uploadtool Build Status

Super simple uploading of continuous builds (each push) to GitHub Releases. If this is not the easiest way to upload continuous builds to GitHub Releases, then it is a bug.

Usage

This script is designed to be called from Travis CI after a successful build. By default, this script will delete any pre-existing release tagged with continuous, tag the current state with the name continuous, create a new release with that name, and upload the specified binaries there. For pull requests, it will upload the binaries to transfer.sh instead and post the resulting download URL to the pull request page on GitHub.

  • On https://github.com/settings/tokens, click on "Generate new token" and generate a token with at least the public_repo, repo:status, and repo_deployment scopes
  • On Travis CI, go to the settings of your project at https://travis-ci.com/yourusername/yourrepository/settings
  • Under "Environment Variables", add key GITHUB_TOKEN and the token you generated above as the value. Make sure that "Display value in build log" is set to "OFF"! Also make sure it is only available to your main branch (most of the time, master) to avoid leaking it and prevent uploads for any other branches!
  • In the .travis.yml of your GitHub repository, add something like this (assuming the build artifacts to be uploaded are in out/):
after_success:
  - ls -lh out/* # Assuming you have some files in out/ that you would like to upload
  - wget -c https://github.com/probonopd/uploadtool/raw/master/upload.sh
  - bash upload.sh out/*

branches:
  except:
    - # Do not build tags that we create when we upload to GitHub Releases
    - /^(?i:continuous.*)$/

Environment variables

upload.sh normally only creates one stream of continuous releases for the latest commits that are pushed into (or merged into) the repository.

It's possible to use upload.sh in a more complex manner by setting the environment variable UPLOADTOOL_SUFFIX. If this variable is set to the name of the current tag, then upload.sh will upload a release to the repository (basically reproducing the deploy: feature in .travis.yml).

If UPLOADTOOL_SUFFIX is set to a different text, then this text is used as suffix for the continuous tag that is created for continuous releases. This way, a project can customize what releases are being created. One possible use case for this is to set up continuous builds for feature or test branches:

  if [ ! -z $TRAVIS_BRANCH ] && [ "$TRAVIS_BRANCH" != "master" ] ; then
    export UPLOADTOOL_SUFFIX=$TRAVIS_BRANCH
  fi

This will create builds tagged with continuous for pushes / merges to master and with continuous-<branch-name> for pushes / merges to other branches.

The two environment variables UPLOADTOOL_PR_BODY and UPLOADTOOL_BODY allow the calling script to customize the messages that are posted either for pull requests or merges / pushes. If these variables aren't set, generic default texts are used.

Note that UPLOADTOOL* variables will be used in bash script to form a JSON request, that means some characters like double quotes and new lines need to be escaped - example: export UPLOADTOOL_BODY="\\\"Experimental\\\" version.\nDon't use this.\nTravis CI build log: https://travis-ci.com/$TRAVIS_REPO_SLUG/builds/$TRAVIS_BUILD_ID/"
