1: * Thu Dec 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
2: - Lapack is upgraded to 3.3.0;
3: - libumem is now default Solaris allocator;
4: - ncurses is upgraded;
5: - regression introduced bt 4.0.19 is fixed in signal management.
6: Interruption1() can be called from itself and raises bus error (on sparc) or
7: segmentation fault;
8: - sqlite is upgraded to 3.7.4;
9: - OpenSSL is upgraded to 1.0.0c;
10: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);
11: - characters are tested in recherche_type() to avoid names like '12+';
12: - sqlite is upgraded to 3.7.3;
13: - gnuplot is upgraded to 4.4.2 due to major bugs.
14: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
15: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
16: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
17: corruption. As internal memory management have been improved, a best fit
18: allocator like ptmalloc3 is not required anymore;
19: - gnuplot is upgraded to 4.4.1;
20: - deadlock is fixed in signal handlers: same mutex was used in standard
21: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
22: and signal handlers. A new signal handler specific mutex is added;
23: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
24: that has to be evaluated by ->NUM;
25: - rplfile build process is modify to be sure that rplfile is not modified
26: after rpl build stage (to be sure that rplfile checksum is not modified after
27: rpl compilation);
28: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
29: modified to remove yacc code and renamed;
30: - some workarounds have been written to not use buggy klibc SystemV IPCS.
31: ABORT now works on eComStation;
32: - sqlite is upgraded to 3.7.2;
33: - bug is fixed in software interrupts. When both process have different PID,
34: parent process was not interrupted if it is not group master process. To fix
35: this bug, SIGINJECT signal is not sent by child process but by control thread
36: in parent process;
37: - minor bug is fixed in data injection (POKE) that does not work as expected
38: when child process is protected by NRPROC.
39: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
40: - --enable-sysv-sems is added to configure script to use SystemV semaphores
41: functions instead of POSIX functions. This function is disabled or forced on
42: systems that does not provide correct POSIX or SysV semaphores subsystem;
43: - a dirty but not quick patch is written to workaround broken siginfo
44: structures. This patch has been successfully tested. It uses a segment of
45: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
46: (Unix PID);
47: - some OpenBSD's hacks are added;
48: - broken siginfo->si_pid field is now checked by configure script;
49: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
50: - random generator is cloned by SPAWN;

58: - TOKENIZE is now able to convert escape sequences;
59: - ATPOKE and CLRATPOKE new intrinsics are added;
60: - --enable-full-static configure flag is added. With this flag, mysql and
61: postgresql libraries are statically linked in rpl executable;
62: - units Makefile is modified to avoid readline and ncurses usages;
63: - sqlite is upgraded to 3.7.0.1;
64: - units is upgraded to 1.88;
65: - another major bug is fixed in the same variable creation subroutine.
66: Level 0 and 1 variables adresses were swapped when a global variable masked
67: a name of RPL/2 routine;
68: - major bug is fixed in global variable creation subroutine. When a global
69: variable was created and when a local variable existed with the same name,
70: computed address of global variable was wrong;
71: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
72: is forced in front of all libraries.
73: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
74: - BACKTRACE intrinsic is added;
75: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
76: when this structure is included in IFERR/THEN/END structure and when an error is
77: caught;
78: - major bug is fixed in analyse() subroutine. When evaluation() returned error
79: in a compiled program, analyse() caught this error twice and randomly aborted
80: with a segmentation error;
81: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
82: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
83: signals;
84: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
85: matrix.
86: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
87: - minor bug is fixed in evaluation() subroutine. With this patch, same program
88: returns same result with or without -p flag;
89: - ncurses 5.7 is upgraded to 20100619;
90: - openssl is upgraded to 1.0.0a;
91: - interrupt stacks are now FIFO instead of LIFO;

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

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

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

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

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

255: - major bug is fixed in -A command line option (NULL character is missing);
256: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
257: made by blocks (1024 bytes). When an incomplete multibyte sequence is
258: encountered at end of block, subroutine aborts with an execution error;
259: - major bug is fixed in OPEN (TCP/IPv4 sockets).
260: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
261: - DISP now locks stdout;
262: - rpliconv is added to replace standard iconv provided by operating system.
263: Indeed, conversion between different encodages requires transliteration
264: that is not offered by some iconv utility;
265: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
266: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
267: not be found), SYSEVAL enters in a dead lock;
268: - fprintf is replaced by some functions that allow transliterations between
269: locales;
270: - '"' can now be used in strings ("\"");
271: - iconv is called with -c in preprocessor stage. It is done to write
272: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
273: - double free is fixed in liberation() (type SQL, only occurs when locale is
274: set);
275: - LOCALIZATION, UCASE and LCASE are added;
276: - major bug is fixed in EXIT intrinsic that was able to return a false
277: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
278: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
279: used in onLoading from shared library, USE was pushed on stack as algebraic
280: expression;
281: - libiconv is upgraded to 1.13.1;
282: - gnuplot is upgraded to 4.2.6;
283: - gsl is upgraded to 1.13.
284: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
285: - pipe() is overwritten by a macro to avoid a system error. Communication
286: between process are done with pipes and these pipes are managed by a
287: specific asynchrone thread. If a script try to create more threads than
288: management thread can destroy, you can quickly achieve maximum number of
289: opened files and pipe() shall return a system error. This macro tries to create
290: pipes. If pipe() function returns an error, macro waits and retries. If
291: number of retries is greater than a hardcoded value, macro returns an error;
292: - major bug (deadlock) is fixed in process and thread management. I hope
293: this bug shall be the last one;
294: - major bug is fixed in DET intrinsic (determinant was computed without LU
295: diagonalization);
296: - SWAPCNTXT is added;
297: - minor bug is fixed in Makefile.am (licences rule).

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

372: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
373: - FORTRAN 77 file management subroutines are rewritten in pure C due to
374: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
375: in some cases (gcc/gfortran/libc/OS and arch conjonction);

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

761: it tries to launch regular gnuplot;
762: - gnuplot is added to source tree to avoid some trouble between preinstalled
763: gnuplot and release used by RPL/2. This addition to source tree is
764: required by some incompatibility between gnuplot releases;
765: - Lapack is upgraded to 3.1.1 release;
766: - GSL is upgraded to 1.9 revision;

789:
790: #!/usr/local/bin/rpl -sc
791:
792: TEST
793: <<
794: 1 1000 start VAR_S VAR_S2 next
795: >>
796:
797: VAR_S
798: <<
799: static 3 -> C << C disp 'C' incr if C 10 > then 'C' volatile end >>

1198: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1199: - SLICESCALE intrinsic is added. Its syntax is
1200: { "automatic" nb_of_levels }
1201: { "discrete" l1 l2 l3 ... }
1202: { "incremental" start incr }
1203: { "incremental" start incr end }
1204: { "automatic" } (default);
1205: - a minor bug (in last stack) is fixed in AXES intrinsic
1206: - flag 52 is used to automatically update graphics;
1207: - man pages are updated;
1208: - evaluation() is modified to perform evaluation of expressions that contain
1209: '=';
1210: - a minor bug is fixed in AXES intrinsic;
1211: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1212: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1213: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1214: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1215: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1231: - SCLS is added;
1232: - DRWS now uses COLS to draw 2D graphics;
1233: - PPAR and SPAR are written. SPAR returns a list that contains the
1234: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1235: statistical variable, or "DISABLED" if its type is not one of the type of
1236: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1237: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1238: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1239: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1240: disabled. Arguments of EXTERNAL are case sensitive because the external
1241: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1242: of known external functions but add the new list to the last. { "all" }
1243: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1244: external names of the known functions;
1245: - mkrplso.in is modified.
1246: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1247: - vim syntax file is upgraded;
1248: - a minor mistake is fixed in recherche_instruction_suivante();
1249: - some minor memory leaks are fixed in recherche_type() function. They only
1250: occurs when a syntax error is detected;

1256: - SCALE is fixed and improved ("automatic" keyword);
1257: - PUTC and PUTR new intrinsics are added.
1258: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1259: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1260: VISIT does not find a name in level 1;
1261: - configure.in script is modified to add a new test (--enable-debug
1262: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1263: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1264: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1265: 'MATRIX' { 2 2 3 } GETR;
1266: - LOGSCALE intrinsic is improved and now, it can be used as
1267: { "main" "auxiliary" X Y } LOGSCALE;
1268: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1269: same than AXES:
1270: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1271: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1272: { { -10 10 } "automatic" } SCALE.
1273: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1274: because it changes only the dimension of the screen. To have a logarithmic
1275: scale, you must use LOGSCALE intrinsic:
1276: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1277: screen on second scale;
1278: - { X X } autoscale and { Y Y } logscale are now invalid;
1279: - *D is added (depth multiplication, for 3D graphics);
1280: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1281: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1282: - a major bug is fixed in GETI instrinsic when it is used with a name
1283: that contains a matrix or a vector (bad upper bounds conditions in
1284: incrementation);
1285: - DISP intrinsic now uses the 33-th flag. When it is not set
1286: (default), a final carriage return is sent to the terminal;
1287: - AXES intrinsic only takes a list that can contains the keywork
1288: "main" or "auxiliary". Before this modification, this keyword was in
1289: the first stack level;
1290: - vim syntax file is upgraded;
1291: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1292: option;
1293: - LAST is now disabled in the main loop of INT intrinsic;
1294: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1295: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1296: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1297: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1298: in 0);
1299: - LAST is disabled in the main loop of DRAW intrinsic;
1300: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1301: evaluation of an equation, the system stack is returned corrupted to the
1302: sequencer;
1303: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1304: of a loop are not integer or real.
1305: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1306: - the compilation stage aborts with an error message when two definitions
1307: have the same name. To improve the compilation() subroutine, I have to
1308: add some tests in gestion_variables.c;
1309: - recherche_type() subroutine ad some other connex subroutines are improved.
1310: Now, some syntax errors about object are caught and do not perform sequencer
1311: hangup;

1313: - Makefile.am's and configure.in scripts are improved.
1314: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1315: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1316: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1317: the boxwidth, 1 by default);
1318: - recherche_type() is rewritten to be faster;
1319: - gsl is upgraded (release 1.3);
1320: - ncurses is upgraded and patched (release 5.3);
1321: - recherche_instruction_suivante() is fixed (string research with included
1322: '"') and rewritten to be faster;
1323: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1324: segfault.
1325: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1333: - a minor bug is fixed in evaluation subroutine;
1334: - vim syntax file is improved;
1335: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1336: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1337: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1338: is a quick and dirty workaround...);
1339: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1340: - rplconvert is improved.
1341: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1357: Now, an expression such as 'A+' returns an error when it is analyzed;
1358: - VISIT intrinsic is added;
1359: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1360: normal mode.

1448: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1449: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1450: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1451: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1452: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1453:
1454: Newton:[~/rpl/rpl] > time make install
1455: ...
1456: real 338m39.623s
1457: user 324m32.290s
