1.7.35

• removed the "optimization" (a.k.a. reduction of index segments to 1) step at the end of indexing
  • improves indexer performance
  • one can still perform this operation using the --reduceSegmentCount indexer option
    • Lucene documentation recommends this is only done for indexes that are to be archived and made read-only
    • the option might go away in the future (to be replaced with tunables for Lucene segment merging)
• the Docker image now has SSH client
  • so the repositories can have ssh:// URI
    • one has to make sure the SSH authentication works in the container
• usename/password is now configurable on project level
  • this is currently used only for Subversion repositories
  • the Subversion related environment variables were removed
• thread names now have common prefix
  • this is useful for debugging or observing indexer/webapp (e.g. via jstack or such)
• avoid reopening index directory for various operations
  • should improve performance of the webapp a bit
