Unused imports:** Added `strings` import only where used for validation. \ No newline at end of file diff --git a/src/code.cloudfoundry.org/executor b/src/code.cloudfoundry.org/executor index 8eaf4cb397..b928c85375 160000 --- a/src/code.cloudfoundry.org/executor +++ b/src/code.cloudfoundry.org/executor @@ -1 +1 @@ -Subproject commit 8eaf4cb3970e39c5fce9c50ec933bfd549ecfb67 +Subproject commit b928c8537549aaa7786d1b2af30a84f7b85a8fb1 diff --git a/src/code.cloudfoundry.org/inigo/bin/test.bash b/src/code.cloudfoundry.org/inigo/bin/test.bash index b0fabb0975..dcaa47c88c 100755 --- a/src/code.cloudfoundry.org/inigo/bin/test.bash +++ b/src/code.cloudfoundry.org/inigo/bin/test.bash @@ -188,4 +188,4 @@ filesystem_create_loop_devices 256 # Double-quoting array expansion here causes ginkgo to fail echo "Log Dir: /tmp/inigo-logs" mkdir /tmp/inigo-logs -go run github.com/onsi/ginkgo/v2/ginkgo ${@} --output-dir /tmp/inigo-logs --json-report report.json +go run github.com/onsi/ginkgo/v2/ginkgo ${@} --output-dir /tmp/inigo-logs --json-report report.json cell diff --git a/src/code.cloudfoundry.org/inigo/cell/assets/fake_app/main.go b/src/code.cloudfoundry.org/inigo/cell/assets/fake_app/main.go new file mode 100644 index 0000000000..196bfc9fb0 --- /dev/null +++ b/src/code.cloudfoundry.org/inigo/cell/assets/fake_app/main.go @@ -0,0 +1,83 @@ +package main + +import ( + "fmt" + "net/http" + "os" + "strconv" + "syscall" + "time" +) + +func logToFile(msg string) { + // Log to both stdout (for Garden capture) and a file (as backup) + fmt.Println(msg) + + // Also write to /tmp as backup + f, err := os.OpenFile("/tmp/fake-app-debug.log", os.O_APPEND|os.O_CREATE|os.O_WRONLY, 0644) + if err != nil { + return + } + defer f.Close() + + f.WriteString(msg + "\n") +} + +func main() { + port := os.Getenv("PORT") + if port == "" { + port = "8080" + } + + // Write a startup marker immediately + startupMsg := fmt.Sprintf("FAKE_APP_DEBUG: %s Starting fake app on port %s, pid=%d", time.Now().Format(time.RFC3339Nano), port, os.Getpid()) + logToFile(startupMsg) + + // Also create a simple marker file to prove we ran + os.WriteFile(fmt.Sprintf("/tmp/fake-app-started-%s", port), []byte(startupMsg), 0644) + + server := &http.Server{} + + http.HandleFunc("/exit", func(w http.ResponseWriter, r *http.Request) { + codeStr := r.URL.Query().Get("code") + code, _ := strconv.Atoi(codeStr) + port := os.Getenv("PORT") + if port == "" { + port = "8080" + } + + logToFile(fmt.Sprintf("FAKE_APP_DEBUG: %s Received exit request, code=%d, port=%s, pid=%d", time.Now().Format(time.RFC3339Nano), code, port, os.Getpid())) + + w.WriteHeader(http.StatusOK) + if f, ok := w.(http.Flusher);
