[英]With HipHop for PHP, what happens with PHP errors
HipHop compiles PHP in a C executable. HipHop在C可执行文件中编译PHP。 What happens with PHP errors ?
PHP错误会发生什么?
Is that harder to debug ? 调试难吗?
edit : I looked through the documentation but didn't find anything 编辑:我查看了文档但没有找到任何内容
I did a couple of quick tests (haven't have the time to play with hiphop as much as I'd like, unfortunately ;-( ) ; here are the results I got : 我做了几个快速测试(没有时间和我喜欢的hiphop一样,不幸的是;-() ;这是我得到的结果:
First of all, here's the content of test-2.php
, which contains a parse error : 首先,这是
test-2.php
的内容,其中包含一个解析错误:
<?php
echo "what with a parse error ?
Note : the string is not finished 注意:字符串未完成
Trying to run that with PHP, I get : 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
Trying to compile that with hiphop, I get : 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 $end
ie the file with the parse error doesn't compile -- which stands to reason. 即具有解析错误的文件无法编译 - 这是有道理的。
The error message has some informations that were present in the PHP's error message -- but not exactly as precise... 错误消息有一些信息存在于PHP的错误消息中 - 但不完全一样精确...
Which means you might want to try with PHP before trying to compile your application with hiphop : the error message given by PHP was more descriptive. 这意味着您可能希望在尝试使用hiphop编译应用程序之前尝试使用PHP:PHP提供的错误消息更具描述性。
Now, let's try with some runtime errors/warnings ; 现在,让我们尝试一些运行时错误/警告; here's the content of
test-1.php
: 这是
test-1.php
的内容:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
if ($_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";
Trying to run that file from Apache+PHP, you'd get three possible errors : 试图从Apache + PHP运行该文件,你会得到三个错误:
(I copied the file to my document root -- which means the paths will not be the same for the errors with Apache) (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)
First of all, calling http://localhost/temp/test-1.php?test=1
I get : 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
And, trying http://localhost/temp/test-1.php?test=2
I get : 并且,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
And, finally, with http://localhost/temp/test-1.php?test=3
, I get : 最后,使用
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
Now, compiling that test-1.php
file with hiphop and running it in web-server mode, I get this during the compilation phase, which means it is OK : 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

Now, let's try accessing those three URLs ; 现在,让我们尝试访问这三个网址; first, calling
http://localhost:8080/test-1.php?test=1
I get : 首先,调用
http://localhost:8080/test-1.php?test=1
我得到:
Unhandled error: Invalid operand type was used: not ArrayAccess objects.
in the console from which I started the server For http://localhost:8080/test-1.php?test=2
, I get : 对于
http://localhost:8080/test-1.php?test=2
,我得到:
plop
plop

And, finally, for http://localhost:8080/test-1.php?test=3
, I get : 最后,对于
http://localhost:8080/test-1.php?test=3
,我得到:
plop
plop
Here, too, indications of errors are not quite as good as with PHP... at least with default options... 在这里,错误的迹象也不如PHP那么好...至少在默认选项中......
Judging from hiphop's Runtime options wiki page , you can specify a config file that contains some options. 从hiphop的Runtime选项wiki页面判断,您可以指定包含一些选项的配置文件。
Here's the content of the config.txt
I used : 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
}
Re-starting the server, using the --config
switch to point to that file : 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

I should get more informations... let's try our three requests again. 我应该获得更多信息......让我们再次尝试我们的三个请求。
First, calling http://localhost:8080/test-1.php?test=1
I get : 首先,调用
http://localhost:8080/test-1.php?test=1
我得到:
For http://localhost:8080/test-1.php?test=2
, I get : 对于
http://localhost:8080/test-1.php?test=2
,我得到:
And, finally, for http://localhost:8080/test-1.php?test=3
, I get : 最后,对于
http://localhost:8080/test-1.php?test=3
,我得到:
plop
plop
f_file_put_contents/316: Permission denied
f_file_put_contents/316: Permission denied
I didn't try much more, but playing with that config file and the --config
switch looks like an interesting idea ;-) 我没有尝试更多,但玩配置文件和
--config
开关看起来像一个有趣的想法;-)
Note : I did those tests on Ubuntu 9.10 64bits -- which is an officially supported system ; 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; installation was quite easy.
安装很简单。
Which means you could try those, doing an install in a Virtual Machine, for example : as long as you know a bit about Linux and compiling software, installing hiphop is not an impossible task. 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。
