We're looking into the OCaml cohttp library. We want to build a simple REST-server based on top of it. We'd be using it to transfer large quantities of data. The cohttp library in this case will need to fall back to chunked transfer.
We dug a bit around in the source code and we suspect that chunked transfer is broken. It seems unable to distinguish between a POST that failed while doing chunked transfer encoding because the client terminated the connection
prematurely and a POST that successfully finished? When checking out the
code in Transfer_io.Chunked it seems that both cases end with a 'Done' value.
There
also seems to be a Final_chunk value but that's only used in the Transfer_io.Fixed module. I would
have expected this Final_chunk constructor to be used when the last line of a chunked transfer encoding is
encountered (reading a line containing '0' basically), but that doesn't seem to be the case.
Any suggestions?
