363: subroutines;
364: - fix major memory access violation in evaluation subroutine. Only occurs
365: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;

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

414: ABORT now works on eComStation;
415: - sqlite is upgraded to 3.7.2;
416: - bug is fixed in software interrupts. When both process have different PID,
417: parent process was not interrupted if it is not group master process. To fix
418: this bug, SIGINJECT signal is not sent by child process but by control thread
419: in parent process;
420: - minor bug is fixed in data injection (POKE) that does not work as expected
421: when child process is protected by NRPROC.
422: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
423: - --enable-sysv-sems is added to configure script to use SystemV semaphores
424: functions instead of POSIX functions. This function is disabled or forced on
425: systems that does not provide correct POSIX or SysV semaphores subsystem;
426: - a dirty but not quick patch is written to workaround broken siginfo
427: structures. This patch has been successfully tested. It uses a segment of
428: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
429: (Unix PID);
430: - some OpenBSD's hacks are added;
431: - broken siginfo->si_pid field is now checked by configure script;

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

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

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

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

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

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

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

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

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

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

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

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

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

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

989: When configure is called with --disable-encoding-autodetection, make does not
990: try to detect source encoding. Please, do not use if RPL/2 can be built
991: without this option !
992: - new garbage collector (and more efficient) is written;

1142: - external wrapper (rplplot) is written to force usage of gnuplot provided
1143: by RPL/2 if it is built during build process. If this build does not exist,
1144: it tries to launch regular gnuplot;
1145: - gnuplot is added to source tree to avoid some trouble between preinstalled

1522: (less parenthesis);
1523: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1524: on Debian distribution, but since cpp is in the default path, RPL/2 works
1525: fine...);
1526: - NOT is not correctly formatted in formateur.c:
1527: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1528: with a NOTZ function !
1529: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1530: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1531: if the main loop is in a program;
1532: - RPL/2 is tested with efence and valgrind;
1533: - configure.in script is modified;
1534: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1535: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1536: another gcc bug...
1537: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)
1538: - EXIT is fixed. Now, it is possible to use EXIT in an expression when the
1539: main loop is in a program;

1566: - major bug is fixed in C->R intrinsic;
1567: - ROW+ and ROW- are added and tested;
1568: - COL+ and COL- are added and tested. Syntax:

1570: 2: integer (number of column to be inserted)
1571: 1: column matrix to be inserted;
1572: - major bug was discovered in interface_gnuplot(). It only occurs when

1581: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1582: - SLICESCALE intrinsic is added. Its syntax is
1583: { "automatic" nb_of_levels }
1584: { "discrete" l1 l2 l3 ... }
1585: { "incremental" start incr }
1586: { "incremental" start incr end }
1587: { "automatic" } (default);
1588: - a minor bug (in last stack) is fixed in AXES intrinsic
1589: - flag 52 is used to automatically update graphics;
1590: - man pages are updated;
1591: - evaluation() is modified to perform evaluation of expressions that contain
1592: '=';
1593: - a minor bug is fixed in AXES intrinsic;
1594: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1595: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1596: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1597: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1598: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1614: - SCLS is added;
1615: - DRWS now uses COLS to draw 2D graphics;
1616: - PPAR and SPAR are written. SPAR returns a list that contains the
1617: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1618: statistical variable, or "DISABLED" if its type is not one of the type of
1619: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1620: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1621: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1622: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1623: disabled. Arguments of EXTERNAL are case sensitive because the external
1624: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1625: of known external functions but add the new list to the last. { "all" }
1626: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1627: external names of the known functions;
1628: - mkrplso.in is modified.
1629: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1630: - vim syntax file is upgraded;
1631: - a minor mistake is fixed in recherche_instruction_suivante();
1632: - some minor memory leaks are fixed in recherche_type() function. They only
1633: occurs when a syntax error is detected;

1635: - INCR and DECR are written (with integer or variable argument);
1636: - CSWP and RSWP are added and tested;
1637: - a minor bug is fixed in analyse.c;
1638: - DEBIAN/control is added to build debian package;
1639: - SCALE is fixed and improved ("automatic" keyword);
1640: - PUTC and PUTR new intrinsics are added.
1641: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1642: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1643: VISIT does not find a name in level 1;
1644: - configure.in script is modified to add a new test (--enable-debug
1645: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1646: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1647: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1648: 'MATRIX' { 2 2 3 } GETR;
1649: - LOGSCALE intrinsic is improved and now, it can be used as
1650: { "main" "auxiliary" X Y } LOGSCALE;
1651: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1652: same than AXES:
1653: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1654: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1655: { { -10 10 } "automatic" } SCALE.
1656: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1657: because it changes only the dimension of the screen. To have a logarithmic
1658: scale, you must use LOGSCALE intrinsic:
1659: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1660: screen on second scale;
1661: - { X X } autoscale and { Y Y } logscale are now invalid;
1662: - *D is added (depth multiplication, for 3D graphics);
1663: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1664: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1665: - a major bug is fixed in GETI instrinsic when it is used with a name
1666: that contains a matrix or a vector (bad upper bounds conditions in
1667: incrementation);
1668: - DISP intrinsic now uses the 33-th flag. When it is not set
1669: (default), a final carriage return is sent to the terminal;
1670: - AXES intrinsic only takes a list that can contains the keywork
1671: "main" or "auxiliary". Before this modification, this keyword was in
1672: the first stack level;
1673: - vim syntax file is upgraded;
1674: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1675: option;
1676: - LAST is now disabled in the main loop of INT intrinsic;
1677: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1678: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1679: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1680: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1681: in 0);
1682: - LAST is disabled in the main loop of DRAW intrinsic;
1683: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1684: evaluation of an equation, the system stack is returned corrupted to the
1685: sequencer;
1686: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1687: of a loop are not integer or real.
1688: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1689: - the compilation stage aborts with an error message when two definitions
1690: have the same name. To improve the compilation() subroutine, I have to
1691: add some tests in gestion_variables.c;
1692: - recherche_type() subroutine ad some other connex subroutines are improved.
1693: Now, some syntax errors about object are caught and do not perform sequencer
1694: hangup;

1696: - Makefile.am's and configure.in scripts are improved.
1697: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1698: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1699: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1700: the boxwidth, 1 by default);
1701: - recherche_type() is rewritten to be faster;
1702: - gsl is upgraded (release 1.3);
1703: - ncurses is upgraded and patched (release 5.3);
1704: - recherche_instruction_suivante() is fixed (string research with included
1705: '"') and rewritten to be faster;
1706: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1707: segfault.
1708: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1716: - a minor bug is fixed in evaluation subroutine;
1717: - vim syntax file is improved;
1718: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1719: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1720: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1721: is a quick and dirty workaround...);
1722: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1723: - rplconvert is improved.
1724: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1740: Now, an expression such as 'A+' returns an error when it is analyzed;
1741: - VISIT intrinsic is added;
1742: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1743: normal mode.

1831: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1832: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1833: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1834: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1835: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1836:
1837: Newton:[~/rpl/rpl] > time make install
1838: ...
1839: real 338m39.623s
1840: user 324m32.290s
1841: sys 10m47.380s
1842: Newton:[~/rpl/rpl] >
1843:
1844: I don't know if you will compile this language on old worstations, but
1845: it is usable ;-) ;
1846: - SYSEVAL is improved. An external program can be called without any shell.
1847: Thus, even if the sticky bit is set, RPL/2 can not give a shell root when
