In what regards are "partial reads" less well covered by io.ReadAll than via json.Decoder? and the Decoder seemed to do the initial checking for me. Would the ReadAll() be able to recover from EOF state? io.ReadAll cannot "recover" from EOF just like an Decoder cannot. This EOF is smth that happens during _reading_ and both, io.ReadAll and json.Decoder do the actual read via identical methods. If your io.Reader allows reading up to EOF and than reading more (no idea how this is going to happen, but let's assume your underlying Reader somehow allows this) then it doesn't matter. io.ReadAll reads until EOF, forget about "partial reads". Decoding can be done on the read stuff. I think this is clearer. Once your io.Reader signals EOF you have to find some way to read more (???) or reset the Reader and this has nothing to do with _how_ you read from that Reader. V.

I'm trying to read json objects from a named pipe. The pipe will be filled intermittently by bash scripts. After the Decode() of the first object, any more calls to Decode() will return EOF. This seems proper since the script has completed, but once it errors with EOF, there doesn't seem to be a way to read any more. Is there a way to 'reset' the decoder so when another script writes to the pipe it can process the next object, or should I be doing some pipe length validation before trying to decode? Current read code snippet is... decoder := json.NewDecoder(fpipe) for { err := decoder.Decode(&msg) if err != nil { if err == io.EOF { // how to reset this? } else { logger.Fatal(err) } } else { // send out the msg -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
