Summary of Changes

Hello @134130, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request undertakes a significant refactoring of the core task management services by deprecating and removing the MiseProjectService. Its functionalities, primarily related to resolving and caching Mise tasks and configuration files, have been re-architected and integrated into the MiseTaskResolver and MiseConfigFileResolver. This change not only improves the lifecycle management and cache invalidation mechanisms of these services but also simplifies the project's startup sequence and modernizes various API usages across the codebase, leading to a more robust and efficient system for handling Mise-related data.

Highlights

Service Replacement: The MiseProjectService has been entirely removed, with its responsibilities for task resolution and caching now distributed between MiseTaskResolver and MiseConfigFileResolver.
Enhanced Cache Management: Both MiseTaskResolver and MiseConfigFileResolver now implement the Disposable interface and manage their own cache invalidation by subscribing to MiseTomlFileVfsListener events, ensuring caches are cleared upon relevant file changes.
Streamlined Startup and API: The MiseStartupActivity has been simplified, no longer requiring explicit initialization of the removed service. Additionally, MiseTaskResolver introduces a more convenient getMiseTasks() method that defaults to the project's base directory, and smartReadAction is consistently used for safer read operations.
Codebase Modernization: The MiseTomlFileVfsListener has been refactored for better modularity and lifecycle management, and the Project.baseDirectory() utility function is no longer marked as deprecated, improving overall code clarity and maintainability.

Code Review

This pull request refactors the project by replacing MiseProjectService with MiseTaskResolver, which is a good move towards a more on-demand and reactive architecture. The changes are mostly consistent and improve the codebase by using newer platform APIs like smartReadAction.

However, I've found a critical issue in MiseTomlFileVfsListener where file change listeners are not being registered, which will break cache invalidation. I've also noted a potential regression due to the removal of a PsiTreeChangeListener. Additionally, a test has been disabled, which should be addressed. Please see my detailed comments.

    fun `test tasks`() {
+        // TODO: fix the test directory
+        return


This test is currently disabled with a return statement. It's good practice to either fix disabled tests as part of the same pull request or create a follow-up issue to track the work and link it in a comment. Leaving disabled tests in the codebase can lead to them being forgotten and bit-rotting.

Pull request overview

This PR refactors the codebase by replacing MiseProjectService with MiseTaskResolver, removing the need for explicit initialization and centralizing task resolution logic. The refactoring eliminates the service layer that managed task caching and refresh logic, instead moving to an on-demand task resolution model with per-directory caching.

Removed MiseProjectService entirely and migrated its task retrieval functionality to MiseTaskResolver
Updated all callers to use MiseTaskResolver.getMiseTasks() with runBlocking for synchronous access
Simplified VFS listener registration and event handling by making services disposable and self-registering

+            val tasks = runBlocking { project.service<MiseTaskResolver>().getMiseTasks(element.project.baseDirectory()) }


Using runBlocking in a reference provider can freeze the UI during resolve operations, causing editor lag and poor user experience. Consider using cached values or IntelliJ's async reference resolution mechanisms to avoid blocking the UI thread.

        return result
    }

+    override fun dispose() {}


The empty dispose method should either contain cleanup logic or be removed if not needed. If MiseTaskResolver truly has no cleanup to perform, consider documenting why the Disposable interface is implemented without cleanup logic, as this can be confusing for maintainers.

Suggested change

override fun dispose() {}

override fun dispose() {

// Clear cached tasks when the project/service is disposed.

cache.clear()

}

+                .map { MiseTaskGraphNode(MiseTaskGraphableTaskWrapper(it), provider) }
+        }


Using runBlocking in field initialization can block the thread during service construction, potentially causing startup delays or deadlocks. Consider lazy initialization or moving this computation to a suspend function that's called when needed.

+                val tasks = runBlocking { project.service<MiseTaskResolver>().getMiseTasks(project.baseDirectory()) }


Using runBlocking in field initialization can block the thread during service construction. This is especially problematic in an apply block where exceptions might not be properly handled. Consider refactoring to use lazy initialization or a suspend function.

+        // TODO: fix the test directory
+        return


The comment "TODO: fix the test directory" along with the early return indicates this test is disabled. Either fix the test to work properly with the new MiseTaskResolver implementation or remove it if it's no longer relevant.

Suggested change

// TODO: fix the test directory

return

        sequence {
-            val tasks = project.service<MiseProjectService>().getTasks()
+            @Suppress("RunBlockingInSuspendFunction")


The Suppress annotation "RunBlockingInSuspendFunction" is misleading here. The loadNodes() function is not a suspend function - it returns a sequence. Using runBlocking in a regular function doesn't warrant this suppression. Consider either removing the suppression or refactoring this code to properly use coroutines.

Suggested change

@Suppress("RunBlockingInSuspendFunction")

Using runBlocking in a completion provider can freeze the UI thread while waiting for async operations to complete. This blocks the editor and creates a poor user experience. Consider using a cached value, returning preliminary results, or using IntelliJ's async completion APIs to avoid blocking.

Using runBlocking in a documentation provider can freeze the UI when hovering over elements to view documentation. This creates a poor user experience with noticeable lag. Consider using cached values or returning placeholder documentation while loading asynchronously.
