Summary: Turned on the auto formatter. Ran `arc lint --apply-patches --take BLACK **/*.py`. Then run `arc lint` again so some other autofixers like spellchecker etc. looked at the code base. Manually accept the changes whenever they make sense, or use a workaround (ex. changing "dict()" to "dict constructor") where autofix is false positive. Disabled linters on files that are hard (i18n/polib.py) to fix, or less interesting to fix (hgsubversion tests), or cannot be fixed without breaking OSS build (FBPYTHON4). Conflicted linters (test-check-module-imports.t, part of test-check-code.t, test-check-pyflakes.t) are removed or disabled. Duplicated linters (test-check-pyflakes.t, test-check-pylint.t) are removed. An issue of the auto-formatter is lines are no longer guarnateed to be <= 80 chars. But that seems less important comparing with the benefit auto-formatter provides. As we're here, also remove test-check-py3-compat.t, as it is currently broken if `PYTHON3=/bin/python3` is set.

# Helper script used for generating history and working copy files and content.
|
|
# The file's name corresponds to its history. The number of changesets can
|
|
# be specified on the command line. With 2 changesets, files with names like
|
|
# content1_content2_content1-untracked are generated. The first two filename
|
|
# segments describe the contents in the two changesets. The third segment
|
|
# ("content1-untracked") describes the state in the working copy, i.e.
|
|
# the file has content "content1" and is untracked (since it was previously
|
|
# tracked, it has been forgotten).
|
|
#
|
|
# This script generates the filenames and their content, but it's up to the
|
|
# caller to tell hg about the state.
|
|
#
|
|
# There are two subcommands:
|
|
# filelist <numchangesets>
|
|
# state <numchangesets> (<changeset>|wc)
|
|
#
|
|
# Typical usage:
|
|
#
|
|
# $ python $TESTDIR/generate-working-copy-states.py state 2 1
|
|
# $ hg addremove --similarity 0
|
|
# $ hg commit -m 'first'
|
|
#
|
|
# $ python $TESTDIR/generate-working-copy-states.py state 2 1
|
|
# $ hg addremove --similarity 0
|
|
# $ hg commit -m 'second'
|
|
#
|
|
# $ python $TESTDIR/generate-working-copy-states.py state 2 wc
|
|
# $ hg addremove --similarity 0
|
|
# $ hg forget *_*_*-untracked
|
|
# $ rm *_*_missing-*
