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

1.52 bertrand 240: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
241: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
242: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
243: corruption. As internal memory management have been improved, a best fit
244: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 245: - gnuplot is upgraded to 4.4.1;
246: - deadlock is fixed in signal handlers: same mutex was used in standard
247: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
248: and signal handlers. A new signal handler specific mutex is added;
249: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
250: that has to be evaluated by ->NUM;
1.49 bertrand 251: - rplfile build process is modify to be sure that rplfile is not modified
252: after rpl build stage (to be sure that rplfile checksum is not modified after
253: rpl compilation);

255: modified to remove yacc code and renamed;
1.47 bertrand 256: - some workarounds have been written to not use buggy klibc SystemV IPCS.
257: ABORT now works on eComStation;
258: - sqlite is upgraded to 3.7.2;
259: - bug is fixed in software interrupts. When both process have different PID,
260: parent process was not interrupted if it is not group master process. To fix
261: this bug, SIGINJECT signal is not sent by child process but by control thread
262: in parent process;
1.46 bertrand 263: - minor bug is fixed in data injection (POKE) that does not work as expected
264: when child process is protected by NRPROC.
1.44 bertrand 265: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 266: - --enable-sysv-sems is added to configure script to use SystemV semaphores
267: functions instead of POSIX functions. This function is disabled or forced on
268: systems that does not provide correct POSIX or SysV semaphores subsystem;
269: - a dirty but not quick patch is written to workaround broken siginfo
270: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 271: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 272: (Unix PID);
1.41 bertrand 273: - some OpenBSD's hacks are added;
274: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 275: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

1.40 bertrand 279: or freeaddrinfo;
1.39 bertrand 280: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
281: - major bug is fixed in CHR intrinsic when obtained character is not printable;
282: - Lapack is upgraded to 3.2.2;
1.37 bertrand 283: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
1.36 bertrand 284: - TOKENIZE is now able to convert escape sequences;
285: - ATPOKE and CLRATPOKE new intrinsics are added;
286: - --enable-full-static configure flag is added. With this flag, mysql and
287: postgresql libraries are statically linked in rpl executable;

1.37 bertrand 289: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 290: - units is upgraded to 1.88;
291: - another major bug is fixed in the same variable creation subroutine.
292: Level 0 and 1 variables adresses were swapped when a global variable masked
293: a name of RPL/2 routine;
1.35 bertrand 294: - major bug is fixed in global variable creation subroutine. When a global
295: variable was created and when a local variable existed with the same name,
296: computed address of global variable was wrong;
297: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
298: is forced in front of all libraries.
1.34 bertrand 299: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
300: - BACKTRACE intrinsic is added;
301: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
302: when this structure is included in IFERR/THEN/END structure and when an error is
303: caught;
304: - major bug is fixed in analyse() subroutine. When evaluation() returned error
305: in a compiled program, analyse() caught this error twice and randomly aborted
306: with a segmentation error;
307: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
308: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
309: signals;
310: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
311: matrix.
1.33 bertrand 312: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

333: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
334: and to not use swap;
1.26 bertrand 335: - major bug is fixed in sql support. SQL connections were closed in all chield
336: process;
337: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
338: discovered in Solaris thread safe allocators (libmalloc and libumem) that
339: are first fit class allocators. Solaris libmtmalloc works better and is
340: a best fit class allocator but its performance is poor than ptmalloc3
341: performance;
1.24 bertrand 342: - major bug is fixed in ROW+ intrinsic (new row was not added where it
343: should);
344: - minor bugs are fixed in interruptions.c (semaphores values when error is
345: caught);
346: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
347: created by SPAWN;
348: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
349: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 350: - ONEXIT is renamed in ATEXIT;
351: - ONEXIT new intrinsic is added.

357: information about shared variable was not copied to new processus structure;
1.19 bertrand 358: - some little memory leaks are fixed in evaluation(), recherche_type() and
359: sequenceur(). They only occured when syntax error were caught;
360: - IMPLICIT causes execution error instead system error;
361: - Hurd support is improved but currently broken because Hurd does not support
362: SIG_INFO. Work in progress;
363: - OpenBSD specific support is removed from sources;
364: - support for Mac OS X and Windows/Cygwin is added.

457: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
458: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
459: signals sent to main process were not caught because DAEMON did not replace
460: old pid by new one;
461: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
462: evaluation when an error is reported from a subroutine in another subroutine.
463: For example, error was not caught in following program when it is executed with

470: script file contains a multibyte character;
471: - IN intrinsic is added;
472: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
473: returned false ;
474: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
475: programs;
476: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
477: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
478: strings were never closed;
479: - some bugs have been fixed in file management;

494: - fprintf is replaced by some functions that allow transliterations between
495: locales;
496: - '"' can now be used in strings ("\"");
497: - iconv is called with -c in preprocessor stage. It is done to write

499: - double free is fixed in liberation() (type SQL, only occurs when locale is
500: set);
501: - LOCALIZATION, UCASE and LCASE are added;

511: - pipe() is overwritten by a macro to avoid a system error. Communication
512: between process are done with pipes and these pipes are managed by a
513: specific asynchrone thread. If a script try to create more threads than
514: management thread can destroy, you can quickly achieve maximum number of
515: opened files and pipe() shall return a system error. This macro tries to create
516: pipes. If pipe() function returns an error, macro waits and retries. If
517: number of retries is greater than a hardcoded value, macro returns an error;
518: - major bug (deadlock) is fixed in process and thread management. I hope
519: this bug shall be the last one;

525: - some bugfixes are added in process management;
526: - all process management is rewritten to avoid usage of defunct process
527: or thread number;
528: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
529: was called before a pending interruption5 (SIGFSTOP), signal handler uses
530: a freed semaphore and corrupts heap;
531: - CLRERR is added to erase previous errors;
532: - ERRN and ERRM return exception message and number;
533: - major bug is fixed in interruptions.c. All signal are now bufferised
534: when semaphore_liste_threads is null to avoid deadlock. This bug only
535: occured when STOP was sent to a dying thread or process (when this thread or
536: process was running retrait_thread());
537: - matrix rank is computed before matrix inversion;
538: - file locks are added to stdin and stdout. stderr is not locked because
539: all messages written by signal handlers are sent to stderr;
540: - configure.in script is modified to test gcc version and avoid a bug in

614: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
615: process is killed;
616: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
617: know typeof() intrinsic function. This function is not standard but exists

682: that all programs that worked with old SQL intrinsic can now work with
683: SQLQUERY. With all new programs, you can open a real connection to databases;
684: - NRPROC is added. This new intrinsic is used to catch error from child
685: process. Without NRPROC, any errors returned by child process cause
686: main process to abort;
687: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
688: starts a new process). There are no mutexes in RPL/2 because all spawned process
689: use specific context. Nevertheless, shared variables and associated mutexes
690: should be added;

1465: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1466: disabled. Arguments of EXTERNAL are case sensitive because the external
1467: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1468: of known external functions but add the new list to the last. { "all" }
1469: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1470: external names of the known functions;
1471: - mkrplso.in is modified.
1472: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1473: - vim syntax file is upgraded;
1474: - a minor mistake is fixed in recherche_instruction_suivante();
1475: - some minor memory leaks are fixed in recherche_type() function. They only
1476: occurs when a syntax error is detected;
1477: - #error and #warning preprocessor macros are added;
1478: - INCR and DECR are written (with integer or variable argument);
1479: - CSWP and RSWP are added and tested;
1480: - a minor bug is fixed in analyse.c;
1481: - DEBIAN/control is added to build debian package;
1482: - SCALE is fixed and improved ("automatic" keyword);
1483: - PUTC and PUTR new intrinsics are added.
1484: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1485: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1486: VISIT does not find a name in level 1;
1487: - configure.in script is modified to add a new test (--enable-debug
1488: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1489: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1490: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1491: 'MATRIX' { 2 2 3 } GETR;
1492: - LOGSCALE intrinsic is improved and now, it can be used as
1493: { "main" "auxiliary" X Y } LOGSCALE;
1494: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1495: same than AXES:
1496: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1497: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1498: { { -10 10 } "automatic" } SCALE.
1499: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1500: because it changes only the dimension of the screen. To have a logarithmic
1501: scale, you must use LOGSCALE intrinsic:
1502: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1503: screen on second scale;
1504: - { X X } autoscale and { Y Y } logscale are now invalid;
1505: - *D is added (depth multiplication, for 3D graphics);
1506: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1507: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1508: - a major bug is fixed in GETI instrinsic when it is used with a name
1509: that contains a matrix or a vector (bad upper bounds conditions in
1510: incrementation);
1511: - DISP intrinsic now uses the 33-th flag. When it is not set
1512: (default), a final carriage return is sent to the terminal;
1513: - AXES intrinsic only takes a list that can contains the keywork
1514: "main" or "auxiliary". Before this modification, this keyword was in
1515: the first stack level;
1516: - vim syntax file is upgraded;
1517: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1518: option;
1519: - LAST is now disabled in the main loop of INT intrinsic;
1520: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1521: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1522: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1523: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1524: in 0);
1525: - LAST is disabled in the main loop of DRAW intrinsic;
1526: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1527: evaluation of an equation, the system stack is returned corrupted to the
1528: sequencer;
1529: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1530: of a loop are not integer or real.
1531: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1533: have the same name. To improve the compilation() subroutine, I have to
1534: add some tests in gestion_variables.c;
1535: - recherche_type() subroutine ad some other connex subroutines are improved.
1536: Now, some syntax errors about object are caught and do not perform sequencer
1537: hangup;

1539: - Makefile.am's and configure.in scripts are improved.
1540: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1541: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1542: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1562: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1563: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1564: is a quick and dirty workaround...);
1565: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1566: - rplconvert is improved.
