[英]With HipHop for PHP, what happens with PHP errors
HipHop在C可執行文件中編譯PHP。 PHP錯誤會發生什么?
調試難嗎?
編輯:我查看了文檔但沒有找到任何內容
我做了幾個快速測試(沒有時間和我喜歡的hiphop一樣,不幸的是;-() ;這是我得到的結果:
首先,這是test-2.php
的內容,其中包含一個解析錯誤:
<?php
echo "what with a parse error ?
注意:字符串未完成
試着用PHP運行它,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
試着用hiphop編譯,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 $end
即具有解析錯誤的文件無法編譯 - 這是有道理的。
錯誤消息有一些信息存在於PHP的錯誤消息中 - 但不完全一樣精確...
這意味着您可能希望在嘗試使用hiphop編譯應用程序之前嘗試使用PHP:PHP提供的錯誤消息更具描述性。
現在,讓我們嘗試一些運行時錯誤/警告; 這是test-1.php
的內容:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
if ($_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";
試圖從Apache + PHP運行該文件,你會得到三個錯誤:
(我將文件復制到我的文檔根目錄 - 這意味着Apache的錯誤路徑不一樣)
首先,調用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
並且,嘗試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,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
現在,使用hiphop編譯test-1.php
文件並在Web服務器模式下運行它,我在編譯階段得到了這個,這意味着它沒問題:
$ /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 ...

plop

running hphp took 0'40" (40054 ms) wall time
然后,啟動服務器:
$ /tmp/hphp_xXZ8US/program -m server -p 8080
Could not mlockall
loading static content...
loading static content took 0'00" (0 ms) wall time

all servers started
現在,讓我們嘗試訪問這三個網址; 首先,調用http://localhost:8080/test-1.php?test=1
我得到:
Unhandled error: Invalid operand type was used: not ArrayAccess objects.
在我啟動服務器的控制台中 對於http://localhost:8080/test-1.php?test=2
,我得到:
plop
Division by zero
最后,對於http://localhost:8080/test-1.php?test=3
,我得到:
plop
在這里,錯誤的跡象也不如PHP那么好...至少在默認選項中......
從hiphop的Runtime選項wiki頁面判斷,您可以指定包含一些選項的配置文件。
這是我使用的config.txt
的內容:
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
}
重新啟動服務器,使用--config
開關指向該文件:
$ /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
我應該獲得更多信息......讓我們再次嘗試我們的三個請求。
首先,調用http://localhost:8080/test-1.php?test=1
我得到:
對於http://localhost:8080/test-1.php?test=2
,我得到:
最后,對於http://localhost:8080/test-1.php?test=3
,我得到:
plop
f_file_put_contents/316: Permission denied
我沒有嘗試更多,但玩配置文件和--config
開關看起來像一個有趣的想法;-)
注意:我在Ubuntu 9.10 64位上進行了這些測試 - 這是一個官方支持的系統; 安裝很簡單。
這意味着您可以嘗試這些,在虛擬機中進行安裝,例如:只要您對Linux和編譯軟件有所了解,安裝hiphop就不是一項不可能完成的任務。
