That is a *very* inaccurate description. It affects only session handler functions which are called during the request shutdown (write, close). It does not affect the other four handlers. Second, it is not a general problem with memory allocations. Strtok just assumed that it would not be called after request shutdown. The attached patch should fix that. - Sascha Experience IRCG http://schumann.cx/http://schumann.cx/ircg Index: basic_functions.c === RCS file: /repository/php4/ext/standard/basic_functions.c,v retrieving revision 1.355 diff -u -r1.355 basic_functions.c --- basic_functions.c 2001/07/04 10:10:29 1.355 +++ basic_functions.c 2001/07/08 23:09:25 @@ -885,6 +885,7 @@ BLS_FETCH(); STR_FREE(BG(strtok_string)); + BG(strtok_string) = NULL; #ifdef HAVE_PUTENV zend_hash_destroy(&BG(putenv_ht)); #endif -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

There is a serious bug in PHP that seems to lead to inconsistent handling of memory allocation that affects code that uses functions like strtok from inside session handler functions. A new version of Metabase that does not use strtok was uploaded to the PHP Classes site. Everybody that uses Metabase for session handling is encouraged to download this version because PHP trashes the memory and eventually crashes you Web server when the strtok function is used. http://phpclasses.UpperDesign.com/browse.html/package/20 Regards, Manuel Lemos Web Programming Components using PHP Classes.

[PHP] Help with custom session handler
I'm writing a custom session handler that saves sessions using Manuel Lemos' excellent Metabase library. The problem is, although I've got the session_set_save_handler function pointing to the correct start, end, read, write, destroy and garbage collection functions, when I call session_start and session_register, the "write" function does not get called (the only function that gets called is the "read" function.) I read on a post at PHPBuilder that the write function cannot output to the browser so just to make sure I logged my debug code to a global variable and it really is not getting called. I'd really appreciate any suggestions you might have -- it's got me stumped! Thanks, Aral :) __ ([EMAIL PROTECTED]) New Media Producer, Kismia, Inc. ([EMAIL PROTECTED]) Adj.
