156: by a new feature in glibc.
157: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
158: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
159: "ALL" IMPLICIT when it runs in interactive mode;
160: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
161: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
162: to use SAVE to manipulate global variables;
163: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
164: subroutines;
165: - fix major memory access violation in evaluation subroutine. Only occurs
166: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
167: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
168: when X was a vector or a table.

198: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
199: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
200: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
201: corruption. As internal memory management have been improved, a best fit
202: allocator like ptmalloc3 is not required anymore;
203: - gnuplot is upgraded to 4.4.1;
204: - deadlock is fixed in signal handlers: same mutex was used in standard
205: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
206: and signal handlers. A new signal handler specific mutex is added;
207: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
208: that has to be evaluated by ->NUM;
209: - rplfile build process is modify to be sure that rplfile is not modified
210: after rpl build stage (to be sure that rplfile checksum is not modified after

215: ABORT now works on eComStation;
216: - sqlite is upgraded to 3.7.2;
217: - bug is fixed in software interrupts. When both process have different PID,
218: parent process was not interrupted if it is not group master process. To fix
219: this bug, SIGINJECT signal is not sent by child process but by control thread
220: in parent process;
221: - minor bug is fixed in data injection (POKE) that does not work as expected
222: when child process is protected by NRPROC.
223: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
224: - --enable-sysv-sems is added to configure script to use SystemV semaphores
225: functions instead of POSIX functions. This function is disabled or forced on
226: systems that does not provide correct POSIX or SysV semaphores subsystem;
227: - a dirty but not quick patch is written to workaround broken siginfo
228: structures. This patch has been successfully tested. It uses a segment of
229: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
230: (Unix PID);
231: - some OpenBSD's hacks are added;
232: - broken siginfo->si_pid field is now checked by configure script;
233: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

241: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
242: - TOKENIZE is now able to convert escape sequences;
243: - ATPOKE and CLRATPOKE new intrinsics are added;
244: - --enable-full-static configure flag is added. With this flag, mysql and
245: postgresql libraries are statically linked in rpl executable;

247: - sqlite is upgraded to 3.7.0.1;
248: - units is upgraded to 1.88;
249: - another major bug is fixed in the same variable creation subroutine.
250: Level 0 and 1 variables adresses were swapped when a global variable masked
251: a name of RPL/2 routine;
252: - major bug is fixed in global variable creation subroutine. When a global
253: variable was created and when a local variable existed with the same name,
254: computed address of global variable was wrong;
255: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
256: is forced in front of all libraries.
257: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
258: - BACKTRACE intrinsic is added;
259: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
260: when this structure is included in IFERR/THEN/END structure and when an error is
261: caught;
262: - major bug is fixed in analyse() subroutine. When evaluation() returned error
263: in a compiled program, analyse() caught this error twice and randomly aborted
264: with a segmentation error;
265: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
266: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
267: signals;
268: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
269: matrix.
270: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
271: - minor bug is fixed in evaluation() subroutine. With this patch, same program
272: returns same result with or without -p flag;

274: - openssl is upgraded to 1.0.0a;
275: - interrupt stacks are now FIFO instead of LIFO;
276: - debug memory allocation subroutines are improved to run in multithreaded
277: programs;
278: - some memory leaks are fixed in process management (SPAWN and DETACH);
279: - version verification is added to shared objects;
280: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
281: linux (false mremap() prototype);
282: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
283: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
284: - all '-' are replaced by '_' in random generator list;

288: format in FCH (file descriptor) and SCK (socket descriptor);
289: - debug routines are improved;
290: - PROCID is added;
291: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
292: and to not use swap;
293: - major bug is fixed in sql support. SQL connections were closed in all chield
294: process;
295: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
296: discovered in Solaris thread safe allocators (libmalloc and libumem) that
297: are first fit class allocators. Solaris libmtmalloc works better and is
298: a best fit class allocator but its performance is poor than ptmalloc3
299: performance;
300: - major bug is fixed in ROW+ intrinsic (new row was not added where it
301: should);
302: - minor bugs are fixed in interruptions.c (semaphores values when error is
303: caught);
304: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
305: created by SPAWN;
306: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute

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

410: - TRIM, REPL and TOKENIZE are added;
411: - sockets options are now set before bind();
412: - shutdown() is added to all connected sockets;
413: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with

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

572: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
573: process is killed;
574: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
575: know typeof() intrinsic function. This function is not standard but exists
576: under Sun Studio, gcc, and maybe some others compilers. If this function does

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

641: SQLQUERY. With all new programs, you can open a real connection to databases;
642: - NRPROC is added. This new intrinsic is used to catch error from child
643: process. Without NRPROC, any errors returned by child process cause
644: main process to abort;
645: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
646: starts a new process). There are no mutexes in RPL/2 because all spawned process
647: use specific context. Nevertheless, shared variables and associated mutexes

996: With STATIC, next variables created by '->' are static;
997: - PROTECT and UNPROTECT are added to protect variables against write
998: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
999: versions of PROTECT and UNPROTECT that only deal with global variables
1000: (see RCL/SAVE);
1001: - variable management routines have been rewritten. The new ones are
1002: uncompatible with the old ones. Before these changes, a local variable
1003: was exported to a child subroutine, but cannot be modified into this
1004: child subroutine. Now, a local variable is accessible only in its subroutine;
1005: - SAVE intrinsic is added to manipulate global variables;

1326: fine...);
1327: - NOT is not correctly formatted in formateur.c:
1328: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1329: with a NOTZ function !
1330: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1333: - RPL/2 is tested with efence and valgrind;
1334: - configure.in script is modified;
1335: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1396: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1397: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1398: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1415: - SCLS is added;
1416: - DRWS now uses COLS to draw 2D graphics;
1417: - PPAR and SPAR are written. SPAR returns a list that contains the
1418: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1419: statistical variable, or "DISABLED" if its type is not one of the type of
1420: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1421: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1422: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1423: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1424: disabled. Arguments of EXTERNAL are case sensitive because the external
1425: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1426: of known external functions but add the new list to the last. { "all" }
1427: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1428: external names of the known functions;
1429: - mkrplso.in is modified.
1430: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1431: - vim syntax file is upgraded;
1432: - a minor mistake is fixed in recherche_instruction_suivante();

1443: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1444: VISIT does not find a name in level 1;
1445: - configure.in script is modified to add a new test (--enable-debug
1446: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1447: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1448: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1449: 'MATRIX' { 2 2 3 } GETR;
1450: - LOGSCALE intrinsic is improved and now, it can be used as
1451: { "main" "auxiliary" X Y } LOGSCALE;
1452: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1453: same than AXES:
1454: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1455: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1456: { { -10 10 } "automatic" } SCALE.
1457: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1458: because it changes only the dimension of the screen. To have a logarithmic
1459: scale, you must use LOGSCALE intrinsic:
1460: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1461: screen on second scale;
1462: - { X X } autoscale and { Y Y } logscale are now invalid;
1463: - *D is added (depth multiplication, for 3D graphics);
1464: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1465: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1466: - a major bug is fixed in GETI instrinsic when it is used with a name
1467: that contains a matrix or a vector (bad upper bounds conditions in
1468: incrementation);
1469: - DISP intrinsic now uses the 33-th flag. When it is not set
1470: (default), a final carriage return is sent to the terminal;
1471: - AXES intrinsic only takes a list that can contains the keywork
1472: "main" or "auxiliary". Before this modification, this keyword was in
1473: the first stack level;
1474: - vim syntax file is upgraded;
1475: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1476: option;
1477: - LAST is now disabled in the main loop of INT intrinsic;
1478: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1479: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1480: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1481: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1482: in 0);
1483: - LAST is disabled in the main loop of DRAW intrinsic;
1484: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1485: evaluation of an equation, the system stack is returned corrupted to the
1486: sequencer;
1487: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1488: of a loop are not integer or real.
1489: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1490: - the compilation stage aborts with an error message when two definitions
1491: have the same name. To improve the compilation() subroutine, I have to
1492: add some tests in gestion_variables.c;
1493: - recherche_type() subroutine ad some other connex subroutines are improved.
1494: Now, some syntax errors about object are caught and do not perform sequencer
1495: hangup;
1496: - readline is upgraded (minor compilation bug with recent gcc);
1497: - Makefile.am's and configure.in scripts are improved.
1498: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1499: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1500: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1501: the boxwidth, 1 by default);
1502: - recherche_type() is rewritten to be faster;
1503: - gsl is upgraded (release 1.3);
1504: - ncurses is upgraded and patched (release 5.3);
1505: - recherche_instruction_suivante() is fixed (string research with included
1506: '"') and rewritten to be faster;
