Bug #2379: Variable named "memory" is clobbered in templates
http://projects.reductivelabs.com/issues/2379
Author: Thomas Bellman
Status: Unreviewed
Priority: Normal
Assigned to:
Category: functions
Target version:
Complexity: Unknown
Affected version: 0.24.8
Keywords:
If I have a variable named $memory in my manifests, I can't
access that from templates. Instead I get some semi-random
number.
node default {
$memory = 4711
notice(inline_template("memory = <%= memory %>"))
}
This gives me the output
notice: Scope(Node[default]): memory = 105436
but the exact number varies between runs. It seems to stay at
approximately 100'000, though.
Other variable names work fine. If I rename it to $xmemory, it
works as expected. It isn't a clash with facter facts either,
because facter doesn't report any fact named "memory". Even if
it were, assignments inside the manifests override facts; if I
use $memorysize in the example above (which is a fact), I get
4711 as expected.
I tried to add some instrumentation to parser/templatewrapper.rb,
but couldn't find find anything interresting. method_missing()
isn't called for "memory", and result() doesn't call
instance_variable_set() with "memory". Likewise, binding.memory
doesn't exist. But my Ruby knowledge is fairly rudimentary, so
take that bit of debugging with a grain of salt.
This happens with at least 0.24.8 on CentOS 5.3, and a Git
snapshot of 0.25 (769c8aa71e5b4855662314f13b1197853cdc843a)
on Fedora 9.
