Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: SQL/Core Group: SQL CVS Head Status: Open Resolution: None Priority: 5 Private: No Submitted By: Arjen de Rijke (arjenderijke) Assigned to: Niels Nes (nielsnes) Summary: function call not handled Initial Comment: When the result of a function call within a function is assigned to a variable and that variable is not used in the calling function, the called function is never executed. The attached file demonstrates this behaviour. It also explaines the failing of sql test src/test/Via-m/Tests/file_s18. ---------------------------------------------------------------------- Comment By: Arjen de Rijke (arjenderijke) Date: 2009-09-25 10:10 Message: According to http://monetdb.cwi.nl/testing/projects/monetdb/Current/sql/.mTests103/GNU.64.64.d.0-Fedora10/src_test_Via-m/file_s18.out.00.html of today the problem still exists. But maybe that test is more complicated than the script i attached to this bugreport. To be precise, the problem occurs in test file_s17, that contains the call to a function. And because that function does not insert records into a table, the test file_s18 failes, because the table does not contain the records that are expected. ---------------------------------------------------------------------- Comment By: Niels Nes (nielsnes) Date: 2009-09-23 21:45 Message: fixed on current by martin ---------------------------------------------------------------------- Comment By: Stefan Manegold (stmane) Date: 2009-09-22 12:49 Message: Dead code elimination at work? Or: dead code elimination does (can?) not recognize that your function has a side effect, and hence skips the function call, since its result is not used? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=2864179&group_id=56967 ------------------------------------------------------------------------------ Come build with us!
