From d0e9983980a25e0c398cc03342e5ad22ef85b8a8 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 21 Sep 2017 02:23:24 -0400 Subject: curl_trace(): eliminate switch fallthrough Our trace handler is called by curl with a curl_infotype variable to interpret its data field. For most types we print the data and then break out of the switch. But for CURLINFO_TEXT, we print data and then fall through to the "default" case, which does the exact same thing (nothing!) that breaking out of the switch would. This is probably a leftover from an early iteration of the patch where the code after the switch _did_ do something interesting that was unique to the non-text case arms. But in its current form, this fallthrough is merely confusing (and causes gcc's -Wimplicit-fallthrough to complain). Let's make CURLINFO_TEXT like the other case arms, and push the default arm to the end where it's more obviously a catch-all.
