48: adress is set to 0.0.0.0;
49: - new rule is added to main makefile (make debian) to build deb package;
50: - new benchmark (Xeon W3520 @ 2.67GHz) :

56: - recherche_type() did not convert huge integer in real. Now,
57: 18446744072742037448 is converted into real as value cannot be stored in
58: RPL/2 integer type;
59: - WFSOCK is modified to handle unconnected sockets;

63: a real copy. Now, struct_mutex contains locks owner. On Linux or Solaris (for
64: example), it is possible to lock mutex from a thread and unlock the same mutex
65: from another thread. On NetBSD, system crashes.

140: - major bug is fixed in READ intrinsic (socket). This bug was introduced
141: by a new feature in glibc.
142: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
143: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
144: "ALL" IMPLICIT when it runs in interactive mode;
145: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
146: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
147: to use SAVE to manipulate global variables;
148: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
149: subroutines;
150: - fix major memory access violation in evaluation subroutine. Only occurs
151: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
152: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
153: when X was a vector or a table.

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

203: parent process was not interrupted if it is not group master process. To fix
204: this bug, SIGINJECT signal is not sent by child process but by control thread
205: in parent process;
206: - minor bug is fixed in data injection (POKE) that does not work as expected
207: when child process is protected by NRPROC.
208: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
209: - --enable-sysv-sems is added to configure script to use SystemV semaphores
210: functions instead of POSIX functions. This function is disabled or forced on
211: systems that does not provide correct POSIX or SysV semaphores subsystem;
212: - a dirty but not quick patch is written to workaround broken siginfo
213: structures. This patch has been successfully tested. It uses a segment of
214: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
215: (Unix PID);
216: - some OpenBSD's hacks are added;
217: - broken siginfo->si_pid field is now checked by configure script;
218: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

227: - TOKENIZE is now able to convert escape sequences;
228: - ATPOKE and CLRATPOKE new intrinsics are added;
229: - --enable-full-static configure flag is added. With this flag, mysql and
230: postgresql libraries are statically linked in rpl executable;
231: - units Makefile is modified to avoid readline and ncurses usages;
232: - sqlite is upgraded to 3.7.0.1;
233: - units is upgraded to 1.88;
234: - another major bug is fixed in the same variable creation subroutine.
235: Level 0 and 1 variables adresses were swapped when a global variable masked
236: a name of RPL/2 routine;
237: - major bug is fixed in global variable creation subroutine. When a global
238: variable was created and when a local variable existed with the same name,
239: computed address of global variable was wrong;
240: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
241: is forced in front of all libraries.
242: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
243: - BACKTRACE intrinsic is added;
244: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
245: when this structure is included in IFERR/THEN/END structure and when an error is
246: caught;
247: - major bug is fixed in analyse() subroutine. When evaluation() returned error
248: in a compiled program, analyse() caught this error twice and randomly aborted
249: with a segmentation error;
250: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
251: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
252: signals;
253: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
254: matrix.
255: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
256: - minor bug is fixed in evaluation() subroutine. With this patch, same program
257: returns same result with or without -p flag;

261: - debug memory allocation subroutines are improved to run in multithreaded
262: programs;
263: - some memory leaks are fixed in process management (SPAWN and DETACH);
264: - version verification is added to shared objects;
265: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
266: linux (false mremap() prototype);
267: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
268: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
269: - all '-' are replaced by '_' in random generator list;

273: format in FCH (file descriptor) and SCK (socket descriptor);
274: - debug routines are improved;
275: - PROCID is added;
276: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
277: and to not use swap;
278: - major bug is fixed in sql support. SQL connections were closed in all chield
279: process;
280: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
281: discovered in Solaris thread safe allocators (libmalloc and libumem) that
282: are first fit class allocators. Solaris libmtmalloc works better and is
283: a best fit class allocator but its performance is poor than ptmalloc3
284: performance;
285: - major bug is fixed in ROW+ intrinsic (new row was not added where it
286: should);
287: - minor bugs are fixed in interruptions.c (semaphores values when error is
288: caught);
289: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
290: created by SPAWN;
291: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
292: ATEXIT. If it receives SIGFABORT, it does not;
293: - ONEXIT is renamed in ATEXIT;
294: - ONEXIT new intrinsic is added.

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

359: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
360: each execution (md5 and sha1 sums) to enhance security. If one of these tools
361: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
362: on a non recoverable system error;
363: - openssl and sqlite3 libraries are added;
364: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

392: Number of scalar operations per second and per core : 2383016
393:
394: - PULPRFL does not abort on BUG() but on execution error;
395: - TRIM, REPL and TOKENIZE are added;
396: - sockets options are now set before bind();
397: - shutdown() is added to all connected sockets;
398: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
399: list argument and inexistant elements).
400: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
401: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
402: signals sent to main process were not caught because DAEMON did not replace
403: old pid by new one;
404: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
405: evaluation when an error is reported from a subroutine in another subroutine.
406: For example, error was not caught in following program when it is executed with
407: -p option :
408: TEST << iferr TEST2 then end >>
409: TEST2 << 0 inv >>
410: - major bug is fixed in variable management. Some local variables were
411: seen as global ones;
412: - major bug is fixed in rplcore. Rplcore entered in dead lock when
413: script file contains a multibyte character;
414: - IN intrinsic is added;
415: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
416: returned false ;
417: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
418: programs;
419: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
420: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
421: strings were never closed;
422: - some bugs have been fixed in file management;
423: - RPL/2 can now be run on EBCDIC systems (OS/390);
424: - major bug is fixed in -A command line option (NULL character is missing);
425: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
426: made by blocks (1024 bytes). When an incomplete multibyte sequence is
427: encountered at end of block, subroutine aborts with an execution error;
428: - major bug is fixed in OPEN (TCP/IPv4 sockets).
429: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
430: - DISP now locks stdout;
431: - rpliconv is added to replace standard iconv provided by operating system.
432: Indeed, conversion between different encodages requires transliteration
433: that is not offered by some iconv utility;
434: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
435: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
436: not be found), SYSEVAL enters in a dead lock;
437: - fprintf is replaced by some functions that allow transliterations between
438: locales;
439: - '"' can now be used in strings ("\"");
440: - iconv is called with -c in preprocessor stage. It is done to write
441: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
442: - double free is fixed in liberation() (type SQL, only occurs when locale is
443: set);
444: - LOCALIZATION, UCASE and LCASE are added;
445: - major bug is fixed in EXIT intrinsic that was able to return a false
446: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
447: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
448: used in onLoading from shared library, USE was pushed on stack as algebraic
449: expression;
450: - libiconv is upgraded to 1.13.1;
451: - gnuplot is upgraded to 4.2.6;
452: - gsl is upgraded to 1.13.
453: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
454: - pipe() is overwritten by a macro to avoid a system error. Communication
455: between process are done with pipes and these pipes are managed by a
456: specific asynchrone thread. If a script try to create more threads than
457: management thread can destroy, you can quickly achieve maximum number of
458: opened files and pipe() shall return a system error. This macro tries to create
459: pipes. If pipe() function returns an error, macro waits and retries. If
460: number of retries is greater than a hardcoded value, macro returns an error;
461: - major bug (deadlock) is fixed in process and thread management. I hope
462: this bug shall be the last one;
463: - major bug is fixed in DET intrinsic (determinant was computed without LU
464: diagonalization);
465: - SWAPCNTXT is added;
466: - minor bug is fixed in Makefile.am (licences rule).
467: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
468: - some bugfixes are added in process management;
469: - all process management is rewritten to avoid usage of defunct process
470: or thread number;
471: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
472: was called before a pending interruption5 (SIGFSTOP), signal handler uses
473: a freed semaphore and corrupts heap;
474: - CLRERR is added to erase previous errors;
475: - ERRN and ERRM return exception message and number;
476: - major bug is fixed in interruptions.c. All signal are now bufferised
477: when semaphore_liste_threads is null to avoid deadlock. This bug only
478: occured when STOP was sent to a dying thread or process (when this thread or
479: process was running retrait_thread());
480: - matrix rank is computed before matrix inversion;
481: - file locks are added to stdin and stdout. stderr is not locked because
482: all messages written by signal handlers are sent to stderr;
483: - configure.in script is modified to test gcc version and avoid a bug in
484: gcc older than 4.4;
485: - some benchmarks have been done :

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

586: deadlock when a huge amount of threads is launched);
587: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
588: arguments types are unsupported;

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

624: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
625: that all programs that worked with old SQL intrinsic can now work with
626: SQLQUERY. With all new programs, you can open a real connection to databases;
627: - NRPROC is added. This new intrinsic is used to catch error from child
628: process. Without NRPROC, any errors returned by child process cause
629: main process to abort;
630: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
631: starts a new process). There are no mutexes in RPL/2 because all spawned process
632: use specific context. Nevertheless, shared variables and associated mutexes
633: should be added;

720: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
721: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
722: workaround for this major bug. Nevertheless, all others capabilities seems to
723: work fine;

771: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
772: before starting interrupt evaluation;
773: - -f parameter is added when iconv is called;
774: - as old file program was bugged, a new option is added to configure script.
775: When configure is called with --disable-encoding-autodetection, make does not
776: try to detect source encoding. Please, do not use if RPL/2 can be built
777: without this option !
778: - new garbage collector (and more efficient) is written;
779: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does

981: With STATIC, next variables created by '->' are static;
982: - PROTECT and UNPROTECT are added to protect variables against write
983: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
984: versions of PROTECT and UNPROTECT that only deal with global variables
985: (see RCL/SAVE);
986: - variable management routines have been rewritten. The new ones are
987: uncompatible with the old ones. Before these changes, a local variable
988: was exported to a child subroutine, but cannot be modified into this

1311: fine...);
1312: - NOT is not correctly formatted in formateur.c:
1313: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1314: with a NOTZ function !
1315: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1318: - RPL/2 is tested with efence and valgrind;
1319: - configure.in script is modified;
1320: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1321: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1381: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1382: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1383: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1400: - SCLS is added;
1401: - DRWS now uses COLS to draw 2D graphics;
1402: - PPAR and SPAR are written. SPAR returns a list that contains the
1403: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1404: statistical variable, or "DISABLED" if its type is not one of the type of
1405: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1406: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1407: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1408: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1409: disabled. Arguments of EXTERNAL are case sensitive because the external
1410: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1411: of known external functions but add the new list to the last. { "all" }
1412: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1413: external names of the known functions;
1414: - mkrplso.in is modified.
1415: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1416: - vim syntax file is upgraded;
1417: - a minor mistake is fixed in recherche_instruction_suivante();
1418: - some minor memory leaks are fixed in recherche_type() function. They only

1428: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1429: VISIT does not find a name in level 1;
1430: - configure.in script is modified to add a new test (--enable-debug
1431: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1432: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1433: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1434: 'MATRIX' { 2 2 3 } GETR;
1435: - LOGSCALE intrinsic is improved and now, it can be used as
1436: { "main" "auxiliary" X Y } LOGSCALE;
1437: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1438: same than AXES:
1439: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1440: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1441: { { -10 10 } "automatic" } SCALE.
1442: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1443: because it changes only the dimension of the screen. To have a logarithmic
1444: scale, you must use LOGSCALE intrinsic:
1445: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1446: screen on second scale;
1447: - { X X } autoscale and { Y Y } logscale are now invalid;
1448: - *D is added (depth multiplication, for 3D graphics);
1449: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1450: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1451: - a major bug is fixed in GETI instrinsic when it is used with a name
1452: that contains a matrix or a vector (bad upper bounds conditions in
1453: incrementation);
1454: - DISP intrinsic now uses the 33-th flag. When it is not set
1455: (default), a final carriage return is sent to the terminal;
1456: - AXES intrinsic only takes a list that can contains the keywork
1457: "main" or "auxiliary". Before this modification, this keyword was in
1458: the first stack level;
1459: - vim syntax file is upgraded;
1460: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1461: option;
1462: - LAST is now disabled in the main loop of INT intrinsic;
1463: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1464: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1465: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1466: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1467: in 0);
1468: - LAST is disabled in the main loop of DRAW intrinsic;
1469: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1470: evaluation of an equation, the system stack is returned corrupted to the
1471: sequencer;
1472: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1473: of a loop are not integer or real.
1474: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1475: - the compilation stage aborts with an error message when two definitions
1476: have the same name. To improve the compilation() subroutine, I have to
1477: add some tests in gestion_variables.c;
1478: - recherche_type() subroutine ad some other connex subroutines are improved.
1479: Now, some syntax errors about object are caught and do not perform sequencer
1480: hangup;
1481: - readline is upgraded (minor compilation bug with recent gcc);
1482: - Makefile.am's and configure.in scripts are improved.
1483: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1484: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1485: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1486: the boxwidth, 1 by default);
1487: - recherche_type() is rewritten to be faster;
1488: - gsl is upgraded (release 1.3);
1489: - ncurses is upgraded and patched (release 5.3);
1490: - recherche_instruction_suivante() is fixed (string research with included
1491: '"') and rewritten to be faster;
1492: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1493: segfault.
1494: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1502: - a minor bug is fixed in evaluation subroutine;
1503: - vim syntax file is improved;
1504: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1505: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1506: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1507: is a quick and dirty workaround...);
