Remove cleanup-on-shutdown for temporary files #8746

jbachorik · 2025-04-28T17:15:48Z

What Does This Do

It removes the 'cleanup-on-shutdown' functionality from the TempLocationManager

Motivation

This cleanup can race against profiling-snapshot-on-shutdown and prevent those profiling snapshots to be sucessfully generated.
All of this for a small benefit of not having a few MiB of temp files for slightly longer time - the cooperative cleanup, when any other java process with the profiler starts up, will take care of those file anyway.

Pull Request Overview

This PR removes the shutdown hook–based temporary file cleanup from the TempLocationManager to avoid race conditions with profiling snapshot generation. Key changes include:

Removing the shutdown hook and self-cleanup parameter from TempLocationManager.
Updating tests to call cleanup() without the self-cleanup flag.
Introducing a new ignore(Path) method to allow specific temporary paths to be exempted from cleanup.

Reviewed Changes

Copilot reviewed 3 out of 3 changed files in this pull request and generated no comments.

File	Description
dd-java-agent/agent-profiling/profiling-controller/src/test/java/com/datadog/profiling/controller/TempLocationManagerTest.java	Updated cleanup method calls in tests to remove selfCleanup parameter.
dd-java-agent/agent-profiling/profiling-controller/src/main/java/com/datadog/profiling/controller/TempLocationManager.java	Removed shutdown hook logic and associated self-cleanup code; modified the CleanupHook interface and CleanupVisitor accordingly; added an ignore(Path) method.
dd-java-agent/agent-profiling/profiling-controller-openjdk/src/main/java/com/datadog/profiling/controller/openjdk/OpenJdkController.java	Updated to retrieve the TempLocationManager instance before resolving the JFR repository path.

Comments suppressed due to low confidence (3)

dd-java-agent/agent-profiling/profiling-controller/src/main/java/com/datadog/profiling/controller/TempLocationManager.java:299

The removal of the shutdown hook is in line with the PR purpose; please ensure that the cooperative cleanup mechanism adequately handles leftover temporary files in all runtime scenarios.

Runtime.getRuntime().addShutdownHook(selfCleanup);

dd-java-agent/agent-profiling/profiling-controller/src/main/java/com/datadog/profiling/controller/TempLocationManager.java:365

Consider adding unit tests and JavaDoc for the new ignore(Path path) method to ensure its behavior is well validated.

public void ignore(Path path) {

dd-java-agent/agent-profiling/profiling-controller/src/main/java/com/datadog/profiling/controller/TempLocationManager.java:105

[nitpick] The removal of the self-cleanup check in preVisitDirectory affects the exclusion of the JFR repository. Please confirm this change is intentional and update the inline comments to clarify the intended behavior.
