c++ - boost asio read buffer -


My question is, when you do not know the message size, then what is the best way to read boost TCP socket ? It's a sample I've just put in the size of 10. The code is in different headers, but I did not feel the need to include it all

/////////// HPP 

  Typedef boost :: asio :: ip :: tcp :: resolver tresolver; Typedef boost :: asio :: ip :: tcp :: resolver :: query TResolverQuery; Typedef boost :: asio :: ip :: tcp :: endpoint tendpoint; Typedef boost :: asio :: ip :: tcp :: socket Tsocket; Typedef boost :: asio :: ip :: tcp :: acceptor Tacceptor; #Fine for 10th

//////////// cpp 

  while (true) {cout & lt; & Lt; "Recieve" & lt; & Lt; Endl; Promote: shared_ptr & lt; Tapetector & gt; Acceptor (new boost :: asio :: ip :: tcp :: acceptor (* m_io_service)); Boost :: system :: error_code ec; TResolverQuery query (it-> getHost (), boost :: lexical_cast & lt; std :: string & gt; (this- & gt; getPort ()); TResolver resolver (* m_io_service); Formatting endpoint = * resolver Risol (query); Acceptable- & gt; Open (Endpoint. Protocol ()); Acceptor- & gt; Set_option (boost :: asio :: ip :: tcp :: acceptor :: reuse_address (true)); Acceptable- & gt; Dam (end point); Acceptor-> (Listen); Promote: shared_ptr & lt; Tsocket & gt; Soknow (New Tsocket (* m_io_service)); Acceptant- & gt; Accept (* Soknow, End Point); Promotion :: Array & lt; Char, tsize & gt; Buf; Boost :: asio :: read (* socknew, boost :: asio :: buffer (buf), ec); Cout.write (buf.data (), Tsize); Cout & lt; & Lt; Std :: endl; Socknew-> Closed (boost :: asio :: ip :: tcp :: socket :: shutdown_both, ec); Cout & lt; & Lt; "Thread ID" & lt; & Lt; Promote: this_thread :: get_id () & lt; & Lt; Endl; }

The two most common ways to use the protocol is that message, or at the end Message is the marker.

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
