fix(profiling): skip TLS init for non-HTTPS endpoints by r1viollet · Pull Request #1796 · DataDog/libdatadog

r1viollet · 2026-03-25T16:52:42Z

What does this PR do?

Since 9a61cae (perf(profiling): cache TLS in ProfileExporter::new, 2026-02-27), TLS configuration is initialized unconditionally in ProfileExporter::new(), even when the endpoint uses plain HTTP (e.g. agent mode at http://:8126), unix sockets, or named pipes.

On Linux this eagerly loads the system CA certificate store via rustls-platform-verifier. In minimal container images (e.g. a bare ubuntu:20.04 without the ca-certificates package), there are no certs to load, so the call fails with:

failed to initialize TLS configuration: unexpected error:
No CA certificates were loaded from the system

This surfaced in ddprof after the libdatadog v29 upgrade: the profiler targets the Datadog agent over HTTP and has no reason to touch the cert store at all.

Fix: only call cached_tls_config() and apply tls_backend_preconfigured() when the endpoint scheme is "https". All other schemes (http, unix, windows, file) bypass TLS initialization entirely.

Motivation

Avoid the following error:

Failure creating exporter - ddog_prof_Exporter_new failed: failed to initialize TLS configuration: unexpected error: No CA certificates were loaded from the system

Additional Notes

NA

How to test the change?

We need a docker container that has no certificates.
Possibly ubuntu 20

Comparison

Benchmark execution time: 2026-03-26 09:04:10

Comparing candidate commit 407c70b in PR branch r1viollet/fix_certificate_issue with baseline commit b1d5bcf in branch main.

Found 0 performance improvements and 2 performance regressions! Performance is the same for 60 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 ----------------------------------'

Since 9a61cae (perf(profiling): cache TLS in ProfileExporter::new, 2026-02-27), TLS configuration is initialized unconditionally in ProfileExporter::new(), even when the endpoint uses plain HTTP (e.g. agent mode at http://<host>:8126), unix sockets, or named pipes. There are two layers to the problem: 1. Our cached_tls_config() calls rustls-platform-verifier which eagerly loads the system CA store on Linux. 2. Even without our call, reqwest::ClientBuilder::build() also attempts to initialize its own TLS backend (loading system certs) unless a preconfigured TLS config is provided. Both fail with the same error in minimal container images (e.g. bare ubuntu:20.04 without the ca-certificates package): failed to initialize TLS configuration: unexpected error: No CA certificates were loaded from the system This surfaced in ddprof after the libdatadog v29 upgrade: the profiler targets the Datadog agent over HTTP and has no reason to touch the cert store at all. Fix: - For HTTPS endpoints, use the existing cached platform TLS config (loads system CA certs via rustls-platform-verifier). - For all other schemes (http, unix, windows, file), provide reqwest with a minimal TLS config that has an empty root store. This prevents reqwest from loading system certs itself, while still giving it a valid TLS backend. TLS is never negotiated on these transports anyway. Verified with a Docker repro: ubuntu:22.04 after `dpkg --force-depends --purge ca-certificates`, all 5 exporter_e2e tests pass with the fix and fail without it. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>

Adds a CI job that runs the exporter_e2e tests inside a container with no CA certificates, reproducing the environment (bare ubuntu:20.04) that exposed the regression from 9a61cae. The job follows the same pattern as cross-centos7: mount the runner's Rust toolchain and pre-fetched cargo cache so the container needs no network access, then run the tests in an environment that would have caught the bug. Docker image layers are cached via GitHub Actions cache. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>

I did not add junit visibility to this test, is this required ?

# What does this PR do? test_crash_tracking_bin_sigchld_exec deadlocks on CentOS 7, causing nextest runs to hang for 50+ minutes. Mark it #[ignore] to unblock CI, and add a 60s nextest timeout as a safety net for --include-ignored runs. # Motivation Allow following [PR](#1796) to pass Job was stuck [here](https://github.com/DataDog/libdatadog/actions/runs/23585387299/job/68677153999?pr=1796) # Additional Notes - Normal CI run: the test is #[ignore] so it's skipped entirely — the timeout never triggers - If someone runs with --include-ignored: after 60s nextest sends SIGTERM (then SIGKILL after a grace period) and reports the test as TIMEOUT — which is a failure # How to test the change?

This works in PHP and fixes the issue when no root CA is available.

# What does this PR do? Since 9a61cae (perf(profiling): cache TLS in ProfileExporter::new, 2026-02-27), TLS configuration is initialized unconditionally in ProfileExporter::new(), even when the endpoint uses plain HTTP (e.g. agent mode at http://<host>:8126), unix sockets, or named pipes. On Linux this eagerly loads the system CA certificate store via rustls-platform-verifier. In minimal container images (e.g. a bare ubuntu:20.04 without the ca-certificates package), there are no certs to load, so the call fails with: failed to initialize TLS configuration: unexpected error: No CA certificates were loaded from the system This surfaced in ddprof after the libdatadog v29 upgrade: the profiler targets the Datadog agent over HTTP and has no reason to touch the cert store at all. Fix: only call cached_tls_config() and apply tls_backend_preconfigured() when the endpoint scheme is "https". All other schemes (http, unix, windows, file) bypass TLS initialization entirely. # Motivation Avoid the following error: ``` Failure creating exporter - ddog_prof_Exporter_new failed: failed to initialize TLS configuration: unexpected error: No CA certificates were loaded from the system ``` # Additional Notes NA # How to test the change? We need a docker container that has no certificates. Possibly ubuntu 20 Co-authored-by: erwan.viollet <[email protected]>
