About the Store Diff Setting

Store diff info means that FishEye is caching the summary of what lines are added and removed between subsequent versions of the same file in its database. In other words, we are storing the info of a diff, not the diff itself (thus you will still be able to view diffs if this value is set to off).

After setting this value to on, a full re-index of your repository is required so that FishEye can collect diff info for all revisions in your repository.

Turning 'Store Diff Info' on and off

To find this setting, open the FishEye Admininistration Screen, then click 'Repository List' under 'Repository Settings'.

For the desired repository, click 'View'. The 'View Repository' screen opens. In the section labelled 'Repository Details', click 'Edit Details'. The 'Edit Repository Details' screen opens.

In the 'Edit Repository Details' screen, 'Store Diff Info' is a value that can be toggled on or off. On is the default setting for new repositories.

Considerations for the Store Diff Info Setting

Required for Per-author Line Graphs

Leaving this option off will disable per-author line graphs.

Required for Displaying Context of Search Results

Leaving this option off will disable the display of context of found terms in search results.

Re-index Required for Per-author Line Graphs

Diff info is always stored for CVS repositories. Note that a full re-index is required to enable per author charts after upgrading from FishEye 1.4.3 or earlier.

Perforce Repository Indexing Performance Impact

Turning 'Store Diff Info' on for Perforce repositories requires FishEye to make extra requests to your depot in order to collect the diffs. This may substantially increase the time it takes to scan your repository.

Repositories created before FishEye 1.5 will default to 'Store Diff Info' off.

CVS and Subversion repository scan times are not affected by this setting.
