170: by a new feature in glibc.
171: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
172: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
173: "ALL" IMPLICIT when it runs in interactive mode;
174: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
175: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
176: to use SAVE to manipulate global variables;
177: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
178: subroutines;
179: - fix major memory access violation in evaluation subroutine. Only occurs
180: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
181: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
182: when X was a vector or a table.
183: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

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

232: parent process was not interrupted if it is not group master process. To fix
233: this bug, SIGINJECT signal is not sent by child process but by control thread
234: in parent process;
235: - minor bug is fixed in data injection (POKE) that does not work as expected
236: when child process is protected by NRPROC.
237: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
238: - --enable-sysv-sems is added to configure script to use SystemV semaphores
239: functions instead of POSIX functions. This function is disabled or forced on
240: systems that does not provide correct POSIX or SysV semaphores subsystem;
241: - a dirty but not quick patch is written to workaround broken siginfo
242: structures. This patch has been successfully tested. It uses a segment of
243: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
244: (Unix PID);
245: - some OpenBSD's hacks are added;
246: - broken siginfo->si_pid field is now checked by configure script;
247: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

256: - TOKENIZE is now able to convert escape sequences;
257: - ATPOKE and CLRATPOKE new intrinsics are added;
258: - --enable-full-static configure flag is added. With this flag, mysql and
259: postgresql libraries are statically linked in rpl executable;

264: Level 0 and 1 variables adresses were swapped when a global variable masked
265: a name of RPL/2 routine;
266: - major bug is fixed in global variable creation subroutine. When a global
267: variable was created and when a local variable existed with the same name,
268: computed address of global variable was wrong;
269: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
270: is forced in front of all libraries.
271: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
272: - BACKTRACE intrinsic is added;
273: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
274: when this structure is included in IFERR/THEN/END structure and when an error is
275: caught;
276: - major bug is fixed in analyse() subroutine. When evaluation() returned error
277: in a compiled program, analyse() caught this error twice and randomly aborted
278: with a segmentation error;
279: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
280: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
281: signals;
282: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
283: matrix.
284: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

291: programs;
292: - some memory leaks are fixed in process management (SPAWN and DETACH);
293: - version verification is added to shared objects;
294: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
295: linux (false mremap() prototype);
296: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.

302: format in FCH (file descriptor) and SCK (socket descriptor);
303: - debug routines are improved;
304: - PROCID is added;
305: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
306: and to not use swap;
307: - major bug is fixed in sql support. SQL connections were closed in all chield
308: process;
309: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
310: discovered in Solaris thread safe allocators (libmalloc and libumem) that
311: are first fit class allocators. Solaris libmtmalloc works better and is
312: a best fit class allocator but its performance is poor than ptmalloc3
313: performance;
314: - major bug is fixed in ROW+ intrinsic (new row was not added where it
315: should);
316: - minor bugs are fixed in interruptions.c (semaphores values when error is
317: caught);
318: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
319: created by SPAWN;

329: information about shared variable was not copied to new processus structure;
330: - some little memory leaks are fixed in evaluation(), recherche_type() and
331: sequenceur(). They only occured when syntax error were caught;
332: - IMPLICIT causes execution error instead system error;
333: - Hurd support is improved but currently broken because Hurd does not support
334: SIG_INFO. Work in progress;
335: - OpenBSD specific support is removed from sources;
336: - support for Mac OS X and Windows/Cygwin is added.

390: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
391: on a non recoverable system error;
392: - openssl and sqlite3 libraries are added;
393: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
394: variable indicates RPL/2 root directory. If it is not set, root path
395: is given by configure script (d_exec_path);
396: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
397: - configure.in and makefile.am's are modified to add Cygwin support. Interix

404: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
405: - Makefile.am are modified to authorize parallel builds;
406: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
407: and writes warning to standard output;
408: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)
409: - escape codes are now converted in formateur(), not in recherche_type() to
410: avoid a minor bug in EDIT and VISIT intrinsics;

412: - file-5.03 is patched to avoid bus error on systems that require memory
413: alignment;
414: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
415: were able to be avoided by evaluation routine.

424: - TRIM, REPL and TOKENIZE are added;
425: - sockets options are now set before bind();
426: - shutdown() is added to all connected sockets;
427: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
428: list argument and inexistant elements).
429: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
430: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
431: signals sent to main process were not caught because DAEMON did not replace
432: old pid by new one;
433: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
434: evaluation when an error is reported from a subroutine in another subroutine.
435: For example, error was not caught in following program when it is executed with
436: -p option :
437: TEST << iferr TEST2 then end >>
438: TEST2 << 0 inv >>
439: - major bug is fixed in variable management. Some local variables were
440: seen as global ones;
441: - major bug is fixed in rplcore. Rplcore entered in dead lock when
442: script file contains a multibyte character;
443: - IN intrinsic is added;
444: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
445: returned false ;
446: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
447: programs;
448: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
449: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
450: strings were never closed;
451: - some bugs have been fixed in file management;
452: - RPL/2 can now be run on EBCDIC systems (OS/390);
453: - major bug is fixed in -A command line option (NULL character is missing);
454: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
455: made by blocks (1024 bytes). When an incomplete multibyte sequence is
456: encountered at end of block, subroutine aborts with an execution error;
457: - major bug is fixed in OPEN (TCP/IPv4 sockets).
458: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
459: - DISP now locks stdout;
460: - rpliconv is added to replace standard iconv provided by operating system.
461: Indeed, conversion between different encodages requires transliteration
462: that is not offered by some iconv utility;
463: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
464: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
465: not be found), SYSEVAL enters in a dead lock;
466: - fprintf is replaced by some functions that allow transliterations between
467: locales;
468: - '"' can now be used in strings ("\"");
469: - iconv is called with -c in preprocessor stage. It is done to write
470: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
471: - double free is fixed in liberation() (type SQL, only occurs when locale is
472: set);
473: - LOCALIZATION, UCASE and LCASE are added;
474: - major bug is fixed in EXIT intrinsic that was able to return a false
475: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
476: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
477: used in onLoading from shared library, USE was pushed on stack as algebraic
478: expression;
479: - libiconv is upgraded to 1.13.1;
480: - gnuplot is upgraded to 4.2.6;
481: - gsl is upgraded to 1.13.
482: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
483: - pipe() is overwritten by a macro to avoid a system error. Communication
484: between process are done with pipes and these pipes are managed by a
485: specific asynchrone thread. If a script try to create more threads than
486: management thread can destroy, you can quickly achieve maximum number of
487: opened files and pipe() shall return a system error. This macro tries to create
488: pipes. If pipe() function returns an error, macro waits and retries. If
489: number of retries is greater than a hardcoded value, macro returns an error;
490: - major bug (deadlock) is fixed in process and thread management. I hope
491: this bug shall be the last one;
492: - major bug is fixed in DET intrinsic (determinant was computed without LU
493: diagonalization);
494: - SWAPCNTXT is added;
495: - minor bug is fixed in Makefile.am (licences rule).
496: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
497: - some bugfixes are added in process management;
498: - all process management is rewritten to avoid usage of defunct process
499: or thread number;
500: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
501: was called before a pending interruption5 (SIGFSTOP), signal handler uses
502: a freed semaphore and corrupts heap;
503: - CLRERR is added to erase previous errors;
504: - ERRN and ERRM return exception message and number;
505: - major bug is fixed in interruptions.c. All signal are now bufferised
506: when semaphore_liste_threads is null to avoid deadlock. This bug only
507: occured when STOP was sent to a dying thread or process (when this thread or
508: process was running retrait_thread());
509: - matrix rank is computed before matrix inversion;
510: - file locks are added to stdin and stdout. stderr is not locked because
511: all messages written by signal handlers are sent to stderr;
512: - configure.in script is modified to test gcc version and avoid a bug in
513: gcc older than 4.4;
514: - some benchmarks have been done :

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

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

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

655: SQLQUERY. With all new programs, you can open a real connection to databases;
656: - NRPROC is added. This new intrinsic is used to catch error from child
657: process. Without NRPROC, any errors returned by child process cause
658: main process to abort;
659: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
660: starts a new process). There are no mutexes in RPL/2 because all spawned process
661: use specific context. Nevertheless, shared variables and associated mutexes
662: should be added;

1010: With STATIC, next variables created by '->' are static;
1011: - PROTECT and UNPROTECT are added to protect variables against write
1012: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1013: versions of PROTECT and UNPROTECT that only deal with global variables
1014: (see RCL/SAVE);
1015: - variable management routines have been rewritten. The new ones are
1016: uncompatible with the old ones. Before these changes, a local variable
1017: was exported to a child subroutine, but cannot be modified into this
1018: child subroutine. Now, a local variable is accessible only in its subroutine;
1019: - SAVE intrinsic is added to manipulate global variables;

1340: fine...);
1341: - NOT is not correctly formatted in formateur.c:
1342: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1343: with a NOTZ function !
1344: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1347: - RPL/2 is tested with efence and valgrind;
1348: - configure.in script is modified;
1349: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1410: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1411: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1412: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1429: - SCLS is added;
1430: - DRWS now uses COLS to draw 2D graphics;
1431: - PPAR and SPAR are written. SPAR returns a list that contains the
1432: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1433: statistical variable, or "DISABLED" if its type is not one of the type of
1434: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1435: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1436: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1437: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1438: disabled. Arguments of EXTERNAL are case sensitive because the external
1439: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1440: of known external functions but add the new list to the last. { "all" }
1441: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1442: external names of the known functions;
1443: - mkrplso.in is modified.
1444: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1445: - vim syntax file is upgraded;
1446: - a minor mistake is fixed in recherche_instruction_suivante();

1457: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1458: VISIT does not find a name in level 1;
1459: - configure.in script is modified to add a new test (--enable-debug
1460: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1461: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1462: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1463: 'MATRIX' { 2 2 3 } GETR;
1464: - LOGSCALE intrinsic is improved and now, it can be used as
1465: { "main" "auxiliary" X Y } LOGSCALE;
1466: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1467: same than AXES:
1468: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1469: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1470: { { -10 10 } "automatic" } SCALE.
1471: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1472: because it changes only the dimension of the screen. To have a logarithmic
1473: scale, you must use LOGSCALE intrinsic:
1474: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1475: screen on second scale;
1476: - { X X } autoscale and { Y Y } logscale are now invalid;
1477: - *D is added (depth multiplication, for 3D graphics);
1478: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1479: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1480: - a major bug is fixed in GETI instrinsic when it is used with a name
1481: that contains a matrix or a vector (bad upper bounds conditions in
1482: incrementation);
1483: - DISP intrinsic now uses the 33-th flag. When it is not set
1484: (default), a final carriage return is sent to the terminal;
1485: - AXES intrinsic only takes a list that can contains the keywork
1486: "main" or "auxiliary". Before this modification, this keyword was in
1487: the first stack level;
1488: - vim syntax file is upgraded;
1489: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1490: option;
1491: - LAST is now disabled in the main loop of INT intrinsic;
1492: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1493: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1494: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1495: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1496: in 0);
1497: - LAST is disabled in the main loop of DRAW intrinsic;
1498: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1499: evaluation of an equation, the system stack is returned corrupted to the
1500: sequencer;
1501: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1502: of a loop are not integer or real.
1503: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1504: - the compilation stage aborts with an error message when two definitions
1505: have the same name. To improve the compilation() subroutine, I have to
1506: add some tests in gestion_variables.c;
1507: - recherche_type() subroutine ad some other connex subroutines are improved.
1508: Now, some syntax errors about object are caught and do not perform sequencer
1509: hangup;
