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

430: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
431: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
432: corruption. As internal memory management have been improved, a best fit
433: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 434: - gnuplot is upgraded to 4.4.1;
435: - deadlock is fixed in signal handlers: same mutex was used in standard

457: systems that does not provide correct POSIX or SysV semaphores subsystem;
458: - a dirty but not quick patch is written to workaround broken siginfo
459: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 460: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process

492: caught;
493: - major bug is fixed in analyse() subroutine. When evaluation() returned error
494: in a compiled program, analyse() caught this error twice and randomly aborted
495: with a segmentation error;
496: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
497: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
498: signals;

672: made by blocks (1024 bytes). When an incomplete multibyte sequence is
673: encountered at end of block, subroutine aborts with an execution error;
674: - major bug is fixed in OPEN (TCP/IPv4 sockets).
675: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
676: - DISP now locks stdout;
677: - rpliconv is added to replace standard iconv provided by operating system.
678: Indeed, conversion between different encodages requires transliteration
679: that is not offered by some iconv utility;
680: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
681: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
682: not be found), SYSEVAL enters in a dead lock;
683: - fprintf is replaced by some functions that allow transliterations between
684: locales;
685: - '"' can now be used in strings ("\"");
686: - iconv is called with -c in preprocessor stage. It is done to write
687: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
688: - double free is fixed in liberation() (type SQL, only occurs when locale is
689: set);
690: - LOCALIZATION, UCASE and LCASE are added;
691: - major bug is fixed in EXIT intrinsic that was able to return a false
692: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
693: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
694: used in onLoading from shared library, USE was pushed on stack as algebraic
695: expression;
696: - libiconv is upgraded to 1.13.1;
697: - gnuplot is upgraded to 4.2.6;
698: - gsl is upgraded to 1.13.
699: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
700: - pipe() is overwritten by a macro to avoid a system error. Communication
701: between process are done with pipes and these pipes are managed by a
702: specific asynchrone thread. If a script try to create more threads than
703: management thread can destroy, you can quickly achieve maximum number of
704: opened files and pipe() shall return a system error. This macro tries to create
705: pipes. If pipe() function returns an error, macro waits and retries. If
706: number of retries is greater than a hardcoded value, macro returns an error;
707: - major bug (deadlock) is fixed in process and thread management. I hope
708: this bug shall be the last one;
709: - major bug is fixed in DET intrinsic (determinant was computed without LU
710: diagonalization);
711: - SWAPCNTXT is added;
712: - minor bug is fixed in Makefile.am (licences rule).
713: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
714: - some bugfixes are added in process management;
715: - all process management is rewritten to avoid usage of defunct process
716: or thread number;
717: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
718: was called before a pending interruption5 (SIGFSTOP), signal handler uses
719: a freed semaphore and corrupts heap;
720: - CLRERR is added to erase previous errors;
721: - ERRN and ERRM return exception message and number;
722: - major bug is fixed in interruptions.c. All signal are now bufferised
723: when semaphore_liste_threads is null to avoid deadlock. This bug only
724: occured when STOP was sent to a dying thread or process (when this thread or
725: process was running retrait_thread());
726: - matrix rank is computed before matrix inversion;
727: - file locks are added to stdin and stdout. stderr is not locked because
728: all messages written by signal handlers are sent to stderr;
729: - configure.in script is modified to test gcc version and avoid a bug in
730: gcc older than 4.4;
731: - some benchmarks have been done :

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

775: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
776: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
777: process termination);
778: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
779: its parent);
780: - a mutex to protect fork() syscall is added;

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

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

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

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

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

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

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

1018: before starting interrupt evaluation;
1019: - -f parameter is added when iconv is called;
1020: - as old file program was bugged, a new option is added to configure script.
1021: When configure is called with --disable-encoding-autodetection, make does not
1022: try to detect source encoding. Please, do not use if RPL/2 can be built
1023: without this option !
1024: - new garbage collector (and more efficient) is written;
1025: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1026: not support real time signals, RPL/2 cannot use multitasking functions;
1027: - error returned by preprocessor are now catched by RPL/2;
1028: - -p option is added. With this option, all scripts are compiled before
1029: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run

1150: - minor bug is fixed in recherche_type(). Don't forget that space
1151: are not significant in algebraic expression:
1152: '12 3+ 12 X' is the same expression than '123+12X';
1153: - src/Makefile.am is modified to avoid double compilation process;
1154: - --enable-final-run-path is added to configure.in script;

1173: - HELP function is rewritten to be more friendly (a la OpenVMS);
1174: - external wrapper (rplplot) is written to force usage of gnuplot provided
1175: by RPL/2 if it is built during build process. If this build does not exist,
1176: it tries to launch regular gnuplot;
1177: - gnuplot is added to source tree to avoid some trouble between preinstalled
1178: gnuplot and release used by RPL/2. This addition to source tree is
1179: required by some incompatibility between gnuplot releases;

1185: not writable;
1186: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1187: error scrutation.

1229: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1230: versions of PROTECT and UNPROTECT that only deal with global variables
1231: (see RCL/SAVE);
1232: - variable management routines have been rewritten. The new ones are
1233: uncompatible with the old ones. Before these changes, a local variable
1234: was exported to a child subroutine, but cannot be modified into this
1235: child subroutine. Now, a local variable is accessible only in its subroutine;
1236: - SAVE intrinsic is added to manipulate global variables;

1557: fine...);
1558: - NOT is not correctly formatted in formateur.c:
1559: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1560: with a NOTZ function !
1561: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1564: - RPL/2 is tested with efence and valgrind;
1565: - configure.in script is modified;
1566: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1627: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1628: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1629: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1646: - SCLS is added;
1647: - DRWS now uses COLS to draw 2D graphics;
1648: - PPAR and SPAR are written. SPAR returns a list that contains the
1649: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1650: statistical variable, or "DISABLED" if its type is not one of the type of
1651: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1652: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1653: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1654: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1655: disabled. Arguments of EXTERNAL are case sensitive because the external
1656: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1657: of known external functions but add the new list to the last. { "all" }
1658: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1659: external names of the known functions;
1660: - mkrplso.in is modified.
1661: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1662: - vim syntax file is upgraded;
1663: - a minor mistake is fixed in recherche_instruction_suivante();
1664: - some minor memory leaks are fixed in recherche_type() function. They only

1674: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1675: VISIT does not find a name in level 1;
1676: - configure.in script is modified to add a new test (--enable-debug
1677: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1678: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1679: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1680: 'MATRIX' { 2 2 3 } GETR;
1681: - LOGSCALE intrinsic is improved and now, it can be used as
1682: { "main" "auxiliary" X Y } LOGSCALE;
1683: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1684: same than AXES:
1685: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1686: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1687: { { -10 10 } "automatic" } SCALE.
1688: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1689: because it changes only the dimension of the screen. To have a logarithmic
1690: scale, you must use LOGSCALE intrinsic:
1691: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1692: screen on second scale;
1693: - { X X } autoscale and { Y Y } logscale are now invalid;
1694: - *D is added (depth multiplication, for 3D graphics);
1695: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1696: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1697: - a major bug is fixed in GETI instrinsic when it is used with a name
1698: that contains a matrix or a vector (bad upper bounds conditions in
1699: incrementation);
1700: - DISP intrinsic now uses the 33-th flag. When it is not set
1701: (default), a final carriage return is sent to the terminal;
1702: - AXES intrinsic only takes a list that can contains the keywork
1703: "main" or "auxiliary". Before this modification, this keyword was in
1704: the first stack level;
1705: - vim syntax file is upgraded;
1706: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1707: option;
1708: - LAST is now disabled in the main loop of INT intrinsic;
1709: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1710: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1711: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1712: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1713: in 0);
1714: - LAST is disabled in the main loop of DRAW intrinsic;
1715: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1716: evaluation of an equation, the system stack is returned corrupted to the
1717: sequencer;
1718: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1719: of a loop are not integer or real.
1720: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1728: - Makefile.am's and configure.in scripts are improved.
1729: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1730: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1731: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1733: - recherche_type() is rewritten to be faster;
1734: - gsl is upgraded (release 1.3);
1735: - ncurses is upgraded and patched (release 5.3);
1736: - recherche_instruction_suivante() is fixed (string research with included
1737: '"') and rewritten to be faster;

1748: - a minor bug is fixed in evaluation subroutine;
1749: - vim syntax file is improved;
1750: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1751: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1752: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1753: is a quick and dirty workaround...);
1754: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1755: - rplconvert is improved.
1756: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
