hgweb: document the revnavgen function

hgweb: no do not use listinsert(0, ...) This is not efficient. We now append element and either reverse the list or iterate in reverse order.

localrepo: drop unnecessary check on wlock unlock Calling out to dirstate one line before guarantees that it'll be in the filecache.

dirstate: refresh _branch cache entry after writing it

filecache: create an entry in _filecache when __set__ is called for a missing one Preserve the invariant that if P is a filecached property on X then P in X.__dict__ => P in X._filecache. Previously, it was possible for a filecached property to become out of sync with the filesystem if it was set before getting it first, since the initial filecacheentry was created in __get__. Old behaviour: repo.prop = x repo.invalidate() # prop has no entry in _filecache, it's not removed # from __dict__ repo.prop # returns x like before without checking with the # filesystem New: repo.prop = x # an empty entry is created in _filecache repo.invalidate() # prop is removed from __dict__ repo.prop # recreates prop

filecache: allow filecacheentry to be created without stating in __init__ Will be used for properties that are set without getting them first.

rollback: don't clear the filecache This was an old workaround to force the filecache to reload everything. Now that the syncing issue is fixed, we no longer need it.
