Changed Code

Why view changed code?

Viewing changed code is a vital part of any code review. Browsing the diffs of a change lets one assess the impacts of the change in terms of affected items and severity. It also allows the developer to review his own changes to reassure before ending development that no debug statements or self-reminder comments have slipped in.

When you have an open change and you want to review for yourself the performed edits before ending development, you can type ant upload_diff on command line and browse the changed files from web interface on the detail form of your change. Prior to uploading diffs, all your edits are committed to VCS.

Changelogic redirects users to local ViewVC instance – a web application for browsing CVS/Subversion repository. To see code differences, ViewVC address must have been configured from VCS servers registry.

You can see a list of modified files on a change's details view's section “Modified files”:
