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.

find_deepest is used to find the "best" ancestors given a list. In the main
loop it keeps an invariant called 'ninteresting' which is supposed to contain
the number of non-zero entries in the 'interesting' array. This invariant is
incorrectly maintained, however, which leads the the algorithm returning an
empty result for certain graphs. This has been fixed.
Also, the 'interesting' array is supposed to fit 2^ancestors values, but is
incorrectly allocated to twice that size. This has been fixed as well.
The tests in test-ancestor.py compare the Python and C versions of the code,
and report the error correctly, since the Python version works correct. Even
so, I have added an additional test against the expected result, in the event
that both algorithms have an identical error in the future.
This fixes issue5623.
This allows us to write doctests depending on a ui object, but not on global
configs.
ui.load() is a class method so we can do wsgiui.load(). All ui() calls but
for doctests are replaced with ui.load(). Some of them could be changed to
not load configs later.
This allows multiple efficient missing ancestor queries against the same set of
bases. In upcoming patches we'll also define ways to grow the set of bases.
The fact that the test output hasn't changed establishes this patch's
correctness.
I was wondering if revisions in the initial set that are still ancestors of other
elements in the initial set were yielded by `changelog.ancestors`. I now have my
answer (they do) and Mercurial has a new test.
ninteresting indicates the number of non-zero elements in the interesting
array, not the number of elements in the final list. Since elements in
interesting can stand for more than one gca, limiting the number of results to
ninteresting is an error.
Tests for issue3984 are included.
This also makes the perfancestorset command use lazy membership testing. In a
linear repository with over 400,000 commits, without this patch, hg
perfancestorset takes 0.80 seconds no matter how far behind we're looking.
With this patch, hg perfancestorset -- X takes:
Rev X Time
-1 0.00s
-4000 0.01s
-20000 0.04s
-80000 0.17s
-200000 0.43s
-300000 0.69s
0 0.88s
Thus, for revisions close to tip, we're up to several orders of magnitude
faster. At 0 we're around 10% slower.
