delphi - How to deal with network drops and Indy IdTCPServer -

-

I have created a client / server application with the IDTCPP component. Customers should maintain and maintain consistent connections through the life of the application. If the network connection is dropped (which happens quite often because the clients connect to the wireless aircurdle) the client will automatically reconnect, all this works well.

My problem is working with sockets on the server related to the lost connection. They do not detect network drop and disconnect themselves. After reading several related articles, I learned that the server should know whether the connection was deleted. Some events will have to wait to find it.

So my question is, should I "handle" sockets from time to time to create some mechanism in my server? And if so, how? I thought that in a way all connections will be cycled through and they will try to send the data. I think it will trigger a required "event".

Any kind of heartbeats or ping signals, the server routinely server-side session Can be used to keep alive if the signal stops, and an expiration gap passes, the server may assume that the client has lost the connection.

(If the server only uses socket connection to send data to the client, then the server does not know that the customer receives it. Data may be somewhere interrupted.)

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
