Subject: [PATCH v2 1/4] fsmonitor: option to allow fsmonitor to run against network-mounted repos
Date: Tue, 23 Aug 2022 13:03:37 +0000 [thread overview]
Message-ID: <40ce21e85c970953d57e16f70073fbc2d7aa918d.1661259820.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1326.v2.git.1661259820.gitgitgadget@gmail.com>
From: Eric DeCosta <edecosta@mathworks.com>
Though perhaps not common, there are use cases where users have large,
network-mounted repos. Having the ability to run fsmonitor against
network paths would benefit those users.
Most modern Samba-based filers have the necessary support to enable
fsmonitor on network-mounted repos. As a first step towards enabling
fsmonitor to work against network-mounted repos, introduce a
configuration option, 'fsmonitor.allowRemote'. Setting this option to
true will override the default behavior (erroring-out) when a
network-mounted repo is detected by fsmonitor.
