39: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
40: - major bug is fixed in STD format (1E7 sq prints 1);
41: - major bug is fixed in READ intrinsic (socket). This bug was introduced
42: by a new feature in glibc.
43: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
44: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
45: "ALL" IMPLICIT when it runs in interactive mode;
46: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
47: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
48: to use SAVE to manipulate global variables;
49: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
50: subroutines;
51: - fix major memory access violation in evaluation subroutine. Only occurs
52: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
53: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
54: when X was a vector or a table.
55: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)
56: - Gnuplot is upgraded;

83: - gnuplot is upgraded to 4.4.2 due to major bugs.
84: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
85: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
86: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
87: corruption. As internal memory management have been improved, a best fit
88: allocator like ptmalloc3 is not required anymore;
89: - gnuplot is upgraded to 4.4.1;
90: - deadlock is fixed in signal handlers: same mutex was used in standard
91: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
92: and signal handlers. A new signal handler specific mutex is added;
93: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
94: that has to be evaluated by ->NUM;
95: - rplfile build process is modify to be sure that rplfile is not modified
96: after rpl build stage (to be sure that rplfile checksum is not modified after

104: parent process was not interrupted if it is not group master process. To fix
105: this bug, SIGINJECT signal is not sent by child process but by control thread
106: in parent process;
107: - minor bug is fixed in data injection (POKE) that does not work as expected
108: when child process is protected by NRPROC.
109: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
110: - --enable-sysv-sems is added to configure script to use SystemV semaphores
111: functions instead of POSIX functions. This function is disabled or forced on
112: systems that does not provide correct POSIX or SysV semaphores subsystem;
113: - a dirty but not quick patch is written to workaround broken siginfo
114: structures. This patch has been successfully tested. It uses a segment of
115: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
116: (Unix PID);
117: - some OpenBSD's hacks are added;
118: - broken siginfo->si_pid field is now checked by configure script;
119: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

136: Level 0 and 1 variables adresses were swapped when a global variable masked
137: a name of RPL/2 routine;
138: - major bug is fixed in global variable creation subroutine. When a global
139: variable was created and when a local variable existed with the same name,
140: computed address of global variable was wrong;
141: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
142: is forced in front of all libraries.
143: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
144: - BACKTRACE intrinsic is added;
145: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
146: when this structure is included in IFERR/THEN/END structure and when an error is
147: caught;
148: - major bug is fixed in analyse() subroutine. When evaluation() returned error
149: in a compiled program, analyse() caught this error twice and randomly aborted
150: with a segmentation error;
151: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
152: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
153: signals;
154: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
155: matrix.

174: format in FCH (file descriptor) and SCK (socket descriptor);
175: - debug routines are improved;
176: - PROCID is added;
177: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
178: and to not use swap;
179: - major bug is fixed in sql support. SQL connections were closed in all chield
180: process;
181: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
182: discovered in Solaris thread safe allocators (libmalloc and libumem) that
183: are first fit class allocators. Solaris libmtmalloc works better and is
184: a best fit class allocator but its performance is poor than ptmalloc3
185: performance;
186: - major bug is fixed in ROW+ intrinsic (new row was not added where it
187: should);
188: - minor bugs are fixed in interruptions.c (semaphores values when error is
189: caught);
190: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
191: created by SPAWN;

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

260: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
261: each execution (md5 and sha1 sums) to enhance security. If one of these tools
262: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
263: on a non recoverable system error;
264: - openssl and sqlite3 libraries are added;
265: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
266: variable indicates RPL/2 root directory. If it is not set, root path
267: is given by configure script (d_exec_path);

301: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
302: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
303: signals sent to main process were not caught because DAEMON did not replace
304: old pid by new one;
305: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
306: evaluation when an error is reported from a subroutine in another subroutine.
307: For example, error was not caught in following program when it is executed with

330: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
331: - DISP now locks stdout;
332: - rpliconv is added to replace standard iconv provided by operating system.
333: Indeed, conversion between different encodages requires transliteration
334: that is not offered by some iconv utility;
335: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
336: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

338: - fprintf is replaced by some functions that allow transliterations between
339: locales;
340: - '"' can now be used in strings ("\"");
341: - iconv is called with -c in preprocessor stage. It is done to write
342: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;

355: - pipe() is overwritten by a macro to avoid a system error. Communication
356: between process are done with pipes and these pipes are managed by a
357: specific asynchrone thread. If a script try to create more threads than
358: management thread can destroy, you can quickly achieve maximum number of
359: opened files and pipe() shall return a system error. This macro tries to create
360: pipes. If pipe() function returns an error, macro waits and retries. If
361: number of retries is greater than a hardcoded value, macro returns an error;
362: - major bug (deadlock) is fixed in process and thread management. I hope
363: this bug shall be the last one;

373: was called before a pending interruption5 (SIGFSTOP), signal handler uses
374: a freed semaphore and corrupts heap;
375: - CLRERR is added to erase previous errors;
376: - ERRN and ERRM return exception message and number;
377: - major bug is fixed in interruptions.c. All signal are now bufferised
378: when semaphore_liste_threads is null to avoid deadlock. This bug only
379: occured when STOP was sent to a dying thread or process (when this thread or
380: process was running retrait_thread());
381: - matrix rank is computed before matrix inversion;
382: - file locks are added to stdin and stdout. stderr is not locked because
383: all messages written by signal handlers are sent to stderr;
384: - configure.in script is modified to test gcc version and avoid a bug in

402:
403: - SVL and SVD are added;
404: - COND and RANK are added;
405: - DIAG-> and ->DIAG are added;
406: - major bug is fixed in DET intrinsic. DET is rewritten to avoid usage of
407: eigenvalues. In a first time, matrix rank is estimated to force determinant
408: to zero if matrix is rank deficient. If not, a PLU decomposition is done to
409: compute determinant;
410: - QR matrix decomposition is added;
411: - LQ matrix decomposition is added;
412: - Fortran90 files are rewritten to use Fortran2003 bind(C) statement and
413: Fortran preprocessor;
414: - default compilation options are now -Wall -Wextra -Wno-pointer-sign
415: -Wno-unused-parameter;
416: - all mathematical exceptions are now signaled by exceptions instead of
417: execution error;
418: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
419: can call twice CSTOP without RSTOP;
420: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
421: SMPHRTRYDECR, SMPHGETV).
422: * Fri Jul 24 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.4 (RPL/2)
423: - semaphore is added in interruptions.c to avoid segmentation fault when STOP
424: signal is sent to a dying thread. Some mutexes are replaced by semaphores too
425: to be used in signal handlers;
426: - major bug (memory corruption) is fixed in COL- intrinsic;
427: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
428: software interrupt was caught;
429: - rplpp man page is added.
430: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
431: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
432: process termination);
433: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
434: its parent);
435: - a mutex to protect fork() syscall is added;
436: - all mutexes are unlocked after fork() in DETACH;
437: - minor bug (double free corruption) is fixed in CLOSE intrinsic;
438: - major bug is fixed in lecture_pipe when a nullified list is sent into a pipe;

441: there variables are not modifiable and only contains static user definitions;
442: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
443: - FORTRAN 77 file management subroutines are rewritten in pure C due to
444: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
445: in some cases (gcc/gfortran/libc/OS and arch conjonction);
446: - a memory leak is fixed in REMOVE intrinsic;
447: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
448: and due to a libmysqlclient that is not thread safe).
449: * Wen Jun 10 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.2 (RPL/2)
450: - new enhanced allocator is written for regular variables, static variables and
451: shared variables;

455: - --enable-profile flag is added to configure script. When this flag is
456: enabled, rpl is built with -pg option;
457: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
458: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
459: process is killed;
460: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
461: know typeof() intrinsic function. This function is not standard but exists
462: under Sun Studio, gcc, and maybe some others compilers. If this function does
463: not exist on your compiler, you can change its definition by old one in
464: src/rpl.h;
465: - fflush() can now be interrupted by signal (SunOS);
466: - fflush(NULL) is called before all fork() occurrences;
467: - generators returned by RDGN help are sorted;

485: is send from an external process;
486: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
487: deadlock when a huge amount of threads is launched);
488: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
489: arguments types are unsupported;
490: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
491: data are buffered. PLOT is used to draw these objects.);
492: - MARK instrinsic is added;

505: static variable that is shared by multiple threads;
506: - '->' intrinsic is improved. All object copies have been avoided;
507: - -n flag is added to catch HUP signal. stderr and stdout are redirected
508: to a file, stdin is redirected to /dev/null when control process is killed;
509: - a mutex is added to each object (before this modification,
510: RPL/2 used a global mutex and performances in multithreaded programs were very
511: poor.);
512: - ALARM is now interruptible;
513: - both PUT and PUTI intrinsics are improved and do not copy list and table
514: when nombre_occurrences == 1;

525: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
526: that all programs that worked with old SQL intrinsic can now work with
527: SQLQUERY. With all new programs, you can open a real connection to databases;
528: - NRPROC is added. This new intrinsic is used to catch error from child
529: process. Without NRPROC, any errors returned by child process cause
530: main process to abort;
531: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
532: starts a new process). There are no mutexes in RPL/2 because all spawned process
533: use specific context. Nevertheless, shared variables and associated mutexes
534: should be added;
535: - -D flag and DAEMONIZE intrinsic have been added;
536: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

673: before starting interrupt evaluation;
674: - -f parameter is added when iconv is called;
675: - as old file program was bugged, a new option is added to configure script.
676: When configure is called with --disable-encoding-autodetection, make does not
677: try to detect source encoding. Please, do not use if RPL/2 can be built
678: without this option !
679: - new garbage collector (and more efficient) is written;
680: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
681: not support real time signals, RPL/2 cannot use multitasking functions;
682: - error returned by preprocessor are now catched by RPL/2;
683: - -p option is added. With this option, all scripts are compiled before
684: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
685: 40% faster;
686: - read and write operations in pipe() are rewritten to be sure that such
687: operations are atomic;
688: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1210: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1211: on Debian distribution, but since cpp is in the default path, RPL/2 works
1212: fine...);
1213: - NOT is not correctly formatted in formateur.c:
1214: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1215: with a NOTZ function !
1216: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1217: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1219: - RPL/2 is tested with efence and valgrind;
1220: - configure.in script is modified;
1221: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1283: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1284: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1301: - SCLS is added;
1302: - DRWS now uses COLS to draw 2D graphics;
1303: - PPAR and SPAR are written. SPAR returns a list that contains the
1304: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1305: statistical variable, or "DISABLED" if its type is not one of the type of
1306: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1307: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1308: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1309: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1310: disabled. Arguments of EXTERNAL are case sensitive because the external
1311: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1312: of known external functions but add the new list to the last. { "all" }
1313: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1314: external names of the known functions;
1315: - mkrplso.in is modified.
1316: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1317: - vim syntax file is upgraded;
1318: - a minor mistake is fixed in recherche_instruction_suivante();
1319: - some minor memory leaks are fixed in recherche_type() function. They only

1328: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1329: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1330: VISIT does not find a name in level 1;
1331: - configure.in script is modified to add a new test (--enable-debug
1332: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1333: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1334: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1335: 'MATRIX' { 2 2 3 } GETR;
1336: - LOGSCALE intrinsic is improved and now, it can be used as
1337: { "main" "auxiliary" X Y } LOGSCALE;
1338: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1339: same than AXES:
1340: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1341: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1342: { { -10 10 } "automatic" } SCALE.
1343: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1344: because it changes only the dimension of the screen. To have a logarithmic
1345: scale, you must use LOGSCALE intrinsic:
1346: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1347: screen on second scale;
1348: - { X X } autoscale and { Y Y } logscale are now invalid;
1349: - *D is added (depth multiplication, for 3D graphics);
1350: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1351: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1352: - a major bug is fixed in GETI instrinsic when it is used with a name
1353: that contains a matrix or a vector (bad upper bounds conditions in
1354: incrementation);
1355: - DISP intrinsic now uses the 33-th flag. When it is not set
1356: (default), a final carriage return is sent to the terminal;
1357: - AXES intrinsic only takes a list that can contains the keywork
1358: "main" or "auxiliary". Before this modification, this keyword was in
1359: the first stack level;
1360: - vim syntax file is upgraded;
1361: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1362: option;
1363: - LAST is now disabled in the main loop of INT intrinsic;
1364: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1365: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1366: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1367: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1368: in 0);
1369: - LAST is disabled in the main loop of DRAW intrinsic;
1370: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1371: evaluation of an equation, the system stack is returned corrupted to the
1372: sequencer;
1373: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1374: of a loop are not integer or real.
1375: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1376: - the compilation stage aborts with an error message when two definitions
1377: have the same name. To improve the compilation() subroutine, I have to
1378: add some tests in gestion_variables.c;
1379: - recherche_type() subroutine ad some other connex subroutines are improved.
1380: Now, some syntax errors about object are caught and do not perform sequencer
1381: hangup;
1382: - readline is upgraded (minor compilation bug with recent gcc);
1383: - Makefile.am's and configure.in scripts are improved.
1384: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1385: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1386: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1387: the boxwidth, 1 by default);
1388: - recherche_type() is rewritten to be faster;
1389: - gsl is upgraded (release 1.3);
1390: - ncurses is upgraded and patched (release 5.3);
1391: - recherche_instruction_suivante() is fixed (string research with included
1392: '"') and rewritten to be faster;

1404: - vim syntax file is improved;
1405: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1406: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1407: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1408: is a quick and dirty workaround...);
1409: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1410: - rplconvert is improved.
