Redirect bug

Redirect only works once

I created a redirect from one article to another. The first time after you save the article, the redirect works. But any subsequent time you visit that article, it just shows the raw bb code and the redirect no longer works.

Any ideas?

Thanks.

Fixed for the next build. In vault/tab/article.php, find:

Code:

		$wikipost_factory->bbcode_parser = new vB_WikiCodeParser($vbulletin, special_tag_list('', true));

Add after:

Code:

		$wikipost_obj->bbcode_parser =& $wikipost_factory->bbcode_parser;
		$wikipost_obj->post_cache =& $wikipost_factory->bbcode_parser->cached;

In vault/factory/postbit.php, find:

Code:

		$out->post_cache =& $this->post_cache;

Replace with:

Code:

		$out->post_cache =& $this->bbcode_parser->cached;

I'm afraid that doesn't fix the issue on my end. The redirect continues to work once then when you go to the page again, it's unparsed BB code.

It will continue to show the same behavior as before for articles created before the fix was implemented until the cache times out. You can clear the cache manually by going to AdminCP > VaultWiki > Wiki Maintenance Tools > Clean Article Post Cache.

The issues remains I did clean the cache.

If you need access to my site, I'm willing to provide it if you can't recreate the problem on your end.

This only occurs for wikis that are set to display the comments below the article. On the first time it parses, you will notice a comment below the article that contains the raw code of the article. This comment even being there is a bug, and when it caches it overwrites the cache for the article. The comment disappears on subsequent page loads because there is no longer an id mismatch, because the cache prevented the redirect from taking place.

The problem is that when the article changes during the redirect, the value of $threadid is not also changed because it is not a reference to $threadinfo['threadid'].

In vault/class/bbcode/redirect.php, find:

Code:

$threadinfo = fetch_threadinfo($targetid);

Add after:

Code:

$GLOBALS['threadid'] =& $threadinfo['threadid'];

And in vault/functions/cache.php, find:

Code:

$postobj->thread = fetch_threadinfo($temp_cache['threadid']);

Add after:

Code:

$GLOBALS['threadid'] =& $postobj->thread['threadid'];

I appreciate your continued support on this. It looks like the redirect is working now, however, the comments below the page are doing something weirder now. See: http://www.crohnsforum.com/wiki/Ibd

Thanks.

That is a separate (yet related) bug: http://www.vaultwiki.org/issues/1970/

The fix has already been added to my previous post in this thread.

Another associated issue I'm afraid. When a redirect is created for a new article that hasn't been read, when visiting that article, it is not marked as read on forumdisplay. You can see it here: http://www.crohnsforum.com/forumdisplay.php?f=56 Tylenol, acetomephotin, etc.

Please open a new thread for that issue, as it's a different problem than the OP.
