373: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
374: "ALL" IMPLICIT when it runs in interactive mode;
375: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
376: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
377: to use SAVE to manipulate global variables;

413: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
414: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
415: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
416: corruption. As internal memory management have been improved, a best fit
417: allocator like ptmalloc3 is not required anymore;
418: - gnuplot is upgraded to 4.4.1;
419: - deadlock is fixed in signal handlers: same mutex was used in standard
420: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
421: and signal handlers. A new signal handler specific mutex is added;
422: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
423: that has to be evaluated by ->NUM;
424: - rplfile build process is modify to be sure that rplfile is not modified
425: after rpl build stage (to be sure that rplfile checksum is not modified after

434: this bug, SIGINJECT signal is not sent by child process but by control thread
435: in parent process;
436: - minor bug is fixed in data injection (POKE) that does not work as expected
437: when child process is protected by NRPROC.
438: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
439: - --enable-sysv-sems is added to configure script to use SystemV semaphores
440: functions instead of POSIX functions. This function is disabled or forced on
441: systems that does not provide correct POSIX or SysV semaphores subsystem;
442: - a dirty but not quick patch is written to workaround broken siginfo
443: structures. This patch has been successfully tested. It uses a segment of
444: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
445: (Unix PID);
446: - some OpenBSD's hacks are added;
447: - broken siginfo->si_pid field is now checked by configure script;

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

473: - BACKTRACE intrinsic is added;
474: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
475: when this structure is included in IFERR/THEN/END structure and when an error is
476: caught;
477: - major bug is fixed in analyse() subroutine. When evaluation() returned error
478: in a compiled program, analyse() caught this error twice and randomly aborted
479: with a segmentation error;
480: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
481: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
482: signals;
483: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
484: matrix.

506: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
507: and to not use swap;
508: - major bug is fixed in sql support. SQL connections were closed in all chield
509: process;
510: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
511: discovered in Solaris thread safe allocators (libmalloc and libumem) that
512: are first fit class allocators. Solaris libmtmalloc works better and is
513: a best fit class allocator but its performance is poor than ptmalloc3
514: performance;

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

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

630: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
631: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
632: signals sent to main process were not caught because DAEMON did not replace
633: old pid by new one;
634: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
635: evaluation when an error is reported from a subroutine in another subroutine.
636: For example, error was not caught in following program when it is executed with
637: -p option :
638: TEST << iferr TEST2 then end >>
639: TEST2 << 0 inv >>
640: - major bug is fixed in variable management. Some local variables were
641: seen as global ones;
642: - major bug is fixed in rplcore. Rplcore entered in dead lock when
643: script file contains a multibyte character;
644: - IN intrinsic is added;
645: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
646: returned false ;

654: - major bug is fixed in -A command line option (NULL character is missing);
655: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
656: made by blocks (1024 bytes). When an incomplete multibyte sequence is
657: encountered at end of block, subroutine aborts with an execution error;
658: - major bug is fixed in OPEN (TCP/IPv4 sockets).
659: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
660: - DISP now locks stdout;
661: - rpliconv is added to replace standard iconv provided by operating system.
662: Indeed, conversion between different encodages requires transliteration
663: that is not offered by some iconv utility;
664: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
665: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

667: - fprintf is replaced by some functions that allow transliterations between
668: locales;
669: - '"' can now be used in strings ("\"");
670: - iconv is called with -c in preprocessor stage. It is done to write
671: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
672: - double free is fixed in liberation() (type SQL, only occurs when locale is
673: set);
674: - LOCALIZATION, UCASE and LCASE are added;

678: used in onLoading from shared library, USE was pushed on stack as algebraic
679: expression;
680: - libiconv is upgraded to 1.13.1;
681: - gnuplot is upgraded to 4.2.6;
682: - gsl is upgraded to 1.13.

684: - pipe() is overwritten by a macro to avoid a system error. Communication
685: between process are done with pipes and these pipes are managed by a
686: specific asynchrone thread. If a script try to create more threads than
687: management thread can destroy, you can quickly achieve maximum number of
688: opened files and pipe() shall return a system error. This macro tries to create
689: pipes. If pipe() function returns an error, macro waits and retries. If
690: number of retries is greater than a hardcoded value, macro returns an error;
691: - major bug (deadlock) is fixed in process and thread management. I hope
692: this bug shall be the last one;
693: - major bug is fixed in DET intrinsic (determinant was computed without LU

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

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

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

1169: not writable;
1170: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1171: error scrutation.

1216: - variable management routines have been rewritten. The new ones are
1217: uncompatible with the old ones. Before these changes, a local variable
1218: was exported to a child subroutine, but cannot be modified into this
1219: child subroutine. Now, a local variable is accessible only in its subroutine;
1220: - SAVE intrinsic is added to manipulate global variables;

1538: (less parenthesis);
1539: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1540: on Debian distribution, but since cpp is in the default path, RPL/2 works
1541: fine...);
1542: - NOT is not correctly formatted in formateur.c:
1543: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1544: with a NOTZ function !
1545: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1546: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1547: if the main loop is in a program;
1548: - RPL/2 is tested with efence and valgrind;
1549: - configure.in script is modified;
1550: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1551: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1552: another gcc bug...
1553: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)
1554: - EXIT is fixed. Now, it is possible to use EXIT in an expression when the
1555: main loop is in a program;

1586: 2: integer (number of column to be inserted)
1587: 1: column matrix to be inserted;
1588: - major bug was discovered in interface_gnuplot(). It only occurs when

1597: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1598: - SLICESCALE intrinsic is added. Its syntax is
1599: { "automatic" nb_of_levels }
1600: { "discrete" l1 l2 l3 ... }
1601: { "incremental" start incr }
1602: { "incremental" start incr end }
1603: { "automatic" } (default);

1611: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1612: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1613: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1630: - SCLS is added;
1631: - DRWS now uses COLS to draw 2D graphics;
1632: - PPAR and SPAR are written. SPAR returns a list that contains the
1633: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1634: statistical variable, or "DISABLED" if its type is not one of the type of
1635: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1636: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1637: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1638: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1639: disabled. Arguments of EXTERNAL are case sensitive because the external
1640: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1641: of known external functions but add the new list to the last. { "all" }
1642: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1643: external names of the known functions;
1644: - mkrplso.in is modified.
1645: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1646: - vim syntax file is upgraded;
1647: - a minor mistake is fixed in recherche_instruction_suivante();
1648: - some minor memory leaks are fixed in recherche_type() function. They only

1656: - PUTC and PUTR new intrinsics are added.
1657: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1658: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1659: VISIT does not find a name in level 1;
1660: - configure.in script is modified to add a new test (--enable-debug
1661: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1662: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1663: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1664: 'MATRIX' { 2 2 3 } GETR;
1665: - LOGSCALE intrinsic is improved and now, it can be used as
1666: { "main" "auxiliary" X Y } LOGSCALE;
1667: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1668: same than AXES:
1669: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1670: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1671: { { -10 10 } "automatic" } SCALE.
1672: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1673: because it changes only the dimension of the screen. To have a logarithmic
1674: scale, you must use LOGSCALE intrinsic:
1675: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1676: screen on second scale;
1677: - { X X } autoscale and { Y Y } logscale are now invalid;
1678: - *D is added (depth multiplication, for 3D graphics);
1679: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1680: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1681: - a major bug is fixed in GETI instrinsic when it is used with a name
1682: that contains a matrix or a vector (bad upper bounds conditions in
1683: incrementation);
1684: - DISP intrinsic now uses the 33-th flag. When it is not set
1685: (default), a final carriage return is sent to the terminal;
1686: - AXES intrinsic only takes a list that can contains the keywork
1687: "main" or "auxiliary". Before this modification, this keyword was in
1688: the first stack level;
1689: - vim syntax file is upgraded;
1690: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1691: option;
1692: - LAST is now disabled in the main loop of INT intrinsic;
1693: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1694: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1695: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1696: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1697: in 0);
1698: - LAST is disabled in the main loop of DRAW intrinsic;
1699: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1700: evaluation of an equation, the system stack is returned corrupted to the
1701: sequencer;
1702: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1703: of a loop are not integer or real.
1704: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1705: - the compilation stage aborts with an error message when two definitions
1706: have the same name. To improve the compilation() subroutine, I have to
1707: add some tests in gestion_variables.c;
1708: - recherche_type() subroutine ad some other connex subroutines are improved.
1709: Now, some syntax errors about object are caught and do not perform sequencer
1710: hangup;

1712: - Makefile.am's and configure.in scripts are improved.
1713: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1714: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1715: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1716: the boxwidth, 1 by default);
1717: - recherche_type() is rewritten to be faster;
1718: - gsl is upgraded (release 1.3);
1719: - ncurses is upgraded and patched (release 5.3);
1720: - recherche_instruction_suivante() is fixed (string research with included
1721: '"') and rewritten to be faster;

1732: - a minor bug is fixed in evaluation subroutine;
1733: - vim syntax file is improved;
1734: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1735: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1736: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1737: is a quick and dirty workaround...);
1738: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1739: - rplconvert is improved.
1740: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1756: Now, an expression such as 'A+' returns an error when it is analyzed;
1757: - VISIT intrinsic is added;
1758: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1759: normal mode.
