268: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
269: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
270: "ALL" IMPLICIT when it runs in interactive mode;
271: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
272: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
273: to use SAVE to manipulate global variables;
274: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
275: subroutines;
276: - fix major memory access violation in evaluation subroutine. Only occurs
277: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
278: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
279: when X was a vector or a table.

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

329: parent process was not interrupted if it is not group master process. To fix
330: this bug, SIGINJECT signal is not sent by child process but by control thread
331: in parent process;
332: - minor bug is fixed in data injection (POKE) that does not work as expected
333: when child process is protected by NRPROC.
334: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
335: - --enable-sysv-sems is added to configure script to use SystemV semaphores
336: functions instead of POSIX functions. This function is disabled or forced on
337: systems that does not provide correct POSIX or SysV semaphores subsystem;
338: - a dirty but not quick patch is written to workaround broken siginfo
339: structures. This patch has been successfully tested. It uses a segment of
340: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
341: (Unix PID);
342: - some OpenBSD's hacks are added;
343: - broken siginfo->si_pid field is now checked by configure script;
344: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

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

369: - BACKTRACE intrinsic is added;
370: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
371: when this structure is included in IFERR/THEN/END structure and when an error is
372: caught;
373: - major bug is fixed in analyse() subroutine. When evaluation() returned error
374: in a compiled program, analyse() caught this error twice and randomly aborted
375: with a segmentation error;
376: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
377: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
378: signals;
379: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty

382: - minor bug is fixed in evaluation() subroutine. With this patch, same program
383: returns same result with or without -p flag;
384: - ncurses 5.7 is upgraded to 20100619;
385: - openssl is upgraded to 1.0.0a;
386: - interrupt stacks are now FIFO instead of LIFO;
387: - debug memory allocation subroutines are improved to run in multithreaded
388: programs;
389: - some memory leaks are fixed in process management (SPAWN and DETACH);
390: - version verification is added to shared objects;
391: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
392: linux (false mremap() prototype);
393: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
394: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
395: - all '-' are replaced by '_' in random generator list;

400: - debug routines are improved;
401: - PROCID is added;
402: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
403: and to not use swap;
404: - major bug is fixed in sql support. SQL connections were closed in all chield
405: process;
406: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
407: discovered in Solaris thread safe allocators (libmalloc and libumem) that
408: are first fit class allocators. Solaris libmtmalloc works better and is
409: a best fit class allocator but its performance is poor than ptmalloc3
410: performance;
411: - major bug is fixed in ROW+ intrinsic (new row was not added where it
412: should);
413: - minor bugs are fixed in interruptions.c (semaphores values when error is
414: caught);
415: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
416: created by SPAWN;
417: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
418: ATEXIT. If it receives SIGFABORT, it does not;
419: - ONEXIT is renamed in ATEXIT;
420: - ONEXIT new intrinsic is added.
421: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)

425: - major bug is fixed in copie_etat_processus(). A field that contains
426: information about shared variable was not copied to new processus structure;
427: - some little memory leaks are fixed in evaluation(), recherche_type() and
428: sequenceur(). They only occured when syntax error were caught;
429: - IMPLICIT causes execution error instead system error;
430: - Hurd support is improved but currently broken because Hurd does not support
431: SIG_INFO. Work in progress;
432: - OpenBSD specific support is removed from sources;
433: - support for Mac OS X and Windows/Cygwin is added.
434: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

473: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
474: - in formatted file, string format returned a variable length string even if
475: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
476: a variable length string and 'CHARACTER*(n)' a fixed length string;
477: - keyed access files support is added. Currently, only formatted files are
478: supported;
479: - direct access files support is added. Currenlty, these files can only be used
480: in formatted mode;

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

527: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
528: signals sent to main process were not caught because DAEMON did not replace
529: old pid by new one;
530: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
531: evaluation when an error is reported from a subroutine in another subroutine.
532: For example, error was not caught in following program when it is executed with
533: -p option :
534: TEST << iferr TEST2 then end >>
535: TEST2 << 0 inv >>
536: - major bug is fixed in variable management. Some local variables were
537: seen as global ones;

539: script file contains a multibyte character;
540: - IN intrinsic is added;
541: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
542: returned false ;
543: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
544: programs;
545: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
546: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

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

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

569: set);
570: - LOCALIZATION, UCASE and LCASE are added;

580: - pipe() is overwritten by a macro to avoid a system error. Communication
581: between process are done with pipes and these pipes are managed by a
582: specific asynchrone thread. If a script try to create more threads than
583: management thread can destroy, you can quickly achieve maximum number of
584: opened files and pipe() shall return a system error. This macro tries to create
585: pipes. If pipe() function returns an error, macro waits and retries. If
586: number of retries is greater than a hardcoded value, macro returns an error;
587: - major bug (deadlock) is fixed in process and thread management. I hope
588: this bug shall be the last one;
589: - major bug is fixed in DET intrinsic (determinant was computed without LU

599: a freed semaphore and corrupts heap;
600: - CLRERR is added to erase previous errors;
601: - ERRN and ERRM return exception message and number;
602: - major bug is fixed in interruptions.c. All signal are now bufferised
603: when semaphore_liste_threads is null to avoid deadlock. This bug only
604: occured when STOP was sent to a dying thread or process (when this thread or
605: process was running retrait_thread());
606: - matrix rank is computed before matrix inversion;
607: - file locks are added to stdin and stdout. stderr is not locked because
608: all messages written by signal handlers are sent to stderr;

683: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
684: process is killed;
685: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
686: know typeof() intrinsic function. This function is not standard but exists
687: under Sun Studio, gcc, and maybe some others compilers. If this function does
688: not exist on your compiler, you can change its definition by old one in

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

750: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
751: that all programs that worked with old SQL intrinsic can now work with
752: SQLQUERY. With all new programs, you can open a real connection to databases;
753: - NRPROC is added. This new intrinsic is used to catch error from child
754: process. Without NRPROC, any errors returned by child process cause
755: main process to abort;
756: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
757: starts a new process). There are no mutexes in RPL/2 because all spawned process
758: use specific context. Nevertheless, shared variables and associated mutexes
759: should be added;
760: - -D flag and DAEMONIZE intrinsic have been added;

1109: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1110: versions of PROTECT and UNPROTECT that only deal with global variables
1111: (see RCL/SAVE);
1112: - variable management routines have been rewritten. The new ones are
1113: uncompatible with the old ones. Before these changes, a local variable

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

1610: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1611: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1613: - recherche_type() is rewritten to be faster;
1614: - gsl is upgraded (release 1.3);
1615: - ncurses is upgraded and patched (release 5.3);
1616: - recherche_instruction_suivante() is fixed (string research with included
1617: '"') and rewritten to be faster;

1628: - a minor bug is fixed in evaluation subroutine;
1629: - vim syntax file is improved;
1630: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1631: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1632: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1633: is a quick and dirty workaround...);
1634: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1635: - rplconvert is improved.
