# Description
`FileCopy` silently swallows file not found errors which leads to hard
to debug issues. For instance, as described in #14694, tests with edit
steps unexpectedly run twice against the first step.
Fixes#14694Fixes#5230
Merging this will break plenty of existing tests if they're not fixed
first. [This
query](https://github.com/search?q=org%3Apulumi+path%3A_test.go+%2F%5E%5Ct*Dir%3A+*%22%2F&type=code)
is a rough indication.

Support returning plain values from methods.
Implements Node, Python and Go support.
Remaining:
- [x] test receiving unknowns
- [x] acceptance tests written and passing locally for Node, Python, Go
clients against a Go server
- [x] acceptance tests passing in CI
- [x] tickets filed for remaining languages
- [x] https://github.com/pulumi/pulumi-yaml/issues/499
- [x] https://github.com/pulumi/pulumi-java/issues/1193
- [x] https://github.com/pulumi/pulumi-dotnet/issues/170
Known limitations:
- this is technically a breaking change in case there is code out there
that already uses methods that return Plain: true
- struct-wrapping limitation: the provider for the component resource
needs to still wrap the plain-returning Method response with a 1-arg
struct; by convention the field is named "res", and this is how it
travels through the plumbing
- resources cannot return plain values yet
- the provider for the component resource cannot have unknown
configuration, if it does, the methods will not be called
- Per Luke https://github.com/pulumi/pulumi/issues/11520 this might not
be supported/realizable yet

Per team discussion, switching to gofumpt.
[gofumpt][1] is an alternative, stricter alternative to gofmt.
It addresses other stylistic concerns that gofmt doesn't yet cover.
[1]: https://github.com/mvdan/gofumpt
See the full list of [Added rules][2], but it includes:
- Dropping empty lines around function bodies
- Dropping unnecessary variable grouping when there's only one variable
- Ensuring an empty line between multi-line functions
- simplification (`-s` in gofmt) is always enabled
- Ensuring multi-line function signatures end with
`) {` on a separate line.
[2]: https://github.com/mvdan/gofumpt#Added-rules
gofumpt is stricter, but there's no lock-in.
All gofumpt output is valid gofmt output,
so if we decide we don't like it, it's easy to switch back
without any code changes.
gofumpt support is built into the tooling we use for development
so this won't change development workflows.
- golangci-lint includes a gofumpt check (enabled in this PR)
- gopls, the LSP for Go, includes a gofumpt option
(see [installation instrutions][3])
[3]: https://github.com/mvdan/gofumpt#installation
This change was generated by running:
```bash
gofumpt -w $(rg --files -g '*.go' | rg -v testdata | rg -v compilation_error)
```
The following files were manually tweaked afterwards:
- pkg/cmd/pulumi/stack_change_secrets_provider.go:
one of the lines overflowed and had comments in an inconvenient place
- pkg/cmd/pulumi/destroy.go:
`var x T = y` where `T` wasn't necessary
- pkg/cmd/pulumi/policy_new.go:
long line because of error message
- pkg/backend/snapshot_test.go:
long line trying to assign three variables in the same assignment
I have included mention of gofumpt in the CONTRIBUTING.md.
After internal discussion, we determined "smoke" is a misleading
adjective for this category of tests. What we called "smoke tests"
are short integration tests for basic cross-platform functionality.
As a result, these are better named "acceptance" tests, since smoke
tests are intended to be a low water mark at the unit level to sniff
out bigger issues with the build as a whole.
