1) Sigma calculation had an error. The first data value in each bin didn't get squared.
2) "rrdfillmissing" was dummy. I have added code to do the work. The parameter has NOW to be in seconds. In doc it is
given in steps. The size of steps depends to much on size of graph so I think its easier to use seconds and internal
calculate the number of steps.

rrdcached: Fix permissions of the default socket.
If neither the "-l" nor the "-P" options have been given, a UNIX domain
socket at a default location is created. However, due to a missing
initialization in this case, the "permissions" field will be left at
zero (no command allowed).

Here is a patch that fixes a serious endless loop problem on 32 bit
architectures near the timestamp 2^31 (oh yes - y2k038 is showing its ugly
face) when using the graph command(s). Once the endtime of a graph is
above the mentioned timestamp, mktime always returns -1 (and correctly
so), causing some loops to loop forever. The patch fixes this, causing
some strange output, but there is no other sane way to handle this (expect
by switching to a 64 bit platform). -- Peter Stamfest

* introduce a new rrd_create_r2 call to fix the no-overwrite api mess
* various fixes to new rrd_cached comands as suggested by kevin
1. Remove opt_no_overwrite and the rrd_create_set_no_overwrite function as they are ugly. Make opt_no_overwrite a local var.
2. Add 'no_overwrite' param to the rrd_create_r and rename as rrd_create_r2, add rrd_create_r that calls rrd_create_r2 with a 0 for the no_overwrite function, preserving the API parameter format but allowing an extended arg list that can be used by rrd_create and rrd_handle_request_create
3. Add -O option to rrdcached command line to force no-overwrite on any creates
4. Add -O option on create via rrdcached to optionally add no-overwrite (cannot remove it is it was previously set at start)
5. Fix rrd_handle_request_last to check the queue instead of forcing a flush. Remove -no-flush option from LAST command since it is now no longer relevant as we're querying the cache chain
6. Fix ulong/unsigned long issue for compilation under windows
7. Change rrd_handle_request_create to only accept timestamp parameters, not at-syntax, in order to be threadsafe. This is no loss since the rrd_client already pre-parses any at-style syntax
8. Reinstate missing free() in rrd_info.c and rrd_last.c

First bug: in function rrd_fetch_fn_libdbi() variable 'struct sql_table_helper table_help'
field 'filename' is uninitialized. So, if a sql error happens, it does not print an error like this
rrd_set_error( "libdbi: problems connecting to db with connect string %s - error: %s",th->filename,dbi_errstr);
instead of, it dumps core.
Second bug: when the output data buffer is allocated, it allocated for 'rows-1' max index, but in
'fetch loop' 'idx' may be equal to 'rows', so it needs one more extra record in data.

src/rrd_client.c: Fix a potential segmentation fault in "get_path".
The "get_path" function is called at least from "rrdc_update" without
checking for a connection first. In that case the "sd_path" pointer may be
NULL, so dereferencing it without checking for NULL is not good behavior.
This patch checks all arguments of the "get_path" function and returns an
error if any pointer is NULL. -- Florian Forster

Rather than calling "FLUSH" for each RRD file needed for drawing a
graph and then accessing the file directly, use the "FLUSH" command to
receive the data required for drawing a graph.
The daemon can now be specified in one of three ways:
* A new option has been added to the "DEF" option. If the "DEF" command
includes the option "daemon=...", then the given daemon is used for
accessing that file only. This option takes precedence over all
other options. The value given follows the same syntax as other ways
to specify a daemon address, thouh colons need to be escaped from
rrdgraph(1).
Example:
'DEF:v1=path/to/example.rrd:value:AVERAGE:daemon=collect1.octo.cx'
* The "--daemon" option can be given to the overall "rrdtool graph"
command. When given, this address is used for all file accesses
except those which explicitely contain a "daemon=..." option.
* If the "RRDCACHED_ADDRESS" environment variable is set, it's value
is used as the daemon address. This is the lowest priority option
and only used if no other option is given.
One nice detail is that with ":daemon=...", the cache address can be
specified for each "DEF:" definition. It is therefore possible to graph
values stored on several servers in one graph ? even if several RRD
files have the same name. -- Florian

src/rrd_format.c: Implemented "cf_to_string"
A simple helper function to turn an "enum cf_en" to a string. The returned
pointer points to static memory and doesn't need to be freed. -- Florian

src/rrd_fetch.c: Use "rrdc_fetch" if daemon is available.
Instead of flushing the file via the connection to the daemon and then
accessing it directly, use the "FETCH" command to access the file via
the RRDCacheD. This removes ambiguities with absolute and relative paths
and makes it possible to read data from files that are not available
locally. -- Florian

Add a "FETCH" command to RRDCacheD which behaves like a (simplified
version of) rrdfetch(1).
This has advantages over calling "FLUSH" from within the "client",
especially if the daemon is accessed using a network socket. For one, it
makes it easy to separate collecting and storing of data on one side and
creating graphs on another, possibly more public server. Without this
command this is only possible using networked file systems and similar
techniques.
When talking to an instance of RRDCacheD via a network socket, only
relative pathnames are allowed. If the RRD file is to be accessed
afterwards (why else would one call "FLUSH"?), the client has to be in a
specific directory so the *same* relative path can be used. If the file
is on a share mounted via the network, the required CWD may differ from
the CWD of the server, making developing and deploying solutions using
separated storing and graphing unnecessarily hard.
The data can be accessed using "rrdc_fetch" which should be a drop-in
replacement for "rrd_fetch_r". This makes it easy for programs using the
RRDtool C API to use this new functionality. -- Florian Forster

* GRAD element for graph, it acts more or less like an AREA,
except you can specify a second color and a height which is used to
create a gradient from one color to the next
