Subject: [PATCH] fsmonitor: only enable it in non-bare repositories
Date: Thu, 29 Apr 2021 07:46:01 +0000	[thread overview]
Message-ID: <> (raw)

From: Johannes Schindelin <>

The entire point of the FSMonitor is to monitor the worktree changes in
a more efficient manner than `lstat()`ing all worktree files every time
we refresh the index.

But if there is no worktree, FSMonitor has nothing to monitor.

So let's ignore if an FSMonitor is configured (e.g. in `~/.gitconfig`)
and we're running in a repository without worktree.

    fsmonitor: only enable it in non-bare repositories
    Since I released Git for Windows v2.31.0, with brief interruption of two
    weeks, I enabled the built-in FSMonitor via my user config, and today
    was the first time I did anything in a bare repository. I was somewhat
    surprised that FSMonitor gave me trouble there, as the FSMonitor does
    not even make sense there...
    This patch applies on top of jh/rfc-builtin-fsmonitor (not because it
    fixes a problem in the built-in FSMonitor, the bug existed for a long,
    long time before those patches, but because it would otherwise cause
    merge conflicts with that patch series).
