Class and module names could be cached
--------------------------------------
Key: JRUBY-6218
URL: https://jira.codehaus.org/browse/JRUBY-6218
Project: JRuby
Issue Type: Improvement
Components: Core Classes/Modules
Affects Versions: JRuby 1.7
Reporter: Charles Oliver Nutter
Priority: Minor
During the 1.7 dev cycle, I removed caching of module and class names due to
the complexity of supporting their updates when classes and modules enclosing
them have their names updated. Specifically, I could not find an efficient way
for a class contained within an anonymous class to get a new, non-anonymous
name when the anonymous container gains a name later on.
As a result, the performance of Class#name and Module#name has degraded in the
1.7 dev branch (master).
We could potentially still compensate for this degradation with a new form of
caching. I have made such an attempt and posted it here:
https://gist.github.com/1372628
I use the constant cache invalidation as a way to know that somewhere, some
name has been updated. It does not pass tests, but I think it's possible for us
to fix it.
