2012-05-21 Alexandre Duret-Lutz <adl@lrde.epita.fr>

* configure.ac: Bump the version number to 1.2.1a.
* NEWS: Summarize all changes since 1.2.1.
* README: Warn this is not 1.2.1, and add pointers to NEWS and
ChangeLog.
2012-05-21 Tomáš Babiak <xbabiak@fi.muni.cz>
Count deterministic automata and deterministic states.
* src/BuchiAutomaton.h, src/BuchiAutomaton.cc
(BuchiState::isDeterministic, BuchiAutomaton::isDeterministic,
BuchiAutomaton::nondeterminismIndex): New methods.
* src/TestOperations.cc (generateBuchiAutomaton): Collect
nondeterminism indices, and count deterministic automata.
* src/TestStatistics.cc, src/TestStatistics.h: Add storage
for these statistics.
* src/StatDisplay.cc (printBuchiAutomatonStats,
printCollectiveStats): Display these statistics.
2012-04-27 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* doc/gpl.texi: Fix make pdf for newer texinfo.tex.
2012-04-27 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* configure.ac: Do not check for mkstemp(), it is not used.
2010-04-07 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Accept W and M in lbtt-translate --spot.
* src/SpotWrapper.cc: Translate W and M operators.
2010-01-22 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Let "make dvi" work on Ubuntu.
* doc/lbtt.texi (The formula generation algorithm): Use op^\prime
instead of op', because etex on Ubuntu hangs (an infinite loop?)
on the later when texi2dvi tries to compile a dvi.
2010-01-21 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Kill some warnings on Ubuntu.
* src/UserCommandReader.cc (UserCommandInterface): Explicitly
ignore the return code of system() to kill a warning.
* src/TestOperations.cc (generateBuchiAutomaton): Explicitly
ignore the return code of write() to kill a warning.
2010-01-16 Guillaume Sadegh <sadegh@lrde.epita.fr>
Add a missing include.
* src/translate.cc: exit(2) requires cstdlib.
2009-11-26 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix generation of random formulae on 64bits systems.
* src/main.cc (testLoop): Generate random short ints between 0 and
SHRT_MAX, not between 0 and LONG_MAX. On systems where long ints
are 64bits, LRAND(0,LONG_MAX) was returning a value with the lower
32 bits set to 0, and the latter truncation to short int always
yielded the value 0. Consequently all generated formulae were
identical...
2009-11-25 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/Configuration.cc (registerAlgorithm): Do not complain about
a missing path for disabled algorithms.
2009-06-12 Guillaume Sadegh <sadegh@lrde.epita.fr>
Adjust to support the Intel compiler (icpc).

* Makefile.am: Add the directory `m4' as an includedir of
autoconf's macros.

Adjust parser to Bison 2.4.1.

please newer versions of Bison. With Bison 2.4.1 the various
token used by yyerror() are now defined only after the first
%{...%} block has been emitted (in which yyerror() was previously
defined).
2008-03-13 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/main.cc: Include <climits> for LONG_MAX. lbtt won't
compile with g++-4.3 otherwise.
* src/Ltl-parse.yy (matchCharactersFromStream): Declare the chars
as const to kill a g++ warning.
* src/NeverClaim-parse.yy (yyerror): Declare the error
message as const to kill a g++ warning.

2004-03-04 Heikki Tauriainen <heikki.tauriainen@hut.fi>
* src/Config-lex.ll, src/Config-parse.yy, src/Configuration.h,
src/Configuration.cc: Rewrite the configuration file parser to
allow reusing a common set of functions for changing the various
settings independently of whether the settings were given in the
configuration file or as command-line options. Rearrange the
structure of Configuration::AlgorithmInformation, remove the
"nopause" and "pauseonbreak" command line options (and make
"pause" an alias of "interactive"), recognize lists of
interactivity modes (with the new mode "onbreak") both in the
configuration file and command line, and add the new
configuration setting "translatortimeout". In more detail,
the changes are:
* src/Config-lex.ll: Do not include any standard headers. Add
%option nounput to suppress a compiler warning. Accept
"Implementation" or "Translator" as an alias of the Algorithm
block identifier. Do not accept newlines in "option = value"
strings. Do not interpret option values in the lexer. Make
specifying option values more flexible: quotes are now needed
only for values including white space. Both single and double
quotes may be used (as before, \ works as an escape character in
double quotes). Reject values with unmatched quotes. Remove the
getCharacter function (add rules for matching unknown tokens in
full).
* src/Config-parse.yy: Do not include the cstdio header. Add
namespace StringUtil to the current namespace.
([declarations]) Change %union declaration to make all semantic
values constant C-style strings. Remove tokens CFG_TRUTH_VALUE,
CFG_INTERACTIVITY_VALUE, CFG_FORMULA_MODE_VALUE,
CFG_STATESPACE_MODE_VALUE, CFG_PRODUCT_TYPE_VALUE, CFG_INTEGER,
CFG_REAL, CFG_INTEGER_INTERVAL and CFG_STRING_CONSTANT. Add
new token CFG_VALUE and nonterminal equals_value.
(algorithm_information): Replaced with `algorithm_name',
`algorithm_path', `algorithm_parameters' and `algorithm_enabled'.
(current_block_type, current_option_type): Removed.
(yyerror): Make parameter const. Remove the loop for reading the
remainder of the current token (the token is recognized in full
directly by the lexer). Remove error messages for all tokens in
the above list.
(checkIntegerRange, checkProbability, isLocked): Removed.
([grammar rule `equals_value']): New rule.
([grammar rules for the "Algorithm" configuration file section]):
Read the implementation information into `algorithm_name',
`algorithm_path', `algorithm_parameters' and `algorithm_enabled'.
Use the functions provided by the Configuration class to update
the configuration.
([grammar rules for the other configuration file sections]): Use
the functions provided by the Configuration class to update the
configuration. Remove the rules `formula_size' and
`statespace_size'.
* src/Configuration.h: Include the cstdio header. Add
declarations for variables and functions provided by the parser.
Declare yyparse() as a friend.

The options
--no{{comparison,consistency,intersection}{test,check},
abbreviatedoperators} return the same OPT_ constant as the
corresponding positive option.
The --interactive and --pause options take an optional argument.
Remove the --nopause and --pauseonerror command line options.
Store the command line parameters into a vector of <opttype,arg>
pairs (preprocess the special options --configfile, --formulafile,
--help, --logfile, --showconfig, --showoperatordistribution,
--skip and --version; preprocess also the options accepting an
optional argument). Then read the configuration file. Add the
internal model checking algorithm to the set of algorithms if
necessary here instead of in src/main.cc (testLoop). Finally
process the parameter vector again to override any settings made
in the configuration file.
Use the new functions for modifying the configuration.
Allow symbolic algorithm identifiers for the options --enable
and --disable.
Make error messages more consistent.
Exit with the status 2 if an unknown command line option was
encountered or an argument for an option was missing.

enabled; tell also the value of the timeout for translators.

`global_options.handle_breaks' and
`global_options.translator_timeout' to false and 0, respectively.
(Configuration::registerAlgorithm): New function for adding a

(Configuration::readProductType, Configuration::readFormulaMode)
(Configuration::readStateSpaceMode)
(Configuration::readTranslatorTimeout): New functions. The
