- Closes#2078.
- Move all K8s sources from the container-k8s executable
into a new ContainerK8s library target. Sources/Plugins/K8s/
becomes a thin entry point (K8sMain.swift) that calls
K8sCommand.main().
- closes#2043
- introduces the k8s plugin, allowing users to make single
node clusters with the kind base image
- other functionality is included as well such as creation,
deletion, and loading custom images
- When pulling warmup images for concurrent tests, save
the images to a cache directory under the application root.
- Serial tests that aren't testing pull can save time by restoring
a cached warmup image.
Each container runs in its own guest VM sized to
`--memory` with no swap, so the guest kernel's
stock `vm` sysctl defaults are hit far too easily:
- `vm.overcommit_memory=0` (heuristic overcommit)
rejects an oversized `mmap()` upfront whenever the
reservation exceeds the small, swap-less VM's free
RAM — even if the memory is never touched —
returning `ENOMEM`.
- `vm.max_map_count=65530` caps per-process
mapping count, which mapping-heavy applications
(e.g. Elasticsearch, many JVMs) can exceed.
- When container is not running, the runtime helper
traverses the container's root fs and writes it to the
specified tar archive or stdout.
- When the container is running, the helper performs
the same operation but wraps it in freeze/thaw
to ensure data integrity for the resulting archive.
- Closes#2001.
- Handle "container exists" error gracefully instead
of failing, when trying to start the buildkit container.
- Move build tests to parallel suites, while the builder
lifecycle tests remain serial. Parallel builds don't
use the fixture lock that deletes and restarts the
builder and runs a build block in isolation.
- The protobuf makefile relies on being able to find
the built protoc dependencies under the build
directory. Since we were not passing the build
configuration to the swift command to build those
dependencies, the built binaries were going into
the debug build folder. If make protos was run
when `BUILD_CONFIGURATION=release`, then
we'd fail to find the dependencies since the build
folder should now be the release build folder.
This PR fixes that.

Closes https://github.com/apple/container/issues/1687
The default kernel archive is downloaded from a remote release URL
during first-run setup and via `container system kernel set
--recommended`. Previously, the archive contents were not verified after
download, so integrity depended on HTTPS and the release artifact
remaining unchanged.
This change adds digest verification for kernel archives. The
recommended/default kernel now has pinned digest metadata using an
algorithm-prefixed value such as `sha256:<hex>`. `container system
kernel set --tar` accepts `--digest`; remote tar URLs require it, and
local tar archives can also be verified before unpacking and
installation.
The system config also supports `kernel.digest`, and a custom
`kernel.url` must provide a digest for that archive.
- Fixes#1789.
- Release 2.9.0 of `grpc-swift-nio-transport` fixes
an HTTP/2 initialization race where the server could
send SETTINGS before gRPC handlers are added to
the pipeline, causing the client to hang. The new
`WrappedChannel.wrapping(config:serviceConfig:makeChannel:)`
API calls `configure(channel)` inside the channel
initializer, ensuring the pipeline is set up before any inbound
bytes arrive. This eliminates the need for the custom
`HTTP2ConnectBufferingHandler` workaround.
- This fixes the LLVM coverage data not properly being emitted for XPC
services. It requires piping the `LLVM_PROFILE_FILE` environment
variable through to all the services and plugins. The variable itself
also required the "%c" formatter to ensure that it continuously emits
coverage data, otherwise when XPC services are killed via "bootout" they
do not emit coverage.
- Part of #1833.
- CLI progress and registry test migrations were inadventently reverted
by #1857.
- Migrate TestCLINoParallelCases to TestCLIImagePruneSerial and
TestCLINetworkPruneSerial.
- Clean up test selection patterns in Makefile.
- Remove all legacy CLITests files.
- Use swift-testing `withKnownIssue` to run but ignore failures on flaky
`testCreateNameLongestValid` and `testIsolatedNetwork`.
- Extracts a fixture helper for tests requiring a retry loop.
