Subject: [PATCH v4 1/2] negative-refspec: fix segfault on : refspec
Date: Tue, 22 Dec 2020 01:11:52 +0000 [thread overview]
Message-ID: <e59ff29bdef9ce6bbdf8fbab307178e3e983cf2c.1608599513.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.820.v4.git.1608599513.gitgitgadget@gmail.com>
From: Nipunn Koorapati <nipunn@dropbox.com>
The logic added to check for negative pathspec match by c0192df630
(refspec: add support for negative refspecs, 2020-09-30) looks at
refspec->src assuming it is never NULL, however when
remote.origin.push is set to ":", then refspec->src is NULL,
causing a segfault within strcmp.
Tell git to handle matching refspec by adding the needle to the
set of positively matched refspecs, since matching ":" refspecs
match anything as src.
Add test for matching refspec pushes fetch-negative-refspec
both individually and in combination with a negative refspec.
