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.

Now that the 'vfs' classes moved in their own module, lets use the new module
directly. We update code iteratively to help with possible bisect needs in the
future.
This patch introduces a new 'raw' argument (defaults to False) to revlog's
revision() and _addrevision() methods.
When the 'raw' argument is set to True, it indicates the revision data should be
handled as raw data by the flagprocessor.
Note: Given revlog.addgroup() calls are restricted to changegroup generation, we
can always set raw to True when calling revlog._addrevision() from
revlog.addgroup().
A future patch will be moving manifest creation to be inside manifestlog as part
of improving our cache guarantees. bundlerepo and unionrepo currently rely on
being able to hook into manifest creation, so let's temporarily move the actual
manifest creation to a helper function for them to intercept.
In the future manifest.manifest() will disappear entirely and this can
disappear.
The unionrepository have to do some special magic to handle linkrev of the
unioned filerev and manifestrev. That logic was done from a repoview and
obsolescence marker affecting bundled changeset could lead to a crash. We now
ensure we operate on unfiltered repository.
The home of 'Abort' is 'error' not 'util' however, a lot of code seems to be
confused about that and gives all the credit to 'util' instead of the
hardworking 'error'. In a spirit of equity, we break the cycle of injustice and
give back to 'error' the respect it deserves. And screw that 'util' poser.
For great justice.
When general delta is enabled, the base is actually meaningful and should be
used. With general delta is enabled, test-unionrepo.t crash without this fix.
Since Python 2.7.9, "os.path.join(path, '')" doesn't add "os.sep" at
the end of UNC path (see issue4557 for detail).
This makes unionrepo incorrectly work, if:
1. cwd is the root of UNC share (e.g. "\host\share"), and
2. mainreporoot is near cwd (e.g. "\host\sharefoo\repo")
- host of UNC path is same as one of cwd
- share of UNC path starts with one of cwd
3. "repopath" isn't specified in URI (e.g. "union:path/to/repo2")
For example:
$ hg --cwd \host\share -R \host\sharefoo\repo incoming union:path\to\repo2
In this case:
- os.path.join(r"\host\share", "") returns r"\host\share",
- r"\host\sharefoo\repo".startswith(r"\host\share") returns True, then
- r"foo\repo" is treated as repopath of unionrepo instead of
r"\host\sharefoo\repo"
This causes failure of combining "\host\sharefoo\repo" and another
repository: in addition to it, "\host\share\foo\repo" may be combined
with another repository, if it accidentally exists.
This patch uses "pathutil.normasprefix()" to ensure "os.sep" at the
end of cwd safely, even with some problematic encodings, which use
0x5c (= "os.sep" on Windows) as the tail byte of some multi-byte
characters.
BTW, normalization before "pathutil.normasprefix()" isn't needed in
this case, because "os.getcwd()" always returns normalized one.
The iscensored method will be used by the exchange layer to reject
nonconforming deltas involving censored revisions (and to produce
conforming deltas).

This change touches every module in which repository.sopener was being used, and
changes it for the equivalent repository.svfs.
It should now be possible to remove localrepo.sopener.
Some extensions set configuration settings that showed up in 'hg showconfig
--debug' with 'none' as source. That was confusing.
Instead, they will now tell which extension they come from.
This change tries to be consistent and specify a source everywhere - also where
it perhaps is less relevant.
This makes possible to use unionrevlog class with subclasses of revlog that
override revlog's 'revision' and 'revdiff' methods. In particular this change
is necessary to implement manifest compression, as it allows extension to
replace manifest class and override 'revision' amd 'revdiff' methods there.
unionrepo is just like bundlerepo without bundles.
The implementation is very similar to bundlerepo, but I don't see any obvious
way to generalize it.
Some most obvious use cases for this would be log and diff across local repos,
as a kind of preview of pulls, for instance:
$ hg -R union:repo1+repo2 heads
$ hg -R union:repo1+repo2 log -r REPO1REV -r REPO2REV
$ hg -R union:repo1+repo2 log -r '::REPO1REV-::REPO2REV'
$ hg -R union:repo1+repo2 log -r 'ancestor(REPO1REV,REPO2REV)'
$ hg -R union:repo1+repo2 diff -r REPO1REV -r REPO2REV
This is going to be used in RhodeCode, and Bitbucket already uses something
similar. Having a core implementation would be beneficial.
