The Go programming language

Breaks reading from stdin in parent after exec with SysProcAttr{Setpgid: true}. package main import ( "fmt" "os" "os/exec" "syscall" ) func main() { cmd := exec.Command("true") cmd.SysProcAttr = &syscall.SysProcAttr{Setpgid: true} cmd.Run() fmt.Printf("Hit enter:") os.Stdin.Read(make([]byte, 100)) fmt.Printf("Bye\n") } In go1.3, I type enter at the prompt and the program exits. With the CL being rolled back, the program wedges at the prompt. ««« original CL description syscall: SysProcAttr job control changes Making the child's process group the foreground process group and placing the child in a specific process group involves co-ordination between the parent and child that must be done post-fork but pre-exec.

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-source.html in your web browser. After installing Go, you can view a nicely formatted doc/install-source.html by running godoc --http=:6060 and then visiting http://localhost:6060/doc/install/source. 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.
