Alliance pallet: retirement notice call #11970

muharem · 2022-08-03T15:21:00Z

Fixes #11936

Current implementation of retirement has a bug, which makes it impossible to retire for a member if there was a not enacted proposal to kick the member.

In the PR we introducing a new retirement_notice call, required to be executed by a member before retiring.
The notice will start a 'retirement period' that has to pass in order to retire.
The required period prevents a misbehaving member to retire before it will be kicked and slashed.

The PR does not cover next use cases:

if alliance does not execute the voted proposal to kick a misbehaving member, the member can retire without being slashed;
a member can not revoke the retirement process if retirement notice was given. It must retire and join alliance again if desires;

@@ -1537,6 +1539,7 @@ parameter_types! {
 	pub const MaxFellows: u32 = AllianceMaxMembers::get() - MaxFounders::get();
 	pub const MaxAllies: u32 = 100;
 	pub const AllyDeposit: Balance = 10 * DOLLARS;
+	pub const RetirementPeriod: BlockNumber = ALLIANCE_MOTION_DURATION + (1 * DAYS);


This is fine in the node template but when we introduce a Root call to force dissolve the Alliance, we should make this longer than the root voting period.

Adding a bit to this, I think it's OK for the retirement period to be really long (e.g. >3 months). We expect Alliance members to be quite committed to the network and they shouldn't retire just because they want to unreserve their DOT the way that someone might unbond their DOT.

+	pub type RetiringMembers<T: Config<I>, I: 'static = ()> =
+		StorageMap<_, Blake2_128Concat, T::AccountId, T::BlockNumber, OptionQuery>;


Mostly just curious, why not store this in the MemberRole variant itself (i.e. Retiring(T::BlockNumber))? I'm not sure if we have FRAME guidance on which is more idiomatic or when one method is better than another for a given use case (@kianenigma or @shawntabrizi ?).

A storage item makes it easier for UIs to query all retiring members, but they could also periodically just check all the members and build that info from there.

Right now there is one storage map to store all members, where the key is a member role and value is map of AccountIds (Members).
And this additional map to store the BlockNumber for retirement period.

saturating_add might be a good idea here just to be safe as @bkontur mentioned above.

Mostly looks good, but needs some minor fixes for clarity it seems.

lgtm,
I would just vote for renaming those two constants:
MOTION_DURATION -> MOTION_DURATION_IN_BLOCKS
ALLIANCE_MOTION_DURATION -> ALLIANCE_MOTION_DURATION_IN_BLOCKS
