#460 closed defect (fixed)

cp -rv fails rather gracelessly in face of network quake

Description (last modified by robk)

c.f. #459

when a long running cp -rv hits a network quake (e.g. laptop is taken to a different network locale) one of the copies fails, but the error reported stems from within the node, and hence the exception propagated back up is a '500 internal server error' containing verbatim the source of a nevow rendered exception. this is perhaps not the most suitable way to report a problem on the command line.

furthermore when using the 'tahoe' cli from the mac .app bundle, the error appears in a dialogue box which fills the screen.

  • Description modified (diff)

capture of the output of cli 'tahoe cp -rv'

the break after the first few lines indicates the point of the network quake:
