Proposal 137499 – LaCosta | CodeGov

Vote: ADOPT

Governance Canister

Reason:
Build successful and hashes match, commits look great and match the description. Found no issues.

[b6696ce01a]: Adds a new metric governance_voting_power_snapshots_time_since_latest_snapshot_seconds

[02763b874b]: Updates error messages in FulfillSubnetRentalRequest::validate and implements a test for this method.

[758347643c]: Adds a new method register_extension which is controlled by both the Root and Governance canister of the particular SNS. This method allows SNSs to register canister extensions, for a look into what this could look like, the first SNS extensions proposed is a SNS Liquidity Pools extension.

[3206a4ba77]: Updates change logs to include adopted proposals and corresponding changes.

Proposal 137500 – LaCosta | CodeGov

Vote: ADOPT

Registry Canister

Reason:
Build successful and hashes match, commits look great and match the description. Found no issues.

Contains duplicate commits from previous proposals

[c9bc66d60d]: Updates the MISSING_NODE_TYPES_MAP

[054b2e32d7]: Adds multiple benchmarks for canister migration

[f0e6f87a89]: Removes depecrated EcdsaConfig

[28f77acbda]: Removes the condition if !shards.is_empty() that pre migration allowed check_routing_table_invariants to skip the assertion betwenn the 2 routing table formats, rt_from_shards and rt_from_routing_table_record.

Commits Summary

proposal/137499 (Governance)

b6696ce01a
4 modified

Fixed voting power snapshots to capture not just latest_snapshot_is_spike but also latest_snapshot_timestamp_seconds. New metric governance_voting_power_snapshots_time_since_latest_snapshot_seconds. Refactor bench voting_power_snapshots_is_latest_snapshot_a_spike into two functions set_up_snapshots and populate_snapshots which are then used in the benches.

validate method now checks if the collected defects vector is non-empty. If so, it constructs and returns a single GovernanceError that includes all validation issues concatenated into one message.

758347643c
12 modified

Support for extension canisters in the SNS Root, which are similar to dapp canisters but are controlled by both the Root and Governance canisters and are listed separately in responses like ListSnsCanistersResponse. A new API method register_extension is added to register these canisters, with validation to ensure proper controllers, prevent duplicates or overlaps with dapps/SNS canisters, and enforce a combined registration limit of 100 for dapps and extensions.

Update change logs.

New set of MISSING_NODE_TYPES_MAP.

Single-entry routing table retrieval and comparison with the sharded routing table are skipped. Addition of performance benchmarks for routing table operations (canister migrations, upgrades, and subnet lookups).

f0e6f87a89
8 modified

Removes the EcdsaConfig message from the subnet protobuf definitions and the use of ChainKeyConfig instead. It updates the protobuf generator to eliminate specific type attributes for EcdsaConfig.

28f77acbda

Removes !shards.is_empty() check, sicne now shards are never empty. Clean up.

Proposal 137499 | Tim - CodeGov

Vote: Adopt

Reason: This proposal upgrades the Governance canister. Build is successful, hashes match, commits match descriptions and the reasoning behind the changes is sound. Commits are reviewed below.

[b6696ce01a]
Splits the existing voting_power_snapshots_is_latest_snapshot_a_spike benchmark into voting_power_snapshots_is_latest_snapshot_a_spike_false and voting_power_snapshots_is_latest_snapshot_a_spike_true, adds voting_power_snapshots_latest_snapshot_timestamp_seconds benchmark and adds a new metric governance_voting_power_snapshots_time_since_latest_snapshot_seconds.

[02763b874b]
Adds test_validate_fulfill_subnet_rental_request and rewords some error messages in FulfillSubnetRentalRequest::validate.

[758347643c]
Adds update method register_extension to the SNS Root canister. Controllers for an extension canister are set exclusively as the root and governance canisters of the SNS, so long as the root canister is already a controller.

[3206a4ba77]
Updates changelog files.

Proposal 137500

Vote: Adopt

Reason: This proposal upgrades the Registry canister. Build is successful, hashes match, commits match descriptions and the reasoning behind the changes is sound. Commits are reviewed below.

[c9bc66d60d]
Updates MISSING_NODE_TYPES_MAP with a new set of mappings.

[3206a4ba77]
Reviewed above.

[054b2e32d7]
Adds new benchmarks, 3 for each of get_subnet_for_canister_100_times_..., migrate_canisters_10_times_... and upgrade_with_routing_table_... so as to test for 100, 1000 and 10000 canister migrations. Adds flag is_routing_table_single_entry_obsolete. These are then implemented as outlined in the commit notes.

[f0e6f87a89]
Removes EcdsaConfig type (defined separately in various code sections) as this has now been superseded by ChainKeyConfig.

[28f77acbda]
Removes the condition if !shards.is_empty() (i.e. if shards isn’t empty) from the equality check between routing tables from shards and routing table record. Modifies routing table tests so that they now make use of the canister ranges key to prepare shards.
