@nikpivkin as you mentioned, I removed the packages that exist in defsec today so we can properly make another PR to bring them into Trivy later.

@DmitriyLewen the errors in the CI seem unrelated to this PR. Is it because we have to update tinygo version after the bump to Go 1.21?

Hello @simar7
We have not received this error before.

I tried to reproduce your error locally, but tests for your PR work correctly:

➜  trivy git:(merge-trivy-iac-2) ✗ tinygo version
tinygo version 0.29.0 darwin/amd64 (using go version go1.21.4 and LLVM version 15.0.0)

➜  trivy git:(merge-trivy-iac-2) ✗ mage test:module   
...
=== RUN   TestModule
=== RUN   TestModule/spring4shell_jre_8,_severity_update
=== RUN   TestModule/spring4shell_jre_11,_no_severity_update
--- PASS: TestModule (6.04s)
    --- PASS: TestModule/spring4shell_jre_8,_severity_update (2.68s)
    --- PASS: TestModule/spring4shell_jre_11,_no_severity_update (3.20s)
PASS
ok      github.com/aquasecurity/trivy/integration       7.578s

I also pulled changes (bump to 1.21) to my PR - #5630.
Tests are successful.

I see you update/add some dependencies.
Perhaps there is a conflict?

I see - it's strange indeed. I will try to rebase and see what happens. Thanks for looking into it.

I found the following in the tinygo documentation on the supported packages page:

os/user
The compiler gave the following error when this package was imported:
# os/user
../../../../../../usr/local/go1.20/src/os/user/cgo_lookup_cgo.go:14:6: not implemented: build constraints in #cgo line

But I used go mod graph and couldn't find a package that used that.

Also I get the following error if I disable CGO (which does not happen in main):

CGO_ENABLED=0 go generate pkg/module/testdata/analyzer/analyzer.go
# golang.org/x/sys/unix
../../../../../../go/pkg/mod/golang.org/x/[email protected]/unix/syscall_linux.go:1893:64: undefined: syscall.Rlimit

Interesting find, but we don't use cgo in Trivy or is it a dependency of Trivy that does so (maybe tinygo?) we might have to look through the diff of the changed dependencies here
What do the entries on that page imply? Are they just outputs of tinygo running against certain code?

But I used go mod graph and couldn't find a package that used that.

Also I get the following error if I disable CGO (which does not happen in main):

CGO_ENABLED=0 go generate pkg/module/testdata/analyzer/analyzer.go

Hmm.. I'm also not sure. So far I've tried the following with no success:

1. Downgrade Trivy version to 1.20
2. Upgrade tinygo to v0.30.0
3. Disabling CGO intentionally by passing in CGO_ENABLED=0 as an argument to the mage module test. Using sh.RunWith() here I got this idea from here

I'm not able to reproduce this issue locally either. I am clearing go test cache between tests via go clean -testcache.

@simar7 I tried re-migrating trivy-iac and locally all my tests passed. CI failed due to linter issues.

Interesting does that mean it's just the GitHub Actions not working well on this PR? Or are there any differences between your PR and this?

[nikpivkin]

@simar7 I compared go.mod and didn't seem to notice any difference.

Closing in favor of #5692 as this one has something up with the CI actions.
