      Fix compatibility with DRBD 8.3 · 01e2ce3a
      Iustin Pop authored
      
      
      DRBD 8.3 changes two more things compared to 8.2:
        - /proc/drbd format changed in multiple ways; the part we're
          interested is the ‘st:’ to ‘ro:‘ change (in the changelog named as
          “Renamed 'state' to 'role'”
        - “drbdsetup /dev/drbdN show” changed the ‘device’ stanza from:
            device "/dev/drbd0";
          to:
            device                  minor 0;
      
      This patch fixes these both and adds data files and unittests for DRBD
      8.3.1.

      Convert IOErrors for /proc/drbd into our errors · f6eaed12
      Iustin Pop authored
      If /proc/drbd can't be opened, this raises an IOError, but all the
      error-handling behaviour in backend treats only BlockDeviceErrors. This
      creates a plain failure in cluster verify and in other RPC calls.
      
      This patch simply converts EnvironmentErrors into BlockDeviceErrors, and
      also changes the RPC result for NV_DRBDLIST and its handling to be able
      to show the error. The other RPC calls work by default now, due the
      existing error handling.

      Apply the right permissions to /etc/hosts · 9b977740
      Guido Trotter authored
      In the current Ganeti version when modifying /etc/hosts we mistakenly
      give it the permissions of the temporary file we create to define its
      content, which is by default 0600. This breaks most non-root
      applications, and thus must be corrected. This patch forces the mode to
      be 0644 (but we might decide to just use the mode of the previous
      /etc/hosts, if we want to be more polite against any eventual
      administrative choice). We also add a new assertFileMode() method for
      unit tests and actually check in the SetEtcHostsEntry and
      RemoveEtcHostsEntry tests that the mode is correct, to be sure not to
      reintroduce this bug again. Also, a FIXME is added in the original
      functions stating that it would be nice to use WriteFile+fn() rather
      than reimplementing its functionality again.

      Instance parameters: force typing · a5728081
      Guido Trotter authored
      We want all the hv/be parameters to have a known type, rather than a
      random mix of empty string, boolean values, and None, so we declare the
      type of each variable and we enforce/convert it.
      
      - Add some new constants for enforceable value types
      - Add new constants dicts HVS_PARAMETER_TYPES and BES_PARAMETER_TYPES
        holding not only the valid parameters but also their types
      - Drop the old HVS_PARAMETERS and BES_PARAMETERS constants and calculate
        the values from the type dict
      - Convert all the default parameters to a valid type value
      - Create a new ForceDictType utils function, to check/enforce a dict's
        element value types, with relevant unit tests
      - Drop a few custom functions to check/convert the BE param types in
        utils and cli, in favor of ForceDictType
      - Double-check the parameter types using ForceDictType in both scripts
        and LogicalUnits, when possible.
      
      As a bonus:
      - Remove some old commented-out code in gnt-instance
      - Remove some already fixed FIXME
      - Fix a bug which prevented VALUE_DEFAULT to be applied to BE parameters
        in SetInstanceParams because the value was checked for validity before
        that transformation was made
      - Fix a bug which prevented initing a cluster and passing hvparams to
        work at all
      - ForceDictType allows an allowed_values for exceptions, which makes us
        able to do the checking even when some values must not be
        converted/typechecked (for example the 'default' string in
        SetInstanceParameters)

      Introduce more configuration consistency checks · 4a89c54a
      Iustin Pop authored
      This patch enhances the duplicate DRBD minors checks (currently just a
      few) and adds automatic checks of configuration consistency at
      configuration file writing time.
      
      In order to do so and show meaningful error messages, the
      _UnlockedComputeDRBDMap function is changed to not raise errors in case
      of duplicates, but instead return both the minors map and the duplicate
      list, and its callers now raise the error. This allows the VerifyConfig
      function to return a complete list of duplicates.
      
      The new checks required some small updates to the unittests for the
      config module.

      Enable auto-unit formatting in script output · 9fbfbb7b
      Iustin Pop authored
      This patch enables by default the old 'human-readable' option, but in a
      slightly different model.
      
      The option is now called "units" and takes either:
       - 'h' for automatic formatting
       - 'm', 'g' or 't' for mebi/gibi/tebibytes
      
      If 'h' is used, we add a unit suffix, otherwise nothing is added so that
      parsing is easy.
      
      The default value of this unit is:
        - 'h' if a separator is not passed
        - 'm' if a separator is passed

      Convert the locking unittests to repetition-test · 4607c978
      Iustin Pop authored
      Currently the locking tests are using timeouts to ensure an event will
      'never happen'. However, this is suboptimal.
      
      The patch converts all of these to instead: not wait, but sequence the
      operations logically and expect that they execute as such. In case of
      not so, they will timeout with a big (60s) timeout.
      
      The 'never happen' is tested by multiple repetitions of the same test -
      this is not perfect, but again 'X will never happen' is not actually
      testable.
      
      This patch reduces the runtime of the tests from ~5.4 to ~0.8 seconds
      (with 8 repetitions of each test thas has 'never happen' situations).

      So, instead of any timeouts for synchronization, we move to actual

      instead we rely on the fact that when a process is cleaned up, its FDs

      There are a few RPC calls that are made outside of the LU code, and
