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