2009-12-08runtime: start new darwin/amd64 threads on correct stack,Russ Cox1-11/+13

2009-12-08Fix stack on FreeBSD / add stack check across the boardDevon H. O'Dell8-10/+36
FreeBSD was passing stk as the new thread's stack base, while stk is the top of the stack in go. The added check should cause a trap if this ever comes up in any new ports, or regresses in current ones. R=rsc CC=golang-dev http://codereview.appspot.com/167055 Committer: Russ Cox <rsc@golang.org>

2009-12-07runtime: don't touch pages of memory unnecessarily.Russ Cox8-45/+15
cuts working size for hello world from 6 MB to 1.2 MB. still some work to be done, but diminishing returns. R=r http://codereview.appspot.com/165080
2009-12-07runtime: introduce unsafe.New and unsafe.NewArrayRuss Cox2-4/+42

2009-12-07pick off special one-byte case in copy. worth 2x in benchmarks (38ns->16ns).Rob Pike1-1/+5
the one-item case could be generalized easily with no cost. worth considering. R=rsc CC=golang-dev, cw http://codereview.appspot.com/167044

2009-12-04runtime: shift the index for the sort by one.Adam Langley1-6/+2
Makes the code look cleaner, even if it's a little harder to figure out from the sort invariants. R=rsc CC=golang-dev http://codereview.appspot.com/165061
2009-12-04Remove global chanlock.Adam Langley1-33/+75
On a microbenchmark that ping-pongs on lots of channels, this makes the multithreaded case about 20% faster and the uniprocessor case about 1% slower. (Due to cache effects, I expect.) R=rsc, agl CC=golang-dev http://codereview.appspot.com/166043

2009-11-23go: makes it build for the case $GOROOT has whitespacesSergio Luis O. B. Correia1-2/+2
the bash scripts and makefiles for building go didn't take into account the fact $GOROOT / $GOBIN could both be directories containing whitespaces, and was not possible to build it in such a situation. this commit adjusts the various makefiles/scripts to make it aware of that possibility, and now it builds successfully when using a path with whitespaces as well.

2009-11-18Add an intptr type to runtime; needed in FreeBSDDevon H. O'Dell2-1/+3
In thread.c, we need to cast to whatever the native size of intptr is on the system, but we only have uintptr available. They're the same size, but can't do signed casts without this one :). R=rsc CC=golang-dev http://codereview.appspot.com/156073 Committer: Russ Cox <rsc@golang.org>

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

2009-11-17FreeBSD-specific porting work.Devon H. O'Dell11-3/+690
cgo/libmach remain unimplemented. However, compilers, runtime, and packages are 100%. I still need to go through and implement missing syscalls (at least make sure they're all listed), but for all shipped functionality, this is done.

2009-11-13runtime: warn about SELinux based mmap failures on Linux.Adam Langley5-5/+32
SELinux will cause mmap to fail when we request w+x memory unless the user has configured their policies. We have a warning in make.bash, but it's quite likely that the policy will be reset at some point and then all their binaries start failing. This patch prints a warning on Linux when mmap fails with EACCES. R=rsc CC=golang-dev http://codereview.appspot.com/152086

2009-10-28Fix bug when sending via select.Adam Langley1-32/+19
selfree maintains a cache of Select structures for several sizes. In newselect, we'll use an entry from the cache if one is found. However, the Scase structures corresponding to a send may have been allocated for the wrong size. In this case we'll write off the end of the Scase into random memory and, generally, read some amount of junk in the receive. This patch fixes the issue by removing the cache, on the advice of rsc. R=rsc CC=go-dev http://go/go-review/1016002

call. This uses the header files from a 32-bit Ubuntu Hardy system. The use of _LOOSE_KERNEL_NAMES seems right. The -D__ARCH_SI_UID_T works around a bug which appears to be fixed in later Linux versions. R=rsc http://go/go-review/1013015
