Subject: [PATCH 1/1] freshen_file(): use NULL `times' for implicit current-time
Date: Tue, 14 Apr 2020 16:27:26 +0200	[thread overview]
Message-ID: <5e95d37d.1c69fb81.2b4ec.ce9f@mx.google.com> (raw)

Update freshen_file() to use a NULL `times', semantically equivalent to
the currently setup, with an explicit `actime' and `modtime' set to the
"current time", but with the advantage that it works with other files
not owned by the current user.

Fixes an issue on shared repos with a split index, where eventually a
user's operation creates a shared index, and another user will later do
an operation that will try to update its freshness, but will instead
raise a warning:
  $ git status
  warning: could not freshen shared index '.git/sharedindex.bd736fa10e0519593fefdb2aec253534470865b2'
