Annotation of rpl/ChangeLog, revision 1.46
1.45 bertrand 1: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
1.46 ! bertrand 2: - minor bug is fixed in data injection (POKE) that does not work as expected
! 3: when child process is protected by NRPROC.
1.44 bertrand 4: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 5: - --enable-sysv-sems is added to configure script to use SystemV semaphores
6: functions instead of POSIX functions. This function is disabled or forced on
7: systems that does not provide correct POSIX or SysV semaphores subsystem;
8: - a dirty but not quick patch is written to workaround broken siginfo
9: structures. This patch has been successfully tested. It uses a segment of
10: shared memory (SysV) and eleven semaphores (Posix or SysV) by process
11: (Unix PID);
1.41 bertrand 12: - some OpenBSD's hacks are added;
13: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 14: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
15: - random generator is cloned by SPAWN;
16: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
1.39 bertrand 17: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 18: or freeaddrinfo;
1.39 bertrand 19: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
20: - major bug is fixed in CHR intrinsic when obtained character is not printable;
21: - Lapack is upgraded to 3.2.2;
1.37 bertrand 22: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
1.36 bertrand 23: - TOKENIZE is now able to convert escape sequences;
24: - ATPOKE and CLRATPOKE new intrinsics are added;

26: postgresql libraries are statically linked in rpl executable;
27: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 28: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 29: - units is upgraded to 1.88;
30: - another major bug is fixed in the same variable creation subroutine.
31: Level 0 and 1 variables adresses were swapped when a global variable masked
32: a name of RPL/2 routine;
1.35 bertrand 33: - major bug is fixed in global variable creation subroutine. When a global
34: variable was created and when a local variable existed with the same name,
35: computed address of global variable was wrong;
36: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
37: is forced in front of all libraries.
1.34 bertrand 38: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
39: - BACKTRACE intrinsic is added;
40: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
41: when this structure is included in IFERR/THEN/END structure and when an error is
42: caught;
43: - major bug is fixed in analyse() subroutine. When evaluation() returned error
44: in a compiled program, analyse() caught this error twice and randomly aborted
45: with a segmentation error;
46: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
47: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
48: signals;
49: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
50: matrix.
1.33 bertrand 51: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

61: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
62: linux (false mremap() prototype);
63: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 64: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)

69: format in FCH (file descriptor) and SCK (socket descriptor);
70: - debug routines are improved;
71: - PROCID is added;
72: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
73: and to not use swap;
1.26 bertrand 74: - major bug is fixed in sql support. SQL connections were closed in all chield
75: process;
76: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
77: discovered in Solaris thread safe allocators (libmalloc and libumem) that
78: are first fit class allocators. Solaris libmtmalloc works better and is
79: a best fit class allocator but its performance is poor than ptmalloc3
80: performance;
1.24 bertrand 81: - major bug is fixed in ROW+ intrinsic (new row was not added where it
82: should);
83: - minor bugs are fixed in interruptions.c (semaphores values when error is
84: caught);
85: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
86: created by SPAWN;
87: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
88: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 89: - ONEXIT is renamed in ATEXIT;
90: - ONEXIT new intrinsic is added.
1.20 bertrand 91: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
92: - major bug is fixed in static and shared variables initialization subroutine.
93: This bug only occurs when RPL/2 tries to create a shared or static variable
94: from an expression;
95: - major bug is fixed in copie_etat_processus(). A field that contains
96: information about shared variable was not copied to new processus structure;
1.19 bertrand 97: - some little memory leaks are fixed in evaluation(), recherche_type() and
98: sequenceur(). They only occured when syntax error were caught;
99: - IMPLICIT causes execution error instead system error;
100: - Hurd support is improved but currently broken because Hurd does not support
101: SIG_INFO. Work in progress;
102: - OpenBSD specific support is removed from sources;
103: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 104: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)
105: - implicit names can now be disabled by new IMPLICIT intrinsic:

139: Makefiles;
1.15 bertrand 140: - -a command line option analyzes program (structure and syntax) and
141: sends preprocessor output to standard output. This option is used by
142: rplc (RPL/2 compiler).
1.13 bertrand 143: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
144: - in formatted file, string format returned a variable length string even if
145: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 146: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 147: - keyed access files support is added. Currently, only formatted files are
148: supported;

157: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
158: on a non recoverable system error;
159: - openssl and sqlite3 libraries are added;
160: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
161: variable indicates RPL/2 root directory. If it is not set, root path
162: is given by configure script (d_exec_path);
1.11 bertrand 163: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

188: Number of scalar operations per second and per core : 2383016
189:
190: - PULPRFL does not abort on BUG() but on execution error;
191: - TRIM, REPL and TOKENIZE are added;
192: - sockets options are now set before bind();
193: - shutdown() is added to all connected sockets;
194: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
195: list argument and inexistant elements).
196: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
197: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
198: signals sent to main process were not caught because DAEMON did not replace
199: old pid by new one;
200: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
201: evaluation when an error is reported from a subroutine in another subroutine.
202: For example, error was not caught in following program when it is executed with
203: -p option :
204: TEST << iferr TEST2 then end >>
205: TEST2 << 0 inv >>
206: - major bug is fixed in variable management. Some local variables were
207: seen as global ones;
208: - major bug is fixed in rplcore. Rplcore entered in dead lock when
209: script file contains a multibyte character;
210: - IN intrinsic is added;
211: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
212: returned false ;
213: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
214: programs;
215: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
216: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
217: strings were never closed;
218: - some bugs have been fixed in file management;
219: - RPL/2 can now be run on EBCDIC systems (OS/390);
220: - major bug is fixed in -A command line option (NULL character is missing);
221: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
222: made by blocks (1024 bytes). When an incomplete multibyte sequence is
223: encountered at end of block, subroutine aborts with an execution error;
224: - major bug is fixed in OPEN (TCP/IPv4 sockets).
225: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
226: - DISP now locks stdout;
227: - rpliconv is added to replace standard iconv provided by operating system.
228: Indeed, conversion between different encodages requires transliteration
229: that is not offered by some iconv utility;
230: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
231: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
232: not be found), SYSEVAL enters in a dead lock;
233: - fprintf is replaced by some functions that allow transliterations between
234: locales;
235: - '"' can now be used in strings ("\"");
236: - iconv is called with -c in preprocessor stage. It is done to write
237: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
238: - double free is fixed in liberation() (type SQL, only occurs when locale is
239: set);
240: - LOCALIZATION, UCASE and LCASE are added;
241: - major bug is fixed in EXIT intrinsic that was able to return a false
242: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
243: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
244: used in onLoading from shared library, USE was pushed on stack as algebraic
245: expression;
246: - libiconv is upgraded to 1.13.1;
247: - gnuplot is upgraded to 4.2.6;
248: - gsl is upgraded to 1.13.
249: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
250: - pipe() is overwritten by a macro to avoid a system error. Communication
251: between process are done with pipes and these pipes are managed by a
252: specific asynchrone thread. If a script try to create more threads than
253: management thread can destroy, you can quickly achieve maximum number of
254: opened files and pipe() shall return a system error. This macro tries to create
255: pipes. If pipe() function returns an error, macro waits and retries. If
256: number of retries is greater than a hardcoded value, macro returns an error;
257: - major bug (deadlock) is fixed in process and thread management. I hope
258: this bug shall be the last one;
259: - major bug is fixed in DET intrinsic (determinant was computed without LU
260: diagonalization);
261: - SWAPCNTXT is added;
262: - minor bug is fixed in Makefile.am (licences rule).
263: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
264: - some bugfixes are added in process management;
265: - all process management is rewritten to avoid usage of defunct process
266: or thread number;
267: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
268: was called before a pending interruption5 (SIGFSTOP), signal handler uses
269: a freed semaphore and corrupts heap;
270: - CLRERR is added to erase previous errors;
271: - ERRN and ERRM return exception message and number;
272: - major bug is fixed in interruptions.c. All signal are now bufferised
273: when semaphore_liste_threads is null to avoid deadlock. This bug only
274: occured when STOP was sent to a dying thread or process (when this thread or
275: process was running retrait_thread());
276: - matrix rank is computed before matrix inversion;
277: - file locks are added to stdin and stdout. stderr is not locked because
278: all messages written by signal handlers are sent to stderr;
279: - configure.in script is modified to test gcc version and avoid a bug in
280: gcc older than 4.4;
281: - some benchmarks have been done :

337: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
338: - FORTRAN 77 file management subroutines are rewritten in pure C due to
339: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
340: in some cases (gcc/gfortran/libc/OS and arch conjonction);
341: - a memory leak is fixed in REMOVE intrinsic;
342: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()

348: when SQL support was not enabled;
349: - new allocator is written for system stack and last stack;
350: - --enable-profile flag is added to configure script. When this flag is
351: enabled, rpl is built with -pg option;
352: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
353: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
354: process is killed;
355: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
356: know typeof() intrinsic function. This function is not standard but exists
357: under Sun Studio, gcc, and maybe some others compilers. If this function does
358: not exist on your compiler, you can change its definition by old one in
359: src/rpl.h;
360: - fflush() can now be interrupted by signal (SunOS);

381: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
382: deadlock when a huge amount of threads is launched);
383: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
384: arguments types are unsupported;
385: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
386: data are buffered. PLOT is used to draw these objects.);
387: - MARK instrinsic is added;

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

421: that all programs that worked with old SQL intrinsic can now work with
422: SQLQUERY. With all new programs, you can open a real connection to databases;
423: - NRPROC is added. This new intrinsic is used to catch error from child
424: process. Without NRPROC, any errors returned by child process cause
425: main process to abort;
426: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
427: starts a new process). There are no mutexes in RPL/2 because all spawned process
428: use specific context. Nevertheless, shared variables and associated mutexes
429: should be added;
430: - -D flag and DAEMONIZE intrinsic have been added;
431: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

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

578: - -p option is added. With this option, all scripts are compiled before
579: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
580: 40% faster;
581: - read and write operations in pipe() are rewritten to be sure that such
582: operations are atomic;
583: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

724: - external wrapper (rplplot) is written to force usage of gnuplot provided
725: by RPL/2 if it is built during build process. If this build does not exist,
726: it tries to launch regular gnuplot;
727: - gnuplot is added to source tree to avoid some trouble between preinstalled
728: gnuplot and release used by RPL/2. This addition to source tree is
729: required by some incompatibility between gnuplot releases;
730: - Lapack is upgraded to 3.1.1 release;
731: - GSL is upgraded to 1.9 revision;

1163: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1164: - SLICESCALE intrinsic is added. Its syntax is
1165: { "automatic" nb_of_levels }
1166: { "discrete" l1 l2 l3 ... }
1167: { "incremental" start incr }
1168: { "incremental" start incr end }
1169: { "automatic" } (default);
1170: - a minor bug (in last stack) is fixed in AXES intrinsic
1171: - flag 52 is used to automatically update graphics;
1172: - man pages are updated;
1173: - evaluation() is modified to perform evaluation of expressions that contain
1174: '=';
1175: - a minor bug is fixed in AXES intrinsic;
1176: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1177: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1178: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1179: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1180: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1196: - SCLS is added;
1197: - DRWS now uses COLS to draw 2D graphics;
1198: - PPAR and SPAR are written. SPAR returns a list that contains the
1199: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1200: statistical variable, or "DISABLED" if its type is not one of the type of
1201: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1202: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1203: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1204: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1205: disabled. Arguments of EXTERNAL are case sensitive because the external
1206: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1207: of known external functions but add the new list to the last. { "all" }
1208: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1209: external names of the known functions;
1210: - mkrplso.in is modified.
1211: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1212: - vim syntax file is upgraded;
1213: - a minor mistake is fixed in recherche_instruction_suivante();
1214: - some minor memory leaks are fixed in recherche_type() function. They only

1222: - PUTC and PUTR new intrinsics are added.
1223: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1224: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1225: VISIT does not find a name in level 1;
1226: - configure.in script is modified to add a new test (--enable-debug
1227: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1228: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1229: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1230: 'MATRIX' { 2 2 3 } GETR;
1231: - LOGSCALE intrinsic is improved and now, it can be used as
1232: { "main" "auxiliary" X Y } LOGSCALE;
1233: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1234: same than AXES:
1235: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1236: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1237: { { -10 10 } "automatic" } SCALE.
1238: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1239: because it changes only the dimension of the screen. To have a logarithmic
1240: scale, you must use LOGSCALE intrinsic:
1241: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1242: screen on second scale;
1243: - { X X } autoscale and { Y Y } logscale are now invalid;
1244: - *D is added (depth multiplication, for 3D graphics);
1245: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1246: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1247: - a major bug is fixed in GETI instrinsic when it is used with a name
1248: that contains a matrix or a vector (bad upper bounds conditions in
1249: incrementation);
1250: - DISP intrinsic now uses the 33-th flag. When it is not set
1251: (default), a final carriage return is sent to the terminal;
1252: - AXES intrinsic only takes a list that can contains the keywork
1253: "main" or "auxiliary". Before this modification, this keyword was in
1254: the first stack level;
1255: - vim syntax file is upgraded;
1256: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1257: option;
1258: - LAST is now disabled in the main loop of INT intrinsic;
1259: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1260: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1261: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1262: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1263: in 0);
1264: - LAST is disabled in the main loop of DRAW intrinsic;
1265: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1266: evaluation of an equation, the system stack is returned corrupted to the
1267: sequencer;
1268: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1269: of a loop are not integer or real.
1270: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1280: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1281: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1301: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1302: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1303: is a quick and dirty workaround...);
1304: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1305: - rplconvert is improved.

1415: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1416: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1417: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1418:
1419: Newton:[~/rpl/rpl] > time make install
