Subject: [PATCH] ci: do not die on deprecated-declarations warning
Date: Fri, 13 Jan 2023 19:47:12 -0800 [thread overview]
Message-ID: <xmqqv8l9n5fj.fsf@gitster.g> (raw)
Like a recent GitHub CI run on linux-musl [1] shows, we seem to be
getting a bunch of errors of the form:
Error: http.c:1002:9: 'CURLOPT_REDIR_PROTOCOLS' is deprecated:
since 7.85.0. Use CURLOPT_REDIR_PROTOCOLS_STR
[-Werror=deprecated-declarations]
For some of them, it may be reasonable to follow the deprecation
notice and update the code, but some symbols like the above is not.
According to the release table [2], 7.85.0 that deprecates
CURLOPT_REDIR_PROTOCOLS was released on 2022-08-31, less than a year
ago, and according to the symbols-in-versions table [3],
CURLOPT_REDIR_PROTOCOLS_STR was introduced in 7.85.0, so it will
make us incompatible with anything older than a year if we rewrote
the call as the message suggests.
Make sure that we won't break the build when -Wdeprecated-declarations
triggers.
