62: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
63: - major bug is fixed in STD format (1E7 sq prints 1);
64: - major bug is fixed in READ intrinsic (socket). This bug was introduced
65: by a new feature in glibc.
66: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
67: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
68: "ALL" IMPLICIT when it runs in interactive mode;
69: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
70: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
71: to use SAVE to manipulate global variables;
72: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
73: subroutines;
74: - fix major memory access violation in evaluation subroutine. Only occurs
75: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
76: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
77: when X was a vector or a table.

90: - Ncurses is upgraded to 5.8;
91: - ALARM is fixed by filling isdst field;
92: - catch ECONNRESET in write intrinsic to return an execution error instead of
93: system one;
94: - fix a typo in HELP intrinsic;
95: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;
1.57 bertrand 96: - Lapack is upgraded to 3.3.0;
1.58 bertrand 97: - libmtmalloc is now default Solaris allocator;
1.56 bertrand 98: - ncurses is upgraded;
1.60 bertrand 99: - regression introduced by 4.0.19 is fixed in signal management.
1.59 bertrand 100: Interruption1() could be called from itself and raises bus error (on sparc) or
1.55 bertrand 101: segmentation fault;
102: - sqlite is upgraded to 3.7.4;
1.54 bertrand 103: - OpenSSL is upgraded to 1.0.0c;

1.53 bertrand 106: - gnuplot is upgraded to 4.4.2 due to major bugs.
1.52 bertrand 107: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
108: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
109: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
110: corruption. As internal memory management have been improved, a best fit
111: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 112: - gnuplot is upgraded to 4.4.1;
113: - deadlock is fixed in signal handlers: same mutex was used in standard
114: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
115: and signal handlers. A new signal handler specific mutex is added;
116: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
117: that has to be evaluated by ->NUM;
1.49 bertrand 118: - rplfile build process is modify to be sure that rplfile is not modified
119: after rpl build stage (to be sure that rplfile checksum is not modified after
120: rpl compilation);
1.51 bertrand 121: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
122: modified to remove yacc code and renamed;
1.47 bertrand 123: - some workarounds have been written to not use buggy klibc SystemV IPCS.
124: ABORT now works on eComStation;
125: - sqlite is upgraded to 3.7.2;
126: - bug is fixed in software interrupts. When both process have different PID,
127: parent process was not interrupted if it is not group master process. To fix
128: this bug, SIGINJECT signal is not sent by child process but by control thread
129: in parent process;
1.46 bertrand 130: - minor bug is fixed in data injection (POKE) that does not work as expected
131: when child process is protected by NRPROC.
1.44 bertrand 132: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 133: - --enable-sysv-sems is added to configure script to use SystemV semaphores
134: functions instead of POSIX functions. This function is disabled or forced on
135: systems that does not provide correct POSIX or SysV semaphores subsystem;
136: - a dirty but not quick patch is written to workaround broken siginfo
137: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 138: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 139: (Unix PID);
1.41 bertrand 140: - some OpenBSD's hacks are added;
141: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 142: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
143: - random generator is cloned by SPAWN;
144: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
1.39 bertrand 145: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 146: or freeaddrinfo;
1.39 bertrand 147: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
148: - major bug is fixed in CHR intrinsic when obtained character is not printable;

154: postgresql libraries are statically linked in rpl executable;
155: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 156: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 157: - units is upgraded to 1.88;
158: - another major bug is fixed in the same variable creation subroutine.
159: Level 0 and 1 variables adresses were swapped when a global variable masked
160: a name of RPL/2 routine;
1.35 bertrand 161: - major bug is fixed in global variable creation subroutine. When a global
162: variable was created and when a local variable existed with the same name,
163: computed address of global variable was wrong;
164: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
165: is forced in front of all libraries.
1.34 bertrand 166: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
167: - BACKTRACE intrinsic is added;
168: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
169: when this structure is included in IFERR/THEN/END structure and when an error is
170: caught;
171: - major bug is fixed in analyse() subroutine. When evaluation() returned error
172: in a compiled program, analyse() caught this error twice and randomly aborted
173: with a segmentation error;
174: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
175: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
176: signals;
177: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
178: matrix.
1.33 bertrand 179: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
180: - minor bug is fixed in evaluation() subroutine. With this patch, same program

189: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
190: linux (false mremap() prototype);
191: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 192: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.29 bertrand 193: - all '-' are replaced by '_' in random generator list;
1.28 bertrand 194: - minor memory leak is fixed in OPEN intrinsic (socket);
195: - major bug is fixed in IFERR structure. Only occurs in compiled program;
196: - major bug is fixed in copie_objet() and liberation(). Only concerns
197: format in FCH (file descriptor) and SCK (socket descriptor);
198: - debug routines are improved;
199: - PROCID is added;
200: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
201: and to not use swap;
1.26 bertrand 202: - major bug is fixed in sql support. SQL connections were closed in all chield
203: process;
204: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
205: discovered in Solaris thread safe allocators (libmalloc and libumem) that
206: are first fit class allocators. Solaris libmtmalloc works better and is
207: a best fit class allocator but its performance is poor than ptmalloc3
208: performance;
1.24 bertrand 209: - major bug is fixed in ROW+ intrinsic (new row was not added where it
210: should);
211: - minor bugs are fixed in interruptions.c (semaphores values when error is
212: caught);
213: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
214: created by SPAWN;
215: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
216: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 217: - ONEXIT is renamed in ATEXIT;
218: - ONEXIT new intrinsic is added.
1.20 bertrand 219: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
220: - major bug is fixed in static and shared variables initialization subroutine.
221: This bug only occurs when RPL/2 tries to create a shared or static variable
222: from an expression;
223: - major bug is fixed in copie_etat_processus(). A field that contains
224: information about shared variable was not copied to new processus structure;
1.19 bertrand 225: - some little memory leaks are fixed in evaluation(), recherche_type() and
226: sequenceur(). They only occured when syntax error were caught;
227: - IMPLICIT causes execution error instead system error;
228: - Hurd support is improved but currently broken because Hurd does not support
229: SIG_INFO. Work in progress;
230: - OpenBSD specific support is removed from sources;
231: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 232: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

325: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
326: signals sent to main process were not caught because DAEMON did not replace
327: old pid by new one;
328: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
329: evaluation when an error is reported from a subroutine in another subroutine.
330: For example, error was not caught in following program when it is executed with
331: -p option :
332: TEST << iferr TEST2 then end >>
333: TEST2 << 0 inv >>
334: - major bug is fixed in variable management. Some local variables were

356: Indeed, conversion between different encodages requires transliteration
357: that is not offered by some iconv utility;
358: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
359: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
360: not be found), SYSEVAL enters in a dead lock;
361: - fprintf is replaced by some functions that allow transliterations between
362: locales;
363: - '"' can now be used in strings ("\"");
364: - iconv is called with -c in preprocessor stage. It is done to write
365: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
366: - double free is fixed in liberation() (type SQL, only occurs when locale is
367: set);
368: - LOCALIZATION, UCASE and LCASE are added;
369: - major bug is fixed in EXIT intrinsic that was able to return a false
370: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
371: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
372: used in onLoading from shared library, USE was pushed on stack as algebraic
373: expression;
374: - libiconv is upgraded to 1.13.1;
375: - gnuplot is upgraded to 4.2.6;
376: - gsl is upgraded to 1.13.
377: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
378: - pipe() is overwritten by a macro to avoid a system error. Communication
379: between process are done with pipes and these pipes are managed by a
380: specific asynchrone thread. If a script try to create more threads than
381: management thread can destroy, you can quickly achieve maximum number of
382: opened files and pipe() shall return a system error. This macro tries to create
383: pipes. If pipe() function returns an error, macro waits and retries. If
384: number of retries is greater than a hardcoded value, macro returns an error;
385: - major bug (deadlock) is fixed in process and thread management. I hope
386: this bug shall be the last one;
387: - major bug is fixed in DET intrinsic (determinant was computed without LU
388: diagonalization);
389: - SWAPCNTXT is added;
390: - minor bug is fixed in Makefile.am (licences rule).
391: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
392: - some bugfixes are added in process management;
393: - all process management is rewritten to avoid usage of defunct process
394: or thread number;
395: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
396: was called before a pending interruption5 (SIGFSTOP), signal handler uses
397: a freed semaphore and corrupts heap;
398: - CLRERR is added to erase previous errors;
399: - ERRN and ERRM return exception message and number;
400: - major bug is fixed in interruptions.c. All signal are now bufferised
401: when semaphore_liste_threads is null to avoid deadlock. This bug only
402: occured when STOP was sent to a dying thread or process (when this thread or
403: process was running retrait_thread());
404: - matrix rank is computed before matrix inversion;
405: - file locks are added to stdin and stdout. stderr is not locked because
406: all messages written by signal handlers are sent to stderr;
407: - configure.in script is modified to test gcc version and avoid a bug in
408: gcc older than 4.4;
409: - some benchmarks have been done :

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

478: - --enable-profile flag is added to configure script. When this flag is
479: enabled, rpl is built with -pg option;
480: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
481: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
482: process is killed;
483: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
484: know typeof() intrinsic function. This function is not standard but exists
485: under Sun Studio, gcc, and maybe some others compilers. If this function does
486: not exist on your compiler, you can change its definition by old one in
487: src/rpl.h;
488: - fflush() can now be interrupted by signal (SunOS);
489: - fflush(NULL) is called before all fork() occurrences;

510: deadlock when a huge amount of threads is launched);
511: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
512: arguments types are unsupported;
513: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
514: data are buffered. PLOT is used to draw these objects.);
515: - MARK instrinsic is added;
516: - new allocator mechanism is written;
517: - some regression bugs have been fixed, some memory leaks too.
518: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)

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

548: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
549: that all programs that worked with old SQL intrinsic can now work with
550: SQLQUERY. With all new programs, you can open a real connection to databases;
551: - NRPROC is added. This new intrinsic is used to catch error from child
552: process. Without NRPROC, any errors returned by child process cause
553: main process to abort;
554: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
555: starts a new process). There are no mutexes in RPL/2 because all spawned process
556: use specific context. Nevertheless, shared variables and associated mutexes
557: should be added;
558: - -D flag and DAEMONIZE intrinsic have been added;

608: - ->TABLE and TABLE-> intrinsics are added;
609: - major bug is fixed in recherche_type(). Only occurs when rpl executes
610: precompiled scripts;

627: CRTAB new intrinsic creates a regular table. By default, all elements are
628: nullified lists;
629: - rplexternals.h is modified and improved;
630: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and

643: - FUSE, RFUSE and CLRFUSE have been added;
644: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
645: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
646: workaround for this major bug. Nevertheless, all others capabilities seems to
647: work fine;
648: - '->' is modified to return error when program tries to initialiaze two

696: before starting interrupt evaluation;
697: - -f parameter is added when iconv is called;
698: - as old file program was bugged, a new option is added to configure script.
699: When configure is called with --disable-encoding-autodetection, make does not
700: try to detect source encoding. Please, do not use if RPL/2 can be built
701: without this option !
702: - new garbage collector (and more efficient) is written;
703: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
704: not support real time signals, RPL/2 cannot use multitasking functions;
705: - error returned by preprocessor are now catched by RPL/2;
706: - -p option is added. With this option, all scripts are compiled before
707: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
708: 40% faster;
709: - read and write operations in pipe() are rewritten to be sure that such
710: operations are atomic;
711: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

738: greater than one second. On some systems, usleep argument must be lower
739: than 1E6;
740: - numeric and character formats are now tested;
741: - -A flag is added. -A is used to give command line parameters to main
742: routine. Example:

765: - socket support (Unix, IPv4, IPv6, STREAM, DATAGRAM, ROBUST DATAGRAM,
766: SEQUENTIAL DATAGRAM, RAW) is added. Warning: IPv6 sockets have not been tested
767: because I don't have any IPv6 compliant server, but they should work.
768: * Mon Sep 10 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.1 (RPL/2)
769: - library management is rewritten from scratch. EXTERNAL is removed and
770: EXTERNALS is added. Now, all exported symbols are sent to RPL/2 when
771: library is loaded;
772: - OPEN arguments are changed;
773: - EXTERNAL now checks availability of external functions;
774: - number of arguments is verified in analyse_algebrique().

789: - major bug is fixed in tex.h (multiline strings);
790: - examples subdir is added;
791: - major bug is fixed in recherche_variable(). When an expression is evaluated
792: in a function, all variables set in this function must be visible in
793: expression. Thus, << I -> 3 << << I >> eval >> must return 3, not 'I';
794: - LAST stack is saved in rplcore;
795: - major bug is fixed in ->HMS. It only occurs when argument type is not
796: integer or real;

813: * Tue Jul 17 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8x (RPL/2)
814: - major regression bug is fixed in PRINT due to mistake in latex pathes;
815: - gnuplot does not have to be built if --disable-embedded-gnuplot is set;
816: - new prompt ("RPL/2> ") is used for interactive mode;
817: - ARCCOS, ARCSIN, ARCTG, ARGCH, ARGSH, ARGTH, CH, SH, TH and TG intrinsics
818: are removed, because all of these intrinsics have two forms. ARCCOS is
819: the same than ACOS, TAN=TG, COSH=CH. Please adapt your scripts;
820: - gnuplot compilation does not have to be done when disable-gnuplot is set;
821: - major bug is fixed in RECV that avoid usage of multitasking.
822: * Tue Jul 10 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8w (RPL/2)

825: an algebraic expression;
826: - --enable-debug is modified. Now, return can be defined to print
827: on stdout its position in source code (line and function);
828: - minor bug is fixed in recherche_type(). Don't forget that space
829: are not significant in algebraic expression:
830: '12 3+ 12 X' is the same expression than '123+12X';
831: - src/Makefile.am is modified to avoid double compilation process;
832: - --enable-final-run-path is added to configure.in script;
833: - STATIC is modified to declare static variables in expression. Warning: static
834: variables used in expressions are deleted when evaluation of this expression
835: ends;
836: - MEM does not report static variable sizes;
837: - minor bug is fixed in HELP intrinsic. When the last instruction was not
838: known, HELP function was pushed in operational stack. HELP did not work
839: when there were space on input line.
840: * Mon May 28 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8v (RPL/2)

849: unsensitive. A minor bug is fixed in recherche_type() because all external
850: functions were case unsensitive when they were evaluated from RPN expressions;
851: - HELP function is rewritten to be more friendly (a la OpenVMS);
852: - external wrapper (rplplot) is written to force usage of gnuplot provided
853: by RPL/2 if it is built during build process. If this build does not exist,
854: it tries to launch regular gnuplot;
855: - gnuplot is added to source tree to avoid some trouble between preinstalled
856: gnuplot and release used by RPL/2. This addition to source tree is
857: required by some incompatibility between gnuplot releases;
858: - Lapack is upgraded to 3.1.1 release;
859: - GSL is upgraded to 1.9 revision;
860: - RPL_TMP_PATH env variable is added to specify the path of tempfiles. If
861: it is not set, /tmp is used. If /tmp is not writable, /var/tmp is used. If
862: not, ./ but RPL/2 can hang with a fatal error if this last location is
863: not writable;
864: - major regression is fixed in SYSEVAL intrinsic due to introduction of
865: error scrutation.

905: With STATIC, next variables created by '->' are static;
906: - PROTECT and UNPROTECT are added to protect variables against write
907: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
908: versions of PROTECT and UNPROTECT that only deal with global variables
909: (see RCL/SAVE);
910: - variable management routines have been rewritten. The new ones are
911: uncompatible with the old ones. Before these changes, a local variable
912: was exported to a child subroutine, but cannot be modified into this
913: child subroutine. Now, a local variable is accessible only in its subroutine;
914: - SAVE intrinsic is added to manipulate global variables;

1134: #!/usr/local/bin/rpl -c
1135:
1136: TEST
1137: <<
1138: 'X' indep

1235: fine...);
1236: - NOT is not correctly formatted in formateur.c:
1237: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1238: with a NOTZ function !
1239: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1242: - RPL/2 is tested with efence and valgrind;
1243: - configure.in script is modified;
1244: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1305: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1306: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1307: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1324: - SCLS is added;
1325: - DRWS now uses COLS to draw 2D graphics;
1326: - PPAR and SPAR are written. SPAR returns a list that contains the
1327: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1328: statistical variable, or "DISABLED" if its type is not one of the type of
1329: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1330: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1331: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1332: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1333: disabled. Arguments of EXTERNAL are case sensitive because the external
1334: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1335: of known external functions but add the new list to the last. { "all" }
1336: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1337: external names of the known functions;
1338: - mkrplso.in is modified.
1339: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1340: - vim syntax file is upgraded;
1341: - a minor mistake is fixed in recherche_instruction_suivante();

1352: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1353: VISIT does not find a name in level 1;
1354: - configure.in script is modified to add a new test (--enable-debug
1355: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1356: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1357: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1358: 'MATRIX' { 2 2 3 } GETR;
1359: - LOGSCALE intrinsic is improved and now, it can be used as
1360: { "main" "auxiliary" X Y } LOGSCALE;
1361: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1362: same than AXES:
1363: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1364: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1365: { { -10 10 } "automatic" } SCALE.
1366: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1367: because it changes only the dimension of the screen. To have a logarithmic
1368: scale, you must use LOGSCALE intrinsic:
1369: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1370: screen on second scale;
1371: - { X X } autoscale and { Y Y } logscale are now invalid;
1372: - *D is added (depth multiplication, for 3D graphics);
1373: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1374: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1375: - a major bug is fixed in GETI instrinsic when it is used with a name
1376: that contains a matrix or a vector (bad upper bounds conditions in
1377: incrementation);
1378: - DISP intrinsic now uses the 33-th flag. When it is not set
1379: (default), a final carriage return is sent to the terminal;
1380: - AXES intrinsic only takes a list that can contains the keywork
1381: "main" or "auxiliary". Before this modification, this keyword was in
1382: the first stack level;
1383: - vim syntax file is upgraded;
1384: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1385: option;
1386: - LAST is now disabled in the main loop of INT intrinsic;
1387: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1388: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1389: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1390: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1391: in 0);
1392: - LAST is disabled in the main loop of DRAW intrinsic;
1393: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1394: evaluation of an equation, the system stack is returned corrupted to the
1395: sequencer;
1396: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1397: of a loop are not integer or real.
1398: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1399: - the compilation stage aborts with an error message when two definitions
1400: have the same name. To improve the compilation() subroutine, I have to
1401: add some tests in gestion_variables.c;
1402: - recherche_type() subroutine ad some other connex subroutines are improved.
1403: Now, some syntax errors about object are caught and do not perform sequencer
1404: hangup;
1405: - readline is upgraded (minor compilation bug with recent gcc);
1406: - Makefile.am's and configure.in scripts are improved.
1407: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1408: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1409: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1410: the boxwidth, 1 by default);
1411: - recherche_type() is rewritten to be faster;
1412: - gsl is upgraded (release 1.3);
1413: - ncurses is upgraded and patched (release 5.3);
1414: - recherche_instruction_suivante() is fixed (string research with included
1415: '"') and rewritten to be faster;

1426: - a minor bug is fixed in evaluation subroutine;
1427: - vim syntax file is improved;
1428: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1429: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1430: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1431: is a quick and dirty workaround...);
1432: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1433: - rplconvert is improved.

1515: deleted too!;
1516: - configure script is improved (and it seems to be good ;-) );

1533: signal is an asynchonous "HALT" command;
1534: - SIGINT (CTRL+C) variables stack corruption is fixed;
1535: - IFERR seems to be fixed (in equation evaluation routine);

1543: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1544: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1545: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1546:
1547: Newton:[~/rpl/rpl] > time make install
1548: ...
1549: real 338m39.623s
1550: user 324m32.290s
