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

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

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

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

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

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

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

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

433: - TeX files are now written in UTF-8 even default locale differs;
434: - minor bug is fixed in ->STR (escaped characters);
435: - minor bug is fixed in ->Q intrinsic. Resultat is returned as integer
436: fraction intead real one;
437: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
438: - Makefile.am are modified to authorize parallel builds;
439: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
440: and writes warning to standard output;
441: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)
442: - escape codes are now converted in formateur(), not in recherche_type() to
443: avoid a minor bug in EDIT and VISIT intrinsics;

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

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

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

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

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

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

808: - VERIFY intrinsic is written;
809: - PSHCNTXT and PULCNTXT are added (PSHCNTXT pushes context on an
810: internal contexts stack, PULCNTXT pulls contexts from this internal stack).
811: Main usages of these intrinsics are in conjonction with IFERR or with
812: software interrupts;
813: - HEAD, TAIL and REVLIST intrinsics are added;

834: before starting interrupt evaluation;
835: - -f parameter is added when iconv is called;
836: - as old file program was bugged, a new option is added to configure script.
837: When configure is called with --disable-encoding-autodetection, make does not
838: try to detect source encoding. Please, do not use if RPL/2 can be built
839: without this option !
840: - new garbage collector (and more efficient) is written;
841: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
842: not support real time signals, RPL/2 cannot use multitasking functions;
843: - error returned by preprocessor are now catched by RPL/2;
844: - -p option is added. With this option, all scripts are compiled before
845: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
846: 40% faster;
847: - read and write operations in pipe() are rewritten to be sure that such
848: operations are atomic;
849: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be
850: linear;

1044: - PROTECT and UNPROTECT are added to protect variables against write
1045: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1046: versions of PROTECT and UNPROTECT that only deal with global variables
1047: (see RCL/SAVE);
1048: - variable management routines have been rewritten. The new ones are
1049: uncompatible with the old ones. Before these changes, a local variable
1050: was exported to a child subroutine, but cannot be modified into this
1051: child subroutine. Now, a local variable is accessible only in its subroutine;
1052: - SAVE intrinsic is added to manipulate global variables;

1374: - NOT is not correctly formatted in formateur.c:
1375: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1376: with a NOTZ function !
1377: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1466: statistical variable, or "DISABLED" if its type is not one of the type of
1467: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1468: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1469: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1470: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1471: disabled. Arguments of EXTERNAL are case sensitive because the external
1472: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1473: of known external functions but add the new list to the last. { "all" }
1474: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1475: external names of the known functions;
1476: - mkrplso.in is modified.
1477: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1491: VISIT does not find a name in level 1;
1492: - configure.in script is modified to add a new test (--enable-debug
1493: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1494: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1495: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1496: 'MATRIX' { 2 2 3 } GETR;
1497: - LOGSCALE intrinsic is improved and now, it can be used as
1498: { "main" "auxiliary" X Y } LOGSCALE;
1499: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1500: same than AXES:
1501: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1502: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1503: { { -10 10 } "automatic" } SCALE.
1504: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1505: because it changes only the dimension of the screen. To have a logarithmic
1506: scale, you must use LOGSCALE intrinsic:
1507: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1508: screen on second scale;
1509: - { X X } autoscale and { Y Y } logscale are now invalid;
1510: - *D is added (depth multiplication, for 3D graphics);
1511: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1512: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
