Warning messages: missing attribute sha256

[rrottmann]

Issue

When compiling the current code according to the README.md Compiling section, the interlock application brings lots of missing attribute warnings:

2018/09/16 11:15:59 status.go:59: missing attribute sha256
2018/09/16 11:15:59 api.go:192: {"response":["missing attribute sha256"],"status":"KO"}

System information

Go version:

go version go1.7.4 linux/arm

Linux system: Fresh install of Raspbian Stretch Lite (2018-06-27-raspbian-stretch-lite.img)

Linux raspberrypi 4.14.69+ #1141 Mon Sep 10 15:13:50 BST 2018 armv6l GNU/Linux

Workaround (possible unsafe)

The following patch will get rid of the attribute warnings but I think the introduced checksums are supposed to be there and the fix is to be found somewhere else.

I cannot reproduce this, I wonder if you have somewhat older javascript cached in your browser?

With the current code the api/file/list command issued by the UI always sets sha256 accordingly, example:

2018/09/17 10:26:36 api.go:49: 127.0.0.1:55978 POST /api/file/list 2018/09/17 10:26:36 json.go:33: {"path":"/signal","sha256":false}

Please try again by flushing your browser cache first.

Thanks for pointing that out! It was in fact the cached file_manager.js from an older release that lacked the sha256 code. It's working perfectly fine now. I reflashed the SD card and reinstalled interlock but the url did not change and the browser tried to use the file from cache.
