Weaveworks Build Tools

Included in this repo are tools shared by weave.git and scope.git. They include

• cover: a tool which merges overlapping coverage reports generated by go test
• lint: a script to lint Go project; runs various tools like golint, go vet, errcheck etc
• rebuild-image: a script to rebuild docker images when their input files change; useful when you using docker images to build your software, but you don't want to build the image every time.
• socks: a simple, dockerised SOCKS proxy for getting your laptop onto the Weave network
• test: a script to run all go unit tests in subdirectories, gather the coverage results, and merge them into a single report.
• runner: a tool for running tests in parallel; given each test is suffixed with the number of hosts it requires, and the hosts available are contained in the environment variable HOSTS, the tool will run tests in parallel, on different hosts.
• scheduler: an appengine application that can be used to distribute tests across different shards in CircleCI.

Using build-tools.git

To allow you to tie your code to a specific version of build-tools.git, such that future changes don't break you, we recommendation that you git subtree this repository into your own repository:

git subtree add --prefix tools https://github.com/weaveworks/build-tools.git master --squash

To update the code in build-tools.git, the process is therefore:

• PR into build-tools.git, go through normal review process etc.
• Do git subtree pull --prefix tools https://github.com/weaveworks/build-tools.git master --squash in your repo, and PR that.
