The error `runtime: checkdead: find g 19 in status 1` occurred when run go test #32

Closed 201907 closed 9 months ago

201907 commented 10 months ago

Describe the bug

When running “go test” on multiple test files in different packages concurrently, deadlock may occur in windows system.

To Reproduce

Steps to reproduce the behavior:

  1. Create a folder “test1” with files: “main_test.go". 
    
import (
"fmt"
"testing"
"time"
. "github.com/bytedance/mockey"
. "github.com/smartystreets/goconvey/convey"
)

func Foo(in string) string { return in }

type A struct{}

func (a A) Foo(in string) string { return in }

var Bar = 0

func TestMockXXX(t testing.T) { PatchConvey("TestMockXXX", t, func() { Mock(Foo).Return("c").Build() // mock function Mock(A.Foo).Return("c").Build() // mock method MockValue(&Bar).To(1) // mock variable time.Sleep(5 time.Second) So(Foo("a"), ShouldEqual, "c") // assert Foo is mocked So(new(A).Foo("b"), ShouldEqual, "c") // assert A.Foo is mocked So(Bar, ShouldEqual, 1) // assert Bar is mocked }) // mock is released automatically outside PatchConvey fmt.Println(Foo("a")) // a fmt.Println(new(A).Foo("b")) // b fmt.Println(Bar) // 0 }


2. Copy the test1 folder 15 times.
3. CD to the parent folder of “test1” and execute the following command: `go test -gcflags="all=-l -N" -p 1 -v -cover -covermode count -coverprofile cover.out ./...`
4. The error `runtime: checkdead: find g 19 in status 1` occurred.

**Mockey version:**

github.com/bytedance/mockey v1.2.4

**Environment:**

set GOVERSION=go1.20.1

Describe the bug

When running “go test” on multiple test files in different packages concurrently, deadlock may occur in windows system.

To Reproduce

Steps to reproduce the behavior:

  1. Create a folder “test1” with files: “main_test.go".
import (
  "fmt"
  "testing"
  "time"
  . "github.com/bytedance/mockey"
  . "github.com/smartystreets/goconvey/convey"
)

func Foo(in string) string {
  return in
}

type A struct{}

func (a A) Foo(in string) string { return in }

var Bar = 0

func TestMockXXX(t *testing.T) {
  PatchConvey("TestMockXXX", t, func() {
      Mock(Foo).Return("c").Build()   // mock function
      Mock(A.Foo).Return("c").Build() // mock method
      MockValue(&Bar).To(1)           // mock variable
      time.Sleep(5 * time.Second)
      So(Foo("a"), ShouldEqual, "c")        // assert `Foo` is mocked
      So(new(A).Foo("b"), ShouldEqual, "c") // assert `A.Foo` is mocked
      So(Bar, ShouldEqual, 1)               // assert `Bar` is mocked
  })
  // mock is released automatically outside `PatchConvey`
  fmt.Println(Foo("a"))        // a
  fmt.Println(new(A).Foo("b")) // b
  fmt.Println(Bar)             // 0
}
  1. Copy the test1 folder 15 times.
  2. CD to the parent folder of “test1” and execute the following command: go test -gcflags="all=-l -N" -p 1 -v -cover -covermode count -coverprofile cover.out ./...
  3. The error runtime: checkdead: find g 19 in status 1 occurred.

Mockey version:

github.com/bytedance/mockey v1.2.4

Environment:

set GOVERSION=go1.20.1 set GCCGO=gccgo set GOAMD64=v1

Mockey does not support parallel testing. But it Looks weird. Since you added -p 1 and didn't use t.Parallel()， your packages will not meet the concurrecy problem because your tests ran one by one. Are you sure you ran different package tests concurrently ?

I'm sorry I misspoke. I want different package test cases to be executed without concurrency so I added the argument -p 1.

runtime: checkdead: find g 19 in status 1

This error sometimes occurs and sometimes does not occur. There are also cases where all tests are successful. And when an error occurs, the test case often stalls for about ten minutes.

We have tried on win+go1.20 many times with more cases but it never occurs. Closed for there is no more infomations and currently we can't reproduce it. Reopen If anyone else meet the same issue.
