Summary of changes

  • Add Microsoft.Azure.Functions.Worker.Extensions.Http.AspNetCore to the embedded ThirdPartyModules name list.

Reason for change

  • AssemblyFilter.ShouldSkipAssembly (used by SpanCodeOrigin.SetCodeOriginForEntrySpan) consults ThirdPartyModules.Contains for case-sensitive exact-match membership against the assembly's simple name.
  • That assembly hosts Microsoft.AspNetCore.Http.FunctionsHttpContextExtensions, which is what ASP.NET Core endpoint resolution surfaces for Azure Functions Isolated HTTP triggers. Because the assembly was missing from the list, Code Origin attributes the entry frame to FunctionsHttpContextExtensions.InvokeFunctionAsync - a framework method - instead of skipping the assembly entirely.

Implementation details

  • Single-line insertion, placed in the correct position within the Microsoft.Azure.Functions.Worker.* family.

7157e47 
…third-party

Add Microsoft.Azure.Functions.Worker.Extensions.Http.AspNetCore to the
ThirdPartyModules name list so AssemblyFilter.ShouldSkipAssembly returns
true for it. Without this, Code Origin attributes Azure Functions Isolated
HTTP entry spans to FunctionsHttpContextExtensions.InvokeFunctionAsync
instead of skipping the framework assembly.

Benchmarks

Benchmark execution time: 2026-05-13 14:27:36

Comparing candidate commit 7157e47 in PR branch dudik/co/azfunc-thirdparty with baseline commit 5a188d7 in branch master.

Some scenarios are present only in baseline or only in candidate runs. If you didn't create or remove some scenarios in your branch, this maybe a sign of crashed benchmarks 💥💥💥
Check Gitlab CI job log to find if any benchmark has crashed.

Found 1 performance improvements and 2 performance regressions! Performance is the same for 48 metrics, 21 unstable metrics, 87 known flaky benchmarks, 39 flaky benchmarks without significant changes.

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 ----------------------------------'
