#5722 closed Bugs (fixed)

Compilation error when boost/signals.hpp is included before asio.hpp

Reported by: anonymous Owned by: chris_kohlhoff
Milestone: To Be Determined Component: asio
Version: Boost 1.47.0 Severity: Problem
Keywords: Cc:

Description

On the mailinglist it has been discovered, that including boost/signals.hpp before boost/asio.hpp causes a compile error in asio/detail/impl/signal_set_service.ipp:74 saying "boost::signal": use of class template requires template argument list.

The following testcase has been used to confirm this under MSVC10:

#include <boost/signals.hpp>
#include <boost/asio.hpp>

int main(int argc, char **argv)
{
    return 0;
} 

Igor R provided the following patch for boost\asio\detail\impl\signal_set_service.ipp:71:

- signal(signal_number, asio_signal_handler);
+ ::signal(signal_number, asio_signal_handler);

(In [74815]) Explicitly specify the signal() function from the global namespace. Refs #5722

  • Resolution set to fixed
  • Status changed from new to closed

(In [74863]) Merge from trunk...

Fix compile error in regex overload of async_read_until.hpp. Fixes #5688

Explicitly specify the signal() function from the global namespace. Fixes #5722

Don't read the clock unless the heap is non-empty.

Change the SSL buffers sizes so that they're large enough to hold a complete TLS record. Fixes #5854

Make sure the synchronous null_buffers operations obey the user's non_blocking setting. Fixes #5756

Set size of select fd_set at runtime when using Windows.

Disable warning due to const qualifier being applied to function type.

Fix crash due to gcc_x86_fenced_block that shows up when using the Intel C++ compiler. Fixes #5763

Specialise operations for buffer sequences that are arrays of exactly two buffers.

Initialise all OpenSSL algorithms.

Fix error mapping when session is gracefully shut down.

Various performance improvements:

  • Split the task_io_service's run and poll code.
  • Use thread-local operation queues in single-threaded use cases (i.e. concurrency_hint is 1) to eliminate a lock/unlock pair.
  • Only fence block exit when a handler is being run directly out of the io_service.
  • Prefer x86 mfence-based fenced block when available.
  • Use a plain ol' long for the atomic_count when all thread support is disabled.
  • Allow some epoll_reactor speculative operations to be performed without holding the lock.
  • Improve locality of reference by performing an epoll_reactor's I/O operation immediately before the corresponding handler is called. This also improves scalability across CPUs when multiple threads are running the io_service.
  • Pass same error_code variable through to each operation's complete() function.
  • Optimise creation of and access to the io_service implementation.

Remove unused state in HTTP server examples.

Add latency test programs.
