HipHop在C可执行文件中编译PHP。 PHP错误会发生什么?

难以调试吗?

编辑:我查看了文档,但没有找到任何内容

我做了几次快速测试(没有时间和我喜欢的hiphop一样,不幸的是;-();这是我得到的结果:< / p>



首先,这里是test-2.php的内容,其中包含一个解析错误:

<?php

echo "what with a parse error ?

注意:字符串未完成


试着用PHP运行它,我得到:

$ php test-2.php 
PHP Parse error:  syntax error, unexpected $end, expecting T_VARIABLE or T_DOLLAR_OPEN_CURLY_BRACES or T_CURLY_OPEN in /home/squale/temp/hiphop-php/tests/test-2.php on line 5

Parse error: syntax error, unexpected $end, expecting T_VARIABLE or T_DOLLAR_OPEN_CURLY_BRACES or T_CURLY_OPEN in /home/squale/temp/hiphop-php/tests/test-2.php on line 5


试着用hiphop编译,我得到:

$ /home/squale/temp/hiphop-php/hiphop-php/src/hphp/hphp test-2.php --keep-tempdir=1 --log=3
running hphp...
creating temporary directory /tmp/hphp_JdsWcU ...
parsing inputs...
parsing ./test-2.php...
parsing inputs took 0'00" (0 ms) wall time
running hphp took 0'00" (154 ms) wall time
Exception: Unable to parse file: ./test-2.php
 (Line: 5, Char: 0): syntax error, unexpected $end

即。具有解析错误的文件无法编译 - 这是有道理的。

错误消息包含PHP错误消息中的一些信息 - 但不完全一样......

这意味着在尝试使用hiphop编译应用程序之前,您可能想尝试使用PHP:PHP提供的错误消息更具描述性。



现在,让我们尝试一些运行时错误/警告;这是test-1.php的内容:

<?php                                                                                                                                                                                                                                                                          

error_reporting(E_ALL);                                                                                                                                                                                                                                                        
ini_set('display_errors', 'On');                                                                                                                                                                                                                                               

if ($_GET['test'] == '1') {                                                                                                                                                                                                                                                    
        $data = (object)array(10);                                                                                                                                                                                                                                             
        echo $data[0];                                                                                                                                                                                                                                                         
} else if ($_GET['test'] == '2') {                                                                                                                                                                                                                                             
        echo 10/0;                                                                                                                                                                                                                                                             
} else if ($_GET['test'] == '3') {                                                                                                                                                                                                                                             
        file_put_contents('/bin/non-allowed', 'hello !');                                                                                                                                                                                                                      
}

echo "plop\n";

尝试从Apache + PHP运行该文件,您会收到三个错误:
(我将文件复制到我的文档根目录 - 这意味着Apache的错误路径不一样)

首先,我得到http://localhost/temp/test-1.php?test=1

Fatal error: Cannot use object of type stdClass as array in /home/squale/developpement/tests/temp/test-1.php on line 8

然后,尝试http://localhost/temp/test-1.php?test=2我得到:

Warning: Division by zero in /home/squale/developpement/tests/temp/test-1.php on line 10
plop 

最后,凭http://localhost/temp/test-1.php?test=3,我得到:

Warning: file_put_contents(/bin/non-allowed) [function.file-put-contents]: failed to open stream: Permission denied in /home/squale/developpement/tests/temp/test-1.php on line 12
plop


现在,使用hiphop编译test-1.php文件并在Web服务器模式下运行它,我在编译阶段得到了这个,这意味着它没问题:

$ /home/squale/temp/hiphop-php/hiphop-php/src/hphp/hphp test-1.php --keep-tempdir=1 --log=3
running hphp...

然后,启动服务器:

$ /tmp/hphp_xXZ8US/program -m server -p 8080
Could not mlockall

loading static content took 0'00" (0 ms) wall time

现在,让我们尝试访问这三个网址;首先,我得到http://localhost:8080/test-1.php?test=1

  • 浏览器中没有任何内容
  • Unhandled error: Invalid operand type was used: not ArrayAccess objects.在我启动服务器的控制台中

对于http://localhost:8080/test-1.php?test=2,我得到:

  • 在浏览器中:plop
  • 在我启动浏览器的控制台中:Division by zero

最后,对于http://localhost:8080/test-1.php?test=3,我得到:

  • 在浏览器中:plop
  • 在控制台中: nothing

在这里,错误的迹象也不如PHP那么好......至少在默认选项中......



从hiphop的Runtime options wiki page判断,您可以指定包含一些选项的配置文件。
这是我使用的config.txt的内容:

Log {
    Level = Verbose
    NoSilencer = true
    AlwaysLogUnhandledExceptions = true
    RuntimeErrorReportingLevel = 6143
    Header = false
    InjectedStackTrace = true
    NativeStackTrace = true
    MaxMessagesPerRequest = -1
}

ErrorHandling {
    CallUserHandlerOnFatals = true
    NoInfiniteLoopDetection = false
    NoInfiniteRecursionDetection = false
    MaxStackDepth = 1000
    ThrowBadTypeExceptions = true
    ThrowNotices = true
    NoticeFrequency = 1    # 1 out of these many notices to log
    WarningFrequency = 1   # 1 out of these many warnings to log
    AssertActive = false
    AssertWarning = false
  }


重新启动服务器,使用--config开关指向该文件:

$ /tmp/hphp_xXZ8US/program -m server -p 8080 --config=config.txt
Could not mlockall
loading static content...
loading static content took 0'00" (0 ms) wall time
page server started
admin server started
all servers started

我应该获得更多信息......让我们再试一次这三个请求。


首先,我得到http://localhost:8080/test-1.php?test=1

  • 与之前相同

对于http://localhost:8080/test-1.php?test=2,我得到:

  • 与之前相同

最后,对于http://localhost:8080/test-1.php?test=3,我得到:

  • 在浏览器中:plop
  • 在控制台中:我之前未收到的新错误消息:f_file_put_contents/316: Permission denied


我没有尝试更多,但使用该配置文件和--config开关看起来是一个有趣的想法; - )



注意:我在Ubuntu 9.10 64位上进行了这些测试 - 这是一个官方支持的系统;安装非常简单。

这意味着您可以尝试这些,在虚拟机中进行安装,例如:只要您对Linux和编译软件有所了解,安装hiphop就不是一项不可能完成的任务。
