[bitbake-devel] [PATCH 0/2] Add maximum task accounting

[Mark Hatle]

On my own machine, a 192 thread machine, if I start a new project without
a local download cache, I end of DoSing my machine.  I wanted a way to
create a maximum number of tasks, of any given type, so that I could limit
the number of concurrent do_fetch commands.

The first patch is a cleanup, while it's not required for the task accounting
I did discover that a few operations were happening in the wrong order --
this could cause a problem if anyone is trying to use the RunQueueStats in
new ways.

The second patch is the one that actually implements the max-task limits.
As noted in the comment, while theoretically you could set this in a recipe,
the behavior will be unpredictable, it's meant to be set in the global
configuration space, i.e. the local.conf.

I've been using these patches successfully for the path few months.
