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

1.60 bertrand 64: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
65: - Ncurses is upgraded to 5.8;
66: - ALARM is fixed by filling isdst field;
67: - catch ECONNRESET in write intrinsic to return an execution error instead of
68: system one;

70: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;
1.57 bertrand 71: - Lapack is upgraded to 3.3.0;
1.58 bertrand 72: - libmtmalloc is now default Solaris allocator;
1.56 bertrand 73: - ncurses is upgraded;
1.60 bertrand 74: - regression introduced by 4.0.19 is fixed in signal management.
1.59 bertrand 75: Interruption1() could be called from itself and raises bus error (on sparc) or
1.55 bertrand 76: segmentation fault;
77: - sqlite is upgraded to 3.7.4;
1.54 bertrand 78: - OpenSSL is upgraded to 1.0.0c;

1.53 bertrand 81: - gnuplot is upgraded to 4.4.2 due to major bugs.
1.52 bertrand 82: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
83: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
84: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
85: corruption. As internal memory management have been improved, a best fit
86: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 87: - gnuplot is upgraded to 4.4.1;
88: - deadlock is fixed in signal handlers: same mutex was used in standard
89: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
90: and signal handlers. A new signal handler specific mutex is added;
91: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
92: that has to be evaluated by ->NUM;
1.49 bertrand 93: - rplfile build process is modify to be sure that rplfile is not modified
94: after rpl build stage (to be sure that rplfile checksum is not modified after
95: rpl compilation);
1.51 bertrand 96: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
97: modified to remove yacc code and renamed;
1.47 bertrand 98: - some workarounds have been written to not use buggy klibc SystemV IPCS.
99: ABORT now works on eComStation;
100: - sqlite is upgraded to 3.7.2;
101: - bug is fixed in software interrupts. When both process have different PID,
102: parent process was not interrupted if it is not group master process. To fix
103: this bug, SIGINJECT signal is not sent by child process but by control thread
104: in parent process;
1.46 bertrand 105: - minor bug is fixed in data injection (POKE) that does not work as expected
106: when child process is protected by NRPROC.
1.44 bertrand 107: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 108: - --enable-sysv-sems is added to configure script to use SystemV semaphores
109: functions instead of POSIX functions. This function is disabled or forced on
110: systems that does not provide correct POSIX or SysV semaphores subsystem;
111: - a dirty but not quick patch is written to workaround broken siginfo
112: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 113: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 114: (Unix PID);
1.41 bertrand 115: - some OpenBSD's hacks are added;
116: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 117: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

1.40 bertrand 121: or freeaddrinfo;
1.39 bertrand 122: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
123: - major bug is fixed in CHR intrinsic when obtained character is not printable;

129: postgresql libraries are statically linked in rpl executable;
130: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 131: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 132: - units is upgraded to 1.88;
133: - another major bug is fixed in the same variable creation subroutine.
134: Level 0 and 1 variables adresses were swapped when a global variable masked
135: a name of RPL/2 routine;
1.35 bertrand 136: - major bug is fixed in global variable creation subroutine. When a global
137: variable was created and when a local variable existed with the same name,
138: computed address of global variable was wrong;
139: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
140: is forced in front of all libraries.
1.34 bertrand 141: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
142: - BACKTRACE intrinsic is added;
143: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
144: when this structure is included in IFERR/THEN/END structure and when an error is
145: caught;
146: - major bug is fixed in analyse() subroutine. When evaluation() returned error
147: in a compiled program, analyse() caught this error twice and randomly aborted
148: with a segmentation error;
149: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
150: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
151: signals;
152: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
153: matrix.
1.33 bertrand 154: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
155: - minor bug is fixed in evaluation() subroutine. With this patch, same program

164: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
165: linux (false mremap() prototype);
166: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 167: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.29 bertrand 168: - all '-' are replaced by '_' in random generator list;
1.28 bertrand 169: - minor memory leak is fixed in OPEN intrinsic (socket);
170: - major bug is fixed in IFERR structure. Only occurs in compiled program;
171: - major bug is fixed in copie_objet() and liberation(). Only concerns
172: format in FCH (file descriptor) and SCK (socket descriptor);
173: - debug routines are improved;
174: - PROCID is added;
175: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
176: and to not use swap;
1.26 bertrand 177: - major bug is fixed in sql support. SQL connections were closed in all chield
178: process;
179: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
180: discovered in Solaris thread safe allocators (libmalloc and libumem) that
181: are first fit class allocators. Solaris libmtmalloc works better and is
182: a best fit class allocator but its performance is poor than ptmalloc3
183: performance;
1.24 bertrand 184: - major bug is fixed in ROW+ intrinsic (new row was not added where it
185: should);
186: - minor bugs are fixed in interruptions.c (semaphores values when error is
187: caught);
188: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
189: created by SPAWN;
190: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
191: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 192: - ONEXIT is renamed in ATEXIT;
193: - ONEXIT new intrinsic is added.
1.20 bertrand 194: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
195: - major bug is fixed in static and shared variables initialization subroutine.
196: This bug only occurs when RPL/2 tries to create a shared or static variable
197: from an expression;
198: - major bug is fixed in copie_etat_processus(). A field that contains
199: information about shared variable was not copied to new processus structure;
1.19 bertrand 200: - some little memory leaks are fixed in evaluation(), recherche_type() and
201: sequenceur(). They only occured when syntax error were caught;
202: - IMPLICIT causes execution error instead system error;
203: - Hurd support is improved but currently broken because Hurd does not support
204: SIG_INFO. Work in progress;
205: - OpenBSD specific support is removed from sources;
206: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 207: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

242: Makefiles;
1.15 bertrand 243: - -a command line option analyzes program (structure and syntax) and
244: sends preprocessor output to standard output. This option is used by
245: rplc (RPL/2 compiler).
1.13 bertrand 246: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
247: - in formatted file, string format returned a variable length string even if
248: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 249: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 250: - keyed access files support is added. Currently, only formatted files are
251: supported;
252: - direct access files support is added. Currenlty, these files can only be used
253: in formatted mode;

1.12 bertrand 258: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
259: each execution (md5 and sha1 sums) to enhance security. If one of these tools
260: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
261: on a non recoverable system error;
262: - openssl and sqlite3 libraries are added;
263: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
264: variable indicates RPL/2 root directory. If it is not set, root path
265: is given by configure script (d_exec_path);
1.11 bertrand 266: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

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

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

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

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

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

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

523: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
524: that all programs that worked with old SQL intrinsic can now work with
525: SQLQUERY. With all new programs, you can open a real connection to databases;
526: - NRPROC is added. This new intrinsic is used to catch error from child
527: process. Without NRPROC, any errors returned by child process cause
528: main process to abort;
529: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
530: starts a new process). There are no mutexes in RPL/2 because all spawned process
531: use specific context. Nevertheless, shared variables and associated mutexes
532: should be added;

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

681: - -p option is added. With this option, all scripts are compiled before
682: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
683: 40% faster;
684: - read and write operations in pipe() are rewritten to be sure that such
685: operations are atomic;
686: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

827: - external wrapper (rplplot) is written to force usage of gnuplot provided
828: by RPL/2 if it is built during build process. If this build does not exist,
829: it tries to launch regular gnuplot;
830: - gnuplot is added to source tree to avoid some trouble between preinstalled
831: gnuplot and release used by RPL/2. This addition to source tree is
832: required by some incompatibility between gnuplot releases;

882: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
883: versions of PROTECT and UNPROTECT that only deal with global variables
884: (see RCL/SAVE);
885: - variable management routines have been rewritten. The new ones are
886: uncompatible with the old ones. Before these changes, a local variable
887: was exported to a child subroutine, but cannot be modified into this
888: child subroutine. Now, a local variable is accessible only in its subroutine;
889: - SAVE intrinsic is added to manipulate global variables;

1210: fine...);
1211: - NOT is not correctly formatted in formateur.c:
1212: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1213: with a NOTZ function !
1214: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1217: - RPL/2 is tested with efence and valgrind;
1218: - configure.in script is modified;
1219: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1299: - SCLS is added;
1300: - DRWS now uses COLS to draw 2D graphics;
1301: - PPAR and SPAR are written. SPAR returns a list that contains the
1302: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1303: statistical variable, or "DISABLED" if its type is not one of the type of
1304: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1305: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1306: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1307: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1308: disabled. Arguments of EXTERNAL are case sensitive because the external
1309: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1310: of known external functions but add the new list to the last. { "all" }
1311: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1312: external names of the known functions;
1313: - mkrplso.in is modified.
1314: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1328: VISIT does not find a name in level 1;
1329: - configure.in script is modified to add a new test (--enable-debug
1330: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1331: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1332: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1333: 'MATRIX' { 2 2 3 } GETR;
1334: - LOGSCALE intrinsic is improved and now, it can be used as
1335: { "main" "auxiliary" X Y } LOGSCALE;
1336: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1337: same than AXES:
1338: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1339: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1340: { { -10 10 } "automatic" } SCALE.
1341: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1342: because it changes only the dimension of the screen. To have a logarithmic
1343: scale, you must use LOGSCALE intrinsic:
1344: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1345: screen on second scale;
1346: - { X X } autoscale and { Y Y } logscale are now invalid;
1347: - *D is added (depth multiplication, for 3D graphics);
1348: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1349: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1350: - a major bug is fixed in GETI instrinsic when it is used with a name
1351: that contains a matrix or a vector (bad upper bounds conditions in
1352: incrementation);
1353: - DISP intrinsic now uses the 33-th flag. When it is not set
1354: (default), a final carriage return is sent to the terminal;
1355: - AXES intrinsic only takes a list that can contains the keywork
1356: "main" or "auxiliary". Before this modification, this keyword was in
1357: the first stack level;
1358: - vim syntax file is upgraded;
1359: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1360: option;
1361: - LAST is now disabled in the main loop of INT intrinsic;
1362: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1363: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1364: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1365: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1366: in 0);
1367: - LAST is disabled in the main loop of DRAW intrinsic;
1368: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1369: evaluation of an equation, the system stack is returned corrupted to the
1370: sequencer;
1371: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1372: of a loop are not integer or real.
1373: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1374: - the compilation stage aborts with an error message when two definitions
1375: have the same name. To improve the compilation() subroutine, I have to
1376: add some tests in gestion_variables.c;
1377: - recherche_type() subroutine ad some other connex subroutines are improved.
1378: Now, some syntax errors about object are caught and do not perform sequencer
1379: hangup;
1380: - readline is upgraded (minor compilation bug with recent gcc);
1381: - Makefile.am's and configure.in scripts are improved.
1382: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1383: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1384: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1385: the boxwidth, 1 by default);
1386: - recherche_type() is rewritten to be faster;
1387: - gsl is upgraded (release 1.3);
1388: - ncurses is upgraded and patched (release 5.3);
1389: - recherche_instruction_suivante() is fixed (string research with included
1390: '"') and rewritten to be faster;

1404: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1405: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1406: is a quick and dirty workaround...);
1407: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1408: - rplconvert is improved.

1490: deleted too!;
1491: - configure script is improved (and it seems to be good ;-) );

1507: that the RPL/2 seqencer must stop and must give a prompt. This
1508: signal is an asynchonous "HALT" command;
1509: - SIGINT (CTRL+C) variables stack corruption is fixed;
1510: - IFERR seems to be fixed (in equation evaluation routine);

1519: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1520: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1521:
1522: Newton:[~/rpl/rpl] > time make install
1523: ...
1524: real 338m39.623s
1525: user 324m32.290s
