ah, got it. Still some of my concerns stay valid and I also have some
new ones:
- if there is a branch and a tag on the remote side that match what I
specified the outcome depends on the order of git-ls-remote. (minor
nit.)
- if I have to specify the remote name now, why do I have to also
specify my local ref? Isn't the respective $sha1 of the remote side
enough to do what is needed?
- Isn't $found = $sha1; silly because I cannot pull a rev, only a ref?
(side note:
git pull linus d91d66e88ea95b6dd21958834414009614385153
gives no error message, only returns 1 and does nothing else.)
- Is the result of
git request-pull $somecommit origin
what is intended? For me it does
...
are available in the git repository at:
$repository
for you to fetch changes ...
if the remote HEAD matches the local one. I'd prefer to have an
explicit branch name there, or at least HEAD.
I liked git guessing the branch name, maybe we can teach it to guess a
bit better than it did before 2.0? Something like:
- if there is a unique match on the remote side, use it.
- if there are >= 1 match on the remote side and exactly one matches
what I specified as <end>, use it.
- if there are >= 1 match on the remote side and exactly one of them is
a tag, use the tag
- if there are two matches on the remote side, and one is "HEAD",
pick the other one.
Best regards
Uwe
