Because the tab is flashing, I click on it to switch to it, expecting to see an error message shown that explains why it is flashing, but as soon as I switch to it, it stops flashing.
Here are screenshots that alternate and form the "flash". How do I find out exactly what AT is trying to bring my attention to?
Generally, that means that a 'bell' sound (control g) has been issued on a tab that's not the selected tab. You hear 'bells' all the time in the terminal, you may not have noticed. For example, if you backspace everything in your shell prompt and keep hitting backspaces, you'll get hear a BELL that says 'stop hitting backspace, I can't back up any more', etc...
Servers can use that in any number of ways to get your attention.... But what happens when you have a dozen tabs open and your hear a BELL??? How can you tell which tab it came from? Enter the flashing yellow triangle... A BELL happened here. There may be something on the screen you need to see.
Now... What I can't do is tell you why the server sent you the bell. That's very server and application specific. Ideally it would accompany some kind of text on the screen that would explain.
If it happens often, you could try trapping a debug log for me to take a look at, and maybe we figure out why....
File->OpenLog on a tab that may BELL
Tab away.
File->CloseLog after you see the yellow triangle
zip the logfile and email it to me
Perhaps that will yield some insights.
It's also possible it could be part of a malformed escape sequence from the server or even possibly a sequence I'm not recognizing correctly. Logfile should tell me.
aha... i do know what you mean by bells and why they get generated, i just (apparently) have the audio turned off within AT. there is no message when i switch to the tab. and if i switch away from it, the tab again starts flashing. so under what circumstances is the flashing tab suppose to stop flashing?
right now, that tab is flashing because it doesn't have focus. if i click on it, it stops flashing, just now i hit ENTER several times, then switched to another tab, and the flashing continues. i can generate a log but i need to figure out a consistent way to duplicate it, and right now i can't even get it to stop flashing. 🙁
Yes, it is normal for a bell to set the yellow triangle. Visiting the tab should turn it off however, since you've 'acknowledge' it....
I have noticed the behavior you describe at least once, where the bell persists, but also can't replicate it at will.
Let me take another deep dive.
Still can't reproduce it. I'm going to need a logfile. File->OpenLog and File->CloseLog around a session that does this.
I'm not able to reproduce it either.
Finally found this one. A side effect of a new feature implemented in 13.17. Should now be fixed in RC9
