Board manager mixes up packages from different sources

[emontnemery]

With the following settings:

"arduino.additionalUrls": "https://raw.githubusercontent.com/sparkfun/Arduino_Boards/master/IDE_Board_Manager/package_sparkfun_index.json,
                           http://arduino.esp8266.com/stable/package_esp8266com_index.json"

Board manager mixes up / merges the ESP8266 packages from esp8266.com and sparkfun.
What is shown in board manager is a merged list of supported boards, and version number from esp8266.com package:

SparkFun ESP8266 Boards by SparkFun Electronics
Boards included in this package:
SparkFun Blynk Board - ESP8266, SparkFun ESP8266 Thing, SparkFun ESP8266 Thing - Development Board, 
Generic ESP8266 Module, Olimex MOD-WIFI-ESP8266(-DEV), NodeMCU 0.9 (ESP-12 Module), NodeMCU 1.0 (ESP-12E Module), 
Adafruit HUZZAH ESP8266 (ESP-12), ESPresso Lite 1.0, ESPresso Lite 2.0, Phoenix 1.0, Phoenix 2.0, SparkFun Thing, 
SweetPea ESP-210, WeMos D1, WeMos D1 mini, ESPino (ESP-12 Module), ESPino (WROOM-02 Module), WifInfo, ESPDuino

This is design by Arduino IDE behavior
Repro steps:

1. only add "Additional Boards Manager URLs" value : thttps://raw.githubusercontent.com/sparkfun/Arduino_Boards/master/IDE_Board_Manager/package_sparkfun_index.json
   then select SparkFun in Boards Manager, you can see 'SparkFun ESP8266 Boards by SparkFun Electronics'
   

2. Re-set "Additional Boards Manager URLs" value :
   https://raw.githubusercontent.com/sparkfun/Arduino_Boards/master/IDE_Board_Manager/package_sparkfun_index.json
   http://arduino.esp8266.com/stable/package_esp8266com_index.json

Select SparkFun again in Boards Manager, you can not see 'SparkFun ESP8266 Boards by SparkFun Electronics', only find "esp8266".

@ArthurMa1978 ,This is design by Arduino IDE behavior, can we close it?

[emontnemery]

@czgtest The issue/bug you have reproduced in Arduino IDE is not same as I reported, please don't close this issue.
Issue in Arduino IDE

• Only one board package with same name allowed

Issue reported in VS Code plugin

• Two packages with same name are merged

[czgtest]

@Sneezry can you help to investigate it?

[Sneezry]

@emontnemery If I understand correctly, we should just ignore one board with the same name, but not merge them, right?

[emontnemery]

You should for sure not merge them.
Only displaying one, just like Arduino IDE is doing, is OK I guess.
A nicer solution might be to display both in the board manager, but only allow installing one at the same time.

[Sneezry]

@emontnemery OK, thanks for figuring it out.

[czgtest]

@Sneezry I can't see any change, the result is the same as before.
