Annotation of rpl/ChangeLog, revision 1.162
1.154 bertrand 1: * Tue Dec 18 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.13 (RPL/2)
1.162 ! bertrand 2: - major bug is fixed in recherche_instruction_suivante(). In some
! 3: circumstances, this function can return a spurious error;
1.161 bertrand 4: - new NATIVE*(*) data format is added. By default, native*(*) is used
5: to write data without precision loss. It can also be used to write
6: complex objects like expressions, lists or tables;
1.160 bertrand 7: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
8: internal value was good but RPL/2 was not able to correctly display
9: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented
10: in integer. All abs(), fabs() and labs() present in source code have ben checked
11: to avoid this kind of bug;
1.159 bertrand 12: - unformatted sockets are now usable as unformatted files;
1.158 bertrand 13: - BACKSPACE now runs on unformatted file;

1.155 bertrand 17: - transliteration is avoid in rpl-core file generation to authorize core
18: creation even if a transliteration error is caught;
19: - major bug is fixed in evaluation(). System stack was not correctly
20: destacked when execution error occurs;
1.154 bertrand 21: - major bug is fixed in READ (socket interface);
22: - minor bug is fixed in analyse_flux().

46: calling thread;
1.144 bertrand 47: - static variables are now written in a variables tree;
1.136 bertrand 48: - major bug is fixed in STO intrinsic. STO returns an error when it has
49: to create a global variable if intrinsic none (default) is set.

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

1.52 bertrand 264: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
265: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
266: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
267: corruption. As internal memory management have been improved, a best fit
268: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 269: - gnuplot is upgraded to 4.4.1;
270: - deadlock is fixed in signal handlers: same mutex was used in standard
271: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
272: and signal handlers. A new signal handler specific mutex is added;
273: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
274: that has to be evaluated by ->NUM;
1.49 bertrand 275: - rplfile build process is modify to be sure that rplfile is not modified
276: after rpl build stage (to be sure that rplfile checksum is not modified after

281: ABORT now works on eComStation;
282: - sqlite is upgraded to 3.7.2;
283: - bug is fixed in software interrupts. When both process have different PID,
284: parent process was not interrupted if it is not group master process. To fix
285: this bug, SIGINJECT signal is not sent by child process but by control thread
286: in parent process;
1.46 bertrand 287: - minor bug is fixed in data injection (POKE) that does not work as expected
288: when child process is protected by NRPROC.
1.44 bertrand 289: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 290: - --enable-sysv-sems is added to configure script to use SystemV semaphores
291: functions instead of POSIX functions. This function is disabled or forced on
292: systems that does not provide correct POSIX or SysV semaphores subsystem;
293: - a dirty but not quick patch is written to workaround broken siginfo
294: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 295: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 296: (Unix PID);
1.41 bertrand 297: - some OpenBSD's hacks are added;
298: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 299: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

1.39 bertrand 302: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 303: or freeaddrinfo;
1.39 bertrand 304: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
305: - major bug is fixed in CHR intrinsic when obtained character is not printable;
306: - Lapack is upgraded to 3.2.2;
1.37 bertrand 307: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
1.36 bertrand 308: - TOKENIZE is now able to convert escape sequences;
309: - ATPOKE and CLRATPOKE new intrinsics are added;

1.37 bertrand 313: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 314: - units is upgraded to 1.88;
315: - another major bug is fixed in the same variable creation subroutine.
316: Level 0 and 1 variables adresses were swapped when a global variable masked
317: a name of RPL/2 routine;
1.35 bertrand 318: - major bug is fixed in global variable creation subroutine. When a global
319: variable was created and when a local variable existed with the same name,
320: computed address of global variable was wrong;
321: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
322: is forced in front of all libraries.
1.34 bertrand 323: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
324: - BACKTRACE intrinsic is added;
325: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
326: when this structure is included in IFERR/THEN/END structure and when an error is
327: caught;
328: - major bug is fixed in analyse() subroutine. When evaluation() returned error
329: in a compiled program, analyse() caught this error twice and randomly aborted
330: with a segmentation error;
331: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
332: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
333: signals;

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

367: should);
368: - minor bugs are fixed in interruptions.c (semaphores values when error is
369: caught);
370: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process

381: information about shared variable was not copied to new processus structure;
1.19 bertrand 382: - some little memory leaks are fixed in evaluation(), recherche_type() and
383: sequenceur(). They only occured when syntax error were caught;
384: - IMPLICIT causes execution error instead system error;

386: SIG_INFO. Work in progress;
387: - OpenBSD specific support is removed from sources;
388: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 389: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

1.13 bertrand 428: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
429: - in formatted file, string format returned a variable length string even if
430: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 431: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 432: - keyed access files support is added. Currently, only formatted files are

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

494: script file contains a multibyte character;
495: - IN intrinsic is added;
496: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
497: returned false ;
498: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
499: programs;
500: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
501: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
502: strings were never closed;
503: - some bugs have been fixed in file management;

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

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

553: was called before a pending interruption5 (SIGFSTOP), signal handler uses
554: a freed semaphore and corrupts heap;
555: - CLRERR is added to erase previous errors;
556: - ERRN and ERRM return exception message and number;
557: - major bug is fixed in interruptions.c. All signal are now bufferised
558: when semaphore_liste_threads is null to avoid deadlock. This bug only
559: occured when STOP was sent to a dying thread or process (when this thread or
560: process was running retrait_thread());
561: - matrix rank is computed before matrix inversion;
562: - file locks are added to stdin and stdout. stderr is not locked because
563: all messages written by signal handlers are sent to stderr;

638: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
639: process is killed;
640: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
641: know typeof() intrinsic function. This function is not standard but exists
642: under Sun Studio, gcc, and maybe some others compilers. If this function does
643: not exist on your compiler, you can change its definition by old one in

685: static variable that is shared by multiple threads;
686: - '->' intrinsic is improved. All object copies have been avoided;
687: - -n flag is added to catch HUP signal. stderr and stdout are redirected
688: to a file, stdin is redirected to /dev/null when control process is killed;
689: - a mutex is added to each object (before this modification,

705: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
706: that all programs that worked with old SQL intrinsic can now work with
707: SQLQUERY. With all new programs, you can open a real connection to databases;
708: - NRPROC is added. This new intrinsic is used to catch error from child
709: process. Without NRPROC, any errors returned by child process cause
710: main process to abort;
711: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
712: starts a new process). There are no mutexes in RPL/2 because all spawned process
713: use specific context. Nevertheless, shared variables and associated mutexes
714: should be added;

1064: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1065: versions of PROTECT and UNPROTECT that only deal with global variables
1066: (see RCL/SAVE);
1067: - variable management routines have been rewritten. The new ones are
1068: uncompatible with the old ones. Before these changes, a local variable
1069: was exported to a child subroutine, but cannot be modified into this
1070: child subroutine. Now, a local variable is accessible only in its subroutine;
1071: - SAVE intrinsic is added to manipulate global variables;

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

1563: - Makefile.am's and configure.in scripts are improved.
1564: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1565: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1566: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1567: the boxwidth, 1 by default);
1568: - recherche_type() is rewritten to be faster;
1569: - gsl is upgraded (release 1.3);
1570: - ncurses is upgraded and patched (release 5.3);
1571: - recherche_instruction_suivante() is fixed (string research with included
1572: '"') and rewritten to be faster;

1583: - a minor bug is fixed in evaluation subroutine;
1584: - vim syntax file is improved;
1585: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1586: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1587: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1588: is a quick and dirty workaround...);
1589: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1590: - rplconvert is improved.
