tests: fix inline extension bytes in test-ssh-proto-unbundle.t # skip-blame just b prefixes Differential Revision: https://phab.mercurial-scm.org/D2610

hghave: fix up clang-libfuzzer regex to be bytes Fixes this check on Python 3. # skip-blame just a b prefix Differential Revision: https://phab.mercurial-scm.org/D2607

py3: accept both unicode and byte strings as filename carried by IOError Follows up 77f98867538f. We could assume there's no bytes filename in our codebase, but it's probably better to not raise UnicodeError because of a unicode filename.

py3: back out c77c925987d7 to store bytes filename in IOError Appears that this is how Python 3 works.

largefiles: headers and values need to be sysstrs, add r prefixes # skip-blame just some r prefixes Differential Revision: https://phab.mercurial-scm.org/D2606

cext: accept arguments as Py_buffer The s*/y* value formatters receive a Py_buffer instead of a char *. This value format is more flexible in the types that it allows. We change bdiff() to accept any object that conforms to the buffer protocol. We validate the buffers are contiguous and have a single dimension. This allows memoryview instances to be handled by the function, so we revert a recent change to cast arguments to bytes before calling this function.

cext: refactor cleanup code in bdiff() A future commit will need to introduce additional cleanup code. We refactor the cleanup code to check NULL before calling free(). We also initialize these variables as NULL. We set the out of memory exception explicitly, so we can just return result. Differential Revision: https://phab.mercurial-scm.org/D2586

py3: use pycompat.bytestr() to convert error messages to bytes Differential Revision: https://phab.mercurial-scm.org/D2535

url: more bytes/unicodes fussing in url.py around auth handling Once again, these methods are a little annoying to handle because they can get unicodes or bytes depending on who's calling. I think we can probably clean this up a TON once we can run something like pytype and do typechecking of our Python, but until then this is going to be the easy way out. This fixes test-http-bundle1.t. Differential Revision: https://phab.mercurial-scm.org/D2599

httpconnection: convert url to bytes in readauthforuri This method is sometimes called by the stdlib, so we just need to accept both bytes and unicodes here. Awesome. Differential Revision: https://phab.mercurial-scm.org/D2598
