Comment (by chrisbainbridge):
The [https://code.djangoproject.com/attachment/ticket/24875/0001-Detect-
moved-file-when-using-inotify-polling.patch patch I provided in bug
#24875] fixed this issue for me. Required flags:
{{{
pyinotify.IN_CREATE | pyinotify.IN_DELETE_SELF | pyinotify.IN_MOVE_SELF
}}}
@orzel Try the following test code, run as `python test dir_to_watch` then
start vim and edit/save a file in the test directory. The notifier loop
will print whatever inotify events occur:
{{{
import sys
import pyinotify
wm = pyinotify.WatchManager()
wm.add_watch(sys.argv[1], pyinotify.ALL_EVENTS)
notifier = pyinotify.Notifier(wm)
notifier.loop()
}}}
Django does not watch the whole directory, but instead generates a list of
paths to watch based on the current python imports. This means there are
some cases where files are not initially watched - basically any python
file that is dynamically loaded at runtime, such as a view specified by a
string literal in urls.py. These files will be watched after the
corresponding web page has been loaded for the first time.
You can see the current list of paths being watched by adding a print
statement to `django/utils/autoreload.py:inotify_code_changed()`
