codemod: join the auto-formatter party
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.

flake8: enable F821 check
Summary:
This check is useful and detects real errors (ex. fbconduit). Unfortunately
`arc lint` will run it with both py2 and py3 so a lot of py2 builtins will
still be warned.
I didn't find a clean way to disable py3 check. So this diff tries to fix them.
For `xrange`, the change was done by a script:
```
import sys
import redbaron
headertypes = {'comment', 'endl', 'from_import', 'import', 'string',
'assignment', 'atomtrailers'}
xrangefix = '''try:
xrange(0)
except NameError:
xrange = range
'''
def isxrange(x):
try:
return x[0].value == 'xrange'
except Exception:
return False
def main(argv):
for i, path in enumerate(argv):
print('(%d/%d) scanning %s' % (i + 1, len(argv), path))
content = open(path).read()
try:
red = redbaron.RedBaron(content)
except Exception:
print(' warning: failed to parse')
continue
hasxrange = red.find('atomtrailersnode', value=isxrange)
hasxrangefix = 'xrange = range' in content
if hasxrangefix or not hasxrange:
print(' no need to change')
continue
# find a place to insert the compatibility statement
changed = False
for node in red:
if node.type in headertypes:
continue
# node.insert_before is an easier API, but it has bugs changing
# other "finally" and "except" positions. So do the insert
# manually.
# # node.insert_before(xrangefix)
line = node.absolute_bounding_box.top_left.line - 1
lines = content.splitlines(1)
content = ''.join(lines[:line]) + xrangefix + ''.join(lines[line:])
changed = True
break
if changed:
# "content" is faster than "red.dumps()"
open(path, 'w').write(content)
print(' updated')
if __name__ == "__main__":
sys.exit(main(sys.argv[1:]))
```
For other py2 builtins that do not have a py3 equivalent, some `# noqa`
were added as a workaround for now.

codemod: join the auto-formatter party
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

codemod: join the auto-formatter party
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.

other processes having access to the pending data before it is
finalized.
The way it works today, the localrepo class loads the changelog
like normal. Then, if it detects a pending transaction, it asks
the changelog class to load a pending changelog. The changelog
class looks for a 00changelog.i.a file. If it exists, it is
loaded and internal data structures on the new revlog class are
copied to the original instance.
The existing mechanism is inefficient because it loads 2 revlog
files. The index, node map, and chunk cache for 00changelog.i
are thrown away and replaced by those for 00changelog.i.a.
The existing mechanism is also brittle because it is a layering
violation to access the data structures being accessed. For example,
the code copies the "chunk cache" because for inline revlogs
this cache contains the raw revision chunks and allows the original
changelog/revlog instance to access revision data for these pending
revisions. This whole behavior of course relies on the revlog
constructor reading the entirety of an inline revlog into memory
and caching it. That's why it is brittle. (I discovered all this
as part of modifying behavior of the chunk cache.)
This patch streamlines the loading of a pending 00changelog.i.a
revlog by doing it directly in the changelog constructor if told
to do so. When this code path is active, we no longer load the
00changelog.i file at all.
The only negative outcome I see from this change is if loading
00changelog.i was somehow facilitating a role. But I can't imagine
what that would be because we throw away its data (the index data
structures are replaced and inline revision data is replaced via
the chunk cache) and since 00changelog.i.a is a copy of
00changelog.i, file content should be identical, so there should
be no meaninful file integrity checking at play. I think this was
all just sub-optimal code.

changelog: disable delta chains
This patch disables delta chains on changelogs. After this patch, new
entries on changelogs - including existing changelogs - will be stored
as the fulltext of that data (likely compressed). No delta computation
will be performed.
An overview of delta chains and data justifying this change follows.
Revlogs try to store entries as a delta against a previous entry (either
a parent revision in the case of generaldelta or the previous physical
revision when not using generaldelta). Most of the time this is the
correct thing to do: it frequently results in less CPU usage and smaller
storage.
Delta chains are most effective when the base revision being deltad
against is similar to the current data. This tends to occur naturally
for manifests and file data, since only small parts of each tend to
change with each revision. Changelogs, however, are a different story.
Changelog entries represent changesets/commits. And unless commits in a
repository are homogonous (same author, changing same files, similar
commit messages, etc), a delta from one entry to the next tends to be
relatively large compared to the size of the entry. This means that
delta chains tend to be short. How short? Here is the full vs delta
revision breakdown on some real world repos:
Repo % Full % Delta Max Length
hg 45.8 54.2 6
mozilla-central 42.4 57.6 8
mozilla-unified 42.5 57.5 17
pypy 46.1 53.9 6
python-zstandard 46.1 53.9 3
(I threw in python-zstandard as an example of a repo that is homogonous.
It contains a small Python project with changes all from the same
author.)
Contrast this with the manifest revlog for these repos, where 99+% of
revisions are deltas and delta chains run into the thousands.
So delta chains aren't as useful on changelogs. But even a short delta
chain may provide benefits. Let's measure that.
Delta chains may require less CPU to read revisions if the CPU time
spent reading smaller deltas is less than the CPU time used to
decompress larger individual entries. We can measure this via
`hg perfrevlog -c -d 1` to iterate a revlog to resolve each revision's
fulltext. Here are the results of that command on a repo using delta
chains in its changelog and on a repo without delta chains:
hg (forward)

! wall 1.160200 comb 1.170000 user 1.160000 sys 0.010000 (best of 9)
The data clearly shows that it takes less wall and CPU time to resolve
revisions when there are no delta chains in the changelogs, regardless
of the direction of traversal. Furthermore, not using a delta chain
means that fulltext resolution in reverse is as fast as iterating
forward. So not using delta chains on the changelog is a clear CPU win
for reading operations.
An example of a user-visible operation showing this speed-up is revset
evaluation. Here are results for
`hg perfrevset 'author(gps) or author(mpm)'`:
hg
! wall 1.655506 comb 1.660000 user 1.650000 sys 0.010000 (best of 6)

! wall 17.311033 comb 17.300000 user 17.260000 sys 0.040000 (best of 3)
What about 00changelog.i size?
Repo Delta Chains No Delta Chains
hg 7,033,250 6,976,771
mozilla-central 82,978,748 81,574,623
mozilla-unified 88,112,349 86,702,162
pypy 20,740,699 20,659,741
The data shows that removing delta chains from the changelog makes the
changelog smaller.
Delta chains are also used during changegroup generation. This
operation essentially converts a series of revisions to one large
delta chain. And changegroup generation is smart: if the delta in
the revlog matches what the changegroup is emitting, it will reuse
the delta instead of recalculating it. We can measure the impact
removing changelog delta chains has on changegroup generation via
`hg perfchangegroupchangelog`:
hg
! wall 1.589245 comb 1.590000 user 1.590000 sys 0.000000 (best of 7)

! wall 5.415455 comb 5.420000 user 5.410000 sys 0.010000 (best of 3)
The data shows eliminating delta chains makes the changelog part of
changegroup generation slower. This is expected since we now have to
compute deltas for revisions where we could recycle the delta before.
It is worth putting this regression into context of overall changegroup
times. Here is the rough total CPU time spent in changegroup generation
for various repos while using delta chains on the changelog:
Repo CPU Time (s) CPU Time w/ compression
hg 4.50 7.05
mozilla-central 111.1 222.0
pypy 28.68 75.5
Before compression, removing delta chains from the changegroup adds
~4.4% overhead to hg changegroup generation, 1.3% to mozilla-central,
and 2.0% to pypy. When you factor in zlib compression, these percentages
are roughly divided by 2.
While the increased CPU usage for changegroup generation is unfortunate,
I think it is acceptable because the percentage is small, server
operators (those likely impacted most by this) have other mechanisms
to mitigate CPU consumption (namely reducing zlib compression level and
pre-generated clone bundles), and because there is room to optimize this
in the future. For example, we could use the nullid as the base revision,
effectively encoding the full revision for each entry in the changegroup.
When doing this, `hg perfchangegroupchangelog` nearly halves:
mozilla-unified
! wall 21.168075 comb 21.170000 user 21.130000 sys 0.040000 (best of 3)
! wall 11.196461 comb 11.200000 user 11.190000 sys 0.010000 (best of 3)
This looks very promising as a future optimization opportunity.
It's worth that the changes in test-acl.t to the changegroup part size.
This is because revision 6 in the changegroup had a delta chain of
length 2 before and after this patch the base revision is nullrev.
When the base revision is nullrev, cg2packer.deltaparent() hardcodes
the *previous* revision from the changegroup as the delta parent.
This caused the delta in the changegroup to switch base revisions,
the delta to change, and the size to change accordingly. While the
size increased in this case, I think sizes will remain the same
on average, as the delta base for changelog revisions doesn't matter
too much (as this patch shows). So, I don't consider this a regression.

What about 00changelog.i size?
Repo Delta Chains No Delta Chains

pypy 20,740,699 20,659,741
The data shows that removing delta chains from the changelog makes the
changelog smaller.
Delta chains are also used during changegroup generation. This
operation essentially converts a series of revisions to one large
delta chain. And changegroup generation is smart: if the delta in
the revlog matches what the changegroup is emitting, it will reuse
the delta instead of recalculating it. We can measure the impact
removing changelog delta chains has on changegroup generation via
`hg perfchangegroupchangelog`:
hg

! wall 1.788060 comb 1.790000 user 1.790000 sys 0.000000 (best of 6)

! wall 5.415455 comb 5.420000 user 5.410000 sys 0.010000 (best of 3)
The data shows eliminating delta chains makes the changelog part of
changegroup generation slower. This is expected since we now have to
compute deltas for revisions where we could recycle the delta before.
It is worth putting this regression into context of overall changegroup
times. Here is the rough total CPU time spent in changegroup generation
for various repos while using delta chains on the changelog:
Repo CPU Time (s) CPU Time w/ compression
hg 4.50 7.05
mozilla-central 111.1 222.0
pypy 28.68 75.5
Before compression, removing delta chains from the changegroup adds
~4.4% overhead to hg changegroup generation, 1.3% to mozilla-central,
and 2.0% to pypy. When you factor in zlib compression, these percentages
are roughly divided by 2.
While the increased CPU usage for changegroup generation is unfortunate,
I think it is acceptable because the percentage is small, server
operators (those likely impacted most by this) have other mechanisms
to mitigate CPU consumption (namely reducing zlib compression level and
pre-generated clone bundles), and because there is room to optimize this
in the future. For example, we could use the nullid as the base revision,
effectively encoding the full revision for each entry in the changegroup.
When doing this, `hg perfchangegroupchangelog` nearly halves:
mozilla-unified
! wall 21.168075 comb 21.170000 user 21.130000 sys 0.040000 (best of 3)
! wall 11.196461 comb 11.200000 user 11.190000 sys 0.010000 (best of 3)
This looks very promising as a future optimization opportunity.
It's worth that the changes in test-acl.t to the changegroup part size.
This is because revision 6 in the changegroup had a delta chain of
length 2 before and after this patch the base revision is nullrev.
When the base revision is nullrev, cg2packer.deltaparent() hardcodes
the *previous* revision from the changegroup as the delta parent.
This caused the delta in the changegroup to switch base revisions,
the delta to change, and the size to change accordingly. While the
size increased in this case, I think sizes will remain the same
on average, as the delta base for changelog revisions doesn't matter
too much (as this patch shows). So, I don't consider this a regression.

codemod: join the auto-formatter party
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.

codemod: join the auto-formatter party
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.
