162: - major bug is fixed in STD format (1E7 sq prints 1);
163: - major bug is fixed in READ intrinsic (socket). This bug was introduced
164: by a new feature in glibc.
165: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
166: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
167: "ALL" IMPLICIT when it runs in interactive mode;
168: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
169: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
170: to use SAVE to manipulate global variables;
171: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
172: subroutines;
173: - fix major memory access violation in evaluation subroutine. Only occurs
174: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
175: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
176: when X was a vector or a table.
1.63 bertrand 177: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)
178: - Gnuplot is upgraded;

187: Known escape sequences are \", \b, \n, \t, \x?? and \\.
1.60 bertrand 188: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
189: - Ncurses is upgraded to 5.8;
190: - ALARM is fixed by filling isdst field;
191: - catch ECONNRESET in write intrinsic to return an execution error instead of
192: system one;
193: - fix a typo in HELP intrinsic;
194: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;
1.57 bertrand 195: - Lapack is upgraded to 3.3.0;
1.58 bertrand 196: - libmtmalloc is now default Solaris allocator;
1.56 bertrand 197: - ncurses is upgraded;
1.60 bertrand 198: - regression introduced by 4.0.19 is fixed in signal management.
1.59 bertrand 199: Interruption1() could be called from itself and raises bus error (on sparc) or
1.55 bertrand 200: segmentation fault;
201: - sqlite is upgraded to 3.7.4;
1.54 bertrand 202: - OpenSSL is upgraded to 1.0.0c;

1.53 bertrand 205: - gnuplot is upgraded to 4.4.2 due to major bugs.
1.52 bertrand 206: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
207: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
208: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
209: corruption. As internal memory management have been improved, a best fit
210: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 211: - gnuplot is upgraded to 4.4.1;
212: - deadlock is fixed in signal handlers: same mutex was used in standard
213: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
214: and signal handlers. A new signal handler specific mutex is added;
215: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
216: that has to be evaluated by ->NUM;
1.49 bertrand 217: - rplfile build process is modify to be sure that rplfile is not modified
218: after rpl build stage (to be sure that rplfile checksum is not modified after
219: rpl compilation);
1.51 bertrand 220: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
221: modified to remove yacc code and renamed;
1.47 bertrand 222: - some workarounds have been written to not use buggy klibc SystemV IPCS.
223: ABORT now works on eComStation;
224: - sqlite is upgraded to 3.7.2;
225: - bug is fixed in software interrupts. When both process have different PID,
226: parent process was not interrupted if it is not group master process. To fix
227: this bug, SIGINJECT signal is not sent by child process but by control thread
228: in parent process;
1.46 bertrand 229: - minor bug is fixed in data injection (POKE) that does not work as expected
230: when child process is protected by NRPROC.
1.44 bertrand 231: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 232: - --enable-sysv-sems is added to configure script to use SystemV semaphores
233: functions instead of POSIX functions. This function is disabled or forced on
234: systems that does not provide correct POSIX or SysV semaphores subsystem;
235: - a dirty but not quick patch is written to workaround broken siginfo
236: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 237: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 238: (Unix PID);
1.41 bertrand 239: - some OpenBSD's hacks are added;
240: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 241: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
242: - random generator is cloned by SPAWN;
243: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
1.39 bertrand 244: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 245: or freeaddrinfo;
1.39 bertrand 246: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
247: - major bug is fixed in CHR intrinsic when obtained character is not printable;
248: - Lapack is upgraded to 3.2.2;
1.37 bertrand 249: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
1.36 bertrand 250: - TOKENIZE is now able to convert escape sequences;
251: - ATPOKE and CLRATPOKE new intrinsics are added;
252: - --enable-full-static configure flag is added. With this flag, mysql and
253: postgresql libraries are statically linked in rpl executable;
254: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 255: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 256: - units is upgraded to 1.88;
257: - another major bug is fixed in the same variable creation subroutine.
258: Level 0 and 1 variables adresses were swapped when a global variable masked
259: a name of RPL/2 routine;
1.35 bertrand 260: - major bug is fixed in global variable creation subroutine. When a global
261: variable was created and when a local variable existed with the same name,
262: computed address of global variable was wrong;
263: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
264: is forced in front of all libraries.
1.34 bertrand 265: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
266: - BACKTRACE intrinsic is added;
267: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
268: when this structure is included in IFERR/THEN/END structure and when an error is
269: caught;
270: - major bug is fixed in analyse() subroutine. When evaluation() returned error
271: in a compiled program, analyse() caught this error twice and randomly aborted
272: with a segmentation error;
273: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
274: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
275: signals;
276: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
277: matrix.
1.33 bertrand 278: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
279: - minor bug is fixed in evaluation() subroutine. With this patch, same program
280: returns same result with or without -p flag;
281: - ncurses 5.7 is upgraded to 20100619;
282: - openssl is upgraded to 1.0.0a;
1.32 bertrand 283: - interrupt stacks are now FIFO instead of LIFO;
284: - debug memory allocation subroutines are improved to run in multithreaded
285: programs;
286: - some memory leaks are fixed in process management (SPAWN and DETACH);
287: - version verification is added to shared objects;
288: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
289: linux (false mremap() prototype);
290: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 291: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.29 bertrand 292: - all '-' are replaced by '_' in random generator list;
1.28 bertrand 293: - minor memory leak is fixed in OPEN intrinsic (socket);
294: - major bug is fixed in IFERR structure. Only occurs in compiled program;
295: - major bug is fixed in copie_objet() and liberation(). Only concerns
296: format in FCH (file descriptor) and SCK (socket descriptor);
297: - debug routines are improved;
298: - PROCID is added;
299: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
300: and to not use swap;
1.26 bertrand 301: - major bug is fixed in sql support. SQL connections were closed in all chield
302: process;
303: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
304: discovered in Solaris thread safe allocators (libmalloc and libumem) that
305: are first fit class allocators. Solaris libmtmalloc works better and is
306: a best fit class allocator but its performance is poor than ptmalloc3
307: performance;
1.24 bertrand 308: - major bug is fixed in ROW+ intrinsic (new row was not added where it
309: should);
310: - minor bugs are fixed in interruptions.c (semaphores values when error is
311: caught);
312: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
313: created by SPAWN;
314: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
315: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 316: - ONEXIT is renamed in ATEXIT;
317: - ONEXIT new intrinsic is added.
1.20 bertrand 318: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
319: - major bug is fixed in static and shared variables initialization subroutine.
320: This bug only occurs when RPL/2 tries to create a shared or static variable
321: from an expression;
322: - major bug is fixed in copie_etat_processus(). A field that contains
323: information about shared variable was not copied to new processus structure;
1.19 bertrand 324: - some little memory leaks are fixed in evaluation(), recherche_type() and
325: sequenceur(). They only occured when syntax error were caught;
326: - IMPLICIT causes execution error instead system error;
327: - Hurd support is improved but currently broken because Hurd does not support
328: SIG_INFO. Work in progress;
329: - OpenBSD specific support is removed from sources;
330: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 331: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

366: Makefiles;
1.15 bertrand 367: - -a command line option analyzes program (structure and syntax) and
368: sends preprocessor output to standard output. This option is used by
369: rplc (RPL/2 compiler).
1.13 bertrand 370: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
371: - in formatted file, string format returned a variable length string even if
372: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 373: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 374: - keyed access files support is added. Currently, only formatted files are
375: supported;
376: - direct access files support is added. Currenlty, these files can only be used
377: in formatted mode;
378: - virtual variables are now writte in UTF-8 and all special characters
379: in string are escaped;

1.12 bertrand 382: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
383: each execution (md5 and sha1 sums) to enhance security. If one of these tools
384: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
385: on a non recoverable system error;
386: - openssl and sqlite3 libraries are added;
387: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
388: variable indicates RPL/2 root directory. If it is not set, root path
389: is given by configure script (d_exec_path);
1.11 bertrand 390: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

418: - TRIM, REPL and TOKENIZE are added;
419: - sockets options are now set before bind();
420: - shutdown() is added to all connected sockets;
421: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
422: list argument and inexistant elements).
423: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
424: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
425: signals sent to main process were not caught because DAEMON did not replace
426: old pid by new one;
427: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
428: evaluation when an error is reported from a subroutine in another subroutine.
429: For example, error was not caught in following program when it is executed with
430: -p option :
431: TEST << iferr TEST2 then end >>
432: TEST2 << 0 inv >>
433: - major bug is fixed in variable management. Some local variables were
434: seen as global ones;
435: - major bug is fixed in rplcore. Rplcore entered in dead lock when
436: script file contains a multibyte character;
437: - IN intrinsic is added;
438: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
439: returned false ;
440: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
441: programs;
442: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
443: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
444: strings were never closed;
445: - some bugs have been fixed in file management;

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

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

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

647: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
648: that all programs that worked with old SQL intrinsic can now work with
649: SQLQUERY. With all new programs, you can open a real connection to databases;
650: - NRPROC is added. This new intrinsic is used to catch error from child
651: process. Without NRPROC, any errors returned by child process cause
652: main process to abort;
653: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
654: starts a new process). There are no mutexes in RPL/2 because all spawned process
655: use specific context. Nevertheless, shared variables and associated mutexes
656: should be added;

743: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
744: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
745: workaround for this major bug. Nevertheless, all others capabilities seems to
746: work fine;
747: - '->' is modified to return error when program tries to initialiaze two
748: variables with the same name like

795: before starting interrupt evaluation;
796: - -f parameter is added when iconv is called;
797: - as old file program was bugged, a new option is added to configure script.
798: When configure is called with --disable-encoding-autodetection, make does not
799: try to detect source encoding. Please, do not use if RPL/2 can be built
800: without this option !
801: - new garbage collector (and more efficient) is written;

805: - -p option is added. With this option, all scripts are compiled before
806: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
807: 40% faster;
808: - read and write operations in pipe() are rewritten to be sure that such
809: operations are atomic;
810: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1004: With STATIC, next variables created by '->' are static;
1005: - PROTECT and UNPROTECT are added to protect variables against write
1006: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1007: versions of PROTECT and UNPROTECT that only deal with global variables

1009: - variable management routines have been rewritten. The new ones are
1010: uncompatible with the old ones. Before these changes, a local variable
1011: was exported to a child subroutine, but cannot be modified into this
1012: child subroutine. Now, a local variable is accessible only in its subroutine;
1013: - SAVE intrinsic is added to manipulate global variables;

1335: - NOT is not correctly formatted in formateur.c:
1336: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1337: with a NOTZ function !
1338: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1425: - PPAR and SPAR are written. SPAR returns a list that contains the
1426: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1427: statistical variable, or "DISABLED" if its type is not one of the type of
1428: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1429: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1430: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1431: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1432: disabled. Arguments of EXTERNAL are case sensitive because the external
1433: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1434: of known external functions but add the new list to the last. { "all" }
1435: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1436: external names of the known functions;
1437: - mkrplso.in is modified.
1438: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1452: VISIT does not find a name in level 1;
1453: - configure.in script is modified to add a new test (--enable-debug
1454: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1455: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1456: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1457: 'MATRIX' { 2 2 3 } GETR;
1458: - LOGSCALE intrinsic is improved and now, it can be used as
1459: { "main" "auxiliary" X Y } LOGSCALE;
1460: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1461: same than AXES:
1462: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1463: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1464: { { -10 10 } "automatic" } SCALE.
1465: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1466: because it changes only the dimension of the screen. To have a logarithmic
1467: scale, you must use LOGSCALE intrinsic:
1468: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1469: screen on second scale;
1470: - { X X } autoscale and { Y Y } logscale are now invalid;
1471: - *D is added (depth multiplication, for 3D graphics);
1472: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y

1490: in 0);
1491: - LAST is disabled in the main loop of DRAW intrinsic;
1492: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1493: evaluation of an equation, the system stack is returned corrupted to the
1494: sequencer;
1495: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1496: of a loop are not integer or real.
