[DBTech] vB Optimise 2.0.1 (Lite) Details »»
|
|||||||||||||||||||||||||||
vB Optimise Lite
The newly revamped vB Optimise was created for vBulletin 4, but has now been made compatible for vBulletin 3.8. In this release I have re-coded vB Optimise from the gound and focused stability over features, you'll notice Phrase Caching and vBAdvanced Integration have bit the dust, this is to maintain a sync state between this version and the vBulletin 4 release. Professional version & feature list available @ www.DragonByte-Tech.com/forum Priority support for Lite version is handled at the Developers Website. What does it do? vB Optimise is intended to optimise vBulletin software by integrating several PHP "cachers" and handling data before vBulletin. This works by encountering and handling data prior to vBulletin in order to skip the arbitary execution that would be more server intensive. Real-Life Statistics We've teamed up with some Big Forums to show you the impact of vB Optimise, you can view this public chart which shows both our statistics and theirs: View Public vB Optimise Resource Statistics Features
Features - Pro
Release Notes If you've used vB Optimise before you'll be aware the previous version had phrase caching, however this caused complications with the way phrases are used within vBulletin so it has not been ported over at this time. Available Translations v1.6.0 French - Thanks to finereader Change Log [>>] Version 2.0.1 New launch for vB 3.8 [>>] Version 1.6.1 Automatic Cache Flusher has additional parameters to make sure no data is stale Resolved Bug: Potential PHP error when using eAccelerator which cannot flush within Admin CP on certain actions [>>] Version 1.6.0 New OpCode Cacher Support: WinCache [>>] Version 1.5.0 Resolved Bug: Style cache may have fetched ID 0 instead of correct file Resolved Bug: Filecache permissions may not have worked Optimisation: Re-wrote some base code to enhance operations. [>>] Version 1.0.1 Added XCache Authentification Support Added Filecache Support Support Priority support will be handled at DBTech. FAQ Q: I have WinCache installed, but vB Optimise tells me it's not? A: WinCache only introduced OpCode support in version 1.1, if you're using version 1.0.x you will need to upgrade. Q: I'm using the XCache method, flushing doesn't work? A: If you have XCache authentification, turn the admin option on within vB Optimise Settings, then edit ./vboptimise/config.php and specify your XCache username/password. Alternatively you can disable XCache authentification within php.ini: Code:
xcache.admin.enable_auth = Off A: eAccelerator does not provide the caching extension by default, you will need to recompile PHP with additional flags. For more information read eAccelerator documentation located here: http://eaccelerator.net/wiki/CompileConfiguration (Specifically look at: with-eaccelerator-shared-memory) Download Now

What templates are blank exactly Jim_O? (You put 'xxxxx' in your post).
In either case, the php error is caused by the xcache script because it didn't anticpate for blank variables, you could probably edit the script and change htmlspecialchars to @htmlspecialchars on line 4.

Quote:
Pretty much anything that starts with "vbactivecache_template_" is empty. When there is what appears to be an intentionally blank cache, such as "vbactivecache_phrase_calformat2override_1" it shows the following data: "{_______VB_ACTIVE_CACHE_BLANK_______}" These others are simply blank. Many have multiple hits and "sizes" as large as 15K. FWIW, if you are interested in system info, I am using XCache 1.2.2 which I compiled from source and run php 5.2.8 as a fastcgi using php-fpm as a controller, also compiled from source. The web server is nginx 0.7.27. No other scripts are accessing XCache and the system seems to be running fine although volume is very light at this moment with people out Christmas shopping or whatever else that they might be doing this time of year.

Jim_O - Where you see the numbers, run this query:
[sql]select * from template where templateid = xxx[/sql] You'll probably need to put your table prefix before "template". My guess is you've uninstalled templates, but mods are still trying to run them. But if I'm wrong let me know the result of your query, and if the template in your database actually has any information.

Nope. Those queries return lots of data.
For instance: select * from vb_template where templateid = 8110: Quote:
select * from vb_template where templateid = 13045 Quote:
So these are some fairly standard templates it would seem. I do have styles that are unavailable for users to select, but enabling them, flushing the cache and looking again made no difference on the empties. Like I said, all template caches appear to be empty.

For some reason the template content isn't being cached. If you turn on vB debug mode, does vB optimise tell you it's fetched templates from cache, or that it needs to query them to cache?
If unsure where vB Optimise messages are, it's the bottom drop down menu on your pages after enabling debug mode, which can be done like so by adding this in config.php: Code:
$config['Misc']['debug'] = 1;

It says that it got 86 templates from the cache and 0 fetched from the database so it seems to be working.
Maybe it's best I ignore what XCache is telling me (?), though it seems odd, and it only appears with this product.

When vB Optimise is active, when clicking the save button after editing a post, the revised data is saved into the database, but the screen is left at the editor mode instead of refreshing into a normal post display.
