Subject: [PATCH v3 04/11] scalar-diagnose: move 'get_disk_info()' to 'compat/'
Date: Wed, 10 Aug 2022 23:34:26 +0000	[thread overview]
Message-ID: <18f2ba4e0cdd9aea213dc7d0e908c6c0d8eccfd0.1660174473.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1310.v3.git.1660174473.gitgitgadget@gmail.com>

From: Victoria Dye <vdye@github.com>

Move 'get_disk_info()' function into 'compat/'. Although Scalar-specific
code is generally not part of the main Git tree, 'get_disk_info()' will be
used in subsequent patches by additional callers beyond 'scalar diagnose'.
This patch prepares for that change, at which point this platform-specific
code should be part of 'compat/' as a matter of convention.

The function is copied *mostly* verbatim, with two exceptions:

* '#ifdef WIN32' is replaced with '#ifdef GIT_WINDOWS_NATIVE' to allow
  'statvfs' to be used with Cygwin.
* the 'struct strbuf buf' and 'int res' (as well as their corresponding
  cleanup & return) are moved outside of the '#ifdef' block.
