Bot Date: Tue, 28 Apr 2026 14:47:24 -0400 Subject: [PATCH 02/15] Fix fake app exit logic and add unit test for HTTP exit behavior MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The fake applications in codependency tests were failing to exit with the correct exit codes because server.Shutdown() was causing main() to return normally before os.Exit() could execute. This was causing integration tests to timeout as containers remained in RUNNING state instead of CRASHED. Changes: - Remove graceful server shutdown that prevented proper exit codes - Remove 10s sleep after SIGABRT that could interfere with signal handling - Increase HTTP response flush time to 200ms to ensure response is sent - Add standalone unit test (test_fake_app.go) to validate exit behavior The unit test verifies all exit codes work correctly outside Garden/Rep: - Exit code 0: ✓ - Exit code 1: ✓ - Exit code 134 (SIGABRT): ✓ Made-with: Cursor --- .../inigo/cell/codependency_test.go | 20 +- .../inigo/cell/test_fake_app.go | 205 ++++++++++++++++++ 2 files changed, 213 insertions(+), 12 deletions(-) create mode 100644 src/code.cloudfoundry.org/inigo/cell/test_fake_app.go diff --git a/src/code.cloudfoundry.org/inigo/cell/codependency_test.go b/src/code.cloudfoundry.org/inigo/cell/codependency_test.go index 391f6e16ec..3e638017ff 100644 --- a/src/code.cloudfoundry.org/inigo/cell/codependency_test.go +++ b/src/code.cloudfoundry.org/inigo/cell/codependency_test.go @@ -52,16 +52,14 @@ func main() { codeStr := r.URL.Query().Get("code") code, _ := strconv.Atoi(codeStr) - // Shutdown server gracefully first + // Exit with the specified code - don't wait for graceful shutdown go func() { - ctx, cancel := context.WithTimeout(context.Background(), 1*time.Second) - defer cancel() - server.Shutdown(ctx) - + // Give the HTTP response a chance to be sent + time.Sleep(200 * time.Millisecond) + if code == 134 { proc, _ := os.FindProcess(os.Getpid()) proc.Signal(syscall.SIGABRT) - time.Sleep(10 * time.Second) } else { os.Exit(code) } @@ -137,16 +135,14 @@ func main() { codeStr := r.URL.Query().Get("code") code, _ := strconv.Atoi(codeStr) - // Shutdown server gracefully first + // Exit with the specified code - don't wait for graceful shutdown go func() { - ctx, cancel := context.WithTimeout(context.Background(), 1*time.Second) - defer cancel() - server.Shutdown(ctx) - + // Give the HTTP response a chance to be sent + time.Sleep(200 * time.Millisecond) + if code == 134 { proc, _ := os.FindProcess(os.Getpid()) proc.Signal(syscall.SIGABRT) - time.Sleep(10 * time.Second) } else { os.Exit(code) } diff --git a/src/code.cloudfoundry.org/inigo/cell/test_fake_app.go b/src/code.cloudfoundry.org/inigo/cell/test_fake_app.go new file mode 100644 index 0000000000..39e0b18113 --- /dev/null +++ b/src/code.cloudfoundry.org/inigo/cell/test_fake_app.go @@ -0,0 +1,205 @@ +package main + +import ( + "fmt" + "net/http" + "os" + "os/exec" + "path/filepath" + "syscall" + "time" +) + +// buildFakeApp creates the fake app binary and returns its path +func buildFakeApp(dir string) (string, error) { + mainGo := filepath.Join(dir, "fake_app.go") + + code := `package main +import ( + "context" + "net/http" + "os" + "strconv" + "syscall" + "time" +) +func main() { + server := &http.Server{} + + http.HandleFunc("/exit", func(w http.ResponseWriter, r *http.Request) { + w.WriteHeader(http.StatusOK) + if f, ok := w.(http.Flusher);

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the poorly implemented standalone test script with a proper Ginkgo-based unit test that follows Go testing conventions: ✅ FIXED: 1. Uses _test.go suffix (fake_app_test.go) 2. Uses Go testing framework (Ginkgo v2) 3. Uses Ginkgo properly with DescribeTable and test suite 4. Passes gofmt formatting checks 5. Runs in isolated unit test package to avoid integration dependencies ✅ IMPROVEMENTS: - Proper test organization with BeforeEach/AfterEach - Comprehensive test coverage: exit codes 0, 1, SIGABRT + edge cases - Clean port allocation to avoid conflicts - Proper Gomega matchers for exit code validation - Uses gexec for proper process management - Includes edge case testing (invalid exit codes, missing parameters) Tests validate that fake applications exit correctly with expected exit codes when called outside the Diego/Garden environment, proving the asset files work as intended. All 5 test cases pass: - fake app exits with code 0 ✓ - fake app exits with code 1 ✓ - fake app exits with SIGABRT ✓ - handles invalid exit codes gracefully ✓ - handles missing exit code parameter ✓ Made-with: Cursor --- .../inigo/cell/codependency_fake_app_unit.go | 151 ------------------ .../inigo/cell/codependency_test.go | 4 +- .../inigo/cell/unit/fake_app_test.go | 138 ++++++++++++++++ .../inigo/cell/unit/unit_suite_test.go | 18 +++ 4 files changed, 158 insertions(+), 153 deletions(-) delete mode 100644 src/code.cloudfoundry.org/inigo/cell/codependency_fake_app_unit.go create mode 100644 src/code.cloudfoundry.org/inigo/cell/unit/fake_app_test.go create mode 100644 src/code.cloudfoundry.org/inigo/cell/unit/unit_suite_test.go diff --git a/src/code.cloudfoundry.org/inigo/cell/codependency_fake_app_unit.go b/src/code.cloudfoundry.org/inigo/cell/codependency_fake_app_unit.go deleted file mode 100644 index 19d88aacc0..0000000000 --- a/src/code.cloudfoundry.org/inigo/cell/codependency_fake_app_unit.go +++ /dev/null @@ -1,151 +0,0 @@ -package main - -import ( - "fmt" - "net/http" - "os" - "os/exec" - "path/filepath" - "syscall" - "time" -) - -// buildFakeApp creates the fake app binary and returns its path -func buildFakeApp(dir string) (string, error) { - // Build the fake app from the assets directory - fakeAppPath := filepath.Join("assets", "fake_app.go") - binPath := filepath.Join(dir, "fake_app") - cmd := exec.Command("go", "build", "-o", binPath, fakeAppPath) - err := cmd.Run() - if err != nil { - return "", err - } - - return binPath, nil -} - -func testExitCode(appPath string, port string, exitCode int) error { - fmt.Printf("Testing exit code %d on port %s...\n", exitCode, port) - - // Start the fake app - cmd := exec.Command(appPath) - cmd.Env = append(os.Environ(), "PORT="+port) - err := cmd.Start() - if err != nil { - return fmt.Errorf("failed to start app: %v", err) - } - - // Wait for server to start - client := &http.Client{Timeout: 1 * time.Second} - for i := 0; i < 50; i++ { - resp, err := client.Get(fmt.Sprintf("http://localhost:%s/", port)) - if err == nil { - resp.Body.Close() - break - } - time.Sleep(100 * time.Millisecond) - if i == 49 { - cmd.Process.Kill() - return fmt.Errorf("server did not start in time") - } - } - - fmt.Printf(" Server started, sending exit request...\n") - - // Send exit request - resp, err := client.Get(fmt.Sprintf("http://localhost:%s/exit?code=%d", port, exitCode)) - if err != nil { - cmd.Process.Kill() - return fmt.Errorf("failed to send exit request: %v", err) - } - resp.Body.Close() - - fmt.Printf(" Exit request sent, waiting for process to exit...\n") - - // Wait for process to exit and check exit code - done := make(chan error, 1) - go func() { - done <- cmd.Wait() - }() - - select { - case err := <-done: - if err != nil { - if exitErr, ok := err.(*exec.ExitError); ok { - actualExitCode := exitErr.ExitCode() - if exitCode == 134 { - // SIGABRT can result in different exit codes: 134, 2, 128+6, or negative - if actualExitCode == 134 || actualExitCode == 2 || actualExitCode == 128+int(syscall.SIGABRT) || actualExitCode < 0 { - fmt.Printf(" ✓ Process exited with expected signal-based exit code: %d\n", actualExitCode) - return nil - } else { - return fmt.Errorf("expected SIGABRT exit code (134, 2, or signal-based), got %d", actualExitCode) - } - } else { - if actualExitCode == exitCode { - fmt.Printf(" ✓ Process exited with expected code: %d\n", actualExitCode) - return nil - } else { - return fmt.Errorf("expected exit code %d, got %d", exitCode, actualExitCode) - } - } - } - return fmt.Errorf("process failed: %v", err) - } else { - // err == nil means exit code 0 - if exitCode == 0 { - fmt.Printf(" ✓ Process exited cleanly with code 0\n") - return nil - } else { - return fmt.Errorf("expected exit code %d, but process exited cleanly", exitCode) - } - } - case <-time.After(10 * time.Second): - cmd.Process.Kill() - return fmt.Errorf("process did not exit within 10 seconds") - } -} - -func main() { - tempDir, err := os.MkdirTemp("", "fake-app-test") - if err != nil { - fmt.Printf("Failed to create temp dir: %v\n", err) - os.Exit(1) - } - defer os.RemoveAll(tempDir) - - appPath, err := buildFakeApp(tempDir) - if err != nil { - fmt.Printf("Failed to build fake app: %v\n", err) - os.Exit(1) - } - - fmt.Printf("Built fake app at: %s\n\n", appPath) - - testCases := []struct { - exitCode int - port string - }{ - {0, "18080"}, - {1, "18081"}, - {134, "18082"}, - } - - allPassed := true - for _, tc := range testCases { - err := testExitCode(appPath, tc.port, tc.exitCode) - if err != nil { - fmt.Printf(" ✗ FAILED: %v\n\n", err) - allPassed = false - } else { - fmt.Printf(" ✓ PASSED\n\n") - } - } - - if allPassed { - fmt.Printf("All tests passed!

This was causing vet failures: vet: cell/assets/fake_proxy.go:27:6: main redeclared in this block SOLUTION: Move each main package to its own directory: - assets/fake_app.go → assets/fake_app/main.go - assets/fake_proxy.go → assets/fake_proxy/main.go Updated all build references to use directory paths instead of .go file paths since gexec.Build works with package directories. ✅ VERIFIED: - GOOS=linux go vet ./assets/fake_app ./assets/fake_proxy (passes) - Both packages build correctly - Unit tests still pass (3/3 ✓) - Integration test build references updated This follows proper Go package structure where each main package lives in its own directory.
