Strange behavior occurs when sending requests at the same time #1292
Description
[REQUIRED] Please fill in the following fields:
- Unity editor version: 2022.1.5
- Firebase Unity SDK version: 9.1.0
- Problematic Firebase Component: Firestore
- Platform you are using the Unity editor on: Windows
- Platform you are targeting: Android
- Scripting Runtime: IL2CPP
[REQUIRED] Please describe the issue here:
If you send 2 requests at the same time: 1 for writing and 1 for reading, then when reading you will receive what was sent for writing, and not what is stored in the database.
If you send 1 read request, then get all the data from the Firestore as usual.
In the Unity editor, concurrent requests are handled correctly.
BUT when compiling for Android, what happens is what is indicated.
Relevant Code:
DocumentReference docRef = db.Collection("users").Document("aturing");
//write 1
Dictionary<string, object> userWriteFirst = new Dictionary<string, object>
{
{ "First", "Alan" },
};
docRef.SetAsync(userWriteFirst).ContinueWithOnMainThread(task => {
Debug.Log("Added data to the aturing document in the users collection.");
});
//read1
docRef.GetSnapshotAsync().ContinueWithOnMainThread(task =>
{
DocumentSnapshot snapshot = task.Result;
if (snapshot.Exists) {
Dictionary<string, object> user = snapshot.ToDictionary();
foreach (KeyValuePair<string, object> pair in city) {
Debug.Log(String.Format("{0}: {1}", pair.Key, pair.Value));
/*
At this point, you expect to see the entire array of data retrieved from the Firebase database,
but you only get this:
> First: Alan
Even if there are dozens of rows in the database
*/
}
});
