364: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
365: "ALL" IMPLICIT when it runs in interactive mode;
366: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
367: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
368: to use SAVE to manipulate global variables;
369: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
370: subroutines;
371: - fix major memory access violation in evaluation subroutine. Only occurs
372: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
373: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
374: when X was a vector or a table.

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

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

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

464: - BACKTRACE intrinsic is added;
465: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
466: when this structure is included in IFERR/THEN/END structure and when an error is
467: caught;
468: - major bug is fixed in analyse() subroutine. When evaluation() returned error
469: in a compiled program, analyse() caught this error twice and randomly aborted
470: with a segmentation error;
471: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
472: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
473: signals;
474: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
475: matrix.

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

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

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

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

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

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

664: set);
665: - LOCALIZATION, UCASE and LCASE are added;

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

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

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

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

825: static variable that is shared by multiple threads;
826: - '->' intrinsic is improved. All object copies have been avoided;
827: - -n flag is added to catch HUP signal. stderr and stdout are redirected
828: to a file, stdin is redirected to /dev/null when control process is killed;
829: - a mutex is added to each object (before this modification,

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

1182: TEST
1183: <<
1184: 1 1000 start VAR_S VAR_S2 next

1207: - variable management routines have been rewritten. The new ones are
1208: uncompatible with the old ones. Before these changes, a local variable
1209: was exported to a child subroutine, but cannot be modified into this
1210: child subroutine. Now, a local variable is accessible only in its subroutine;
1211: - SAVE intrinsic is added to manipulate global variables;

1529: (less parenthesis);
1530: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1531: on Debian distribution, but since cpp is in the default path, RPL/2 works
1532: fine...);
1533: - NOT is not correctly formatted in formateur.c:
1534: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1535: with a NOTZ function !
1536: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1537: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1538: if the main loop is in a program;
1539: - RPL/2 is tested with efence and valgrind;
1540: - configure.in script is modified;
1541: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1542: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1543: another gcc bug...
1544: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)
1545: - EXIT is fixed. Now, it is possible to use EXIT in an expression when the
1546: main loop is in a program;

1577: 2: integer (number of column to be inserted)
1578: 1: column matrix to be inserted;
1579: - major bug was discovered in interface_gnuplot(). It only occurs when

1588: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1589: - SLICESCALE intrinsic is added. Its syntax is
1590: { "automatic" nb_of_levels }
1591: { "discrete" l1 l2 l3 ... }
1592: { "incremental" start incr }
1593: { "incremental" start incr end }
1594: { "automatic" } (default);

1602: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1603: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1604: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1621: - SCLS is added;
1622: - DRWS now uses COLS to draw 2D graphics;
1623: - PPAR and SPAR are written. SPAR returns a list that contains the
1624: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1625: statistical variable, or "DISABLED" if its type is not one of the type of
1626: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1627: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1628: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1629: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1630: disabled. Arguments of EXTERNAL are case sensitive because the external
1631: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1632: of known external functions but add the new list to the last. { "all" }
1633: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1634: external names of the known functions;
1635: - mkrplso.in is modified.
1636: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1637: - vim syntax file is upgraded;
1638: - a minor mistake is fixed in recherche_instruction_suivante();
1639: - some minor memory leaks are fixed in recherche_type() function. They only

1642: - INCR and DECR are written (with integer or variable argument);
1643: - CSWP and RSWP are added and tested;
1644: - a minor bug is fixed in analyse.c;
1645: - DEBIAN/control is added to build debian package;

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

1703: - Makefile.am's and configure.in scripts are improved.
1704: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1705: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1706: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1707: the boxwidth, 1 by default);
1708: - recherche_type() is rewritten to be faster;
1709: - gsl is upgraded (release 1.3);
1710: - ncurses is upgraded and patched (release 5.3);
1711: - recherche_instruction_suivante() is fixed (string research with included
1712: '"') and rewritten to be faster;
1713: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1714: segfault.
1715: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1723: - a minor bug is fixed in evaluation subroutine;
1724: - vim syntax file is improved;
1725: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1726: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1727: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1728: is a quick and dirty workaround...);
1729: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1730: - rplconvert is improved.
1731: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1747: Now, an expression such as 'A+' returns an error when it is analyzed;
1748: - VISIT intrinsic is added;
1749: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1750: normal mode.

1838: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1839: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1840: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1841: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1842: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1843:
1844: Newton:[~/rpl/rpl] > time make install
1845: ...
1846: real 338m39.623s
1847: user 324m32.290s
1848: sys 10m47.380s
1849: Newton:[~/rpl/rpl] >
1850:
