[Forum] VBulletin 4.1.0 and PCRE 8.21 : bug

[XLD_Bull]

Hello,

I have just upgraded PCRE on my server to the 8.21 version and it caused bug on my forum.
My Vbulletin is 4.1.0.
When a message is entered, the following message comes and the message is empty :
"Warning :Preg_replace()[function.preg-replace] :Compilation failed : internal error :unknow opcode in find_fixedlength() at offset 193 in [path]/includes/functions_newpost.php on line 279"

When coming back to PCRE 8.20, it works.

Is it a known bug?

Thanks

David

Please upgrade to 4.1.9... Does the problem still exist?

Hi,

Unfortunately I plan to migrate to VB4.1.9 in next months.
I have to do non regression tests, correct templates...

Did you ever heard about such issues?

Only in older versions of the software. Unfortunately, I can't provide a fix at this time except to either downgrade PCRE or upgrade.

Hi,

I have migrated to VB4.1.9 yesterday and tried to upgrade PCRE to 8.21.
I have the same issue than with VB4.1.0

An idea to fix the issue?

Thanks

Issue appears to be a bug in PCRE 8.21. I recommend downgrading to 8.20 until they get it fixed.

Help

URGENT PATCH REQUESTED !

This is not a vbulletin bug, it is a PCRE bug. The only fix is to downgrade your PCRE to 8.20 for now.

Same problem here, I upgrade to latest version of vB 4.1.9 and still continue with the problem.

When the users create new post, reply or private message appear in blank with the error msg.

My host provider of course is not going to downgrade his host.

Please fix the problem!!!!!! The board is not working well!!!!!

Regards.

The problem at this time is a bug in the library, not vBulletin.

Probably its PCRE fault, but the Developers has to be helped in order to find a solution, when all users will be upgraded to the new edition. This has to be done, because the program provider will be tagged with tickets.

I would imagine that given the error message, it was this change [as listed in their 8.21 changelog] that is causing the problem.

Warning :Preg_replace()[function.preg-replace] :
Compilation failed : internal error :unknow opcode in find_fixedlength() at offset 193 in [path]/includes/functions_newpost.php on line 279

7. While fixing 6 above, I noticed that a number of other items were being
incorrectly rejected as "not fixed length". This arose partly because newer
opcodes had not been added to the fixed-length checking code. I have (a)
corrected the bug and added tests for these items, and (b) arranged for an
error to occur if an unknown opcode is encountered while checking for fixed
length instead of just assuming "not fixed length". The items that were
rejected were: (*ACCEPT), (*COMMIT), (*FAIL), (*MARK), (*PRUNE), (*SKIP),
(*THEN), \h, \H, \v, \V, and single character negative classes with fixed
repetitions, e.g. [^a]{3}, with and without PCRE_CASELESS.

Now at least the post are not in blank but the signatures don't work. But its better than a lot of blank post in the forum.

Please notify in this post when some change happens in PCRE or in vBulletin for put the code as normal.

Same problem exists with PCRE 8.21 and VBulletin 3.8.x.

Same problem exists with PCRE 8.21 and VBulletin 3.8.x.

As I mentioned in a post somewhere - that code (in vb) is basically the same in all 3.x versions (right back to 3.0.0).

Indeed it may well be in vb2 as well, I didnt check.
