This is a follow-up to the already-integrated topic for dropping support for older curl versions submitted before the v2.33 release[1]. No verions become unsupported in this topic, this is a mere clean-up. There were a couple of cases where we either already dropped support for something, but got the curl version wrong in a macro comparison, or just got the version wrong. That's now corrected. But more importantly this introduces a git-curl-compat.h header which centarlizes all our curl version dependencies, and any compatability shims we've got to deal with those versions. This makes the code much easier to read and maintain than inline LIBCURL_VERSION_NUM version comparisons, and will make any future dropping of supported curl versions in the future easier to perform & review. 1. https://lore.kernel.org/git/cover-v4-0.5-00000000000-20210730T175650Z-avarab@xxxxxxxxx/ Ævar Arnfjörð Bjarmason (5): http: drop support for curl < 7.18.0 (again) http: correct curl version check for CURLOPT_PINNEDPUBLICKEY http: correct version check for CURL_HTTP_VERSION_2_0 http: centralize the accounting of libcurl dependencies http: don't hardcode the value of CURL_SOCKOPT_OK git-curl-compat.h | 123 ++++++++++++++++++++++++++++++++++++++++++++++ http.c | 39 +++++++-------- imap-send.c | 2 +- 3 files changed, 141 insertions(+), 23 deletions(-) create mode 100644 git-curl-compat.h -- 2.33.0.825.g2bf60429931
