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

819: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
820: - FORTRAN 77 file management subroutines are rewritten in pure C due to
821: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
822: in some cases (gcc/gfortran/libc/OS and arch conjonction);
823: - a memory leak is fixed in REMOVE intrinsic;
824: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()

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

864: deadlock when a huge amount of threads is launched);
865: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
866: arguments types are unsupported;

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

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

998: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
999: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
1000: workaround for this major bug. Nevertheless, all others capabilities seems to
1001: work fine;

1047: - major bug fixed in formateur() (segfault when a symbol is used without "'");
1048: - major bug is fixed in DUPN intrinsic;
1049: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
1050: before starting interrupt evaluation;
1051: - -f parameter is added when iconv is called;
1052: - as old file program was bugged, a new option is added to configure script.
1053: When configure is called with --disable-encoding-autodetection, make does not

1060: - -p option is added. With this option, all scripts are compiled before
1061: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
1062: 40% faster;
1063: - read and write operations in pipe() are rewritten to be sure that such
1064: operations are atomic;

1260: - PROTECT and UNPROTECT are added to protect variables against write
1261: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1262: versions of PROTECT and UNPROTECT that only deal with global variables
1263: (see RCL/SAVE);
1264: - variable management routines have been rewritten. The new ones are
1265: uncompatible with the old ones. Before these changes, a local variable
1266: was exported to a child subroutine, but cannot be modified into this
1267: child subroutine. Now, a local variable is accessible only in its subroutine;
1268: - SAVE intrinsic is added to manipulate global variables;

1589: fine...);
1590: - NOT is not correctly formatted in formateur.c:
1591: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1592: with a NOTZ function !
1593: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1596: - RPL/2 is tested with efence and valgrind;
1597: - configure.in script is modified;
1598: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1659: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1660: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1661: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1678: - SCLS is added;
1679: - DRWS now uses COLS to draw 2D graphics;
1680: - PPAR and SPAR are written. SPAR returns a list that contains the
1681: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1682: statistical variable, or "DISABLED" if its type is not one of the type of
1683: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1684: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1685: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1686: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1687: disabled. Arguments of EXTERNAL are case sensitive because the external
1688: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1689: of known external functions but add the new list to the last. { "all" }
1690: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1691: external names of the known functions;
1692: - mkrplso.in is modified.
1693: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1694: - vim syntax file is upgraded;
1695: - a minor mistake is fixed in recherche_instruction_suivante();

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