This does not have a reasonable way of inferring the underlying name. For zero value it falls back to base of executable pathname.

This result was mistakenly unused resulting in incorrect identifiers for artifacts with duplicate dependencies.

The struct turned out not necessary during initial implementation but was not unwrapped into its single string field. This change replaces it with the underlying string and removes the indirection.

This makes overriding hakurei easier. Also avoids building hakurei twice since nix does that for some reason.

An upcoming improvement in the container init makes the current host net check return the same result for both cases. This change

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.

The cure is condemned at the point of cancellation and all of its state is destroyed by the deferred cleanup, so it makes little sense to wait for it much.

This removes all but the /work/ auto overlay behaviour and enables much greater flexibility. This also renames ExecContainerPath to ExecPath so it is easier to type.

These are not encoded in the format, they are rejected here to serve as a check for cache since checksum is computed for every directory.

This directly submits the upperdir to cache. It is primarily used in bootstrapping where tools are limited and should not be used unless there is a very good reason to.

This works around the fact that execArtifact always creates the work directory when setting up the bind mount.

This sets up the last Artifact to target /tmp as a writable overlay mount backed by the host side temp directory. This is useful for an Artifact containing source code to be built for another Artifact for example.

Only write should be cleared here, clearing execute causes execArtifact to be unable to start anything since no Artifact is able to produce an executable file.

This makes it possible to use an Artifact as root without arranging for directory creation in the Artifact ahead of time.

This optionally attaches an output checksum to an execArtifact and enables host networking for the resulting container.

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 runs a program in a container environment. Artifacts can be made available to the container, they are cured concurrently and mounted in order.

This change adds a method to check on-disk cache consistency and destroy inconsistent entries as they are encountered. This primarily helps verify artifact implementation correctness, but can also repair a cache that got into an inconsistent state from curing a misbehaving artifact, without having to destroy the entire cache.

This makes the checksum consistent with the final resting state of artifact directories without incurring the cost of an extra pair of chown syscalls.

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.
