boost 1.52 named_mutex/named_condition pairing broken

[damian.coventry@…]

The following program works in boost 1.47, however in 1.52 it does not. To test it, run 2 instances. The 2nd instance should output the numbers 1, 3, 5, 7, 9.

Under 1.52, the program outputs the number 1, and then does nothing. The fault appears to be with the named_condition and named_mutex classes.

Tested under Windows 7 Pro, SP1, using Visual Studio 2010 v10.0.40219.1 SP1Rel. The test was done with a statically linked boost date time, with Platform Toolset set to v90, i.e. linked with the library 'libboost_date_time-vc90-mt-sgd-1_47.lib'.

#include <boost/interprocess/managed_shared_memory.hpp> 
#include <boost/interprocess/sync/named_mutex.hpp> 
#include <boost/interprocess/sync/named_condition.hpp> 
#include <boost/interprocess/sync/scoped_lock.hpp> 
#include <iostream> 

int main() 
{ 
  boost::interprocess::managed_shared_memory managed_shm(boost::interprocess::open_or_create, "shm", 1024); 
  int *i = managed_shm.find_or_construct<int>("Integer")(0); 
  boost::interprocess::named_mutex named_mtx(boost::interprocess::open_or_create, "mtx"); 
  boost::interprocess::named_condition named_cnd(boost::interprocess::open_or_create, "cnd"); 
  boost::interprocess::scoped_lock<boost::interprocess::named_mutex> lock(named_mtx); 
  while (*i < 10) 
  { 
    if (*i % 2 == 0) 
    { 
      ++(*i); 
      named_cnd.notify_all(); 
      named_cnd.wait(lock); 
    } 
    else 
    { 
      std::cout << *i << std::endl; 
      ++(*i); 
      named_cnd.notify_all(); 
      named_cnd.wait(lock); 
    } 
  } 
  named_cnd.notify_all(); 
  boost::interprocess::shared_memory_object::remove("shm"); 
  boost::interprocess::named_mutex::remove("mtx"); 
  boost::interprocess::named_condition::remove("cnd"); 
}

I can confirm this behavior on 1.52 and also in trunk, for gcc 4.7.2.

Breaking rev is 80146 "[named_/interprocess]sharable_mutex & [named_/interprocess]condition_any implemented"

Thanks for the report. It was also reported in #8008.

(In [82796]) Fixes #7682

[Jeff Trull <edaskel@…>]

I can confirm this works in trunk now

It doesn't work on 1.55.0. I have verified it on Boost 1.55.0.

Can you please elaborate what is not working? Current version seems to works perfectly. Boost 1.55 is two years old, can you please check that currect version (1.60.0) works as expected for you?
