Summary | 0004883: either remove transaction_id from exchange or use it for multiple payments for the same proposal | ||||
Description | Before the contract->proposal rename, the exchange got the transaction_id from the merchant, but never did anything with it. After the rename, the merchant has a order_id instead of a transaction_id, but the transaction_id might still be used to disambiguate multiple payments from the same proposal between merchant BACKEND and exchange. The merchant-frontend or wallet should never see it. However, it is not clear whether the mechant-backend and exchange really need the transaction_id, or the hash of the (normalized / with sorted coins) deposit permission suffices. EDIT: we need it, since coins are deposited with multiple independent API calls, and we need to correlate those. | ||||

Christian, you're more familiar with the exchange but currently out of office, can you give your opinion on this so I can work on it? |
|
Ohh, what I said above is wrong actually. We submit coins one-by-one, so we can't use the deposit permission hash. We still need the transaction_id! But it's only visible between merchant-backend and exchange. |
|
FIXME: the functions: 1) TALER_EXCHANGE_deposit 2) TALER_EXCHANGE_track_transaction in the exchange's lib needs to 1) rename the transaction_id to order_id (Not sure about that: from the exchage's perspective, they might be _transactions_) 2) type it as "const char *" (as now it's uint64_t) 3) remove the use of h_contract. |
|
Not quite, the exchange never actually cares about the order_id. We must keep transaction_id as it's important for the merchant taxation when having multiple payments per proposal. |

Fixed in: https://git.taler.net/exchange.git/commit/?id=8c820b6916 https://git.taler.net/exchange.git/commit/?id=4363911618 Note that the transaction_id is still there, but on the wallet/merchant's side, it won't be part of the contract anymore. It's only used to group deposits together on the merchant side for tax and wire transfer reasons. |
