bug#11021: 23.4; Text client hangs when region is highlighted in another frame with mouse

[Phil Brooke]

Hi,

The problem: Highlighting some text in an X frame using the mouse appears 
to cause text clients to freeze until the region is deactivated.

Replicating the problem:

    I started a freshly-built version of emacs 23.4 with
      ./emacs -q
    Inside emacs, I started a server:
      M-x server-start

    I now write some text into the *scratch* buffer (of an X frame) and
    highlight it with the mouse (hold mouse button 1, sweep across text,
    release button 1).

    In another xterm, I run
      ./emacsclient -t
    The text mode client appears to freeze until I return to the original
    frame and press C-g, type some text or other actions to cause the
    highlighting to disappear.  Any input I typed into the text client is
    handled at this point.

    While emacsclient -t is running, if I now highlight some text with the
    mouse in a frame again, it causes the text mode client to freeze.

Other X frames are unaffected, e.g., emacsclient -c brings up a frame;
that frame is not frozen as for emacsclient -t.

The problem does not occur if I use C-space and the cursor keys to
highlight some text in the X frame instead of using the mouse.

If I have two emacsclients running (both -t) and one sets highlights a
region, the other emacsclient does not appear to freeze.

Some output from emacs-report-bug follows (the test machine isn't
configured for sending email directly, so I cut'n'pasted it to a
different machine):

Hello.

I can't repeat this on the latest trunk.  Can you confirm that it does not happen on the trunk?

Thanks,

On two different systems, I see it in 23.4 (and 23.1...) but not with
the current trunk, so it looks like it is fixed.

I agree; I can't replicate it on the latest trunk.

Thanks,

Could it be that the bug is only hidden by the fact that the
region/clipboard/selection has a different default behavior in 24?

Which variable(s) would I need to change in 24 to revert the behaviour to 
23's default for testing?

Thanks,

I tried the old settings from NEWS; no bug.

*** To return to the previous behavior, do the following:
**** Change `select-active-regions' to nil.
**** Change `mouse-drag-copy-region' to t.
**** Change `x-select-enable-primary' to t (on X only).
**** Change `x-select-enable-clipboard' to nil.
**** Bind `mouse-yank-at-click' to mouse-2.
