323: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
324: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
325: "ALL" IMPLICIT when it runs in interactive mode;
326: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
327: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
328: to use SAVE to manipulate global variables;
329: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
330: subroutines;
331: - fix major memory access violation in evaluation subroutine. Only occurs
332: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
333: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
334: when X was a vector or a table.

1.52 bertrand 364: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
365: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
366: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
367: corruption. As internal memory management have been improved, a best fit
368: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 369: - gnuplot is upgraded to 4.4.1;
370: - deadlock is fixed in signal handlers: same mutex was used in standard
371: subroutines (without protected sections by sigprocmask() or pthread_sigmask())

374: that has to be evaluated by ->NUM;
1.49 bertrand 375: - rplfile build process is modify to be sure that rplfile is not modified
376: after rpl build stage (to be sure that rplfile checksum is not modified after

381: ABORT now works on eComStation;
382: - sqlite is upgraded to 3.7.2;
383: - bug is fixed in software interrupts. When both process have different PID,
384: parent process was not interrupted if it is not group master process. To fix
385: this bug, SIGINJECT signal is not sent by child process but by control thread
386: in parent process;
1.46 bertrand 387: - minor bug is fixed in data injection (POKE) that does not work as expected
388: when child process is protected by NRPROC.

1.43 bertrand 390: - --enable-sysv-sems is added to configure script to use SystemV semaphores
391: functions instead of POSIX functions. This function is disabled or forced on
392: systems that does not provide correct POSIX or SysV semaphores subsystem;
393: - a dirty but not quick patch is written to workaround broken siginfo
394: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 395: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 396: (Unix PID);

416: Level 0 and 1 variables adresses were swapped when a global variable masked
417: a name of RPL/2 routine;
1.35 bertrand 418: - major bug is fixed in global variable creation subroutine. When a global
419: variable was created and when a local variable existed with the same name,
420: computed address of global variable was wrong;
421: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
422: is forced in front of all libraries.

424: - BACKTRACE intrinsic is added;
425: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
426: when this structure is included in IFERR/THEN/END structure and when an error is
427: caught;
428: - major bug is fixed in analyse() subroutine. When evaluation() returned error
429: in a compiled program, analyse() caught this error twice and randomly aborted
430: with a segmentation error;
431: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
432: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
433: signals;
434: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty

460: process;
461: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
462: discovered in Solaris thread safe allocators (libmalloc and libumem) that

467: should);
468: - minor bugs are fixed in interruptions.c (semaphores values when error is
469: caught);
470: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
471: created by SPAWN;
472: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
473: ATEXIT. If it receives SIGFABORT, it does not;

1.13 bertrand 528: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
529: - in formatted file, string format returned a variable length string even if
530: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 531: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 532: - keyed access files support is added. Currently, only formatted files are

543: on a non recoverable system error;
544: - openssl and sqlite3 libraries are added;
545: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
546: variable indicates RPL/2 root directory. If it is not set, root path
547: is given by configure script (d_exec_path);
1.11 bertrand 548: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

581: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
582: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
583: signals sent to main process were not caught because DAEMON did not replace
584: old pid by new one;
585: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
586: evaluation when an error is reported from a subroutine in another subroutine.
587: For example, error was not caught in following program when it is executed with

596: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
597: returned false ;
598: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
599: programs;
600: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
601: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

618: - fprintf is replaced by some functions that allow transliterations between
619: locales;
620: - '"' can now be used in strings ("\"");
621: - iconv is called with -c in preprocessor stage. It is done to write

635: - pipe() is overwritten by a macro to avoid a system error. Communication
636: between process are done with pipes and these pipes are managed by a
637: specific asynchrone thread. If a script try to create more threads than
638: management thread can destroy, you can quickly achieve maximum number of
639: opened files and pipe() shall return a system error. This macro tries to create
640: pipes. If pipe() function returns an error, macro waits and retries. If
641: number of retries is greater than a hardcoded value, macro returns an error;
642: - major bug (deadlock) is fixed in process and thread management. I hope
643: this bug shall be the last one;

649: - some bugfixes are added in process management;
650: - all process management is rewritten to avoid usage of defunct process
651: or thread number;
652: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
653: was called before a pending interruption5 (SIGFSTOP), signal handler uses
654: a freed semaphore and corrupts heap;
655: - CLRERR is added to erase previous errors;
656: - ERRN and ERRM return exception message and number;
657: - major bug is fixed in interruptions.c. All signal are now bufferised
658: when semaphore_liste_threads is null to avoid deadlock. This bug only
659: occured when STOP was sent to a dying thread or process (when this thread or
660: process was running retrait_thread());
661: - matrix rank is computed before matrix inversion;
662: - file locks are added to stdin and stdout. stderr is not locked because
663: all messages written by signal handlers are sent to stderr;

738: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
739: process is killed;
740: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
741: know typeof() intrinsic function. This function is not standard but exists

807: SQLQUERY. With all new programs, you can open a real connection to databases;
808: - NRPROC is added. This new intrinsic is used to catch error from child
809: process. Without NRPROC, any errors returned by child process cause
810: main process to abort;
811: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
812: starts a new process). There are no mutexes in RPL/2 because all spawned process

1082: an algebraic expression;
1083: - --enable-debug is modified. Now, return can be defined to print
1084: on stdout its position in source code (line and function);
1085: - minor bug is fixed in recherche_type(). Don't forget that space
1086: are not significant in algebraic expression:
1087: '12 3+ 12 X' is the same expression than '123+12X';
1088: - src/Makefile.am is modified to avoid double compilation process;
1089: - --enable-final-run-path is added to configure.in script;

1108: - HELP function is rewritten to be more friendly (a la OpenVMS);
1109: - external wrapper (rplplot) is written to force usage of gnuplot provided
1110: by RPL/2 if it is built during build process. If this build does not exist,
1111: it tries to launch regular gnuplot;
1112: - gnuplot is added to source tree to avoid some trouble between preinstalled
1113: gnuplot and release used by RPL/2. This addition to source tree is
1114: required by some incompatibility between gnuplot releases;

1120: not writable;
1121: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1122: error scrutation.

1167: - variable management routines have been rewritten. The new ones are
1168: uncompatible with the old ones. Before these changes, a local variable
1169: was exported to a child subroutine, but cannot be modified into this
1170: child subroutine. Now, a local variable is accessible only in its subroutine;
1171: - SAVE intrinsic is added to manipulate global variables;

1490: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1491: on Debian distribution, but since cpp is in the default path, RPL/2 works
1492: fine...);
1493: - NOT is not correctly formatted in formateur.c:
1494: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1495: with a NOTZ function !
1496: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1497: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1499: - RPL/2 is tested with efence and valgrind;
1500: - configure.in script is modified;
1501: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1502: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1562: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1563: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1564: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1581: - SCLS is added;
1582: - DRWS now uses COLS to draw 2D graphics;
1583: - PPAR and SPAR are written. SPAR returns a list that contains the
1584: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1585: statistical variable, or "DISABLED" if its type is not one of the type of
1586: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1587: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1588: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1589: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1590: disabled. Arguments of EXTERNAL are case sensitive because the external
1591: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1592: of known external functions but add the new list to the last. { "all" }
1593: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1594: external names of the known functions;
1595: - mkrplso.in is modified.
1596: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1597: - vim syntax file is upgraded;
1598: - a minor mistake is fixed in recherche_instruction_suivante();
1599: - some minor memory leaks are fixed in recherche_type() function. They only

1608: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1609: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1610: VISIT does not find a name in level 1;
1611: - configure.in script is modified to add a new test (--enable-debug
1612: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1613: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1614: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1615: 'MATRIX' { 2 2 3 } GETR;
1616: - LOGSCALE intrinsic is improved and now, it can be used as
1617: { "main" "auxiliary" X Y } LOGSCALE;
1618: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1619: same than AXES:
1620: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1621: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1622: { { -10 10 } "automatic" } SCALE.
1623: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1624: because it changes only the dimension of the screen. To have a logarithmic
1625: scale, you must use LOGSCALE intrinsic:
1626: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1627: screen on second scale;
1628: - { X X } autoscale and { Y Y } logscale are now invalid;
1629: - *D is added (depth multiplication, for 3D graphics);
1630: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1631: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1632: - a major bug is fixed in GETI instrinsic when it is used with a name
1633: that contains a matrix or a vector (bad upper bounds conditions in
1634: incrementation);
1635: - DISP intrinsic now uses the 33-th flag. When it is not set
1636: (default), a final carriage return is sent to the terminal;
1637: - AXES intrinsic only takes a list that can contains the keywork
1638: "main" or "auxiliary". Before this modification, this keyword was in
1639: the first stack level;
1640: - vim syntax file is upgraded;
1641: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1642: option;
1643: - LAST is now disabled in the main loop of INT intrinsic;
1644: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1645: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1646: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1647: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1648: in 0);
1649: - LAST is disabled in the main loop of DRAW intrinsic;
1650: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1651: evaluation of an equation, the system stack is returned corrupted to the
1652: sequencer;
1653: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1654: of a loop are not integer or real.
1655: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1656: - the compilation stage aborts with an error message when two definitions

1663: - Makefile.am's and configure.in scripts are improved.
1664: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1665: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1666: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1667: the boxwidth, 1 by default);
1668: - recherche_type() is rewritten to be faster;
1669: - gsl is upgraded (release 1.3);
1670: - ncurses is upgraded and patched (release 5.3);
1671: - recherche_instruction_suivante() is fixed (string research with included
1672: '"') and rewritten to be faster;

1686: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1687: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1688: is a quick and dirty workaround...);
1689: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1690: - rplconvert is improved.

1800: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1801: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1802: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1803:
1804: Newton:[~/rpl/rpl] > time make install
1805: ...
1806: real 338m39.623s
1807: user 324m32.290s
