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

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

438: ABORT now works on eComStation;
439: - sqlite is upgraded to 3.7.2;
440: - bug is fixed in software interrupts. When both process have different PID,
441: parent process was not interrupted if it is not group master process. To fix
442: this bug, SIGINJECT signal is not sent by child process but by control thread
443: in parent process;
444: - minor bug is fixed in data injection (POKE) that does not work as expected
445: when child process is protected by NRPROC.
446: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
447: - --enable-sysv-sems is added to configure script to use SystemV semaphores
448: functions instead of POSIX functions. This function is disabled or forced on
449: systems that does not provide correct POSIX or SysV semaphores subsystem;
450: - a dirty but not quick patch is written to workaround broken siginfo
451: structures. This patch has been successfully tested. It uses a segment of
452: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
453: (Unix PID);
454: - some OpenBSD's hacks are added;
455: - broken siginfo->si_pid field is now checked by configure script;

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

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

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

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

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

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

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

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

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

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

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

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

1149: ends;
1150: - MEM does not report static variable sizes;
1151: - minor bug is fixed in HELP intrinsic. When the last instruction was not
1152: known, HELP function was pushed in operational stack. HELP did not work

1165: - HELP function is rewritten to be more friendly (a la OpenVMS);
1166: - external wrapper (rplplot) is written to force usage of gnuplot provided
1167: by RPL/2 if it is built during build process. If this build does not exist,
1168: it tries to launch regular gnuplot;
1169: - gnuplot is added to source tree to avoid some trouble between preinstalled
1170: gnuplot and release used by RPL/2. This addition to source tree is
1171: required by some incompatibility between gnuplot releases;

1177: not writable;
1178: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1179: error scrutation.

1221: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1222: versions of PROTECT and UNPROTECT that only deal with global variables
1223: (see RCL/SAVE);
1224: - variable management routines have been rewritten. The new ones are
1225: uncompatible with the old ones. Before these changes, a local variable
1226: was exported to a child subroutine, but cannot be modified into this
1227: child subroutine. Now, a local variable is accessible only in its subroutine;
1228: - SAVE intrinsic is added to manipulate global variables;

1546: (less parenthesis);
1547: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1548: on Debian distribution, but since cpp is in the default path, RPL/2 works
1549: fine...);
1550: - NOT is not correctly formatted in formateur.c:
1551: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1552: with a NOTZ function !
1553: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1554: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1555: if the main loop is in a program;
1556: - RPL/2 is tested with efence and valgrind;
1557: - configure.in script is modified;
1558: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1559: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1619: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1620: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1621: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1638: - SCLS is added;
1639: - DRWS now uses COLS to draw 2D graphics;
1640: - PPAR and SPAR are written. SPAR returns a list that contains the
1641: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1642: statistical variable, or "DISABLED" if its type is not one of the type of
1643: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1644: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1645: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1646: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1647: disabled. Arguments of EXTERNAL are case sensitive because the external
1648: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1649: of known external functions but add the new list to the last. { "all" }
1650: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1651: external names of the known functions;
1652: - mkrplso.in is modified.
1653: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1654: - vim syntax file is upgraded;
1655: - a minor mistake is fixed in recherche_instruction_suivante();
1656: - some minor memory leaks are fixed in recherche_type() function. They only

1665: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1666: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1667: VISIT does not find a name in level 1;
1668: - configure.in script is modified to add a new test (--enable-debug
1669: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1670: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1671: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1672: 'MATRIX' { 2 2 3 } GETR;
1673: - LOGSCALE intrinsic is improved and now, it can be used as
1674: { "main" "auxiliary" X Y } LOGSCALE;
1675: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1676: same than AXES:
1677: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1678: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1679: { { -10 10 } "automatic" } SCALE.
1680: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1681: because it changes only the dimension of the screen. To have a logarithmic
1682: scale, you must use LOGSCALE intrinsic:
1683: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1684: screen on second scale;
1685: - { X X } autoscale and { Y Y } logscale are now invalid;
1686: - *D is added (depth multiplication, for 3D graphics);
1687: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1688: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1689: - a major bug is fixed in GETI instrinsic when it is used with a name
1690: that contains a matrix or a vector (bad upper bounds conditions in
1691: incrementation);
1692: - DISP intrinsic now uses the 33-th flag. When it is not set
1693: (default), a final carriage return is sent to the terminal;
1694: - AXES intrinsic only takes a list that can contains the keywork
1695: "main" or "auxiliary". Before this modification, this keyword was in
1696: the first stack level;
1697: - vim syntax file is upgraded;
1698: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1699: option;
1700: - LAST is now disabled in the main loop of INT intrinsic;
1701: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1702: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1703: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1704: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1705: in 0);
1706: - LAST is disabled in the main loop of DRAW intrinsic;
1707: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1708: evaluation of an equation, the system stack is returned corrupted to the
1709: sequencer;
1710: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1711: of a loop are not integer or real.
1712: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1720: - Makefile.am's and configure.in scripts are improved.
1721: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1722: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1723: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1743: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1744: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1745: is a quick and dirty workaround...);
1746: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1747: - rplconvert is improved.
