Bug #: 31130
Summary: CharInsert generates an error in Linker.php
Product: MediaWiki extensions
Version: any
Platform: All
OS/Version: All
Status: NEW
Severity: major
Priority: Unprioritized
Component: CharInsert
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Warning: preg_match() [function.preg-match]: Empty regular expression in
/home/zeldaw/public_html/includes/Linker.php on line 1466
After upgrading to MediaWiki 1.17.0 and PHP 5.3.2, I found that this extension
generated the above error on our wiki. Since I couldn't find anywhere in
CharInsert.php which was obviously making a call to this (or any) function in
Linker.php, I instead went to includes/Linker.php to analyse the indicated
line.
I found that I could work around this by modifying Linker.php to comment out
line 1459 (if ( $regex === false ) {) and the closing brace on line 1462, such
that the error is no longer generated.
