190: by a new feature in glibc.
191: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
192: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
193: "ALL" IMPLICIT when it runs in interactive mode;
194: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
195: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
196: to use SAVE to manipulate global variables;
197: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
198: subroutines;
199: - fix major memory access violation in evaluation subroutine. Only occurs
200: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
201: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
202: when X was a vector or a table.

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

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

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

292: - BACKTRACE intrinsic is added;
293: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
294: when this structure is included in IFERR/THEN/END structure and when an error is
295: caught;
296: - major bug is fixed in analyse() subroutine. When evaluation() returned error
297: in a compiled program, analyse() caught this error twice and randomly aborted
298: with a segmentation error;
299: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
300: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
301: signals;
302: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
303: matrix.

322: format in FCH (file descriptor) and SCK (socket descriptor);
323: - debug routines are improved;
324: - PROCID is added;
325: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
326: and to not use swap;
327: - major bug is fixed in sql support. SQL connections were closed in all chield
328: process;
329: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
330: discovered in Solaris thread safe allocators (libmalloc and libumem) that
331: are first fit class allocators. Solaris libmtmalloc works better and is
332: a best fit class allocator but its performance is poor than ptmalloc3
333: performance;
334: - major bug is fixed in ROW+ intrinsic (new row was not added where it
335: should);
336: - minor bugs are fixed in interruptions.c (semaphores values when error is
337: caught);
338: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
339: created by SPAWN;

349: information about shared variable was not copied to new processus structure;
350: - some little memory leaks are fixed in evaluation(), recherche_type() and
351: sequenceur(). They only occured when syntax error were caught;
352: - IMPLICIT causes execution error instead system error;
353: - Hurd support is improved but currently broken because Hurd does not support

391: - some regressions between libtool 1.x and 2.x are fixed by workarouds in
392: Makefiles;
393: - -a command line option analyzes program (structure and syntax) and
394: sends preprocessor output to standard output. This option is used by
395: rplc (RPL/2 compiler).
396: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
397: - in formatted file, string format returned a variable length string even if
398: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
399: a variable length string and 'CHARACTER*(n)' a fixed length string;
400: - keyed access files support is added. Currently, only formatted files are
401: supported;
402: - direct access files support is added. Currenlty, these files can only be used
403: in formatted mode;
404: - virtual variables are now writte in UTF-8 and all special characters
405: in string are escaped;
406: - all formatted files are now converted into UTF-8;
407: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
408: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
409: each execution (md5 and sha1 sums) to enhance security. If one of these tools
410: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
411: on a non recoverable system error;
412: - openssl and sqlite3 libraries are added;
413: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
414: variable indicates RPL/2 root directory. If it is not set, root path
415: is given by configure script (d_exec_path);
416: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

449: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
450: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
451: signals sent to main process were not caught because DAEMON did not replace
452: old pid by new one;
453: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
454: evaluation when an error is reported from a subroutine in another subroutine.
455: For example, error was not caught in following program when it is executed with
456: -p option :
457: TEST << iferr TEST2 then end >>
458: TEST2 << 0 inv >>
459: - major bug is fixed in variable management. Some local variables were
460: seen as global ones;
461: - major bug is fixed in rplcore. Rplcore entered in dead lock when
462: script file contains a multibyte character;
463: - IN intrinsic is added;
464: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
465: returned false ;
466: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
467: programs;
468: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
469: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
470: strings were never closed;
471: - some bugs have been fixed in file management;

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

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

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

675: SQLQUERY. With all new programs, you can open a real connection to databases;
676: - NRPROC is added. This new intrinsic is used to catch error from child
677: process. Without NRPROC, any errors returned by child process cause
678: main process to abort;
679: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
680: starts a new process). There are no mutexes in RPL/2 because all spawned process
681: use specific context. Nevertheless, shared variables and associated mutexes

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

831: - -p option is added. With this option, all scripts are compiled before
832: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
833: 40% faster;
834: - read and write operations in pipe() are rewritten to be sure that such
835: operations are atomic;
836: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1031: - PROTECT and UNPROTECT are added to protect variables against write
1032: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1033: versions of PROTECT and UNPROTECT that only deal with global variables
1034: (see RCL/SAVE);
1035: - variable management routines have been rewritten. The new ones are
1036: uncompatible with the old ones. Before these changes, a local variable
1037: was exported to a child subroutine, but cannot be modified into this
1038: child subroutine. Now, a local variable is accessible only in its subroutine;
1039: - SAVE intrinsic is added to manipulate global variables;

1361: - NOT is not correctly formatted in formateur.c:
1362: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1363: with a NOTZ function !
1364: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1367: - RPL/2 is tested with efence and valgrind;
1368: - configure.in script is modified;
1369: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1430: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1431: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1432: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1449: - SCLS is added;
1450: - DRWS now uses COLS to draw 2D graphics;
1451: - PPAR and SPAR are written. SPAR returns a list that contains the
1452: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1453: statistical variable, or "DISABLED" if its type is not one of the type of
1454: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1455: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1456: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1457: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1458: disabled. Arguments of EXTERNAL are case sensitive because the external
1459: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1460: of known external functions but add the new list to the last. { "all" }
1461: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1462: external names of the known functions;
1463: - mkrplso.in is modified.
1464: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1465: - vim syntax file is upgraded;
1466: - a minor mistake is fixed in recherche_instruction_suivante();
1467: - some minor memory leaks are fixed in recherche_type() function. They only

1477: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1478: VISIT does not find a name in level 1;
1479: - configure.in script is modified to add a new test (--enable-debug
1480: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1481: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1482: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1483: 'MATRIX' { 2 2 3 } GETR;
1484: - LOGSCALE intrinsic is improved and now, it can be used as
1485: { "main" "auxiliary" X Y } LOGSCALE;
1486: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1487: same than AXES:
1488: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1489: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1490: { { -10 10 } "automatic" } SCALE.
1491: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1492: because it changes only the dimension of the screen. To have a logarithmic
1493: scale, you must use LOGSCALE intrinsic:
1494: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1495: screen on second scale;
1496: - { X X } autoscale and { Y Y } logscale are now invalid;
1497: - *D is added (depth multiplication, for 3D graphics);
1498: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1499: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1500: - a major bug is fixed in GETI instrinsic when it is used with a name
1501: that contains a matrix or a vector (bad upper bounds conditions in
1502: incrementation);
1503: - DISP intrinsic now uses the 33-th flag. When it is not set
1504: (default), a final carriage return is sent to the terminal;
1505: - AXES intrinsic only takes a list that can contains the keywork
1506: "main" or "auxiliary". Before this modification, this keyword was in
1507: the first stack level;
1508: - vim syntax file is upgraded;
1509: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1510: option;
