Nedit bugs: paste and server crash

Nedit bugs: paste and server crash

[mathog]

Hi,

I am using Cygwin/X Xserver with nedit from a remote client.  Most of 
the time
it works but there are 3 bugs that have been getting on my nerves 
enough so that
I now want to track them down.  Is there a prepackaged debug version of 
the X11 server
that I can load (for the 3rd problem below)?  I don't want to have to 
assemble a
complete build environment for cygwin just for this one problem?

These are the three problems with this configuration:

1.  Cut from a windows application, paste into a nedit window. Works 
99.8% of the
time - until it doesn't.  This one is likely going to be horrible to 
figure out since
it only shows up intermittently. Once it goes bad it locks up nedit 
(does not respond to mouse
or keyboard input) for seconds to minutes, and then it "comes alive" 
again.  Once this
happens subsequent pastes also tend to lock.  The only way to 
completely clear this
situation seems to be to shut down nedit and X11, then restart X11 and 
then nedit.  Very inconvenient.
This message appears on the terminal that started nedit:

XmClipboardInquireLength() failed: clipboard locked.

I have never seen a similar paste error when using Nedit on the console 
of remote workstation.  Due
to the length of time it takes to appear, that may be just a 
statistical effect, since
I never work there for 4 hours at a time, as I do normally with Cygwin 
X11 and the remote
nedit.  It is my impression that one factor that helps to trigger this 
bug is when the
"cut" paste remains highlighted in the original windows application - 
but it is inconvenient
to do "select text", "cut", "deselect text"  then "paste", as the 3rd 
step is not
normally required.


2.  In long editing sessions (hours) draw errors tend to accumulate in 
nedit.
For instance, the "save as" dialog will come up with none of the 
buttons (like save!)
visible.  Other times divots will appear on parts of the screen outside 
of the text
editing region, and/or parts of the pull down menu list will disappear. 
Possibly
related to the preceding bug since, again, it only shows up 
intermittently and after
long periods.

3.  The X11 server will crash, taking all sessions from various 
machines,
with nedit or not, with it.  I do not recall the log file containing 
anything
useful, for instance, a backtrace from the point of the crash.

Details:

Cygwin/X Xserver package version 1.11.1-1 built 2011-10-05

Nedit from Ubuntu 12.04.1 LTS.  That nedit package is:

1:5.6~cvs20081118-7

and ldd shows that it is linked ot /usr/lib/libXm.so.2 which is
the one from lesstif2 (1:0.95.2-1), even though libmotif4 
(2.3.3-5ubuntu) is
installed (so libXm.so.4 is present as well).

Connection is over ssh using putty.

Here is the log file from such a crash.  There is nothing in it that I 
find useful, perhaps
it means something to one of you:

Regarding the 1777 warning about /tmp/.X11-unix, that file (as seen in 
Mingw) has
protection flags 755 and is owned by the same program running the X11 
server and
putty.  (Unclear to me what 1777 means on Windows XP + Cygwin, since 
Windows does not
have the 1000 protection bit like Unix does.)

This version is notably old.  I might suggest that you update to the
latest and retest before spending much time looking into the code for the
problem.  You may luck out. :-)

The xorg-server-debuginfo package contains detached symbols and source code
which should enable you to debug the X server.

If you can still reproduce your crash with the current version of X server,
then please post a backtrace.

> Cygwin/X Xserver package version 1.11.1-1 built 2011-10-05

This is quite old, and I have definitely fixed some clipboard related bugs
since then.

Please don't send mail to me, send it to the list.

You can always upload a large attachment somewhere and include a link in your
mail.

These redraw bugs are possibly in lesstif or nedit, if that is the only
application you see this problem with.  You might find that starting the
Xserver with the +bs option helps in case like this.

Nedit bugs: paste and server crash

[mathog]

[Apologies if this is a duplicate post.  The first one did not come 
back through the mailing
list, even though a reply to it did.]

Hi,

I am using Cygwin/X Xserver with nedit from a remote client.  Most of 
the time
it works but there are 3 bugs that have been getting on my nerves 
enough so that
I now want to track them down.  Is there a prepackaged debug version of 
the X11 server
that I can load (for the 3rd problem below)?  I don't want to have to 
assemble a
complete build environment for cygwin just for this one problem?

These are the three problems with this configuration:

1.  Cut from a windows application, paste into a nedit window. Works 
99.8% of the
time - until it doesn't.  This one is likely going to be horrible to 
figure out since
it only shows up intermittently. Once it goes bad it locks up nedit 
(does not respond to mouse
or keyboard input) for seconds to minutes, and then it "comes alive" 
again.  Once this
happens subsequent pastes also tend to lock.  The only way to 
completely clear this
situation seems to be to shut down nedit and X11, then restart X11 and 
then nedit.  Very inconvenient.
This message appears on the terminal that started nedit:

XmClipboardInquireLength() failed: clipboard locked.

I have never seen a similar paste error when using Nedit on the console 
of remote workstation.  Due
