From 7815647d6582c0a4900be2e1de6c5e61272c496b Mon Sep 17 00:00:00 2001 From: Daniel Stenberg <daniel@haxx.se> Date: Tue, 25 Apr 2023 08:28:01 +0200 Subject: [PATCH] lib: unify the upload/method handling By making sure we set state.upload based on the set.method value and not independently as set.upload, we reduce confusion and mixup risks, both internally and externally.
