node 0.5.0-pre新增功能汇总

近期node社区一直在在热火朝天的完善libuv中. 新功能开发方面的似乎变动不大. 从目前的使用来看,在osx下稳定性还不错.可用度也很高 窃以为, 已经可以作为开发环境来了. btw.前几天出了个missing headers files的编译问题 这里把v0.5引入的新功能做了各简单的汇总. Buffer 二进制数值读写 buffer.readUInt8(offset, endian) buffer.readUInt16(offset, endian) buffer.readUInt32(offset, endian) buffer.readInt8(offset, endian) buffer.readInt16(offset, endian) buffer.readInt32(offset, endian) buffer.readFloat(offset, endian) buffer.readDouble(offset, endian) buffer.writeUInt8(value, offset, endian) buffer.writeUInt16(value, offset, endian) buffer.writeUInt32(value, offset, endian) buffer.writeInt8(value, offset, endian) buffer.writeInt16(value, offset, endian) buffer.writeInt32(value, offset, endian) buffer.writeFloat(value, offset, endian) buffer.writeDouble(value, offset, endian) buffer填充 buffer.fill(value, offset=0, length=-1) Child Process child_process.fork 主进程与子进程简单通信 // master.js var cp = require('child_process'); var n = cp.fork(__dirname + '/child.js'); n.on('message', function(m) { console.log('PARENT got message:', m); }); n.send({ hello: 'world' }); // child.js process.on('message', function(m) { console.log('CHILD got message:', m); }); process.send({ foo: 'bar' }); File System chown支持 fs.chown(path, mode, [callback]) fs.chownSync(path, mode) fs.fchown(path, mode, [callback]) fs.fchownSync(path, mode) fs.lchown(path, mode, [callback]) fs.lchownSync(path, mode) timestamp修改 fs.utimes(path, atime, mtime, callback) fs.utimesSync(path, atime, mtime) fs.futimes(path, atime, mtime, callback) fs.futimesSync(path, atime, mtime) fsync支持 fs.fsync(fd, callback) fs.fsyncSync(fd) file.writeStream file.bytesWritten Http http.request与http.getAgent支持unix domain socket OS os.platform() os.arch() os.release() os.getNetworkInterfaces() process process.arch process.uptime() 其他 新增对module cache的访问 require.cache 新增对主module的访问 require.main 新增异步模快定义的支持 define(function (require, exports, module) { var PI = Math.PI; exports.area = function (r) { return PI * r * r; }; exports.circumference = function (r) { return 2 * PI * r; }; });
