Fix compilation error with plugin_register_shutdown
Compiling collectd-4.10.2 on an OpenSuSE 11.3 system causes the
following error:
snmp.c: In function ‘module_register’:
snmp.c:1620:3: error: passing argument 1 of ‘plugin_register_shutdown’ discards qualifiers from pointer target type
plugin.h:275:5: note: expected ‘char *’ but argument is of type ‘const char *’
Convert plugin_register_shutdown's name argument from 'char *' to
'const char *' in order to match the other plugin_register_*
functions.

dispatch proper values in Python write plugin
Fixes the Python write callback so the appropriate value is dispatched to
Python. Previously, the code only looked at the first element of a data set
to determine which value type (GAUGE, COUNTER, etc) to dispatch. If your data
set consisted of multiple values of different types, then the Python write
plugin was receiving bad values for the elements at position n > 0 whose type
was not the same as that at position 0.

src/plugin.c: Print a more verbose error message if lt_dlopen() fails.
Since the Debian package doesn't depend on the libraries used by the
collectd plugins, some plugins may fail to load. ltdl reports this with
the very confusing error message "file not found". Since the plugin is
in fact available, many users don't realize a dependency is missing and
assume collectd is looking in the wrong directory -- and they are hardly
to blame for this.
This commit introduces a lengthy error message which hopefully points

Joey Hess has reported a problem when creating notifications from

"free" is currently 1773072384.000000. That is above the warning
threshold of nan%.
A new section will handle this case correctly. In the inverted case, the

Fix errno thread-safety under AIX
Unlike Linux or Solaris, errno under AIX is not thread-safe by
default.
This patch sets _THREAD_SAFE_ERRNO when AIX is detected in order to
force the thread-safe implementation of errno. Without this, calls
like stat() in the rrdtool plugin fail with errno incorrectly set,
leading to the inability to create previously absent rrd files.
Maybe _THREAD_SAFE should be set instead, to prevent other possible
threads-related problems, but this is enough to scratch my current
itch...
Here is the relevant part of /usr/include/errno.h on AIX:
#if defined(_THREAD_SAFE) || defined(_THREAD_SAFE_ERRNO)
/*
* Per thread errno is provided by the threads provider. Both the extern
* int
* and the per thread value must be maintained by the threads library.
*/
extern int *_Errno( void );
#define errno (*_Errno())
#else
extern int errno;
#endif /* _THREAD_SAFE || _THREAD_SAFE_ERRNO */

collection3: fix multiple hosts selection issue
When selecting multiple hosts in collection3's hosts list, and with some

This patch addresses this issue by modifying the name of the hash key
in the group_files_by_plugin_instance function, making it less prone
to name collisions by prefixing it by the host name.

snmp.c: compilation fixes for AIX
The C and C++ standards allows the character type char to be signed or
unsigned, depending on the platform and compiler. Most systems,
including x86 GNU/Linux and Microsoft Windows, use signed char, but
those based on PowerPC and ARM processors typically use unsigned char.
This patch fixes a "comparison is always true" warning on AIX (powerpc)
which leads the compilation to abort because of the -Werror flag.
Being unsigned by default, a char is always >0.

Bugfix for libcollectdclient lcc_putval.
Hello,
I'm using collectd to monitor system and process parameters of our code under
test running on a cluster. The test processes communicate to collectd via the
unixsock plugin, but there was a small error in the client library which I had
to fix first.
The wire format of the putval command is missing a space behind the closing
double quote of the identifier. As I said, it is a small fix, but nevertheless
I attached the patch for client.c. The bug is present in 4.6 (that is the
version I'm using in production), but I fixed it against 4.10.0.
Cheers,
Johan
