30: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
31: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
32: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
33: corruption. As internal memory management have been improved, a best fit
34: allocator like ptmalloc3 is not required anymore;
35: - gnuplot is upgraded to 4.4.1;
36: - deadlock is fixed in signal handlers: same mutex was used in standard
37: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
38: and signal handlers. A new signal handler specific mutex is added;
39: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
40: that has to be evaluated by ->NUM;

50: parent process was not interrupted if it is not group master process. To fix
51: this bug, SIGINJECT signal is not sent by child process but by control thread
52: in parent process;
53: - minor bug is fixed in data injection (POKE) that does not work as expected
54: when child process is protected by NRPROC.
55: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
56: - --enable-sysv-sems is added to configure script to use SystemV semaphores
57: functions instead of POSIX functions. This function is disabled or forced on
58: systems that does not provide correct POSIX or SysV semaphores subsystem;
59: - a dirty but not quick patch is written to workaround broken siginfo
60: structures. This patch has been successfully tested. It uses a segment of
61: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
62: (Unix PID);
63: - some OpenBSD's hacks are added;
64: - broken siginfo->si_pid field is now checked by configure script;
65: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

82: Level 0 and 1 variables adresses were swapped when a global variable masked
83: a name of RPL/2 routine;
84: - major bug is fixed in global variable creation subroutine. When a global
85: variable was created and when a local variable existed with the same name,
86: computed address of global variable was wrong;
87: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
88: is forced in front of all libraries.

92: when this structure is included in IFERR/THEN/END structure and when an error is
93: caught;
94: - major bug is fixed in analyse() subroutine. When evaluation() returned error
95: in a compiled program, analyse() caught this error twice and randomly aborted
96: with a segmentation error;
97: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
98: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
99: signals;
100: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
101: matrix.
102: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

123: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
124: and to not use swap;
125: - major bug is fixed in sql support. SQL connections were closed in all chield
126: process;
127: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
128: discovered in Solaris thread safe allocators (libmalloc and libumem) that
129: are first fit class allocators. Solaris libmtmalloc works better and is
130: a best fit class allocator but its performance is poor than ptmalloc3
131: performance;
132: - major bug is fixed in ROW+ intrinsic (new row was not added where it
133: should);
134: - minor bugs are fixed in interruptions.c (semaphores values when error is
135: caught);
136: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
137: created by SPAWN;

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

194: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
195: - in formatted file, string format returned a variable length string even if
196: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
197: a variable length string and 'CHARACTER*(n)' a fixed length string;
198: - keyed access files support is added. Currently, only formatted files are
199: supported;
200: - direct access files support is added. Currenlty, these files can only be used
201: in formatted mode;

203: in string are escaped;
204: - all formatted files are now converted into UTF-8;
205: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
206: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
207: each execution (md5 and sha1 sums) to enhance security. If one of these tools
208: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
209: on a non recoverable system error;
210: - openssl and sqlite3 libraries are added;
211: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
212: variable indicates RPL/2 root directory. If it is not set, root path
213: is given by configure script (d_exec_path);
214: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

248: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
249: signals sent to main process were not caught because DAEMON did not replace
250: old pid by new one;
251: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
252: evaluation when an error is reported from a subroutine in another subroutine.
253: For example, error was not caught in following program when it is executed with
254: -p option :
255: TEST << iferr TEST2 then end >>
256: TEST2 << 0 inv >>
257: - major bug is fixed in variable management. Some local variables were
258: seen as global ones;

260: script file contains a multibyte character;
261: - IN intrinsic is added;
262: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
263: returned false ;

274: encountered at end of block, subroutine aborts with an execution error;
275: - major bug is fixed in OPEN (TCP/IPv4 sockets).
276: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
277: - DISP now locks stdout;
278: - rpliconv is added to replace standard iconv provided by operating system.
279: Indeed, conversion between different encodages requires transliteration
280: that is not offered by some iconv utility;
281: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
282: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

284: - fprintf is replaced by some functions that allow transliterations between
285: locales;
286: - '"' can now be used in strings ("\"");
287: - iconv is called with -c in preprocessor stage. It is done to write

298: - gnuplot is upgraded to 4.2.6;
299: - gsl is upgraded to 1.13.

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

319: was called before a pending interruption5 (SIGFSTOP), signal handler uses
320: a freed semaphore and corrupts heap;
321: - CLRERR is added to erase previous errors;
322: - ERRN and ERRM return exception message and number;
323: - major bug is fixed in interruptions.c. All signal are now bufferised
324: when semaphore_liste_threads is null to avoid deadlock. This bug only
325: occured when STOP was sent to a dying thread or process (when this thread or
326: process was running retrait_thread());
327: - matrix rank is computed before matrix inversion;
328: - file locks are added to stdin and stdout. stderr is not locked because
329: all messages written by signal handlers are sent to stderr;

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

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

451: static variable that is shared by multiple threads;
452: - '->' intrinsic is improved. All object copies have been avoided;
453: - -n flag is added to catch HUP signal. stderr and stdout are redirected
454: to a file, stdin is redirected to /dev/null when control process is killed;

472: that all programs that worked with old SQL intrinsic can now work with
473: SQLQUERY. With all new programs, you can open a real connection to databases;
474: - NRPROC is added. This new intrinsic is used to catch error from child
475: process. Without NRPROC, any errors returned by child process cause
476: main process to abort;
477: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
478: starts a new process). There are no mutexes in RPL/2 because all spawned process
479: use specific context. Nevertheless, shared variables and associated mutexes
480: should be added;

1163: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1164: if the main loop is in a program;
1165: - RPL/2 is tested with efence and valgrind;
1166: - configure.in script is modified;
1167: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1168: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1169: another gcc bug...
1170: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)

1203: 2: integer (number of column to be inserted)
1204: 1: column matrix to be inserted;
1205: - major bug was discovered in interface_gnuplot(). It only occurs when

1214: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1215: - SLICESCALE intrinsic is added. Its syntax is
1216: { "automatic" nb_of_levels }
1217: { "discrete" l1 l2 l3 ... }
1218: { "incremental" start incr }
1219: { "incremental" start incr end }
1220: { "automatic" } (default);

1222: - flag 52 is used to automatically update graphics;
1223: - man pages are updated;
1224: - evaluation() is modified to perform evaluation of expressions that contain
1225: '=';
1226: - a minor bug is fixed in AXES intrinsic;
1227: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1228: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1229: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1230: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1231: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1247: - SCLS is added;
1248: - DRWS now uses COLS to draw 2D graphics;
1249: - PPAR and SPAR are written. SPAR returns a list that contains the
1250: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1251: statistical variable, or "DISABLED" if its type is not one of the type of
1252: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1253: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1254: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1255: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1256: disabled. Arguments of EXTERNAL are case sensitive because the external
1257: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1258: of known external functions but add the new list to the last. { "all" }
1259: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1260: external names of the known functions;
1261: - mkrplso.in is modified.
1262: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1263: - vim syntax file is upgraded;
1264: - a minor mistake is fixed in recherche_instruction_suivante();
1265: - some minor memory leaks are fixed in recherche_type() function. They only

1273: - PUTC and PUTR new intrinsics are added.
1274: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1275: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1276: VISIT does not find a name in level 1;
1277: - configure.in script is modified to add a new test (--enable-debug
1278: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1279: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1280: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1281: 'MATRIX' { 2 2 3 } GETR;
1282: - LOGSCALE intrinsic is improved and now, it can be used as
1283: { "main" "auxiliary" X Y } LOGSCALE;
1284: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1285: same than AXES:
1286: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1287: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1288: { { -10 10 } "automatic" } SCALE.
1289: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1290: because it changes only the dimension of the screen. To have a logarithmic
1291: scale, you must use LOGSCALE intrinsic:
1292: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1293: screen on second scale;
1294: - { X X } autoscale and { Y Y } logscale are now invalid;
1295: - *D is added (depth multiplication, for 3D graphics);
1296: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1297: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1298: - a major bug is fixed in GETI instrinsic when it is used with a name
1299: that contains a matrix or a vector (bad upper bounds conditions in
1300: incrementation);
1301: - DISP intrinsic now uses the 33-th flag. When it is not set
1302: (default), a final carriage return is sent to the terminal;
1303: - AXES intrinsic only takes a list that can contains the keywork
1304: "main" or "auxiliary". Before this modification, this keyword was in
1305: the first stack level;
1306: - vim syntax file is upgraded;
1307: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1308: option;
1309: - LAST is now disabled in the main loop of INT intrinsic;
1310: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1311: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1312: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1313: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1314: in 0);
1315: - LAST is disabled in the main loop of DRAW intrinsic;
1316: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1317: evaluation of an equation, the system stack is returned corrupted to the
1318: sequencer;
1319: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1320: of a loop are not integer or real.
1321: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1322: - the compilation stage aborts with an error message when two definitions
1323: have the same name. To improve the compilation() subroutine, I have to
1324: add some tests in gestion_variables.c;
1325: - recherche_type() subroutine ad some other connex subroutines are improved.
1326: Now, some syntax errors about object are caught and do not perform sequencer
1327: hangup;
1328: - readline is upgraded (minor compilation bug with recent gcc);
1329: - Makefile.am's and configure.in scripts are improved.
1330: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1331: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1332: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1333: the boxwidth, 1 by default);
1334: - recherche_type() is rewritten to be faster;
1335: - gsl is upgraded (release 1.3);
1336: - ncurses is upgraded and patched (release 5.3);
1337: - recherche_instruction_suivante() is fixed (string research with included
1338: '"') and rewritten to be faster;
1339: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1340: segfault.
1341: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1349: - a minor bug is fixed in evaluation subroutine;
1350: - vim syntax file is improved;
1351: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1352: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1353: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1354: is a quick and dirty workaround...);
1355: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1356: - rplconvert is improved.
1357: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1373: Now, an expression such as 'A+' returns an error when it is analyzed;
1374: - VISIT intrinsic is added;
1375: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1376: normal mode.

1464: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1465: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1466: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1467: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1468: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1469:
1470: Newton:[~/rpl/rpl] > time make install
1471: ...
1472: real 338m39.623s
1473: user 324m32.290s
1474: sys 10m47.380s
1475: Newton:[~/rpl/rpl] >
1476:
1477: I don't know if you will compile this language on old worstations, but
1478: it is usable ;-) ;
1479: - SYSEVAL is improved. An external program can be called without any shell.
