Bump github.com/fsnotify/fsnotify from 1.5.4 to 1.6.0 in /agent

[dependabot]

Bumps github.com/fsnotify/fsnotify from 1.5.4 to 1.6.0.

Release notes

Sourced from github.com/fsnotify/fsnotify's releases.

v1.6.0

This version of fsnotify needs Go 1.16 (this was already the case since 1.5.1, but not documented). It also increases the minimum Linux version to 2.6.32.

Additions

• all: add Event.Has() and Op.Has() (#477)

  This makes checking events a lot easier; for example:

  if event.Op&Write == Write && !(event.Op&Remove == Remove) {
  }
  

  Becomes:

  if event.Has(Write) && !event.Has(Remove) {
  }
  

• all: add cmd/fsnotify (#463)

  A command-line utility for testing and some examples.

Changes and fixes

• inotify: don't ignore events for files that don't exist (#260, #470)

  Previously the inotify watcher would call os.Lstat() to check if a file still exists before emitting events.

  This was inconsistent with other platforms and resulted in inconsistent event reporting (e.g. when a file is quickly removed and re-created), and generally a source of confusion. It was added in 2013 to fix a memory leak that no longer exists.

• all: return ErrNonExistentWatch when Remove() is called on a path that's not watched (#460)

• inotify: replace epoll() with non-blocking inotify (#434)

  Non-blocking inotify was not generally available at the time this library was written in 2014, but now it is. As a result, the minimum Linux version is bumped from 2.6.27 to 2.6.32. This hugely simplifies the code and is faster.

• kqueue: don't check for events every 100ms (#480)

  The watcher would wake up every 100ms, even when there was nothing to do. Now it waits until there is something to do.

• macos: retry opening files on EINTR (#475)

• kqueue: skip unreadable files (#479)

  kqueue requires a file descriptor for every file in a directory; this would fail if a file was unreadable by the current user. Now these files are simply skipped.

• windows: fix renaming a watched directory if the parent is also watched (#370)

• windows: increase buffer size from 4K to 64K (#485)

... (truncated)
