Want to contribute? Great: read the page (including the small print at the end).
As an individual, sign the Google Individual Contributor License Agreement (CLA) online. This is required for any of your code to be accepted.
Before you start working on a larger contribution, get in touch with us first through the issue tracker with your idea so that we can help out and possibly guide you. Coordinating up front makes it much easier to avoid frustration later on.
Make sure GOPATH is set in your current shell. The common way is to have something like export GOPATH=$HOME/gocode in your .bashrc file so that it's automatically set in all console sessions.
To get the source code, run
go get github.com/google/pprof
To run the tests, do
cd $GOPATH/src/github.com/google/pprof go test -v ./...
When you wish to work with your own fork of the source (which is required to be able to create a pull request), you‘ll want to get your fork repo as another Git remote in the same github.com/google/pprof directory. Otherwise, if you’ll go get your fork directly, you'll be getting errors like use of internal package not allowed when running tests. To set up the remote do something like
cd $GOPATH/src/github.com/google/pprof git remote add aalexand git@github.com:aalexand/pprof.git git fetch aalexand git checkout -b my-new-feature # hack hack hack go test -v ./... git commit -a -m "Add new feature." git push aalexand
where aalexand is your GitHub user ID. Then proceed to the GitHub UI to send a code review.
All submissions, including submissions by project members, require review. We use GitHub pull requests for this purpose.
The pprof source code is in Go with a bit of JavaScript, CSS and HTML. If you are new to Go, read Effective Go and the summary on typical comments during Go code reviews.
Cover all new functionality with tests. Enable Travis on your forked repo, enable builds of branches and make sure Travis is happily green for the branch with your changes.
The code coverage is measured for each pull request. The code coverage is expected to go up with every change.
Pull requests not meeting the above guidelines will get less attention than good ones, so make sure your submissions are high quality.
Contributions made by corporations are covered by a different agreement than the one above, the Software Grant and Corporate Contributor License Agreement.
