Category: None Group: None >Status: Closed Priority: 5 Private: No Submitted By: Stefan de Konink (skinkie) Assigned to: Nobody/Anonymous (nobody) >Summary: MAPI: Error message for access denied Initial Comment: The error value for an access denied (for example when a user is not granted to access a table) is set. But the error message is not. My suggestion is to set the in mapilib message, my strlen crashed, so I expect it was returning a null value. I have fixed my code by adding a null check. ---------------------------------------------------------------------- >Comment By: Fabian (mr-meltdown) Date: 2009-12-01 10:00 Message: we'll stick with plain old Mapi, so this feature request boils down to a RTFC ---------------------------------------------------------------------- Comment By: Fabian (mr-meltdown) Date: 2009-07-13 10:41 Message: this is more of a feature request that gijs is going to tackle ---------------------------------------------------------------------- Comment By: Fabian (mr-meltdown) Date: 2009-06-28 21:42 Message: I agree, it's almost impossible to pick the right function for the error at hand. ---------------------------------------------------------------------- Comment By: Stefan de Konink (skinkie) Date: 2009-06-28 21:38 Message: > Can you shed some light on how you would describe the difference between "error value" and "error message"? Ofcourse; as the documentation on <http://monetdb.cwi.nl/projects/monetdb/SQL/Documentation/Mapi-Function-Reference.html> explains the user: MapiMsg mapi_error(Mapi mid) Return the last error code or 0 if there is no error. > In particular what the "error value" for an "access denied" is. While: char *mapi_error_str(Mapi mid) Return a pointer to the last error message. or char *mapi_result_error(MapiHdl hdl) Return a pointer to the last error message from the server. So what a user of the mapilib expects here is that MapiMsg is a value upon error or 0 if there is no error. Now if I should use mapi_error_str or mapi_result_error, or as suggested <http://monetdb.cwi.nl/XQuery/Documentation/Library-Synopsis.html> (notice the typo) map_explain_result() is open to me. ---------------------------------------------------------------------- Comment By: Fabian (mr-meltdown) Date: 2009-06-28 21:29 Message: /* Render error reply */ cherokee_dwriter_dict_open (&hdl->writer); add_cstr_int (&hdl->writer, "SUCCESS", false); add_cstr_int (&hdl->writer, "MONETDB_ERRNO", mapi_error(dbh)); tmp = mapi_result_error(resHdl); if (tmp) add_cstr_str (&hdl->writer, "MONETDB_ERROR", tmp, strlen(tmp)); Can you shed some light on how you would describe the difference between "error value" and "error message"?
