387: 18446744072742037448 is converted into real as value cannot be stored in
388: RPL/2 integer type;
389: - WFSOCK is modified to handle unconnected sockets;
390: - REGEX is added;
391: - RESTART is added (execvp() on main RPL/2 process);
392: - copie_objet() now returns same MTX (struct_mutex) even if caller wait for
393: a real copy. Now, struct_mutex contains locks owner. On Linux or Solaris (for
394: example), it is possible to lock mutex from a thread and unlock the same mutex
395: from another thread. On NetBSD, system crashes.

469: - major bug is fixed in STD format (1E7 sq prints 1);
470: - major bug is fixed in READ intrinsic (socket). This bug was introduced
471: by a new feature in glibc.
472: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
473: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
474: "ALL" IMPLICIT when it runs in interactive mode;
475: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
476: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
477: to use SAVE to manipulate global variables;
478: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
479: subroutines;
480: - fix major memory access violation in evaluation subroutine. Only occurs
481: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
482: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
483: when X was a vector or a table.
484: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

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

534: this bug, SIGINJECT signal is not sent by child process but by control thread
535: in parent process;
536: - minor bug is fixed in data injection (POKE) that does not work as expected
537: when child process is protected by NRPROC.
538: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
539: - --enable-sysv-sems is added to configure script to use SystemV semaphores
540: functions instead of POSIX functions. This function is disabled or forced on
541: systems that does not provide correct POSIX or SysV semaphores subsystem;
542: - a dirty but not quick patch is written to workaround broken siginfo
543: structures. This patch has been successfully tested. It uses a segment of
544: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
545: (Unix PID);
546: - some OpenBSD's hacks are added;
547: - broken siginfo->si_pid field is now checked by configure script;

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

573: - BACKTRACE intrinsic is added;
574: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
575: when this structure is included in IFERR/THEN/END structure and when an error is
576: caught;
577: - major bug is fixed in analyse() subroutine. When evaluation() returned error
578: in a compiled program, analyse() caught this error twice and randomly aborted
579: with a segmentation error;
580: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
581: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
582: signals;
583: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
584: matrix.

603: format in FCH (file descriptor) and SCK (socket descriptor);
604: - debug routines are improved;
605: - PROCID is added;
606: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
607: and to not use swap;
608: - major bug is fixed in sql support. SQL connections were closed in all chield
609: process;
610: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
611: discovered in Solaris thread safe allocators (libmalloc and libumem) that
612: are first fit class allocators. Solaris libmtmalloc works better and is
613: a best fit class allocator but its performance is poor than ptmalloc3
614: performance;
615: - major bug is fixed in ROW+ intrinsic (new row was not added where it
616: should);
617: - minor bugs are fixed in interruptions.c (semaphores values when error is
618: caught);
619: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
620: created by SPAWN;

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

691: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
692: on a non recoverable system error;
693: - openssl and sqlite3 libraries are added;

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

767: - fprintf is replaced by some functions that allow transliterations between
768: locales;
769: - '"' can now be used in strings ("\"");
770: - iconv is called with -c in preprocessor stage. It is done to write
771: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
772: - double free is fixed in liberation() (type SQL, only occurs when locale is
773: set);
774: - LOCALIZATION, UCASE and LCASE are added;
775: - major bug is fixed in EXIT intrinsic that was able to return a false
776: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
777: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
778: used in onLoading from shared library, USE was pushed on stack as algebraic
779: expression;
780: - libiconv is upgraded to 1.13.1;
781: - gnuplot is upgraded to 4.2.6;
782: - gsl is upgraded to 1.13.
783: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
784: - pipe() is overwritten by a macro to avoid a system error. Communication
785: between process are done with pipes and these pipes are managed by a
786: specific asynchrone thread. If a script try to create more threads than
787: management thread can destroy, you can quickly achieve maximum number of
788: opened files and pipe() shall return a system error. This macro tries to create
789: pipes. If pipe() function returns an error, macro waits and retries. If
790: number of retries is greater than a hardcoded value, macro returns an error;
791: - major bug (deadlock) is fixed in process and thread management. I hope
792: this bug shall be the last one;
793: - major bug is fixed in DET intrinsic (determinant was computed without LU
794: diagonalization);
795: - SWAPCNTXT is added;
796: - minor bug is fixed in Makefile.am (licences rule).
797: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
798: - some bugfixes are added in process management;
799: - all process management is rewritten to avoid usage of defunct process
800: or thread number;
801: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
802: was called before a pending interruption5 (SIGFSTOP), signal handler uses
803: a freed semaphore and corrupts heap;
804: - CLRERR is added to erase previous errors;
805: - ERRN and ERRM return exception message and number;
806: - major bug is fixed in interruptions.c. All signal are now bufferised
807: when semaphore_liste_threads is null to avoid deadlock. This bug only
808: occured when STOP was sent to a dying thread or process (when this thread or
809: process was running retrait_thread());
810: - matrix rank is computed before matrix inversion;
811: - file locks are added to stdin and stdout. stderr is not locked because
812: all messages written by signal handlers are sent to stderr;
813: - configure.in script is modified to test gcc version and avoid a bug in
814: gcc older than 4.4;
815: - some benchmarks have been done :

832: - SVL and SVD are added;
833: - COND and RANK are added;
834: - DIAG-> and ->DIAG are added;
835: - major bug is fixed in DET intrinsic. DET is rewritten to avoid usage of

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

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

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

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

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

954: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
955: that all programs that worked with old SQL intrinsic can now work with
956: SQLQUERY. With all new programs, you can open a real connection to databases;
957: - NRPROC is added. This new intrinsic is used to catch error from child
958: process. Without NRPROC, any errors returned by child process cause
959: main process to abort;
960: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
961: starts a new process). There are no mutexes in RPL/2 because all spawned process
962: use specific context. Nevertheless, shared variables and associated mutexes
963: should be added;
964: - -D flag and DAEMONIZE intrinsic have been added;
965: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

1034: nullified lists;
1035: - rplexternals.h is modified and improved;
1036: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and

1052: workaround for this major bug. Nevertheless, all others capabilities seems to
1053: work fine;
1054: - '->' is modified to return error when program tries to initialiaze two

1099: - major bug fixed in formateur() (segfault when a symbol is used without "'");
1100: - major bug is fixed in DUPN intrinsic;
1101: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
1102: before starting interrupt evaluation;
1103: - -f parameter is added when iconv is called;
1104: - as old file program was bugged, a new option is added to configure script.
1105: When configure is called with --disable-encoding-autodetection, make does not

1107: without this option !
1108: - new garbage collector (and more efficient) is written;
1109: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1110: not support real time signals, RPL/2 cannot use multitasking functions;
1111: - error returned by preprocessor are now catched by RPL/2;
1112: - -p option is added. With this option, all scripts are compiled before
1113: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run

1145: than 1E6;
1146: - numeric and character formats are now tested;
1147: - -A flag is added. -A is used to give command line parameters to main

1234: - minor bug is fixed in recherche_type(). Don't forget that space
1235: are not significant in algebraic expression:
1236: '12 3+ 12 X' is the same expression than '123+12X';
1237: - src/Makefile.am is modified to avoid double compilation process;
1238: - --enable-final-run-path is added to configure.in script;

1256: functions were case unsensitive when they were evaluated from RPN expressions;
1257: - HELP function is rewritten to be more friendly (a la OpenVMS);
1258: - external wrapper (rplplot) is written to force usage of gnuplot provided
1259: by RPL/2 if it is built during build process. If this build does not exist,
1260: it tries to launch regular gnuplot;
1261: - gnuplot is added to source tree to avoid some trouble between preinstalled
1262: gnuplot and release used by RPL/2. This addition to source tree is
1263: required by some incompatibility between gnuplot releases;

1269: not writable;
1270: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1271: error scrutation.

1312: - PROTECT and UNPROTECT are added to protect variables against write
1313: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1314: versions of PROTECT and UNPROTECT that only deal with global variables
1315: (see RCL/SAVE);
1316: - variable management routines have been rewritten. The new ones are
1317: uncompatible with the old ones. Before these changes, a local variable
1318: was exported to a child subroutine, but cannot be modified into this
1319: child subroutine. Now, a local variable is accessible only in its subroutine;
1320: - SAVE intrinsic is added to manipulate global variables;

1641: fine...);
1642: - NOT is not correctly formatted in formateur.c:
1643: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1644: with a NOTZ function !
1645: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1648: - RPL/2 is tested with efence and valgrind;
1649: - configure.in script is modified;
1650: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1711: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1712: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1713: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1730: - SCLS is added;
1731: - DRWS now uses COLS to draw 2D graphics;
1732: - PPAR and SPAR are written. SPAR returns a list that contains the
1733: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1734: statistical variable, or "DISABLED" if its type is not one of the type of
1735: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1736: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1737: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1738: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1739: disabled. Arguments of EXTERNAL are case sensitive because the external
1740: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1741: of known external functions but add the new list to the last. { "all" }
1742: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1743: external names of the known functions;
1744: - mkrplso.in is modified.
1745: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1759: VISIT does not find a name in level 1;
1760: - configure.in script is modified to add a new test (--enable-debug
1761: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1762: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1763: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1764: 'MATRIX' { 2 2 3 } GETR;
1765: - LOGSCALE intrinsic is improved and now, it can be used as
1766: { "main" "auxiliary" X Y } LOGSCALE;
1767: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1768: same than AXES:
1769: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1770: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1771: { { -10 10 } "automatic" } SCALE.
1772: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1773: because it changes only the dimension of the screen. To have a logarithmic
1774: scale, you must use LOGSCALE intrinsic:
1775: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1776: screen on second scale;
1777: - { X X } autoscale and { Y Y } logscale are now invalid;
1778: - *D is added (depth multiplication, for 3D graphics);
1779: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1780: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1781: - a major bug is fixed in GETI instrinsic when it is used with a name
1782: that contains a matrix or a vector (bad upper bounds conditions in
1783: incrementation);
1784: - DISP intrinsic now uses the 33-th flag. When it is not set
1785: (default), a final carriage return is sent to the terminal;
1786: - AXES intrinsic only takes a list that can contains the keywork
1787: "main" or "auxiliary". Before this modification, this keyword was in
1788: the first stack level;
1789: - vim syntax file is upgraded;
1790: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1791: option;
1792: - LAST is now disabled in the main loop of INT intrinsic;
1793: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1794: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1795: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1796: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1797: in 0);
1798: - LAST is disabled in the main loop of DRAW intrinsic;
1799: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1800: evaluation of an equation, the system stack is returned corrupted to the
1801: sequencer;
1802: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1803: of a loop are not integer or real.
1804: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1809: Now, some syntax errors about object are caught and do not perform sequencer
1810: hangup;
1811: - readline is upgraded (minor compilation bug with recent gcc);
1812: - Makefile.am's and configure.in scripts are improved.
1813: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1814: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1815: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1817: - recherche_type() is rewritten to be faster;
1818: - gsl is upgraded (release 1.3);
1819: - ncurses is upgraded and patched (release 5.3);
1820: - recherche_instruction_suivante() is fixed (string research with included
1821: '"') and rewritten to be faster;

1832: - a minor bug is fixed in evaluation subroutine;
1833: - vim syntax file is improved;
1834: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1835: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1836: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1837: is a quick and dirty workaround...);
1838: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1839: - rplconvert is improved.

1952:
1953: Newton:[~/rpl/rpl] > time make install
