android init.rc 语法分析

原文地址为： [android init.rc 语法分析][android init.rc]

此文来自于对http://source.[android][].com/porting/index.html中bring up段的简译。其中有一处与源码的

system/core/ [init][]/readme.txt（此文也是对init.rc 的解释）内容不同：

socket <name> <type> <perm> \[ <user> \[ <group> \] \]

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－

注1：另外还讲述了怎样输出log：

Debugging notes  
\---------------  
By default, programs executed by init will drop stdout and stderr into  
/dev/null. To help with debugging, you can execute your program via the  
Andoird program logwrapper. This will redirect stdout/stderr into the  
Android logging system (accessed via logcat).  
For example  
service akmd /system/bin/logwrapper /sbin/akmd

注2：讲述了一个新的命令

sysclktz <mins\_west\_of\_gmt>  
 Set the system clock base (0 if system clock ticks in GMT)

注3：triggers

boot  
 This is the first trigger that will occur when init starts  
 (after /init.conf is loaded)  
<name>=<value>  
 Triggers of this form occur when the property <name> is set  
 to the specific value <value>.  
device-added-<path>  
device-removed-<path>  
 Triggers of these forms occur when a device node is added  
 or removed.  
service-exited-<name>  
 Triggers of this form occur when the specified service exits.

init 由如下四种类型语句组成：

*  Actionn ：行为  
    
 *  Commands  
    
 *  Services
 *  Options

语法(language syntax)结构如下：

*  每一个语句占据一行，并且各个关键字被空格分开。c规范中的（如 \\n）反斜杠将被忽略(backslash escapes)而被认为是一个空格 ，双引号用来保证空格不会把一个文字串分分为多个关键字。行最后的反斜杠用作续行。  
    
 *  由 \# （前面允许有空格）开始的行都是注释行(comment)
 *  一个actions 或 services 的开始隐含声明了一个新的段，所有commands 或 options 属于最近的声明。在第一个段之前的 commands 或 options 都会被忽略
 *  每一个actions 和 services 都有不同的名字。后面与前面发生重名的，那么这个后面重名的将被忽略或被认为是一个错误

Actions

Actions其实就是一组被命名的命令序列。actions 都有一个触发条件，触发条件决定了action何时执行。当一个事件发生如果匹配action的触发条件，那么这个action将会被添加到预备执行队列的尾部（除非它已经在队列当中）

每一个action中的命令将被顺序执行。init进程负责在其它activities（如：设备创建/销毁，属性设置，进程重启）之间执行这些命令序列。

action 的格式如下

on <trigger>
      <command>
      <command>
      <command>

Services

services 是一些由init 启动 和 重新（如果有需要）启动的程序，当然这些程序如果是存在的。

services 的格式如下：

service <name> <pathname> [ <argument> ]*
      <option>
      <option>
      ...

Options

options 是service的修饰符，用来告诉init 怎样及何时启动service。

Triggers

Triggers are strings used to match certain kinds of events that cause an action to occur.

<table> 
 <tbody> 
  <tr> 
   <th>Trigger</th> 
   <th>Description</th> 
  </tr> 
  <tr> 
   <td><code>boot</code></td>

  </tr> 
  <tr> 
   <td><code>device-added-&lt;path&gt;<br> device-removed-&lt;path&gt;</code></td> 
   <td>Triggers of these forms occur when a device node is added or removed.</td>

Properties

Init updates some system properties to provide some insight into  
what it's doing:

<table> 
 <tbody> 
  <tr> 
   <th>Property</th> 
   <th>Description</th> 
  </tr> 
  <tr> 
   <td><code>init.action</code></td> 
   <td>Equal to the name of the action currently being executed or "" if none.</td> 
  </tr> 
  <tr> 
   <td><code>init.command</code></td> 
   <td>Equal to the command being executed or "" if none.</td> 
  </tr> 
  <tr> 
   <td><code>init.svc.&lt;name&gt;</code></td> 
   <td>State of a named service ("stopped", "running", or "restarting").</td> 
  </tr> 
 </tbody> 
</table>

在init.rc中使用属性的范例如下：

<table>    
 <tbody> 
  <tr> 
   <td> <p> </p> <p>setprop ro.FOREGROUND_APP_MEM 1536</p> <p>setprop ro.VISIBLE_APP_MEM 2048</p> <p>on property:ro.kernel.qemu=1</p> <p>start adbd</p> </td> 
  </tr> 
 </tbody> 
</table>

setprop用于设置属性，on property可以用于判断属性，这里的属性在整个Android系统运行中都是一致的。

init脚本中的关键字可以参考：system/core/init/keywords.h
