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

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

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

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

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

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

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

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

334: - DISP now locks stdout;
335: - rpliconv is added to replace standard iconv provided by operating system.
336: Indeed, conversion between different encodages requires transliteration
337: that is not offered by some iconv utility;
338: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
339: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

347: set);
348: - LOCALIZATION, UCASE and LCASE are added;

358: - pipe() is overwritten by a macro to avoid a system error. Communication
359: between process are done with pipes and these pipes are managed by a
360: specific asynchrone thread. If a script try to create more threads than
361: management thread can destroy, you can quickly achieve maximum number of
362: opened files and pipe() shall return a system error. This macro tries to create
363: pipes. If pipe() function returns an error, macro waits and retries. If
364: number of retries is greater than a hardcoded value, macro returns an error;
365: - major bug (deadlock) is fixed in process and thread management. I hope
366: this bug shall be the last one;
367: - major bug is fixed in DET intrinsic (determinant was computed without LU
368: diagonalization);

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

406: - SVL and SVD are added;
407: - COND and RANK are added;
408: - DIAG-> and ->DIAG are added;
409: - major bug is fixed in DET intrinsic. DET is rewritten to avoid usage of

412: compute determinant;
413: - QR matrix decomposition is added;
414: - LQ matrix decomposition is added;
415: - Fortran90 files are rewritten to use Fortran2003 bind(C) statement and

418: -Wno-unused-parameter;
419: - all mathematical exceptions are now signaled by exceptions instead of
420: execution error;
421: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
422: can call twice CSTOP without RSTOP;
423: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
424: SMPHRTRYDECR, SMPHGETV).

428: to be used in signal handlers;
429: - major bug (memory corruption) is fixed in COL- intrinsic;
430: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
431: software interrupt was caught;
432: - rplpp man page is added.
433: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
434: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
435: process termination);
436: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
437: its parent);
438: - a mutex to protect fork() syscall is added;

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

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

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

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

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

1213: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1214: on Debian distribution, but since cpp is in the default path, RPL/2 works
1215: fine...);
1216: - NOT is not correctly formatted in formateur.c:
1217: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1218: with a NOTZ function !
1219: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1220: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1222: - RPL/2 is tested with efence and valgrind;
1223: - configure.in script is modified;
1224: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1285: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1286: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1287: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1304: - SCLS is added;
1305: - DRWS now uses COLS to draw 2D graphics;
1306: - PPAR and SPAR are written. SPAR returns a list that contains the
1307: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1308: statistical variable, or "DISABLED" if its type is not one of the type of
1309: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1310: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1311: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1312: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1313: disabled. Arguments of EXTERNAL are case sensitive because the external
1314: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1315: of known external functions but add the new list to the last. { "all" }
1316: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1317: external names of the known functions;
1318: - mkrplso.in is modified.
1319: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1320: - vim syntax file is upgraded;
1321: - a minor mistake is fixed in recherche_instruction_suivante();
1322: - some minor memory leaks are fixed in recherche_type() function. They only

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

1381: add some tests in gestion_variables.c;
1382: - recherche_type() subroutine ad some other connex subroutines are improved.
1383: Now, some syntax errors about object are caught and do not perform sequencer
1384: hangup;

1386: - Makefile.am's and configure.in scripts are improved.
1387: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1388: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1389: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1390: the boxwidth, 1 by default);
1391: - recherche_type() is rewritten to be faster;
1392: - gsl is upgraded (release 1.3);
1393: - ncurses is upgraded and patched (release 5.3);
1394: - recherche_instruction_suivante() is fixed (string research with included
1395: '"') and rewritten to be faster;

1409: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1410: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1411: is a quick and dirty workaround...);
1412: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1413: - rplconvert is improved.

1498: if you compile a beta release, you can compile a stable RPL/2;
1499: - new syntax and ftplugin written for vim 6.0.

1511: - SIGTSTP (CTRL+Z) is added. In a script, a SIGTSTP signal signifies
1512: that the RPL/2 seqencer must stop and must give a prompt. This
1513: signal is an asynchonous "HALT" command;
1514: - SIGINT (CTRL+C) variables stack corruption is fixed;

1522: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1523: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1524: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1525: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1526:
1527: Newton:[~/rpl/rpl] > time make install
1528: ...
1529: real 338m39.623s
1530: user 324m32.290s
1531: sys 10m47.380s
1532: Newton:[~/rpl/rpl] >
1533:
1534: I don't know if you will compile this language on old worstations, but
1535: it is usable ;-) ;
1536: - SYSEVAL is improved. An external program can be called without any shell.
1537: Thus, even if the sticky bit is set, RPL/2 can not give a shell root when
1538: a SYSEVAL command crashes;
