…mponents` workflow - Add `TestDCGMExporterCompatibility` unit test in `e2e/components/` that downloads `dcgm-exporter` `.deb`/`.rpm` packages from PMC and verifies declared dependencies on `datacenter-gpu-manager-4-core` and `datacenter-gpu-manager-4-proprietary` match versions in `components.json` - Parse package metadata natively in Go using `blakesmith/ar` + `klauspost/compress/zstd` for `.deb` and `cavaliergopher/rpm` for `.rpm`, eliminating need for `dpkg-deb`/`rpm` CLI tools or VM infrastructure - Add `dcgm-compatibility` job to `.github/workflows/validate-components.yml` so the test runs automatically on every PR (including Renovate dependency bumps) Signed-off-by: Suraj Deshmukh <suraj.deshmukh@microsoft.com>
Cover `dcgm-exporter` compatibility check for all OS variants in `components.json` — Ubuntu 22.04 was previously missing, so a Renovate bump on that variant would bypass the version skew detection. Signed-off-by: Suraj Deshmukh <suraj.deshmukh@microsoft.com>
…n assertions Future-proof against `previousLatestVersion` being added to `components.json` — `GetExpectedPackageVersions` returns both `latestVersion` and `previousLatestVersion` when present, so asserting `len == 1` would break with a confusing error message.

Log epoch, version, and release separately when parsing RPM dependencies to verify `cavaliergopher/rpm` library correctly decomposes the EVR fields used by `formatRPMVersion`. Signed-off-by: Suraj Deshmukh <suraj.deshmukh@microsoft.com>

Pull request overview
Adds a lightweight, infra-free compatibility check to ensure dcgm-exporter package dependencies match the DCGM versions pinned in parts/common/components.json, and wires it into CI so Renovate bumps don’t bypass the validation.
Changes:
- Added
TestDCGMExporterCompatibilityine2e/components/components_test.goto download.deb/.rpmartifacts and parse dependency metadata in Go. - Added new Go module dependencies in
e2e/go.mod/e2e/go.sumto support.deb(ar+tar+zstd) and.rpmparsing. - Added a
dcgm-compatibilityjob to.github/workflows/validate-components.ymlto run the new test on every PR.

- Add `downloadWithRetry` helper with 60s `http.Client` timeout and 3 retries with exponential backoff to prevent CI hangs on transient network failures - Extract `parseDebControlField` to correctly parse RFC822-style continuation lines in `.deb` control files, where long `Depends:` values may wrap across multiple lines Signed-off-by: Suraj Deshmukh <suraj.deshmukh@microsoft.com>

What this PR does / why we need it:
Adds a
TestDCGMExporterCompatibilityunit test that validatesdcgm-exporterpackage dependencies (datacenter-gpu-manager-4-coreanddatacenter-gpu-manager-4-proprietary) match the versions pinned incomponents.json— without requiring GPU VMs or any infrastructure.Problem
The existing
Test_DCGM_Exporter_Compatibilitye2e test in the GPU E2E pipeline only triggers on changes toe2e/**or**/*.gofiles. Renovate PRs that bump DCGM package versions inparts/common/components.jsondon't match those path filters, so the compatibility check is silently skipped (as seen in #8354).Solution
