How to publish the pre compiled binaries.

Setup for Linux, Windows and OSX

Every time a new tag for the latest release is pushed to github the continous integration builds in Travis-CI and AppVeyor will generate the binaries for each platform and architecture, package and publish to the AS3 bucket.

This can be checked in the .travis.yml file and appveyor.yml file. Within the files there are two methods for publishing new binaries for each version, one is if a git tag is detected; the other can be triggered by passing the string [publish binary] in the commit message itself.

We also have an automated make task, we should always use this task to avoid forgetting any steps (like merging into the osx-binaries branch).

The process for generating the binaries, publishing and releasing the npm module should be as follows:

  1. Merge all changes and new features into master.
  2. Bump up version of npm module in package.json.
  3. execute make task: make release

This task will do the following for you:

  1. Generate new tags based on package.json version number
  2. Push tags to Github
  3. Checkout into osx-binaries branch
  4. Merge master into osx-binaries
  5. Push osx-binaries
  6. Checkout master
  7. Finally it will run npm publish

With this we will make sure the binaries for all platforms and architectures will be generated each time a new version is released.

Config Travis, AppVeyor and Github to generate all of the binaries.

Before we are able to run everything stated above some steps need to be taken. Specifically for being able to publish the pre compiled binaries to AWS-S3. The correct keys need to be setup in the travis and appveyor .yml files. This needs to be done by the admin of the repo, in the case of Travis, and the owner of the account, in the case of appveyor.

Setting up secure keys in Travis.

Setting up the keys in Travis is easy if you have ruby and ruby gems installed and working then install:

gem install travis

After the travis gem is installed run the following command for each of the required keys:

travis encrypt SOMEVAR=secretvalue

And substitute the values in the .travis.yml file for the new ones. Detailed instructions can be found here: http://docs.travis-ci.com/user/environment-variables/#Secure-Variables

Setting up secure keys in AppVeyor

It is even easier than Travis, you do not need to install anything, just go to your account and click in encrypt tool, there enter the values in the input field and click encrypt. Same as with Travis we then need to substitute the newly generated values for the old ones.

Detailed instructions can be found here: http://www.appveyor.com/docs/build-configuration#secure-variables

OSX binaries

Since Travis does not support config file for multiple OSs we need to create a new branch that contains a slightly different version of the .travis.yml file to compile for OSX. The branch needs to be called osx-binaries and be based of master once the pre-compiled binaries PR has been merged in.
