Description Ales Kozumplik 2013-08-14 14:36:36 UTC

Description of problem:

Librepo does not release the thread lock [1] when the IO-intensive handle.perform() is executing. This completely stalls other Python threads for the time perform() is running, causing UI freezes in threaded UI-intensive apps such as Anaconda.
