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.

cachevfs: migrate tagscache to 'cachevfs' This will help sharing the cache between shares.

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

cachevfs: use the new vfs in when computing branchmap cache This will help sharing the cache between shares.

cachevfs: add a vfs dedicated to cache Most of the cache content lives in '.hg/cache/'. Moreover they are computed exclusively from data in the '.hg/store' directory. This creates issues with the share extension as the '.hg/store' directory is shared but the '.hg/cache' is not. On large repositories, this makes this prevent some usage of the share extension inefficient as some caches can take minutes to be recomputed. To improve the situation, we introduce a new 'cachevfs' that will be dedicated to cache reading and writing. In the next patches of this series, we'll migrate the 4 existing caches to it and update the share extension.

vfsward: register 'write with no lock' warnings as 'check-locks' config Update 'write with no lock' warnings in order to be better controlled by the config. We reuse the option used for lock order for these other lock related message. The message can now be disabled using 'devel.check-locks = no' (in addition to the usual 'devel.all-warnings = no').

demandimport: prefer loaded module over package attribute (issue5617) In general, the attribute of the same name is overwritten by executing an import statement. import a.b print(a.b.c) # 'c' of a/b/__init__.py from a.b.c import d print(a.b.c) # a/b/c.py However, this appears not true for the scenario described in the test case, and surprisingly, "from a.b.c import d" works even if "a.b.c" is not a module. This patch works around the problem by taking the right module from sys.modules if available.

demandimport: drop Py3 workarounds from Py2 implementation

demandimport: drop hack for old Pythons which had no level argument _import() was added by 868282fa29d8, but it is identical to _origimport() now.

tests: drop "absimport" conditionals which should be always true

color: drop the now useless color extension all the extension features are provided by core since 4.2.

extensions: expand the builtins extensions declaration This will future updates of the set cleaner and more readable.

debugextensions: drop the color from the test We are about to remove the extension so we remove trace of it in this specific test to prevent it to be confused.

configitems: register the 'bugzilla.notify' config

configitems: register the 'ui.mergemarkertemplate' config

configitems: register the 'ui.color' config

color: drop the _enabledbydefault module variable Since color is on by default, cleanup the now useless variable in both core and color extension.

configitems: register the 'ui.forcecwd' config

configitems: register the 'ui.fallbackencoding' config

bookmark: deprecate direct del of a bookmark value We want all bookmark deletion to go through 'applychanges', so lets deprecate legacy ways of doing bookmark deletion.

bookmark: deprecate direct set of a bookmark value We want all bookmark update to go through 'applychanges', so lets deprecate legacy ways of doing bookmark update.

bookmark: track bookmark changes at the transaction level The transaction has now a 'bookmarks' dictionary in tr.changes. The structure of the dictionary is {BOOKMARK_NAME: (OLD_NODE, NEW_NODE)}. If a bookmark is deleted NEW_NODE will be None. If a bookmark is created OLD_NODE will be None. If the bookmark is updated multiple time, the initial value is preserved.

bookmark: deprecate 'recordchange' in favor of 'applychanges' Now that we have migrated all in-core caller of 'recordchange' to 'applychanges', deprecate 'recordchange' so external callers will move to the new unified method.

bookmark: drop deletedivergent It has no caller anymore.

bookmark: use 'divergent2delete' in checkconflict checkconflict used to also do some bookmark deletion in case of divergence. It is a bit suspicious given the function name, but it's not the goal of this series. In order to unify bookmarks changing, checkconflict now return the list of divergent bookmarks to clean up and the callers must clean them by calling applyphases.

bookmark: use 'divergent2delete' when updating a bookmark

bookmark: use 'divergent2delete' in 'scmutil.cleanupnode'
