41: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
42: - major bug is fixed in STD format (1E7 sq prints 1);
43: - major bug is fixed in READ intrinsic (socket). This bug was introduced
44: by a new feature in glibc.
45: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
46: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
47: "ALL" IMPLICIT when it runs in interactive mode;
48: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
49: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
50: to use SAVE to manipulate global variables;
51: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
52: subroutines;
53: - fix major memory access violation in evaluation subroutine. Only occurs
54: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
55: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
56: when X was a vector or a table.
57: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

85: - gnuplot is upgraded to 4.4.2 due to major bugs.
86: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
87: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
88: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
89: corruption. As internal memory management have been improved, a best fit
90: allocator like ptmalloc3 is not required anymore;
91: - gnuplot is upgraded to 4.4.1;
92: - deadlock is fixed in signal handlers: same mutex was used in standard
93: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
94: and signal handlers. A new signal handler specific mutex is added;
95: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
96: that has to be evaluated by ->NUM;
97: - rplfile build process is modify to be sure that rplfile is not modified
98: after rpl build stage (to be sure that rplfile checksum is not modified after

106: parent process was not interrupted if it is not group master process. To fix
107: this bug, SIGINJECT signal is not sent by child process but by control thread
108: in parent process;
109: - minor bug is fixed in data injection (POKE) that does not work as expected
110: when child process is protected by NRPROC.
111: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
112: - --enable-sysv-sems is added to configure script to use SystemV semaphores
113: functions instead of POSIX functions. This function is disabled or forced on
114: systems that does not provide correct POSIX or SysV semaphores subsystem;
115: - a dirty but not quick patch is written to workaround broken siginfo
116: structures. This patch has been successfully tested. It uses a segment of
117: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
118: (Unix PID);
119: - some OpenBSD's hacks are added;
120: - broken siginfo->si_pid field is now checked by configure script;
121: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

138: Level 0 and 1 variables adresses were swapped when a global variable masked
139: a name of RPL/2 routine;
140: - major bug is fixed in global variable creation subroutine. When a global
141: variable was created and when a local variable existed with the same name,
142: computed address of global variable was wrong;
143: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
144: is forced in front of all libraries.
145: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
146: - BACKTRACE intrinsic is added;
147: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
148: when this structure is included in IFERR/THEN/END structure and when an error is
149: caught;
150: - major bug is fixed in analyse() subroutine. When evaluation() returned error
151: in a compiled program, analyse() caught this error twice and randomly aborted
152: with a segmentation error;
153: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
154: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
155: signals;
156: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
157: matrix.

176: format in FCH (file descriptor) and SCK (socket descriptor);
177: - debug routines are improved;
178: - PROCID is added;
179: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
180: and to not use swap;
181: - major bug is fixed in sql support. SQL connections were closed in all chield
182: process;
183: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
184: discovered in Solaris thread safe allocators (libmalloc and libumem) that
185: are first fit class allocators. Solaris libmtmalloc works better and is
186: a best fit class allocator but its performance is poor than ptmalloc3
187: performance;
188: - major bug is fixed in ROW+ intrinsic (new row was not added where it
189: should);
190: - minor bugs are fixed in interruptions.c (semaphores values when error is
191: caught);
192: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
193: created by SPAWN;
194: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute

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

262: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
263: each execution (md5 and sha1 sums) to enhance security. If one of these tools
264: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
265: on a non recoverable system error;
266: - openssl and sqlite3 libraries are added;
267: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
268: variable indicates RPL/2 root directory. If it is not set, root path
269: is given by configure script (d_exec_path);

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

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

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

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

373: or thread number;
374: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
375: was called before a pending interruption5 (SIGFSTOP), signal handler uses
376: a freed semaphore and corrupts heap;
377: - CLRERR is added to erase previous errors;
378: - ERRN and ERRM return exception message and number;
379: - major bug is fixed in interruptions.c. All signal are now bufferised
380: when semaphore_liste_threads is null to avoid deadlock. This bug only
381: occured when STOP was sent to a dying thread or process (when this thread or
382: process was running retrait_thread());
383: - matrix rank is computed before matrix inversion;
384: - file locks are added to stdin and stdout. stderr is not locked because
385: all messages written by signal handlers are sent to stderr;

405: - SVL and SVD are added;
406: - COND and RANK are added;
407: - DIAG-> and ->DIAG are added;
408: - major bug is fixed in DET intrinsic. DET is rewritten to avoid usage of
409: eigenvalues. In a first time, matrix rank is estimated to force determinant

411: compute determinant;
412: - QR matrix decomposition is added;
413: - LQ matrix decomposition is added;
414: - Fortran90 files are rewritten to use Fortran2003 bind(C) statement and

417: -Wno-unused-parameter;
418: - all mathematical exceptions are now signaled by exceptions instead of
419: execution error;
420: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
421: can call twice CSTOP without RSTOP;
422: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
423: SMPHRTRYDECR, SMPHGETV).

425: - semaphore is added in interruptions.c to avoid segmentation fault when STOP
426: signal is sent to a dying thread. Some mutexes are replaced by semaphores too
427: to be used in signal handlers;
428: - major bug (memory corruption) is fixed in COL- intrinsic;
429: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
430: software interrupt was caught;
431: - rplpp man page is added.
432: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
433: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
434: process termination);
435: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
436: its parent);
437: - a mutex to protect fork() syscall is added;

460: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
461: process is killed;
462: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
463: know typeof() intrinsic function. This function is not standard but exists
464: under Sun Studio, gcc, and maybe some others compilers. If this function does
465: not exist on your compiler, you can change its definition by old one in
466: src/rpl.h;
467: - fflush() can now be interrupted by signal (SunOS);
468: - fflush(NULL) is called before all fork() occurrences;

487: is send from an external process;
488: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
489: deadlock when a huge amount of threads is launched);
490: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
491: arguments types are unsupported;
492: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

507: static variable that is shared by multiple threads;
508: - '->' intrinsic is improved. All object copies have been avoided;
509: - -n flag is added to catch HUP signal. stderr and stdout are redirected
510: to a file, stdin is redirected to /dev/null when control process is killed;
511: - a mutex is added to each object (before this modification,
512: RPL/2 used a global mutex and performances in multithreaded programs were very
513: poor.);

527: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
528: that all programs that worked with old SQL intrinsic can now work with
529: SQLQUERY. With all new programs, you can open a real connection to databases;
530: - NRPROC is added. This new intrinsic is used to catch error from child
531: process. Without NRPROC, any errors returned by child process cause
532: main process to abort;
533: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
534: starts a new process). There are no mutexes in RPL/2 because all spawned process
535: use specific context. Nevertheless, shared variables and associated mutexes
536: should be added;
537: - -D flag and DAEMONIZE intrinsic have been added;

676: - -f parameter is added when iconv is called;
677: - as old file program was bugged, a new option is added to configure script.
678: When configure is called with --disable-encoding-autodetection, make does not
679: try to detect source encoding. Please, do not use if RPL/2 can be built
680: without this option !
681: - new garbage collector (and more efficient) is written;
682: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
683: not support real time signals, RPL/2 cannot use multitasking functions;
684: - error returned by preprocessor are now catched by RPL/2;
685: - -p option is added. With this option, all scripts are compiled before
686: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
687: 40% faster;
688: - read and write operations in pipe() are rewritten to be sure that such
689: operations are atomic;

831: - external wrapper (rplplot) is written to force usage of gnuplot provided
832: by RPL/2 if it is built during build process. If this build does not exist,
833: it tries to launch regular gnuplot;
834: - gnuplot is added to source tree to avoid some trouble between preinstalled
835: gnuplot and release used by RPL/2. This addition to source tree is

1212: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1213: on Debian distribution, but since cpp is in the default path, RPL/2 works
1214: fine...);
1215: - NOT is not correctly formatted in formateur.c:
1216: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1217: with a NOTZ function !
1218: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1219: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1221: - RPL/2 is tested with efence and valgrind;
1222: - configure.in script is modified;
1223: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1303: - SCLS is added;
1304: - DRWS now uses COLS to draw 2D graphics;
1305: - PPAR and SPAR are written. SPAR returns a list that contains the
1306: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1307: statistical variable, or "DISABLED" if its type is not one of the type of
1308: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1309: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1310: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1311: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1312: disabled. Arguments of EXTERNAL are case sensitive because the external
1313: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1314: of known external functions but add the new list to the last. { "all" }
1315: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1316: external names of the known functions;
1317: - mkrplso.in is modified.
1318: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1319: - vim syntax file is upgraded;
1320: - a minor mistake is fixed in recherche_instruction_suivante();
1321: - some minor memory leaks are fixed in recherche_type() function. They only

1330: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1331: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1332: VISIT does not find a name in level 1;
1333: - configure.in script is modified to add a new test (--enable-debug
1334: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1335: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1336: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1337: 'MATRIX' { 2 2 3 } GETR;
1338: - LOGSCALE intrinsic is improved and now, it can be used as
1339: { "main" "auxiliary" X Y } LOGSCALE;
1340: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1341: same than AXES:
1342: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1343: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1344: { { -10 10 } "automatic" } SCALE.
1345: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1346: because it changes only the dimension of the screen. To have a logarithmic
1347: scale, you must use LOGSCALE intrinsic:
1348: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1349: screen on second scale;
1350: - { X X } autoscale and { Y Y } logscale are now invalid;
1351: - *D is added (depth multiplication, for 3D graphics);
1352: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1353: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1354: - a major bug is fixed in GETI instrinsic when it is used with a name
1355: that contains a matrix or a vector (bad upper bounds conditions in
1356: incrementation);
1357: - DISP intrinsic now uses the 33-th flag. When it is not set
1358: (default), a final carriage return is sent to the terminal;
1359: - AXES intrinsic only takes a list that can contains the keywork
1360: "main" or "auxiliary". Before this modification, this keyword was in
1361: the first stack level;
1362: - vim syntax file is upgraded;
1363: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1364: option;
1365: - LAST is now disabled in the main loop of INT intrinsic;
1366: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1367: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1368: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1369: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1370: in 0);
1371: - LAST is disabled in the main loop of DRAW intrinsic;
1372: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1373: evaluation of an equation, the system stack is returned corrupted to the
1374: sequencer;
1375: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1376: of a loop are not integer or real.
1377: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1378: - the compilation stage aborts with an error message when two definitions
1379: have the same name. To improve the compilation() subroutine, I have to
1380: add some tests in gestion_variables.c;
1381: - recherche_type() subroutine ad some other connex subroutines are improved.
1382: Now, some syntax errors about object are caught and do not perform sequencer
1383: hangup;
1384: - readline is upgraded (minor compilation bug with recent gcc);
1385: - Makefile.am's and configure.in scripts are improved.
1386: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1387: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1388: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1389: the boxwidth, 1 by default);
1390: - recherche_type() is rewritten to be faster;
1391: - gsl is upgraded (release 1.3);
1392: - ncurses is upgraded and patched (release 5.3);
1393: - recherche_instruction_suivante() is fixed (string research with included
1394: '"') and rewritten to be faster;

1396: segfault.
1397: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1405: - a minor bug is fixed in evaluation subroutine;
1406: - vim syntax file is improved;
1407: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1408: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1409: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1410: is a quick and dirty workaround...);
1411: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1412: - rplconvert is improved.

1522: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1523: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1524: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1525:
1526: Newton:[~/rpl/rpl] > time make install
1527: ...
1528: real 338m39.623s
1529: user 324m32.290s
1530: sys 10m47.380s
1531: Newton:[~/rpl/rpl] >
1532:
1533: I don't know if you will compile this language on old worstations, but
1534: it is usable ;-) ;
1535: - SYSEVAL is improved. An external program can be called without any shell.
