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

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

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

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

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

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

616: SIG_INFO. Work in progress;
617: - OpenBSD specific support is removed from sources;
618: - support for Mac OS X and Windows/Cygwin is added.

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

713: signals sent to main process were not caught because DAEMON did not replace
714: old pid by new one;
715: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
716: evaluation when an error is reported from a subroutine in another subroutine.

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

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

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

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

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

1033: workaround for this major bug. Nevertheless, all others capabilities seems to
1034: work fine;
1035: - '->' is modified to return error when program tries to initialiaze two

1083: before starting interrupt evaluation;
1084: - -f parameter is added when iconv is called;
1085: - as old file program was bugged, a new option is added to configure script.
1086: When configure is called with --disable-encoding-autodetection, make does not

1126: than 1E6;
1127: - numeric and character formats are now tested;
1128: - -A flag is added. -A is used to give command line parameters to main
1129: routine. Example:

1215: - minor bug is fixed in recherche_type(). Don't forget that space
1216: are not significant in algebraic expression:
1217: '12 3+ 12 X' is the same expression than '123+12X';
1218: - src/Makefile.am is modified to avoid double compilation process;
1219: - --enable-final-run-path is added to configure.in script;

1238: - HELP function is rewritten to be more friendly (a la OpenVMS);
1239: - external wrapper (rplplot) is written to force usage of gnuplot provided
1240: by RPL/2 if it is built during build process. If this build does not exist,
1241: it tries to launch regular gnuplot;
1242: - gnuplot is added to source tree to avoid some trouble between preinstalled
1243: gnuplot and release used by RPL/2. This addition to source tree is

1294: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1295: versions of PROTECT and UNPROTECT that only deal with global variables
1296: (see RCL/SAVE);
1297: - variable management routines have been rewritten. The new ones are
1298: uncompatible with the old ones. Before these changes, a local variable
1299: was exported to a child subroutine, but cannot be modified into this
1300: child subroutine. Now, a local variable is accessible only in its subroutine;

1622: fine...);
1623: - NOT is not correctly formatted in formateur.c:
1624: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1625: with a NOTZ function !
1626: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1629: - RPL/2 is tested with efence and valgrind;
1630: - configure.in script is modified;
1631: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1692: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1693: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1694: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1711: - SCLS is added;
1712: - DRWS now uses COLS to draw 2D graphics;
1713: - PPAR and SPAR are written. SPAR returns a list that contains the
1714: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1715: statistical variable, or "DISABLED" if its type is not one of the type of
1716: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1717: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1718: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1719: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1720: disabled. Arguments of EXTERNAL are case sensitive because the external
1721: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1722: of known external functions but add the new list to the last. { "all" }
1723: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1724: external names of the known functions;
1725: - mkrplso.in is modified.
1726: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1727: - vim syntax file is upgraded;
1728: - a minor mistake is fixed in recherche_instruction_suivante();
1729: - some minor memory leaks are fixed in recherche_type() function. They only

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

1813: - a minor bug is fixed in evaluation subroutine;
1814: - vim syntax file is improved;
1815: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1816: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1817: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1818: is a quick and dirty workaround...);
1819: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1820: - rplconvert is improved.

1902: deleted too!;
1903: - configure script is improved (and it seems to be good ;-) );

1919: that the RPL/2 seqencer must stop and must give a prompt. This
1920: signal is an asynchonous "HALT" command;
1921: - SIGINT (CTRL+C) variables stack corruption is fixed;
1922: - IFERR seems to be fixed (in equation evaluation routine);
1923: - Memory leak is fixed (ADR object type);

1930: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1931: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1932: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1933:
1934: Newton:[~/rpl/rpl] > time make install
1935: ...
1936: real 338m39.623s
1937: user 324m32.290s
1938: sys 10m47.380s
1939: Newton:[~/rpl/rpl] >
1940:
1941: I don't know if you will compile this language on old worstations, but
1942: it is usable ;-) ;
1943: - SYSEVAL is improved. An external program can be called without any shell.
