67: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
68: - major bug is fixed in STD format (1E7 sq prints 1);
69: - major bug is fixed in READ intrinsic (socket). This bug was introduced
70: by a new feature in glibc.
71: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
72: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
73: "ALL" IMPLICIT when it runs in interactive mode;
74: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
75: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
76: to use SAVE to manipulate global variables;
77: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
78: subroutines;
79: - fix major memory access violation in evaluation subroutine. Only occurs
80: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
81: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
82: when X was a vector or a table.
83: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

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

132: parent process was not interrupted if it is not group master process. To fix
133: this bug, SIGINJECT signal is not sent by child process but by control thread
134: in parent process;
135: - minor bug is fixed in data injection (POKE) that does not work as expected
136: when child process is protected by NRPROC.
137: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
138: - --enable-sysv-sems is added to configure script to use SystemV semaphores
139: functions instead of POSIX functions. This function is disabled or forced on
140: systems that does not provide correct POSIX or SysV semaphores subsystem;
141: - a dirty but not quick patch is written to workaround broken siginfo
142: structures. This patch has been successfully tested. It uses a segment of
143: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
144: (Unix PID);
145: - some OpenBSD's hacks are added;
146: - broken siginfo->si_pid field is now checked by configure script;

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

172: - BACKTRACE intrinsic is added;
173: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
174: when this structure is included in IFERR/THEN/END structure and when an error is
175: caught;
176: - major bug is fixed in analyse() subroutine. When evaluation() returned error
177: in a compiled program, analyse() caught this error twice and randomly aborted
178: with a segmentation error;
179: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
180: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
181: signals;

205: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
206: and to not use swap;
207: - major bug is fixed in sql support. SQL connections were closed in all chield
208: process;
209: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
210: discovered in Solaris thread safe allocators (libmalloc and libumem) that
211: are first fit class allocators. Solaris libmtmalloc works better and is
212: a best fit class allocator but its performance is poor than ptmalloc3
213: performance;
214: - major bug is fixed in ROW+ intrinsic (new row was not added where it
215: should);
216: - minor bugs are fixed in interruptions.c (semaphores values when error is
217: caught);
218: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process

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

289: each execution (md5 and sha1 sums) to enhance security. If one of these tools
290: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
291: on a non recoverable system error;
292: - openssl and sqlite3 libraries are added;
293: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

388: pipes. If pipe() function returns an error, macro waits and retries. If
389: number of retries is greater than a hardcoded value, macro returns an error;
390: - major bug (deadlock) is fixed in process and thread management. I hope
391: this bug shall be the last one;
392: - major bug is fixed in DET intrinsic (determinant was computed without LU
393: diagonalization);
394: - SWAPCNTXT is added;
395: - minor bug is fixed in Makefile.am (licences rule).
396: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
397: - some bugfixes are added in process management;
398: - all process management is rewritten to avoid usage of defunct process
399: or thread number;
400: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
401: was called before a pending interruption5 (SIGFSTOP), signal handler uses
402: a freed semaphore and corrupts heap;
403: - CLRERR is added to erase previous errors;
404: - ERRN and ERRM return exception message and number;
405: - major bug is fixed in interruptions.c. All signal are now bufferised
406: when semaphore_liste_threads is null to avoid deadlock. This bug only
407: occured when STOP was sent to a dying thread or process (when this thread or
408: process was running retrait_thread());
409: - matrix rank is computed before matrix inversion;
410: - file locks are added to stdin and stdout. stderr is not locked because
411: all messages written by signal handlers are sent to stderr;
412: - configure.in script is modified to test gcc version and avoid a bug in
413: gcc older than 4.4;
414: - some benchmarks have been done :

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

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

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

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

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

711: - -p option is added. With this option, all scripts are compiled before
712: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
713: 40% faster;
714: - read and write operations in pipe() are rewritten to be sure that such
715: operations are atomic;

857: - external wrapper (rplplot) is written to force usage of gnuplot provided
858: by RPL/2 if it is built during build process. If this build does not exist,
859: it tries to launch regular gnuplot;
860: - gnuplot is added to source tree to avoid some trouble between preinstalled
861: gnuplot and release used by RPL/2. This addition to source tree is

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

1240: fine...);
1241: - NOT is not correctly formatted in formateur.c:
1242: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1243: with a NOTZ function !
1244: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1247: - RPL/2 is tested with efence and valgrind;
1248: - configure.in script is modified;
1249: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1310: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1311: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1312: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1329: - SCLS is added;
1330: - DRWS now uses COLS to draw 2D graphics;
1331: - PPAR and SPAR are written. SPAR returns a list that contains the
1332: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1333: statistical variable, or "DISABLED" if its type is not one of the type of
1334: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1335: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1336: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1337: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1338: disabled. Arguments of EXTERNAL are case sensitive because the external
1339: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1340: of known external functions but add the new list to the last. { "all" }
1341: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1342: external names of the known functions;
1343: - mkrplso.in is modified.
1344: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1345: - vim syntax file is upgraded;
1346: - a minor mistake is fixed in recherche_instruction_suivante();

1357: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1358: VISIT does not find a name in level 1;
1359: - configure.in script is modified to add a new test (--enable-debug
1360: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1361: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1362: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1363: 'MATRIX' { 2 2 3 } GETR;
1364: - LOGSCALE intrinsic is improved and now, it can be used as
1365: { "main" "auxiliary" X Y } LOGSCALE;
1366: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1367: same than AXES:
1368: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1369: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1370: { { -10 10 } "automatic" } SCALE.
1371: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1372: because it changes only the dimension of the screen. To have a logarithmic
1373: scale, you must use LOGSCALE intrinsic:
1374: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1375: screen on second scale;
1376: - { X X } autoscale and { Y Y } logscale are now invalid;
1377: - *D is added (depth multiplication, for 3D graphics);
1378: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1379: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1380: - a major bug is fixed in GETI instrinsic when it is used with a name
1381: that contains a matrix or a vector (bad upper bounds conditions in
1382: incrementation);
1383: - DISP intrinsic now uses the 33-th flag. When it is not set
1384: (default), a final carriage return is sent to the terminal;
1385: - AXES intrinsic only takes a list that can contains the keywork
1386: "main" or "auxiliary". Before this modification, this keyword was in
1387: the first stack level;
1388: - vim syntax file is upgraded;
1389: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1390: option;
1391: - LAST is now disabled in the main loop of INT intrinsic;
1392: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1393: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1394: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1395: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1396: in 0);
1397: - LAST is disabled in the main loop of DRAW intrinsic;
1398: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1399: evaluation of an equation, the system stack is returned corrupted to the
1400: sequencer;
1401: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1402: of a loop are not integer or real.
1403: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1404: - the compilation stage aborts with an error message when two definitions
1405: have the same name. To improve the compilation() subroutine, I have to
1406: add some tests in gestion_variables.c;
1407: - recherche_type() subroutine ad some other connex subroutines are improved.
1408: Now, some syntax errors about object are caught and do not perform sequencer
1409: hangup;
1410: - readline is upgraded (minor compilation bug with recent gcc);
1411: - Makefile.am's and configure.in scripts are improved.
1412: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1413: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1414: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1415: the boxwidth, 1 by default);
1416: - recherche_type() is rewritten to be faster;
1417: - gsl is upgraded (release 1.3);
1418: - ncurses is upgraded and patched (release 5.3);
1419: - recherche_instruction_suivante() is fixed (string research with included
1420: '"') and rewritten to be faster;

1434: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1435: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1436: is a quick and dirty workaround...);
1437: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1438: - rplconvert is improved.

1520: deleted too!;
1521: - configure script is improved (and it seems to be good ;-) );

1538: signal is an asynchonous "HALT" command;
1539: - SIGINT (CTRL+C) variables stack corruption is fixed;
1540: - IFERR seems to be fixed (in equation evaluation routine);

1549: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1550: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1551:
1552: Newton:[~/rpl/rpl] > time make install
1553: ...
1554: real 338m39.623s
1555: user 324m32.290s
