Firebase-tools: محاكي Firestore في حالة توقف تام في المعاملة

لا تحذف Validate_template = true template_path = .github / ISSUE_TEMPLATE / bug_report.md

معلومات البيئة

أدوات Firebase
النظام الأساسي: macOS
العقدة: 10.21.0

حالة اختبار

عند القراءة / الكتابة إلى مستند باستخدام معاملتين متزامنتين ، تتوقف المعاملات (كما لو كانت في طريق مسدود).

لقد أضفت بعض التعليمات البرمجية لتوضيح المشكلة (بما في ذلك بعض سجلات وحدة التحكم لتوضيح مكان تعليق الرمز).

firestore-emulator-bug-showcase.zip

خطوات التكاثر

بعد تنزيل نموذج التعليمات البرمجية ، قم بتشغيل:

npm install
firebase emulators:start --only firestore --debug # Assuming to be at version 8.5.0

أثناء تشغيل المحاكي ، قم بتشغيل الأمر التالي في محطة مختلفة:

npm run test

سلوك متوقع

أتوقع تشغيل جميع الاختبارات بنجاح. هذا يعنى:

• يتم تشغيل اختبار "firestore" بنجاح.
• في اختبار "التأجير الفردي" يتم إرجاع true .
• في اختبار "lease multi" ، تُرجع إحدى المعاملات true بينما تُرجع المعاملة الأخرى false .

السلوك الفعلي

ولكن في الواقع ، فإن اختبار "عقد الإيجار المتعدد" معلق وينتهي المهلة. يعمل الاختباران "firestore" و "lease single" كما هو متوقع.

انظر الإخراج أدناه:

A worker process has failed to exit gracefully and has been force exited. This is likely caused by tests leaking due to improper teardown. Try running with --runInBand --detectOpenHandles to find leaks.
