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

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

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

229: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
230: - TOKENIZE is now able to convert escape sequences;
231: - ATPOKE and CLRATPOKE new intrinsics are added;
232: - --enable-full-static configure flag is added. With this flag, mysql and
233: postgresql libraries are statically linked in rpl executable;
234: - units Makefile is modified to avoid readline and ncurses usages;
235: - sqlite is upgraded to 3.7.0.1;
236: - units is upgraded to 1.88;
237: - another major bug is fixed in the same variable creation subroutine.
238: Level 0 and 1 variables adresses were swapped when a global variable masked
239: a name of RPL/2 routine;
240: - major bug is fixed in global variable creation subroutine. When a global
241: variable was created and when a local variable existed with the same name,
242: computed address of global variable was wrong;
243: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
244: is forced in front of all libraries.
245: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
246: - BACKTRACE intrinsic is added;
247: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
248: when this structure is included in IFERR/THEN/END structure and when an error is
249: caught;
250: - major bug is fixed in analyse() subroutine. When evaluation() returned error
251: in a compiled program, analyse() caught this error twice and randomly aborted
252: with a segmentation error;
253: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
254: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
255: signals;
256: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
257: matrix.
258: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
259: - minor bug is fixed in evaluation() subroutine. With this patch, same program
260: returns same result with or without -p flag;

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

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

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

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

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

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

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

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

775: before starting interrupt evaluation;
776: - -f parameter is added when iconv is called;
777: - as old file program was bugged, a new option is added to configure script.
778: When configure is called with --disable-encoding-autodetection, make does not
779: try to detect source encoding. Please, do not use if RPL/2 can be built
780: without this option !
781: - new garbage collector (and more efficient) is written;

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

1314: fine...);
1315: - NOT is not correctly formatted in formateur.c:
1316: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1317: with a NOTZ function !
1318: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1321: - RPL/2 is tested with efence and valgrind;
1322: - configure.in script is modified;
1323: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1324: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1384: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1385: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1386: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1387: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1403: - SCLS is added;
1404: - DRWS now uses COLS to draw 2D graphics;
1405: - PPAR and SPAR are written. SPAR returns a list that contains the
1406: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1407: statistical variable, or "DISABLED" if its type is not one of the type of
1408: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1409: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1410: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1411: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1412: disabled. Arguments of EXTERNAL are case sensitive because the external
1413: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1414: of known external functions but add the new list to the last. { "all" }
1415: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1416: external names of the known functions;
1417: - mkrplso.in is modified.
1418: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1419: - vim syntax file is upgraded;
1420: - a minor mistake is fixed in recherche_instruction_suivante();
1421: - some minor memory leaks are fixed in recherche_type() function. They only

1430: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1431: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1432: VISIT does not find a name in level 1;
1433: - configure.in script is modified to add a new test (--enable-debug
1434: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1435: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1436: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1437: 'MATRIX' { 2 2 3 } GETR;
1438: - LOGSCALE intrinsic is improved and now, it can be used as
1439: { "main" "auxiliary" X Y } LOGSCALE;
1440: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1441: same than AXES:
1442: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1443: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1444: { { -10 10 } "automatic" } SCALE.
1445: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1446: because it changes only the dimension of the screen. To have a logarithmic
1447: scale, you must use LOGSCALE intrinsic:
1448: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1449: screen on second scale;
1450: - { X X } autoscale and { Y Y } logscale are now invalid;
1451: - *D is added (depth multiplication, for 3D graphics);
1452: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1453: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1454: - a major bug is fixed in GETI instrinsic when it is used with a name
1455: that contains a matrix or a vector (bad upper bounds conditions in
1456: incrementation);
1457: - DISP intrinsic now uses the 33-th flag. When it is not set
1458: (default), a final carriage return is sent to the terminal;
1459: - AXES intrinsic only takes a list that can contains the keywork
1460: "main" or "auxiliary". Before this modification, this keyword was in
1461: the first stack level;
1462: - vim syntax file is upgraded;
1463: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1464: option;
1465: - LAST is now disabled in the main loop of INT intrinsic;
1466: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1467: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1468: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1469: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1470: in 0);
1471: - LAST is disabled in the main loop of DRAW intrinsic;
1472: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1473: evaluation of an equation, the system stack is returned corrupted to the
1474: sequencer;
1475: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1476: of a loop are not integer or real.
1477: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1478: - the compilation stage aborts with an error message when two definitions
1479: have the same name. To improve the compilation() subroutine, I have to
1480: add some tests in gestion_variables.c;
1481: - recherche_type() subroutine ad some other connex subroutines are improved.
1482: Now, some syntax errors about object are caught and do not perform sequencer
1483: hangup;
1484: - readline is upgraded (minor compilation bug with recent gcc);
1485: - Makefile.am's and configure.in scripts are improved.
1486: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1487: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1488: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1489: the boxwidth, 1 by default);
1490: - recherche_type() is rewritten to be faster;
1491: - gsl is upgraded (release 1.3);
1492: - ncurses is upgraded and patched (release 5.3);
1493: - recherche_instruction_suivante() is fixed (string research with included
1494: '"') and rewritten to be faster;
1495: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1496: segfault.
1497: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)
1498: - RPL/2 is compiled by gcc-3.2.2 and seems to work;
1499: - the same minor bug is fixed in REDRAW and DRAX functions;
1500: - a minor fix is written in DRAW function (2D and 3D);
1501: - AXES intrinsic is improved. Now { { pi "ticsonly" 4 } "automatic" } DRAX
1502: is accepted;
1503: - a minor bug is fixed in VISIT intrinsic.
1504: * Sun Jan 26 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6b (RPL/2)
1505: - a minor bug is fixed in evaluation subroutine;
1506: - vim syntax file is improved;
1507: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1508: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
