Description Darren Hart 2011-11-29 15:05:00 UTC

When do_patch requires user input, the build will just appear to hang if a screen terminal is used. With devshell you'll see a log message telling you to connect to the screen session, something like that would make it clear that no more progress will be made until some user intervention occurs.

Comment 1 Richard Purdie 2011-12-01 15:42:50 UTC

This is a bit of a puzzle since they call the same code which both output the same warning:

NOTE: Executing RunQueue Tasks
NOTE: Running task 10 of 10 (ID: 1, /media/build1/poky/meta/recipes-extended/bash/bash_4.2.bb, do_patch)
NOTE: package bash-4.2-r1: task do_patch: Started
WARNING: Screen started. Please connect in another terminal with "screen -r devshell"

Any further tips to reproduce?

Oh boy. I suppose it's possible that with BB_NUMBER_THREADS=24 that I just lost this message in the noise. I suspect that is the case. Suggest closing as not a bug unless anyone else has observed this behavior.

I'll go for WORKSFORME. If anyone does run into it they can reopen this.
