How did you test this?
To accept this into TinyGo, I'd like to see at least some tests. For example, you can create a new test like testdata/net.go (and add it to main_test.go for Linux only). It doesn't have to be exhaustive, but for example you can start a socket server (net.Listen) in a goroutine and try to connect to it from the same program.

@aykevl I will add some basic tests. Since I already did some testing (I hope) it should be fairly easy to integrate this here. |

If you put in debugging code, please remove it before sending in a PR. It makes the diff bigger and more work to review.
Generally, take a look at the PR diff and see if there's any part of it that is not necessary and can be removed (such as the changes to .gitmodules and the signal changes that are still part of this PR).
(Also, how do you know that you can just remove this panic?)

if this does not work, do the folliwing steps: 1. remove net submodule 2. remove symlink in local ~/.cache/tinygo/goroot-<hash>/net 3. manual symlink yo local golang /usr/local/bin/src/net Signed-off-by: leongross <[email protected]>

You are working with a copy of the data. This semaphore implementation doesn't actually work.

This is a rework of the plain linux network POC #4460. This PR adds adaptive switching of network packages depending on the
GOOS.The CI fails due to unadjusted build tags for MacOs and WASm.
Successfully tested on
linux/amd64.
