      Get rid of the default_hypervisor slot · 066f465d
      Guido Trotter authored
      
      
      Currently we have both a default_hypervisor and an enabled_hypervisors
      list. The former is only settable at cluster init time, while the latter
      can be changed with cluster modify.
      
      This becomes cumbersome in a few ways: at cluster init time for example
      if we pass in a list of enabled hypervisors which doesn't include the
      "default" xen-pvm one, we're also forced to pass a default hypervisor,
      or an error will be reported. It is also currently possible to disable
      the default hypervisor in cluster-modify (with unknown results).
      
      In order to avoid this we get rid of this field altogether, and define
      the "first" enabled hypervisor as the default one. This allows ease of
      changing which one is the default, and at the same time maintains
      coherency.
      
      At configuration upgrade we make sure that the old default is first in
      the list, so that 2.0 cluster defaults are preserved.

      Export more instance information in hooks · 67fc3042
      Iustin Pop authored
      
      
      Currently we miss in hooks the instance's hypervisor, hypervisor
      parameters and backend parameters. This forces hooks to query back into
      ganeti, which is dangerous due to possible luxi sockets exhaustion.
      
      This patch adds these three as INSTANCE_HYPERVISOR, INSTANCE_HV_*,
      INSTANCE_BE_*. The hook environment prefixes all keys with “GANETI”, so
      a default settings for a xen-pvm instance would be:
      
        GANETI_INSTANCE_HV_initrd_path=
        GANETI_INSTANCE_HV_kernel_args=ro
        GANETI_INSTANCE_HV_kernel_path=/boot/vmlinuz-2.6-xenU
        GANETI_INSTANCE_HV_root_path=/dev/sda1
      
      Any dashes in parameter names are changed to underscores, since
      variables with dashes are not easy to access from the shell
      (alternatively we could deny those via an unittest for constants.py).

      Fix the SafeEncoding behaviour · d392fa34
      Iustin Pop authored
      
      
      Currently we have bad behaviour in SafeEncode:
        - binary strings are actually not handled correctly (ahem)
        - the encoding is not stable, due to use of string_escape
      
      For this reason, we replace the use of string_escape with part of the
      code of string escape (PyString_Repr in Objects/stringobject.c); we
      don't escape backslashes or single quotes, since that is that makes it
      nonstable. Furthermore, we only use the encode('ascii', ...) for unicode
      inputs.
      
      The patch also adds unittests for the function that test basic
      behaviour.

      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.
