      Replace license symbols with {{{ }}}-enclosed license blocks. · 6df609a9
      Eric Eide authored
      This commit is intended to makes the license status of Emulab and
      ProtoGENI source files more clear.  It replaces license symbols like
      "EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
      blocks that contain actual license statements.
      
      This change was driven by the fact that today, most people acquire and
      track Emulab and ProtoGENI sources via git.
      
      Before the Emulab source code was kept in git, the Flux Research Group
      at the University of Utah would roll distributions by making tar
      files.  As part of that process, the Flux Group would replace the
      license symbols in the source files with actual license statements.
      
      When the Flux Group moved to git, people outside of the group started
      to see the source files with the "unexpanded" symbols.  This meant
      that people acquired source files without actual license statements in
      them.  All the relevant files had Utah *copyright* statements in them,
      but without the expanded *license* statements, the licensing status of
      the source files was unclear.
      
      This commit is intended to clear up that confusion.
      
      Most Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the Affero GNU General Public License, version 3
      (AGPLv3).
      
      Most Utah-copyrighted files related to ProtoGENI are distributed under
      the terms of the GENI Public License, which is a BSD-like open-source
      license.
      
      Some Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the GNU Lesser General Public License, version 2.1
      (LGPL).

      Some very basic infrastructure for generalized tools was added. · 639758e6
      Dan Gebhardt authored
      Some parts very "hacky", lots of XXX / TODOs.
      BARELY tested!!!! Don't use on the production system yet.
      Need to verify that things didn't break, especially with the automanager,
      the bgmon.pl "outage detection stuff", etc...
      
      See code's todos and also the file
      flexlab-canonicalization-misc-notes.txe
      
      At this point:
       - mangerclient & automanagerclient did not change.
       - The manager, when a probe request is received, looks at the DB table
         "tool_spec" to retrieve the proper wrapperpath, formal parameter list, etc..
       - The manager assembles a message and sends it out to the appropriate
         path probers, which operate on the request as they have been
         (no major internal changes to the path probers).
       - The path probers call the toolwrapper to run the tests
       - The toolwrappers return a canonical result for that type of metric.
       - The path probers send the result and the actual parameters used by the
         tool to the data collector.
       - The data collector uses the toolname and actual parameters to get an
         idx number. This idx is stored in the "measured_by" field of this
         measurement's entry in the "pair_data" table.

      Updates for better handling of getstatus failures
      1 - libwanetmon.pm/sendcmd: tcp timeout is changed from 1 sec to 3 sec
      2 - Now we remove a node from measurement only if it fails two consecutive
          attempts (currently a getstatus probe happens every half an hour).
          Though if there exists multiple nodes at a single site, it can
          switch over to other node after a single getstatus failure.

      First update after an architectural change: · 53fcb773
      Dan Gebhardt authored
      - managerclients send their measurement request commands to the manager
        through the event system.
      - the automanagerclient sends its measurement requests to the manager
        using TCP.
      - The manager is the only entity to send measurement requests to the bgmons
        running on the nodes.
      - A queuing system on each bgmon orders requests based on test frequency,
        so that the fastest frequncy measurement is used.
