This fixes problems with version 7.21.2 (and later) of libcurl that are due to

df plugin: Improve error message.
notify_desktop plugin: Add compatibility code for libnotify 0.7.
The current code in src/notify_desktop.c is not compatible with the new
libnotify 0.7 API
This:
notification = notify_notification_new (summary, n->message, NULL, NULL);
Should now be:
notification = notify_notification_new (summary, n->message, NULL;
As in, one argument less for notify_notification_new.
But we can't just remove it or it'll break compability with libnotify
0.4.x and 0.5.x.
This piece of code sets dummy NOTIFY_CHECK_VERSION for libnotify-0.4.x,
because NOTIFY_CHECK_VERSION was added only in 0.5.x:
#ifndef NOTIFY_CHECK_VERSION
#define NOTIFY_CHECK_VERSION(x,y,z) 0
#endif
Then we can freely use NOTIFY_CHECK_VERSION, and it will work with all
of 0.4, 0.5 and 0.7 series:
#if NOTIFY_CHECK_VERSION (0, 7, 0)
do something cool
#endif
I'm attaching the working patch. It's been tested with all of the
mentioned versions, as well as it's in active use at Gentoo Linux.
Thanks, Samuli

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.

Since the Debian package doesn't depend on the libraries used by the

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.

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;

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.
Comments and enhancements will be welcome.
