bug#11227: lock files not deleted

[Kurt Harriger]

I frequently find that lock files such as .#core.clj are not deleted. 
For some reason files named .#name cause other commandline tools to fail
on OS X such as grep -R pattern . and build tools like leiningen.  

I have not experienced any emacs crashes reciently so I don't believe
these files were left behind by unclean termination, but have yet to
consistently reproduce the issue.  

I do not like to save files manually, so I have autosave configured to
automatically save dirty buffers every second, so these lock files 
should not need to exist for more than a second but for what ever reason
I keep finding them.

My autosave config (and full emacs config) is here:
https://bitbucket.org/kurtharriger/emacs.d/src/20de37046196/init.d/60-auto-save.el

Would it is possible to save lock files elsewhere? or change the
pattern filename.emacslock or something that would not result in other
commandline tools failing but I couldnt find any settings for this?

Patch to disable lock files (nothing really came of it):

I'll give it a try.   
I noticed that this patch is not in the master branch and I read through the associated thread and although there was discussion of alternate implementation no-one stepped up to implement the alternative implementation and there did not appear to be any objections to this patch as is? any chance this could be merged into master?

Thanks!

I'd be happy to add it at some point, if there no objections.

Hi,

Re your patch from
http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg01020.html

to disable lock files.

I would like to apply this, but I noticed that you don't have a
copyright assignment for Emacs. I see you completed one for Gnus some
months ago. Would you mind doing another one for Emacs?
(It's a shame the first one was not for Emacs, since that would have
covered Gnus as well, but vice versa does not apply.)

(I know you said you would place it in the public domain, but we would
still need paperwork for that. An assignment is better, if you don't
mind.)

Not at all.  Caveat: the last time it took the administrator months to
process it.

I asked for a blanket agreement so I wouldn't have to do this over and
over again, but FSF said their lawyers had told them not to do that.

close 11227 24.2
stop

In the current trunk, creation of lockfiles can now be prevented through
the `create-lockfiles' option.
