Issue: Fatal error in autolink on extremely long articles

Please save your long article in a text file and upload it using the form at the bottom of this page so that we can do some tests. Thanks.

There we go.

In the meantime would disabling the autolinking feature for that forum/namespace temporarily remove this issue?

I'm hesitant to make any changes at the moment for fear of making the problem worse.

If you disable autolinking for that forum it may help, but it could also be slow for another reason, and it only timed out when it was up to autolinks.

Does disabling autolinks in the forum significantly reduce save time? If not, does disabling Link Caching (Settings > Options > VaultWiki: Server Settings) significantly reduce save time? How many articles do you currently have? Are there many titles that would be common words?

It takes a while to save, yes, but I am unable to reach a timeout here with the common word 'was' being autolinked, among others. I doubt that autolinking or link caching has anything to do with it, since both of these also occur when the page is displayed. According to some debug output, the entire parse of an article of this size takes about .5 seconds. So I am led to believe that either something is inefficient in vBulletin's validation of the post text (takes about 12 seconds here), or there is another modification you're using that inflates the time significantly.

We don't have many articles in the forum - perhaps around 200, and most of them are only in length of 3000-1000 words.

I will try disabling some of the cache features like you said, and autolinking (because autolinking isn't actually linking anything for me at the moment but that is because article titles are often extreme unique and never mentioned in other articles).

This is an original issue from a user that I was able to duplicate.

The most significant mod I am using is VBSEO and Vaultwiki. The others include things like merge double post or display thread count - you know, small time stuff. I'll experiment with disabling them.

Can you think of anything else inside of VB that might be causing this? Because I have no problems posting all that text as a single post and then editing it in a standard showthread forum.

As an update: Disabling autolinking in that namespace stopped the error for myself. Confirming with users now.

Yes, but how long does it now take to save? If you could time it, that would be great.

A similar time. I'd say it's hitting the 30 second area again.

Unfortunately, there's not much that can be done to improve this. There are a few settings you can turn on or off, but everything seems to be working as it should. I guess it's just not very advisable to write articles that are 300,000 characters long. This is going to be approaching the limits of what PHP can handle (gracefully) anyway, like when you start using functions with regular expressions, or you will run out of memory if you try to compare diffs on an article of this size.

You might consider breaking it into multiple pages and placing it in a book. If it's already in a book, you can put books in books if you didn't know.

I see. Thanks much for this info. I'll look into doing that.
