382: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
383: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
384: "ALL" IMPLICIT when it runs in interactive mode;
385: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
386: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
387: to use SAVE to manipulate global variables;
388: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
389: subroutines;
390: - fix major memory access violation in evaluation subroutine. Only occurs
391: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
392: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
393: when X was a vector or a table.
394: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

422: - gnuplot is upgraded to 4.4.2 due to major bugs.
423: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
424: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
425: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
426: corruption. As internal memory management have been improved, a best fit
427: allocator like ptmalloc3 is not required anymore;
428: - gnuplot is upgraded to 4.4.1;
429: - deadlock is fixed in signal handlers: same mutex was used in standard
430: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
431: and signal handlers. A new signal handler specific mutex is added;
432: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
433: that has to be evaluated by ->NUM;
434: - rplfile build process is modify to be sure that rplfile is not modified
435: after rpl build stage (to be sure that rplfile checksum is not modified after

440: ABORT now works on eComStation;
441: - sqlite is upgraded to 3.7.2;
442: - bug is fixed in software interrupts. When both process have different PID,
443: parent process was not interrupted if it is not group master process. To fix
444: this bug, SIGINJECT signal is not sent by child process but by control thread
445: in parent process;
446: - minor bug is fixed in data injection (POKE) that does not work as expected
447: when child process is protected by NRPROC.
448: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
449: - --enable-sysv-sems is added to configure script to use SystemV semaphores
450: functions instead of POSIX functions. This function is disabled or forced on
451: systems that does not provide correct POSIX or SysV semaphores subsystem;
452: - a dirty but not quick patch is written to workaround broken siginfo
453: structures. This patch has been successfully tested. It uses a segment of
454: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
455: (Unix PID);
456: - some OpenBSD's hacks are added;
457: - broken siginfo->si_pid field is now checked by configure script;
458: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

470: postgresql libraries are statically linked in rpl executable;
471: - units Makefile is modified to avoid readline and ncurses usages;
472: - sqlite is upgraded to 3.7.0.1;
473: - units is upgraded to 1.88;

475: Level 0 and 1 variables adresses were swapped when a global variable masked
476: a name of RPL/2 routine;
477: - major bug is fixed in global variable creation subroutine. When a global
478: variable was created and when a local variable existed with the same name,
479: computed address of global variable was wrong;
480: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
481: is forced in front of all libraries.
482: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
483: - BACKTRACE intrinsic is added;
484: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
485: when this structure is included in IFERR/THEN/END structure and when an error is
486: caught;
487: - major bug is fixed in analyse() subroutine. When evaluation() returned error
488: in a compiled program, analyse() caught this error twice and randomly aborted
489: with a segmentation error;
490: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
491: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
492: signals;
493: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
494: matrix.
495: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

513: format in FCH (file descriptor) and SCK (socket descriptor);
514: - debug routines are improved;
515: - PROCID is added;
516: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
517: and to not use swap;
518: - major bug is fixed in sql support. SQL connections were closed in all chield
519: process;
520: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
521: discovered in Solaris thread safe allocators (libmalloc and libumem) that
522: are first fit class allocators. Solaris libmtmalloc works better and is
523: a best fit class allocator but its performance is poor than ptmalloc3
524: performance;
525: - major bug is fixed in ROW+ intrinsic (new row was not added where it
526: should);
527: - minor bugs are fixed in interruptions.c (semaphores values when error is
528: caught);
529: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
530: created by SPAWN;
531: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute

540: information about shared variable was not copied to new processus structure;
541: - some little memory leaks are fixed in evaluation(), recherche_type() and
542: sequenceur(). They only occured when syntax error were caught;
543: - IMPLICIT causes execution error instead system error;
544: - Hurd support is improved but currently broken because Hurd does not support
545: SIG_INFO. Work in progress;
546: - OpenBSD specific support is removed from sources;
547: - support for Mac OS X and Windows/Cygwin is added.
548: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

587: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
588: - in formatted file, string format returned a variable length string even if
589: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
590: a variable length string and 'CHARACTER*(n)' a fixed length string;
591: - keyed access files support is added. Currently, only formatted files are
592: supported;
593: - direct access files support is added. Currenlty, these files can only be used
594: in formatted mode;
595: - virtual variables are now writte in UTF-8 and all special characters
596: in string are escaped;
597: - all formatted files are now converted into UTF-8;
598: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
599: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
600: each execution (md5 and sha1 sums) to enhance security. If one of these tools
601: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
602: on a non recoverable system error;
603: - openssl and sqlite3 libraries are added;
604: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
605: variable indicates RPL/2 root directory. If it is not set, root path
606: is given by configure script (d_exec_path);
607: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

640: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
641: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
642: signals sent to main process were not caught because DAEMON did not replace
643: old pid by new one;
644: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
645: evaluation when an error is reported from a subroutine in another subroutine.
646: For example, error was not caught in following program when it is executed with
647: -p option :
648: TEST << iferr TEST2 then end >>
649: TEST2 << 0 inv >>
650: - major bug is fixed in variable management. Some local variables were
651: seen as global ones;
652: - major bug is fixed in rplcore. Rplcore entered in dead lock when
653: script file contains a multibyte character;
654: - IN intrinsic is added;
655: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
656: returned false ;

664: - major bug is fixed in -A command line option (NULL character is missing);
665: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
666: made by blocks (1024 bytes). When an incomplete multibyte sequence is
667: encountered at end of block, subroutine aborts with an execution error;
668: - major bug is fixed in OPEN (TCP/IPv4 sockets).
669: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
670: - DISP now locks stdout;
671: - rpliconv is added to replace standard iconv provided by operating system.
672: Indeed, conversion between different encodages requires transliteration
673: that is not offered by some iconv utility;
674: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
675: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

677: - fprintf is replaced by some functions that allow transliterations between
678: locales;
679: - '"' can now be used in strings ("\"");
680: - iconv is called with -c in preprocessor stage. It is done to write
681: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
682: - double free is fixed in liberation() (type SQL, only occurs when locale is
683: set);
684: - LOCALIZATION, UCASE and LCASE are added;

688: used in onLoading from shared library, USE was pushed on stack as algebraic
689: expression;
690: - libiconv is upgraded to 1.13.1;
691: - gnuplot is upgraded to 4.2.6;
692: - gsl is upgraded to 1.13.

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

710: or thread number;
711: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
712: was called before a pending interruption5 (SIGFSTOP), signal handler uses
713: a freed semaphore and corrupts heap;
714: - CLRERR is added to erase previous errors;
715: - ERRN and ERRM return exception message and number;
716: - major bug is fixed in interruptions.c. All signal are now bufferised
717: when semaphore_liste_threads is null to avoid deadlock. This bug only
718: occured when STOP was sent to a dying thread or process (when this thread or
719: process was running retrait_thread());
720: - matrix rank is computed before matrix inversion;
721: - file locks are added to stdin and stdout. stderr is not locked because
722: all messages written by signal handlers are sent to stderr;

797: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
798: process is killed;
799: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
800: know typeof() intrinsic function. This function is not standard but exists
801: under Sun Studio, gcc, and maybe some others compilers. If this function does

866: SQLQUERY. With all new programs, you can open a real connection to databases;
867: - NRPROC is added. This new intrinsic is used to catch error from child
868: process. Without NRPROC, any errors returned by child process cause
869: main process to abort;
870: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
871: starts a new process). There are no mutexes in RPL/2 because all spawned process
872: use specific context. Nevertheless, shared variables and associated mutexes
873: should be added;

1151: ends;
1152: - MEM does not report static variable sizes;
1153: - minor bug is fixed in HELP intrinsic. When the last instruction was not
1154: known, HELP function was pushed in operational stack. HELP did not work

1167: - HELP function is rewritten to be more friendly (a la OpenVMS);
1168: - external wrapper (rplplot) is written to force usage of gnuplot provided
1169: by RPL/2 if it is built during build process. If this build does not exist,
1170: it tries to launch regular gnuplot;
1171: - gnuplot is added to source tree to avoid some trouble between preinstalled
1172: gnuplot and release used by RPL/2. This addition to source tree is
1173: required by some incompatibility between gnuplot releases;

1179: not writable;
1180: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1181: error scrutation.

1223: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1224: versions of PROTECT and UNPROTECT that only deal with global variables
1225: (see RCL/SAVE);
1226: - variable management routines have been rewritten. The new ones are
1227: uncompatible with the old ones. Before these changes, a local variable
1228: was exported to a child subroutine, but cannot be modified into this
1229: child subroutine. Now, a local variable is accessible only in its subroutine;
1230: - SAVE intrinsic is added to manipulate global variables;

1548: (less parenthesis);
1549: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1550: on Debian distribution, but since cpp is in the default path, RPL/2 works
1551: fine...);
1552: - NOT is not correctly formatted in formateur.c:
1553: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1554: with a NOTZ function !
1555: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1556: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1557: if the main loop is in a program;
1558: - RPL/2 is tested with efence and valgrind;
1559: - configure.in script is modified;
1560: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1561: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1621: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1622: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1623: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1640: - SCLS is added;
1641: - DRWS now uses COLS to draw 2D graphics;
1642: - PPAR and SPAR are written. SPAR returns a list that contains the
1643: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1644: statistical variable, or "DISABLED" if its type is not one of the type of
1645: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1646: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1647: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1648: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1649: disabled. Arguments of EXTERNAL are case sensitive because the external
1650: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1651: of known external functions but add the new list to the last. { "all" }
1652: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1653: external names of the known functions;
1654: - mkrplso.in is modified.
1655: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1656: - vim syntax file is upgraded;
1657: - a minor mistake is fixed in recherche_instruction_suivante();
1658: - some minor memory leaks are fixed in recherche_type() function. They only

1667: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1668: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1669: VISIT does not find a name in level 1;
1670: - configure.in script is modified to add a new test (--enable-debug
1671: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1672: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1673: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1674: 'MATRIX' { 2 2 3 } GETR;
1675: - LOGSCALE intrinsic is improved and now, it can be used as
1676: { "main" "auxiliary" X Y } LOGSCALE;
1677: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1678: same than AXES:
1679: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1680: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1681: { { -10 10 } "automatic" } SCALE.
1682: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1683: because it changes only the dimension of the screen. To have a logarithmic
1684: scale, you must use LOGSCALE intrinsic:
1685: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1686: screen on second scale;
1687: - { X X } autoscale and { Y Y } logscale are now invalid;
1688: - *D is added (depth multiplication, for 3D graphics);
1689: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1690: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1691: - a major bug is fixed in GETI instrinsic when it is used with a name
1692: that contains a matrix or a vector (bad upper bounds conditions in
1693: incrementation);
1694: - DISP intrinsic now uses the 33-th flag. When it is not set
1695: (default), a final carriage return is sent to the terminal;
1696: - AXES intrinsic only takes a list that can contains the keywork
1697: "main" or "auxiliary". Before this modification, this keyword was in
1698: the first stack level;
1699: - vim syntax file is upgraded;
1700: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1701: option;
1702: - LAST is now disabled in the main loop of INT intrinsic;
1703: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1704: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1705: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1706: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1707: in 0);
1708: - LAST is disabled in the main loop of DRAW intrinsic;
1709: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1710: evaluation of an equation, the system stack is returned corrupted to the
1711: sequencer;
1712: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1713: of a loop are not integer or real.
1714: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1715: - the compilation stage aborts with an error message when two definitions

1722: - Makefile.am's and configure.in scripts are improved.
1723: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1724: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1725: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1726: the boxwidth, 1 by default);
1727: - recherche_type() is rewritten to be faster;
1728: - gsl is upgraded (release 1.3);
1729: - ncurses is upgraded and patched (release 5.3);

1745: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1746: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1747: is a quick and dirty workaround...);
1748: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1749: - rplconvert is improved.
