413: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
414: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
415: "ALL" IMPLICIT when it runs in interactive mode;
416: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
417: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
418: to use SAVE to manipulate global variables;
419: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
420: subroutines;
421: - fix major memory access violation in evaluation subroutine. Only occurs
422: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
423: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
424: when X was a vector or a table.

1.52 bertrand 454: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
455: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
456: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
457: corruption. As internal memory management have been improved, a best fit
458: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 459: - gnuplot is upgraded to 4.4.1;
460: - deadlock is fixed in signal handlers: same mutex was used in standard
461: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
462: and signal handlers. A new signal handler specific mutex is added;
463: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
464: that has to be evaluated by ->NUM;
1.49 bertrand 465: - rplfile build process is modify to be sure that rplfile is not modified
466: after rpl build stage (to be sure that rplfile checksum is not modified after
467: rpl compilation);
1.51 bertrand 468: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
469: modified to remove yacc code and renamed;

471: ABORT now works on eComStation;
472: - sqlite is upgraded to 3.7.2;
473: - bug is fixed in software interrupts. When both process have different PID,
474: parent process was not interrupted if it is not group master process. To fix
475: this bug, SIGINJECT signal is not sent by child process but by control thread
476: in parent process;
1.46 bertrand 477: - minor bug is fixed in data injection (POKE) that does not work as expected
478: when child process is protected by NRPROC.

1.43 bertrand 480: - --enable-sysv-sems is added to configure script to use SystemV semaphores
481: functions instead of POSIX functions. This function is disabled or forced on
482: systems that does not provide correct POSIX or SysV semaphores subsystem;
483: - a dirty but not quick patch is written to workaround broken siginfo
484: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 485: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 486: (Unix PID);
1.41 bertrand 487: - some OpenBSD's hacks are added;
488: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 489: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

1.37 bertrand 503: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 504: - units is upgraded to 1.88;
505: - another major bug is fixed in the same variable creation subroutine.
506: Level 0 and 1 variables adresses were swapped when a global variable masked
507: a name of RPL/2 routine;
1.35 bertrand 508: - major bug is fixed in global variable creation subroutine. When a global
509: variable was created and when a local variable existed with the same name,
510: computed address of global variable was wrong;
511: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
512: is forced in front of all libraries.
1.34 bertrand 513: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
514: - BACKTRACE intrinsic is added;
515: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
516: when this structure is included in IFERR/THEN/END structure and when an error is
517: caught;
518: - major bug is fixed in analyse() subroutine. When evaluation() returned error
519: in a compiled program, analyse() caught this error twice and randomly aborted
520: with a segmentation error;
521: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
522: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
523: signals;
524: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
525: matrix.

544: format in FCH (file descriptor) and SCK (socket descriptor);
545: - debug routines are improved;
546: - PROCID is added;
547: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
548: and to not use swap;
1.26 bertrand 549: - major bug is fixed in sql support. SQL connections were closed in all chield
550: process;
551: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
552: discovered in Solaris thread safe allocators (libmalloc and libumem) that
553: are first fit class allocators. Solaris libmtmalloc works better and is
554: a best fit class allocator but its performance is poor than ptmalloc3

559: caught);
560: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
561: created by SPAWN;
562: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute

568: This bug only occurs when RPL/2 tries to create a shared or static variable
569: from an expression;
570: - major bug is fixed in copie_etat_processus(). A field that contains
571: information about shared variable was not copied to new processus structure;
1.19 bertrand 572: - some little memory leaks are fixed in evaluation(), recherche_type() and
573: sequenceur(). They only occured when syntax error were caught;
574: - IMPLICIT causes execution error instead system error;

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

788: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
789: can call twice CSTOP without RSTOP;
790: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
791: SMPHRTRYDECR, SMPHGETV).
792: * Fri Jul 24 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.4 (RPL/2)
793: - semaphore is added in interruptions.c to avoid segmentation fault when STOP

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

800: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
801: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
802: process termination);
803: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
804: its parent);

812: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
813: - FORTRAN 77 file management subroutines are rewritten in pure C due to
814: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
815: in some cases (gcc/gfortran/libc/OS and arch conjonction);
816: - a memory leak is fixed in REMOVE intrinsic;
817: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
818: and due to a libmysqlclient that is not thread safe).

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

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

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

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

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

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

990: - FUSE, RFUSE and CLRFUSE have been added;
991: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
992: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
993: workaround for this major bug. Nevertheless, all others capabilities seems to
994: work fine;
995: - '->' is modified to return error when program tries to initialiaze two

1027: time signals have been removed;
1028: - major bugs are fixed in multitasking (mutex trouble _and_ segmentation fault);
1029: - minor bug is fixed in STR->. STR-> could return a system error instead an
1030: execution one;
1031: - first bug due to new garbage collector is fixed in '+' ({ } { } +) and in
1032: '-' intrinsics;
1033: - PostgreSQL support is written.

1036: { "mysql:iso-8859-1" "server" "database" ... };
1037: - major bug is fixed un analyse_algebrique(). When DISP printed an algebraic
1038: object, 'DISP()' was pushed in stack;
1039: - same major bug is fixed in <, >, <=, >= and <>;
1040: - major bug fixed in formateur() (segfault when a symbol is used without "'");
1041: - major bug is fixed in DUPN intrinsic;
1042: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
1043: before starting interrupt evaluation;
1044: - -f parameter is added when iconv is called;
1045: - as old file program was bugged, a new option is added to configure script.
1046: When configure is called with --disable-encoding-autodetection, make does not
1047: try to detect source encoding. Please, do not use if RPL/2 can be built
1048: without this option !
1049: - new garbage collector (and more efficient) is written;
1050: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1051: not support real time signals, RPL/2 cannot use multitasking functions;
1052: - error returned by preprocessor are now catched by RPL/2;
1053: - -p option is added. With this option, all scripts are compiled before
1054: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
1055: 40% faster;
1056: - read and write operations in pipe() are rewritten to be sure that such
1057: operations are atomic;

1257: - variable management routines have been rewritten. The new ones are
1258: uncompatible with the old ones. Before these changes, a local variable
1259: was exported to a child subroutine, but cannot be modified into this
1260: child subroutine. Now, a local variable is accessible only in its subroutine;
1261: - SAVE intrinsic is added to manipulate global variables;

1583: - NOT is not correctly formatted in formateur.c:
1584: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1585: with a NOTZ function !
1586: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1589: - RPL/2 is tested with efence and valgrind;
1590: - configure.in script is modified;
1591: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1652: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1653: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1654: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1675: statistical variable, or "DISABLED" if its type is not one of the type of
1676: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1677: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1678: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1679: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1680: disabled. Arguments of EXTERNAL are case sensitive because the external
1681: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1682: of known external functions but add the new list to the last. { "all" }
1683: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1684: external names of the known functions;
1685: - mkrplso.in is modified.
1686: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1700: VISIT does not find a name in level 1;
1701: - configure.in script is modified to add a new test (--enable-debug
1702: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1703: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1704: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1705: 'MATRIX' { 2 2 3 } GETR;
1706: - LOGSCALE intrinsic is improved and now, it can be used as
1707: { "main" "auxiliary" X Y } LOGSCALE;
1708: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1709: same than AXES:
1710: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1711: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1712: { { -10 10 } "automatic" } SCALE.
1713: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1714: because it changes only the dimension of the screen. To have a logarithmic
1715: scale, you must use LOGSCALE intrinsic:
1716: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1717: screen on second scale;
1718: - { X X } autoscale and { Y Y } logscale are now invalid;
1719: - *D is added (depth multiplication, for 3D graphics);
1720: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1721: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1722: - a major bug is fixed in GETI instrinsic when it is used with a name
1723: that contains a matrix or a vector (bad upper bounds conditions in
1724: incrementation);
1725: - DISP intrinsic now uses the 33-th flag. When it is not set
1726: (default), a final carriage return is sent to the terminal;
1727: - AXES intrinsic only takes a list that can contains the keywork
1728: "main" or "auxiliary". Before this modification, this keyword was in
1729: the first stack level;
1730: - vim syntax file is upgraded;
1731: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1732: option;
1733: - LAST is now disabled in the main loop of INT intrinsic;
1734: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1735: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1736: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1737: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1738: in 0);
1739: - LAST is disabled in the main loop of DRAW intrinsic;
1740: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1741: evaluation of an equation, the system stack is returned corrupted to the
1742: sequencer;
1743: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1744: of a loop are not integer or real.
1745: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1746: - the compilation stage aborts with an error message when two definitions
1747: have the same name. To improve the compilation() subroutine, I have to
1748: add some tests in gestion_variables.c;
1749: - recherche_type() subroutine ad some other connex subroutines are improved.
1750: Now, some syntax errors about object are caught and do not perform sequencer
1751: hangup;
1752: - readline is upgraded (minor compilation bug with recent gcc);
1753: - Makefile.am's and configure.in scripts are improved.
1754: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1755: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1756: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1757: the boxwidth, 1 by default);
1758: - recherche_type() is rewritten to be faster;
1759: - gsl is upgraded (release 1.3);
1760: - ncurses is upgraded and patched (release 5.3);
1761: - recherche_instruction_suivante() is fixed (string research with included
1762: '"') and rewritten to be faster;
1763: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1764: segfault.
1765: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1773: - a minor bug is fixed in evaluation subroutine;
1774: - vim syntax file is improved;
1775: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
