Thanks @mobizt .It's works well after latest update.
But here i facing some problem. At few days i try my prior Firebase Stream code. It's got the exception and the exception is will caused randomly.
In my code i use two FirebaseData object and a FirebaseJson object. An FirebaseData object which i called fbdo1 is used to streaming and the streaming data will stored to the FirebaseJson object. Another FirebaseData object i called fbdo2 is used to get and post data to database.
At the setup, i used both FirebaseData objects to write some data to database, but after the loop, i only use fbdo1 to receive streaming data and fbdo2 use to write and recieve.
But let me confused is, the code will be crashed at sometime. So l try to deploy the code in two different environment. The first environment(env1) which wifi signal is strong, and another environment(env2) which signal is very weak, may connection lost or recieve data slowly(maybe is the main problem). At the env1, the code is works well, and now i'm deploying it. But the env2, it may caused wdt reset at sometime. And it's amazing is, the caused exception code is not the same, maybe caused exception29, exception9, or another situation.
So i used espExceptionDecoder to decode it, and it get the follows error. I'm guessing it may caused by the environmentwhich due to the WIFI signal is weak, so when it handle request, it can't completely receive, or get the mistake.

Here is my first exception code:

Exception (9):

The first decoded error is you don't have enough memory for SSL handshaking.
The second decoded error is you don't have enough memory for making the http request header string.

Both errors occurred when you call getJSON.

You free memory is not enough for making a request.

from firebase-esp-client.

Okay. I test my code in last two days. If i only use streaming to a RTDB node(call node1), the code seems works well, and same test result to only receive another node(call node2) periodically, but wdt reset will triggerd if use streaming to node1 and receive node2 periodically.

I also use the esp8266 api to get free heap size(system_get_free_heap_size()), and i observe that if it receive data successfully, system_get_free_heap_size() will return almost 20500 bytes, then if it receive data failed, and the FirebaseData.errorReason() return "not connect", system_get_free_heap_size() will return about 15000 bytes, or lower it. Contrary, if the FirebaseData.errorReason() return connection lost, the return value will higher than successfull situation(about 27000 bytes).

In my whole code i clear the FirebaseData object everytime i received data(only clear the receive FirebaseData object, the streaming FirebaseData object will not do this), and cleared FirebaseJson object, and deconstructor the FirebaseJsonData object at the end of the function if i used them.

Could i effectively reduce used heap size by doing this? Or is it unnecessary?

from firebase-esp-client.

The free memory required for SSL client operation especially in handshaking and will not free until the connection was closed. The SSL handshaking may fail when no enough memory.

Call the member function clear from Firebase Data object also stop the SSL client and release the resources.

Call the member function clear from FirebaseJson will clear the internal dynamic allocation memory but some are not freed until the object goes out side the scope. The FirebaseJsonData class doesn't have the clear function.

The memory also reserved by internal SSL client for buffering with function setBSSLBufferSize of the Firebase Data object.

The stream Firebase Data object should be defined as global while Firebase Data object and FirebaseJson object can define as local var.

You should test everything and manage your own usages which I can't recommend or give the solution based on your situation.

from firebase-esp-client.

Okay. I will continue to test. Thanks for your clearly explanation, i will post the main problem here if i found it.

from firebase-esp-client.

Hello @mobizt, in this few days i try several experiment with my code and example code.
In my code i try to

1. only stream to a parent node (which have 5 children node)
2. stream to parent node and get other children node (called node2, which have 12 children nodes)
3. only get children node (node2)

Then the test result still crashed at sometimes, and before the code crashed, the output will occur that like not connected or read Timeout.
So after this, i also test the example .

In example code i also got crashes at some time, but before the crashes, it seems like have the same situation with my code.
In my guess the crashes may be caused by poor WIFI signal, which caused the memory unable to release normally.
Here is the example code's whole of output and exception:
opt1.txt
exception decoder output.txt

from firebase-esp-client.

If you want to get the actual stream event data payload, in this case for testing, don't use multiPathStream which do post processing the data and can be failed in truncated, incomplete JSON, use normal stream functions.

You need to provide more SSL tx buffer (BearSSL) and response size for JSON payload (see the setup in examples).

The crash can be in the id token exchange and refreshment process which required time and resources to handle the token.

If you want stable operation but less secure at this time, use the legacy token (database secret).
