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

77: sends preprocessor output to standard output. This option is used by
78: rplc (RPL/2 compiler).
79: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
80: - in formatted file, string format returned a variable length string even if
81: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
82: a variable length string and 'CHARACTER*(n)' a fixed length string;
83: - keyed access files support is added. Currently, only formatted files are
84: supported;
85: - direct access files support is added. Currenlty, these files can only be used
86: in formatted mode;
87: - virtual variables are now writte in UTF-8 and all special characters
88: in string are escaped;
89: - all formatted files are now converted into UTF-8;
90: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
91: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
92: each execution (md5 and sha1 sums) to enhance security. If one of these tools
93: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
94: on a non recoverable system error;
95: - openssl and sqlite3 libraries are added;
96: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
97: variable indicates RPL/2 root directory. If it is not set, root path
98: is given by configure script (d_exec_path);
99: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

132: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
133: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
134: signals sent to main process were not caught because DAEMON did not replace
135: old pid by new one;
136: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
137: evaluation when an error is reported from a subroutine in another subroutine.
138: For example, error was not caught in following program when it is executed with
139: -p option :
140: TEST << iferr TEST2 then end >>
141: TEST2 << 0 inv >>
142: - major bug is fixed in variable management. Some local variables were
143: seen as global ones;
144: - major bug is fixed in rplcore. Rplcore entered in dead lock when
145: script file contains a multibyte character;
146: - IN intrinsic is added;
147: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
148: returned false ;
149: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
150: programs;
151: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
152: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
153: strings were never closed;

156: - major bug is fixed in -A command line option (NULL character is missing);
157: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
158: made by blocks (1024 bytes). When an incomplete multibyte sequence is
159: encountered at end of block, subroutine aborts with an execution error;
160: - major bug is fixed in OPEN (TCP/IPv4 sockets).
161: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
162: - DISP now locks stdout;
163: - rpliconv is added to replace standard iconv provided by operating system.
164: Indeed, conversion between different encodages requires transliteration
165: that is not offered by some iconv utility;
166: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
167: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
168: not be found), SYSEVAL enters in a dead lock;
169: - fprintf is replaced by some functions that allow transliterations between
170: locales;
171: - '"' can now be used in strings ("\"");
172: - iconv is called with -c in preprocessor stage. It is done to write
173: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
174: - double free is fixed in liberation() (type SQL, only occurs when locale is
175: set);
176: - LOCALIZATION, UCASE and LCASE are added;
177: - major bug is fixed in EXIT intrinsic that was able to return a false
178: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);

183: - gnuplot is upgraded to 4.2.6;
184: - gsl is upgraded to 1.13.
185: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
186: - pipe() is overwritten by a macro to avoid a system error. Communication
187: between process are done with pipes and these pipes are managed by a
188: specific asynchrone thread. If a script try to create more threads than
189: management thread can destroy, you can quickly achieve maximum number of
190: opened files and pipe() shall return a system error. This macro tries to create
191: pipes. If pipe() function returns an error, macro waits and retries. If
192: number of retries is greater than a hardcoded value, macro returns an error;
193: - major bug (deadlock) is fixed in process and thread management. I hope
194: this bug shall be the last one;
195: - major bug is fixed in DET intrinsic (determinant was computed without LU
196: diagonalization);
197: - SWAPCNTXT is added;
198: - minor bug is fixed in Makefile.am (licences rule).

200: - some bugfixes are added in process management;
201: - all process management is rewritten to avoid usage of defunct process
202: or thread number;
203: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
204: was called before a pending interruption5 (SIGFSTOP), signal handler uses
205: a freed semaphore and corrupts heap;
206: - CLRERR is added to erase previous errors;
207: - ERRN and ERRM return exception message and number;
208: - major bug is fixed in interruptions.c. All signal are now bufferised
209: when semaphore_liste_threads is null to avoid deadlock. This bug only
210: occured when STOP was sent to a dying thread or process (when this thread or
211: process was running retrait_thread());
212: - matrix rank is computed before matrix inversion;
213: - file locks are added to stdin and stdout. stderr is not locked because
214: all messages written by signal handlers are sent to stderr;
215: - configure.in script is modified to test gcc version and avoid a bug in
216: gcc older than 4.4;
217: - some benchmarks have been done :

273: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
274: - FORTRAN 77 file management subroutines are rewritten in pure C due to
275: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
276: in some cases (gcc/gfortran/libc/OS and arch conjonction);
277: - a memory leak is fixed in REMOVE intrinsic;

286: - --enable-profile flag is added to configure script. When this flag is
287: enabled, rpl is built with -pg option;
288: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
289: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
290: process is killed;
291: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
292: know typeof() intrinsic function. This function is not standard but exists
293: under Sun Studio, gcc, and maybe some others compilers. If this function does
294: not exist on your compiler, you can change its definition by old one in
295: src/rpl.h;

336: static variable that is shared by multiple threads;
337: - '->' intrinsic is improved. All object copies have been avoided;
338: - -n flag is added to catch HUP signal. stderr and stdout are redirected
339: to a file, stdin is redirected to /dev/null when control process is killed;

356: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
357: that all programs that worked with old SQL intrinsic can now work with
358: SQLQUERY. With all new programs, you can open a real connection to databases;
359: - NRPROC is added. This new intrinsic is used to catch error from child
360: process. Without NRPROC, any errors returned by child process cause
361: main process to abort;
362: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
363: starts a new process). There are no mutexes in RPL/2 because all spawned process
364: use specific context. Nevertheless, shared variables and associated mutexes
365: should be added;

713: With STATIC, next variables created by '->' are static;
714: - PROTECT and UNPROTECT are added to protect variables against write
715: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
716: versions of PROTECT and UNPROTECT that only deal with global variables
717: (see RCL/SAVE);
718: - variable management routines have been rewritten. The new ones are
719: uncompatible with the old ones. Before these changes, a local variable
720: was exported to a child subroutine, but cannot be modified into this
721: child subroutine. Now, a local variable is accessible only in its subroutine;
722: - SAVE intrinsic is added to manipulate global variables;

1162: - configure.in script is modified to add a new test (--enable-debug
1163: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1164: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1165: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1166: 'MATRIX' { 2 2 3 } GETR;
1167: - LOGSCALE intrinsic is improved and now, it can be used as
1168: { "main" "auxiliary" X Y } LOGSCALE;
1169: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1170: same than AXES:
1171: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1172: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1173: { { -10 10 } "automatic" } SCALE.
1174: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1175: because it changes only the dimension of the screen. To have a logarithmic
1176: scale, you must use LOGSCALE intrinsic:
1177: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1178: screen on second scale;
1179: - { X X } autoscale and { Y Y } logscale are now invalid;
1180: - *D is added (depth multiplication, for 3D graphics);
1181: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1182: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1183: - a major bug is fixed in GETI instrinsic when it is used with a name
1184: that contains a matrix or a vector (bad upper bounds conditions in
1185: incrementation);
1186: - DISP intrinsic now uses the 33-th flag. When it is not set
1187: (default), a final carriage return is sent to the terminal;
1188: - AXES intrinsic only takes a list that can contains the keywork
1189: "main" or "auxiliary". Before this modification, this keyword was in
1190: the first stack level;
1191: - vim syntax file is upgraded;
1192: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1193: option;
1194: - LAST is now disabled in the main loop of INT intrinsic;
1195: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1196: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1197: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1198: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1199: in 0);
1200: - LAST is disabled in the main loop of DRAW intrinsic;
1201: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1202: evaluation of an equation, the system stack is returned corrupted to the
1203: sequencer;
1204: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1205: of a loop are not integer or real.
1206: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1207: - the compilation stage aborts with an error message when two definitions
1208: have the same name. To improve the compilation() subroutine, I have to
1209: add some tests in gestion_variables.c;
1210: - recherche_type() subroutine ad some other connex subroutines are improved.
1211: Now, some syntax errors about object are caught and do not perform sequencer
1212: hangup;
1213: - readline is upgraded (minor compilation bug with recent gcc);
1214: - Makefile.am's and configure.in scripts are improved.
1215: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1216: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1217: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1218: the boxwidth, 1 by default);
1219: - recherche_type() is rewritten to be faster;
1220: - gsl is upgraded (release 1.3);
1221: - ncurses is upgraded and patched (release 5.3);
1222: - recherche_instruction_suivante() is fixed (string research with included
1223: '"') and rewritten to be faster;

1234: - a minor bug is fixed in evaluation subroutine;
1235: - vim syntax file is improved;
1236: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1237: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1238: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1239: is a quick and dirty workaround...);
1240: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1241: - rplconvert is improved.
1242: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
