Run the input_selection e2e specs in parallel while keeping every other e2e suite serial, cutting the dominant contributor to e2e wall-clock time. Each input_selection spec now derives a token unique across parallel processes (GinkgoParallelProcess + atomic counter) and threads it through its namespaces, namespace globs and pod-label selectors so concurrently running specs no longer collide on: - the previously fixed "clo-test-frontend" namespace (recreated per spec) - the shared "clo-test*" namespace glob - pod labels used by application input selectors Inputs and verifiers are now builder funcs of the per-spec namespaces rather than shared constants. All other e2e suites are marked Serial so only input_selection spreads across worker processes, and the CI script drives the suite with the ginkgo CLI (the only way Ginkgo v2 runs specs in parallel). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Allow the lokistack e2e specs to run in parallel (ginkgo -p), building on the parallel-execution foundation from the input_selection change: - Deploy the shared resources (minio, loki operator, reader cluster role) once in SynchronizedBeforeSuite; give each spec its own namespace, minio bucket and LokiStack via a token unique across parallel processes. - Retry lokistack queries on transient errors instead of failing on the first one: a gateway can report Available while observatorium-api is not yet serving authenticated queries, returning 401 or an HTML 5xx page while multiple LokiStacks warm up concurrently. Return the last query error on timeout so failures stay diagnosable. - Skip the loki-operator install when the operator deployment is already available (pre-installed or left from a prior run), and avoid registering cleanups that would delete an operator we did not create. - Cap parallelism at --procs=3 to keep concurrent LokiStacks from overwhelming the shared cluster's data plane.

Preserve ownership when an existing operator is unavailable.
If the Loki operator deployment exists but is temporarily unavailable, this check falls through to the installation path. That path registers cleanup that deletes the shared openshift-operators-redhat namespace, although this framework did not create the existing operator. Wait for an existing deployment separately. Treat only a confirmed NotFound result as a reason to install, and register namespace cleanup only when the framework owns that namespace. (onsi.github.io)

The lokistack specs each stand up a full LokiStack, a collector DaemonSet, minio and a log generator. Running all `--procs` of them at once starves the shared CI cluster and logs fail to ingest within the query timeout. Throttle concurrency with an flock-based counting semaphore (default 2, overridable via LOKI_E2E_MAX_CONCURRENT_SPECS) acquired in the suite BeforeEach and held through teardown. ginkgo -p runs workers as separate processes, so this is enforced across processes rather than by lowering --procs in hack/test-e2e-from-ci-bundle.sh. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Deploy the application log generator from each spec that needs it rather than in BeforeEach, and collect application logs via a per-spec input scoped to the generator's namespace instead of the cluster-wide application input. Under parallel execution every collector previously ingested all application pods cluster-wide, so a spec's LokiStack received other parallel specs' pods (e.g. another process's lokistack gateway), inflating queries and starving ingestion. Scoping the input to the generator namespace keeps specs isolated; specs that forward only receiver inputs (http/syslog/trace) no longer deploy an unused generator. Audit and infrastructure remain cluster-wide. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Handle OpenFile errors instead of silently retrying forever.
If os.OpenFile fails for a persistent reason, such as a read-only TMPDIR or a permission error, the loop does continue for every slot. It then sleeps and retries without any bound. The spec hangs until the Ginkgo suite timeout, and the cause is never reported. Fail fast with Expect, as is already done for MkdirAll.

Wait for the trace namespace before releasing the concurrency slot.
e2e.Cleanup() submits delete requests but does not wait for the trace namespace or pod to terminate. The slot is released after AfterEach, so another spec can start while trace cleanup is still in progress.
