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

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

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

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

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

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

614: sequenceur(). They only occured when syntax error were caught;
615: - IMPLICIT causes execution error instead system error;
616: - Hurd support is improved but currently broken because Hurd does not support
617: SIG_INFO. Work in progress;
618: - OpenBSD specific support is removed from sources;
619: - support for Mac OS X and Windows/Cygwin is added.

674: on a non recoverable system error;
675: - openssl and sqlite3 libraries are added;
676: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

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

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

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

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

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

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

1084: before starting interrupt evaluation;
1085: - -f parameter is added when iconv is called;
1086: - as old file program was bugged, a new option is added to configure script.
1087: When configure is called with --disable-encoding-autodetection, make does not

1127: than 1E6;
1128: - numeric and character formats are now tested;
1129: - -A flag is added. -A is used to give command line parameters to main
1130: routine. Example:

1216: - minor bug is fixed in recherche_type(). Don't forget that space
1217: are not significant in algebraic expression:
1218: '12 3+ 12 X' is the same expression than '123+12X';
1219: - src/Makefile.am is modified to avoid double compilation process;
1220: - --enable-final-run-path is added to configure.in script;

1239: - HELP function is rewritten to be more friendly (a la OpenVMS);
1240: - external wrapper (rplplot) is written to force usage of gnuplot provided
1241: by RPL/2 if it is built during build process. If this build does not exist,
1242: it tries to launch regular gnuplot;
1243: - gnuplot is added to source tree to avoid some trouble between preinstalled
1244: gnuplot and release used by RPL/2. This addition to source tree is

1298: - variable management routines have been rewritten. The new ones are
1299: uncompatible with the old ones. Before these changes, a local variable
1300: was exported to a child subroutine, but cannot be modified into this
1301: child subroutine. Now, a local variable is accessible only in its subroutine;

1623: fine...);
1624: - NOT is not correctly formatted in formateur.c:
1625: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1626: with a NOTZ function !
1627: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1630: - RPL/2 is tested with efence and valgrind;
1631: - configure.in script is modified;
1632: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1693: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1694: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1695: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1712: - SCLS is added;
1713: - DRWS now uses COLS to draw 2D graphics;
1714: - PPAR and SPAR are written. SPAR returns a list that contains the
1715: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1716: statistical variable, or "DISABLED" if its type is not one of the type of
1717: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1718: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1719: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1720: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1721: disabled. Arguments of EXTERNAL are case sensitive because the external
1722: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1723: of known external functions but add the new list to the last. { "all" }
1724: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1725: external names of the known functions;
1726: - mkrplso.in is modified.
1727: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1728: - vim syntax file is upgraded;
1729: - a minor mistake is fixed in recherche_instruction_suivante();
1730: - some minor memory leaks are fixed in recherche_type() function. They only

1739: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1740: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1741: VISIT does not find a name in level 1;
1742: - configure.in script is modified to add a new test (--enable-debug
1743: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1744: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1745: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1746: 'MATRIX' { 2 2 3 } GETR;
1747: - LOGSCALE intrinsic is improved and now, it can be used as
1748: { "main" "auxiliary" X Y } LOGSCALE;
1749: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1750: same than AXES:
1751: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1752: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1753: { { -10 10 } "automatic" } SCALE.
1754: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1755: because it changes only the dimension of the screen. To have a logarithmic
1756: scale, you must use LOGSCALE intrinsic:
1757: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1758: screen on second scale;
1759: - { X X } autoscale and { Y Y } logscale are now invalid;
1760: - *D is added (depth multiplication, for 3D graphics);
1761: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1762: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1763: - a major bug is fixed in GETI instrinsic when it is used with a name
1764: that contains a matrix or a vector (bad upper bounds conditions in
1765: incrementation);
1766: - DISP intrinsic now uses the 33-th flag. When it is not set
1767: (default), a final carriage return is sent to the terminal;
1768: - AXES intrinsic only takes a list that can contains the keywork
1769: "main" or "auxiliary". Before this modification, this keyword was in
1770: the first stack level;
1771: - vim syntax file is upgraded;
1772: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1773: option;
1774: - LAST is now disabled in the main loop of INT intrinsic;
1775: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1776: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1777: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1778: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1779: in 0);
1780: - LAST is disabled in the main loop of DRAW intrinsic;
1781: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1782: evaluation of an equation, the system stack is returned corrupted to the
1783: sequencer;
1784: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1785: of a loop are not integer or real.
1786: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1787: - the compilation stage aborts with an error message when two definitions
1788: have the same name. To improve the compilation() subroutine, I have to
1789: add some tests in gestion_variables.c;
1790: - recherche_type() subroutine ad some other connex subroutines are improved.
1791: Now, some syntax errors about object are caught and do not perform sequencer
1792: hangup;
1793: - readline is upgraded (minor compilation bug with recent gcc);
1794: - Makefile.am's and configure.in scripts are improved.
1795: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1796: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1797: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1798: the boxwidth, 1 by default);
1799: - recherche_type() is rewritten to be faster;
1800: - gsl is upgraded (release 1.3);
1801: - ncurses is upgraded and patched (release 5.3);
1802: - recherche_instruction_suivante() is fixed (string research with included
1803: '"') and rewritten to be faster;

1814: - a minor bug is fixed in evaluation subroutine;
1815: - vim syntax file is improved;
1816: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1817: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1818: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1819: is a quick and dirty workaround...);
1820: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1821: - rplconvert is improved.

1903: deleted too!;
1904: - configure script is improved (and it seems to be good ;-) );

1920: that the RPL/2 seqencer must stop and must give a prompt. This
1921: signal is an asynchonous "HALT" command;
1922: - SIGINT (CTRL+C) variables stack corruption is fixed;
1923: - IFERR seems to be fixed (in equation evaluation routine);
1924: - Memory leak is fixed (ADR object type);

1931: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1932: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1933: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1934:
1935: Newton:[~/rpl/rpl] > time make install
1936: ...
1937: real 338m39.623s
1938: user 324m32.290s
1939: sys 10m47.380s
1940: Newton:[~/rpl/rpl] >
1941:
1942: I don't know if you will compile this language on old worstations, but
1943: it is usable ;-) ;
1944: - SYSEVAL is improved. An external program can be called without any shell.
