Summary

Continues the Python 3.15 upgrade decomposition from #8954.

Pass globals['__name__'] through the existing compilation-warning path for string inputs to eval() and exec(), matching CPython's _PyRun_String behavior.

This lets warning filters match the supplied module instead of incorrectly falling back to <string>. A missing name still uses filename fallback; an explicitly supplied None retains CPython's warning-suppression behavior. Typed compile/symtable/interactive entrypoints remain intact, including compile(module=...) validation.

The behavior change is limited to two native files. It does not change warning ordering, numeric-warning metadata, parser recovery, or existing filename/callback handling. This does not incorporate the separate unmerged work in #9282.

A test-marker-only follow-up removes the now-stale expectedFailure on BuiltinTest.test_exec_filter_syntax_warnings_by_module using the canonical scripts/update_lib migrate workflow. The complete canonical method body, fixture and every other local adaptation remain unchanged. Hosted RustPython CI on the initial head reported that method as an unexpected success both initially and on its own rerun; that old run remains failed, not green.

Validation

Tested native base: ad8bd18f341445761fc57b1080db6e6e8e0e10e7. The following native/local results were established before the test-marker-only follow-up; native source is byte-for-byte unchanged.

• Fresh source-bound default-features + capi CLI builds for baseline and candidate, with actual native compilation inputs verified, including host_env/CAPI.
• Eleven bounded external observations against CPython 3.15.0, using canonical source contract d220409a13b77de7a6c30abe16ea90db01528edc: baseline 5/11, candidate and oracle 11/11. All candidate observation records match the oracle, including captured warning messages.
• Six eval/exec differences fixed: named-module filtering, rejection of incorrect filename fallback, and explicit-None suppression. Missing-name fallback and three compile-only controls remain unchanged.
• VM checks with and without threading, VM test-target compilation check, strict Clippy for VM all-targets with threading, and normal changed-file hooks passed.

The observations use fresh owned dictionaries and fixed literal expressions/assignments, in independent -B processes with 120-second timeouts and 1 GiB address-space limits. They are external finite observations, not execution of canonical test modules, the ZIP fixture, or the full suite. The CAPI-linked CLI builds do not constitute CAPI runtime validation; Rust test targets were checked, not executed.

The updater-generated follow-up has passed source-identity checks and normal changed-file hooks. It does not add a native build or a full local suite run. New-head hosted CI is pending.
