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

204: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
205: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
206: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
207: corruption. As internal memory management have been improved, a best fit
208: allocator like ptmalloc3 is not required anymore;
209: - gnuplot is upgraded to 4.4.1;
210: - deadlock is fixed in signal handlers: same mutex was used in standard
211: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
212: and signal handlers. A new signal handler specific mutex is added;
213: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
214: that has to be evaluated by ->NUM;
215: - rplfile build process is modify to be sure that rplfile is not modified
216: after rpl build stage (to be sure that rplfile checksum is not modified after
217: rpl compilation);
218: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
219: modified to remove yacc code and renamed;

221: ABORT now works on eComStation;
222: - sqlite is upgraded to 3.7.2;
223: - bug is fixed in software interrupts. When both process have different PID,
224: parent process was not interrupted if it is not group master process. To fix
225: this bug, SIGINJECT signal is not sent by child process but by control thread
226: in parent process;
227: - minor bug is fixed in data injection (POKE) that does not work as expected
228: when child process is protected by NRPROC.
229: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
230: - --enable-sysv-sems is added to configure script to use SystemV semaphores
231: functions instead of POSIX functions. This function is disabled or forced on
232: systems that does not provide correct POSIX or SysV semaphores subsystem;
233: - a dirty but not quick patch is written to workaround broken siginfo
234: structures. This patch has been successfully tested. It uses a segment of
235: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
236: (Unix PID);
237: - some OpenBSD's hacks are added;
238: - broken siginfo->si_pid field is now checked by configure script;
239: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

247: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
248: - TOKENIZE is now able to convert escape sequences;
249: - ATPOKE and CLRATPOKE new intrinsics are added;
250: - --enable-full-static configure flag is added. With this flag, mysql and
251: postgresql libraries are statically linked in rpl executable;
252: - units Makefile is modified to avoid readline and ncurses usages;
253: - sqlite is upgraded to 3.7.0.1;
254: - units is upgraded to 1.88;
255: - another major bug is fixed in the same variable creation subroutine.
256: Level 0 and 1 variables adresses were swapped when a global variable masked
257: a name of RPL/2 routine;
258: - major bug is fixed in global variable creation subroutine. When a global
259: variable was created and when a local variable existed with the same name,
260: computed address of global variable was wrong;
261: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
262: is forced in front of all libraries.
263: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
264: - BACKTRACE intrinsic is added;
265: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
266: when this structure is included in IFERR/THEN/END structure and when an error is
267: caught;
268: - major bug is fixed in analyse() subroutine. When evaluation() returned error
269: in a compiled program, analyse() caught this error twice and randomly aborted
270: with a segmentation error;
271: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
272: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
273: signals;
274: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
275: matrix.
276: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
277: - minor bug is fixed in evaluation() subroutine. With this patch, same program
278: returns same result with or without -p flag;

280: - openssl is upgraded to 1.0.0a;
281: - interrupt stacks are now FIFO instead of LIFO;
282: - debug memory allocation subroutines are improved to run in multithreaded
283: programs;
284: - some memory leaks are fixed in process management (SPAWN and DETACH);
285: - version verification is added to shared objects;
286: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
287: linux (false mremap() prototype);
288: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
289: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
290: - all '-' are replaced by '_' in random generator list;
291: - minor memory leak is fixed in OPEN intrinsic (socket);

293: - major bug is fixed in copie_objet() and liberation(). Only concerns
294: format in FCH (file descriptor) and SCK (socket descriptor);
295: - debug routines are improved;
296: - PROCID is added;
297: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
298: and to not use swap;
299: - major bug is fixed in sql support. SQL connections were closed in all chield
300: process;
301: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
302: discovered in Solaris thread safe allocators (libmalloc and libumem) that
303: are first fit class allocators. Solaris libmtmalloc works better and is
304: a best fit class allocator but its performance is poor than ptmalloc3
305: performance;
306: - major bug is fixed in ROW+ intrinsic (new row was not added where it
307: should);
308: - minor bugs are fixed in interruptions.c (semaphores values when error is
309: caught);
310: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
311: created by SPAWN;

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

377: in string are escaped;
378: - all formatted files are now converted into UTF-8;
379: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
380: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
381: each execution (md5 and sha1 sums) to enhance security. If one of these tools
382: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
383: on a non recoverable system error;
384: - openssl and sqlite3 libraries are added;
385: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

421: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
422: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
423: signals sent to main process were not caught because DAEMON did not replace
424: old pid by new one;
425: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
426: evaluation when an error is reported from a subroutine in another subroutine.
427: For example, error was not caught in following program when it is executed with
428: -p option :
429: TEST << iferr TEST2 then end >>
430: TEST2 << 0 inv >>
431: - major bug is fixed in variable management. Some local variables were
432: seen as global ones;

434: script file contains a multibyte character;
435: - IN intrinsic is added;
436: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
437: returned false ;
438: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
439: programs;
440: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
441: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
442: strings were never closed;
443: - some bugs have been fixed in file management;

445: - major bug is fixed in -A command line option (NULL character is missing);
446: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
447: made by blocks (1024 bytes). When an incomplete multibyte sequence is
448: encountered at end of block, subroutine aborts with an execution error;
449: - major bug is fixed in OPEN (TCP/IPv4 sockets).
450: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
451: - DISP now locks stdout;
452: - rpliconv is added to replace standard iconv provided by operating system.
453: Indeed, conversion between different encodages requires transliteration
454: that is not offered by some iconv utility;
455: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
456: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
457: not be found), SYSEVAL enters in a dead lock;
458: - fprintf is replaced by some functions that allow transliterations between
459: locales;
460: - '"' can now be used in strings ("\"");
461: - iconv is called with -c in preprocessor stage. It is done to write
462: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
463: - double free is fixed in liberation() (type SQL, only occurs when locale is
464: set);
465: - LOCALIZATION, UCASE and LCASE are added;
466: - major bug is fixed in EXIT intrinsic that was able to return a false
467: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);

469: used in onLoading from shared library, USE was pushed on stack as algebraic
470: expression;
471: - libiconv is upgraded to 1.13.1;
472: - gnuplot is upgraded to 4.2.6;
473: - gsl is upgraded to 1.13.
474: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
475: - pipe() is overwritten by a macro to avoid a system error. Communication
476: between process are done with pipes and these pipes are managed by a
477: specific asynchrone thread. If a script try to create more threads than
478: management thread can destroy, you can quickly achieve maximum number of
479: opened files and pipe() shall return a system error. This macro tries to create
480: pipes. If pipe() function returns an error, macro waits and retries. If
481: number of retries is greater than a hardcoded value, macro returns an error;
482: - major bug (deadlock) is fixed in process and thread management. I hope
483: this bug shall be the last one;
484: - major bug is fixed in DET intrinsic (determinant was computed without LU
485: diagonalization);
486: - SWAPCNTXT is added;
487: - minor bug is fixed in Makefile.am (licences rule).

489: - some bugfixes are added in process management;
490: - all process management is rewritten to avoid usage of defunct process
491: or thread number;
492: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
493: was called before a pending interruption5 (SIGFSTOP), signal handler uses
494: a freed semaphore and corrupts heap;
495: - CLRERR is added to erase previous errors;
496: - ERRN and ERRM return exception message and number;
497: - major bug is fixed in interruptions.c. All signal are now bufferised
498: when semaphore_liste_threads is null to avoid deadlock. This bug only
499: occured when STOP was sent to a dying thread or process (when this thread or
500: process was running retrait_thread());
501: - matrix rank is computed before matrix inversion;
502: - file locks are added to stdin and stdout. stderr is not locked because
503: all messages written by signal handlers are sent to stderr;
504: - configure.in script is modified to test gcc version and avoid a bug in
505: gcc older than 4.4;

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

647: SQLQUERY. With all new programs, you can open a real connection to databases;
648: - NRPROC is added. This new intrinsic is used to catch error from child
649: process. Without NRPROC, any errors returned by child process cause
650: main process to abort;
651: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
652: starts a new process). There are no mutexes in RPL/2 because all spawned process
653: use specific context. Nevertheless, shared variables and associated mutexes

798: without this option !
799: - new garbage collector (and more efficient) is written;
800: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does

1002: With STATIC, next variables created by '->' are static;
1003: - PROTECT and UNPROTECT are added to protect variables against write
1004: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1005: versions of PROTECT and UNPROTECT that only deal with global variables
1006: (see RCL/SAVE);
1007: - variable management routines have been rewritten. The new ones are
1008: uncompatible with the old ones. Before these changes, a local variable
1009: was exported to a child subroutine, but cannot be modified into this
1010: child subroutine. Now, a local variable is accessible only in its subroutine;
1011: - SAVE intrinsic is added to manipulate global variables;

1333: - NOT is not correctly formatted in formateur.c:
1334: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1335: with a NOTZ function !
1336: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1339: - RPL/2 is tested with efence and valgrind;
1340: - configure.in script is modified;
1341: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1402: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1403: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1404: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

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

1450: VISIT does not find a name in level 1;
1451: - configure.in script is modified to add a new test (--enable-debug
1452: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1453: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1454: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1455: 'MATRIX' { 2 2 3 } GETR;
1456: - LOGSCALE intrinsic is improved and now, it can be used as
1457: { "main" "auxiliary" X Y } LOGSCALE;
1458: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1459: same than AXES:
1460: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1461: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1462: { { -10 10 } "automatic" } SCALE.
1463: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1464: because it changes only the dimension of the screen. To have a logarithmic
1465: scale, you must use LOGSCALE intrinsic:
1466: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1467: screen on second scale;
1468: - { X X } autoscale and { Y Y } logscale are now invalid;
1469: - *D is added (depth multiplication, for 3D graphics);
1470: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1471: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1472: - a major bug is fixed in GETI instrinsic when it is used with a name
1473: that contains a matrix or a vector (bad upper bounds conditions in
1474: incrementation);
1475: - DISP intrinsic now uses the 33-th flag. When it is not set
1476: (default), a final carriage return is sent to the terminal;
1477: - AXES intrinsic only takes a list that can contains the keywork
1478: "main" or "auxiliary". Before this modification, this keyword was in
1479: the first stack level;
1480: - vim syntax file is upgraded;
1481: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1482: option;
1483: - LAST is now disabled in the main loop of INT intrinsic;
1484: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1485: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1486: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1487: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1488: in 0);
1489: - LAST is disabled in the main loop of DRAW intrinsic;
1490: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1491: evaluation of an equation, the system stack is returned corrupted to the
1492: sequencer;
1493: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1494: of a loop are not integer or real.
1495: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1503: - Makefile.am's and configure.in scripts are improved.
1504: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1505: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1506: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1508: - recherche_type() is rewritten to be faster;
1509: - gsl is upgraded (release 1.3);
