Question about the images in pouch about pouch

[HusterWan]

@allencloud @skoo87 i create a pr to fix this problem, please review #160 , if there is any problem, you can ping me any time. 3x

[HusterWan]

also countered this problem， @gaocegege you should pull docker images like:
pouch pull docker.io/library/hello-world:latest
pouch set default registry address: docker.io， but likely not worked

[HusterWan]

there also has a bug: client decode failed, because server return 200 ( should 500)
resp.WriteHeader(http.StatusInternalServerError) // this code does not worked
may i can fix this problem for you @allencloud

[allencloud]

We will improve this part asap. This is a known insufficient.

[allencloud]

It couldn't be better. Just submit PR and enjoy hacking. @HusterWan 👍

[gaocegege]

@HusterWan Thanks for your information

failed to decode: invalid character 'i' in literal false (expecting 'l') <===== The reason may be that the server side(pouchd) closed the connection, not http status code. The CLI read data from the tcp connection and decode them with json format, but not handle the error when connection closed. @HusterWan Welcome to post a PR to fix it, thanks.

@skoo87 i am working on it, the problem maybe more complicated, golang ResponseWriter allow call WriteHeader only once, so if the server(pouchd)'s goroutine call ResponseWriter.Writer once when pull image, the http code will be set 200, and later call resp.WriteHeader(http.StatusInternalServerError) will not work .
https://golang.org/pkg/net/http/#ResponseWriter

so i am thinking maybe we can not only use http code to judge if pull image is ok
