Having an issue with win32-service, it works on most 2003 servers I’ve  
tried, but on several, it segfaults.

Platform: Windows Server 2003, Standard Edition Build 3790 Service Pack  
2, I have other servers of the same level and they work fine.

require ‘rubygems’  
require ‘win32/service’  
require ‘win32ole’

include Win32

host = ‘mps-bes1’

Service.services( host, “” ){ |s|  
puts s.display\_name  
puts “”  
}

Ideas?

That’s odd. Line 1100 is actually pure Ruby code:

binary\_path = binary\_path.unpack(‘Z\*’)[0]

I wonder if you’ve found a bug.

A few questions.

What version of Ruby are you running?  
One click or hand built?  
What version of win32-service?  
Does it always segfault at the same place?

If it does segfault at the same place, can you open up your services  
explorer window and see what the next one on the list is?

Control Panel -\> Administrative Tools -\> Services

Or, if you could step through the debugger, I’d love to see what the  
‘binary\_path’ variable is set to when it dies.

Regards,

Dan

More information is needed for debugging this bug.  
What’s the output of sc.exe ?

sc.exe \mps-bes1 query

One-click install, installed win32-service via gem install command just  
a few days ago. version 0.6.1-x86-mswin32-60.

W:\>ruby -v  
ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]

BlackBerry MDS Connection Service is the next service in the list.

Yes, it consistently stops exactly same place, even if the “puts  
s.display\_name” line is commented out.

Yesterday in testing different things, it seg faulted and listed  
string.rb as the culprit. I can’t duplicate that today.

Installing ruby-debug, new territory for me. I will post value of  
‘binary\_path’ variable soon.

Oddly enough, from a Vista box it, the same _exact_ script (against  
mps-bes1 also) goes past that service and gets near the end until it  
crashes in the same fashion.

I inserted “puts binary\_path” on line 1101 in services.rb.

If I change line 1101 to “puts binary\_path.inspect”, the script  
completes without error.
