Re: Show of hands, how many set USE_NSEC

How many users really build their Git with USE_NSEC=1?

I'm suspecting a status issue in jgit caused by jgit honoring a
millisecond resolution on file modification timestamps, and the
underlying filesystem supporting at least a 1/2 second (or finer)
granularity, but C Git was built without USE_NSEC so it only honors
1 second granularity.

This can cause jgit to think a file is locally modified as the
mtime has data in the tv_nsec field, but C Git set that to 0 in
the index as USE_NSEC wasn't enabled at build time.

When jgit finds an index entry with zero nsec it ignores the subsecond
portion of the file timestamp when comparing.
