Subject: [PATCH v3 19/34] fsmonitor-fs-listen-win32: implement FSMonitor backend on Windows
Date: Thu, 01 Jul 2021 14:47:29 +0000	[thread overview]
Message-ID: <5bba5eb3d1bd172f09fdf6eb2e9b8ac4dd7f940f.1625150864.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.923.v3.git.1625150864.gitgitgadget@gmail.com>

From: Jeff Hostetler <jeffhost@microsoft.com>

Teach the win32 backend to register a watch on the working tree
root directory (recursively).  Also watch the <gitdir> if it is
not inside the working tree.  And to collect path change notifications
into batches and publish.
