Is this printed only for the json dumper, or for all of them?
Put differently, i don't think it should be in the console output, it is getting rather crowded already.

Removed from console and added only to JSON

Just use HOST_NAME_MAX

HOST_NAME_MAX was not present on OSx, added local initialization.
The Job on Travis failed in config, can you please have a look at it?

Again, why invent a magic number.
MAX_COMPUTERNAME_LENGTH+1 ?
And that being said, isn't that a rather too big to have as an array on stack?
Maybe use resized std::string?

What is "system name"?
How is this different from "host name"?
If it is exactly the "host name", just use that term?

Does this work? Is this already done elsewhere in the library?
wchar is bigger than char, what makes sure that this isn't lossy?

Using Standard wstring_convert to fix this

Can't you just use HOST_NAME_MAX directly, why do you need COUNT variable?

Removing unnecessary COUNT variable references, using macro directly

Are you 100.0% sure this is safe?
https://docs.microsoft.com/en-us/windows/desktop/api/winbase/nf-winbase-getcomputernamew

On input, specifies the size of the buffer, in TCHARs. On output, the number of TCHARs copied to the destination buffer, not including the terminating null character.

I'd recommend to use 'returned' DWCOUNT.

Initialising TCHAR to null and only copying DWCOUNT into string.

So there's good news and bad news.

👍 The good news is that everyone that needs to sign a CLA (the pull request submitter and all commit authors) have done so. Everything is all good there.

😕 The bad news is that it appears that one or more commits were authored or co-authored by someone other than the pull request submitter. We need to confirm that all authors are ok with their commits being contributed to this project. Please have them confirm that here in the pull request.

Note to project maintainer: This is a terminal state, meaning the cla/google commit status will not change from this state. It's up to you to confirm consent of all the commit author(s), set the cla label to yes (if enabled on your project), and then merge this pull request when appropriate.

CLAs look good, thanks!

We are sure that this won't contain \\? (see executable_name)

Do we want to print "Unable to Get Host Name"?2

I wonder if this should be after the executable_name.

No. We should check and only output if it's available.

Yes, I checked the output of the function, it just outputs the hostname for windows without the \\

Addressed

I am not sure about this one, it can be done, but since the output being in json only, is it desirable?

Aren't we still always printing it?

Looks about right other than this.

are you talking about the 2nd point?
I have placed an empty string incase it fails to fetch the host name

LebedevRI

In general seems to look ok, but i'd prefer to leave this for @dominichamon.

return empty string and don't print in that case?

Sometimes, on travis-ci, the last build on MacOS fails in configure.
It gets resolved if I restart the build with a minor comment merge.
This has happened twice now.
