You can tell it to consider them as functions by calling bind() >on them: Rather than wrapping another bind around them, is it possible to do some kind of clever casting, so that bind wouldn't see them as booleans? Btw, is the way I'm using function and bind not an intended use case? It seems natural enough, but by its behavior perhaps no one thought about it before... Thanks, aaron

[Thread] How to wait for a thread until it's blocked
by Christian Henning 10 Aug '05

10 Aug '05

Hi there, seems the attention span for my last question is over. ;-) I also think that my subject was misleading. My question isn't about terminating, completing, or canceling a thread. It's about putting a thread in a blocked state. Please consider the following code. All functions, except for the run(), are called by the GUI thread. The _oThread object is RAII-object ( Resource Allocation is Initialization ). // Only called by GUI thread fvAsynchronousSequencer::fvAsynchronousSequencer() : _oThread ( ) , _bTerminateSequencerThread ( false ) , _bStop( false ) { _oThread.create( this, _run ); } // Only called by GUI thread fvAsynchronousSequencer::~fvAsynchronousSequencer() throw() { _bTerminateSequencerThread = true; // wake up the thread, if necessary _oRunCondition.notify_one(); // wait until the thread is terminated { boost::mutex::scoped_lock oLock( _oTerminateMutex ); _oTerminateCond.wait( oLock ); } } // Only called by GUI thread void fvAsynchronousSequencer::start() { _bStop = false; _oRunCondition.notify_one(); } // Only called by GUI thread void fvAsynchronousSequencer::stop() throw() { _bStop = true; // I would like to wait until the _oThread is a in blocked position. } void fvAsynchronousSequencer::_run() throw() { boost::mutex::scoped_lock oLock( _oRunMutex ); // Wait until someone calls start() _oRunCondition.wait( oLock ); do { // do something useful while( _bStop ) _oRunCondition.wait( oLock ); } while( !_bTerminateSequencerThread ); // now finish destructing the sequencer _oTerminateCond.notify_one(); } So, I will ask again my question. Is there a way that the stop() will only return when the worker thread in in blocked state? Right now, I just set _bStop to true and stop() returns. This approach is of course rife for deadlocks. Thanks again, Christian

logical_and, boost::bind, and boost::function
by Simmons, Aaron 10 Aug '05

10 Aug '05

I'm trying to use boost::bind and boost::function with std::logical_not and I've run into some strange template magic that I don't understand. In the example below, I use boost::function to help compose several boost::bind calls so that I don't have to do it all on one line (I find that this improves readability). The problem is that when I do this, the functions that are bound with boost::bind never get called. They will get called only if I construct everything on one line. (???) Is this expected behavior? If so, why does it work like this? Thanks, aaron #include <algorithm> #include <functional> #include "boost/bind.hpp" #include "boost/function.hpp" using namespace std; using namespace boost; class test { public: void bindtest() { // test1: composed gradually for clarity // function<bool ()> funcFoo = bind(&test::foo, this); function<bool ()> funcBar = bind(&test::bar, this); function<bool ()> funcTest1= bind(logical_and<bool>(), funcFoo, funcBar); // doesn't call test::foo or test::bar! (returns true) bool test1= funcTest1(); cout << "test1= " << test1 << endl; // test2: composed directly on one line function<bool ()> funcTest2= bind(logical_and<bool>(), bind(&test::foo, this), bind(&test::bar, this) ); // calls test::foo and test::bar (returns false) bool test2= funcTest2(); cout << "test2= " << test2 << endl; } bool foo() { cout << "foo" << endl; return false; } bool bar() { cout << "bar" << endl; return false; } };

Re: [Boost-users] [Serialization] 1.33 RC1 nvp.hpp gotcha
by Richard Jennings 10 Aug '05

10 Aug '05

I am a bit baffled why you can get the example to compile! I can't try it on VC7.1 today, though I will tomorrow, however I can't see anything compiler specific about it: Serialization/nvp.hpp includes serialization/traits.hpp that defines BOOST_SERIALIZATION_TRAITS_HPP. Serialization/vector.hpp includes collections_save_imp.hpp that includes archive/basic_archive.hpp that checks for BOOST_SERIALIZATION_TRAITS_HPP being defined and thereby says #error. Therefore it appears that whenever vector.hpp is included after nvp.hpp that basic_archive will choke. BTW When I said that perhaps it only worked by luck before I meant that my application worked by luck as I was not overly careful about header inclusion order or what went in the precompiled headers and what didn't. I did _not_ mean that it's lucky the serialization library works! I have found it very simple to use and very powerful.

It is my intention that this issue be addressed with the simple rule: "all headers from the serialization directory should follow and headers from the archive directory" I believe that this rule should be very easy to follow. As a beneficial side-effect of flagging any usage of "archive" headers in include modules for classes. This would accidently link a serialization definition with implementation of a specific archive. > > In particular if you include serialization/nvp.hpp before > serialization/vector.hpp and you use that class in another module that > does not use archiving at all then that module will hit the error > directive, example below. This would surprise me. Your example looks good to me. So I built on my own machine. Both main.cpp and B.cpp compiled without problems with VC 7.1 . So we're out of sync somehow. > A solution would seem to be that serialization/nvp.hpp should only be > included in the module that includes archive headers. This wouldn't work and shouldn't be necessary. Lets beat upon your example some more until we get the same results. > I guess what I would like is some guidance on using serialization as > it's become a bit more tricky in my experience. I would hope that its not too tricky. The system is designed to be as tricky as necessary - but no trickier. > At least you can't willy-nilly include serialization headers in any order > in any headers > and expect the application to compile. True >Perhaps it only worked by luck before! LOL - well I do consider myself a lucky person !!!

To update, my problem with shared_ptrs not being released properly went away when I upgraded my Intel compiler from 8.1.019 to 8.1.025 on my machine at work. I hate to think how many days I have been working on this...:-) Cheers, tim

bug remains in posix_time io in 1.33RC2

[Thread] How to wait for a thread until it stopped
by Christian Henning 10 Aug '05

10 Aug '05

Hi there, I'm still working on the transistion from an old thread lib to the boost thread lib. I have two threads, the GUI thread and a worker thread. The worker thread is always inside a loop that only breaks if someone set the flag. The GUI thread has from time to time to stop the worker thread. This is currently done by setting a flag ( _bStop ) and the worker thread will eventually stop like: void run() { boost::mutex::scoped_lock oLock( _oRunMutex ); do { ... if( _bStop ) _oRunCondition.wait( oLock ); } while( _bTerminate == false ); } I believe that this implemention can lead to deadlocks. But how can I implement the behavior that the GUI thread will break until the worker thread has stopped. Thanks, Christian
