Please, everyone, checkout what is in
	http://git.linbit.com/gitweb.cgi?p=csync2.git;a=shortlog;h=refs/heads/for-review-may-be-rebased-without-notice

git clone git://git.linbit.com/csync2.git for-review-may-be-rebased-without-notice
respectively
git clone git://git.linbit.com/csync2.git
...
git pull
git checkout -b for-review origin/for-review-may-be-rebased-without-notice
	

Merely compile tested, at this point these are my commits beyond origin/master:

82e842d try to better deal with vanished leading path components
ff17c43 deal with missing leading path components
dc3c471 try to create configured backup directory, if missing
d01d45a add helper functions setup_tag(), detroy_tag()
0c7cd14 add -l (log to syslog) to xinetd example config
0acf57b Whitespace only: piped a few functions through indent
d187023 get rid of compiler warning for (void*)(int) cast
1d685ed add -Wall to CFLAGS
920f202 Fix linking issue 'gnutls_global_init not found', by adding gnutls to LIBS as well
 

Check if the splitting makes sense to you,
if I overlooked or lost something while splitting,
rebasing and doing some cleanups.

Also, if you feel like it, write some decent commit messages ;-)

What realy would be great is some "unit" test cases...

There is one "hidden feature" already,
intended to become the "csync2 tunnel via ssh" mode at some point,
once we figure out how to convince the csync2 *client* to actually use a
pre-established file descriptor for communication.

if you start csync2 in "inetd daemon" mode with stdin connected to a
pipe, it will get the peer information from the "SSH_CLIENT" environment
variable, not from the getpeername() socket api.

So for a unit test on a sigle box, you could do things like
 exec 7> >(SSH_CLIENT="10.11.12.13 7777 8888" ./csync2 -i)
 echo >&7 "CONFIG "
 echo >&7 "HELLO my.fake.hostname.corresponding.to.10.11.12.13 "
 ...

And see what comes back ;-)


Thanks,
