Shorten variable names.
Sanitize the hypervisor names
Since in 2.0 the user will possibly have more interaction with thehypervisor names, we sanitize them by removing the version numbers(the version can be a prerequisite for the ganeti installation, weshouldn't document it in variable names)....
Also export OS_API to the OS scripts
The idea is that if the OSes will support multiple version (e.g. both1.2 and 2.0), then Ganeti should be able to talk to it using version2.0, but then the script needs to be told nicely what version Ganeti isusing....
Fix for gnt-cluster init.
Move the hypervisor attribute to the instances
This (big) patch moves the hypervisor type from the cluster to theinstance level; the cluster attribute remains as the default hypervisor,and will be renamed accordingly in a next patch. The cluster also gains...

Implement job 'waiting' status
Background: when we have multiple jobs in the queue (more than just afew), many of the jobs (up to the number of threads) will be in state'running', although many of them could be actually blocked, waiting forsome locks. This is not good, as one cannot easily see what is...

Implement job auto-archiving
This patch adds a new luxi call that implements auto-archiving of jobsolder than a certain age (or -1 for all completed jobs), and the gnt-jobcommand that makes use of this (with 'all' for -1).
Add a simple timespec parsing function
This function will be used for auto-archiving jobs via the command line.The function is pretty simple, we only support up to weeks since monthsand higher are not 'precise' entities, and dealing with them wouldrequire us to start using calendar functions....
backend.py change to get cluster name from master
Currently there are three function in backend that need the cluster namein order to instantiate an SshRunner. The patch changes these to get thecluster name from the master in the rpc call; once the multi-hypervisor...
Disable re-reading of config file
Since the objects read from the config file are passed to the variousthreads, it's unsafe to re-read the config file (and throw awayConfigWriter._config_data). As such, we disable the re-reading of thefile (since now the master is the owner the file, it makes not sense to...

Start implementation of parallel burnin
This patch introduces a simple framework for executing jobs in parallelin burnin (the ExecJobSet function) and the "--parallel" command lineflag.
The patch also changes the instance creation to run in parallel when the...
Fix gnt-job list with empty timestamps
In case the job object doesn't have a timestamp (which is a separateissue), the listing should not break. We fix this by changing theFormatTimstamp function itself to return '?' in case the timestampdoesn't look good (note that it still can break if non-integers are...
Increase the number of threads to 25
Since our locks are not gathered nicely, we can have jobs that areactually blocking on locks (parallel burnin shows this), so at least weneed to increase the number of threads above the usual number of jobs wecould have in a such a case....
Minor cleanups & typo fixes.
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.
Fix the watcher with down nodes
The watcher didn't handle the down nodes, fix this by ignoring (insecondary node reboot checks) any node that doesn't return a boot id.
Fix the watcher not restarting instance bug
The watcher was using conflicting attributes of the instance: - it queried the admin_/oper_state, which are booleans - but it compared those to the status (which is a text field)
The code was changed to query the aggregated 'status' field, as that...
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...
Fix unittests broken by revision 1727
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...

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’....

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....

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).

Allow listing of the serial_no via gnt-* list

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:

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
The code in 'updating instance configuration' section of the replacedisks with change secondary node was setting a wrong new logical_id forthe drbd devices (only set the new node, not the new minor). The patch...
Extend DRBD disks with minors attribute
This patch converts the DRBD disks to contain also a minor (per eachnode) attribute. This minor is not yet used and is always initializedwith None, so the patch does not have any real-world impact - except forautomatically upgrading config files (it adds the minors as None, None)....
