|
- by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and |
|
"ALL" IMPLICIT when it runs in interactive mode; |
|
- when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used |
|
to create or modify a global variable. Now, with "NONE" IMPLICIT, you have |
|
to use SAVE to manipulate global variables; |
|
- replace erroneous TAB by TBL in evaluation() and formateur_fichier() |
|
subroutines; |
|
- fix major memory access violation in evaluation subroutine. Only occurs |
|
when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds; |
|
- fix major bug in evaluation subroutine. 'X(i)' returns execution error |
|
when X was a vector or a table. |

|
- Gnuplot is upgraded; |
|
- flag 34 is now used to enable or disable control character evaluation; |
|
- major bug is fixed in P->R intrinsic function when argument type is |
|
complex and degree mode is set; |
|
- L->T and T->L are added; |
|
- OLD filetype is fixed; |
|
- FLOW socket support is added; |
|
- FLOW sequential files are added; |
|
- new escape sequence is added to handle flow files (\x + hexadecimal code). |
|
Known escape sequences are \", \b, \n, \t, \x?? and \\. |

* Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2) |
|
- Ncurses is upgraded to 5.8; |
|
- ALARM is fixed by filling isdst field; |
|
- catch ECONNRESET in write intrinsic to return an execution error instead of |
|
system one; |
|
- fix a typo in HELP intrinsic; |
|
- Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2; |
|
- Lapack is upgraded to 3.3.0; |
|
- libmtmalloc is now default Solaris allocator; |
|
- ncurses is upgraded; |
|
- regression introduced by 4.0.19 is fixed in signal management. |
|
Interruption1() could be called from itself and raises bus error (on sparc) or |
|
segmentation fault; |
|
- sqlite is upgraded to 3.7.4; |
|
- OpenSSL is upgraded to 1.0.0c; |
|
- syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore); |
|
- characters are tested in recherche_type() to avoid names like '12+'; |
|
- gnuplot is upgraded to 4.4.2 due to major bugs. |
|
* Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2) |
|
- due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed. |
|
Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap |
|
corruption. As internal memory management have been improved, a best fit |
|
allocator like ptmalloc3 is not required anymore; |
|
- gnuplot is upgraded to 4.4.1; |
|
- deadlock is fixed in signal handlers: same mutex was used in standard |
|
subroutines (without protected sections by sigprocmask() or pthread_sigmask()) |
|
and signal handlers. A new signal handler specific mutex is added; |
|
- minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function |
|
that has to be evaluated by ->NUM; |
|
- rplfile build process is modify to be sure that rplfile is not modified |
|
after rpl build stage (to be sure that rplfile checksum is not modified after |
|
rpl compilation); |
|
- AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan, |
|
modified to remove yacc code and renamed; |
|
- some workarounds have been written to not use buggy klibc SystemV IPCS. |
|
ABORT now works on eComStation; |
|
- sqlite is upgraded to 3.7.2; |
|
- bug is fixed in software interrupts. When both process have different PID, |
|
parent process was not interrupted if it is not group master process. 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@systella.fr> 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; |
- SWI now sends SIGCONT to interrupted process to start interrupt without delay; |
- random generator is cloned by SPAWN; |
- random generator is cloned by SPAWN; |
- in transliteration subroutine : '\r' is added after all '\n' in OS/2 port; |
