Problem querying using RPM Python API with tag RPMTAG_BASENAMES
Last modified: 2008-05-06 15:40:44 EDT
Description of problem:
In the RPM Python API, the function dbMatch does not work as expected for tag
RPMTAG_BASENAMES. Instead of giving an iterator to header objects that contain
the given base file, it returns an iterator to an empty list.
Version-Release number of selected component (if applicable):
RPM version 4.4.2
Steps to Reproduce:
Here's the python code:
ts = rpm.TransactionSet()
mi = ts.dbMatch(rpm.RPMTAG_BASENAMES,'whateverthebasenameshouldbe')#e.g. 'README'
for h in mi:
Prints nothing. The iterator returned by ts.dbMatch always points to
an empty list, even if there are be packages with files with this basename
Should print out all package names that provide a file with the given base name
Going the other way (from header to basenames of files) works fine, eg:
will print a list of all the base names of the files the package provides
My mistake. Apparently, querying using the RPMTAG_BASENAMES requires using the
full file path, not the basename. This is why I always got no results. While
inconsistent with the information given using header[RPMTAG_BASENAMES], there's
probably no point in changing it - the patch would hurt more than help - though
the quirk should be documented here:
