pdftract-220e Verification Note

Bead

pdftract-220e: Argo WorkflowTemplate: pdftract-build-binaries (10 archives = 5 triples × 2 feature variants)

Work Completed

1. Created WorkflowTemplate

File: jedarden/declarative-config/k8s/iad-ci/argo-workflows/pdftract-build-binaries.yaml

Commit: ae2c9b2

2. Template Features

Matrix Build (10 items)

  • 5 target triples × 2 feature variants (default, full)
  • Uses withItems DAG pattern with continueOn: failed so one triple failure doesn't block others
  • Each build runs in parallel with a 3600s (60 min) activeDeadlineSeconds

Target Triples

Triple Cross Image Strip Command
x86_64-unknown-linux-musl ghcr.io/cross-rs/x86_64-unknown-linux-musl:main strip
aarch64-unknown-linux-musl ghcr.io/cross-rs/aarch64-unknown-linux-musl:main aarch64-linux-gnu-strip
x86_64-apple-darwin ghcr.io/cross-rs/x86_64-apple-darwin:main x86_64-apple-darwin-strip (osxcross)
aarch64-apple-darwin ghcr.io/cross-rs/aarch64-apple-darwin:main aarch64-apple-darwin-strip (osxcross)
x86_64-pc-windows-gnu ghcr.io/cross-rs/x86_64-pc-windows-gnu:main strip

Build Process

  1. Setup step: Clones repo, extracts SOURCE_DATE_EPOCH from tag commit
  2. Cross-compilation: Uses cross tool with --locked --frozen flags
  3. Strip: Target-appropriate strip command (musl-strip, osxcross strip, mingw strip)
  4. Reproducibility: SOURCE_DATE_EPOCH set from tag commit timestamp
  5. Archive packaging:
    • Unix: .tar.gz format
    • Windows: .zip format
    • Contents: stripped binary, LICENSE-MIT, LICENSE-APACHE, README.md, CHANGELOG excerpt
  6. Artifact output: Argo artifacts for downstream pdftract-github-release template

Archive Naming

  • Default features: pdftract-vX.Y.Z-<triple>.tar.gz
  • Full features: pdftract-full-vX.Y.Z-<triple>.tar.gz

Special Features

  • osxcross SDK: Volume-mounted from osxcross-sdk Secret (readOnly)
  • Binary size budget: Warns if default x86_64-unknown-linux-musl exceeds 4 MB
  • CHANGELOG excerpt: Python script extracts version section from CHANGELOG.md
  • Cargo cache: 50Gi PVC for warm cache across builds
  • podGC: OnPodCompletion: Pods deleted immediately after completion

3. Resource Limits

  • Requests: 2000m CPU, 4Gi memory
  • Limits: 4000m CPU, 8Gi memory
  • ActiveDeadlineSeconds: 3600 (60 min) per build

4. Parameters

Parameter Description
repo GitHub repo (default: jedarden/pdftract)
branch Branch to clone (default: main)
tag Git tag (e.g., v0.1.0)
version Version extracted from tag
commit-sha Full commit SHA of the tag

Acceptance Criteria Status

Criterion Status Notes
WorkflowTemplate file lands at correct path PASS k8s/iad-ci/argo-workflows/pdftract-build-binaries.yaml
ArgoCD reconciles template into argo-workflows namespace EXPECTED ArgoCD auto-syncs from declarative-config; template will appear after sync
Test workflow produces 10 archives NOT TESTED Requires actual tag trigger; infra verification deferred
Two runs produce byte-identical archives NOT TESTED Requires actual build; SOURCE_DATE_EPOCH is set for reproducibility
One triple failure does NOT cancel others PASS continueOn: failed: true set on withItems
Wall-clock <= 12 min for slowest variant NOT TESTED Requires actual build; 60 min timeout allows ample margin

WARN Items

  1. kubectl not available: Could not directly verify ArgoCD sync via kubectl. The ArgoCD API also returned no output. Sync status is expected based on ArgoCD's auto-sync behavior from the declarative-config repo.

  2. No test workflow submitted: The acceptance criteria requiring actual test workflow submission and reproducibility check is deferred until the first milestone tag. The template is structurally complete and follows all patterns from sibling templates.

PASS Items

  1. Template structure: Valid YAML with proper Argo WorkflowTemplate schema
  2. Matrix build: 10 items (5 triples × 2 variants) using withItems
  3. Cross-compilation: Correct cross images per triple
  4. osxcross integration: Volume mount from Secret for macOS builds
  5. Reproducibility: SOURCE_DATE_EPOCH set from tag commit
  6. Archive packaging: Correct layout with licenses, README, CHANGELOG excerpt
  7. Archive formats: .tar.gz for Unix, .zip for Windows
  8. Artifact outputs: Argo artifacts for downstream consumption
  9. Fault tolerance: continueOn: failed prevents single-triple failures from blocking others
  10. Cargo.lock policy: --locked --frozen flags enforced
