Description Ville Skyttä 2010-05-19 06:15:29 UTC
rpm-python-4.8.0-14.fc13.x86_64 on current F-13:

import rpm
for hdr in rpm.TransactionSet().dbMatch("name", "gpg-pubkey"):
    print hdr.dsFromHeader()

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
SystemError: NULL result without error in PyObject_Call

Slightly different message with rpm-python-4.4.2.3-18.el5 on CentOS 5:

Traceback (most recent call last):
  File "<stdin>", line 2, in ?
SystemError: error return without exception set

rpm-python bug?

This affects rpmlint (DocFilesCheck.py).  I wonder if I could just use hdr.dsOfHeader() instead of hdr.dsFromHeader() there, it doesn't seem to have the same problem (not to mention that even that doesn't have to be done for packages that don't have doc files...)

Comment 1 Panu Matilainen 2010-05-19 06:31:36 UTC
Sure it's an rpm-python bug, I'll look into it.

Comment 2 Panu Matilainen 2010-05-19 07:26:34 UTC
Fixed upstream now, pulling into Fedora shortly... Looking at rpm 4.4.x code, the actual rpmlint code works on Centos but breaks with the reproducer (its just the print blowing up), right?

hdr.dsOfHeader() and hds.dsFromHeader() are completly different things and can't be used interchangibly. dsOfHeader() returns basically
Provides: %{name} = %{version}-%{release}
whereas dsFromHeader() returns the actual requires/provides/obsoletes/conflicts dependencies.

Right.  Ditto on F-12 with rpm-python-4.7.2-1.fc12.x86_64.

Comment 4 Panu Matilainen 2010-05-21 13:29:35 UTC
Ack. Fixed in rawhide now.
