forked. The JVM internally creates threads that are lost when
forking. This means that Java-based plugins are now configured
during the init-phase, i. e. later than other plugins.
* libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
to Alan Pevec for the patch.

name which prevented this match to be used as documented. Thanks to
Bruno Prémont for finding this problem.
* bind plugin: Fix collection of the cached RR sets. The number of RR
sets currently in the cache was collected as a counter value, which
is nonsense. Thanks to Bruno Prémont for implementing this.

file may be in both locations, especially when the database was
installed in a non-standard path. Thanks to Dusty Doris for
reporting this.
* build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
Solaris, in the configure script automatically.
* build system, tcpconns plugin: Check for `kvm_nlist' and

library with similar functions to the BSD variant, but doesn't
provide these necessary functions.
* collectd.conf(5): Various fixes and clarifications.
* collectd: Remove a GNUism (unnamed unions), thus improving
portability.
* collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.

segmentation fault.
* network plugin: Fix the handling of `type' in the network protocol.
Due to a programming mistake, only 4 or 8 bytes would be copied to a
much larger buffer. This caused the `type' to be transferred much
more often than necessary. In some cases, e. g. the `cpu' and
`cpufreq' plugins being used at the same time, data may be corrupted
in those files. Thanks to Bruno Prémont for debugging and reporting
this issue.
* processes plugin: Fix a possible segmentation fault when specifying
invalid configuration options.
* unixsock plugin: Make sure the initialization function is run only
once. This resolves a file descriptor leak under systems which run

dependencies are not met. Thanks to Bruno Prémont for the patch.
Also, the poisoning of various string functions has been restricted
to debug builds.

*missing* value a couple of bytes would be leaked. Another memory
leak in the configuration handling code has been fixed. Thanks to
Niraj Tolia for reporting these issues.
* collectd: Fix an off-by-one error in the ignorelist functionality.
When using regular expressions, the last character would be missing,
possibly matching differently from what one would expect.

problem.
* collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
Linzberger for reporting the bug.
* iptables plugin: Fix an off-by-one error. If a string was just one
character too long, it was truncated instead of reporting an error.
* network plugin: Fix a memory leak in the configuration handling
code. Thanks to Niraj Tolia for reporting this issue.
* perl plugin: Log an error message if bootstrapping `Collectd' fails.
* postgresql plugin: Don't reopen connection during reinitialization.
This fixes a bug under Solaris and potentially other platforms.
Missing calls to `PQclear' have been added, too. This fixes memory
leaks. Thanks to ``Admin'' for reporting these bugs.
* snmp plugin: Don't expect null-terminated strings from the Net-SNMP
library.
* tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
problems with some `libc's. Thanks to Matthias Lay for reporting the

Also, the poisoning of various string functions has been restricted
to debug builds.
* collectd: Fix a memory leak in the global value cache. With every
*missing* value a couple of bytes would be leaked. Another memory
leak in the configuration handling code has been fixed. Thanks to
Niraj Tolia for reporting these issues.
* collectd: Fix an off-by-one error in the ignorelist functionality.
When using regular expressions, the last character would be missing,
possibly matching differently from what one would expect.
* collectdmon: Don't block SIGCHLD. This fixes a potential portability
problem.
* collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
Linzberger for reporting the bug.
* network plugin: Fix a memory leak in the configuration handling
code. Thanks to Niraj Tolia for reporting this issue.
* perl plugin: Log an error message if bootstrapping `Collectd' fails.
* tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
problems with some `libc's. Thanks to Matthias Lay for reporting the
bug.
2008-09-01, Version 4.4.3
* collectd: Fix a memory leak in the threshold checking code.
* memcached plugin: Fix a too short timeout and a related file
descriptor leak.

function.
* wireless plugin: Work around incorrect noise and power values
returned by some broken drivers.

peer verification.
* ascent plugin: The new ascent plugin reads and parses the statistics
page of an Ascent server.
* cpu plugin: Support for the statgrab library has been added.

* ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
sensor values via IPMI, the intelligent platform management
interface.
* iptables plugin: The iptc library that is used by the iptables
plugin has been added to the distribution, because it is not
provided by all distributions and removed from at least one.
* powerdns plugin: The new powerdns plugin reads statistics from an
authoritative or a recursing PowerDNS name server.

2008-02-18, Version 4.3.0
* collectd: Notifications have been added to the daemon. Notifications
are status messages that may be associated with a data instance.
* collectd: Threshold checking has been added to the daemon. This
means that you can configure threshold values for each data
instance. If this threshold is exceeded a notification will be
created.
* collectd: The new `FQDNLookup' option tells the daemon to use the
full qualified domain name as the hostname, not just the host part
es returned by `gethostname(2)'.
* collectd: Support for more than one `TypesDB' file has been added.
This is useful when one such file is included in a package but one
wants to add custom type definitions.
* collectd: The `Include' config option has been expanded to handle
entire directories and shell wildcards.
* collectdmon: The new `collectdmon' binary detects when collectd
terminates and automatically restarts it again.

* ntpd plugin: The new `ReverseLookups' can be used to disable reverse
domain name lookups in this plugin.
* perl plugin: Many internal changes added support for handling multiple
threads making the plugin reasonably usable inside collectd. The API has
been extended to support notifications and export global variables to
Perl plugins; callbacks now have to be identified by name rather than a
pointer to a subroutine. The plugin is no longer experimental.
* uuid plugin: The new UUID plugin sets the hostname to an unique
identifier for this host. This is meant for setups where each client
may migrate to another physical host, possibly going through one or
more name changes in the process. Thanks to Richard Jones from
Red Hat's Emerging Technology group for this plugin.
* libvirt: The new libvirt plugin uses the `libvirt' library to query
CPU, disk and network statistics about guest systems on the same
physical server. Thanks to Richard Jones from Red Hat's Emerging
Technology group for this plugin.
2008-04-22, Version 4.2.7

overflows, resulting in gaps in the data.
+ Use `memcpy' when constructing/parsing a package to avoid
alignment problems on weird architectures, such as Sparc.
+ Translate doubles to/from the x86 byte representation to ensure
cross-platform compatibility.
