github-actions[bot]’s stale review
- Done.
- Only in the usual sense: now, there is a new NnsFunction: in order for clients to make sense of the payload, they need to make code changes. OTOH, Candid libraries will decode just fine, even without code changes.
- Existing data is fine. No new requirements.
- Requesting review of broader feature, but for this PR, all is ok, since this feature is disabled by flag.
… this commit does is introduces the (canister) API and storage types. Disabled via flag; hence, this can be merged into master.
…t into a TakeCanisterSnapshotRequest.

This most introduces the (canister) API and storage (Protocol Buffer) types. Disabled (in production) via a flag.
The other small thing this does is basic validation of the payload. The validation just consists of making sure that it can be decoded as a TakeCanisterSnapshotRequest. One can imagine that further checks being performed, but due to technical limitations (namely, changing functions to async), such checks are not so straightforward.
Nothing has been done yet on execution of such proposals, but since this is an NnsFunction, maybe there is nothing left to do.
Previous Work
In the previous PR, the Root canister was given a new method named
take_canister_snapshot, and that is where the (main) implementation of this new proposal type lives.Future Work
If there are Governance canister changes that are needed to execute this type of proposal, they'll be made in future changes. If not, I guess we can proceed directly to writing an integration test.
