1: * Tue Dec 18 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.13 (RPL/2)
2: - major bug (segfault) is fixed in liste_variables(). It only occurs
3: when this function is called with shared variables;
4: - all internal data are now stored in 64 bits wide integers (even is 32 bits
5: ABI is selected);
6: - major bug is fixed in recherche_instruction_suivante(). In some
7: circumstances, this function can return a spurious error;
8: - new NATIVE*(*) data format is added. By default, native*(*) is used
9: to write data without precision loss. It can also be used to write
10: complex objects like expressions, lists or tables;
11: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
12: internal value was good but RPL/2 was not able to correctly display
13: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented
14: in integer. All abs(), fabs() and labs() present in source code have ben checked
15: to avoid this kind of bug;
16: - unformatted sockets are now usable as unformatted files;
17: - BACKSPACE now runs on unformatted file;
18: - major bug is fixed in BACKSPACE that didn't check if '"' characters were

57: interrupt a loop from a subroutine within a compiled programm;
58: - workaround to avoid strange bug on slow network is written in READ
59: intrinsic;
60: - CRITICAL/END structure is added. When program enters in a critical
61: section, all other threads of the same process sleep until program leaves
62: critical section.

143: RPL/2 integer type;
144: - WFSOCK is modified to handle unconnected sockets;
145: - REGEX is added;
146: - RESTART is added (execvp() on main RPL/2 process);

226: by a new feature in glibc.
227: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
228: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
229: "ALL" IMPLICIT when it runs in interactive mode;
230: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
231: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
232: to use SAVE to manipulate global variables;
233: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
234: subroutines;
235: - fix major memory access violation in evaluation subroutine. Only occurs
236: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
237: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
238: when X was a vector or a table.

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

288: parent process was not interrupted if it is not group master process. To fix
289: this bug, SIGINJECT signal is not sent by child process but by control thread
290: in parent process;
291: - minor bug is fixed in data injection (POKE) that does not work as expected
292: when child process is protected by NRPROC.
293: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
294: - --enable-sysv-sems is added to configure script to use SystemV semaphores
295: functions instead of POSIX functions. This function is disabled or forced on
296: systems that does not provide correct POSIX or SysV semaphores subsystem;
297: - a dirty but not quick patch is written to workaround broken siginfo
298: structures. This patch has been successfully tested. It uses a segment of
299: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
300: (Unix PID);
301: - some OpenBSD's hacks are added;
302: - broken siginfo->si_pid field is now checked by configure script;
303: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

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

328: - BACKTRACE intrinsic is added;
329: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
330: when this structure is included in IFERR/THEN/END structure and when an error is
331: caught;
332: - major bug is fixed in analyse() subroutine. When evaluation() returned error
333: in a compiled program, analyse() caught this error twice and randomly aborted
334: with a segmentation error;
335: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
336: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
337: signals;
338: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
339: matrix.
340: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

344: - openssl is upgraded to 1.0.0a;
345: - interrupt stacks are now FIFO instead of LIFO;
346: - debug memory allocation subroutines are improved to run in multithreaded
347: programs;
348: - some memory leaks are fixed in process management (SPAWN and DETACH);
349: - version verification is added to shared objects;
350: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
351: linux (false mremap() prototype);
352: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
353: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
354: - all '-' are replaced by '_' in random generator list;

358: format in FCH (file descriptor) and SCK (socket descriptor);
359: - debug routines are improved;
360: - PROCID is added;
361: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
362: and to not use swap;
363: - major bug is fixed in sql support. SQL connections were closed in all chield
364: process;
365: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
366: discovered in Solaris thread safe allocators (libmalloc and libumem) that
367: are first fit class allocators. Solaris libmtmalloc works better and is
368: a best fit class allocator but its performance is poor than ptmalloc3
369: performance;
370: - major bug is fixed in ROW+ intrinsic (new row was not added where it
371: should);
372: - minor bugs are fixed in interruptions.c (semaphores values when error is
373: caught);
374: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
375: created by SPAWN;

382: This bug only occurs when RPL/2 tries to create a shared or static variable
383: from an expression;
384: - major bug is fixed in copie_etat_processus(). A field that contains
385: information about shared variable was not copied to new processus structure;
386: - some little memory leaks are fixed in evaluation(), recherche_type() and
387: sequenceur(). They only occured when syntax error were caught;
388: - IMPLICIT causes execution error instead system error;
389: - Hurd support is improved but currently broken because Hurd does not support
390: SIG_INFO. Work in progress;
391: - OpenBSD specific support is removed from sources;
392: - support for Mac OS X and Windows/Cygwin is added.
393: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

430: sends preprocessor output to standard output. This option is used by
431: rplc (RPL/2 compiler).
432: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
433: - in formatted file, string format returned a variable length string even if
434: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
435: a variable length string and 'CHARACTER*(n)' a fixed length string;
436: - keyed access files support is added. Currently, only formatted files are
437: supported;
438: - direct access files support is added. Currenlty, these files can only be used
439: in formatted mode;
440: - virtual variables are now writte in UTF-8 and all special characters
441: in string are escaped;
442: - all formatted files are now converted into UTF-8;
443: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
444: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
445: each execution (md5 and sha1 sums) to enhance security. If one of these tools
446: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
447: on a non recoverable system error;
448: - openssl and sqlite3 libraries are added;
449: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
450: variable indicates RPL/2 root directory. If it is not set, root path
451: is given by configure script (d_exec_path);
452: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
453: - configure.in and makefile.am's are modified to add Cygwin support. Interix

485: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
486: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
487: signals sent to main process were not caught because DAEMON did not replace
488: old pid by new one;
489: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
490: evaluation when an error is reported from a subroutine in another subroutine.
491: For example, error was not caught in following program when it is executed with
492: -p option :
493: TEST << iferr TEST2 then end >>
494: TEST2 << 0 inv >>
495: - major bug is fixed in variable management. Some local variables were
496: seen as global ones;
497: - major bug is fixed in rplcore. Rplcore entered in dead lock when
498: script file contains a multibyte character;
499: - IN intrinsic is added;
500: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
501: returned false ;
502: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
503: programs;
504: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
505: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
506: strings were never closed;
507: - some bugs have been fixed in file management;

509: - major bug is fixed in -A command line option (NULL character is missing);
510: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
511: made by blocks (1024 bytes). When an incomplete multibyte sequence is
512: encountered at end of block, subroutine aborts with an execution error;
513: - major bug is fixed in OPEN (TCP/IPv4 sockets).
514: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
515: - DISP now locks stdout;
516: - rpliconv is added to replace standard iconv provided by operating system.
517: Indeed, conversion between different encodages requires transliteration
518: that is not offered by some iconv utility;
519: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
520: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
521: not be found), SYSEVAL enters in a dead lock;
522: - fprintf is replaced by some functions that allow transliterations between
523: locales;
524: - '"' can now be used in strings ("\"");
525: - iconv is called with -c in preprocessor stage. It is done to write
526: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
527: - double free is fixed in liberation() (type SQL, only occurs when locale is
528: set);
529: - LOCALIZATION, UCASE and LCASE are added;
530: - major bug is fixed in EXIT intrinsic that was able to return a false
531: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
532: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
533: used in onLoading from shared library, USE was pushed on stack as algebraic
534: expression;
535: - libiconv is upgraded to 1.13.1;
536: - gnuplot is upgraded to 4.2.6;
537: - gsl is upgraded to 1.13.
538: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
539: - pipe() is overwritten by a macro to avoid a system error. Communication
540: between process are done with pipes and these pipes are managed by a
541: specific asynchrone thread. If a script try to create more threads than
542: management thread can destroy, you can quickly achieve maximum number of
543: opened files and pipe() shall return a system error. This macro tries to create
544: pipes. If pipe() function returns an error, macro waits and retries. If
545: number of retries is greater than a hardcoded value, macro returns an error;
546: - major bug (deadlock) is fixed in process and thread management. I hope
547: this bug shall be the last one;
548: - major bug is fixed in DET intrinsic (determinant was computed without LU
549: diagonalization);
550: - SWAPCNTXT is added;
551: - minor bug is fixed in Makefile.am (licences rule).
552: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
553: - some bugfixes are added in process management;
554: - all process management is rewritten to avoid usage of defunct process
555: or thread number;
556: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
557: was called before a pending interruption5 (SIGFSTOP), signal handler uses
558: a freed semaphore and corrupts heap;
559: - CLRERR is added to erase previous errors;
560: - ERRN and ERRM return exception message and number;
561: - major bug is fixed in interruptions.c. All signal are now bufferised
562: when semaphore_liste_threads is null to avoid deadlock. This bug only
563: occured when STOP was sent to a dying thread or process (when this thread or
564: process was running retrait_thread());
565: - matrix rank is computed before matrix inversion;
566: - file locks are added to stdin and stdout. stderr is not locked because
567: all messages written by signal handlers are sent to stderr;
568: - configure.in script is modified to test gcc version and avoid a bug in
569: gcc older than 4.4;
570: - some benchmarks have been done :

639: - --enable-profile flag is added to configure script. When this flag is
640: enabled, rpl is built with -pg option;
641: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
642: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
643: process is killed;
644: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
645: know typeof() intrinsic function. This function is not standard but exists
646: under Sun Studio, gcc, and maybe some others compilers. If this function does
647: not exist on your compiler, you can change its definition by old one in

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

710: that all programs that worked with old SQL intrinsic can now work with
711: SQLQUERY. With all new programs, you can open a real connection to databases;
712: - NRPROC is added. This new intrinsic is used to catch error from child
713: process. Without NRPROC, any errors returned by child process cause
714: main process to abort;
715: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
716: starts a new process). There are no mutexes in RPL/2 because all spawned process
717: use specific context. Nevertheless, shared variables and associated mutexes
718: should be added;

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

858: - -f parameter is added when iconv is called;
859: - as old file program was bugged, a new option is added to configure script.
860: When configure is called with --disable-encoding-autodetection, make does not
861: try to detect source encoding. Please, do not use if RPL/2 can be built
862: without this option !
863: - new garbage collector (and more efficient) is written;
864: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
865: not support real time signals, RPL/2 cannot use multitasking functions;

867: - -p option is added. With this option, all scripts are compiled before
868: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
869: 40% faster;
870: - read and write operations in pipe() are rewritten to be sure that such
871: operations are atomic;
872: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1066: With STATIC, next variables created by '->' are static;
1067: - PROTECT and UNPROTECT are added to protect variables against write
1068: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1069: versions of PROTECT and UNPROTECT that only deal with global variables
1070: (see RCL/SAVE);
1071: - variable management routines have been rewritten. The new ones are
1072: uncompatible with the old ones. Before these changes, a local variable
1073: was exported to a child subroutine, but cannot be modified into this
1074: child subroutine. Now, a local variable is accessible only in its subroutine;
1075: - SAVE intrinsic is added to manipulate global variables;

1517: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1518: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1519: 'MATRIX' { 2 2 3 } GETR;
1520: - LOGSCALE intrinsic is improved and now, it can be used as
1521: { "main" "auxiliary" X Y } LOGSCALE;
1522: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1523: same than AXES:
1524: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1525: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1526: { { -10 10 } "automatic" } SCALE.
1527: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1528: because it changes only the dimension of the screen. To have a logarithmic
1529: scale, you must use LOGSCALE intrinsic:
1530: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1531: screen on second scale;
1532: - { X X } autoscale and { Y Y } logscale are now invalid;
1533: - *D is added (depth multiplication, for 3D graphics);
1534: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1535: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1536: - a major bug is fixed in GETI instrinsic when it is used with a name
1537: that contains a matrix or a vector (bad upper bounds conditions in
1538: incrementation);
1539: - DISP intrinsic now uses the 33-th flag. When it is not set
1540: (default), a final carriage return is sent to the terminal;
1541: - AXES intrinsic only takes a list that can contains the keywork
1542: "main" or "auxiliary". Before this modification, this keyword was in
1543: the first stack level;
1544: - vim syntax file is upgraded;
1545: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1546: option;
1547: - LAST is now disabled in the main loop of INT intrinsic;
1548: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

1550: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1551: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1552: in 0);
1553: - LAST is disabled in the main loop of DRAW intrinsic;
1554: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1555: evaluation of an equation, the system stack is returned corrupted to the
1556: sequencer;
1557: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1558: of a loop are not integer or real.
1559: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1590: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1591: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1592: is a quick and dirty workaround...);
1593: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1594: - rplconvert is improved.
