57: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
58: - major bug is fixed in STD format (1E7 sq prints 1);
59: - major bug is fixed in READ intrinsic (socket). This bug was introduced
60: by a new feature in glibc.
61: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
62: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
63: "ALL" IMPLICIT when it runs in interactive mode;
64: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
65: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
66: to use SAVE to manipulate global variables;
67: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
68: subroutines;
69: - fix major memory access violation in evaluation subroutine. Only occurs
70: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
71: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
72: when X was a vector or a table.
73: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

102: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
103: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
104: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
105: corruption. As internal memory management have been improved, a best fit
106: allocator like ptmalloc3 is not required anymore;
107: - gnuplot is upgraded to 4.4.1;
108: - deadlock is fixed in signal handlers: same mutex was used in standard
109: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
110: and signal handlers. A new signal handler specific mutex is added;
111: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
112: that has to be evaluated by ->NUM;
113: - rplfile build process is modify to be sure that rplfile is not modified
114: after rpl build stage (to be sure that rplfile checksum is not modified after

122: parent process was not interrupted if it is not group master process. To fix
123: this bug, SIGINJECT signal is not sent by child process but by control thread
124: in parent process;
125: - minor bug is fixed in data injection (POKE) that does not work as expected
126: when child process is protected by NRPROC.
127: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
128: - --enable-sysv-sems is added to configure script to use SystemV semaphores
129: functions instead of POSIX functions. This function is disabled or forced on
130: systems that does not provide correct POSIX or SysV semaphores subsystem;
131: - a dirty but not quick patch is written to workaround broken siginfo
132: structures. This patch has been successfully tested. It uses a segment of
133: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
134: (Unix PID);
135: - some OpenBSD's hacks are added;
136: - broken siginfo->si_pid field is now checked by configure script;

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

192: format in FCH (file descriptor) and SCK (socket descriptor);
193: - debug routines are improved;
194: - PROCID is added;
195: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
196: and to not use swap;
197: - major bug is fixed in sql support. SQL connections were closed in all chield
198: process;
199: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
200: discovered in Solaris thread safe allocators (libmalloc and libumem) that
201: are first fit class allocators. Solaris libmtmalloc works better and is
202: a best fit class allocator but its performance is poor than ptmalloc3
203: performance;
204: - major bug is fixed in ROW+ intrinsic (new row was not added where it
205: should);
206: - minor bugs are fixed in interruptions.c (semaphores values when error is
207: caught);
208: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
209: created by SPAWN;

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

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

320: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
321: signals sent to main process were not caught because DAEMON did not replace
322: old pid by new one;
323: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression

351: Indeed, conversion between different encodages requires transliteration
352: that is not offered by some iconv utility;
353: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
354: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

357: locales;
358: - '"' can now be used in strings ("\"");
359: - iconv is called with -c in preprocessor stage. It is done to write

373: - pipe() is overwritten by a macro to avoid a system error. Communication
374: between process are done with pipes and these pipes are managed by a
375: specific asynchrone thread. If a script try to create more threads than
376: management thread can destroy, you can quickly achieve maximum number of
377: opened files and pipe() shall return a system error. This macro tries to create
378: pipes. If pipe() function returns an error, macro waits and retries. If
379: number of retries is greater than a hardcoded value, macro returns an error;
380: - major bug (deadlock) is fixed in process and thread management. I hope

387: - some bugfixes are added in process management;
388: - all process management is rewritten to avoid usage of defunct process
389: or thread number;

392: a freed semaphore and corrupts heap;
393: - CLRERR is added to erase previous errors;
394: - ERRN and ERRM return exception message and number;
395: - major bug is fixed in interruptions.c. All signal are now bufferised
396: when semaphore_liste_threads is null to avoid deadlock. This bug only
397: occured when STOP was sent to a dying thread or process (when this thread or
398: process was running retrait_thread());
399: - matrix rank is computed before matrix inversion;
400: - file locks are added to stdin and stdout. stderr is not locked because
401: all messages written by signal handlers are sent to stderr;
402: - configure.in script is modified to test gcc version and avoid a bug in
403: gcc older than 4.4;
404: - some benchmarks have been done :

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

505: deadlock when a huge amount of threads is launched);
506: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
507: arguments types are unsupported;
508: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

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

543: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
544: that all programs that worked with old SQL intrinsic can now work with
545: SQLQUERY. With all new programs, you can open a real connection to databases;
546: - NRPROC is added. This new intrinsic is used to catch error from child
547: process. Without NRPROC, any errors returned by child process cause
548: main process to abort;
549: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
550: starts a new process). There are no mutexes in RPL/2 because all spawned process
551: use specific context. Nevertheless, shared variables and associated mutexes
552: should be added;

692: - -f parameter is added when iconv is called;
693: - as old file program was bugged, a new option is added to configure script.
694: When configure is called with --disable-encoding-autodetection, make does not
695: try to detect source encoding. Please, do not use if RPL/2 can be built
696: without this option !
697: - new garbage collector (and more efficient) is written;

847: - external wrapper (rplplot) is written to force usage of gnuplot provided
848: by RPL/2 if it is built during build process. If this build does not exist,
849: it tries to launch regular gnuplot;
850: - gnuplot is added to source tree to avoid some trouble between preinstalled
851: gnuplot and release used by RPL/2. This addition to source tree is
852: required by some incompatibility between gnuplot releases;
853: - Lapack is upgraded to 3.1.1 release;
854: - GSL is upgraded to 1.9 revision;

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

1230: fine...);
1231: - NOT is not correctly formatted in formateur.c:
1232: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1233: with a NOTZ function !
1234: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1235: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1237: - RPL/2 is tested with efence and valgrind;
1238: - configure.in script is modified;
1239: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1300: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1301: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1302: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1319: - SCLS is added;
1320: - DRWS now uses COLS to draw 2D graphics;
1321: - PPAR and SPAR are written. SPAR returns a list that contains the
1322: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1323: statistical variable, or "DISABLED" if its type is not one of the type of
1324: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1325: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1326: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1327: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1328: disabled. Arguments of EXTERNAL are case sensitive because the external
1329: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1330: of known external functions but add the new list to the last. { "all" }
1331: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1332: external names of the known functions;
1333: - mkrplso.in is modified.
1334: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1335: - vim syntax file is upgraded;
1336: - a minor mistake is fixed in recherche_instruction_suivante();
1337: - some minor memory leaks are fixed in recherche_type() function. They only

1346: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1347: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1348: VISIT does not find a name in level 1;
1349: - configure.in script is modified to add a new test (--enable-debug
1350: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1351: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1352: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1353: 'MATRIX' { 2 2 3 } GETR;
1354: - LOGSCALE intrinsic is improved and now, it can be used as
1355: { "main" "auxiliary" X Y } LOGSCALE;
1356: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1357: same than AXES:
1358: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1359: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1360: { { -10 10 } "automatic" } SCALE.
1361: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1362: because it changes only the dimension of the screen. To have a logarithmic
1363: scale, you must use LOGSCALE intrinsic:
1364: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1365: screen on second scale;
1366: - { X X } autoscale and { Y Y } logscale are now invalid;
1367: - *D is added (depth multiplication, for 3D graphics);
1368: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1369: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1370: - a major bug is fixed in GETI instrinsic when it is used with a name
1371: that contains a matrix or a vector (bad upper bounds conditions in
1372: incrementation);
1373: - DISP intrinsic now uses the 33-th flag. When it is not set
1374: (default), a final carriage return is sent to the terminal;
1375: - AXES intrinsic only takes a list that can contains the keywork
1376: "main" or "auxiliary". Before this modification, this keyword was in
1377: the first stack level;
1378: - vim syntax file is upgraded;
1379: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1380: option;
1381: - LAST is now disabled in the main loop of INT intrinsic;
1382: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1383: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1384: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1385: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1386: in 0);
1387: - LAST is disabled in the main loop of DRAW intrinsic;
1388: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1389: evaluation of an equation, the system stack is returned corrupted to the
1390: sequencer;
1391: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1392: of a loop are not integer or real.
1393: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1394: - the compilation stage aborts with an error message when two definitions
1395: have the same name. To improve the compilation() subroutine, I have to
1396: add some tests in gestion_variables.c;
1397: - recherche_type() subroutine ad some other connex subroutines are improved.
1398: Now, some syntax errors about object are caught and do not perform sequencer
1399: hangup;
1400: - readline is upgraded (minor compilation bug with recent gcc);
1401: - Makefile.am's and configure.in scripts are improved.
1402: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1403: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1404: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1405: the boxwidth, 1 by default);
1406: - recherche_type() is rewritten to be faster;
1407: - gsl is upgraded (release 1.3);
1408: - ncurses is upgraded and patched (release 5.3);
1409: - recherche_instruction_suivante() is fixed (string research with included
1410: '"') and rewritten to be faster;
1411: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1412: segfault.

1422: - vim syntax file is improved;
1423: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1424: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1425: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1426: is a quick and dirty workaround...);
1427: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1428: - rplconvert is improved.

1539: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1540: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1541:
1542: Newton:[~/rpl/rpl] > time make install
1543: ...
1544: real 338m39.623s
1545: user 324m32.290s
