PHP Bug Type: Informix related
Bug description: HTTP memory increased
Description:
------------
Our developers created a sample code by using the following functions.
--- ifx_connect(), ifx_query(), ifx_free_result(), ifx_close()
This sample program is very simple such as connect to Infomix DB and then
issue some query string, get query result, and finally disconnect Informix
DB. They executed this sample php code several times. Then, they found a
problem that HTTPD used memory was increased. This is kind of memory leak
problem.
They also investigated php_initfx_count_descriptors() function.
static php_initfx_count_descriptors(char *p_statemid TSRMLS_DC)
{
EXEC SQL BEGIN DECLARE SECTION;
char *statemid = p_statemid;
EXEC SQL END DECLARE SECTION;
struct sqlda *s_da;
int ret = 384;
EXEC SQL DESCRIBE :statemid INTO s_da;
If(ifx_check()) >= 0) {
ret = s_da->sqlid;
/*
*Thanks to DBD-Informix
*/
#if (ESQLC_VERSION >= 720 || (ESQLC_VERSION >= 501 && ESQLC_VERSION <
600))
SqlFreeMem(s_da, SQLDA_FREE);
} else {
free(s_da);
#endif
}
return ret;
}
