tests: handles bytes/str mismatch in test-commit-interface-curses.t This fixes various test failures on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5727

githelp: format with %d if an integer Python 3 doesn't allow us to format an int with %s like Python 2 did. So handle that. Differential Revision: https://phab.mercurial-scm.org/D5726

githelp: make argument parsing more compatible with Python 3 There were various mixing of str and bytes in here. This change fixes most of the failures in test-githelp.t. Differential Revision: https://phab.mercurial-scm.org/D5725

tests: add b'' prefixes to flagprocessorext.py Otherwise a part of test-flavprocessor.t fails due to not setting the proper key. Differential Revision: https://phab.mercurial-scm.org/D5724

tests: add b'' to config file name Without this, things die in the bowels of the config system due to mixing str and bytes. # skip-blame: just b'' prefix Differential Revision: https://phab.mercurial-scm.org/D5723

sslutil: ensure serverhostname is bytes when formatting It will likely be a str on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5722

sslutil: use raw strings for exception reason compare Otherwise we attempt to compare a bytes to a str on Python 3 and it always fails. Differential Revision: https://phab.mercurial-scm.org/D5721

keepalive: track ready state with a bool This code may have been written before Python had a bool type. Differential Revision: https://phab.mercurial-scm.org/D5719

keepalive: use collections.defaultdict for host map Cleaning up the code as part of debugging Python 3 issues. Differential Revision: https://phab.mercurial-scm.org/D5718

statichttprepo: use str to appease Python 3 The URL fed into urllib and HTTP headers need to be str on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5716
