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

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

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

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

435: when this structure is included in IFERR/THEN/END structure and when an error is
436: caught;
437: - major bug is fixed in analyse() subroutine. When evaluation() returned error
438: in a compiled program, analyse() caught this error twice and randomly aborted
439: with a segmentation error;
440: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
441: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
442: signals;
443: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
444: matrix.

468: - major bug is fixed in sql support. SQL connections were closed in all chield
469: process;
470: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
471: discovered in Solaris thread safe allocators (libmalloc and libumem) that
472: are first fit class allocators. Solaris libmtmalloc works better and is
473: a best fit class allocator but its performance is poor than ptmalloc3
474: performance;

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

537: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
538: - in formatted file, string format returned a variable length string even if
539: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
540: a variable length string and 'CHARACTER*(n)' a fixed length string;
541: - keyed access files support is added. Currently, only formatted files are
542: supported;
543: - direct access files support is added. Currenlty, these files can only be used
544: in formatted mode;
545: - virtual variables are now writte in UTF-8 and all special characters
546: in string are escaped;
547: - all formatted files are now converted into UTF-8;
548: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
549: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
550: each execution (md5 and sha1 sums) to enhance security. If one of these tools
551: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
552: on a non recoverable system error;
553: - openssl and sqlite3 libraries are added;
554: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
555: variable indicates RPL/2 root directory. If it is not set, root path
556: is given by configure script (d_exec_path);
557: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

591: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
592: signals sent to main process were not caught because DAEMON did not replace
593: old pid by new one;
594: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
595: evaluation when an error is reported from a subroutine in another subroutine.
596: For example, error was not caught in following program when it is executed with
597: -p option :
598: TEST << iferr TEST2 then end >>
599: TEST2 << 0 inv >>
600: - major bug is fixed in variable management. Some local variables were
601: seen as global ones;
602: - major bug is fixed in rplcore. Rplcore entered in dead lock when
603: script file contains a multibyte character;
604: - IN intrinsic is added;
605: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
606: returned false ;
607: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
608: programs;
609: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
610: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
611: strings were never closed;
612: - some bugs have been fixed in file management;

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

627: - fprintf is replaced by some functions that allow transliterations between
628: locales;
629: - '"' can now be used in strings ("\"");
630: - iconv is called with -c in preprocessor stage. It is done to write
631: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
632: - double free is fixed in liberation() (type SQL, only occurs when locale is
633: set);
634: - LOCALIZATION, UCASE and LCASE are added;

644: - pipe() is overwritten by a macro to avoid a system error. Communication
645: between process are done with pipes and these pipes are managed by a
646: specific asynchrone thread. If a script try to create more threads than
647: management thread can destroy, you can quickly achieve maximum number of
648: opened files and pipe() shall return a system error. This macro tries to create
649: pipes. If pipe() function returns an error, macro waits and retries. If
650: number of retries is greater than a hardcoded value, macro returns an error;
651: - major bug (deadlock) is fixed in process and thread management. I hope
652: this bug shall be the last one;
653: - major bug is fixed in DET intrinsic (determinant was computed without LU
654: diagonalization);

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

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

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

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

1118: - external wrapper (rplplot) is written to force usage of gnuplot provided
1119: by RPL/2 if it is built during build process. If this build does not exist,
1120: it tries to launch regular gnuplot;
1121: - gnuplot is added to source tree to avoid some trouble between preinstalled
1122: gnuplot and release used by RPL/2. This addition to source tree is
1123: required by some incompatibility between gnuplot releases;

1557: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1558: - SLICESCALE intrinsic is added. Its syntax is
1559: { "automatic" nb_of_levels }
1560: { "discrete" l1 l2 l3 ... }
1561: { "incremental" start incr }
1562: { "incremental" start incr end }
1563: { "automatic" } (default);

1565: - flag 52 is used to automatically update graphics;
1566: - man pages are updated;
1567: - evaluation() is modified to perform evaluation of expressions that contain
1568: '=';
1569: - a minor bug is fixed in AXES intrinsic;
1570: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1571: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1572: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1573: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1574: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1590: - SCLS is added;
1591: - DRWS now uses COLS to draw 2D graphics;
1592: - PPAR and SPAR are written. SPAR returns a list that contains the
1593: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1594: statistical variable, or "DISABLED" if its type is not one of the type of
1595: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1596: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1597: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1598: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1599: disabled. Arguments of EXTERNAL are case sensitive because the external
1600: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1601: of known external functions but add the new list to the last. { "all" }
1602: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1603: external names of the known functions;
1604: - mkrplso.in is modified.
1605: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1606: - vim syntax file is upgraded;
1607: - a minor mistake is fixed in recherche_instruction_suivante();
1608: - some minor memory leaks are fixed in recherche_type() function. They only

1616: - PUTC and PUTR new intrinsics are added.
1617: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1618: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1619: VISIT does not find a name in level 1;
1620: - configure.in script is modified to add a new test (--enable-debug
1621: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1622: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1623: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1624: 'MATRIX' { 2 2 3 } GETR;
1625: - LOGSCALE intrinsic is improved and now, it can be used as
1626: { "main" "auxiliary" X Y } LOGSCALE;
1627: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1628: same than AXES:
1629: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1630: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1631: { { -10 10 } "automatic" } SCALE.
1632: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1633: because it changes only the dimension of the screen. To have a logarithmic
1634: scale, you must use LOGSCALE intrinsic:
1635: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1636: screen on second scale;
1637: - { X X } autoscale and { Y Y } logscale are now invalid;
1638: - *D is added (depth multiplication, for 3D graphics);
1639: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1640: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1641: - a major bug is fixed in GETI instrinsic when it is used with a name
1642: that contains a matrix or a vector (bad upper bounds conditions in
1643: incrementation);
1644: - DISP intrinsic now uses the 33-th flag. When it is not set
1645: (default), a final carriage return is sent to the terminal;
1646: - AXES intrinsic only takes a list that can contains the keywork
1647: "main" or "auxiliary". Before this modification, this keyword was in
1648: the first stack level;
1649: - vim syntax file is upgraded;
1650: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1651: option;
1652: - LAST is now disabled in the main loop of INT intrinsic;
1653: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1654: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1655: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1656: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1657: in 0);
1658: - LAST is disabled in the main loop of DRAW intrinsic;
1659: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1660: evaluation of an equation, the system stack is returned corrupted to the
1661: sequencer;
1662: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1663: of a loop are not integer or real.
1664: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1672: - Makefile.am's and configure.in scripts are improved.
1673: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1674: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1675: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1676: the boxwidth, 1 by default);
1677: - recherche_type() is rewritten to be faster;
1678: - gsl is upgraded (release 1.3);
1679: - ncurses is upgraded and patched (release 5.3);
1680: - recherche_instruction_suivante() is fixed (string research with included
1681: '"') and rewritten to be faster;

1692: - a minor bug is fixed in evaluation subroutine;
1693: - vim syntax file is improved;
1694: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1695: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1696: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1697: is a quick and dirty workaround...);
1698: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1699: - rplconvert is improved.

1807: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1808: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1809: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1810: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1811: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1812:
1813: Newton:[~/rpl/rpl] > time make install
1814: ...
1815: real 338m39.623s
1816: user 324m32.290s
