I notice this problem in xemacs 21.4 patch 22 running in linux in -nw
mode. It does not happen in xemacs 21.4 patch 8 (also linux, nw).
I mark a region and then try some command like untabify or sort lines
and get a complaint that the region is not active.
Judging by the
(setf zmacs-regions nil) solves the problem.
Interestingly, setting it back to t then leaves me in a state where
the problem does not occur.
Perhaps I did something to enter this weird state?
I wonder what. And how I can tell.

First, tell us, are these built by you from source, or are they
packaged from a Linux distribution?
Next, try to reproduce the problem with xemacs -nw -vanilla. (If it
doesn't, it's not really our problem -- we can't fix it -- but we'll
try to help find workarounds and suggest fixes.) If at all possible
find a reliable recipe. If xemacs -nw -vanilla does not produce the
problem, we'll need to know what the contents of your custom and init
files are, as well as the "default" and "site-start" libraries.
For example, in XEmacs 21.4.22 on Macintosh I cannot reproduce with
"xemacs -nw -vanilla" followed immediately by C-x h M-x sort-lines
RET.
How do you mark the region? Ie, do you use the mouse with GPM, C-SPC,
Shift-arrowkey, or one of the mark-OBJECT commands such as mark-buffer
== C-x h? Does it matter how you mark the region? Is the region
visibly active (ie, highlighted)? Does it matter what mode(s) you are
using?
Perhaps I did something to enter this weird state?
Given that simply setting and resetting zmacs-regions seems to help,
that's our first guess, but XEmacs should not surprise you this way.
If it's a side effect of something you did, that should either be
better documented or perhaps the side effect can be eliminated.
I wonder what. And how I can tell.
If you notice an error that might be a bug, immediately doing C-h l
will give you your most recent hundred or so keystrokes as well as the
contents of the " *Message Log*" buffer. That will tell you what
you've done recently.

First, tell us, are these built by you from source, or are they
packaged from a Linux distribution?
This machine runs CentOS release 5.4
According to my notes there was no yum package available and I ended
up doing this:
2010-02-13
wget ftp.xemacs.org/pub/xemacs/stable/xemacs-21.4.22.tar.gz
gzip -dc xemacs-21.4.22.tar.gz | tar xf -
cd xemacs-21.4.22
./configure
make install
wget ftp.xemacs.org/pub/xemacs/packages/xemacs-mule-sumo.tar.gz
mv xemacs-mule-sumo.tar.gz /root/
cd /usr/local/lib/xemacs/
gunzip /root/xemacs-mule-sumo.tar.gz
tar xf /root/xemacs-mule-sumo.tar
cd
wget ftp.xemacs.org/pub/xemacs/packages/xemacs-all-packages.tar.gz
gunzip xemacs-all-packages.tar.gz
cd /usr/local/lib/xemacs/
tar xf /root/xemacs-all-packages.tar
I started a new terminal, ran xemacs -nw again and did not see the
same behavior. So I must have done something to put it into this
strange mode. But I can't figure out what.
The interesting thing I saw was that after marking the region I would
see the region highlighted, and then I'd type m-x and after typing
one more character, the s for sort lines or the u for untabify, the
highlighting would disappear. Is that a useful hint?
As it turns out, this is the first time I've seen this particular
problem, but there's another one that I've seen a lot and I'd be even
more interested in finding out how to fix. This one happens on many
different machines. Again I don't know how I get into this mode.
I'm in a dired buffer.
I type f to go to a buffer.
I see in the minibuffer "Failing I-search backward: f".
I type c-g and get a backtrace buffer:
Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)
isearch-top-state()
isearch-pop-state()
#<compiled-function nil "...(33)" [isearch-invalid-regexp isearch-opoint
isea$
call-interactively(isearch-abort)
As long as I leave that backtrace buffer I can then go back to the
dired and type f and get to the buffer. When I type q to get out of
the backtrace I'm back in the same state.
Also in that state I seem to be in the middle of a search, so that
when I type c-s it's as if I've already typed a bunch of text.
How do you mark the region?
I only know one way to do it, which
is c-space and then move.
This is in an xterm where I've run ssh to talk to another machine and
inside that ssh I've done xemacs -nw.
Given that simply setting and resetting zmacs-regions seems to help,
What should/could be different between the original state and the
result of setting and resetting zmacs-regions?
that's our first guess, but XEmacs should not surprise you this
way.
If it's a side effect of something you did, that should either be
better documented or perhaps the side effect can be eliminated.

If you notice an error that might be a bug, immediately doing C-h l
will give you your most recent hundred or so keystrokes as well as the
contents of the " *Message Log*" buffer. That will tell you what
you've done recently.
I've actually increased the number stored to 10000 in
most of my
xemacs's. That affects (recent-keys ) though help - l still only
shows 100.

Hi,
when reading the code several month ago, got the impression there are
circulars and redundant things in it.

If you are able to use the EPEL repository, there's an xemacs-21.5.29
package in there. I might admit, under duress, that I had something
to do with its creation. (I am not the current maintainer of it, but
it's close enough to the Fedora version, which I do maintain, that I
can probably answer questions about it.)
