Subject: [Tarantool-patches] [PATCH v2] lua/utils: fix fiber->fid print in cord_on_yield
Date: Fri, 14 May 2021 13:32:51 +0300	[thread overview]
Message-ID: <YJ5R0zqzmgCYk/K9@grain> (raw)
In-Reply-To: <20210514101947.106581-1-gorcunov@gmail.com>

This fixes a nit in commit 6af473778
(fiber: use uint64_t for fiber IDs).

Since lua_pushfstring doesn't support %llu format it
breaks the test

app-tap/gh-1700-abort-recording-on-fiber-switch.test.lua
