Added return types to functions that just return literal strings, ints,
or bools.
Used the following python script:
```
from re import sub
# find **/*.py > files.txt
for file in open("files.txt"):
source = open(file.strip()).read()
"""
def foo(x: int, y):
return f"1234"
"""
# Literal strings
source = sub(
r"def ([^\n>]+):(\n\s+)(return [rf]?(\"[^\"]*\"|'[^']*')\n)",
r"def \1 -> str:\2\3",
source,
)
# Literal ints
source = sub(
r"def ([^\n>]+):(\n\s+)(return \d+\n)",
r"def \1 -> int:\2\3",
source,
)
# Literal bools
source = sub(
r"def ([^\n>]+):(\n\s+)(return (True|False)\n)",
r"def \1 -> bool:\2\3",
source,
)
open(file.strip(), "w").write(source)
```
Added a bunch of return types. (Took the HttpResponseBase from the root class.) `mypy` no errors
two super-duper low-lift files (just adding `None` return types).
Part of Hackweek 2025 typing efforts ⭐
# Summary Grabbed this because I thought it would just be a bunch of easy missing-return-type errors. It turns out, when you add return types you expose other errors. Who'd've thunk? 😅 Here's the complicating factor: the plugin framework uses `Request`. `RequestFactory` returns `WSGIRequest`. `BaseTestCase.make_request` returns `HttpRequest`. Our typing revealed that a bunch of incorrect `Request-ish` types were being passed around. This PR changes the incompatible frameworks to `MagicMock`, which more correctly limits behavior to what is explicitly defined (and not what would not actually happen due to type differences). # Test Plan `mypy tests/sentry_plugins` ==> no errors `pytest tests/sentry_plugins/**` ==> `162 passed, 1 skipped`
was picking through the files with only one error. this got a lot of the initially-known-to-mypy errors fixed... but I'm concerned that it exposed more errors that I don't have a good way of exposing, since I didn't stick to a single easily-added-to-pyproject module. I think in the future I'll probably stick to codemods or modules.
Just needed to type the setup functions! `rg -l 'def setUp\(self\):' tests/apidocs | xargs sed -i '' -E -e 's/def setUp\(self\):/def setUp(self) -> None:/'` # Test Plan Ran `mypy tests/apidocs`, no errors
# Summary 59 files, newly typed! # Test Plan `mypy` no errors --------- Co-authored-by: getsantry[bot] <66042841+getsantry[bot]@users.noreply.github.com>
# Summary Developed a new pattern that let me run through some files I identified as low-lift quickly: * Added `"sentry.*", "test.*"` to `pyproject.toml` * Developed a list of expected-to-be-low-lift files from mypy output * Mostly files that were in test directory, only had one error, or only needed `None` return types * Then repeatedly ran `mypy <big_list_of_files>` and whittled that down * Before pushing the branch, I removed the changes to `pyproject.toml` Result is that I can confidently say that this PR successfully types ~150 new files. # Test Plan Reverted changes to `pyproject.toml` and ran `mypy` to ensure the new types had no effect on steady-state — no errors!
These magic test functions always have the same returns! I already messed with some in `tests/sentry`; worth expanding to all of `tests` ``` rg 'def tearDown' tests -ls | xargs sed -i '' 's/def tearDown(self):/def tearDown(self) -> None:/' rg 'def setUp' tests -ls | xargs sed -i '' 's/def setUp(self):/def setUp(self) -> None:/' ```
Follows #97998 Turns out there's a utility function to convert `HttpRequest` to `Request`! Better to use the normal requests than full mocks.
completely types an additional 65 files with low errors-per-file count
This was more complex than expected 😅
