When a build is cancelled for whatever reason and re-started, the svn changes that triggered the cancelled build are nowhere in the job's changelog pane (http://<hostname>:8080/view/Server/job/<job name>/changes).
This means that looking at the jobs changelogs does not show all changes, only those that contributed to a successful build. The earlier changes that triggered the cancelled build are skipped and completely absent from the jenkins changelog.
It should show all changes, including those for cancelled builds as well. Currently there is no changelog.xml in the cancelled build's directory.
I don't care whether the changes are shown as part of the next successful build vs in the changelog for cancelled builds. They just need to be visible somewhere. There should not be dropped changes in the log just because a build did not complete.
