398: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
399: "ALL" IMPLICIT when it runs in interactive mode;
400: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used

402: to use SAVE to manipulate global variables;
403: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
404: subroutines;
405: - fix major memory access violation in evaluation subroutine. Only occurs
406: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;

442: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 443: - gnuplot is upgraded to 4.4.1;
444: - deadlock is fixed in signal handlers: same mutex was used in standard

466: systems that does not provide correct POSIX or SysV semaphores subsystem;
467: - a dirty but not quick patch is written to workaround broken siginfo
468: structures. This patch has been successfully tested. It uses a segment of

670: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
671: returned false ;
672: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
673: programs;
674: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
675: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
676: strings were never closed;
677: - some bugs have been fixed in file management;
678: - RPL/2 can now be run on EBCDIC systems (OS/390);
679: - major bug is fixed in -A command line option (NULL character is missing);
680: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
681: made by blocks (1024 bytes). When an incomplete multibyte sequence is
682: encountered at end of block, subroutine aborts with an execution error;
683: - major bug is fixed in OPEN (TCP/IPv4 sockets).
684: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
685: - DISP now locks stdout;
686: - rpliconv is added to replace standard iconv provided by operating system.
687: Indeed, conversion between different encodages requires transliteration
688: that is not offered by some iconv utility;
689: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
690: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
691: not be found), SYSEVAL enters in a dead lock;
692: - fprintf is replaced by some functions that allow transliterations between
693: locales;
694: - '"' can now be used in strings ("\"");
695: - iconv is called with -c in preprocessor stage. It is done to write
696: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
697: - double free is fixed in liberation() (type SQL, only occurs when locale is
698: set);
699: - LOCALIZATION, UCASE and LCASE are added;
700: - major bug is fixed in EXIT intrinsic that was able to return a false
701: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
702: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
703: used in onLoading from shared library, USE was pushed on stack as algebraic
704: expression;
705: - libiconv is upgraded to 1.13.1;
706: - gnuplot is upgraded to 4.2.6;
707: - gsl is upgraded to 1.13.
708: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
709: - pipe() is overwritten by a macro to avoid a system error. Communication
710: between process are done with pipes and these pipes are managed by a
711: specific asynchrone thread. If a script try to create more threads than
712: management thread can destroy, you can quickly achieve maximum number of
713: opened files and pipe() shall return a system error. This macro tries to create
714: pipes. If pipe() function returns an error, macro waits and retries. If
715: number of retries is greater than a hardcoded value, macro returns an error;
716: - major bug (deadlock) is fixed in process and thread management. I hope
717: this bug shall be the last one;
718: - major bug is fixed in DET intrinsic (determinant was computed without LU
719: diagonalization);
720: - SWAPCNTXT is added;
721: - minor bug is fixed in Makefile.am (licences rule).
722: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
723: - some bugfixes are added in process management;
724: - all process management is rewritten to avoid usage of defunct process
725: or thread number;
726: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
727: was called before a pending interruption5 (SIGFSTOP), signal handler uses
728: a freed semaphore and corrupts heap;
729: - CLRERR is added to erase previous errors;
730: - ERRN and ERRM return exception message and number;
731: - major bug is fixed in interruptions.c. All signal are now bufferised
732: when semaphore_liste_threads is null to avoid deadlock. This bug only
733: occured when STOP was sent to a dying thread or process (when this thread or
734: process was running retrait_thread());
735: - matrix rank is computed before matrix inversion;
736: - file locks are added to stdin and stdout. stderr is not locked because
737: all messages written by signal handlers are sent to stderr;
738: - configure.in script is modified to test gcc version and avoid a bug in
739: gcc older than 4.4;
740: - some benchmarks have been done :

779: to be used in signal handlers;
780: - major bug (memory corruption) is fixed in COL- intrinsic;
781: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
782: software interrupt was caught;

809: - --enable-profile flag is added to configure script. When this flag is
810: enabled, rpl is built with -pg option;
811: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
812: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
813: process is killed;
814: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
815: know typeof() intrinsic function. This function is not standard but exists
816: under Sun Studio, gcc, and maybe some others compilers. If this function does
817: not exist on your compiler, you can change its definition by old one in
818: src/rpl.h;
819: - fflush() can now be interrupted by signal (SunOS);
820: - fflush(NULL) is called before all fork() occurrences;

841: deadlock when a huge amount of threads is launched);
842: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
843: arguments types are unsupported;
844: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
845: data are buffered. PLOT is used to draw these objects.);
846: - MARK instrinsic is added;
847: - new allocator mechanism is written;
848: - some regression bugs have been fixed, some memory leaks too.
849: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)

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

879: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
880: that all programs that worked with old SQL intrinsic can now work with
881: SQLQUERY. With all new programs, you can open a real connection to databases;
882: - NRPROC is added. This new intrinsic is used to catch error from child
883: process. Without NRPROC, any errors returned by child process cause
884: main process to abort;
885: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
886: starts a new process). There are no mutexes in RPL/2 because all spawned process
887: use specific context. Nevertheless, shared variables and associated mutexes
888: should be added;
889: - -D flag and DAEMONIZE intrinsic have been added;

939: - ->TABLE and TABLE-> intrinsics are added;
940: - major bug is fixed in recherche_type(). Only occurs when rpl executes
941: precompiled scripts;

959: nullified lists;
960: - rplexternals.h is modified and improved;
961: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and

975: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
976: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
977: workaround for this major bug. Nevertheless, all others capabilities seems to
978: work fine;

1027: before starting interrupt evaluation;
1028: - -f parameter is added when iconv is called;
1029: - as old file program was bugged, a new option is added to configure script.
1030: When configure is called with --disable-encoding-autodetection, make does not
1031: try to detect source encoding. Please, do not use if RPL/2 can be built
1032: without this option !
1033: - new garbage collector (and more efficient) is written;
1034: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1035: not support real time signals, RPL/2 cannot use multitasking functions;
1036: - error returned by preprocessor are now catched by RPL/2;
1037: - -p option is added. With this option, all scripts are compiled before
1038: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run

1182: - HELP function is rewritten to be more friendly (a la OpenVMS);
1183: - external wrapper (rplplot) is written to force usage of gnuplot provided
1184: by RPL/2 if it is built during build process. If this build does not exist,
1185: it tries to launch regular gnuplot;
1186: - gnuplot is added to source tree to avoid some trouble between preinstalled
1187: gnuplot and release used by RPL/2. This addition to source tree is

1237: - PROTECT and UNPROTECT are added to protect variables against write
1238: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1239: versions of PROTECT and UNPROTECT that only deal with global variables
1240: (see RCL/SAVE);
1241: - variable management routines have been rewritten. The new ones are
1242: uncompatible with the old ones. Before these changes, a local variable
1243: was exported to a child subroutine, but cannot be modified into this
1244: child subroutine. Now, a local variable is accessible only in its subroutine;
1245: - SAVE intrinsic is added to manipulate global variables;

1566: fine...);
1567: - NOT is not correctly formatted in formateur.c:
1568: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1569: with a NOTZ function !
1570: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1573: - RPL/2 is tested with efence and valgrind;
1574: - configure.in script is modified;
1575: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1636: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1637: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1638: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1655: - SCLS is added;
1656: - DRWS now uses COLS to draw 2D graphics;
1657: - PPAR and SPAR are written. SPAR returns a list that contains the

1659: statistical variable, or "DISABLED" if its type is not one of the type of
1660: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1661: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1662: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1663: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1664: disabled. Arguments of EXTERNAL are case sensitive because the external
1665: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1666: of known external functions but add the new list to the last. { "all" }
1667: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1668: external names of the known functions;
1669: - mkrplso.in is modified.
1670: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1671: - vim syntax file is upgraded;
1672: - a minor mistake is fixed in recherche_instruction_suivante();

1683: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1684: VISIT does not find a name in level 1;
1685: - configure.in script is modified to add a new test (--enable-debug
1686: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1687: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1688: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1689: 'MATRIX' { 2 2 3 } GETR;
1690: - LOGSCALE intrinsic is improved and now, it can be used as
1691: { "main" "auxiliary" X Y } LOGSCALE;
1692: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1693: same than AXES:
1694: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1695: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1696: { { -10 10 } "automatic" } SCALE.
1697: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1698: because it changes only the dimension of the screen. To have a logarithmic
1699: scale, you must use LOGSCALE intrinsic:
1700: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1701: screen on second scale;
1702: - { X X } autoscale and { Y Y } logscale are now invalid;
1703: - *D is added (depth multiplication, for 3D graphics);
1704: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1705: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1706: - a major bug is fixed in GETI instrinsic when it is used with a name
1707: that contains a matrix or a vector (bad upper bounds conditions in
1708: incrementation);
1709: - DISP intrinsic now uses the 33-th flag. When it is not set
1710: (default), a final carriage return is sent to the terminal;
1711: - AXES intrinsic only takes a list that can contains the keywork
1712: "main" or "auxiliary". Before this modification, this keyword was in
1713: the first stack level;
1714: - vim syntax file is upgraded;
1715: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1716: option;
1717: - LAST is now disabled in the main loop of INT intrinsic;
1718: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1719: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1720: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1721: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1722: in 0);
1723: - LAST is disabled in the main loop of DRAW intrinsic;
1724: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1725: evaluation of an equation, the system stack is returned corrupted to the
1726: sequencer;
1727: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1728: of a loop are not integer or real.
1729: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1730: - the compilation stage aborts with an error message when two definitions
1731: have the same name. To improve the compilation() subroutine, I have to
1732: add some tests in gestion_variables.c;
1733: - recherche_type() subroutine ad some other connex subroutines are improved.
1734: Now, some syntax errors about object are caught and do not perform sequencer
1735: hangup;
1736: - readline is upgraded (minor compilation bug with recent gcc);
1737: - Makefile.am's and configure.in scripts are improved.
1738: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1739: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1740: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1741: the boxwidth, 1 by default);
1742: - recherche_type() is rewritten to be faster;
1743: - gsl is upgraded (release 1.3);
1744: - ncurses is upgraded and patched (release 5.3);
1745: - recherche_instruction_suivante() is fixed (string research with included
1746: '"') and rewritten to be faster;

1757: - a minor bug is fixed in evaluation subroutine;
1758: - vim syntax file is improved;
1759: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1760: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1761: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1762: is a quick and dirty workaround...);
1763: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1764: - rplconvert is improved.
1765: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
