Can't get httpUpdate to work with 832k load

Board: Adafruit feather

Computer OS: Ubuntu 18.04

Description:

I'm trying to use httpUpdate to an Adafruit esp32 feather with an 832k load hosted on an external server, and it isn't working the way I expected it to.

Looking at the code in packages/esp32/hardware/esp32/1.0.1-rc1:
The error happens because ESP.getFreeSketchSpace() is too small. I was expecting that the new ota load would be put into the non-boot partition which has plenty of space (1.3M), and instead I think it is using the boot partition that already has a load in it and only has 456k left to use.

Am I using the ota tool wrong, or do I need to change my system to have a single larger partition instead of two small ones?

partition table

0 - 10 - 10000 - 140000 - app0 - 0
0 - 11 - 150000 - 140000 - app1 - 0
1 - 2 - 9000 - 5000 - nvs - 0
1 - 0 - e000 - 2000 - otadata - 0
1 - 99 - 290000 - 1000 - eeprom - 0
1 - 82 - 291000 - 16f000 - spiffs - 0

Sketch:

#include <Arduino.h>

void setup() {
WiFiClient client;
httpUpdate.update(client, your-path-here)
}

void loop() {
}

You are right, I just fixed it with PR #2161.
