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

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

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

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

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

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

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

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

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

763: between process are done with pipes and these pipes are managed by a
764: specific asynchrone thread. If a script try to create more threads than
765: management thread can destroy, you can quickly achieve maximum number of

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

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

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

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

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

1080: before starting interrupt evaluation;
1081: - -f parameter is added when iconv is called;
1082: - as old file program was bugged, a new option is added to configure script.
1083: When configure is called with --disable-encoding-autodetection, make does not

1085: without this option !
1086: - new garbage collector (and more efficient) is written;
1087: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1088: not support real time signals, RPL/2 cannot use multitasking functions;
1089: - error returned by preprocessor are now catched by RPL/2;
1090: - -p option is added. With this option, all scripts are compiled before
1091: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run

1123: than 1E6;
1124: - numeric and character formats are now tested;
1125: - -A flag is added. -A is used to give command line parameters to main
1126: routine. Example:

1235: - HELP function is rewritten to be more friendly (a la OpenVMS);
1236: - external wrapper (rplplot) is written to force usage of gnuplot provided
1237: by RPL/2 if it is built during build process. If this build does not exist,
1238: it tries to launch regular gnuplot;
1239: - gnuplot is added to source tree to avoid some trouble between preinstalled
1240: gnuplot and release used by RPL/2. This addition to source tree is

1619: fine...);
1620: - NOT is not correctly formatted in formateur.c:
1621: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1622: with a NOTZ function !
1623: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1626: - RPL/2 is tested with efence and valgrind;
1627: - configure.in script is modified;
1628: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1689: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1690: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1691: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1708: - SCLS is added;
1709: - DRWS now uses COLS to draw 2D graphics;
1710: - PPAR and SPAR are written. SPAR returns a list that contains the
1711: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1712: statistical variable, or "DISABLED" if its type is not one of the type of
1713: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1714: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1715: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1716: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1717: disabled. Arguments of EXTERNAL are case sensitive because the external
1718: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1719: of known external functions but add the new list to the last. { "all" }
1720: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1721: external names of the known functions;
1722: - mkrplso.in is modified.
1723: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1724: - vim syntax file is upgraded;
1725: - a minor mistake is fixed in recherche_instruction_suivante();
1726: - some minor memory leaks are fixed in recherche_type() function. They only

1729: - INCR and DECR are written (with integer or variable argument);
1730: - CSWP and RSWP are added and tested;
1731: - a minor bug is fixed in analyse.c;

1734: - PUTC and PUTR new intrinsics are added.
1735: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1736: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1737: VISIT does not find a name in level 1;
1738: - configure.in script is modified to add a new test (--enable-debug
1739: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1740: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1741: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1742: 'MATRIX' { 2 2 3 } GETR;
1743: - LOGSCALE intrinsic is improved and now, it can be used as
1744: { "main" "auxiliary" X Y } LOGSCALE;
1745: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1746: same than AXES:
1747: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1748: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1749: { { -10 10 } "automatic" } SCALE.
1750: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1751: because it changes only the dimension of the screen. To have a logarithmic
1752: scale, you must use LOGSCALE intrinsic:
1753: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1754: screen on second scale;
1755: - { X X } autoscale and { Y Y } logscale are now invalid;
1756: - *D is added (depth multiplication, for 3D graphics);
1757: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1758: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1759: - a major bug is fixed in GETI instrinsic when it is used with a name
1760: that contains a matrix or a vector (bad upper bounds conditions in
1761: incrementation);
1762: - DISP intrinsic now uses the 33-th flag. When it is not set
1763: (default), a final carriage return is sent to the terminal;
1764: - AXES intrinsic only takes a list that can contains the keywork
1765: "main" or "auxiliary". Before this modification, this keyword was in
1766: the first stack level;
1767: - vim syntax file is upgraded;
1768: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1769: option;
1770: - LAST is now disabled in the main loop of INT intrinsic;
1771: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1772: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1773: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1774: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1775: in 0);
1776: - LAST is disabled in the main loop of DRAW intrinsic;
1777: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1778: evaluation of an equation, the system stack is returned corrupted to the
1779: sequencer;
1780: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1781: of a loop are not integer or real.
1782: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1783: - the compilation stage aborts with an error message when two definitions
1784: have the same name. To improve the compilation() subroutine, I have to
1785: add some tests in gestion_variables.c;
1786: - recherche_type() subroutine ad some other connex subroutines are improved.
1787: Now, some syntax errors about object are caught and do not perform sequencer
1788: hangup;
1789: - readline is upgraded (minor compilation bug with recent gcc);
1790: - Makefile.am's and configure.in scripts are improved.
1791: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1792: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1793: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1794: the boxwidth, 1 by default);
1795: - recherche_type() is rewritten to be faster;
1796: - gsl is upgraded (release 1.3);
1797: - ncurses is upgraded and patched (release 5.3);
1798: - recherche_instruction_suivante() is fixed (string research with included
1799: '"') and rewritten to be faster;

1810: - a minor bug is fixed in evaluation subroutine;
1811: - vim syntax file is improved;
1812: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1813: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1814: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1815: is a quick and dirty workaround...);
1816: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1817: - rplconvert is improved.

1834: Now, an expression such as 'A+' returns an error when it is analyzed;
1835: - VISIT intrinsic is added;
1836: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1837: normal mode.

1899: deleted too!;
1900: - configure script is improved (and it seems to be good ;-) );
1901: - An --disable-experimental flag is added to the configure script. Thus, even
1902: if you compile a beta release, you can compile a stable RPL/2;
1903: - new syntax and ftplugin written for vim 6.0.

1916: that the RPL/2 seqencer must stop and must give a prompt. This
1917: signal is an asynchonous "HALT" command;
1918: - SIGINT (CTRL+C) variables stack corruption is fixed;
1919: - IFERR seems to be fixed (in equation evaluation routine);
1920: - Memory leak is fixed (ADR object type);

1927: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1928: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1929: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1930:
1931: Newton:[~/rpl/rpl] > time make install
1932: ...
1933: real 338m39.623s
1934: user 324m32.290s
1935: sys 10m47.380s
1936: Newton:[~/rpl/rpl] >
1937:
1938: I don't know if you will compile this language on old worstations, but
1939: it is usable ;-) ;
1940: - SYSEVAL is improved. An external program can be called without any shell.
1941: Thus, even if the sticky bit is set, RPL/2 can not give a shell root when
1942: a SYSEVAL command crashes;
