From e0e805ebb5722352725c574f4165c0ca98a89e22 Mon Sep 17 00:00:00 2001 From: omid-aignostics Date: Wed, 15 Jul 2026 10:44:39 +0200 Subject: [PATCH 1/7] perf(application): raise run prepare checksum read buffer to 8MB The CRC32C checksum in run prepare read source slides in 1KB chunks, turning a multi-GB WSI into ~millions of tiny reads whose per-read overhead dominates on slow/high-latency storage (USB, network drives). A local benchmark measured ~42x faster full-file hashing at 8MB vs 1KB. Introduce APPLICATION_RUN_METADATA_CHECKSUM_CHUNK_SIZE (8MB) and use it in the prepare checksum loop. Checksum result is unchanged; 8MB stays well within the 8GB RAM floor.

Without a root component, all ~400 dependencies are emitted as unanchored nodes, forcing Ketryx's synchronous /builds endpoint to do excessive dependency-relation work; it runs for minutes and returns HTTP 500. This reproduced deterministically per commit (e.g. commit a1b4931 failed 10+ retries over two days) and was blocking Ketryx build reporting for the release. Ketryx flagged the missing root component as the root cause. Verified locally: the regenerated SBOM now has root component `aignostics` (type: application) anchoring 67 direct dependencies.

Ketryx then attempts to fetch the PR as a Code Change Request (CCR) and returns HTTP 500 when that fetch fails — which per Ketryx is due to the PAT lacking the required GitHub permissions. This failed the build even though the build and SBOM were reported successfully server-side, blocking the release. We do not use the CCR / item-association feature (check-item-association is false), so override GITHUB_REF_NAME to the branch name (which never ends in `/merge`) for the report step, making the action send no changeRequestNumber and skip the failing CCR fetch. Root cause identified by Ketryx (Anton) in the PYSDK support thread.

Rewrite GITHUB_REF_NAME via $GITHUB_ENV (which can override defaults) to the branch name so no changeRequestNumber is sent. Additionally mark the report step continue-on-error on pull_request runs as a safety net: the build and SBOM land in Ketryx regardless of the 500, so a Ketryx-side failure must not block PR CI. On push/tag runs (releases) the ref never ends in "/merge" and continue-on-error is false, so the gate is still enforced.
