Removes some hacks due to Swig 2's incomplete C++11 support and adds
checks for version 3 at configuration time as well as in swig.h
|
|
C++11 supports explicitly deleting functions that should not be used
(explictly or implictly), e.g. copy or assignment constructors. We were
previously using the CVC4_UNDEFINED macro that used a compiler-specific
attribute. The C++11 feature should be more portable.

* Fixes --hide-zero-stats (and really skips the 0 values)
* Removes the additional newline after each statistic
* Introduces theory::getStatsPrefix(TheoryId) to generate consistent
prefixes for statistics based on the theory id
(e.g., THEORY_BV -> "theory::bv").

Removing more miscellaneous throw specifiers.

Print statistics if CVC4 gets a SIGTERM signal.

* Remove front end hack for sygus.
* Remove other hack, add sygus solution output mode.
* Clang format
* Minor

This adds option --copyright which displays copyright information for CVC4. It further extends --show-config with copyright information and adds a banner with copyright information in interactive mode.

The variable `g` could be set multiple times depending on
the options (e.g. a combination of `--dump-unsat-cores`
and `--dump-synth`), which could lead to memory leaks and
missing output. This commit fixes the issue by replacing
`g` with a list of `getterCommands` that are all executed and
deleted.

Commit 546d795470ca7c30fc62fe9b6c7b8e5838e1eed4
caused our nightly builds to fail because it did
not replace CVC4_THREADLOCAL with
CVC4_THREAD_LOCAL in interactive_shell. This
commit fixes the issue and adds readline to
Travis, s.t. readline related code gets compiled
as part of our CI tests.

C++11 introduced the thread_local keyword, so we don't need to use
non-standard extensions or our custom pthread extension anymore.
The behavior was previously introduced as a workaround in commit
753a072c542c1c254d7c6adbf10e091ba585ede5. This commit
introduces the macro CVC4_THREAD_LOCAL that can be used to
declare variables as thread local. For Swig, this macro is defined to
be empty.

sygus), update regressions.

With C++11, we don't need PtrCloser anymore because we can
just use std::unique_ptr.

decision procedure to share selectors of the same type across multiple constructors. Major rewrite of the SyGuS solver. Adds several new strategies for I/O example problems (PBE) and invariant synthesis. Major simplifications to sygus parsing and synthesis conjecture representation. Do not support check-synth in portfolio. Add sygus regressions.

As pointed out by @cpitclaudel in pull request #172, we are using the same
handler for SIGSEGV and SIGILL and ill_handler() is unused. This commit changes
the SIGILL handler to ill_handler().

The Windows build was missing the `print_statistics()` function, this commit
moves the function out of the `#ifndef __WIN32__` guard.

This commit fixes two issues reported by Coverity:
- Fixes the check whether the buffer is full in safe_print_hex
- Removes dead code in safe_print for floating-point values
Additionally, it fixes an issue reported by Andy where the names of the
statistics were printed as "<unsupported>" due to calling the const char*
version instead of the std::string version of safe_print.
Finally, this fixes an issue where --segv-spin would not print the program name
because it was a const char*. The program name is now stored as a string.
NOTE: As a side effect, the last part also fixes Coverity issue 1362944, which
has been in CVC4 for a long time.

As reported in bug 769, the signal handlers currently use unsafe
functions such as dynamic memory allocations and fprintf. This commit
fixes the issue by introducing functions for printing statistics in
signal handlers (functions with the `safe` prefix). It also avoids
copying statistics, which further avoids dynamic memory allocation. The
safe printing of statistics has some limitations (it does not support
SExprStats or printing CVC4::Result), which should not matter much in
practice. Printing statistics in a non-signal handler is not affected by
these changes as that uses a separate code path (the functions without
the `safe` prefix).
Additional changes:
- Remove ListStat as it is not used anywhere
- Add unit test for safe printing statistics

As mentioned in bug 741, CVC4 was parsing `.smt2` files using the
SMT-LIB v2.0 standard by default. This commit switches to v2.5.

- Options
-- Added the new option attribute :notify. One can get a notify() call on the Listener after a the option's value is updated. This is the new preferred way to achieve dynamic dispatch for options.
-- Removed SmtOptionsHandler and pushed its functionality into OptionsHandler and Listeners.
-- Added functions to Options for registering listeners of the notify calls.
-- Changed a number of options to use the new listener infrastructure.
-- Fixed a number of warnings in options.
-- Added the ArgumentExtender class to better capture how arguments are inserted while parsing options and ease memory management. Previously this was the "preemptGetopt" procedure.
-- Moved options/options_handler_interface.{cpp,h} to options/options_handler.{cpp,h}.
- Theories
-- Reimplemented alternative theories to use a datastructure stored on TheoryEngine instead of on Options.
- Ostream Handling:
-- Added new functionality that generalized how ostreams are opened, options/open_stream.h.
-- Simplified the memory management for different ostreams, smt/managed_ostreams.h.
-- Had the SmtEnginePrivate manage the memory for the ostreams set by options.
-- Simplified how the setting of ostreams are updated, smt/update_ostream.h.
- Configuration and Tags:
-- Configuration can now be used during predicates and handlers for options.
-- Moved configuration.{cpp,h,i} and configuration_private.h from util/ into base/.
-- Moved {Debug,Trace}_tags.* from being generated in options/ into base/.
- cvc4_private.h
-- Upgraded #warning's in cvc4_private.h and cvc4_private_library.h to #error's.
-- Added public first-order (non-templatized) member functions for options get and set the value of options outside of libcvc4. Fixed all of the use locations.
-- Made lib/lib/clock_gettime.h a cvc4_private_library.h header.
- Antlr
-- Fixed antlr and cvc4 macro definition conflicts that caused warnings.
- SmtGlobals
-- Refactored replayStream and replayLog out of SmtGlobals.
-- Renamed SmtGlobals to LemmaChannels and moved the implementation into smt_util/lemma_channels.{h,cpp}.

- The functionality the get the StatisticsRegistry attached to the SmtEngine was previously through StatisticsRegistry::current(). This is the dominant StatisticsRegistry in the code. (There is another StatisticsRegistry attached to the NodeManager.) Having this be a static function on StatisticsRegistry requires the use of an SmtEngine in the wrong compilation unit.
- Usages of StatisticsRegistry::current() that were visible in prop/{bvminisat,minisat} has been removed. A pointer to the relevant StatisticsRegistry should be passed instead into the constructor.
- The function StatisticsRegistry::current() has been replaced by SmtScope::currentStatisticsRegistry(). SmtScope is in the libcvc4 package, where SmtEngine is available in the compilation unit.
- The function smtStatisticsRegistry() is a synonym for SmtScope::currentStatisticsRegistry() in smt/smt_statistics_registry.h. This header has fewer include dependencies than the one for SmtScope.
- Correspondingly, the static functions StatisticsRegistry::{registerStat, unregisterStat} have been removed. One should instead use smtStatisticsRegistry()->{registerStat,unregisterStat} instead.
- The KEEP_STATISTIC macro has been moved into smt/smt_statistics_registry.h.
- Documents the reason StatisticsRegistry is CVC4_PUBLIC. This lets me remove the warning I added.
- Removing most operators for timespec from statistics_registry.h file. These a bit error prone in clang.
- Most of the really confusing ifdef's in util/statistics_registry.h are gone.

- The options replayStream, lemmaInputChannel, lemmaOutputChannel have been removed due to their datatypes. These datatypes were previously pointers to types that were not usable from the options/ library.
- The option replayLog has been removed due to inconsistent memory management.
- SmtGlobals is a class that wraps a pointer to each of these removed options. These can each be set independently.
- There is a single SmtGlobals per SmtEngine with the lifetime of the SmtEngine.
- A pointer to this is freely given to the user of an SmtEngine to parameterize the solver after construction.
- Selected classes have been given a copy of this pointer in their constructors.
- Removed the dependence on Node from Result. Moving Result back into util/.
