Hi, We use in more of repositories PR template like:
=============================================== Following this checklist to help us incorporate your contribution quickly and easily: - [ ] Make sure there is a [JIRA issue]( https://issues.apache.org/jira/browse/<projectKey>) filed for the change (usually before you start working on it). Trivial changes like typos do not require a JIRA issue. Your pull request should address just this issue, without pulling in other changes. - [ ] Each commit in the pull request should have a meaningful subject line and body. - [ ] Format the pull request title like `[<key>-XXX] - Fixes bug in ApproximateQuantiles`, where you replace `MWRAPPER-XXX` with the appropriate JIRA issue. Best practice is to use the JIRA issue title in the pull request title and in the first line of the commit message. - [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why. - [ ] Run `mvn clean verify` to make sure basic checks pass. A more thorough check will be performed on your pull request automatically. - [ ] You have run the integration tests successfully (`mvn -Prun-its clean verify`). If your pull request is about ~20 lines of code you don't need to sign an [Individual Contributor License Agreement]( https://www.apache.org/licenses/icla.pdf) if you are unsure please ask on the developers list. To make clear that you license your contribution under the [Apache License Version 2.0, January 2004]( http://www.apache.org/licenses/LICENSE-2.0) you have to acknowledge this by using the following check-box. - [ ] I hereby declare this contribution to be licenced under the [Apache License Version 2.0, January 2004]( http://www.apache.org/licenses/LICENSE-2.0) - [ ] In any other case, please file an [Apache Individual Contributor License Agreement](https://www.apache.org/licenses/icla.pdf). =============================================== We prefer linear history on default branches ... So the questions: 1. Should we add a checkbox about squashing, one commit per PR? Of course - we can squash commits during merge - should we inform the contributors about it? 2. Why when PR has less than 20 lines changes we don;t require CLA? Can we accept PR with more than 20 lines and without CLA? Even more, can we accept any PR without CLA? We can read on tha ASF page [1]: All contributors of ideas, code, or documentation to any Apache projects must complete, sign, and submit via email an Individual Contributor License Agreement (ICLA). 3. Should we mention CCLA? [1] https://www.apache.org/licenses/contributor-agreements.html -- Sławomir Jaranowski
