Thanks to Dusty Doris for + reporting this. + * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by + Solaris, in the configure script automatically. + * collectd.conf(5): Various fixes and clarifications. + * apcups plugin: Include "collectd.h" before . This solves + portability problems, especially for Solaris. + * dns plugin: Fix a portability problem with NetBSD. + * 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. + * unixsock plugin: Make sure the initialization function is run only + once. This resolves a file descriptor leak under systems which run + the initialization more than once, such as Solaris. + +2008-10-16, Version 4.4.4 + * build system: Change `--enable-' to abort with an error if + dependencies are not met. Thanks to Bruno Prémont for the patch. + 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. + * memory plugin: A typo in the libstatgrab code has been fixed. + * snmp plugin: Fix a possible memory leak. + +2008-07-15, Version 4.4.2 + * build system: Use pkg-config to detect the upsclient library. + * collectd: Try even harder to determine the endianess of the + architecture collectd is being built on. + * disk plugin: Fix for Linux 2.4: A wrong field was used as the name + of disks. + * dns plugin: Fix compilation errors with BIND versions 19991001 + through 19991005. + * network plugin: Bugfix in the init routine: The init function + cleared a buffer regardless of its contents. This could lead to lost + values under Solaris. + * nginx plugin: Remove usage of the thread-unsafe `strtok' function. + * vserver plugin: Remove usage of the thread-unsafe `readdir' + function. + * wireless plugin: Work around incorrect noise and power values + returned by some broken drivers. + +2008-06-03, Version 4.4.1 + * collectd: Fix the `DataSource' option within `Type' blocks. Thanks + to kyrone for reporting this. + * collectd: Fixed min/max output in notifications generated by + threshold checking. + * collectd-nagios: Fix the protocol used to communicate with the + daemon. + * perl plugin: Fail noisily, but don't shutdown the daemon, if + initialization has errors. An issue with Perl 5.10 has been fixed. + * teamspeak2 plugin: Fixed an out of bound array access. Thanks to + René Rebe and Siegmund Gorr for reporting this. + +2008-05-06, Version 4.4.0 + * collectd: Internal code cleanups. + * collectd: Added support for a `Flush' command in the unixsock and + exec plugins. This command can be used to force a plugin (or all) to + flush its values to disk. + * collectd: Thresholds can now be configured to apply to one data + source only, making it possible to configure different thresholds + for each data source. + * apache, nginx plugins: Added the possibility to disable host and/or + 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. + * disk plugin: The possibility to ignore certain disks or collect only + specific disks has been added. + * disk 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. + * rrdtool plugin: The size of the files generated with the default + configuration has been decreased. + * tail plugin: The new tail plugin can be used to gather statistics by + continuously reading from log files. + * teamspeak2 plugin: The new teamspeak2 plugin connects to a + TeamSpeak2 server and collects statistics about the number of users + and number of channels. + * users plugin: Support for the statgrab library has been added. + * vmem plugin: The new vmem plugin collects very detailed statistics + about the virtual memory subsystem of Linux. + +2008-08-30, Version 4.3.4 + * Build system: Improved detection of and linking with the statgrab + library. + * collectd: Portability fixes, especially to determine endianess more + reliable. + * Various plugins: Fix format strings. + * disk plugin: A fix for giving disks under Linux 2.4 the right names + again has been applied. + * memcached plugin: Fix a too short timeout and a related file + descriptor leak. + * memory plugin: A typo in the libstatgrab code has been fixed. + * network plugin: A fix in the initialization function solves problems + under Solaris. + * nginx plugin: A thread-unsafe function has been replaced. + * vserver plugin: A thread-unsafe function has been replaced. + * wireless plugin: A work-around for broken wireless drivers has been + added. + +2008-04-22, Version 4.3.3 + * build system: Improved detection of several libraries, especially if + they are in non-standard paths. + * build system: Portability fixes: Automatically define "_REENTRANT" + if the libc expects it. + * collectd: Error and warning messages have been improved. + * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before + using them. + * apache plugin: Allocate new memory when reading a webpage instead of + using a buffer of static size. + * exec plugin: Close (almost) all filedescriptors before exec(2)ing + the program. + * hddtemp plugin: Error and warning messages have been improved. + * sensors plugin: Fix sensor collection for some chip types. + +2008-03-29, Version 4.3.2 + * collectd: Fix configuration of the `FailureMax', `WarningMax', and + `Persist' threshold options. + * collectd: Fix handling of missing values in the global value cache. + * collectd: Improved error messages when parsing the configuration. + * sensors plugin: Fix temperature collection with libsensors4. + * unixsock plugin: Fix mixed input and output operation on streams. + * wireless plugin: Fix reading noise value. + +2008-03-05, Version 4.3.1 + * exec plugin: Set supplementary group IDs. + * network plugin: + + 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. + * ping plugin: Correct the handling of the `TTL' setting. + * swap plugin: Reapply a patch for Solaris. + * tcpconns plugin: Portability improvements. + +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. + * csv plugin: The CSV plugin is now able to store counter values as a + rate, using the `StoreRates' configuration option. + * exec plugin: Handling of notifications has been added and the + ability to pass arguments to the executed programs has been added. + * hddtemp plugin: The new `TranslateDevicename' option lets you + disable the translation from device names to major-minor-numbers. + * logfile plugin: Handling of notifications has been added. + * 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 + * build system: Improved detection of several libraries, especially if + they are in non-standard paths. + * build system: Portability fixes: Automatically define "_REENTRANT" + if the libc expects it. + * collectd: Error and warning messages have been improved. + * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before + using them. + * apache plugin: Allocate new memory when reading a webpage instead of + using a buffer of static size. + * exec plugin: Close (almost) all filedescriptors before exec(2)ing + the program. + * hddtemp plugin: Error and warning messages have been improved. + * sensors plugin: Fix sensor collection for some chip types. + +2008-03-29, Version 4.2.6 + * collectd: Improved error messages when parsing the configuration. + * sensors plugin: Fix temperature collection with libsensors4. + * unixsock plugin: Fix mixed input and output operation on streams. + * wireless plugin: Fix reading noise value. + +2008-03-04, Version 4.2.5 + * apache plugin: Improved initialization and error messages. + * exec plugin: Set supplementary group IDs. + * network plugin: + + Create separate threads for reading from the socket and parsing + and dispatching incoming packets.
