我的Node.js应用程序似乎有内存泄漏.我快速构建它,我的JavaScript不是太强大,所以这可能很容易.

我已经完成了一些堆转储,它是字符串object？泄漏记忆,每5分钟约1MB.我扩展了String,它实际上是String.Array？

堆栈:

#!/usr/local/bin/node

var port = 8081;

var io = require('socket.io').listen(port),
sys = require('sys'),
daemon = require('daemon'),
mysql = require('mysql-libmysqlclient');

var updateq = "SELECT 1=1";
var countq = "SELECT 2=2";

io.set('log level', 2);


process.on('uncaughtException', function(err) {
  console.log(err);
});

var connections = 0;

var conn = mysql.createConnectionSync();
dbconnect();

io.sockets.on('connection', function(client){ 
  connections++;
  client.on('disconnect', function(){ connections--;  }) 
});

process.on('exit', function () {
    console.log('Exiting');
    dbdisconnect();
});

function dbdisconnect() {
     conn.closeSync();
}

function dbconnect() {
    conn.connectSync('leet.hacker.org','user','password');
}


function update() {

我正在尝试使用android.provider.Telephony.SMS_RECEIVED来捕获传入的短信.

我构建了一个简单的应用程序,它适用于2.x,但是当我在我的4.0模拟器或设备上试用它时,它不起作用.

有任何想法吗？

每当此代码运行时,我都会收到"No Peer Certificate"错误.

SSL证书有效,从Namecheap(PositiveSSL)购买.它之前有CA crt,并且在Android浏览器中打开正常.

我正在尝试在Android上加密Java中的字符串,然后使用PHP和/或node.js对其进行解密

我已经尝试了http://www.androidsnippets.com/encrypt-decrypt-between-android-and-php,但只返回返回的十六进制字符串的前半部分.

我希望加密类型是带有128位密钥的AES(如果可能的话,更高).

加密密钥也需要是可配置的,所以我的问题可能与我填充字符串的方式有关.

Java的

String.format("%1$-" + n + "s", s)

PHP

$key = str_pad($key,16);

完整的Java代码:

    package com.giggsey.test;


    import java.security.NoSuchAlgorithmException;

    import javax.crypto.Cipher;
    import javax.crypto.NoSuchPaddingException;
    import javax.crypto.spec.IvParameterSpec;
    import javax.crypto.spec.SecretKeySpec;

    import android.util.Log;


    public class SimpleCrypto {

            private String iv = "fedcba9876543210";//Dummy iv (CHANGE IT!)
            private IvParameterSpec ivspec;
            private SecretKeySpec keyspec;
            private Cipher cipher;

            private String SecretKey = "0123456789abcdef";//Dummy secretKey (CHANGE IT!)

            public void doKey(String key)
            {
                    ivspec = new IvParameterSpec(iv.getBytes());

                    key = padRight(key,16);

                    Log.d("hi",key);

                    keyspec = new SecretKeySpec(key.getBytes(), "AES");

我有一张MySQL桌子:

ID, Col1, Col2, Col3, Col4, etc...

ID是一个primary key并且自表创建以来一直在工作.

我想要做的是删除所有其他列完全相同的所有记录.

我希望有一个PHP脚本从RabbitMQ队列中消耗(使用PECL AMQP模块),然后分叉以执行实际工作.

我有代码@ https://gist.github.com/giggsey/6666e67bb0e090eeb5f0

但是当我运行它时,我得到:
