occasional pause (or stutter) on win32 emacs 23.0.95

occasional pause (or stutter) on win32 emacs 23.0.95

[Matthew Daniel]

Hello,

I honestly tried searching for other occurrences of my problem in the
mailing list archives, but unfortunately "pause" is also the name of
an elisp function.

Periodically, emacs will pause - often with the Windows hourglass. It
does accept my keystrokes, because when it "releases" they appear in
the current buffer. These pauses last about 3 seconds, and I would not
characterize them as variable in length. I have not found any
systematic way of inducing the pause, but they happen pretty
frequently during a C-x C-s sequence.

I have experienced this on both Windows XP 32-bit and Windows Vista
64-bit, on two separate machines (both Dells, and their only
commonality is that they both use an Intel X-25M SSD).

My question is not necessarily "what is causing this", as I understand
that my description is very hand-wavey. However, if someone can tell
me what to check for, or how one would go about troubleshooting this
behavior, I will do my best to help me help you help me. :-)

I have already tried starting `emacs.exe -q --no-site-file` to ensure
it isn't some local configuration problem.

  Any insight will be greatly appreciated,

I had similar problems using the official Gnu Emacs release on Windows 
Vista, using an HP EliteBook. The program would freeze up periodically, 
not responding to anything for several seconds at a time. This happened 
often enough (once every few minutes or so) to make it unusable. Same 
thing with the version shipped with Cygwin.

I switched to the version packaged by Vincent Goulet, and now everything 
works very smoothly. I'm not sure what he does, but it fixed my problem.

It does not look as Vincent has modified any files, just added some
elisp files. Maybe someone should ask him how he compiles Emacs (if he
does that)?

[Thanks to Elena for pointing me to this discussion.]

My distribution is built from the precompiled binaries distribution at
gnu.org. I do make one modification, though, that _was_ important back
in the 21.x days when I started building a distribution.

Does freezing happen when you switch from Emacs to another application
and then back? I found out (can't remember how) way back that this
happens when no HOME environment variable is defined. That's why it is
automatically created by my installation wizard when the variable does
not previously exist.

That may do the trick.

In my case, it is not when Emacs regains focus but rather when one tries 
to perform an action: typing, saving, cutting text, and so forth. It 
does not appear to be limited to just keyboard initiated actions, since 
I experience the pauses when using the toolbar, too.

However, I didn't have a HOME environment variable set, so I gave that a 
try. It did not change my experience, but it was a great suggestion.

On that topic: vanilla Emacs/w32 (i.e. emacs.exe -q --no-site-file) says 
(expand-file-name "~") => "c:/Users/mdaniel/AppData/Roaming". Is there 
some good reason why it chooses AppData\Roaming instead of 
\Users\mdaniel like intuition would predict? This is not specific to 
Vista, BTW; on XP it thinks "C:\Documents and 
Settings\mdaniel\Application Data" is "~".

I will certainly give Vincent's custom distribution a whirl and see how 
that works out. Everyone needs an installation of LaTeX on their 
machine, anyway. :-)

Hi Eric (and list),

I'm bringing this discussion back to the mailing list so we can share 
this new information and search for a solution.

To bring the list up to speed, Eric is experiencing the same stutter on 
his machine that I experience. I asked if his machine was part of an 
active directory domain (which is the only thing I could think that was 
common between the two computers on which I experience this problem).

As you can see, his answer is yes, which is great because now we have 
something else to discuss.

What kind of experiments can we run to figure out what Emacs is trying 
to do?

Also, I wondered if perhaps this behavior was related to "tramp" since 
22.3 doesn't have tramp and also doesn't stutter (for Eric or myself).

   Any insight will be greatly appreciated!

Hello

I'm experiencing the same problem on a domain computer xp sp2 with
emacs 23.1.1 offical binary
I don't think it has anything to to with tramp
emacs22 also has tramp AFAIK

Yes, I remembered a few days ago that I have a problem with all 
MSYS/MinGW based programs, and M-x about-emacs shows it was built using 
MinGW. Here is the description of my symptoms with MSYS 
(https://sourceforge.net/tracker/?func=detail&atid=202435&aid=2077300&group_id=2435)

For example, as detailed in that link, launching rxvt.exe (which comes 
with MSYS) takes quite a few seconds. I don't know if it "stutters" the 
same way as Emacs because I am not typing as much in it; in fact, Emacs 
is the most interactive MSYS/MinGW application I have.

On the one hand, I'm sorry that blamed Emacs, but on the other hand 
since the Windows version of Emacs uses MSYS, this is relevant.

You could be right about MinGW. I've tried to find a emacs23 VC build, but
couldn't find anything... probably I will try to compile myself when I find
some time..

For the record, you don't need MSYS to build or run a MinGW build of Emacs.

Yes, I was researching yesterday and it turns out I was wrong. The 
content of http://mingw.org/wiki/MSYS states that MSYS is _not_ the 
subsystem, as I erroneously assumed it was. I thought MinGW
was a collection of compilers which targeted the MSYS runtime. The
content of http://mingw.org/wiki/MinGW claims that its compilers
target the Microsoft runtimes.

Having said that, learning this just makes me _more_ confused. Now I 
wonder if perhaps the mingw-gcc outputs are somehow not using the 
Microsoft runtimes "correctly", leading to some kind of initialization 
delay. [yes, I know this has really digressed into a MinGW discussion, 
and for that I am sorry]

I want very much to use Microsoft's compilers to build Emacs, in order
to find out what's wrong. However, for right now I don't have the
intellectual bandwidth to chase that.

   Sorry for the confusion,

I came to our HQ today and found out that the stutter ist not occuring when
I'm directly connected to the domain. I only have this problem when I'm
"offline" or connected with VPN.

I'm not sure, but it looks like emacs is trying to resolve something which
is failing when the domain is not properly connected.

I'm having the same problem on a windows xp sp 3 and I can confirm:
1/ Ctrl-g does not interrupt the pause
2/ Having a network connection corrects the problem

For me the pause only happens when I want to edit the buffer. If I
just move the cursor around, there is no pause. Continued editing does
not pause but if I wait a couple of minutes, I get a pause again.

As for point 2, I get the impression that any network connection
solves the problem but I'm having trouble confirming this because my
wifi cxn is very intermittent.

Does (setq w32-get-true-file-attributes nil) help?

This will stop Emacs from trying to look up the users and groups that
own files. My guess is that this is happening during auto-save, hence
after you make edits to the file, with a few minutes in between.

It seems to help at least while emacs is open... No pauses until now
with that setting.
Still problematic is starting and closing emacs... there the delay
still occurs even with -Q (although not every time)
Also note that I have turned off auto-save and backup.

Worked like a charm for me!! (I don't open/close emacs very often so
I've not noticed any pauses there).

Thanks for the help!!

Same here. Emacs pauses while saving files. I thought it was happening
whenever I had remote files opened, but it ended up not being like
that.

GNU Emacs 23.1.50.1 (powerpc-apple-darwin8.11.0, NS apple-
appkit-824.48)

I've been seeing this same problem for the last month since I compiled
and built emacs on my PowerBook G4 Mac + OS X 10.4.11.

The 'beachball' spins for a few seconds but then emacs works fine
immediately afterwards.
I *have*  tried Ctrl-G, but I don't think it helps: and I would not be
surprised... doesn't the beachball mean 'unresponsive'?

And it is annoyingly frequent :)

To add detail, I'd like to mention that in my case, while I haven't
noticed that this happens more often with C-x C-s.. Will keep an eye
out for this!
steps I use to compile:
0. cvs -z3 -d:pserver:anonymous@cvs.sv.gnu.org:/sources/emacs co emacs
1. ./configure --prefix /Applications/Emacs.app/Contents/MacOS --with-
ns --enable-ns-self-contained=yes --enable-cocoa-experimental-ctrl-
g=yes # NOT 'sure' that used the 'experimental-C-g' option on this
latest build!
2. edit Makefile to remove 'maybe-blessmail'
3. make bootstrap ; make ; sudo make install

I used to build Carbon Emacs up till a couple of months ago, and do
not recall this behaviour.
