Why this change?
|

|

Looking at Metadata (https://github.com/scality/MetaData/blob/22bd001394a7c706556fcdf89821859e96ac7a2a/lib/server/VersioningRequestProcessor.js#L334) and MongoClientInterface (https://github.com/scality/Arsenal/blob/development/8.1/lib/storage/metadata/mongoclient/MongoClientInterface.js#L772)..
|
||||
|
||||
An isPHD version is created to temporarily replace current
|
||||
master version with a PHD.
|
||||
|
||||
Also, (correct me if I'm wrong) I only see an isPHD created for
|
||||
objects only (not buckets).
|
||||
|
||||
So, this would mean running into a PHD version during the
|
||||
skip-scan delimiterMaster, we should treat the next version
|
||||
after a PHD as the expected master version.
|
||||
|
||||
In the case I'm trying to address now, when listing master
|
||||
versions, we want to exclude delete markers from the listing.
|
||||
Setting `this.prvKey` here will mean any following versions or
|
||||
delete markers that have the same `key` name will be filtered
|
||||
above, returning FILTER_SKIP. (Line #76 - `key === this.prvKey`)
