1: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
2: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
3: "ALL" IMPLICIT when it runs in interactive mode;
4: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
5: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
6: to use SAVE to manipulate global variables;
7: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
8: subroutines;
9: - fix major memory access violation in evaluation subroutine. Only occurs
10: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
11: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
12: when X was a vector or a table.
13: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

36: segmentation fault;
37: - sqlite is upgraded to 3.7.4;
38: - OpenSSL is upgraded to 1.0.0c;
39: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);

41: - gnuplot is upgraded to 4.4.2 due to major bugs.
42: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
43: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
44: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
45: corruption. As internal memory management have been improved, a best fit
46: allocator like ptmalloc3 is not required anymore;
47: - gnuplot is upgraded to 4.4.1;
48: - deadlock is fixed in signal handlers: same mutex was used in standard
49: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
50: and signal handlers. A new signal handler specific mutex is added;
51: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
52: that has to be evaluated by ->NUM;
53: - rplfile build process is modify to be sure that rplfile is not modified
54: after rpl build stage (to be sure that rplfile checksum is not modified after
55: rpl compilation);

59: ABORT now works on eComStation;
60: - sqlite is upgraded to 3.7.2;
61: - bug is fixed in software interrupts. When both process have different PID,
62: parent process was not interrupted if it is not group master process. To fix
63: this bug, SIGINJECT signal is not sent by child process but by control thread
64: in parent process;
65: - minor bug is fixed in data injection (POKE) that does not work as expected
66: when child process is protected by NRPROC.
67: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
68: - --enable-sysv-sems is added to configure script to use SystemV semaphores
69: functions instead of POSIX functions. This function is disabled or forced on
70: systems that does not provide correct POSIX or SysV semaphores subsystem;
71: - a dirty but not quick patch is written to workaround broken siginfo
72: structures. This patch has been successfully tested. It uses a segment of
73: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
74: (Unix PID);
75: - some OpenBSD's hacks are added;
76: - broken siginfo->si_pid field is now checked by configure script;
77: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
78: - random generator is cloned by SPAWN;

94: Level 0 and 1 variables adresses were swapped when a global variable masked
95: a name of RPL/2 routine;
96: - major bug is fixed in global variable creation subroutine. When a global
97: variable was created and when a local variable existed with the same name,
98: computed address of global variable was wrong;
99: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
100: is forced in front of all libraries.
101: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
102: - BACKTRACE intrinsic is added;
103: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
104: when this structure is included in IFERR/THEN/END structure and when an error is
105: caught;
106: - major bug is fixed in analyse() subroutine. When evaluation() returned error
107: in a compiled program, analyse() caught this error twice and randomly aborted
108: with a segmentation error;
109: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
110: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
111: signals;
112: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
113: matrix.
114: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

134: - PROCID is added;
135: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
136: and to not use swap;
137: - major bug is fixed in sql support. SQL connections were closed in all chield
138: process;
139: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
140: discovered in Solaris thread safe allocators (libmalloc and libumem) that
141: are first fit class allocators. Solaris libmtmalloc works better and is
142: a best fit class allocator but its performance is poor than ptmalloc3
143: performance;
144: - major bug is fixed in ROW+ intrinsic (new row was not added where it
145: should);
146: - minor bugs are fixed in interruptions.c (semaphores values when error is
147: caught);
148: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
149: created by SPAWN;
150: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
151: ATEXIT. If it receives SIGFABORT, it does not;
152: - ONEXIT is renamed in ATEXIT;
153: - ONEXIT new intrinsic is added.

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

206: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
207: - in formatted file, string format returned a variable length string even if
208: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
209: a variable length string and 'CHARACTER*(n)' a fixed length string;
210: - keyed access files support is added. Currently, only formatted files are
211: supported;
212: - direct access files support is added. Currenlty, these files can only be used
213: in formatted mode;
214: - virtual variables are now writte in UTF-8 and all special characters
215: in string are escaped;
216: - all formatted files are now converted into UTF-8;
217: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
218: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
219: each execution (md5 and sha1 sums) to enhance security. If one of these tools
220: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
221: on a non recoverable system error;
222: - openssl and sqlite3 libraries are added;
223: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
224: variable indicates RPL/2 root directory. If it is not set, root path
225: is given by configure script (d_exec_path);
226: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

259: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
260: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
261: signals sent to main process were not caught because DAEMON did not replace
262: old pid by new one;
263: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
264: evaluation when an error is reported from a subroutine in another subroutine.
265: For example, error was not caught in following program when it is executed with
266: -p option :
267: TEST << iferr TEST2 then end >>
268: TEST2 << 0 inv >>
269: - major bug is fixed in variable management. Some local variables were
270: seen as global ones;
271: - major bug is fixed in rplcore. Rplcore entered in dead lock when
272: script file contains a multibyte character;
273: - IN intrinsic is added;
274: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
275: returned false ;

283: - major bug is fixed in -A command line option (NULL character is missing);
284: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
285: made by blocks (1024 bytes). When an incomplete multibyte sequence is
286: encountered at end of block, subroutine aborts with an execution error;
287: - major bug is fixed in OPEN (TCP/IPv4 sockets).
288: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
289: - DISP now locks stdout;
290: - rpliconv is added to replace standard iconv provided by operating system.
291: Indeed, conversion between different encodages requires transliteration
292: that is not offered by some iconv utility;
293: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
294: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

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

332: a freed semaphore and corrupts heap;
333: - CLRERR is added to erase previous errors;
334: - ERRN and ERRM return exception message and number;
335: - major bug is fixed in interruptions.c. All signal are now bufferised

416: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
417: process is killed;
418: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
419: know typeof() intrinsic function. This function is not standard but exists

485: SQLQUERY. With all new programs, you can open a real connection to databases;
486: - NRPROC is added. This new intrinsic is used to catch error from child
487: process. Without NRPROC, any errors returned by child process cause
488: main process to abort;
489: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
490: starts a new process). There are no mutexes in RPL/2 because all spawned process

789: it tries to launch regular gnuplot;
790: - gnuplot is added to source tree to avoid some trouble between preinstalled
791: gnuplot and release used by RPL/2. This addition to source tree is

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

1167: (less parenthesis);
1168: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1169: on Debian distribution, but since cpp is in the default path, RPL/2 works
1170: fine...);
1171: - NOT is not correctly formatted in formateur.c:
1172: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1173: with a NOTZ function !
1174: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1175: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1176: if the main loop is in a program;
1177: - RPL/2 is tested with efence and valgrind;
1178: - configure.in script is modified;
1179: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1180: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1181: another gcc bug...
1182: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)
1183: - EXIT is fixed. Now, it is possible to use EXIT in an expression when the
1184: main loop is in a program;

1215: 2: integer (number of column to be inserted)
1216: 1: column matrix to be inserted;
1217: - major bug was discovered in interface_gnuplot(). It only occurs when

1226: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1227: - SLICESCALE intrinsic is added. Its syntax is
1228: { "automatic" nb_of_levels }
1229: { "discrete" l1 l2 l3 ... }
1230: { "incremental" start incr }
1231: { "incremental" start incr end }
1232: { "automatic" } (default);
1233: - a minor bug (in last stack) is fixed in AXES intrinsic
1234: - flag 52 is used to automatically update graphics;
1235: - man pages are updated;
1236: - evaluation() is modified to perform evaluation of expressions that contain
1237: '=';
1238: - a minor bug is fixed in AXES intrinsic;
1239: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1240: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1241: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1242: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1243: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1259: - SCLS is added;
1260: - DRWS now uses COLS to draw 2D graphics;
1261: - PPAR and SPAR are written. SPAR returns a list that contains the
1262: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1263: statistical variable, or "DISABLED" if its type is not one of the type of
1264: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1265: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1266: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1267: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1268: disabled. Arguments of EXTERNAL are case sensitive because the external
1269: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1270: of known external functions but add the new list to the last. { "all" }
1271: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1272: external names of the known functions;
1273: - mkrplso.in is modified.
1274: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1275: - vim syntax file is upgraded;
1276: - a minor mistake is fixed in recherche_instruction_suivante();
1277: - some minor memory leaks are fixed in recherche_type() function. They only

1280: - INCR and DECR are written (with integer or variable argument);
1281: - CSWP and RSWP are added and tested;
1282: - a minor bug is fixed in analyse.c;
1283: - DEBIAN/control is added to build debian package;

1285: - PUTC and PUTR new intrinsics are added.
1286: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1287: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1288: VISIT does not find a name in level 1;
1289: - configure.in script is modified to add a new test (--enable-debug
1290: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1291: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1292: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1293: 'MATRIX' { 2 2 3 } GETR;
1294: - LOGSCALE intrinsic is improved and now, it can be used as
1295: { "main" "auxiliary" X Y } LOGSCALE;
1296: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1297: same than AXES:
1298: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1299: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1300: { { -10 10 } "automatic" } SCALE.
1301: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1302: because it changes only the dimension of the screen. To have a logarithmic
1303: scale, you must use LOGSCALE intrinsic:
1304: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1305: screen on second scale;
1306: - { X X } autoscale and { Y Y } logscale are now invalid;
1307: - *D is added (depth multiplication, for 3D graphics);
1308: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1309: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1310: - a major bug is fixed in GETI instrinsic when it is used with a name
1311: that contains a matrix or a vector (bad upper bounds conditions in
1312: incrementation);
1313: - DISP intrinsic now uses the 33-th flag. When it is not set
1314: (default), a final carriage return is sent to the terminal;
1315: - AXES intrinsic only takes a list that can contains the keywork
1316: "main" or "auxiliary". Before this modification, this keyword was in
1317: the first stack level;
1318: - vim syntax file is upgraded;
1319: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1320: option;
1321: - LAST is now disabled in the main loop of INT intrinsic;
1322: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1323: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1324: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1325: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1326: in 0);
1327: - LAST is disabled in the main loop of DRAW intrinsic;
1328: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1329: evaluation of an equation, the system stack is returned corrupted to the
1330: sequencer;
1331: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1332: of a loop are not integer or real.
1333: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1334: - the compilation stage aborts with an error message when two definitions
1335: have the same name. To improve the compilation() subroutine, I have to
1336: add some tests in gestion_variables.c;
1337: - recherche_type() subroutine ad some other connex subroutines are improved.
1338: Now, some syntax errors about object are caught and do not perform sequencer
1339: hangup;

1341: - Makefile.am's and configure.in scripts are improved.
1342: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1343: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1344: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1345: the boxwidth, 1 by default);
1346: - recherche_type() is rewritten to be faster;
1347: - gsl is upgraded (release 1.3);
1348: - ncurses is upgraded and patched (release 5.3);
1349: - recherche_instruction_suivante() is fixed (string research with included
1350: '"') and rewritten to be faster;
1351: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1352: segfault.
1353: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1361: - a minor bug is fixed in evaluation subroutine;
1362: - vim syntax file is improved;
1363: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1364: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1365: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1366: is a quick and dirty workaround...);
1367: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1368: - rplconvert is improved.
1369: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1385: Now, an expression such as 'A+' returns an error when it is analyzed;
1386: - VISIT intrinsic is added;
1387: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1388: normal mode.

1476: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1477: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1478: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1479: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1480: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1481:
1482: Newton:[~/rpl/rpl] > time make install
1483: ...
1484: real 338m39.623s
1485: user 324m32.290s
1486: sys 10m47.380s
1487: Newton:[~/rpl/rpl] >
1488:
1489: I don't know if you will compile this language on old worstations, but
1490: it is usable ;-) ;
1491: - SYSEVAL is improved. An external program can be called without any shell.
1492: Thus, even if the sticky bit is set, RPL/2 can not give a shell root when
