…ext (#4101) # Description of Changes Makes the `sender` field on `ViewContext` private and exposes a `sender()` method. Does the same for `ReducerContext` and `ProcedureContext`. The purpose of this change: So that the host can determine if/when a view invokes or reads the `sender`. Currently, because `sender` is a field, the host assumes that it is always read. This means views must be materialized per client, even if the view doesn't actually depend on `sender`, resulting in data duplication. The initial solution for this problem was `AnonymousViewContext` which doesn't have a `sender` field. The better solution is to make `sender` a method so that it can call into the host and record when it's actually invoked. Note, this patch only updates the module API, so the current implementation does not change. `ViewContext` views are still duplicated across clients. Changing this requires a new host syscall and for `sender()` to invoke that syscall. This however is backwards compatible and can be done anytime after the module APIs for the other languages (C#, TypeScript, C++) are updated. Also note that `ReducerContext` and `ProcedureContext` were updated purely for consistency. There are currently no plans to track reads of `sender` in these contexts. # API and ABI breaking changes Breaks the rust module api. # Expected complexity level and risk 1 # Testing N/A
# Description of Changes Make `Sender` a method on [Reducer|View|Procedure|Tx]Context in C#. Equivalent changes to #4101. # API and ABI breaking changes API breaking # Expected complexity level and risk 1 # Testing Pure refactor, no additional testing.
# Description of Changes Switch Wasm module to `__describe_module_v10__` from `__describe_module__` to expose `RawModuleDefV10` # API and ABI breaking changes 2.0 breaking change. # Expected complexity level and risk 1 # Testing Exising smoketests should be enough.

There was a problem hiding this comment.
This is a code motion from raw_def/v10.rs to here (in validation) to re-use logic across Rust, Typescript modules.
