454: - major bug is fixed in STD format (1E7 sq prints 1);
455: - major bug is fixed in READ intrinsic (socket). This bug was introduced
456: by a new feature in glibc.
457: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
458: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
459: "ALL" IMPLICIT when it runs in interactive mode;
460: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
461: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
462: to use SAVE to manipulate global variables;
463: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
464: subroutines;
465: - fix major memory access violation in evaluation subroutine. Only occurs
466: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
467: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
468: when X was a vector or a table.

498: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
499: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
500: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
501: corruption. As internal memory management have been improved, a best fit
502: allocator like ptmalloc3 is not required anymore;
503: - gnuplot is upgraded to 4.4.1;
504: - deadlock is fixed in signal handlers: same mutex was used in standard
505: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
506: and signal handlers. A new signal handler specific mutex is added;
507: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
508: that has to be evaluated by ->NUM;
509: - rplfile build process is modify to be sure that rplfile is not modified
510: after rpl build stage (to be sure that rplfile checksum is not modified after

518: parent process was not interrupted if it is not group master process. To fix
519: this bug, SIGINJECT signal is not sent by child process but by control thread
520: in parent process;
521: - minor bug is fixed in data injection (POKE) that does not work as expected
522: when child process is protected by NRPROC.
523: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
524: - --enable-sysv-sems is added to configure script to use SystemV semaphores
525: functions instead of POSIX functions. This function is disabled or forced on
526: systems that does not provide correct POSIX or SysV semaphores subsystem;
527: - a dirty but not quick patch is written to workaround broken siginfo
528: structures. This patch has been successfully tested. It uses a segment of
529: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
530: (Unix PID);
531: - some OpenBSD's hacks are added;
532: - broken siginfo->si_pid field is now checked by configure script;

550: Level 0 and 1 variables adresses were swapped when a global variable masked
551: a name of RPL/2 routine;
552: - major bug is fixed in global variable creation subroutine. When a global
553: variable was created and when a local variable existed with the same name,
554: computed address of global variable was wrong;
555: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
556: is forced in front of all libraries.

558: - BACKTRACE intrinsic is added;
559: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
560: when this structure is included in IFERR/THEN/END structure and when an error is
561: caught;
562: - major bug is fixed in analyse() subroutine. When evaluation() returned error
563: in a compiled program, analyse() caught this error twice and randomly aborted
564: with a segmentation error;
565: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
566: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
567: signals;
568: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
569: matrix.

588: format in FCH (file descriptor) and SCK (socket descriptor);
589: - debug routines are improved;
590: - PROCID is added;
591: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
592: and to not use swap;
593: - major bug is fixed in sql support. SQL connections were closed in all chield
594: process;
595: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
596: discovered in Solaris thread safe allocators (libmalloc and libumem) that
597: are first fit class allocators. Solaris libmtmalloc works better and is
598: a best fit class allocator but its performance is poor than ptmalloc3
599: performance;
600: - major bug is fixed in ROW+ intrinsic (new row was not added where it
601: should);
602: - minor bugs are fixed in interruptions.c (semaphores values when error is
603: caught);
604: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
605: created by SPAWN;

615: information about shared variable was not copied to new processus structure;
616: - some little memory leaks are fixed in evaluation(), recherche_type() and
617: sequenceur(). They only occured when syntax error were caught;
618: - IMPLICIT causes execution error instead system error;
619: - Hurd support is improved but currently broken because Hurd does not support
620: SIG_INFO. Work in progress;
621: - OpenBSD specific support is removed from sources;
622: - support for Mac OS X and Windows/Cygwin is added.

676: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
677: on a non recoverable system error;
678: - openssl and sqlite3 libraries are added;
679: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

717: signals sent to main process were not caught because DAEMON did not replace
718: old pid by new one;
719: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
720: evaluation when an error is reported from a subroutine in another subroutine.
721: For example, error was not caught in following program when it is executed with

768: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
769: - pipe() is overwritten by a macro to avoid a system error. Communication
770: between process are done with pipes and these pipes are managed by a
771: specific asynchrone thread. If a script try to create more threads than
772: management thread can destroy, you can quickly achieve maximum number of
773: opened files and pipe() shall return a system error. This macro tries to create
774: pipes. If pipe() function returns an error, macro waits and retries. If
775: number of retries is greater than a hardcoded value, macro returns an error;
776: - major bug (deadlock) is fixed in process and thread management. I hope
777: this bug shall be the last one;
778: - major bug is fixed in DET intrinsic (determinant was computed without LU
779: diagonalization);
780: - SWAPCNTXT is added;
781: - minor bug is fixed in Makefile.am (licences rule).
782: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
783: - some bugfixes are added in process management;
784: - all process management is rewritten to avoid usage of defunct process
785: or thread number;
786: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
787: was called before a pending interruption5 (SIGFSTOP), signal handler uses
788: a freed semaphore and corrupts heap;
789: - CLRERR is added to erase previous errors;
790: - ERRN and ERRM return exception message and number;
791: - major bug is fixed in interruptions.c. All signal are now bufferised
792: when semaphore_liste_threads is null to avoid deadlock. This bug only
793: occured when STOP was sent to a dying thread or process (when this thread or
794: process was running retrait_thread());
795: - matrix rank is computed before matrix inversion;
796: - file locks are added to stdin and stdout. stderr is not locked because
797: all messages written by signal handlers are sent to stderr;
798: - configure.in script is modified to test gcc version and avoid a bug in
799: gcc older than 4.4;
800: - some benchmarks have been done :

872: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
873: process is killed;
874: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
875: know typeof() intrinsic function. This function is not standard but exists
876: under Sun Studio, gcc, and maybe some others compilers. If this function does
877: not exist on your compiler, you can change its definition by old one in
878: src/rpl.h;

901: deadlock when a huge amount of threads is launched);
902: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
903: arguments types are unsupported;
904: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

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

940: that all programs that worked with old SQL intrinsic can now work with
941: SQLQUERY. With all new programs, you can open a real connection to databases;
942: - NRPROC is added. This new intrinsic is used to catch error from child
943: process. Without NRPROC, any errors returned by child process cause
944: main process to abort;
945: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
946: starts a new process). There are no mutexes in RPL/2 because all spawned process
947: use specific context. Nevertheless, shared variables and associated mutexes
948: should be added;
949: - -D flag and DAEMONIZE intrinsic have been added;

1087: before starting interrupt evaluation;
1088: - -f parameter is added when iconv is called;
1089: - as old file program was bugged, a new option is added to configure script.
1090: When configure is called with --disable-encoding-autodetection, make does not

1130: than 1E6;
1131: - numeric and character formats are now tested;
1132: - -A flag is added. -A is used to give command line parameters to main
1133: routine. Example:

1219: - minor bug is fixed in recherche_type(). Don't forget that space
1220: are not significant in algebraic expression:
1221: '12 3+ 12 X' is the same expression than '123+12X';
1222: - src/Makefile.am is modified to avoid double compilation process;
1223: - --enable-final-run-path is added to configure.in script;

1242: - HELP function is rewritten to be more friendly (a la OpenVMS);
1243: - external wrapper (rplplot) is written to force usage of gnuplot provided
1244: by RPL/2 if it is built during build process. If this build does not exist,
1245: it tries to launch regular gnuplot;
1246: - gnuplot is added to source tree to avoid some trouble between preinstalled
1247: gnuplot and release used by RPL/2. This addition to source tree is

1301: - variable management routines have been rewritten. The new ones are
1302: uncompatible with the old ones. Before these changes, a local variable
1303: was exported to a child subroutine, but cannot be modified into this
1304: child subroutine. Now, a local variable is accessible only in its subroutine;

1626: fine...);
1627: - NOT is not correctly formatted in formateur.c:
1628: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1629: with a NOTZ function !
1630: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1633: - RPL/2 is tested with efence and valgrind;
1634: - configure.in script is modified;
1635: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1696: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1697: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1698: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1715: - SCLS is added;
1716: - DRWS now uses COLS to draw 2D graphics;
1717: - PPAR and SPAR are written. SPAR returns a list that contains the
1718: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1719: statistical variable, or "DISABLED" if its type is not one of the type of
1720: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1721: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1722: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1723: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1724: disabled. Arguments of EXTERNAL are case sensitive because the external
1725: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1726: of known external functions but add the new list to the last. { "all" }
1727: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1728: external names of the known functions;
1729: - mkrplso.in is modified.
1730: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1731: - vim syntax file is upgraded;
1732: - a minor mistake is fixed in recherche_instruction_suivante();

1744: VISIT does not find a name in level 1;
1745: - configure.in script is modified to add a new test (--enable-debug
1746: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1747: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1748: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1749: 'MATRIX' { 2 2 3 } GETR;
1750: - LOGSCALE intrinsic is improved and now, it can be used as
1751: { "main" "auxiliary" X Y } LOGSCALE;
1752: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1753: same than AXES:
1754: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1755: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1756: { { -10 10 } "automatic" } SCALE.
1757: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1758: because it changes only the dimension of the screen. To have a logarithmic
1759: scale, you must use LOGSCALE intrinsic:
1760: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1761: screen on second scale;
1762: - { X X } autoscale and { Y Y } logscale are now invalid;
1763: - *D is added (depth multiplication, for 3D graphics);
1764: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1765: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1766: - a major bug is fixed in GETI instrinsic when it is used with a name
1767: that contains a matrix or a vector (bad upper bounds conditions in
1768: incrementation);
1769: - DISP intrinsic now uses the 33-th flag. When it is not set
1770: (default), a final carriage return is sent to the terminal;
1771: - AXES intrinsic only takes a list that can contains the keywork
1772: "main" or "auxiliary". Before this modification, this keyword was in
1773: the first stack level;
1774: - vim syntax file is upgraded;
1775: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1776: option;
1777: - LAST is now disabled in the main loop of INT intrinsic;
1778: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1779: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1780: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1781: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1782: in 0);
1783: - LAST is disabled in the main loop of DRAW intrinsic;
1784: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1785: evaluation of an equation, the system stack is returned corrupted to the
1786: sequencer;
1787: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1788: of a loop are not integer or real.
1789: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1790: - the compilation stage aborts with an error message when two definitions
1791: have the same name. To improve the compilation() subroutine, I have to
1792: add some tests in gestion_variables.c;
1793: - recherche_type() subroutine ad some other connex subroutines are improved.
1794: Now, some syntax errors about object are caught and do not perform sequencer
1795: hangup;
1796: - readline is upgraded (minor compilation bug with recent gcc);
1797: - Makefile.am's and configure.in scripts are improved.
1798: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1799: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1800: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1801: the boxwidth, 1 by default);
1802: - recherche_type() is rewritten to be faster;
1803: - gsl is upgraded (release 1.3);
1804: - ncurses is upgraded and patched (release 5.3);
1805: - recherche_instruction_suivante() is fixed (string research with included
1806: '"') and rewritten to be faster;

1817: - a minor bug is fixed in evaluation subroutine;
1818: - vim syntax file is improved;
1819: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1820: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1821: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1822: is a quick and dirty workaround...);
1823: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1824: - rplconvert is improved.

1906: deleted too!;
1907: - configure script is improved (and it seems to be good ;-) );

1924: signal is an asynchonous "HALT" command;
1925: - SIGINT (CTRL+C) variables stack corruption is fixed;
1926: - IFERR seems to be fixed (in equation evaluation routine);

1934: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1935: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1936: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1937:
1938: Newton:[~/rpl/rpl] > time make install
1939: ...
1940: real 338m39.623s
1941: user 324m32.290s
