Synic

Client-Server application for transfering files over HTTP automatically.

The protocol is simple:

• When the server starts, it starts to resolve md5 hashes of the files
• The client starts oauth2 machine-to-machine authentication
• Once got the access token, use it for all of the following calls
• The client asks if there's something to do
• The server responds no, if there's nothing to do
• The server responds yes if there's a file to transfer, and gives the path for the file, with a status
• The client calls the url given by the server, and checks its status (if it's available to download)
• If it is available to download, downloads it
• Once finished, the client checks the checksum of the file
• If the checksum is correct, sends an ACK to the server, which discards the file
