Fixes #4318.

Add possibly-uninitialized-attribute for attributes whose class body or initialization method can complete without assigning them. Report the error at the definition. The default preset ignores it, and the strict preset enables it. Users can configure it separately from missing-attribute.

Track attribute initialization separately from local-variable bindings. Check class-body definitions independently. Combine method assignments leniently, so an unconditional helper assignment can establish initialization. Exclude conditional method definitions, stub files, nested-function assignments, inherited attributes, and instance attributes with a __getattr__ fallback. Account for explicit returns, deletions, and paths that terminate with Never or NoReturn.

Preserve exact deferred termination conditions through 16 requirements. Above that limit, retain one key per requirement and remove duplicates. This prevents exponential growth across branch joins. The conservative approximation can produce false positives above the limit.

Changes to local-variable initialization are in #5323. Changes to reachability after while True are in #5324. Both PRs are based directly on main. The retry-loop regression retains a passing test with a bug marker. After #5324 lands, remove that marker and its expected initialization error when rebasing this PR.

Validation:

  • 723 related tests passed.
  • Regression tests cover the proof limit, 1000 successive joins, and branch-heavy constructors and helpers with the diagnostic enabled and disabled.
  • Formatting and lint checks passed. Clippy reports existing warnings in unchanged code.

hmm, for this one I think we should error where the attribute is declared, not where it is accessed. it could be kind of tricky because we would need to handle situations like this to avoid false positives.

if something:
   self.x = 1
else:
   self.x = 2

I guess it would be similar to the logic around possibly-unbound variables

Looks like there's a failing test. It might be a flaky test or temporary failure on main. Could you rebase and double check?

Hey Asuka, a few more comments here. I think we're getting close though

The main things are:

  • attrs defined on base classes are false positives
  • methods ending in NoReturn are false positives
  • assignments in nested functions are too permissive at counting initialization

Let me know if you have any questions or disagree with anything here :)

We never check to see if an attribute is defined on a base class, so something like this would fail:

class Base:
  timeout = 10

class Child(Base):
  def __init__(self, t: int | None = None) -> None:
    if t is not None:
      self.timeout = t  # error, even though it alwas exists in `Base`

The same thing happens with super().__init__()

We should be able to fix this by skipping the error when a base other than object defines the name

Can we also add a test for this one

Tests are looking great so far, but I have a few more to request:

  • inherited attributes
  • try/except/finally and with in __init__
  • match statements
  • while True with return
  • nested def
  • del self.x
  • TYPE_CHECKING and sys.version_info checks in a class body (these do work today, but nothing tests it)
  • dataclass __post_init__
  • __init_subclass__
  • a for loop variable left behind in a class body

Hey Asuka, thanks for making the changes. I found a big issue in this version around memory blowup. Maybe it would be worth splitting up to get parts of it landed (such as landing tests first with bug markers or comments, then smaller PRs that fix those as they add implementation)? I was trying to figure out if I could give you branch write access so you can use gh-stack if you want, but I'm not sure where that setting is (or if we even have it on Meta repositories). Up to you if you'd like to do the split or keep working on one PR here.

It looks like this is replacing determine_definition_status down below, which no longer counts termination keys from all branches, so a for loop body ending an expression statement suppressed the zero-iteration path:

def f(xs: list[int]) -> int:
    for x in xs:
        y = x
        time.sleep(1)
    return y   # base: nothing. new: `y` may be uninitialized [unbound-name]

This is correct, but it's a default-on change that is probably worth reviewing in its own separate PR

This adds a lot of new code to this function, re-deriving provenance the binding phase already knows about. If it's not too difficult, it might be simpler to record a function-def flag at bind time rather than here, but I'll leave it up to you on whether or not it's worth doing.

Oof, I'm getting exponential memory blowup coming from (I think) this function, which is causing Pyrefly to use much more memory.

It looks like this function clones every existing path for each branch and appends the branch's termination key, so if both sides of a join end in an expression statement, the paths double. Dedup isn't helping here because the copies differ in the appended key. Then merge_flow re-runs this for every tracked attribtue at every join in scope.rs:4264, which runs in every method body, whether or not the error kind is enabled.

A possible fix here is to keep the current condition tracking until an attribute has more than a small number of requirements (16 would get us 4 if/else blocks), then shrink each requirement to just its first key and dedup the list. After the collapse, the list can't grow past the number of distinct trailing calls in the method, so growth stays linear instead of doubling at every join. Below the cap, results are identical to what you have now. It would probably look something like

if conditions.len() > MAX_DEFERRED_PATHS {
    conditions = conditions.into_iter().map(|path| vec![path[0]]).collect();
    conditions.dedup();
}

It would also be nice to leave a comment somewhere around here mentioning that we'll report false positives above the cap.

If you see a different approach though, please feel free to try it out!

This makes sense for the Retry case, but it changes reachability globally, not just for attribute tracking: statements after a break-less while True now get unreachable warnings, e.g. the defensive raise after a retry loop (test/paramspec.rs). Could this go in its own diff with direct tests? It would need a test for the warning after the loop, plus one for the environment-dependent while case in stmt.rs:1460 which has no dedicated test.

The doc says "Any defining method or the class body can establish initialization", but a conditional class-body definition never merges with methods. This still reports at the class body:

class C:
    if cond: x = 1
    def __init__(self): self.x = 2

Reporting here seems right to me, since C.x can fail regardless of __init__. If that's intended, could the doc say only methods combine, and could you add this case as a test?
