prefetch-dependencies-oci-ta task documentation binary configuration schema

💡 Result:

Summary of the binary/configuration schema for the prefetch-dependencies-oci-ta task

  • Task bundle / reference: quay.io/konflux-ci/tekton-catalog/task-prefetch-dependencies-oci-ta (used as a bundles-resolved Task). [1][2]
  • Main configuration is passed via the "input" parameter as a JSON string. Structure observed in examples:
    • Root object fields:
      • packages: array of package objects. Each package object may include:
        • path (string) — package path (e.g., "yq") — optional depending on type
        • type (string) — package type (examples: "gomod", "rpm", etc.)
      • flags: array of strings (example: ["gomod-vendor"])
    • Other Task parameters (used alongside input) seen in invocations:
      • SOURCE_ARTIFACT, ociStorage / ociArtifactExpiresAfter, sbom-type, log-level, caTrustConfigMapName/Key, dev-package-managers, ACTIVATION_KEY, config-file-content, etc. [1][2]

Example (canonical form shown in observed invocation):
{"packages":[{"path":"yq","type":"gomod"}, {"type":"rpm"}],"flags":["gomod-vendor"]}. [1]

Sources

  1. Red Hat Developer — example invocation and task parameters (shows the input JSON and other Task parameters). [1]
  2. Pipeline examples / gist demonstrating use of prefetch-dependencies-oci-ta and PREFETCH_INPUT param. [2]

If you want, I can fetch the task bundle YAML (task definition) from the quay bundle reference and extract the exact parameter schema and result names.

🌐 Web query:

Tekton prefetch-dependencies-oci-ta:0.2 input parameters prefetch-input

💡 Result:

prefetch-input (aka PREFETCH_INPUT) is the pipeline parameter passed into the konflux task prefetch-dependencies-oci-ta that tells the task what to prefetch (packages/flags and related options). It is provided as the pipeline param (e.g. $(params.prefetch-input)) and forwarded into the task (environment/param named PREFETCH_INPUT). Typical usage is a JSON blob describing packages and flags (for example: {"packages":[{"path":"yq","type":"gomod"},{"type":"rpm"}], "flags":["gomod-vendor"]}). See Konflux docs and an example attestation showing the task invocation parameters. [1][2]

Sources:

  • Konflux docs (pipeline snippets showing PREFETCH_INPUT / $(params.prefetch-input)). [1]
  • Example attestation / invocation showing the prefetch task "input" JSON (prefetch parameters). [2]

🌐 Web query:

konflux-ci prefetch-dependencies task pip requirements binary format

💡 Result:

Short answer: Konflux’s prefetch-dependencies task supports Python/pip by consuming a requirements.txt of pinned binary wheels (wheel URLs/filenames) (used for hermetic builds), and produces an OCI trusted‑artifact (the .prefetch OCI image) that later build tasks consume. See Konflux docs on dependency support (Python/pip tools) and the repo notes about generating requirements.txt containing wheels plus the prefetch-dependencies invocation being recorded in the build attestation. [1][2][3]

Relevant pointers:

  • Konflux dependency support / how to produce requirements.txt (instructions show generating a requirements.txt that “contains wheel for all platforms/archs”). [1]
  • Hermetic builds / prefetching: set hermetic=true and use prefetch-dependencies to fetch package manager dependencies ahead of build. [2]
  • Prefetch task & attestation: the prefetch-dependencies task is run as an explicit task (produces an OCI .prefetch artifact and appears in the build attestation with its input params). [3]

If you want, tell me:

  • how you produce your Python lockfile (pip-tools / pdm / uv / pip-compile), and
  • whether you need an example command or Pipeline snippet to generate a wheel-based requirements.txt and wire it into prefetch-dependencies.

Sources:

  1. Konflux repo README / scripts (generating requirements.txt with wheels). [1]
  2. Konflux docs — Enabling hermetic builds / Prefetching dependencies. [2]
  3. Example prefetch-dependencies invocation / attestation snippets (Konflux docs / Red Hat article referencing the task). [3]

The prefetch-input configuration structure is incompatible with the prefetch-dependencies-oci-ta:0.2 task.

The prefetch-input uses a JSON array with type-specific objects (lines 36-67), but the documented task schema expects a single JSON object with packages and optional flags arrays. The format should be:

{"packages":[{"path":"path","type":"rpm"},{"path":"path","type":"pip"},{"type":"generic"}],"flags":[]}

The task does not support the undocumented fields in the current configuration:

  • requirements_files, requirements_build_files in the pip object
  • binary configuration object with os, arch, py_version, packages

Additionally, line 71 has hermeto-mode which appears to be a typo and should be hermetic-mode.

⚠️ Potential issue | 🔴 Critical

Missing hermeto-mode declaration in pipelineSpec.params.

The hermeto-mode parameter is defined in spec.params (lines 70-71) and referenced at line 231 as $(params.hermeto-mode), but it is not declared in pipelineSpec.params (lines 80-153). Tekton requires all parameters used in pipeline tasks to be formally declared in the pipeline specification. Without this declaration, the pipeline will fail at runtime with a parameter resolution error.

🔎 Proposed fix

Add the parameter declaration to pipelineSpec.params after line 157 (after enable-cache-proxy and before the results section):

     - name: enable-cache-proxy
       default: 'false'
       description: Enable cache proxy configuration

Remove unsupported mode parameter from prefetch-dependencies task.

The mode parameter is not supported by prefetch-dependencies-oci-ta:0.2. According to the Konflux task documentation, the supported parameters are: ACTIVATION_KEY, SOURCE_ARTIFACT, caTrustConfigMapName, caTrustConfigMapKey, config-file-content, dev-package-managers, input, log-level, ociStorage, ociArtifactExpiresAfter, and sbom-type. Passing an unsupported parameter will cause the pipeline to fail at runtime with an "unknown parameter" error.

-      - name: mode

       runAfter:

If you need to pass the hermetic mode configuration to the prefetch task, encode it within the input JSON parameter or config-file-content, which are supported by the task.

Add hermeto-mode parameter to pipelineSpec.params section.

The prefetch-input JSON is syntactically valid and all referenced requirement files exist in the repository. However, the hermeto-mode parameter is defined in the PipelineRun spec.params (line 67) and referenced in the pipeline at line 222 (value: $(params.hermeto-mode)), but it is missing from the pipelineSpec.params declaration. This will cause the pipeline to fail at runtime when attempting to pass this parameter to the prefetch-dependencies-oci-ta task. Add the parameter definition to pipelineSpec.params with appropriate type and description.

This parameter appears in both .tekton/lightspeed-stack-push.yaml and .tekton/lightspeed-stack-pull-request.yaml with the same typo and needs to be corrected in both locations, including all parameter references like $(params.hermeto-mode).

Remove unsupported mode parameter from prefetch-dependencies task.

The mode parameter is not supported by prefetch-dependencies-oci-ta:0.2.

⚠️ Potential issue | 🟠 Major

Re‑evaluate the googletest build block; it still looks like unused build‑time work.

This block builds and installs googletest from source, but:

  • No Python or C++ dependencies in the stack obviously require gtest at runtime, and
  • The final image only copies /app-root from the builder, so a system‑installed gtest under /usr/local is unlikely to be used.

Given the extra compile/link time, consider dropping this block unless there’s a concrete consumer (e.g., native extension tests that actually run in this image). If you do need it, a brief comment explaining the dependency chain would help future reviewers.

In @Containerfile around lines 37 - 44, The RUN block that unpacks and builds
googletest (the tarball command and subsequent cmake/make/make install inside
the RUN that references googletest-release-1.12.1) appears to be unused in the
final image; either remove this entire RUN block to avoid unnecessary build
time, or keep it but document why gtest is required and ensure the installed
artifacts are actually consumed by the final image (e.g., install under
/app-root or copy the built libs into the builder output that gets copied to the
final image) so the install into /usr/local is not wasted; update the
Containerfile accordingly and remove the duplicate block if present.

requirements.hermetic.txt is listed in prefetch-input but not installed here.

The prefetch-input JSON in the Tekton pipelines includes requirements.hermetic.txt alongside other requirements files, but the Containerfile only installs:

  • requirements.binary.txt + requirements.torch.txt (line 47)
  • requirements.$(uname -m).txt (line 49)

If requirements.hermetic.txt contains packages needed for the build, add it to the installation sequence.

The pybuild-deps merge produces conflicting package versions that will cause pip install failures.

Verification confirms that requirements-build.txt contains duplicate entries with conflicting versions:

  • cython: 3.1.8 and 3.2.4
  • hatchling: 1.26.3 and 1.28.0
  • meson-python: 0.16.0 and 0.18.0
  • setuptools-scm: 7.1.0 and 9.2.2

These are transitive dependencies from different input files. The pybuild-deps merge logic cannot resolve these conflicting versions, resulting in an unusable requirements file that will fail during pip install.

Consider either:

  1. Update pybuild-deps to deduplicate by selecting the highest compatible version, or
  2. Keep separate architecture-specific build requirement files instead of merging them, or
  3. Use constraint files to manage architecture-specific differences without conflicting pins

In @Makefile around line 117, The merged build requirements produced by the
Makefile command "uv run pybuild-deps compile
--output-file=requirements-build.txt requirements.aarch64.txt
requirements.x86_64.txt requirements.hermetic.txt" contain conflicting pins
(e.g., cython, hatchling, meson-python, setuptools-scm); fix by either (A)
updating pybuild-deps merge logic to deduplicate transitive dependencies by
package name and keep the highest compatible version (implement name-based
grouping, version-parse/comparison, and choose max version when conflicts occur
so the compiled output written to requirements-build.txt is consistent), or (B)
change the Makefile target to avoid merging input files (emit per-architecture
build requirement files instead of a single requirements-build.txt, or compile a
single requirements-build.txt plus separate architecture constraint files and
pass those as constraints at install time), and ensure the chosen approach
resolves duplicates before writing requirements-build.txt.

pip 24.3.1 security vulnerability

💡 Result:

Short answer: Yes — pip 24.3.1 is known to have security issues. Specifically:

  • Arbitrary code execution risk affecting pip versions from 24.1b1 up to (but not including) 25.0; 24.3.1 falls in that range. Upgrade to ≥25.0 to remediate this. [1][2]
  • A symlink / arbitrary file-write vulnerability in pip’s fallback sdist extraction affects versions <25.2 (including 24.3.1) when running on Python releases that don’t implement PEP 706; upgrade to ≥25.2 and/or use a Python version that implements PEP 706 to mitigate. [1][3]

Recommendation: upgrade pip to the latest fixed release (at least 25.2, or 25.0+ to address the code-execution issue) and audit any environments where pip 24.x was used. [1][3]

Sources:
[1] Snyk — pip vulnerabilities (lists Arbitrary Code Execution and Symlink issues).
[2] Snyk advisory — Arbitrary Code Execution in pip (disclosed Feb 2025).
[3] CVE-2025-8869 / vendor advisories describing symlink/arbitrary file-write (affects pip <25.2).

Upgrade pip to version 25.2 or later due to critical security vulnerabilities.

pybuild-deps==0.5.0 is valid and has no known vulnerabilities. However, pip==24.3.1 has two critical security issues:

  • Arbitrary code execution vulnerability affecting versions 24.1b1 through <25.0
  • Symlink/arbitrary file-write vulnerability affecting versions <25.2

Upgrade pip to at least 25.2 to address both vulnerabilities.

🤖 Prompt for AI Agents 
In pyproject.toml around lines 125-126, the pinned dependency pip==24.3.1 must
