Previous Comments: ------------------------------------------------------------------------ [2006-11-28 17:48:01] matteo at beccati dot com Description: ------------ While toying with the pgsql extesion I found that the pgsql_notify struct is not freed as pointed out in the PostgreSQL documentation: "After processing a PGnotify object returned by PQnotifies, be sure to free it with PQfreemem." (see: http://www.postgresql.org/docs/8.1/interactive/libpq-notify.html ). This could lead to memory leaks as far as I can see. Reproduce code: --------------- Here is the patch: --- ext/pgsql/pgsql.c 2006-10-06 23:45:10.000000000 +0200 +++ ext/pgsql/pgsql_new.c 2006-11-28 18:21:40.000000000 +0100 @@ -4347,6 +4347,8 @@ add_assoc_string(return_value, "message", pgsql_notify->relname, 1); add_assoc_long(return_value, "pid", pgsql_notify->be_pid); } + + PQfreemem(pgsql_notify); } /* }}} */ BTW, pg_*_bytea functions should use PQfreemem too, even if it is simply a wrapper. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39663&edit=1
