workingctx: unlink paths while holding the wlock

wireproto: do not hash when heads == ['force'] Changeset 88f0e41d8802 introduced the unbundlehash capability and unconditionally hashed the heads on the client side. By mistake, the heads were also cased in the heads == ['force'] case.

patch: remove EOL support from linereader class This was only used when reading patched files which is now done by backends.

subrepo: handle local added subrepo case correctly

graphlog: remove unused arg from _wrapcmd

extensions: raise when trying to find an extension that failed to load extensions that depend on other extensions (such as record) use this pattern to check if the dependant extension is available: try: mq = extensions.find('mq') except KeyError: return but since if an error occurs while loading an extension it leaves its entry in the _extensions map as None, we want to raise in that situation too. (rather than adding another check if the return value is None)

remove: clarify help text about added files never being deleted from disk

pure: provide more correct implementation of posixfile for Windows requires ctypes Why is posixfile a class? Because the implementation needs to use the Python library call os.fdopen [1], which sets the 'name' attribute on the Python file object it creates to the mostly meaningless string '<fdopen>', since file descriptors don't have a name. But users of posixfile depend on the name attribute [2] being set to a proper value, like Python's built-in 'open' function sets it on file objects. Python file's name attribute is read-only, so we can't just assign to it after the file object has alrady been created. To solve this problem, we save the name of the file on a wrapper object, and delegate the file function calls to the wrapped (private) file object using __getattr__.

bundlerepo: make getremotechanges support filtering of incoming Extensions can hook discovery.findcommonincoming to filter out unwanted remote changesets. This patch makes getremotechanges respect the changed remote heads returned by such extensions.

tests: add tests for discovery/pull without cgsubset
