Remove Poly(to-Starcoin) Tx. blocking process

Set a poly_tx row's status to 'TBR'(To Be Removed):

update poly_tx set status = 'TBR' where tx_index = {TX_INDEX};

The scheduled tasks will check it, if suitable, remove it from poly_tx table and backup to removed_poly_tx table.

Check removed_poly_tx table:

select id, origin_tx_index, from_chain_id, poly_tx_hash, smt_non_membership_root_hash, status, starcoin_tx_hash from removed_poly_tx order by id desc limit 10;

Push removed Poly(to-Starcoin) Tx. back to process

Set a removed_poly_tx row's status to 'TBP'(To Be Pushed-back):

update removed_poly_tx set status = 'TBP' where id = {ROW_ID};

The scheduled tasks will remove it from removed_poly_tx table and push back to poly_tx table.

Check poly_tx table:

select tx_index, from_chain_id, poly_tx_hash, smt_non_membership_root_hash, status, retry_count, starcoin_tx_hash from poly_tx order by tx_index desc limit 10;

Is-Accept-Token checking of Starcoin account

Before relay Poly Tx.(to-Starcoin), realyer will check the target(Starcoin) account is-accept the token in cross-chain transfer Tx., if account not accept, save it in poly_tx_retry table temporary. The scheduled tasks will check it periodically, and commit it to Starcoin when account accept.

Check poly_tx_retry table:

select from_chain_id, tx_hash, starcoin_status, check_starcoin_count, check_starcoin_message, fee_status from poly_tx_retry;

Disable (Starcoin)to Poly relaying

Can use command flag to-poly-disabled(or env. variable TO_POLY_DISABLED) to do this:

./poly-starcoin-relayer --cliconfig ./config-testnet.json --to-poly-disabled

Disable (Poly)to Starcoin relaying

Can use command flag to-starcoin-disabled(or env. variable TO_STARCOIN_DISABLED) to do this:

./poly-starcoin-relayer --cliconfig ./config-testnet.json --to-starcoin-disabled

Re-handle Poly height

If relayer somehow missed hanlding a poly height, can use this to re-handle it:

./poly-starcoin-relayer --cliconfig ./config-testnet.json --re-handle-poly-height 24924223

Use BoltDB

Relayer use MySQL DB by default, can use BoltDB also, but only when (Poly)to Starcoin relaying is disabled:

./poly-starcoin-relayer --cliconfig ./config-testnet.json --to-starcoin-disabled --use-boltdb
