This is a repo with the source code for Nullboard Backup Agent - a small companion utility for Nullboard that lives in the Windows system tray and acts as a storage provider for making automatic backups of NB's boards.
See nullboard.io/backups for details.
The project file is for Visual Studio 2017, so if you are on something newer, it will require a conversion.
The UI is implemented using a couple of private UI libraries that are not the part of this repo. I currently have no plans to publish these, but their functionality should be pretty obvious from how they are used in ui.cpp.
Outside of ui.cpp and with few other exceptions the code
should be reasonably portable. It was certainly written with
portability in mind, so Windows-specific stuff will usally be
clumped together.
The entry point is in entry.cpp. It installs
various safety traps and calls wmain from wmain.cpp,
which then loads the config, parses the args and spaws the engine
and the UI, each running in its own thread. It then simply
loops waiting for either to die.
The engine implements a simple web server that accepts new connections, reads inbound requests and answers to Nullboard's API calls and browser's CORS requests. See engine.cpp for details.
Web server is quite barebone, but it will fail unsupported and malformed requests gracefully.
The UI implements the system tray icon and the "New Backup" dialog. Again, the bare minimum to get Nullboard hooked up and backups rolling.
Asserts are used extensively and they are compiled into Release builds. We really want those invariants to hold, because when they don't, there's no point in continuing. Release version or not. In fact, especially if it's a Release one.
That would be the __enforce macro.
