py3: add missing b prefixes in test-acl.t There's one failure left in the test, which looks like a real problem around executing hooks. I have not investigated further. # skip-blame as just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D5677

py3: buildbot found more passing tests, thanks to indygreg for most of them Differential Revision: https://phab.mercurial-scm.org/D5676

tests: drop a duplicate definition of a constant Differential Revision: https://phab.mercurial-scm.org/D5663

tests: support URL quoting on Python 3 We could use mercurial.urllibcompat, but meh. This makes things easier to read. The test still fails on Python 3 for some reason. But at least we no longer have an exception. Differential Revision: https://phab.mercurial-scm.org/D5669

tests: write directly to stdout to avoid b'' prefixes This enables the test to pass on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5668

tests: handle string escaping/encoding on Python 3 This code was failing on Python 3 for a few reasons: 1) sys.argv is str and str doesn't have a .decode() 2) the "string_escape" encoding was renamed to "unicode_escape" It is wonky casting to bytes to str to bytes. But this is test code, so meh. I don't believe we exercise any code paths in these tests where the arguments aren't ascii. Differential Revision: https://phab.mercurial-scm.org/D5667

convert: use raw strings for XML strings Due to the source transformer, we were passing bytes into the XML APIs. This results in not finding elements and doing compares against mismatched types. Use raw string literals so we use str everywhere. Differential Revision: https://phab.mercurial-scm.org/D5664
