Summary

We've recently started seeing builds failing with following errors:

failed to clone (7.70-506.azl3.noarch) from RPM repo

This seems to be related with invalid parsing of the tdnf provides output where the tool's regex failed to take a potential : into the account. A few lines above the mentioned error, we can see TDNF finding the right package:

time="2024-09-30T21:52:54Z" level=debug msg="Executing: [tdnf provides perl(ExtUtils::MakeMaker) --releasever=3.0 --disablerepo=* --enablerepo=toolchain-repo]"
time="2024-09-30T21:52:54Z" level=debug msg="tdnf search for provide 'perl(ExtUtils::MakeMaker)':
Loaded plugin: tdnfrepogpgcheck
[using capability match for 'perl(ExtUtils::MakeMaker)']
perl-ExtUtils-MakeMaker-2:7.70-506.azl3.noarch : Create a module Makefile
Repo	 : toolchain-repo

The : character in 2:7.70-506.azl3.noarch is what confused the regex.

The current (as of 09/30/2024) version of TDNF (3.5.6) is printing the versions without the epoch and that's why we haven't hit this issue until now. It seems that the bump to version 3.5.8 added the epoch number to the tdnf provides output.

Sample output for 3.5.6:

root [ / ]# tdnf provides 'perl(ExtUtils::MakeMaker)'
Loaded plugin: tdnfrepogpgcheck
[using capability match for 'perl(ExtUtils::MakeMaker)']
perl-ExtUtils-MakeMaker-7.70-506.azl3.noarch : Create a module Makefile
Repo     : azurelinux-official-base

Notice no epoch in 7.70-506.azl3.noarch.

Does this affect the toolchain?

No.
