fitzgen requested wasmtime-core-reviewers for a review on PR #6789.
fitzgen opened PR #6789 from fitzgen:resources-required
to bytecodealliance:main
:
Returns a summary of the resources required to instantiate this module or component.
Potential uses of the returned information:
Determining whether your pooling allocator configuration supports instantiating this module.
Deciding how many of which
Module
you want to instantiate within a fixed amount of resources, e.g. determining whether to create 5 instances of module X or 10 instances of module Y.Part of #6627.

I expect that this means, for all components using the wasi-preview1-component-adapter (which, for now, is approximately all "real world" components), we won't be able to use this estimator. How much effort would it be to detect and handle the simplest cases of modules importing a memory?
fitzgen submitted PR review.
fitzgen created PR review comment:
If the adapter is still part of this component graph, then everything should be fine and this method will work today as-is.
If the adapter is a module that the component graph imports from the host, then there really isn't much we can do here. An imported module could define zero or five memories, we have no way of telling how many it will need without actually having the module.

got it! thanks. I misunderstood the way in which
Import
was being used here.

Ah, yeah this is after the component graph has been collapsed/inlined into a single thing, so imports at this layer are imports into the component graph, not between modules within the same component graph.
