Subject: [PATCH 05/23] fsmonitor--daemon: add a built-in fsmonitor daemon
Date: Thu, 01 Apr 2021 15:40:47 +0000
Message-ID: <95d511d83b1211f24aeb17edbd4918750f406ece.1617291666.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.923.git.1617291666.gitgitgadget@gmail.com>

From: Jeff Hostetler <jeffhost@microsoft.com>

Create a built-in file system monitoring daemon that can be used by
the existing `fsmonitor` feature (protocol API and index extension)
to improve the performance of various Git commands, such as `status`.

The `fsmonitor--daemon` feature builds upon the `Simple IPC` API and
provides an alternative to hook access to existing fsmonitors such
as `watchman`.

This commit merely adds the new command without any functionality.
