I’m writing some new code and using #!/usr/bin/ruby -w as the bang line in the script. The code looks like: require ‘rubygems’ require ‘net/ldap’ filter = Net::LDAP::Filter.eq( “key”,“value” ) ldap.search (:base =\>treebase, :filter =\> filter) I get: /usr/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ldap/filter.rb:310: warning: ambiguous first argument; put parentheses or even spaces /usr/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ldap/filter.rb:311: warning: ambiguous first argument; put parentheses or even spaces /usr/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ldap/filter.rb:324: warning: ambiguous first argument; put parentheses or even spaces /usr/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ldap/filter.rb:338: warning: ambiguous first argument; put parentheses or even spaces /usr/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ldap/filter.rb:356: warning: ambiguous first argument; put parentheses or even spaces /usr/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ldap/filter.rb:358: warning: ambiguous first argument; put parentheses or even spaces /usr/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ldap/filter.rb:360: warning: ambiguous first argument; put parentheses or even spaces These warnings occurs after the filter line but before the search line. This looks like it is at the lines that have: scanner.scan What needs to be done to make those warnings go away? Mike B. ---

Never saw that in any of my testing. What version of Ruby are you using? I’ve patched the code in Rubyforge. Sync to the latest and see if the problem goes away. Come to think of it, I don’t like this very much. There should have been no warnings. The code path you’re looking at is a recursive descent parser, and it got touched a few days ago. If you’re feeling frisky, would you please get version 0.0.3 of Net::LDAP and see if you get the same problem? Perhaps a regression crept into 0.0.4. ---

Umm… any feedback, Barjunk? If this is not a real problem, I want to rollback the code changes I made. ---

Also, they occur in a code path that is not exercised by your code sample. Can you send me a whole program that exhibits the flaw? (Private email is fine.) ---

Sorry for the late response…I only get digests and have been busy on a project. I will update to the latest and see what happens. Mike B. ---

I outsmarted myself- I thought about -w (which barjunk mentioned) but instead of testing it the easy way, I added $VERBOSE=true to my test script, and that didn’t produce any warnings. The current version in Rubyforge SVN does not give the warnings. I’ll hold off another release for a few days in case anything else turns up. ---

I don’t have an svn client at the moment and not going to be able to (time wise) be able to get to that any time soon…if you can build a gem for me, I’ll be able to test it easily. Sorry about that.

Sorry about that. I think the ML bounced it. I emailed it to your private email.
