Certain BuildSteps (well, ShellCommand at least, thanks to ticket #43) allow you pass a WithProperties object as workdir. FileUpload and FileDownload do not.
Here's my example:
workdir = shell.WithProperties("build.%s", "buildnumber")
...
f2 = factory.BuildFactory()
f2.addStep(transfer.FileUpload(
slavesrc="file",
masterdest="uploaded-file",
workdir=workdir,
))
When I run the build in question, the upload step dies with this exception:
