License Clearing

This is a page about the process of License Clearing — getting Apache Software Grant Agreements (SGAs) or Individual Contributor License Agreements(ICLAs) for all NuttX contributors. This needs to be done before NuttX can graduate from podling stage.

Here's the process  we're following. Update this if it changes.

Overview:

1. For each section, clear it:
   1. Get all authors of all files.
   2. Do the easy files first:
      1. Find the subset of files that have only NuttX committers as authors. (Use the authors.sh tool.)
      2. Mark the files' licenses using Fossology
      3. Get Individual Contributor License Agreements (ICLAs) from all the committers that don't have them. Update the list of authors with ICLAs.
      4. When all ICLAs for these files have been submitted, clear the files in Fossology.
      5. Update the license headers with the licenseheaders.py tool
      6. Generate a PR for Greg and others to carefully review
   3. Do the harder files next:
      1. Find the subset of files that have authors who are not NuttX committers. (Use the authors.sh tool.)
      2. Mark the files' licenses using Fossology
      3. Get ICLAs from all the authors that don't have them. Update the list of authors with ICLAs.
      4. When all ICLAs for these files have been submitted, clear the files in Fossology.
      5. Update the license headers with the licenseheaders.py tool
      6. Generate a PR for Greg and others to carefully review
   4. Mark this section done.
2. When all sections are cleared, we are done. Generate a report and submit to Apache.
3. Celebrate!

Practices:

• PRs that change licenses should have no other changes in them
  • No nxstyle changes
  • No code changes

Project Plan

• We need to make progress each release
• The plan of attack on which files/sections to do each release should go here!
