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: add some b'' to make test-lock-badness.t happy

py3: fix formatting of lock error message

py3: fix some unicode madness in global exception catcher

py3: pass a system-string filename to sub-classes of IOError

py3: fix some membership tests on linkrev adjustment

py3: make test-basic.t pass on Python 3

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

util: log readinto() I/O Differential Revision: https://phab.mercurial-scm.org/D2583

util: teach escapedata() about bytearray re.map doesn't seem to know about bytearray (at least in Python 2). Cast bytearray to a bytes to work around this inconvenience. Differential Revision: https://phab.mercurial-scm.org/D2582

sshpeer: don't read(0) read(0) is essentially a no-op. Let's avoid the function call, overhead, and extra test output by not performing it. Differential Revision: https://phab.mercurial-scm.org/D2581

py3: unblock C extensions on Python 3 Please make sure to build C extensions before running tests with -l: $ make local PYTHON=python3

py3: make test-ancestors.py pass on Python 3 with C extensions # skip-blame just some b prefixes

py3: do not pass a memoryview to bdiff.bdiff() This doesn't look nice, but I don't know how to make a zero-copy slice of bytes which is compatible with the buffer protocol.

py3: do not pass a list of iterators to computephasesmapsets()
