basic git command

git is the fast version control system

Now I am studying how to use git

• Here are the commands for common using:
  

1. Use git clone to check out sources. i.e. Download pulseaudio sources:
   

   git clone git://git.0pointer.de/pulseaudio.git
   

2. Use git status to show your working tree status
   

   git status
   

3. Use git pull to update the codes to the newest version
   

   git pull origin master
   

4. Add or edit your file
   
5. Commit your new file
   

   git add your-file
   
   git commit -m 'log'
   

6. Push your change to remote repository
   

   git push origin master
   

• Here is a sample to generate a patch
  

  git status
  
  view /home/usr/.gitconfig 
  
  git add src/pulsecore/random.c
  
  git log -v
  
  git commit -m 'core: Fix variable "has_whined" value bug'
  
  git format-patch -s -1
  
  view 0001-core-Fix-variable-has_whined-value-bug.patch
  

android gstreamer debug information can not work

在android上面做一些gstreamer的工作
尝试显示出gstreamer自己的调试信息
在android模拟器上面运行：

gst-launch-0.10 --gst-debug-level=1 audiotestsrc ! audioflingersink

结果显示：

Could not open converter from 'ASCII' to 'UTF-8'

调试发现：libiconv在android上面已经移除了

在gconvert.c g_convert()中添加了以上代码自己转换，将ASCII 转换成 UTF-8,debug 消息就可以打印出来了

//--> allen add for testing
printf("allen in gconvert.c g_convert() %s %d\n", str, len);
gsize retval;
gchar *utf;
gsize utfmax;
if (len < 0)
{
 len = strlen (str);
}
utfmax = 2 * (len + 1);
printf("utfmax: %d\n", utfmax);
utf = g_malloc (utfmax);
for (retval = 0; *str && utfmax > 1; utfmax -= 2, retval += 2)
{
 *(utf + retval/2) = *(str + retval/2);
 *(utf + retval/2 + 1) = 0;
}
if (utfmax > 0)
{
 *utf = *str;
 ++retval;
}
if (bytes_read)
 *bytes_read = len + 1;
if (bytes_written)
 *bytes_written = retval;
 printf("allen in gconvert.c g_convert() %s %d\n", utf, utfmax);
 return utf;
 //<--end

ubuntu qq for linux自动关闭的问题解决方法

ubuntu 10.04还是存在这个问题 哎

下面解决的办法：

1. 在终端输入命令代码：sudo vim /usr/bin/qq

2. 在打开的qq配置文件中，在#!bin/sh下面一行，cd /usr/share/tencent/qq/前面一行的位置插入代码：

export GDK_NATIVE_WINDOWS=true

3. 最终修改后的QQ脚本配置文件如下，保存关闭即可。

#!/bin/sh
export GDK_NATIVE_WINDOWS=true
cd /usr/share/tencent/qq/
./qq

 4. 重启QQ，qq不再自动退出和关闭了。
