[OT] how does "git review --setup" figure out my username?

[OT] how does "git review --setup" figure out my username?

[Robert P. J. Day]

  (technically not a git question, but i kind of need to know the
answer to this quickly as i'm writing some documentation and this is
something i have to explain.)

  i cloned a repository (hyperledger fabric) which has a top-level
.gitreview file:

  [gerrit]
  host=gerrit.hyperledger.org
  port=29418
  project=fabric

and, as i read it, if i want to configure to use gerrit, an initial
invocation of "git review --setup" should do that for me, which it
appears to do, as it adds the following to .git/config:

  [remote "gerrit"]
        url = ssh://rpjday@gerrit.hyperledger.org:29418/fabric
        fetch = +refs/heads/*:refs/remotes/gerrit/*

and copies over the commit-msg hook. so far, so good.

  but from where does it figure out the username (rpjday) to use when
configuring that remote? i have no gerrit configuration in my
.gitconfig file. however, i have configured gerrit at the hyperledger
end to use my SSH key, which is associated with my linux foundation ID
(rpjday) that i registered to start using that repo.

  is that where it gets the username from?

I've never used gerrit, but from my skimming of
https://www.mediawiki.org/wiki/Gerrit/git-review#Setting_up_git-review
and https://www.mediawiki.org/wiki/Gerrit/Tutorial#Configuring_git-review
it seems (to me) to say that it simply tries if your local loginname
works on the remote. Is rpjday your loginname on this system?

  yes, but it's just a fluke that i used the same user name in both
places ... what if i hadn't? which one would it have selected?

Seems like a fairly common case, especially as gerrit tends to be used
in Big Corp setups where your username is the same.

According to the docs I linked to it'll ask you if it doesn't happen to
match, but as I've said never used it, and that may be wrong.
