392: - gnuplot is upgraded to 4.4.2 due to major bugs.
393: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
394: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
395: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
396: corruption. As internal memory management have been improved, a best fit
397: allocator like ptmalloc3 is not required anymore;
398: - gnuplot is upgraded to 4.4.1;
399: - deadlock is fixed in signal handlers: same mutex was used in standard
400: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
401: and signal handlers. A new signal handler specific mutex is added;
402: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
403: that has to be evaluated by ->NUM;
404: - rplfile build process is modify to be sure that rplfile is not modified
405: after rpl build stage (to be sure that rplfile checksum is not modified after
406: rpl compilation);

410: ABORT now works on eComStation;
411: - sqlite is upgraded to 3.7.2;
412: - bug is fixed in software interrupts. When both process have different PID,
413: parent process was not interrupted if it is not group master process. To fix
414: this bug, SIGINJECT signal is not sent by child process but by control thread
415: in parent process;
416: - minor bug is fixed in data injection (POKE) that does not work as expected
417: when child process is protected by NRPROC.
418: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
419: - --enable-sysv-sems is added to configure script to use SystemV semaphores
420: functions instead of POSIX functions. This function is disabled or forced on
421: systems that does not provide correct POSIX or SysV semaphores subsystem;
422: - a dirty but not quick patch is written to workaround broken siginfo
423: structures. This patch has been successfully tested. It uses a segment of
424: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
425: (Unix PID);
426: - some OpenBSD's hacks are added;
427: - broken siginfo->si_pid field is now checked by configure script;
428: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

445: Level 0 and 1 variables adresses were swapped when a global variable masked
446: a name of RPL/2 routine;
447: - major bug is fixed in global variable creation subroutine. When a global
448: variable was created and when a local variable existed with the same name,
449: computed address of global variable was wrong;
450: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
451: is forced in front of all libraries.
452: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
453: - BACKTRACE intrinsic is added;
454: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
455: when this structure is included in IFERR/THEN/END structure and when an error is
456: caught;
457: - major bug is fixed in analyse() subroutine. When evaluation() returned error
458: in a compiled program, analyse() caught this error twice and randomly aborted
459: with a segmentation error;
460: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
461: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
462: signals;
463: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
464: matrix.
465: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

483: format in FCH (file descriptor) and SCK (socket descriptor);
484: - debug routines are improved;
485: - PROCID is added;
486: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
487: and to not use swap;
488: - major bug is fixed in sql support. SQL connections were closed in all chield
489: process;
490: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
491: discovered in Solaris thread safe allocators (libmalloc and libumem) that
492: are first fit class allocators. Solaris libmtmalloc works better and is
493: a best fit class allocator but its performance is poor than ptmalloc3
494: performance;
495: - major bug is fixed in ROW+ intrinsic (new row was not added where it
496: should);
497: - minor bugs are fixed in interruptions.c (semaphores values when error is
498: caught);
499: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
500: created by SPAWN;
501: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
502: ATEXIT. If it receives SIGFABORT, it does not;
503: - ONEXIT is renamed in ATEXIT;
504: - ONEXIT new intrinsic is added.

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

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

610: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
611: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
612: signals sent to main process were not caught because DAEMON did not replace
613: old pid by new one;
614: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
615: evaluation when an error is reported from a subroutine in another subroutine.
616: For example, error was not caught in following program when it is executed with
617: -p option :
618: TEST << iferr TEST2 then end >>
619: TEST2 << 0 inv >>
620: - major bug is fixed in variable management. Some local variables were
621: seen as global ones;
622: - major bug is fixed in rplcore. Rplcore entered in dead lock when
623: script file contains a multibyte character;
624: - IN intrinsic is added;
625: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
626: returned false ;
627: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
628: programs;
629: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
630: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
631: strings were never closed;
632: - some bugs have been fixed in file management;

634: - major bug is fixed in -A command line option (NULL character is missing);
635: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
636: made by blocks (1024 bytes). When an incomplete multibyte sequence is
637: encountered at end of block, subroutine aborts with an execution error;
638: - major bug is fixed in OPEN (TCP/IPv4 sockets).
639: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
640: - DISP now locks stdout;
641: - rpliconv is added to replace standard iconv provided by operating system.
642: Indeed, conversion between different encodages requires transliteration
643: that is not offered by some iconv utility;
644: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
645: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
646: not be found), SYSEVAL enters in a dead lock;
647: - fprintf is replaced by some functions that allow transliterations between
648: locales;
649: - '"' can now be used in strings ("\"");
650: - iconv is called with -c in preprocessor stage. It is done to write
651: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
652: - double free is fixed in liberation() (type SQL, only occurs when locale is
653: set);
654: - LOCALIZATION, UCASE and LCASE are added;

658: used in onLoading from shared library, USE was pushed on stack as algebraic
659: expression;
660: - libiconv is upgraded to 1.13.1;
661: - gnuplot is upgraded to 4.2.6;
662: - gsl is upgraded to 1.13.

664: - pipe() is overwritten by a macro to avoid a system error. Communication
665: between process are done with pipes and these pipes are managed by a
666: specific asynchrone thread. If a script try to create more threads than
667: management thread can destroy, you can quickly achieve maximum number of
668: opened files and pipe() shall return a system error. This macro tries to create
669: pipes. If pipe() function returns an error, macro waits and retries. If
670: number of retries is greater than a hardcoded value, macro returns an error;
671: - major bug (deadlock) is fixed in process and thread management. I hope
672: this bug shall be the last one;
673: - major bug is fixed in DET intrinsic (determinant was computed without LU

679: - all process management is rewritten to avoid usage of defunct process
680: or thread number;
681: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
682: was called before a pending interruption5 (SIGFSTOP), signal handler uses
683: a freed semaphore and corrupts heap;
684: - CLRERR is added to erase previous errors;
685: - ERRN and ERRM return exception message and number;
686: - major bug is fixed in interruptions.c. All signal are now bufferised
687: when semaphore_liste_threads is null to avoid deadlock. This bug only
688: occured when STOP was sent to a dying thread or process (when this thread or
689: process was running retrait_thread());
690: - matrix rank is computed before matrix inversion;
691: - file locks are added to stdin and stdout. stderr is not locked because
692: all messages written by signal handlers are sent to stderr;
693: - configure.in script is modified to test gcc version and avoid a bug in

767: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
768: process is killed;
769: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
770: know typeof() intrinsic function. This function is not standard but exists
771: under Sun Studio, gcc, and maybe some others compilers. If this function does
772: not exist on your compiler, you can change its definition by old one in
773: src/rpl.h;
774: - fflush() can now be interrupted by signal (SunOS);
775: - fflush(NULL) is called before all fork() occurrences;

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

814: static variable that is shared by multiple threads;
815: - '->' intrinsic is improved. All object copies have been avoided;
816: - -n flag is added to catch HUP signal. stderr and stdout are redirected
817: to a file, stdin is redirected to /dev/null when control process is killed;
818: - a mutex is added to each object (before this modification,
819: RPL/2 used a global mutex and performances in multithreaded programs were very

835: that all programs that worked with old SQL intrinsic can now work with
836: SQLQUERY. With all new programs, you can open a real connection to databases;
837: - NRPROC is added. This new intrinsic is used to catch error from child
838: process. Without NRPROC, any errors returned by child process cause
839: main process to abort;
840: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
841: starts a new process). There are no mutexes in RPL/2 because all spawned process
842: use specific context. Nevertheless, shared variables and associated mutexes
843: should be added;

1138: - external wrapper (rplplot) is written to force usage of gnuplot provided
1139: by RPL/2 if it is built during build process. If this build does not exist,
1140: it tries to launch regular gnuplot;
1141: - gnuplot is added to source tree to avoid some trouble between preinstalled
1142: gnuplot and release used by RPL/2. This addition to source tree is
1143: required by some incompatibility between gnuplot releases;

1519: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1520: on Debian distribution, but since cpp is in the default path, RPL/2 works
1521: fine...);
1522: - NOT is not correctly formatted in formateur.c:
1523: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1524: with a NOTZ function !
1525: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1526: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1527: if the main loop is in a program;
1528: - RPL/2 is tested with efence and valgrind;
1529: - configure.in script is modified;
1530: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1531: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1532: another gcc bug...
1533: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)
1534: - EXIT is fixed. Now, it is possible to use EXIT in an expression when the
1535: main loop is in a program;

1538: - a minor bug in vim syntax file is fixed (CYCLE and EXIT intrinsics);
1539: - a minor bug is discovered in analyse_algebrique(). Now, expression
1540: such as 'A+Z AND 2' or '(A+Z) AND 2' are correctly parsed.

1560: 1: x;
1561: - ->Q intrinsic is added;
1562: - major bug is fixed in C->R intrinsic;
1563: - ROW+ and ROW- are added and tested;
1564: - COL+ and COL- are added and tested. Syntax:
1565: 3: matrix
1566: 2: integer (number of column to be inserted)
1567: 1: column matrix to be inserted;
1568: - major bug was discovered in interface_gnuplot(). It only occurs when

1577: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1578: - SLICESCALE intrinsic is added. Its syntax is
1579: { "automatic" nb_of_levels }
1580: { "discrete" l1 l2 l3 ... }
1581: { "incremental" start incr }
1582: { "incremental" start incr end }
1583: { "automatic" } (default);

1585: - flag 52 is used to automatically update graphics;
1586: - man pages are updated;
1587: - evaluation() is modified to perform evaluation of expressions that contain
1588: '=';
1589: - a minor bug is fixed in AXES intrinsic;
1590: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1591: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1592: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1593: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1594: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1610: - SCLS is added;
1611: - DRWS now uses COLS to draw 2D graphics;
1612: - PPAR and SPAR are written. SPAR returns a list that contains the
1613: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1614: statistical variable, or "DISABLED" if its type is not one of the type of
1615: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1616: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1617: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1618: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1619: disabled. Arguments of EXTERNAL are case sensitive because the external
1620: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1621: of known external functions but add the new list to the last. { "all" }
1622: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1623: external names of the known functions;
1624: - mkrplso.in is modified.
1625: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1626: - vim syntax file is upgraded;
1627: - a minor mistake is fixed in recherche_instruction_suivante();
1628: - some minor memory leaks are fixed in recherche_type() function. They only
1629: occurs when a syntax error is detected;

1631: - INCR and DECR are written (with integer or variable argument);
1632: - CSWP and RSWP are added and tested;
1633: - a minor bug is fixed in analyse.c;
1634: - DEBIAN/control is added to build debian package;
1635: - SCALE is fixed and improved ("automatic" keyword);
1636: - PUTC and PUTR new intrinsics are added.
1637: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1638: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1639: VISIT does not find a name in level 1;
1640: - configure.in script is modified to add a new test (--enable-debug
1641: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1642: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1643: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1644: 'MATRIX' { 2 2 3 } GETR;
1645: - LOGSCALE intrinsic is improved and now, it can be used as
1646: { "main" "auxiliary" X Y } LOGSCALE;
1647: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1648: same than AXES:
1649: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1650: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1651: { { -10 10 } "automatic" } SCALE.
1652: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1653: because it changes only the dimension of the screen. To have a logarithmic
1654: scale, you must use LOGSCALE intrinsic:
1655: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1656: screen on second scale;
1657: - { X X } autoscale and { Y Y } logscale are now invalid;
1658: - *D is added (depth multiplication, for 3D graphics);
1659: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1660: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1661: - a major bug is fixed in GETI instrinsic when it is used with a name
1662: that contains a matrix or a vector (bad upper bounds conditions in
1663: incrementation);
1664: - DISP intrinsic now uses the 33-th flag. When it is not set
1665: (default), a final carriage return is sent to the terminal;
1666: - AXES intrinsic only takes a list that can contains the keywork
1667: "main" or "auxiliary". Before this modification, this keyword was in
1668: the first stack level;
1669: - vim syntax file is upgraded;
1670: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1671: option;
1672: - LAST is now disabled in the main loop of INT intrinsic;
1673: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1674: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1675: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1676: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1677: in 0);
1678: - LAST is disabled in the main loop of DRAW intrinsic;
1679: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1680: evaluation of an equation, the system stack is returned corrupted to the
1681: sequencer;
1682: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1683: of a loop are not integer or real.
1684: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1685: - the compilation stage aborts with an error message when two definitions
1686: have the same name. To improve the compilation() subroutine, I have to
1687: add some tests in gestion_variables.c;
1688: - recherche_type() subroutine ad some other connex subroutines are improved.
1689: Now, some syntax errors about object are caught and do not perform sequencer
1690: hangup;

1692: - Makefile.am's and configure.in scripts are improved.
1693: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1694: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1695: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1696: the boxwidth, 1 by default);
1697: - recherche_type() is rewritten to be faster;
1698: - gsl is upgraded (release 1.3);
1699: - ncurses is upgraded and patched (release 5.3);
1700: - recherche_instruction_suivante() is fixed (string research with included
1701: '"') and rewritten to be faster;
1702: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1703: segfault.
1704: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1712: - a minor bug is fixed in evaluation subroutine;
1713: - vim syntax file is improved;
1714: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1715: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1716: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1717: is a quick and dirty workaround...);
1718: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1719: - rplconvert is improved.
1720: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1736: Now, an expression such as 'A+' returns an error when it is analyzed;
1737: - VISIT intrinsic is added;
1738: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1739: normal mode.

1827: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1828: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1829: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1830: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1831: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1832:
1833: Newton:[~/rpl/rpl] > time make install
1834: ...
1835: real 338m39.623s
1836: user 324m32.290s
1837: sys 10m47.380s
1838: Newton:[~/rpl/rpl] >
1839:
1840: I don't know if you will compile this language on old worstations, but
1841: it is usable ;-) ;
1842: - SYSEVAL is improved. An external program can be called without any shell.
1843: Thus, even if the sticky bit is set, RPL/2 can not give a shell root when
