[Buildbot-devel] addStep ShellCommand echo into a file

[john gale]

I'm trying to create a buildStep which echo's a simple pathname into a  
file.

Mac OS 10.5

class UpdateTOTPath(ShellCommand):
     def start(self):
         bname = self.getProperty("buildername")
         bnumber = self.getProperty("buildnumber")
         brevision = self.getProperty("got_revision")
         self.setCommand(["echo", "/apache/docs/builds/build-%s-r%s-b 
%s.tgz" % (bname, brevision, bnumber), ">", "archive/%s.txt" % (bname)])
         ShellCommand.start(self)
...
f_build1.addStep(UpdateTOTPath())


Yet this doesn't seem to be working.  It's as if the build command has  
usurped standard out and is not letting it get into the file at all.   
In the log for this build step, we see the command:

echo /apache/docs/builds/build-syncbot1-r18356-b34.tgz > archive/ 
syncbot1.txt
in dir /build/build (timeout 1200 secs)
watching logfiles {}
argv: ['echo', '/apache/docs/builds/build-syncbot1-r18356-b34.tgz',  
'>', 'archive/syncbot1.txt']

But then the standard out for the buildstep is what should have gone  
into the file:

/apache/docs/builds/build-syncbot1-r18356-b34.tgz > archive/syncbot1.txt

and the file itself is empty.

Is there a way we can succeed in piping into a file through a buildStep?

thanks,

	~ john
