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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

1137: - external wrapper (rplplot) is written to force usage of gnuplot provided
1138: by RPL/2 if it is built during build process. If this build does not exist,
1139: it tries to launch regular gnuplot;
1140: - gnuplot is added to source tree to avoid some trouble between preinstalled
1141: gnuplot and release used by RPL/2. This addition to source tree is
1142: required by some incompatibility between gnuplot releases;
1143: - Lapack is upgraded to 3.1.1 release;
1144: - GSL is upgraded to 1.9 revision;

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

1537: - a minor bug in vim syntax file is fixed (CYCLE and EXIT intrinsics);
1538: - a minor bug is discovered in analyse_algebrique(). Now, expression
1539: such as 'A+Z AND 2' or '(A+Z) AND 2' are correctly parsed.

1559: 1: x;
1560: - ->Q intrinsic is added;
1561: - major bug is fixed in C->R intrinsic;
1562: - ROW+ and ROW- are added and tested;
1563: - COL+ and COL- are added and tested. Syntax:
1564: 3: matrix
1565: 2: integer (number of column to be inserted)
1566: 1: column matrix to be inserted;
1567: - major bug was discovered in interface_gnuplot(). It only occurs when

1576: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1577: - SLICESCALE intrinsic is added. Its syntax is
1578: { "automatic" nb_of_levels }
1579: { "discrete" l1 l2 l3 ... }
1580: { "incremental" start incr }
1581: { "incremental" start incr end }
1582: { "automatic" } (default);

1584: - flag 52 is used to automatically update graphics;
1585: - man pages are updated;
1586: - evaluation() is modified to perform evaluation of expressions that contain
1587: '=';
1588: - a minor bug is fixed in AXES intrinsic;
1589: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1590: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1591: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1592: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1593: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1604: structure. ELSE is modified to return an error when ELSE appears in
1605: an ELSE/END structure;
1606: - a major bug is fixed in CYCLE;

1609: - SCLS is added;
1610: - DRWS now uses COLS to draw 2D graphics;
1611: - PPAR and SPAR are written. SPAR returns a list that contains the
1612: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1613: statistical variable, or "DISABLED" if its type is not one of the type of
1614: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1615: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1616: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1617: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1618: disabled. Arguments of EXTERNAL are case sensitive because the external
1619: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1620: of known external functions but add the new list to the last. { "all" }
1621: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1622: external names of the known functions;
1623: - mkrplso.in is modified.
1624: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1625: - vim syntax file is upgraded;
1626: - a minor mistake is fixed in recherche_instruction_suivante();
1627: - some minor memory leaks are fixed in recherche_type() function. They only
1628: occurs when a syntax error is detected;

1630: - INCR and DECR are written (with integer or variable argument);
1631: - CSWP and RSWP are added and tested;
1632: - a minor bug is fixed in analyse.c;
1633: - DEBIAN/control is added to build debian package;
1634: - SCALE is fixed and improved ("automatic" keyword);
1635: - PUTC and PUTR new intrinsics are added.
1636: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1637: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1638: VISIT does not find a name in level 1;
1639: - configure.in script is modified to add a new test (--enable-debug
1640: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1641: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1642: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1643: 'MATRIX' { 2 2 3 } GETR;
1644: - LOGSCALE intrinsic is improved and now, it can be used as
1645: { "main" "auxiliary" X Y } LOGSCALE;
1646: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1647: same than AXES:
1648: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1649: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1650: { { -10 10 } "automatic" } SCALE.
1651: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1652: because it changes only the dimension of the screen. To have a logarithmic
1653: scale, you must use LOGSCALE intrinsic:
1654: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1655: screen on second scale;
1656: - { X X } autoscale and { Y Y } logscale are now invalid;
1657: - *D is added (depth multiplication, for 3D graphics);
1658: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1659: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1660: - a major bug is fixed in GETI instrinsic when it is used with a name
1661: that contains a matrix or a vector (bad upper bounds conditions in
1662: incrementation);
1663: - DISP intrinsic now uses the 33-th flag. When it is not set
1664: (default), a final carriage return is sent to the terminal;
1665: - AXES intrinsic only takes a list that can contains the keywork
1666: "main" or "auxiliary". Before this modification, this keyword was in
1667: the first stack level;
1668: - vim syntax file is upgraded;
1669: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1670: option;
1671: - LAST is now disabled in the main loop of INT intrinsic;
1672: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1673: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1674: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1675: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1676: in 0);
1677: - LAST is disabled in the main loop of DRAW intrinsic;
1678: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1679: evaluation of an equation, the system stack is returned corrupted to the
1680: sequencer;
1681: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1682: of a loop are not integer or real.
1683: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1684: - the compilation stage aborts with an error message when two definitions
1685: have the same name. To improve the compilation() subroutine, I have to
1686: add some tests in gestion_variables.c;
1687: - recherche_type() subroutine ad some other connex subroutines are improved.
1688: Now, some syntax errors about object are caught and do not perform sequencer
1689: hangup;
1690: - readline is upgraded (minor compilation bug with recent gcc);
1691: - Makefile.am's and configure.in scripts are improved.
1692: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1693: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1694: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1695: the boxwidth, 1 by default);
1696: - recherche_type() is rewritten to be faster;
1697: - gsl is upgraded (release 1.3);
1698: - ncurses is upgraded and patched (release 5.3);
1699: - recherche_instruction_suivante() is fixed (string research with included
1700: '"') and rewritten to be faster;
1701: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1702: segfault.
1703: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1711: - a minor bug is fixed in evaluation subroutine;
1712: - vim syntax file is improved;
1713: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1714: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1715: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1716: is a quick and dirty workaround...);
1717: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1718: - rplconvert is improved.
1719: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1735: Now, an expression such as 'A+' returns an error when it is analyzed;
1736: - VISIT intrinsic is added;
1737: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1738: normal mode.

1826: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1827: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1828: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1829: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1830: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1831:
1832: Newton:[~/rpl/rpl] > time make install
1833: ...
1834: real 338m39.623s
1835: user 324m32.290s
1836: sys 10m47.380s
1837: Newton:[~/rpl/rpl] >
1838:
1839: I don't know if you will compile this language on old worstations, but
1840: it is usable ;-) ;
1841: - SYSEVAL is improved. An external program can be called without any shell.
