Re: undo limit vs. .deb

[Dan Jacobson]

RMS> Please tell me precisely what to type, starting with `emacs -Q',
Need -q, not -Q. So probably a Debian problem. P.S. -Q not on the
emacs-snapshot man page here in Debian.

With Debian emacs-snapshot package, version 1:20060817-1
$ emacs -q /var/cache/apt/archives/mediawiki1.7_1.7.1-1_all.deb
gives a *Warning* buffer with:
     Warning (undo): Buffer `mediawiki1.7_1.7.1-1_all.deb-DATA' undo
     info was 3265340 bytes long.
     The undo info was discarded because it exceeded `undo-outer-limit'.

     This is normal if you executed a command that made a huge change
     to the buffer.  In that case, to prevent similar problems in the
     future, set `undo-outer-limit' to a value that is large enough to
     cover the maximum size of normal changes you expect a single
     command to make, but not so large that it might exceed the
     maximum memory allotted to Emacs.

     If you did not execute any such command, the situation is
     probably due to a bug and you should report it.

     You can disable the popping up of this buffer by adding the entry
     (undo discard-info) to the user option `warning-suppress-types'.

(Why is undo recording going on here?)
