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. Differential Revision: https://phab.mercurial-scm.org/D2587

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

tests: prevent enormous output spew in test-lfs-largefiles.t This test currently fails on Python 3, but in a super-slow way. Adding this `head` invocation costs us nothing, but will prevent failures in this area from being super expensive. Differential Revision: https://phab.mercurial-scm.org/D2600

py3: fix formatting of path-auditing errors

py3: make os.curdir a bytes

py3: make os.pardir a bytes

py3: fix slicing of bytes in patch.iterhunks()

tests: fix various test-check-module-imports.t violations Somehow these are only caught when running the test under Python 3. Differential Revision: https://phab.mercurial-scm.org/D2580

pycompat: prevent encoding or decoding values if not required pycompat.py has functions strurl and bytesurl which decodes and encodes the url passed on Python 3 respectively. In some cases, strurl gets a url which is already str and bytesurl gets a url which is already bytes. Let's prevent encoding or decoding the values again if not required.

py3: silence the final IOError by closing stdout/err slightly early Fixes the following test failure: $ hg status >/dev/full abort: No space left on device Exception ignored in: <_io.TextIOWrapper name='<stdout>' mode='w' ... OSError: [Errno 28] No space left on device [120]

py3: conditionalize initialization of stdio flags Since Python 3 doesn't depend on the stdio of libc, there should be no need to set O_BINARY flag on Windows.

test-command-template: glob out detailed "invalid escape" message Python 3 also reports the position where an invalid escape found.

templater: byte-stringify dict/list values before passing to default format bytestr() is applied only when no custom format string like '%d' is specified.

templater: allow dynamically switching the default dict/list formatting '%s' doesn't work nicely on Python 3 because many Python types don't implement __bytes__().

py3: use util.forcevytestr to convert error to bytes Differential Revision: https://phab.mercurial-scm.org/D2585

util: report integer result from write() Python 2 sometimes returns None from write() calls. Python 3 doesn't. This will make test output inconsistent between Python 2 and 3. So let's paper over the differences by converting None to the length of the result string. Differential Revision: https://phab.mercurial-scm.org/D2584
