96: by a new feature in glibc.
97: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
98: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
99: "ALL" IMPLICIT when it runs in interactive mode;
100: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
101: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
102: to use SAVE to manipulate global variables;
103: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
104: subroutines;
105: - fix major memory access violation in evaluation subroutine. Only occurs
106: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
107: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
108: when X was a vector or a table.

138: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
139: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
140: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
141: corruption. As internal memory management have been improved, a best fit
142: allocator like ptmalloc3 is not required anymore;
143: - gnuplot is upgraded to 4.4.1;
144: - deadlock is fixed in signal handlers: same mutex was used in standard
145: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
146: and signal handlers. A new signal handler specific mutex is added;
147: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
148: that has to be evaluated by ->NUM;
149: - rplfile build process is modify to be sure that rplfile is not modified
150: after rpl build stage (to be sure that rplfile checksum is not modified after

158: parent process was not interrupted if it is not group master process. To fix
159: this bug, SIGINJECT signal is not sent by child process but by control thread
160: in parent process;
161: - minor bug is fixed in data injection (POKE) that does not work as expected
162: when child process is protected by NRPROC.
163: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
164: - --enable-sysv-sems is added to configure script to use SystemV semaphores
165: functions instead of POSIX functions. This function is disabled or forced on
166: systems that does not provide correct POSIX or SysV semaphores subsystem;
167: - a dirty but not quick patch is written to workaround broken siginfo
168: structures. This patch has been successfully tested. It uses a segment of
169: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
170: (Unix PID);
171: - some OpenBSD's hacks are added;
172: - broken siginfo->si_pid field is now checked by configure script;
173: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

190: Level 0 and 1 variables adresses were swapped when a global variable masked
191: a name of RPL/2 routine;
192: - major bug is fixed in global variable creation subroutine. When a global
193: variable was created and when a local variable existed with the same name,
194: computed address of global variable was wrong;
195: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
196: is forced in front of all libraries.

198: - BACKTRACE intrinsic is added;
199: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
200: when this structure is included in IFERR/THEN/END structure and when an error is
201: caught;
202: - major bug is fixed in analyse() subroutine. When evaluation() returned error
203: in a compiled program, analyse() caught this error twice and randomly aborted
204: with a segmentation error;
205: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
206: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
207: signals;
208: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
209: matrix.

228: format in FCH (file descriptor) and SCK (socket descriptor);
229: - debug routines are improved;
230: - PROCID is added;
231: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
232: and to not use swap;
233: - major bug is fixed in sql support. SQL connections were closed in all chield
234: process;
235: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
236: discovered in Solaris thread safe allocators (libmalloc and libumem) that
237: are first fit class allocators. Solaris libmtmalloc works better and is
238: a best fit class allocator but its performance is poor than ptmalloc3
239: performance;
240: - major bug is fixed in ROW+ intrinsic (new row was not added where it
241: should);
242: - minor bugs are fixed in interruptions.c (semaphores values when error is
243: caught);
244: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
245: created by SPAWN;

255: information about shared variable was not copied to new processus structure;
256: - some little memory leaks are fixed in evaluation(), recherche_type() and
257: sequenceur(). They only occured when syntax error were caught;
258: - IMPLICIT causes execution error instead system error;
259: - Hurd support is improved but currently broken because Hurd does not support
260: SIG_INFO. Work in progress;
261: - OpenBSD specific support is removed from sources;
262: - support for Mac OS X and Windows/Cygwin is added.

314: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
315: each execution (md5 and sha1 sums) to enhance security. If one of these tools
316: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
317: on a non recoverable system error;
318: - openssl and sqlite3 libraries are added;
319: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

357: signals sent to main process were not caught because DAEMON did not replace
358: old pid by new one;
359: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
360: evaluation when an error is reported from a subroutine in another subroutine.
361: For example, error was not caught in following program when it is executed with

384: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
385: - DISP now locks stdout;
386: - rpliconv is added to replace standard iconv provided by operating system.
387: Indeed, conversion between different encodages requires transliteration
388: that is not offered by some iconv utility;
389: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
390: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
391: not be found), SYSEVAL enters in a dead lock;
392: - fprintf is replaced by some functions that allow transliterations between
393: locales;
394: - '"' can now be used in strings ("\"");
395: - iconv is called with -c in preprocessor stage. It is done to write
396: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
397: - double free is fixed in liberation() (type SQL, only occurs when locale is
398: set);
399: - LOCALIZATION, UCASE and LCASE are added;
400: - major bug is fixed in EXIT intrinsic that was able to return a false
401: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
402: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
403: used in onLoading from shared library, USE was pushed on stack as algebraic
404: expression;
405: - libiconv is upgraded to 1.13.1;
406: - gnuplot is upgraded to 4.2.6;
407: - gsl is upgraded to 1.13.
408: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
409: - pipe() is overwritten by a macro to avoid a system error. Communication
410: between process are done with pipes and these pipes are managed by a
411: specific asynchrone thread. If a script try to create more threads than
412: management thread can destroy, you can quickly achieve maximum number of
413: opened files and pipe() shall return a system error. This macro tries to create
414: pipes. If pipe() function returns an error, macro waits and retries. If
415: number of retries is greater than a hardcoded value, macro returns an error;
416: - major bug (deadlock) is fixed in process and thread management. I hope
417: this bug shall be the last one;
418: - major bug is fixed in DET intrinsic (determinant was computed without LU
419: diagonalization);
420: - SWAPCNTXT is added;
421: - minor bug is fixed in Makefile.am (licences rule).
422: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
423: - some bugfixes are added in process management;
424: - all process management is rewritten to avoid usage of defunct process
425: or thread number;
426: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
427: was called before a pending interruption5 (SIGFSTOP), signal handler uses
428: a freed semaphore and corrupts heap;
429: - CLRERR is added to erase previous errors;
430: - ERRN and ERRM return exception message and number;
431: - major bug is fixed in interruptions.c. All signal are now bufferised
432: when semaphore_liste_threads is null to avoid deadlock. This bug only
433: occured when STOP was sent to a dying thread or process (when this thread or
434: process was running retrait_thread());
435: - matrix rank is computed before matrix inversion;
436: - file locks are added to stdin and stdout. stderr is not locked because
437: all messages written by signal handlers are sent to stderr;
438: - configure.in script is modified to test gcc version and avoid a bug in
439: gcc older than 4.4;
440: - some benchmarks have been done :

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

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

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

579: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
580: that all programs that worked with old SQL intrinsic can now work with
581: SQLQUERY. With all new programs, you can open a real connection to databases;
582: - NRPROC is added. This new intrinsic is used to catch error from child
583: process. Without NRPROC, any errors returned by child process cause
584: main process to abort;
585: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
586: starts a new process). There are no mutexes in RPL/2 because all spawned process
587: use specific context. Nevertheless, shared variables and associated mutexes
588: should be added;

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

659: nullified lists;
660: - rplexternals.h is modified and improved;
661: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and

675: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
676: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
677: workaround for this major bug. Nevertheless, all others capabilities seems to
678: work fine;
679: - '->' is modified to return error when program tries to initialiaze two

727: before starting interrupt evaluation;
728: - -f parameter is added when iconv is called;
729: - as old file program was bugged, a new option is added to configure script.
730: When configure is called with --disable-encoding-autodetection, make does not
731: try to detect source encoding. Please, do not use if RPL/2 can be built
732: without this option !
733: - new garbage collector (and more efficient) is written;
734: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
735: not support real time signals, RPL/2 cannot use multitasking functions;
736: - error returned by preprocessor are now catched by RPL/2;
737: - -p option is added. With this option, all scripts are compiled before
738: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
739: 40% faster;
740: - read and write operations in pipe() are rewritten to be sure that such
741: operations are atomic;

883: - external wrapper (rplplot) is written to force usage of gnuplot provided
884: by RPL/2 if it is built during build process. If this build does not exist,
885: it tries to launch regular gnuplot;
886: - gnuplot is added to source tree to avoid some trouble between preinstalled
887: gnuplot and release used by RPL/2. This addition to source tree is
888: required by some incompatibility between gnuplot releases;
889: - Lapack is upgraded to 3.1.1 release;
890: - GSL is upgraded to 1.9 revision;

936: With STATIC, next variables created by '->' are static;
937: - PROTECT and UNPROTECT are added to protect variables against write
938: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
939: versions of PROTECT and UNPROTECT that only deal with global variables
940: (see RCL/SAVE);
941: - variable management routines have been rewritten. The new ones are
942: uncompatible with the old ones. Before these changes, a local variable
943: was exported to a child subroutine, but cannot be modified into this
944: child subroutine. Now, a local variable is accessible only in its subroutine;
945: - SAVE intrinsic is added to manipulate global variables;

1266: fine...);
1267: - NOT is not correctly formatted in formateur.c:
1268: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1269: with a NOTZ function !
1270: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1273: - RPL/2 is tested with efence and valgrind;
1274: - configure.in script is modified;
1275: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1336: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1337: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1338: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1355: - SCLS is added;
1356: - DRWS now uses COLS to draw 2D graphics;
1357: - PPAR and SPAR are written. SPAR returns a list that contains the
1358: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1359: statistical variable, or "DISABLED" if its type is not one of the type of
1360: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1361: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1362: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1363: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1364: disabled. Arguments of EXTERNAL are case sensitive because the external
1365: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1366: of known external functions but add the new list to the last. { "all" }
1367: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1368: external names of the known functions;
1369: - mkrplso.in is modified.
1370: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1384: VISIT does not find a name in level 1;
1385: - configure.in script is modified to add a new test (--enable-debug
1386: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1387: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1388: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1389: 'MATRIX' { 2 2 3 } GETR;
1390: - LOGSCALE intrinsic is improved and now, it can be used as
1391: { "main" "auxiliary" X Y } LOGSCALE;
1392: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1393: same than AXES:
1394: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1395: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1396: { { -10 10 } "automatic" } SCALE.
1397: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1398: because it changes only the dimension of the screen. To have a logarithmic
1399: scale, you must use LOGSCALE intrinsic:
1400: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1401: screen on second scale;
1402: - { X X } autoscale and { Y Y } logscale are now invalid;
1403: - *D is added (depth multiplication, for 3D graphics);
1404: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1405: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1406: - a major bug is fixed in GETI instrinsic when it is used with a name
1407: that contains a matrix or a vector (bad upper bounds conditions in
1408: incrementation);
1409: - DISP intrinsic now uses the 33-th flag. When it is not set
1410: (default), a final carriage return is sent to the terminal;
1411: - AXES intrinsic only takes a list that can contains the keywork
1412: "main" or "auxiliary". Before this modification, this keyword was in
1413: the first stack level;
1414: - vim syntax file is upgraded;
1415: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1416: option;
1417: - LAST is now disabled in the main loop of INT intrinsic;
1418: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1419: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1420: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1421: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1422: in 0);
1423: - LAST is disabled in the main loop of DRAW intrinsic;
1424: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1425: evaluation of an equation, the system stack is returned corrupted to the
1426: sequencer;
1427: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1428: of a loop are not integer or real.
1429: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1432: add some tests in gestion_variables.c;
1433: - recherche_type() subroutine ad some other connex subroutines are improved.
1434: Now, some syntax errors about object are caught and do not perform sequencer
1435: hangup;
1436: - readline is upgraded (minor compilation bug with recent gcc);
1437: - Makefile.am's and configure.in scripts are improved.
1438: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1439: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1440: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1442: - recherche_type() is rewritten to be faster;
1443: - gsl is upgraded (release 1.3);
1444: - ncurses is upgraded and patched (release 5.3);
1445: - recherche_instruction_suivante() is fixed (string research with included
1446: '"') and rewritten to be faster;

1457: - a minor bug is fixed in evaluation subroutine;
1458: - vim syntax file is improved;
1459: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1460: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1461: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1462: is a quick and dirty workaround...);
1463: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1464: - rplconvert is improved.

1546: deleted too!;
1547: - configure script is improved (and it seems to be good ;-) );

1563: that the RPL/2 seqencer must stop and must give a prompt. This
1564: signal is an asynchonous "HALT" command;
1565: - SIGINT (CTRL+C) variables stack corruption is fixed;
1566: - IFERR seems to be fixed (in equation evaluation routine);
1567: - Memory leak is fixed (ADR object type);

1574: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1575: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1576: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1577:
1578: Newton:[~/rpl/rpl] > time make install
1579: ...
1580: real 338m39.623s
1581: user 324m32.290s
1582: sys 10m47.380s
1583: Newton:[~/rpl/rpl] >

1585: I don't know if you will compile this language on old worstations, but
1586: it is usable ;-) ;
1587: - SYSEVAL is improved. An external program can be called without any shell.
