When a file's timestamp has been changed, but the contents are still the
same, what should be the behavior of emacs be? With the emacs that I am
using (development version):
GNU Emacs 24.3.50.1 (i686-pc-linux-gnu, GTK+ Version 3.6.3)
of 2013-05-01 on bonsai
It thinks the file is changed. Here is what I do:
- Open a file, edit it and then save.
- use the "touch" command to update the time stamp of this file.
- Wait way more than the auto revert interval (which is set to 5 seconds
in my case).
- Try to make a change to the buffer corresponding to this file.
At this point, emacs says that the file has changed and asks whether I
really want to edit it. I was expecting emacs to auto revert this buffer
and allow me to edit it without further questions. So my question is, am
I looking at a bug, or a feature?

GNU Emacs will never automatically return to a previous state of the file. That's left up to you. What it does is, that it warns you, that it gives you information to make better decisions.
This is OK with me.

Don't just do something, sit there.

I don't want emacs to return the file to its previous state.
global-auto-revert-mode doesn't do that, anyway. global-auto-revert-mode
detects that a file has been changed on disc, and if I haven't made any
edits to that file, it reverts the file _AUTOMATICALL_, without asking
any questions. So that works as expected.
What doesn't work is, if only the timestamp of the file changes (touch
filename), then emacs doesn't autorevert it, and instead tells me that
it changed and asks whether I want to really edit it.
Hope this makes it clear...

when I 'touch' on Windows or Linux, it does what you expect, not what
you're observing. It autoreverts the file.
I have this in .emacs:
(autoload 'auto-revert-mode "autorevert" nil t)
(autoload 'turn-on-auto-revert-mode "autorevert" nil nil)
(autoload 'global-auto-revert-mode "autorevert" nil t)
(global-auto-revert-mode 1)
(setq auto-revert-interval 2)
(global-set-key "\C-cr" 'revert-buffer)

Hi, I have sent this message to help-gnu-emacs, but I thought maybe
development list is better, because I am using a development version.
Here it goes:

same, what should be the behavior of emacs be? With the emacs that I am

I could reproduce the problem. I will check tomorrow what's up. Likely,
it is because the new file change notification mechanism introduced with
Emacs 24.3.50.
Best regards, Michael.
