this is for csm to use? i. e., when the value/type of err is related to candidate error

i mean, it will return a regular err, not the handleError you may want

should return regular err here, b/c the error returned must be some unknown errors from db

what's the case for a regular (not self-stake) endorsed bucket?

It expire immediately if the bucket is not self-staked, otherwise, expire after unendorse waiting period. Also added code comments for this

+ if err := validateBucketOwner(bucket, caller); err != nil {


no need to check other conditions?

The two checks should be enough:

only bucket owner is authorized

bucket should be endorsed

this part is the same, can move to common end

uint64 expireHeight if act.Endorse() { xxx expireHeight = endorsementNotExpireHeight, } else { xxx expireHeight := protocol.MustGetBlockCtx(ctx).BlockHeight if csm.ContainsSelfStakingBucket(bucket.Index) { expireHeight += p.config.EndorsementWithdrawWaitingBlocks } } esm.Put(bucket.Index, &Endorsement{ ExpireHeight: expireHeight, }

+ BootstrapCandidates: []BootstrapCandidate{},
+ EndorsementWithdrawWaitingBlocks: 24 * 60 * 60 / 5,


what's the meaning of the value

After submitting the endorsement withdraw action, it takes the waiting blocks for it to take effect. During this period, the delegate can continue to participate in consensus, and the bucket is locked, meaning it cannot be unstaked or voted to others.
