Abstractions 0.7.1

• IPluginContext.TryRegisterProvider reports a duplicate provider registration instead of hiding it.
• dependencies and extraInfo become empty collections when the manifest contains null.
• The contract documents failed unloads, exact event-type matching, and hooks during self-initiated shutdown.
• This version is MIT on NuGet; 0.7.0 remains LGPL-3.0-or-later.

HostingShim v0.5.1

• Carrier reload keeps the managed core and loaded providers; only child plugins unload and reload (ADR-0037).
• Endstone reload recycles the managed core before the native module unloads, and the log bridge waits for in-flight lines before the old logger is destroyed.
• hostfxr is loaded once per process; repeated reloads no longer accumulate library references.
• The packer understands #:package and recursive #:include with *, **, and ?.
• Manifest and load-path hardening covers null and self dependencies, path-like names, loading-window rollback, and report delivery outside the load lock.
• A manifest that cannot be read is isolated to its package. Explicitly unloading a provider package is refused; changing providers requires restarting the server.
• Smoke tests record the server’s real exit code; Linux links the carrier with -z nodelete.

C# Provider v0.2.1

• Source files can use #:package Id@Version and #:include with globs.
• Cache validation covers both the assembly and its PDB; compilation uses the same source snapshot as the cache key.
• Cache cleanup is safe across processes: old directories need an expired retention window and no active lease; staging and freshly published artifacts are left alone.
• A failed load releases its ALC, and a package must expose exactly one IPlugin type.
• A second provider package for the same plugin type now fails to load instead of remaining idle.

F# Provider v0.1.2

• Compile-time references use the same package-first order as runtime resolution.
• FSharp.Compiler.Service compilation is limited to 30 seconds.
• PDB checksums, the source snapshot, and a unique staging directory protect the cache.
• Entries containing # compile into a new -run-<nonce> directory on every load, so two processes never replace the same cache in place.
• Cross-process cleanup uses retention windows and load leases; a second provider package for the same type fails to load.

RPC Provider v0.2.1

• Parent exit is detected through the process Exited event, so an orphaned plugin shuts down.
• Queues are bounded: 4096 incoming messages, 1024 replies, and 4 MiB per line; overflow reports a fault and stops the child.
• Lines are read in chunks with the 4 MiB limit enforced during reading, before a full line is allocated.
• Notifications are processed in order; during synchronous delivery only requests with an id may reenter, so notifications keep their wire order.
• String request IDs are preserved, structured payloads keep their raw JSON, and a duplicate subscription can upgrade a topic to synchronous delivery.
• A second provider package for the same type fails to load.

Plugin template 0.1.2

• The generated project references Abstractions 0.7.1 with ExcludeAssets="runtime".
• The scaffolding is MIT-0; the contract it references is MIT.

Install

dotnet add package Hosihikari.Abstractions --version 0.7.1
dotnet new install Hosihikari.Plugin.Template::0.1.2

lip install github.com/HosihikariFramework/Shim
lip install github.com/HosihikariFramework/CSharpProvider
lip install github.com/HosihikariFramework/FSharpProvider
lip install github.com/HosihikariFramework/RpcProvider

Shim variants for LeviLamina and Endstone are selected with #levilamina, #endstone, and #endstone_linux; the package without a suffix installs the Linux self-hosted carrier.

Compatibility

Plugins built against Abstractions 0.7.1 use contract api 2 and manifest format_version 1. The previous release line was Abstractions 0.7.0, Shim v0.5.0, Provider v0.2.0 / v0.1.1, and template 0.1.2.
