This enables a FileArtifact implementation to specify whether its resulting file should be executable. This change also implements shebang and ELF magic checks in the file artifact.

Inputs is more correct than dependencies in the current terminology.

This should hopefully provide good separation between the artifact curing backend implementation and the (still work in progress) language. Making the IR parseable also guarantees uniqueness of the representation.

Avoid living under the default user agent and be at the mercy of some IDS.

This alleviates scheduler overhead when curing many artifacts.

This uses the new measured reader provided by Cache. This should make httpArtifact zero-copy.

This will be fully implemented in httpArtifact in a future commit.

This eliminates duplicate identifier computations. The new implementation also significantly reduces allocations while computing identifier for a large dependency tree.

This makes verbose messages much more useful.

This removes the left over embedded contexts.

This imposes a hard upper limit to concurrency during dependency satisfaction and moves all dependency-related code out of individual implementations of Artifact. This change also includes ctx and msg as part of Cache.

This was using the old pre-KnownChecksum function signature. It did not affect correctness since httpArtifact performs internal validation to avoid the strict mode vfs roundtrip, but it prevented content-addressed cache hits.

This cleans up the function signature and makes backwards compatible API changes possible.

This allows for more flexibility during implementation. The use case that required this was for expanding single directory tarballs.

The previous implementation exposes arbitrary user input to the cache as an identifier, which is highly error-prone and can cause the cache to enter an inconsistent state if the user is not careful. This change replaces the implementation to compute identifier late, using url string as params.

This moves all cache I/O code to Cache. Artifact now only contains methods for constructing their actual contents.

This method is for the most common use case, and in actual use there will always be an associated context.

This provides infrastructure for computing a deterministic identifier based on current artifact kind, opaque parameters data, and optional dependency kind and identifiers.

This is useful for downloading source tarballs from the internet.
