Firebase-tools: Émulateur Firestore en blocage dans la transaction

Plateforme: macOS
Nœud: 10.21.0

Cas de test

Lors de la lecture / écriture d'un document en utilisant deux transactions simultanées, les transactions se bloquent (comme dans un blocage).

J'ai ajouté un exemple de code pour illustrer le problème (y compris des journaux de console pour clarifier où le code se bloque).

firestore-emulator-bug-showcase.zip

Étapes à suivre pour reproduire

Après avoir téléchargé l'exemple de code, exécutez:

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

Pendant que l'émulateur s'exécute, exécutez la commande suivante dans un autre terminal:

npm run test

Comportement prévisible

Je m'attendrais à ce que tous les tests fonctionnent avec succès. Ça signifie:

• le test «firestore» s'exécute avec succès.
• dans le test 'bail single' true est retourné.
• dans le test 'bail multi', une seule des transactions renvoie true tandis que l'autre renvoie false .

Comportement réel

Mais en fait, le test «bail multi» se bloque et expire. Les tests «firestore» et «bail single» s'exécutent comme prévu.

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.
