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.

These are too general to belong in the container package. This targets the v0.4 release to reduce the wrapper maintenance burden.

The more explicit API removes the arbitrary limit preventing use of SCHED_OTHER (referred to as SCHED_NORMAL in the kernel). This change also exposes priority value to set.

This side is the read end of a pipe and buffering reads from it ended up performing better than buffering one half of the TeeReader (which already goes through the kernel page cache anyway).

This is not as necessary as it was for nix, since internal/pkg only unblocks exclusive artifacts one at a time. Still, this is useful when running alongside an unprivileged music player which cannot set itself to a higher priority.

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.

No good reason to filter this in the execArtifact container, and the extended filter breaks certain programs.

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

This proxies program output through msg with a name and fd prefix. This also avoids introducing additional information to the container via process stdout/stderr.

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

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.

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.
