2010-04-01runtime: correct memory leak in selectRuss Cox1-0/+48
* adds pass 3 to dequeue from channels eagerly various other cleanup/churn: * use switch on cas->send in each pass to factor out common code. * longer goto labels, commented at target * be more agressive about can't happen: throw instead of print + cope. * use "select" instead of "selectgo" in errors * use printf for debug prints when possible R=ken2, ken3 CC=golang-dev, r http://codereview.appspot.com/875041

note that sortmain.go has been run through hg gofmt; only the formatting of the day initializers changed. i'm happy to revert that formatting if you'd prefer. stop on error in doc/progs/run R=r CC=golang-dev http://codereview.appspot.com/850041

2009-12-18runtime: fix race conditionAdam Langley1-0/+83
(Thanks to ken and rsc for pointing this out) rsc: ken pointed out that there's a race in the new one-lock-per-channel code. the issue is that if one goroutine has gone to sleep doing select { case <-c1: case <-c2: } and then two more goroutines try to send on c1 and c2 simultaneously, the way that the code makes sure only one wins is the selgen field manipulation in dequeue: // if sgp is stale, ignore it if(sgp->selgen != sgp->g->selgen) { //prints("INVALID PSEUDOG POINTER\n"); freesg(c, sgp); goto loop; } // invalidate any others sgp->g->selgen++; but because the global lock is gone both goroutines will be fiddling with sgp->g->selgen at the same time. This results in a 7% slowdown in the single threaded case for a ping-pong microbenchmark. Since the cas predominantly succeeds, adding a simple check first didn't make any difference.
