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

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

916: SQLQUERY. With all new programs, you can open a real connection to databases;
917: - NRPROC is added. This new intrinsic is used to catch error from child
918: process. Without NRPROC, any errors returned by child process cause
919: main process to abort;
920: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
921: starts a new process). There are no mutexes in RPL/2 because all spawned process
922: use specific context. Nevertheless, shared variables and associated mutexes

1055: { "mysql:iso-8859-1" "server" "database" ... };
1056: - major bug is fixed un analyse_algebrique(). When DISP printed an algebraic
1057: object, 'DISP()' was pushed in stack;
1058: - same major bug is fixed in <, >, <=, >= and <>;
1059: - major bug fixed in formateur() (segfault when a symbol is used without "'");

1061: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
1062: before starting interrupt evaluation;
1063: - -f parameter is added when iconv is called;
1064: - as old file program was bugged, a new option is added to configure script.
1065: When configure is called with --disable-encoding-autodetection, make does not
1066: try to detect source encoding. Please, do not use if RPL/2 can be built
1067: without this option !
1068: - new garbage collector (and more efficient) is written;
1069: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1070: not support real time signals, RPL/2 cannot use multitasking functions;
1071: - error returned by preprocessor are now catched by RPL/2;
1072: - -p option is added. With this option, all scripts are compiled before
1073: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
1074: 40% faster;
1075: - read and write operations in pipe() are rewritten to be sure that such
1076: operations are atomic;
1077: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1104: greater than one second. On some systems, usleep argument must be lower
1105: than 1E6;
1106: - numeric and character formats are now tested;
1107: - -A flag is added. -A is used to give command line parameters to main
1108: routine. Example:
1109: rayleigh:[~/rpl-4.0.0.prerelease.2/examples] > ./test3.rpl -A "<< X sin >>"

1155: - major bug is fixed in tex.h (multiline strings);
1156: - examples subdir is added;
1157: - major bug is fixed in recherche_variable(). When an expression is evaluated
1158: in a function, all variables set in this function must be visible in

1217: - HELP function is rewritten to be more friendly (a la OpenVMS);
1218: - external wrapper (rplplot) is written to force usage of gnuplot provided
1219: by RPL/2 if it is built during build process. If this build does not exist,
1220: it tries to launch regular gnuplot;
1221: - gnuplot is added to source tree to avoid some trouble between preinstalled
1222: gnuplot and release used by RPL/2. This addition to source tree is
1223: required by some incompatibility between gnuplot releases;

1229: not writable;
1230: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1231: error scrutation.

1271: With STATIC, next variables created by '->' are static;
1272: - PROTECT and UNPROTECT are added to protect variables against write
1273: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1274: versions of PROTECT and UNPROTECT that only deal with global variables
1275: (see RCL/SAVE);
1276: - variable management routines have been rewritten. The new ones are
1277: uncompatible with the old ones. Before these changes, a local variable
1278: was exported to a child subroutine, but cannot be modified into this
1279: child subroutine. Now, a local variable is accessible only in its subroutine;
1280: - SAVE intrinsic is added to manipulate global variables;

1317: multithreading. DETACH, SEND and RECV now use four real time signals to
1318: perform a better task synchronization;
1319: - some bugs introduced by locales specific compilations are fixed;
1320: - major memory corruption is fixed in DEPND;
1321: - HELP intrinsic is modified to print a classified output.

1332: - major bug is fixed in evaluation() subroutine. Value of error flag
1333: was not returned in some cases;
1334: - FACT intrinsic does not accept real arguments anymore due to the new intrinsic
1335: GAMMA;
1336: - GAMMA intrinsic is added (complex function) ;
1337: - autoconf/automake scripts are modified to compile F90 sources;

1601: fine...);
1602: - NOT is not correctly formatted in formateur.c:
1603: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1604: with a NOTZ function !
1605: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1608: - RPL/2 is tested with efence and valgrind;
1609: - configure.in script is modified;
1610: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1671: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1672: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1673: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1691: - DRWS now uses COLS to draw 2D graphics;
1692: - PPAR and SPAR are written. SPAR returns a list that contains the
1693: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1694: statistical variable, or "DISABLED" if its type is not one of the type of
1695: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1696: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1697: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1698: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1699: disabled. Arguments of EXTERNAL are case sensitive because the external
1700: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1701: of known external functions but add the new list to the last. { "all" }
1702: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1703: external names of the known functions;
1704: - mkrplso.in is modified.
1705: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1706: - vim syntax file is upgraded;
1707: - a minor mistake is fixed in recherche_instruction_suivante();

1718: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1719: VISIT does not find a name in level 1;
1720: - configure.in script is modified to add a new test (--enable-debug
1721: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1722: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1723: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1724: 'MATRIX' { 2 2 3 } GETR;
1725: - LOGSCALE intrinsic is improved and now, it can be used as
1726: { "main" "auxiliary" X Y } LOGSCALE;
1727: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1728: same than AXES:
1729: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1730: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1731: { { -10 10 } "automatic" } SCALE.
1732: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1733: because it changes only the dimension of the screen. To have a logarithmic
1734: scale, you must use LOGSCALE intrinsic:
1735: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1736: screen on second scale;
1737: - { X X } autoscale and { Y Y } logscale are now invalid;
1738: - *D is added (depth multiplication, for 3D graphics);
1739: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1740: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1741: - a major bug is fixed in GETI instrinsic when it is used with a name
1742: that contains a matrix or a vector (bad upper bounds conditions in
1743: incrementation);
1744: - DISP intrinsic now uses the 33-th flag. When it is not set
1745: (default), a final carriage return is sent to the terminal;
1746: - AXES intrinsic only takes a list that can contains the keywork
1747: "main" or "auxiliary". Before this modification, this keyword was in
1748: the first stack level;
1749: - vim syntax file is upgraded;
1750: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1751: option;
1752: - LAST is now disabled in the main loop of INT intrinsic;
1753: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1754: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1755: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1756: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1757: in 0);
1758: - LAST is disabled in the main loop of DRAW intrinsic;
1759: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1760: evaluation of an equation, the system stack is returned corrupted to the
1761: sequencer;
1762: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1763: of a loop are not integer or real.
1764: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1765: - the compilation stage aborts with an error message when two definitions
1766: have the same name. To improve the compilation() subroutine, I have to
1767: add some tests in gestion_variables.c;
1768: - recherche_type() subroutine ad some other connex subroutines are improved.
1769: Now, some syntax errors about object are caught and do not perform sequencer
1770: hangup;
