calling set() while streaming crashes

[mimming]

Summary

If you call stream() and then attempt to call set() from from another client, the device panics :(

Steps

Run this code

#include <Firebase.h>


Firebase fbase = Firebase("espbutton.firebaseio.com").auth("REDACTED");
Firebase fbaseStream = Firebase("espbutton.firebaseio.com").auth("SAME_VALUE_ALSO_REDACTED");


void setup() {

  Serial.begin(9600);

  Serial.println("Hello world!");  

  // connect to wifi.
  WiFi.begin("OpenWifiNetworkSSID");
  Serial.print("connecting");
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(500);
  }
  Serial.println();
  Serial.print("connected: ");
  Serial.println(WiFi.localIP());

  fbaseStream.stream("/hello");
}

void loop() {
  fbase.set("/", "{\"hello\": \"world\"}");
}

Result

Hello world!
connecting..
connected: 192.168.123.45

Might have a similar crash in #42, will try to repo.

[proppy]

Note this doesn't crash anymore when using https://github.com/esp8266/Arduino master (esp8266/Arduino@5dd6acc).

[BrewCoder]

Is it allowed to stream and push at the same time? (even if using two instances of the firebase client) One of the comments in #41 indicates a push is not intended to work during a stream....

I'm looking for a way to stream configuration data/status from one firebase type while pushing / storing sensor data to a different type. I'm able to run each process independently without issues but the system crashes when pushing data with a stream active.

[proppy]

@BrewCoder does it also crash with https://github.com/esp8266/Arduino master?

[BrewCoder]

@proppy I'm still having the same issue:

Pseudocode:
Firebase fbaseStream = Firebase("**********.firebaseio.com").auth("Token");
Firebase fbasePush = Firebase("**********.firebaseio.com").auth("Token");
FirebaseStream stream;

setup(){
stream = fbaseStream.stream("/controls");

loop(){

Serial.println("streaming error");
Serial.println(stream.error().message());
}
if(stream.available()) {
String event;
auto type = stream.read(event);
Serial.print("event: ");
Serial.println(type);
if (type == FirebaseStream::Event::PUT) {
Serial.print("data: ");
Serial.println(event);
}
}

*****every 30 seconds
FirebasePush push = fbasePush.push("/logs", buffer);
if (push.error()) {
Serial.println("Firebase push failed");
Serial.println(push.error().message());
return;
}
}

[proppy]

I think this is fixed with arduino-esp8266 master (esp8266/Arduino@43fb139).

I was able to run successfully the following sketch:

FirebaseArduino FirebaseStream;

void setup() {
  Serial.begin(9600);

  // connect to wifi.
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  Serial.print("connecting");
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(500);
  }
  Serial.println();
  Serial.print("connected: ");
  Serial.println(WiFi.localIP());

  Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);  
  FirebaseStream.begin(FIREBASE_HOST, FIREBASE_AUTH);
  FirebaseStream.stream("/data");
}

int n = 0;
void loop() {
  Serial.println("loop");
  Firebase.setInt("data", n++);
  if (Firebase.failed()) {
    Serial.println(Firebase.error());
  }
  int data = Firebase.getInt("data");
  if (Firebase.failed()) {
    Serial.println(Firebase.error());
  }
  Serial.print("data: ");
  Serial.println(data);
  Serial.print("heap: ");
  if (FirebaseStream.available()) {
    FirebaseObject event = FirebaseStream.readEvent();
    Serial.print("event: ");
    Serial.println(event.getString("event"));
    Serial.print("path: ");
    Serial.println(event.getString("path"));
    Serial.print("data: ");
    Serial.println(event.getInt("data"));
  }
  Serial.println(ESP.getFreeHeap());
  delay(1000);
}

@BrewCoder can you try again?

[mininao]

I think I have the same issue, with esp8266/arduino pulled straight from master.
Here is the simplest repro I could make : https://gist.github.com/mininao/a3f29eebb39c18c8104ae28e2a74b747
It crashes a few seconds after turning in on, leaving the output that's in the gist

[tabvn]

I confirm that problem still exit , we could not push during stream #185
