[issue31772] SourceLoader uses stale bytecode in case of equal mtime seconds

[Devin Bayer]

Devin Bayer <dev at doubly.so> added the comment:

Hello Brett, it would be nice if you would discuss this before closing. The referenced PEP will not solve my use case, because hash-based checking will not become the default.

The issue is that by default the source file loader will be returning stale bytecode and that's incorrect behavior.

If you wish to avoid the stat call you could use a higher resolution timestamp in the pyc file, or better yet add a second field indicating bytecode compilation time.
