Fix SshRunner breakage from the changed API
More places actually use the SshRunner than just the gnt-clustercommands.

Change SshRunner usage
Currently the SshRunner uses a SimpleConfigReader instance, however thisis not best. We change it to use the cluster name directly (and itsconstructor now takes this as parameter, instead of SCR), and itscallers are change to pass the name directly....

Add new query to get cluster config values
This can be used to retrieve certain cluster config values fromwithin clients.
OpDumpClusterConfig was not used anywhere, hence I'm just reusingit. The way ConfigWriter.DumpConfig returned the configurationwas not thread-safe, anyway (no deepcopy)....
Move functions from ssconf.py elsewhere
These functions will be used to access config values instead of usingssconf.
Add simple configuration reader/writer classes
This will be used to read the configuration file in the node daemon.The write functionality is needed for master failover.
Remove last use of utils.RunCmd from the watcher
The watcher has one last use of ganeti commands as opposed to sendingrequests via luxi. The patch changes this to use the cli functions.
The patch also has two other changes: - fix the docstring for OpVerifyDisks (found out while converting...
Add cluster options from ssconf to configuration
ssconf will become write-only from ganeti-masterd's point of view,therefore all settings in there need to go into the main configurationfile.
Move instantiation of config into bootstrap.py
Future patches will add even more variables to the cluster config.Adding more parameters wouldn't make the function easier to use andit doesn't make sense to pass them to another function, as it'sonly done once in bootstrap.py on cluster initialization....
Change the results from cli.PollJob
Curently PollJob accepts a generic job, but will return (historyartifact) only the first opcode result. This is wrong, as it doesn'tallow polling of a job with multiple results.
Its only caller (for now) is also changed, so no functional changes...
Enhance the job-related timestamps
This patch adds start, stop, and received timestamp for jobs (and allowsquerying of them), and allows querying of the opcode timestamps.

Abstract the timestamp formatting into cli.py
Currently we format the timestamp inside the gnt-job info function. Wewill need this more times in the future, so move it to cli.py as aseparate, exported function.
Add opcode execution log in job info
This patch adds the job execution log in “gnt-job info” and also allowsits selection in “gnt-job list” (however here it's not very useful asit's not easy to parse). It does this by adding a new field in the queryjob call, named ‘oplog’....
Move a hardcoded constant to constants.py
For now we only use the ‘C’ protocol so we can put it in constants.pyinstead of hardcoding it.
Enable the use of shared secrets
This patch enables the use of the shared secrets for DRBD8 disks, using(hardcoded in constants.py) the md5 digest algorithm.
For making this more flexible, either we implement a cluster parameter(once the new model is in place), or we can make it ./configure-time...
Extend DRBD disks with shared secret attribute
This patch, which is similar to r1679 (Extend DRBD disks with minorsattribute), extends the logical and physical id of the DRBD disks with ashared secret attribute. This is generated at disk creation time and...
Implement job summary in gnt-job list
It is not currently possibly to show a summary of the job in the outputof “gnt-job list”. The closes is listing the whole opcode(s), but thatis too verbose. Also, the default output (id, status) is not veryuseful, unless one looks for (and knows about) an exact job ID....
Nicely sort the job list
Unless we decide to change the job identifiers to integer, we should atleast sort the list returned by _GetJobIDsUnlocked.
Move the pseudo-secret generation to utils.py
The bootstrap code needs a pseudo-secret and this is currently generatedinside the InitGanetiServerSetup function. Since more users will needthis, move it to utils.py
Fix a bug related to static minors
When the node does not yet have any minors allocated, the first minor(0) will not be entered in the ConfigWriter._temporary_drbds structure.This does not happen for our current usage, since we always ask for twominors (so the next call will not match this case), but it will be...
Add checks for tcp/udp port collisions
In case the config file is manually modified, or in case of bugs, thetcp/udp ports could be reused, which will create various problems(instances not able to start, or drbd disks not able to communicate).
This patch extends the ConfigWriter.VerifyConfig() method (which is used...

Switch the global serial_no to the top object
Currently the serial_no that is incremented every time the configurationfile is written is located on the 'cluster' object in the configurationstructure. However, this is wrong as the cluster serial_no should be...
Add serial_no attributes to objects
This patch adds the ‘serial_no’ attribute to the other top-level objects(the configuration object itself, the nodes and the instances).
Replace a cfg.AddInstance with UpdateInstance
This seems to be the last (deprecated) use of AddInstance in order toupdate an instance.
The patch also removes a whitespace-at-eol case.
Fix iallocator name
port forward of patch from revision 1690 with following message:
Patch on revision 1686 used the wrong field: ial.name, which is the instancename and not the iallocator name. self.op.iallocator is the right field.
Sorry for this inconvenience....
Fix a broken format string
This patch fixes a broken format string. It's expecting 3 parameters, but onlygets 2. This change will add the missing parameter. This is a forward-portof the fix in Ganeti 1.2
Switch config.py to logging
A couple of more modules are using the obsolete logger functions, configbeing one of them.
Switch to static minors for DRBD
With some todos remaining, this patch switches the DRBD devices to usethe passed minors, and the cmdlib code (add instance and replace disks)to request and assign minors to the DRBD disks.
Todos: - look at the disk RPC calls to see which can be optimized away, since...
Implement config support for drbd static minors
This patch adds support for allocating static minors.
Like for the LVM uuids, we add a new cache for the temporarily allocatedrequests, and the users of the new methods must manually clear thecache. If this doesn't happen, at worst we lose some minors....
Fix disk replace secondary with static minors

Using the new add/remove infrastructure this becomes pretty easy! :)

jqueue: Add common RPC error handling function
We didn't decide yet what exactly it should do with failed nodes.
Remove locking of instances in certain queries
This patch is similar to the node patch (rev 1650). We disable lockingof instance (and nodes) if we only query static information.
Add an atomic ConfigWrite.GetAllInstanceInfo()
In order to be able to query instance without locking them, we need thesame atomic query of multiple instances as for nodes.
Add ConfigWriter._UnlockedGetInstanceList/Info()
This patch splits the GetInstanceInfo and GetInstanceList methods intotwo parts, one locked one _Unlocked similar to the way nodes arequeried.
Rewrite the 'only submit job' handling in scripts
The "sys.exit(0)" was not nice as you couldn't differentiate it fromother exit codes. We change this to a specially defined exception forthis, so that multi-opcode commands can handle this nicely.
Optimize the OpQueryNodes for names only
Currently, OpQueryNodes is locking all nodes (in shared mode), whichwill also block the special case of querying only for the node names(this is needed for gnt-cluster command, for example). There is nological requirement to not give the administrator enough power if she/he...
Add a way to export all node information at once
The patch adds a new function to export all node information at once(i.e. atomically with respect to the configuration lock).
Never remove job queue lock in node daemon

Parallelize LUQueryInstanceData
Parallelize LUVerify{Cluster,Disks}
These are two easy querying LUs which require shared access to allnodes/instances.
Parallelize LUReplaceDisks
This is the most complex parallelization so far. We have to lock oneinstance (and its nodes) plus one more node if doing a remote replace,or all nodes if doing a remote replace with iallocator.
_LockInstancesNodes: support append mode
This will be used to lock the instance's nodes in addition to some more.
Processor: remove ChainOpCode
This function was incompatible with the new locking system, and itsusage has been removed from the code. For now LUs share code by callingcommon module-private functions in cmdlib.py, in the future they willuse tasklets (when those will be implemented)....
Parallelize LU{A,Dea}ctivateInstanceDisks
Now that they are not used in other opcodes by chaining,this can easily be done.
LUReplaceDisks: remove use of ChainOpCode
The calls to OpActivateInstanceDisks and OpDeactivateInstanceDisks hasbeen replaced by _StartInstanceDisks and _SafeShutdownInstanceDisksrespectively. This is the last usage of ChainOpCode.
Create new _SafeShutdownInstanceDisks function
This new function checks whether an instance is running, before shuttingdown its disks. This is what the Exec() of LUDeactivateInstanceDisksdid, so that is replaced by a call to this function.

This constant replaces what we used to write in recalculate_locks, andrepresents the lock recalculation mode. It lives in constants.py becauseit's used only in cmdlib, and thus doesn't deal with the locking library...
Fix LUReplaceDisks with iallocator
self._RunAllocator() sets self.op.remote_node, but doesn't return thenew remote node. If we set it to the return value of the function webasically reset it to None, and iallocator is never run.

LURebootInstance: lock only primary when possible
When rebooting an instance and we're not changing it's disks status (allthe cases except in a "full" reboot) we can lock just its primary node.
