Description Joe Izraelevitz 2007-06-08 17:22:47 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
Python 2.4.4

How reproducible:

Steps to Reproduce:
Here's the python code:

import rpm
ts = rpm.TransactionSet()
mi = ts.dbMatch(rpm.RPMTAG_BASENAMES,'whateverthebasenameshouldbe')#e.g. 'README'
for h in mi:
  print h[rpm.RPMTAG_NAME]

Actual results:
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

Expected results:
Should print out all package names that provide a file with the given base name

Additional info:
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
Comment 1 Joe Izraelevitz 2007-06-11 10:43:01 EDT
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:
