Subject: [PATCH 3/7] git: ->fail invokes current callback
Date: Thu, 14 Oct 2021 13:16:05 +0000 [thread overview]
Message-ID: <20211014131609.829-4-e@80x24.org> (raw)
In-Reply-To: <20211014131609.829-1-e@80x24.org>
While we try to invoke all pending callbacks to force error
handling, the current callback wasn't getting invoked on
invoked on async_abort if my_read/my_readline failed.
