ckolivas fd7b21ed56 Use a pthread conditional that is broadcast whenever work restarts are required. Create a generic wait function waiting a specified time on that conditional that returns if the condition is met or a specified time passed to it has elapsed. Use this to do smarter polling in bitforce to abort work, queue more work, and check for results to minimise time spent working needlessly.

ckolivas 21a23a45d7 Work around pools that advertise very low expire= time inappropriately as this leads to many false positives for stale shares detected.

ckolivas b198423d17 Don't keep rolling work right up to the expire= cut off. Use 2/3 of the time between the scantime and the expiry as cutoff for reusing work.

Con Kolivas 17ba2dca63 Logic fail on queueing multiple requests at once. Just queue one at a time.
13 years ago
Con Kolivas 42ea29ca4e Use a queueing bool set under control_lock to prevent multiple calls to queue_request racing.

Con Kolivas 63dd598e2a Queue multiple requests at once when levels are low.
13 years ago
Con Kolivas 757922e4ce Use the work clone flag to determine if we should subtract it from the total queued variable and provide a subtract queued function to prevent looping over locked code.

Con Kolivas 32f5272123 Revert "With better bounds on the amount of work cloned, there is no need to age work and ageing it was picking off master work items that could be further rolled."

Con Kolivas 74cd6548a9 Use a static base measurement difference of how many items to clone since requests_staged may not climb while rolling.

Con Kolivas 411784a99d As work is sorted by age, we can discard the oldest work at regular intervals to keep only 1 of the newest work items per mining thread.
