Description Tomáš Hrnčiar 2020-10-20 13:25:27 UTC 
rpm fails to build with Python 3.10.0a1.

Here is the error, seems like RPM has a problem with detecting the double-digit version of Python 3.10.

configure: error: Package requirements (python-3.1) were not met:

Package 'python-3.1', required by 'virtual:world', not found

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.10/fedora-rawhide-x86_64/01713540-rpm/

For all our attempts to build rpm with Python 3.10, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/rpm/

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.10:
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/

Let us know here if you have any questions.

Python 3.10 will be included in Fedora 35. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.10.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
Comment 1 Miro Hrončok 2020-10-20 13:39:31 UTC 
This is a problem in automake. The documentation says: 

PYTHON_VERSION
The Python version number, in the form major.minor (e.g., ‘2.5’). This is currently the value of ‘sys.version[:3]’.

https://www.gnu.org/software/automake/manual/html_node/Python.html



The code seem to actually use this naïve construct:

[automake (master)]$ rg -F 'sys.version'
m4/python.m4
94:    [am_cv_python_version=`$PYTHON -c "import sys; sys.stdout.write(sys.version[[:3]])"`])
127:    if python_implementation() == 'CPython' and sys.version[[:3]] == '2.7':
230:# word of sys.version), in order to cope with versions such as 2.2c1.

doc/automake.texi
7861:@samp{sys.version[:3]}.

t/python-virtualenv.sh
46:py_version=$(python -c 'import sys; print("%u.%u" % tuple(sys.version_info[:2]))')

t/python-vars.sh
31:PYTHON_VERSION=$($PYTHON -c 'import sys; print(sys.version[:3])') || exit 1




Patrik, could you please report this to upstream? I am not subscribed to their mailing lists.
Comment 2 Miro Hrončok 2020-10-22 20:10:10 UTC 
Here's my attempted fix: https://src.fedoraproject.org/rpms/automake/pull-request/3

It moves the build of the rpm package further, but there are some new failures (most likely unrelated):

https://copr.fedorainfracloud.org/coprs/g/python/python3.10/build/1717510/
Comment 3 Miro Hrončok 2020-10-23 07:15:55 UTC 
The rpm failures are mostly:

error: /build/RPMS/noarch/....rpm: open failed: No such file or directory
error: cannot open ... index using sqlite - Operation not permitted (1)
error: cannot open Packages database in /var/lib/rpm
error: can't create transaction lock on /var/lib/rpm/.rpm.lock (No such file or directory)
error: failed to stat /data/SPECS/....spec: No such file or directory
error: open of /build/RPMS/noarch/....rpm failed: No such file or directory
error: package ... is not installed
error: Unable to open sqlite database /var/lib/rpm/rpmdb.sqlite: unable to open database file
Comment 4 Miro Hrončok 2020-10-23 07:44:14 UTC 
I get the same failures when I try to build rpm in a clean copr (first build with defaults, second with mock bootstrap):

https://copr.fedorainfracloud.org/coprs/churchyard/rpm-experiment/builds/

Same results with local mock build.

The test failures are not automake nor Python 3.10 related at all.

My proposed automake fix should be enough to fix the build failure.
Comment 5 Panu Matilainen 2020-10-23 08:53:42 UTC 
Ough, something broke fakechroot big time. I remember seeing something about recent glibc changes breaking this and that, and whenever something changes, fakechroot is one of the first things to blow up...

If problem still persists, please make note of it in this bug report.
Comment 8 Miro Hrončok 2020-11-03 12:34:10 UTC 
This needs to be backported, because developers will use automake on stable Fedoras to generate tarballs to be used in rawhide packages.
