29: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
30: - major bug is fixed in STD format (1E7 sq prints 1);
31: - major bug is fixed in READ intrinsic (socket). This bug was introduced
32: by a new feature in glibc.
33: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
34: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
35: "ALL" IMPLICIT when it runs in interactive mode;
36: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
37: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
38: to use SAVE to manipulate global variables;
39: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
40: subroutines;
41: - fix major memory access violation in evaluation subroutine. Only occurs
42: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
43: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
44: when X was a vector or a table.

1.57 bertrand 63: - Lapack is upgraded to 3.3.0;
1.58 bertrand 64: - libmtmalloc is now default Solaris allocator;
1.56 bertrand 65: - ncurses is upgraded;
1.60 bertrand 66: - regression introduced by 4.0.19 is fixed in signal management.
1.59 bertrand 67: Interruption1() could be called from itself and raises bus error (on sparc) or
1.55 bertrand 68: segmentation fault;
69: - sqlite is upgraded to 3.7.4;
1.54 bertrand 70: - OpenSSL is upgraded to 1.0.0c;

1.53 bertrand 73: - gnuplot is upgraded to 4.4.2 due to major bugs.
1.52 bertrand 74: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
75: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
76: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
77: corruption. As internal memory management have been improved, a best fit
78: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 79: - gnuplot is upgraded to 4.4.1;
80: - deadlock is fixed in signal handlers: same mutex was used in standard
81: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
82: and signal handlers. A new signal handler specific mutex is added;
83: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
84: that has to be evaluated by ->NUM;
1.49 bertrand 85: - rplfile build process is modify to be sure that rplfile is not modified
86: after rpl build stage (to be sure that rplfile checksum is not modified after
87: rpl compilation);
1.51 bertrand 88: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
89: modified to remove yacc code and renamed;
1.47 bertrand 90: - some workarounds have been written to not use buggy klibc SystemV IPCS.
91: ABORT now works on eComStation;
92: - sqlite is upgraded to 3.7.2;
93: - bug is fixed in software interrupts. When both process have different PID,
94: parent process was not interrupted if it is not group master process. To fix
95: this bug, SIGINJECT signal is not sent by child process but by control thread
96: in parent process;
1.46 bertrand 97: - minor bug is fixed in data injection (POKE) that does not work as expected
98: when child process is protected by NRPROC.
1.44 bertrand 99: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 100: - --enable-sysv-sems is added to configure script to use SystemV semaphores
101: functions instead of POSIX functions. This function is disabled or forced on
102: systems that does not provide correct POSIX or SysV semaphores subsystem;
103: - a dirty but not quick patch is written to workaround broken siginfo
104: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 105: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 106: (Unix PID);
1.41 bertrand 107: - some OpenBSD's hacks are added;
108: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 109: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
110: - random generator is cloned by SPAWN;
111: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
1.39 bertrand 112: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 113: or freeaddrinfo;
1.39 bertrand 114: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
115: - major bug is fixed in CHR intrinsic when obtained character is not printable;

122: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 123: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 124: - units is upgraded to 1.88;
125: - another major bug is fixed in the same variable creation subroutine.
126: Level 0 and 1 variables adresses were swapped when a global variable masked
127: a name of RPL/2 routine;
1.35 bertrand 128: - major bug is fixed in global variable creation subroutine. When a global
129: variable was created and when a local variable existed with the same name,
130: computed address of global variable was wrong;
131: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
132: is forced in front of all libraries.
1.34 bertrand 133: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
134: - BACKTRACE intrinsic is added;
135: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
136: when this structure is included in IFERR/THEN/END structure and when an error is
137: caught;
138: - major bug is fixed in analyse() subroutine. When evaluation() returned error
139: in a compiled program, analyse() caught this error twice and randomly aborted
140: with a segmentation error;
141: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
142: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
143: signals;
144: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
145: matrix.
1.33 bertrand 146: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
147: - minor bug is fixed in evaluation() subroutine. With this patch, same program

156: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
157: linux (false mremap() prototype);
158: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 159: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.29 bertrand 160: - all '-' are replaced by '_' in random generator list;
1.28 bertrand 161: - minor memory leak is fixed in OPEN intrinsic (socket);
162: - major bug is fixed in IFERR structure. Only occurs in compiled program;

164: format in FCH (file descriptor) and SCK (socket descriptor);
165: - debug routines are improved;
166: - PROCID is added;
167: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
168: and to not use swap;
1.26 bertrand 169: - major bug is fixed in sql support. SQL connections were closed in all chield
170: process;
171: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
172: discovered in Solaris thread safe allocators (libmalloc and libumem) that
173: are first fit class allocators. Solaris libmtmalloc works better and is
174: a best fit class allocator but its performance is poor than ptmalloc3
175: performance;
1.24 bertrand 176: - major bug is fixed in ROW+ intrinsic (new row was not added where it
177: should);
178: - minor bugs are fixed in interruptions.c (semaphores values when error is
179: caught);
180: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
181: created by SPAWN;
182: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
183: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 184: - ONEXIT is renamed in ATEXIT;
185: - ONEXIT new intrinsic is added.
1.20 bertrand 186: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
187: - major bug is fixed in static and shared variables initialization subroutine.
188: This bug only occurs when RPL/2 tries to create a shared or static variable
189: from an expression;
190: - major bug is fixed in copie_etat_processus(). A field that contains
191: information about shared variable was not copied to new processus structure;
1.19 bertrand 192: - some little memory leaks are fixed in evaluation(), recherche_type() and
193: sequenceur(). They only occured when syntax error were caught;
194: - IMPLICIT causes execution error instead system error;
195: - Hurd support is improved but currently broken because Hurd does not support
196: SIG_INFO. Work in progress;
197: - OpenBSD specific support is removed from sources;
198: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 199: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

234: Makefiles;
1.15 bertrand 235: - -a command line option analyzes program (structure and syntax) and
236: sends preprocessor output to standard output. This option is used by
237: rplc (RPL/2 compiler).
1.13 bertrand 238: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
239: - in formatted file, string format returned a variable length string even if
240: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 241: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 242: - keyed access files support is added. Currently, only formatted files are
243: supported;
244: - direct access files support is added. Currenlty, these files can only be used
245: in formatted mode;

1.12 bertrand 250: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
251: each execution (md5 and sha1 sums) to enhance security. If one of these tools
252: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
253: on a non recoverable system error;
254: - openssl and sqlite3 libraries are added;
255: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
256: variable indicates RPL/2 root directory. If it is not set, root path
257: is given by configure script (d_exec_path);
1.11 bertrand 258: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

283: Number of scalar operations per second and per core : 2383016
284:
285: - PULPRFL does not abort on BUG() but on execution error;
286: - TRIM, REPL and TOKENIZE are added;
287: - sockets options are now set before bind();
288: - shutdown() is added to all connected sockets;
289: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
290: list argument and inexistant elements).
291: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
292: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
293: signals sent to main process were not caught because DAEMON did not replace
294: old pid by new one;
295: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
296: evaluation when an error is reported from a subroutine in another subroutine.
297: For example, error was not caught in following program when it is executed with
298: -p option :
299: TEST << iferr TEST2 then end >>
300: TEST2 << 0 inv >>
301: - major bug is fixed in variable management. Some local variables were
302: seen as global ones;
303: - major bug is fixed in rplcore. Rplcore entered in dead lock when
304: script file contains a multibyte character;
305: - IN intrinsic is added;
306: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
307: returned false ;
308: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
309: programs;
310: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
311: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
312: strings were never closed;
313: - some bugs have been fixed in file management;

315: - major bug is fixed in -A command line option (NULL character is missing);
316: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
317: made by blocks (1024 bytes). When an incomplete multibyte sequence is
318: encountered at end of block, subroutine aborts with an execution error;
319: - major bug is fixed in OPEN (TCP/IPv4 sockets).
320: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
321: - DISP now locks stdout;
322: - rpliconv is added to replace standard iconv provided by operating system.
323: Indeed, conversion between different encodages requires transliteration
324: that is not offered by some iconv utility;
325: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
326: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
327: not be found), SYSEVAL enters in a dead lock;
328: - fprintf is replaced by some functions that allow transliterations between
329: locales;
330: - '"' can now be used in strings ("\"");
331: - iconv is called with -c in preprocessor stage. It is done to write
332: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
333: - double free is fixed in liberation() (type SQL, only occurs when locale is
334: set);
335: - LOCALIZATION, UCASE and LCASE are added;
336: - major bug is fixed in EXIT intrinsic that was able to return a false
337: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
338: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
339: used in onLoading from shared library, USE was pushed on stack as algebraic
340: expression;
341: - libiconv is upgraded to 1.13.1;
342: - gnuplot is upgraded to 4.2.6;
343: - gsl is upgraded to 1.13.
344: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
345: - pipe() is overwritten by a macro to avoid a system error. Communication
346: between process are done with pipes and these pipes are managed by a
347: specific asynchrone thread. If a script try to create more threads than
348: management thread can destroy, you can quickly achieve maximum number of
349: opened files and pipe() shall return a system error. This macro tries to create
350: pipes. If pipe() function returns an error, macro waits and retries. If
351: number of retries is greater than a hardcoded value, macro returns an error;
352: - major bug (deadlock) is fixed in process and thread management. I hope
353: this bug shall be the last one;
354: - major bug is fixed in DET intrinsic (determinant was computed without LU
355: diagonalization);
356: - SWAPCNTXT is added;
357: - minor bug is fixed in Makefile.am (licences rule).
358: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
359: - some bugfixes are added in process management;
360: - all process management is rewritten to avoid usage of defunct process
361: or thread number;
362: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
363: was called before a pending interruption5 (SIGFSTOP), signal handler uses
364: a freed semaphore and corrupts heap;
365: - CLRERR is added to erase previous errors;
366: - ERRN and ERRM return exception message and number;
367: - major bug is fixed in interruptions.c. All signal are now bufferised
368: when semaphore_liste_threads is null to avoid deadlock. This bug only
369: occured when STOP was sent to a dying thread or process (when this thread or
370: process was running retrait_thread());
371: - matrix rank is computed before matrix inversion;
372: - file locks are added to stdin and stdout. stderr is not locked because
373: all messages written by signal handlers are sent to stderr;
374: - configure.in script is modified to test gcc version and avoid a bug in
375: gcc older than 4.4;
376: - some benchmarks have been done :

415: to be used in signal handlers;
416: - major bug (memory corruption) is fixed in COL- intrinsic;
417: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
418: software interrupt was caught;

420: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
421: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
422: process termination);
423: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
424: its parent);
425: - a mutex to protect fork() syscall is added;

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

477: deadlock when a huge amount of threads is launched);
478: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
479: arguments types are unsupported;
480: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

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

516: that all programs that worked with old SQL intrinsic can now work with
517: SQLQUERY. With all new programs, you can open a real connection to databases;
518: - NRPROC is added. This new intrinsic is used to catch error from child
519: process. Without NRPROC, any errors returned by child process cause
520: main process to abort;
521: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
522: starts a new process). There are no mutexes in RPL/2 because all spawned process
523: use specific context. Nevertheless, shared variables and associated mutexes
524: should be added;

664: - -f parameter is added when iconv is called;
665: - as old file program was bugged, a new option is added to configure script.
666: When configure is called with --disable-encoding-autodetection, make does not
667: try to detect source encoding. Please, do not use if RPL/2 can be built
668: without this option !
669: - new garbage collector (and more efficient) is written;

673: - -p option is added. With this option, all scripts are compiled before
674: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
675: 40% faster;
676: - read and write operations in pipe() are rewritten to be sure that such
677: operations are atomic;

819: - external wrapper (rplplot) is written to force usage of gnuplot provided
820: by RPL/2 if it is built during build process. If this build does not exist,
821: it tries to launch regular gnuplot;
822: - gnuplot is added to source tree to avoid some trouble between preinstalled
823: gnuplot and release used by RPL/2. This addition to source tree is
824: required by some incompatibility between gnuplot releases;
825: - Lapack is upgraded to 3.1.1 release;
826: - GSL is upgraded to 1.9 revision;

872: With STATIC, next variables created by '->' are static;
873: - PROTECT and UNPROTECT are added to protect variables against write
874: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
875: versions of PROTECT and UNPROTECT that only deal with global variables
876: (see RCL/SAVE);
877: - variable management routines have been rewritten. The new ones are
878: uncompatible with the old ones. Before these changes, a local variable
879: was exported to a child subroutine, but cannot be modified into this
880: child subroutine. Now, a local variable is accessible only in its subroutine;
881: - SAVE intrinsic is added to manipulate global variables;

1202: fine...);
1203: - NOT is not correctly formatted in formateur.c:
1204: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1205: with a NOTZ function !
1206: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1207: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1209: - RPL/2 is tested with efence and valgrind;
1210: - configure.in script is modified;
1211: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1272: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1273: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1274: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1291: - SCLS is added;
1292: - DRWS now uses COLS to draw 2D graphics;
1293: - PPAR and SPAR are written. SPAR returns a list that contains the
1294: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1295: statistical variable, or "DISABLED" if its type is not one of the type of
1296: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1297: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1298: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1299: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1300: disabled. Arguments of EXTERNAL are case sensitive because the external
1301: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1302: of known external functions but add the new list to the last. { "all" }
1303: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1304: external names of the known functions;
1305: - mkrplso.in is modified.
1306: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1307: - vim syntax file is upgraded;
1308: - a minor mistake is fixed in recherche_instruction_suivante();
1309: - some minor memory leaks are fixed in recherche_type() function. They only

1318: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1319: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1320: VISIT does not find a name in level 1;
1321: - configure.in script is modified to add a new test (--enable-debug
1322: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1323: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1324: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1325: 'MATRIX' { 2 2 3 } GETR;
1326: - LOGSCALE intrinsic is improved and now, it can be used as
1327: { "main" "auxiliary" X Y } LOGSCALE;
1328: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1329: same than AXES:
1330: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1331: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1332: { { -10 10 } "automatic" } SCALE.
1333: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1334: because it changes only the dimension of the screen. To have a logarithmic
1335: scale, you must use LOGSCALE intrinsic:
1336: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1337: screen on second scale;
1338: - { X X } autoscale and { Y Y } logscale are now invalid;
1339: - *D is added (depth multiplication, for 3D graphics);
1340: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1341: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1342: - a major bug is fixed in GETI instrinsic when it is used with a name
1343: that contains a matrix or a vector (bad upper bounds conditions in
1344: incrementation);
1345: - DISP intrinsic now uses the 33-th flag. When it is not set
1346: (default), a final carriage return is sent to the terminal;
1347: - AXES intrinsic only takes a list that can contains the keywork
1348: "main" or "auxiliary". Before this modification, this keyword was in
1349: the first stack level;
1350: - vim syntax file is upgraded;
1351: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1352: option;
1353: - LAST is now disabled in the main loop of INT intrinsic;
1354: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1355: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1356: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1357: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1358: in 0);
1359: - LAST is disabled in the main loop of DRAW intrinsic;
1360: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1361: evaluation of an equation, the system stack is returned corrupted to the
1362: sequencer;
1363: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1364: of a loop are not integer or real.
1365: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1366: - the compilation stage aborts with an error message when two definitions
1367: have the same name. To improve the compilation() subroutine, I have to
1368: add some tests in gestion_variables.c;
1369: - recherche_type() subroutine ad some other connex subroutines are improved.
1370: Now, some syntax errors about object are caught and do not perform sequencer
1371: hangup;

1373: - Makefile.am's and configure.in scripts are improved.
1374: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1375: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1376: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1377: the boxwidth, 1 by default);
1378: - recherche_type() is rewritten to be faster;
1379: - gsl is upgraded (release 1.3);
1380: - ncurses is upgraded and patched (release 5.3);
1381: - recherche_instruction_suivante() is fixed (string research with included
1382: '"') and rewritten to be faster;

1396: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1397: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1398: is a quick and dirty workaround...);
1399: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1400: - rplconvert is improved.

1482: deleted too!;
1483: - configure script is improved (and it seems to be good ;-) );

1511: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1512: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1513:
1514: Newton:[~/rpl/rpl] > time make install
1515: ...
1516: real 338m39.623s
1517: user 324m32.290s
