This avoids disabling the artifact until cache is reopened. The same has to be implemented for Cancel in a future change.

These are memory management and caching primitives. Having them as part of Cache is cumbersome and requires a temporary directory that is never used. This change isolates them from Cache to enable independent use.

This is cleaner than checking cpu count during cure, it is impossible to avoid impurity in both situations but this is configurable.

This is quite error-prone and causes cache inconsistency similar to the store inconsistency seen on nix when a similar condition happens. Keep this behind a flag in case it is ever beneficial.

This makes package check portable, and removes nonportable behaviour from package pkg, pipewire, and system. All other packages remain nonportable due to their nature. No latency increase was observed due to this change on amd64 and arm64 linux.

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.

This also rearranges the ident ir to be more predictable, and avoids an obvious and somewhat easy to get into inconsistent state.

Any fine-grained file-based locking here significantly hurts performance and is not part of the use case of the package. This change guarantees exclusive access to prevent inconsistent state on the filesystem.

This significantly improves scrubbing performance. Since the cache directory structure is friendly to simultaneous access, this is possible without synchronisation.

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

This is significantly more practical than keeping track of them in directory flattening format and setting this in every non-artifact implementation. Only tarArtifact can have meaningful deterministic checksums that are not zero and zeroing them still keeps autotools happy.

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

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

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