HEAD
Correction d'un problème de signaux sous NetBSD. Le lancement du programme
pouvait échouer sur une erreur système car le thread de gestion des signaux
RPL/2 pouvait recevoir des signaux POSIX. Ce problème était aléatoire.
Typiquement, ave NetBSD 6 dans un DomU, cela fonctionnait, avec un NetBSD 6
dans VirtualBox, cela échouait à tous les coups.
1: * Tue Dec 18 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.12 (RPL/2)
2: - RPL/CAS autoconfiguration is upgraded;
3: - sqlite, openssl, giac, gmp ave been upgraded;
4: - SQLITE support is added in SQLQUERY, SQLCONNECT and SQLDISCONNECT.
5: * Tue Dec 18 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.11 (RPL/2)
6: - shared variables are now stored in a tree;
7: - lapack is upgraded to 3.4.2;
8: - only giac/src is built in rplcas (giac/Makefile.am is modified);
9: - gnuplot is upgraded to 4.6.1;
10: - giac, units and ncurses are upgraded;
11: - interprocess capabilities are removed when RPL/2 cannot run its initialization
12: routine to keep operating system as clean as possible;
13: - sem_wait() has to catch EINTR in thread_surveillance_signaux();
14: - signal management is rewritten to avoid a strange bug on NetBSD. On NetBSD,
15: a signal handler can be called within a special thread and not in the
16: calling thread;
17: - static variables are now written in a variables tree;
18: - major bug is fixed in STO intrinsic. STO returns an error when it has
19: to create a global variable if intrinsic none (default) is set.
20: * Mon Oct 1 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.10 (RPL/2)
21: - FORALL intrinsic is added;
22: - major bug (deadlock) is fixed in CYCLE. Only occurs when CYCLE is called to
23: interrupt a loop from a subroutine within a compiled programm;
24: - workaround to avoid strange bug on slow network is written in READ
25: intrinsic;
26: - CRITICAL/END structure is added. When program enters in a critical
27: section, all other threads of the same process sleep until program leaves
28: critical section.
29: * Wed Aug 22 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.9 (RPL/2)

38: - major bug is fixed in READ intrinsic (on socket). End of file condition
39: was randomly caught on slow network;
40: - stdin can now handle espaced characters strings in SYSEVAL;
41: - --with-gcc-version is added to configure script to force gcc version as
42: gfortran 4.7 is broken and crashes with segmentation fault.
43: * Mon May 21 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.8 (RPL/2)
44: - POLL now accepts more than one descriptor and returns informations
45: about pollable descriptors;
46: - SMPHRTRYDECR now takes timeout value instead of returning when semaphore
47: cannot by decremented;
48: - signal handlers are fixed to avoid spurious and very rare deadlocks;
49: - pari is upgraded;
50: - force CFLAGS for tools/file (-O2 -g) to avoid mmap() error;
51: - giac, gmp and mpfr have been upgraded.

92: - ncurses, sqlite and openssl have been upgraded;
93: - major bug is fixed in ** (integer integer **) when first argument is equal to
94: -1;
95: - major bug is fixed in signal management. With new signal management, thread or
96: process were not signalized anymore by POSIX signals. If a thread or a process
97: was sleeping, it was not interrupted;
98: - minor bug is fixed in OPEN intrinsic. Now, when a socket is open, its default
99: adress is set to 0.0.0.0;
100: - new rule is added to main makefile (make debian) to build deb package;
101: - new benchmark (Xeon W3520 @ 2.67GHz) :

105: Number of scalar operations per second and per core : 3809121.83444626
106: schroedinger:[~/cvs/bench] >
107: - recherche_type() did not convert huge integer in real. Now,
108: 18446744072742037448 is converted into real as value cannot be stored in
109: RPL/2 integer type;
110: - WFSOCK is modified to handle unconnected sockets;
111: - REGEX is added;
112: - RESTART is added (execvp() on main RPL/2 process);
113: - copie_objet() now returns same MTX (struct_mutex) even if caller wait for
114: a real copy. Now, struct_mutex contains locks owner. On Linux or Solaris (for
115: example), it is possible to lock mutex from a thread and unlock the same mutex
116: from another thread. On NetBSD, system crashes.
117: * Mon Nov 21 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.4 (RPL/2)
118: - rplcas/@GIAC@/src/config.h is removed to avoid compilation bug. config.h

130: - lists, and integer, real and complex numbers can now be written in
131: unformatted files;
132: - rplawk makefile is fixed to avoid build process bug. Warning, with these
133: modifications, sources tree has to be writable.
134: * Wed Sep 21 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.3 (RPL/2)
135: - Linux port, MacOS X port and xBSD ports are tested and fully fonctionnal;

142: * Tue Aug 9 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.2 (RPL/2)
143: - I have fixed a lot of bugs in gpp preprocessor (and sent gpp 3.0 to official
144: gpp developer). Now, macros like
145:
146: #define foo foo bar
147:
148: is evaluated without recursion. gpp 2.24 crashed on stack overflow.
149: - LIMIT is added;
150: - Now, undefined values like 'infinity/infinity' are computed. Result is
151: undef constant;
152: - infinity constant is added.

189: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
190: - major bug is fixed in STD format (1E7 sq prints 1);
191: - major bug is fixed in READ intrinsic (socket). This bug was introduced
192: by a new feature in glibc.
193: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
194: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
195: "ALL" IMPLICIT when it runs in interactive mode;
196: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
197: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
198: to use SAVE to manipulate global variables;
199: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
200: subroutines;
201: - fix major memory access violation in evaluation subroutine. Only occurs
202: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
203: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
204: when X was a vector or a table.
205: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)
206: - Gnuplot is upgraded;
207: - flag 34 is now used to enable or disable control character evaluation;
208: - major bug is fixed in P->R intrinsic function when argument type is
209: complex and degree mode is set;
210: - L->T and T->L are added;
211: - OLD filetype is fixed;
212: - FLOW socket support is added;
213: - FLOW sequential files are added;
214: - new escape sequence is added to handle flow files (\x + hexadecimal code).
215: Known escape sequences are \", \b, \n, \t, \x?? and \\.
216: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
217: - Ncurses is upgraded to 5.8;
218: - ALARM is fixed by filling isdst field;
219: - catch ECONNRESET in write intrinsic to return an execution error instead of
220: system one;
221: - fix a typo in HELP intrinsic;
222: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;
223: - Lapack is upgraded to 3.3.0;
224: - libmtmalloc is now default Solaris allocator;
225: - ncurses is upgraded;
226: - regression introduced by 4.0.19 is fixed in signal management.
227: Interruption1() could be called from itself and raises bus error (on sparc) or
228: segmentation fault;
229: - sqlite is upgraded to 3.7.4;
230: - OpenSSL is upgraded to 1.0.0c;
231: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);
232: - characters are tested in recherche_type() to avoid names like '12+';
233: - gnuplot is upgraded to 4.4.2 due to major bugs.
234: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
235: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
236: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
237: corruption. As internal memory management have been improved, a best fit
238: allocator like ptmalloc3 is not required anymore;
239: - gnuplot is upgraded to 4.4.1;
240: - deadlock is fixed in signal handlers: same mutex was used in standard
241: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
242: and signal handlers. A new signal handler specific mutex is added;
243: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
244: that has to be evaluated by ->NUM;
245: - rplfile build process is modify to be sure that rplfile is not modified
246: after rpl build stage (to be sure that rplfile checksum is not modified after
247: rpl compilation);
248: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
249: modified to remove yacc code and renamed;
250: - some workarounds have been written to not use buggy klibc SystemV IPCS.
251: ABORT now works on eComStation;
252: - sqlite is upgraded to 3.7.2;
253: - bug is fixed in software interrupts. When both process have different PID,
254: parent process was not interrupted if it is not group master process. To fix
255: this bug, SIGINJECT signal is not sent by child process but by control thread
256: in parent process;
257: - minor bug is fixed in data injection (POKE) that does not work as expected
258: when child process is protected by NRPROC.
259: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
260: - --enable-sysv-sems is added to configure script to use SystemV semaphores
261: functions instead of POSIX functions. This function is disabled or forced on
262: systems that does not provide correct POSIX or SysV semaphores subsystem;
263: - a dirty but not quick patch is written to workaround broken siginfo
264: structures. This patch has been successfully tested. It uses a segment of
265: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
266: (Unix PID);
267: - some OpenBSD's hacks are added;
268: - broken siginfo->si_pid field is now checked by configure script;
269: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
270: - random generator is cloned by SPAWN;
271: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
272: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
273: or freeaddrinfo;
274: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
275: - major bug is fixed in CHR intrinsic when obtained character is not printable;
276: - Lapack is upgraded to 3.2.2;
277: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
278: - TOKENIZE is now able to convert escape sequences;
279: - ATPOKE and CLRATPOKE new intrinsics are added;
280: - --enable-full-static configure flag is added. With this flag, mysql and
281: postgresql libraries are statically linked in rpl executable;
282: - units Makefile is modified to avoid readline and ncurses usages;
283: - sqlite is upgraded to 3.7.0.1;
284: - units is upgraded to 1.88;
285: - another major bug is fixed in the same variable creation subroutine.
286: Level 0 and 1 variables adresses were swapped when a global variable masked
287: a name of RPL/2 routine;
288: - major bug is fixed in global variable creation subroutine. When a global
289: variable was created and when a local variable existed with the same name,
290: computed address of global variable was wrong;
291: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
292: is forced in front of all libraries.
293: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
294: - BACKTRACE intrinsic is added;
295: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
296: when this structure is included in IFERR/THEN/END structure and when an error is
297: caught;
298: - major bug is fixed in analyse() subroutine. When evaluation() returned error
299: in a compiled program, analyse() caught this error twice and randomly aborted
300: with a segmentation error;
301: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
302: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
303: signals;
304: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
305: matrix.
306: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
307: - minor bug is fixed in evaluation() subroutine. With this patch, same program
308: returns same result with or without -p flag;
309: - ncurses 5.7 is upgraded to 20100619;
310: - openssl is upgraded to 1.0.0a;
311: - interrupt stacks are now FIFO instead of LIFO;
312: - debug memory allocation subroutines are improved to run in multithreaded
313: programs;
314: - some memory leaks are fixed in process management (SPAWN and DETACH);
315: - version verification is added to shared objects;
316: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
317: linux (false mremap() prototype);
318: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
319: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
320: - all '-' are replaced by '_' in random generator list;
321: - minor memory leak is fixed in OPEN intrinsic (socket);
322: - major bug is fixed in IFERR structure. Only occurs in compiled program;
323: - major bug is fixed in copie_objet() and liberation(). Only concerns
324: format in FCH (file descriptor) and SCK (socket descriptor);
325: - debug routines are improved;
326: - PROCID is added;
327: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
328: and to not use swap;
329: - major bug is fixed in sql support. SQL connections were closed in all chield
330: process;
331: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
332: discovered in Solaris thread safe allocators (libmalloc and libumem) that
333: are first fit class allocators. Solaris libmtmalloc works better and is
334: a best fit class allocator but its performance is poor than ptmalloc3
335: performance;
336: - major bug is fixed in ROW+ intrinsic (new row was not added where it
337: should);
338: - minor bugs are fixed in interruptions.c (semaphores values when error is
339: caught);
340: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
341: created by SPAWN;
342: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
343: ATEXIT. If it receives SIGFABORT, it does not;
344: - ONEXIT is renamed in ATEXIT;
345: - ONEXIT new intrinsic is added.
346: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
347: - major bug is fixed in static and shared variables initialization subroutine.
348: This bug only occurs when RPL/2 tries to create a shared or static variable
349: from an expression;
350: - major bug is fixed in copie_etat_processus(). A field that contains
351: information about shared variable was not copied to new processus structure;
352: - some little memory leaks are fixed in evaluation(), recherche_type() and
353: sequenceur(). They only occured when syntax error were caught;
354: - IMPLICIT causes execution error instead system error;
355: - Hurd support is improved but currently broken because Hurd does not support
356: SIG_INFO. Work in progress;
357: - OpenBSD specific support is removed from sources;
358: - support for Mac OS X and Windows/Cygwin is added.
359: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)
360: - implicit names can now be disabled by new IMPLICIT intrinsic:

386: RPL/2 aborts because the last Z is undefined and not protected by ''.
387: By default, implicit is set to "ALL";
388: - sqlite is upgraded to 3.6.23.1;
389: - openssl is upgraded to 1.0.0;
390: - major bug is fixed in RETURN intrinsic. It only occurs in evaluation
391: subroutine;
392: - table variable can now be sorted by SORT;
393: - some regressions between libtool 1.x and 2.x are fixed by workarouds in
394: Makefiles;
395: - -a command line option analyzes program (structure and syntax) and
396: sends preprocessor output to standard output. This option is used by
397: rplc (RPL/2 compiler).
398: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
399: - in formatted file, string format returned a variable length string even if
400: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
401: a variable length string and 'CHARACTER*(n)' a fixed length string;
402: - keyed access files support is added. Currently, only formatted files are
403: supported;
404: - direct access files support is added. Currenlty, these files can only be used
405: in formatted mode;
406: - virtual variables are now writte in UTF-8 and all special characters
407: in string are escaped;
408: - all formatted files are now converted into UTF-8;
409: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
410: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
411: each execution (md5 and sha1 sums) to enhance security. If one of these tools
412: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
413: on a non recoverable system error;
414: - openssl and sqlite3 libraries are added;
415: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
416: variable indicates RPL/2 root directory. If it is not set, root path
417: is given by configure script (d_exec_path);
418: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
419: - configure.in and makefile.am's are modified to add Cygwin support. Interix

422: - TeX files are now written in UTF-8 even default locale differs;
423: - minor bug is fixed in ->STR (escaped characters);
424: - minor bug is fixed in ->Q intrinsic. Resultat is returned as integer
425: fraction intead real one;
426: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
427: - Makefile.am are modified to authorize parallel builds;
428: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
429: and writes warning to standard output;
430: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)
431: - escape codes are now converted in formateur(), not in recherche_type() to
432: avoid a minor bug in EDIT and VISIT intrinsics;

434: - file-5.03 is patched to avoid bus error on systems that require memory
435: alignment;
436: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
437: were able to be avoided by evaluation routine.

447: - sockets options are now set before bind();
448: - shutdown() is added to all connected sockets;
449: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
450: list argument and inexistant elements).
451: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
452: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
453: signals sent to main process were not caught because DAEMON did not replace
454: old pid by new one;
455: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
456: evaluation when an error is reported from a subroutine in another subroutine.
457: For example, error was not caught in following program when it is executed with
458: -p option :
459: TEST << iferr TEST2 then end >>
460: TEST2 << 0 inv >>
461: - major bug is fixed in variable management. Some local variables were
462: seen as global ones;
463: - major bug is fixed in rplcore. Rplcore entered in dead lock when
464: script file contains a multibyte character;
465: - IN intrinsic is added;
466: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
467: returned false ;
468: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
469: programs;
470: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
471: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
472: strings were never closed;
473: - some bugs have been fixed in file management;

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

608: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
609: process is killed;
610: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
611: know typeof() intrinsic function. This function is not standard but exists
612: under Sun Studio, gcc, and maybe some others compilers. If this function does
613: not exist on your compiler, you can change its definition by old one in
614: src/rpl.h;

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

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

771: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
772: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
773: workaround for this major bug. Nevertheless, all others capabilities seems to
774: work fine;
775: - '->' is modified to return error when program tries to initialiaze two
776: variables with the same name like
777: 1 0 -> I I << ... >>;

797: - VERIFY intrinsic is written;
798: - PSHCNTXT and PULCNTXT are added (PSHCNTXT pushes context on an
799: internal contexts stack, PULCNTXT pulls contexts from this internal stack).
800: Main usages of these intrinsics are in conjonction with IFERR or with
801: software interrupts;
802: - HEAD, TAIL and REVLIST intrinsics are added;

823: before starting interrupt evaluation;
824: - -f parameter is added when iconv is called;
825: - as old file program was bugged, a new option is added to configure script.
826: When configure is called with --disable-encoding-autodetection, make does not
827: try to detect source encoding. Please, do not use if RPL/2 can be built
828: without this option !
829: - new garbage collector (and more efficient) is written;
830: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
831: not support real time signals, RPL/2 cannot use multitasking functions;
832: - error returned by preprocessor are now catched by RPL/2;
833: - -p option is added. With this option, all scripts are compiled before
834: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
835: 40% faster;
836: - read and write operations in pipe() are rewritten to be sure that such
837: operations are atomic;
838: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be
839: linear;

1033: - PROTECT and UNPROTECT are added to protect variables against write
1034: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1035: versions of PROTECT and UNPROTECT that only deal with global variables
1036: (see RCL/SAVE);
1037: - variable management routines have been rewritten. The new ones are
1038: uncompatible with the old ones. Before these changes, a local variable
1039: was exported to a child subroutine, but cannot be modified into this
1040: child subroutine. Now, a local variable is accessible only in its subroutine;
1041: - SAVE intrinsic is added to manipulate global variables;

1363: - NOT is not correctly formatted in formateur.c:
1364: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1365: with a NOTZ function !
1366: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

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

1480: VISIT does not find a name in level 1;
1481: - configure.in script is modified to add a new test (--enable-debug
1482: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1483: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1484: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1485: 'MATRIX' { 2 2 3 } GETR;
1486: - LOGSCALE intrinsic is improved and now, it can be used as
1487: { "main" "auxiliary" X Y } LOGSCALE;
1488: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1489: same than AXES:
1490: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1491: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1492: { { -10 10 } "automatic" } SCALE.
1493: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1494: because it changes only the dimension of the screen. To have a logarithmic
1495: scale, you must use LOGSCALE intrinsic:
1496: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1497: screen on second scale;
1498: - { X X } autoscale and { Y Y } logscale are now invalid;
1499: - *D is added (depth multiplication, for 3D graphics);
1500: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1501: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
