https://svn.boost.org/trac10/ticket/7682 <p> 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. </p> <p> 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. </p> <p> 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'. </p> <pre class="wiki">#include &lt;boost/interprocess/managed_shared_memory.hpp&gt; #include &lt;boost/interprocess/sync/named_mutex.hpp&gt; #include &lt;boost/interprocess/sync/named_condition.hpp&gt; #include &lt;boost/interprocess/sync/scoped_lock.hpp&gt; #include &lt;iostream&gt; int main() { boost::interprocess::managed_shared_memory managed_shm(boost::interprocess::open_or_create, "shm", 1024); int *i = managed_shm.find_or_construct&lt;int&gt;("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&lt;boost::interprocess::named_mutex&gt; lock(named_mtx); while (*i &lt; 10) { if (*i % 2 == 0) { ++(*i); named_cnd.notify_all(); named_cnd.wait(lock); } else { std::cout &lt;&lt; *i &lt;&lt; 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"); } </pre> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/7682 Trac 1.4.3 jeff.trull@… Thu, 24 Jan 2013 02:45:36 GMT https://svn.boost.org/trac10/ticket/7682#comment:4 https://svn.boost.org/trac10/ticket/7682#comment:4 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> <p> (In <a class="changeset" href="https://svn.boost.org/trac10/changeset/82796" title="Fixes #7682">[82796]</a>) Fixes <a class="reopened ticket" href="https://svn.boost.org/trac10/ticket/7682" title="#7682: Bugs: boost 1.52 named_mutex/named_condition pairing broken (reopened)">#7682</a> </p> Ticket Jeff Trull <edaskel@…> Sat, 09 Feb 2013 19:17:14 GMT https://svn.boost.org/trac10/ticket/7682#comment:7 https://svn.boost.org/trac10/ticket/7682#comment:7 <ul> <li><strong>status</strong> <span class="trac-field-old">closed</span> → <span class="trac-field-new">reopened</span> </li> <li><strong>resolution</strong> <span class="trac-field-deleted">fixed</span> </li> </ul> <p> reopening the issue </p> Ticket Ion Gaztañaga Wed, 23 Dec 2015 23:35:03 GMT
