WASM bugs with `--closed-world`: "publicly exposed type disallowed"

[sgammon]

Describe the bug When trying to build the WASM samples on macOS, the new --closed-world flag is causing some issues. At first, I needed to build binaryen from trunk to get access to the --closed-world flag at all. Then, after building from trunk, I get the errors listed below.

To Reproduce No snippet needed, just building the WASM sample

Bazel version Please include version of Bazel that you are running J2CL with: $ bazel version

Bazelisk version: v1.11.0
Build label: 5.2.0
Build target: bazel-out/darwin_arm64-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar
Build time: Tue Jun 7 16:11:09 2022 (1654618269)
Build timestamp: 1654618269
Build timestamp as int: 1654618269

Expected behavior I expected it to build

[sgammon]

after switching to the PR tagged in this issue, and removing only the --closed-world flag, the WASM sample built for me. adding the flag back fails the build again. maybe i need some additional flag to cover these publics? thank you J2CL team for considering this issue.

[sgammon]

another bug building the WASM sample, but this time building the JS app:

console is defined in the externs for the closure compiler. It might be a configuration or version issue, not sure. But our wasm backend is in flux and sometimes it needs very specific versions of Chrome and binaryen.

It is a bit rough on the edges and we haven't focused yet on making the opensource version seamless.

oh, i should have noticed this was console related @rluble, i am building with --env=CUSTOM for a pure-JS environment. passing a blanket suppression got me working for now. it would help if the j2wasm_* rules allowed kwargs which they pass to the underlying closure calls; i've made such a change on my branch and can offer it as a PR if the team is interested.

thank you for getting back to me

[sgammon]

also, maybe it would be helpful if i wrote some rules that install the right Binaryen bins? any interest there too, if i set that up? thanks again

[sgammon]

(i should also say, make sure to expand the error in the bug, the JS one above may be console related, but I'm not sure the main one is)

[gkdn]

It looks like you hit some in between versions, pls for now use an earlier version of binaryen. (I will keep this issue open though to ensure the problem will be fixed in open source as well).

j2wasm_application rule, the way imports work etc. will through some overhaul. We can discuss again in couple of months and looks for potential improvements there.

Yes, that would be cool (though it may require some active maintenance if you would like to bite bullet)

[sgammon]

@gkdn if memory serves i had to use a latest version of binaryen to support --closed-world, but adding the ability to pass parameters and dropping the invalid ones lets me use the latest release. we're thinking of using J2CL and J2WASM again for a new project and if we do, we'd be happy to write some quick binaryen rules.

[gkdn]

I think all the closed-world issues are fixed. Closing this for now, let me know if not.

[sgammon]

@gkdn thank you again!
