289: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
290: "ALL" IMPLICIT when it runs in interactive mode;
291: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
292: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
293: to use SAVE to manipulate global variables;
294: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
295: subroutines;
296: - fix major memory access violation in evaluation subroutine. Only occurs
297: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
298: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
299: when X was a vector or a table.

330: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
331: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
332: corruption. As internal memory management have been improved, a best fit
333: allocator like ptmalloc3 is not required anymore;
334: - gnuplot is upgraded to 4.4.1;
335: - deadlock is fixed in signal handlers: same mutex was used in standard
336: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
337: and signal handlers. A new signal handler specific mutex is added;
338: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
339: that has to be evaluated by ->NUM;
340: - rplfile build process is modify to be sure that rplfile is not modified
341: after rpl build stage (to be sure that rplfile checksum is not modified after

349: parent process was not interrupted if it is not group master process. To fix
350: this bug, SIGINJECT signal is not sent by child process but by control thread
351: in parent process;
352: - minor bug is fixed in data injection (POKE) that does not work as expected
353: when child process is protected by NRPROC.
354: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
355: - --enable-sysv-sems is added to configure script to use SystemV semaphores
356: functions instead of POSIX functions. This function is disabled or forced on
357: systems that does not provide correct POSIX or SysV semaphores subsystem;
358: - a dirty but not quick patch is written to workaround broken siginfo
359: structures. This patch has been successfully tested. It uses a segment of
360: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
361: (Unix PID);
362: - some OpenBSD's hacks are added;
363: - broken siginfo->si_pid field is now checked by configure script;

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

392: caught;
393: - major bug is fixed in analyse() subroutine. When evaluation() returned error
394: in a compiled program, analyse() caught this error twice and randomly aborted
395: with a segmentation error;
396: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
397: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
398: signals;

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

448: sequenceur(). They only occured when syntax error were caught;
449: - IMPLICIT causes execution error instead system error;
450: - Hurd support is improved but currently broken because Hurd does not support
451: SIG_INFO. Work in progress;
452: - OpenBSD specific support is removed from sources;
453: - support for Mac OS X and Windows/Cygwin is added.

494: - in formatted file, string format returned a variable length string even if
495: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
496: a variable length string and 'CHARACTER*(n)' a fixed length string;
497: - keyed access files support is added. Currently, only formatted files are
498: supported;
499: - direct access files support is added. Currenlty, these files can only be used

505: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
506: each execution (md5 and sha1 sums) to enhance security. If one of these tools
507: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
508: on a non recoverable system error;
509: - openssl and sqlite3 libraries are added;
510: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
511: variable indicates RPL/2 root directory. If it is not set, root path
512: is given by configure script (d_exec_path);
513: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

547: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
548: signals sent to main process were not caught because DAEMON did not replace
549: old pid by new one;
550: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
551: evaluation when an error is reported from a subroutine in another subroutine.
552: For example, error was not caught in following program when it is executed with

559: script file contains a multibyte character;
560: - IN intrinsic is added;
561: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
562: returned false ;

584: locales;
585: - '"' can now be used in strings ("\"");
586: - iconv is called with -c in preprocessor stage. It is done to write

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

619: a freed semaphore and corrupts heap;
620: - CLRERR is added to erase previous errors;
621: - ERRN and ERRM return exception message and number;
622: - major bug is fixed in interruptions.c. All signal are now bufferised

1074: - external wrapper (rplplot) is written to force usage of gnuplot provided
1075: by RPL/2 if it is built during build process. If this build does not exist,
1076: it tries to launch regular gnuplot;
1077: - gnuplot is added to source tree to avoid some trouble between preinstalled
1078: gnuplot and release used by RPL/2. This addition to source tree is

1126: static variable can be transformed into volatile with VOLATILE.
1127: With STATIC, next variables created by '->' are static;
1128: - PROTECT and UNPROTECT are added to protect variables against write
1129: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1130: versions of PROTECT and UNPROTECT that only deal with global variables
1131: (see RCL/SAVE);
1132: - variable management routines have been rewritten. The new ones are
1133: uncompatible with the old ones. Before these changes, a local variable
1134: was exported to a child subroutine, but cannot be modified into this
1135: child subroutine. Now, a local variable is accessible only in its subroutine;
1136: - SAVE intrinsic is added to manipulate global variables;

1149: mutexes and several terminated child process cannot be closed by the
1150: operating system);
1151: - minor bug fixed in SCLS (mistake between main and auxiliary axes);
1152: - variables are now written in rpl-core file;
1153: - NEG is modified to return 0 instead -0 when its argument is real or complex
1154: number;
1155: - ROW+ intrinsic can now be used on empty matrix without dimension error:

1520: - a minor bug (in last stack) is fixed in AXES intrinsic
1521: - flag 52 is used to automatically update graphics;
1522: - man pages are updated;
1523: - evaluation() is modified to perform evaluation of expressions that contain
1524: '=';
1525: - a minor bug is fixed in AXES intrinsic;
1526: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1527: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1528: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1529: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1530: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;
1531: - PLOTTER is added to draw statistical clouds with lines;
1532: - C and H source files now include vim parameters;
1533: - vim syntax file is modified to include new intrinsics;
1534: - static archive is modified to include all required libraries needed by
1535: RPL/2.
1536: * Sun May 4 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6i (RPL/2)
1537: - '=' is added and tested;
1538: - XCOL and YCOL are added;
1539: - a minor bug in analyse_syntaxique() is fixed;
1540: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1541: structure. ELSE is modified to return an error when ELSE appears in
1542: an ELSE/END structure;
1543: - a major bug is fixed in CYCLE;
1544: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1545: sequencer continues after the end of this loop;
1546: - SCLS is added;
1547: - DRWS now uses COLS to draw 2D graphics;
1548: - PPAR and SPAR are written. SPAR returns a list that contains the
1549: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1550: statistical variable, or "DISABLED" if its type is not one of the type of
1551: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1552: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1553: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1554: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1555: disabled. Arguments of EXTERNAL are case sensitive because the external
1556: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1557: of known external functions but add the new list to the last. { "all" }
1558: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1559: external names of the known functions;
1560: - mkrplso.in is modified.
1561: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1562: - vim syntax file is upgraded;
1563: - a minor mistake is fixed in recherche_instruction_suivante();
1564: - some minor memory leaks are fixed in recherche_type() function. They only
1565: occurs when a syntax error is detected;
1566: - #error and #warning preprocessor macros are added;
1567: - INCR and DECR are written (with integer or variable argument);
1568: - CSWP and RSWP are added and tested;
1569: - a minor bug is fixed in analyse.c;
1570: - DEBIAN/control is added to build debian package;
1571: - SCALE is fixed and improved ("automatic" keyword);
1572: - PUTC and PUTR new intrinsics are added.
1573: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1574: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1575: VISIT does not find a name in level 1;
1576: - configure.in script is modified to add a new test (--enable-debug
1577: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1578: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1579: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1580: 'MATRIX' { 2 2 3 } GETR;
1581: - LOGSCALE intrinsic is improved and now, it can be used as
1582: { "main" "auxiliary" X Y } LOGSCALE;
1583: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1584: same than AXES:
1585: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1586: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1587: { { -10 10 } "automatic" } SCALE.
1588: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1589: because it changes only the dimension of the screen. To have a logarithmic
1590: scale, you must use LOGSCALE intrinsic:
1591: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1592: screen on second scale;
1593: - { X X } autoscale and { Y Y } logscale are now invalid;
1594: - *D is added (depth multiplication, for 3D graphics);
1595: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1596: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1597: - a major bug is fixed in GETI instrinsic when it is used with a name
1598: that contains a matrix or a vector (bad upper bounds conditions in
1599: incrementation);
1600: - DISP intrinsic now uses the 33-th flag. When it is not set
1601: (default), a final carriage return is sent to the terminal;
1602: - AXES intrinsic only takes a list that can contains the keywork
1603: "main" or "auxiliary". Before this modification, this keyword was in
1604: the first stack level;
1605: - vim syntax file is upgraded;
1606: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1607: option;
1608: - LAST is now disabled in the main loop of INT intrinsic;
1609: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1610: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1611: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1612: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1613: in 0);
1614: - LAST is disabled in the main loop of DRAW intrinsic;
1615: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1616: evaluation of an equation, the system stack is returned corrupted to the
1617: sequencer;
1618: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1619: of a loop are not integer or real.
1620: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1621: - the compilation stage aborts with an error message when two definitions
1622: have the same name. To improve the compilation() subroutine, I have to
1623: add some tests in gestion_variables.c;
1624: - recherche_type() subroutine ad some other connex subroutines are improved.
1625: Now, some syntax errors about object are caught and do not perform sequencer
1626: hangup;

1628: - Makefile.am's and configure.in scripts are improved.
1629: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1630: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1631: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1632: the boxwidth, 1 by default);
1633: - recherche_type() is rewritten to be faster;
1634: - gsl is upgraded (release 1.3);
1635: - ncurses is upgraded and patched (release 5.3);
1636: - recherche_instruction_suivante() is fixed (string research with included
1637: '"') and rewritten to be faster;

1648: - a minor bug is fixed in evaluation subroutine;
1649: - vim syntax file is improved;
1650: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1651: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1652: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1653: is a quick and dirty workaround...);
1654: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1655: - rplconvert is improved.

1765: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1766: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1767: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1768:
1769: Newton:[~/rpl/rpl] > time make install
