| # This workflow creates a GitHub "release" of a nightly build of the project. | |
| # | |
| # Note: This is just an initial rough attempt, there is a lot of future work | |
| # needed here. A brief summary of TODOs: | |
| # | |
| # - Configure a nice release notes template and switch to generating the title | |
| # and notes instead of hard coding them. | |
| # | |
| # - Do some amount of testing prior to building and uploading the release. | |
| # - Tempting to try to examine existing testing workflow, but maybe better to | |
| # allow re-using any complex parts and do our own testing. That would, for | |
| # example, allow us to narrow or expand the set of tests uses for | |
| # pre-release testing to potentially be different from continuous testing. | |
| # - Some questions around what to do in the event of a failure... error? Where | |
| # does the error go? Create a draft, unpublished release instead? | |
| # | |
| # - Build artifacts for all the different OSes we have GitHub runners for rather | |
| # than just x86 Linux. | |
