Fix post-review errors with --diff-only.
Review Request #1185 - Created Oct. 28, 2009 and submitted
If you run post-review with --diff-only, and there is an error, it is not handled properly. For example: Remove your post-review cookie, and then try to update an existing review with --diff-only, it will crash with a KeyError (instead of giving you a login prompt). (Note: looking at this diff does not display the whitespace changes, even if you click "Show Whitespace changes", which makes it a little hard to understand the change.)
Testing done against Perforce (using changesets). - Posted a new review. - Updated diff, (new diff displayed as expected). - Updated diff with cookies removed, (forced login and updated diff as expected). - Updated diff with --diff-only, (new diff displayed as expected). - Updated diff with --diff-only with cookies removed, (forced login and updated diff as expected).
