util: add a comment to suppress a PyCharm warning about a PEP 8 violation
Slowly trying to get rid of silly warnings, so that real problems aren't hidden.
keepalive: fix a signature mismatch for a http.client.HTTPResponse subclass
Also flagged by PyCharm. This is checked by pytype too, so I'm not sure why it
misses this. I verified in py36 that this argument is documented for the
function, so maybe this is py2 legacy.
profiling: document the py-spy value for `profiling.type`
The feature was not visible otherwise.
unionrepo: fix mismatches with revlog classes
This is a subset of
cfd30df0f8e4, applied to `unionrepository`. There are none
of the `write()` method overrides here, like `bundlerepository`.
With these changes, pytype flags the `unionrevlog` constructor:
File "/mnt/c/Users/Matt/hg/mercurial/unionrepo.py", line 55, in __init__:
No attribute '_revlog' on mercurial.changelog.changelog [attribute-error]
Called from (traceback):
line 207, in __init__
File "/mnt/c/Users/Matt/hg/mercurial/unionrepo.py", line 55, in __init__:
No attribute '_revlog' on mercurial.revlog.revlog [attribute-error]
Called from (traceback):
line 232, in __init__
But it turns out that both `changelog.changelog` and `revlog.revlog` do have a
`target` attribute, so they wouldn't trip over this. It seems weird that the
second caller to be flagged is passing the private `_revlog`, but maybe that's
how it needs to be.
typing: make `unionrepository` subclass `localrepository` while type checking
This is the same change as
9d4ad05bc91c made for `bundlerepository`, for the
same reasons.
Also, add a comment here to suppress the PyCharm warning that the superclass
constructor is not called, that is new now that there's a simulated superclass.
That lack of a call is by design- `makeunionrepository()` does magic that
PyCharm isn't aware of. But PyCharm has been better at catching problems than
pytype in a lot of cases, so I'd like to reduce the bogus things it flags, to
make the real issues stand out.
revlog: make `clearcaches()` signature consistent with ManifestRevlog
I'm not sure if this a newly added bug, because of using a different version of
pytype, or if the recent work around avoiding the zope interface types in the
type checking phase (see
5eb98ea78fd7 and friends)... but pytype 2023.11.21
started flagging this series since it was last pushed ~6 weeks ago:
File "/mnt/c/Users/Matt/hg/mercurial/bundlerepo.py", line 204, in <module>:
Overriding method signature mismatch [signature-mismatch]
Base signature: 'def mercurial.manifest.ManifestRevlog.clearcaches(self, clear_persisted_data: Any = ...) -> None'.
Subclass signature: 'def mercurial.revlog.revlog.clearcaches(self) -> None'.
Not enough positional parameters in overriding method.
Maybe the multiple inheritance in `bundlerepo.bundlemanifest` is bad, but it
seems like a `ManifestRevlog` is-a `revlog`, even though the class hierarchy
isn't coded that way. Additionally, it looks like `revlog.clearcaches()` is
dealing with some persistent data, so maybe this is useful to have there anyway.
Also sprinkle some trivial type hints on the method, because there are other
`clearcaches()` definitions in the codebase with these hints, and I don't feel
like waiting for another pytype run to see if it cares that specifically about
the signature matching.
bundlerepo: fix mismatches with repository and revlog classes
Both pytype and PyCharm complained that `write()` and `_write()` in the
bundlephasecache class aren't proper overrides- indeed they seem to be missing
an argument that the base class has.
PyCharm and pytype also complained that the `revlog.revlog` class doesn't have a
`_chunk()` method. That looks like it was moved from revlog to `_InnerRevlog`
back in
e8ad6d8de8b8, and wasn't caught because this module wasn't type checked.
However, I couldn't figure out a syntax with `revlog.revlog._inner._chunk(self, rev)`,
as it complained about passing too many args. `bundlerevlog._rawtext()` uses
this `super(...)` style to call the super class, so hopefully that works, even
with the wonky dynamic subclassing. The revlog class needed the `_InnerRevlog`
field typed because it isn't set in the constructor.
Finally, the vfs type hints look broken. This initially failed with:
File "/mnt/c/Users/Matt/hg/mercurial/bundlerepo.py", line 65, in __init__: Function readonlyvfs.__init__ was called with the wrong arguments [wrong-arg-types]
Expected: (self, vfs: mercurial.vfs.vfs)
Actually passed: (self, vfs: Callable)
Called from (traceback):
line 232, in dirlog
line 214, in __init__
I don't see a raw Callable, but I tried changing some of the vfs args to be typed
as `vfsmod.abstractvfs`, but that class doesn't have `options`, so it failed
elsewhere. `readonlyvfs` isn't a subclass of `vfs` (it's a subclass of
`abstractvfs`), so I'm not sure how to handle that. It would be a shame to have
to make a union of vfs subclasses (but not all of them have `options` either).
