Node.js v0.8 即將發布

Node.js是一套用來編寫高性能網絡服務器的JavaScript工具包，一系列的變化由此開始。比較獨特的是，Node.js會假設你是在POSIX環境下運行它Linux 或 Mac OS X。如果你是在Windows下，那就需要安裝MinGW以獲得一個仿POSIX的環境。在Node中，Http是首要的。Node為創建http服務器作了優化，所以你在網上看到的大部分示例和庫都是集中在web上(http框架、模板庫等）。

Node.js v0.8 版本指日可待了，0.7 版本再經過1個或者2個版本發布就轉為穩定版了。

NodeJS v0.6 和 Node.js v0.8 在 API 上有一些小變化。

廢棄:

• http.Client()
• path.{exists,existsSync} was moved to fs.{exists,existsSync}
• tty.setRawMode(mode) was moved to tty.ReadStream#setRawMode() (i.e. process.stdin.setRawMode())

刪除:

• waf build system - node.js will be using gyp now * If you are a native module author, migrate to node-gyp ASAP!
• sys throws

改動:

• process * process.stdin.on('keypress') will not be emitted by default, as it’s an internal API.

• cluster

  • cluster.fork() no longer return a child_process.fork() object use cluster.fork().process to get the object.
  • the 'death' event on the cluster object is renamed to 'exit'.
  • the kill() method is renamed to destroy().
  • the CLUSTER_WORKER_ID env is now called CLUSTER_UNIQUE_ID, but you should not have used that anyway.
  • workers do now kill them self when they accidentally losses there connection with the master.
  </li>

• http

  • http.Server emits 'connect' event instead of 'upgrade' when the CONNECT method is requested.
  • http.ServerResponse sends Date: header by default. You can disable it by setting response.sendDate to false.
  • http.ClientRequest emits 'connect' event instead of 'request' when the CONNECT method is responded.
  </ul> </li>

  • child_process

    • arguments and options arguments of child_process.fork() became an option.
    • the ‘exit’ event is now emitted right after the child process exits. It no longer waits for all stdio pipes to be closed.
    • the ‘close’ event was added that has is emitted after the child has exited and all the stdio pipes are closed.
    </ul> </li>

    • readline * arguments of rl.createInterface became an option as rl.createInterface(options) but still took an old style as rl.createInterface(input, output, completer)

    • url * url.parse() now parses IPv6 addresses.

    • fs * path.exists() and path.existsSync() has moved to fs.exists() and fs.existsSync().

    • console * console.timeEnd now throws when there’s no such label

    </ul>

    添加:

    • buffer * 'utf16le' encoding.

    • child_process

      • silent option to child_process.fork() - stdout and stderr won’t be shared with parent.
      • .disconnect() when using child_process.fork() this will allow the child to die graceful.
      </li>

    • cluster

      • 'fork', 'online', 'listening', and 'setup' events.
      • Worker object which is provided from cluster.workers (in the master) or cluster.worker (in the worker).
      • env optional argument to cluster.fork().
      • cluster.setupMaster() and cluster.settings.
      • cluster.disconnect() and worker.disconnect().
      • worker.uniqueID what there before was internally known as workerID.
      • worker.suicide flag set when worker disconnect or die, indicate if this was an accidental death.
      </ul> </li>

      • crypto

        • crypto.getDiffieHellman().
        • cipher.setAutoPadding() and decipher.setAutoPadding().
        • ciphers option to crypto.createCredentials().
        </ul> </li>

        • domain * see http://nodejs.org/docs/v0.7.9/api/domain.html

        • fs

          • fs.appendFile() and fs.appendFileSync().
          • wx, wx+, ax, and ax+ modes to fs.open() and fs.openSync().
          </ul> </li>

          • http

            • callback optional argument to server.close().
            • sendDate property to http.ServerResponse.
            </ul> </li>

            • https * ciphers, rejectUnauthorized option to https.request() and https.get().

            • net

              • net.connect(options, [connectionListener).
              • callback optional argument to server.close().
              </ul> </li>

              • process

                • process.abort().
                • process.hrtime(), hi-res timer with up to nanosecond granularity.
                </ul> </li>

                • querystring * querystring.parse(str, [sep], [eq], [options]).

                • stream * 'utf16le' and 'ucs2' encoding to setEncoding().

                • tls

                  • tls.CLIENT_RENEG_LIMIT and tls.CLIENT_RENEG_WINDOW to mitigate session renegotiation attacks
                  • tls.connect(options, [secureConnectionListener]).
                  • ciphers, rejectUnauthorized and socket options to tls.connect().
                  • cleartextStream.getCipher() was added in the api doc and open to the public.
                  </ul> </li>
