24.4.1; Triple-clicking selects and deselects the line in weird situations |
|

Hello!
We came across a weird behavior in Emacs.
The graphical version (in X) will select a line if the mouse is
triple-clicked. Under certain situations, it will select but immediately
deselect the line again.
Reproduction:
Triple-click on any line in any buffer. Notice that Emacs selects the
whole line, and leaves it selected.
Evaluate the following code.
(defun repro-filter (fun beg end delete)
(let ((string (funcall fun beg end delete)))
(with-temp-buffer
(insert "."))
string))
(with-current-buffer (get-buffer-create "*Bug*")
(set (make-local-variable 'filter-buffer-substring-functions)
'(repro-filter))
(insert "Hello, World!\n")
(pop-to-buffer (current-buffer)))
Triple-click on the "World" in the *Bug* buffer. Notice that Emacs
selects the whole line only momentarily, and then deselects it again
immediately.
I expected the line to stay selected like without this piece of code.
This bug was not present in 24.3.
Regards,
Jorgen

Since it fixes Jorgen's test case I installed the patch into master, and
I'm closing this bug.

If/when you find another recipe to reproduce your problem, just make
a new bug report (or re-open this one).
Thank you,
Stefan
