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

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

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

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

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

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

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

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

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

769: - gsl is upgraded to 1.13.
770: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
771: - pipe() is overwritten by a macro to avoid a system error. Communication
772: between process are done with pipes and these pipes are managed by a
773: specific asynchrone thread. If a script try to create more threads than
774: management thread can destroy, you can quickly achieve maximum number of
775: opened files and pipe() shall return a system error. This macro tries to create
776: pipes. If pipe() function returns an error, macro waits and retries. If
777: number of retries is greater than a hardcoded value, macro returns an error;
778: - major bug (deadlock) is fixed in process and thread management. I hope
779: this bug shall be the last one;
780: - major bug is fixed in DET intrinsic (determinant was computed without LU
781: diagonalization);
782: - SWAPCNTXT is added;
783: - minor bug is fixed in Makefile.am (licences rule).
784: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
785: - some bugfixes are added in process management;
786: - all process management is rewritten to avoid usage of defunct process
787: or thread number;
788: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
789: was called before a pending interruption5 (SIGFSTOP), signal handler uses
790: a freed semaphore and corrupts heap;
791: - CLRERR is added to erase previous errors;
792: - ERRN and ERRM return exception message and number;
793: - major bug is fixed in interruptions.c. All signal are now bufferised
794: when semaphore_liste_threads is null to avoid deadlock. This bug only
795: occured when STOP was sent to a dying thread or process (when this thread or
796: process was running retrait_thread());
797: - matrix rank is computed before matrix inversion;
798: - file locks are added to stdin and stdout. stderr is not locked because
799: all messages written by signal handlers are sent to stderr;
800: - configure.in script is modified to test gcc version and avoid a bug in
801: gcc older than 4.4;
802: - some benchmarks have been done :

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

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

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

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

1089: before starting interrupt evaluation;
1090: - -f parameter is added when iconv is called;
1091: - as old file program was bugged, a new option is added to configure script.
1092: When configure is called with --disable-encoding-autodetection, make does not

1132: than 1E6;
1133: - numeric and character formats are now tested;
1134: - -A flag is added. -A is used to give command line parameters to main
1135: routine. Example:

1244: - HELP function is rewritten to be more friendly (a la OpenVMS);
1245: - external wrapper (rplplot) is written to force usage of gnuplot provided
1246: by RPL/2 if it is built during build process. If this build does not exist,
1247: it tries to launch regular gnuplot;
1248: - gnuplot is added to source tree to avoid some trouble between preinstalled
1249: gnuplot and release used by RPL/2. This addition to source tree is

1527: #!/usr/local/bin/rpl -c
1528:
1529: TEST
1530: <<
1531: 'X' indep

1628: fine...);
1629: - NOT is not correctly formatted in formateur.c:
1630: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1631: with a NOTZ function !
1632: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1635: - RPL/2 is tested with efence and valgrind;
1636: - configure.in script is modified;
1637: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1698: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1699: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1700: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1717: - SCLS is added;
1718: - DRWS now uses COLS to draw 2D graphics;
1719: - PPAR and SPAR are written. SPAR returns a list that contains the
1720: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1721: statistical variable, or "DISABLED" if its type is not one of the type of
1722: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1723: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1724: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1725: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1726: disabled. Arguments of EXTERNAL are case sensitive because the external
1727: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1728: of known external functions but add the new list to the last. { "all" }
1729: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1730: external names of the known functions;
1731: - mkrplso.in is modified.
1732: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1733: - vim syntax file is upgraded;
1734: - a minor mistake is fixed in recherche_instruction_suivante();

1746: VISIT does not find a name in level 1;
1747: - configure.in script is modified to add a new test (--enable-debug
1748: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1749: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1750: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1751: 'MATRIX' { 2 2 3 } GETR;
1752: - LOGSCALE intrinsic is improved and now, it can be used as
1753: { "main" "auxiliary" X Y } LOGSCALE;
1754: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1755: same than AXES:
1756: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1757: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1758: { { -10 10 } "automatic" } SCALE.
1759: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1760: because it changes only the dimension of the screen. To have a logarithmic
1761: scale, you must use LOGSCALE intrinsic:
1762: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1763: screen on second scale;
1764: - { X X } autoscale and { Y Y } logscale are now invalid;
1765: - *D is added (depth multiplication, for 3D graphics);
1766: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1767: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1768: - a major bug is fixed in GETI instrinsic when it is used with a name
1769: that contains a matrix or a vector (bad upper bounds conditions in
1770: incrementation);
1771: - DISP intrinsic now uses the 33-th flag. When it is not set
1772: (default), a final carriage return is sent to the terminal;
1773: - AXES intrinsic only takes a list that can contains the keywork
1774: "main" or "auxiliary". Before this modification, this keyword was in
1775: the first stack level;
1776: - vim syntax file is upgraded;
1777: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1778: option;
1779: - LAST is now disabled in the main loop of INT intrinsic;
1780: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1781: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1782: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1783: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1784: in 0);
1785: - LAST is disabled in the main loop of DRAW intrinsic;
1786: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1787: evaluation of an equation, the system stack is returned corrupted to the
1788: sequencer;
1789: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1790: of a loop are not integer or real.
1791: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1792: - the compilation stage aborts with an error message when two definitions
1793: have the same name. To improve the compilation() subroutine, I have to
1794: add some tests in gestion_variables.c;
1795: - recherche_type() subroutine ad some other connex subroutines are improved.
1796: Now, some syntax errors about object are caught and do not perform sequencer
1797: hangup;
1798: - readline is upgraded (minor compilation bug with recent gcc);
1799: - Makefile.am's and configure.in scripts are improved.
1800: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1801: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1802: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1803: the boxwidth, 1 by default);
1804: - recherche_type() is rewritten to be faster;
1805: - gsl is upgraded (release 1.3);
1806: - ncurses is upgraded and patched (release 5.3);
1807: - recherche_instruction_suivante() is fixed (string research with included
1808: '"') and rewritten to be faster;

1819: - a minor bug is fixed in evaluation subroutine;
1820: - vim syntax file is improved;
1821: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1822: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1823: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1824: is a quick and dirty workaround...);
1825: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1826: - rplconvert is improved.

1908: deleted too!;
1909: - configure script is improved (and it seems to be good ;-) );

1926: signal is an asynchonous "HALT" command;
1927: - SIGINT (CTRL+C) variables stack corruption is fixed;
1928: - IFERR seems to be fixed (in equation evaluation routine);

1936: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1937: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1938: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1939:
1940: Newton:[~/rpl/rpl] > time make install
1941: ...
1942: real 338m39.623s
1943: user 324m32.290s
