test: Convert non-wallet tests to use our python MiniWallet #20078

issue maflcko openend this issue on October 4, 2020
  1. maflcko commented at 2:41 pm on October 4, 2020: member

    It is possible to compile Bitcoin Core without the wallet. Though, many tests require the Bitcoin Core wallet to create and sign transactions. Ideally, every non-wallet test (for example consensus tests) are run even with the Bitcoin Core wallet disabled. This ensures that users running without the wallet can test their Bitcoin Core with the functional test suite.

    Thus, tests that use the Bitcoin Core wallet should be rewritten to use the python MiniWallet.

    This is an open-ended issue. You can find candidate tests via git grep 'self.skip_if_no_wallet()'. Exclude the tests that start with wallet_, as those are tests that are meant to test the Bitcoin Core wallet.

    Refer to #19922 and #19800 as examples on how to approach this issue.

    Edit: See also #20078 (comment)

    Useful skills:

    • Familiarity with the RPC interface
    • Familiarity with our functional test suite
    • Good python3 skills

    Hey, I can give this issue a shot.

    Sure. No need to ask on this one, as it is open ended. There should be enough tests for everyone to convert

    hi there, does this issue still require work to be done on it?
  13. michaelfolkson commented at 6:43 pm on December 30, 2020: contributor

    @stackman27: As far as I can tell there are around 40 tests from git grep 'self.skip_if_no_wallet()' excluding tests starting with wallet_ (From Marco’s initial description)

    If you look at the above notifications it appears 4 test updates have been merged and 1 test update is open. Marco initially fixed two (p2p_feefilter.py, rpc_txoutproof.py) So there are lots of tests to work on.

    Please link to this issue if you open a PR as it will make it easier to monitor which ones people are working on.

    How would I go about creating and sending tx using miniwallet when the utxo generated doesnot have a key value in the output? Should I just manually append it or is there anything I’m missing? I found this issue while working on mempool_limit.py while creating utxo using create_confirmed_utxos
  15. michaelfolkson commented at 12:47 pm on December 31, 2020: contributor

    @stackman27: The Miniwallet class defines self._address which is a ADDRESS_BCRT1_P2WSH_OP_TRUE from address.py. This OP_TRUE address can be spent with a witness stack of just OP_TRUE so it doesn’t need any keys.

    In mempool_limit.py that should be fine for create_confirmed_utxos. I’m trying to work out if that is a challenge with create_lots_of_big_transactions later… I don’t think it is if I understand what is going on with splicing in "txouts" to each raw transaction

    For more info on OP_TRUE addresses (P2SH rather than P2WSH but may be useful): https://bitcoin.stackexchange.com/questions/72773/how-to-create-a-p2sh-transaction-with-a-scriptsig-of-op-true

    Did you answer your question @stackman27? I think you deleted your latest post asking about value in wallet.py versus amount in mempool_limit.py. I think you can use value for amount unless I’m missing something.

    I think so. I just generated utxos using miniwallet.generate rather than create_confirmed_utxos

  18. stackman27 commented at 5:37 am on January 4, 2021: contributor
    @michaelfolkson i’m sorry to bug you so much. But how would i setup create_lots_of_big_transactions without modifying the send_self_transfer? Here’s what my setup looks like (https://ibb.co/gT8ctjW) but it’s not returning the correct mempoolminfee. Any hints?

    I’ll have a go at mempool_reorg.py! Just putting it out there as it’ll be my first commit so I’m not sure how long it’ll take.
  22. stackman27 commented at 8:32 pm on January 31, 2021: contributor
    Hi @MarcoFalke is there a way to get information about a tx in miniwallet I tried doing node.gettransaction(txid) but got Invalid or non-wallet transaction id (-5) error?
  23. maflcko commented at 6:36 am on February 1, 2021: member
    miniwallet returns the transaction details when you create a transaction. If you need mempool info about the tx, you can use a mempool rpc. Note that the miniwallet itself doesn’t track the mempool/chain as of now.
  24. stackman27 commented at 4:02 pm on February 8, 2021: contributor

    hi @MarcoFalke, I was refactoring mempool_accept and felt the need to just sign an existing tx also in some parts of the code I only had to create a raw tx. So, I was wondering if it’d be good idea to break down send_self_transfer into create, sign & spend rather than just having to pass boolean send_tx or create_tx into the functional parameter?

    Also, how about the idea of accepting multiple inputs to spend like what’s being done here, I believe currently we can only spend one input utxo, but I think allowing multiple inputs to spend will prevent repetitions

  25. maflcko commented at 4:20 pm on February 8, 2021: member
    Splitting creation and signing doesn’t make too much sense, I think, because signing is just pushing OP_TRUE, which would complicate the interface to having to do manually or in a second step. Splitting up send_tx could make sense if it makes the interface clearer.

    Haven’t looked through to see which of the tests still to be updated to use MiniWallet would benefit from having access to P2PK outputs but #21945 is introducing them.

    Look at other tests that could benefit from P2PK (e.g. feature_cltv.py?)

    Something also to consider for future Miniwallet PRs (as discussed in #24635) is if your test is run twice in the test runner ensure that it is only run once (could be done in same PR) once the dependence on the Core wallet is removed. I’ll try to monitor these and do this if people forget.

    I would remove example_test.py from the list, I don’t think it should really be “fixed”, it’s only showing how to skip a test if the module is missing :)

    Also, I’m still working on raw_transaction.py (see #20078 (comment)), I’m almost there :)

    Thanks @shommel for the list! Didn’t realize how much progress had been made, not many left now.

    I was planning to play around with Taproot in Python at some point so I’ll take feature_taproot.py (somewhat surprised it is still there). If someone wants to take it off me feel free though.

    From the description of the issue

    This is an open-ended issue. You can find candidate tests via git grep ‘self.skip_if_no_wallet()’

    I understand why those tests are the obvious candidates for MiniWallet usage, but are those the only tests that could benefit from MiniWallet usage?

    During the process of converting tests to use the MiniWallet, a number of practical methods have been created thus enabling more readable tests by using the MiniWallet class. I am trying to understand if the usage of the MiniWallet to simplify tests that can already run with the Bitcoin Core wallet disabled (e.g. #25379) is something that could be considered beneficial.

    Nice. Pull requests welcome, however I am going to close this issue for now. The remaining tests can not be trivially converted without also extending MiniWallet (I think), so it might be better to open specific threads/issues for each test.
