Include "t" in ABI tag for --disable-gil builds #109740
Description
Activity
Yep, I'm fine with "t" tag. Try to write a test to ensure that if Python is built with NoGIL, the tag is present. Maybe added it in test_sys which can check sys.abiflags.

on Sep 27, 2023 This is implemented, although there are still some follow-up tasks.
Feature or enhancement
Context:
The
--disable-gilbuilds will have a different version specific ABI from the default CPython 3.13 builds due to reference counting differences and other changes. This should be indicated by a "t" (for "threading") in the ABI tag.On POSIX, this is achieved by setting the
ABIFLAGSvariable, which feeds into the sysconfigEXT_SUFFIXandSOABIvariables. The version specific shared libraries would look like:package.cpython-313t-darwin.soOn Windows, this is achieved by setting
PYD_TAGGED_SUFFIX, which feeds into the sysconfigEXT_SUFFIX. The shared libraries using the version specific ABI would look like:_package.cp313t-win_amd64.pydNote that this does not address and is independent of the stable ABI. There's ongoing discussion about how best to support the stable ABI in
