Fix queue archive creation with wrong permissions
On a master failover some of the archive dirs might have wrongpermissions in the non-root model. This is due to the nature of nodedstill running as root and the job queue is synced that way. This patchwill fix this behaviour by setting the permissions accordingly....
utils: Fix UnescapeAndSplit parsing bug

Reopen daemon's stdio on SIGHUP
Before this patch daemons would continue to refer to an old logfile fortheir standard I/O if they had been asked to reopen the log (SIGHUP).

Reopen log file only once after SIGHUP
Commit b6fa9a44 added a re-openable log handler. The log file isreopened when a daemon is sent a HUP signal. Due to a bug in the code,fixed by this patch, the log file would be reopened for every single logmessage thereafter....
Don't leak file descriptors when setting up daemon output
When a daemon's output is configured using “utils.SetupDaemonFDs”, thefunction must use dup2(2). Unfortunately the code didn't close theoriginal file descriptors, leaking them in the process.

mlock: fail gracefully if libc.so.6 cannot be loaded

Fix WriteFile with unicode data
Unicode is fun, indeed:
len(buffer("abc"))
3
len(buffer(u"abc"))
12
So we can't pass unicode data to buffer(), as the result will be towrite the in-memory (usually UTF-32) representation to disk.

Fix potential data-loss in utils.WriteFile
os.write can do incomplete writes, as long as at least some bytes havebeen written (like write(2)):

utils.WriteFile: Close file before renaming
Issue 154 (http://code.google.com/p/ganeti/issues/detail?id=154)reported an “Operation not supported” error when writing instanceexports to a mounted CIFS filesystem. Experimentation showed the errorto only occur when using rename(2) on an opened file. Various references...

utils.log: Restrict I/O error handling coverage
The I/O error will occur while opening the file, not while addingand configuring the handler.
utils.log: Split formatter building into separate function
Introduce re-openable log record handler
This patch adds a new log handler class based on the standard library'sBaseRotatingHandler. This new class allows the log file to be re-opened,e.g. upon receiving a SIGHUP signal. The latter will be implemented in...
cluster verify: add hvparams verification
Currently, the validity of the hypervisor parameters is only checkedat init/modification time, and not in the cluster verify. This is bad,as it can lead to inconsistent state that is only detected when thenext modification (which can be unrelated) is made, leading to...
