Review Request #681 — Created Dec. 27, 2008 and submitted
|Review Board SVN (deprecated)|
Fairly frequently (at least at VMware), people try to create a review request from the web UI by entering a changeset number that has no associated open files. In these cases, we get a KeyError for 'depotFile' when attempting to get the change description from the Perforce Python API. This change adds a check and an exception to show an error on the field instead of just sending a traceback to my email and dropping them back on the form.
Ran scmtools unit tests.
