380: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
381: "ALL" IMPLICIT when it runs in interactive mode;
382: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
383: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
384: to use SAVE to manipulate global variables;
385: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
386: subroutines;
387: - fix major memory access violation in evaluation subroutine. Only occurs
388: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
389: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
390: when X was a vector or a table.
391: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

411: - ncurses is upgraded;
412: - regression introduced by 4.0.19 is fixed in signal management.
413: Interruption1() could be called from itself and raises bus error (on sparc) or
414: segmentation fault;
415: - sqlite is upgraded to 3.7.4;
416: - OpenSSL is upgraded to 1.0.0c;
417: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);

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

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

463: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
464: - TOKENIZE is now able to convert escape sequences;
465: - ATPOKE and CLRATPOKE new intrinsics are added;

467: postgresql libraries are statically linked in rpl executable;
468: - units Makefile is modified to avoid readline and ncurses usages;
469: - sqlite is upgraded to 3.7.0.1;
470: - units is upgraded to 1.88;
471: - another major bug is fixed in the same variable creation subroutine.
472: Level 0 and 1 variables adresses were swapped when a global variable masked
473: a name of RPL/2 routine;
474: - major bug is fixed in global variable creation subroutine. When a global
475: variable was created and when a local variable existed with the same name,
476: computed address of global variable was wrong;
477: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
478: is forced in front of all libraries.
479: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
480: - BACKTRACE intrinsic is added;
481: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
482: when this structure is included in IFERR/THEN/END structure and when an error is
483: caught;
484: - major bug is fixed in analyse() subroutine. When evaluation() returned error
485: in a compiled program, analyse() caught this error twice and randomly aborted
486: with a segmentation error;
487: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
488: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
489: signals;
490: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
491: matrix.
492: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

502: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
503: linux (false mremap() prototype);
504: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
505: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
506: - all '-' are replaced by '_' in random generator list;

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

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

577: subroutine;
578: - table variable can now be sorted by SORT;
579: - some regressions between libtool 1.x and 2.x are fixed by workarouds in
580: Makefiles;

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

636: list argument and inexistant elements).
637: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
638: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
639: signals sent to main process were not caught because DAEMON did not replace
640: old pid by new one;
641: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
642: evaluation when an error is reported from a subroutine in another subroutine.
643: For example, error was not caught in following program when it is executed with
644: -p option :
645: TEST << iferr TEST2 then end >>
646: TEST2 << 0 inv >>
647: - major bug is fixed in variable management. Some local variables were
648: seen as global ones;
649: - major bug is fixed in rplcore. Rplcore entered in dead lock when
650: script file contains a multibyte character;
651: - IN intrinsic is added;
652: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
653: returned false ;
654: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
655: programs;
656: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
657: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
658: strings were never closed;
659: - some bugs have been fixed in file management;

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

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

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

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

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

1149: - MEM does not report static variable sizes;
1150: - minor bug is fixed in HELP intrinsic. When the last instruction was not
1151: known, HELP function was pushed in operational stack. HELP did not work
1152: when there were space on input line.
1153: * Mon May 28 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8v (RPL/2)

1164: - HELP function is rewritten to be more friendly (a la OpenVMS);
1165: - external wrapper (rplplot) is written to force usage of gnuplot provided
1166: by RPL/2 if it is built during build process. If this build does not exist,
1167: it tries to launch regular gnuplot;
1168: - gnuplot is added to source tree to avoid some trouble between preinstalled
1169: gnuplot and release used by RPL/2. This addition to source tree is
1170: required by some incompatibility between gnuplot releases;

1176: not writable;
1177: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1178: error scrutation.

1220: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1221: versions of PROTECT and UNPROTECT that only deal with global variables
1222: (see RCL/SAVE);
1223: - variable management routines have been rewritten. The new ones are
1224: uncompatible with the old ones. Before these changes, a local variable
1225: was exported to a child subroutine, but cannot be modified into this
1226: child subroutine. Now, a local variable is accessible only in its subroutine;
1227: - SAVE intrinsic is added to manipulate global variables;

1545: (less parenthesis);
1546: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1547: on Debian distribution, but since cpp is in the default path, RPL/2 works
1548: fine...);
1549: - NOT is not correctly formatted in formateur.c:
1550: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1551: with a NOTZ function !
1552: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1553: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1554: if the main loop is in a program;
1555: - RPL/2 is tested with efence and valgrind;
1556: - configure.in script is modified;
1557: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1558: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1606: { "automatic" nb_of_levels }
1607: { "discrete" l1 l2 l3 ... }
1608: { "incremental" start incr }
1609: { "incremental" start incr end }

1618: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1619: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1620: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1637: - SCLS is added;
1638: - DRWS now uses COLS to draw 2D graphics;
1639: - PPAR and SPAR are written. SPAR returns a list that contains the
1640: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1641: statistical variable, or "DISABLED" if its type is not one of the type of
1642: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1643: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1644: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1645: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1646: disabled. Arguments of EXTERNAL are case sensitive because the external
1647: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1648: of known external functions but add the new list to the last. { "all" }
1649: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1650: external names of the known functions;
1651: - mkrplso.in is modified.
1652: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1653: - vim syntax file is upgraded;
1654: - a minor mistake is fixed in recherche_instruction_suivante();

1664: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1665: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1666: VISIT does not find a name in level 1;
1667: - configure.in script is modified to add a new test (--enable-debug
1668: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1669: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1670: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1671: 'MATRIX' { 2 2 3 } GETR;
1672: - LOGSCALE intrinsic is improved and now, it can be used as
1673: { "main" "auxiliary" X Y } LOGSCALE;
1674: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1675: same than AXES:
1676: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1677: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1678: { { -10 10 } "automatic" } SCALE.
1679: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1680: because it changes only the dimension of the screen. To have a logarithmic
1681: scale, you must use LOGSCALE intrinsic:
1682: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1683: screen on second scale;
1684: - { X X } autoscale and { Y Y } logscale are now invalid;
1685: - *D is added (depth multiplication, for 3D graphics);
1686: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1687: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1688: - a major bug is fixed in GETI instrinsic when it is used with a name
1689: that contains a matrix or a vector (bad upper bounds conditions in
1690: incrementation);
1691: - DISP intrinsic now uses the 33-th flag. When it is not set
1692: (default), a final carriage return is sent to the terminal;
1693: - AXES intrinsic only takes a list that can contains the keywork
1694: "main" or "auxiliary". Before this modification, this keyword was in
1695: the first stack level;
1696: - vim syntax file is upgraded;
1697: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1698: option;
1699: - LAST is now disabled in the main loop of INT intrinsic;
1700: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1701: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1702: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1703: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1704: in 0);
1705: - LAST is disabled in the main loop of DRAW intrinsic;
1706: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1707: evaluation of an equation, the system stack is returned corrupted to the
1708: sequencer;
1709: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1710: of a loop are not integer or real.
1711: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1719: - Makefile.am's and configure.in scripts are improved.
1720: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1721: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1722: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1742: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1743: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1744: is a quick and dirty workaround...);
1745: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1746: - rplconvert is improved.

1855: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1856: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1857: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1858: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1859:
