http_async_8bit_tcp_resolve with custom asio::io_service crashes #122

Closed brunonery closed 12 years ago

brunonery commented 12 years ago

The following program:


#include <boost/asio.hpp>
#include <boost/bind.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <boost/network/protocol/http/client.hpp>

using namespace boost::network;
using namespace boost::network::http;

typedef basic_client<http::tags::http_async_8bit_tcp_resolve, 1, 1> kaclient;

void timer(const boost::system::error_code& /* e */,
           boost::asio::deadline_timer* t)
{
    kaclient::request request_("http://www.google.com/");
    kaclient client_(t->get_io_service());
    kaclient::response response_ = client_.get(request_);

    t->expires_at(t->expires_at() + boost::posix_time::seconds(1));
    t->async_wait(boost::bind(timer, boost::asio::placeholders::error, t));
}

int main()
{
    boost::asio::io_service ioService;

    boost::asio::deadline_timer t(ioService, boost::posix_time::seconds(1));
    t.async_wait(boost::bind(timer, boost::asio::placeholders::error, &t));

    ioService.run();

    return 0;
}

gives the following error when run:

a.out: /usr/include/boost/smart_ptr/shared_ptr.hpp:418: T* boost::shared_ptr<T>::operator->() const [with T = boost::asio::io_service::strand]: Assertion `px != 0' failed.

This is a bug in the client code -- the client object can already be destroyed by the time the callback is invoked because the client instance is in the body of the timer callback.

neobobkrause commented 12 years ago

Not a problem with client code.

I'm experiencing the same problem, though I'm compiling with gcc 4.2 on macosx. I've been able to fix the problem by hacking the 0.9.4 code. Specifically, there are two async_client constructors in async_impl.hpp. The problem appears to be that the constructor that accepts an io_service doesn't initialize the resolverstrand data member. Adding the following line to the body of that constructor fixed the problem for me...

      connection_base::resolver_strand_.reset(new
                boost::asio::io_service::strand(service_));

Hope this helps,

Oh, okay. Can you submit a pull request to fix this? It might make sense to have a 0.9.5 to address these issues. I can start a branch if you're up for this.

Not a problem with client code.

I'm experiencing the same problem, though I'm compiling with gcc 4.2 on macosx. I've been able to fix the problem by hacking the 0.9.4 code. Specifically, there are two async_client constructors in async_impl.hpp. The problem appears to be that the constructor that accepts an io_service doesn't initialize the resolverstrand data member. Adding the following line to the body of that constructor fixed the problem for me...

  connection_base::resolver_strand_.reset(new
            boost::asio::io_service::strand(service_));

Hope this helps,

The branch is 0.9-devel on cpp-netlib/cpp-netlib. If you can send a pull request against that branch we can start the process of getting it released as 0.9.5.
