#34121 [NEW]: Add DFA support to preg_match() function

From: nlopess@php.net Operating system: * PHP version: 5CVS-2005-08-13 (dev) PHP Bug Type: Feature/Change Request Bug description: Add DFA support to preg_match() function Description: ------------ I've made a patch to add DFA (PCRE 6) support to preg_match(). It isn't completed (yet), because I would like to receive your feedback first before continuing. patch: http://mega.ist.utl.pt/~ncpl/php_pcre_dfa.txt example: http://mega.ist.utl.pt/~ncpl/dfa_example.php TODO: - currently preg_match_*() allocs memory for captures based on the number of capturing parentheses. But this needs to be changed for the DFA mode. - make partial matching working. The only thing it needs to be done is to save the workspace table in the cache and reuse it when calling the pcre_dfa_exec() function. -- Edit bug report at http://bugs.php.net/?id=34121&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34121&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34121&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34121&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34121&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34121&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34121&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34121&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34121&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34121&r=support Expected behavior: http://bugs.php.net/fix.php?id=34121&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34121&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34121&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34121&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34121&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34121&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34121&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34121&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34121&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34121&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34121&r=mysqlcfg
