1: * Tue Dec 18 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.13 (RPL/2)
2: - new NATIVE*(*) data format is added. By default, native*(*) is used
3: to write data without precision loss. It can also be used to write
4: complex objects like expressions, lists or tables;
5: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
6: internal value was good but RPL/2 was not able to correctly display
7: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented
8: in integer. All abs(), fabs() and labs() present in source code have ben checked
9: to avoid this kind of bug;
10: - unformatted sockets are now usable as unformatted files;

53: intrinsic;
54: - CRITICAL/END structure is added. When program enters in a critical
55: section, all other threads of the same process sleep until program leaves
56: critical section.

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

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

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

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

322: - BACKTRACE intrinsic is added;
323: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
324: when this structure is included in IFERR/THEN/END structure and when an error is
325: caught;
326: - major bug is fixed in analyse() subroutine. When evaluation() returned error
327: in a compiled program, analyse() caught this error twice and randomly aborted
328: with a segmentation error;
329: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
330: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
331: signals;
332: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
333: matrix.

341: programs;
342: - some memory leaks are fixed in process management (SPAWN and DETACH);
343: - version verification is added to shared objects;
344: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
345: linux (false mremap() prototype);

352: format in FCH (file descriptor) and SCK (socket descriptor);
353: - debug routines are improved;
354: - PROCID is added;
355: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
356: and to not use swap;
357: - major bug is fixed in sql support. SQL connections were closed in all chield
358: process;
359: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
360: discovered in Solaris thread safe allocators (libmalloc and libumem) that
361: are first fit class allocators. Solaris libmtmalloc works better and is
362: a best fit class allocator but its performance is poor than ptmalloc3
363: performance;
364: - major bug is fixed in ROW+ intrinsic (new row was not added where it
365: should);

379: information about shared variable was not copied to new processus structure;
380: - some little memory leaks are fixed in evaluation(), recherche_type() and
381: sequenceur(). They only occured when syntax error were caught;
382: - IMPLICIT causes execution error instead system error;
383: - Hurd support is improved but currently broken because Hurd does not support
384: SIG_INFO. Work in progress;
385: - OpenBSD specific support is removed from sources;
386: - support for Mac OS X and Windows/Cygwin is added.
387: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

425: rplc (RPL/2 compiler).
426: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
427: - in formatted file, string format returned a variable length string even if
428: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
429: a variable length string and 'CHARACTER*(n)' a fixed length string;
430: - keyed access files support is added. Currently, only formatted files are
431: supported;
432: - direct access files support is added. Currenlty, these files can only be used
433: in formatted mode;
434: - virtual variables are now writte in UTF-8 and all special characters
435: in string are escaped;
436: - all formatted files are now converted into UTF-8;
437: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
438: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
439: each execution (md5 and sha1 sums) to enhance security. If one of these tools
440: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
441: on a non recoverable system error;
442: - openssl and sqlite3 libraries are added;
443: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
444: variable indicates RPL/2 root directory. If it is not set, root path
445: is given by configure script (d_exec_path);
446: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
447: - configure.in and makefile.am's are modified to add Cygwin support. Interix

479: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
480: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
481: signals sent to main process were not caught because DAEMON did not replace
482: old pid by new one;
483: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
484: evaluation when an error is reported from a subroutine in another subroutine.
485: For example, error was not caught in following program when it is executed with
486: -p option :
487: TEST << iferr TEST2 then end >>
488: TEST2 << 0 inv >>
489: - major bug is fixed in variable management. Some local variables were
490: seen as global ones;
491: - major bug is fixed in rplcore. Rplcore entered in dead lock when
492: script file contains a multibyte character;
493: - IN intrinsic is added;
494: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
495: returned false ;
496: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
497: programs;
498: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
499: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
500: strings were never closed;

503: - major bug is fixed in -A command line option (NULL character is missing);
504: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
505: made by blocks (1024 bytes). When an incomplete multibyte sequence is
506: encountered at end of block, subroutine aborts with an execution error;
507: - major bug is fixed in OPEN (TCP/IPv4 sockets).
508: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
509: - DISP now locks stdout;
510: - rpliconv is added to replace standard iconv provided by operating system.
511: Indeed, conversion between different encodages requires transliteration
512: that is not offered by some iconv utility;
513: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
514: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
515: not be found), SYSEVAL enters in a dead lock;
516: - fprintf is replaced by some functions that allow transliterations between
517: locales;
518: - '"' can now be used in strings ("\"");
519: - iconv is called with -c in preprocessor stage. It is done to write
520: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
521: - double free is fixed in liberation() (type SQL, only occurs when locale is
522: set);
523: - LOCALIZATION, UCASE and LCASE are added;
524: - major bug is fixed in EXIT intrinsic that was able to return a false
525: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
526: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
527: used in onLoading from shared library, USE was pushed on stack as algebraic

530: - gnuplot is upgraded to 4.2.6;
531: - gsl is upgraded to 1.13.

533: - pipe() is overwritten by a macro to avoid a system error. Communication
534: between process are done with pipes and these pipes are managed by a
535: specific asynchrone thread. If a script try to create more threads than
536: management thread can destroy, you can quickly achieve maximum number of
537: opened files and pipe() shall return a system error. This macro tries to create
538: pipes. If pipe() function returns an error, macro waits and retries. If
539: number of retries is greater than a hardcoded value, macro returns an error;
540: - major bug (deadlock) is fixed in process and thread management. I hope
541: this bug shall be the last one;
542: - major bug is fixed in DET intrinsic (determinant was computed without LU
543: diagonalization);

548: - all process management is rewritten to avoid usage of defunct process
549: or thread number;
550: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
551: was called before a pending interruption5 (SIGFSTOP), signal handler uses
552: a freed semaphore and corrupts heap;
553: - CLRERR is added to erase previous errors;
554: - ERRN and ERRM return exception message and number;
555: - major bug is fixed in interruptions.c. All signal are now bufferised
556: when semaphore_liste_threads is null to avoid deadlock. This bug only
557: occured when STOP was sent to a dying thread or process (when this thread or
558: process was running retrait_thread());
559: - matrix rank is computed before matrix inversion;
560: - file locks are added to stdin and stdout. stderr is not locked because
561: all messages written by signal handlers are sent to stderr;
562: - configure.in script is modified to test gcc version and avoid a bug in
563: gcc older than 4.4;

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

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

704: that all programs that worked with old SQL intrinsic can now work with
705: SQLQUERY. With all new programs, you can open a real connection to databases;
706: - NRPROC is added. This new intrinsic is used to catch error from child
707: process. Without NRPROC, any errors returned by child process cause
708: main process to abort;
709: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
710: starts a new process). There are no mutexes in RPL/2 because all spawned process
711: use specific context. Nevertheless, shared variables and associated mutexes
712: should be added;

1518: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1519: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1520: { { -10 10 } "automatic" } SCALE.
1521: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1522: because it changes only the dimension of the screen. To have a logarithmic
1523: scale, you must use LOGSCALE intrinsic:
1524: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1525: screen on second scale;
1526: - { X X } autoscale and { Y Y } logscale are now invalid;
1527: - *D is added (depth multiplication, for 3D graphics);
1528: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1529: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1530: - a major bug is fixed in GETI instrinsic when it is used with a name
1531: that contains a matrix or a vector (bad upper bounds conditions in
1532: incrementation);
1533: - DISP intrinsic now uses the 33-th flag. When it is not set
1534: (default), a final carriage return is sent to the terminal;
1535: - AXES intrinsic only takes a list that can contains the keywork
1536: "main" or "auxiliary". Before this modification, this keyword was in
1537: the first stack level;
1538: - vim syntax file is upgraded;
1539: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1540: option;
1541: - LAST is now disabled in the main loop of INT intrinsic;
1542: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

1544: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1545: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1546: in 0);
1547: - LAST is disabled in the main loop of DRAW intrinsic;
1548: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1549: evaluation of an equation, the system stack is returned corrupted to the
1550: sequencer;
1551: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1552: of a loop are not integer or real.
1553: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1556: add some tests in gestion_variables.c;
1557: - recherche_type() subroutine ad some other connex subroutines are improved.
1558: Now, some syntax errors about object are caught and do not perform sequencer
1559: hangup;

1563: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1564: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1565: the boxwidth, 1 by default);
1566: - recherche_type() is rewritten to be faster;
1567: - gsl is upgraded (release 1.3);
1568: - ncurses is upgraded and patched (release 5.3);
1569: - recherche_instruction_suivante() is fixed (string research with included
1570: '"') and rewritten to be faster;

1582: - vim syntax file is improved;
1583: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1584: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1585: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1586: is a quick and dirty workaround...);
1587: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1588: - rplconvert is improved.
1589: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
