  • Support ec parent filter for Search

Proprely choose root OID for EC-splitted objects:

  • If EC-parent is a part of Split itself, then save to root bucket its parent (if it is not nil);
  • If EC-parent is not a part of Split itself, then save to root bucket OID of this EC-parent.

The container is created with EC-policy:

frostfs-cli container create -r s01.frostfs.devenv:8080 --wallet wallet.json --await --policy 'EC 3.1 CBF 1' --basic-acl 0

Let's make search with --root

frostfs-cli object search -r s01.frostfs.devenv:8080 --wallet wallet.json --cid G6zyDxdkyWhboZq12j8CbZBHVMRGPPjRnt6z3zLeaQQu --root

ROOT

Search with --root should return only user objects.
If an object is small, then EC-parent's OID must be listed.
If an object is big, then the object is Split-ted, and then the parts of Split are EC-splitted. That means, then no EC-parent is listed but only the last part of Split (user object)

frostfs-cli object put -r s01.frostfs.devenv:8080 --wallet wallet.json --cid 4SJMJNPC4jCVwJBFwzc1SKYqXJCpX8u8yCjmBdsyWQke --file big_object

Output:

OID: 79xGoKYwhyJQhrDNb7bHhY1WCvN6trHJPTjKkw24c6W9
CID: 4SJMJNPC4jCVwJBFwzc1SKYqXJCpX8u8yCjmBdsyWQke

Let's search with --root

frostfs-cli object search -r s01.frostfs.devenv:8080 --wallet wallet.json --cid 4SJMJNPC4jCVwJBFwzc1SKYqXJCpX8u8yCjmBdsyWQke --root

Output:

Found 1 objects.

Putting small object

frostfs-cli object put -r s01.frostfs.devenv:8080 --wallet wallet.json --cid 4SJMJNPC4jCVwJBFwzc1SKYqXJCpX8u8yCjmBdsyWQke --file random_binary_small

frostfs-cli object search -r s01.frostfs.devenv:8080 --wallet wallet.json --cid 4SJMJNPC4jCVwJBFwzc1SKYqXJCpX8u8yCjmBdsyWQke --root

Output

79xGoKYwhyJQhrDNb7bHhY1WCvN6trHJPTjKkw24c6W9 # Split
AM5Kx5QnsnbUHHLW37xWiPszn6eTd45irx28vcSqcZjE # EC-parent

Filter ec.parent

frostfs-cli object put -r s01.frostfs.devenv:8080 --wallet wallet.json --cid 7ygY2uqM6eVwBaaM2K3wNn9A434FhnUQEavRA2CDbgKj --file random_binary_small

Output:

OID: AgFKsq3AUbCRw7Dz6nuDBGUHZMkWw36sfBFH4V5YMxJK
CID: 7ygY2uqM6eVwBaaM2K3wNn9A434FhnUQEavRA2CDbgKj

Then

frostfs-cli object search -r s01.frostfs.devenv:8080 --wallet wallet.json --cid 7ygY2uqM6eVwBaaM2K3wNn9A434FhnUQEavRA2CDbgKj --filters '$Object:ec.parent EQ AgFKsq3AUbCRw7Dz6nuDBGUHZMkWw36sfBFH4V5YMxJK'

Output (EC-chunks with this EC-parent):

Am I right that this bucket will be removed automatically here?

We can probably reuse the slice in the second argument, no?
