MESH-1543: coverage bridge #979

#979

Refactor on UT of bridge pallet and it also add new ones to increase the coverage of this module.

1. handle_bridge_tx_now adds new argument exempted_did, which ignore the bridge limits if it is some. This allows to remove the "hacky approach" in force_handle_signed_bridge_tx line 853.
2. Move code outside decl_storage macro.
3. Remove some duplicated code.

More stuff

1. Genesis configuration has been moved out from lib.rs into genesis.rs.

3. ExtBuilder supports bridge configuration.

modified API

• Bridge::Event::TxsHandled added the recipient account to each handled transaction.

MESH-1603: allow portfolio custodians unilaterally quit #977

#977

new features

• A new extrinsic quit_portfolio_custody is added in the portfolio module to allow a portfolio custodian to relinquish custodianship duties without going through the authorization sequence.

modified logic

• Accepting a portfolio custody authorization for the portfolio owner will not add the pair of portfolio owned and the portfolio ID to the PortfoliosInCustody mapping in the portfolio module.
• The portfolio name length parameter was removed from the weight of the create_portfolio extrinsic in the portfolio module.

MESH-1598: use expect/assert in benchmarks #986

#986

Changed all ? operators in the benchmarks to unwrap() and changed all ensure's to assert.

MESH-1617: Fixed a bug preventing some operators from changing commission #987

#987

MESH-1593: Fix payout_stakers benchmarks #988

#988

MESH-1542: Improve code coverage for Identity module #990

#990

MESH-1581: External Agents #978

#978

new features

• The ExternalAgents pallet has been added. The functionality is described more thoroughly in the code documentation. As a result, many things noted below, on a best-effort basis, have changed, including extrinsics, schema, events, error types, and some data types.
• Types AgentGroup and AGId have been added.

modified API

• SubsetRestriction (i.e. ExtrinsicPermissions & friends) is now redefined as either Whole, These(elems), and Except(elems).
• TargetIdentity::PrimaryIssuanceAgent is now TargetIdentity::ExternalAgent, testing for if the identity is any of the external agents.
• AuthorizationData::BecomeAgent(Ticker, AgentGroup) was added. This authorization is used for adding an external agent with a group to an asset. Similarly, AuthorizationType::BecomeAgent was added.
• AuthIdentifier was removed. It was never actually in use.
• Extrinsics CorporateActions::reset_caa, Asset::remove_primary_issuance_agent, and Asset::accept_primary_issuance_agent_transfer have been removed.
• The error IrrelevantAuthorization (Portfolio pallet) was removed.
• CorporateActions::Agent (storage item) was removed.
• SecurityToken.primary_issuance_agent was removed.
• SecondaryKeyNotAuthorizedForAsset was moved to the external agents pallet.

modified logic

• Relevant extrinsics now check for agent permissions. Sometimes, this replaces other explicit checks such as from the explicit CAA or PIA concepts.
• AuthorizationData::{TransferPrimaryIssuanceAgent, TransferCorporateActionAgent} are now always rejected by the chain. That is, these variants are deprecated awaiting future removal.

MESH-1587: move Alcyone & general genesis identity balances to the bridge #966

#966

modified logic

• Genesis identities in dev and testnet configurations are changed a bit to more closely resemble the ITN config.

MESH-1623: add memo field to portfolio #1004

#1004

new features

• Add optional memo field to portfolio.move_portfolio_funds. Each asset moved can have a memo added to the move.

modified API

• Add memo field (Option<Memo>) to MovePortfolioItem struct.
• Add memo field to MovedBetweenPortfolios event.

modified logic

• Each asset that is moved between portfolios can have a memo attached to the move action.

MESH-1620: refactor #1011

#1011

This is a refactor of the batch functions in the utility pallet. No logic was changed. The main goal is to decrease duplicate code.

ExternalAgents: Fix schema + fn agent_permissions #1012

#1012

modified API

• Fixed bug in schema, Meta -> ExceptMeta

modified logic

• Fixed bug in fn agent_permissions for ExceptMeta

MESH-1619: Allow rescheduling failed Settlements #996

#996

new features

• Event InstructionRescheduled
• Errors InstructionNotFailed and UnknownInstruction
• Extrinsic Settlement::reschedule_instruction

modified API

• Settlement::reject_instruction only takes instruction_id as an argument

modified logic

• Instructions are no longer pruned upon failure and instead go into a Failed state.

MESH-1621: Script to create snapshot of all user balances #1000

#1000

Created a script to get users balances and store them in a CSV file.

#1003

new features

• batch functions return number of events emitted from each call.

modified API
