2008-12-05add support for ref counts to memory allocator.Russ Cox
mark and sweep, stop the world garbage collector (intermediate step in the way to ref counting). can run pretty with an explicit gc after each file. R=r DELTA=502 (346 added, 143 deleted, 13 changed) OCL=20630 CL=20635
2008-12-04add stub routines stackalloc() and stackfree().Russ Cox
run oldstack on g0's stack, just like newstack does, so that oldstack can free the old stack. R=r DELTA=53 (44 added, 0 deleted, 9 changed) OCL=20404 CL=20433
2008-12-03preparation for exec.Russ Cox
* syscall: add syscall.RawSyscall, which doesn't use sys.entersyscall/sys.exitsyscall add syscall.dup2 add syscall.BytePtrPtr add syscall.Rusage, RusagePtr add syscall.F_GETFD, F_SETFD, FD_CLOEXEC * runtime: clean up, correct signal handling. can now survive (continue running after) a signal. R=r DELTA=394 (286 added, 51 deleted, 57 changed) OCL=20351 CL=20369
2008-11-25change meaning of $GOMAXPROCS to number of cpus to use,Russ Cox
not number of threads. can still starve all the other threads, but only by looping, not by waiting in a system call. fix darwin syscall.Syscall6 bug. fix chanclient bug. delete $GOMAXPROCS from network tests. add stripped down printf, sys.printhex to runtime.

2008-08-05* comment, clean up schedulerRuss Cox
* rewrite lock implementation to be correct (tip: never assume that an algorithm you found in a linux man page is correct.) * delete unneeded void* arg from clone fn * replace Rendez with Note * comment mal better * use 6c -w, fix warnings * mark all assembly functions 7 R=r DELTA=828 (338 added, 221 deleted, 269 changed) OCL=13884 CL=13886
2008-08-04first cut at multithreading. works on Linux.Russ Cox
* kick off new os procs (machs) as needed * add sys·sleep for testing * add Lock, Rendez * properly lock mal, sys·newproc, scheduler * linux syscall arg #4 is in R10, not CX * chans are not multithread-safe yet * multithreading disabled by default; set $gomaxprocs=2 (or 1000) to turn it on This should build on OS X but may not.
