367: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
368: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
369: "ALL" IMPLICIT when it runs in interactive mode;
370: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
371: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
372: to use SAVE to manipulate global variables;
373: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
374: subroutines;
375: - fix major memory access violation in evaluation subroutine. Only occurs
376: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;

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

429: this bug, SIGINJECT signal is not sent by child process but by control thread
430: in parent process;
431: - minor bug is fixed in data injection (POKE) that does not work as expected
432: when child process is protected by NRPROC.
433: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
434: - --enable-sysv-sems is added to configure script to use SystemV semaphores
435: functions instead of POSIX functions. This function is disabled or forced on
436: systems that does not provide correct POSIX or SysV semaphores subsystem;
437: - a dirty but not quick patch is written to workaround broken siginfo
438: structures. This patch has been successfully tested. It uses a segment of
439: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
440: (Unix PID);
441: - some OpenBSD's hacks are added;
442: - broken siginfo->si_pid field is now checked by configure script;

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

468: - BACKTRACE intrinsic is added;
469: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
470: when this structure is included in IFERR/THEN/END structure and when an error is
471: caught;
472: - major bug is fixed in analyse() subroutine. When evaluation() returned error
473: in a compiled program, analyse() caught this error twice and randomly aborted
474: with a segmentation error;
475: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
476: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
477: signals;
478: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
479: matrix.
480: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

501: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
502: and to not use swap;
503: - major bug is fixed in sql support. SQL connections were closed in all chield
504: process;
505: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
506: discovered in Solaris thread safe allocators (libmalloc and libumem) that
507: are first fit class allocators. Solaris libmtmalloc works better and is
508: a best fit class allocator but its performance is poor than ptmalloc3
509: performance;
510: - major bug is fixed in ROW+ intrinsic (new row was not added where it
511: should);
512: - minor bugs are fixed in interruptions.c (semaphores values when error is

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

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

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

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

662: - fprintf is replaced by some functions that allow transliterations between
663: locales;
664: - '"' can now be used in strings ("\"");
665: - iconv is called with -c in preprocessor stage. It is done to write
666: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;

668: set);
669: - LOCALIZATION, UCASE and LCASE are added;

676: - gnuplot is upgraded to 4.2.6;
677: - gsl is upgraded to 1.13.

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

697: was called before a pending interruption5 (SIGFSTOP), signal handler uses
698: a freed semaphore and corrupts heap;
699: - CLRERR is added to erase previous errors;
700: - ERRN and ERRM return exception message and number;
701: - major bug is fixed in interruptions.c. All signal are now bufferised
702: when semaphore_liste_threads is null to avoid deadlock. This bug only
703: occured when STOP was sent to a dying thread or process (when this thread or
704: process was running retrait_thread());
705: - matrix rank is computed before matrix inversion;
706: - file locks are added to stdin and stdout. stderr is not locked because
707: all messages written by signal handlers are sent to stderr;

782: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
783: process is killed;
784: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
785: know typeof() intrinsic function. This function is not standard but exists
786: under Sun Studio, gcc, and maybe some others compilers. If this function does
787: not exist on your compiler, you can change its definition by old one in
788: src/rpl.h;

829: static variable that is shared by multiple threads;
830: - '->' intrinsic is improved. All object copies have been avoided;
831: - -n flag is added to catch HUP signal. stderr and stdout are redirected
832: to a file, stdin is redirected to /dev/null when control process is killed;

850: that all programs that worked with old SQL intrinsic can now work with
851: SQLQUERY. With all new programs, you can open a real connection to databases;
852: - NRPROC is added. This new intrinsic is used to catch error from child
853: process. Without NRPROC, any errors returned by child process cause
854: main process to abort;
855: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
856: starts a new process). There are no mutexes in RPL/2 because all spawned process
857: use specific context. Nevertheless, shared variables and associated mutexes
858: should be added;

1164: not writable;
1165: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1166: error scrutation.

1182: it is possible to execute:
1183:
1184: #!/usr/local/bin/rpl -sc
1185:
1186: TEST
1187: <<
1188: 1 1000 start VAR_S VAR_S2 next

1211: - variable management routines have been rewritten. The new ones are
1212: uncompatible with the old ones. Before these changes, a local variable
1213: was exported to a child subroutine, but cannot be modified into this
1214: child subroutine. Now, a local variable is accessible only in its subroutine;
1215: - SAVE intrinsic is added to manipulate global variables;

1532: - algebraic expressions are now more readable when they are displayed
1533: (less parenthesis);
1534: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1535: on Debian distribution, but since cpp is in the default path, RPL/2 works
1536: fine...);
1537: - NOT is not correctly formatted in formateur.c:
1538: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1539: with a NOTZ function !
1540: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1541: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1542: if the main loop is in a program;
1543: - RPL/2 is tested with efence and valgrind;
1544: - configure.in script is modified;
1545: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1546: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1547: another gcc bug...
1548: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)
1549: - EXIT is fixed. Now, it is possible to use EXIT in an expression when the
1550: main loop is in a program;

1581: 2: integer (number of column to be inserted)
1582: 1: column matrix to be inserted;
1583: - major bug was discovered in interface_gnuplot(). It only occurs when

1592: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1593: - SLICESCALE intrinsic is added. Its syntax is
1594: { "automatic" nb_of_levels }
1595: { "discrete" l1 l2 l3 ... }
1596: { "incremental" start incr }
1597: { "incremental" start incr end }
1598: { "automatic" } (default);

1600: - flag 52 is used to automatically update graphics;
1601: - man pages are updated;
1602: - evaluation() is modified to perform evaluation of expressions that contain
1603: '=';
1604: - a minor bug is fixed in AXES intrinsic;

1606: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1607: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1608: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1609: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1625: - SCLS is added;
1626: - DRWS now uses COLS to draw 2D graphics;
1627: - PPAR and SPAR are written. SPAR returns a list that contains the
1628: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1629: statistical variable, or "DISABLED" if its type is not one of the type of
1630: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1631: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1632: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1633: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1634: disabled. Arguments of EXTERNAL are case sensitive because the external
1635: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1636: of known external functions but add the new list to the last. { "all" }
1637: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1638: external names of the known functions;
1639: - mkrplso.in is modified.
1640: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1641: - vim syntax file is upgraded;
1642: - a minor mistake is fixed in recherche_instruction_suivante();
1643: - some minor memory leaks are fixed in recherche_type() function. They only
1644: occurs when a syntax error is detected;

1646: - INCR and DECR are written (with integer or variable argument);
1647: - CSWP and RSWP are added and tested;
1648: - a minor bug is fixed in analyse.c;
1649: - DEBIAN/control is added to build debian package;
1650: - SCALE is fixed and improved ("automatic" keyword);
1651: - PUTC and PUTR new intrinsics are added.
1652: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1653: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1654: VISIT does not find a name in level 1;
1655: - configure.in script is modified to add a new test (--enable-debug
1656: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1657: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1658: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1659: 'MATRIX' { 2 2 3 } GETR;
1660: - LOGSCALE intrinsic is improved and now, it can be used as
1661: { "main" "auxiliary" X Y } LOGSCALE;
1662: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1663: same than AXES:
1664: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1665: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1666: { { -10 10 } "automatic" } SCALE.
1667: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1668: because it changes only the dimension of the screen. To have a logarithmic
1669: scale, you must use LOGSCALE intrinsic:
1670: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1671: screen on second scale;
1672: - { X X } autoscale and { Y Y } logscale are now invalid;
1673: - *D is added (depth multiplication, for 3D graphics);
1674: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1675: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1676: - a major bug is fixed in GETI instrinsic when it is used with a name
1677: that contains a matrix or a vector (bad upper bounds conditions in
1678: incrementation);
1679: - DISP intrinsic now uses the 33-th flag. When it is not set
1680: (default), a final carriage return is sent to the terminal;
1681: - AXES intrinsic only takes a list that can contains the keywork
1682: "main" or "auxiliary". Before this modification, this keyword was in
1683: the first stack level;
1684: - vim syntax file is upgraded;
1685: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1686: option;
1687: - LAST is now disabled in the main loop of INT intrinsic;
1688: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1689: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1690: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1691: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1692: in 0);
1693: - LAST is disabled in the main loop of DRAW intrinsic;
1694: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1695: evaluation of an equation, the system stack is returned corrupted to the
1696: sequencer;
1697: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1698: of a loop are not integer or real.
1699: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1700: - the compilation stage aborts with an error message when two definitions
1701: have the same name. To improve the compilation() subroutine, I have to
1702: add some tests in gestion_variables.c;
1703: - recherche_type() subroutine ad some other connex subroutines are improved.
1704: Now, some syntax errors about object are caught and do not perform sequencer
1705: hangup;

1707: - Makefile.am's and configure.in scripts are improved.
1708: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1709: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1710: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1711: the boxwidth, 1 by default);
1712: - recherche_type() is rewritten to be faster;
1713: - gsl is upgraded (release 1.3);
1714: - ncurses is upgraded and patched (release 5.3);
1715: - recherche_instruction_suivante() is fixed (string research with included
1716: '"') and rewritten to be faster;

1727: - a minor bug is fixed in evaluation subroutine;
1728: - vim syntax file is improved;
1729: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1730: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1731: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1732: is a quick and dirty workaround...);
1733: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1734: - rplconvert is improved.
1735: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1751: Now, an expression such as 'A+' returns an error when it is analyzed;
1752: - VISIT intrinsic is added;
1753: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1754: normal mode.
