fix(ci): Address semver job issue

[gleocadie]

What does this PR do?

Adds a git clone fallback to libdd-libunwind-sys/build.rs for obtaining the libunwind source when the crate is built outside of a git repository.

The source acquisition logic is now structured as three steps:

1. If libunwind/src already exists (submodule checked out, or files copied in), do nothing.
2. If inside a git repo (.git exists), try git submodule update --init --recursive.
3. Otherwise, fall back to git clone --depth 1 of the libunwind repository directly.

Motivation

The semver-check CI job runs cargo-semver-checks --baseline-rev origin/main, which extracts the baseline source into a plain directory under target/semver-checks/git-origin_main/<commit>/. This directory has no .git — it's a raw file extraction, not a git clone or worktree.

When building the baseline version of libdd-crashtracker, cargo needs to compile its dependency libdd-libunwind-sys, which triggers build.rs. The previous implementation unconditionally ran git submodule update --init assuming it was inside a git repo, which failed with:

error: pathspec 'libdd-libunwind-sys/libunwind' did not match any file(s) known to git

This is not reproducible locally because a normal git clone properly initializes the submodule, and build.rs skips the git commands entirely when libunwind/src is already present.

Additional Notes

• This fix must land on main before other branches that modify libdd-crashtracker can pass the semver-check CI job. This is because cargo-semver-checks uses the baseline (main) version of build.rs when building the baseline, not the branch's version.
• The libunwind repo URL and branch are extracted into constants (LIBUNWIND_REPO, LIBUNWIND_BRANCH) to keep them in sync with .gitmodules.
• The git clone fallback also covers other non-git contexts such as cargo vendor or any tool that extracts crate source without preserving git metadata.

How to test the change?

git clone --no-checkout https://github.com/DataDog/libdatadog.git test-full
cd test-full
git checkout --detach origin/gyuheon0h/28.1.1
git submodule update --init --recursive -- libdd-libunwind-sys/libunwind
rm -rf target/semver-checks/
./scripts/semver-level.sh -v libdd-crashtracker main

Benchmarks

Comparison

Benchmark execution time: 2026-03-11 09:41:03

Comparing candidate commit f74acb2 in PR branch gleocadie/fix-semver-check with baseline commit b04809b in branch ``.

Found 0 performance improvements and 0 performance regressions! Performance is the same for 58 metrics, 2 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 ----------------------------------'
