Add revlog.strip to truncate away revisions.
This updates the revlog data structures for index and nodemap in place
so the .d and .i files don't need to be reread after stripping away a revision.
def demandload(scope, modules):
class d:
def __getattr__(self, name):
mod = self.__dict__["mod"]
scope = self.__dict__["scope"]
scope[mod] = __import__(mod, scope, scope, [])
return getattr(scope[mod], name)
for m in modules.split():
dl = d()
dl.mod = m
dl.scope = scope
scope[m] = dl
