But relying on this is a very bad habit. Probably the worst thing about using blocking sockets is what happens when the other side comes down hard without doing a close. Your socket is likely to hang.
TCP is a reliable protocol, and it will wait a long, long time before giving up on a connection. Do not try to kill the thread - part of the reason that threads are more efficient than processes is that they avoid the overhead associated with the automatic recycling of resources.
In other words, if you do manage to kill the thread, your whole process is likely to be screwed up. In Python, you use socket. You do this after creating the socket, but before using it.
The major mechanical difference is that send , recv , connect and accept can return without having done anything. You have of course a number of choices. You can check return code and error codes and generally drive yourself crazy.
Your app will grow large, buggy and suck CPU. In C, coding select is fairly complex. You pass select three lists: the first contains all sockets that you might want to try reading; the second all the sockets you might want to try writing to, and the last normally left empty those that you want to check for errors. You should note that a socket can go into more than one list.
The select call is blocking, but you can give it a timeout. This is generally a sensible thing to do - give it a nice long timeout say a minute unless you have good reason to do otherwise. In return, you will get three lists. They contain the sockets that are actually readable, writable and in error. Each of these lists is a subset possibly empty of the corresponding list you passed in.
If a socket is in the output readable list, you can be as-close-to-certain-as-we-ever-get-in-this-business that a recv on that socket will return something. Same idea for the writable list. Maybe not all you want to, but something is better than nothing. Actually, any reasonably healthy socket will return as writable - it just means outbound network buffer space is available. If it comes out in the readable list, your accept will almost certainly work.
