Re: [OE-core] Crazy display

[Stephen Arnold]

I do mostly remote screen sessions (on gentoo host, sometimes
ubuntu/debian vm) and occasional local terminal (xfce term but remote
could be console only).  The fact that I have not seen this once is
just *weird* (and I'm pretty damn good about hitting the annoying
bits).

I just wanted to check particularly with Gary and Ross - since the following

Paul did fix some progress bar issues which were one cause of this.
pseudo is another cause and we've not gotten to the bottom of the
pseudo issue :(. It writes to the console unknown to knotty so there
isn't much we can do about it from the bitbake side, it should be a)
making it clear the messages come from psuedo and b) likely going to a
logfile, not the main console.

This seems to be related to
https://bugzilla.yoctoproject.org/show_bug.cgi?id=10024.
I get this issue after it prints "Child process exit status 4:
lock_held" and then that message is overridden by the task status with
the progress bar duplicated down one line.

Same for me.
I'm running build in a standard Gnome terminal on Ubuntu and have seen 
it popping up suddenly during a build.
I also have the notion that it happens when the machine is very busy / 
low on memory.

Seems to happen at various points during the build. Looks like bad
timing of console updates so can happen at any point, I'd see evidence
its happened multiple times in a given build.


This is bizarre. Clearly something is different between your systems and mine

I've also seen it on a standard linux ssh session to a remote machine,
no screen, no tmux, just ssh from a gnome-terminal window to a remote.
I've not spotted what the pattern is, other than it seems to be
something about the console write timing being off and started around
the time of the progress changes.

Cheers,

Richard

I understand some people are seeing this issue with the progress bar, but so 
far I haven't observed any problems here - any help reproducing it would be 
much appreciated. The bugzilla entry is:

  https://bugzilla.yoctoproject.org/show_bug.cgi?id=10046

Are you guys perhaps using the same terminal application? Using screen / tmux

[OE-core] Crazy display

[Gary Thomas]

I haven't seen this before, just thought I'd toss it out there.
I was doing a build (actually three in parallel in separate
windows on my build box) and noticed this:

Currently  3 running tasks (3282 of 5081)  64% |### 
   |

0: busybox-1.24.1-r0 do_compile (pid 29425)

2: unifdef-native-2.11-r0 do_populate_lic (pid 24548)

Somehow the task tracker (that does a nice job of telling the user
what's going on without being overwhelming BTW) got very confused!

I doubt if I can every repeat this, just passing on the observation!
