Subject: [PATCH] [GSOC] ref-filter: solve bugs caused by enumeration
Date: Wed, 05 May 2021 15:31:04 +0000	[thread overview]
Message-ID: <pull.949.git.1620228664666.gitgitgadget@gmail.com> (raw)

From: ZheNing Hu <adlternative@gmail.com>

Johannes Schindelin seems to have introduced a bug in
cc72385f(for-each-ref: let upstream/push optionally
report the remote name), it use `atom->u.remote_ref.option`
which is a member of enumeration in the judgment statement.
When we use other members in the enumeration `used_atom.u`,
and it happened to fill in `remote_ref.push`, this judgment
may still be established and produces errors. So replace the
judgment statement with `starts_with(name, "push")` to fix
the error.

    [GSOC] ref-filter: solve bugs caused by enumeration
    
    This is the problem I found in the implementation of git for-each-ref
    --format="%(notes)".
    
    I added a new option to the enum used_atom.u , but the program seems to
    output the value of "%(push)".
    
    After research, it should be the problem of incorrect use of enumeration
    values here.
    
    Thanks, may the force be with you!
