1: * Wed Sep 15 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
2: - gnuplot is upgraded to 4.4.1;
3: - deadlock is fixed in signal handlers: same mutex was used in standard
4: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
5: and signal handlers. A new signal handler specific mutex is added;
6: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
7: that has to be evaluated by ->NUM;
8: - rplfile build process is modify to be sure that rplfile is not modified
9: after rpl build stage (to be sure that rplfile checksum is not modified after
10: rpl compilation);
11: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
12: modified to remove yacc code and renamed;
13: - some workarounds have been written to not use buggy klibc SystemV IPCS.
14: ABORT now works on eComStation;
15: - sqlite is upgraded to 3.7.2;
16: - bug is fixed in software interrupts. When both process have different PID,
17: parent process was not interrupted if it is not group master process. To fix
18: this bug, SIGINJECT signal is not sent by child process but by control thread
19: in parent process;
20: - minor bug is fixed in data injection (POKE) that does not work as expected
21: when child process is protected by NRPROC.
22: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
23: - --enable-sysv-sems is added to configure script to use SystemV semaphores
24: functions instead of POSIX functions. This function is disabled or forced on
25: systems that does not provide correct POSIX or SysV semaphores subsystem;
26: - a dirty but not quick patch is written to workaround broken siginfo
27: structures. This patch has been successfully tested. It uses a segment of
28: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
29: (Unix PID);
30: - some OpenBSD's hacks are added;
31: - broken siginfo->si_pid field is now checked by configure script;
32: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

46: - sqlite is upgraded to 3.7.0.1;
47: - units is upgraded to 1.88;
48: - another major bug is fixed in the same variable creation subroutine.
49: Level 0 and 1 variables adresses were swapped when a global variable masked
50: a name of RPL/2 routine;
51: - major bug is fixed in global variable creation subroutine. When a global
52: variable was created and when a local variable existed with the same name,
53: computed address of global variable was wrong;
54: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
55: is forced in front of all libraries.
56: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
57: - BACKTRACE intrinsic is added;

59: when this structure is included in IFERR/THEN/END structure and when an error is
60: caught;
61: - major bug is fixed in analyse() subroutine. When evaluation() returned error
62: in a compiled program, analyse() caught this error twice and randomly aborted
63: with a segmentation error;
64: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
65: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
66: signals;

89: - PROCID is added;
90: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
91: and to not use swap;
92: - major bug is fixed in sql support. SQL connections were closed in all chield
93: process;
94: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
95: discovered in Solaris thread safe allocators (libmalloc and libumem) that
96: are first fit class allocators. Solaris libmtmalloc works better and is
97: a best fit class allocator but its performance is poor than ptmalloc3
98: performance;
99: - major bug is fixed in ROW+ intrinsic (new row was not added where it
100: should);
101: - minor bugs are fixed in interruptions.c (semaphores values when error is

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

161: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
162: - in formatted file, string format returned a variable length string even if
163: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
164: a variable length string and 'CHARACTER*(n)' a fixed length string;
165: - keyed access files support is added. Currently, only formatted files are
166: supported;
167: - direct access files support is added. Currenlty, these files can only be used
168: in formatted mode;
169: - virtual variables are now writte in UTF-8 and all special characters
170: in string are escaped;
171: - all formatted files are now converted into UTF-8;
172: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
173: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
174: each execution (md5 and sha1 sums) to enhance security. If one of these tools
175: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
176: on a non recoverable system error;
177: - openssl and sqlite3 libraries are added;
178: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
179: variable indicates RPL/2 root directory. If it is not set, root path
180: is given by configure script (d_exec_path);
181: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

214: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
215: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
216: signals sent to main process were not caught because DAEMON did not replace
217: old pid by new one;
218: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
219: evaluation when an error is reported from a subroutine in another subroutine.
220: For example, error was not caught in following program when it is executed with
221: -p option :
222: TEST << iferr TEST2 then end >>
223: TEST2 << 0 inv >>
224: - major bug is fixed in variable management. Some local variables were
225: seen as global ones;
226: - major bug is fixed in rplcore. Rplcore entered in dead lock when
227: script file contains a multibyte character;
228: - IN intrinsic is added;
229: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
230: returned false ;
231: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
232: programs;
233: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
234: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

238: - major bug is fixed in -A command line option (NULL character is missing);
239: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
240: made by blocks (1024 bytes). When an incomplete multibyte sequence is
241: encountered at end of block, subroutine aborts with an execution error;
242: - major bug is fixed in OPEN (TCP/IPv4 sockets).
243: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
244: - DISP now locks stdout;
245: - rpliconv is added to replace standard iconv provided by operating system.
246: Indeed, conversion between different encodages requires transliteration
247: that is not offered by some iconv utility;
248: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
249: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
250: not be found), SYSEVAL enters in a dead lock;
251: - fprintf is replaced by some functions that allow transliterations between
252: locales;
253: - '"' can now be used in strings ("\"");
254: - iconv is called with -c in preprocessor stage. It is done to write
255: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
256: - double free is fixed in liberation() (type SQL, only occurs when locale is
257: set);
258: - LOCALIZATION, UCASE and LCASE are added;

262: used in onLoading from shared library, USE was pushed on stack as algebraic
263: expression;
264: - libiconv is upgraded to 1.13.1;
265: - gnuplot is upgraded to 4.2.6;
266: - gsl is upgraded to 1.13.

268: - pipe() is overwritten by a macro to avoid a system error. Communication
269: between process are done with pipes and these pipes are managed by a
270: specific asynchrone thread. If a script try to create more threads than
271: management thread can destroy, you can quickly achieve maximum number of
272: opened files and pipe() shall return a system error. This macro tries to create
273: pipes. If pipe() function returns an error, macro waits and retries. If
274: number of retries is greater than a hardcoded value, macro returns an error;
275: - major bug (deadlock) is fixed in process and thread management. I hope
276: this bug shall be the last one;
277: - major bug is fixed in DET intrinsic (determinant was computed without LU
278: diagonalization);

283: - all process management is rewritten to avoid usage of defunct process
284: or thread number;
285: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
286: was called before a pending interruption5 (SIGFSTOP), signal handler uses
287: a freed semaphore and corrupts heap;
288: - CLRERR is added to erase previous errors;
289: - ERRN and ERRM return exception message and number;
290: - major bug is fixed in interruptions.c. All signal are now bufferised
291: when semaphore_liste_threads is null to avoid deadlock. This bug only
292: occured when STOP was sent to a dying thread or process (when this thread or
293: process was running retrait_thread());
294: - matrix rank is computed before matrix inversion;
295: - file locks are added to stdin and stdout. stderr is not locked because
296: all messages written by signal handlers are sent to stderr;

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

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

439: that all programs that worked with old SQL intrinsic can now work with
440: SQLQUERY. With all new programs, you can open a real connection to databases;
441: - NRPROC is added. This new intrinsic is used to catch error from child
442: process. Without NRPROC, any errors returned by child process cause
443: main process to abort;
444: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
445: starts a new process). There are no mutexes in RPL/2 because all spawned process
446: use specific context. Nevertheless, shared variables and associated mutexes
447: should be added;
448: - -D flag and DAEMONIZE intrinsic have been added;
449: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

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

596: - -p option is added. With this option, all scripts are compiled before
597: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
598: 40% faster;
599: - read and write operations in pipe() are rewritten to be sure that such
600: operations are atomic;

742: - external wrapper (rplplot) is written to force usage of gnuplot provided
743: by RPL/2 if it is built during build process. If this build does not exist,
744: it tries to launch regular gnuplot;
745: - gnuplot is added to source tree to avoid some trouble between preinstalled
746: gnuplot and release used by RPL/2. This addition to source tree is
747: required by some incompatibility between gnuplot releases;
748: - Lapack is upgraded to 3.1.1 release;
749: - GSL is upgraded to 1.9 revision;

1161: - BESSEL intrinsic is added. Syntax:
1162: 3: type ("J", "K", "I", "Y", "j", "k", "i", "y")
1163: 2: order (integer or real)
1164: 1: x;
1165: - ->Q intrinsic is added;
1166: - major bug is fixed in C->R intrinsic;
1167: - ROW+ and ROW- are added and tested;
1168: - COL+ and COL- are added and tested. Syntax:
1169: 3: matrix
1170: 2: integer (number of column to be inserted)
1171: 1: column matrix to be inserted;
1172: - major bug was discovered in interface_gnuplot(). It only occurs when
1173: the subroutine reduces the graphical depth. It is now fixed;
1174: - Some mistakes are been fixed in vim syntax file;
1175: - SX2, SY2 and SXY are added;
1176: - SX and SY statistical intrinsics are added;
1177: - DEBIAN control file is fixed;

1179: letter, legal, executive;
1180: - PPAR is modified to include current graphic type.
1181: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1182: - SLICESCALE intrinsic is added. Its syntax is
1183: { "automatic" nb_of_levels }
1184: { "discrete" l1 l2 l3 ... }
1185: { "incremental" start incr }
1186: { "incremental" start incr end }
1187: { "automatic" } (default);
1188: - a minor bug (in last stack) is fixed in AXES intrinsic
1189: - flag 52 is used to automatically update graphics;
1190: - man pages are updated;
1191: - evaluation() is modified to perform evaluation of expressions that contain
1192: '=';
1193: - a minor bug is fixed in AXES intrinsic;
1194: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1195: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1196: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1197: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1198: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;
1199: - PLOTTER is added to draw statistical clouds with lines;
1200: - C and H source files now include vim parameters;
1201: - vim syntax file is modified to include new intrinsics;
1202: - static archive is modified to include all required libraries needed by

1204: * Sun May 4 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6i (RPL/2)
1205: - '=' is added and tested;
1206: - XCOL and YCOL are added;
1207: - a minor bug in analyse_syntaxique() is fixed;
1208: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1209: structure. ELSE is modified to return an error when ELSE appears in
1210: an ELSE/END structure;
1211: - a major bug is fixed in CYCLE;
1212: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1213: sequencer continues after the end of this loop;
1214: - SCLS is added;
1215: - DRWS now uses COLS to draw 2D graphics;
1216: - PPAR and SPAR are written. SPAR returns a list that contains the
1217: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1218: statistical variable, or "DISABLED" if its type is not one of the type of
1219: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1220: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1221: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1222: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1223: disabled. Arguments of EXTERNAL are case sensitive because the external
1224: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1225: of known external functions but add the new list to the last. { "all" }
1226: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1227: external names of the known functions;
1228: - mkrplso.in is modified.
1229: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1230: - vim syntax file is upgraded;
1231: - a minor mistake is fixed in recherche_instruction_suivante();
1232: - some minor memory leaks are fixed in recherche_type() function. They only
1233: occurs when a syntax error is detected;
1234: - #error and #warning preprocessor macros are added;
1235: - INCR and DECR are written (with integer or variable argument);
1236: - CSWP and RSWP are added and tested;
1237: - a minor bug is fixed in analyse.c;
1238: - DEBIAN/control is added to build debian package;
1239: - SCALE is fixed and improved ("automatic" keyword);
1240: - PUTC and PUTR new intrinsics are added.
1241: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1242: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1243: VISIT does not find a name in level 1;
1244: - configure.in script is modified to add a new test (--enable-debug
1245: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1246: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1247: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1248: 'MATRIX' { 2 2 3 } GETR;
1249: - LOGSCALE intrinsic is improved and now, it can be used as
1250: { "main" "auxiliary" X Y } LOGSCALE;
1251: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1252: same than AXES:
1253: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1254: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1255: { { -10 10 } "automatic" } SCALE.
1256: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1257: because it changes only the dimension of the screen. To have a logarithmic
1258: scale, you must use LOGSCALE intrinsic:
1259: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1260: screen on second scale;
1261: - { X X } autoscale and { Y Y } logscale are now invalid;
1262: - *D is added (depth multiplication, for 3D graphics);
1263: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1264: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1265: - a major bug is fixed in GETI instrinsic when it is used with a name
1266: that contains a matrix or a vector (bad upper bounds conditions in
1267: incrementation);
1268: - DISP intrinsic now uses the 33-th flag. When it is not set
1269: (default), a final carriage return is sent to the terminal;
1270: - AXES intrinsic only takes a list that can contains the keywork
1271: "main" or "auxiliary". Before this modification, this keyword was in
1272: the first stack level;
1273: - vim syntax file is upgraded;
1274: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1275: option;
1276: - LAST is now disabled in the main loop of INT intrinsic;
1277: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1278: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1279: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1280: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1281: in 0);
1282: - LAST is disabled in the main loop of DRAW intrinsic;
1283: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1284: evaluation of an equation, the system stack is returned corrupted to the
1285: sequencer;
1286: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1287: of a loop are not integer or real.
1288: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1289: - the compilation stage aborts with an error message when two definitions
1290: have the same name. To improve the compilation() subroutine, I have to
1291: add some tests in gestion_variables.c;
1292: - recherche_type() subroutine ad some other connex subroutines are improved.
1293: Now, some syntax errors about object are caught and do not perform sequencer
1294: hangup;

1296: - Makefile.am's and configure.in scripts are improved.
1297: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1298: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1299: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1300: the boxwidth, 1 by default);
1301: - recherche_type() is rewritten to be faster;
1302: - gsl is upgraded (release 1.3);
1303: - ncurses is upgraded and patched (release 5.3);
1304: - recherche_instruction_suivante() is fixed (string research with included
1305: '"') and rewritten to be faster;
1306: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1307: segfault.

1316: - a minor bug is fixed in evaluation subroutine;
1317: - vim syntax file is improved;
1318: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1319: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1320: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1321: is a quick and dirty workaround...);
1322: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1323: - rplconvert is improved.
1324: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1340: Now, an expression such as 'A+' returns an error when it is analyzed;
1341: - VISIT intrinsic is added;
1342: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1343: normal mode.

1431: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1432: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1433: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1434: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1435: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1436:
1437: Newton:[~/rpl/rpl] > time make install
1438: ...
1439: real 338m39.623s
1440: user 324m32.290s
