10: - libmtmalloc is now default Solaris allocator;
11: - ncurses is upgraded;
12: - regression introduced by 4.0.19 is fixed in signal management.

19: - gnuplot is upgraded to 4.4.2 due to major bugs.
20: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
21: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
22: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
23: corruption. As internal memory management have been improved, a best fit
24: allocator like ptmalloc3 is not required anymore;
25: - gnuplot is upgraded to 4.4.1;
26: - deadlock is fixed in signal handlers: same mutex was used in standard
27: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
28: and signal handlers. A new signal handler specific mutex is added;
29: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
30: that has to be evaluated by ->NUM;
31: - rplfile build process is modify to be sure that rplfile is not modified
32: after rpl build stage (to be sure that rplfile checksum is not modified after
33: rpl compilation);
34: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
35: modified to remove yacc code and renamed;

37: ABORT now works on eComStation;
38: - sqlite is upgraded to 3.7.2;
39: - bug is fixed in software interrupts. When both process have different PID,
40: parent process was not interrupted if it is not group master process. To fix
41: this bug, SIGINJECT signal is not sent by child process but by control thread
42: in parent process;
43: - minor bug is fixed in data injection (POKE) that does not work as expected
44: when child process is protected by NRPROC.
45: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
46: - --enable-sysv-sems is added to configure script to use SystemV semaphores
47: functions instead of POSIX functions. This function is disabled or forced on
48: systems that does not provide correct POSIX or SysV semaphores subsystem;
49: - a dirty but not quick patch is written to workaround broken siginfo
50: structures. This patch has been successfully tested. It uses a segment of
51: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
52: (Unix PID);
53: - some OpenBSD's hacks are added;
54: - broken siginfo->si_pid field is now checked by configure script;
55: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

69: - sqlite is upgraded to 3.7.0.1;
70: - units is upgraded to 1.88;
71: - another major bug is fixed in the same variable creation subroutine.
72: Level 0 and 1 variables adresses were swapped when a global variable masked
73: a name of RPL/2 routine;
74: - major bug is fixed in global variable creation subroutine. When a global
75: variable was created and when a local variable existed with the same name,
76: computed address of global variable was wrong;
77: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
78: is forced in front of all libraries.
79: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
80: - BACKTRACE intrinsic is added;
81: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
82: when this structure is included in IFERR/THEN/END structure and when an error is
83: caught;
84: - major bug is fixed in analyse() subroutine. When evaluation() returned error
85: in a compiled program, analyse() caught this error twice and randomly aborted
86: with a segmentation error;
87: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
88: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
89: signals;
90: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
91: matrix.
92: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

112: - PROCID is added;
113: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
114: and to not use swap;
115: - major bug is fixed in sql support. SQL connections were closed in all chield
116: process;
117: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
118: discovered in Solaris thread safe allocators (libmalloc and libumem) that
119: are first fit class allocators. Solaris libmtmalloc works better and is
120: a best fit class allocator but its performance is poor than ptmalloc3
121: performance;
122: - major bug is fixed in ROW+ intrinsic (new row was not added where it
123: should);
124: - minor bugs are fixed in interruptions.c (semaphores values when error is
125: caught);
126: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
127: created by SPAWN;
128: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
129: ATEXIT. If it receives SIGFABORT, it does not;
130: - ONEXIT is renamed in ATEXIT;
131: - ONEXIT new intrinsic is added.

137: information about shared variable was not copied to new processus structure;
138: - some little memory leaks are fixed in evaluation(), recherche_type() and
139: sequenceur(). They only occured when syntax error were caught;
140: - IMPLICIT causes execution error instead system error;
141: - Hurd support is improved but currently broken because Hurd does not support
142: SIG_INFO. Work in progress;
143: - OpenBSD specific support is removed from sources;
144: - support for Mac OS X and Windows/Cygwin is added.
145: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

184: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
185: - in formatted file, string format returned a variable length string even if
186: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
187: a variable length string and 'CHARACTER*(n)' a fixed length string;
188: - keyed access files support is added. Currently, only formatted files are
189: supported;
190: - direct access files support is added. Currenlty, these files can only be used
191: in formatted mode;
192: - virtual variables are now writte in UTF-8 and all special characters
193: in string are escaped;
194: - all formatted files are now converted into UTF-8;
195: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
196: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
197: each execution (md5 and sha1 sums) to enhance security. If one of these tools
198: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
199: on a non recoverable system error;
200: - openssl and sqlite3 libraries are added;
201: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
202: variable indicates RPL/2 root directory. If it is not set, root path
203: is given by configure script (d_exec_path);
204: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

237: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
238: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
239: signals sent to main process were not caught because DAEMON did not replace
240: old pid by new one;
241: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
242: evaluation when an error is reported from a subroutine in another subroutine.
243: For example, error was not caught in following program when it is executed with
244: -p option :
245: TEST << iferr TEST2 then end >>
246: TEST2 << 0 inv >>
247: - major bug is fixed in variable management. Some local variables were
248: seen as global ones;

250: script file contains a multibyte character;
251: - IN intrinsic is added;
252: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
253: returned false ;

261: - major bug is fixed in -A command line option (NULL character is missing);
262: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
263: made by blocks (1024 bytes). When an incomplete multibyte sequence is
264: encountered at end of block, subroutine aborts with an execution error;
265: - major bug is fixed in OPEN (TCP/IPv4 sockets).
266: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
267: - DISP now locks stdout;
268: - rpliconv is added to replace standard iconv provided by operating system.
269: Indeed, conversion between different encodages requires transliteration
270: that is not offered by some iconv utility;
271: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
272: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
273: not be found), SYSEVAL enters in a dead lock;
274: - fprintf is replaced by some functions that allow transliterations between
275: locales;
276: - '"' can now be used in strings ("\"");
277: - iconv is called with -c in preprocessor stage. It is done to write
278: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
279: - double free is fixed in liberation() (type SQL, only occurs when locale is
280: set);
281: - LOCALIZATION, UCASE and LCASE are added;

283: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
284: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
285: used in onLoading from shared library, USE was pushed on stack as algebraic
286: expression;
287: - libiconv is upgraded to 1.13.1;
288: - gnuplot is upgraded to 4.2.6;
289: - gsl is upgraded to 1.13.

291: - pipe() is overwritten by a macro to avoid a system error. Communication
292: between process are done with pipes and these pipes are managed by a
293: specific asynchrone thread. If a script try to create more threads than
294: management thread can destroy, you can quickly achieve maximum number of
295: opened files and pipe() shall return a system error. This macro tries to create
296: pipes. If pipe() function returns an error, macro waits and retries. If
297: number of retries is greater than a hardcoded value, macro returns an error;
298: - major bug (deadlock) is fixed in process and thread management. I hope
299: this bug shall be the last one;
300: - major bug is fixed in DET intrinsic (determinant was computed without LU
301: diagonalization);

307: or thread number;
308: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
309: was called before a pending interruption5 (SIGFSTOP), signal handler uses
310: a freed semaphore and corrupts heap;
311: - CLRERR is added to erase previous errors;
312: - ERRN and ERRM return exception message and number;
313: - major bug is fixed in interruptions.c. All signal are now bufferised
314: when semaphore_liste_threads is null to avoid deadlock. This bug only
315: occured when STOP was sent to a dying thread or process (when this thread or
316: process was running retrait_thread());
317: - matrix rank is computed before matrix inversion;
318: - file locks are added to stdin and stdout. stderr is not locked because
319: all messages written by signal handlers are sent to stderr;

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

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

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

462: that all programs that worked with old SQL intrinsic can now work with
463: SQLQUERY. With all new programs, you can open a real connection to databases;
464: - NRPROC is added. This new intrinsic is used to catch error from child
465: process. Without NRPROC, any errors returned by child process cause
466: main process to abort;
467: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
468: starts a new process). There are no mutexes in RPL/2 because all spawned process
469: use specific context. Nevertheless, shared variables and associated mutexes
470: should be added;

767: it tries to launch regular gnuplot;
768: - gnuplot is added to source tree to avoid some trouble between preinstalled
769: gnuplot and release used by RPL/2. This addition to source tree is
770: required by some incompatibility between gnuplot releases;
771: - Lapack is upgraded to 3.1.1 release;
772: - GSL is upgraded to 1.9 revision;

1187: 1: x;
1188: - ->Q intrinsic is added;
1189: - major bug is fixed in C->R intrinsic;
1190: - ROW+ and ROW- are added and tested;
1191: - COL+ and COL- are added and tested. Syntax:
1192: 3: matrix
1193: 2: integer (number of column to be inserted)
1194: 1: column matrix to be inserted;
1195: - major bug was discovered in interface_gnuplot(). It only occurs when

1204: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1205: - SLICESCALE intrinsic is added. Its syntax is
1206: { "automatic" nb_of_levels }
1207: { "discrete" l1 l2 l3 ... }
1208: { "incremental" start incr }
1209: { "incremental" start incr end }
1210: { "automatic" } (default);
1211: - a minor bug (in last stack) is fixed in AXES intrinsic
1212: - flag 52 is used to automatically update graphics;
1213: - man pages are updated;
1214: - evaluation() is modified to perform evaluation of expressions that contain
1215: '=';
1216: - a minor bug is fixed in AXES intrinsic;
1217: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1218: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1219: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1220: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1221: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1228: - '=' is added and tested;
1229: - XCOL and YCOL are added;
1230: - a minor bug in analyse_syntaxique() is fixed;
1231: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1232: structure. ELSE is modified to return an error when ELSE appears in
1233: an ELSE/END structure;
1234: - a major bug is fixed in CYCLE;

1236: sequencer continues after the end of this loop;
1237: - SCLS is added;
1238: - DRWS now uses COLS to draw 2D graphics;
1239: - PPAR and SPAR are written. SPAR returns a list that contains the
1240: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1241: statistical variable, or "DISABLED" if its type is not one of the type of
1242: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1243: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1244: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1245: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1246: disabled. Arguments of EXTERNAL are case sensitive because the external
1247: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1248: of known external functions but add the new list to the last. { "all" }
1249: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1250: external names of the known functions;
1251: - mkrplso.in is modified.
1252: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1253: - vim syntax file is upgraded;
1254: - a minor mistake is fixed in recherche_instruction_suivante();
1255: - some minor memory leaks are fixed in recherche_type() function. They only
1256: occurs when a syntax error is detected;
1257: - #error and #warning preprocessor macros are added;
1258: - INCR and DECR are written (with integer or variable argument);
1259: - CSWP and RSWP are added and tested;
1260: - a minor bug is fixed in analyse.c;
1261: - DEBIAN/control is added to build debian package;
1262: - SCALE is fixed and improved ("automatic" keyword);
1263: - PUTC and PUTR new intrinsics are added.
1264: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1265: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1266: VISIT does not find a name in level 1;
1267: - configure.in script is modified to add a new test (--enable-debug
1268: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1269: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1270: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1271: 'MATRIX' { 2 2 3 } GETR;
1272: - LOGSCALE intrinsic is improved and now, it can be used as
1273: { "main" "auxiliary" X Y } LOGSCALE;
1274: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1275: same than AXES:
1276: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1277: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1278: { { -10 10 } "automatic" } SCALE.
1279: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1280: because it changes only the dimension of the screen. To have a logarithmic
1281: scale, you must use LOGSCALE intrinsic:
1282: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1283: screen on second scale;
1284: - { X X } autoscale and { Y Y } logscale are now invalid;
1285: - *D is added (depth multiplication, for 3D graphics);
1286: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1287: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1288: - a major bug is fixed in GETI instrinsic when it is used with a name
1289: that contains a matrix or a vector (bad upper bounds conditions in
1290: incrementation);
1291: - DISP intrinsic now uses the 33-th flag. When it is not set
1292: (default), a final carriage return is sent to the terminal;
1293: - AXES intrinsic only takes a list that can contains the keywork
1294: "main" or "auxiliary". Before this modification, this keyword was in
1295: the first stack level;
1296: - vim syntax file is upgraded;
1297: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1298: option;
1299: - LAST is now disabled in the main loop of INT intrinsic;
1300: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1301: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1302: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1303: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1304: in 0);
1305: - LAST is disabled in the main loop of DRAW intrinsic;
1306: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1307: evaluation of an equation, the system stack is returned corrupted to the
1308: sequencer;
1309: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1310: of a loop are not integer or real.
1311: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1312: - the compilation stage aborts with an error message when two definitions
1313: have the same name. To improve the compilation() subroutine, I have to
1314: add some tests in gestion_variables.c;
1315: - recherche_type() subroutine ad some other connex subroutines are improved.
1316: Now, some syntax errors about object are caught and do not perform sequencer
1317: hangup;
1318: - readline is upgraded (minor compilation bug with recent gcc);
1319: - Makefile.am's and configure.in scripts are improved.
1320: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1321: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1322: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1323: the boxwidth, 1 by default);
1324: - recherche_type() is rewritten to be faster;
1325: - gsl is upgraded (release 1.3);
1326: - ncurses is upgraded and patched (release 5.3);
1327: - recherche_instruction_suivante() is fixed (string research with included
1328: '"') and rewritten to be faster;
1329: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1330: segfault.
1331: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1339: - a minor bug is fixed in evaluation subroutine;
1340: - vim syntax file is improved;
1341: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1342: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1343: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1344: is a quick and dirty workaround...);
1345: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1346: - rplconvert is improved.
1347: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1363: Now, an expression such as 'A+' returns an error when it is analyzed;
1364: - VISIT intrinsic is added;
1365: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1366: normal mode.

1454: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1455: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1456: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1457: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1458: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1459:
1460: Newton:[~/rpl/rpl] > time make install
1461: ...
1462: real 338m39.623s
1463: user 324m32.290s
1464: sys 10m47.380s
1465: Newton:[~/rpl/rpl] >
1466:
1467: I don't know if you will compile this language on old worstations, but
1468: it is usable ;-) ;
1469: - SYSEVAL is improved. An external program can be called without any shell.
