Should notify when build fails
Fedora has patched gnome-terminal to present a desktop notification when a command has completed. When I used JHBuild, I always received a notification immediately after my build succeeded or failed, so I could take appropriate action. I relied on this for productivity.
With BuildStream, there is no notification when the build fails. (I think there is a notification when it succeeds.) I'm absentminded and find that I often do not notice a build has failed until much later, sometimes hours later. Since BuildStream presents its own failure prompt to allow the user to choose what action to take, perhaps BuildStream should manually create notifications. But there's a difficultly here: notifying would be undesirable if BuildStream is running in a currently-focused terminal. So maybe integration with gnome-terminal, and investigation of how exactly the terminal notifications work, will be required. Debarshi Ray is the expert on this.
