If copying a whole folder recursively: All files under the folder and subfolders will be copyed. Optional parameter "-include" allows you to specify the file name patterns. If any file has a ".gz" extension, the content are considered gzipped already, and will be stored as is. This can save volume server's gzipped processing and allow customizable gzip compression level. The file name will strip out ".gz" and stored. For example, "jquery.js.gz" will be stored as "jquery.js". If "maxMB" is set to a positive number, files larger than it would be split into chunks and copyed separatedly. The list of file ids of those chunks would be stored in an additional chunk, and this additional chunk's file id would be returned. `, } func runCopy(cmd *Command, args []string) bool { copy.secret = security.Secret(*copy.secretKey) if len(args) <= 1 { return false } filerDestination := args[len(args)-1] fileOrDirs := args[0 : len(args)-1] filerUrl, err := url.Parse(filerDestination) if err != nil { fmt.Printf("The last argument should be a URL on filer: %v\n", err) return false } path := filerUrl.Path if !strings.HasSuffix(path, "/") { path = path + "/" } for _, fileOrDir := range fileOrDirs { if !doEachCopy(fileOrDir, filerUrl.Host, path) { return false } } return true } func doEachCopy(fileOrDir string, host string, path string) bool { f, err := os.Open(fileOrDir) if err != nil { fmt.Printf("Failed to open file %s: %v", fileOrDir, err) return false } defer f.Close() fi, err := f.Stat() if err != nil { fmt.Printf("Failed to get stat for file %s: %v", fileOrDir, err) return false } mode := fi.Mode() if mode.IsDir() { files, _ := ioutil.ReadDir(fileOrDir) for _, subFileOrDir := range files { if !doEachCopy(fileOrDir+"/"+subFileOrDir.Name(), host, path+fi.Name()+"/") { return false } } return true } // this is a regular file if *copy.include != "" { if ok, _ := filepath.Match(*copy.include, filepath.Base(fileOrDir)); !ok { return true } } parts, err := operation.NewFileParts([]string{fileOrDir}) if err != nil { fmt.Printf("Failed to read file %s: %v", fileOrDir, err) } results, err := operation.SubmitFiles(*copy.master, parts, *copy.replication, *copy.collection, "", *copy.ttl, *copy.maxMB, copy.secret) if err != nil { fmt.Printf("Failed to submit file %s: %v", fileOrDir, err) } if strings.HasSuffix(path, "/") { path = path + fi.Name() } if err = filer_operation.RegisterFile(host, path, results[0].Fid, copy.secret); err != nil { fmt.Printf("Failed to register file %s on %s: %v", fileOrDir, host, err) return false } fmt.Printf("Copy %s => http://%s%s\n", fileOrDir, host, path) return true }
