Description Michael Catanzaro 2016-09-05 09:10:29 PDT
I've been seeing this warning spam from prepare-ChangeLog for a year or so now:

This change looks wrong. The argument is extraneous for some cases, and in that case it seems perl warns, but it is needed for others: $svn{A}, $svn{R}, $git{C} and $git{R}.
Comment 3 Michael Catanzaro 2016-09-05 11:45:50 PDT
You're right. I tested $git{"A"} because I was confused by the Perl and wanted to make sure I wasn't breaking anything, but that was dumb as it was the only git case that didn't use the extra format argument.

I tried moving the sprintf instead and it seems to work, though maybe there's a better Perl way to write this.

Comment 9 Michael Catanzaro 2016-09-06 07:45:03 PDT
The problem with the patch I landed: I failed to test the simple case of modifying an existing file. In that case, $original is unset. That's why the existing code checks if $original is defined when creating the lookup table. In the case of git, we know if there's no $original file then it wasn't copied or renamed, so we don't need to add it to the lookup table.

It raises the question of how I managed to generate the changelog for that commit. I think I just copy/pasted it from the original patch instead of running prepare-ChangeLog to do it. Dumb!
