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

426: - fix major memory access violation in evaluation subroutine. Only occurs
427: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;

668: Number of scalar operations per second and per core : 2383016
669:
670: - PULPRFL does not abort on BUG() but on execution error;
671: - TRIM, REPL and TOKENIZE are added;
672: - sockets options are now set before bind();
673: - shutdown() is added to all connected sockets;
674: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
675: list argument and inexistant elements).
676: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
677: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
678: signals sent to main process were not caught because DAEMON did not replace
679: old pid by new one;
680: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
681: evaluation when an error is reported from a subroutine in another subroutine.
682: For example, error was not caught in following program when it is executed with
683: -p option :
684: TEST << iferr TEST2 then end >>
685: TEST2 << 0 inv >>
686: - major bug is fixed in variable management. Some local variables were
687: seen as global ones;
688: - major bug is fixed in rplcore. Rplcore entered in dead lock when
689: script file contains a multibyte character;
690: - IN intrinsic is added;
691: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
692: returned false ;
693: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
694: programs;
695: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
696: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
697: strings were never closed;
698: - some bugs have been fixed in file management;
699: - RPL/2 can now be run on EBCDIC systems (OS/390);
700: - major bug is fixed in -A command line option (NULL character is missing);
701: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
702: made by blocks (1024 bytes). When an incomplete multibyte sequence is
703: encountered at end of block, subroutine aborts with an execution error;
704: - major bug is fixed in OPEN (TCP/IPv4 sockets).
705: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
706: - DISP now locks stdout;
707: - rpliconv is added to replace standard iconv provided by operating system.
708: Indeed, conversion between different encodages requires transliteration
709: that is not offered by some iconv utility;
710: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
711: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
712: not be found), SYSEVAL enters in a dead lock;
713: - fprintf is replaced by some functions that allow transliterations between
714: locales;
715: - '"' can now be used in strings ("\"");
716: - iconv is called with -c in preprocessor stage. It is done to write
717: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
718: - double free is fixed in liberation() (type SQL, only occurs when locale is
719: set);
720: - LOCALIZATION, UCASE and LCASE are added;
721: - major bug is fixed in EXIT intrinsic that was able to return a false
722: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
723: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
724: used in onLoading from shared library, USE was pushed on stack as algebraic
725: expression;
726: - libiconv is upgraded to 1.13.1;
727: - gnuplot is upgraded to 4.2.6;
728: - gsl is upgraded to 1.13.
729: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
730: - pipe() is overwritten by a macro to avoid a system error. Communication
731: between process are done with pipes and these pipes are managed by a
732: specific asynchrone thread. If a script try to create more threads than
733: management thread can destroy, you can quickly achieve maximum number of
734: opened files and pipe() shall return a system error. This macro tries to create
735: pipes. If pipe() function returns an error, macro waits and retries. If
736: number of retries is greater than a hardcoded value, macro returns an error;
737: - major bug (deadlock) is fixed in process and thread management. I hope
738: this bug shall be the last one;
739: - major bug is fixed in DET intrinsic (determinant was computed without LU
740: diagonalization);
741: - SWAPCNTXT is added;
742: - minor bug is fixed in Makefile.am (licences rule).
743: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
744: - some bugfixes are added in process management;
745: - all process management is rewritten to avoid usage of defunct process
746: or thread number;
747: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
748: was called before a pending interruption5 (SIGFSTOP), signal handler uses
749: a freed semaphore and corrupts heap;
750: - CLRERR is added to erase previous errors;
751: - ERRN and ERRM return exception message and number;
752: - major bug is fixed in interruptions.c. All signal are now bufferised
753: when semaphore_liste_threads is null to avoid deadlock. This bug only
754: occured when STOP was sent to a dying thread or process (when this thread or
755: process was running retrait_thread());
756: - matrix rank is computed before matrix inversion;
757: - file locks are added to stdin and stdout. stderr is not locked because
758: all messages written by signal handlers are sent to stderr;
759: - configure.in script is modified to test gcc version and avoid a bug in
760: gcc older than 4.4;
761: - some benchmarks have been done :

790: -Wno-unused-parameter;
791: - all mathematical exceptions are now signaled by exceptions instead of
792: execution error;
793: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
794: can call twice CSTOP without RSTOP;
795: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
796: SMPHRTRYDECR, SMPHGETV).
797: * Fri Jul 24 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.4 (RPL/2)
798: - semaphore is added in interruptions.c to avoid segmentation fault when STOP
799: signal is sent to a dying thread. Some mutexes are replaced by semaphores too
800: to be used in signal handlers;
801: - major bug (memory corruption) is fixed in COL- intrinsic;
802: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
803: software interrupt was caught;
804: - rplpp man page is added.
805: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)

817: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
818: - FORTRAN 77 file management subroutines are rewritten in pure C due to
819: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
820: in some cases (gcc/gfortran/libc/OS and arch conjonction);
821: - a memory leak is fixed in REMOVE intrinsic;
822: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
823: and due to a libmysqlclient that is not thread safe).
824: * Wen Jun 10 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.2 (RPL/2)
825: - new enhanced allocator is written for regular variables, static variables and

828: when SQL support was not enabled;
829: - new allocator is written for system stack and last stack;
830: - --enable-profile flag is added to configure script. When this flag is
831: enabled, rpl is built with -pg option;
832: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
833: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
834: process is killed;
835: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
836: know typeof() intrinsic function. This function is not standard but exists
837: under Sun Studio, gcc, and maybe some others compilers. If this function does
838: not exist on your compiler, you can change its definition by old one in
839: src/rpl.h;
840: - fflush() can now be interrupted by signal (SunOS);
841: - fflush(NULL) is called before all fork() occurrences;

860: is send from an external process;
861: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
862: deadlock when a huge amount of threads is launched);
863: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
864: arguments types are unsupported;
865: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
866: data are buffered. PLOT is used to draw these objects.);
867: - MARK instrinsic is added;
868: - new allocator mechanism is written;
869: - some regression bugs have been fixed, some memory leaks too.
870: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)

880: static variable that is shared by multiple threads;
881: - '->' intrinsic is improved. All object copies have been avoided;
882: - -n flag is added to catch HUP signal. stderr and stdout are redirected
883: to a file, stdin is redirected to /dev/null when control process is killed;
884: - a mutex is added to each object (before this modification,
885: RPL/2 used a global mutex and performances in multithreaded programs were very
886: poor.);
887: - ALARM is now interruptible;
888: - both PUT and PUTI intrinsics are improved and do not copy list and table
889: when nombre_occurrences == 1;

900: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
901: that all programs that worked with old SQL intrinsic can now work with
902: SQLQUERY. With all new programs, you can open a real connection to databases;
903: - NRPROC is added. This new intrinsic is used to catch error from child
904: process. Without NRPROC, any errors returned by child process cause
905: main process to abort;
906: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
907: starts a new process). There are no mutexes in RPL/2 because all spawned process
908: use specific context. Nevertheless, shared variables and associated mutexes
909: should be added;
910: - -D flag and DAEMONIZE intrinsic have been added;

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

980: nullified lists;
981: - rplexternals.h is modified and improved;
982: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and
983: configure script.
984: * Mon Jun 23 2008 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.7 (RPL/2)

995: - FUSE, RFUSE and CLRFUSE have been added;
996: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
997: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
998: workaround for this major bug. Nevertheless, all others capabilities seems to
999: work fine;
1000: - '->' is modified to return error when program tries to initialiaze two
1001: variables with the same name like

1014: - SIGPIPE signal handler is modified to avoid abort process when POKE tries
1015: to write data into a pipe without reader;
1016: - major bug is fixed in RETURN intrinsic. When RETURN was called from a detached

1025: Main usages of these intrinsics are in conjonction with IFERR or with
1026: software interrupts;
1027: - HEAD, TAIL and REVLIST intrinsics are added;

1032: time signals have been removed;
1033: - major bugs are fixed in multitasking (mutex trouble _and_ segmentation fault);
1034: - minor bug is fixed in STR->. STR-> could return a system error instead an
1035: execution one;
1036: - first bug due to new garbage collector is fixed in '+' ({ } { } +) and in
1037: '-' intrinsics;
1038: - PostgreSQL support is written.

1041: { "mysql:iso-8859-1" "server" "database" ... };
1042: - major bug is fixed un analyse_algebrique(). When DISP printed an algebraic
1043: object, 'DISP()' was pushed in stack;
1044: - same major bug is fixed in <, >, <=, >= and <>;
1045: - major bug fixed in formateur() (segfault when a symbol is used without "'");
1046: - major bug is fixed in DUPN intrinsic;
1047: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
1048: before starting interrupt evaluation;
1049: - -f parameter is added when iconv is called;
1050: - as old file program was bugged, a new option is added to configure script.
1051: When configure is called with --disable-encoding-autodetection, make does not
1052: try to detect source encoding. Please, do not use if RPL/2 can be built
1053: without this option !
1054: - new garbage collector (and more efficient) is written;
1055: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1056: not support real time signals, RPL/2 cannot use multitasking functions;

1262: - variable management routines have been rewritten. The new ones are
1263: uncompatible with the old ones. Before these changes, a local variable
1264: was exported to a child subroutine, but cannot be modified into this
1265: child subroutine. Now, a local variable is accessible only in its subroutine;
1266: - SAVE intrinsic is added to manipulate global variables;

1587: fine...);
1588: - NOT is not correctly formatted in formateur.c:
1589: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1590: with a NOTZ function !
1591: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1594: - RPL/2 is tested with efence and valgrind;
1595: - configure.in script is modified;
1596: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1597: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1657: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1658: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1659: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1676: - SCLS is added;
1677: - DRWS now uses COLS to draw 2D graphics;
1678: - PPAR and SPAR are written. SPAR returns a list that contains the
1679: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1680: statistical variable, or "DISABLED" if its type is not one of the type of
1681: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1682: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1683: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1684: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1685: disabled. Arguments of EXTERNAL are case sensitive because the external
1686: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1687: of known external functions but add the new list to the last. { "all" }
1688: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1689: external names of the known functions;
1690: - mkrplso.in is modified.
1691: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1692: - vim syntax file is upgraded;
1693: - a minor mistake is fixed in recherche_instruction_suivante();

1704: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1705: VISIT does not find a name in level 1;
1706: - configure.in script is modified to add a new test (--enable-debug
1707: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1708: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1709: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1710: 'MATRIX' { 2 2 3 } GETR;
1711: - LOGSCALE intrinsic is improved and now, it can be used as
1712: { "main" "auxiliary" X Y } LOGSCALE;
1713: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1714: same than AXES:
1715: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1716: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1717: { { -10 10 } "automatic" } SCALE.
1718: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1719: because it changes only the dimension of the screen. To have a logarithmic
1720: scale, you must use LOGSCALE intrinsic:
1721: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1722: screen on second scale;
1723: - { X X } autoscale and { Y Y } logscale are now invalid;
1724: - *D is added (depth multiplication, for 3D graphics);
1725: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1726: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1727: - a major bug is fixed in GETI instrinsic when it is used with a name
1728: that contains a matrix or a vector (bad upper bounds conditions in
1729: incrementation);
1730: - DISP intrinsic now uses the 33-th flag. When it is not set
1731: (default), a final carriage return is sent to the terminal;
1732: - AXES intrinsic only takes a list that can contains the keywork
1733: "main" or "auxiliary". Before this modification, this keyword was in
1734: the first stack level;
1735: - vim syntax file is upgraded;
1736: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1737: option;
1738: - LAST is now disabled in the main loop of INT intrinsic;
1739: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1740: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1741: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1742: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1743: in 0);
1744: - LAST is disabled in the main loop of DRAW intrinsic;
1745: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1746: evaluation of an equation, the system stack is returned corrupted to the
1747: sequencer;
1748: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1749: of a loop are not integer or real.
1750: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1751: - the compilation stage aborts with an error message when two definitions
1752: have the same name. To improve the compilation() subroutine, I have to
1753: add some tests in gestion_variables.c;
1754: - recherche_type() subroutine ad some other connex subroutines are improved.
1755: Now, some syntax errors about object are caught and do not perform sequencer
1756: hangup;
1757: - readline is upgraded (minor compilation bug with recent gcc);
1758: - Makefile.am's and configure.in scripts are improved.
1759: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1760: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1761: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1762: the boxwidth, 1 by default);
1763: - recherche_type() is rewritten to be faster;
1764: - gsl is upgraded (release 1.3);
1765: - ncurses is upgraded and patched (release 5.3);
1766: - recherche_instruction_suivante() is fixed (string research with included
1767: '"') and rewritten to be faster;
1768: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1769: segfault.
1770: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)
1771: - RPL/2 is compiled by gcc-3.2.2 and seems to work;
1772: - the same minor bug is fixed in REDRAW and DRAX functions;
1773: - a minor fix is written in DRAW function (2D and 3D);
