Release notes for version 5.17/09-PROOF.00

N.B. These changes are in addition to those described in the release notes for version 5.17.05-PROOF.00

• Improvements
  • Enable the usage of TTreeCache; can be switched-off setting ProofPlayer.UseTreeCache: no in the relevant rootrc file (or using the xpd.putrc directive)
  • Add possibility for the admin to broadcast a message to the connected users: TProofMgr::SendMsgToUser("message or text file","user");
  • Add a new directory 'proof' under tutorials with a frame to run PROOF tutorials and an example of non-data driven selector making some drawings.
  • Improve notification during Reset
  • Enable standard Scalla/Xrootd if-else-fi constructs (previous 'if' condition at the end of the directive still supported but deprecated; a warning message is printed when they are found)
• Bug fixes
  • XrdProofdProtocol:
    • Fix a problem in CleanuProofServ sometimes preventing proper cleanup
    • In ReadBuffer, do not trigger an error on empty files
    • Add missing protection against an empty string while setting the ROOT version
    • Reduce default timeout on admin requests and make it configurable
    • Additional check on the ownership of the unix socket
    • Fix a flexibility problem with the multi-master setup * XrdProofdManager: define the mist of unique nodes to avoid broadcasting twice to the same node
  • XrdProofWorker: improve matching technique
  • TProof: add setter and getter for Int_t parameter
  • TProofServ:
    • Avoid deleting a query result twice in some special cases
    • Fix a problem with the initialization of fKeptQueries
    • Do not flush the log file in SendAsynMessage: this recent change made the logs "disappear" form the ProgressDialog
    • Read session.rootrc with level kEnvChange to be able to change existing settings
  • TXProofServ: do not disable the socket in Terminate
  • TApplication: remove duplication (left over of a merge)
  • TPacketizerUnit: fix a problem with filling the histof for PerfStats
  • TProofPlayer: call Begin() also during selecter re-initialization
  • XROOTD:
    • Several fixes in the clients (mostly missing protections).
