From: Marius Avram Date: Tue, 18 Feb 2014 14:39:24 +0000 (+0200) Subject: bb/ui: store_dependency_information optimization X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=b86fd2be40303d886fdb9ad3009355584d285acc;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git bb/ui: store_dependency_information optimization This optimization is in support of the bug #5485. The function called at the beginning of every build: store_dependency_information was taking approximately 20sec and it was delaying the arrival of events from the event queue. The change minimizes the calls to _save_a_task(), reducing the time to half.
