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

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

148: RPL/2 integer type;
149: - WFSOCK is modified to handle unconnected sockets;
150: - REGEX is added;
151: - RESTART is added (execvp() on main RPL/2 process);

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

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

293: parent process was not interrupted if it is not group master process. To fix
294: this bug, SIGINJECT signal is not sent by child process but by control thread
295: in parent process;
296: - minor bug is fixed in data injection (POKE) that does not work as expected
297: when child process is protected by NRPROC.
298: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
299: - --enable-sysv-sems is added to configure script to use SystemV semaphores
300: functions instead of POSIX functions. This function is disabled or forced on
301: systems that does not provide correct POSIX or SysV semaphores subsystem;
302: - a dirty but not quick patch is written to workaround broken siginfo
303: structures. This patch has been successfully tested. It uses a segment of
304: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
305: (Unix PID);
306: - some OpenBSD's hacks are added;
307: - broken siginfo->si_pid field is now checked by configure script;

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

333: - BACKTRACE intrinsic is added;
334: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
335: when this structure is included in IFERR/THEN/END structure and when an error is
336: caught;
337: - major bug is fixed in analyse() subroutine. When evaluation() returned error
338: in a compiled program, analyse() caught this error twice and randomly aborted
339: with a segmentation error;
340: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
341: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
342: signals;
343: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
344: matrix.
345: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
346: - minor bug is fixed in evaluation() subroutine. With this patch, same program

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

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

390: information about shared variable was not copied to new processus structure;
391: - some little memory leaks are fixed in evaluation(), recherche_type() and
392: sequenceur(). They only occured when syntax error were caught;
393: - IMPLICIT causes execution error instead system error;
394: - Hurd support is improved but currently broken because Hurd does not support
395: SIG_INFO. Work in progress;
396: - OpenBSD specific support is removed from sources;
397: - support for Mac OS X and Windows/Cygwin is added.

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

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

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

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

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

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

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

532: - double free is fixed in liberation() (type SQL, only occurs when locale is
533: set);
534: - LOCALIZATION, UCASE and LCASE are added;

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

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

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

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

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

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

1075: (see RCL/SAVE);
1076: - variable management routines have been rewritten. The new ones are
1077: uncompatible with the old ones. Before these changes, a local variable

1519: VISIT does not find a name in level 1;
1520: - configure.in script is modified to add a new test (--enable-debug
1521: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1522: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1523: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1524: 'MATRIX' { 2 2 3 } GETR;
1525: - LOGSCALE intrinsic is improved and now, it can be used as
1526: { "main" "auxiliary" X Y } LOGSCALE;
1527: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1528: same than AXES:
1529: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1530: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1531: { { -10 10 } "automatic" } SCALE.
1532: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1533: because it changes only the dimension of the screen. To have a logarithmic
1534: scale, you must use LOGSCALE intrinsic:
1535: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1536: screen on second scale;
1537: - { X X } autoscale and { Y Y } logscale are now invalid;
1538: - *D is added (depth multiplication, for 3D graphics);
1539: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1540: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1541: - a major bug is fixed in GETI instrinsic when it is used with a name
1542: that contains a matrix or a vector (bad upper bounds conditions in
1543: incrementation);
1544: - DISP intrinsic now uses the 33-th flag. When it is not set
1545: (default), a final carriage return is sent to the terminal;
1546: - AXES intrinsic only takes a list that can contains the keywork
1547: "main" or "auxiliary". Before this modification, this keyword was in
1548: the first stack level;
1549: - vim syntax file is upgraded;
1550: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1551: option;
1552: - LAST is now disabled in the main loop of INT intrinsic;
1553: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1554: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1555: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1556: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1557: in 0);
1558: - LAST is disabled in the main loop of DRAW intrinsic;
1559: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1560: evaluation of an equation, the system stack is returned corrupted to the
1561: sequencer;
1562: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1563: of a loop are not integer or real.
1564: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1565: - the compilation stage aborts with an error message when two definitions
1566: have the same name. To improve the compilation() subroutine, I have to
1567: add some tests in gestion_variables.c;
1568: - recherche_type() subroutine ad some other connex subroutines are improved.
1569: Now, some syntax errors about object are caught and do not perform sequencer
1570: hangup;
1571: - readline is upgraded (minor compilation bug with recent gcc);
1572: - Makefile.am's and configure.in scripts are improved.
1573: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1574: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1575: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1576: the boxwidth, 1 by default);
1577: - recherche_type() is rewritten to be faster;
1578: - gsl is upgraded (release 1.3);
1579: - ncurses is upgraded and patched (release 5.3);
1580: - recherche_instruction_suivante() is fixed (string research with included
1581: '"') and rewritten to be faster;
1582: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1583: segfault.
1584: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1592: - a minor bug is fixed in evaluation subroutine;
1593: - vim syntax file is improved;
1594: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1595: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1596: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1597: is a quick and dirty workaround...);
1598: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1599: - rplconvert is improved.
1600: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1616: Now, an expression such as 'A+' returns an error when it is analyzed;
1617: - VISIT intrinsic is added;
1618: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in

1710: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1711: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1712:
1713: Newton:[~/rpl/rpl] > time make install
