> What OS are you using? Is the session's work CPU bound?
I'm on Windows XP, sry but I can't understand what you mean with the
second question...
Just take your sample in "server.cpp": I need to be able to change the
code (in the session or server object, dunno where...) so that the server
is always free to accept (and process) a new connections even if there are
one or more active sessions taking a very long time to generate and send
theirs response.
For example:
void Session::handle_read(const asio::error_code& err, size_t length)
{
--op_count_;
if (!err)
{
read_data_length_ = length;
++unsent_count_;
if (unsent_count_ == 1)
{
very_very_long_operation(); // Process the client request
op_count_ += 2;
std::swap(read_data_, write_data_);
async_write(socket_, buffer(write_data_, read_data_length_),
strand_.wrap(
boost::bind(&session::handle_write, this,
placeholders::error)));
socket_.async_read_some(buffer(read_data_, block_size_),
strand_.wrap(
boost::bind(&session::handle_read, this,
placeholders::error,
placeholders::bytes_transferred)));
}
}
if (op_count_ == 0)
io_service_.post(boost::bind(&session::destroy, this));
}
Session::very_very_long_operation() takes a lot of time :) I need in the
meanwhile to be able in the server to accept new connections, how can I do
that? I tried calling ios.run() from multiple threads as the documentation
said but the server is always locked until the session's operation is
completed...
P.S.: be patient plz my english is not very good :)
