report the number of obsoleted changesets This seems useful to have the number of obsoleted changesets when calling debugobsolete.

transaction-summary: display the summary for all transactions Now that we records "all" changes happening in a transaction (in tr.changes) we will be able to provide better report on various changes (phases turned public, changeset obsoleted, branch merged or created, etc..) This is far too late in the cycle to play with this, but having this existing method called more widely will help extensions to play around with various options during the 4.4 cycle. Instead of calling registersummarycallback only for transactions we want, we always call it and use the transaction name to decide when to report (eg: we do not want `hg amend` to report new obsoleted changesets). Filtering on transaction name does not seems great, but seems good enough for the moment. We can change the API during the next cycle. The previous manual call during unbundling of the bundle2 "obsmarkers" part is no longer necessary and has been dropped.

test-strip: fix call to super class in crashstriprepo The 'self' argument is already taken care of by the 'super(...)' call. Instead we were passing the repository instance as the 'desc' value. This got discovered by breaking the next changeset.

share: share 'cachevfs' with the source clone (issue5108) Share extension now also share caches reads and writes. Not sharing caches results in costly caches recomputations which can takes up to minutes when using shares on large repositories. There are a couple of file in the '.hg/cache/' that depends of the current visibility. Visibility can be affected by the working copy location, something which is specific to each share. We ignores them for this series because they: * are the minority, * already have a good fallback to other precomputed caches, * are only affected when people use the experimental evolution feature.

cachevfs: add a devel warning for cache access though 'vfs' This will help third party extensions to migrate to the new 'cachevfs'.

cachevfs: migration the tags fnode cache to 'cachevfs' This will help sharing the cache between shares.
