Vladimir and Ondřej,
Created a quincy backport PR:
https://github.com/ceph/ceph/pull/51300
Hopefully it would land in the next quincy release.

Hi Yuval,
Playing with Lua, I faced similar issue.
It would be perfect if you can backport this fix to Quincy.
Thank you!
Vladimir.

Hi Ondřej,
Greater to hear that you use lua. You are right, this field has become
writable only in reef.
I can backport the fix to quincy, so that you can use it in the next quincy
release (not sure when it is).
A better option would be to allow setting the failure from lua - but this
would be a new feature, that would probably land post reef.

Hello,
Lately I’ve been playing with Lua scripting on top of RGW.
I would like to implement a request blocking based on bucket name -> when
there is a dot in a bucket name return error code and a message that this
name is invalid.
Here is the code I was able to came up with.
if string.find(Request.HTTP.URI, '%.') then
Request.Response.HTTPStatusCode = 400
Request.Response.HTTPStatus = “InvalidBucketName"
Request.Response.Message = “Dots in bucket name are not allowed."
end
This works fine, but the request for creating a bucket would be processed
and the bucket will be created. I thought about a dirty workaround with
setting the Request.Bucket.Name to a bucket that already exists but it
seems that this field is not writable in Quincy.
Is there a way to block the request from processing?
Any help is much appreciated.
Kind regards,
Ondrej
