#47919 ldbm_back_modify SLAPI_PLUGIN_BE_PRE_MODIFY_FN does not return even if one of the preop plugins fails.
Closed: wontfix None Opened 5 years ago by nhosoi.

If opreturn is SLAPI_PLUGIN_NOOP, it returns at the line 644, but if opreturn is non-zero (e.g., SLAPI_PLUGIN_FAILURE), it goes forward.

 389 int
 390 ldbm_back_modify( Slapi_PBlock *pb )
 630             opreturn = plugin_call_plugins(pb, SLAPI_PLUGIN_BE_PRE_MODIFY_FN);
 631             if (opreturn ||
 632                 (slapi_pblock_get(pb, SLAPI_RESULT_CODE, &ldap_result_code) && ldap_result_code) ||
 633                 (slapi_pblock_get(pb, SLAPI_PLUGIN_OPRETURN, &opreturn) && opreturn)) {
 634                 slapi_pblock_get(pb, SLAPI_RESULT_CODE, &ldap_result_code);
 635                 slapi_pblock_get(pb, SLAPI_PLUGIN_OPRETURN, &opreturn);
 636                 if (!ldap_result_code) {
 637                     LDAPDebug0Args(LDAP_DEBUG_ANY, "ldbm_back_modify: SLAPI_PLUGIN_BE_PRE_MODIFY_FN "
 638                                "returned error but did not set SLAPI_RESULT_CODE\n");
 639                     ldap_result_code = LDAP_OPERATIONS_ERROR;
 640                 }
 641                 if (SLAPI_PLUGIN_NOOP == opreturn) {
 642                     not_an_error = 1;
 643                     rc = opreturn = LDAP_SUCCESS;
 644                     goto error_return;
 645                 } else if (!opreturn) {
 646                     opreturn = -1;
 647                     slapi_pblock_set(pb, SLAPI_PLUGIN_OPRETURN, &opreturn);
 648                 }
 649             }

Historically, the return value of plugins were just ignored and the process goes forward in the backend. But it's strictly checked now. (See SLAPI_PLUGIN_BE_PRE_{ADD,DELETE,MODRDN}_FN.) SLAPI_PLUGIN_BE_PRE_MODIFY_FN should follow the rule.

A workaround is in place but a fix is expected (as soon as possible) in 1.3.2
