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

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

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

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

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

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

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

679: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
680: each execution (md5 and sha1 sums) to enhance security. If one of these tools
681: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
682: on a non recoverable system error;
683: - openssl and sqlite3 libraries are added;
684: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
685: variable indicates RPL/2 root directory. If it is not set, root path
686: is given by configure script (d_exec_path);

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

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

877: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
878: process is killed;
879: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
880: know typeof() intrinsic function. This function is not standard but exists
881: under Sun Studio, gcc, and maybe some others compilers. If this function does
882: not exist on your compiler, you can change its definition by old one in
883: src/rpl.h;
884: - fflush() can now be interrupted by signal (SunOS);
885: - fflush(NULL) is called before all fork() occurrences;

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

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

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

1042: workaround for this major bug. Nevertheless, all others capabilities seems to
1043: work fine;
1044: - '->' is modified to return error when program tries to initialiaze two

1092: before starting interrupt evaluation;
1093: - -f parameter is added when iconv is called;
1094: - as old file program was bugged, a new option is added to configure script.
1095: When configure is called with --disable-encoding-autodetection, make does not

1100: not support real time signals, RPL/2 cannot use multitasking functions;
1101: - error returned by preprocessor are now catched by RPL/2;
1102: - -p option is added. With this option, all scripts are compiled before
1103: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run

1135: than 1E6;
1136: - numeric and character formats are now tested;
1137: - -A flag is added. -A is used to give command line parameters to main
1138: routine. Example:

1247: - HELP function is rewritten to be more friendly (a la OpenVMS);
1248: - external wrapper (rplplot) is written to force usage of gnuplot provided
1249: by RPL/2 if it is built during build process. If this build does not exist,
1250: it tries to launch regular gnuplot;
1251: - gnuplot is added to source tree to avoid some trouble between preinstalled
1252: gnuplot and release used by RPL/2. This addition to source tree is

1631: fine...);
1632: - NOT is not correctly formatted in formateur.c:
1633: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1634: with a NOTZ function !
1635: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1638: - RPL/2 is tested with efence and valgrind;
1639: - configure.in script is modified;
1640: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1701: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1702: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1703: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1720: - SCLS is added;
1721: - DRWS now uses COLS to draw 2D graphics;
1722: - PPAR and SPAR are written. SPAR returns a list that contains the
1723: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1724: statistical variable, or "DISABLED" if its type is not one of the type of
1725: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1726: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1727: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1728: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1729: disabled. Arguments of EXTERNAL are case sensitive because the external
1730: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1731: of known external functions but add the new list to the last. { "all" }
1732: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1733: external names of the known functions;
1734: - mkrplso.in is modified.
1735: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1749: VISIT does not find a name in level 1;
1750: - configure.in script is modified to add a new test (--enable-debug
1751: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1752: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1753: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1754: 'MATRIX' { 2 2 3 } GETR;
1755: - LOGSCALE intrinsic is improved and now, it can be used as
1756: { "main" "auxiliary" X Y } LOGSCALE;
1757: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1758: same than AXES:
1759: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1760: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1761: { { -10 10 } "automatic" } SCALE.
1762: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1763: because it changes only the dimension of the screen. To have a logarithmic
1764: scale, you must use LOGSCALE intrinsic:
1765: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1766: screen on second scale;
1767: - { X X } autoscale and { Y Y } logscale are now invalid;
1768: - *D is added (depth multiplication, for 3D graphics);
1769: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1770: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1771: - a major bug is fixed in GETI instrinsic when it is used with a name
1772: that contains a matrix or a vector (bad upper bounds conditions in
1773: incrementation);
1774: - DISP intrinsic now uses the 33-th flag. When it is not set
1775: (default), a final carriage return is sent to the terminal;
1776: - AXES intrinsic only takes a list that can contains the keywork
1777: "main" or "auxiliary". Before this modification, this keyword was in
1778: the first stack level;
1779: - vim syntax file is upgraded;
1780: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1781: option;
1782: - LAST is now disabled in the main loop of INT intrinsic;
1783: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1784: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1785: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1786: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1787: in 0);
1788: - LAST is disabled in the main loop of DRAW intrinsic;
1789: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1790: evaluation of an equation, the system stack is returned corrupted to the
1791: sequencer;
1792: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1793: of a loop are not integer or real.
1794: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1797: add some tests in gestion_variables.c;
1798: - recherche_type() subroutine ad some other connex subroutines are improved.
1799: Now, some syntax errors about object are caught and do not perform sequencer
1800: hangup;
1801: - readline is upgraded (minor compilation bug with recent gcc);
1802: - Makefile.am's and configure.in scripts are improved.
1803: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1804: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1805: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1807: - recherche_type() is rewritten to be faster;
1808: - gsl is upgraded (release 1.3);
1809: - ncurses is upgraded and patched (release 5.3);
1810: - recherche_instruction_suivante() is fixed (string research with included
1811: '"') and rewritten to be faster;

1822: - a minor bug is fixed in evaluation subroutine;
1823: - vim syntax file is improved;
1824: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1825: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1826: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1827: is a quick and dirty workaround...);
1828: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1829: - rplconvert is improved.

1911: deleted too!;
1912: - configure script is improved (and it seems to be good ;-) );

1929: signal is an asynchonous "HALT" command;
1930: - SIGINT (CTRL+C) variables stack corruption is fixed;
1931: - IFERR seems to be fixed (in equation evaluation routine);

1940: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1941: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1942:
1943: Newton:[~/rpl/rpl] > time make install
1944: ...
1945: real 338m39.623s
1946: user 324m32.290s
