This was an oversight in 9fdb6e6. Fixing this is necessary to make `executionAsyncResource()` work as expected.

Adding AsyncLocalStorage class to async_hooks module. This API provide a simple CLS-like set of features. Co-authored-by: Andrey Pechkurov <apechkurov@gmail.com> PR-URL: nodejs#26540 Reviewed-By: Matteo Collina <matteo.collina@gmail.com> Reviewed-By: Stephen Belanger <admin@stephenbelanger.com> Reviewed-By: Gireesh Punathil <gpunathi@in.ibm.com> Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Michaël Zasso <targos@protonmail.com>
This commit introduces store as the first argument in AsyncLocalStorage's run methods. The change is motivated by the following expectation: most users are going to use a custom object as the store and an extra Map created by the previous implementation is an overhead for their use case. Important note. This is a backwards incompatible change. It was discussed and agreed an incompatible change is ok since the API is still experimental and the modified methods were only added within the last week so usage will be minimal to none.

This allows transitioning the entire following sync and async execution sub-tree to the given async storage context. With this one can be sure the context binding will remain for any following sync activity and all descending async execution whereas the `run*(...)` methods must wrap everything that is intended to exist within the context. This is helpful for scenarios such as prepending a `'connection'` event to an http server which binds everything that occurs within each request to the given context. This is helpful for APMs to minimize the need for patching and especially adding closures.

@puzpuzpuz thank you for maintaining the PR. The next v12.x release will be semver-patch so we can't merge this yet. |
@targos Thanks for the heads-up. 👍 No problem with that. I'm just trying to keep an eye on this backport and keep it in up-to-date state. |
