Watch files and translate the changes into salt events
:depends: - pyinotify Python module >= 0.9.5
:Caution: Using generic mask options like open, access, ignored, and
closed_nowrite with reactors can easily cause the reactor
to loop on itself. To mitigate this behavior, consider
setting the `disable_during_state_run` flag to `True` in
the beacon configuration.
:note: The `inotify` beacon only works on OSes that have `inotify`
kernel support.

Watch the configured files
Example Config
.. code-block:: yaml
beacons:
inotify:
- files:
/path/to/file/or/dir:
mask:
- open
- create
- close_write
recurse: True
auto_add: True
exclude:
- /path/to/file/or/dir/exclude1
- /path/to/file/or/dir/exclude2
- /path/to/file/or/dir/regex[a-m]*$:
regex: True
- coalesce: True
The mask list can contain the following events (the default mask is create,
delete, and modify):
* access - File accessed
* attrib - File metadata changed
* close_nowrite - Unwritable file closed
* close_write - Writable file closed
* create - File created in watched directory
* delete - File deleted from watched directory
* delete_self - Watched file or directory deleted
* modify - File modified
* moved_from - File moved out of watched directory
* moved_to - File moved into watched directory
* move_self - Watched file moved
* open - File opened
The mask can also contain the following options:
* dont_follow - Don't dereference symbolic links
* excl_unlink - Omit events for children after they have been unlinked
* oneshot - Remove watch after one event
* onlydir - Operate only if name is directory
recurse:
Recursively watch files in the directory
auto_add:
Automatically start watching files that are created in the watched directory
exclude:
Exclude directories or files from triggering events in the watched directory.
Can use regex if regex is set to True
coalesce:
If this coalescing option is enabled, events are filtered based on
their unicity, only unique events are enqueued, doublons are discarded.
An event is unique when the combination of its fields (wd, mask,
cookie, name) is unique among events of a same batch. After a batch of
events is processed any events are accepted again.
This option is top-level (at the same level as the path) and therefore
affects all paths that are being watched. This is due to this option
being at the Notifier level in pyinotify.
