No Size2 sent in block-wise responses #300

Open tautologyclub opened 1 year ago

tautologyclub commented 1 year ago

RFC 7959 states that the size2 option in a request should cause server to provide the full file size. This does not seem to happen when I try it. Not 100% positive aiocoap is to blame, but the client uses a library that supposedly works well with other coap file servers.

Is this expected?

It does not yet (similar to how it didn't send block1 until recently).

I don't really plan to provide size2 conditional on the size2 in the request -- I consider that a slightly weird feature, and would rather send size2 unconditionally in the first block unless there are specific reasons not to do that.

Title updated as this is not exclusive to aiocoap-fileserver (and should happen on all block-wise situations when the library knows what's going on).
