Hi Otto - Thank you for the contributions! Sorry that it took my a little while to begin sponsoring these uploads but I believe that this is the first git-buildpackage upload that I've sponsored and it took me some time to figure out.

The 16.04 upload looks fine. The 15.10 upload will be ignored since it 15.10 is EOL as of last week.

I'm having some problems with the 14.04 upload. If I run the git diff command that you mentioned in comment 1, I see the same debdiff that you attached in comment 2. However, if I create a source upload based on your git-buildpackage tree and then look at the debdiff between mariadb-5.5_5.5.49-1ubuntu0.14.04.1.dsc and the generated mariadb-5.5_5.5.50-1ubuntu0.14.04.1.dsc, I get very different results. Many files in debian/ are changed. Here's the relevant snippet of the diffstat output:
