func (Keeper) AllocateAcrossGauges 

func (k Keeper) AllocateAcrossGauges(ctx sdk.Context, activeGroups []types.Group) error

AllocateAcrossGauges for every gauge in the input, it updates the weights according to the splitting policy and allocates the coins to the underlying gauges per the updated weights. Note, every group is associated with a group gauge. The distribution to regular gauges happens from the group gauge. Returns error if: - fails to retrieve a group gauge - fails to add gauge rewards to any of the underlying gauges in the group.

Silently skips the following errors: - syncing group gauge weights fails - this is acceptable. We don't want to fail all distributions due to an oddity with one group. The rewards should stay in the group gauge until the next distribution. Any issues can be fixed with a major upgrade without any loss of funds. - group gauge is inactive - similar reason, don't want to fail all distributions due to non-fatal issue.

ASSUMPTIONS: - group cannot outlive the gauges associated with it. CONTRACT: - every group in the input is active. If inactive group is passed in, it will be skipped.

func (Keeper) CreateGauge 

func (k Keeper) CreateGauge(ctx sdk.Context, isPerpetual bool, owner sdk.AccAddress, coins sdk.Coins, distrTo lockuptypes.QueryCondition, startTime time.Time, numEpochsPaidOver uint64, poolId uint64) (uint64, error)

CreateGauge creates a gauge with the given parameters and sends coins to the gauge. There can be 3 kinds of gauges for a given set of parameters: * lockuptypes.ByDuration - a gauge that incentivizes one of the lockable durations. For this gauge, the pool id must be 0. Fails if not.

* lockuptypes.NoLock - a gauge that incentivizes pools without locking. Initially, this is meant specifically for the concentrated liquidity pools. As a result, if NoLock gauge is being created, the given pool id must be non-zero, the pool at this id must exist and be of a concentrated liquidity type. Fails if not. Additionally, lockuptypes.Denom must be either an empty string, signifying that this is an external gauge, or be equal to types.NoLockInternalGaugeDenom(poolId). If the denom is empty, it will get overwritten to types.NoLockExternalGaugeDenom(poolId). This denom formatting is useful for querying internal vs external gauges associated with a pool. * lockuptypes.Group - a gauge that incentivizes a group of internal pool gauges based on the splitting policy created by a group data structure. It is expected to be created via CreateGroup keeper method. This gauge is the only gauge type that does not have ref keys (active/upcoming/finished) created and associated with it. For this gauge, the pool id must be 0. Fails if not.

Returns error if: - attempts to create non-perpetual gauge with numEpochsPaidOver of 0

On success, returns the gauge ID.

func (Keeper) CreateGaugeRefKeys 

func (k Keeper) CreateGaugeRefKeys(ctx sdk.Context, gauge *types.Gauge, combinedKeys []byte) error

CreateGaugeRefKeys takes combinedKey (the keyPrefix for upcoming, active, or finished gauges combined with gauge start time) and adds a reference to the respective gauge ID. If gauge is active or upcoming, creates reference between the denom and gauge ID. Used to consolidate codepaths for InitGenesis and CreateGauge.

func (Keeper) CreateGroup 

func (k Keeper) CreateGroup(ctx sdk.Context, coins sdk.Coins, numEpochPaidOver uint64, owner sdk.AccAddress, poolIDs []uint64) (uint64, error)

CreateGroup creates a new group. The group is 1:1 mapped to a group gauge that allocates rewards dynamically across its internal pool gauges based on the volume splitting policy. For each pool ID in the given slice, its main internal gauge is used to create gauge records to be associated with the Group. Note, that implies that only perpetual pool gauges can be associated with the Group. For Group's own distribution policy, a 1:1 group Gauge is created. This is the Gauge that receives incentives at the end of an epoch in the pool incentives as defined by the DistrRecord. The Group's Gauge can either be perpetual or non-perpetual. If numEpochPaidOver is 0, then the Group's Gauge is perpetual. Otherwise, it is non-perpetual. It syncs the group's weights at the time of creation. This is useful for validating that all the pools in the group are valid and have the associated volume at group creation time. Charges group creation fee, unless incentives module account. Returns nil on success. Returns error if: - given pool IDs slice is empty or has 1 pool only - fails to initialize gauge information for every pool ID - fails to send coins from owner to the incentives module for the Group's Gauge - fails to charge group creation fee - fails to set the Group's Gauge to state

func (Keeper) CreateGroupAsIncentivesModuleAcc 

func (k Keeper) CreateGroupAsIncentivesModuleAcc(ctx sdk.Context, numEpochPaidOver uint64, poolIDs []uint64) (uint64, error)

CreateGroupAsIncentivesModuleAcc creates a group as incentives module account. The group is 1:1 mapped to a group gauge that allocates rewards dynamically across its internal pool gauges based on the volume splitting policy. For each pool ID in the given slice, its main internal gauge is used to create gauge records to be associated with the Group. Note, that implies that only perpetual pool gauges can be associated with the Group. For Group's own distribution policy, a 1:1 group Gauge is created. This is the Gauge that receives incentives at the end of an epoch in the pool incentives as defined by the DistrRecord. The Group's Gauge can either be perpetual or non-perpetual. If numEpochPaidOver is 0, then the Group's Gauge is perpetual. Otherwise, it is non-perpetual. The group is created with empty coins. It does not sync weights at the time of creation. This is useful for creating groups of pools in a privileged way For example, in the upgrade handler. Use with care since it is possible to create a group of pools that are invalid (have no volume) due to lack of syncing. Stores the group to state. The group creation fee is not charged on the incentives module account. See other details of group creation by reviewing createGroup() spec. Returns group gauge ID on success. Returns error if: - fails to create Group

func (Keeper) Distribute 

func (k Keeper) Distribute(ctx sdk.Context, gauges []types.Gauge) (sdk.Coins, error)
