pylint: disable the similarities checker
This is a very slow checker, estimated to be O(n²) by its author; sousing it all the time is not good. It can be re-enabled on the commandline via “--disable-checker=”.

LUDiagnoseOS._DiagnoseByOS: remove unused arg
The node_list argument to _DiagnoseByOS is not used, and is obsoleted bythe fact that the rlist argument already has the valid nodes as keys(assuming RPC behaviour didn't change). Thus, we remove it and silence...
daemons: handle arguments correctly and uniformly
Of all daemons, only rapi did abort when given argument. None of ourdaemons use any arguments, but they accepted them blindly. This is avery bad experience for the user.
This patch adds checking and exiting in all daemons, in a uniform way....
hv_xen/_GetConfigFileDiskData: remove unused arg
The disk template is not needed, all that's used is the disk data. Assuch, remove this parameter from the function.

jqueue/_CheckRpcResult: log the whole operation
Currently only the rpc call, but not its description (which also showsthe argument) is logged. We change this to log failmsg too, and thisalso silences a warning.
Optparse extenders have to obey a given API
So we just silence the warning.
backend._OSOndiskAPIVersion: remove obsolete arg
The 'name' argument is not used anymore, probably since before 2.0.Since this is an internal function, we can just remove it (from itscaller too).
pylint cleanups: dangerous initializers
Plus a silence for a wrong "uninitialized var".
Convert to static methods (where appropriate)
Many methods are simple pure functions, and not depending on the objectstate. We convert these to staticmethods.
Remove more unused variables
This removes unused variables in the rest of the code (outside lib/).
Add targeted pylint disables
This patch should have only:
- pylint disables- docstring changes- whitespace changes
burnin: move decorators out of classes
Similar to commit c881c5, we move the decorators out of classes, suchthat they become simple functions instead of methods. This more clean,since only the wrapped functions need to be methods/have access to‘self’....
Rename an ConfdInotifyEventHandler init argument
'file' is a builtin keyword/type. Like many others, it should not beused as a variable/argument name.
No code is actually passing in this argument so renaming it is simple.
Introduce a makefile lint rule
This runs pylint over all the python files. Yes, it takes a long while,but it's the only way to properly analyze the source codes as only inthis way pylint can see all uses of the various modules/classes/etc.
Implement all hv functions in hv_chroot/hv_fake
The chroot and fake hypervisors were missing:
- the powercycle node functionality- proper handling of migration requests
The powercycle was just used as in the other hypervisors (use thestandard linux powercycle). The migration for chroot was disabled...
Update the _autoconf.py make rule for pylint
This adds targeted pylint disables, but since _autoconf.py isautogenerated we need to do this in Makefile.am (hence the separatepatch).
Disable TODO warnings in pylint
We don't get any useful out of this - a git grep is as effective, andthese only pollute the pylint output.
Add some stubs to bdev.FileStorage
This patch adds explicit errors (instead of notimplemented) inFileStorage (and the associated TODOs).
Fix indentation issues
Fix two bugs in ConfigWriter._EnsureUUID
Wrong argument name and wrong number of arguments in string formatting.
KVM: Abstract/rework instance up checks
This patch abstract the check "is instance stopped" into a separatefunction, and thus simplifies a couple of higher-level functions. Italso moves from manual read of the pidfile to use the (correctabstraction of) _InstancePidAlive....
KVM: Split out the pidfile computation
In some cases we only need the pidfile, but not the pid or the alivestatus.
Fix an error message
Detected by an 'Unused variable' warning.
Remove many 'Unused variable' warnings
Note there are some cases left which need extra cleanup.
Fix use of the logging functions
The logging functions expand the arguments themselves, thus it's saferto let them do it rather than manual string formatting.
Also re-wraps one comment.
Merge branch 'devel-2.0' into devel-2.1
Add targetted pylint disables
This patch adds targeted pylint disables, where it makes sense (eitherdue to limitations in pylint or due to historical usage), and also a fewblanket ones in rapi where all the names are… “different”.
Update pylintrc
Since the current pylintrc is in now way good for our style, we updateit:
- remove docstring checks, since we have too many cases where a docstring doesn't make sense- relax naming rules to cover more alternatives (but not break the naming rules)...
Fix two bugs in seldom-used codepaths
New version of pylint, new bugs found!

This removes/updates some module-wide pylint disables.
Implement BuildHooksEnv for NoHooksLU
This just adds a stub function that raises an assertion error; thisaccomplishes two things:
- silences many pylint warnings- if we ever stumble upon this, a specific assertion error is (hopefully) clearer than just a not implemented error...
Fix indentation in hv_kvm
Per pylint warnings.
Partial cherry-pick of 6c881c5 from the 2.1 branch
This cherry-picks the utils.FieldSet.Matches changes and the significantjqueue.py change. These are stable in the 2.1 branch and therefore makesense to backport to 2.0 (are basically cleanups).
Add a release script
Currently releases are done via the manual procedure onhttp://code.google.com/p/ganeti/wiki/ReleaseProcess, but that is notvery reliable, and breaks for rc releases. The 1.2.9/2.0.5/2.1.0~rc2releases were done with this new script that eases the process....

burnin: add --no-name-check support
This patch modifies burnin to accept the --no-name-check option and alsoadds --no-ip-check (which was always set to True before).
CreateInstance: allow no ip check with start mode
Since gnt-instance start doesn't do any checks on the IP, it doesn'tmake much sense to do so in instance create (with start) if the userexpressly passes in ‘--no-ip-check’. Removing this requirement eases the...
Command line/RAPI support for --no-name-check
This patch adds --no-name-check to gnt-instance add and gnt-backupimport. This is opposite to the opcode parameter (name_check) as it issimilar to ip_check and start.
It also adds it to RAPI and gnt-instance batch-create as a parameter in...

It also adds a CheckArguments to LUCreateInstance and changes the...
Pass --fqdn to ssh hostname checks
The cluster verify checks for fqdn are done via address lookups, andthere we actually use the FQDN. However, for the ssh hostname checkwhich is done at node add time, we rely on the default of the “hostname”command. And Debian for example recently changed the default to return...

Security issue: add validation of script names

Improve LUQueryNodes for lockless case
In most uses of LUQueryNodes, we don't take a lock. This means that theinstance data is not protected across GetInstanceList andGetInstanceInfo, and this can lead to instances not existing anymore.
Switching to GetAllInstanceInfo means that we get a single,...
Add disk cache control parameter for KVM
This patch adds the 'cache' parameter for KVM; currently this is onlycustomisable at the hypervisor level, so it's the same for all drives(except any CDROM image, which gets the default).

DRBD: ignore unreadable meta devices
The DRBD driver can ignore dead disks but not dead meta devices (forwhich it refuses to configure the minor). To handle this case, we checkthat the meta device is readable and if not we ignore it (the same aswhen backend._RecursiveAssembleBD didn't find it)....
Simplify utils.ReadFile
