1: * Thu Dec 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
2: - ncurses is upgraded;
3: - regression introduced bt 4.0.19 is fixed in signal management.
4: Interruption1() can be called from itself and raises bus error (on sparc) or
5: segmentation fault;
6: - sqlite is upgraded to 3.7.4;
7: - OpenSSL is upgraded to 1.0.0c;
8: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);
9: - characters are tested in recherche_type() to avoid names like '12+';
10: - sqlite is upgraded to 3.7.3;
11: - gnuplot is upgraded to 4.4.2 due to major bugs.
12: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
13: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
14: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
15: corruption. As internal memory management have been improved, a best fit
16: allocator like ptmalloc3 is not required anymore;
17: - gnuplot is upgraded to 4.4.1;
18: - deadlock is fixed in signal handlers: same mutex was used in standard
19: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
20: and signal handlers. A new signal handler specific mutex is added;
21: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
22: that has to be evaluated by ->NUM;
23: - rplfile build process is modify to be sure that rplfile is not modified
24: after rpl build stage (to be sure that rplfile checksum is not modified after
25: rpl compilation);
26: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
27: modified to remove yacc code and renamed;
28: - some workarounds have been written to not use buggy klibc SystemV IPCS.
29: ABORT now works on eComStation;
30: - sqlite is upgraded to 3.7.2;
31: - bug is fixed in software interrupts. When both process have different PID,
32: parent process was not interrupted if it is not group master process. To fix
33: this bug, SIGINJECT signal is not sent by child process but by control thread
34: in parent process;
35: - minor bug is fixed in data injection (POKE) that does not work as expected
36: when child process is protected by NRPROC.
37: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
38: - --enable-sysv-sems is added to configure script to use SystemV semaphores
39: functions instead of POSIX functions. This function is disabled or forced on
40: systems that does not provide correct POSIX or SysV semaphores subsystem;
41: - a dirty but not quick patch is written to workaround broken siginfo
42: structures. This patch has been successfully tested. It uses a segment of
43: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
44: (Unix PID);
45: - some OpenBSD's hacks are added;
46: - broken siginfo->si_pid field is now checked by configure script;
47: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
48: - random generator is cloned by SPAWN;

56: - TOKENIZE is now able to convert escape sequences;
57: - ATPOKE and CLRATPOKE new intrinsics are added;
58: - --enable-full-static configure flag is added. With this flag, mysql and
59: postgresql libraries are statically linked in rpl executable;
60: - units Makefile is modified to avoid readline and ncurses usages;
61: - sqlite is upgraded to 3.7.0.1;
62: - units is upgraded to 1.88;
63: - another major bug is fixed in the same variable creation subroutine.
64: Level 0 and 1 variables adresses were swapped when a global variable masked
65: a name of RPL/2 routine;
66: - major bug is fixed in global variable creation subroutine. When a global
67: variable was created and when a local variable existed with the same name,
68: computed address of global variable was wrong;
69: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
70: is forced in front of all libraries.
71: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
72: - BACKTRACE intrinsic is added;
73: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
74: when this structure is included in IFERR/THEN/END structure and when an error is
75: caught;
76: - major bug is fixed in analyse() subroutine. When evaluation() returned error
77: in a compiled program, analyse() caught this error twice and randomly aborted
78: with a segmentation error;
79: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
80: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
81: signals;
82: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
83: matrix.
84: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
85: - minor bug is fixed in evaluation() subroutine. With this patch, same program
86: returns same result with or without -p flag;

93: - version verification is added to shared objects;
94: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
95: linux (false mremap() prototype);

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

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

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

229: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
230: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
231: signals sent to main process were not caught because DAEMON did not replace
232: old pid by new one;
233: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
234: evaluation when an error is reported from a subroutine in another subroutine.
235: For example, error was not caught in following program when it is executed with
236: -p option :
237: TEST << iferr TEST2 then end >>
238: TEST2 << 0 inv >>
239: - major bug is fixed in variable management. Some local variables were
240: seen as global ones;
241: - major bug is fixed in rplcore. Rplcore entered in dead lock when
242: script file contains a multibyte character;
243: - IN intrinsic is added;
244: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
245: returned false ;
246: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
247: programs;
248: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
249: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
250: strings were never closed;
251: - some bugs have been fixed in file management;

253: - major bug is fixed in -A command line option (NULL character is missing);
254: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
255: made by blocks (1024 bytes). When an incomplete multibyte sequence is
256: encountered at end of block, subroutine aborts with an execution error;
257: - major bug is fixed in OPEN (TCP/IPv4 sockets).
258: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
259: - DISP now locks stdout;
260: - rpliconv is added to replace standard iconv provided by operating system.
261: Indeed, conversion between different encodages requires transliteration
262: that is not offered by some iconv utility;
263: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
264: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
265: not be found), SYSEVAL enters in a dead lock;
266: - fprintf is replaced by some functions that allow transliterations between
267: locales;
268: - '"' can now be used in strings ("\"");
269: - iconv is called with -c in preprocessor stage. It is done to write
270: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
271: - double free is fixed in liberation() (type SQL, only occurs when locale is
272: set);
273: - LOCALIZATION, UCASE and LCASE are added;
274: - major bug is fixed in EXIT intrinsic that was able to return a false
275: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
276: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
277: used in onLoading from shared library, USE was pushed on stack as algebraic
278: expression;
279: - libiconv is upgraded to 1.13.1;
280: - gnuplot is upgraded to 4.2.6;
281: - gsl is upgraded to 1.13.

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

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

455: SQLQUERY. With all new programs, you can open a real connection to databases;
456: - NRPROC is added. This new intrinsic is used to catch error from child
457: process. Without NRPROC, any errors returned by child process cause
458: main process to abort;
459: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
460: starts a new process). There are no mutexes in RPL/2 because all spawned process
461: use specific context. Nevertheless, shared variables and associated mutexes
462: should be added;

757: - external wrapper (rplplot) is written to force usage of gnuplot provided
758: by RPL/2 if it is built during build process. If this build does not exist,
759: it tries to launch regular gnuplot;
760: - gnuplot is added to source tree to avoid some trouble between preinstalled
761: gnuplot and release used by RPL/2. This addition to source tree is
762: required by some incompatibility between gnuplot releases;
763: - Lapack is upgraded to 3.1.1 release;
764: - GSL is upgraded to 1.9 revision;

788: #!/usr/local/bin/rpl -sc
789:
790: TEST
791: <<
792: 1 1000 start VAR_S VAR_S2 next
793: >>
794:
795: VAR_S
796: <<
797: static 3 -> C << C disp 'C' incr if C 10 > then 'C' volatile end >>

1185: 2: integer (number of column to be inserted)
1186: 1: column matrix to be inserted;
1187: - major bug was discovered in interface_gnuplot(). It only occurs when

1196: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1197: - SLICESCALE intrinsic is added. Its syntax is
1198: { "automatic" nb_of_levels }
1199: { "discrete" l1 l2 l3 ... }
1200: { "incremental" start incr }
1201: { "incremental" start incr end }
1202: { "automatic" } (default);

1204: - flag 52 is used to automatically update graphics;
1205: - man pages are updated;
1206: - evaluation() is modified to perform evaluation of expressions that contain
1207: '=';
1208: - a minor bug is fixed in AXES intrinsic;
1209: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1210: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1211: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1212: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1213: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1229: - SCLS is added;
1230: - DRWS now uses COLS to draw 2D graphics;
1231: - PPAR and SPAR are written. SPAR returns a list that contains the
1232: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1233: statistical variable, or "DISABLED" if its type is not one of the type of
1234: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1235: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1236: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1237: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1238: disabled. Arguments of EXTERNAL are case sensitive because the external
1239: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1240: of known external functions but add the new list to the last. { "all" }
1241: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1242: external names of the known functions;
1243: - mkrplso.in is modified.
1244: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1245: - vim syntax file is upgraded;
1246: - a minor mistake is fixed in recherche_instruction_suivante();
1247: - some minor memory leaks are fixed in recherche_type() function. They only

1255: - PUTC and PUTR new intrinsics are added.
1256: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1257: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1258: VISIT does not find a name in level 1;
1259: - configure.in script is modified to add a new test (--enable-debug
1260: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1261: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1262: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1263: 'MATRIX' { 2 2 3 } GETR;
1264: - LOGSCALE intrinsic is improved and now, it can be used as
1265: { "main" "auxiliary" X Y } LOGSCALE;
1266: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1267: same than AXES:
1268: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1269: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1270: { { -10 10 } "automatic" } SCALE.
1271: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1272: because it changes only the dimension of the screen. To have a logarithmic
1273: scale, you must use LOGSCALE intrinsic:
1274: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1275: screen on second scale;
1276: - { X X } autoscale and { Y Y } logscale are now invalid;
1277: - *D is added (depth multiplication, for 3D graphics);
1278: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1279: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1280: - a major bug is fixed in GETI instrinsic when it is used with a name
1281: that contains a matrix or a vector (bad upper bounds conditions in
1282: incrementation);
1283: - DISP intrinsic now uses the 33-th flag. When it is not set
1284: (default), a final carriage return is sent to the terminal;
1285: - AXES intrinsic only takes a list that can contains the keywork
1286: "main" or "auxiliary". Before this modification, this keyword was in
1287: the first stack level;
1288: - vim syntax file is upgraded;
1289: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1290: option;
1291: - LAST is now disabled in the main loop of INT intrinsic;
1292: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1293: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1294: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1295: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1296: in 0);
1297: - LAST is disabled in the main loop of DRAW intrinsic;
1298: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1299: evaluation of an equation, the system stack is returned corrupted to the
1300: sequencer;
1301: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1302: of a loop are not integer or real.
1303: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1311: - Makefile.am's and configure.in scripts are improved.
1312: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1313: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1314: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1315: the boxwidth, 1 by default);
1316: - recherche_type() is rewritten to be faster;
1317: - gsl is upgraded (release 1.3);
1318: - ncurses is upgraded and patched (release 5.3);
1319: - recherche_instruction_suivante() is fixed (string research with included
1320: '"') and rewritten to be faster;

1331: - a minor bug is fixed in evaluation subroutine;
1332: - vim syntax file is improved;
1333: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1334: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1335: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1336: is a quick and dirty workaround...);
1337: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1338: - rplconvert is improved.
1339: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1446: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1447: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1448: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1449: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1450: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1451:
1452: Newton:[~/rpl/rpl] > time make install
1453: ...
1454: real 338m39.623s
1455: user 324m32.290s
