Hello,
Radosgw version Hammer (0.94.5) can not delete a null version key which
created before
turn on bucket versioning[1]. And its value can still be accessed. In
order to
solve this problem, I applied the changes of [2]. But sometimes the test
case
can pass, sometimes not.
For all my osd daemons, I set breakpoints at
rgw_bucket_unlink_instance/rgw_bucket_read_olh_log.
I noticed that a failed case's unlink/read_olh_log requests never
reached osd side.
How to fix this problem? Any suggestions?
Thx,
joseph

[1] How to reproduce the bug:
- create bucket
- put key AAA
- turn on bucket versioning
- read AAA // expect 404
- delete AAA
- delete bucket
