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

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

238: parent process was not interrupted if it is not group master process. To fix
239: this bug, SIGINJECT signal is not sent by child process but by control thread
240: in parent process;
241: - minor bug is fixed in data injection (POKE) that does not work as expected
242: when child process is protected by NRPROC.
243: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
244: - --enable-sysv-sems is added to configure script to use SystemV semaphores
245: functions instead of POSIX functions. This function is disabled or forced on
246: systems that does not provide correct POSIX or SysV semaphores subsystem;
247: - a dirty but not quick patch is written to workaround broken siginfo
248: structures. This patch has been successfully tested. It uses a segment of
249: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
250: (Unix PID);
251: - some OpenBSD's hacks are added;
252: - broken siginfo->si_pid field is now checked by configure script;

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

278: - BACKTRACE intrinsic is added;
279: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
280: when this structure is included in IFERR/THEN/END structure and when an error is
281: caught;
282: - major bug is fixed in analyse() subroutine. When evaluation() returned error
283: in a compiled program, analyse() caught this error twice and randomly aborted
284: with a segmentation error;
285: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
286: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
287: signals;
288: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
289: matrix.

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

391: in string are escaped;
392: - all formatted files are now converted into UTF-8;
393: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
394: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
395: each execution (md5 and sha1 sums) to enhance security. If one of these tools
396: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
397: on a non recoverable system error;
398: - openssl and sqlite3 libraries are added;
399: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
400: variable indicates RPL/2 root directory. If it is not set, root path
401: is given by configure script (d_exec_path);
402: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
403: - configure.in and makefile.am's are modified to add Cygwin support. Interix

410: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
411: - Makefile.am are modified to authorize parallel builds;
412: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer

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

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

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

621: deadlock when a huge amount of threads is launched);
622: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
623: arguments types are unsupported;
624: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

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

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

807: before starting interrupt evaluation;
808: - -f parameter is added when iconv is called;
809: - as old file program was bugged, a new option is added to configure script.
810: When configure is called with --disable-encoding-autodetection, make does not
811: try to detect source encoding. Please, do not use if RPL/2 can be built
812: without this option !
813: - new garbage collector (and more efficient) is written;

817: - -p option is added. With this option, all scripts are compiled before
818: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
819: 40% faster;
820: - read and write operations in pipe() are rewritten to be sure that such
821: operations are atomic;
822: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1016: With STATIC, next variables created by '->' are static;
1017: - PROTECT and UNPROTECT are added to protect variables against write
1018: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1019: versions of PROTECT and UNPROTECT that only deal with global variables
1020: (see RCL/SAVE);
1021: - variable management routines have been rewritten. The new ones are
1022: uncompatible with the old ones. Before these changes, a local variable
1023: was exported to a child subroutine, but cannot be modified into this
1024: child subroutine. Now, a local variable is accessible only in its subroutine;
1025: - SAVE intrinsic is added to manipulate global variables;

1346: fine...);
1347: - NOT is not correctly formatted in formateur.c:
1348: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1349: with a NOTZ function !
1350: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1353: - RPL/2 is tested with efence and valgrind;
1354: - configure.in script is modified;
1355: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1416: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1417: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1418: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1435: - SCLS is added;
1436: - DRWS now uses COLS to draw 2D graphics;
1437: - PPAR and SPAR are written. SPAR returns a list that contains the
1438: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1439: statistical variable, or "DISABLED" if its type is not one of the type of
1440: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1441: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1442: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1443: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1444: disabled. Arguments of EXTERNAL are case sensitive because the external
1445: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1446: of known external functions but add the new list to the last. { "all" }
1447: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1448: external names of the known functions;
1449: - mkrplso.in is modified.
1450: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1451: - vim syntax file is upgraded;
1452: - a minor mistake is fixed in recherche_instruction_suivante();

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