1: * Tue Dec 18 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.13 (RPL/2)
2: - all internal data are now stored in 64 bits wide integers (even is 32 bits
3: ABI is selected);
4: - major bug is fixed in recherche_instruction_suivante(). In some
5: circumstances, this function can return a spurious error;
6: - new NATIVE*(*) data format is added. By default, native*(*) is used
7: to write data without precision loss. It can also be used to write
8: complex objects like expressions, lists or tables;
9: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
10: internal value was good but RPL/2 was not able to correctly display
11: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented
12: in integer. All abs(), fabs() and labs() present in source code have ben checked
13: to avoid this kind of bug;
14: - unformatted sockets are now usable as unformatted files;
15: - BACKSPACE now runs on unformatted file;
16: - major bug is fixed in BACKSPACE that didn't check if '"' characters were

55: interrupt a loop from a subroutine within a compiled programm;
56: - workaround to avoid strange bug on slow network is written in READ
57: intrinsic;
58: - CRITICAL/END structure is added. When program enters in a critical
59: section, all other threads of the same process sleep until program leaves
60: critical section.

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

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

286: parent process was not interrupted if it is not group master process. To fix
287: this bug, SIGINJECT signal is not sent by child process but by control thread
288: in parent process;
289: - minor bug is fixed in data injection (POKE) that does not work as expected
290: when child process is protected by NRPROC.
291: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
292: - --enable-sysv-sems is added to configure script to use SystemV semaphores
293: functions instead of POSIX functions. This function is disabled or forced on
294: systems that does not provide correct POSIX or SysV semaphores subsystem;
295: - a dirty but not quick patch is written to workaround broken siginfo
296: structures. This patch has been successfully tested. It uses a segment of
297: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
298: (Unix PID);
299: - some OpenBSD's hacks are added;
300: - broken siginfo->si_pid field is now checked by configure script;
301: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

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

326: - BACKTRACE intrinsic is added;
327: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
328: when this structure is included in IFERR/THEN/END structure and when an error is
329: caught;
330: - major bug is fixed in analyse() subroutine. When evaluation() returned error
331: in a compiled program, analyse() caught this error twice and randomly aborted
332: with a segmentation error;
333: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
334: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
335: signals;
336: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
337: matrix.
338: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

342: - openssl is upgraded to 1.0.0a;
343: - interrupt stacks are now FIFO instead of LIFO;
344: - debug memory allocation subroutines are improved to run in multithreaded
345: programs;
346: - some memory leaks are fixed in process management (SPAWN and DETACH);
347: - version verification is added to shared objects;
348: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
349: linux (false mremap() prototype);
350: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
351: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
352: - all '-' are replaced by '_' in random generator list;

356: format in FCH (file descriptor) and SCK (socket descriptor);
357: - debug routines are improved;
358: - PROCID is added;
359: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
360: and to not use swap;
361: - major bug is fixed in sql support. SQL connections were closed in all chield
362: process;
363: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
364: discovered in Solaris thread safe allocators (libmalloc and libumem) that
365: are first fit class allocators. Solaris libmtmalloc works better and is
366: a best fit class allocator but its performance is poor than ptmalloc3
367: performance;
368: - major bug is fixed in ROW+ intrinsic (new row was not added where it
369: should);
370: - minor bugs are fixed in interruptions.c (semaphores values when error is
371: caught);
372: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
373: created by SPAWN;

381: from an expression;
382: - major bug is fixed in copie_etat_processus(). A field that contains
383: information about shared variable was not copied to new processus structure;
384: - some little memory leaks are fixed in evaluation(), recherche_type() and
385: sequenceur(). They only occured when syntax error were caught;
386: - IMPLICIT causes execution error instead system error;
387: - Hurd support is improved but currently broken because Hurd does not support
388: SIG_INFO. Work in progress;
389: - OpenBSD specific support is removed from sources;
390: - support for Mac OS X and Windows/Cygwin is added.

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

458: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
459: - Makefile.am are modified to authorize parallel builds;
460: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
461: and writes warning to standard output;

483: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
484: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
485: signals sent to main process were not caught because DAEMON did not replace
486: old pid by new one;
487: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
488: evaluation when an error is reported from a subroutine in another subroutine.
489: For example, error was not caught in following program when it is executed with
490: -p option :
491: TEST << iferr TEST2 then end >>
492: TEST2 << 0 inv >>
493: - major bug is fixed in variable management. Some local variables were
494: seen as global ones;

496: script file contains a multibyte character;
497: - IN intrinsic is added;
498: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
499: returned false ;
500: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
501: programs;
502: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
503: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
504: strings were never closed;

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

534: - gnuplot is upgraded to 4.2.6;
535: - gsl is upgraded to 1.13.

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

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

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

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

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

865: - -p option is added. With this option, all scripts are compiled before
866: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
867: 40% faster;
868: - read and write operations in pipe() are rewritten to be sure that such
869: operations are atomic;

1064: With STATIC, next variables created by '->' are static;
1065: - PROTECT and UNPROTECT are added to protect variables against write
1066: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1067: versions of PROTECT and UNPROTECT that only deal with global variables
1068: (see RCL/SAVE);
1069: - variable management routines have been rewritten. The new ones are
1070: uncompatible with the old ones. Before these changes, a local variable
1071: was exported to a child subroutine, but cannot be modified into this
1072: child subroutine. Now, a local variable is accessible only in its subroutine;
1073: - SAVE intrinsic is added to manipulate global variables;

1516: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1517: 'MATRIX' { 2 2 3 } GETR;
1518: - LOGSCALE intrinsic is improved and now, it can be used as
1519: { "main" "auxiliary" X Y } LOGSCALE;
1520: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1521: same than AXES:
1522: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1523: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1524: { { -10 10 } "automatic" } SCALE.
1525: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1526: because it changes only the dimension of the screen. To have a logarithmic
1527: scale, you must use LOGSCALE intrinsic:
1528: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1529: screen on second scale;
1530: - { X X } autoscale and { Y Y } logscale are now invalid;
1531: - *D is added (depth multiplication, for 3D graphics);
1532: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1533: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1534: - a major bug is fixed in GETI instrinsic when it is used with a name
1535: that contains a matrix or a vector (bad upper bounds conditions in
1536: incrementation);
1537: - DISP intrinsic now uses the 33-th flag. When it is not set
1538: (default), a final carriage return is sent to the terminal;
1539: - AXES intrinsic only takes a list that can contains the keywork
1540: "main" or "auxiliary". Before this modification, this keyword was in
1541: the first stack level;
1542: - vim syntax file is upgraded;
1543: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1544: option;
1545: - LAST is now disabled in the main loop of INT intrinsic;
1546: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

1548: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1549: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1550: in 0);
1551: - LAST is disabled in the main loop of DRAW intrinsic;
1552: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1553: evaluation of an equation, the system stack is returned corrupted to the
1554: sequencer;
1555: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1556: of a loop are not integer or real.
1557: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1559: have the same name. To improve the compilation() subroutine, I have to
1560: add some tests in gestion_variables.c;
1561: - recherche_type() subroutine ad some other connex subroutines are improved.
1562: Now, some syntax errors about object are caught and do not perform sequencer
1563: hangup;

1567: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1568: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1569: the boxwidth, 1 by default);
1570: - recherche_type() is rewritten to be faster;
1571: - gsl is upgraded (release 1.3);
1572: - ncurses is upgraded and patched (release 5.3);
1573: - recherche_instruction_suivante() is fixed (string research with included
1574: '"') and rewritten to be faster;

1588: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1589: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1590: is a quick and dirty workaround...);
1591: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1592: - rplconvert is improved.
1593: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
