feat(vows): improve handling of ephemeral values #9620

0xpatrickdev · 2024-06-30T22:02:33Z

refs: #9308

Description

adds asPromise helper to VowTools for unwrapping Vow|Promise, ensuring proper handling of ephemeral promises
updates watch-utils to better handle values that are not storable durably, such as promises

Testing Considerations

This does not include tests that simulate an upgrade - only a heap zone is used in the included tests. See #9631

Upgrade Considerations

This PR includes changes we'd like to be in the initial release of vows.

packages/vow/src/types.js

+ * @param {Watcher<T, TResult1, TResult2, C>} [watcher]
+ * @param {C} [watcherArgs]
+ * @returns {Promise<TResult1 | TResult2>}
+ */


This is identical to the type for watch, minus the return line. We might consider extracting that logic and extending it, and/or using something like the PromiseToVow helper from @agoric/orchestration that should maybe live here instead:

agoric-sdk/packages/orchestration/src/internal.ts

Lines 3 to 16 in 194ac48

/**

* Converts a function type that returns a Promise to a function type that

* returns a Vow. If the input is not a function returning a Promise, it

* preserves the original type.

*

* @template T - The type to transform

*/

export type PromiseToVow<T> = T extends (

...args: infer Args

) => Promise<infer R>

? (...args: Args) => Vow<R>

: T extends (...args: infer Args) => infer R

? (...args: Args) => R

: T;

Shouldn't lines 14-15 above be removed since they're redundant?

Some F2-practice for you, and just a few minor things. 😉
