 Posted: Tue May 30, 2006 12:05 pm Post subject: Custom Error Pages weirdness |
 |
|
I am having problems with my office setup. I don't know where the difference lies but I already had this working at my home setup. I have the same Abyss 2.3.0.5 version at home and here in my office PC. The PHP version I have here in the office is 5.0.3, while it's also 5.x.x at home (hehehe will have to get this info when I get home). Nothing seems to be amiss in abyss.conf.
For some reason, setting a Custom 404 Error Page to a php handler would not commit, i.e. Abyss' standard error 404 is being displayed. | Quote: | Error 404
Not Found
Powered by Abyss Web Server X1
© Aprelium Technologies - 2001-2006 |
But if I post a gif or htm handler, the Custom 404 Error Page works! Compounding the confusion is that I am INDEED able to run php pages here with no apparent problems at all! I've tried setting the handler to my own custom url_rewrite.php and then some stock php like phpinfo.php (implied content) or webfilebrowser.php (implied content) - they each won't work as a Custom 404 Error Page! But if I put in a gif or an htm file, it works! And the webserver can in fact read phpinfo.php and webfilebrowser.php if I requested them directly.
What's going on? What kind of technical voodoo is this? It's gotten me dazed and confused. Can anybody shed some light on this?
Update: I have now been able to replicate the problem on another office machine. This doesn't seem to be an isolated quirk.

I'm beginning to think that this is not a PHP problem but could well be a server problem. Here are the responses of Abyss for:

This error means that Abyss Web Server was unable to find the PHP file you wanted it to run when an error occurs. Check that the virtual path you've set for the PHP custom error script is correct: the easiest way is to browse it directly. Or if you have trouble setting it, press the Browse button next to the Virtual Path field (in the Custom error screen) to locate it.

Sadly, I did use the Browse button in my tests above. And my PHP pages do work if browsed directly.

Can you please post the PHP page source code here? Can try using a very simple PHP page and see if it makes any difference?

This problem was solved when I installed Aprelium's pre-packaged PHP5 found at http://www.aprelium.com/abyssws/php5win.html. Therefore, the problem must lie within PHP 5.0.3, or somewhere in my package copy.
There appears to be something amiss in my former php.ini. I shall try to identify the relevant differences between that and Aprelium's php.ini.

loloyd,
Thank you for your update. We were unable to reproduce the problem hence our "silence".
Could you please do the comparison and let us know what were the differences?

I have tried two approaches but, sadly, I am unable to determine where the significant differences in the php.ini settings lie. The first approach was to configure each individual ini setting from the 5.1.4 to 5.0.3; and the second is only vice versa. There may very well be a combination of ini settings that I was not able to test. (Incidentally, my Drupal website wouldn't run on Aprelium's packaged PHP 5.1.4 - isn't this just a lovely chronic troubleshooter's dream?).
Barring any sound intelligent solution, my quick and ugly fix was to install 5.1.4 in C:\Program Files\PHP5 and let my original 5.0.3 remain intact in C:\PHP. I therefore copied exactly the same rewrite file url_rewrite.php onto url_rewrite.php5. Finally, I set PHP 5.1.4 to handle files with a .php5 extension, yet leaving the envar PHPRC pointing C:\PHP. Of course, I had to declare url_rewrite.php5 as my new 404 error handler.
Dirty? Yes. Sound? No. But it solves all problems. Drupal works. URL rewrite works. Cost: around 20 megs of disk space.
Here are the notable differences in the directive

OR, this might just well be another classic case of PEBKAC.

loloyd,
Many thanks for the very detailed report. It will help us track this weird behavior.
PHP 5.0.x and PHP 5.1.y have several internal differences which could explain what you have experienced.
PHP 5.1.4 should also work fine with Drupal. It is probably one of the php.ini parameters related to the prefilled variables that is not compatible with your current setup of Drupal.

Hmm... the curiosity remains. I have no idea how Abyss executes a script via a pre-declared PHP interpreter, all the while passing also the required HTTP parameters and variables (to/from STDIO?). And I wonder why, when given only a single PHP interpreter, a 404 handler would behave differently as opposed to requesting the URI directly.
One thing for sure is that this definitely falls under "PHP Issues". :-D

The CGI specification is probably the best reading to understand how it works: http://hoohoo.ncsa.uiuc.edu/cgi/ .

Browsing /error.php and having /error.php invoked as a custom error script do not work the same way. Actually it is the "environment" which is not the same. In the second case, information about the original URI and the error is added and the call is made internally (it's an internal redirection inside the server).
