16: schroedinger:[~/cvs/bench] >
1.99 bertrand 17: - recherche_type() did not convert huge integer in real. Now,
18: 18446744072742037448 is converted into real as value cannot be stored in
19: RPL/2 integer type;
20: - WFSOCK is modified to handle unconnected sockets;
1.98 bertrand 21: - REGEX is added;

24: a real copy. Now, struct_mutex contains locks owner. On Linux or Solaris (for
25: example), it is possible to lock mutex from a thread and unlock the same mutex
26: from another thread. On NetBSD, system crashes.

99: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
100: - major bug is fixed in STD format (1E7 sq prints 1);
101: - major bug is fixed in READ intrinsic (socket). This bug was introduced
102: by a new feature in glibc.
103: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
104: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
105: "ALL" IMPLICIT when it runs in interactive mode;
106: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
107: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
108: to use SAVE to manipulate global variables;
109: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
110: subroutines;
111: - fix major memory access violation in evaluation subroutine. Only occurs
112: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
113: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
114: when X was a vector or a table.
1.63 bertrand 115: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

125: Known escape sequences are \", \b, \n, \t, \x?? and \\.
1.60 bertrand 126: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
127: - Ncurses is upgraded to 5.8;
128: - ALARM is fixed by filling isdst field;
129: - catch ECONNRESET in write intrinsic to return an execution error instead of
130: system one;
131: - fix a typo in HELP intrinsic;
132: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;
1.57 bertrand 133: - Lapack is upgraded to 3.3.0;
1.58 bertrand 134: - libmtmalloc is now default Solaris allocator;
1.56 bertrand 135: - ncurses is upgraded;
1.60 bertrand 136: - regression introduced by 4.0.19 is fixed in signal management.
1.59 bertrand 137: Interruption1() could be called from itself and raises bus error (on sparc) or
1.55 bertrand 138: segmentation fault;
139: - sqlite is upgraded to 3.7.4;
1.54 bertrand 140: - OpenSSL is upgraded to 1.0.0c;

1.53 bertrand 143: - gnuplot is upgraded to 4.4.2 due to major bugs.
1.52 bertrand 144: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
145: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
146: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
147: corruption. As internal memory management have been improved, a best fit
148: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 149: - gnuplot is upgraded to 4.4.1;
150: - deadlock is fixed in signal handlers: same mutex was used in standard
151: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
152: and signal handlers. A new signal handler specific mutex is added;
153: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
154: that has to be evaluated by ->NUM;
1.49 bertrand 155: - rplfile build process is modify to be sure that rplfile is not modified
156: after rpl build stage (to be sure that rplfile checksum is not modified after
157: rpl compilation);
1.51 bertrand 158: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
159: modified to remove yacc code and renamed;
1.47 bertrand 160: - some workarounds have been written to not use buggy klibc SystemV IPCS.
161: ABORT now works on eComStation;
162: - sqlite is upgraded to 3.7.2;
163: - bug is fixed in software interrupts. When both process have different PID,
164: parent process was not interrupted if it is not group master process. To fix
165: this bug, SIGINJECT signal is not sent by child process but by control thread
166: in parent process;
1.46 bertrand 167: - minor bug is fixed in data injection (POKE) that does not work as expected
168: when child process is protected by NRPROC.
1.44 bertrand 169: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 170: - --enable-sysv-sems is added to configure script to use SystemV semaphores
171: functions instead of POSIX functions. This function is disabled or forced on
172: systems that does not provide correct POSIX or SysV semaphores subsystem;
173: - a dirty but not quick patch is written to workaround broken siginfo
174: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 175: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 176: (Unix PID);
1.41 bertrand 177: - some OpenBSD's hacks are added;
178: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 179: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

181: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
1.39 bertrand 182: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 183: or freeaddrinfo;
1.39 bertrand 184: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
185: - major bug is fixed in CHR intrinsic when obtained character is not printable;
186: - Lapack is upgraded to 3.2.2;
1.37 bertrand 187: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
1.36 bertrand 188: - TOKENIZE is now able to convert escape sequences;
189: - ATPOKE and CLRATPOKE new intrinsics are added;
190: - --enable-full-static configure flag is added. With this flag, mysql and
191: postgresql libraries are statically linked in rpl executable;
192: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 193: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 194: - units is upgraded to 1.88;
195: - another major bug is fixed in the same variable creation subroutine.
196: Level 0 and 1 variables adresses were swapped when a global variable masked
197: a name of RPL/2 routine;
1.35 bertrand 198: - major bug is fixed in global variable creation subroutine. When a global
199: variable was created and when a local variable existed with the same name,
200: computed address of global variable was wrong;
201: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
202: is forced in front of all libraries.
1.34 bertrand 203: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
204: - BACKTRACE intrinsic is added;
205: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
206: when this structure is included in IFERR/THEN/END structure and when an error is
207: caught;
208: - major bug is fixed in analyse() subroutine. When evaluation() returned error
209: in a compiled program, analyse() caught this error twice and randomly aborted
210: with a segmentation error;
211: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
212: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
213: signals;
214: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
215: matrix.
1.33 bertrand 216: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
217: - minor bug is fixed in evaluation() subroutine. With this patch, same program
218: returns same result with or without -p flag;
219: - ncurses 5.7 is upgraded to 20100619;
220: - openssl is upgraded to 1.0.0a;

222: - debug memory allocation subroutines are improved to run in multithreaded
223: programs;
224: - some memory leaks are fixed in process management (SPAWN and DETACH);
225: - version verification is added to shared objects;
226: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
227: linux (false mremap() prototype);
228: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 229: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.29 bertrand 230: - all '-' are replaced by '_' in random generator list;

232: - major bug is fixed in IFERR structure. Only occurs in compiled program;
233: - major bug is fixed in copie_objet() and liberation(). Only concerns
234: format in FCH (file descriptor) and SCK (socket descriptor);
235: - debug routines are improved;
236: - PROCID is added;
237: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
238: and to not use swap;
1.26 bertrand 239: - major bug is fixed in sql support. SQL connections were closed in all chield
240: process;
241: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
242: discovered in Solaris thread safe allocators (libmalloc and libumem) that
243: are first fit class allocators. Solaris libmtmalloc works better and is
244: a best fit class allocator but its performance is poor than ptmalloc3
245: performance;
1.24 bertrand 246: - major bug is fixed in ROW+ intrinsic (new row was not added where it
247: should);
248: - minor bugs are fixed in interruptions.c (semaphores values when error is
249: caught);
250: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
251: created by SPAWN;
252: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
253: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 254: - ONEXIT is renamed in ATEXIT;
255: - ONEXIT new intrinsic is added.
1.20 bertrand 256: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
257: - major bug is fixed in static and shared variables initialization subroutine.
258: This bug only occurs when RPL/2 tries to create a shared or static variable
259: from an expression;
260: - major bug is fixed in copie_etat_processus(). A field that contains
261: information about shared variable was not copied to new processus structure;
1.19 bertrand 262: - some little memory leaks are fixed in evaluation(), recherche_type() and
263: sequenceur(). They only occured when syntax error were caught;
264: - IMPLICIT causes execution error instead system error;
265: - Hurd support is improved but currently broken because Hurd does not support
266: SIG_INFO. Work in progress;
267: - OpenBSD specific support is removed from sources;
268: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 269: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

1.13 bertrand 308: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
309: - in formatted file, string format returned a variable length string even if
310: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 311: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 312: - keyed access files support is added. Currently, only formatted files are
313: supported;

353: Number of scalar operations per second and per core : 2383016
354:
355: - PULPRFL does not abort on BUG() but on execution error;
356: - TRIM, REPL and TOKENIZE are added;
357: - sockets options are now set before bind();
358: - shutdown() is added to all connected sockets;
359: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
360: list argument and inexistant elements).
361: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
362: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
363: signals sent to main process were not caught because DAEMON did not replace
364: old pid by new one;
365: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
366: evaluation when an error is reported from a subroutine in another subroutine.
367: For example, error was not caught in following program when it is executed with
368: -p option :
369: TEST << iferr TEST2 then end >>
370: TEST2 << 0 inv >>
371: - major bug is fixed in variable management. Some local variables were
372: seen as global ones;
373: - major bug is fixed in rplcore. Rplcore entered in dead lock when
374: script file contains a multibyte character;
375: - IN intrinsic is added;
376: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
377: returned false ;
378: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
379: programs;
380: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
381: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
382: strings were never closed;
383: - some bugs have been fixed in file management;
384: - RPL/2 can now be run on EBCDIC systems (OS/390);
385: - major bug is fixed in -A command line option (NULL character is missing);
386: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
387: made by blocks (1024 bytes). When an incomplete multibyte sequence is
388: encountered at end of block, subroutine aborts with an execution error;
389: - major bug is fixed in OPEN (TCP/IPv4 sockets).
390: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
391: - DISP now locks stdout;
392: - rpliconv is added to replace standard iconv provided by operating system.
393: Indeed, conversion between different encodages requires transliteration
394: that is not offered by some iconv utility;
395: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
396: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
397: not be found), SYSEVAL enters in a dead lock;
398: - fprintf is replaced by some functions that allow transliterations between
399: locales;
400: - '"' can now be used in strings ("\"");
401: - iconv is called with -c in preprocessor stage. It is done to write
402: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
403: - double free is fixed in liberation() (type SQL, only occurs when locale is
404: set);
405: - LOCALIZATION, UCASE and LCASE are added;
406: - major bug is fixed in EXIT intrinsic that was able to return a false
407: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
408: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
409: used in onLoading from shared library, USE was pushed on stack as algebraic
410: expression;
411: - libiconv is upgraded to 1.13.1;
412: - gnuplot is upgraded to 4.2.6;
413: - gsl is upgraded to 1.13.
414: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
415: - pipe() is overwritten by a macro to avoid a system error. Communication
416: between process are done with pipes and these pipes are managed by a
417: specific asynchrone thread. If a script try to create more threads than
418: management thread can destroy, you can quickly achieve maximum number of
419: opened files and pipe() shall return a system error. This macro tries to create
420: pipes. If pipe() function returns an error, macro waits and retries. If
421: number of retries is greater than a hardcoded value, macro returns an error;
422: - major bug (deadlock) is fixed in process and thread management. I hope
423: this bug shall be the last one;
424: - major bug is fixed in DET intrinsic (determinant was computed without LU
425: diagonalization);
426: - SWAPCNTXT is added;
427: - minor bug is fixed in Makefile.am (licences rule).
428: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
429: - some bugfixes are added in process management;
430: - all process management is rewritten to avoid usage of defunct process
431: or thread number;
432: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
433: was called before a pending interruption5 (SIGFSTOP), signal handler uses
434: a freed semaphore and corrupts heap;
435: - CLRERR is added to erase previous errors;
436: - ERRN and ERRM return exception message and number;
437: - major bug is fixed in interruptions.c. All signal are now bufferised
438: when semaphore_liste_threads is null to avoid deadlock. This bug only
439: occured when STOP was sent to a dying thread or process (when this thread or
440: process was running retrait_thread());
441: - matrix rank is computed before matrix inversion;
442: - file locks are added to stdin and stdout. stderr is not locked because
443: all messages written by signal handlers are sent to stderr;
444: - configure.in script is modified to test gcc version and avoid a bug in
445: gcc older than 4.4;
446: - some benchmarks have been done :

502: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
503: - FORTRAN 77 file management subroutines are rewritten in pure C due to
504: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
505: in some cases (gcc/gfortran/libc/OS and arch conjonction);
506: - a memory leak is fixed in REMOVE intrinsic;
507: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()

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

547: deadlock when a huge amount of threads is launched);
548: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
549: arguments types are unsupported;
550: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
551: data are buffered. PLOT is used to draw these objects.);
552: - MARK instrinsic is added;

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

585: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
586: that all programs that worked with old SQL intrinsic can now work with
587: SQLQUERY. With all new programs, you can open a real connection to databases;
588: - NRPROC is added. This new intrinsic is used to catch error from child
589: process. Without NRPROC, any errors returned by child process cause
590: main process to abort;
591: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
592: starts a new process). There are no mutexes in RPL/2 because all spawned process
593: use specific context. Nevertheless, shared variables and associated mutexes
594: should be added;

665: nullified lists;
666: - rplexternals.h is modified and improved;
667: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and
668: configure script.
669: * Mon Jun 23 2008 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.7 (RPL/2)

680: - FUSE, RFUSE and CLRFUSE have been added;
681: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
682: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
683: workaround for this major bug. Nevertheless, all others capabilities seems to
684: work fine;

726: { "mysql:iso-8859-1" "server" "database" ... };
727: - major bug is fixed un analyse_algebrique(). When DISP printed an algebraic
728: object, 'DISP()' was pushed in stack;
729: - same major bug is fixed in <, >, <=, >= and <>;
730: - major bug fixed in formateur() (segfault when a symbol is used without "'");
731: - major bug is fixed in DUPN intrinsic;
732: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
733: before starting interrupt evaluation;
734: - -f parameter is added when iconv is called;
735: - as old file program was bugged, a new option is added to configure script.
736: When configure is called with --disable-encoding-autodetection, make does not
737: try to detect source encoding. Please, do not use if RPL/2 can be built
738: without this option !
739: - new garbage collector (and more efficient) is written;
740: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
741: not support real time signals, RPL/2 cannot use multitasking functions;

889: - external wrapper (rplplot) is written to force usage of gnuplot provided
890: by RPL/2 if it is built during build process. If this build does not exist,
891: it tries to launch regular gnuplot;
892: - gnuplot is added to source tree to avoid some trouble between preinstalled
893: gnuplot and release used by RPL/2. This addition to source tree is

942: With STATIC, next variables created by '->' are static;
943: - PROTECT and UNPROTECT are added to protect variables against write
944: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
945: versions of PROTECT and UNPROTECT that only deal with global variables
946: (see RCL/SAVE);
947: - variable management routines have been rewritten. The new ones are
948: uncompatible with the old ones. Before these changes, a local variable
949: was exported to a child subroutine, but cannot be modified into this
950: child subroutine. Now, a local variable is accessible only in its subroutine;
951: - SAVE intrinsic is added to manipulate global variables;

1272: fine...);
1273: - NOT is not correctly formatted in formateur.c:
1274: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1275: with a NOTZ function !
1276: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1279: - RPL/2 is tested with efence and valgrind;
1280: - configure.in script is modified;
1281: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1282: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1342: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1343: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1344: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1361: - SCLS is added;
1362: - DRWS now uses COLS to draw 2D graphics;
1363: - PPAR and SPAR are written. SPAR returns a list that contains the
1364: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1365: statistical variable, or "DISABLED" if its type is not one of the type of
1366: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1367: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1368: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1369: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1370: disabled. Arguments of EXTERNAL are case sensitive because the external
1371: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1372: of known external functions but add the new list to the last. { "all" }
1373: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1374: external names of the known functions;
1375: - mkrplso.in is modified.
1376: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1377: - vim syntax file is upgraded;
1378: - a minor mistake is fixed in recherche_instruction_suivante();
1379: - some minor memory leaks are fixed in recherche_type() function. They only

1388: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1389: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1390: VISIT does not find a name in level 1;
1391: - configure.in script is modified to add a new test (--enable-debug
1392: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1393: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1394: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1395: 'MATRIX' { 2 2 3 } GETR;
1396: - LOGSCALE intrinsic is improved and now, it can be used as
1397: { "main" "auxiliary" X Y } LOGSCALE;
1398: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1399: same than AXES:
1400: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1401: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1402: { { -10 10 } "automatic" } SCALE.
1403: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1404: because it changes only the dimension of the screen. To have a logarithmic
1405: scale, you must use LOGSCALE intrinsic:
1406: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1407: screen on second scale;
1408: - { X X } autoscale and { Y Y } logscale are now invalid;
1409: - *D is added (depth multiplication, for 3D graphics);
1410: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1411: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1412: - a major bug is fixed in GETI instrinsic when it is used with a name
1413: that contains a matrix or a vector (bad upper bounds conditions in
1414: incrementation);
1415: - DISP intrinsic now uses the 33-th flag. When it is not set
1416: (default), a final carriage return is sent to the terminal;
1417: - AXES intrinsic only takes a list that can contains the keywork
1418: "main" or "auxiliary". Before this modification, this keyword was in
1419: the first stack level;
1420: - vim syntax file is upgraded;
1421: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1422: option;
1423: - LAST is now disabled in the main loop of INT intrinsic;
1424: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1425: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1426: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1427: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1428: in 0);
1429: - LAST is disabled in the main loop of DRAW intrinsic;
1430: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1431: evaluation of an equation, the system stack is returned corrupted to the
1432: sequencer;
1433: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1434: of a loop are not integer or real.
1435: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1436: - the compilation stage aborts with an error message when two definitions
1437: have the same name. To improve the compilation() subroutine, I have to
1438: add some tests in gestion_variables.c;
1439: - recherche_type() subroutine ad some other connex subroutines are improved.
1440: Now, some syntax errors about object are caught and do not perform sequencer
1441: hangup;
1442: - readline is upgraded (minor compilation bug with recent gcc);
1443: - Makefile.am's and configure.in scripts are improved.
1444: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1445: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1446: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1447: the boxwidth, 1 by default);
1448: - recherche_type() is rewritten to be faster;
1449: - gsl is upgraded (release 1.3);
1450: - ncurses is upgraded and patched (release 5.3);
1451: - recherche_instruction_suivante() is fixed (string research with included
1452: '"') and rewritten to be faster;
1453: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1454: segfault.
1455: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)
1456: - RPL/2 is compiled by gcc-3.2.2 and seems to work;
1457: - the same minor bug is fixed in REDRAW and DRAX functions;
1458: - a minor fix is written in DRAW function (2D and 3D);

1463: - a minor bug is fixed in evaluation subroutine;
1464: - vim syntax file is improved;
1465: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1466: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1467: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1468: is a quick and dirty workaround...);
