13.28.2 Other Changes

• The sicstus command line flag -l can now be specified more than once and will load the files in the order specified.
• The low-level memory allocator has been re-implemented. The new implementation should be faster and avoids some poor worst-case behavior.
• The memory-allocation hook SP_set_memalloc_hooks() has been deprecated and is, by default, no longer available. Please contact SICStus Support if this is a problem for you.
• Improved performance of library(timeout).
• A performance problem when using the Linux performance monitoring tool perf has been fixed.
• Stack shifting and garbage collection policies have been adjusted, and the gc_margin Prolog flag has been given a more dynamic meaning.
• Changes to the testing framework, library(plunit):
  • - It is now possible to programmatically obtain the number of successful, skipped, and failed tests.
  • - The number of skipped tests, i.e. where condition/1 is false, is reported when the tests have run.
  • - Multiple occurrences of some options, like true/1, are combined. It used to quietly discard all but one.
  • - Test options are more thoroughly checked, and incompatible options are reported.
  • - Problems with options, and with test initialization, are now reported and counted as a failure also when the test is run. It used to print a warning but not be counted towards the number of failed tests.
  • - A test body that succeeds while leaving as choice point will now be treated as a test failure, unless nondet is specified. This was always the documented behavior, but it used to only print a warning.
• The Java code in libraries and examples has been cleaned up to avoid warnings and use of deprecated features.
• The Java code in se/sics/jasper/ has been changed to use generic types. This may trigger some Java compiler warnings for existing code. Code that use ‘raw’ types may need to be updated, e.g. changing Map to Map<String,Term> for the maps that specify variable bindings.
