-remove ManagedEncryptedFileDownloader._reupload
-clean up reflector functions in Daemon, move to reflector.reupload
-check ConnectionLost in reflector client
-close sd blob file handle when it wont be sent (otherwise read handle stays open)
-log reflector sd info
-give reflector client factory a lbry file
-move status message on connectionDone to client, indicate if blobs
were sent or not (and how many blobs reflector still needs, if any)
-only try uploading failed blob once after first failure, to prevent
indefinite retries
-add {‘sd_blob_hash’: …, ‘sd_blob_size ‘: …} query type with
{‘send_sd_blob’: True/False, ‘needed_blobs’: []} response
this allows the reflector client to know how much of a stream reflector
already has covered, as to minimize the number of subsequent requests
and prevent streams from being partially reflected
-remove empty {} request
previously only the sd blob was reflected, if the server indicated it
needed the blob then the rest of the stream would follow. this allowed
for many streams to be partially reflected, where for whatever reason
the connection was broken before the full upload was completed. this
meant that on a subsequent run, the client would falsely believe
reflector had the whole stream when it actually only had some portion
of it.
this solution isn’t ideal, I’m most of the way done with a better one,
but this can be deployed now.
