Changing the default in Python was discussed multiple times over the
last 20 years. Every time, it was said that it's convenient and it's
not worth it to break use cases to increase the default security.
Python 3.4 already has -I (isolated mode) which imply Python 3.11 -P
option, but it also impli

How can someone reproduce the issue? I was asked by a developer
running Ubuntu. Is there an easy way to:
(*) Get Fedora 36
(*) Build PyPy 2.7 for 32-bit: can it be done on x86-64? What is the
command line for that?

Congratulations, this change impacted tons of packages! That's also a
nice step towards more explicit build dependencies. I understood that
it's also the purpose of the pyproject.toml file ;-)

Wow, impressive list of enhancements, that's really great! I didn't
realized that so many things were done only in 2020!
Fedora is and remains my favorite OS to develop on Python!

Build 40639489 is green, build 40790556 is red. One interesting
difference is GCC 9.2.1 upgraded to GCC 10.0.1.
I reported the bug to GCC: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93384
"redefined symbol cannot be used on reloc" smells like a GCC internal
error, rather than a bug in the Pytho

It's my favorite option. Almost 50% smaller is quite good! It would be
very efficient to have such disk space gain!
Using a ZIP file for the stdlib is commonly suggested solution
Hi Jan,
With the helper of Florian Weimer and Charalampos Stratakis, we also agreed to
test this flag in priority. I understood that it disables the LD_PRELOAD
feature: it's no longer possible to override symbols in libpython with
LD_PRELOAD. Thanks to that, the compiler can avoid PLT indirecti

Yes, the python ELF binary still uses PIE (Position Independent Executable). I
checked the patched package:

There are pyperformance results:

It's the official benchmark suite to measure the Python performance on

I ran the benchmarks on my laptop using CPU isolation (iso
