Release Process

1. Create a new version

  • Update AUTHORS

    npm run update-authors
    

    Commit if necessary. The commit message should be "authors".

  • Write the changelog

    You can use git log --oneline <last version tag>..HEAD to get a list of changes.

    Summarize them concisely in CHANGELOG.md. The commit message should be "changelog".

  • Update the version

    npm version [major|minor|patch]
    

    This creates both a commit and a git tag.

  • Make a PR

    Once the PR is reviewed, merge it:

    git push origin <branch-name>:master
    

    This makes it so that the commit hash on master matches the commit hash of the version tag.

    Finally, run:

    git push --tags
    

2. Create the release binaries

  • On a Mac:

    npm run package -- darwin --sign
    npm run package -- linux --sign
    
  • On Windows, or in a Windows VM:

    npm run package -- win32 --sign
    
  • Then, upload the release binaries to Github:

    npm run gh-release
    

    Follow the URL to a newly created Github release page. Manually upload the binaries from webtorrent-desktop/dist/. Open the previous release in another tab, and make sure that you are uploading the same set of files, no more, no less.

3. Test it

This is the most important part.

  • Manually download the binaries for each platform from Github.

Do not use your locally built binaries. Modern OSs treat executables differently if they've been downloaded, even though the files are byte for byte identical. This ensures that the codesigning worked and is valid.

  • Smoke test WebTorrent Desktop on each platform.

    See Smoke Tests below for details. Open DevTools on Windows and Mac, and ensure that the auto updater is running. If the auto updater does not run, users will successfully auto update to this new version, and then be stuck there forever.

4. Ship it

  • Update the website

    Create a pull request in webtorrent.io. Update config.js, updating the desktop app version.

    As soon as this PR is merged, Jenkins will automatically redeploy the WebTorrent website, and hundreds of thousands of users around the world will start auto updating. Merge with care.

Smoke Tests

Before a release, check that the following basic use cases work correctly:

  1. Click "Play" to stream a built-in torrent (e.g. Sintel)
  • Ensure that seeking to undownloaded region works and plays immediately.
  • Ensure that sintel.mp4 gets downloaded to ~/Downloads.
  1. Check that the auto-updater works
  • Open the console and check for the line "No update available" to indicate
  1. Add a new .torrent file via drag-and-drop.
  • Ensure that it gets added to the list and starts downloading
  1. Remove a torrent from the client
  • Ensure that the file is removed from ~/Downloads
  1. Create and seed a new a torrent via drag-and-drop.
  • Ensure that the torrent gets created and seeding begins.
