While testing out the report parser for the gitleaks go-gitdiff library against a repository, I encountered output in the form: @@@ -229,4 -229,18446744073709551615 +228,3 @@@ Comment The '18446744073709551615' value is interesting, in that it's a uint64 value storing a signed int64 -1. Along with this, the number of changed lines in the output was actually 5 / 0 / 4 (as opposed to 4 / -1 / 3). I found the '-1' value as the first, second, and third line counts (the code only used at most 2 parents per commit). At first I thought this to only happen on some 0 line change instances, but I also found a diff result that looked like (I added a ' mark before each line to make the spacing obvious): '@@@ -225,4 -237,2 +225,6 @@@ Comment ' +line 1 ' +line 2 ' +line 3 ' +line 4 '- line 5 '++line 6 '++line 7 '+ line 8 ' -line 9 ' -line 10 The reported line counts doesn't match the actual output. Based on other examples plus the documentation, it looks like these are also off by 1 - by my count, it should be 5 / 3 / 7, rather than 4 / 2 / 6.
