* Remove `typing.Self` workaroundYurii Karabas2023-02-081-8/+4
| | | | | | | | | | | | Remove ``typing.Self`` workaround, now using :pep:`673` for most methods that return ``Self``. Pull request courtesy Yurii Karabas. Fixes: #9254 Closes: #9255 Pull-request: https://github.com/sqlalchemy/sqlalchemy/pull/9255 Pull-request-sha: 2947df8ada79f5c3afe9c838e65993302199c2f7 Change-Id: Ic32015ad52e95a61f3913d43ea436aa9402804df

* Try running pyupgrade on the codeFederico Caselli2022-11-161-3/+1
| | | | | | | | command run is "pyupgrade --py37-plus --keep-runtime-typing --keep-percent-format <files...>" pyupgrade will change assert_ to assertTrue. That was reverted since assertTrue does not exists in sqlalchemy fixtures Change-Id: Ie1ed2675c7b11d893d78e028aad0d1576baebb55
* inline mypy config; files ignoring type errors for the momentMike Bayer2022-04-281-0/+2
| | | | | | | | | | | | | | | | | | | to simplify pyproject.toml change the remaining files that aren't going to be typed on this first pass (unless of course someone wants to type some of these) to include # mypy: ignore-errors. for the moment, only a handful of ORM modules are to have more type checking implemented. It's important that ignore-errors is used and not "# type: ignore", as in the latter case, mypy doesn't even read the existing types in the file, which makes it impossible to type any files that refer to those modules at all. to simplify ongoing typing work use inline mypy config for remaining files that are "done" for now, indicating the level of type checking they currently have.

* Properly type _generative, decorator, public_factoryFederico Caselli2021-12-301-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Good new is that pylance likes it and copies over the singature and everything. Bad news is that mypy does not support this yet https://github.com/python/mypy/issues/8645 Other minor bad news is that non_generative is not typed. I've tried using a protocol like the one in the comment but the signature is not ported over by pylance, so it's probably best to just live without it to have the correct signature. notes from mike: these three decorators are at the core of getting the library to be typed, more good news is that pylance will do all the things we like re: public_factory, see https://github.com/microsoft/pyright/issues/2758#issuecomment-1002788656 . For @_generative, we will likely move to using pep 673 once mypy supports it which may be soon. but overall having the explicit "return self" in the methods, while a little inconvenient, makes the typing more straightforward and locally present in the files rather than being decided at a distance. having "return self" present, or not, both have problems, so maybe we will be able to change it again if things change as far as decorator support. As it is, I feel like we are barely squeaking by with our decorators, the typing is already pretty out there. Change-Id: Ic77e13fc861def76a5925331df85c0aa48d77807 References: #6810
