Subject: [PATCH v2 10/18] mingw: handle symlinks to directories in `mingw_unlink()`
Date: Fri, 09 Jan 2026 20:05:07 +0000 [thread overview]
Message-ID: <5dc90f9785d8f83f39d79788a3f1b9ed8fa539dc.1767989115.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.2018.v2.git.1767989115.gitgitgadget@gmail.com>
From: Karsten Blees <karsten.blees@gmail•com>
The `_wunlink()` and `DeleteFileW()` functions refuse to delete symlinks
to directories on Windows; The error code would be `ERROR_ACCESS_DENIED`
in that case. Take that error code as an indicator that we need to try
`_wrmdir()` as well. In the best case, it will remove a symlink. In the
worst case, it will fail with the same error code again.
