Annotation of rpl/ChangeLog, revision 1.52
1.52 ! bertrand 1: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
! 2: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
! 3: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
! 4: corruption. As internal memory management have been improved, a best fit
! 5: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 6: - gnuplot is upgraded to 4.4.1;
7: - deadlock is fixed in signal handlers: same mutex was used in standard
8: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
9: and signal handlers. A new signal handler specific mutex is added;
10: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
11: that has to be evaluated by ->NUM;
1.49 bertrand 12: - rplfile build process is modify to be sure that rplfile is not modified
13: after rpl build stage (to be sure that rplfile checksum is not modified after
14: rpl compilation);
1.51 bertrand 15: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
16: modified to remove yacc code and renamed;
1.47 bertrand 17: - some workarounds have been written to not use buggy klibc SystemV IPCS.
18: ABORT now works on eComStation;
19: - sqlite is upgraded to 3.7.2;
20: - bug is fixed in software interrupts. When both process have different PID,
21: parent process was not interrupted if it is not group master process. To fix
22: this bug, SIGINJECT signal is not sent by child process but by control thread
23: in parent process;
1.46 bertrand 24: - minor bug is fixed in data injection (POKE) that does not work as expected
25: when child process is protected by NRPROC.
1.44 bertrand 26: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 27: - --enable-sysv-sems is added to configure script to use SystemV semaphores
28: functions instead of POSIX functions. This function is disabled or forced on
29: systems that does not provide correct POSIX or SysV semaphores subsystem;
30: - a dirty but not quick patch is written to workaround broken siginfo
31: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 32: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 33: (Unix PID);
1.41 bertrand 34: - some OpenBSD's hacks are added;
35: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 36: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
37: - random generator is cloned by SPAWN;
38: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
1.39 bertrand 39: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 40: or freeaddrinfo;
1.39 bertrand 41: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
42: - major bug is fixed in CHR intrinsic when obtained character is not printable;
43: - Lapack is upgraded to 3.2.2;
1.37 bertrand 44: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
1.36 bertrand 45: - TOKENIZE is now able to convert escape sequences;
46: - ATPOKE and CLRATPOKE new intrinsics are added;
47: - --enable-full-static configure flag is added. With this flag, mysql and
48: postgresql libraries are statically linked in rpl executable;
49: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 50: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 51: - units is upgraded to 1.88;
52: - another major bug is fixed in the same variable creation subroutine.
53: Level 0 and 1 variables adresses were swapped when a global variable masked
54: a name of RPL/2 routine;
1.35 bertrand 55: - major bug is fixed in global variable creation subroutine. When a global
56: variable was created and when a local variable existed with the same name,
57: computed address of global variable was wrong;
58: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
59: is forced in front of all libraries.
1.34 bertrand 60: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
61: - BACKTRACE intrinsic is added;
62: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
63: when this structure is included in IFERR/THEN/END structure and when an error is
64: caught;
65: - major bug is fixed in analyse() subroutine. When evaluation() returned error
66: in a compiled program, analyse() caught this error twice and randomly aborted
67: with a segmentation error;
68: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
69: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
70: signals;
71: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
72: matrix.
1.33 bertrand 73: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

80: programs;
81: - some memory leaks are fixed in process management (SPAWN and DETACH);
82: - version verification is added to shared objects;
83: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
84: linux (false mremap() prototype);
85: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 86: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)

91: format in FCH (file descriptor) and SCK (socket descriptor);
92: - debug routines are improved;
93: - PROCID is added;
94: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
95: and to not use swap;
1.26 bertrand 96: - major bug is fixed in sql support. SQL connections were closed in all chield
97: process;
98: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
99: discovered in Solaris thread safe allocators (libmalloc and libumem) that
100: are first fit class allocators. Solaris libmtmalloc works better and is
101: a best fit class allocator but its performance is poor than ptmalloc3
102: performance;
1.24 bertrand 103: - major bug is fixed in ROW+ intrinsic (new row was not added where it
104: should);
105: - minor bugs are fixed in interruptions.c (semaphores values when error is
106: caught);
107: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
108: created by SPAWN;
109: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
110: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 111: - ONEXIT is renamed in ATEXIT;
112: - ONEXIT new intrinsic is added.
1.20 bertrand 113: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
114: - major bug is fixed in static and shared variables initialization subroutine.
115: This bug only occurs when RPL/2 tries to create a shared or static variable
116: from an expression;
117: - major bug is fixed in copie_etat_processus(). A field that contains
118: information about shared variable was not copied to new processus structure;
1.19 bertrand 119: - some little memory leaks are fixed in evaluation(), recherche_type() and
120: sequenceur(). They only occured when syntax error were caught;
121: - IMPLICIT causes execution error instead system error;
122: - Hurd support is improved but currently broken because Hurd does not support
123: SIG_INFO. Work in progress;
124: - OpenBSD specific support is removed from sources;
125: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 126: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

161: Makefiles;
1.15 bertrand 162: - -a command line option analyzes program (structure and syntax) and
163: sends preprocessor output to standard output. This option is used by
164: rplc (RPL/2 compiler).
1.13 bertrand 165: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
166: - in formatted file, string format returned a variable length string even if
167: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 168: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 169: - keyed access files support is added. Currently, only formatted files are
170: supported;
171: - direct access files support is added. Currenlty, these files can only be used
172: in formatted mode;
173: - virtual variables are now writte in UTF-8 and all special characters
174: in string are escaped;

1.12 bertrand 177: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
178: each execution (md5 and sha1 sums) to enhance security. If one of these tools
179: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
180: on a non recoverable system error;
181: - openssl and sqlite3 libraries are added;
182: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
183: variable indicates RPL/2 root directory. If it is not set, root path
184: is given by configure script (d_exec_path);
1.11 bertrand 185: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
186: - configure.in and makefile.am's are modified to add Cygwin support. Interix

199: avoid a minor bug in EDIT and VISIT intrinsics;
1.4 bertrand 200: - minor bug is fixed in formateur_reel();
1.7 bertrand 201: - file-5.03 is patched to avoid bus error on systems that require memory
1.3 bertrand 202: alignment;
1.2 bertrand 203: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
204: were able to be avoided by evaluation routine.
1.1 bertrand 205: * Tue Jan 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.9 (RPL/2)

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

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

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

354: - minor bug (double free corruption) is fixed in CLOSE intrinsic;
355: - major bug is fixed in lecture_pipe when a nullified list is sent into a pipe;
356: - WORKDIR intrinsic is added;
357: - Level 0 variables are shared between all threads without copy. Indeed,
358: there variables are not modifiable and only contains static user definitions;
359: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
360: - FORTRAN 77 file management subroutines are rewritten in pure C due to
361: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
362: in some cases (gcc/gfortran/libc/OS and arch conjonction);
363: - a memory leak is fixed in REMOVE intrinsic;
364: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
365: and due to a libmysqlclient that is not thread safe).
366: * Wen Jun 10 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.2 (RPL/2)
367: - new enhanced allocator is written for regular variables, static variables and
368: shared variables;
369: - major bug is fixed in src/interruptions.c. This file did not compile
370: when SQL support was not enabled;
371: - new allocator is written for system stack and last stack;
372: - --enable-profile flag is added to configure script. When this flag is
373: enabled, rpl is built with -pg option;
374: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
375: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
376: process is killed;
377: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
378: know typeof() intrinsic function. This function is not standard but exists
379: under Sun Studio, gcc, and maybe some others compilers. If this function does
380: not exist on your compiler, you can change its definition by old one in
381: src/rpl.h;
382: - fflush() can now be interrupted by signal (SunOS);
383: - fflush(NULL) is called before all fork() occurrences;

422: static variable that is shared by multiple threads;
423: - '->' intrinsic is improved. All object copies have been avoided;
424: - -n flag is added to catch HUP signal. stderr and stdout are redirected
425: to a file, stdin is redirected to /dev/null when control process is killed;
426: - a mutex is added to each object (before this modification,

443: that all programs that worked with old SQL intrinsic can now work with
444: SQLQUERY. With all new programs, you can open a real connection to databases;
445: - NRPROC is added. This new intrinsic is used to catch error from child
446: process. Without NRPROC, any errors returned by child process cause
447: main process to abort;
448: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
449: starts a new process). There are no mutexes in RPL/2 because all spawned process
450: use specific context. Nevertheless, shared variables and associated mutexes
451: should be added;

746: - external wrapper (rplplot) is written to force usage of gnuplot provided
747: by RPL/2 if it is built during build process. If this build does not exist,
748: it tries to launch regular gnuplot;
749: - gnuplot is added to source tree to avoid some trouble between preinstalled
750: gnuplot and release used by RPL/2. This addition to source tree is
751: required by some incompatibility between gnuplot releases;
752: - Lapack is upgraded to 3.1.1 release;
753: - GSL is upgraded to 1.9 revision;

1174: 2: integer (number of column to be inserted)
1175: 1: column matrix to be inserted;
1176: - major bug was discovered in interface_gnuplot(). It only occurs when

1185: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1186: - SLICESCALE intrinsic is added. Its syntax is
1187: { "automatic" nb_of_levels }
1188: { "discrete" l1 l2 l3 ... }
1189: { "incremental" start incr }
1190: { "incremental" start incr end }
1191: { "automatic" } (default);

1193: - flag 52 is used to automatically update graphics;
1194: - man pages are updated;
1195: - evaluation() is modified to perform evaluation of expressions that contain
1196: '=';
1197: - a minor bug is fixed in AXES intrinsic;
1198: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1199: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1200: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1201: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1202: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1218: - SCLS is added;
1219: - DRWS now uses COLS to draw 2D graphics;
1220: - PPAR and SPAR are written. SPAR returns a list that contains the
1221: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1222: statistical variable, or "DISABLED" if its type is not one of the type of
1223: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1224: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1225: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1226: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1227: disabled. Arguments of EXTERNAL are case sensitive because the external
1228: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1229: of known external functions but add the new list to the last. { "all" }
1230: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1231: external names of the known functions;
1232: - mkrplso.in is modified.
1233: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1234: - vim syntax file is upgraded;
1235: - a minor mistake is fixed in recherche_instruction_suivante();
1236: - some minor memory leaks are fixed in recherche_type() function. They only

1244: - PUTC and PUTR new intrinsics are added.
1245: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1246: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1247: VISIT does not find a name in level 1;
1248: - configure.in script is modified to add a new test (--enable-debug
1249: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1250: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1251: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1252: 'MATRIX' { 2 2 3 } GETR;
1253: - LOGSCALE intrinsic is improved and now, it can be used as
1254: { "main" "auxiliary" X Y } LOGSCALE;
1255: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1256: same than AXES:
1257: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1258: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1259: { { -10 10 } "automatic" } SCALE.
1260: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1261: because it changes only the dimension of the screen. To have a logarithmic
1262: scale, you must use LOGSCALE intrinsic:
1263: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1264: screen on second scale;
1265: - { X X } autoscale and { Y Y } logscale are now invalid;
1266: - *D is added (depth multiplication, for 3D graphics);
1267: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1268: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1269: - a major bug is fixed in GETI instrinsic when it is used with a name
1270: that contains a matrix or a vector (bad upper bounds conditions in
1271: incrementation);
1272: - DISP intrinsic now uses the 33-th flag. When it is not set
1273: (default), a final carriage return is sent to the terminal;
1274: - AXES intrinsic only takes a list that can contains the keywork
1275: "main" or "auxiliary". Before this modification, this keyword was in
1276: the first stack level;
1277: - vim syntax file is upgraded;
1278: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1279: option;
1280: - LAST is now disabled in the main loop of INT intrinsic;
1281: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1282: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1283: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1284: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1285: in 0);
1286: - LAST is disabled in the main loop of DRAW intrinsic;
1287: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1288: evaluation of an equation, the system stack is returned corrupted to the
1289: sequencer;
1290: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1291: of a loop are not integer or real.
1292: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1300: - Makefile.am's and configure.in scripts are improved.
1301: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1302: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1303: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1304: the boxwidth, 1 by default);
1305: - recherche_type() is rewritten to be faster;
1306: - gsl is upgraded (release 1.3);
1307: - ncurses is upgraded and patched (release 5.3);
1308: - recherche_instruction_suivante() is fixed (string research with included
1309: '"') and rewritten to be faster;

1320: - a minor bug is fixed in evaluation subroutine;
1321: - vim syntax file is improved;
1322: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1323: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1324: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1325: is a quick and dirty workaround...);
1326: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1327: - rplconvert is improved.
1328: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1344: Now, an expression such as 'A+' returns an error when it is analyzed;
1345: - VISIT intrinsic is added;
1346: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1347: normal mode.

1435: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1436: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1437: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1438: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1439: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1440:
1441: Newton:[~/rpl/rpl] > time make install
1442: ...
1443: real 338m39.623s
1444: user 324m32.290s
