When creating an existing bucket with s3cmd, the return code is not BucketAlreadyExists.
~# s3cmd ls
2017-12-15 06:37 s3://lyb <---------------------- bucket is exist
2017-12-21 01:46 s3://myz
~# s3cmd mb s3://lyb
Bucket 's3://lyb/' created <---------------------- the creation success
dig into the code, the ERR_BUCKET_EXISTS is modified to zero in function send_response.
2570 void RGWCreateBucket::execute()
2571 {
. . .
2760 op_ret = rgw_link_bucket(store, s->user->user_id, s->bucket,
2761 info.creation_time, false);
2762 if (op_ret && !existed && op_ret != -EEXIST) {
2763 /* if it exists (or previously existed), don't remove it! */
2764 op_ret = rgw_unlink_bucket(store, s->user->user_id, s->bucket.tenant,
2765 s->bucket.name);
2766 if (op_ret < 0) {
2767 ldout(s->cct, 0) << "WARNING: failed to unlink bucket: ret=" << op_ret
2768 << dendl;
2769 }
2770 } else if (op_ret == -EEXIST || (op_ret == 0 && existed)) {
2771 op_ret = -ERR_BUCKET_EXISTS; <-------------------------------------------- the return code is set to ERR_BUCKET_EXISTS
2772 }
1193 void RGWCreateBucket_ObjStore_S3::send_response()
1194 {
1195 if (op_ret == -ERR_BUCKET_EXISTS) <-------------------------------------------- ERR_BUCKET_EXISTS is changed to 0
1196 op_ret = 0;
Is anyone know the reason that ERR_BUCKET_EXISTS is modified to zero? Thanks.
