Commit graph cache incorrectly propagates exception

XMLWordPrintable

      An internal message is reported incorrectly as an exception the stash logs when loading the browse branches page under the following conditions:

      • there is no commit graph cache for the repository
      • building the commit graph takes longer than the time permitted for rendering

      This is a logging only problem and does not effect the performance of Stash.

      The log error appears as:

      Exception in thread "CachedCommitGraphSource:thread-1" com.atlassian.stash.exception.ServerException: Unexpected IOException traversing commit graph for XXX/xxx[2]
