- run-in-tempdir should depend on what it copies to the temporary dir
- Add PYTHON_BOOTSTRAP to BUILT_SOURCES
- Don't use “mkdir -p” directly
- Create directory if necessary for writing bootstrap script

In summary, this should make “make distcheck” in pristine
checkout work again.

Eventually this will help ensuring that clients and servers are of the

it's relatively easy for gnt-* and ganeti-* to be from a different
version.

Scripts will be at ganeti.client.gnt_* and a small bootstrap script
calls a “Main” function from the module.

There have been many bugs in gnt-node modify. Let's try to introduce
some more.

This patch reworks the node role changes from tracking the flag changes
to completely overwriting the flags based on the new role. This paves
the way for (in 2.4 or later) moving to a single attribute for nodes.

We compute the old role and the new role based on the required changes
and whether we need to auto-promote. Once this is done, the body of the
Exec() function becomes trivial (there's more code related to output
formatting than the node flag changes).

Another advantage of the new version is that the entire flags are
overwritten, and that all are changed at the same time, making it
impossible (harder?) to have partial updates.

By default all names are checked (LUCreateInstance, name_check). In some
cases it can be useful to disable this check, but doing so was not
allowed for remote imports. One should be aware, however, that using
this feature can lead to rename script failures when importing a remote
instance without the proper name, e.g.:

“Failed to run rename script for inst1 on node node3.example.com: OS
rename script failed (exited with exit code 1), last lines in the log
file:\nCannot rename from inst2.example.com to inst1:\nInstance has a

In the context of a node, its group has (at least today) only one
meaning, that is the node's node group. As such, we rename
node.nodegroup to just node.group.

Note: if we want to keep node in there, it should be at least
node_group, for consistency with the other node attributes.

Similarly, we rename the OpAddNode nodegroup attribute to group.

If the configuration file doesn't denote this node as master, we prevent

This fixes a recently diagnosed race condition between master failover
and the watcher.

Currently, the master failover first stops the master daemon, checks
that the IP is no longer reachable, and then distributes the updated
configuration. Between the stop and the distribution, it can happen that
the watcher starts the master daemon on the old node again, since ssconf
still points the master to it (and all nodes vote so).

In even more weird cases, the master daemon starts and before it manages
to open the configuration file, it is updated, which means the master
will respond to QueryClusterInfo with another node as the real master.

This patch reorders the actions during master failover:

- first, we redistribute a fixed config; this means the old master will
  refuse to update its own config file and ssconf, and that most jobs
  that change state will fail to finish
- we then immediately kill it; after this step, the watcher will be
  unable to start it, since the master will refuse startup
- and only then we check for IP reachability, etc.

I've tested the new version against concurrent launch of the watcher;
while my tests are not very exhaustive, two things can happen: watcher
see the daemons as dead, and tries to restart them, which also fail; or
it simply get an error while reading from the master daemon. Both these
should be OK.

This should fix the case where there are two masters that both try to

will "win" the ownership of the config.data.
