[users at bb.net] Slave Output to STDIO

[Jeremy Cornett]

Hi,

 

I'm running a bunch of Windows slaves, and I noticed that when I upgrade
from 0.8.7p1 to 0.8.12, the output on the stdio for a factory step was
rather jerky, whereas it used to be very smooth. It seems like the slave
queues up output and sends it over the master in chunks, or perhaps the
master just loads it into the stdio page through the waterfall in chunks
instead of character by character. I don't know which (probably the latter).
Is there any way to make this output smooth again?

 

Specifically, I have a VERY long running process (6+ hours) that displays a
status asterisk for its percentage done. Right now, BuildBot is timing out
the process after 6 hours because nothing is being displayed on the stdio (I
set the timeout on the step to 6 hours, I guess I could set it to a higher
value, but seems counterproductive to the problem being experienced - i.e. I
shouldn't have to do that). I have a sneaking suspicion that some little
asterisks are actually being output one by one by the process running on the
buildslave over the course of the 6 hours, but the master isn't displaying
them on the stdio page as it should. I say this because the other processes
that display asterisks for percentage done are actually displayed all at
once (no asterisks for a couple minutes, then display all 100 of them at
once), and hence is timing out the process when infact I think it is running
and displaying a little output. I could be totally off base with this, but I
am wondering if that's what is happening.
