I have created a trac-ticket a while back ( https://www.lyx.org/trac/
ticket/10997 ) and now added the discussion from here to the ticket.

Klaus, did you open a trac ticket for this? It would be great if you
could do that and summarize the conversation.

Hello, it is a good idea to automatically reload background files. This is
not so simple, though, because the change notification can happen at random
times and it is not clear that the code is ready for this. I have an idea
to make it work, but this will need to wait that I am back from holidays.
It is best to open a ticket for now.

Thanks for that great research, Klaus, and all of those details! I'm
CC'ing Guillaume. He has worked on this feature so might have an opinion
on this thread. We might want to eventually open a trac ticket for this
so that it does not get lost in the mail archives.

A direct comparison is probably difficult, as LyX draws especially much
information from background files (macro definitions, TOC, ...).  But both
TeXStudio and Emacs (with *[global-]auto-revert-mode*) automatically reload
files when there is no conflict.



* TeXStudio. Seems to do pretty much what I was trying to achieve. - For an
open file, - If it doesn't have unsaved changes, the file is silently
reloaded from disk.- If it has unsaved changes, a prompt asks if it should
be reloaded.- Background files- cannot contain unsaved changes (apparently
the same as in LyX)- Macro definitions found in background files are
silently reloaded, if the file changes.*
*Emacs with "auto-revert-mode".* Also quite similar.

   - If the buffer contents are unchanged, but the file has changed, the
   buffer is automatically reloaded with only a log message. Checks for
   changes occur periodically every *``auto-revert-interval``* seconds.
   Since Emacs doesn't distinguish between visible and invisible buffers, this
   happens entirely in the background.
   - If the buffer contents are changed, a warning is displayed when the
   user is trying to overwrite the file with the changes made inside Emacs.

Without auto-revert-mode, the user is prompted for a reload when starting
to edit the buffer whose file has been changed.

Probably for historical reasons, Emacs polls the opened files for changes,
which probably incurs some performance overhead. (Setting
*auto-revert-interval* too low is really noticable).

Makes sense. Do you know how any other program behaves in similar
situations? We try to follow convention when we can.
