also looks like there's some special initialization necessary for threads. I
doubt that this is handled by the new default behavior in 1.4.4. Don't know
that it's truly necessary if the network plugin is the only plugin using
gcrypt.
Here's a patch that works for me with 1.4.1.
I followed an example for pthread initialization and initialized gcry to 32k,
only since that's apparently the default that's used in 1.4.3. I did it in
network.c's module_register function. Kind of an abuse, I know.

java plugin: Wait with the configuration until the daemon has forked.
Passing the configuration to Java-based plugins requires the JVM to be
active and running. However, the JVM starts some threads that are lost
when the daemon forks to the background.
This patch changes the behavior of the Java plugin to copy the
configuration blocks found to a local variable and run the configuration
of the Java-based plugins from the `init' callback, because it is
invoked after the daemon has forked to the background.

src/utils_cache.c: Update GETVAL output when missing state.
Hi
I think that I've found a bug when use unixsock plugin. The problem is
releate with missing state, when no value is received by daemon for a
while in the cache is marked as MISSING, but the last value is still
showing even when machine is not reporting in a GETVAL and LISTVAL
commands. Some utlities like collectd-nagios does not work correctly,
and report an OKAY value when host is not reporting from a long time.
I attach a patch with check the state value of an cache entry in
uc_get_names and in uc_get_rate_by_name. This patch works for me, but
it's not very tested yet, and I not very sure about if it's a good way
to check the problem. The patch is tested on 4.7.2 release version.
BTW a GETSTATE command will be an useful feature too :P

java plugin: Replace dots ('.') with slashes ('/') when loading a class.
Thanks to Randy Rizun for pointing this out:
Hi!
just wanted to point out an issue in cjni_config_load_plugin
the call to FindClass passes the "Name" verbatim from the LoadPlugin directive
one might intuitively say LoadPlugin "com.foobar.Plugin"
whereas FindClass wants to see it as "com/foobar/Plugin"
so I guess either (a) document LoadPlugin to say to use slashes or (b)
subst / for . in cjni_config_load_plugin or (c) something else?!?
of course, everything works fine if my plugin is in the 'default' java
package (i.e., no package name) =)
either way, thanks a lot for the great work!!

If set to false (the default) then a notification is only generated if a

So, I think that is a bug, if not I'm sorry for the noise :)

src/plugin.c: Initiate the threshold checking again.
Hi,
I have the same problem in my instalation, exactly the same scenario, I found a
possible explanation in the plugin.c module. While in the 4.5 branch exists a
callback to function ut_check_threshold (defined in utils_threshold.c), in the
4.6.2 (and also in 4.6.1, I think), the callback is missing, so threshold
checking never runs.
In fact, a grep -r ut_check_threshold over src dir, only show the definition of
the function in ut_check_threshold module.
I'm not sure if it's really a bug, but when I patched my code, it works fine
for me :) I'm using the 4.6.2 version from tar.gz.

Andrés
