1: * Tue Dec 18 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.13 (RPL/2)
2: - minor bug is fixed in TOKENIZE intrinsic instruction. TOKENIZE did not work on
3: a copy of input string;
4: - major bug (segfault) is fixed in liste_variables(). It only occurs
5: when this function is called with shared variables;
6: - all internal data are now stored in 64 bits wide integers (even is 32 bits
7: ABI is selected);
8: - major bug is fixed in recherche_instruction_suivante(). In some
9: circumstances, this function can return a spurious error;
10: - new NATIVE*(*) data format is added. By default, native*(*) is used
11: to write data without precision loss. It can also be used to write
12: complex objects like expressions, lists or tables;
13: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
14: internal value was good but RPL/2 was not able to correctly display
15: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented
16: in integer. All abs(), fabs() and labs() present in source code have ben checked
17: to avoid this kind of bug;
18: - unformatted sockets are now usable as unformatted files;
19: - BACKSPACE now runs on unformatted file;
20: - major bug is fixed in BACKSPACE that didn't check if '"' characters were
21: escaped;

26: destacked when execution error occurs;
27: - major bug is fixed in READ (socket interface);
28: - minor bug is fixed in analyse_flux().

59: interrupt a loop from a subroutine within a compiled programm;
60: - workaround to avoid strange bug on slow network is written in READ
61: intrinsic;
62: - CRITICAL/END structure is added. When program enters in a critical
63: section, all other threads of the same process sleep until program leaves
64: critical section.

143: - recherche_type() did not convert huge integer in real. Now,
144: 18446744072742037448 is converted into real as value cannot be stored in
145: RPL/2 integer type;
146: - WFSOCK is modified to handle unconnected sockets;
147: - REGEX is added;
148: - RESTART is added (execvp() on main RPL/2 process);

150: a real copy. Now, struct_mutex contains locks owner. On Linux or Solaris (for
151: example), it is possible to lock mutex from a thread and unlock the same mutex
152: from another thread. On NetBSD, system crashes.
153: * Mon Nov 21 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.4 (RPL/2)

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

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

290: parent process was not interrupted if it is not group master process. To fix
291: this bug, SIGINJECT signal is not sent by child process but by control thread
292: in parent process;
293: - minor bug is fixed in data injection (POKE) that does not work as expected
294: when child process is protected by NRPROC.
295: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
296: - --enable-sysv-sems is added to configure script to use SystemV semaphores
297: functions instead of POSIX functions. This function is disabled or forced on
298: systems that does not provide correct POSIX or SysV semaphores subsystem;
299: - a dirty but not quick patch is written to workaround broken siginfo
300: structures. This patch has been successfully tested. It uses a segment of
301: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
302: (Unix PID);
303: - some OpenBSD's hacks are added;
304: - broken siginfo->si_pid field is now checked by configure script;
305: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

322: Level 0 and 1 variables adresses were swapped when a global variable masked
323: a name of RPL/2 routine;
324: - major bug is fixed in global variable creation subroutine. When a global
325: variable was created and when a local variable existed with the same name,
326: computed address of global variable was wrong;
327: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
328: is forced in front of all libraries.
329: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
330: - BACKTRACE intrinsic is added;
331: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
332: when this structure is included in IFERR/THEN/END structure and when an error is
333: caught;
334: - major bug is fixed in analyse() subroutine. When evaluation() returned error
335: in a compiled program, analyse() caught this error twice and randomly aborted
336: with a segmentation error;
337: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
338: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
339: signals;
340: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
341: matrix.
342: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
343: - minor bug is fixed in evaluation() subroutine. With this patch, same program
344: returns same result with or without -p flag;

346: - openssl is upgraded to 1.0.0a;
347: - interrupt stacks are now FIFO instead of LIFO;
348: - debug memory allocation subroutines are improved to run in multithreaded
349: programs;
350: - some memory leaks are fixed in process management (SPAWN and DETACH);
351: - version verification is added to shared objects;
352: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
353: linux (false mremap() prototype);
354: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
355: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
356: - all '-' are replaced by '_' in random generator list;

360: format in FCH (file descriptor) and SCK (socket descriptor);
361: - debug routines are improved;
362: - PROCID is added;
363: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
364: and to not use swap;
365: - major bug is fixed in sql support. SQL connections were closed in all chield
366: process;
367: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
368: discovered in Solaris thread safe allocators (libmalloc and libumem) that
369: are first fit class allocators. Solaris libmtmalloc works better and is
370: a best fit class allocator but its performance is poor than ptmalloc3
371: performance;
372: - major bug is fixed in ROW+ intrinsic (new row was not added where it
373: should);
374: - minor bugs are fixed in interruptions.c (semaphores values when error is
375: caught);
376: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
377: created by SPAWN;
378: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
379: ATEXIT. If it receives SIGFABORT, it does not;

387: information about shared variable was not copied to new processus structure;
388: - some little memory leaks are fixed in evaluation(), recherche_type() and
389: sequenceur(). They only occured when syntax error were caught;
390: - IMPLICIT causes execution error instead system error;
391: - Hurd support is improved but currently broken because Hurd does not support
392: SIG_INFO. Work in progress;
393: - OpenBSD specific support is removed from sources;
394: - support for Mac OS X and Windows/Cygwin is added.
395: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

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

446: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
447: each execution (md5 and sha1 sums) to enhance security. If one of these tools
448: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
449: on a non recoverable system error;
450: - openssl and sqlite3 libraries are added;
451: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
452: variable indicates RPL/2 root directory. If it is not set, root path
453: is given by configure script (d_exec_path);
454: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

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

496: TEST2 << 0 inv >>
497: - major bug is fixed in variable management. Some local variables were
498: seen as global ones;

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

515: - major bug is fixed in OPEN (TCP/IPv4 sockets).
516: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
517: - DISP now locks stdout;
518: - rpliconv is added to replace standard iconv provided by operating system.
519: Indeed, conversion between different encodages requires transliteration
520: that is not offered by some iconv utility;
521: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
522: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

524: - fprintf is replaced by some functions that allow transliterations between
525: locales;
526: - '"' can now be used in strings ("\"");
527: - iconv is called with -c in preprocessor stage. It is done to write
528: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
529: - double free is fixed in liberation() (type SQL, only occurs when locale is
530: set);
531: - LOCALIZATION, UCASE and LCASE are added;

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

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

644: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
645: process is killed;
646: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
647: know typeof() intrinsic function. This function is not standard but exists
648: under Sun Studio, gcc, and maybe some others compilers. If this function does

691: static variable that is shared by multiple threads;
692: - '->' intrinsic is improved. All object copies have been avoided;
693: - -n flag is added to catch HUP signal. stderr and stdout are redirected
694: to a file, stdin is redirected to /dev/null when control process is killed;

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

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

869: - -p option is added. With this option, all scripts are compiled before
870: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
871: 40% faster;
872: - read and write operations in pipe() are rewritten to be sure that such
873: operations are atomic;

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

1518: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1519: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1520: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1521: 'MATRIX' { 2 2 3 } GETR;
1522: - LOGSCALE intrinsic is improved and now, it can be used as
1523: { "main" "auxiliary" X Y } LOGSCALE;
1524: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1525: same than AXES:
1526: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1527: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1528: { { -10 10 } "automatic" } SCALE.
1529: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1530: because it changes only the dimension of the screen. To have a logarithmic
1531: scale, you must use LOGSCALE intrinsic:
1532: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1533: screen on second scale;
1534: - { X X } autoscale and { Y Y } logscale are now invalid;
1535: - *D is added (depth multiplication, for 3D graphics);
1536: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1537: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1538: - a major bug is fixed in GETI instrinsic when it is used with a name
1539: that contains a matrix or a vector (bad upper bounds conditions in
1540: incrementation);
1541: - DISP intrinsic now uses the 33-th flag. When it is not set
1542: (default), a final carriage return is sent to the terminal;
1543: - AXES intrinsic only takes a list that can contains the keywork
1544: "main" or "auxiliary". Before this modification, this keyword was in
1545: the first stack level;
1546: - vim syntax file is upgraded;
1547: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1548: option;
1549: - LAST is now disabled in the main loop of INT intrinsic;
1550: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

1552: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1553: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1554: in 0);
1555: - LAST is disabled in the main loop of DRAW intrinsic;
1556: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1557: evaluation of an equation, the system stack is returned corrupted to the
1558: sequencer;
1559: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1560: of a loop are not integer or real.
1561: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1563: have the same name. To improve the compilation() subroutine, I have to
1564: add some tests in gestion_variables.c;
1565: - recherche_type() subroutine ad some other connex subroutines are improved.
1566: Now, some syntax errors about object are caught and do not perform sequencer

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