This CL adds caching of built package files in $GOCACHE, so that a second build with a particular configuration will be able to reuse the work done in the first build of that configuration, even if the first build was only "go build" and not "go install", or even if there was an intervening "go install" that wiped out the installed copy of the first build. The benchjuju benchmark runs go build on a specific revision of jujud 10 times. Before this CL: 102.72u 15.29s 21.98r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 105.99u 15.55s 22.71r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 106.49u 15.70s 22.82r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 107.09u 15.72s 22.94r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 108.19u 15.85s 22.78r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 108.92u 16.00s 23.02r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 109.25u 15.82s 23.05r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 109.57u 15.96s 23.11r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 109.86u 15.97s 23.17r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 110.50u 16.05s 23.37r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... After this CL: 113.66u 17.00s 24.17r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 3.85u 0.68s 3.49r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 3.98u 0.72s 3.63r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 4.07u 0.72s 3.57r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 3.98u 0.70s 3.43r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 4.58u 0.70s 3.58r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 3.90u 0.70s 3.46r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 3.85u 0.71s 3.52r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 3.70u 0.69s 3.64r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... 3.79u 0.68s 3.41r go build -o /tmp/jujud github.com/juju/juju/cmd/jujud ... This CL reduces the overall all.bash time from 4m22s to 4m17s on my laptop. Not much faster, but also not slower. See also #4719, #20137, #20372.
