示例1: isFileWriteable
func isFileWriteable(p gopath.GoPath) bool {
if p.IsExists() {
var closer, err = os.OpenFile(p.Path(), os.O_WRONLY, 0)
if closer != nil {
closer.Close()
}
return err == nil
}
return isDirWriteable(p.Dir())
}示例2: NewFilesystemLoader
// NewFilesystemLoader creates a new instance with templates located in the
// given root path.
func NewFilesystemLoader(root gopath.GoPath) *FilesystemLoader {
if root.HasErr() {
panic(fmt.Sprintf("NewFilesystemLoader: root has error: %s", root.Err()))
}
if !root.IsExists() {
panic(fmt.Sprintf("NewFilesystemLoader: root %s does not exist", root.Path()))
}
watcher, err := fsnotify.NewWatcher()
if err != nil {
panic(fmt.Sprintf("NewFilesystemLoader: can't open watcher: %s", err))
}
var loader = &FilesystemLoader{
root,
watcher,
make(map[string]chan *template.Template),

go loader.processEvents()
return loader
}示例3: assertPathValidForWriteAccess
// assertPathValidForWriteAccess sets the error flag when the path may not be
// opened for writing by this process.
func (i *pathIO) assertPathValidForWriteAccess(p gopath.GoPath) {
if i.hasErr() {
return
}
if p.HasErr() {
i.setErr(p.Err())
return
}
if p.IsExists() {
if !p.IsRegular() || !isPathWriteable(p) {
i.setErr(store.NewAccessDeniedError(fmt.Sprintf(
"path '%s' with mode %s denotes no regular file or no writeable directory",
