2014-09-08build: move package sources from src/pkg to srcRuss Cox
Preparation was in CL 134570043. This CL contains only the effect of 'hg mv src/pkg/* src'. For more about the move, see golang.org/s/go14nopkg.
2014-09-04runtime: correct various Go -> C function callsRuss Cox
Some things get converted. Other things (too complex or too many C deps) get onM calls. Other things (too simple) get #pragma textflag NOSPLIT. After this CL, the offending function list is basically: - panic.c - netpoll.goc - mem*.c - race stuff - readgstatus - entersyscall/exitsyscall LGTM=r, iant R=golang-codereviews, r, iant CC=dvyukov, golang-codereviews, khr https://golang.org/cl/140930043

2014-09-01runtime: convert mprof.goc to mprof.goRuss Cox
The exported Go definitions appearing in mprof.go are copied verbatim from debug.go. The unexported Go funcs and types are new. The C Bucket type used a union and was not a line-for-line translation.

2012-10-06pprof: add goroutine blocking profilingDmitriy Vyukov
The profiler collects goroutine blocking information similar to Google Perf Tools. You may see an example of the profile (converted to svg) attached to http://code.google.com/p/go/issues/detail?id=3946 The public API changes are: +pkg runtime, func BlockProfile([]BlockProfileRecord) (int, bool) +pkg runtime, func SetBlockProfileRate(int) +pkg runtime, method (*BlockProfileRecord) Stack() []uintptr +pkg runtime, type BlockProfileRecord struct +pkg runtime, type BlockProfileRecord struct, Count int64 +pkg runtime, type BlockProfileRecord struct, Cycles int64 +pkg runtime, type BlockProfileRecord struct, embedded StackRecord R=rsc, dave, minux.ma, r CC=gobot, golang-dev, r, remyoudompheng https://golang.org/cl/6443115

2012-02-08runtime, pprof: add profiling of thread creationRuss Cox
Same idea as heap profile: how did each thread get created? Low memory (256 bytes per OS thread), high reward for programs that suddenly have many threads running. Fixes #1477. R=golang-dev, r, dvyukov CC=golang-dev https://golang.org/cl/5639059

2011-10-27runtime: lock the main goroutine to the main OS thread during initRuss Cox
We only guarantee that the main goroutine runs on the main OS thread for initialization. Programs that wish to preserve that property for main.main can call runtime.LockOSThread. This is what programs used to do before we unleashed goroutines during init, so it is both a simple fix and keeps existing programs working.

2011-02-02runtime: faster allocator, garbage collectorRuss Cox
GC is still single-threaded. Multiple threads will happen in another CL. Garbage collection pauses are typically about half as long as they were before this CL. R=brainman, iant, r CC=golang-dev https://golang.org/cl/3975046
2011-01-28runtime: simpler heap map, memory allocationRuss Cox
The old heap maps used a multilevel table, but that was overkill: there are only 1M entries on a 32-bit machine and we can arrange to use a dense address range on a 64-bit machine. The heap map is in bss. The assumption is that if we don't touch the pages they won't be mapped in. Also moved some duplicated memory allocation code out of the OS-specific files.

2010-09-07runtime: use manual stack for garbage collectionRuss Cox
Old code was using recursion to traverse object graph. New code uses an explicit stack, cutting the per-pointer footprint to two words during the recursion and avoiding the standard allocator and stack splitting code. in test/garbage: Reduces parser runtime by 2-3% Reduces Peano runtime by 40% Increases tree runtime by 4-5% R=r CC=golang-dev https://golang.org/cl/2150042
