Bodu.Globalization.Calendar.Plugins

API stability — Stable. The public API surface is committed; breaking changes are reserved for a major-version bump per SemVer.

Trust-gated loading of external Bodu.Globalization.Calendar algorithm plugins. Third-party assemblies can contribute custom INotableDateAlgorithm implementations, but only after passing an explicit trust policy — loading executes attacker-controlled code, so the gate is opt-in and fails closed.

Installation

dotnet add package Bodu.Globalization.Calendar.Plugins

Targets net8.0. All types live in the Bodu.Globalization.Calendar.Plugins namespace.

Trust model

NotableDatePluginLoader evaluates a candidate assembly against an IPluginTrustPolicy before activating any plugin. The policy receives a PluginTrustContext (assembly name, file path, SHA-256 hash, strong-name public-key token) and returns a PluginTrustResult.

Policy Trust basis Guarantee
FileHashPluginTrustPolicy SHA-256 file-hash allow-list Integrity — the exact reviewed bytes, or nothing; the strongest bundled policy
StrongNamePluginTrustPolicy Strong-name public-key token allow-list Identity claim only — .NET (Core) does not verify strong-name signatures at load, and the token is copyable metadata; never sufficient alone for untrusted input — combine with the hash policy
CompositePluginTrustPolicy Every constituent policy (AND) Fails closed; an empty composite trusts nothing
DelegatingPluginTrustPolicy Custom delegate As strong as the delegate
AllowAllPluginTrustPolicy Nothing Development only — accepts everything; unsafe

The gate is an admission check, not a sandbox: an admitted plugin runs with the full trust of the process. The complete contract — entry-point strength, registration collision policy, unloading — is documented in the plugin trust guide.

Plugin contract

A plugin assembly declares its entry point with NotableDatePluginAttribute and implements INotableDateAlgorithmPlugin (deriving from INotableDatePlugin, which carries Name and Version). On load, contributed algorithms are registered into the algorithm registry. Failures surface through a typed exception hierarchy rooted at NotableDatePluginException: PluginNotTrustedException, PluginActivationException, and PluginMissingAttributeException.

Construct a policy (for untrusted input, a CompositePluginTrustPolicy combining the file-hash pin with the strong-name label) and pass it to NotableDatePluginLoader with the plugin's file path; untrusted assemblies are rejected before any plugin type is instantiated. LoadFromFile additionally returns a disposable NotableDatePluginHandle owning the plugin's collectible load context, so the plugin can later be unloaded.
