Hello,
According to the docs for v3.1.2 and v3.1.1:
https://bird.nic.cz/doc/bird-3.1.2.html#global-opts
*Thread setup*
[..]
Thread groups are configured by writing thread group /name /{} blocks, which
contain
the following options:
threads /number/
default /bool/
/[...]/
It also notes the following:
There is also a "simple" thread group setting. If you write *threads */number/
on top level, it is equivalent to
setting the worker group thread count to that number, and the express group
thread count to one.
This setting is deprecated and may disappear in some future version.
So.. now I come to setting up a new server, I thought I'd better try to use this
"new" config style. But whatever I try doesn't seem to work. I've tried various
iterations of:
thread group worker {
threads 1;
}
--> <FATAL> /etc/bird/bird.conf:55:10 No default thread group configured
thread group worker {
default;
threads 1;
}
--> <FATAL> /etc/bird/bird.conf:43:2 syntax error, unexpected THREADS,
expecting '}'
thread group worker {
threads 1;
default yes;
}
--> <FATAL> /etc/bird/bird.conf:43:2 syntax error, unexpected DEFAULT,
expecting '}'
thread group worker {
threads 1;
default;
}
--> <FATAL> /etc/bird/bird.conf:43:2 syntax error, unexpected DEFAULT,
expecting '}'
Weirdly, if I configure only "default;" with no other options, it accepts the
config:
thread group worker {
default;
}
root@rc01:/# /usr/local/sbin/bird -c /etc/bird/bird.conf -p
root@rc01:/#
If I add the (deprecated) top-level "threads", it complains I've got them both
configured:
threads 1;
thread group worker {
default;
threads 1;
}
--> <FATAL> /etc/bird/bird.conf:41:14 Mixing of `threads NUM` and `threads
worker {}` is not allowed.
As soon as I try any other config options, it doesn't accept it:
thread group worker {
default;
wakeup time 31415 s;
}
--> <FATAL> /etc/bird/bird.conf:43:2 syntax error, unexpected WAKEUP, expecting
'}'
Also tried:
thread group {
worker {
threads 1;
default;
};
}
---
- nope.
thread group worker {
threads 1;
}
thread group express {
threads 1;
}
--> <FATAL> /etc/bird/bird.conf:45:14 syntax error, unexpected EXPRESS,
expecting CF_SYM_KNOWN or CF_SYM_UNDEFINED
---
thread group worker {
threads 2;
default;
}
--> <FATAL> /etc/bird/bird.conf:43:2 syntax error, unexpected DEFAULT,
expecting '}'
---
thread worker {
threads 2;
default;
}
--> <FATAL> /etc/bird/bird.conf:41:8 syntax error, unexpected CF_SYM_UNDEFINED,
expecting GROUP
So, it seems the "default" option must be present, but if I add /any /other
option,
it doesn't accept it. Oddly, if I put another option before default, it doesn't
complain
about that, but instead complains about "default" being there.
I tried various 3.x versions 3.1.1, 3.1.2 and a couple of recent branches from
git repo.
As for the config - I just have the default bird.conf which ships with the BIRD
debian package, and I've added the thread group option somewhere near the top.
Any hints on the correct config would be appreciated. Or is this maybe a bug?
Thanks!
Rob
