1: * Mon Apr 1 2013 BERTRAND Joël <rpl@systella.fr> rpl-4.1.13 (RPL/2)
2: - integer overflows have been fixed (NEG, ABS, minus);
3: - global variables can now be recalled from ATEXIT procedure;
4: - ATEXIT registered procedure is now executed even if program is stopped by
5: SIGINT;
6: - minor bug is fixed in TOKENIZE intrinsic instruction. TOKENIZE did not work on
7: a copy of input string;
8: - major bug (segfault) is fixed in liste_variables(). It only occurs
9: when this function is called with shared variables;
10: - all internal data are now stored in 64 bits wide integers (even is 32 bits
11: ABI is selected);
12: - major bug is fixed in recherche_instruction_suivante(). In some
13: circumstances, this function can return a spurious error;
14: - new NATIVE*(*) data format is added. By default, native*(*) is used
15: to write data without precision loss. It can also be used to write
16: complex objects like expressions, lists or tables;
17: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
18: internal value was good but RPL/2 was not able to correctly display
19: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented
20: in integer. All abs(), fabs() and labs() present in source code have ben checked
21: to avoid this kind of bug;
22: - unformatted sockets are now usable as unformatted files;
23: - BACKSPACE now runs on unformatted file;
24: - major bug is fixed in BACKSPACE that didn't check if '"' characters were

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

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

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

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

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

326: Level 0 and 1 variables adresses were swapped when a global variable masked
327: a name of RPL/2 routine;
328: - major bug is fixed in global variable creation subroutine. When a global
329: variable was created and when a local variable existed with the same name,
330: computed address of global variable was wrong;
331: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
332: is forced in front of all libraries.

334: - BACKTRACE intrinsic is added;
335: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
336: when this structure is included in IFERR/THEN/END structure and when an error is
337: caught;
338: - major bug is fixed in analyse() subroutine. When evaluation() returned error
339: in a compiled program, analyse() caught this error twice and randomly aborted
340: with a segmentation error;
341: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
342: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
343: signals;
344: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
345: matrix.
346: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
347: - minor bug is fixed in evaluation() subroutine. With this patch, same program
348: returns same result with or without -p flag;

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

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

393: sequenceur(). They only occured when syntax error were caught;
394: - IMPLICIT causes execution error instead system error;
395: - Hurd support is improved but currently broken because Hurd does not support
396: SIG_INFO. Work in progress;
397: - OpenBSD specific support is removed from sources;
398: - support for Mac OS X and Windows/Cygwin is added.

438: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
439: - in formatted file, string format returned a variable length string even if
440: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
441: a variable length string and 'CHARACTER*(n)' a fixed length string;

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

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

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

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

521: - DISP now locks stdout;
522: - rpliconv is added to replace standard iconv provided by operating system.
523: Indeed, conversion between different encodages requires transliteration
524: that is not offered by some iconv utility;
525: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
526: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

534: set);
535: - LOCALIZATION, UCASE and LCASE are added;

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

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

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

868: without this option !
869: - new garbage collector (and more efficient) is written;
870: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
871: not support real time signals, RPL/2 cannot use multitasking functions;

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

1074: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1075: versions of PROTECT and UNPROTECT that only deal with global variables
1076: (see RCL/SAVE);
1077: - variable management routines have been rewritten. The new ones are
1078: uncompatible with the old ones. Before these changes, a local variable
1079: was exported to a child subroutine, but cannot be modified into this
1080: child subroutine. Now, a local variable is accessible only in its subroutine;

1520: VISIT does not find a name in level 1;
1521: - configure.in script is modified to add a new test (--enable-debug
1522: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1523: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1524: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1525: 'MATRIX' { 2 2 3 } GETR;
1526: - LOGSCALE intrinsic is improved and now, it can be used as
1527: { "main" "auxiliary" X Y } LOGSCALE;
1528: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1529: same than AXES:
1530: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1531: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1532: { { -10 10 } "automatic" } SCALE.
1533: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1534: because it changes only the dimension of the screen. To have a logarithmic
1535: scale, you must use LOGSCALE intrinsic:
1536: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1537: screen on second scale;
1538: - { X X } autoscale and { Y Y } logscale are now invalid;
1539: - *D is added (depth multiplication, for 3D graphics);
1540: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1541: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1542: - a major bug is fixed in GETI instrinsic when it is used with a name
1543: that contains a matrix or a vector (bad upper bounds conditions in
1544: incrementation);
1545: - DISP intrinsic now uses the 33-th flag. When it is not set
1546: (default), a final carriage return is sent to the terminal;
1547: - AXES intrinsic only takes a list that can contains the keywork
1548: "main" or "auxiliary". Before this modification, this keyword was in
1549: the first stack level;
1550: - vim syntax file is upgraded;
1551: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1552: option;
1553: - LAST is now disabled in the main loop of INT intrinsic;
1554: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1555: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1556: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1557: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1558: in 0);
1559: - LAST is disabled in the main loop of DRAW intrinsic;
1560: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1561: evaluation of an equation, the system stack is returned corrupted to the
1562: sequencer;
1563: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1564: of a loop are not integer or real.
1565: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1566: - the compilation stage aborts with an error message when two definitions
1567: have the same name. To improve the compilation() subroutine, I have to
1568: add some tests in gestion_variables.c;
1569: - recherche_type() subroutine ad some other connex subroutines are improved.
1570: Now, some syntax errors about object are caught and do not perform sequencer
1571: hangup;
1572: - readline is upgraded (minor compilation bug with recent gcc);
1573: - Makefile.am's and configure.in scripts are improved.
1574: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1575: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1576: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1577: the boxwidth, 1 by default);
1578: - recherche_type() is rewritten to be faster;
1579: - gsl is upgraded (release 1.3);
1580: - ncurses is upgraded and patched (release 5.3);
1581: - recherche_instruction_suivante() is fixed (string research with included
1582: '"') and rewritten to be faster;
1583: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1584: segfault.
1585: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1593: - a minor bug is fixed in evaluation subroutine;
1594: - vim syntax file is improved;
1595: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1596: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1597: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1598: is a quick and dirty workaround...);
1599: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1600: - rplconvert is improved.
1601: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1617: Now, an expression such as 'A+' returns an error when it is analyzed;
1618: - VISIT intrinsic is added;
1619: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1620: normal mode.

1711: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1712: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1713:
1714: Newton:[~/rpl/rpl] > time make install
