Revision: 100217 https://trac.macports.org/changeset/100217 Author: cal@macports.org Date: 2012-12-03 16:12:26 -0800 (Mon, 03 Dec 2012) Log Message: ----------- registry: use sqlite3_busy_timeout This caps CPU usage of MacPorts processes waiting for the registry database while it is exclusively locked at about 1.5%. This could be further reduced by using a busy handler and adjusting the timeout depending on the number of calls to the busy handler.
