mkversion

Overview ¶

mkversion gets version info from git and outputs a bunch of shell variables that get used elsewhere in the build system to embed version numbers into binaries.

If TS_VERSION_LONG and TS_VERSION_GIT_HASH are set, the version comes from the environment instead of git and no checkout is needed. That is also a convenient way to see everything derived from a given version:

TS_VERSION_LONG=1.99.5-t8895cec85 TS_VERSION_GIT_HASH=8895cec85... go run ./cmd/mkversion

See tailscale.com/version/mkversion.InfoFrom for the full set of variables.
