[Yum-devel] [PATCH 2/2] Avoid creating countless transaction sets just to read packages

[Panu Matilainen]

Use the transaction handle we already have in populateTs() for fetching
headers from packages. Flipping bits for signature checking is
much cheaper and saner than instanciating and destroying entire
transaction sets once per every single package to be installed.

Alternatively an optional ts argument could be added to
po.returnHeaderFromPackage() if that's preferred.
