Hi all,

I had those messages today

  % git merge origin/master
    Already uptodate!
    Merge made by recursive.
  %

with git version 1.7.2.rc1.210.g7b476 and I wonder if it is really
intended.  It did create an empty merge commit but I find both messages
together a bit confusing here.  Why would Git merge if uptodate?

I don't think I will have time to investigate in the comming weeks but
you should be able to reproduce it by following these steps (it is by
now, at least):

  % git clone git://github.com/nvie/gitflow.git
  % cd gitflow
  % git merge origin/master
  %

Thanks,

This is quite an old message; I don't think it has much to do with 1.7-ness
of your version.

The first "uptodate" refers to your tree state being up-to-date.  You
already had the necessary changes the other history wanted you to
have---they were acquired in your history before you started this merge by
some other means.  Perhaps merging from other trees, or picking up
equivalent patches from mailing list, etc.

A merge commit is still created in this case, in order to record the fact
that everything origin/master wanted to do to your history has already
been reconciled to your history.  Otherwise "git log ..origin/master" will
still show commits your history does not have.

This is what I was guessing but wanted to be sure that the resulting

In any case, "uptodate" should be written as "up-to-date" for consistency with other user-visible messages in Git and in the docs.

Did you run the tests after applying this patch? This looks like it would break:

t/t7110-reset-merge.sh
176:    grep file1 err.log | grep "not uptodate"
192:    grep file1 err.log | grep "not uptodate"

What word do you see before "errors" on the hunk comment line?

So you'd rather not touching it? Or wait until the next release cycle?
Or a better commit message? Anything else?

Well, "'d rather" is actually too weak a statement.

The "struct unpack_trees_error_msgs" mechanism was introduced so that we
can change the Porcelain level messages without breaking the plumbing API,
which these messages are part of.  Please see 8ccba00 (unpack-trees: allow
Porcelain to give different error messages, 2008-05-17) and fadd069
(merge-recursive: give less scary messages when merge did not start,
2009-09-07) for backstory.

Oh, thanks. I was unaware of this mechanism and didn't care about what I was
touching.

I suspect that the documentation patch talks about a nonexistent reality.
See 8ccba00 again ;-)

Doh! You said in this commit that

	"If you do not see something wrong with this output, your brain has already
	been rotten with use of git for too long a time."

but I claim the right to be rotten in much more ways. :-)

Sorry, but the pros-and-cons is not good enough for me to support this
change.  It will break users who have been parsing output with scripts.

We do strongly warn people against relying on Porcelain output, but that
does not mean we are free to change them without having a good reason or
two.  The new spelling won't help the next reader who will find the
message confusing the same way you did a few days ago.

IOW, if we are touching this line anyway, I'd like to make sure we made an
effort to make it less confusing, not just spelled correctly, while we
still have our memory of confusion fresh ;-)
