itier-client's Issues

config server support to itier client

通过配置中心获取itier机器列表，无需调用connect函数

ITier 异常信息完善

目前ITier server返回错误，无法获得errorName，很难做异常类别划分。

建议在异常返回的时候，增加一个 e: errorname 表示，或者 c 对应的code有异常类型对应列表。

2012-09-19 16:25:01.392 nodejs.ITierErrorException: ITierError: Error: Error: Cannot enqueue Query after being destroyed./host: 127.0.0.1:9999

多值查询如何传递参数？

如 WHERE id in (123,456)，如何变换成 WHERE id in (:r1, :r2), {r1: 123, r2: 456} ，还是说要调用者自己处理呢？

agent socket settings

// change Agent.defaultMaxSockets to 1000
http.Agent.defaultMaxSockets = 1000;

this may do bad effect to global settings,
why not use your own http agent?

在高压的情况下，会出现` possible EventEmitter memory leak detected`警告

(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.
Trace: 
    at Socket.<anonymous> (events.js:139:15)
    at Socket.once (events.js:160:8)
    at Socket.setTimeout (net.js:142:12)

    at ClientRequest.emit (events.js:88:20)
    at Array.0 (http.js:1273:9)
    at EventEmitter._tickCallback (node.js:192:40)

看代码是由于socket. setTimeout 导致的。

当 status() 错误的时候, 未能返回正确的错误提示

Itier.prototype.status = function (name, callback) {
  this.client.get('/status/' + name.trim(), function (error, data, code) {
    console.log(error, data.toString(), code)

=> null 'Error: No Checked OK Hosts Now' 500

itier avalibility stat and report

非正确的itier响应结构体返回定义为一次失败请求；返回结构体格式正确，但结构体中声明这是一个“失败请求”的，不纳入统计范围

spawn child process error

I found a itier client uncaughtException throw out:

timers.js:96
            if (!process.listeners('uncaughtException').length) throw e;
                                                                      ^

add no avaible host list Error

当所有节点都不可用的时候，增加特殊的错误信息返回。
