Overlay: check query packs for compatibility by cklin · Pull Request #2993 · github/codeql-action · GitHub

This PR updates the init action to prevent overlay analysis (or overlay-base database construction) when one of the query packs involved does not support overlay analysis with the installed CodeQL CLI.

@alexet Please review the aspects concerning interaction with the CodeQL bundle

It doesn't feel to me that resolve packs is quite the right command (although it looks like it will work).It feels like we should run resolve queries with --format startingpacks to find the query packs we care about, and then just use those.

But I am also not fully sure of all the subtleties of either choice.

Thanks for the suggestion!

When I first looked into the problem, I considered this approach but was unable to get it to work. While codeql resolve queries with --format startingpacks can map queries to their containing query packs, there does not seem to be a way to get the list of queries that would be used in the analysis and feed that into codeql resolve queries. I could see that codeql database init already computes that information (though a deep-plumbing subcommand) for internal use, but no easy way to obtain that information from outside the CodeQL CLI. Re-interpreting the Code Scanning config file in the action seems like a lot of work for relatively little gain.

Prompted by your suggestion, I looked again. This time I noticed that codeql database init actually generates config-queries.qls suite file with the list of queries, so all I need to do is to feed that suite file into codeql resolve queries, and I can get the list of query packs to check for overlay compatibility.

(There is the slight complication that codeql resolve queries --format startingpacks would also return query packs that have not been compiled. I will have to make the action ignore those query packs when checking for overlay compatibility.)

I updated the PR to use this approach to identify the query packs to check for overlay compatibility. Related changes:

I removed the commit that adds resolvePacks() to the CodeQL interface
Instead, there is now a commit to add resolveQueriesStartingPacks()
To avoid confusion, I removed the unused resolveQueries() from CodeQL
While I am at it, I also removed the unused packDownload() from CodeQL

The other commits remain the same as before. PTAL.

The latest force push updated CODEQL_OVERLAY_MINIMUM_VERSION to 2.22.3 at Alex's request.

As always, thanks for taking on this work! I have added a few suggestions, questions, and points for discussion.

Not specific to this PR: I see that we follow the same JSON.parse(output) as type pattern throughout the implementation here, but that doesn't actually give us any guarantees that the result of JSON.parse is compatible with the type here. This may effectively delay an error until a later point. Where possible, we should probably check that the result actually what we expect (and not just valid JSON) as done in e.g. #2956.

I don't think this has to be addressed here, but we might want to look into improving this throughout in the future.

Acknowledged. I will leave it to you to decide if and when you want to perform that overall cleanup.

I agree with Copilot here - it would be good to have typings for (at least) the parts of the format that are used here.

This might also make the tests a little nicer since you can then have test objects of this type that you can serialise, rather than hard-coded strings.

Agreed with Copilot. It would be good to distinguish errors while reading/parsing JSON from other errors.

Just noting this for future reference: it doesn't look like dbLocation is used by generateRegistries, so moving this seems fine.

Furthermore, codeql database init generally expects the database path to be non-existent and reports an error when the database path already exists. (There are some exceptions, such as when initializing an overlay database.) So I would be very surprised if generateRegistries() writes anything into dbLocation.

Pull Request Overview

This PR adds query pack compatibility checking for overlay analysis in the CodeQL Action. The main purpose is to ensure that when overlay analysis is enabled, all query packs involved are compatible with the installed CodeQL CLI's overlay analysis support before proceeding.

Introduces a new checkPacksForOverlayCompatibility function that validates query pack overlay compatibility
Refactors the runInit function into runDatabaseInitCluster and updates the overlay compatibility checking workflow
Updates the minimum CodeQL overlay version requirement from "2.20.5" to "2.22.3"

src/init.ts:79

[nitpick] The parameter order in runDatabaseInitCluster is inconsistent with the original runInit function. Consider maintaining the same parameter order (codeql, config, sourceRoot, processName, then additional parameters) for better consistency and easier migration.

export async function runDatabaseInitCluster(
  databaseInitEnvironment: Record<string, string | undefined>,
  codeql: CodeQL,
  config: configUtils.Config,
  sourceRoot: string,
  processName: string | undefined,
  qlconfigFile: string | undefined,
  logger: Logger,
): Promise<void> {

src/init.ts:138

[nitpick] The interface QlPack is too generic and incomplete for representing a qlpack.yml file structure. Consider renaming it to QlPackMetadata or QlPackYaml to be more specific about its purpose.

interface QlPack {
  buildMetadata?: string;
}

I responded to some of the comments, and will follow up on the remaining ones tomorrow.

@mbg Friendly ping

Thanks for addressing my feedback from the last review, and sorry it took longer than I'd like to re-review.

This continues to look good, thank you! I've followed up to a few of your responses and added a couple of suggestions for potential improvements on test coverage.

I am generally happy with this and there isn't anything that's really blocking. Have a look over the comments and see if you want to change anything in light of them. I will be happy to approve this after you've had a look.

On second thought, I think it's probably fine. You're right that whatever errors come out of here are probably distinguishable based on the result of util.getErrorMessage(e) in the existing catch block.

The PR removes resolveQueries and adds resolveQueriesStartingPacks. For the corresponding tests, the ones for resolveQueries are removed, but none are added for resolveQueriesStartingPacks. Do you think it would make sense to add some?

I did not remove any resolveQueries tests. What I removed was unnecessary resolveQueries and packDownload stubs in config loading tests. Those tests are still working the same way they used to: the removed resolveQueries and packDownload stubs has no effect on the tests because the tested code does not call either of those functions.

resolveQueriesStartingPacks is just a wrapper that calls the corresponding CodeQL CLI subcommand, and I don't think tests for that function would add much value.

Do you think it's worth adding a test that exercises this logic? I don't see anything wrong with things as they are, but it might be worthwhile to have to check that we don't break this sequence, especially since an error in cleanupDatabaseClusterDirectory would be fatal. I don't feel strongly about it.

I added a new PR check to exercise this re-initialization logic.

This commit inlines runInit(), so that it is easier to repeat the runDatabaseInitCluster() call when needed.

@mbg Thanks for your comments. I think I responded to them all.

There has been a few force pushes to the PR branch, both to resolve merge conflicts and to iterate on the new database re-init PR check. The following link contains all the relevant changes since your last review:

Edit: I updated the comparison link because I added a commit to support the codeql-pack.yml pack file name.

Thanks for making those final changes!
