Marios Andreou updated DTACLOUD-248:
------------------------------------
Attachment: 0001-Addresses-JIRA-DTACLOUD_248-frozen-string-1.8-vs-1.9.patch
Attached patch should fix this.
Another 1.8 vs 1.9 compatibility issue:
[marios@name deltacloud]$ ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [i386-linux]
[marios@name deltacloud]$ irb
irb(main):001:0> s = "api[provider]=eu-west-1".freeze
=> "api[provider]=eu-west-1"
irb(main):002:0> s.gsub!(/;([^\/]*)/, '')
=> nil
marios@name deltacloud]$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]
[marios@name deltacloud]$ irb
1.9.2p290 :001 > s = "api[provider]=eu-west-1".freeze
=> "api[provider]=eu-west-1"
1.9.2p290 :002 > s.gsub!(/;([^\/]*)/, '')
RuntimeError: can't modify frozen string
from (irb):2:in `gsub!'
from (irb):2
from /home/marios/.rvm/rubies/ruby-1.9.2-p290/bin/irb
Explanation seems to be that in 1.8, gsub will not fail on a frozen string if
the gsub operation doesn't actually modify the string. In 1.9 gsub on frozen
string will explode either way... relevant:
