Annotation of rpl/ChangeLog, revision 1.167
1.154 bertrand 1: * Tue Dec 18 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.13 (RPL/2)
1.167 ! bertrand 2: - ATEXIT registered procedure is now executed even if program is stopped by
! 3: SIGINT;
1.165 bertrand 4: - minor bug is fixed in TOKENIZE intrinsic instruction. TOKENIZE did not work on
5: a copy of input string;
1.164 bertrand 6: - major bug (segfault) is fixed in liste_variables(). It only occurs
7: when this function is called with shared variables;
1.163 bertrand 8: - all internal data are now stored in 64 bits wide integers (even is 32 bits
9: ABI is selected);
1.162 bertrand 10: - major bug is fixed in recherche_instruction_suivante(). In some
11: circumstances, this function can return a spurious error;
1.161 bertrand 12: - new NATIVE*(*) data format is added. By default, native*(*) is used
13: to write data without precision loss. It can also be used to write
14: complex objects like expressions, lists or tables;
1.160 bertrand 15: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
16: internal value was good but RPL/2 was not able to correctly display
17: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented
18: in integer. All abs(), fabs() and labs() present in source code have ben checked
19: to avoid this kind of bug;

1.155 bertrand 25: - transliteration is avoid in rpl-core file generation to authorize core
26: creation even if a transliteration error is caught;
27: - major bug is fixed in evaluation(). System stack was not correctly
28: destacked when execution error occurs;
1.154 bertrand 29: - major bug is fixed in READ (socket interface);
30: - minor bug is fixed in analyse_flux().

54: calling thread;
1.144 bertrand 55: - static variables are now written in a variables tree;
1.136 bertrand 56: - major bug is fixed in STO intrinsic. STO returns an error when it has

228: - major bug is fixed in STD format (1E7 sq prints 1);
229: - major bug is fixed in READ intrinsic (socket). This bug was introduced
230: by a new feature in glibc.
231: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
232: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
233: "ALL" IMPLICIT when it runs in interactive mode;
234: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
235: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
236: to use SAVE to manipulate global variables;
237: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
238: subroutines;
239: - fix major memory access violation in evaluation subroutine. Only occurs
240: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
241: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
242: when X was a vector or a table.

273: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
274: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
275: corruption. As internal memory management have been improved, a best fit
276: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 277: - gnuplot is upgraded to 4.4.1;
278: - deadlock is fixed in signal handlers: same mutex was used in standard
279: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
280: and signal handlers. A new signal handler specific mutex is added;
281: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
282: that has to be evaluated by ->NUM;
1.49 bertrand 283: - rplfile build process is modify to be sure that rplfile is not modified
284: after rpl build stage (to be sure that rplfile checksum is not modified after

289: ABORT now works on eComStation;
290: - sqlite is upgraded to 3.7.2;
291: - bug is fixed in software interrupts. When both process have different PID,
292: parent process was not interrupted if it is not group master process. To fix
293: this bug, SIGINJECT signal is not sent by child process but by control thread
294: in parent process;
1.46 bertrand 295: - minor bug is fixed in data injection (POKE) that does not work as expected
296: when child process is protected by NRPROC.
1.44 bertrand 297: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 298: - --enable-sysv-sems is added to configure script to use SystemV semaphores
299: functions instead of POSIX functions. This function is disabled or forced on
300: systems that does not provide correct POSIX or SysV semaphores subsystem;
301: - a dirty but not quick patch is written to workaround broken siginfo
302: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 303: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 304: (Unix PID);
1.41 bertrand 305: - some OpenBSD's hacks are added;
306: - broken siginfo->si_pid field is now checked by configure script;

1.39 bertrand 310: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 311: or freeaddrinfo;
1.39 bertrand 312: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
313: - major bug is fixed in CHR intrinsic when obtained character is not printable;
314: - Lapack is upgraded to 3.2.2;
1.37 bertrand 315: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
1.36 bertrand 316: - TOKENIZE is now able to convert escape sequences;
317: - ATPOKE and CLRATPOKE new intrinsics are added;
318: - --enable-full-static configure flag is added. With this flag, mysql and
319: postgresql libraries are statically linked in rpl executable;
320: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 321: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 322: - units is upgraded to 1.88;
323: - another major bug is fixed in the same variable creation subroutine.
324: Level 0 and 1 variables adresses were swapped when a global variable masked
325: a name of RPL/2 routine;
1.35 bertrand 326: - major bug is fixed in global variable creation subroutine. When a global
327: variable was created and when a local variable existed with the same name,
328: computed address of global variable was wrong;
329: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3

332: - BACKTRACE intrinsic is added;
333: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
334: when this structure is included in IFERR/THEN/END structure and when an error is
335: caught;
336: - major bug is fixed in analyse() subroutine. When evaluation() returned error
337: in a compiled program, analyse() caught this error twice and randomly aborted
338: with a segmentation error;
339: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
340: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
341: signals;
342: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
343: matrix.

368: process;
369: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
370: discovered in Solaris thread safe allocators (libmalloc and libumem) that

375: should);
376: - minor bugs are fixed in interruptions.c (semaphores values when error is
377: caught);
378: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
379: created by SPAWN;
380: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
381: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 382: - ONEXIT is renamed in ATEXIT;
383: - ONEXIT new intrinsic is added.

389: information about shared variable was not copied to new processus structure;
1.19 bertrand 390: - some little memory leaks are fixed in evaluation(), recherche_type() and
391: sequenceur(). They only occured when syntax error were caught;
392: - IMPLICIT causes execution error instead system error;

394: SIG_INFO. Work in progress;
395: - OpenBSD specific support is removed from sources;
396: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 397: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

1.13 bertrand 436: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
437: - in formatted file, string format returned a variable length string even if
438: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 439: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 440: - keyed access files support is added. Currently, only formatted files are

451: on a non recoverable system error;
452: - openssl and sqlite3 libraries are added;
453: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
454: variable indicates RPL/2 root directory. If it is not set, root path
455: is given by configure script (d_exec_path);
1.11 bertrand 456: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

490: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
491: signals sent to main process were not caught because DAEMON did not replace
492: old pid by new one;
493: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
494: evaluation when an error is reported from a subroutine in another subroutine.
495: For example, error was not caught in following program when it is executed with
496: -p option :

502: script file contains a multibyte character;
503: - IN intrinsic is added;
504: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
505: returned false ;
506: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
507: programs;
508: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
509: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

526: - fprintf is replaced by some functions that allow transliterations between
527: locales;
528: - '"' can now be used in strings ("\"");
529: - iconv is called with -c in preprocessor stage. It is done to write

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

561: was called before a pending interruption5 (SIGFSTOP), signal handler uses
562: a freed semaphore and corrupts heap;
563: - CLRERR is added to erase previous errors;
564: - ERRN and ERRM return exception message and number;
565: - major bug is fixed in interruptions.c. All signal are now bufferised
566: when semaphore_liste_threads is null to avoid deadlock. This bug only
567: occured when STOP was sent to a dying thread or process (when this thread or
568: process was running retrait_thread());
569: - matrix rank is computed before matrix inversion;
570: - file locks are added to stdin and stdout. stderr is not locked because

714: that all programs that worked with old SQL intrinsic can now work with
715: SQLQUERY. With all new programs, you can open a real connection to databases;
716: - NRPROC is added. This new intrinsic is used to catch error from child
717: process. Without NRPROC, any errors returned by child process cause
718: main process to abort;
719: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
720: starts a new process). There are no mutexes in RPL/2 because all spawned process
721: use specific context. Nevertheless, shared variables and associated mutexes
722: should be added;

734: - NEWPLANE is added;
735: - LINE is added;
736: - DGTIZ is added;
737: - major bug is fixed in ROW-> intrinsic (comes from new garbage collector);

739: it's done. Data integrity is now respected during transmission (POKE, SEND and
740: SWI);
741: - ITRACE is added. This intrinsic is only used to debug internal structures and
742: should not be used in regular programs;
743: - SWISTATUS is written;

863: - as old file program was bugged, a new option is added to configure script.
864: When configure is called with --disable-encoding-autodetection, make does not
865: try to detect source encoding. Please, do not use if RPL/2 can be built
866: without this option !
867: - new garbage collector (and more efficient) is written;
868: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
869: not support real time signals, RPL/2 cannot use multitasking functions;

871: - -p option is added. With this option, all scripts are compiled before
872: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
873: 40% faster;
874: - read and write operations in pipe() are rewritten to be sure that such
875: operations are atomic;
876: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1017: - external wrapper (rplplot) is written to force usage of gnuplot provided
1018: by RPL/2 if it is built during build process. If this build does not exist,
1019: it tries to launch regular gnuplot;
1020: - gnuplot is added to source tree to avoid some trouble between preinstalled
1021: gnuplot and release used by RPL/2. This addition to source tree is
1022: required by some incompatibility between gnuplot releases;

1070: With STATIC, next variables created by '->' are static;
1071: - PROTECT and UNPROTECT are added to protect variables against write
1072: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1073: versions of PROTECT and UNPROTECT that only deal with global variables
1074: (see RCL/SAVE);
1075: - variable management routines have been rewritten. The new ones are
1076: uncompatible with the old ones. Before these changes, a local variable
1077: was exported to a child subroutine, but cannot be modified into this
1078: child subroutine. Now, a local variable is accessible only in its subroutine;
1079: - SAVE intrinsic is added to manipulate global variables;

1092: mutexes and several terminated child process cannot be closed by the
1093: operating system);
1094: - minor bug fixed in SCLS (mistake between main and auxiliary axes);
1095: - variables are now written in rpl-core file;
1096: - NEG is modified to return 0 instead -0 when its argument is real or complex
1097: number;
1098: - ROW+ intrinsic can now be used on empty matrix without dimension error:
1099: [[]] 1 [[ 1 2 ]] row+;
1100: - major bug is fixed in SUB intrinsic. It only occurs with lists when
1101: it tries to returns invalid elements like { } 1 2 sub;

1462: { "automatic" } (default);
1463: - a minor bug (in last stack) is fixed in AXES intrinsic
1464: - flag 52 is used to automatically update graphics;
1465: - man pages are updated;
1466: - evaluation() is modified to perform evaluation of expressions that contain
1467: '=';
1468: - a minor bug is fixed in AXES intrinsic;
1469: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1470: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1471: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1472: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1473: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;
1474: - PLOTTER is added to draw statistical clouds with lines;
1475: - C and H source files now include vim parameters;
1476: - vim syntax file is modified to include new intrinsics;
1477: - static archive is modified to include all required libraries needed by
1478: RPL/2.
1479: * Sun May 4 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6i (RPL/2)
1480: - '=' is added and tested;
1481: - XCOL and YCOL are added;
1482: - a minor bug in analyse_syntaxique() is fixed;
1483: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1484: structure. ELSE is modified to return an error when ELSE appears in
1485: an ELSE/END structure;
1486: - a major bug is fixed in CYCLE;
1487: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1488: sequencer continues after the end of this loop;
1489: - SCLS is added;
1490: - DRWS now uses COLS to draw 2D graphics;
1491: - PPAR and SPAR are written. SPAR returns a list that contains the
1492: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1493: statistical variable, or "DISABLED" if its type is not one of the type of
1494: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1495: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1496: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1497: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1498: disabled. Arguments of EXTERNAL are case sensitive because the external
1499: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1500: of known external functions but add the new list to the last. { "all" }
1501: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1502: external names of the known functions;
1503: - mkrplso.in is modified.
1504: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1505: - vim syntax file is upgraded;
1506: - a minor mistake is fixed in recherche_instruction_suivante();
1507: - some minor memory leaks are fixed in recherche_type() function. They only
1508: occurs when a syntax error is detected;
1509: - #error and #warning preprocessor macros are added;
1510: - INCR and DECR are written (with integer or variable argument);
1511: - CSWP and RSWP are added and tested;
1512: - a minor bug is fixed in analyse.c;
1513: - DEBIAN/control is added to build debian package;
1514: - SCALE is fixed and improved ("automatic" keyword);
1515: - PUTC and PUTR new intrinsics are added.
1516: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1517: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1518: VISIT does not find a name in level 1;
1519: - configure.in script is modified to add a new test (--enable-debug
1520: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1521: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1522: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1523: 'MATRIX' { 2 2 3 } GETR;
1524: - LOGSCALE intrinsic is improved and now, it can be used as
1525: { "main" "auxiliary" X Y } LOGSCALE;
1526: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1527: same than AXES:
1528: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1529: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1530: { { -10 10 } "automatic" } SCALE.
1531: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1532: because it changes only the dimension of the screen. To have a logarithmic
1533: scale, you must use LOGSCALE intrinsic:
1534: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1535: screen on second scale;
1536: - { X X } autoscale and { Y Y } logscale are now invalid;
1537: - *D is added (depth multiplication, for 3D graphics);
1538: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1539: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1540: - a major bug is fixed in GETI instrinsic when it is used with a name
1541: that contains a matrix or a vector (bad upper bounds conditions in
1542: incrementation);
1543: - DISP intrinsic now uses the 33-th flag. When it is not set
1544: (default), a final carriage return is sent to the terminal;
1545: - AXES intrinsic only takes a list that can contains the keywork
1546: "main" or "auxiliary". Before this modification, this keyword was in
1547: the first stack level;
1548: - vim syntax file is upgraded;
1549: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1550: option;
1551: - LAST is now disabled in the main loop of INT intrinsic;
1552: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1553: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1554: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1555: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1556: in 0);
1557: - LAST is disabled in the main loop of DRAW intrinsic;
1558: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1559: evaluation of an equation, the system stack is returned corrupted to the
1560: sequencer;
1561: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1562: of a loop are not integer or real.
1563: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1564: - the compilation stage aborts with an error message when two definitions
1565: have the same name. To improve the compilation() subroutine, I have to
1566: add some tests in gestion_variables.c;
1567: - recherche_type() subroutine ad some other connex subroutines are improved.
1568: Now, some syntax errors about object are caught and do not perform sequencer
1569: hangup;

1571: - Makefile.am's and configure.in scripts are improved.
1572: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1573: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1574: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1575: the boxwidth, 1 by default);
1576: - recherche_type() is rewritten to be faster;
1577: - gsl is upgraded (release 1.3);
1578: - ncurses is upgraded and patched (release 5.3);
1579: - recherche_instruction_suivante() is fixed (string research with included
1580: '"') and rewritten to be faster;

1591: - a minor bug is fixed in evaluation subroutine;
1592: - vim syntax file is improved;
1593: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1594: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1595: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1596: is a quick and dirty workaround...);
1597: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1598: - rplconvert is improved.
1599: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1708: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1709: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1710: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1711:
1712: Newton:[~/rpl/rpl] > time make install
