[FishEye Knowledge Base]
When FishEye indexes a CVS respository, it synthesizes a changeset identifier to group file-level changes into a single consistent changeset. The grouping is described in this FAQ: How does FishEye calculate CVS changesets?.
Changeset ancestry was added in FishEye 2.6. Changeset ancestry refers to the linking of a changeset to a preceding/parent changeset(s). This allows you to view the development progress of your repository using the Commit Graph (see Viewing the Commit Graph for a Repository).
For CVS respositories, changeset ancestry is implemented, as follows:
This approach ensures that a branch, whose first change is to a file which is very old, is not considered to have been branched at the time that file was last changed. It is considered to be branched at the last change to the repository instead.
