Hallo, /* ** PostgreSQL bug on ECPG connection when using Host Variables ** ** Reference: ** http://doxygen.postgresql.org/interfaces_2ecpg_2ecpglib_2misc_8c_source.html#l00512 ** File: ** postgresql-9.1.1/src/interfaces/ecpg/ecpglib/misc.c ** Description: ** Function ECPGset_var() will call calloc() to allocate memory for a new node. ** And all nodes are appended to a static global list named 'static struct var_list'. ** But the list memory is never been freed with free() in any case, and no relative function ** is available for me. After ECPG connection is disconnected, ECPGset_var() resultes ** in memory leak (TotalSize = n * sizeof(struct var_list), where n is maxium ** of Host Variables used in a DB Connection). ** ** Bug Fixing: ** A new function should be added, details as folloging ** void ECPGfree_var() ** { ** struct var_list *workPtr = ivlist; ** while (NULL != workPtr) ** { ** ivlist = (struct var_list *)ivlist->next; ** free(workPtr); ** workPtr = ivlist; ** } ** ** ivlist = NULL; ** } ** ** Also, above function ECPGfree_var() should be called after all SQL queries, and before ** current ECPG connection is going to be closed. */ Best Regards, Gang, Li -- Sent via pgsql-bugs mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
