buildinfo

Overview ¶

Package buildinfo names the build a binary came from. Both binaries report the same string everywhere a version appears: the version subcommand, the startup log line, and the agent's reported version on the sync stream, which the console shows among a workload's host facts.

The string is semantic-version shaped, with the commit as build metadata:

v0.1.0+6007581f652b        a build of a tagged commit
dev+f347cd966f58           a from-source build of an untagged commit
dev+f347cd966f58.dirty     the same, with uncommitted changes
dev+unknown                a build that carries no commit at all

The commit comes from what the Go toolchain embeds on every build made in a git checkout (vcs.revision), so a plain `go build` needs no flags. A release build may set both values at link time instead:

-ldflags "-X github.com/innerwall-dev/innerwall/internal/buildinfo.version=v0.1.0
          -X github.com/innerwall-dev/innerwall/internal/buildinfo.commit=<sha>"
