7: calling thread;
1.137 bertrand 8: - static variables are now written in automatic variables tree;
1.136 bertrand 9: - major bug is fixed in STO intrinsic. STO returns an error when it has

183: by a new feature in glibc.
184: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
185: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
186: "ALL" IMPLICIT when it runs in interactive mode;
187: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
188: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
189: to use SAVE to manipulate global variables;
190: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
191: subroutines;
192: - fix major memory access violation in evaluation subroutine. Only occurs
193: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
194: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
195: when X was a vector or a table.
1.63 bertrand 196: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

208: - Ncurses is upgraded to 5.8;
209: - ALARM is fixed by filling isdst field;
210: - catch ECONNRESET in write intrinsic to return an execution error instead of
211: system one;

1.52 bertrand 225: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
226: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
227: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
228: corruption. As internal memory management have been improved, a best fit
229: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 230: - gnuplot is upgraded to 4.4.1;
231: - deadlock is fixed in signal handlers: same mutex was used in standard
232: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
233: and signal handlers. A new signal handler specific mutex is added;
234: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
235: that has to be evaluated by ->NUM;
1.49 bertrand 236: - rplfile build process is modify to be sure that rplfile is not modified
237: after rpl build stage (to be sure that rplfile checksum is not modified after
238: rpl compilation);
1.51 bertrand 239: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
240: modified to remove yacc code and renamed;
1.47 bertrand 241: - some workarounds have been written to not use buggy klibc SystemV IPCS.
242: ABORT now works on eComStation;
243: - sqlite is upgraded to 3.7.2;
244: - bug is fixed in software interrupts. When both process have different PID,
245: parent process was not interrupted if it is not group master process. To fix
246: this bug, SIGINJECT signal is not sent by child process but by control thread
247: in parent process;
1.46 bertrand 248: - minor bug is fixed in data injection (POKE) that does not work as expected
249: when child process is protected by NRPROC.
1.44 bertrand 250: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 251: - --enable-sysv-sems is added to configure script to use SystemV semaphores
252: functions instead of POSIX functions. This function is disabled or forced on
253: systems that does not provide correct POSIX or SysV semaphores subsystem;
254: - a dirty but not quick patch is written to workaround broken siginfo
255: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 256: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 257: (Unix PID);
1.41 bertrand 258: - some OpenBSD's hacks are added;
259: - broken siginfo->si_pid field is now checked by configure script;

1.40 bertrand 264: or freeaddrinfo;
1.39 bertrand 265: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
266: - major bug is fixed in CHR intrinsic when obtained character is not printable;

1.37 bertrand 274: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 275: - units is upgraded to 1.88;
276: - another major bug is fixed in the same variable creation subroutine.
277: Level 0 and 1 variables adresses were swapped when a global variable masked
278: a name of RPL/2 routine;
1.35 bertrand 279: - major bug is fixed in global variable creation subroutine. When a global
280: variable was created and when a local variable existed with the same name,
281: computed address of global variable was wrong;
282: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
283: is forced in front of all libraries.
1.34 bertrand 284: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
285: - BACKTRACE intrinsic is added;
286: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
287: when this structure is included in IFERR/THEN/END structure and when an error is
288: caught;
289: - major bug is fixed in analyse() subroutine. When evaluation() returned error
290: in a compiled program, analyse() caught this error twice and randomly aborted
291: with a segmentation error;
292: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
293: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
294: signals;
295: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
296: matrix.
1.33 bertrand 297: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

315: format in FCH (file descriptor) and SCK (socket descriptor);
316: - debug routines are improved;
317: - PROCID is added;
318: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
319: and to not use swap;
1.26 bertrand 320: - major bug is fixed in sql support. SQL connections were closed in all chield
321: process;
322: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
323: discovered in Solaris thread safe allocators (libmalloc and libumem) that
324: are first fit class allocators. Solaris libmtmalloc works better and is
325: a best fit class allocator but its performance is poor than ptmalloc3

328: should);
329: - minor bugs are fixed in interruptions.c (semaphores values when error is
330: caught);
331: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
332: created by SPAWN;
333: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
334: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 335: - ONEXIT is renamed in ATEXIT;

390: - in formatted file, string format returned a variable length string even if
391: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 392: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 393: - keyed access files support is added. Currently, only formatted files are

442: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
443: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
444: signals sent to main process were not caught because DAEMON did not replace
445: old pid by new one;
446: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
447: evaluation when an error is reported from a subroutine in another subroutine.
448: For example, error was not caught in following program when it is executed with
449: -p option :
450: TEST << iferr TEST2 then end >>
451: TEST2 << 0 inv >>
452: - major bug is fixed in variable management. Some local variables were

455: script file contains a multibyte character;
456: - IN intrinsic is added;
457: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
458: returned false ;
459: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
460: programs;
461: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
462: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
463: strings were never closed;
464: - some bugs have been fixed in file management;

470: - major bug is fixed in OPEN (TCP/IPv4 sockets).
471: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
472: - DISP now locks stdout;
473: - rpliconv is added to replace standard iconv provided by operating system.
474: Indeed, conversion between different encodages requires transliteration
475: that is not offered by some iconv utility;
476: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
477: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
478: not be found), SYSEVAL enters in a dead lock;
479: - fprintf is replaced by some functions that allow transliterations between
480: locales;
481: - '"' can now be used in strings ("\"");
482: - iconv is called with -c in preprocessor stage. It is done to write
483: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
484: - double free is fixed in liberation() (type SQL, only occurs when locale is
485: set);
486: - LOCALIZATION, UCASE and LCASE are added;
487: - major bug is fixed in EXIT intrinsic that was able to return a false
488: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);

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

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

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

1028: - variable management routines have been rewritten. The new ones are
1029: uncompatible with the old ones. Before these changes, a local variable
1030: was exported to a child subroutine, but cannot be modified into this
1031: child subroutine. Now, a local variable is accessible only in its subroutine;

1469: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1470: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1471: VISIT does not find a name in level 1;
1472: - configure.in script is modified to add a new test (--enable-debug
1473: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1474: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1475: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1476: 'MATRIX' { 2 2 3 } GETR;
1477: - LOGSCALE intrinsic is improved and now, it can be used as
1478: { "main" "auxiliary" X Y } LOGSCALE;
1479: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1480: same than AXES:
1481: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1482: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1483: { { -10 10 } "automatic" } SCALE.
1484: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1485: because it changes only the dimension of the screen. To have a logarithmic
1486: scale, you must use LOGSCALE intrinsic:
1487: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1488: screen on second scale;
1489: - { X X } autoscale and { Y Y } logscale are now invalid;
1490: - *D is added (depth multiplication, for 3D graphics);
1491: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1492: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1493: - a major bug is fixed in GETI instrinsic when it is used with a name
1494: that contains a matrix or a vector (bad upper bounds conditions in
1495: incrementation);
1496: - DISP intrinsic now uses the 33-th flag. When it is not set
1497: (default), a final carriage return is sent to the terminal;
1498: - AXES intrinsic only takes a list that can contains the keywork
1499: "main" or "auxiliary". Before this modification, this keyword was in
1500: the first stack level;
1501: - vim syntax file is upgraded;
1502: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1503: option;
1504: - LAST is now disabled in the main loop of INT intrinsic;
1505: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1506: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1507: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1508: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1509: in 0);
1510: - LAST is disabled in the main loop of DRAW intrinsic;
1511: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1512: evaluation of an equation, the system stack is returned corrupted to the
1513: sequencer;
1514: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1515: of a loop are not integer or real.
1516: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1517: - the compilation stage aborts with an error message when two definitions
1518: have the same name. To improve the compilation() subroutine, I have to
1519: add some tests in gestion_variables.c;
1520: - recherche_type() subroutine ad some other connex subroutines are improved.
1521: Now, some syntax errors about object are caught and do not perform sequencer
1522: hangup;
1523: - readline is upgraded (minor compilation bug with recent gcc);
1524: - Makefile.am's and configure.in scripts are improved.
1525: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1526: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1527: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1528: the boxwidth, 1 by default);
1529: - recherche_type() is rewritten to be faster;
1530: - gsl is upgraded (release 1.3);
1531: - ncurses is upgraded and patched (release 5.3);
1532: - recherche_instruction_suivante() is fixed (string research with included
1533: '"') and rewritten to be faster;
1534: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1535: segfault.
1536: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1544: - a minor bug is fixed in evaluation subroutine;
1545: - vim syntax file is improved;
1546: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1547: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1548: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1549: is a quick and dirty workaround...);
1550: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1551: - rplconvert is improved.
1552: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1662: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1663: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1664:
1665: Newton:[~/rpl/rpl] > time make install
