Using with-temp-buffer seems like a good idea. Does it ever make sense to save undo information in a temporary buffer? If not, I suggest to disable it in with-temp-buffer.

Bill Wohler wrote: OK, it's back. Here's the message: Buffer `*desktop*' undo info is 3159101 bytes long; discard it? (yes or no) The patch below should solve your problem, or part of your problem. There is no reason for the `*desktop*' buffer to accumulate a huge undo entry just to allow you to erase the buffer completely using `M-x undo'. So the patch below disables undo while desktop.el writes all these entries in the *desktop* buffer. After that, undo is re-enabled however. So if you then inadvertently mess up the buffer, repeated undo will restore the buffer to what desktop.el wrote in it. But one more undo will not erase the buffer. Instead, it will tell you that there is no further undo info. I said that it might solve part of your problem. The question is whether the 3M of undo is legitimate. Take a look at what is in that buffer. Does the huge size of the buffer seem legitimate, because there really is that much info to save? I guess that you know that you can produce the buffer using `M-x desktop-save'. I believe that my patch should be applied regardless of whether the 3M is legitimate, but if it is not, additional changes may be necessary. ===File ~/desktop.el-diff=== *** desktop.el 10 Feb 2006 08:34:46 -0600 1.99 --- desktop.el 11 May 2006 20:42:50 -0500 *** *** 766,804 (eager desktop-restore-eager) (buf (get-buffer-create *desktop*))) (set-buffer buf) !

From my previous reply: I said that it might solve part of your problem. The question is whether the 3M of undo is legitimate. Take a look at what is in that buffer. Does the huge size of the buffer seem legitimate, because there really is that much info to save? I guess that you know that you can produce the buffer using `M-x desktop-save'. Well, the size of the undo info is not necessarily related to the size of the buffer. In my setup, after `M-x desktop-save', I get a *desktop* buffer of size 2943, but my buffer-undo-list (_without_ my patch applied) is very small: (nil (1 . 2944) (t 0 . 0)) I guess that if you created the *desktop* buffer and did `C-h v buffer-undo-list' in it, you would get a really huge *Help* buffer, assuming it would not make your Emacs crash.

Re: Big desktop undo buffer crashes Emacs
I believe that we can forget about that potential second undo problem. It is apparently when you do `M-x desktop-save' while you already have a *desktop* buffer that you can accumulate a large undo entry proportional to the size of the buffer. This seems to happen as a result of the call to `erase-buffer'. But after my patch, recording of undo info during the call to `erase-buffer' is disabled anyway.

From `(elisp)Timers': It is usually a bad idea for timer functions to alter buffer contents. When they do, they usually should call `undo-boundary' both before and after changing the buffer, to separate the timer's changes from user commands' changes and prevent a single undo entry from growing to be quite large. So it is no surprise that you accumulated such a large single undo entry. Thanks for the information. Since I don't understand the mechanics of desktop, I have a couple of questions about that. First, I thought desktop-save just saves the buffer to a file. Is it really altering the the *desktop* buffer? Oh, running desktop-save a couple of times shows that it at least updates the Created header field. OK, desktop-save must gather buffer information, write it to *desktop*, and *then* save it to a file. Right? Second, I also don't understand the mechanics of undo very well. I was under the impression that undo-boundary only grouped a set of changes into a single undo entry. As I sit here writing, only a limited amount of changes are saved and at some point the oldest undo information will be discarded. How is the timer different? Interesting, as I typed this, the timer had run a couple of times (I was thinking and trying to understand desktop and undo). I re-ran `C-h v buffer-undo-list' a few times too. It just produced buffers with only 35 kB, not 68 kB. Right now my desktop buffer is 32 kB; So that is approximately 32 kB every five minutes. After eight hours, you exceed 3M. Anyway, my patch, or disabling undo, completely gets rid of this problem. So, which one should I apply? Before I fix my timer ;-). If the *desktop* buffer is ephemeral and recreated when desktop-save is run, it seems that disabling undo is the proper course of action. Otherwise, preserving undo while protecting against abuse would be wise.
