I believe the problem is that the ‘help’ subcommand object does not fully configure the other subcommand object (‘start’, in this case) before asking it to print its help info. Copying a few lines of initialization code from cli.py to help.py seems to fix this. Please see the bottom of this email for a diff / patch file that fixes the bug (at least on my system, so far).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I just started using StarCluster, and I *<b>love</b>* it. Thank you so much for creating this. I was absolutely giddy in describing it to a co-worker this morning, and it’s really helping me get my research done quickly and cheaply. The option to use spot instances as workers is especially brilliant. I hope this little patch helps out in some small way.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Best,<br>Ian<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Below is (1) the crash log, and (2) the patch to fix it.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>---------- CRASH DETAILS ----------<o:p></o:p></p><p class=MsoNormal>COMMAND: starcluster help start<o:p></o:p></p><p class=MsoNormal>2013-02-28 10:54:44,162 PID: 12056 config.py:551 - DEBUG - Loading config<o:p></o:p></p><p class=MsoNormal>2013-02-28 10:54:44,162 PID: 12056 config.py:118 - DEBUG - Loading file: /home/grb/.starcluster/config<o:p></o:p></p><p class=MsoNormal>2013-02-28 10:54:44,164 PID: 12056 cli.py:287 - DEBUG - Traceback (most recent call last):<o:p></o:p></p><p class=MsoNormal> File "/home/grb/starclust/venv/local/lib/python2.7/site-packages/StarCluster-0.93.3-py2.7.egg/starcluster/cli.py", line 255, in main<o:p></o:p></p><p class=MsoNormal> sc.execute(args)<o:p></o:p></p><p class=MsoNormal> File "/home/grb/starclust/venv/local/lib/python2.7/site-packages/StarCluster-0.93.3-py2.7.egg/starcluster/commands/help.py", line 21, in execute<o:p></o:p></p><p class=MsoNormal> sc.addopts(lparser)<o:p></o:p></p><p class=MsoNormal> File "/home/grb/starclust/venv/local/lib/python2.7/site-packages/StarCluster-0.93.3-py2.7.egg/starcluster/commands/start.py", line 39, in addopts<o:p></o:p></p><p class=MsoNormal> if self.cfg:<o:p></o:p></p><p class=MsoNormal> File "/home/grb/starclust/venv/local/lib/python2.7/site-packages/StarCluster-0.93.3-py2.7.egg/starcluster/commands/base.py", line 77, in cfg<o:p></o:p></p><p class=MsoNormal> self._cfg = self.goptions_dict.get('CONFIG')<o:p></o:p></p><p class=MsoNormal> File "/home/grb/starclust/venv/local/lib/python2.7/site-packages/StarCluster-0.93.3-py2.7.egg/starcluster/commands/base.py", line 46, in goptions_dict<o:p></o:p></p><p class=MsoNormal> return dict(self.gopts.__dict__)<o:p></o:p></p><p class=MsoNormal>AttributeError: 'NoneType' object has no attribute '__dict__'<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>---------- SYSTEM INFO ----------<o:p></o:p></p><p class=MsoNormal>StarCluster: 0.93.3<o:p></o:p></p><p class=MsoNormal>Python: 2.7.2+ (default, Oct 4 2011, 20:06:09) [GCC 4.6.1]<o:p></o:p></p><p class=MsoNormal>Platform: Linux-3.0.0-12-generic-x86_64-with-LinuxMint-12-lisa<o:p></o:p></p><p class=MsoNormal>boto: 2.3.0<o:p></o:p></p><p class=MsoNormal>ssh: 1.7.13<o:p></o:p></p><p class=MsoNormal>Crypto: 2.3<o:p></o:p></p><p class=MsoNormal>jinja2: 2.6<o:p></o:p></p><p class=MsoNormal>decorator: 3.3.1<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>--- help.py.orig 2013-02-28 11:03:22.863318498 -0500<o:p></o:p></p><p class=MsoNormal>+++ help.py 2013-02-28 11:04:13.287884893 -0500<o:p></o:p></p><p class=MsoNormal>@@ -17,6 +17,10 @@<o:p></o:p></p><p class=MsoNormal> try:<o:p></o:p></p><p class=MsoNormal> sc = self.subcmds_map[cmdname]<o:p></o:p></p><p class=MsoNormal> lparser = optparse.OptionParser(sc.__doc__.strip())<o:p></o:p></p><p class=MsoNormal>+ sc.gopts = self.gopts<o:p></o:p></p><p class=MsoNormal>+ sc.parser = lparser<o:p></o:p></p><p class=MsoNormal>+ sc.gparser = self.gparser<o:p></o:p></p><p class=MsoNormal>+ sc.subcmds_map = self.subcmds_map<o:p></o:p></p><p class=MsoNormal> if hasattr(sc, 'addopts'):<o:p></o:p></p><p class=MsoNormal> sc.addopts(lparser)<o:p></o:p></p><p class=MsoNormal> lparser.print_help()<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>---<o:p></o:p></p><p class=MsoNormal>Ian W.
