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
