2010-05-06Save the scheduling state even predawn.Ian Lance Taylor1-4/+4

R=r http://codereview.appspot.com/156059
2009-11-17runtime: do not create new threads during malloc.Russ Cox1-2/+5
the signal handling stack is a different size than the normal stack, so it cannot be allocated using the backup stack allocator. Fixes issue 250. R=agl1 CC=golang-dev http://codereview.appspot.com/157044
2009-11-10update old comment: things are much better nowRuss Cox1-5/+6
R=r http://codereview.appspot.com/152057
2009-10-15rename sys functions to runtime,Russ Cox1-7/+7
because they are in package runtime. another step to enforcing package boundaries. R=r DELTA=732 (114 added, 93 deleted, 525 changed) OCL=35811 CL=35824
2009-10-12stack overflow debugging and fix.Russ Cox1-10/+1
* in 6l, -K already meant check for stack underflow. add -KK to mean double-check stack overflows even in nosplit functions. * comment out print locks; they deadlock too easily but are still useful to put back for special occasions. * let runcgo assembly switch to scheduler stack without involving scheduler directly. because runcgo gets called from matchmg, it is too hard to keep it from being called on other stacks. R=r DELTA=94 (65 added, 18 deleted, 11 changed) OCL=35591 CL=35604
2009-10-09keep a list of all the M's,Russ Cox1-1/+6
so that the garbage collector doesn't free them. R=ken OCL=35538 CL=35538
2009-10-038c, 8l dynamic loading support.Russ Cox1-4/+41
better mach binaries. cgo working on darwin+linux amd64+386. eliminated context switches - pi is 30x faster. add libcgo to build. on snow leopard: - non-cgo binaries work; all tests pass. - cgo binaries work on amd64 but not 386. R=r DELTA=2031 (1316 added, 626 deleted, 89 changed) OCL=35264 CL=35304
2009-09-18Rudimentary command shell for Ogle. Hack to prevent linkerAustin Clements1-0/+6

2009-07-21runtime: fix init scheduling bug.Russ Cox1-0/+8
if there is a goroutine waiting to run and the init goroutine enters a system call, entersyscall was trying to kick off a new scheduler for the other goroutine, causing a panic (new goroutines can't run until main.main). R=r DELTA=32 (32 added, 0 deleted, 0 changed) OCL=31982 CL=31982
