GitHub: use bitcoind v26.0 for CI by guggero · Pull Request #8273 · lightningnetwork/lnd

guggero · 2023-12-12T19:58:58Z

Depends on #8555.

Change Description

See if things break in the CI if we update to bitcoind v26.0.

guggero · 2023-12-18T17:41:54Z

Okay, so the failed unit tests were due to a number of reasons:

bitcoind v26.0 doesn't have support for Unix Sockets (ipc://) in ZMQ anymore. Broken by Validate port-options bitcoin/bitcoin#22087, will be fixed by ZMQ: Support UNIX domain sockets bitcoin/bitcoin#27679
We had frequent TCP listening port collisions, at least when running the tests locally
We didn't clean up temporary directories for bitcoind sometimes

I added a couple of commits to address these issues.

yyforyongyu

Thanks for the cleanup! No major comments, just need to merge the dependent PR first. And the unit tests need to be fixed.

LGTM 🎨

Unit tests still failing. One of the itest failures has uncleaned shutdown that still occupying a port, werid

 unable to create server: listen tcp 127.0.0.1:6563: bind: address already in use

guggero · 2023-12-22T07:13:11Z

Yeah, it seems like I have to do some more digging into failures.

yyforyongyu · 2024-01-16T11:43:58Z

I think we should use one place to manage the version, to avoid mistakes such as 994a142

Maybe this is a dumb question but why isn't this number 26?

This is just the fallback version in case no environment variable is set. We set the version we actually want here: https://github.com/lightningnetwork/lnd/blob/ff3e8da1756572b0dd979a39b139a969498772dd/.github/workflows/main.yml#L24

But I guess we shouldn't do that to avoid confusion...

Tips

Chat

There are 3 ways to chat with CodeRabbit:

Review comments: Directly reply to a review comment made by CodeRabbit. Example:
- I pushed a fix in commit <commit_id>.
- Generate unit-tests for this file.
- Open a follow-up GitHub issue for this discussion.
Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
- @coderabbitai generate unit tests for this file.
- @coderabbitai modularize this function.
PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
- @coderabbitai generate interesting stats about this repository and render them as a table.
- @coderabbitai show all the console.log statements in this repository.
- @coderabbitai read src/utils.ts and generate unit tests.
- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

I pulled this down and tested it and it looks like everything passes except a wtclient test (possibly a flake?). It doesn't seem related to this as best I can tell. I think that test will pass if you rebase this.

@Roasbeef can you see the logs of the failed Travis build?
I only get this error message (not sure if we need to re-auth the app somehow?):

To make it less confusing what version of bitcoind is actually installed, we now require the version to be specified as a command line argument. Because we tag the version in the docker image tag as bitcoin-core:XX but the binary internally is located under /opt/bitcoin-XX.Y/, we manually set Y to 0.

With this commit we create a new function that returns system wide unique ports by using a single file to keep track of previously used ports. We'll want to use this everywhere whenever we need to listen on a new, random port during unit or integration tests. Because we now have a unique source, we don't need to apply the port offset that was used for the different tranches of parallel running integration tests before.

Make sure we wait for the initial connection long enough.

This commit fixes a number of issues with our temporary bitcoind nodes that we spin up for unit tests: - We didn't remove the node's temporary data dir after tests finished. - We used random ports which lead to unwanted port collisions. - We used ipc:// unix sockets for ZMQ which currently isn't supported in bitcoind v26.0 due to a regression. Since we can reliably create new non-colliding ports now, we should use TCP for ZMQ anyway.

With the chainntnfs.NewMiner now being optimized for not creating nodes with colliding ports, we use it in all unit tests that spin up temporary miners.

To avoid circular dependency issues between packages, we move the unit test backend creation function to a new package in the lntest parent package.

Since we fixed a number of issues in chainntnfs.NewBitcoindBackend that makes it compatible with bitcoind v26.0, we now want to use that function in all our unit tests.

To make it easy to add "-test.v" and "-test.count=1" to the unit tests, we add two new make flags.

This is a commit to attempt to fix Travis which runs on ARM64.

Because we pass in the same config into multiple notifiers, we sometimes get a data race in the unit tests. By creating a copy of the config we avoid that.

guggero · 2024-03-18T20:32:47Z

Okay, this is as green as it will probably ever get. There are still a couple of (pre-existing!) flakes in there. But I vote to get this merged since they very likely don't have anything to do with bitcoind.

yyforyongyu

LGTM, thanks for the fix🙏

yyforyongyu · 2024-03-19T19:36:57Z

btw can we update our merge rules to exclude the build from macOS?

It's currently not included in the list of required tests. So merges shouldn't be blocked on it (same for Windows).

pinheadmz · 2024-04-18T13:47:50Z

FWIW bitcoin/bitcoin#27679 is updated, has two ACKs already, and a review from an LND dev would be helpful to get a merge ;-)
