Generator sometimes hangs up
----------------------------
Key: JRUBY-1553
URL: http://jira.codehaus.org/browse/JRUBY-1553
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1b1
Environment: Mac OS X 10.4, MacBook, Core Duo, 2GB RAM
Reporter: Kornelius Kalnbach
The Generator seems to have problems with big enumerations:
$ time jruby -rgenerator -e 'gen = Generator.new((0..100000)); gen.next while
gen.next?'
real 0m5.699s
$ time jruby -rgenerator -e 'gen = Generator.new((0..100000)); gen.next while
gen.next?'
^C
real 3m9.880s
It seems the bigger the number is, the more often jruby hangs up (process goes
to sleep.)
This also affects the bm_loop_generator benchmark from Ruby 1.9.
Since the problem doesn't arise always, I can't think of a test case yet.
