Freeze modules used during startup #145278
Description
Feature or enhancement
Proposal:
This should be encodings, which was't frozen due to the lack of support for partially frozen packages, and linecache, which is used when running in interactive mode.
Has this already been discussed elsewhere?

@FFY00, the Raspbian buildbot fails consistently after this merge.
I can send revert PR to check if this is what breaks things. Do you have a better course of action?
FFY00 commentedon Apr 16, 2026
Since the failure is only on the test that checks the used syscalls, I'd prefer to just adjust that test. I think it should be a fairly safe change, and we can adjust the approach afterwards when we have feedback from the experts on that area. I'll work on a PR for that.
pythonGH-145278: also filter mmap2 in strace_helper.filter_memory
FFY00 commentedon Apr 16, 2026
I think the issue was simply that
test.support.strace_helper.filter_memorywasn't prepared formmap2, which is used in a code path triggered by this change. I have opened GH-148648.GH-145278: also filter mmap2 in strace_helper.filter_memory (GH-148648)
