open large file with C code: is it realy should be so slow?

I have problem with emacs responsibility, I work with large enough C header files, and when I want to scroll it using mouse's wheel or page (up|down) keys emacs stop react on any keys, like (ctrl+g), and eats 100% of CPU's time during long period, I wonder is this a bug, or expected behaviour?

Coding systems documentation

dbus library functions

Mark A. Hershberger — 2008-11-29T23:16:33

I'm interested in making a library of common dbus services available in Emacs. Three logical services would be Notify, On Screen Display, and Avahi. Perhaps some of the power management information available via DBus would be useful to battery.el, as well. So, two questions: 1. Would building Emacs Lisp functions to encapsulate some of the DBus information be useful to include in the core? 2. Would it be better to create separate libraries (e.g. notify.el, osd.el, avahi.el) or a single one (e.g. freedesktop-dbus.el) for these functions? Thanks, Mark.

.emacs.d/tramp - written/touched each time you exit Emacs?

Drew Adams — 2008-11-29T23:03:32

Dunno if this helps or is important, but I just fired up Emacs 23 (with my libraries, not emacs -Q), opened Info and a couple files, and then exited Emacs. While Emacs was exiting, I noticed a very brief message about Tramp - too quick for me to read (which is not good, BTW). I did not access any remote files or even try to during the brief session. As far as I know, I made no use of Tramp whatsoever. AFAIK, my own code does not load or use Tramp behind the scene. Curious, I looked around for a file related to Tramp and discovered .emacs.d/tramp, which had just been updated. But the file content is nothing new. I haven't used Tramp in a long time (I've always had problems getting it to work on Windows), and there doesn't seem to be anything new in this file. The only thing that might be new (I'm unfamiliar with the old content) is the last line: ("started" t))) I tried another session of Emacs and saw the same thing - the file `tramp' was touched when I exited Emacs, but the content looks identical.

multi-threaded Emacs

Giuseppe Scrivano — 2008-11-29T13:32:22

Hello, I attached a small patch that enables basic threads in Emacs; it is just a proof of concept and not usable yet, my goal was the execution of the elisp code I included at the bottom. In the new file thread.c these functions are defined: (create-thread) (with-thread id '(code)) (kill-thread id) The first one creates a suspended thread that is waiting for requests. These requests are done by with-thread that allows the execution of '(code) on the specified thread. `kill-thread' is used to terminate a thread execution by its id. It is a prototype and the code is not very clean, still a lot of work must be done in order to have working threads, but I think that have a multi-threaded Emacs worths this effort. My idea is to share global variables among threads while local bindings are done locally to threads. I haven't well investigated all problems that will raise using threads in Emacs, the first one that come to my attention is the garbage collector and at the moment I simply disable GC while the

no executable emacs binary in exec-directory

Lennart Borgman — 2008-11-29T13:00:09

I thought that the currently running emacs binary should be in exec-directory. That does not seem to be the case always. How do you find it?

Meta characters in strings

Eli Zaretskii — 2008-11-29T12:03:46

Is this text from the ELisp manual still correct? Sometimes key sequences are represented as strings. When a string is a key sequence, string elements in the range 128 to 255 represent meta characters (which are large integers) rather than character codes in the range 128 to 255.

A note about Antinews

Richard M Stallman — 2008-11-29T09:17:25

Since the purpose of Antinews is to help people use the previous Emacs version, there is usually no need to mention features that are simply absent in that version. That situation will be clear enough to users without help from the manual. For instance, this < at >item Emacs can no longer be started as a daemon. We decided that having an Emacs sitting silently in the background with no visual manifestation anywhere in sight is too confusing. may not need mentioning, because --daemon will give an error message saying it's not implemented, and other cases aren't affected. The kind of change for which the user really needs help from Antinews is where a feature works _differently_ in the previous version. In those cases, the user might have trouble figuring out how to use the old version without some sort of help.

Excess consing comes from x-gtk-map-stock

Chong Yidong — 2008-11-28T22:38:02

I think the excess consing, leading to frequent garbage collection, comes from x-gtk-map-stock. This is called by update_frame_tool_bar on each redisplay, for each tool-bar item. Each call advances consing_since_gc by about 400 bytes, and this adds up rather quickly.

server-window is not mentioned very much

Lennart Borgman — 2008-11-27T14:17:47

Is not `server-window' a rather important option for those using Emacs client? Shouldn't the possibilities it gives be mentioned in the manual?

Concerning delete-by-moving-to-trash on free systems

Tassilo Horn — 2008-11-27T10:09:27

Hi all, I've just found out about that option, and basically it's nice. But in order to integrate emacs on the modern GNU desktop the moving to trash should be in compliance with the Freedesktop.org Trash Specification [1] on systems that support it. This spec enables undoing of deletions which requires storage of some metadata of course. Beside from not conforming to this standard, the current implementation has other drawbacks. - Delete a directory foo which contains the files a and b recursively (from within dired). Then goto the trash-directory. Now foo, a and b are side by side. - Now delete another file named a. This file is really deleted, because a already exists in trash. (Overwriting would be as bad as the current decision.) Bye, Tassilo __________ [1] http://www.freedesktop.org/wiki/Specifications/trash-spec?action=show&redirect=Standards%2Ftrash-spec
