Bitcoind for onchain #317

WIP: Starting PR for #272

…(TODO: estimateSmartFee is not working yet)

@jotapea please pay attention to your commit messages we are trying to follow this guide for standard commit messages (first line 50 characters).

And the check-code task is failing on GitHub actions. Perhaps you could setup your editor to run prettier on save to avoid this.

jotapea · 2021-07-09T05:28:49Z

@bodymindarts Will do, thanks for the feedback!

This reverts commit e2a4b73.

- Encapsulates variation between onchain clients - LndOnChainClient class implements the original lnd-onchain calls - This class may be temporary, but it is currently useful to switch between lnd and bitcoind in one line

- TODO: getEstimatedFee method is not working yet - The tests start to fail...

if it is a timeout fail is because waitUntilBlockHeight. Basically in lnd the "pruning channel graph" is taking more than the timeout in jest.

you can check docker logs to verify that this is the case

increase timeout in jest setup https://github.com/GaloyMoney/galoy/blob/main/test/jest.setup.js

also you can check if adding routing.assumechanvalid=true to lnd.conf can help. I have not fully tested but you can give it a try

Thanks for this, modifying the timeout has allowed me to retry the tests when these show the following error:

FAIL test/integration/02a-fund-bitcoind.spec.ts (36.247 s) ✓ funds bitcoind wallet (3697 ms) ✕ funds outside lnd node (30268 ms) ● funds outside lnd node thrown: "Exceeded timeout of 30000 ms for a test. Use jest.setTimeout(newTimeout) to increase the timeout value, if this is a long-running test." 66 | }) 67 | > 68 | it("funds outside lnd node", async () => {

But this seems to be "unrelated?" to the the main failure that the tests are showing, which is that the balance sheet is no longer balanced.

@jotapea FYI tests are NOT idempotent so you always have to run make reset-deps between runs.

Yes I'm running them with 'make integration' the first time and then 'make reset-integration' the rest of the times.

is a highly coupled class with getActiveOnchainLnd. Maybe is better pass the lnd client as parametter (the same for BitcoindClient)

The main purpose of the classes at the moment is for ease of development purposes. After the bitcoind client works as a replacement to the lnd client, then we could reconsider the purpose and structure of these classes.

but you have only one instance (line 68) and in the same file

is this still relevant @dolcalmi ?

@dolcalmi Notice that this is the same call that is now in line 90 (this.client = getActiveOnchainLnd().lnd), so it should work just like it used to.

The equivalent test for the default wallet passes

All tests still pass after I renamed the default wallet from "" (unnamed) to "default". But adding the test to create a second wallet ("hot") fails just after creation. Made a comment of this failure: https://github.com/GaloyMoney/galoy/pull/317/files#diff-67ab19f16c472b30989f27f5755650158189756bbf68874767a0ff7196c50a05

@nicolasburtey @krtk6160 how should I proceed? Why is the "default" wallet bypassed for the balance sheet tests?

not sure if you can change the default wallet. The current production environment use "" as default wallet

@jotapea I will need to dig deeper to understand why it's failing but some feedback on top of my head that could be relevant:

since bitcoind 0.20 (or 0.21?) the behavior of bitcoind changed in regards to defauilt wallet and now no default wallet is being created automatically. the code has been udpated to accomodate this but IIRC it was a bit hacky

we currently only use the bitcoin wallet in production is for the multisig that is created by specter. the other use of bitcoind is currently only for the test (maybe we should have 2 bitcoind instance to make this more explicit... one that is for the wallet we use, and another bitcoind that represents the "outside world")

the test instantiated a separate wallet just because we need to have some BTC coming from somewhere. lnd is not getting the BTC directly from the coinbase rewards because the funds are not available immediately and I had issues with that: lnd typically doesn't expect to be the recipient of a coinbase rewards that has timelock restriction. (need to wait X blocks before the coinbase rewards is spendable)

@nicolasburtey Renamed test from 02a-fund-bitcoind to 02a-fund-outside

it("funds default/outside bitcoind wallet", async () => {} it("funds outside lnd node", async () => {}

And using it in OnChain:BitcoindClient

- The funding tests now pass - But the checkIsBalanced starts failing after crediting lnd tests (TODO)

This reverts commit 0d34550.

This test is being commented out (just for now). Many of SpecterWallet methods consider the outside (default) wallet being bypassed in tests. In addition to also considering lnd as the onchain wallet.

This is what I plan to continue working on... but @nicolasburtey let me know if this is the best path or if I should focus on something else.

But the rest of the tests don't

This reverts commit 3137c35.

Instead of just replacing the default client with the outside client, it seems appropriate to still keep a default client around for non- wallet bitcoin-node specific functionality

jotapea · 2021-07-19T18:13:04Z

To replicate the architecture of listening for lnd's chain_transaction and block events with bitcoind, ZeroMQ needs to be setup #346.

jotapea · 2021-07-20T16:41:44Z

Dividing this into multiple tasks so that we can review and merge smaller branches, these being preparation for bitcoind fully replacing lnd for onchain transactions:

First: Replace default bitcoind wallet with multiple purpose specific wallets
Listen to bitcoind with ZeroMQ
...
Finally this one: Bitcoind for onchain
