Board Optimizations - vB AJAX Cron

vB AJAX Cron From vBModder.com

This is such a small but useful mod that I decided to give it away free. This mod will replace your sheduled task image code at the bottom of your pages and run your sheduled tasks via an AJAX call.

AJAX is asyncronous and offers true background running of sheduled tasks. This does not change anything with the actual tasks or the scripts that run them. It merely replaces the method that initiates the running of those scripts.

There are no template edits of any kind. Simply upload the files to your forumhome directory and import the product xml file. Both 3.5x and 3.6x xml files are included. Make sure you use the right one as there are changes in crons with 3.6x.

This should work in any vb or custom script in any directory.
Support will only be given at vbmodder.com

Enjoy

will this run crons even if the forum has no users or if the forum is closed?

No, someone has to load a page it activate it just like vbcron.

"your sheduled task image code at the bottom of your pages"
=> What is it? monkey, please tell me.

Thanks, this is a cool hack but just difficult to detect any sort of performance difference. Regardless, its a nifty feel-good at the least.

You have to test it on a test forum where you will get all the cron hits. The bigger the user database the longer some crons run.

One person at vBORG has stated that the image cron has never worked on his server and jelsoft could never answer why. It works now with this so it's a good thing.

New version 1.1.2

Added ajax_cron_start hook. Now if you should ever have a plugin that uses the cron_start hook simply change it to use the ajax_cron_start hook.

do you know of anyway I can get a cron to run while my site is offline?

Code Monkey · 08-18-2006, 02:50 AM

For that you need a server cron. However, you would have to do some serious hacking of the vb files to get them to run outside the vb environment.

It's been a topic of discusion for some time because the image code was a pain.

However, if your site is offline what crons does it need to run?

Most of them update views and such. No views when your offline.

New Version 1.1.3

Now it will just use cron_start hook if you have a plugin that uses it. Aparently vb doesn't actually care where the hook is located.

Live and learn.

New Version 1.1.4

This will now degrade gracefully when browsers have javascript turned off. When a browser has javascript turned off the default vb method will be implemented to ensure the cron runs.
