test(profiling): make `memalloc` test less flaky #15769

KowalskiThomas · 2025-12-23T11:56:14Z

Description

https://datadoghq.atlassian.net/browse/PROF-13361

This makes the memalloc test less flaky by reducing the sampling interval. Currently, memalloc is our top flaky test.

The fix is:

Making heap_sample_size lower to maximise the number of Samples we take (heap_sample_size really should be heap_sample_interval, since that's literally what it's named internally in the Collector, but that's an another-day-problem)
More importantly, adding an assert_samples parameter to snapshot_and_parse_pprof to allow the caller not to do it. The reason is that we call snapshot_and_parse_pprof once just to reset the Sampler's state, so it's very possible that we didn't have Samples in the state at that moment (and it's completely OK if it happens). We only want to assert we have Samples when we want to... look at the Samples.

The backport to 3.19 failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-3.19 3.19
# Navigate to the new working tree
cd .worktrees/backport-3.19
# Create a new branch
git switch --create backport-15769-to-3.19
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 ad2137d426a19345f7612b2bf23a1c6046cae67a
# Push it to GitHub
git push --set-upstream origin backport-15769-to-3.19
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-3.19

Then, create a pull request where the base branch is 3.19 and the compare/head branch is backport-15769-to-3.19.

(cherry picked from commit ad2137d)

Backport ad2137d from #15769 to 4.1. ## Description This makes the `memalloc` test less flaky by reducing the sampling interval. Currently, `memalloc` is our top flaky test. <img width="1198" height="587" alt="image" src="https://github.com/user-attachments/assets/a29a5d58-e1a4-4da3-aa74-101387aeed2b" /> The fix is: - Making `heap_sample_size` lower to maximise the number of Samples we take (`heap_sample_size` really should be `heap_sample_interval`, since that's literally what it's named internally in the Collector, but that's an another-day-problem) - More importantly, adding an `assert_samples` parameter to `snapshot_and_parse_pprof` to allow the caller _not_ to do it. The reason is that we call `snapshot_and_parse_pprof` once just to reset the Sampler's state, so it's very possible that we didn't have Samples in the state at that moment (and it's completely OK if it happens). We only want to assert we have Samples when we want to... look at the Samples.
