Need to downgrade pcre from 8.21 to 8.20

[chrismfz]

Forgot the first 2 commands. Entering the sources folder and extracting pcre.

[oldlock]

Still returns an error. Screenshot attached.



I did the commands from the beginning.

for the most part the info above worked. but I got a malformed line when I did the echo, here is what i did to make it work

cd /var/cpanel/perl/easy/Cpanel/Easy/OptLib
tar -xzvf pcre.pm.tar.gz

created a patch file called pcre_patch & added this to it.

patch -p1 < pcre_patch
it might ask for the filename to patch, I just typed pcre-8.21/pcre_compile.c
and it patched the file.

then I just ran the rest of the commands from above

tar -czvf pcre.pm.tar.gz pcre-8.21/
rm -Rf pcre-8.21/
chattr +i pcre.pm.tar.gz
rm -Rf /opt/pcre/
/scripts/easyapache --build
chattr -i pcre.pm.tar.gz

My forums are now working again...I'm a happy camper
the code for the patch came from this post http://bugs.exim.org/show_bug.cgi?id=1187

What is the extension for the patch file you created ? Could you detail the steps involved precisely ?

[oldlock]

There's a couple of inconsistencies in your file names too ??

[oldlock]

Here's the error message that presents ..

[Worelock]

you copied the text from the other site...not the code for the patch I posted.
i removed the code/trunk/ from the file name in my code above.

You don't need an extension for the patch either...its just a plain old text file that i created in the /var/cpanel/perl/easy/Cpanel/Easy/OptLib using the command nano pcre_patch

Interesting dont have a problem with this on my WHM server with PHP 5.3.10 but seems i'm running PCRE version 8.12 not 8.21 with CentOS 5.7.

[Worelock]

possibly because you upgraded to 5.3.10 before the pcre libraries where updated?

Thanks for your help.

I've copied the text exactly and the error still presents ?

[Worelock]

i did post in my first post that it might ask you what file to patch...and i typed pcre_compile.c when it did what yours did in the screenshot

[anwarx]

non of this methods works for me !

If you are following his directions, when it asks for the file, enter "pcre-8.21/pcre_compile.c"

The patch failed when I tried to follow this advice. I just edited the pcre_compile.c file myself instead for that step.

To do so, I just found line 1655 in /var/cpanel/perl/easy/Cpanel/Easy/OptLib/pcre-8.21/pcre_compile.c and replaced:

case OP_ASSERTBACK:
case OP_ASSERTBACK_NOT:
do cc += GET(cc, 1); while (*cc == OP_ALT);
/* Fall through */

with:

case OP_ASSERTBACK:
case OP_ASSERTBACK_NOT:
do cc += GET(cc, 1); while (*cc == OP_ALT);
cc += _pcre_OP_lengths[*cc];
break;

yea..my bad, should have added the pcre-8.21/ in front of the file name
I have edited the original post.
