Functions ¶
func CloseMemMappedFile ¶
CloseMemMappedFile destroys memory mapping created by CreateMemMappedFile.
func CopyFile ¶
CopyFile atomically copies oldFile to newFile preserving permissions and modification time.
func CopyFiles ¶
CopyFiles copies files from srcDir to dstDir as atomically as possible. Files are assumed to be relative names in slash notation. All other files in dstDir are removed.
func CreateMemMappedFile ¶
CreateMemMappedFile creates a temp file with the requested size and maps it into memory.
func FilesExist ¶
FilesExist returns true if all files exist in dir. Files are assumed to be relative names in slash notation.
func HandleInterrupts ¶
func HandleInterrupts(shutdown chan struct{})
HandleInterrupts closes shutdown chan on first SIGINT (expecting that the program will gracefully shutdown and exit) and terminates the process on third SIGINT.
func IsAccessible ¶
IsAccessible checks if the file can be opened.
func LinkFiles ¶
LinkFiles creates hard links for files from dstDir to srcDir. Files are assumed to be relative names in slash notation. All other files in dstDir are removed.
func LongPipe ¶
func LongPipe() (io.ReadCloser, io.WriteCloser, error)
func PrependContext ¶
func ProcessExitStatus ¶
func ProcessExitStatus(ps *os.ProcessState) int
ProcessExitStatus returns process exit status. This is here only because of fuchsia that does not implement WaitStatus.
func ProcessTempDir ¶
ProcessTempDir creates a new temp dir in where and returns its path and an unique index. It also cleans up old, unused temp dirs after dead processes.
func Run ¶
Run runs cmd with the specified timeout. Returns combined output. If the command fails, err includes output.
func SandboxChown ¶
func TempFile ¶
TempFile creates a unique temp filename. Note: the file already exists when the function returns.
func WriteExecFile ¶
func WriteTempFile ¶
WriteTempFile writes data to a temp file and returns its name.
Types ¶
type VerboseError ¶
func (*VerboseError) Error ¶
func (err *VerboseError) Error() string
