Like Go's built-in build/test caching but wish it weren't purely stored on local disk in the $GOCACHE directory?
Want to share your cache over the network between your various machines, coworkers, and CI runs without all that GitHub actions/caches tarring and untarring?
Along with a modification to Go's cmd/go tool (open proposal), this repo lets you write
custom GOCACHE implementations to handle the cache however you'd like.
Currentl 692C y you need to build your own Go toolchain to use this. As of 2023-04-24 it's still an open proposal & work in progress.
First, build your cache child process. For example,
$ go install github.com/bradfitz/go-tool-cache/cmd/go-cacherThen tell Go to use it:
$ GOCACHEPROG=$HOME/go/bin/go-cacher go install stdSee some stats:
$ GOCACHEPROG="$HOME/go/bin/go-cacher --verbose" go install std
Defaulting to cache dir /home/bradfitz/.cache/go-cacher ...
cacher: closing; 548 gets (0 hits, 548 misses, 0 errors); 1090 puts (0 errors)Run it again and watch the hit rate go up:
$ GOCACHEPROG="$HOME/go/bin/go-cacher --verbose" go install std
Defaulting to cache dir /home/bradfitz/.cache/go-cacher ...
cacher: closing; 808 gets (808 hits, 0 misses, 0 errors); 0 puts (0 errors)
