expanded to the literal escaped character.

tables plugin: Added a generic plugin to parse tabular data.
Currently, the main purpose of this plugin is to be able to get information
from the Linux proc filesystem but it should be flexible enough to get data
from other sources as well.
Values are selected based on a given column separator and column numbers. The
configuration is a kind of a mix of the tail and *sql plugins' configurations.
A sample configuration might look like this:
<Plugin table>
<Table "/proc/slabinfo">
Instance "slabinfo"

InstancePrefix "active_objs"
InstancesFrom 0
ValuesFrom 1
</Result>

InstancePrefix "objperslab"

fc_register() may now be used to register matches and targets with collectd.
The function takes three arguments: type, name, proc. 'type' has to be any of
FC_MATCH or FC_TARGET, 'name' specifies the name of the target / match and
'proc' is a hash of callbacks (specified by name just like any other
callbacks). There are three types of callbacks: create, destroy and match /
invoke - the former two being optional.
The match / invoke callback has to return any of the following statuses:
FC_MATCH_NO_MATCH, FC_MATCH_MATCHES, FC_TARGET_CONTINUE, FC_TARGET_STOP or
FC_TARGET_RETURN. If none of those constants are used, the behavior is

`legacy_mode' and `legacy_position'. The `legacy_mode' member is used
to switch to a new set of functions for handling these special
results.
- Those ``legacy results'' use only a small subset of the members in

functions:
udb_legacy_result_finish_result
udb_legacy_result_handle_result
udb_legacy_result_prepare_result

automatically call the legacy version if the `legacy_mode' member is
set to `1'.

Fixed various signedness issues identified by -Wextra.
The following two issues have been addressed:

throughout the code and has been fixed by switching to more appropriate
types or adding appropriate explicit casts.
* comparison of unsigned expression < 0 is always false - this was found in
the processes and vserver plugins where a size_t had wrongly been used
instead of a ssize_t and an int respectively.

Document unused parameters.
In all cases where unused parameters have to exist either because some API
requires it or for more consistency, they now have been documented using

used to prevent problems with compilers not supporting attributes). In a few
other cases, the parameters have been removed.

well, when using -Wall).

contrib/php-collection: Save/load graph list and fix HTTPS handling.
Hi,
An update to the graphing interface. (incremental patch attached)
This fixes security complaint by a few browsers when page is accessed
via HTTPS and also makes sure the graphs and lists will load if HTTP
and HTTPS paths differ.
Thanks to Mullet- for spotting this issue.
In addition to the fix above this patch adds support for saving
current graph list to a cookie and appending graph list read from
cookie to the currently displayed list.
A future extension would be to allow saving/loading named graph lists
so multiple list can coexist (pretty useful when monitoring multiple
servers/services)

contrib/php-collection: Add a PHP frontend for graph generation.
Hi,
Attached is a patch with a set of PHP files for a complete graphing
environment for collectd-generated RRDs.
Before generating a graph with rrdtool it can tell collectd to flush
the RRDs that are about to be used.
The interface is built with dynamic HTML.
It provides following options:
- host selection
-> plugin selection
--> plugin instance selection
---> type selection
----> type instance selection (or meta graph)
- linear / logarithmic Y-scale
- verbose / minimal legend
- [Add Graph] [Remove all Graphs] [Refresh Graphs]
For each displayed graph:
- Move above previous graph
- Refresh graph
- Remove graph
- Move below following graph
I tested on following browsers:
- Firefox-3.0
- Safari-3.2 (Win32)
- Konqueror (KDE-4.1.3)
- Webkit (webkit-gtk-0_p40220)
- Internet Explorer (6, 7, 8rc - CSS layout issues with <8)
Dependencies:
- PHP-5 (might run with PHP-4)
> GD suport for error images
> Ability to execute rrdtool binary
> Unix socket for FLUSH support
- RRDTool (rrdtool graph, rrdtool info)
TODO: complete/improve graph definitions in definitions.php

Let plugin_dispatch_values() set value_list.time in case of 'now'.
Basically any (read) plugin was calling time(NULL) to set the time of a values
list. This is now done by plugin_dispatch_values() in case the time is zero
(which is the case when using VALUE_LIST_INIT or VALUE_LIST_STATIC).
This change slightly simplifies the code and makes future changes to the time
management (like the possibly upcoming subsecond resolution support) less
intrusive in respect to the amount of required code changes.

Converted timeval_sub_timespec() to timeval_cmp().
The third (return) argument is now of type 'struct timeval' (instead of
'struct timespec') as well. Also, it may now be NULL, in which case the
difference is not returned. This is a more general and thus more flexible
approach that permitted to remove the custom timeval_sub*() implementations in
the multimeter and ntpd plugins.
The return value has been changed to reflect the return value used by
functions like strcmp(), i.e. it is less than, equal to, or greater than zero
if the first argument is less than, equal to, or greater than the second
argument respectively.
In the cases where a 'struct timespec' is required, the return value is now
converted by multiplying the tv_usec member with 1000.

ipmi plugin: sensor_read_handler: Removing sensor Temp 1 system_internal_expansion_board (16.1), because it failed with status 0x10000d5.
This patch attempts to provide slightly better error message and just
skip current reading iteration if the error
IPMI_NOT_SUPPORTED_IN_PRESENT_STATE_CC is indicated.
This error happens e.g. when iLo firmware is upgraded (or reboots?) on
HP servers.
On a server IPMI readings suddenly failed causing the plugin to stop
collecting data.

src/plugin.c: Add the `{Pre,Post}CacheChain' options and appropriate chains.
The PreCacheChain is executed before the values are added to the cache, the
PostCacheChain afterwards. If no post-cache chain is given, values will be
dispatched to all write plugins by default.
