#1230515 — Bug#1094364: lintian: outdated test for python3-numpy-abi

Package: lintian
Version: 2.121.1
Severity: normal
Control: affects -1 src:numpy

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Dear maintainer,

with the new major version, the minor ABI counter has reset and the virtual 
package for the NumPy ABI has been updated.

The check in lib/Lintian/Check/Binaries/Prerequisites/Numpy.pm should be 
adjusted to python3?-numpy2?-abi\d+ (note the "2").

There is an additional wrinkle that the first ABI release of NumPy 2 is 
backwards compatible with NumPy 1, so dh_numpy adds

    Depends: python3-numpy2-abi0 | python3-numpy-abi9

at the moment. This will likely change again with future ABI bumps , but until 
then, it invalidates lintian's assumption that the virtual ABI package should 
not have alternatives. 

Lastly, the explicit dependency on python3-numpy is no longer generated for 
ABI dependent packages, so the check for strictly versioned dependencies on 
python3-numpy is obsolete, too.


Cheers
Timo

Not a regression but an old bug is that the
    if (   $item->name=~ m{^usr/lib/(?:pyshared/)?python2\.\d+/.*(?<!_d)\.so$}
        || $item->name
        =~ m{^ usr/lib/python3(?:[.]\d+)? / \S+ [.]cpython- \d+ - \S+ [.]so $}x
    )
misses libraries like /usr/lib/x86_64-linux-gnu/libboost_numpy313.so.1.83.0

Since there is already an ELF check above, I'd suggest dropping this 
filename check when updating the lintian check.
