[electrum] use TxInput (almost) everywhere in transaction.py
ClosedPublic

Authored by PiRK on Sep 12 2023, 15:13.

Details

Summary

This makes the Transaction class use TxInput everywhere internally, except for a few remaining methods that work with fetched_inputs which still need to be converted.

Input setters and their callsites are also converted:

  • Transaction.add_inputs
  • Transaction.set_inputs
  • Transaction.update_input
  • Transaction.from_io

As of this diff, sweep uses TxInput objects to estimate the tx size, so the test needs to be adjusted to have properly formed scriptsigs that can be parsed by TxInput.

Depends on D14510

Test Plan

python test_runner.py

Send and receive transaction with the application.
Send transactions with hardware wallet.

rebase, minor improvements (assertions for type of inputs, more uses of inputs() converted in Transaction) and fixes (hardware wallets)

PiRK edited the summary of this revision. (Show Details)

rebase and:

  • remove unused sign_schnorr argument in sweep_preparations (I think at some point I passed this to TxInput.from_coin_dict)
  • remove a debugging comment in test_transaction
  • document Transaction.inputs() (mention that it is deprecated)

Cleaning this is on my TODO list, but I need to dive into the code related to fetched_inputs first.

It seems to me the prev_tx change should be its own diff

I don't think it really matters but is there any benefit in using a tuple instead of a list ? It's ro anyway

rebase after doing the prev_tx change in another diff

PiRK planned changes to this revision.Sep 20 2023, 13:21

i think there was a rebase incident

fix typo (i'm pretty sure I fixed this before, but maybe it got lost in an aborted rebase)
Rerun all the interactive tests to be sure.
