172: by a new feature in glibc.
173: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
174: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
175: "ALL" IMPLICIT when it runs in interactive mode;
176: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
177: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
178: to use SAVE to manipulate global variables;
179: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
180: subroutines;
181: - fix major memory access violation in evaluation subroutine. Only occurs
182: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
183: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
184: when X was a vector or a table.

215: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
216: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
217: corruption. As internal memory management have been improved, a best fit
218: allocator like ptmalloc3 is not required anymore;
219: - gnuplot is upgraded to 4.4.1;
220: - deadlock is fixed in signal handlers: same mutex was used in standard
221: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
222: and signal handlers. A new signal handler specific mutex is added;
223: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
224: that has to be evaluated by ->NUM;
225: - rplfile build process is modify to be sure that rplfile is not modified
226: after rpl build stage (to be sure that rplfile checksum is not modified after

234: parent process was not interrupted if it is not group master process. To fix
235: this bug, SIGINJECT signal is not sent by child process but by control thread
236: in parent process;
237: - minor bug is fixed in data injection (POKE) that does not work as expected
238: when child process is protected by NRPROC.
239: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
240: - --enable-sysv-sems is added to configure script to use SystemV semaphores
241: functions instead of POSIX functions. This function is disabled or forced on
242: systems that does not provide correct POSIX or SysV semaphores subsystem;
243: - a dirty but not quick patch is written to workaround broken siginfo
244: structures. This patch has been successfully tested. It uses a segment of
245: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
246: (Unix PID);
247: - some OpenBSD's hacks are added;
248: - broken siginfo->si_pid field is now checked by configure script;
249: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

266: Level 0 and 1 variables adresses were swapped when a global variable masked
267: a name of RPL/2 routine;
268: - major bug is fixed in global variable creation subroutine. When a global
269: variable was created and when a local variable existed with the same name,
270: computed address of global variable was wrong;
271: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
272: is forced in front of all libraries.

274: - BACKTRACE intrinsic is added;
275: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
276: when this structure is included in IFERR/THEN/END structure and when an error is
277: caught;
278: - major bug is fixed in analyse() subroutine. When evaluation() returned error
279: in a compiled program, analyse() caught this error twice and randomly aborted
280: with a segmentation error;
281: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
282: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
283: signals;
284: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
285: matrix.
286: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

296: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
297: linux (false mremap() prototype);
298: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.

304: format in FCH (file descriptor) and SCK (socket descriptor);
305: - debug routines are improved;
306: - PROCID is added;
307: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
308: and to not use swap;
309: - major bug is fixed in sql support. SQL connections were closed in all chield
310: process;
311: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
312: discovered in Solaris thread safe allocators (libmalloc and libumem) that
313: are first fit class allocators. Solaris libmtmalloc works better and is
314: a best fit class allocator but its performance is poor than ptmalloc3
315: performance;
316: - major bug is fixed in ROW+ intrinsic (new row was not added where it
317: should);
318: - minor bugs are fixed in interruptions.c (semaphores values when error is
319: caught);
320: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
321: created by SPAWN;

331: information about shared variable was not copied to new processus structure;
332: - some little memory leaks are fixed in evaluation(), recherche_type() and
333: sequenceur(). They only occured when syntax error were caught;
334: - IMPLICIT causes execution error instead system error;

390: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
391: each execution (md5 and sha1 sums) to enhance security. If one of these tools
392: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
393: on a non recoverable system error;
394: - openssl and sqlite3 libraries are added;
395: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
396: variable indicates RPL/2 root directory. If it is not set, root path
397: is given by configure script (d_exec_path);
398: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
399: - configure.in and makefile.am's are modified to add Cygwin support. Interix

405: fraction intead real one;
406: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
407: - Makefile.am are modified to authorize parallel builds;
408: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
409: and writes warning to standard output;
410: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)
411: - escape codes are now converted in formateur(), not in recherche_type() to
412: avoid a minor bug in EDIT and VISIT intrinsics;

414: - file-5.03 is patched to avoid bus error on systems that require memory
415: alignment;
416: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
417: were able to be avoided by evaluation routine.

426: - TRIM, REPL and TOKENIZE are added;
427: - sockets options are now set before bind();
428: - shutdown() is added to all connected sockets;
429: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
430: list argument and inexistant elements).
431: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
432: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
433: signals sent to main process were not caught because DAEMON did not replace
434: old pid by new one;
435: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
436: evaluation when an error is reported from a subroutine in another subroutine.
437: For example, error was not caught in following program when it is executed with
438: -p option :
439: TEST << iferr TEST2 then end >>
440: TEST2 << 0 inv >>
441: - major bug is fixed in variable management. Some local variables were
442: seen as global ones;
443: - major bug is fixed in rplcore. Rplcore entered in dead lock when
444: script file contains a multibyte character;
445: - IN intrinsic is added;
446: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
447: returned false ;
448: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
449: programs;
450: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
451: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
452: strings were never closed;
453: - some bugs have been fixed in file management;
454: - RPL/2 can now be run on EBCDIC systems (OS/390);
455: - major bug is fixed in -A command line option (NULL character is missing);
456: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
457: made by blocks (1024 bytes). When an incomplete multibyte sequence is
458: encountered at end of block, subroutine aborts with an execution error;
459: - major bug is fixed in OPEN (TCP/IPv4 sockets).
460: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
461: - DISP now locks stdout;
462: - rpliconv is added to replace standard iconv provided by operating system.
463: Indeed, conversion between different encodages requires transliteration
464: that is not offered by some iconv utility;
465: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
466: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
467: not be found), SYSEVAL enters in a dead lock;
468: - fprintf is replaced by some functions that allow transliterations between
469: locales;
470: - '"' can now be used in strings ("\"");
471: - iconv is called with -c in preprocessor stage. It is done to write
472: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
473: - double free is fixed in liberation() (type SQL, only occurs when locale is
474: set);
475: - LOCALIZATION, UCASE and LCASE are added;
476: - major bug is fixed in EXIT intrinsic that was able to return a false
477: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
478: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
479: used in onLoading from shared library, USE was pushed on stack as algebraic
480: expression;
481: - libiconv is upgraded to 1.13.1;
482: - gnuplot is upgraded to 4.2.6;
483: - gsl is upgraded to 1.13.
484: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
485: - pipe() is overwritten by a macro to avoid a system error. Communication
486: between process are done with pipes and these pipes are managed by a
487: specific asynchrone thread. If a script try to create more threads than
488: management thread can destroy, you can quickly achieve maximum number of
489: opened files and pipe() shall return a system error. This macro tries to create
490: pipes. If pipe() function returns an error, macro waits and retries. If
491: number of retries is greater than a hardcoded value, macro returns an error;
492: - major bug (deadlock) is fixed in process and thread management. I hope
493: this bug shall be the last one;
494: - major bug is fixed in DET intrinsic (determinant was computed without LU
495: diagonalization);
496: - SWAPCNTXT is added;
497: - minor bug is fixed in Makefile.am (licences rule).
498: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
499: - some bugfixes are added in process management;
500: - all process management is rewritten to avoid usage of defunct process
501: or thread number;
502: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
503: was called before a pending interruption5 (SIGFSTOP), signal handler uses
504: a freed semaphore and corrupts heap;
505: - CLRERR is added to erase previous errors;
506: - ERRN and ERRM return exception message and number;
507: - major bug is fixed in interruptions.c. All signal are now bufferised
508: when semaphore_liste_threads is null to avoid deadlock. This bug only
509: occured when STOP was sent to a dying thread or process (when this thread or
510: process was running retrait_thread());
511: - matrix rank is computed before matrix inversion;
512: - file locks are added to stdin and stdout. stderr is not locked because
513: all messages written by signal handlers are sent to stderr;
514: - configure.in script is modified to test gcc version and avoid a bug in
515: gcc older than 4.4;
516: - some benchmarks have been done :

588: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
589: process is killed;
590: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
591: know typeof() intrinsic function. This function is not standard but exists
592: under Sun Studio, gcc, and maybe some others compilers. If this function does
593: not exist on your compiler, you can change its definition by old one in

617: deadlock when a huge amount of threads is launched);
618: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
619: arguments types are unsupported;
620: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
621: data are buffered. PLOT is used to draw these objects.);

635: static variable that is shared by multiple threads;
636: - '->' intrinsic is improved. All object copies have been avoided;
637: - -n flag is added to catch HUP signal. stderr and stdout are redirected
638: to a file, stdin is redirected to /dev/null when control process is killed;
639: - a mutex is added to each object (before this modification,
640: RPL/2 used a global mutex and performances in multithreaded programs were very
641: poor.);

656: that all programs that worked with old SQL intrinsic can now work with
657: SQLQUERY. With all new programs, you can open a real connection to databases;
658: - NRPROC is added. This new intrinsic is used to catch error from child
659: process. Without NRPROC, any errors returned by child process cause
660: main process to abort;
661: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
662: starts a new process). There are no mutexes in RPL/2 because all spawned process
663: use specific context. Nevertheless, shared variables and associated mutexes
664: should be added;

750: - FUSE, RFUSE and CLRFUSE have been added;
751: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
752: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
753: workaround for this major bug. Nevertheless, all others capabilities seems to
754: work fine;

813: - -p option is added. With this option, all scripts are compiled before
814: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
815: 40% faster;
816: - read and write operations in pipe() are rewritten to be sure that such
817: operations are atomic;
818: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1014: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1015: versions of PROTECT and UNPROTECT that only deal with global variables
1016: (see RCL/SAVE);
1017: - variable management routines have been rewritten. The new ones are
1018: uncompatible with the old ones. Before these changes, a local variable
1019: was exported to a child subroutine, but cannot be modified into this
1020: child subroutine. Now, a local variable is accessible only in its subroutine;
1021: - SAVE intrinsic is added to manipulate global variables;

1059: perform a better task synchronization;
1060: - some bugs introduced by locales specific compilations are fixed;
1061: - major memory corruption is fixed in DEPND;
1062: - HELP intrinsic is modified to print a classified output.

1342: fine...);
1343: - NOT is not correctly formatted in formateur.c:
1344: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1345: with a NOTZ function !
1346: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1349: - RPL/2 is tested with efence and valgrind;
1350: - configure.in script is modified;
1351: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1412: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1413: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1414: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1415: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1431: - SCLS is added;
1432: - DRWS now uses COLS to draw 2D graphics;
1433: - PPAR and SPAR are written. SPAR returns a list that contains the
1434: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1435: statistical variable, or "DISABLED" if its type is not one of the type of
1436: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1437: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1438: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1439: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1440: disabled. Arguments of EXTERNAL are case sensitive because the external
1441: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1442: of known external functions but add the new list to the last. { "all" }
1443: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1444: external names of the known functions;
1445: - mkrplso.in is modified.
1446: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1447: - vim syntax file is upgraded;
1448: - a minor mistake is fixed in recherche_instruction_suivante();

1459: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1460: VISIT does not find a name in level 1;
1461: - configure.in script is modified to add a new test (--enable-debug
1462: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1463: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1464: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1465: 'MATRIX' { 2 2 3 } GETR;
1466: - LOGSCALE intrinsic is improved and now, it can be used as
1467: { "main" "auxiliary" X Y } LOGSCALE;
1468: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1469: same than AXES:
1470: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1471: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1472: { { -10 10 } "automatic" } SCALE.
1473: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1474: because it changes only the dimension of the screen. To have a logarithmic
1475: scale, you must use LOGSCALE intrinsic:
1476: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1477: screen on second scale;
1478: - { X X } autoscale and { Y Y } logscale are now invalid;
1479: - *D is added (depth multiplication, for 3D graphics);
1480: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1481: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1482: - a major bug is fixed in GETI instrinsic when it is used with a name
1483: that contains a matrix or a vector (bad upper bounds conditions in
1484: incrementation);
1485: - DISP intrinsic now uses the 33-th flag. When it is not set
1486: (default), a final carriage return is sent to the terminal;
1487: - AXES intrinsic only takes a list that can contains the keywork
1488: "main" or "auxiliary". Before this modification, this keyword was in
1489: the first stack level;
1490: - vim syntax file is upgraded;
1491: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1492: option;
1493: - LAST is now disabled in the main loop of INT intrinsic;
1494: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1495: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1496: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1497: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1498: in 0);
1499: - LAST is disabled in the main loop of DRAW intrinsic;
1500: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1501: evaluation of an equation, the system stack is returned corrupted to the
1502: sequencer;
1503: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1504: of a loop are not integer or real.
1505: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1506: - the compilation stage aborts with an error message when two definitions
1507: have the same name. To improve the compilation() subroutine, I have to
1508: add some tests in gestion_variables.c;
1509: - recherche_type() subroutine ad some other connex subroutines are improved.
1510: Now, some syntax errors about object are caught and do not perform sequencer
