So after installing xhprof:

- check your /etc/php.d/xhprof.ini or /etc/php.ini;

- set the xhprof.output_dircorrectly;

- make sure the folder permissions allow your webserver user to write there.

看看 php.ini 中 output_dir 的目录,对于php来讲有没有访问权限

[xhprof]

extension=/www/wdlinux/apache_php-5.5.38/lib/php/extensions/no-debug-non-zts-20121212/xhprof.so

xhprof.output_dir=/home/wwwroot/aaaaa/public_html/xhprof

White screen, when enabling xhprof-module

Hello,

My setup:
windows 7,
xampp-win32-1.8.3-4-VC11,
php 5.5.11,
xhprof dll fromhttp://windows.php.net/downloads/pecl/releases/xhprof/0.10.6/particually: php_xhprof-0.10.6-5.5-ts-vc11-x86
fresh drupal 7.28 without any contributed modules except drupals xhprof-module

I get a white screen, when I am enabling profiling with drupals xhprof-module. I get no php error messages, but "Error messages to display" are enabled in backend and I hadset "display_errors" and "display_startup_errors" to on in php.ini. All message I got from browser is "This webpage is not available". When I am clicking in chrome on the button more I got the following message:

"The connection to localhost was interrupted.
Check your Internet connection
Check any cables and reboot any routers, modems, or other network devices you may be using.
..."

I'm getting the same WSOD error when enabling XHProf on my server and site. As the original poster mentioned, no error messages, total white screen of death. Something is clearly wrong.

I am getting an Internal server error shortly after installation with the UI.

After that the xhprof module is shown as installed (and we all know it is!!!). After that nothing is working anymore which is outside of the admin/ path. If I load the frontpage -> Internal server error.

So finally how to use xhprof with drupal? It has been removed from devel and this plugin doesn't seem to work!

This is a known bug with PHP 5.5 -- it returns a segmentation fault when you enable the XHProf in Drupal which results in a blank page or something like a "err_empty_response" in Google Chrome.

Seehttps://bugs.php.net/bug.php?id=65345.

For the meanwhile to get around this bug you can change line 86 in xhprof/xhprof.module(usually in sites/all/modules or sites/all/modules/contrib) from:

xhprof_enable(XHPROF_FLAGS_CPU+XHPROF_FLAGS_MEMORY

to

xhprof_enable(XHPROF_FLAGS_CPU+XHPROF_FLAGS_MEMORY+XHPROF_FLAGS_NO_BUILTINS);

That should at least get the basic XHProf functionality up and running.

Thank you. Its definitely true - I am on PHP 5.5 (and xhprof 0.9.2) and if I enable the module via drush I also get a segmentation fault. Unfortunately setting the XHPROF_FLAGS_NO_BUILTINS didn't change anything for me. I tried

xhprof_enable(XHPROF_FLAGS_CPU+XHPROF_FLAGS_MEMORY+XHPROF_FLAGS_NO_BUILTINS);

as well as

xhprof_enable(XHPROF_FLAGS_NO_BUILTINS);

but I still get a segmentation fault. :/
