Description Omair Majid 2015-11-24 19:45:43 UTC 
Linux bash prompt becomes invisible with jline2 1.12.

This is the upstream bug: https://github.com/jline/jline2/issues/163

This is breaking the terminal for programs that are using jline, such as Thermostat. When such a program using jline2 exits, it somehow disables echo in the terminal, making the terminal (apparently) unusable for further interaction.

As a workaround, both `stty sane` and `reset` fix the terminal.

Please consider rebasing this package or backporting the bugfix(es).
Comment 1 Severin Gehwolf 2015-11-25 09:24:19 UTC 
Re-assigning component as jline2 is jline since a while.
Comment 2 Severin Gehwolf 2015-11-25 09:43:32 UTC 
Please consider upgrading to 2.13:

Scratch build with the patch:
http://koji.fedoraproject.org/koji/taskinfo?taskID=11977256

If nobody objects I'll push this update in a day or two to rawhide.
Comment 5 Mat Booth 2015-11-25 18:27:32 UTC 
No objection here :-)
Comment 6 Severin Gehwolf 2015-11-26 19:19:21 UTC 
Pushed and built in rawhide[1]. I wonder if it's safe to backport this to F23. Any opinions?

I would take advantage of Koschei - wait and see if jline 2.13 doesn't break anything in f24. Then it should be fairly safe to push this to f23.

Good idea, thanks! Since I didn't see any failures in rawhide due to the jline update I went ahead and built it for F23 too.

Comment 11 Severin Gehwolf 2015-12-09 09:33:11 UTC 
FWIW, I've seen a similar issue with a failed maven build (used "mvn clean package" on a maven project that doesn't compile). After the build failure the terminal was not echoing chars any more.
