test(profiling): unflake some tests by KowalskiThomas · Pull Request #15797 · DataDog/dd-trace-py

KowalskiThomas · 2025-12-29T07:28:00Z

Description

This makes some tests less flaky. Previously, we would sometimes parse an empty Profile (0 samples in it) and make the test fail. The fix is to, when this happens, ignore the failure and parse/use the previous Profile instead (which we expect to ALWAYS be non-empty).

chore(profiling): improve typing #15796

This makes some tests less flaky.

Can you please expand why?

Also, great variable naming, I had to look it up: penultimate: last but one in a series of things; second last. Unsure why it helps the test tho, lol.

The backport to 4.0 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-4.0 4.0
# Navigate to the new working tree
cd .worktrees/backport-4.0
# Create a new branch
git switch --create backport-15797-to-4.0
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 4e2e136b1a9e73ec2865978d10ba942d70596af5
# Push it to GitHub
git push --set-upstream origin backport-15797-to-4.0
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-4.0

Then, create a pull request where the base branch is 4.0 and the compare/head branch is backport-15797-to-4.0.
