Until #57 is ready, ls on the bucket is fetching the full listing of all keys and their details (98k files), which might take longer than some FUSE timeout.
@asford , are you planning on working on file listing?

I am adding more logging in #67 and any further improvements. In this case, I don't think it would tell you more than that the directly listing had started.

#57 includes optimization of the directory listing codepath, so the ls time should be proportional to the number of files in the directory.
@mrocklin I've rebased that pull against the release revision. Would it be possible for you to quickly test git+https://github.com/asford/gcsfs@per_dir_cache in that install to see if it resolves your issue?

Sure. Here is an attempt from that branch
mrocklin@carbon:~/workspace/gcsfs$ git checkout per_dir_cache
Branch per_dir_cache set up to track remote branch per_dir_cache from asford.
Switched to a new branch 'per_dir_cache'
mrocklin@carbon:~/workspace/gcsfs$ python gcsfs/cli/gcsfuse.py pangeo-data gcs
Mounting bucket pangeo-data to directory gcs

Also, fwiw that bucket is publicly readable. You should be able to do the same thing locally if you're interested.

Great, thanks. This is likely due to a mismatch in how objects & prefixes are matched to files & directories in that patch.
Is there any intention to lift the gcsfuse implementation into a generic interface support s3fs?

commented on June 12, 2024
@asford , we certainly could implement the same model of fuse for s3fs, and this idea has been mentioned; but there are already several projects around that do that for s3, which may be good enough.
