#24666 [Fbk]: random blank pages for any code on any php page

ID: 24666 Updated by: sniper@php.net Reported By: dhunter at uta dot edu Status: Feedback Bug Type: Apache related Operating System: Solaris 8 PHP Version: 4.3.2 New Comment: Oopps, made a slight mistake, run it like: # gdb httpd (gdb) run -X -DSSL Previous Comments: ------------------------------------------------------------------------ [2003-07-16 21:01:24] sniper@php.net Could you try if you can reproduce this when you run apache like this: # gdb httpd -X (if you need SSL, add -DSSL there) You should test the snapshot on separate instance/machine. e.g. have another apache with PHP build from the snapshot running in other port. (separate development server would be best choice though :) ------------------------------------------------------------------------ [2003-07-16 15:56:42] dhunter at uta dot edu Thanks, I'll try the latest snapshot. I'll also try to cut down the configuration, but we use most of the options. Answers to your questions: - output buffering is on - i'm using the php.ini-recommended that comes with 4.3.2. no differences except that i have safe mode on. - i don't set any php.ini settings in .htaccess or httpd.conf. - exactly right, any script randomly produces output and randomly produces no output as evidenced by observation and as recorded in the apache access log. I downgraded to 4.3.1 to correct the problem for now. ------------------------------------------------------------------------ [2003-07-15 22:10:51] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip and cut down your configure line to bare minimum that you need for your pages to work. Are you using output buffering features? (php.ini) What is the diff between your php.ini and the php.ini-dist in the 4.3.2 release? (diff -u) Do you set any php.ini settings in httpd.conf / .htaccess parts that might affect the pages involved? Are you sure it's any script? Even plain <?php echo "foo"; ?> style script? ------------------------------------------------------------------------ [2003-07-15 10:31:06] dhunter at uta dot edu Description: ------------ Pages that worked in 4.3.1 randomly print blank pages in version 4.3.2. There isn't any specific code that produces this quirk. A simple call to the header function to redirect a browser will produce a blank page. Also note the following: 1) error reporting is turned on 2) Using Apache 1.3.27 3) Apache does not segfault, no segfault occurs and child process does not die 4) no errors are reported in apache logs Although the PHP engine and Apache do not report errors, the access log reports a 5 byte file size when a blank page is printed. For example, a page that is normally reported in the access log as 10,000 bytes is reported as 5 bytes when the PHP engine fails.
