Additional Information

Version of s3fs being used (`s3fs --version`)

V1.92 (commit:unknown) with OpenSSL

Version of fuse being used (`pkg-config --modversion fuse`, `rpm -qi fuse` or `dpkg -s fuse`)

Kernel information (`uname -r`)

GNU/Linux Distribution, if applicable (`cat /etc/os-release`)

How to run s3fs, if applicable

/root/s3fs-fuse-1.92/src/s3fs test-list /mnt/test -o passwd_file=/root/aksk -o url=https://obs.cn-south-1.myhuaweicloud.com -o compat_dir

s3fs syslog messages (`grep s3fs /var/log/syslog`, `journalctl | grep s3fs`, or `s3fs outputs`)

Details about issue

mkdir /mnt/test/b (/mnt/test is the MOUNTPOINT)
touch /mnt/test/b/file
Then use SDK to create a object named /ab/cd.

(There should be 3 objects in the backend storage server, /b, /b/file and /ab/cd.)

At last, readdir to the mountpoint root directory, the result expects to be b and ab, BUT it only shows b.

I did some more testing, and found that if I remove /b/file, the readdir result becomes correct.

@hbao0915
Around v1.91, the handling of objects created from SDKs other than s3fs is slightly different.(These are related to the compat_dir option, etc.)
s3fs performs processing to detect objects (including directory paths) created with SDK(aws CLI), etc.

If possible, try using the code from the master branch or restarting it with the compat_dir option.
With the current master code, this issue seems to have been resolved.
