2: - major bug is fixed in static and shared variables initialization subroutine.
3: This bug only occurs when RPL/2 tries to create a shared or static variable
4: from an expression;
5: - major bug is fixed in copie_etat_processus(). A field that contains
6: information about shared variable was not copied to new processus structure;
7: - some little memory leaks are fixed in evaluation(), recherche_type() and
8: sequenceur(). They only occured when syntax error were caught;
9: - IMPLICIT causes execution error instead system error;
10: - Hurd support is improved but currently broken because Hurd does not support
11: SIG_INFO. Work in progress;
12: - OpenBSD specific support is removed from sources;
13: - support for Mac OS X and Windows/Cygwin is added.
14: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

43: - sqlite is upgraded to 3.6.23.1;
44: - openssl is upgraded to 1.0.0;
45: - major bug is fixed in RETURN intrinsic. It only occurs in evaluation
46: subroutine;

49: Makefiles;
50: - -a command line option analyzes program (structure and syntax) and
51: sends preprocessor output to standard output. This option is used by
52: rplc (RPL/2 compiler).
53: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
54: - in formatted file, string format returned a variable length string even if
55: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
56: a variable length string and 'CHARACTER*(n)' a fixed length string;
57: - keyed access files support is added. Currently, only formatted files are
58: supported;
59: - direct access files support is added. Currenlty, these files can only be used
60: in formatted mode;
61: - virtual variables are now writte in UTF-8 and all special characters
62: in string are escaped;
63: - all formatted files are now converted into UTF-8;
64: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
65: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
66: each execution (md5 and sha1 sums) to enhance security. If one of these tools
67: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
68: on a non recoverable system error;
69: - openssl and sqlite3 libraries are added;
70: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
71: variable indicates RPL/2 root directory. If it is not set, root path
72: is given by configure script (d_exec_path);
73: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

81: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
82: - Makefile.am are modified to authorize parallel builds;
83: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
84: and writes warning to standard output;
85: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)
86: - escape codes are now converted in formateur(), not in recherche_type() to

89: - file-5.03 is patched to avoid bus error on systems that require memory
90: alignment;
91: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
92: were able to be avoided by evaluation routine.

106: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
107: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
108: signals sent to main process were not caught because DAEMON did not replace
109: old pid by new one;
110: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
111: evaluation when an error is reported from a subroutine in another subroutine.
112: For example, error was not caught in following program when it is executed with
113: -p option :
114: TEST << iferr TEST2 then end >>
115: TEST2 << 0 inv >>
116: - major bug is fixed in variable management. Some local variables were
117: seen as global ones;
118: - major bug is fixed in rplcore. Rplcore entered in dead lock when
119: script file contains a multibyte character;
120: - IN intrinsic is added;
121: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
122: returned false ;
123: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
124: programs;
125: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
126: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
127: strings were never closed;

130: - major bug is fixed in -A command line option (NULL character is missing);
131: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
132: made by blocks (1024 bytes). When an incomplete multibyte sequence is
133: encountered at end of block, subroutine aborts with an execution error;
134: - major bug is fixed in OPEN (TCP/IPv4 sockets).
135: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
136: - DISP now locks stdout;
137: - rpliconv is added to replace standard iconv provided by operating system.
138: Indeed, conversion between different encodages requires transliteration
139: that is not offered by some iconv utility;
140: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
141: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
142: not be found), SYSEVAL enters in a dead lock;
143: - fprintf is replaced by some functions that allow transliterations between
144: locales;
145: - '"' can now be used in strings ("\"");
146: - iconv is called with -c in preprocessor stage. It is done to write
147: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
148: - double free is fixed in liberation() (type SQL, only occurs when locale is
149: set);
150: - LOCALIZATION, UCASE and LCASE are added;
151: - major bug is fixed in EXIT intrinsic that was able to return a false
152: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
153: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
154: used in onLoading from shared library, USE was pushed on stack as algebraic
155: expression;

157: - gnuplot is upgraded to 4.2.6;
158: - gsl is upgraded to 1.13.
159: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
160: - pipe() is overwritten by a macro to avoid a system error. Communication
161: between process are done with pipes and these pipes are managed by a
162: specific asynchrone thread. If a script try to create more threads than
163: management thread can destroy, you can quickly achieve maximum number of
164: opened files and pipe() shall return a system error. This macro tries to create
165: pipes. If pipe() function returns an error, macro waits and retries. If
166: number of retries is greater than a hardcoded value, macro returns an error;
167: - major bug (deadlock) is fixed in process and thread management. I hope
168: this bug shall be the last one;
169: - major bug is fixed in DET intrinsic (determinant was computed without LU
170: diagonalization);
171: - SWAPCNTXT is added;
172: - minor bug is fixed in Makefile.am (licences rule).
173: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
174: - some bugfixes are added in process management;
175: - all process management is rewritten to avoid usage of defunct process
176: or thread number;
177: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
178: was called before a pending interruption5 (SIGFSTOP), signal handler uses
179: a freed semaphore and corrupts heap;
180: - CLRERR is added to erase previous errors;
181: - ERRN and ERRM return exception message and number;
182: - major bug is fixed in interruptions.c. All signal are now bufferised
183: when semaphore_liste_threads is null to avoid deadlock. This bug only
184: occured when STOP was sent to a dying thread or process (when this thread or
185: process was running retrait_thread());
186: - matrix rank is computed before matrix inversion;
187: - file locks are added to stdin and stdout. stderr is not locked because
188: all messages written by signal handlers are sent to stderr;
189: - configure.in script is modified to test gcc version and avoid a bug in
190: gcc older than 4.4;
191: - some benchmarks have been done :

263: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
264: process is killed;
265: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
266: know typeof() intrinsic function. This function is not standard but exists
267: under Sun Studio, gcc, and maybe some others compilers. If this function does
268: not exist on your compiler, you can change its definition by old one in

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

331: that all programs that worked with old SQL intrinsic can now work with
332: SQLQUERY. With all new programs, you can open a real connection to databases;
333: - NRPROC is added. This new intrinsic is used to catch error from child
334: process. Without NRPROC, any errors returned by child process cause
335: main process to abort;
336: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
337: starts a new process). There are no mutexes in RPL/2 because all spawned process
338: use specific context. Nevertheless, shared variables and associated mutexes
339: should be added;

687: With STATIC, next variables created by '->' are static;
688: - PROTECT and UNPROTECT are added to protect variables against write
689: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
690: versions of PROTECT and UNPROTECT that only deal with global variables
691: (see RCL/SAVE);
692: - variable management routines have been rewritten. The new ones are
693: uncompatible with the old ones. Before these changes, a local variable
694: was exported to a child subroutine, but cannot be modified into this
695: child subroutine. Now, a local variable is accessible only in its subroutine;
696: - SAVE intrinsic is added to manipulate global variables;

1018: - NOT is not correctly formatted in formateur.c:
1019: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1020: with a NOTZ function !
1021: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1107: - DRWS now uses COLS to draw 2D graphics;
1108: - PPAR and SPAR are written. SPAR returns a list that contains the
1109: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1110: statistical variable, or "DISABLED" if its type is not one of the type of
1111: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1112: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1113: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1114: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1115: disabled. Arguments of EXTERNAL are case sensitive because the external
1116: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1117: of known external functions but add the new list to the last. { "all" }
1118: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1119: external names of the known functions;
1120: - mkrplso.in is modified.
1121: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1134: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1135: VISIT does not find a name in level 1;
1136: - configure.in script is modified to add a new test (--enable-debug
1137: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1138: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1139: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1140: 'MATRIX' { 2 2 3 } GETR;
1141: - LOGSCALE intrinsic is improved and now, it can be used as
1142: { "main" "auxiliary" X Y } LOGSCALE;
1143: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1144: same than AXES:
1145: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1146: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1147: { { -10 10 } "automatic" } SCALE.
1148: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1149: because it changes only the dimension of the screen. To have a logarithmic
1150: scale, you must use LOGSCALE intrinsic:
1151: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1152: screen on second scale;
1153: - { X X } autoscale and { Y Y } logscale are now invalid;
1154: - *D is added (depth multiplication, for 3D graphics);
1155: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1156: and Z axes). The result of *S is the same than DUP DUP *H *W *D;

1173: in 0);
1174: - LAST is disabled in the main loop of DRAW intrinsic;
1175: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1176: evaluation of an equation, the system stack is returned corrupted to the
1177: sequencer;
1178: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1179: of a loop are not integer or real.
