Updater

Warning: This isn't ready for non-Keybase libraries to use yet!

The goals of this library are to provide an updater that:

• Is simple
• Works on all our platforms (at least OS X, Windows, Linux)
• Recovers from non-fatal errors
• Every request or command execution should timeout (nothing blocks)
• Can recover from failures in its environment
• Can run as an unprivileged background service
• Has minimal, vendored dependencies
• Is well tested
• Is secure
• Reports failures and activity
• Can notify the user of any non-transient failures

This updater library is used to support updating (in background and on-demand) for Keybase apps and services.

Packages

The main package is the updater core, there are other support packages:

• command: Executes a command with a timeout
• keybase: Keybase specific behavior for updates
• osx: MacOS specific UI
• process: Utilities to find and terminate Processes
• saltpack: Verify updates with saltpack
• service: Runs the updater as a background service
• sources: Update sources for remote locations (like S3), or locally (for testing)
• test: Test resources
• util: Utilities for updating, such as digests, env, file, http, unzip, etc.
• watchdog: Utility to monitor processes and restart them (like launchd), for use with updater service
• windows: Windows specific UI

Development

This library should pass the gometalinter.

There is a pre-commit hook available:

pip install pre-commit
go get -u github.com/alecthomas/gometalinter
gometalinter --install --update
pre-commit install
pre-commit run -a
