Subject: [PATCH v3 3/5] [GSOC] ref-filter: --format=%(raw) re-support --perl
Date: Sat, 24 Jul 2021 14:14:19 +0000 [thread overview]
Message-ID: <ac5d98647dad31ebe165daa7cbf84f2b7e5fbe80.1627136062.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1000.v3.git.1627136061.gitgitgadget@gmail.com>
From: ZheNing Hu <adlternative@gmail.com>
Because the perl language can handle binary data correctly,
add the function perl_quote_buf_with_len(), which can specify
the length of the data and prevent the data from being truncated
at '\0' to help `--format="%(raw)"` re-support `--perl`.
