[Bug 1190183] Re: bzr diff always returns error exit code (1) even when it succeeds

[Matthew Paul Thomas]

I wasn't disputing that adding a file was a change. I just thought that any non-zero exit value was supposed to communicate an error, 1 especially so (EXIT_FAILURE). But on further reading, I see it's more complicated than that.

Sorry for the noise.

Title:
  bzr diff always returns error exit code (1) even when it succeeds

Status in “bzr” package in Ubuntu:
  Invalid

Bug description:
  Bazaar 2.6.0dev3, bzr 2.6.0~bzr6571-4ubuntu2, Ubuntu 13.04

   😌 11:14:12 at hacking> bzr init test
  Created a standalone tree (format: 2a)                                         
   😌 11:14:20 at hacking> cd test
   😌 11:14:49 at test> touch foo
   😌 11:14:55 at test> bzr add
  adding foo
   😌 11:14:58 at test> bzr diff
  === added file 'foo'
   😠 11:15:01 at test> echo $?
  1
   😌 11:15:05 at test> 

  What should happen: If the bzr diff command succeeds, it should return
  an exit code of 0, not 1.
