exchange: directly 'getchangegroup' It is identical to 'getlocalchangegroup' with a shorter name.

commands: directly 'getchangegroup' It is identical to 'getlocalchangegroup' with a shorter name.

changegroup: deduplicate 'getlocalchangegroup' The two functions 'getlocalchangegroup' and 'getchangegroup' have been strictly identical for multiple years ('getchangegroup' had a deprecated docstring) We'll drop one of them (getlocalchangegroup, since it has the longest name). However, we needs to migrate all users of the dropped one to the new one before we can deprecate it. In the mean time we drop one of the duplicated definition and the outdated docstring.

py3: add test to show 'hg log -Tjson' works

py3: add test to show 'hg log -G' works

py3: rename test-check-py3-commands.t to test-py3-commands.t test-check-*.t is a set of tests which tests certain coding style checks. So this test was wrongly named, thanks to marmoute for pointing this out.

py3: use list of bytes rather than bytestring while extending bytes into lists Python 2: >>> ls = [] >>> ls.extend(b'abc') >>> ls ['a', 'b', 'c'] Python 3: >>> ls = [] >>> ls.extend(b'abc') >>> ls [97, 98, 99] So to make sure things work fine in Py3, this patch does: >>> ls = [] >>> ls.extend([b'a', b'b', b'c']) >>> ls [b'a', b'b', b'c'] After this `hg log -G` works!

py3: use pycompat.byteskwargs to converts kwargs to bytes baseformatter._item must contain both keys and values in bytes. So to make sure that, we convert the opts back to bytes.

py3: make adefaults keys str to be compatible with getattr getattr passes a str value of the attribute to be looked and keys in adefaults dict are bytes which resulted in AttributeError. This patch abuses r'' to make the keys str.

py3: abuse r'' to access keys in keyword arguments

py3: use pycompat.bytechr instead of chr

py3: use %d to format integers into bytestrings
