Description James 2010-06-04 12:52:17 UTC
Description of problem:
The editor component of Emacs windows seems to freeze periodically: text may not be edited or selected for around 10 seconds. I don't know yet what specifically triggers this (or exactly when it happens). Other elements of the UI (toolbar, menu, scrollbars) remain responsive. Nothing's showed up in ~/.xsession-errors.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Edit stuff.
2. Wait.

Comment 1 Karel Klíč 2010-06-04 13:02:19 UTC
does it freeze also when started using "emacs --no-init-file --no-site-file"?

It might be caused by semantic, but semantic is not started automatically.

Comment 2 Terje Røsten 2010-06-28 18:02:29 UTC
I also see this problem, home dirs on nfs, LDAP+sssd auth. 

James, do you have a local disk and/or local auth?


Comment 3 Terje Røsten 2010-07-07 17:54:59 UTC
More info from a local user, to trigger the freeze emacs should be running for a good while, then
suddenly the mini-buffer shows

 Removing duplicates ... done.

and the main window freeze. 

A way to wake up emacs again, is to try to visit a another file with C-x C-f, then emacs unfreeze
and the primary file can be worked on again. I don't think --no-init-file --no-site-file matters.

Comment 4 Josh Cogliati 2010-09-22 15:11:01 UTC
I get a bug like this commonly as well.  I didn't get the Removing duplicates message though.

Comment 5 Josh Cogliati 2010-09-22 16:27:09 UTC
It still occurs with:
emacs --no-init-file --no-site-file

To wake emacs up, I need to use the menu bar with the mouse.

Comment 6 Josh Cogliati 2010-12-03 17:16:35 UTC
I have the toolbar turned off, but I was running with it on one day, and I noticed that I get the same symptoms if the toolbar gets selected.  The keyboard input then switches between buttons in the toolbar, so it looks like the rest of emacs is frozen.

Comment 7 Josh Cogliati 2010-12-23 15:58:29 UTC
Here is how to replicate it:
Start up emacs in X11:

emacs --no-init-file --no-site-file

Click on the menubar right of the "Help"

Watch emacs freeze.

I was told that this bug is:
and is fixed in the version of emacs that will be 23.3.

Comment 9 Josh Cogliati 2011-03-29 18:36:18 UTC
This is fixed in the currently released emacs 23.3.  This bug could be fixed in Fedora by upgrading to that version of emacs.

Comment 10 Bug Zapper 2011-06-02 12:04:00 UTC
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '13'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 13's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 13 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 

Comment 11 Josh Cogliati 2011-06-02 12:17:50 UTC
This bug is definitely still in Fedora 14.  I think it is in Fedora 15 as well, since Fedora 15 is still using Emacs 23.2.  It is probably not in rawhide since rawhide is using Emacs 23.3.

Comment 12 Bug Zapper 2011-06-27 17:31:28 UTC
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.

Comment 13 James 2011-07-04 21:44:08 UTC
Reopening as it's in Fedora 15, emacs-23.2-19.fc15.x86_64. "ASSIGNED" is not an appropriate status, can someone reset it or should a new bug be filed?

Comment 14 Julius Smith 2011-08-09 06:38:59 UTC
I can affirm that it's biting frequently in Fedora 15 (emacs v23.2.1).  It looks like a stuck thread problem (for the editor pane) that seems to happen often when switching focus from the editor pane to the window frame by means other than selecting a menu item on the window frame (which reliably enables the mouse to switch focus back to the editor pane).  

I had an interesting instance just now in which I wanted to resize my window from half screen to full screen, and after the resize, the editor pane was not only frozen, but it was still wrapped at half screen.  When I selected a window-frame menu item, the text immediately then rewrapped to full-screen width.  Thus, the editor frame thread apparently never ran at all starting when the mouse selected the window frame for resizing by dragging to the top and releasing.

Could the 23.3 patch be applied to 23.2 to see if that fixes it?

Comment 15 Josh Cogliati 2011-08-10 02:10:08 UTC
I am curious, why can't Fedora 15 just get Emacs 23.3?

Comment 16 Akira TAGOH 2011-11-16 09:20:42 UTC
I'm not sure if I'm facing same problem because I can easily reproduce it on even 23.3 on f16 and interestingly it seems happens on GNOME only. at least it works fine on KDE say.

Steps to reproduce:
1. run emacs -q --no-site-file
2. press C-z to iconify
3. deiconify the emacs window from the dash

Comment 17 Akira TAGOH 2011-11-16 09:22:43 UTC
forgot to mention this: it still works if iconifying from the window manager, such as "minimize" from the window menu.

Comment 18 Akira TAGOH 2011-11-16 09:32:20 UTC
Hmm, maybe "freeze" isn't the right word here, because emacs still accepts the input. I can destroy it with C-x C-c say.

The patch would be too fragile I'm afaraid.

(In reply to comment #15)
> I am curious, why can't Fedora 15 just get Emacs 23.3?

I apologize for forgetting about this bug for such a long time.

It was too risky to include Emacs 23.3 to Fedora 15 back then, as new Emacs release usually brings some serious regression. However, no problems specific to Emacs 23.3 were discovered so far. I'm going to prepare an update to Fedora 15 shortly.

This seems to be bug #721183 - emacs window won't redraw until resize after iconify with ctrl-z and uniconify
