Pull request overview

Updates the CondaLock detector pipeline to populate per-package digest fields (md5/sha256) into scan manifests, and adjusts typed component identity behavior to incorporate digests.

Changes:

  • Extend CondaDependencyResolver to extract md5/sha256 from conda-lock package hash maps and populate them onto created components.
  • Add Md5/Sha256 fields to PipComponent and Sha256 to CondaComponent, and update ComputeBaseId() logic to include digests.
  • Expand CondaLockComponentDetectorTests to assert digests are populated for both Conda and Pip components.

ComputeBaseId() now incorporates Sha256/Md5 into the Pip component identity. Since Component.Id is used as the stable key in manifests and dependency graphs, this is a breaking change: the same package/version can now produce different IDs depending on whether a digest is present, and verification tests that diff manifests across versions will fail. If the goal is to surface digests in output without changing identity semantics, consider keeping BaseId as name version - type and emitting digests as separate fields (or via extended ID properties if the ID format must include them).

var digestSuffix = string.Empty;
if (!string.IsNullOrEmpty(this.Sha256))
{
digestSuffix = $" {this.Sha256}";
}

Md5/Sha256 are mutable (set;) but are also used to compute (and then cache) BaseId/Id. If these properties are ever set/changed after the component has been registered (or after Id has been accessed once), the cached ID won’t reflect the updated digest, causing inconsistent graph keys. To prevent this class of bugs, consider making these init-only or constructor-set so identity inputs can’t change after creation.

ComputeBaseId() now always interpolates this.Sha256. When Sha256 is null/empty (e.g., callers like the Linux conda artifact factory don’t pass it), this changes the resulting component ID string (extra whitespace) compared to previous releases, which can break manifest diffing and component de-duplication. Consider building the ID from non-empty parts (or conditionally appending sha256 only when present) so IDs are stable when sha256 isn’t available.

Suggested change
protected override string ComputeBaseId() => $"{this.Name} {this.Version} {this.Build} {this.Channel} {this.Subdir} {this.Namespace} {this.Url} {this.MD5} {this.Sha256} - {this.Type}";
protected override string ComputeBaseId()
{
var baseIdWithoutSha256 = $"{this.Name} {this.Version} {this.Build} {this.Channel} {this.Subdir} {this.Namespace} {this.Url} {this.MD5}";
if (string.IsNullOrEmpty(this.Sha256))
{
return $"{baseIdWithoutSha256} - {this.Type}";

Sha256 is ignored when null, but MD5 is still always serialized. If MD5 is missing for a package, this will emit "mD5": null in scan manifests, which is inconsistent with the new sha256 behavior and may create noisy diffs. Consider adding JsonIgnore(Condition = WhenWritingNull) to MD5 as well (or otherwise aligning null-handling for both digest fields).

Passing md5/sha256 into CondaComponent will make the component ID platform/artifact-specific (hashes differ per platform/build), reintroducing the duplicate-component scenario the comment above is trying to avoid by omitting URL. If the intent is still to dedupe the same name/version across platforms, consider storing hashes as metadata fields but keeping them out of the identity used for Component.Id (or otherwise explicitly scoping identity changes to the desired cases).

Suggested change

return new CondaComponent(package.Name, package.Version, null, package.Category, null, null, null, null, null);
