382: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
383: - major bug is fixed in STD format (1E7 sq prints 1);
384: - major bug is fixed in READ intrinsic (socket). This bug was introduced
385: by a new feature in glibc.
386: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
387: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
388: "ALL" IMPLICIT when it runs in interactive mode;
389: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
390: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
391: to use SAVE to manipulate global variables;
392: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
393: subroutines;
394: - fix major memory access violation in evaluation subroutine. Only occurs
395: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
396: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
397: when X was a vector or a table.
398: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

421: segmentation fault;
422: - sqlite is upgraded to 3.7.4;
423: - OpenSSL is upgraded to 1.0.0c;
424: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);

426: - gnuplot is upgraded to 4.4.2 due to major bugs.
427: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
428: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
429: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
430: corruption. As internal memory management have been improved, a best fit
431: allocator like ptmalloc3 is not required anymore;
432: - gnuplot is upgraded to 4.4.1;
433: - deadlock is fixed in signal handlers: same mutex was used in standard
434: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
435: and signal handlers. A new signal handler specific mutex is added;
436: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
437: that has to be evaluated by ->NUM;
438: - rplfile build process is modify to be sure that rplfile is not modified
439: after rpl build stage (to be sure that rplfile checksum is not modified after

444: ABORT now works on eComStation;
445: - sqlite is upgraded to 3.7.2;
446: - bug is fixed in software interrupts. When both process have different PID,
447: parent process was not interrupted if it is not group master process. To fix
448: this bug, SIGINJECT signal is not sent by child process but by control thread
449: in parent process;
450: - minor bug is fixed in data injection (POKE) that does not work as expected
451: when child process is protected by NRPROC.
452: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
453: - --enable-sysv-sems is added to configure script to use SystemV semaphores
454: functions instead of POSIX functions. This function is disabled or forced on
455: systems that does not provide correct POSIX or SysV semaphores subsystem;
456: - a dirty but not quick patch is written to workaround broken siginfo
457: structures. This patch has been successfully tested. It uses a segment of
458: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
459: (Unix PID);
460: - some OpenBSD's hacks are added;
461: - broken siginfo->si_pid field is now checked by configure script;
462: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

479: Level 0 and 1 variables adresses were swapped when a global variable masked
480: a name of RPL/2 routine;
481: - major bug is fixed in global variable creation subroutine. When a global
482: variable was created and when a local variable existed with the same name,
483: computed address of global variable was wrong;
484: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
485: is forced in front of all libraries.
486: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
487: - BACKTRACE intrinsic is added;
488: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
489: when this structure is included in IFERR/THEN/END structure and when an error is
490: caught;
491: - major bug is fixed in analyse() subroutine. When evaluation() returned error
492: in a compiled program, analyse() caught this error twice and randomly aborted
493: with a segmentation error;
494: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
495: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
496: signals;
497: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
498: matrix.
499: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

517: format in FCH (file descriptor) and SCK (socket descriptor);
518: - debug routines are improved;
519: - PROCID is added;
520: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
521: and to not use swap;
522: - major bug is fixed in sql support. SQL connections were closed in all chield
523: process;
524: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
525: discovered in Solaris thread safe allocators (libmalloc and libumem) that
526: are first fit class allocators. Solaris libmtmalloc works better and is
527: a best fit class allocator but its performance is poor than ptmalloc3
528: performance;
529: - major bug is fixed in ROW+ intrinsic (new row was not added where it
530: should);
531: - minor bugs are fixed in interruptions.c (semaphores values when error is
532: caught);
533: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
534: created by SPAWN;
535: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute

544: information about shared variable was not copied to new processus structure;
545: - some little memory leaks are fixed in evaluation(), recherche_type() and
546: sequenceur(). They only occured when syntax error were caught;
547: - IMPLICIT causes execution error instead system error;
548: - Hurd support is improved but currently broken because Hurd does not support
549: SIG_INFO. Work in progress;
550: - OpenBSD specific support is removed from sources;
551: - support for Mac OS X and Windows/Cygwin is added.
552: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

591: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
592: - in formatted file, string format returned a variable length string even if
593: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
594: a variable length string and 'CHARACTER*(n)' a fixed length string;
595: - keyed access files support is added. Currently, only formatted files are
596: supported;
597: - direct access files support is added. Currenlty, these files can only be used
598: in formatted mode;
599: - virtual variables are now writte in UTF-8 and all special characters
600: in string are escaped;
601: - all formatted files are now converted into UTF-8;
602: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
603: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
604: each execution (md5 and sha1 sums) to enhance security. If one of these tools
605: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
606: on a non recoverable system error;
607: - openssl and sqlite3 libraries are added;
608: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
609: variable indicates RPL/2 root directory. If it is not set, root path
610: is given by configure script (d_exec_path);
611: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

643: list argument and inexistant elements).
644: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
645: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
646: signals sent to main process were not caught because DAEMON did not replace
647: old pid by new one;
648: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
649: evaluation when an error is reported from a subroutine in another subroutine.
650: For example, error was not caught in following program when it is executed with
651: -p option :
652: TEST << iferr TEST2 then end >>
653: TEST2 << 0 inv >>
654: - major bug is fixed in variable management. Some local variables were
655: seen as global ones;
656: - major bug is fixed in rplcore. Rplcore entered in dead lock when
657: script file contains a multibyte character;
658: - IN intrinsic is added;
659: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
660: returned false ;

668: - major bug is fixed in -A command line option (NULL character is missing);
669: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
670: made by blocks (1024 bytes). When an incomplete multibyte sequence is
671: encountered at end of block, subroutine aborts with an execution error;
672: - major bug is fixed in OPEN (TCP/IPv4 sockets).
673: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
674: - DISP now locks stdout;
675: - rpliconv is added to replace standard iconv provided by operating system.
676: Indeed, conversion between different encodages requires transliteration
677: that is not offered by some iconv utility;
678: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
679: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
680: not be found), SYSEVAL enters in a dead lock;
681: - fprintf is replaced by some functions that allow transliterations between
682: locales;
683: - '"' can now be used in strings ("\"");
684: - iconv is called with -c in preprocessor stage. It is done to write
685: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
686: - double free is fixed in liberation() (type SQL, only occurs when locale is
687: set);
688: - LOCALIZATION, UCASE and LCASE are added;

690: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
691: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
692: used in onLoading from shared library, USE was pushed on stack as algebraic
693: expression;
694: - libiconv is upgraded to 1.13.1;
695: - gnuplot is upgraded to 4.2.6;
696: - gsl is upgraded to 1.13.
697: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
698: - pipe() is overwritten by a macro to avoid a system error. Communication
699: between process are done with pipes and these pipes are managed by a
700: specific asynchrone thread. If a script try to create more threads than
701: management thread can destroy, you can quickly achieve maximum number of
702: opened files and pipe() shall return a system error. This macro tries to create
703: pipes. If pipe() function returns an error, macro waits and retries. If
704: number of retries is greater than a hardcoded value, macro returns an error;
705: - major bug (deadlock) is fixed in process and thread management. I hope
706: this bug shall be the last one;
707: - major bug is fixed in DET intrinsic (determinant was computed without LU
708: diagonalization);

713: - all process management is rewritten to avoid usage of defunct process
714: or thread number;
715: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
716: was called before a pending interruption5 (SIGFSTOP), signal handler uses
717: a freed semaphore and corrupts heap;
718: - CLRERR is added to erase previous errors;
719: - ERRN and ERRM return exception message and number;
720: - major bug is fixed in interruptions.c. All signal are now bufferised
721: when semaphore_liste_threads is null to avoid deadlock. This bug only
722: occured when STOP was sent to a dying thread or process (when this thread or
723: process was running retrait_thread());
724: - matrix rank is computed before matrix inversion;
725: - file locks are added to stdin and stdout. stderr is not locked because
726: all messages written by signal handlers are sent to stderr;
727: - configure.in script is modified to test gcc version and avoid a bug in

801: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
802: process is killed;
803: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
804: know typeof() intrinsic function. This function is not standard but exists
805: under Sun Studio, gcc, and maybe some others compilers. If this function does

870: SQLQUERY. With all new programs, you can open a real connection to databases;
871: - NRPROC is added. This new intrinsic is used to catch error from child
872: process. Without NRPROC, any errors returned by child process cause
873: main process to abort;
874: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
875: starts a new process). There are no mutexes in RPL/2 because all spawned process

1172: - external wrapper (rplplot) is written to force usage of gnuplot provided
1173: by RPL/2 if it is built during build process. If this build does not exist,
1174: it tries to launch regular gnuplot;
1175: - gnuplot is added to source tree to avoid some trouble between preinstalled
1176: gnuplot and release used by RPL/2. This addition to source tree is

1183: not writable;
1184: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1185: error scrutation.

1230: - variable management routines have been rewritten. The new ones are
1231: uncompatible with the old ones. Before these changes, a local variable
1232: was exported to a child subroutine, but cannot be modified into this
1233: child subroutine. Now, a local variable is accessible only in its subroutine;
1234: - SAVE intrinsic is added to manipulate global variables;

1552: (less parenthesis);
1553: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1554: on Debian distribution, but since cpp is in the default path, RPL/2 works
1555: fine...);
1556: - NOT is not correctly formatted in formateur.c:
1557: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1558: with a NOTZ function !
1559: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1560: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1561: if the main loop is in a program;
1562: - RPL/2 is tested with efence and valgrind;
1563: - configure.in script is modified;
1564: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1565: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1566: another gcc bug...
1567: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)
1568: - EXIT is fixed. Now, it is possible to use EXIT in an expression when the
1569: main loop is in a program;

1613: { "automatic" nb_of_levels }
1614: { "discrete" l1 l2 l3 ... }
1615: { "incremental" start incr }
1616: { "incremental" start incr end }
1617: { "automatic" } (default);

1625: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1626: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1627: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1644: - SCLS is added;
1645: - DRWS now uses COLS to draw 2D graphics;
1646: - PPAR and SPAR are written. SPAR returns a list that contains the
1647: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1648: statistical variable, or "DISABLED" if its type is not one of the type of
1649: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1650: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1651: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1652: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1653: disabled. Arguments of EXTERNAL are case sensitive because the external
1654: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1655: of known external functions but add the new list to the last. { "all" }
1656: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1657: external names of the known functions;
1658: - mkrplso.in is modified.
1659: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1660: - vim syntax file is upgraded;
1661: - a minor mistake is fixed in recherche_instruction_suivante();
1662: - some minor memory leaks are fixed in recherche_type() function. They only

1671: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1672: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1673: VISIT does not find a name in level 1;
1674: - configure.in script is modified to add a new test (--enable-debug
1675: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1676: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1677: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1678: 'MATRIX' { 2 2 3 } GETR;
1679: - LOGSCALE intrinsic is improved and now, it can be used as
1680: { "main" "auxiliary" X Y } LOGSCALE;
1681: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1682: same than AXES:
1683: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1684: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1685: { { -10 10 } "automatic" } SCALE.
1686: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1687: because it changes only the dimension of the screen. To have a logarithmic
1688: scale, you must use LOGSCALE intrinsic:
1689: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1690: screen on second scale;
1691: - { X X } autoscale and { Y Y } logscale are now invalid;
1692: - *D is added (depth multiplication, for 3D graphics);
1693: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1694: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1695: - a major bug is fixed in GETI instrinsic when it is used with a name
1696: that contains a matrix or a vector (bad upper bounds conditions in
1697: incrementation);
1698: - DISP intrinsic now uses the 33-th flag. When it is not set
1699: (default), a final carriage return is sent to the terminal;
1700: - AXES intrinsic only takes a list that can contains the keywork
1701: "main" or "auxiliary". Before this modification, this keyword was in
1702: the first stack level;
1703: - vim syntax file is upgraded;
1704: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1705: option;
1706: - LAST is now disabled in the main loop of INT intrinsic;
1707: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1708: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1709: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1710: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1711: in 0);
1712: - LAST is disabled in the main loop of DRAW intrinsic;
1713: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1714: evaluation of an equation, the system stack is returned corrupted to the
1715: sequencer;
1716: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1717: of a loop are not integer or real.
1718: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1719: - the compilation stage aborts with an error message when two definitions

1726: - Makefile.am's and configure.in scripts are improved.
1727: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1728: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1729: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1730: the boxwidth, 1 by default);
1731: - recherche_type() is rewritten to be faster;
1732: - gsl is upgraded (release 1.3);
1733: - ncurses is upgraded and patched (release 5.3);

1747: - vim syntax file is improved;
1748: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1749: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1750: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1751: is a quick and dirty workaround...);
1752: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1753: - rplconvert is improved.
