Changes for removing Mapbox Mobile Events and Telemetry

[roblabs]

Analysis of Telemetry and Mapbox Mobile Events using Wireshark to test network traffic on MapLibre.

Summary: Wireshark analysis shows that this Pull Request removes telemetry and eliminates network traffic back to servers such as docs.mapbox.com, events.mapbox.com, api-events-staging.tilestream.net.

Wireshark CLI examples

# Wireshark CLI
brew install wireshark
# Install Wireshark.app with Homebrew Cask:
brew install --cask wireshark
# print list of interfaces and exit
tshark -D
# Capturing on 'Ethernet: en0'
tshark -i en0
# write packets to a pcapng-format file named "outfile"
tshark -i en0 -w outfile.pcapng
# Capture for a duration of 3.5 seconds
tshark -i en0 -w outfile.pcapng -a duration:3.5

Phone home response for MapLibre 5.10.0

2021-02-10 16:03:57.054329-0800 com.roblabs.GeographyClass[67675:1484534] Mapbox Maps SDK for iOS version 6.3.0 is now available: https://github.com/mapbox/mapbox-gl-native-ios/releases/tag/ios-v6.3.0

iOS UserDefaults

If an app that uses MapLibre makes use of UserDefaults, then in MapLibre 5.10.0, the following keys would store persistent data. In MapLibre, these keys would just be stale without any Telemetry home to phone back to.

MGLMapboxMetricsDebugLoggingEnabled = 0
MGLMapboxMetricsEnabled = 1
MGLMapboxAccountType = 0
MGLMapboxMetricsEnabled = 1
MGLMapboxMetricsDebugLoggingEnabled = 0
MGLMapboxAccountType = 0

MapLibre for Android After Removing MME on this Pull Request

After Android commit e14070b

Using the Wireshark filter dns.qry.name contains mapbox || dns.qry.name contains tilestream. No trace of tilestream.net. Tiles are served from Mapbox so a reference to api.mapbox.com is normal.

Using Wireshark on the MapLibre Sample App MapboxGLAndroidSDKTestApp. This is typical DNS queries when fetching tiles from Mapbox, which uses api.mapbox.com as it's tile server.
