Patching of file isn't working about cdc-file-transfer

[ljusten]

Odd, I've never seen that. If the server chunks have not been fully transmitted, it is possible that the chunk.hash is not found until the server catches up sending the data. In that case, the patcher will just try again later until server_chunk_receiver.AllChunksReceived() is true. Is the chunk.hash not found even after server_chunk_receiver.AllChunksReceived() becomes true?

Is this reproducible with a very small file (<1KB)? In that case, there should only be one chunk, and it should be easy to check what's going on. It could be 3 things: The chunkers/hashers on the client and server get different input data (should not be the case as the files are the same), they produce different outcomes (should not be the case as both chunker and hasher should be deterministic) or something else is wrong and the hash doesn't get transmitted properly.

Also, what version are you on? 1.0.0 or latest? If you're on latest, does it repro in 1.0.0?

Hi Lutz,

Thanks very much for responding. In adding some additional logging it looks like somehow the build of the server was out of sync with the build on the client. Not clear how that happened, but at least that's the answer.

Best,
Alex

Yeah I was about to suggest that. We made a tiny change to fastcdc.h, which would perfectly explain those symptoms.
