chore(heap-profiling): remove free USDT when live-heap is not available [PROF-15190]

[scottgerring]

What does this PR do?

When the user does not opt into the live-heap feature, we should not emit the free USDT. This lets an attached profiler know that live heap is not available, making its life easier (e.g., it knows not to track sampled allocations).

Pull request overview

Adjusts the heap-sampler USDT probe emission so external profilers can detect whether “live-heap” correlation is supported by checking for the presence/absence of the ddheap:free USDT note.

Changes:

• Gate ddheap:free USDT emission behind DD_HEAP_LIVE_TRACKING in dd_probe_free.
• Stop calling dd_probe_free on the sampled-free slow path when live-heap tracking is disabled.
• Document that the dd_probe_free symbol always exists, but the USDT note is only present with live-heap tracking enabled.

libdd-profiling-heap-sampler/src/probes.c	Conditionally emits the ddheap:free USDT based on DD_HEAP_LIVE_TRACKING.
libdd-profiling-heap-sampler/src/allocation_freed.c	Skips firing the free probe when live-heap tracking is disabled.
libdd-profiling-heap-sampler/include/datadog/heap/probes.h	Clarifies probe behavior and how external profilers can infer live-heap support.

Benchmarks

Comparison

Benchmark execution time: 2026-07-13 14:07:14

Comparing candidate commit 2989b1b in PR branch sgg/no-live-heap-no-probe with baseline commit 20c267e in branch main.

Found 1 performance improvements and 0 performance regressions! Performance is the same for 39 metrics, 0 unstable metrics.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

• 🟩 = significantly better candidate vs. baseline
• 🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'
