revset: fix outgoing argument handling

debugbuilddag: escape backslash properly in help string

url.py: removed 'file' inheritance in the httpsendfile class Since py3k doesn't have a "file" builtin and, consequently, doesn't support inheriting from it, this patch refactors the httpsendfile class to wrap the objects returned by the builtin "open" function while adding the necessary methods (__len__ for constructing the Content-Length header and read, write, close and seek for the file-like interface).

fix undefined variables, spotted by pylint

py3kcompat: added fake ord implementation for py3k In py3k, a bytes object __getitem__ will return an int instead of a one-character bytes object. This has negative consequences when we want to ord(), like in the following example: >>> b'foo'[0] 102 >>> ord(b'foo'[0]) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: ord() expected string of length 1, but int found This patch overrides the default ord() implementation to just return an int that's what is passed as an argument for ord(). Making the above call succeed: >>> ord(b'foo'[0]) 102

commit: explicitly document the existence of "last-message.txt"
