      neoctl: make 'print ids' command display time of TIDs · d9dd39f0
      Iliya Manolov authored
      Currently, the command "neoctl [arguments] print ids" has the following output:
      
          last_oid = 0x...
          last_tid = 0x...
          last_ptid = ...
      
      or
      
          backup_tid = 0x...
          last_tid = 0x...
          last_ptid = ...
      
      depending on whether the cluster is in normal or backup mode.
      
      This is extremely unreadable since the admin is often interested in the time that corresponds to each tid. Now the output is:
      
          last_oid = 0x...
          last_tid = 0x... (yyyy-mm-dd hh:mm:ss.ssssss)
          last_ptid = ...
      
      or
      
          backup_tid = 0x... (yyyy-mm-dd hh:mm:ss.ssssss)
          last_tid = 0x... (yyyy-mm-dd hh:mm:ss.ssssss)
          last_ptid = ...

      Safer DB truncation, new 'truncate' ctl command · d3c8b76d
      Julien Muchembled authored
      With the previous commit, the request to truncate the DB was not stored
      persistently, which means that this operation was still vulnerable to the case
      where the master is restarted after some nodes, but not all, have already
      truncated. The master didn't have the information to fix this and the result
      was a DB partially truncated.
      
      -> On a Truncate packet, a storage node only stores the tid somewhere, to send
         it back to the master, which stays in RECOVERING state as long as any node
         has a different value than that of the node with the latest partition table.
      
      We also want to make sure that there is no unfinished data, because a user may
      truncate at a tid higher than a locked one.
      
      -> Truncation is now effective at the end on the VERIFYING phase, just before
         returning the last ids to the master.
      
      At last all nodes should be truncated, to avoid that an offline node comes back
      with a different history. Currently, this would not be an issue since
      replication is always restart from the beginning, but later we'd like they
      remember where they stopped to replicate.
      
      -> If a truncation is requested, the master waits for all nodes to be pending,
         even if it was previously started (the user can still force the cluster to
         start with neoctl). And any lost node during verification also causes the
         master to go back to recovery.
      
      Obviously, the protocol has been changed to split the LastIDs packet and
      introduce a new Recovery, since it does not make sense anymore to ask last ids
      during recovery.

      New feature to check that partitions are replicated properly · 04f72a4c
      Julien Muchembled authored
      This includes an API change of Node.isIdentified, which now tells whether
      identification packets have been exchanged or not.
      All handlers must be updated to implement '_acceptIdentification' instead of
      overriding EventHandler.acceptIdentification: this patch only does it for
      StorageOperationHandler

      Implementing ipv6 on neo · 0cdbf0ea
      Olivier Cros authored
      In order to synchronise neo with slapos, it has to work perfectly with ipv4
      and ipv6. This allows to integrate neo in erp5 and to prepare different buildout
      installations of neo.
      The protocol and connectors are no more generic but can now support IPv4 and
      IPv6 connections. We adopted a specific way of development which allow to
      easily add new protocols in the future.
