Use youki's libcontainer APIs to implement wasmtime shim. #142

Mossaka · 2023-06-13T23:52:09Z

Implement Executor trait for wasmtime executor.
Use libcontainer's lifecycle APIs to implement runwasi's Instance
trait.

TODO

refactor out common functions from both wasmedge and wasmtime shims
figure out how to pass the "test_delete_after_create" test
figure out how to pass the "test_wasi" test
add more tests

Since youki now uses thiserror instead of anyhow, this PR also updates the containerd-shim-wasmedge to properly map the error. Signed-off-by: jiaxiao zhou <[email protected]>

The purpose of this crate is to provide common helper functionalities to shim implementors that use youki's libcontainer crate. Notice that the "containerd-shim-wasm" crate does not depend on libcontainer. This commit refactors shared implementation from the wasmtime and wasmedge shims to the newly created common crate.

This PR is ready to review for now. The test_wasi test is still failing with the following message:

Error: Any(failed to receive. "waiting for init ready". BrokenChannel

Caused by:
    channel connection broken)

Looks great, I am looking with an eye towards how this would work when Windows is added and I think this actually makes a few things easier. The awkward part might be re-using the WasmtimeExecutor directly vs via a youki Container since Windows isn't supported in youki but I think it will work.

+                Ok(_) => 0,
+                Err(e) => {
+                    if e == Errno::ECHILD {
+                        0


I assume this code came from my code, but it has to plant the log in this case.

Could you elaborate more about "plant the log"? Do you want me to log a message when Errno::ECHILD was returned?

when Errno::ECHILD was returned?

Yes 👍

I have added a log messaging saying "no child process" when Errno::ECHILD was returned in both the shims.

I am not entirely sure when people see this log message, that actions they can do to mitigate. Or is this an issue at all in the first place? I would appreciate if anyone can help me to understand it.
