Six items from a Cin-style line-by-line pass on PR #383:
- resolve_cors_origins: list of non-string entries (`[None, 123]`) now
drops them instead of coercing to junk strings like `'None'`/`'123'`.
- will_reject: backwards-compat shim removed. Production callers always
pass `request.scheme` (Flask-guaranteed); the shim only existed for
tests/non-Flask callers and made the production code path branchier
than necessary. Tests now pass scheme explicitly.
- maybe_log: redundant `if not origin` early-return dropped. will_reject
handles missing origin (engineio's own behavior — server.py:207).
- RejectionLogger.__init__: `int(dedup_cap)` wrapped in try/except so
bad-type input falls back to DEFAULT_DEDUP_CAP instead of raising.
- web_server.py: docstring on the before_request hook explains why the
hook fires on every request (Flask doesn't scope before_request to a
path prefix; the early-return string compare is the cheapest option).
- settings.js: cors-origins URL regex tightened from `[^\s/]+` to
`[^\s/?#]+` so query/fragment chars don't pass validation. Engineio
would silently fail to match those anyway; better to flag at save.
Test changes:
- parametrize gained an explicit `scheme` column (12 cases updated).
- New explicit case: scheme-mismatch rejects (engineio compares full
`{scheme}://{host}` strings).
- `test_will_reject_falls_back_to_host_only_when_no_scheme_info`
deleted — the shim it tested is gone.
- `test_will_reject_honors_x_forwarded_host` now passes scheme info.
Net: -9 production lines, -3 test lines. Production code path is
straight-line. 603 tests pass.
