The Go programming language

In starttheworld() we assume that P's with local work are situated in the beginning of idle P list. However, once we start the first M, it can execute all local G's and steal G's from other P's. That breaks the assumption above. Thus starttheworld() will fail to start some P's with local work. It seems that it can not lead to very bad things, but still it's wrong and breaks other assumtions (e.g. we can have a spinning M with local work). The fix is to collect all P's with local work first, and only then start them. R=golang-dev, rsc CC=golang-dev https://golang.org/cl/10051045 |

This is the source code repository for the Go programming language. For documentation about how to install and use Go, visit http://golang.org/ or load doc/install.html in your web browser. After installing Go, you can view a nicely formatted doc/install.html by running godoc --http=:6060 and then visiting http://localhost:6060/doc/install.html. Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file. -- Binary Distribution Notes If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this README). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install.html). You should also add the Go binary directory $GOROOT/bin to your shell's path. For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile: export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin See doc/install.html for more details.
