ZEND_HANDLE_FD handling not fully implemented ?

Hello, I'm writing an Apache module that must communicate with mod_php4 (see below). The data that must be parsed by the Zend scanner won't come from a filename but from a file descriptor. It seems that data source is described by a "zend_file_handle" object (in sapi.sapi_apache.c). This structure has a type "field" wichi value can be ZEND_HANDLE_FILENAME or ZEND_HANDLE_FD. But in fact, I had to patch apache_php_module_main() function to make mod_php4 handle correctly a ZEND_HANDLE_FD. Is that a bug or a feature ? Will it be possible to expect ZEND_HANDLE_FD work fine in a future version ? Thanks, Jerome P.S: to explain how I want to call mod_php4, I get the address of the request handler for content-type "application/x-httpd-php" and call it paasing it the Apache request_rec * structure this way: fd = open(.....); sprintf(buff,"%d",fd); r->filename = buf; (*handler)(r); close(fd); and I have patched sapi/sapi_apache.c this way (it's ugly but it works): if (atoi(r->filename) <= 0) { /* standard way: */ file_handle.type = ZEND_HANDLE_FILENAME; file_handle.handle.fd = 0; file_handle.filename = SG(request_info).path_translated; } else { /* hack: */ file_handle.type = ZEND_HANDLE_FD; file_handle.handle.fd = atoi(r->filename); file_handle.filename = r->filename; }
