145: by a new feature in glibc.
146: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
147: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
148: "ALL" IMPLICIT when it runs in interactive mode;
149: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
150: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
151: to use SAVE to manipulate global variables;
152: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
153: subroutines;
154: - fix major memory access violation in evaluation subroutine. Only occurs
155: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
156: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
157: when X was a vector or a table.

187: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
188: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
189: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
190: corruption. As internal memory management have been improved, a best fit
191: allocator like ptmalloc3 is not required anymore;
192: - gnuplot is upgraded to 4.4.1;
193: - deadlock is fixed in signal handlers: same mutex was used in standard
194: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
195: and signal handlers. A new signal handler specific mutex is added;
196: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
197: that has to be evaluated by ->NUM;
198: - rplfile build process is modify to be sure that rplfile is not modified
199: after rpl build stage (to be sure that rplfile checksum is not modified after

207: parent process was not interrupted if it is not group master process. To fix
208: this bug, SIGINJECT signal is not sent by child process but by control thread
209: in parent process;
210: - minor bug is fixed in data injection (POKE) that does not work as expected
211: when child process is protected by NRPROC.
212: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
213: - --enable-sysv-sems is added to configure script to use SystemV semaphores
214: functions instead of POSIX functions. This function is disabled or forced on
215: systems that does not provide correct POSIX or SysV semaphores subsystem;
216: - a dirty but not quick patch is written to workaround broken siginfo
217: structures. This patch has been successfully tested. It uses a segment of
218: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
219: (Unix PID);
220: - some OpenBSD's hacks are added;
221: - broken siginfo->si_pid field is now checked by configure script;
222: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

231: - TOKENIZE is now able to convert escape sequences;
232: - ATPOKE and CLRATPOKE new intrinsics are added;
233: - --enable-full-static configure flag is added. With this flag, mysql and
234: postgresql libraries are statically linked in rpl executable;

236: - sqlite is upgraded to 3.7.0.1;
237: - units is upgraded to 1.88;
238: - another major bug is fixed in the same variable creation subroutine.
239: Level 0 and 1 variables adresses were swapped when a global variable masked
240: a name of RPL/2 routine;
241: - major bug is fixed in global variable creation subroutine. When a global
242: variable was created and when a local variable existed with the same name,
243: computed address of global variable was wrong;
244: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
245: is forced in front of all libraries.
246: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
247: - BACKTRACE intrinsic is added;
248: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
249: when this structure is included in IFERR/THEN/END structure and when an error is
250: caught;
251: - major bug is fixed in analyse() subroutine. When evaluation() returned error
252: in a compiled program, analyse() caught this error twice and randomly aborted
253: with a segmentation error;
254: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
255: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
256: signals;
257: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
258: matrix.
259: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
260: - minor bug is fixed in evaluation() subroutine. With this patch, same program
261: returns same result with or without -p flag;

265: - debug memory allocation subroutines are improved to run in multithreaded
266: programs;
267: - some memory leaks are fixed in process management (SPAWN and DETACH);
268: - version verification is added to shared objects;
269: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
270: linux (false mremap() prototype);
271: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
272: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
273: - all '-' are replaced by '_' in random generator list;

277: format in FCH (file descriptor) and SCK (socket descriptor);
278: - debug routines are improved;
279: - PROCID is added;
280: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
281: and to not use swap;
282: - major bug is fixed in sql support. SQL connections were closed in all chield
283: process;
284: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
285: discovered in Solaris thread safe allocators (libmalloc and libumem) that
286: are first fit class allocators. Solaris libmtmalloc works better and is
287: a best fit class allocator but its performance is poor than ptmalloc3
288: performance;
289: - major bug is fixed in ROW+ intrinsic (new row was not added where it
290: should);
291: - minor bugs are fixed in interruptions.c (semaphores values when error is
292: caught);
293: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
294: created by SPAWN;
295: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute

304: information about shared variable was not copied to new processus structure;
305: - some little memory leaks are fixed in evaluation(), recherche_type() and
306: sequenceur(). They only occured when syntax error were caught;
307: - IMPLICIT causes execution error instead system error;
308: - Hurd support is improved but currently broken because Hurd does not support
309: SIG_INFO. Work in progress;
310: - OpenBSD specific support is removed from sources;
311: - support for Mac OS X and Windows/Cygwin is added.

363: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
364: each execution (md5 and sha1 sums) to enhance security. If one of these tools
365: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
366: on a non recoverable system error;
367: - openssl and sqlite3 libraries are added;
368: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

396: Number of scalar operations per second and per core : 2383016
397:
398: - PULPRFL does not abort on BUG() but on execution error;
399: - TRIM, REPL and TOKENIZE are added;
400: - sockets options are now set before bind();
401: - shutdown() is added to all connected sockets;
402: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
403: list argument and inexistant elements).
404: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
405: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
406: signals sent to main process were not caught because DAEMON did not replace
407: old pid by new one;
408: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
409: evaluation when an error is reported from a subroutine in another subroutine.
410: For example, error was not caught in following program when it is executed with
411: -p option :
412: TEST << iferr TEST2 then end >>
413: TEST2 << 0 inv >>
414: - major bug is fixed in variable management. Some local variables were
415: seen as global ones;
416: - major bug is fixed in rplcore. Rplcore entered in dead lock when
417: script file contains a multibyte character;
418: - IN intrinsic is added;
419: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
420: returned false ;
421: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
422: programs;
423: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
424: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
425: strings were never closed;
426: - some bugs have been fixed in file management;
427: - RPL/2 can now be run on EBCDIC systems (OS/390);
428: - major bug is fixed in -A command line option (NULL character is missing);
429: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
430: made by blocks (1024 bytes). When an incomplete multibyte sequence is
431: encountered at end of block, subroutine aborts with an execution error;
432: - major bug is fixed in OPEN (TCP/IPv4 sockets).
433: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
434: - DISP now locks stdout;
435: - rpliconv is added to replace standard iconv provided by operating system.
436: Indeed, conversion between different encodages requires transliteration
437: that is not offered by some iconv utility;
438: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
439: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
440: not be found), SYSEVAL enters in a dead lock;
441: - fprintf is replaced by some functions that allow transliterations between
442: locales;
443: - '"' can now be used in strings ("\"");
444: - iconv is called with -c in preprocessor stage. It is done to write
445: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
446: - double free is fixed in liberation() (type SQL, only occurs when locale is
447: set);
448: - LOCALIZATION, UCASE and LCASE are added;
449: - major bug is fixed in EXIT intrinsic that was able to return a false
450: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
451: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
452: used in onLoading from shared library, USE was pushed on stack as algebraic
453: expression;
454: - libiconv is upgraded to 1.13.1;
455: - gnuplot is upgraded to 4.2.6;
456: - gsl is upgraded to 1.13.
457: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
458: - pipe() is overwritten by a macro to avoid a system error. Communication
459: between process are done with pipes and these pipes are managed by a
460: specific asynchrone thread. If a script try to create more threads than
461: management thread can destroy, you can quickly achieve maximum number of
462: opened files and pipe() shall return a system error. This macro tries to create
463: pipes. If pipe() function returns an error, macro waits and retries. If
464: number of retries is greater than a hardcoded value, macro returns an error;
465: - major bug (deadlock) is fixed in process and thread management. I hope
466: this bug shall be the last one;
467: - major bug is fixed in DET intrinsic (determinant was computed without LU
468: diagonalization);
469: - SWAPCNTXT is added;
470: - minor bug is fixed in Makefile.am (licences rule).
471: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
472: - some bugfixes are added in process management;
473: - all process management is rewritten to avoid usage of defunct process
474: or thread number;
475: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
476: was called before a pending interruption5 (SIGFSTOP), signal handler uses
477: a freed semaphore and corrupts heap;
478: - CLRERR is added to erase previous errors;
479: - ERRN and ERRM return exception message and number;
480: - major bug is fixed in interruptions.c. All signal are now bufferised
481: when semaphore_liste_threads is null to avoid deadlock. This bug only
482: occured when STOP was sent to a dying thread or process (when this thread or
483: process was running retrait_thread());
484: - matrix rank is computed before matrix inversion;
485: - file locks are added to stdin and stdout. stderr is not locked because
486: all messages written by signal handlers are sent to stderr;
487: - configure.in script is modified to test gcc version and avoid a bug in
488: gcc older than 4.4;
489: - some benchmarks have been done :

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

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

629: that all programs that worked with old SQL intrinsic can now work with
630: SQLQUERY. With all new programs, you can open a real connection to databases;
631: - NRPROC is added. This new intrinsic is used to catch error from child
632: process. Without NRPROC, any errors returned by child process cause
633: main process to abort;
634: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
635: starts a new process). There are no mutexes in RPL/2 because all spawned process
636: use specific context. Nevertheless, shared variables and associated mutexes
637: should be added;

985: With STATIC, next variables created by '->' are static;
986: - PROTECT and UNPROTECT are added to protect variables against write
987: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
988: versions of PROTECT and UNPROTECT that only deal with global variables
989: (see RCL/SAVE);
990: - variable management routines have been rewritten. The new ones are
991: uncompatible with the old ones. Before these changes, a local variable
992: was exported to a child subroutine, but cannot be modified into this
993: child subroutine. Now, a local variable is accessible only in its subroutine;
994: - SAVE intrinsic is added to manipulate global variables;

1316: - NOT is not correctly formatted in formateur.c:
1317: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1318: with a NOTZ function !
1319: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1322: - RPL/2 is tested with efence and valgrind;
1323: - configure.in script is modified;
1324: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1385: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1386: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1387: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1404: - SCLS is added;
1405: - DRWS now uses COLS to draw 2D graphics;
1406: - PPAR and SPAR are written. SPAR returns a list that contains the
1407: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1408: statistical variable, or "DISABLED" if its type is not one of the type of
1409: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1410: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1411: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1412: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1413: disabled. Arguments of EXTERNAL are case sensitive because the external
1414: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1415: of known external functions but add the new list to the last. { "all" }
1416: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1417: external names of the known functions;
1418: - mkrplso.in is modified.
1419: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1420: - vim syntax file is upgraded;
1421: - a minor mistake is fixed in recherche_instruction_suivante();

1432: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1433: VISIT does not find a name in level 1;
1434: - configure.in script is modified to add a new test (--enable-debug
1435: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1436: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1437: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1438: 'MATRIX' { 2 2 3 } GETR;
1439: - LOGSCALE intrinsic is improved and now, it can be used as
1440: { "main" "auxiliary" X Y } LOGSCALE;
1441: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1442: same than AXES:
1443: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1444: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1445: { { -10 10 } "automatic" } SCALE.
1446: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1447: because it changes only the dimension of the screen. To have a logarithmic
1448: scale, you must use LOGSCALE intrinsic:
1449: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1450: screen on second scale;
1451: - { X X } autoscale and { Y Y } logscale are now invalid;
1452: - *D is added (depth multiplication, for 3D graphics);
1453: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1454: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1455: - a major bug is fixed in GETI instrinsic when it is used with a name
1456: that contains a matrix or a vector (bad upper bounds conditions in
1457: incrementation);
1458: - DISP intrinsic now uses the 33-th flag. When it is not set
1459: (default), a final carriage return is sent to the terminal;
1460: - AXES intrinsic only takes a list that can contains the keywork
1461: "main" or "auxiliary". Before this modification, this keyword was in
1462: the first stack level;
1463: - vim syntax file is upgraded;
1464: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1465: option;
1466: - LAST is now disabled in the main loop of INT intrinsic;
1467: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1468: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1469: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1470: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1471: in 0);
1472: - LAST is disabled in the main loop of DRAW intrinsic;
1473: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1474: evaluation of an equation, the system stack is returned corrupted to the
1475: sequencer;
1476: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1477: of a loop are not integer or real.
1478: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1479: - the compilation stage aborts with an error message when two definitions
1480: have the same name. To improve the compilation() subroutine, I have to
1481: add some tests in gestion_variables.c;
1482: - recherche_type() subroutine ad some other connex subroutines are improved.
1483: Now, some syntax errors about object are caught and do not perform sequencer
1484: hangup;
1485: - readline is upgraded (minor compilation bug with recent gcc);
1486: - Makefile.am's and configure.in scripts are improved.
1487: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1488: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1489: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1490: the boxwidth, 1 by default);
1491: - recherche_type() is rewritten to be faster;
1492: - gsl is upgraded (release 1.3);
1493: - ncurses is upgraded and patched (release 5.3);
1494: - recherche_instruction_suivante() is fixed (string research with included
1495: '"') and rewritten to be faster;
1496: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1497: segfault.
1498: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)
