Summary of changes

  • Add helper for automatically escaping string for inclusion in JSON
  • Update serverless injection to use the new helper
  • Refactor serverless usages of StringBuilder to avoid allocation

Reason for change

The serverless context injection has to modify JSON to add additional headers. It's currently doing that using a StringBuilder approach, but it's not currently accounting for any potential characters in the injected payloads that might need escaping. This is rare and unlikely, but theoretically possible.

Additionally, there's some inefficiencies in how the StringBuilder is used in some cases, which is doing more allocation than necessary (e.g. using multiple StringBuilders, using interpolation, using AppendFormat)

Implementation details

  • Created a new JsonHelper.WriteEscapedJavaScriptString() based on the vendored Newtonsoft.JSon version
    • The vendored version is more generalised than we need, and potentially allocates char[], which the new version avoids.
    • The simple iteration of the input string is generally sub optimal, but these are generally going to be small strings, so it's likely as good as anything, given no SearchValues availability
  • Updated the ContextPropagation implementations to use it
  • Fix the ContextPropagation implementation usages of StringBuilder

Test coverage

  • Added unit tests for the helper + behaviour of context propagation
  • Covered by existing integration tests

Benchmarks

Benchmark execution time: 2026-05-20 10:40:25

Comparing candidate commit f35a67b in PR branch andrew/serverless-escape-content with baseline commit 05f3138 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 3 performance improvements and 4 performance regressions! Performance is the same for 49 metrics, 16 unstable metrics, 84 known flaky benchmarks, 42 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 ----------------------------------'

Comparison explanation

Execution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:

  • Welch test with statistical test for significance of 5%
  • Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).
