! 4: calling thread;
1.137 bertrand 5: - static variables are now written in automatic variables tree;
1.136 bertrand 6: - major bug is fixed in STO intrinsic. STO returns an error when it has
7: to create a global variable if intrinsic none (default) is set.

180: by a new feature in glibc.
181: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
182: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
183: "ALL" IMPLICIT when it runs in interactive mode;
184: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
185: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
186: to use SAVE to manipulate global variables;
187: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
188: subroutines;
189: - fix major memory access violation in evaluation subroutine. Only occurs
190: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
191: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
192: when X was a vector or a table.
1.63 bertrand 193: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

1.52 bertrand 222: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
223: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
224: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
225: corruption. As internal memory management have been improved, a best fit
226: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 227: - gnuplot is upgraded to 4.4.1;
228: - deadlock is fixed in signal handlers: same mutex was used in standard
229: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
230: and signal handlers. A new signal handler specific mutex is added;
231: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
232: that has to be evaluated by ->NUM;
1.49 bertrand 233: - rplfile build process is modify to be sure that rplfile is not modified
234: after rpl build stage (to be sure that rplfile checksum is not modified after
235: rpl compilation);
1.51 bertrand 236: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
237: modified to remove yacc code and renamed;
1.47 bertrand 238: - some workarounds have been written to not use buggy klibc SystemV IPCS.
239: ABORT now works on eComStation;
240: - sqlite is upgraded to 3.7.2;
241: - bug is fixed in software interrupts. When both process have different PID,
242: parent process was not interrupted if it is not group master process. To fix
243: this bug, SIGINJECT signal is not sent by child process but by control thread
244: in parent process;
1.46 bertrand 245: - minor bug is fixed in data injection (POKE) that does not work as expected
246: when child process is protected by NRPROC.
1.44 bertrand 247: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 248: - --enable-sysv-sems is added to configure script to use SystemV semaphores
249: functions instead of POSIX functions. This function is disabled or forced on
250: systems that does not provide correct POSIX or SysV semaphores subsystem;
251: - a dirty but not quick patch is written to workaround broken siginfo
252: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 253: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 254: (Unix PID);
1.41 bertrand 255: - some OpenBSD's hacks are added;
256: - broken siginfo->si_pid field is now checked by configure script;

1.40 bertrand 261: or freeaddrinfo;
1.39 bertrand 262: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
263: - major bug is fixed in CHR intrinsic when obtained character is not printable;

1.37 bertrand 271: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 272: - units is upgraded to 1.88;
273: - another major bug is fixed in the same variable creation subroutine.
274: Level 0 and 1 variables adresses were swapped when a global variable masked
275: a name of RPL/2 routine;
1.35 bertrand 276: - major bug is fixed in global variable creation subroutine. When a global
277: variable was created and when a local variable existed with the same name,
278: computed address of global variable was wrong;
279: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
280: is forced in front of all libraries.
1.34 bertrand 281: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
282: - BACKTRACE intrinsic is added;
283: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
284: when this structure is included in IFERR/THEN/END structure and when an error is
285: caught;
286: - major bug is fixed in analyse() subroutine. When evaluation() returned error
287: in a compiled program, analyse() caught this error twice and randomly aborted
288: with a segmentation error;
289: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
290: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
291: signals;
292: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
293: matrix.
1.33 bertrand 294: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

312: format in FCH (file descriptor) and SCK (socket descriptor);
313: - debug routines are improved;
314: - PROCID is added;
315: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
316: and to not use swap;
1.26 bertrand 317: - major bug is fixed in sql support. SQL connections were closed in all chield
318: process;
319: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
320: discovered in Solaris thread safe allocators (libmalloc and libumem) that

325: should);
326: - minor bugs are fixed in interruptions.c (semaphores values when error is
327: caught);
328: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
329: created by SPAWN;
330: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
331: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 332: - ONEXIT is renamed in ATEXIT;
333: - ONEXIT new intrinsic is added.
1.20 bertrand 334: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)

1.13 bertrand 386: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
387: - in formatted file, string format returned a variable length string even if
388: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 389: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 390: - keyed access files support is added. Currently, only formatted files are

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

452: script file contains a multibyte character;
453: - IN intrinsic is added;
454: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
455: returned false ;
456: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
457: programs;
458: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
459: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

469: - DISP now locks stdout;
470: - rpliconv is added to replace standard iconv provided by operating system.
471: Indeed, conversion between different encodages requires transliteration
472: that is not offered by some iconv utility;
473: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
474: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
475: not be found), SYSEVAL enters in a dead lock;
476: - fprintf is replaced by some functions that allow transliterations between
477: locales;
478: - '"' can now be used in strings ("\"");
479: - iconv is called with -c in preprocessor stage. It is done to write
480: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
481: - double free is fixed in liberation() (type SQL, only occurs when locale is
482: set);
483: - LOCALIZATION, UCASE and LCASE are added;
484: - major bug is fixed in EXIT intrinsic that was able to return a false
485: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);

493: - pipe() is overwritten by a macro to avoid a system error. Communication
494: between process are done with pipes and these pipes are managed by a
495: specific asynchrone thread. If a script try to create more threads than
496: management thread can destroy, you can quickly achieve maximum number of
497: opened files and pipe() shall return a system error. This macro tries to create
498: pipes. If pipe() function returns an error, macro waits and retries. If
499: number of retries is greater than a hardcoded value, macro returns an error;
500: - major bug (deadlock) is fixed in process and thread management. I hope
501: this bug shall be the last one;
502: - major bug is fixed in DET intrinsic (determinant was computed without LU
503: diagonalization);

507: - some bugfixes are added in process management;
508: - all process management is rewritten to avoid usage of defunct process
509: or thread number;
510: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
511: was called before a pending interruption5 (SIGFSTOP), signal handler uses
512: a freed semaphore and corrupts heap;
513: - CLRERR is added to erase previous errors;
514: - ERRN and ERRM return exception message and number;
515: - major bug is fixed in interruptions.c. All signal are now bufferised
516: when semaphore_liste_threads is null to avoid deadlock. This bug only
517: occured when STOP was sent to a dying thread or process (when this thread or
518: process was running retrait_thread());
519: - matrix rank is computed before matrix inversion;
520: - file locks are added to stdin and stdout. stderr is not locked because
521: all messages written by signal handlers are sent to stderr;
522: - configure.in script is modified to test gcc version and avoid a bug in
523: gcc older than 4.4;

664: that all programs that worked with old SQL intrinsic can now work with
665: SQLQUERY. With all new programs, you can open a real connection to databases;
666: - NRPROC is added. This new intrinsic is used to catch error from child
667: process. Without NRPROC, any errors returned by child process cause
668: main process to abort;
669: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
670: starts a new process). There are no mutexes in RPL/2 because all spawned process
671: use specific context. Nevertheless, shared variables and associated mutexes
672: should be added;

759: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
760: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
761: workaround for this major bug. Nevertheless, all others capabilities seems to
762: work fine;
763: - '->' is modified to return error when program tries to initialiaze two
764: variables with the same name like

811: before starting interrupt evaluation;
812: - -f parameter is added when iconv is called;
813: - as old file program was bugged, a new option is added to configure script.
814: When configure is called with --disable-encoding-autodetection, make does not
815: try to detect source encoding. Please, do not use if RPL/2 can be built
816: without this option !
817: - new garbage collector (and more efficient) is written;

821: - -p option is added. With this option, all scripts are compiled before
822: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
823: 40% faster;
824: - read and write operations in pipe() are rewritten to be sure that such
825: operations are atomic;
826: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1019: static variable can be transformed into volatile with VOLATILE.
1020: With STATIC, next variables created by '->' are static;
1021: - PROTECT and UNPROTECT are added to protect variables against write
1022: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1023: versions of PROTECT and UNPROTECT that only deal with global variables
1024: (see RCL/SAVE);
1025: - variable management routines have been rewritten. The new ones are
1026: uncompatible with the old ones. Before these changes, a local variable
1027: was exported to a child subroutine, but cannot be modified into this
1028: child subroutine. Now, a local variable is accessible only in its subroutine;
1029: - SAVE intrinsic is added to manipulate global variables;

1470: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1471: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1472: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1473: 'MATRIX' { 2 2 3 } GETR;
1474: - LOGSCALE intrinsic is improved and now, it can be used as
1475: { "main" "auxiliary" X Y } LOGSCALE;
1476: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1477: same than AXES:
1478: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1479: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1480: { { -10 10 } "automatic" } SCALE.
1481: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1482: because it changes only the dimension of the screen. To have a logarithmic
1483: scale, you must use LOGSCALE intrinsic:
1484: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1485: screen on second scale;
1486: - { X X } autoscale and { Y Y } logscale are now invalid;
1487: - *D is added (depth multiplication, for 3D graphics);
1488: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1489: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1490: - a major bug is fixed in GETI instrinsic when it is used with a name
1491: that contains a matrix or a vector (bad upper bounds conditions in
1492: incrementation);
1493: - DISP intrinsic now uses the 33-th flag. When it is not set
1494: (default), a final carriage return is sent to the terminal;
1495: - AXES intrinsic only takes a list that can contains the keywork
1496: "main" or "auxiliary". Before this modification, this keyword was in
1497: the first stack level;
1498: - vim syntax file is upgraded;
1499: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1500: option;
1501: - LAST is now disabled in the main loop of INT intrinsic;
1502: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

1504: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1505: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1506: in 0);
1507: - LAST is disabled in the main loop of DRAW intrinsic;
1508: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1509: evaluation of an equation, the system stack is returned corrupted to the
1510: sequencer;
1511: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1512: of a loop are not integer or real.
1513: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1515: have the same name. To improve the compilation() subroutine, I have to
1516: add some tests in gestion_variables.c;
1517: - recherche_type() subroutine ad some other connex subroutines are improved.
1518: Now, some syntax errors about object are caught and do not perform sequencer

1523: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1524: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1542: - vim syntax file is improved;
1543: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1544: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1545: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1546: is a quick and dirty workaround...);
1547: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1548: - rplconvert is improved.
1549: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
