Parameter values are split with `maxSplits: 1`, so values containing `\u003d` (e.g., `token\u003dabcd\u003d\u003d`) are no longer truncated.\n3.

After `./start-connect-server.sh`, the job now\nwaits (up to 60 seconds) until `Spark Connect server started at` appears in\n`/tmp/spark/logs/*.out` before running the tests.\n\n### Why are the changes needed?\n\nThese two jobs pass `--packages org.apache.iceberg:...`, which resolves and downloads the\nIceberg jars at server startup. This creates a large window where the Spark Connect server is\nnot yet listening. Since the Swift client has no connection retry, `swift test` can start before\nthe server is ready and fail immediately, making the jobs flaky.

The Swift client previously supported only column *renaming* (`withColumnRenamed`) and had no way to add or replace a column from a computed expression. This change improves API parity with PySpark/Spark SQL.\n\n### Does this PR introduce _any_ user-facing change?\n\nYes. This adds two new public `DataFrame` APIs.\n\n```swift\nlet df \u003d try await spark.range(1)                    // columns: [id]\ntry await df.withColumn(\"b\", \"id + 1\").show()        // columns: [id, b]\ntry await df.withColumns([\"b\": \"id + 1\",\n                          \"c\": \"id * 2\"]).show()     // columns: [id, b, c]\n```\n\n### How was this patch tested?\n\nPass the CIs.\n\n### Was this patch authored or co-authored using generative AI tooling?\n\nGenerated-by: Claude Code (Claude Opus 4.8)\n\nCloses #405 from dongjoon-hyun/SPARK-57302.\n\nAuthored-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\nSigned-off-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\n"

      "message": "[SPARK-57156] Harden fork CI status workflows against run/check-run race and pagination\n\n### What changes were proposed in this pull request?\n\nPort the hardening fixes from Apache Spark (SPARK-57154, SPARK-57155) to this\nrepository\u0027s `notify_test_workflow.yml` and `update_build_status.yml`, which were\nintroduced here as a copy of Spark\u0027s fork-based CI status mechanism (SPARK-57151).\n\n`notify_test_workflow.yml`:\n\n1. When listing the fork\u0027s workflow runs, instead of blindly taking the most\n   recent run (`workflow_runs[0]`) and throwing if its `head_sha` does not match\n   the PR head SHA, retry (up to 3 times, 3s apart) looking for the run whose\n   `head_sha` matches the PR head SHA. The listing endpoint orders by most recent,\n   so the run for the just-pushed SHA may not be registered yet and a stale run\n   from a previous push could be returned.\n\n2. When resolving the `Run / License Check` check-run id (used only to render a\n   Check-run view link instead of the Actions view, see SPARK-37879), a missing\n   check-run no longer throws. The check-run materializes later than the workflow\n   run, especially when the matrix is queued, so this is now best-effort: if it\n   cannot be found, the `Build` check is still created pointing at the Actions\n   run URL.\n\n`update_build_status.yml`:\n\n3. List a commit\u0027s check-runs with `github.paginate(..., per_page: 100)` instead\n   of a single un-paginated request, matching `notify_test_workflow.yml`. The\n   default page size is 30, so the target `Build` check could fall off the first\n   page on a SHA that accumulates more check-runs than that.\n\n4. Wrap `JSON.parse(cr.output.text)` in try/catch and `continue` on failure, so a\n   `Build` check with empty or malformed output text does not abort the whole\n   scheduled run and block updates for every PR queued behind it.\n\n### Why are the changes needed?\n\nThe race conditions previously left a PR with no `Build` check at all, and the\nscheduled updater only syncs existing checks, so the PR had no status reported\nuntil the next push. The pagination and parsing issues silently block status\nupdates, leaving PRs stuck in `queued`.\n\n### Does this PR introduce _any_ user-facing change?\n\nNo. CI infrastructure only.\n\n### How was this patch tested?\n\nStatic verification: the embedded `actions/github-script` bodies pass\n`node --check`, and the workflow YAML parses.\n\n### Was this patch authored or co-authored using generative AI tooling?\n\nGenerated-by: Claude Code (Claude Opus 4.8)\n\nCloses #402 from viirya/SPARK-57156-harden-ci-status.\n\nAuthored-by: Liang-Chi Hsieh \u003cliangchi.hsieh@databricks.com\u003e\nSigned-off-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\n"

This matches the Apache Spark main repository.\n\n### Does this PR introduce _any_ user-facing change?\n\nNo. CI and documentation only.\n\n### How was this patch tested?\n\nStatic verification of the cross-workflow wiring: the `Run / License Check`\ncheck-run name, the shared `Build` check name, and the `run_id` passed from\n`notify` to `update`. Full behavior takes effect only after merge to `main`, since\nthe `pull_request_target`/`schedule` workflows and `main`-pinned URLs resolve from\nthe default branch.\n\n### Was this patch authored or co-authored using generative AI tooling?\n\nGenerated-by: Claude Code (Claude Opus 4.8)\n\nCloses #399 from dongjoon-hyun/SPARK-57151.\n\nAuthored-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\nSigned-off-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\n"

However, there is no CI coverage that verifies the Iceberg integration (`DataFrameWriterV2Tests`, `IcebergTest`) against Spark 4.1. This PR closes that gap so that regressions affecting the Spark 4.1 + Iceberg combination are caught in CI.\n\n### Does this PR introduce _any_ user-facing change?\n\nNo.\n\n### How was this patch tested?\n\nPass the CIs with the new `integration-test-mac-spark41-iceberg` job.\n\n### Was this patch authored or co-authored using generative AI tooling?\n\nGenerated-by: Claude Opus 4.7\n\nCloses #387 from dongjoon-hyun/SPARK-57059.\n\nAuthored-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\nSigned-off-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\n"

This catches Linux/JVM-specific regressions earlier in CI.\n\n- The new job starts the Spark Connect server from the official `apache/spark:4.2.0-preview5-scala` Docker image with `-c spark.sql.timeType.enabled\u003dtrue`, mirroring the configuration used by the existing `integration-test-mac-spark42` job. Unlike `integration-test-ubuntu-spark41`, which uses GitHub Actions\u0027 `services:` block, this job starts the container explicitly with `docker run -d` because GitHub Actions `services:` does not support passing CMD arguments (such as `-c spark.sql.timeType.enabled\u003dtrue`) to the entrypoint.\n\n### Does this PR introduce _any_ user-facing change?\n\nNo.\n\n### How was this patch tested?\n\nPass the CIs with the newly added test coverage.\n\n### Was this patch authored or co-authored using generative AI tooling?\n\nGenerated-by: Claude Opus 4.7\n\nCloses #365 from dongjoon-hyun/SPARK-56788.\n\nAuthored-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\nSigned-off-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\n"

The code snippets in `GettingStarted.md` and `SparkSession.md` will not compile as written, which is misleading for new users following the docs. The other items are typos and wording polish.\n\n### Does this PR introduce _any_ user-facing change?\n\nNo. Documentation-only changes.\n\n### How was this patch tested?\n\nManually reviewed the diffs and cross-checked the documented APIs against their definitions in `SparkSession.swift`, `DataFrame+Actions.swift`, and `DataFrame+Transformations.swift` to confirm the corrected `async`/`throws` annotations.\n\n### Was this patch authored or co-authored using generative AI tooling?\n\nGenerated-by: Claude Opus 4.7\n\nCloses #364 from peter-toth/SPARK-56753-documentation-fixes.\n\nAuthored-by: Peter Toth \u003cp_toth@apple.com\u003e\nSigned-off-by: Peter Toth \u003cp_toth@apple.com\u003e\n"

We should use the stable release image instead of the nightly build for CI reliability and consistency with other jobs that use `swift:6.2`.\n\n- https://www.swift.org/blog/swift-6.3-released/\n\n### Does this PR introduce _any_ user-facing change?\n\nNo.\n\n### How was this patch tested?\n\nCI should pass with the official `swift:6.3` image.\n\n### Was this patch authored or co-authored using generative AI tooling?\n\nGenerated-by: Claude Code (Claude Opus 4.6)\n\nCloses #338 from dongjoon-hyun/SPARK-56196.\n\nAuthored-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\nSigned-off-by: Dongjoon Hyun \u003cdongjoon@apache.org\u003e\n"
