I suspect the real reason is the massive number of IP addresses that will come back in the results list and ALL of those have to be buffered and then run through the URL "tapping", which uses string search and replaces on a massive scale, thereby the attempts to allocate even yet more memory.

These are all good ideas. Thanks guys!

Does the entire content of a page pass through Shortlinks? I thought it was only the link of the page.

I hadn't thought of that montego, hmm, sounds like the culprit.

I have tried to tap this link, but failed.

In .htaccess I added:

RewriteRule ^ftopic-ip-([0-9]*)-([0-9]*).html modules.php?name=Forums&file=modcp&mode=ip&p=$1&t=$2 [L]

In GT-Forums.php

'"(?<!/)modules.php\?name=Forums&file=modcp&mode=ip&p=([0-9]*)&t=([0-9]*)"',

Can this failure provide some info?

Yes, as I stated above, the entire page is buffered using the output buffer functions and then ShortLinks runs through the buffer with search and replace. Normally this isn't an issue because pages are generally quite small in size. Not so in this case.

The tapping of the link has nothing to do with the error. However, I cannot comment on whether your "tap" is correct or not because you have not shown me the $urlout line for that "tap"....

Thanks. Here is the original link from my local test server:

http://localhost/nuke/modules.php?name=Forums&file=modcp&mode=ip&p=92921&t=9584&sid=7c4f6302338f756f15d5bd6ddcae7038

No, I mean the $urlout line for that tap you made in GT-Forums.php...

You had given above only the $urlin line.

Ok, I have a potential "fix" for you to try.

=== OPEN FILE ===

mainfile.php

=== FIND CODE ===

Code:

if (isset($tnsl_bUseShortLinks) && $tnsl_bUseShortLinks && file_exists(INCLUDE_PATH.'includes/tegonuke/shortlinks/shortlinks.php')) {
define('TNSL_USE_SHORTLINKS', TRUE);
@include_once(INCLUDE_PATH.'includes/tegonuke/shortlinks/shortlinks.php');
}

=== REPLACE WITH ===

Code:

if ((isset($name) && isset($file)) && ($name == 'Forums' && $file == 'modcp')) {
} else {
if (isset($tnsl_bUseShortLinks) && $tnsl_bUseShortLinks && file_exists(INCLUDE_PATH.'includes/tegonuke/shortlinks/shortlinks.php')) {
define('TNSL_USE_SHORTLINKS', TRUE);
@include_once(INCLUDE_PATH.'includes/tegonuke/shortlinks/shortlinks.php');
}
}

=== DONE ===

Now, what this will do is keep ShortLinks from even buffering any Moderator Control Panel type page. There will be no impact to Search Engine crawling and caching (since anonymous users cannot be moderators).

However, just so you know, this one IP look up functionality was never meant to be used on anonymous user. Eventually, you will still blow your memory limitation and it will have nothing to do with ShortLinks.

Many thanks! I have just tested it and it worked. I looked at this error at phpbb.com forum and found an old post, which showed that it had happened earlier to someone with only 8 MB of memory (without Shortlinks of course).

BTW, for the RavenNuke'ers out there that run into this, I have fixed this already for the upcoming 2.3.0 release.
