Hi,

I am looking to understand the protocol between renderd and mod_tile. I can capture the data thats going across the network, thats easy, and I have found this https://github.com/openstreetmap/mod_tile/blob/master/protocol.h but of course that does not tell me how the c variables translate into bits on the network and I am unable to find much more with Google.

Any documentation on what mod_tile sends down the socket to renderd and what renderd sends back would be very helpful.

Thanks

Scott

The struct you're seeing in protocol.h is what gets sent over the network, verbatim. See https://github.com/openstreetmap/mod_tile/blob/master/mod_tile.c#L216 which does the sending. The same struct is used as a return message, see https://github.com/openstreetmap/mod_tile/blob/master/mod_tile.c#L246 which receives the message.
