Firebase-tools: लेन-देन में गतिरोध में फायरस्टार एमुलेटर

DELETE को मान्य नहीं करें_लेट करें = true template_path = .github / ISSUE_TEMPLATE / bug_report.md

पर्यावरण की जानकारी

फायरबेस -टूल्स: 8.5.0
प्लेटफ़ॉर्म: macOS
नोड: 10.21.0

परीक्षण का मामला

जब एक साथ दो लेन-देन का उपयोग करते हुए दस्तावेज़ को पढ़ना / लिखना, लेनदेन लटका (जैसे कि एक गतिरोध में)।

मैंने समस्या का वर्णन करने के लिए कुछ नमूना कोड जोड़े (कोड को लटकाए जाने को स्पष्ट करने के लिए कुछ कंसोल लॉग सहित)।

firestore-emulator-bug-showcase.zip

प्रजनन करने कि प्रक्रिया

नमूना कोड चलाने के डाउनलोड करने के बाद:

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

जबकि एमुलेटर चलता है, एक अलग टर्मिनल में निम्न कमांड चलाएँ:

npm run test

अपेक्षित् व्यवहार

मैं सभी परीक्षणों को सफलतापूर्वक चलाने की उम्मीद करूंगा। इसका मतलब है की:

• 'फायरस्टार' परीक्षण सफलतापूर्वक चलता है।
• 'लीज सिंगल' टेस्ट में true लौटा है।
• 'लीज मल्टी' टेस्ट में केवल एक लेन-देन true लौटता है जबकि दूसरा false ।

वास्तविक व्यवहार

लेकिन वास्तव में 'लीज मल्टी' टेस्ट लटका हुआ है और बार-बार निकलता है। 'फायरस्टार' और 'लीज सिंगल' परीक्षण उम्मीद के मुताबिक चलते हैं।

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.
