bitbake/cache/runqueue.py: Move workload for recipe parsing to the child process

2011-03-01T00:34:34+00:00

Parsing the recipe in the parent before forking off the child worker can mean the parent doesn't hit the idle loop and becomes a bottleneck when lauching many short lived processes. The reason we need this in the parent is to figure out the fakeroot environmental options. To address this, add the fakeroot variables to the cache and move recipe loadData into the child task. For a poky-image-sato build this results in about a 2 minute speedup (1.8%). Signed-off-by: Richard Purdie

bitbake/runqueue: Drop PATH override. This was needed for the exec() change but not now we use fork()

runqueue: pass a copy of the RunQueueStats to events

2011-02-21T13:48:39+00:00

This avoids cases where the stats are modified after the event is fired but before it's dispatched to the UI. (Bitbake rev: 1954f182687a0bd429175dda87f05d8a94bb403a) Signed-off-by: Chris Larson Signed-off-by: Richard Purdie

bitbake/runqueue.py: Avoid starvation of events to the server

2011-01-28T10:21:41+00:00

The server UI was reading 1024 bytes, then sleeping for 0.25 seconds. Since most new LogRecord events are larger than this it leads to a build up of data which is only processed slowly, leading to a bottleneck and a slow down of all bitbake processes. Thanks to Dongxiao Xu for the great work in debugging this. A large value has been left in for the read() command just to ensure some fairness amongst process handling if a task tries to log truly huge amounts of data to the server, or goes crazy and ensures the main loop doesn't stall.
