I just downloaded a snapshot of 5.2 to check and its definitely fixed. Memory peaks at 4mb, you must be doing something wrong. Previous Comments: ------------------------------------------------------------------------ [2009-05-29 21:39:03] bmorel at ssi dot fr Thanks, but the problem is still there in the latest snapshots. Just verified it on : php5.2-200905292030 php5.3-200905292030 php6.0-200905292030 Memory usage still gets so high ! Ben ------------------------------------------------------------------------ [2009-05-29 00:06:16] scott...@php.net Fixed in 5.2 as well now. ------------------------------------------------------------------------ [2009-05-28 21:58:10] scott...@php.net This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. Added a LRU and a cache limit to the ereg code for 5.3. Give it a few hours and grab another 5.3 snapshot, not sure about fixing this in 5.2. Will check with ilia. ------------------------------------------------------------------------ [2009-05-28 18:17:49] bmorel at ssi dot fr Sorry, same problem with this snapshot (PHP 5.3.0RC3-dev : php5.3-200905281630). The cache seems to be a good explanation, but it this a good idea ? I have millions of ereg()s done when I parse huge XML files (several GB), and my memory usage goes too high. I had to replace all my ereg()s with preg_match()s. Thanks, Ben ------------------------------------------------------------------------ [2009-05-28 17:30:21] scott...@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.3-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Pretty sure this is due to the regular expression cache we have, each unique regular expression is cached so we don't keep compiling it but there is no cap on the number we store. Can you try a 5.3 snapshot, I think we switched from using ereg to pcre with 5.3. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
