gta is an application which finds Go packages that have deviated from their upstream
source in git. A typical situation is when a project is using a
monorepo.
At build or continuous integration time, you won't have to build every single package
since you will know which packages (and dependencies) have changed.
go get github.com/digitalocean/gta/...After installation, you will have a gta binary in $GOPATH/bin/
List packages that should be tested since they have deviated from master.
gta -include $(go list ./...)List packages that have deviated from the most recent merge commit.
gta -include $(go list ./...) -mergegta builds a list of "dirty" (changed) packages from master, using git. This is useful for determining which
tests to run in larger monorepo style repositories.
gta works by implementing a various set of interfaces, namely the Differ and Packager interfaces.
Note: When using this tool, it is common to hit the maximum number of open file descriptors limit set by your OS. On macOS, this may be a measly 256. Consider raising that maximum to something reasonable with:
sudo ulimit -n 4096
