New submission from Miro Hrončok <[email protected]>:
In Fedora, when building Python 3.11.0a2 with Python 3.11.0a2 for regen, we
found that regen-frozen fails.
It can be reproduced either on the v3.11.0a2 tag or on the main branch.
On tag v3.11.0a2 with 3.11.0a2 installed in $PATH:
# in root of cpython local clone:
$ git clean -fdx
$ mkdir -p build/optimized
$ cd build/optimized
$ ../../configure
$ make regen-all PYTHON_FOR_REGEN=python3.11
...
ERROR: missing _freeze_module
On the main branch:
# in root of cpython local clone:
$ git clean -fdx
$ mkdir -p build/optimized
$ cd build/optimized
$ ../../configure
$ make
$ make regen-all PYTHON_FOR_REGEN=./python
(success)
However, the working tree is dirty:
$ git diff
diff --git a/Parser/parser.c b/Parser/parser.c

And if we install Python somewhere:
$ make
$ make install DESTDIR=/tmp/python
And use that one again for regen:
$ cd ../..
$ git clean -fdx
$ mkdir -p build/optimized
$ cd build/optimized
$ ../../configure
$ make regen-all PYTHON_FOR_REGEN=/tmp/python/usr/local/bin/python3.11

It fails. I've isolated the failure to:
$ make regen-frozen PYTHON_FOR_REGEN=/tmp/python/usr/local/bin/python3.11
/tmp/python/usr/local/bin/python3.11 ../../Tools/scripts/freeze_modules.py
