Annotation of rpl/ChangeLog, revision 1.13
1.13 ! bertrand 1: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
! 2: - in formatted file, string format returned a variable length string even if
! 3: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
! 4: a variable length string and 'CHARACTER*(n') a fixed length string;
! 5: - keyed access files support is added. Currently, only formatted files are
! 6: supported;
! 7: - direct access files support is added. Currenlty, these files can only be used
! 8: in formatted mode;
! 9: - virtual variables are now writte in UTF-8 and all special characters
! 10: in string are escaped;
1.12 bertrand 11: - all formatted files are now converted into UTF-8;
12: - all file and unix socket names created by RPL/2 are now UTF8 compliant;
13: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
14: each execution (md5 and sha1 sums) to enhance security. If one of these tools
15: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
16: on a non recoverable system error;
17: - openssl and sqlite3 libraries are added;
18: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
19: variable indicates RPL/2 root directory. If it is not set, root path
20: is given by configure script (d_exec_path);
1.11 bertrand 21: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
22: - configure.in and makefile.am's are modified to add Cygwin support. Interix
23: support is broken;
1.10 bertrand 24: - memory leak is fixed in recherche_type();
25: - TeX files are now written in UTF-8 even default locale differs;
26: - minor bug is fixed in ->STR (escaped characters);
1.9 bertrand 27: - minor bug is fixed in ->Q intrinsic. Resultat is returned as integer
28: fraction intead real one;
29: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
1.8 bertrand 30: - Makefile.am are modified to authorize parallel builds;
1.7 bertrand 31: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
32: and writes warning to standard output;
1.6 bertrand 33: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)
1.5 bertrand 34: - escape codes are now converted in formateur(), not in recherche_type() to
35: avoid a minor bug in EDIT and VISIT intrinsics;
1.4 bertrand 36: - minor bug is fixed in formateur_reel();
1.7 bertrand 37: - file-5.03 is patched to avoid bus error on systems that require memory
1.3 bertrand 38: alignment;
1.2 bertrand 39: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
40: were able to be avoided by evaluation routine.
1.1 bertrand 41: * Tue Jan 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.9 (RPL/2)
42: - New benchmark on same hardware than old one :

46: Number of scalar operations per second and per core : 2383016
47:
48: - PULPRFL does not abort on BUG() but on execution error;
49: - TRIM, REPL and TOKENIZE are added;
50: - sockets options are now set before bind();
51: - shutdown() is added to all connected sockets;
52: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
53: list argument and inexistant elements).
54: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
55: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
56: signals sent to main process were not caught because DAEMON did not replace
57: old pid by new one;
58: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
59: evaluation when an error is reported from a subroutine in another subroutine.
60: For example, error was not caught in following program when it is executed with
61: -p option :
62: TEST << iferr TEST2 then end >>
63: TEST2 << 0 inv >>
64: - major bug is fixed in variable management. Some local variables were
65: seen as global ones;
66: - major bug is fixed in rplcore. Rplcore entered in dead lock when
67: script file contains a multibyte character;
68: - IN intrinsic is added;
69: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
70: returned false ;
71: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
72: programs;
73: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
74: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
75: strings were never closed;
76: - some bugs have been fixed in file management;
77: - RPL/2 can now be run on EBCDIC systems (OS/390);
78: - major bug is fixed in -A command line option (NULL character is missing);
79: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
80: made by blocks (1024 bytes). When an incomplete multibyte sequence is
81: encountered at end of block, subroutine aborts with an execution error;
82: - major bug is fixed in OPEN (TCP/IPv4 sockets).
83: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
84: - DISP now locks stdout;
85: - rpliconv is added to replace standard iconv provided by operating system.
86: Indeed, conversion between different encodages requires transliteration
87: that is not offered by some iconv utility;
88: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
89: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
90: not be found), SYSEVAL enters in a dead lock;
91: - fprintf is replaced by some functions that allow transliterations between
92: locales;
93: - '"' can now be used in strings ("\"");
94: - iconv is called with -c in preprocessor stage. It is done to write
95: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
96: - double free is fixed in liberation() (type SQL, only occurs when locale is
97: set);
98: - LOCALIZATION, UCASE and LCASE are added;
99: - major bug is fixed in EXIT intrinsic that was able to return a false
100: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
101: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
102: used in onLoading from shared library, USE was pushed on stack as algebraic
103: expression;
104: - libiconv is upgraded to 1.13.1;
105: - gnuplot is upgraded to 4.2.6;
106: - gsl is upgraded to 1.13.
107: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
108: - pipe() is overwritten by a macro to avoid a system error. Communication
109: between process are done with pipes and these pipes are managed by a
110: specific asynchrone thread. If a script try to create more threads than
111: management thread can destroy, you can quickly achieve maximum number of
112: opened files and pipe() shall return a system error. This macro tries to create
113: pipes. If pipe() function returns an error, macro waits and retries. If
114: number of retries is greater than a hardcoded value, macro returns an error;
115: - major bug (deadlock) is fixed in process and thread management. I hope
116: this bug shall be the last one;
117: - major bug is fixed in DET intrinsic (determinant was computed without LU
118: diagonalization);
119: - SWAPCNTXT is added;
120: - minor bug is fixed in Makefile.am (licences rule).
121: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
122: - some bugfixes are added in process management;
123: - all process management is rewritten to avoid usage of defunct process
124: or thread number;
125: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
126: was called before a pending interruption5 (SIGFSTOP), signal handler uses
127: a freed semaphore and corrupts heap;
128: - CLRERR is added to erase previous errors;
129: - ERRN and ERRM return exception message and number;
130: - major bug is fixed in interruptions.c. All signal are now bufferised
131: when semaphore_liste_threads is null to avoid deadlock. This bug only
132: occured when STOP was sent to a dying thread or process (when this thread or
133: process was running retrait_thread());
134: - matrix rank is computed before matrix inversion;
135: - file locks are added to stdin and stdout. stderr is not locked because
136: all messages written by signal handlers are sent to stderr;
137: - configure.in script is modified to test gcc version and avoid a bug in
138: gcc older than 4.4;
139: - some benchmarks have been done :

156: - SVL and SVD are added;
157: - COND and RANK are added;
158: - DIAG-> and ->DIAG are added;
159: - major bug is fixed in DET intrinsic. DET is rewritten to avoid usage of
160: eigenvalues. In a first time, matrix rank is estimated to force determinant
161: to zero if matrix is rank deficient. If not, a PLU decomposition is done to
162: compute determinant;
163: - QR matrix decomposition is added;
164: - LQ matrix decomposition is added;
165: - Fortran90 files are rewritten to use Fortran2003 bind(C) statement and

168: -Wno-unused-parameter;
169: - all mathematical exceptions are now signaled by exceptions instead of
170: execution error;
171: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
172: can call twice CSTOP without RSTOP;
173: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
174: SMPHRTRYDECR, SMPHGETV).
175: * Fri Jul 24 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.4 (RPL/2)
176: - semaphore is added in interruptions.c to avoid segmentation fault when STOP
177: signal is sent to a dying thread. Some mutexes are replaced by semaphores too
178: to be used in signal handlers;
179: - major bug (memory corruption) is fixed in COL- intrinsic;
180: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
181: software interrupt was caught;
182: - rplpp man page is added.
183: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
184: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
185: process termination);
186: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
187: its parent);
188: - a mutex to protect fork() syscall is added;
189: - all mutexes are unlocked after fork() in DETACH;
190: - minor bug (double free corruption) is fixed in CLOSE intrinsic;
191: - major bug is fixed in lecture_pipe when a nullified list is sent into a pipe;

193: - Level 0 variables are shared between all threads without copy. Indeed,
194: there variables are not modifiable and only contains static user definitions;
195: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
196: - FORTRAN 77 file management subroutines are rewritten in pure C due to
197: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
198: in some cases (gcc/gfortran/libc/OS and arch conjonction);
199: - a memory leak is fixed in REMOVE intrinsic;
200: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
201: and due to a libmysqlclient that is not thread safe).
202: * Wen Jun 10 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.2 (RPL/2)
203: - new enhanced allocator is written for regular variables, static variables and
204: shared variables;
205: - major bug is fixed in src/interruptions.c. This file did not compile
206: when SQL support was not enabled;
207: - new allocator is written for system stack and last stack;
208: - --enable-profile flag is added to configure script. When this flag is
209: enabled, rpl is built with -pg option;
210: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
211: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
212: process is killed;
213: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
214: know typeof() intrinsic function. This function is not standard but exists
215: under Sun Studio, gcc, and maybe some others compilers. If this function does
216: not exist on your compiler, you can change its definition by old one in
217: src/rpl.h;
218: - fflush() can now be interrupted by signal (SunOS);
219: - fflush(NULL) is called before all fork() occurrences;
220: - generators returned by RDGN help are sorted;

229: - code analysis is rewritten from scratch to be more efficient and mode
230: expandable;

232: that can returns a nullified siginfo pointer when SIGINT is sent by kernel
233: keyboard driver;
234: - gnuplot is now 4.2.5;
235: - readline is upgraded to 6.0;

237: - Signal handlers are rewritten to send signal to main thread when a signal
238: is send from an external process;
239: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
240: deadlock when a huge amount of threads is launched);
241: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
242: arguments types are unsupported;
243: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
244: data are buffered. PLOT is used to draw these objects.);
245: - MARK instrinsic is added;
246: - new allocator mechanism is written;
247: - some regression bugs have been fixed, some memory leaks too.
248: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)
249: - an estimation of future stack elements is added to avoid some costly memory

252: - RPL/2 can be built on Solaris 64 bits with some minor scripts alterations.
253: See README for more explanations;
254: - MTXSTATUS intrinsic is added;
255: - YIELD intrinsic is added;
256: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
257: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
258: static variable that is shared by multiple threads;
259: - '->' intrinsic is improved. All object copies have been avoided;
260: - -n flag is added to catch HUP signal. stderr and stdout are redirected
261: to a file, stdin is redirected to /dev/null when control process is killed;
262: - a mutex is added to each object (before this modification,
263: RPL/2 used a global mutex and performances in multithreaded programs were very
264: poor.);
265: - ALARM is now interruptible;
266: - both PUT and PUTI intrinsics are improved and do not copy list and table
267: when nombre_occurrences == 1;
268: - COPY intrinsic is added. Argument (that can be pointed from some objects)
269: is replaced by a new copy of itself;
270: - memory leak is fixed in sequenceur(). It only occurs when an execution error
271: is caught from interactive mode;

276: - new SQL type is added;
277: - due to a trouble in libpq in multithreaded context, SQL intrinsic is split
278: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
279: that all programs that worked with old SQL intrinsic can now work with
280: SQLQUERY. With all new programs, you can open a real connection to databases;
281: - NRPROC is added. This new intrinsic is used to catch error from child
282: process. Without NRPROC, any errors returned by child process cause
283: main process to abort;
284: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
285: starts a new process). There are no mutexes in RPL/2 because all spawned process
286: use specific context. Nevertheless, shared variables and associated mutexes
287: should be added;
288: - -D flag and DAEMONIZE intrinsic have been added;
289: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

304: it's done. Data integrity is now respected during transmission (POKE, SEND and
305: SWI);
306: - ITRACE is added. This intrinsic is only used to debug internal structures and
307: should not be used in regular programs;
308: - SWISTATUS is written;
309: - WFACK is written;
310: - rplcore files are now able to handle compilation errors;

334: - configure script is modified to check mysql and postgresql libraries
335: on all standard locations. Tested and works on FreeBSD, Solaris and Linux
336: Debian;
337: - Tables are allowed in eval ( <[ 1 ]> 't' sto 't(1)' eval );
338: - ->TABLE and TABLE-> intrinsics are added;
339: - major bug is fixed in recherche_type(). Only occurs when rpl executes
340: precompiled scripts;

357: CRTAB new intrinsic creates a regular table. By default, all elements are
358: nullified lists;
359: - rplexternals.h is modified and improved;
360: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and
361: configure script.
362: * Mon Jun 23 2008 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.7 (RPL/2)
363: - libiconv is added (iconv library exists on some systems but implemantations

373: - FUSE, RFUSE and CLRFUSE have been added;
374: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
375: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
376: workaround for this major bug. Nevertheless, all others capabilities seems to
377: work fine;

401: - PSHCNTXT and PULCNTXT are added (PSHCNTXT pushes context on an
402: internal contexts stack, PULCNTXT pulls contexts from this internal stack).
403: Main usages of these intrinsics are in conjonction with IFERR or with
404: software interrupts;
405: - HEAD, TAIL and REVLIST intrinsics are added;

426: before starting interrupt evaluation;
427: - -f parameter is added when iconv is called;
428: - as old file program was bugged, a new option is added to configure script.
429: When configure is called with --disable-encoding-autodetection, make does not
430: try to detect source encoding. Please, do not use if RPL/2 can be built
431: without this option !
432: - new garbage collector (and more efficient) is written;
433: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
434: not support real time signals, RPL/2 cannot use multitasking functions;
435: - error returned by preprocessor are now catched by RPL/2;
436: - -p option is added. With this option, all scripts are compiled before
437: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
438: 40% faster;
439: - read and write operations in pipe() are rewritten to be sure that such
440: operations are atomic;
441: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

637: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
638: versions of PROTECT and UNPROTECT that only deal with global variables
639: (see RCL/SAVE);
640: - variable management routines have been rewritten. The new ones are
641: uncompatible with the old ones. Before these changes, a local variable
642: was exported to a child subroutine, but cannot be modified into this
643: child subroutine. Now, a local variable is accessible only in its subroutine;
644: - SAVE intrinsic is added to manipulate global variables;

965: fine...);
966: - NOT is not correctly formatted in formateur.c:
967: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
968: with a NOTZ function !
969: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1035: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1036: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1037: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1058: statistical variable, or "DISABLED" if its type is not one of the type of
1059: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1060: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1061: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1062: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1063: disabled. Arguments of EXTERNAL are case sensitive because the external
1064: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1065: of known external functions but add the new list to the last. { "all" }
1066: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1067: external names of the known functions;
1068: - mkrplso.in is modified.
1069: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1082: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1083: VISIT does not find a name in level 1;
1084: - configure.in script is modified to add a new test (--enable-debug
1085: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1086: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1087: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1088: 'MATRIX' { 2 2 3 } GETR;
1089: - LOGSCALE intrinsic is improved and now, it can be used as
1090: { "main" "auxiliary" X Y } LOGSCALE;
1091: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1092: same than AXES:
1093: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1094: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1095: { { -10 10 } "automatic" } SCALE.
1096: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1097: because it changes only the dimension of the screen. To have a logarithmic
1098: scale, you must use LOGSCALE intrinsic:
1099: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1100: screen on second scale;
1101: - { X X } autoscale and { Y Y } logscale are now invalid;
1102: - *D is added (depth multiplication, for 3D graphics);
1103: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1104: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1105: - a major bug is fixed in GETI instrinsic when it is used with a name
1106: that contains a matrix or a vector (bad upper bounds conditions in
1107: incrementation);
1108: - DISP intrinsic now uses the 33-th flag. When it is not set
1109: (default), a final carriage return is sent to the terminal;
1110: - AXES intrinsic only takes a list that can contains the keywork
1111: "main" or "auxiliary". Before this modification, this keyword was in
1112: the first stack level;
1113: - vim syntax file is upgraded;
1114: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1115: option;
1116: - LAST is now disabled in the main loop of INT intrinsic;
1117: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1118: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1119: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1120: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1121: in 0);
1122: - LAST is disabled in the main loop of DRAW intrinsic;
1123: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1124: evaluation of an equation, the system stack is returned corrupted to the
1125: sequencer;
1126: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1127: of a loop are not integer or real.
1128: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1130: have the same name. To improve the compilation() subroutine, I have to
1131: add some tests in gestion_variables.c;
1132: - recherche_type() subroutine ad some other connex subroutines are improved.
1133: Now, some syntax errors about object are caught and do not perform sequencer
1134: hangup;
1135: - readline is upgraded (minor compilation bug with recent gcc);
1136: - Makefile.am's and configure.in scripts are improved.
1137: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1138: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
