It also includes the low-level type information +used by the reflect package; see reflect's documentation for the programmable +interface to the run-time type system. + +Environment Variables + +The following environment variables ($name or %name%, depending on the host +operating system) control the run-time behavior of Go programs. The meanings +and use may change from release to release. + +The GOGC variable sets the initial garbage collection target percentage. +A collection is triggered when the ratio of freshly allocated data to live data +remaining after the previous collection reaches this percentage. The default +is GOGC=100. Setting GOGC=off disables the garbage collector entirely. +The runtime/debug package's SetGCPercent function allows changing this +percentage at run time. See http://golang.org/pkg/runtime/debug/#SetGCPercent. + +The GOGCTRACE variable controls debug output from the garbage collector. +Setting GOGCTRACE=1 causes the garbage collector to emit a single line to standard +error at each collection, summarizing the amount of memory collected and the +length of the pause. Setting GOGCTRACE=2 emits the same summary but also +repeats each collection. + +The GOMAXPROCS variable limits the number of operating system threads that +can execute user-level Go code simultaneously. There is no limit to the number of threads +that can be blocked in system calls on behalf of Go code; those do not count against +the GOMAXPROCS limit. This package's GOMAXPROCS function queries and changes +the limit. + +The GOTRACEBACK variable controls the amount of output generated when a Go +program fails due to an unrecovered panic or an unexpected runtime condition. +By default, a failure prints a stack trace for every extant goroutine, eliding functions +internal to the run-time system, and then exits with exit code 2. +If GOTRACEBACK=0, the per-goroutine stack traces are omitted entirely. +If GOTRACEBACK=1, the default behavior is used. +If GOTRACEBACK=2, the per-goroutine stack traces include run-time functions. +If GOTRACEBACK=crash, the per-goroutine stack traces include run-time functions, +and if possible the program crashes in an operating-specific manner instead of +exiting. For example, on Unix systems, the program raises SIGABRT to trigger a +core dump. + +The GOARCH, GOOS, GOPATH, and GOROOT environment variables complete +the set of Go environment variables. They influence the building of Go programs +(see http://golang.org/cmd/go and http://golang.org/pkg/go/build). +GOARCH, GOOS, and GOROOT are recorded at compile time and made available by +constants or functions in this package, but they do not influence the execution +of the run-time system. */ package runtime diff --git a/src/pkg/runtime/futex_test.go b/src/pkg/runtime/futex_test.go new file mode 100644 index 000000000..51f4d0f12 --- /dev/null +++ b/src/pkg/runtime/futex_test.go @@ -0,0 +1,31 @@ +// Copyright 2013 The Go Authors.
