330: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
331: "ALL" IMPLICIT when it runs in interactive mode;
332: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
333: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
334: to use SAVE to manipulate global variables;
335: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
336: subroutines;
337: - fix major memory access violation in evaluation subroutine. Only occurs
338: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
339: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
340: when X was a vector or a table.

372: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
373: corruption. As internal memory management have been improved, a best fit
374: allocator like ptmalloc3 is not required anymore;
375: - gnuplot is upgraded to 4.4.1;
376: - deadlock is fixed in signal handlers: same mutex was used in standard
377: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
378: and signal handlers. A new signal handler specific mutex is added;
379: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
380: that has to be evaluated by ->NUM;
381: - rplfile build process is modify to be sure that rplfile is not modified
382: after rpl build stage (to be sure that rplfile checksum is not modified after

391: this bug, SIGINJECT signal is not sent by child process but by control thread
392: in parent process;
393: - minor bug is fixed in data injection (POKE) that does not work as expected
394: when child process is protected by NRPROC.
395: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
396: - --enable-sysv-sems is added to configure script to use SystemV semaphores
397: functions instead of POSIX functions. This function is disabled or forced on
398: systems that does not provide correct POSIX or SysV semaphores subsystem;
399: - a dirty but not quick patch is written to workaround broken siginfo
400: structures. This patch has been successfully tested. It uses a segment of

425: variable was created and when a local variable existed with the same name,
426: computed address of global variable was wrong;
427: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
428: is forced in front of all libraries.

435: in a compiled program, analyse() caught this error twice and randomly aborted
436: with a segmentation error;
437: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
438: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
439: signals;

466: process;
467: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
468: discovered in Solaris thread safe allocators (libmalloc and libumem) that

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

534: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
535: - in formatted file, string format returned a variable length string even if
536: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
537: a variable length string and 'CHARACTER*(n)' a fixed length string;
538: - keyed access files support is added. Currently, only formatted files are
539: supported;
540: - direct access files support is added. Currenlty, these files can only be used
541: in formatted mode;

543: in string are escaped;
544: - all formatted files are now converted into UTF-8;
545: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
546: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
547: each execution (md5 and sha1 sums) to enhance security. If one of these tools
548: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
549: on a non recoverable system error;
550: - openssl and sqlite3 libraries are added;
551: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
552: variable indicates RPL/2 root directory. If it is not set, root path
553: is given by configure script (d_exec_path);
554: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

588: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
589: signals sent to main process were not caught because DAEMON did not replace
590: old pid by new one;
591: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
592: evaluation when an error is reported from a subroutine in another subroutine.
593: For example, error was not caught in following program when it is executed with
594: -p option :
595: TEST << iferr TEST2 then end >>
596: TEST2 << 0 inv >>
597: - major bug is fixed in variable management. Some local variables were
598: seen as global ones;

600: script file contains a multibyte character;
601: - IN intrinsic is added;
602: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
603: returned false ;
604: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
605: programs;
606: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
607: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
608: strings were never closed;
609: - some bugs have been fixed in file management;

614: encountered at end of block, subroutine aborts with an execution error;
615: - major bug is fixed in OPEN (TCP/IPv4 sockets).
616: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
617: - DISP now locks stdout;
618: - rpliconv is added to replace standard iconv provided by operating system.
619: Indeed, conversion between different encodages requires transliteration
620: that is not offered by some iconv utility;
621: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
622: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

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

659: was called before a pending interruption5 (SIGFSTOP), signal handler uses
660: a freed semaphore and corrupts heap;
661: - CLRERR is added to erase previous errors;
662: - ERRN and ERRM return exception message and number;
663: - major bug is fixed in interruptions.c. All signal are now bufferised
664: when semaphore_liste_threads is null to avoid deadlock. This bug only
665: occured when STOP was sent to a dying thread or process (when this thread or
666: process was running retrait_thread());
667: - matrix rank is computed before matrix inversion;
668: - file locks are added to stdin and stdout. stderr is not locked because
669: all messages written by signal handlers are sent to stderr;

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

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

812: that all programs that worked with old SQL intrinsic can now work with
813: SQLQUERY. With all new programs, you can open a real connection to databases;
814: - NRPROC is added. This new intrinsic is used to catch error from child
815: process. Without NRPROC, any errors returned by child process cause
816: main process to abort;
817: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
818: starts a new process). There are no mutexes in RPL/2 because all spawned process
819: use specific context. Nevertheless, shared variables and associated mutexes
820: should be added;
821: - -D flag and DAEMONIZE intrinsic have been added;

961: - as old file program was bugged, a new option is added to configure script.
962: When configure is called with --disable-encoding-autodetection, make does not
963: try to detect source encoding. Please, do not use if RPL/2 can be built
964: without this option !
965: - new garbage collector (and more efficient) is written;

1114: - HELP function is rewritten to be more friendly (a la OpenVMS);
1115: - external wrapper (rplplot) is written to force usage of gnuplot provided
1116: by RPL/2 if it is built during build process. If this build does not exist,
1117: it tries to launch regular gnuplot;
1118: - gnuplot is added to source tree to avoid some trouble between preinstalled
1119: gnuplot and release used by RPL/2. This addition to source tree is
1120: required by some incompatibility between gnuplot releases;

1554: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1555: - SLICESCALE intrinsic is added. Its syntax is
1556: { "automatic" nb_of_levels }
1557: { "discrete" l1 l2 l3 ... }
1558: { "incremental" start incr }
1559: { "incremental" start incr end }
1560: { "automatic" } (default);

1562: - flag 52 is used to automatically update graphics;
1563: - man pages are updated;
1564: - evaluation() is modified to perform evaluation of expressions that contain
1565: '=';
1566: - a minor bug is fixed in AXES intrinsic;

1568: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1569: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1570: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1571: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1587: - SCLS is added;
1588: - DRWS now uses COLS to draw 2D graphics;
1589: - PPAR and SPAR are written. SPAR returns a list that contains the
1590: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1591: statistical variable, or "DISABLED" if its type is not one of the type of
1592: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1593: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1594: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1595: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1596: disabled. Arguments of EXTERNAL are case sensitive because the external
1597: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1598: of known external functions but add the new list to the last. { "all" }
1599: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1600: external names of the known functions;
1601: - mkrplso.in is modified.
1602: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1603: - vim syntax file is upgraded;
1604: - a minor mistake is fixed in recherche_instruction_suivante();
1605: - some minor memory leaks are fixed in recherche_type() function. They only

1613: - PUTC and PUTR new intrinsics are added.
1614: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1615: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1616: VISIT does not find a name in level 1;
1617: - configure.in script is modified to add a new test (--enable-debug
1618: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1619: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1620: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1621: 'MATRIX' { 2 2 3 } GETR;
1622: - LOGSCALE intrinsic is improved and now, it can be used as
1623: { "main" "auxiliary" X Y } LOGSCALE;
1624: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1625: same than AXES:
1626: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1627: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1628: { { -10 10 } "automatic" } SCALE.
1629: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1630: because it changes only the dimension of the screen. To have a logarithmic
1631: scale, you must use LOGSCALE intrinsic:
1632: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1633: screen on second scale;
1634: - { X X } autoscale and { Y Y } logscale are now invalid;
1635: - *D is added (depth multiplication, for 3D graphics);
1636: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1637: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1638: - a major bug is fixed in GETI instrinsic when it is used with a name
1639: that contains a matrix or a vector (bad upper bounds conditions in
1640: incrementation);
1641: - DISP intrinsic now uses the 33-th flag. When it is not set
1642: (default), a final carriage return is sent to the terminal;
1643: - AXES intrinsic only takes a list that can contains the keywork
1644: "main" or "auxiliary". Before this modification, this keyword was in
1645: the first stack level;
1646: - vim syntax file is upgraded;
1647: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1648: option;
1649: - LAST is now disabled in the main loop of INT intrinsic;
1650: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1651: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1652: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1653: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1654: in 0);
1655: - LAST is disabled in the main loop of DRAW intrinsic;
1656: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1657: evaluation of an equation, the system stack is returned corrupted to the
1658: sequencer;
1659: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1660: of a loop are not integer or real.
1661: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1669: - Makefile.am's and configure.in scripts are improved.
1670: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1671: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1672: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1673: the boxwidth, 1 by default);
1674: - recherche_type() is rewritten to be faster;
1675: - gsl is upgraded (release 1.3);
1676: - ncurses is upgraded and patched (release 5.3);
1677: - recherche_instruction_suivante() is fixed (string research with included
1678: '"') and rewritten to be faster;

1689: - a minor bug is fixed in evaluation subroutine;
1690: - vim syntax file is improved;
1691: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1692: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1693: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1694: is a quick and dirty workaround...);
1695: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1696: - rplconvert is improved.

1804: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1805: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1806: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1807: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1808: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1809:
1810: Newton:[~/rpl/rpl] > time make install
1811: ...
1812: real 338m39.623s
1813: user 324m32.290s
