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

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

82: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
83: - Makefile.am are modified to authorize parallel builds;
84: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
85: and writes warning to standard output;
86: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)

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

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

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

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

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

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

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

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

1111: statistical variable, or "DISABLED" if its type is not one of the type of
1112: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1113: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1114: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1115: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1116: disabled. Arguments of EXTERNAL are case sensitive because the external
1117: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1118: of known external functions but add the new list to the last. { "all" }
1119: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1120: external names of the known functions;
1121: - mkrplso.in is modified.
1122: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

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

1174: in 0);
1175: - LAST is disabled in the main loop of DRAW intrinsic;
1176: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1177: evaluation of an equation, the system stack is returned corrupted to the
1178: sequencer;
1179: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1180: of a loop are not integer or real.

1213: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1214: is a quick and dirty workaround...);
