closes: #7101
polkadot companion: paritytech/polkadot#3407

Features

  • Support multiple vesting schedules per account. Each account is allowed up to MaxVestingSchedules, which is a configurable pallet constant.
  • A user can merge two schedules together to create a new schedule. See the new merge_schedules extrinsic

Follow up work

  • Look into adding a vesting derive to polkadot-js that helps with understanding the affects of merging a schedule

TODO:

  • make sure all instances of per_block are replace with One::one if it equals 0. (pallet-vesting: Support multiple, merge-able vesting schedules #9202 (comment))
  • weights
  • polkadot companion
  • migration (check if any faulty schedules exist in polkadot)
  • make sure tests cover (checked everything expect still need to figure out how force invalid vec length)
    • all dispatcherror paths are checked as noop <-- (a lot, and its important)
      • max length
      • validation of input ✔️
      • etc
    • shows single vesting is working just like before ✔️
    • shows multiple vesting works as expected ✔️
      • as a vesting ends, the vec is auto cleaned up
      • the last assertion at the end of N blocks is that the user has no vesting storage item left ✔️
    • merges two ongoing vesting schedules ✔️
    • merges one ended and one ongoing schedule ✔️
    • merges two ended schedules ✔️
    • merge ongoing and yet to be started schedule ✔️
    • merge ended and yet to be started schedule ✔️
    • merge 2 not yet started schedules ✔️
    • Check div by zero ✔️
