mkmf submodule broken for ESM4 / OMIP tag

jkrasting commented 6 years ago

The mkmf submodule no longer checks out using the tag dev/gfdl/2018.04.11. The error message is:

error: Server does not allow request for unadvertised object 309d50df87a455337ec3c9bd6d0f43ede348e0c6
Fetched in submodule path 'src/mkmf', but it did not contain 309d50df87a455337ec3c9bd6d0f43ede348e0c6. Direct fetching of that commit failed.

Here are the checkout commands:

git clone https://github.com/NOAA-GFDL/MOM6-examples.git
cd MOM6-examples/
git checkout dev/gfdl/2018.04.11
git submodule init
git submodule update --recursive

And the output:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 192fb89b... Merge branch 'jkrasting-user/jpk/OM4_05_remap_overrides' into dev/gfdl

@adcroft and @underwoo - I see the mkmf repo was updated a few days ago. Did something go awry with the repo?

underwoo commented 6 years ago

Nothing changed. Just some cleanup.

jkrasting commented 6 years ago

Are you able to replicate this? Any idea why git can no longer checkout this specific commit? It seems that the mkmf directory is empty, except for the .git directory. --

I can reproduce your problem.

Commit NOAA-GFDL/mkmf@309d50df87a455337ec3c9bd6d0f43ede348e0c6 does still exist (click the link).

However, that commit used to be on a branch "find.symlinks" which has been deleted. From an older clone:

git log --oneline ..origin/find.symlinks
309d50d Better fix for symlinks
8895cac list_paths now finds symlinks as well

That branch was clearly not merged because the commit is not in the history for the sole remaining branch "master":

$ git log --oneline
e22242f New template for Travis-CI (#16)
e746b66 Version 19.3.0 (#15)

I suspect that only commits on branches are being downloaded during the clone.

@underwoo For the interim, I think we need you to restore the branch since tagged models point to it. I'll make a list of any commits you asked us to use that are not on "master". Somehow we need to find a way to get that commit into the history, perhaps by reverting it on the find.symlinks branch and then merging the branch as a no-op?

underwoo commented 6 years ago

Commit/branch restored.

jkrasting commented 6 years ago

Back to normal again.

Thanks @underwoo and @adcroft! --
