Description of problem: Fedora 21's gnome-terminal now has majorly broken the triple-clicking to select whole lines feature. When you triple-click it often selects two unrelated lines instead of just the one. In F19 it would sometimes get it wrong, but 90%+ of the time it would get it right. In F21 it gets it wrong at least half the time. My hunch is it is aggravated by the new line-wrap-redo-on-resize feature. Version-Release number of selected component (if applicable): gnome-terminal-3.14.2-2.fc21.x86_64 How reproducible: Always if you follow my instructions. 50%+ of the time if you just do it randomly during your work. Steps to Reproduce: 1. open a new gnome-terminal 2. triple-click the blank area of the top line where your prompt is, or even any blank line on the new blank term Actual results: line 1 + line 2 both selected Expected results: select just line 1 Additional info: I don't think it's a wm thing, but just in case, I'm using sawfish-1.11-1.fc21.x86_64 and xfce (4.10.1-7.fc21.x86_64).
Update: it appears that the bug only (always?) hits when you select the unfilled blank area of a line. If you triple-click on some text on the line then the bug does not happen. I hope this isn't a "feature", as I often select lines with barely any text on them by clicking the blank area just to the right of it. I find it easier to pinpoint. Besides, selecting the next line as well doesn't make any sense as a "feature". Interestingly, try these variations: launch gnome-terminal launch nano type (change \n to nl's): 1\n2\n\n\n\n3\n4\n triple-click (tc) on the "1" character, OK tc on the space (really a nl) to the right of the "1", OK tc on the space two spaces to the right of the "1", BUG tc on the first char space area of one of the blank lines, OK tc on the 2nd char space area of one of the blank lines, BUG tc and drag from a buggy area down and the moving-selection box always is one longer than where the mouse pointer is, BUG(!!!)

Those bugs look somewhat related, but not exact. Fixing those may fix this one too, maybe. New update on my bug: it's even buggier than I described: - in a text editor add lines like this: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa b c d eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee - tc anywhere on the a's, keep holding them button down, all is OK - while still dragging/holding, move mouse down over b line where there is empty space: your selection now includes all of a b *AND* c lines! BUG - repeat above, but this time move mouse down over b line where there is the b character (not over empty space), all is OK!
Last time I took a look at the code my impression was that it's probably not just a few off-by-ones, probably the whole highlight code should be thrown out and reimplemented :)
I just figured this one out too. I see I'm not the first one :/ You don't mean re-implemented, but restore the old implementation that worked fine.
Fixed upstream.
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. 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 EOL if it remains open with a Fedora 'version' of '21'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 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, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. 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.
