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

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

256: parent process was not interrupted if it is not group master process. To fix
257: this bug, SIGINJECT signal is not sent by child process but by control thread
258: in parent process;
259: - minor bug is fixed in data injection (POKE) that does not work as expected
260: when child process is protected by NRPROC.
261: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
262: - --enable-sysv-sems is added to configure script to use SystemV semaphores
263: functions instead of POSIX functions. This function is disabled or forced on
264: systems that does not provide correct POSIX or SysV semaphores subsystem;
265: - a dirty but not quick patch is written to workaround broken siginfo
266: structures. This patch has been successfully tested. It uses a segment of
267: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
268: (Unix PID);
269: - some OpenBSD's hacks are added;
270: - broken siginfo->si_pid field is now checked by configure script;

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

296: - BACKTRACE intrinsic is added;
297: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
298: when this structure is included in IFERR/THEN/END structure and when an error is
299: caught;
300: - major bug is fixed in analyse() subroutine. When evaluation() returned error
301: in a compiled program, analyse() caught this error twice and randomly aborted
302: with a segmentation error;
303: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
304: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
305: signals;
306: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
307: matrix.

326: format in FCH (file descriptor) and SCK (socket descriptor);
327: - debug routines are improved;
328: - PROCID is added;
329: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
330: and to not use swap;
331: - major bug is fixed in sql support. SQL connections were closed in all chield
332: process;
333: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
334: discovered in Solaris thread safe allocators (libmalloc and libumem) that
335: are first fit class allocators. Solaris libmtmalloc works better and is
336: a best fit class allocator but its performance is poor than ptmalloc3
337: performance;
338: - major bug is fixed in ROW+ intrinsic (new row was not added where it
339: should);
340: - minor bugs are fixed in interruptions.c (semaphores values when error is
341: caught);
342: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
343: created by SPAWN;

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

399: rplc (RPL/2 compiler).
400: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
401: - in formatted file, string format returned a variable length string even if
402: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
403: a variable length string and 'CHARACTER*(n)' a fixed length string;
404: - keyed access files support is added. Currently, only formatted files are
405: supported;
406: - direct access files support is added. Currenlty, these files can only be used
407: in formatted mode;

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

453: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
454: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
455: signals sent to main process were not caught because DAEMON did not replace
456: old pid by new one;
457: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
458: evaluation when an error is reported from a subroutine in another subroutine.
459: For example, error was not caught in following program when it is executed with
460: -p option :
461: TEST << iferr TEST2 then end >>
462: TEST2 << 0 inv >>
463: - major bug is fixed in variable management. Some local variables were
464: seen as global ones;

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

477: - major bug is fixed in -A command line option (NULL character is missing);
478: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
479: made by blocks (1024 bytes). When an incomplete multibyte sequence is
480: encountered at end of block, subroutine aborts with an execution error;
481: - major bug is fixed in OPEN (TCP/IPv4 sockets).
482: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
483: - DISP now locks stdout;
484: - rpliconv is added to replace standard iconv provided by operating system.
485: Indeed, conversion between different encodages requires transliteration
486: that is not offered by some iconv utility;
487: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
488: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
489: not be found), SYSEVAL enters in a dead lock;
490: - fprintf is replaced by some functions that allow transliterations between
491: locales;
492: - '"' can now be used in strings ("\"");
493: - iconv is called with -c in preprocessor stage. It is done to write
494: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
495: - double free is fixed in liberation() (type SQL, only occurs when locale is
496: set);
497: - LOCALIZATION, UCASE and LCASE are added;
498: - major bug is fixed in EXIT intrinsic that was able to return a false
499: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);

507: - pipe() is overwritten by a macro to avoid a system error. Communication
508: between process are done with pipes and these pipes are managed by a
509: specific asynchrone thread. If a script try to create more threads than
510: management thread can destroy, you can quickly achieve maximum number of
511: opened files and pipe() shall return a system error. This macro tries to create
512: pipes. If pipe() function returns an error, macro waits and retries. If
513: number of retries is greater than a hardcoded value, macro returns an error;
514: - major bug (deadlock) is fixed in process and thread management. I hope
515: this bug shall be the last one;
516: - major bug is fixed in DET intrinsic (determinant was computed without LU
517: diagonalization);
518: - SWAPCNTXT is added;
519: - minor bug is fixed in Makefile.am (licences rule).

521: - some bugfixes are added in process management;
522: - all process management is rewritten to avoid usage of defunct process
523: or thread number;
524: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
525: was called before a pending interruption5 (SIGFSTOP), signal handler uses
526: a freed semaphore and corrupts heap;
527: - CLRERR is added to erase previous errors;
528: - ERRN and ERRM return exception message and number;
529: - major bug is fixed in interruptions.c. All signal are now bufferised
530: when semaphore_liste_threads is null to avoid deadlock. This bug only
531: occured when STOP was sent to a dying thread or process (when this thread or
532: process was running retrait_thread());
533: - matrix rank is computed before matrix inversion;
534: - file locks are added to stdin and stdout. stderr is not locked because
535: all messages written by signal handlers are sent to stderr;
536: - configure.in script is modified to test gcc version and avoid a bug in
537: gcc older than 4.4;
538: - some benchmarks have been done :

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

657: static variable that is shared by multiple threads;
658: - '->' intrinsic is improved. All object copies have been avoided;
659: - -n flag is added to catch HUP signal. stderr and stdout are redirected
660: to a file, stdin is redirected to /dev/null when control process is killed;
661: - a mutex is added to each object (before this modification,

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

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

835: - -p option is added. With this option, all scripts are compiled before
836: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
837: 40% faster;
838: - read and write operations in pipe() are rewritten to be sure that such
839: operations are atomic;
840: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1036: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1037: versions of PROTECT and UNPROTECT that only deal with global variables
1038: (see RCL/SAVE);
1039: - variable management routines have been rewritten. The new ones are
1040: uncompatible with the old ones. Before these changes, a local variable
1041: was exported to a child subroutine, but cannot be modified into this
1042: child subroutine. Now, a local variable is accessible only in its subroutine;
1043: - SAVE intrinsic is added to manipulate global variables;

1365: - NOT is not correctly formatted in formateur.c:
1366: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1367: with a NOTZ function !
1368: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1371: - RPL/2 is tested with efence and valgrind;
1372: - configure.in script is modified;
1373: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1455: - PPAR and SPAR are written. SPAR returns a list that contains the
1456: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1457: statistical variable, or "DISABLED" if its type is not one of the type of
1458: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1459: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1460: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1461: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1462: disabled. Arguments of EXTERNAL are case sensitive because the external
1463: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1464: of known external functions but add the new list to the last. { "all" }
1465: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1466: external names of the known functions;
1467: - mkrplso.in is modified.
1468: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1469: - vim syntax file is upgraded;
1470: - a minor mistake is fixed in recherche_instruction_suivante();

1481: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1482: VISIT does not find a name in level 1;
1483: - configure.in script is modified to add a new test (--enable-debug
1484: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1485: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1486: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1487: 'MATRIX' { 2 2 3 } GETR;
1488: - LOGSCALE intrinsic is improved and now, it can be used as
1489: { "main" "auxiliary" X Y } LOGSCALE;
1490: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1491: same than AXES:
1492: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1493: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1494: { { -10 10 } "automatic" } SCALE.
1495: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1496: because it changes only the dimension of the screen. To have a logarithmic
1497: scale, you must use LOGSCALE intrinsic:
1498: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1499: screen on second scale;
1500: - { X X } autoscale and { Y Y } logscale are now invalid;
1501: - *D is added (depth multiplication, for 3D graphics);
1502: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1503: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1504: - a major bug is fixed in GETI instrinsic when it is used with a name
1505: that contains a matrix or a vector (bad upper bounds conditions in
1506: incrementation);
1507: - DISP intrinsic now uses the 33-th flag. When it is not set
1508: (default), a final carriage return is sent to the terminal;
1509: - AXES intrinsic only takes a list that can contains the keywork
1510: "main" or "auxiliary". Before this modification, this keyword was in
1511: the first stack level;
1512: - vim syntax file is upgraded;
1513: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
