Missing Dockerfile does not cause error

[kalantar]

I pushed a project that did not have a Dockerfile. The docker log (cf. /var/log/upstart/docker.log) below (actual names replaced by variables) shows the error. However, it appears that boatyard ignored the error and proceeded to try and push the image.

2014/11/11 07:27:47 POST /v1.10/build?nocache=true&t=REGISTRY:5000/USER/TAG
[af6a3213] +job build()
Can't build a directory with no Dockerfile
[af6a3213] -job build() = ERR (1)
[error] server.go:1048 Error making handler: Can't build a directory with no Dockerfile
[error] server.go:90 HTTP Error: statusCode=500 Can't build a directory with no Dockerfile
2014/11/11 07:27:48 POST /v1.10/images/REGISTRY:5000/USER/TAG/push
[af6a3213] +job push(REGISTRY:5000/USER/TAG)

A sequence of calls to the boatyard status API (only the value of the "Status" property is shown) does not indicate any problem:

curl http://BOATYARD_SERVER:80/api/v1/2ee0952b-9dc8-448b-592a-32f8cc5318b7/status
Tue Nov 11 13:26:20 UTC 2014>>
Tue Nov 11 13:26:51 UTC 2014>> Finished

The logs don't seem very helpful either.
