gh-150258: Show relative percentage on Tachyon flamegraph by edvilme · Pull Request #150266 · python/cpython

edvilme · 2026-05-22T18:37:18Z

When running profiling, users rarely care about the global percentage of the runtime. Often, they want to select a function and measure child percentages relative to that.

This PR updates the flamegraph tooltips to show both "Percentage" and "Relative Percentage" when the user clicks a specific function.

Fixes #150258

Visualization

With no functions selected

With a function selected

Remarks

"Relative percentage" is only shown for the children of the selected node (<100%)

Issue: Split "Percentage" in tachyon flamegraph tooltip UI to "Percentage of Root" and "Percentage of Selected" #150258

Note: switching to '6f993631501eef77ab4bad6a4f9b5ea1f6351c89'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false
