This interface is getting replaced, so relocating it to the deprecated wrapper package before working on its replacement.

Note: wl_registry_add_listener is undocumented everywhere. Its implementation calls wl_proxy_add_listener which returns 0 on success or -1 on failure.

The sandbox which ldd(1) runs in does not inherit parent work directory, so relative pathnames will not work correctly. While it is trivial to support such a use case, the use of relative pathnames is highly error-prone and generally frowned against in this project. The Exec function remains available under the same signature until v0.4.0 where it will be removed.

This prevents blocking from failures caused by ldd(1) emitting output that is not anticipated by the decoder.

This is mounted for the default read-only /dev/ when programs want to use shm_open(3). Defining it here is less error-prone and saves the extra append at runtime.

This is cleaner and makes more sense. The longer LDFLAGS was never a valid concern since it is always inserted by a script.

These packages are highly specific to hakurei and are difficult to use safely from other pieces of code.
Their exported symbols are made available until v0.4.0 where they will be removed for #24.

This package is ugly and is pending removal only kept alive by xdg-dbus-proxy.

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 writes the 16-byte instance identifier to file descriptor specified by --identifier-fd if set, and closes the file.
This enables safely obtaining the new instance's identifier.

This leaves slots available for additional uid ranges in Rosa OS.
This breaks all existing installations! Users are required to fix ownership manually.

Wanted to do this for a long time, since the key is redundant. This also makes it easier to migrate to the new store interface.

The SharePath is a more stable path than RunDirPath, since it is available all the time and should remain consistent. This also fits better into the intended use case of XDG_RUNTIME_DIR.
Closes#17.

In some cases the signal might be delivered before the signal handler is installed, and synchronising against such a case is too expensive. Instead, use the pipe being closed as a fallback to the regular exit request. This change also moves installation of the signal handler early.

This change also spawns shim before committing system state, leaving it blocking on the setup pipe. The internal/outcome/process structure is also entirely reworked to be much more readable and less error-prone, while enabling basic performance measurements. A long-standing bug where segment lock is not held during Commit is also resolved.
Closes#19.

The handle is otherwise inaccessible without the compat interface. This change also moves compatibility methods to separate adapter structs to avoid inadvertently using them.

This reduces collision with local variable names, and generally makes sense for the new store package, since it no longer specifies the state struct.

The shim does not suspend output to begin with. These are leftovers from when container startup code suspends output.

This fully exposes the store internals for #19 and are final preparations for removing the legacy store interface.
This change also fixes a potential deadlock in the handle initialisation mkdir failure path. This however is never reachable in hakurei as the store is never accessed concurrently.

This replaces the Store interface with something better reflecting the underlying data format for #19. An implementation of Store is provided on top of the new code to ease transition.

This is less error-prone and fits better into internal/app which already uses check.Absolute for all pathnames.

Init is not very talkative after process start even when verbose. Suspending output here is pointless and does more harm than good.

The SIGTERM signal is delivered in many other cases and can lead to strange behaviour. The unconditional resume of the logger also causes strange behaviour in the cancellation forwarding path. This change also passes through additional signals.

This does not yet have full coverage. Test cases covering failsafe paths and error injection will be added eventually.

This helps with other areas of the test suite as they're all based on hst.Template. This also helps contributors understand the behaviour of internal/app as hst.Template covers almost every aspect of it.
