rpmbuild -ta option no longer works

[aditigaur4]

rpmbuild -ta <tarball> complains that it fails to find the spec file. The spec file exists in the top of the unpacked directory.

root [ / ]# rpmbuild -ta slurm-24.05.4.tar.bz2
error: Failed to read spec file from slurm-24.05.4.tar.bz2

The slurm tarball in this case does have the spec file at the top:

root [ / ]# tar -xvf slurm-24.05.4.tar.bz2 | grep slurm.spec
slurm-24.05.4/slurm.spec
root [ / ]#

This is rpmbuild version 4.17 but the problem exists in 4.18 as well. Note this is mariner OS.

root [ / ]# cat /etc/os-release
NAME="Common Base Linux Mariner"
VERSION="2.0.20241029"
ID=mariner
VERSION_ID="2.0"

This same command works in rpmbuild version 4.16:

[root@341759f80574 /]# rpmbuild -ta slurm-24.05.4.tar.bz2
warning: Macro expanded in comment on line 22: %_prefix path            install path for commands, libraries, etc.

warning: Macro expanded in comment on line 209: %define _unpackaged_files_terminate_build      0

[root@341759f80574 /]# rpmbuild --version
RPM version 4.16.1.3

I did not notice any changes to this specific flag in the release notes, any help on this would be greatly appreciated,
Thank you!

Can't reproduce that here, this is almost certainly some local/distro issue. My guess is that bzip2 either missing on the system or the macro for it is pointing to a wrong thing, and in both cases that's something that should be reported on Mariner, we can't help that (and 4.17-4.18 are out of upstream support by now anyway, so converting this to a discussion).

rpm --eval "%{uncompress:slurm-24.05.4.tar.bz2}" should output something like /usr/bin/bzip2 -dc slurm-24.05.4.tar.bz2 and executing the output'ed command should work.
