formatting: byteify all mercurial/ and hgext/ string literals Done with python3.7 contrib/byteify-strings.py -i $(hg files 'set:mercurial/**.py - mercurial/thirdparty/** + hgext/**.py - hgext/fsmonitor/pywatchman/** - mercurial/__init__.py') black -l 80 -t py33 -S $(hg files 'set:**.py - mercurial/thirdparty/** - "contrib/python-zstandard/**" - hgext/fsmonitor/pywatchman/**') # skip-blame mass-reformatting only Differential Revision: https://phab.mercurial-scm.org/D6972

formatting: blacken the codebase This is using my patch to black (https://github.com/psf/black/pull/826) so we don't un-wrap collection literals. Done with: hg files 'set:**.py - mercurial/thirdparty/** - "contrib/python-zstandard/**"' | xargs black -S # skip-blame mass-reformatting only # no-check-commit reformats foo_bar functions Differential Revision: https://phab.mercurial-scm.org/D6971

style: run a patched black on a subset of mercurial This applied black to the 20 smallest files in mercurial/: ls -S1 mercurial/*.py | tail -n20 | xargs black --skip-string-normalization Note that a few files failed to format, presumably due to a bug in my patch. The intent is to be able to compare results to D5064 with https://github.com/python/black/pull/826 applied to black. I skipped string normalization on this patch for clarity - in reality I think we'd want one pass without string normalization, followed by another to normalize strings (which is basically replacing ' with " globally.) # skip-blame mass-reformatting only Differential Revision: https://phab.mercurial-scm.org/D6342

tests: conditionalize output for Python 3 It appears that the random.randint() behavior is different between Python 2 and Python 3. So make the test conditional on that. This makes the test pass on Python 3.7 (and presumably other Python 3 versions). Differential Revision: https://phab.mercurial-scm.org/D6964

hg: remove HGUNICODEPEDANTRY and RTUNICODEPEDANTRY This was added in 73e4a02e6d23 and 89822d7a9d5f as a preliminary way to better support Python 3. With the Python 3 port nearly done and better procedures in place, we shouldn't need it. Differential Revision: https://phab.mercurial-scm.org/D6991

convert: use pycompat.fsencode() This avoids a `TypeError: Can't mix strings and bytes in path components`. Differential Revision: https://phab.mercurial-scm.org/D6965

tests: make tarball output conditional on Python version Python 3.8 changed the default tar file archive format: https://docs.python.org/3.8/whatsnew/3.8.html#tarfile. This commit teaches our tests about the new behavior. Differential Revision: https://phab.mercurial-scm.org/D6986
