Maintenance

Dependencies

• Upgrade inet.af/netaddr to 2021-07-18

CI

• Remove microbadger hook from CI
• Rename .github/workflows/build.yml to .github/workflows/ci.yml for linting
• Bump docker/build-push-action from 2.4.0 to 2.6.1
• Use curly braces around BUILDPLATFORM
• Rename BUILD_DATE to CREATED
• Build all images fully in parallel (thanks to JSON server information using less memory at compile time)

Code

• Hardcoded servers data as a JSON embedded file in internal/constants/servers.json
  • use embed.FS to have immutable data
  • use sync.Once to parse JSON data only once without data races
• Remove debug line in health server
• Improve health code
• Use qdm12/gosplash for initial logs
• Upgrade qdm12/golibs and rework env error wrapping
• Do not mock os functions
  • Use filepaths with /tmp for tests instead
  • Only mock functions where filepath can't be specified such as user.Lookup
• Pass only single strings to logger methods
  • Do not assume formatting from logger's interface
  • Allow to change golibs in the future to accept only strings for logger methods
• Prefer empty string comparisons than len(s) == 0
• Firewall and routing use logger.Debug instead of fmt.Println
• Remove SetVerbose and SetDebug methods from firewall and routing
• Log routing teardown
• Default logging level set to info
• Inject command.Cmder to openvpn and firewall
• Pass network values to firewall constructor
• Move duration formatting to qdm12/golibs/format
• internal/loopstate package to manage the state of run loops
• Remove routing's Configurator from firewall's Configurator
• Remove routing's Configurator from openvpn's Configurator
• Common no custom port forwarding obtention implementation for all providers but PIA

Packages rework:

• Constructors return concrete structs
• Constructors and struct fields accept narrow interfaces
• Split interfaces in sub-interfaces
• Split Go files in more smaller Go files
• Add interface compilation checks
• Use internal/loopstate to manage the state of their Run loop
• Add subpackage state to manage the state of the loop thread safely
• Packages reworked:
  • internal/alpine
  • internal/cli
  • internal/dns
  • internal/firewall
  • internal/healthcheck
  • internal/httpproxy
  • internal/openvpn (both loop and configurator)
