This is the recommended approach for new targets as it provides robust control over token issuance through the IssuanceAllocator. + +2. **Self-minting allocation**: The IssuanceAllocator calculates issuance but does not mint tokens directly. Instead, targets call `getTargetIssuancePerBlock()` to determine their allocation and mint tokens themselves. This feature exists primarily for backwards compatibility with existing contracts like the RewardsManager. + +While targets can technically have both types of allocation simultaneously, this is not the expected configuration.

Because RewardsManager does not check `blockAppliedTo` and will mint tokens even when the allocator is paused, the initial implementation does not pause self-minting targets. (This behavior is subject to change in future versions, and new targets should check `blockAppliedTo`.) Note that RewardsManager is independently pausable. +- **Configuration allowed**: Governance functions like `setIssuancePerBlock()` and `setTargetAllocation()` still work.

It calculates issuance for all targets based on their configured proportions + * and handles minting for allocator-minting portions. + * + * @dev The contract supports two types of allocation for each target: + * 1. Allocator-minting allocation: The IssuanceAllocator calculates and mints tokens directly to targets + * for this portion of their allocation. + * + * 2. Self-minting allocation: The IssuanceAllocator calculates issuance but does not mint tokens directly. + * Instead, targets are expected to call `getTargetIssuancePerBlock` to determine their self-minting + * issuance amount and mint tokens themselves. This feature is primarily intended for backwards + * compatibility with existing contracts like the RewardsManager. + * + * Each target can have both allocator-minting and self-minting allocations. New targets are expected + * to use allocator-minting allocation to provide more robust control over token issuance through + * the IssuanceAllocator. The self-minting allocation is intended only for backwards compatibility + * with existing contracts. + * + * @dev There are a number of scenarios where the IssuanceAllocator could run into issues, including: + * 1. The targetAddresses array could grow large enough that it exceeds the gas limit when calling distributeIssuance. + * 2. When notifying targets of allocation changes the calls to `beforeIssuanceAllocationChange` could exceed the gas limit. + * 3. Target contracts could revert when notifying them of changes via `beforeIssuanceAllocationChange`. + * While in practice the IssuanceAllocator is expected to have a relatively small number of trusted targets, and the + * gas limit is expected to be high enough to handle the above scenarios, the following would allow recovery: + * 1. The contract can be paused, which can help make the recovery process easier to manage. + * 2. The GOVERNOR_ROLE can directly trigger change notification to individual targets. As there is per target + * tracking of the lastChangeNotifiedBlock, this can reduce the gas cost of other operations and allow + * for graceful recovery. + * 3. If a target reverts when notifying it of changes or notifying it is too expensive, the GOVERNOR_ROLE can use `forceTargetNoChangeNotificationBlock()` + * to skip notifying that particular target of changes. + * + * In combination these should allow recovery from gas limit issues or malfunctioning targets, with fine-grained control over + * which targets are notified of changes and when. + * @custom:security-contact Please email security+contracts@thegraph.com if you find any bugs.
