Since 4aff646d17 (archive-zip: mark text files in archives, 2015-03-05), the zip archiver will look at the userdiff driver to decide whether a file is text or binary. This usually doesn't need to look any further than the attributes themselves (e.g., "-diff", etc). But if the user defines a custom driver like "diff=foo", we need to look at "diff.foo.binary" in the config. Prior to this patch, we didn't actually load it.
Signed-off-by: Jeff King <peff@peff.net> --- I'd be surprised if anybody actually triggered this in practice. I don't think any of the custom-driver fields except "binary" matter, and using direct attributes is almost always easier than setting up a custom driver. Though you could also do trickery with:
git -c diff.default.binary=true archive ...
if you wanted to be really clever.
I ran across this while investigating a case where somebody's zipfile was all marked as binary (it turned out not to be related; the issue was just that their Git was pre-4aff646d17).
I also happened to notice that zipfiles are created using the local timezone (because they have no notion of the timezone, so we have to pick _something_). That's probably the least-terrible option, but it was certainly surprising to me when I tried to bit-for-bit reproduce a zipfile from GitHub on my local machine.
