Annotation of rpl/ChangeLog, revision 1.44
1.44 ! bertrand 1: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 2: - --enable-sysv-sems is added to configure script to use SystemV semaphores
3: functions instead of POSIX functions. This function is disabled or forced on
4: systems that does not provide correct POSIX or SysV semaphores subsystem;
5: - a dirty but not quick patch is written to workaround broken siginfo
6: structures. This patch has been successfully tested. It uses a segment of
7: shared memory (SysV) and eleven semaphores (Posix or SysV) by process
8: (Unix PID);
1.41 bertrand 9: - some OpenBSD's hacks are added;
10: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 11: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
12: - random generator is cloned by SPAWN;
13: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
1.39 bertrand 14: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 15: or freeaddrinfo;
1.39 bertrand 16: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
17: - major bug is fixed in CHR intrinsic when obtained character is not printable;
18: - Lapack is upgraded to 3.2.2;
1.37 bertrand 19: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
1.36 bertrand 20: - TOKENIZE is now able to convert escape sequences;
21: - ATPOKE and CLRATPOKE new intrinsics are added;
22: - --enable-full-static configure flag is added. With this flag, mysql and
23: postgresql libraries are statically linked in rpl executable;
24: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 25: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 26: - units is upgraded to 1.88;
27: - another major bug is fixed in the same variable creation subroutine.
28: Level 0 and 1 variables adresses were swapped when a global variable masked
29: a name of RPL/2 routine;
1.35 bertrand 30: - major bug is fixed in global variable creation subroutine. When a global
31: variable was created and when a local variable existed with the same name,
32: computed address of global variable was wrong;
33: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
34: is forced in front of all libraries.
1.34 bertrand 35: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
36: - BACKTRACE intrinsic is added;
37: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
38: when this structure is included in IFERR/THEN/END structure and when an error is
39: caught;
40: - major bug is fixed in analyse() subroutine. When evaluation() returned error
41: in a compiled program, analyse() caught this error twice and randomly aborted
42: with a segmentation error;
43: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
44: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
45: signals;
46: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
47: matrix.
1.33 bertrand 48: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

55: programs;
56: - some memory leaks are fixed in process management (SPAWN and DETACH);
57: - version verification is added to shared objects;
58: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
59: linux (false mremap() prototype);
60: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 61: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.29 bertrand 62: - all '-' are replaced by '_' in random generator list;
1.28 bertrand 63: - minor memory leak is fixed in OPEN intrinsic (socket);
64: - major bug is fixed in IFERR structure. Only occurs in compiled program;
65: - major bug is fixed in copie_objet() and liberation(). Only concerns
66: format in FCH (file descriptor) and SCK (socket descriptor);
67: - debug routines are improved;
68: - PROCID is added;
69: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
70: and to not use swap;
1.26 bertrand 71: - major bug is fixed in sql support. SQL connections were closed in all chield
72: process;
73: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
74: discovered in Solaris thread safe allocators (libmalloc and libumem) that
75: are first fit class allocators. Solaris libmtmalloc works better and is
76: a best fit class allocator but its performance is poor than ptmalloc3
77: performance;
1.24 bertrand 78: - major bug is fixed in ROW+ intrinsic (new row was not added where it
79: should);
80: - minor bugs are fixed in interruptions.c (semaphores values when error is
81: caught);
82: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
83: created by SPAWN;
84: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
85: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 86: - ONEXIT is renamed in ATEXIT;
87: - ONEXIT new intrinsic is added.
1.20 bertrand 88: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
89: - major bug is fixed in static and shared variables initialization subroutine.
90: This bug only occurs when RPL/2 tries to create a shared or static variable
91: from an expression;
92: - major bug is fixed in copie_etat_processus(). A field that contains
93: information about shared variable was not copied to new processus structure;
1.19 bertrand 94: - some little memory leaks are fixed in evaluation(), recherche_type() and
95: sequenceur(). They only occured when syntax error were caught;
96: - IMPLICIT causes execution error instead system error;
97: - Hurd support is improved but currently broken because Hurd does not support
98: SIG_INFO. Work in progress;
99: - OpenBSD specific support is removed from sources;
100: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 101: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)
102: - implicit names can now be disabled by new IMPLICIT intrinsic:

136: Makefiles;
1.15 bertrand 137: - -a command line option analyzes program (structure and syntax) and
138: sends preprocessor output to standard output. This option is used by
139: rplc (RPL/2 compiler).
1.13 bertrand 140: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
141: - in formatted file, string format returned a variable length string even if
142: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 143: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 144: - keyed access files support is added. Currently, only formatted files are
145: supported;
146: - direct access files support is added. Currenlty, these files can only be used
147: in formatted mode;
148: - virtual variables are now writte in UTF-8 and all special characters
149: in string are escaped;
1.12 bertrand 150: - all formatted files are now converted into UTF-8;

1.12 bertrand 152: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
153: each execution (md5 and sha1 sums) to enhance security. If one of these tools
154: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
155: on a non recoverable system error;
156: - openssl and sqlite3 libraries are added;
157: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
158: variable indicates RPL/2 root directory. If it is not set, root path
159: is given by configure script (d_exec_path);
1.11 bertrand 160: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
161: - configure.in and makefile.am's are modified to add Cygwin support. Interix

174: avoid a minor bug in EDIT and VISIT intrinsics;
1.4 bertrand 175: - minor bug is fixed in formateur_reel();
1.7 bertrand 176: - file-5.03 is patched to avoid bus error on systems that require memory
1.3 bertrand 177: alignment;
1.2 bertrand 178: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
179: were able to be avoided by evaluation routine.
1.1 bertrand 180: * Tue Jan 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.9 (RPL/2)

185: Number of scalar operations per second and per core : 2383016
186:
187: - PULPRFL does not abort on BUG() but on execution error;
188: - TRIM, REPL and TOKENIZE are added;
189: - sockets options are now set before bind();
190: - shutdown() is added to all connected sockets;
191: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
192: list argument and inexistant elements).
193: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
194: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
195: signals sent to main process were not caught because DAEMON did not replace
196: old pid by new one;
197: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
198: evaluation when an error is reported from a subroutine in another subroutine.
199: For example, error was not caught in following program when it is executed with
200: -p option :
201: TEST << iferr TEST2 then end >>
202: TEST2 << 0 inv >>
203: - major bug is fixed in variable management. Some local variables were
204: seen as global ones;
205: - major bug is fixed in rplcore. Rplcore entered in dead lock when
206: script file contains a multibyte character;
207: - IN intrinsic is added;
208: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
209: returned false ;
210: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
211: programs;
212: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
213: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
214: strings were never closed;
215: - some bugs have been fixed in file management;
216: - RPL/2 can now be run on EBCDIC systems (OS/390);
217: - major bug is fixed in -A command line option (NULL character is missing);
218: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
219: made by blocks (1024 bytes). When an incomplete multibyte sequence is
220: encountered at end of block, subroutine aborts with an execution error;
221: - major bug is fixed in OPEN (TCP/IPv4 sockets).
222: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
223: - DISP now locks stdout;
224: - rpliconv is added to replace standard iconv provided by operating system.
225: Indeed, conversion between different encodages requires transliteration
226: that is not offered by some iconv utility;
227: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
228: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
229: not be found), SYSEVAL enters in a dead lock;
230: - fprintf is replaced by some functions that allow transliterations between
231: locales;
232: - '"' can now be used in strings ("\"");
233: - iconv is called with -c in preprocessor stage. It is done to write
234: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
235: - double free is fixed in liberation() (type SQL, only occurs when locale is
236: set);
237: - LOCALIZATION, UCASE and LCASE are added;
238: - major bug is fixed in EXIT intrinsic that was able to return a false
239: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
240: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
241: used in onLoading from shared library, USE was pushed on stack as algebraic
242: expression;
243: - libiconv is upgraded to 1.13.1;
244: - gnuplot is upgraded to 4.2.6;
245: - gsl is upgraded to 1.13.
246: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
247: - pipe() is overwritten by a macro to avoid a system error. Communication
248: between process are done with pipes and these pipes are managed by a
249: specific asynchrone thread. If a script try to create more threads than
250: management thread can destroy, you can quickly achieve maximum number of
251: opened files and pipe() shall return a system error. This macro tries to create
252: pipes. If pipe() function returns an error, macro waits and retries. If
253: number of retries is greater than a hardcoded value, macro returns an error;
254: - major bug (deadlock) is fixed in process and thread management. I hope
255: this bug shall be the last one;
256: - major bug is fixed in DET intrinsic (determinant was computed without LU
257: diagonalization);
258: - SWAPCNTXT is added;
259: - minor bug is fixed in Makefile.am (licences rule).
260: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
261: - some bugfixes are added in process management;
262: - all process management is rewritten to avoid usage of defunct process
263: or thread number;
264: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
265: was called before a pending interruption5 (SIGFSTOP), signal handler uses
266: a freed semaphore and corrupts heap;
267: - CLRERR is added to erase previous errors;
268: - ERRN and ERRM return exception message and number;
269: - major bug is fixed in interruptions.c. All signal are now bufferised
270: when semaphore_liste_threads is null to avoid deadlock. This bug only
271: occured when STOP was sent to a dying thread or process (when this thread or
272: process was running retrait_thread());
273: - matrix rank is computed before matrix inversion;
274: - file locks are added to stdin and stdout. stderr is not locked because
275: all messages written by signal handlers are sent to stderr;
276: - configure.in script is modified to test gcc version and avoid a bug in
277: gcc older than 4.4;
278: - some benchmarks have been done :

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

330: - major bug is fixed in lecture_pipe when a nullified list is sent into a pipe;
331: - WORKDIR intrinsic is added;
332: - Level 0 variables are shared between all threads without copy. Indeed,
333: there variables are not modifiable and only contains static user definitions;
334: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
335: - FORTRAN 77 file management subroutines are rewritten in pure C due to
336: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
337: in some cases (gcc/gfortran/libc/OS and arch conjonction);
338: - a memory leak is fixed in REMOVE intrinsic;
339: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
340: and due to a libmysqlclient that is not thread safe).
341: * Wen Jun 10 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.2 (RPL/2)
342: - new enhanced allocator is written for regular variables, static variables and
343: shared variables;
344: - major bug is fixed in src/interruptions.c. This file did not compile
345: when SQL support was not enabled;
346: - new allocator is written for system stack and last stack;
347: - --enable-profile flag is added to configure script. When this flag is
348: enabled, rpl is built with -pg option;
349: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
350: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
351: process is killed;
352: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
353: know typeof() intrinsic function. This function is not standard but exists
354: under Sun Studio, gcc, and maybe some others compilers. If this function does
355: not exist on your compiler, you can change its definition by old one in
356: src/rpl.h;
357: - fflush() can now be interrupted by signal (SunOS);
358: - fflush(NULL) is called before all fork() occurrences;

384: - MARK instrinsic is added;
385: - new allocator mechanism is written;
386: - some regression bugs have been fixed, some memory leaks too.
387: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)

394: - YIELD intrinsic is added;
395: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
396: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
397: static variable that is shared by multiple threads;
398: - '->' intrinsic is improved. All object copies have been avoided;
399: - -n flag is added to catch HUP signal. stderr and stdout are redirected
400: to a file, stdin is redirected to /dev/null when control process is killed;
401: - a mutex is added to each object (before this modification,
402: RPL/2 used a global mutex and performances in multithreaded programs were very
403: poor.);
404: - ALARM is now interruptible;
405: - both PUT and PUTI intrinsics are improved and do not copy list and table
406: when nombre_occurrences == 1;

418: that all programs that worked with old SQL intrinsic can now work with
419: SQLQUERY. With all new programs, you can open a real connection to databases;
420: - NRPROC is added. This new intrinsic is used to catch error from child
421: process. Without NRPROC, any errors returned by child process cause
422: main process to abort;
423: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
424: starts a new process). There are no mutexes in RPL/2 because all spawned process
425: use specific context. Nevertheless, shared variables and associated mutexes
426: should be added;
427: - -D flag and DAEMONIZE intrinsic have been added;

567: - as old file program was bugged, a new option is added to configure script.
568: When configure is called with --disable-encoding-autodetection, make does not
569: try to detect source encoding. Please, do not use if RPL/2 can be built
570: without this option !
571: - new garbage collector (and more efficient) is written;

575: - -p option is added. With this option, all scripts are compiled before
576: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
577: 40% faster;
578: - read and write operations in pipe() are rewritten to be sure that such
579: operations are atomic;
580: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

721: - external wrapper (rplplot) is written to force usage of gnuplot provided
722: by RPL/2 if it is built during build process. If this build does not exist,
723: it tries to launch regular gnuplot;
724: - gnuplot is added to source tree to avoid some trouble between preinstalled
725: gnuplot and release used by RPL/2. This addition to source tree is
726: required by some incompatibility between gnuplot releases;
727: - Lapack is upgraded to 3.1.1 release;
728: - GSL is upgraded to 1.9 revision;

732: not writable;
733: - major regression is fixed in SYSEVAL intrinsic due to introduction of
734: error scrutation.

770: - VARS is modified to display variables status (LOCKED/UNLOCKED and
771: STATIC/VOLATILE/PARAMETER/VARIABLE);
772: - STATIC and VOLATILE intrinsics are added to specify static variables. A
773: static variable can be transformed into volatile with VOLATILE.
774: With STATIC, next variables created by '->' are static;
775: - PROTECT and UNPROTECT are added to protect variables against write
776: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
777: versions of PROTECT and UNPROTECT that only deal with global variables
778: (see RCL/SAVE);

1149: 2: integer (number of column to be inserted)
1150: 1: column matrix to be inserted;
1151: - major bug was discovered in interface_gnuplot(). It only occurs when

1160: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1161: - SLICESCALE intrinsic is added. Its syntax is
1162: { "automatic" nb_of_levels }
1163: { "discrete" l1 l2 l3 ... }
1164: { "incremental" start incr }
1165: { "incremental" start incr end }
1166: { "automatic" } (default);
1167: - a minor bug (in last stack) is fixed in AXES intrinsic
1168: - flag 52 is used to automatically update graphics;
1169: - man pages are updated;
1170: - evaluation() is modified to perform evaluation of expressions that contain
1171: '=';
1172: - a minor bug is fixed in AXES intrinsic;
1173: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1174: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1175: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1176: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1177: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1179: - C and H source files now include vim parameters;
1180: - vim syntax file is modified to include new intrinsics;
1181: - static archive is modified to include all required libraries needed by

1184: - '=' is added and tested;
1185: - XCOL and YCOL are added;
1186: - a minor bug in analyse_syntaxique() is fixed;
1187: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1188: structure. ELSE is modified to return an error when ELSE appears in
1189: an ELSE/END structure;
1190: - a major bug is fixed in CYCLE;
1191: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the

1193: - SCLS is added;
1194: - DRWS now uses COLS to draw 2D graphics;
1195: - PPAR and SPAR are written. SPAR returns a list that contains the
1196: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1197: statistical variable, or "DISABLED" if its type is not one of the type of
1198: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1199: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1200: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1201: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1202: disabled. Arguments of EXTERNAL are case sensitive because the external
1203: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1204: of known external functions but add the new list to the last. { "all" }
1205: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1206: external names of the known functions;
1207: - mkrplso.in is modified.
1208: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1209: - vim syntax file is upgraded;
1210: - a minor mistake is fixed in recherche_instruction_suivante();
1211: - some minor memory leaks are fixed in recherche_type() function. They only
1212: occurs when a syntax error is detected;

1219: - PUTC and PUTR new intrinsics are added.
1220: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1221: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1222: VISIT does not find a name in level 1;
1223: - configure.in script is modified to add a new test (--enable-debug
1224: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1225: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1226: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1227: 'MATRIX' { 2 2 3 } GETR;
1228: - LOGSCALE intrinsic is improved and now, it can be used as
1229: { "main" "auxiliary" X Y } LOGSCALE;
1230: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1231: same than AXES:
1232: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1233: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1234: { { -10 10 } "automatic" } SCALE.
1235: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1236: because it changes only the dimension of the screen. To have a logarithmic
1237: scale, you must use LOGSCALE intrinsic:
1238: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1239: screen on second scale;
1240: - { X X } autoscale and { Y Y } logscale are now invalid;
1241: - *D is added (depth multiplication, for 3D graphics);
1242: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1243: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1244: - a major bug is fixed in GETI instrinsic when it is used with a name
1245: that contains a matrix or a vector (bad upper bounds conditions in
1246: incrementation);
1247: - DISP intrinsic now uses the 33-th flag. When it is not set
1248: (default), a final carriage return is sent to the terminal;
1249: - AXES intrinsic only takes a list that can contains the keywork
1250: "main" or "auxiliary". Before this modification, this keyword was in
1251: the first stack level;
1252: - vim syntax file is upgraded;
1253: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1254: option;
1255: - LAST is now disabled in the main loop of INT intrinsic;
1256: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1257: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1258: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1259: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1260: in 0);
1261: - LAST is disabled in the main loop of DRAW intrinsic;
1262: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1263: evaluation of an equation, the system stack is returned corrupted to the
1264: sequencer;
1265: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1266: of a loop are not integer or real.
1267: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1277: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1278: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1298: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1299: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1300: is a quick and dirty workaround...);
1301: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1302: - rplconvert is improved.
