-- CREATE_FUNCTION_C
--
-- This script used to create C functions for other scripts to use.
-- But to get rid of the ordering dependencies that caused, such
-- functions are now made either in test_setup.sql or in the specific
-- test script that needs them. All that remains here is error cases.
-- directory path and dlsuffix are passed to us in environment variables
\getenv libdir PG_LIBDIR
\getenv dlsuffix PG_DLSUFFIX
\set regresslib :libdir '/regress' :dlsuffix
--
-- Check LOAD command. (The alternative of implicitly loading the library
-- is checked in many other test scripts.)
--
LOAD :'regresslib';
-- Things that shouldn't work:
CREATE FUNCTION test1 (int) RETURNS int LANGUAGE C
AS 'nosuchfile';
ERROR: could not access file "nosuchfile": No such file or directory
-- To produce stable regression test output, we have to filter the name
-- of the regresslib file out of the error message in this test.
\set VERBOSITY sqlstate
CREATE FUNCTION test1 (int) RETURNS int LANGUAGE C
AS :'regresslib', 'nosuchsymbol';
ERROR: 42883
\set VERBOSITY default
SELECT regexp_replace(:'LAST_ERROR_MESSAGE', 'file ".*"', 'file "..."');
