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

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

239: parent process was not interrupted if it is not group master process. To fix
240: this bug, SIGINJECT signal is not sent by child process but by control thread
241: in parent process;
242: - minor bug is fixed in data injection (POKE) that does not work as expected
243: when child process is protected by NRPROC.
244: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
245: - --enable-sysv-sems is added to configure script to use SystemV semaphores
246: functions instead of POSIX functions. This function is disabled or forced on
247: systems that does not provide correct POSIX or SysV semaphores subsystem;
248: - a dirty but not quick patch is written to workaround broken siginfo
249: structures. This patch has been successfully tested. It uses a segment of
250: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
251: (Unix PID);
252: - some OpenBSD's hacks are added;
253: - broken siginfo->si_pid field is now checked by configure script;

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

279: - BACKTRACE intrinsic is added;
280: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
281: when this structure is included in IFERR/THEN/END structure and when an error is
282: caught;
283: - major bug is fixed in analyse() subroutine. When evaluation() returned error
284: in a compiled program, analyse() caught this error twice and randomly aborted
285: with a segmentation error;
286: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
287: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
288: signals;
289: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
290: matrix.
291: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

301: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
302: linux (false mremap() prototype);
303: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.

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

336: information about shared variable was not copied to new processus structure;
337: - some little memory leaks are fixed in evaluation(), recherche_type() and
338: sequenceur(). They only occured when syntax error were caught;
339: - IMPLICIT causes execution error instead system error;
340: - Hurd support is improved but currently broken because Hurd does not support
341: SIG_INFO. Work in progress;

389: - direct access files support is added. Currenlty, these files can only be used
390: in formatted mode;
391: - virtual variables are now writte in UTF-8 and all special characters
392: in string are escaped;
393: - all formatted files are now converted into UTF-8;
394: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
395: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
396: each execution (md5 and sha1 sums) to enhance security. If one of these tools
397: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
398: on a non recoverable system error;
399: - openssl and sqlite3 libraries are added;
400: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
401: variable indicates RPL/2 root directory. If it is not set, root path
402: is given by configure script (d_exec_path);
403: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

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

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

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

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

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

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

818: - -p option is added. With this option, all scripts are compiled before
819: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
820: 40% faster;
821: - read and write operations in pipe() are rewritten to be sure that such
822: operations are atomic;
823: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1019: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1020: versions of PROTECT and UNPROTECT that only deal with global variables
1021: (see RCL/SAVE);
1022: - variable management routines have been rewritten. The new ones are
1023: uncompatible with the old ones. Before these changes, a local variable
1024: was exported to a child subroutine, but cannot be modified into this
1025: child subroutine. Now, a local variable is accessible only in its subroutine;
1026: - SAVE intrinsic is added to manipulate global variables;

1347: fine...);
1348: - NOT is not correctly formatted in formateur.c:
1349: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1350: with a NOTZ function !
1351: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1354: - RPL/2 is tested with efence and valgrind;
1355: - configure.in script is modified;
1356: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1417: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1418: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1419: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1436: - SCLS is added;
1437: - DRWS now uses COLS to draw 2D graphics;
1438: - PPAR and SPAR are written. SPAR returns a list that contains the
1439: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1440: statistical variable, or "DISABLED" if its type is not one of the type of
1441: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1442: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1443: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1444: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1445: disabled. Arguments of EXTERNAL are case sensitive because the external
1446: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1447: of known external functions but add the new list to the last. { "all" }
1448: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1449: external names of the known functions;
1450: - mkrplso.in is modified.
1451: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1452: - vim syntax file is upgraded;
1453: - a minor mistake is fixed in recherche_instruction_suivante();

1463: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1464: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1465: VISIT does not find a name in level 1;
1466: - configure.in script is modified to add a new test (--enable-debug
1467: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1468: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1469: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1470: 'MATRIX' { 2 2 3 } GETR;
1471: - LOGSCALE intrinsic is improved and now, it can be used as
1472: { "main" "auxiliary" X Y } LOGSCALE;
1473: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1474: same than AXES:
1475: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1476: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1477: { { -10 10 } "automatic" } SCALE.
1478: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1479: because it changes only the dimension of the screen. To have a logarithmic
1480: scale, you must use LOGSCALE intrinsic:
1481: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1482: screen on second scale;
1483: - { X X } autoscale and { Y Y } logscale are now invalid;
1484: - *D is added (depth multiplication, for 3D graphics);
1485: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1486: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1487: - a major bug is fixed in GETI instrinsic when it is used with a name
1488: that contains a matrix or a vector (bad upper bounds conditions in
1489: incrementation);
1490: - DISP intrinsic now uses the 33-th flag. When it is not set
1491: (default), a final carriage return is sent to the terminal;
1492: - AXES intrinsic only takes a list that can contains the keywork
1493: "main" or "auxiliary". Before this modification, this keyword was in
1494: the first stack level;
1495: - vim syntax file is upgraded;
1496: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1497: option;
1498: - LAST is now disabled in the main loop of INT intrinsic;
1499: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1500: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1501: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1502: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1503: in 0);
1504: - LAST is disabled in the main loop of DRAW intrinsic;
1505: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1506: evaluation of an equation, the system stack is returned corrupted to the
1507: sequencer;
1508: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1509: of a loop are not integer or real.
1510: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
