Enabling disable_remote_exec removes output of Consul leader in self-hosted UI

[rbink]

We are using Consul v0.6.3 - with a cluster consisting of one leader and two followers - and self-hosted UI. We recently enabled disable_remote_exec and created a health check to validate the correct state of this property. The output of the health check - as reported in the UI - is as expected, however the output of the health check script of the Consul leader is not displayed in Consul UI. The output of the health check script of the Consul followers is displayed correctly in Consul UI. Both the Consul leader and followers are using the same script, installed in the same location with exactly the same rights. We were able to reproduce this problem and we did analyze the Consul codebase in order to find the cause of this problem, however without success.

leader: no output

a follower: output

Hi @rbink last night (!) we discovered an issue where there could be a side effect that cleared the output inadvertently. Is it possible for you to try out this change and see if it fixes the issue you are seeing?

#1934

Hi slackpad. Thanks for your very fast response. Good to read that you most likely found the same issue and fixed it. We raised a ticket to test your fix and get back to you when completed (which might take some time).

Hi slackpad, we recently updated Consul 0.6.3 to 0.6.4 and noticed that 0.6.4 did not contain the fix (as you mentioned as well). We will verify the fix once it has been released.

This was fixed in #1934.
