What do you mean unneeded changes? how do you prevent this in future?
Alon
Unneeded changes is when you get one line of code fixed due to a bug, and many others re-indented. Best prevention is if people would make sure to use the same conventions. We also have a checkstyle which monitors important issues such as trailing white spaces, localization, etc.
But how do you prevent this in future, not all working in same editor nor same styles. You can say that once in a while you perform cross over auto re-format... I am not native Java programmer but this sounds very strange thing to do, I don't think I know of any project that does that.
The main problem is that people commit stuff they don't touch due to their editor behavior, which tread the whole source as if it was at its disposal, while cation should be taken not to modify extra stuff.
So maybe just to reject patches that touches lines which are not belong to the patch it-self.
Alon
I'm fine with rejecting patches with irrelevant changes. Still sometimes you get new files and this repeats itself. The whole point of a convention is that people keep it. Most major IDEs today can use the same formatting XML we now have. So it's really a matter of self-discipline.
OK, I suggest we start rejecting patches with irrelevant changes, and placing these irrelevant changes in their own patch to be relevant.
I don't think that we can enforce XML formatting for all editors out there... unless there is a cli utility to reformat before commit, or even do this at gerrit side, we should be somewhat flexible.
But these are only my two cents.

Thanks to Ofri we can now both automate it and monitor it using http://maven-java-formatter-plugin.googlecode.com/svn/site/0.3.1/examples.ht....
We should be able to add it to the root pom and make sure it won't happen again.
From a quick look this plugin looks like formatted and not
format-validator, if this is the case it is less useful as we can't add a jenkins job to monitor the expected formatting. I think that we should clean the formatting (once again...) in our code base only after we'll have a valid way to enforce it, otherwise we are going to have the same thread every few months (we already had it twice or more) and we all hate this massive formatting patches that comes after the thread...
