HipHop For PHP,使用HipHop for PHP,会发生什么与PHP错误

我做了几个快速测试(没有时间玩嘻哈,尽可能多,我不喜欢;-();这里是我得到的结果:

首先,这里是test-2.php的内容,其中包含一个解析错误:

echo "what with a parse error ?

注意:字符串未完成

尝试用PHP运行,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来编译,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不会被编译 – 这是理由。

错误消息中有一些信息存在于PHP的错误消息中 – 但并不完全如此…

这意味着在尝试使用hiphop编译应用程序之前,您可能需要尝试使用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;这里是test-1.php的内容:

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,您会得到三个可能的错误:

(我将文件复制到我的文档根目录 – 这意味着对于Apache的错误,路径将不一样)

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

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

而且,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,用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,用嘻哈编译test-1.php文件,并以web-server模式运行,我在编译阶段得到这个,这意味着它是OK的:

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

running hphp...

creating temporary directory /tmp/hphp_xXZ8US ...

parsing inputs...

parsing ./test-1.php...

parsing inputs took 0'00" (1 ms) wall time

pre-optimizing...

post-optimizing...

plop

all files saved in /tmp/hphp_xXZ8US ...

running hphp took 0'40" (40054 ms) wall time

然后,启动服务器:

$ /tmp/hphp_xXZ8US/program -m server -p 8080

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

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

>浏览器中没什么

>未处理的错误:使用无效的操作数类型:不是ArrayAccess对象。在我从其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

>在启动浏览器的控制台中:按零排列

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:没有

在这里,错误的迹象也不如PHP …至少有默认选项…

从hiphop的Runtime options wiki page开始,您可以指定一个包含一些选项的配置文件。

以下是我使用的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

我应该得到更多的信息.​​..让我们再次尝试我们的三个请求。

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

>与以前相同

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

>与以前相同

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:我以前没有得到的新错误消息:f_file_put_contents / 316:权限被拒绝

我没有尝试更多,但玩这个配置文件和–config开关看起来像一个有趣的想法;-)

注意:我在Ubuntu 9.10 64bits上进行了这些测试 – 这是官方支持的系统;安装很简单。

这意味着你可以尝试这些,在虚拟机中进行安装,例如:只要你知道一些关于Linux和编译软件,安装hiphop并不是一件不可能的事情。
