En route pour la 4.1.5. Correction d'un bug mineur sur les mutexes.
Préparation d'un mécanisme pour éviter qu'un mutex soit déverrouillé
depuis un thread qui ne l'a pas verrouillé.
1: * Mon Nov 21 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.5 (RPL/2)
2: - copie_objet() now returns same MTX (struct_mutex) even if caller wait for
3: a real copy. Now, struct_mutex contains locks owner. On Linux or Solaris (for
4: example), it is possible to lock mutex from a thread and unlock the same mutex
5: from another thread. On NetBSD, system crashes.
6: * Mon Nov 21 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.4 (RPL/2)
7: - rplcas/@GIAC@/src/config.h is removed to avoid compilation bug. config.h
8: written by configure script was overloaded by src/config.h;
9: - lot of compilation warnings have been fixed;
10: - lapack and blas have been upgraded;
11: - ncurses, sqlite and giac have been upgraded;
12: - LCASE, UCASE, POS and SUB now handle escape characters;
13: - major bug is fixed in INT (numerical integration was unusable as type
14: checking condition was always false);
15: - SIZE, CHR and NUM can handle strings with escape characters;
16: - lot of patches for Android and OS/2;
17: - configure.ac is improved to remove operating systems special cases.
18: - major bug is fixed in DRWS (SDAT was not used...);
19: - lists, and integer, real and complex numbers can now be written in
20: unformatted files;
21: - rplawk makefile is fixed to avoid build process bug. Warning, with these
22: modifications, sources tree has to be writable.
23: * Wed Sep 21 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.3 (RPL/2)

33: gpp developer). Now, macros like
34:
35: #define foo foo bar
36:
37: is evaluated without recursion. gpp 2.24 crashed on stack overflow.
38: - LIMIT is added;
39: - Now, undefined values like 'infinity/infinity' are computed. Result is
40: undef constant;

73: Number of scalar operations per second and per core : 2625369.22710792
74: * Mon Jun 20 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.0.prerelease.0 (RPL/2)
75: - New variable management is written. Please note that -p flag does not work
76: and all multithread/multitask capabilities have been disabled until this
77: new subsystem shall be validated.
78: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
79: - major bug is fixed in STD format (1E7 sq prints 1);
80: - major bug is fixed in READ intrinsic (socket). This bug was introduced
81: by a new feature in glibc.
82: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
83: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
84: "ALL" IMPLICIT when it runs in interactive mode;
85: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
86: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
87: to use SAVE to manipulate global variables;
88: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
89: subroutines;
90: - fix major memory access violation in evaluation subroutine. Only occurs
91: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
92: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
93: when X was a vector or a table.
94: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)
95: - Gnuplot is upgraded;
96: - flag 34 is now used to enable or disable control character evaluation;
97: - major bug is fixed in P->R intrinsic function when argument type is
98: complex and degree mode is set;
99: - L->T and T->L are added;
100: - OLD filetype is fixed;
101: - FLOW socket support is added;
102: - FLOW sequential files are added;
103: - new escape sequence is added to handle flow files (\x + hexadecimal code).
104: Known escape sequences are \", \b, \n, \t, \x?? and \\.
105: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
106: - Ncurses is upgraded to 5.8;
107: - ALARM is fixed by filling isdst field;
108: - catch ECONNRESET in write intrinsic to return an execution error instead of
109: system one;
110: - fix a typo in HELP intrinsic;
111: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;
112: - Lapack is upgraded to 3.3.0;
113: - libmtmalloc is now default Solaris allocator;
114: - ncurses is upgraded;
115: - regression introduced by 4.0.19 is fixed in signal management.
116: Interruption1() could be called from itself and raises bus error (on sparc) or
117: segmentation fault;
118: - sqlite is upgraded to 3.7.4;
119: - OpenSSL is upgraded to 1.0.0c;
120: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);
121: - characters are tested in recherche_type() to avoid names like '12+';
122: - gnuplot is upgraded to 4.4.2 due to major bugs.
123: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
124: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
125: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
126: corruption. As internal memory management have been improved, a best fit
127: allocator like ptmalloc3 is not required anymore;
128: - gnuplot is upgraded to 4.4.1;
129: - deadlock is fixed in signal handlers: same mutex was used in standard
130: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
131: and signal handlers. A new signal handler specific mutex is added;
132: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
133: that has to be evaluated by ->NUM;
134: - rplfile build process is modify to be sure that rplfile is not modified
135: after rpl build stage (to be sure that rplfile checksum is not modified after
136: rpl compilation);
137: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
138: modified to remove yacc code and renamed;
139: - some workarounds have been written to not use buggy klibc SystemV IPCS.
140: ABORT now works on eComStation;
141: - sqlite is upgraded to 3.7.2;
142: - bug is fixed in software interrupts. When both process have different PID,
143: parent process was not interrupted if it is not group master process. To fix
144: this bug, SIGINJECT signal is not sent by child process but by control thread
145: in parent process;
146: - minor bug is fixed in data injection (POKE) that does not work as expected
147: when child process is protected by NRPROC.
148: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
149: - --enable-sysv-sems is added to configure script to use SystemV semaphores
150: functions instead of POSIX functions. This function is disabled or forced on
151: systems that does not provide correct POSIX or SysV semaphores subsystem;
152: - a dirty but not quick patch is written to workaround broken siginfo
153: structures. This patch has been successfully tested. It uses a segment of
154: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
155: (Unix PID);
156: - some OpenBSD's hacks are added;
157: - broken siginfo->si_pid field is now checked by configure script;
158: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
159: - random generator is cloned by SPAWN;
160: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
161: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
162: or freeaddrinfo;
163: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
164: - major bug is fixed in CHR intrinsic when obtained character is not printable;
165: - Lapack is upgraded to 3.2.2;
166: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
167: - TOKENIZE is now able to convert escape sequences;
168: - ATPOKE and CLRATPOKE new intrinsics are added;
169: - --enable-full-static configure flag is added. With this flag, mysql and
170: postgresql libraries are statically linked in rpl executable;
171: - units Makefile is modified to avoid readline and ncurses usages;
172: - sqlite is upgraded to 3.7.0.1;
173: - units is upgraded to 1.88;
174: - another major bug is fixed in the same variable creation subroutine.
175: Level 0 and 1 variables adresses were swapped when a global variable masked
176: a name of RPL/2 routine;
177: - major bug is fixed in global variable creation subroutine. When a global
178: variable was created and when a local variable existed with the same name,
179: computed address of global variable was wrong;
180: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
181: is forced in front of all libraries.
182: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
183: - BACKTRACE intrinsic is added;
184: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
185: when this structure is included in IFERR/THEN/END structure and when an error is
186: caught;
187: - major bug is fixed in analyse() subroutine. When evaluation() returned error
188: in a compiled program, analyse() caught this error twice and randomly aborted
189: with a segmentation error;
190: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
191: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
192: signals;
193: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
194: matrix.
195: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
196: - minor bug is fixed in evaluation() subroutine. With this patch, same program
197: returns same result with or without -p flag;
198: - ncurses 5.7 is upgraded to 20100619;
199: - openssl is upgraded to 1.0.0a;
200: - interrupt stacks are now FIFO instead of LIFO;
201: - debug memory allocation subroutines are improved to run in multithreaded
202: programs;
203: - some memory leaks are fixed in process management (SPAWN and DETACH);
204: - version verification is added to shared objects;
205: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
206: linux (false mremap() prototype);
207: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
208: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
209: - all '-' are replaced by '_' in random generator list;
210: - minor memory leak is fixed in OPEN intrinsic (socket);
211: - major bug is fixed in IFERR structure. Only occurs in compiled program;
212: - major bug is fixed in copie_objet() and liberation(). Only concerns
213: format in FCH (file descriptor) and SCK (socket descriptor);
214: - debug routines are improved;
215: - PROCID is added;
216: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
217: and to not use swap;
218: - major bug is fixed in sql support. SQL connections were closed in all chield
219: process;
220: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
221: discovered in Solaris thread safe allocators (libmalloc and libumem) that
222: are first fit class allocators. Solaris libmtmalloc works better and is
223: a best fit class allocator but its performance is poor than ptmalloc3
224: performance;
225: - major bug is fixed in ROW+ intrinsic (new row was not added where it
226: should);
227: - minor bugs are fixed in interruptions.c (semaphores values when error is
228: caught);
229: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
230: created by SPAWN;
231: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
232: ATEXIT. If it receives SIGFABORT, it does not;
233: - ONEXIT is renamed in ATEXIT;
234: - ONEXIT new intrinsic is added.
235: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
236: - major bug is fixed in static and shared variables initialization subroutine.
237: This bug only occurs when RPL/2 tries to create a shared or static variable
238: from an expression;
239: - major bug is fixed in copie_etat_processus(). A field that contains
240: information about shared variable was not copied to new processus structure;
241: - some little memory leaks are fixed in evaluation(), recherche_type() and
242: sequenceur(). They only occured when syntax error were caught;
243: - IMPLICIT causes execution error instead system error;
244: - Hurd support is improved but currently broken because Hurd does not support
245: SIG_INFO. Work in progress;
246: - OpenBSD specific support is removed from sources;
247: - support for Mac OS X and Windows/Cygwin is added.
248: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)
249: - implicit names can now be disabled by new IMPLICIT intrinsic:

287: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
288: - in formatted file, string format returned a variable length string even if
289: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
290: a variable length string and 'CHARACTER*(n)' a fixed length string;
291: - keyed access files support is added. Currently, only formatted files are
292: supported;
293: - direct access files support is added. Currenlty, these files can only be used
294: in formatted mode;
295: - virtual variables are now writte in UTF-8 and all special characters
296: in string are escaped;
297: - all formatted files are now converted into UTF-8;
298: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
299: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
300: each execution (md5 and sha1 sums) to enhance security. If one of these tools
301: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
302: on a non recoverable system error;
303: - openssl and sqlite3 libraries are added;
304: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
305: variable indicates RPL/2 root directory. If it is not set, root path
306: is given by configure script (d_exec_path);
307: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
308: - configure.in and makefile.am's are modified to add Cygwin support. Interix

314: fraction intead real one;
315: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
316: - Makefile.am are modified to authorize parallel builds;
317: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
318: and writes warning to standard output;
319: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)

340: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
341: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
342: signals sent to main process were not caught because DAEMON did not replace
343: old pid by new one;
344: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
345: evaluation when an error is reported from a subroutine in another subroutine.
346: For example, error was not caught in following program when it is executed with
347: -p option :
348: TEST << iferr TEST2 then end >>
349: TEST2 << 0 inv >>
350: - major bug is fixed in variable management. Some local variables were
351: seen as global ones;
352: - major bug is fixed in rplcore. Rplcore entered in dead lock when
353: script file contains a multibyte character;
354: - IN intrinsic is added;
355: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
356: returned false ;
357: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
358: programs;
359: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
360: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
361: strings were never closed;
362: - some bugs have been fixed in file management;

364: - major bug is fixed in -A command line option (NULL character is missing);
365: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
366: made by blocks (1024 bytes). When an incomplete multibyte sequence is
367: encountered at end of block, subroutine aborts with an execution error;
368: - major bug is fixed in OPEN (TCP/IPv4 sockets).
369: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
370: - DISP now locks stdout;
371: - rpliconv is added to replace standard iconv provided by operating system.
372: Indeed, conversion between different encodages requires transliteration
373: that is not offered by some iconv utility;
374: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
375: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
376: not be found), SYSEVAL enters in a dead lock;
377: - fprintf is replaced by some functions that allow transliterations between
378: locales;
379: - '"' can now be used in strings ("\"");
380: - iconv is called with -c in preprocessor stage. It is done to write
381: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
382: - double free is fixed in liberation() (type SQL, only occurs when locale is
383: set);
384: - LOCALIZATION, UCASE and LCASE are added;
385: - major bug is fixed in EXIT intrinsic that was able to return a false
386: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
387: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
388: used in onLoading from shared library, USE was pushed on stack as algebraic
389: expression;
390: - libiconv is upgraded to 1.13.1;
391: - gnuplot is upgraded to 4.2.6;
392: - gsl is upgraded to 1.13.
393: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
394: - pipe() is overwritten by a macro to avoid a system error. Communication
395: between process are done with pipes and these pipes are managed by a
396: specific asynchrone thread. If a script try to create more threads than
397: management thread can destroy, you can quickly achieve maximum number of
398: opened files and pipe() shall return a system error. This macro tries to create
399: pipes. If pipe() function returns an error, macro waits and retries. If
400: number of retries is greater than a hardcoded value, macro returns an error;
401: - major bug (deadlock) is fixed in process and thread management. I hope
402: this bug shall be the last one;
403: - major bug is fixed in DET intrinsic (determinant was computed without LU
404: diagonalization);
405: - SWAPCNTXT is added;
406: - minor bug is fixed in Makefile.am (licences rule).
407: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
408: - some bugfixes are added in process management;
409: - all process management is rewritten to avoid usage of defunct process
410: or thread number;
411: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
412: was called before a pending interruption5 (SIGFSTOP), signal handler uses
413: a freed semaphore and corrupts heap;
414: - CLRERR is added to erase previous errors;
415: - ERRN and ERRM return exception message and number;
416: - major bug is fixed in interruptions.c. All signal are now bufferised
417: when semaphore_liste_threads is null to avoid deadlock. This bug only
418: occured when STOP was sent to a dying thread or process (when this thread or
419: process was running retrait_thread());
420: - matrix rank is computed before matrix inversion;
421: - file locks are added to stdin and stdout. stderr is not locked because
422: all messages written by signal handlers are sent to stderr;
423: - configure.in script is modified to test gcc version and avoid a bug in
424: gcc older than 4.4;
425: - some benchmarks have been done :

497: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
498: process is killed;
499: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
500: know typeof() intrinsic function. This function is not standard but exists
501: under Sun Studio, gcc, and maybe some others compilers. If this function does
502: not exist on your compiler, you can change its definition by old one in
503: src/rpl.h;
504: - fflush() can now be interrupted by signal (SunOS);
505: - fflush(NULL) is called before all fork() occurrences;

526: deadlock when a huge amount of threads is launched);
527: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
528: arguments types are unsupported;
529: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
530: data are buffered. PLOT is used to draw these objects.);
531: - MARK instrinsic is added;

544: static variable that is shared by multiple threads;
545: - '->' intrinsic is improved. All object copies have been avoided;
546: - -n flag is added to catch HUP signal. stderr and stdout are redirected
547: to a file, stdin is redirected to /dev/null when control process is killed;
548: - a mutex is added to each object (before this modification,
549: RPL/2 used a global mutex and performances in multithreaded programs were very
550: poor.);

564: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
565: that all programs that worked with old SQL intrinsic can now work with
566: SQLQUERY. With all new programs, you can open a real connection to databases;
567: - NRPROC is added. This new intrinsic is used to catch error from child
568: process. Without NRPROC, any errors returned by child process cause
569: main process to abort;
570: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
571: starts a new process). There are no mutexes in RPL/2 because all spawned process
572: use specific context. Nevertheless, shared variables and associated mutexes
573: should be added;
574: - -D flag and DAEMONIZE intrinsic have been added;

660: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
661: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
662: workaround for this major bug. Nevertheless, all others capabilities seems to
663: work fine;
664: - '->' is modified to return error when program tries to initialiaze two

712: before starting interrupt evaluation;
713: - -f parameter is added when iconv is called;
714: - as old file program was bugged, a new option is added to configure script.
715: When configure is called with --disable-encoding-autodetection, make does not
716: try to detect source encoding. Please, do not use if RPL/2 can be built
717: without this option !
718: - new garbage collector (and more efficient) is written;
719: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
720: not support real time signals, RPL/2 cannot use multitasking functions;
721: - error returned by preprocessor are now catched by RPL/2;
722: - -p option is added. With this option, all scripts are compiled before
723: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
724: 40% faster;
725: - read and write operations in pipe() are rewritten to be sure that such
726: operations are atomic;

754: greater than one second. On some systems, usleep argument must be lower
755: than 1E6;
756: - numeric and character formats are now tested;
757: - -A flag is added. -A is used to give command line parameters to main

868: - external wrapper (rplplot) is written to force usage of gnuplot provided
869: by RPL/2 if it is built during build process. If this build does not exist,
870: it tries to launch regular gnuplot;
871: - gnuplot is added to source tree to avoid some trouble between preinstalled
872: gnuplot and release used by RPL/2. This addition to source tree is
873: required by some incompatibility between gnuplot releases;
874: - Lapack is upgraded to 3.1.1 release;
875: - GSL is upgraded to 1.9 revision;

921: With STATIC, next variables created by '->' are static;
922: - PROTECT and UNPROTECT are added to protect variables against write
923: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
924: versions of PROTECT and UNPROTECT that only deal with global variables
925: (see RCL/SAVE);
926: - variable management routines have been rewritten. The new ones are
927: uncompatible with the old ones. Before these changes, a local variable
928: was exported to a child subroutine, but cannot be modified into this
929: child subroutine. Now, a local variable is accessible only in its subroutine;
930: - SAVE intrinsic is added to manipulate global variables;

1251: fine...);
1252: - NOT is not correctly formatted in formateur.c:
1253: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1254: with a NOTZ function !
1255: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1258: - RPL/2 is tested with efence and valgrind;
1259: - configure.in script is modified;
1260: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1321: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1322: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1323: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1340: - SCLS is added;
1341: - DRWS now uses COLS to draw 2D graphics;
1342: - PPAR and SPAR are written. SPAR returns a list that contains the
1343: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1344: statistical variable, or "DISABLED" if its type is not one of the type of
1345: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1346: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1347: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1348: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1349: disabled. Arguments of EXTERNAL are case sensitive because the external
1350: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1351: of known external functions but add the new list to the last. { "all" }
1352: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1353: external names of the known functions;
1354: - mkrplso.in is modified.
1355: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1356: - vim syntax file is upgraded;
1357: - a minor mistake is fixed in recherche_instruction_suivante();
1358: - some minor memory leaks are fixed in recherche_type() function. They only

1367: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1368: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1369: VISIT does not find a name in level 1;
1370: - configure.in script is modified to add a new test (--enable-debug
1371: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1372: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1373: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1374: 'MATRIX' { 2 2 3 } GETR;
1375: - LOGSCALE intrinsic is improved and now, it can be used as
1376: { "main" "auxiliary" X Y } LOGSCALE;
1377: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1378: same than AXES:
1379: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1380: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1381: { { -10 10 } "automatic" } SCALE.
1382: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1383: because it changes only the dimension of the screen. To have a logarithmic
1384: scale, you must use LOGSCALE intrinsic:
1385: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1386: screen on second scale;
1387: - { X X } autoscale and { Y Y } logscale are now invalid;
1388: - *D is added (depth multiplication, for 3D graphics);
1389: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1390: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1391: - a major bug is fixed in GETI instrinsic when it is used with a name
1392: that contains a matrix or a vector (bad upper bounds conditions in
1393: incrementation);
1394: - DISP intrinsic now uses the 33-th flag. When it is not set
1395: (default), a final carriage return is sent to the terminal;
1396: - AXES intrinsic only takes a list that can contains the keywork
1397: "main" or "auxiliary". Before this modification, this keyword was in
1398: the first stack level;
1399: - vim syntax file is upgraded;
1400: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1401: option;
1402: - LAST is now disabled in the main loop of INT intrinsic;
1403: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1404: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1405: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1406: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1407: in 0);
1408: - LAST is disabled in the main loop of DRAW intrinsic;
1409: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1410: evaluation of an equation, the system stack is returned corrupted to the
1411: sequencer;
1412: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1413: of a loop are not integer or real.
1414: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1415: - the compilation stage aborts with an error message when two definitions
1416: have the same name. To improve the compilation() subroutine, I have to
1417: add some tests in gestion_variables.c;
1418: - recherche_type() subroutine ad some other connex subroutines are improved.
1419: Now, some syntax errors about object are caught and do not perform sequencer
1420: hangup;
1421: - readline is upgraded (minor compilation bug with recent gcc);
1422: - Makefile.am's and configure.in scripts are improved.
1423: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1424: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1425: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1426: the boxwidth, 1 by default);
1427: - recherche_type() is rewritten to be faster;
1428: - gsl is upgraded (release 1.3);
1429: - ncurses is upgraded and patched (release 5.3);
1430: - recherche_instruction_suivante() is fixed (string research with included
1431: '"') and rewritten to be faster;
1432: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1433: segfault.
1434: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1442: - a minor bug is fixed in evaluation subroutine;
1443: - vim syntax file is improved;
1444: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1445: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1446: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1447: is a quick and dirty workaround...);
1448: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1449: - rplconvert is improved.

1507: 'X' 0 + and 0 'X' + return 'X';
1508: 'X' 0 - returns 'X';
1509: 'X' 1 * and 1 'X' * return 'X';

1515: found by configure are used in rpltypes.h (rplconfig.h is written by configure);
1516: - rdynamic flag is added in src/Makefile.am. This flag is used in the first
1517: makefile, but forgotten in the new process;
1518: - Flag 31 is tested before saving any arguments in bibliotheques_externes.c;
1519: - POS can now be used on lists;

1531: deleted too!;
1532: - configure script is improved (and it seems to be good ;-) );
1533: - An --disable-experimental flag is added to the configure script. Thus, even
1534: if you compile a beta release, you can compile a stable RPL/2;
1535: - new syntax and ftplugin written for vim 6.0.

1548: that the RPL/2 seqencer must stop and must give a prompt. This
1549: signal is an asynchonous "HALT" command;
1550: - SIGINT (CTRL+C) variables stack corruption is fixed;
1551: - IFERR seems to be fixed (in equation evaluation routine);
1552: - Memory leak is fixed (ADR object type);

1559: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1560: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1561: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1562:
1563: Newton:[~/rpl/rpl] > time make install
1564: ...
1565: real 338m39.623s
1566: user 324m32.290s
1567: sys 10m47.380s
1568: Newton:[~/rpl/rpl] >
1569:
1570: I don't know if you will compile this language on old worstations, but
1571: it is usable ;-) ;
1572: - SYSEVAL is improved. An external program can be called without any shell.
