Description Panu Matilainen 2010-05-19 10:16:07 UTC

+++ This bug was initially created as a clone of Bug #593553 +++

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...)

Sure it's an rpm-python bug, I'll look into it.

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.

Fixed in rpm-4.8.0-9.el6 now.

Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
