208: by a new feature in glibc.
209: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
210: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
211: "ALL" IMPLICIT when it runs in interactive mode;
212: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
213: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
214: to use SAVE to manipulate global variables;
215: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
216: subroutines;
217: - fix major memory access violation in evaluation subroutine. Only occurs
218: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
219: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
220: when X was a vector or a table.

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

270: parent process was not interrupted if it is not group master process. To fix
271: this bug, SIGINJECT signal is not sent by child process but by control thread
272: in parent process;
273: - minor bug is fixed in data injection (POKE) that does not work as expected
274: when child process is protected by NRPROC.
275: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
276: - --enable-sysv-sems is added to configure script to use SystemV semaphores
277: functions instead of POSIX functions. This function is disabled or forced on
278: systems that does not provide correct POSIX or SysV semaphores subsystem;
279: - a dirty but not quick patch is written to workaround broken siginfo
280: structures. This patch has been successfully tested. It uses a segment of
281: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
282: (Unix PID);
283: - some OpenBSD's hacks are added;
284: - broken siginfo->si_pid field is now checked by configure script;

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

312: when this structure is included in IFERR/THEN/END structure and when an error is
313: caught;
314: - major bug is fixed in analyse() subroutine. When evaluation() returned error
315: in a compiled program, analyse() caught this error twice and randomly aborted
316: with a segmentation error;
317: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
318: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
319: signals;
320: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
321: matrix.

340: format in FCH (file descriptor) and SCK (socket descriptor);
341: - debug routines are improved;
342: - PROCID is added;
343: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
344: and to not use swap;
345: - major bug is fixed in sql support. SQL connections were closed in all chield
346: process;
347: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
348: discovered in Solaris thread safe allocators (libmalloc and libumem) that
349: are first fit class allocators. Solaris libmtmalloc works better and is
350: a best fit class allocator but its performance is poor than ptmalloc3
351: performance;
352: - major bug is fixed in ROW+ intrinsic (new row was not added where it
353: should);
354: - minor bugs are fixed in interruptions.c (semaphores values when error is

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

403: By default, implicit is set to "ALL";
404: - sqlite is upgraded to 3.6.23.1;
405: - openssl is upgraded to 1.0.0;
406: - major bug is fixed in RETURN intrinsic. It only occurs in evaluation
407: subroutine;
408: - table variable can now be sorted by SORT;
409: - some regressions between libtool 1.x and 2.x are fixed by workarouds in
410: Makefiles;
411: - -a command line option analyzes program (structure and syntax) and
412: sends preprocessor output to standard output. This option is used by
413: rplc (RPL/2 compiler).
414: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
415: - in formatted file, string format returned a variable length string even if
416: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
417: a variable length string and 'CHARACTER*(n)' a fixed length string;
418: - keyed access files support is added. Currently, only formatted files are
419: supported;
420: - direct access files support is added. Currenlty, these files can only be used
421: in formatted mode;
422: - virtual variables are now writte in UTF-8 and all special characters
423: in string are escaped;
424: - all formatted files are now converted into UTF-8;
425: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
426: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
427: each execution (md5 and sha1 sums) to enhance security. If one of these tools
428: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
429: on a non recoverable system error;
430: - openssl and sqlite3 libraries are added;
431: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
432: variable indicates RPL/2 root directory. If it is not set, root path
433: is given by configure script (d_exec_path);
434: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
435: - configure.in and makefile.am's are modified to add Cygwin support. Interix

441: fraction intead real one;
442: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
443: - Makefile.am are modified to authorize parallel builds;
444: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
445: and writes warning to standard output;
446: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)
447: - escape codes are now converted in formateur(), not in recherche_type() to
448: avoid a minor bug in EDIT and VISIT intrinsics;

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

463: - sockets options are now set before bind();
464: - shutdown() is added to all connected sockets;
465: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
466: list argument and inexistant elements).
467: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
468: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
469: signals sent to main process were not caught because DAEMON did not replace
470: old pid by new one;
471: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
472: evaluation when an error is reported from a subroutine in another subroutine.
473: For example, error was not caught in following program when it is executed with
474: -p option :
475: TEST << iferr TEST2 then end >>
476: TEST2 << 0 inv >>
477: - major bug is fixed in variable management. Some local variables were
478: seen as global ones;
479: - major bug is fixed in rplcore. Rplcore entered in dead lock when
480: script file contains a multibyte character;
481: - IN intrinsic is added;
482: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
483: returned false ;
484: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
485: programs;
486: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
487: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
488: strings were never closed;
489: - some bugs have been fixed in file management;

491: - major bug is fixed in -A command line option (NULL character is missing);
492: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
493: made by blocks (1024 bytes). When an incomplete multibyte sequence is
494: encountered at end of block, subroutine aborts with an execution error;
495: - major bug is fixed in OPEN (TCP/IPv4 sockets).
496: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
497: - DISP now locks stdout;
498: - rpliconv is added to replace standard iconv provided by operating system.
499: Indeed, conversion between different encodages requires transliteration
500: that is not offered by some iconv utility;
501: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
502: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
503: not be found), SYSEVAL enters in a dead lock;
504: - fprintf is replaced by some functions that allow transliterations between
505: locales;
506: - '"' can now be used in strings ("\"");
507: - iconv is called with -c in preprocessor stage. It is done to write
508: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
509: - double free is fixed in liberation() (type SQL, only occurs when locale is
510: set);
511: - LOCALIZATION, UCASE and LCASE are added;
512: - major bug is fixed in EXIT intrinsic that was able to return a false
513: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
514: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
515: used in onLoading from shared library, USE was pushed on stack as algebraic
516: expression;
517: - libiconv is upgraded to 1.13.1;
518: - gnuplot is upgraded to 4.2.6;
519: - gsl is upgraded to 1.13.
520: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
521: - pipe() is overwritten by a macro to avoid a system error. Communication
522: between process are done with pipes and these pipes are managed by a
523: specific asynchrone thread. If a script try to create more threads than
524: management thread can destroy, you can quickly achieve maximum number of
525: opened files and pipe() shall return a system error. This macro tries to create
526: pipes. If pipe() function returns an error, macro waits and retries. If
527: number of retries is greater than a hardcoded value, macro returns an error;
528: - major bug (deadlock) is fixed in process and thread management. I hope
529: this bug shall be the last one;
530: - major bug is fixed in DET intrinsic (determinant was computed without LU
531: diagonalization);
532: - SWAPCNTXT is added;
533: - minor bug is fixed in Makefile.am (licences rule).
534: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
535: - some bugfixes are added in process management;
536: - all process management is rewritten to avoid usage of defunct process
537: or thread number;
538: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
539: was called before a pending interruption5 (SIGFSTOP), signal handler uses
540: a freed semaphore and corrupts heap;
541: - CLRERR is added to erase previous errors;
542: - ERRN and ERRM return exception message and number;
543: - major bug is fixed in interruptions.c. All signal are now bufferised
544: when semaphore_liste_threads is null to avoid deadlock. This bug only
545: occured when STOP was sent to a dying thread or process (when this thread or
546: process was running retrait_thread());
547: - matrix rank is computed before matrix inversion;
548: - file locks are added to stdin and stdout. stderr is not locked because
549: all messages written by signal handlers are sent to stderr;
550: - configure.in script is modified to test gcc version and avoid a bug in
551: gcc older than 4.4;
552: - some benchmarks have been done :

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

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

692: that all programs that worked with old SQL intrinsic can now work with
693: SQLQUERY. With all new programs, you can open a real connection to databases;
694: - NRPROC is added. This new intrinsic is used to catch error from child
695: process. Without NRPROC, any errors returned by child process cause
696: main process to abort;
697: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
698: starts a new process). There are no mutexes in RPL/2 because all spawned process
699: use specific context. Nevertheless, shared variables and associated mutexes

786: - FUSE, RFUSE and CLRFUSE have been added;
787: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
788: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
789: workaround for this major bug. Nevertheless, all others capabilities seems to
790: work fine;
791: - '->' is modified to return error when program tries to initialiaze two
792: variables with the same name like
793: 1 0 -> I I << ... >>;

839: before starting interrupt evaluation;
840: - -f parameter is added when iconv is called;
841: - as old file program was bugged, a new option is added to configure script.
842: When configure is called with --disable-encoding-autodetection, make does not
843: try to detect source encoding. Please, do not use if RPL/2 can be built
844: without this option !
845: - new garbage collector (and more efficient) is written;
846: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
847: not support real time signals, RPL/2 cannot use multitasking functions;

849: - -p option is added. With this option, all scripts are compiled before
850: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
851: 40% faster;
852: - read and write operations in pipe() are rewritten to be sure that such
853: operations are atomic;
854: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1050: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1051: versions of PROTECT and UNPROTECT that only deal with global variables
1052: (see RCL/SAVE);
1053: - variable management routines have been rewritten. The new ones are
1054: uncompatible with the old ones. Before these changes, a local variable
1055: was exported to a child subroutine, but cannot be modified into this

1379: - NOT is not correctly formatted in formateur.c:
1380: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1381: with a NOTZ function !
1382: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1471: statistical variable, or "DISABLED" if its type is not one of the type of
1472: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1473: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1474: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1475: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1476: disabled. Arguments of EXTERNAL are case sensitive because the external
1477: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1478: of known external functions but add the new list to the last. { "all" }
1479: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1480: external names of the known functions;
1481: - mkrplso.in is modified.
1482: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1496: VISIT does not find a name in level 1;
1497: - configure.in script is modified to add a new test (--enable-debug
1498: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1499: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1500: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1501: 'MATRIX' { 2 2 3 } GETR;
1502: - LOGSCALE intrinsic is improved and now, it can be used as
1503: { "main" "auxiliary" X Y } LOGSCALE;
1504: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1505: same than AXES:
1506: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1507: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1508: { { -10 10 } "automatic" } SCALE.
1509: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1510: because it changes only the dimension of the screen. To have a logarithmic
1511: scale, you must use LOGSCALE intrinsic:
1512: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1513: screen on second scale;
1514: - { X X } autoscale and { Y Y } logscale are now invalid;
1515: - *D is added (depth multiplication, for 3D graphics);
1516: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y

1534: in 0);
1535: - LAST is disabled in the main loop of DRAW intrinsic;
1536: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1537: evaluation of an equation, the system stack is returned corrupted to the
1538: sequencer;
1539: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1540: of a loop are not integer or real.

1573: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1574: is a quick and dirty workaround...);
