ci(e2e): read adopted DerivedData over parallel ranges - #14051
Merged
Merged
Conversation
The first consumer (run 35896881813) timed out after 10 minutes still downloading the 1.9 GB archive over one `gh api` connection, then compiled cold. Adoption now uses the fleet's ranged artifact transport, verifies the provider digest before unpacking, and allows 15 minutes for download and extraction.

`actions/upload-artifact` to leave enough headroom for the ZIP wrapper, keeping
the resulting artifact below `MAX_BYTES` so it remains reusable.

Follow-up to #14016. The first adopting build, run 35896881813, found main's published DerivedData: a 1.9 GB archive from producer run 35893020090. It then hit the 10-minute step timeout while still downloading, because
gh api …/zipreads the blob over one connection at about 2 MB/s on the macOS fleet. The build fell back to cold, so that run does not measure incremental compile time.Adoption now downloads through
parallel_artifact_download.download_zip, the ranged transport the app-host consumers already use. It checks the ZIP against the artifact's provider SHA-256 before unpacking, and the step allows 15 minutes: the transport's 6-minute deadline plus extraction.Validation. A new test shows a digest mismatch raises before anything is extracted. All linux-guard tests pass locally and actionlint is clean. Not yet measured: transfer time and the incremental compile. After merge, a test-only dispatch on top of the producer's revision measures both.

Speeds up warm e2e cache adoption so the build no longer times out and falls back to cold compilation.
The first adoption (run 35896881813) hit the 10-minute step timeout still downloading the 1.9 GB archive, since
gh api …/zipreads the blob over one connection at ~2 MB/s on the macOS fleet. Adoption now downloads through the rangedparallel_artifact_download.download_ziptransport the app-host consumers already use, verifies the ZIP against the artifact's provider SHA-256 before unpacking, allows 15 minutes for download and extraction, and skips artifacts lacking asha256:digest. Publishing now rejects archives above 7.5 GiB to leave headroom under the transport's 8 GiB ZIP limit. A new test confirms a digest mismatch raises before anything is extracted. Transfer time and incremental compile time are not yet measured; a test-only dispatch after merge measures both.Written for commit 14487f2. Summary will update on new commits.
