Sorry, I haven't read the series carefully yet (but from a skim I'm
happy with the overall direction). It does seem to cause failures in
t4212, though. For example:
expecting success:
commit=$(munge_author_date HEAD 18446744073709551617) &&
echo "Thu Jan 1 00:00:00 1970 +0000" >expect &&
git log -1 --format=%ad $commit >actual &&
test_cmp expect actual
fatal: Timestamp too large for this system: 18446744073709551615
not ok 7 - date parser recognizes integer overflow
We used to convert overflows into a sentinel time, but now we die. I
originally chose the sentinel approach because it lets you use the tools
to examine and recover from the broken state. I could be convinced that
dying is better, but clearly we'd need to at least update the tests.
