8.5.2 Bugs Fixed

• Memory manager: efficiency bug.
• library(structs): unsigned types, 64-bit issues.
• Prologbeans: Lists of integers with element values above 255 broke the communication between Java and SICStus.
• Closing a stream would sometimes hang due to a race condition on UNIX-like platforms. This was most likely to happen on MacOS X.
• set_stream_position/2 and seek/4 did not work on output streams.
• Multiple issues with absolute_file_name/3.
  • Option file_errors(fail) would sometimes report permission errors (SPIO_E_PERMISSION_ERROR) instead of silently failing.
  • Option file_errors(fail) now fails instead of raising an exception for file name domain errors like malformed file names and too many symbolic links (SPIO_E_INVALID_NAME).
  • Options access(execute) and access(search) now imply access(exist). This is similar to how access(read) works.
  • The undocumented internal option access(directory) was allowed. Use file_type(directory) instead.
• library(process): process_create/[2,3] now skips non-executable file and non-files if the File-argument can expand to more than one file. This is especially useful when using the symbolic name path/1 to specify a file.
• library(avl): Bug in avl_delete/4.
• library(random): Document and check validity of the random number generator state. Bug in random_numlist/4.
• get_atts/2: Could fail incorrectly.
• library(clpfd): A memory management problem. An integer overflow problem. Propagation bug in case/[3,4], affecting automaton/8 too.
• A problem with shared subterms in copying, asserting, collecting and throwing terms.
• The Prolog flag title was truncated on Windows spwin.exe.
• The spdet utility did not automatically add `.pl' and `.pro' extensions to file name arguments.
