Would it be possible to add a __file__ attribute? Victor On Tue, Sep 28, 2021 at 2:47 PM Pablo Galindo Salgado <pablogsal@gmail.com> wrote:

One interesting consequence of what Eric mentioned (They have a different loader and repr. Also, frozen modules do not have __file__ set (and __path__ is always []).) is that frozen modules don't have a `__file__` attribute IIRC and therefore tracebacks won't include the source.

Hi Eric,
Which stdlib modules are currently frozen? If I really want to hack site.py or os.py for whatever reason, I just have to use "python3 -X frozen_modules=off"?
1. always default to "on" (the annoyance for contributors isn't big enough?)

We've frozen most of the stdlib modules imported during "python -c pass" [1][2], to make startup a bit faster. Import of those modules is controlled by "-X frozen_modules=[on|off]". Currently it defaults to "off" but we'd like to default to "on". The blocker is the impact on contributors. I expect many will make changes to a stdlib module and then puzzle over why those changes aren't getting used. That's an annoyance we can avoid, which is the point of this thread.
Possible solutions:
1. always default to "on" (the annoyance for contributors isn't big enough?) 2. default to "on" if it's a PGO build (and "off" otherwise) 3. default to "on" unless running from the source tree
Thoughts?

[1] https://bugs.python.org/issue45020 [2] FWIW, we may end up also freezing the modules imported for "python -m ...", along with some other commonly used modules (like argparse). That is a separate discussion. _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-leave@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/4ESW3NNO...
