Re: [PATCH v2 20/27] update-ref --stdin: Reimplement using reference transactions

Michael Haggerty [off-list ref] writes:

I assumed that rolling back a non-consummated transaction in the case of
early program death should be the responsibility of the library, not of
the caller.  If I'm correct, the caller(s) won't have to be modified
when the atexit facility is added, so I don't see a reason to add it
before it is needed by a concrete backend.

But you suggest that the caller should be involved.

I didn't say "should".  If the library can automatically rollback
without being called upon die() anywhere in the system, that is
better.  The suggestion was because I didn't think you were shooting
for such a completeness in the library part, and a possible way out
is for the caller to help.
