From b5f4dcb598bb369c960f715fcd5c9ccf4112e026 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 5 Sep 2017 08:14:50 -0400 Subject: [PATCH] tempfile: factor out deactivation When we deactivate a tempfile, we also have to clean up the "filename" strbuf. Let's pull this out into its own function to keep the logic in one place (which will become more important when a future patch makes it more complicated). Note that we can use the same function when deactivating an object that _isn't_ actually active yet (like when we hit an error creating a tempfile). These callsites don't currently reset the "active" flag to 0, but it's OK to do so (it's just a noop for these cases).
