Annotation of rpl/ChangeLog, revision 1.27
1.26 bertrand 1: * Fri May 7 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.27 ! bertrand 2: - MEMLOCK and MEMUNLOCK are added. MEMLOCK force a process to not use swap;
1.26 bertrand 3: - major bug is fixed in sql support. SQL connections were closed in all chield
4: process;
5: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
6: discovered in Solaris thread safe allocators (libmalloc and libumem) that
7: are first fit class allocators. Solaris libmtmalloc works better and is
8: a best fit class allocator but its performance is poor than ptmalloc3
9: performance;
1.24 bertrand 10: - major bug is fixed in ROW+ intrinsic (new row was not added where it
11: should);
12: - minor bugs are fixed in interruptions.c (semaphores values when error is
13: caught);
14: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
15: created by SPAWN;
16: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
17: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 18: - ONEXIT is renamed in ATEXIT;
19: - ONEXIT new intrinsic is added.
1.20 bertrand 20: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
21: - major bug is fixed in static and shared variables initialization subroutine.
22: This bug only occurs when RPL/2 tries to create a shared or static variable
23: from an expression;
24: - major bug is fixed in copie_etat_processus(). A field that contains
25: information about shared variable was not copied to new processus structure;
1.19 bertrand 26: - some little memory leaks are fixed in evaluation(), recherche_type() and
27: sequenceur(). They only occured when syntax error were caught;
28: - IMPLICIT causes execution error instead system error;
29: - Hurd support is improved but currently broken because Hurd does not support
30: SIG_INFO. Work in progress;
31: - OpenBSD specific support is removed from sources;
32: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 33: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

61: By default, implicit is set to "ALL";
1.16 bertrand 62: - sqlite is upgraded to 3.6.23.1;
63: - openssl is upgraded to 1.0.0;
64: - major bug is fixed in RETURN intrinsic. It only occurs in evaluation
65: subroutine;
66: - table variable can now be sorted by SORT;
67: - some regressions between libtool 1.x and 2.x are fixed by workarouds in
68: Makefiles;
1.15 bertrand 69: - -a command line option analyzes program (structure and syntax) and
70: sends preprocessor output to standard output. This option is used by
71: rplc (RPL/2 compiler).
1.13 bertrand 72: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
73: - in formatted file, string format returned a variable length string even if
74: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 75: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 76: - keyed access files support is added. Currently, only formatted files are
77: supported;
78: - direct access files support is added. Currenlty, these files can only be used
79: in formatted mode;
80: - virtual variables are now writte in UTF-8 and all special characters
81: in string are escaped;
1.12 bertrand 82: - all formatted files are now converted into UTF-8;
1.17 bertrand 83: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
1.12 bertrand 84: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
85: each execution (md5 and sha1 sums) to enhance security. If one of these tools
86: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
87: on a non recoverable system error;
88: - openssl and sqlite3 libraries are added;
89: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
90: variable indicates RPL/2 root directory. If it is not set, root path
91: is given by configure script (d_exec_path);
1.11 bertrand 92: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
93: - configure.in and makefile.am's are modified to add Cygwin support. Interix

96: - TeX files are now written in UTF-8 even default locale differs;
97: - minor bug is fixed in ->STR (escaped characters);
1.9 bertrand 98: - minor bug is fixed in ->Q intrinsic. Resultat is returned as integer
99: fraction intead real one;
100: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
1.8 bertrand 101: - Makefile.am are modified to authorize parallel builds;
1.7 bertrand 102: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
103: and writes warning to standard output;

106: avoid a minor bug in EDIT and VISIT intrinsics;
1.4 bertrand 107: - minor bug is fixed in formateur_reel();
1.7 bertrand 108: - file-5.03 is patched to avoid bus error on systems that require memory
1.3 bertrand 109: alignment;
1.2 bertrand 110: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
111: were able to be avoided by evaluation routine.
1.1 bertrand 112: * Tue Jan 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.9 (RPL/2)

117: Number of scalar operations per second and per core : 2383016
118:
119: - PULPRFL does not abort on BUG() but on execution error;
120: - TRIM, REPL and TOKENIZE are added;
121: - sockets options are now set before bind();
122: - shutdown() is added to all connected sockets;
123: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
124: list argument and inexistant elements).
125: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
126: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
127: signals sent to main process were not caught because DAEMON did not replace
128: old pid by new one;
129: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
130: evaluation when an error is reported from a subroutine in another subroutine.
131: For example, error was not caught in following program when it is executed with
132: -p option :
133: TEST << iferr TEST2 then end >>
134: TEST2 << 0 inv >>
135: - major bug is fixed in variable management. Some local variables were
136: seen as global ones;
137: - major bug is fixed in rplcore. Rplcore entered in dead lock when
138: script file contains a multibyte character;
139: - IN intrinsic is added;
140: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
141: returned false ;
142: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
143: programs;
144: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
145: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
146: strings were never closed;
147: - some bugs have been fixed in file management;
148: - RPL/2 can now be run on EBCDIC systems (OS/390);
149: - major bug is fixed in -A command line option (NULL character is missing);
150: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
151: made by blocks (1024 bytes). When an incomplete multibyte sequence is
152: encountered at end of block, subroutine aborts with an execution error;
153: - major bug is fixed in OPEN (TCP/IPv4 sockets).
154: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
155: - DISP now locks stdout;
156: - rpliconv is added to replace standard iconv provided by operating system.
157: Indeed, conversion between different encodages requires transliteration
158: that is not offered by some iconv utility;
159: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
160: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
161: not be found), SYSEVAL enters in a dead lock;
162: - fprintf is replaced by some functions that allow transliterations between
163: locales;
164: - '"' can now be used in strings ("\"");
165: - iconv is called with -c in preprocessor stage. It is done to write
166: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
167: - double free is fixed in liberation() (type SQL, only occurs when locale is
168: set);
169: - LOCALIZATION, UCASE and LCASE are added;
170: - major bug is fixed in EXIT intrinsic that was able to return a false
171: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
172: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
173: used in onLoading from shared library, USE was pushed on stack as algebraic
174: expression;
175: - libiconv is upgraded to 1.13.1;
176: - gnuplot is upgraded to 4.2.6;
177: - gsl is upgraded to 1.13.
178: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
179: - pipe() is overwritten by a macro to avoid a system error. Communication
180: between process are done with pipes and these pipes are managed by a
181: specific asynchrone thread. If a script try to create more threads than
182: management thread can destroy, you can quickly achieve maximum number of
183: opened files and pipe() shall return a system error. This macro tries to create
184: pipes. If pipe() function returns an error, macro waits and retries. If
185: number of retries is greater than a hardcoded value, macro returns an error;
186: - major bug (deadlock) is fixed in process and thread management. I hope
187: this bug shall be the last one;
188: - major bug is fixed in DET intrinsic (determinant was computed without LU
189: diagonalization);
190: - SWAPCNTXT is added;
191: - minor bug is fixed in Makefile.am (licences rule).
192: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
193: - some bugfixes are added in process management;
194: - all process management is rewritten to avoid usage of defunct process
195: or thread number;
196: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
197: was called before a pending interruption5 (SIGFSTOP), signal handler uses
198: a freed semaphore and corrupts heap;
199: - CLRERR is added to erase previous errors;
200: - ERRN and ERRM return exception message and number;
201: - major bug is fixed in interruptions.c. All signal are now bufferised
202: when semaphore_liste_threads is null to avoid deadlock. This bug only
203: occured when STOP was sent to a dying thread or process (when this thread or
204: process was running retrait_thread());
205: - matrix rank is computed before matrix inversion;
206: - file locks are added to stdin and stdout. stderr is not locked because
207: all messages written by signal handlers are sent to stderr;
208: - configure.in script is modified to test gcc version and avoid a bug in
209: gcc older than 4.4;
210: - some benchmarks have been done :

229: - DIAG-> and ->DIAG are added;
230: - major bug is fixed in DET intrinsic. DET is rewritten to avoid usage of
231: eigenvalues. In a first time, matrix rank is estimated to force determinant
232: to zero if matrix is rank deficient. If not, a PLU decomposition is done to
233: compute determinant;
234: - QR matrix decomposition is added;
235: - LQ matrix decomposition is added;
236: - Fortran90 files are rewritten to use Fortran2003 bind(C) statement and

239: -Wno-unused-parameter;
240: - all mathematical exceptions are now signaled by exceptions instead of
241: execution error;
242: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
243: can call twice CSTOP without RSTOP;
244: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
245: SMPHRTRYDECR, SMPHGETV).
246: * Fri Jul 24 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.4 (RPL/2)
247: - semaphore is added in interruptions.c to avoid segmentation fault when STOP
248: signal is sent to a dying thread. Some mutexes are replaced by semaphores too
249: to be used in signal handlers;
250: - major bug (memory corruption) is fixed in COL- intrinsic;
251: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
252: software interrupt was caught;
253: - rplpp man page is added.
254: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
255: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
256: process termination);
257: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
258: its parent);
259: - a mutex to protect fork() syscall is added;
260: - all mutexes are unlocked after fork() in DETACH;
261: - minor bug (double free corruption) is fixed in CLOSE intrinsic;
262: - major bug is fixed in lecture_pipe when a nullified list is sent into a pipe;
263: - WORKDIR intrinsic is added;
264: - Level 0 variables are shared between all threads without copy. Indeed,
265: there variables are not modifiable and only contains static user definitions;
266: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
267: - FORTRAN 77 file management subroutines are rewritten in pure C due to
268: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
269: in some cases (gcc/gfortran/libc/OS and arch conjonction);
270: - a memory leak is fixed in REMOVE intrinsic;
271: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
272: and due to a libmysqlclient that is not thread safe).
273: * Wen Jun 10 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.2 (RPL/2)
274: - new enhanced allocator is written for regular variables, static variables and
275: shared variables;
276: - major bug is fixed in src/interruptions.c. This file did not compile
277: when SQL support was not enabled;
278: - new allocator is written for system stack and last stack;
279: - --enable-profile flag is added to configure script. When this flag is
280: enabled, rpl is built with -pg option;
281: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
282: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
283: process is killed;
284: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
285: know typeof() intrinsic function. This function is not standard but exists
286: under Sun Studio, gcc, and maybe some others compilers. If this function does
287: not exist on your compiler, you can change its definition by old one in
288: src/rpl.h;
289: - fflush() can now be interrupted by signal (SunOS);
290: - fflush(NULL) is called before all fork() occurrences;
291: - generators returned by RDGN help are sorted;

308: - Signal handlers are rewritten to send signal to main thread when a signal
309: is send from an external process;
310: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
311: deadlock when a huge amount of threads is launched);
312: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
313: arguments types are unsupported;
314: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

318: - some regression bugs have been fixed, some memory leaks too.
319: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)
320: - an estimation of future stack elements is added to avoid some costly memory
321: allocations. This function has a positive impact on execution speed;
322: - PSHPRFL and PULPRFL have been added;
323: - RPL/2 can be built on Solaris 64 bits with some minor scripts alterations.
324: See README for more explanations;
325: - MTXSTATUS intrinsic is added;
326: - YIELD intrinsic is added;
327: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
328: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
329: static variable that is shared by multiple threads;
330: - '->' intrinsic is improved. All object copies have been avoided;
331: - -n flag is added to catch HUP signal. stderr and stdout are redirected
332: to a file, stdin is redirected to /dev/null when control process is killed;
333: - a mutex is added to each object (before this modification,
334: RPL/2 used a global mutex and performances in multithreaded programs were very
335: poor.);
336: - ALARM is now interruptible;
337: - both PUT and PUTI intrinsics are improved and do not copy list and table
338: when nombre_occurrences == 1;

345: - profile statistics have been added. See -P option;
346: - major bug is fixed in analyse_syntaxique();
347: - new SQL type is added;
348: - due to a trouble in libpq in multithreaded context, SQL intrinsic is split
349: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
350: that all programs that worked with old SQL intrinsic can now work with
351: SQLQUERY. With all new programs, you can open a real connection to databases;
352: - NRPROC is added. This new intrinsic is used to catch error from child
353: process. Without NRPROC, any errors returned by child process cause
354: main process to abort;
355: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
356: starts a new process). There are no mutexes in RPL/2 because all spawned process
357: use specific context. Nevertheless, shared variables and associated mutexes
358: should be added;
359: - -D flag and DAEMONIZE intrinsic have been added;
360: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;
361: - autoconf script is modified to handle mysql and postgresql on non standard
362: directories;

365: getpid() can return (pid_t) -1 or (pid_t) -2 value;
366: - major bug is fixed in REPEAT intrinsic. Only occurs in compiled mode;
367: - all but jump variables are removed from source. All signal handlers now
368: use encapsulated variables and signals are caught by thread;

370: - NEWPLANE is added;
371: - LINE is added;
372: - DGTIZ is added;
373: - major bug is fixed in ROW-> intrinsic (comes from new garbage collector);

375: it's done. Data integrity is now respected during transmission (POKE, SEND and
376: SWI);
377: - ITRACE is added. This intrinsic is only used to debug internal structures and
378: should not be used in regular programs;
379: - SWISTATUS is written;
380: - WFACK is written;
381: - rplcore files are now able to handle compilation errors;
382: - rplcore files are now able to handle evaluation and interruption errors;
383: - SORT can now be used on table;
384: - tables can now be sent by POKE and SEND instrinsics;
385: - software interrupts do not inherit IFERR controls;
386: - LOGGER intrinsic is added;
387: - All WF* intrinsics but WFSOCK are made interruptible;
388: - ISWI intrinsic is added. Current interrupt is marked as 'interruptible';
389: - tables can be used with SAME intrinsic;
390: - minor bug is fixed in recherche_variable(). Only occurs when an error
391: is caught;

1153: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1154: VISIT does not find a name in level 1;
1155: - configure.in script is modified to add a new test (--enable-debug
1156: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1157: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1158: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1159: 'MATRIX' { 2 2 3 } GETR;
1160: - LOGSCALE intrinsic is improved and now, it can be used as
1161: { "main" "auxiliary" X Y } LOGSCALE;
1162: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1163: same than AXES:
1164: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1165: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1166: { { -10 10 } "automatic" } SCALE.
1167: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1168: because it changes only the dimension of the screen. To have a logarithmic
1169: scale, you must use LOGSCALE intrinsic:
1170: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1171: screen on second scale;
1172: - { X X } autoscale and { Y Y } logscale are now invalid;
1173: - *D is added (depth multiplication, for 3D graphics);
1174: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1175: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1176: - a major bug is fixed in GETI instrinsic when it is used with a name
1177: that contains a matrix or a vector (bad upper bounds conditions in
1178: incrementation);
1179: - DISP intrinsic now uses the 33-th flag. When it is not set
1180: (default), a final carriage return is sent to the terminal;
1181: - AXES intrinsic only takes a list that can contains the keywork
1182: "main" or "auxiliary". Before this modification, this keyword was in
1183: the first stack level;
1184: - vim syntax file is upgraded;
1185: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1186: option;
1187: - LAST is now disabled in the main loop of INT intrinsic;
1188: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1189: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1190: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1191: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1192: in 0);
1193: - LAST is disabled in the main loop of DRAW intrinsic;
1194: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1195: evaluation of an equation, the system stack is returned corrupted to the
1196: sequencer;
1197: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1198: of a loop are not integer or real.
1199: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1200: - the compilation stage aborts with an error message when two definitions
1201: have the same name. To improve the compilation() subroutine, I have to
1202: add some tests in gestion_variables.c;
1203: - recherche_type() subroutine ad some other connex subroutines are improved.
1204: Now, some syntax errors about object are caught and do not perform sequencer
1205: hangup;
1206: - readline is upgraded (minor compilation bug with recent gcc);
1207: - Makefile.am's and configure.in scripts are improved.
1208: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1209: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1210: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1211: the boxwidth, 1 by default);
1212: - recherche_type() is rewritten to be faster;
1213: - gsl is upgraded (release 1.3);
1214: - ncurses is upgraded and patched (release 5.3);
1215: - recherche_instruction_suivante() is fixed (string research with included
1216: '"') and rewritten to be faster;

1227: - a minor bug is fixed in evaluation subroutine;
1228: - vim syntax file is improved;
1229: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1230: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1231: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1232: is a quick and dirty workaround...);
1233: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1234: - rplconvert is improved.
1235: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1345: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1346: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1347:
1348: Newton:[~/rpl/rpl] > time make install
