To fix +this bug, SIGINJECT signal is not sent by child process but by control thread +in parent process; +- minor bug is fixed in data injection (POKE) that does not work as expected +when child process is protected by NRPROC. +* Thu Aug 26 2010 BERTRAND Joël rpl-4.0.18 (RPL/2) +- --enable-sysv-sems is added to configure script to use SystemV semaphores +functions instead of POSIX functions. This function is disabled or forced on +systems that does not provide correct POSIX or SysV semaphores subsystem; +- a dirty but not quick patch is written to workaround broken siginfo +structures. This patch has been successfully tested. It uses a segment of +shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process +(Unix PID); +- some OpenBSD's hacks are added; +- broken siginfo->si_pid field is now checked by configure script; +- SWI now sends SIGCONT to interrupted process to start interrupt without delay; +- random generator is cloned by SPAWN; +- in transliteration subroutine : '\r' is added after all '\n' in OS/2 port; +- getaddrinfo is hardcoded when host system does not provide getaddrinfo +or freeaddrinfo; +- RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable; +- major bug is fixed in CHR intrinsic when obtained character is not printable; +- Lapack is upgraded to 3.2.2; +- OS/2 (eComStation 2.0 with EMX 0.9d) support is added; +- TOKENIZE is now able to convert escape sequences; +- ATPOKE and CLRATPOKE new intrinsics are added; +- --enable-full-static configure flag is added.

When a global +variable was created and when a local variable existed with the same name, +computed address of global variable was wrong; +- src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3 +is forced in front of all libraries. +* Tue Jul 13 2010 BERTRAND Joël rpl-4.0.17 (RPL/2) +- BACKTRACE intrinsic is added; +- major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs +when this structure is included in IFERR/THEN/END structure and when an error is +caught; +- major bug is fixed in analyse() subroutine. When evaluation() returned error +in a compiled program, analyse() caught this error twice and randomly aborted +with a segmentation error; +- TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces; +- ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop +signals; +- memory leak is fixed in ROW+. It only occurs when a row is added to an empty +matrix. +* Thu Jun 24 2010 BERTRAND Joël rpl-4.0.16 (RPL/2) +- minor bug is fixed in evaluation() subroutine.

MEMLOCK forces a process to remain in memory +and to not use swap; +- major bug is fixed in sql support. SQL connections were closed in all chield +process; +- standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs +discovered in Solaris thread safe allocators (libmalloc and libumem) that +are first fit class allocators.
