Subject: RE: [bitbake-devel][PATCH] bitbake: add --noreply-timeout option

Hi Richard,

It's not the bitbake server that takes more than 1 minute to start, it's that the 'updateConfig' command that takes more than 1 minute. From what I see, other commands finish quite fast except the actual building one.
The server was still usable, even after the second world build managed to start.

I'm not using any special configuration. All default values. I do have extra layers added, such as meta-openembedded/*, meta-virtualization, meta-browser, meta-security, meta-selinux, etc. Anyway, the task number of a world build is about 40000+.

In fact, what I really want to do is to set the timeout to be some large value on our autobuilders so that we can avoid this start-up timeout failure. If such patch is not suitable for the official bitbake, I'll make it a local patch until our autobuilders are configured more properly. Do you have any suggestion?

That's all the information and the background.

You're saying that the server can take over a minute to start up and this is considered acceptable?

What configuration is the other world build running with? I'd suggest the system is so overloaded it isn't useful any more and you should have pressure control enabled or other mechanisms to allow the system to function.

I'm not keen to make this any more configurable as 60s should be enough and if it isn't, there are different issues at play.

Having bitbake silently hang for minutes at a time isn't good for users and isn't good for CI either.
