[ClusterLabs] Coming in Pacemaker 2.0.5: integer or floating-point comparisons for node attribute rules

[Ken Gaillot]

Hi all,

Here's another new feature coming in Pacemaker 2.0.5, expected at the
end of this year ...

Pacemaker has long had the ability to modify resource options and
constraints according to rules based on node attributes:

https://clusterlabs.org/pacemaker/doc/en-US/Pacemaker/2.0/html-single/Pacemaker_Explained/index.html#idm47160816617536

The node attributes have a "type" that defaults to "string" for
comparisons. It can also be "version" to compare like a software
version (3.2.0 > 3.1.19 for example).

The documentation also stated that the type could be "integer" to
compare numerically. However, no one must have used that, since the
configuration and code actually only accepted "number"!

In 2.0.5, not only are we fixing that, but you will be able to specify
"integer" for 64-bit integer comparisons or "number" for double-
precision floating-point comparisons.
