Add disallow multiple empty lines #1427

merged 3 commits into from Dec 13, 2019


Copy link

@sehrope sehrope commented Feb 27, 2019

Adds checkstyle rule for disallowing multiple empty newlines. Split into three commits:

  • First one adds an unrelated newline in dist.xml
  • Second one is the "big" one that is kind of funny because the diff excluding newlines is totally empty.
  • Third one adds the new checkstyle rule

The majority of the deletions in the second commit are doubled newlines. There's also a handful of manual single newline cleanups for tests to align the code blocks (ex: see pgjdbc/src/test/java/org/postgresql/test/jdbc42/

Amazingly even with the flurry of activity everything rebased cleanly 🎉. I also added a few more fixes for new code that has gone in since Feb.

Rrunning git diff --ignore-blank-lines HEAD~3 shows nothing changing outside the newlines and checkstyle config:

@davecramer Once this passes CI it should be good to merge.
