helloworld-20100607-1042-fdsk7h87.log

A plain ssh run of swift fails in current trunk. Remote execution, say from
bridled to pads, through ssh (no coasters, pbs, etc., though adding them in
doesn't change output) causes the ssh connection to hang, causing swift to loop
indefinitely producing the following output:

 [arjun at bridled ~]$ swift -sites.file .swift/sites.xml -tc.file .swift/tc.data
helloworld.swift
 Swift svn swift-r3258 cog-r2726

 RunID: 20100607-1042-fdsk7h87
 Progress:
 Progress:  Initializing site shared directory:1
 Progress:  Initializing site shared directory:1
 Progress:  Initializing site shared directory:1


The only log file produced is the basic log file for the run
(helloworld-20100607-*.log, full log attached) that halts at the following
section of output:

2010-06-07 10:42:03,061-0500 INFO  SshPrivateKeyFile Parsing private key file

This lead me to suspect the private key pass, etc., but all check out. The
private key still functions for interactive ssh logins, and the password is
correct. Setting the auth.defaults file's host.password setting to something
different produces an exception as expected.

It's also important to note that no further log files are produced. There's
nothing created (not even the folder) in the work directory. There are no
scripts added in .globus/scripts. There are no files added to
helloworld-20100607-*.d/. Swift hangs and infinite loops, perpetually adding
lines of "Progress:  Initializing site shared directory:1" into stdout.

This behavior does not exist in the swift-0.9 release, where the script runs
perfectly without issues, locally and remotely via SSH.

sites.xml:
  <pool handle="pads">
    <filesystem url="login1.pads.ci.uchicago.edu" provider="ssh"/>
    <execution url="login1.pads.ci.uchicago.edu" provider="ssh"/>
    <workdirectory >/home/arjun</workdirectory>
    <profile namespace="karajan" key="jobThrottle">0</profile>
  </pool>

Let me know if anyone can confirm.
