Operating system: SuSE SLES8 on IBM mainframe
PHP version: 4.3.4
PHP Bug Type: Session related
Bug description: Zero length session files in /tmp
Description:
------------
Hi...
I have a script that runs on other platforms, but I can't get it to work
on this platform. (I suspect it's not a PHP code bug, but haven't been
able to find a problem in the setup or anything I've done.)
The problem is that PHP creates a sess... file in /tmp (which is global
read/write/execute), but the file ALWAYS has zero bytes, which of course
means the next screen fails becuase it can't get it's assumed data...
The code below is a truly trivial test case which fails. The test case
also fails the same way with the new style session support. (The full
application is quite large and it's not reasonable to go convert the
entire application to the new style.) The code does the same with or
without a session_write_close() call.
The "real" code runs on a PHP 4.3.4 system that's not net accessible. But
the code fails the same on a similar (SuSE SLES8 on and IBM mainframe with
PHP 4.2.2) system that is web accessible. You can run the test for
yourself at www.sytek-services.com/page1.php. And you can also see the
PHP Info page for that system at www.sytek-services.com/phpinfo.php.
Like I said, I suspect it's something in the setup, but I've not been able
to find out what... Thanks for any help or pointers...
