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

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

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

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

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

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

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

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

341: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
342: - DISP now locks stdout;
343: - rpliconv is added to replace standard iconv provided by operating system.
344: Indeed, conversion between different encodages requires transliteration
345: that is not offered by some iconv utility;
346: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
347: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

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

441: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
442: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
443: process termination);
444: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
445: its parent);
446: - a mutex to protect fork() syscall is added;

469: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
470: process is killed;
471: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
472: know typeof() intrinsic function. This function is not standard but exists
473: under Sun Studio, gcc, and maybe some others compilers. If this function does
474: not exist on your compiler, you can change its definition by old one in
475: src/rpl.h;

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

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

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

686: - as old file program was bugged, a new option is added to configure script.
687: When configure is called with --disable-encoding-autodetection, make does not
688: try to detect source encoding. Please, do not use if RPL/2 can be built
689: without this option !
690: - new garbage collector (and more efficient) is written;

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

1223: fine...);
1224: - NOT is not correctly formatted in formateur.c:
1225: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1226: with a NOTZ function !
1227: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1228: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1230: - RPL/2 is tested with efence and valgrind;
1231: - configure.in script is modified;
1232: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1293: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1294: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1295: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1312: - SCLS is added;
1313: - DRWS now uses COLS to draw 2D graphics;
1314: - PPAR and SPAR are written. SPAR returns a list that contains the
1315: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1316: statistical variable, or "DISABLED" if its type is not one of the type of
1317: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1318: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1319: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1320: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1321: disabled. Arguments of EXTERNAL are case sensitive because the external
1322: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1323: of known external functions but add the new list to the last. { "all" }
1324: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1325: external names of the known functions;
1326: - mkrplso.in is modified.
1327: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1328: - vim syntax file is upgraded;
1329: - a minor mistake is fixed in recherche_instruction_suivante();

1339: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1340: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1341: VISIT does not find a name in level 1;
1342: - configure.in script is modified to add a new test (--enable-debug
1343: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1344: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1345: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1346: 'MATRIX' { 2 2 3 } GETR;
1347: - LOGSCALE intrinsic is improved and now, it can be used as
1348: { "main" "auxiliary" X Y } LOGSCALE;
1349: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1350: same than AXES:
1351: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1352: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1353: { { -10 10 } "automatic" } SCALE.
1354: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1355: because it changes only the dimension of the screen. To have a logarithmic
1356: scale, you must use LOGSCALE intrinsic:
1357: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1358: screen on second scale;
1359: - { X X } autoscale and { Y Y } logscale are now invalid;
1360: - *D is added (depth multiplication, for 3D graphics);
1361: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1362: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1363: - a major bug is fixed in GETI instrinsic when it is used with a name
1364: that contains a matrix or a vector (bad upper bounds conditions in
1365: incrementation);
1366: - DISP intrinsic now uses the 33-th flag. When it is not set
1367: (default), a final carriage return is sent to the terminal;
1368: - AXES intrinsic only takes a list that can contains the keywork
1369: "main" or "auxiliary". Before this modification, this keyword was in
1370: the first stack level;
1371: - vim syntax file is upgraded;
1372: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1373: option;
1374: - LAST is now disabled in the main loop of INT intrinsic;
1375: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1376: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1377: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1378: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1379: in 0);
1380: - LAST is disabled in the main loop of DRAW intrinsic;
1381: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1382: evaluation of an equation, the system stack is returned corrupted to the
1383: sequencer;
1384: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1385: of a loop are not integer or real.
1386: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1387: - the compilation stage aborts with an error message when two definitions
1388: have the same name. To improve the compilation() subroutine, I have to
1389: add some tests in gestion_variables.c;
1390: - recherche_type() subroutine ad some other connex subroutines are improved.
1391: Now, some syntax errors about object are caught and do not perform sequencer
1392: hangup;
1393: - readline is upgraded (minor compilation bug with recent gcc);
1394: - Makefile.am's and configure.in scripts are improved.
1395: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1396: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1397: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1398: the boxwidth, 1 by default);
1399: - recherche_type() is rewritten to be faster;
1400: - gsl is upgraded (release 1.3);
1401: - ncurses is upgraded and patched (release 5.3);
1402: - recherche_instruction_suivante() is fixed (string research with included
1403: '"') and rewritten to be faster;

1417: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1418: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1419: is a quick and dirty workaround...);
1420: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1421: - rplconvert is improved.

1503: deleted too!;
1504: - configure script is improved (and it seems to be good ;-) );
1505: - An --disable-experimental flag is added to the configure script. Thus, even
1506: if you compile a beta release, you can compile a stable RPL/2;
1507: - new syntax and ftplugin written for vim 6.0.

1531: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1532: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1533: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1534:
1535: Newton:[~/rpl/rpl] > time make install
1536: ...
1537: real 338m39.623s
1538: user 324m32.290s
1539: sys 10m47.380s
1540: Newton:[~/rpl/rpl] >
1541:
1542: I don't know if you will compile this language on old worstations, but
1543: it is usable ;-) ;
1544: - SYSEVAL is improved. An external program can be called without any shell.
