12: * Mon Jun 20 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.0.prerelease.0 (RPL/2)
13: - New variable management is written. Please note that -p flag does not work
14: and all multithread/multitask capabilities have been disabled until this
15: new subsystem shall be validated.
16: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
17: - major bug is fixed in STD format (1E7 sq prints 1);
18: - major bug is fixed in READ intrinsic (socket). This bug was introduced
19: by a new feature in glibc.
20: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
21: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
22: "ALL" IMPLICIT when it runs in interactive mode;
23: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
24: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
25: to use SAVE to manipulate global variables;
26: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
27: subroutines;
28: - fix major memory access violation in evaluation subroutine. Only occurs
29: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
30: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
31: when X was a vector or a table.
32: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)
33: - Gnuplot is upgraded;
34: - flag 34 is now used to enable or disable control character evaluation;
35: - major bug is fixed in P->R intrinsic function when argument type is
36: complex and degree mode is set;
37: - L->T and T->L are added;
38: - OLD filetype is fixed;
39: - FLOW socket support is added;
40: - FLOW sequential files are added;
41: - new escape sequence is added to handle flow files (\x + hexadecimal code).
42: Known escape sequences are \", \b, \n, \t, \x?? and \\.
43: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
44: - Ncurses is upgraded to 5.8;
45: - ALARM is fixed by filling isdst field;
46: - catch ECONNRESET in write intrinsic to return an execution error instead of
47: system one;
48: - fix a typo in HELP intrinsic;
49: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;
50: - Lapack is upgraded to 3.3.0;
51: - libmtmalloc is now default Solaris allocator;
52: - ncurses is upgraded;
53: - regression introduced by 4.0.19 is fixed in signal management.
54: Interruption1() could be called from itself and raises bus error (on sparc) or
55: segmentation fault;
56: - sqlite is upgraded to 3.7.4;
57: - OpenSSL is upgraded to 1.0.0c;
58: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);
59: - characters are tested in recherche_type() to avoid names like '12+';
60: - gnuplot is upgraded to 4.4.2 due to major bugs.
61: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
62: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
63: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
64: corruption. As internal memory management have been improved, a best fit
65: allocator like ptmalloc3 is not required anymore;
66: - gnuplot is upgraded to 4.4.1;
67: - deadlock is fixed in signal handlers: same mutex was used in standard
68: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
69: and signal handlers. A new signal handler specific mutex is added;
70: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
71: that has to be evaluated by ->NUM;
72: - rplfile build process is modify to be sure that rplfile is not modified
73: after rpl build stage (to be sure that rplfile checksum is not modified after
74: rpl compilation);
75: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
76: modified to remove yacc code and renamed;
77: - some workarounds have been written to not use buggy klibc SystemV IPCS.
78: ABORT now works on eComStation;
79: - sqlite is upgraded to 3.7.2;
80: - bug is fixed in software interrupts. When both process have different PID,
81: parent process was not interrupted if it is not group master process. To fix
82: this bug, SIGINJECT signal is not sent by child process but by control thread
83: in parent process;
84: - minor bug is fixed in data injection (POKE) that does not work as expected
85: when child process is protected by NRPROC.
86: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
87: - --enable-sysv-sems is added to configure script to use SystemV semaphores
88: functions instead of POSIX functions. This function is disabled or forced on
89: systems that does not provide correct POSIX or SysV semaphores subsystem;
90: - a dirty but not quick patch is written to workaround broken siginfo
91: structures. This patch has been successfully tested. It uses a segment of
92: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
93: (Unix PID);
94: - some OpenBSD's hacks are added;
95: - broken siginfo->si_pid field is now checked by configure script;
96: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
97: - random generator is cloned by SPAWN;
98: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;

105: - TOKENIZE is now able to convert escape sequences;
106: - ATPOKE and CLRATPOKE new intrinsics are added;
107: - --enable-full-static configure flag is added. With this flag, mysql and
108: postgresql libraries are statically linked in rpl executable;
109: - units Makefile is modified to avoid readline and ncurses usages;
110: - sqlite is upgraded to 3.7.0.1;
111: - units is upgraded to 1.88;
112: - another major bug is fixed in the same variable creation subroutine.
113: Level 0 and 1 variables adresses were swapped when a global variable masked
114: a name of RPL/2 routine;
115: - major bug is fixed in global variable creation subroutine. When a global
116: variable was created and when a local variable existed with the same name,
117: computed address of global variable was wrong;
118: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
119: is forced in front of all libraries.
120: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
121: - BACKTRACE intrinsic is added;
122: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
123: when this structure is included in IFERR/THEN/END structure and when an error is
124: caught;
125: - major bug is fixed in analyse() subroutine. When evaluation() returned error
126: in a compiled program, analyse() caught this error twice and randomly aborted
127: with a segmentation error;
128: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
129: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
130: signals;
131: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
132: matrix.
133: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
134: - minor bug is fixed in evaluation() subroutine. With this patch, same program

142: - version verification is added to shared objects;
143: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
144: linux (false mremap() prototype);
145: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.

149: - major bug is fixed in IFERR structure. Only occurs in compiled program;
150: - major bug is fixed in copie_objet() and liberation(). Only concerns
151: format in FCH (file descriptor) and SCK (socket descriptor);
152: - debug routines are improved;
153: - PROCID is added;
154: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
155: and to not use swap;
156: - major bug is fixed in sql support. SQL connections were closed in all chield
157: process;
158: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
159: discovered in Solaris thread safe allocators (libmalloc and libumem) that
160: are first fit class allocators. Solaris libmtmalloc works better and is
161: a best fit class allocator but its performance is poor than ptmalloc3
162: performance;
163: - major bug is fixed in ROW+ intrinsic (new row was not added where it
164: should);
165: - minor bugs are fixed in interruptions.c (semaphores values when error is
166: caught);
167: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
168: created by SPAWN;
169: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
170: ATEXIT. If it receives SIGFABORT, it does not;
171: - ONEXIT is renamed in ATEXIT;
172: - ONEXIT new intrinsic is added.

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

226: - in formatted file, string format returned a variable length string even if
227: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
228: a variable length string and 'CHARACTER*(n)' a fixed length string;
229: - keyed access files support is added. Currently, only formatted files are
230: supported;
231: - direct access files support is added. Currenlty, these files can only be used
232: in formatted mode;
233: - virtual variables are now writte in UTF-8 and all special characters
234: in string are escaped;
235: - all formatted files are now converted into UTF-8;
236: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
237: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
238: each execution (md5 and sha1 sums) to enhance security. If one of these tools
239: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
240: on a non recoverable system error;
241: - openssl and sqlite3 libraries are added;
242: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
243: variable indicates RPL/2 root directory. If it is not set, root path
244: is given by configure script (d_exec_path);
245: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

278: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
279: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
280: signals sent to main process were not caught because DAEMON did not replace
281: old pid by new one;
282: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
283: evaluation when an error is reported from a subroutine in another subroutine.
284: For example, error was not caught in following program when it is executed with
285: -p option :
286: TEST << iferr TEST2 then end >>
287: TEST2 << 0 inv >>
288: - major bug is fixed in variable management. Some local variables were
289: seen as global ones;

306: - major bug is fixed in OPEN (TCP/IPv4 sockets).
307: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
308: - DISP now locks stdout;
309: - rpliconv is added to replace standard iconv provided by operating system.
310: Indeed, conversion between different encodages requires transliteration
311: that is not offered by some iconv utility;
312: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
313: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
314: not be found), SYSEVAL enters in a dead lock;
315: - fprintf is replaced by some functions that allow transliterations between
316: locales;
317: - '"' can now be used in strings ("\"");
318: - iconv is called with -c in preprocessor stage. It is done to write
319: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
320: - double free is fixed in liberation() (type SQL, only occurs when locale is
321: set);
322: - LOCALIZATION, UCASE and LCASE are added;

324: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
325: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
326: used in onLoading from shared library, USE was pushed on stack as algebraic
327: expression;
328: - libiconv is upgraded to 1.13.1;
329: - gnuplot is upgraded to 4.2.6;
330: - gsl is upgraded to 1.13.

332: - pipe() is overwritten by a macro to avoid a system error. Communication
333: between process are done with pipes and these pipes are managed by a
334: specific asynchrone thread. If a script try to create more threads than
335: management thread can destroy, you can quickly achieve maximum number of
336: opened files and pipe() shall return a system error. This macro tries to create
337: pipes. If pipe() function returns an error, macro waits and retries. If
338: number of retries is greater than a hardcoded value, macro returns an error;
339: - major bug (deadlock) is fixed in process and thread management. I hope
340: this bug shall be the last one;
341: - major bug is fixed in DET intrinsic (determinant was computed without LU
342: diagonalization);
343: - SWAPCNTXT is added;
344: - minor bug is fixed in Makefile.am (licences rule).
345: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)

347: - all process management is rewritten to avoid usage of defunct process
348: or thread number;
349: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
350: was called before a pending interruption5 (SIGFSTOP), signal handler uses
351: a freed semaphore and corrupts heap;
352: - CLRERR is added to erase previous errors;
353: - ERRN and ERRM return exception message and number;
354: - major bug is fixed in interruptions.c. All signal are now bufferised
355: when semaphore_liste_threads is null to avoid deadlock. This bug only
356: occured when STOP was sent to a dying thread or process (when this thread or
357: process was running retrait_thread());
358: - matrix rank is computed before matrix inversion;
359: - file locks are added to stdin and stdout. stderr is not locked because
360: all messages written by signal handlers are sent to stderr;
361: - configure.in script is modified to test gcc version and avoid a bug in

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

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

780: - --enable-debug is modified. Now, return can be defined to print
781: on stdout its position in source code (line and function);
782: - minor bug is fixed in recherche_type(). Don't forget that space
783: are not significant in algebraic expression:
784: '12 3+ 12 X' is the same expression than '123+12X';

806: - external wrapper (rplplot) is written to force usage of gnuplot provided
807: by RPL/2 if it is built during build process. If this build does not exist,
808: it tries to launch regular gnuplot;
809: - gnuplot is added to source tree to avoid some trouble between preinstalled
810: gnuplot and release used by RPL/2. This addition to source tree is

859: With STATIC, next variables created by '->' are static;
860: - PROTECT and UNPROTECT are added to protect variables against write
861: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
862: versions of PROTECT and UNPROTECT that only deal with global variables
863: (see RCL/SAVE);
864: - variable management routines have been rewritten. The new ones are
865: uncompatible with the old ones. Before these changes, a local variable
866: was exported to a child subroutine, but cannot be modified into this
867: child subroutine. Now, a local variable is accessible only in its subroutine;
868: - SAVE intrinsic is added to manipulate global variables;

1186: (less parenthesis);
1187: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1188: on Debian distribution, but since cpp is in the default path, RPL/2 works
1189: fine...);
1190: - NOT is not correctly formatted in formateur.c:
1191: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1192: with a NOTZ function !
1193: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1194: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1195: if the main loop is in a program;
1196: - RPL/2 is tested with efence and valgrind;
1197: - configure.in script is modified;
1198: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1199: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1247: { "automatic" nb_of_levels }
1248: { "discrete" l1 l2 l3 ... }
1249: { "incremental" start incr }
1250: { "incremental" start incr end }

1259: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1260: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1261: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1278: - SCLS is added;
1279: - DRWS now uses COLS to draw 2D graphics;
1280: - PPAR and SPAR are written. SPAR returns a list that contains the
1281: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1282: statistical variable, or "DISABLED" if its type is not one of the type of
1283: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1284: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1285: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1286: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1287: disabled. Arguments of EXTERNAL are case sensitive because the external
1288: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1289: of known external functions but add the new list to the last. { "all" }
1290: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1291: external names of the known functions;
1292: - mkrplso.in is modified.
1293: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1294: - vim syntax file is upgraded;
1295: - a minor mistake is fixed in recherche_instruction_suivante();
1296: - some minor memory leaks are fixed in recherche_type() function. They only

1305: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1306: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1307: VISIT does not find a name in level 1;
1308: - configure.in script is modified to add a new test (--enable-debug
1309: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1310: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1311: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1312: 'MATRIX' { 2 2 3 } GETR;
1313: - LOGSCALE intrinsic is improved and now, it can be used as
1314: { "main" "auxiliary" X Y } LOGSCALE;
1315: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1316: same than AXES:
1317: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1318: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1319: { { -10 10 } "automatic" } SCALE.
1320: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1321: because it changes only the dimension of the screen. To have a logarithmic
1322: scale, you must use LOGSCALE intrinsic:
1323: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1324: screen on second scale;
1325: - { X X } autoscale and { Y Y } logscale are now invalid;
1326: - *D is added (depth multiplication, for 3D graphics);
1327: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1328: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1329: - a major bug is fixed in GETI instrinsic when it is used with a name
1330: that contains a matrix or a vector (bad upper bounds conditions in
1331: incrementation);
1332: - DISP intrinsic now uses the 33-th flag. When it is not set
1333: (default), a final carriage return is sent to the terminal;
1334: - AXES intrinsic only takes a list that can contains the keywork
1335: "main" or "auxiliary". Before this modification, this keyword was in
1336: the first stack level;
1337: - vim syntax file is upgraded;
1338: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1339: option;
1340: - LAST is now disabled in the main loop of INT intrinsic;
1341: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1342: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1343: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1344: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1345: in 0);
1346: - LAST is disabled in the main loop of DRAW intrinsic;
1347: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1348: evaluation of an equation, the system stack is returned corrupted to the
1349: sequencer;
1350: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1351: of a loop are not integer or real.
1352: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1360: - Makefile.am's and configure.in scripts are improved.
1361: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1362: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1363: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1364: the boxwidth, 1 by default);
1365: - recherche_type() is rewritten to be faster;
1366: - gsl is upgraded (release 1.3);
1367: - ncurses is upgraded and patched (release 5.3);

1381: - vim syntax file is improved;
1382: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1383: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1384: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1385: is a quick and dirty workaround...);
1386: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1387: - rplconvert is improved.

1496: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1497: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1498: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1499: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
