This is a more reliable form of pathname to self and also cheaper than os.Executable.

These are not fully controlled by hakurei and may change depending on host configuration.

This discontinues use of the deprecated ldd.Exec function for #25.

This requires cgo so unfortunately will not run in the playground.

While fd created from this side always has the FD_CLOEXEC flag, the same is not true for files left open by the parent. This change prevents those files from leaking into the container.

This closes them during the adopt wait delay. This also keeps them alive.

Seccomp lookup tables are going to be relocated here, and PNR constants.

Should have done this when relocating this from container. Now is a good time to rename it before v0.3.x.

This package will also hold syscall lookup tables for seccomp.

This should eliminate intermittent failures in the forward test.

Most tests already had no global state, however parallel was never enabled. This change enables it for all applicable tests.

This package is quite useful. This change allows it to be imported without importing container.

This keeps composites analysis happy without making the test cases (too) bloated.

This makes handling of fatal errors a lot less squirmy.

This helps indicate the exact origin and nature of the error. This eliminates generic WrapErr from container.

With the new instrumentation it is now possible to run init code outside integration tests.

The container test suite has always been somewhat inadequate due to the inability of coverage tooling to reach into containers. This has become an excuse for not testing non-container code as well, which lead to the general lack of confidence when working with container code. This change aims to be one of many to address that to some extent.

This is simultaneously more efficient and less error-prone. This change caused minor API changes in multiple other packages.

This is way higher level than the container package and does not even work unless every path is mounted in the exact same location.
This behaviour causes nothing but confusion and problems,

There are significant limitations to using the overlay mount, and the implementation in the kernel is quite quirky. For now the Op is quite robust, however a higher level interface for it has not been decided yet.

This further reduces noise on test failure by only passing through output of the failed test.

There is usually no good reason to write to /dev. This however doesn't work in internal/app because FilesystemConfig supplied by ContainerConfig might add entries to /dev, so internal/app follows DevWritable with Remount instead.

There is no reason to mount mqueue anywhere else, and these Ops usually follow each other. This change merges them. This helps decrease IPC overhead and also enables mounting dev readonly.

This is useful for building a filesystem hierarchy then remounting it readonly.

This is more elegant and allows for much easier extension of the tests. Mountinfo is still serialised however due to libPaths nondeterminism.

This part of the interface is very unintuitive and only used for testing, even in testing it is inelegant and can be done better.

This allows slightly easier use of the vanity url. This also provides some disambiguation between low level containers and hakurei app containers.
