Remove breaking check about `auto_mkdir` for FSSpecStore by maxrjones · Pull Request #3193 · zarr-developers/zarr-python

maxrjones · 2025-07-02T12:51:52Z

This change is causing downstream breakages since auto_mkdir is only relevant for stores with read_only = False and stores that are in the root of the provided directory.

E.g., https://github.com/developmentseed/titiler/actions/runs/16025154840/job/45211163911#step:8:2093

This fixes a regression introduced in #2774. I apologize for the mistake in that pull request.

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

Checkout backport branch and update it.

git checkout 3.0.10
git pull

Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 5a24487f09d499c91ce25f24af910c2ede055b5a

You will likely have some merge/cherry-pick conflict here, fix them and commit:

git commit -am 'Backport PR #3193: Remove breaking check about `auto_mkdir` for FSSpecStore'

Push to a named branch:

git push YOURFORK 3.0.10:auto-backport-of-pr-3193-on-3.0.10

Create a PR against branch 3.0.10, I would have named this PR:

"Backport PR #3193 on branch 3.0.10 (Remove breaking check about auto_mkdir for FSSpecStore)"

And apply the correct labels and milestones.

This change is causing downstream breakages since auto_mkdir is only relevant for stores with read_only = False and stores that are in the root of the provided directory.

E.g., https://github.com/developmentseed/titiler/actions/runs/16025154840/job/45211163911#step:8:2093

This fixes a regression introduced in #2774. I apologize for the mistake in that pull request.

@meeseeksdev backport to 3.0.10

lumberbot-app · 2025-07-03T17:00:53Z

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

Checkout backport branch and update it.

git checkout 3.0.10
git pull

Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 5a24487f09d499c91ce25f24af910c2ede055b5a

You will likely have some merge/cherry-pick conflict here, fix them and commit:

git commit -am 'Backport PR #3193: Remove breaking check about `auto_mkdir` for FSSpecStore'

Push to a named branch:

git push YOURFORK 3.0.10:auto-backport-of-pr-3193-on-3.0.10

Create a PR against branch 3.0.10, I would have named this PR:

"Backport PR #3193 on branch 3.0.10 (Remove breaking check about auto_mkdir for FSSpecStore)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the Still Needs Manual Backport label once the PR gets merged.

If these instructions are inaccurate, feel free to suggest an improvement.

This change is causing downstream breakages since auto_mkdir is only relevant for stores with read_only = False and stores that are in the root of the provided directory.

E.g., https://github.com/developmentseed/titiler/actions/runs/16025154840/job/45211163911#step:8:2093

This fixes a regression introduced in #2774. I apologize for the mistake in that pull request.

@meeseeksdev backport to 3.0.10

lumberbot-app · 2025-07-03T17:00:53Z

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

Checkout backport branch and update it.

git checkout 3.0.10
git pull

Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 5a24487f09d499c91ce25f24af910c2ede055b5a

You will likely have some merge/cherry-pick conflict here, fix them and commit:

git commit -am 'Backport PR #3193: Remove breaking check about `auto_mkdir` for FSSpecStore'

Push to a named branch:

git push YOURFORK 3.0.10:auto-backport-of-pr-3193-on-3.0.10

Create a PR against branch 3.0.10, I would have named this PR:

"Backport PR #3193 on branch 3.0.10 (Remove breaking check about auto_mkdir for FSSpecStore)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the Still Needs Manual Backport label once the PR gets merged.

If these instructions are inaccurate, feel free to suggest an improvement.

This change is causing downstream breakages since auto_mkdir is only relevant for stores with read_only = False and stores that are in the root of the provided directory.

E.g., https://github.com/developmentseed/titiler/actions/runs/16025154840/job/45211163911#step:8:2093

This fixes a regression introduced in #2774. I apologize for the mistake in that pull request.

@meeseeksdev backport to 3.0.10

lumberbot-app · 2025-07-03T17:00:53Z

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

Checkout backport branch and update it.

git checkout 3.0.10
git pull

Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 5a24487f09d499c91ce25f24af910c2ede055b5a

You will likely have some merge/cherry-pick conflict here, fix them and commit:

git commit -am 'Backport PR #3193: Remove breaking check about `auto_mkdir` for FSSpecStore'

Push to a named branch:

git push YOURFORK 3.0.10:auto-backport-of-pr-3193-on-3.0.10

Create a PR against branch 3.0.10, I would have named this PR:

"Backport PR #3193 on branch 3.0.10 (Remove breaking check about auto_mkdir for FSSpecStore)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the Still Needs Manual Backport label once the PR gets merged.

If these instructions are inaccurate, feel free to suggest an improvement.
