<!--- Thanks so much for your contribution! If this is your first time contributing, please ensure that you have read the [CONTRIBUTING](https://github.com/pulumi/pulumi/blob/master/CONTRIBUTING.md) documentation. --> # Description <!--- Please include a summary of the change and which issue is fixed. Please also include relevant motivation and context. --> Prompted by having another case in https://github.com/pulumi/pulumi/pull/14548 that looked like "this is just a promise". We already had a mini-promise library for provider config in sdk/go/common/resource/plugin/provider_plugin.go. Plus a couple of places where we did a poor mans Go promise by having a WaitGroup plus a variable to set (see the two changes in /pkg). This adds a little promise library to safely cover all three of these cases plus the case I'll be adding in #14548. It is _minimal_ adding just the features of promises needed for these initial cases. We can add to it as needed. I suspect we've got a number of places in test code that could probably use this as well, but I haven't gone through that. I also suspect that having this type available will result in more places in the future being simpler because "its just a promise" is a fairly common scenario in async systems. In fact Output's internally _are just a promise_ so we could probably rewrite their internals using this, add a `Then()` like method for apply and all the async complexity gets handled in the promise layer while the output layer just cares about unknowns/secrets/etc. ## Checklist - [x] I have run `make tidy` to update any new dependencies - [x] I have run `make lint` to verify my code passes the lint check - [ ] I have formatted my code using `gofumpt` <!--- Please provide details if the checkbox below is to be left unchecked. --> - [x] I have added tests that prove my fix is effective or that my feature works <!--- User-facing changes require a CHANGELOG entry. --> - [ ] I have run `make changelog` and committed the `changelog/pending/<file>` documenting my change - This is in sdk/go/common and I'm considering it an non-public api for now. <!-- If the change(s) in this PR is a modification of an existing call to the Pulumi Cloud, then the service should honor older versions of the CLI where this change would not exist. You must then bump the API version in /pkg/backend/httpstate/client/api.go, as well as add it to the service. --> - [ ] Yes, there are changes in this PR that warrants bumping the Pulumi Cloud API version <!-- @Pulumi employees: If yes, you must submit corresponding changes in the service repo. --> |
