[Yum-devel] [PATCH] searchPackageProvides(): don't convert search strings to unicode

[Mike Bonnet]

The searchPackageProvides() method is converting the search strs to unicode, which causes any comparisons against utf-8-encoded values returned by sqlite to fail.  Call to_utf() instead to ensure that the values are strs, but in the cases I tested this was a noop.

Testcase:

without the patch:

$ repoquery --repofrompath=f11,http://download.bos.redhat.com/pub/fedora/linux/releases/11/Everything/x86_64/os/ --whatprovides 'font(эвристика)'
Added f11 repo from http:/download.bos.redhat.com/pub/fedora/linux/releases/11/Everything/x86_64/os
/usr/lib/python2.5/site-packages/yum/packages.py:397: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
  if reqn == n:

(and no results)

with the patch:

$ repoquery --repofrompath=f11,http://download.bos.redhat.com/pub/fedora/linux/releases/11/Everything/x86_64/os/ --whatprovides 'font(эвристика)'
Added f11 repo from http:/download.bos.redhat.com/pub/fedora/linux/releases/11/Everything/x86_64/os
