253: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
254: "ALL" IMPLICIT when it runs in interactive mode;
255: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
256: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
257: to use SAVE to manipulate global variables;
258: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
259: subroutines;
260: - fix major memory access violation in evaluation subroutine. Only occurs
261: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
262: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
263: when X was a vector or a table.

295: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
296: corruption. As internal memory management have been improved, a best fit
297: allocator like ptmalloc3 is not required anymore;
298: - gnuplot is upgraded to 4.4.1;
299: - deadlock is fixed in signal handlers: same mutex was used in standard
300: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
301: and signal handlers. A new signal handler specific mutex is added;
302: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
303: that has to be evaluated by ->NUM;
304: - rplfile build process is modify to be sure that rplfile is not modified
305: after rpl build stage (to be sure that rplfile checksum is not modified after

314: this bug, SIGINJECT signal is not sent by child process but by control thread
315: in parent process;
316: - minor bug is fixed in data injection (POKE) that does not work as expected
317: when child process is protected by NRPROC.
318: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
319: - --enable-sysv-sems is added to configure script to use SystemV semaphores
320: functions instead of POSIX functions. This function is disabled or forced on
321: systems that does not provide correct POSIX or SysV semaphores subsystem;
322: - a dirty but not quick patch is written to workaround broken siginfo
323: structures. This patch has been successfully tested. It uses a segment of
324: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
325: (Unix PID);
326: - some OpenBSD's hacks are added;

346: a name of RPL/2 routine;
347: - major bug is fixed in global variable creation subroutine. When a global
348: variable was created and when a local variable existed with the same name,
349: computed address of global variable was wrong;
350: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
351: is forced in front of all libraries.

355: when this structure is included in IFERR/THEN/END structure and when an error is
356: caught;
357: - major bug is fixed in analyse() subroutine. When evaluation() returned error
358: in a compiled program, analyse() caught this error twice and randomly aborted
359: with a segmentation error;
360: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
361: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
362: signals;
363: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
364: matrix.

380: - minor memory leak is fixed in OPEN intrinsic (socket);
381: - major bug is fixed in IFERR structure. Only occurs in compiled program;
382: - major bug is fixed in copie_objet() and liberation(). Only concerns
383: format in FCH (file descriptor) and SCK (socket descriptor);
384: - debug routines are improved;
385: - PROCID is added;
386: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
387: and to not use swap;
388: - major bug is fixed in sql support. SQL connections were closed in all chield
389: process;
390: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
391: discovered in Solaris thread safe allocators (libmalloc and libumem) that
392: are first fit class allocators. Solaris libmtmalloc works better and is
393: a best fit class allocator but its performance is poor than ptmalloc3
394: performance;
395: - major bug is fixed in ROW+ intrinsic (new row was not added where it
396: should);
397: - minor bugs are fixed in interruptions.c (semaphores values when error is
398: caught);
399: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
400: created by SPAWN;
401: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
402: ATEXIT. If it receives SIGFABORT, it does not;
403: - ONEXIT is renamed in ATEXIT;
404: - ONEXIT new intrinsic is added.
405: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
406: - major bug is fixed in static and shared variables initialization subroutine.
407: This bug only occurs when RPL/2 tries to create a shared or static variable
408: from an expression;
409: - major bug is fixed in copie_etat_processus(). A field that contains
410: information about shared variable was not copied to new processus structure;
411: - some little memory leaks are fixed in evaluation(), recherche_type() and
412: sequenceur(). They only occured when syntax error were caught;
413: - IMPLICIT causes execution error instead system error;
414: - Hurd support is improved but currently broken because Hurd does not support
415: SIG_INFO. Work in progress;
416: - OpenBSD specific support is removed from sources;
417: - support for Mac OS X and Windows/Cygwin is added.
418: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)
419: - implicit names can now be disabled by new IMPLICIT intrinsic:

456: rplc (RPL/2 compiler).
457: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
458: - in formatted file, string format returned a variable length string even if
459: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
460: a variable length string and 'CHARACTER*(n)' a fixed length string;
461: - keyed access files support is added. Currently, only formatted files are
462: supported;
463: - direct access files support is added. Currenlty, these files can only be used
464: in formatted mode;
465: - virtual variables are now writte in UTF-8 and all special characters
466: in string are escaped;
467: - all formatted files are now converted into UTF-8;
468: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
469: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
470: each execution (md5 and sha1 sums) to enhance security. If one of these tools
471: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
472: on a non recoverable system error;
473: - openssl and sqlite3 libraries are added;
474: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
475: variable indicates RPL/2 root directory. If it is not set, root path
476: is given by configure script (d_exec_path);
477: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
478: - configure.in and makefile.am's are modified to add Cygwin support. Interix

485: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
486: - Makefile.am are modified to authorize parallel builds;
487: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
488: and writes warning to standard output;
489: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)

509: list argument and inexistant elements).
510: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
511: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
512: signals sent to main process were not caught because DAEMON did not replace
513: old pid by new one;
514: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
515: evaluation when an error is reported from a subroutine in another subroutine.
516: For example, error was not caught in following program when it is executed with
517: -p option :
518: TEST << iferr TEST2 then end >>
519: TEST2 << 0 inv >>
520: - major bug is fixed in variable management. Some local variables were
521: seen as global ones;
522: - major bug is fixed in rplcore. Rplcore entered in dead lock when
523: script file contains a multibyte character;
524: - IN intrinsic is added;
525: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
526: returned false ;
527: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
528: programs;
529: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
530: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
531: strings were never closed;
532: - some bugs have been fixed in file management;
533: - RPL/2 can now be run on EBCDIC systems (OS/390);
534: - major bug is fixed in -A command line option (NULL character is missing);
535: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
536: made by blocks (1024 bytes). When an incomplete multibyte sequence is
537: encountered at end of block, subroutine aborts with an execution error;
538: - major bug is fixed in OPEN (TCP/IPv4 sockets).
539: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
540: - DISP now locks stdout;
541: - rpliconv is added to replace standard iconv provided by operating system.
542: Indeed, conversion between different encodages requires transliteration
543: that is not offered by some iconv utility;
544: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
545: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
546: not be found), SYSEVAL enters in a dead lock;
547: - fprintf is replaced by some functions that allow transliterations between
548: locales;
549: - '"' can now be used in strings ("\"");
550: - iconv is called with -c in preprocessor stage. It is done to write
551: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
552: - double free is fixed in liberation() (type SQL, only occurs when locale is
553: set);
554: - LOCALIZATION, UCASE and LCASE are added;
555: - major bug is fixed in EXIT intrinsic that was able to return a false
556: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
557: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
558: used in onLoading from shared library, USE was pushed on stack as algebraic
559: expression;
560: - libiconv is upgraded to 1.13.1;
561: - gnuplot is upgraded to 4.2.6;
562: - gsl is upgraded to 1.13.
563: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
564: - pipe() is overwritten by a macro to avoid a system error. Communication
565: between process are done with pipes and these pipes are managed by a
566: specific asynchrone thread. If a script try to create more threads than
567: management thread can destroy, you can quickly achieve maximum number of
568: opened files and pipe() shall return a system error. This macro tries to create
569: pipes. If pipe() function returns an error, macro waits and retries. If
570: number of retries is greater than a hardcoded value, macro returns an error;
571: - major bug (deadlock) is fixed in process and thread management. I hope
572: this bug shall be the last one;
573: - major bug is fixed in DET intrinsic (determinant was computed without LU
574: diagonalization);
575: - SWAPCNTXT is added;
576: - minor bug is fixed in Makefile.am (licences rule).
577: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
578: - some bugfixes are added in process management;
579: - all process management is rewritten to avoid usage of defunct process
580: or thread number;
581: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
582: was called before a pending interruption5 (SIGFSTOP), signal handler uses
583: a freed semaphore and corrupts heap;
584: - CLRERR is added to erase previous errors;
585: - ERRN and ERRM return exception message and number;
586: - major bug is fixed in interruptions.c. All signal are now bufferised
587: when semaphore_liste_threads is null to avoid deadlock. This bug only
588: occured when STOP was sent to a dying thread or process (when this thread or
589: process was running retrait_thread());
590: - matrix rank is computed before matrix inversion;
591: - file locks are added to stdin and stdout. stderr is not locked because
592: all messages written by signal handlers are sent to stderr;
593: - configure.in script is modified to test gcc version and avoid a bug in
594: gcc older than 4.4;
595: - some benchmarks have been done :

651: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
652: - FORTRAN 77 file management subroutines are rewritten in pure C due to
653: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
654: in some cases (gcc/gfortran/libc/OS and arch conjonction);
655: - a memory leak is fixed in REMOVE intrinsic;

664: - --enable-profile flag is added to configure script. When this flag is
665: enabled, rpl is built with -pg option;
666: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
667: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
668: process is killed;
669: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
670: know typeof() intrinsic function. This function is not standard but exists
671: under Sun Studio, gcc, and maybe some others compilers. If this function does
672: not exist on your compiler, you can change its definition by old one in
673: src/rpl.h;

714: static variable that is shared by multiple threads;
715: - '->' intrinsic is improved. All object copies have been avoided;
716: - -n flag is added to catch HUP signal. stderr and stdout are redirected
717: to a file, stdin is redirected to /dev/null when control process is killed;

734: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
735: that all programs that worked with old SQL intrinsic can now work with
736: SQLQUERY. With all new programs, you can open a real connection to databases;
737: - NRPROC is added. This new intrinsic is used to catch error from child
738: process. Without NRPROC, any errors returned by child process cause
739: main process to abort;
740: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
741: starts a new process). There are no mutexes in RPL/2 because all spawned process
742: use specific context. Nevertheless, shared variables and associated mutexes
743: should be added;
744: - -D flag and DAEMONIZE intrinsic have been added;

1093: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1094: versions of PROTECT and UNPROTECT that only deal with global variables
1095: (see RCL/SAVE);
1096: - variable management routines have been rewritten. The new ones are
1097: uncompatible with the old ones. Before these changes, a local variable

1520: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1521: of known external functions but add the new list to the last. { "all" }
1522: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1523: external names of the known functions;
1524: - mkrplso.in is modified.
1525: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1526: - vim syntax file is upgraded;
1527: - a minor mistake is fixed in recherche_instruction_suivante();
1528: - some minor memory leaks are fixed in recherche_type() function. They only
1529: occurs when a syntax error is detected;
1530: - #error and #warning preprocessor macros are added;
1531: - INCR and DECR are written (with integer or variable argument);
1532: - CSWP and RSWP are added and tested;
1533: - a minor bug is fixed in analyse.c;
1534: - DEBIAN/control is added to build debian package;
1535: - SCALE is fixed and improved ("automatic" keyword);
1536: - PUTC and PUTR new intrinsics are added.
1537: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1538: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1539: VISIT does not find a name in level 1;
1540: - configure.in script is modified to add a new test (--enable-debug
1541: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1542: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1543: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1544: 'MATRIX' { 2 2 3 } GETR;
1545: - LOGSCALE intrinsic is improved and now, it can be used as
1546: { "main" "auxiliary" X Y } LOGSCALE;
1547: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1548: same than AXES:
1549: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1550: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1551: { { -10 10 } "automatic" } SCALE.
1552: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1553: because it changes only the dimension of the screen. To have a logarithmic
1554: scale, you must use LOGSCALE intrinsic:
1555: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1556: screen on second scale;
1557: - { X X } autoscale and { Y Y } logscale are now invalid;
1558: - *D is added (depth multiplication, for 3D graphics);
1559: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1560: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1561: - a major bug is fixed in GETI instrinsic when it is used with a name
1562: that contains a matrix or a vector (bad upper bounds conditions in
1563: incrementation);
1564: - DISP intrinsic now uses the 33-th flag. When it is not set
1565: (default), a final carriage return is sent to the terminal;
1566: - AXES intrinsic only takes a list that can contains the keywork
1567: "main" or "auxiliary". Before this modification, this keyword was in
1568: the first stack level;
1569: - vim syntax file is upgraded;
1570: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1571: option;
1572: - LAST is now disabled in the main loop of INT intrinsic;
1573: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1574: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1575: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1576: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1577: in 0);
1578: - LAST is disabled in the main loop of DRAW intrinsic;
1579: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1580: evaluation of an equation, the system stack is returned corrupted to the
1581: sequencer;
1582: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1583: of a loop are not integer or real.
1584: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1594: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1595: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1615: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1616: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1617: is a quick and dirty workaround...);
1618: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1619: - rplconvert is improved.
