Issue #3013 has been updated by Ricky Zhou.

A few comments on the patch:

Why was exit replaced with exit!?  Previously, the use of exit! caused a bug 
where the output from the "puts detail" was lost because stdout was not flushed 
with exit!.  I mentioned a case where this previously showed up in comment 11 
on ticket #2731.

Also, the second exit after the begin block should probably be exit(1), or 
maybe even something akin to assert(false) in ruby, since things are definitely 
not right if execution gets past that block (in fact, is it even possible at 
all)?

One last thing - the += in the /proc/mounts code should probably be changed to 
<<, since that doesn't create a new string for each iteration of the loop.

Bug #3013: util.rb:execute broken on Ruby <1.8.3
http://projects.reductivelabs.com/issues/3013

Author: Ricky Zhou
Status: Ready for Testing
Priority: Urgent
Assigned to: Markus Roberts
Category: exec
Target version: 0.25.3
Affected version: 0.25.2
Keywords: 
Branch: http://github.com/MarkusQ/puppet/tree/ticket/0.25.x/3013


Apparently the patch in ticket #2731 introduced one more issue by using 
readpartial, which isn't available until ruby 1.8.3 (RHEL4 at least is 
affected).  I'm not sure how this is normally handled in ruby, but if the 
readpartial function is not available, the code should fall back to sysread 
(along with some code for handling EINTR).

Anybody with better ruby knowledge know how this should be done?
