2009-12-18runtime: fix race conditionAdam Langley2-0/+86
(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.

2009-12-151) Change default gofmt default settings forRobert Griesemer15-558/+558
parsing and printing to new syntax. Use -oldparser to parse the old syntax, use -oldprinter to print the old syntax. 2) Change default gofmt formatting settings to use tabs for indentation only and to use spaces for alignment. This will make the code alignment insensitive to an editor's tabwidth. Use -spaces=false to use tabs for alignment. 3) Manually changed src/exp/parser/parser_test.go so that it doesn't try to parse the parser's source files using the old syntax (they have new syntax now). 4) gofmt -w src misc test/bench 5th and last set of files.

2009-12-11Remove GOBIN in PATH dependency; don't assume cwd is $GOROOT/srcDevon H. O'Dell1-2/+5
This change removes the necessity to have GOBIN in $PATH, and also doesn't assume that the build is being run from $GOROOT/src. This is a minimal set of necessary changes to get Go to build happily from the FreeBSD ports collection. R=rsc CC=golang-dev http://codereview.appspot.com/171044 Committer: Russ Cox <rsc@golang.org>

2009-11-23go: makes it build for the case $GOROOT has whitespacesSergio Luis O. B. Correia1-1/+1
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.
