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).

This patch fixes this problem by allowing all commands on the default

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

1. Add INFO  <filename>, FIRST <filename> <index>, LAST <filename> and
   CREATE <rrdfile> [-b start][-s step][-O] <DSdefs> <RRAdefs> to the rrdcached
   functions.

2. Add rrd_create_set_no_overwrite as a function in rrd_create.c to allow
   the overwrite flag to be set from rrd_daemon.c

3. Add rrdc_info, rrdc_first, rrdc_last, rrdc_create functions in
   rrd_client.c

4. Add rrdcached support to rrd_info(), rrd_first(), rrd_last() and
   rrd_create()

5. Add --noflush (-F) option to rrd_info(), rrd_last() to prevent cache
   flushing before function call if required for efficiency

6. Add --daemon option to rrd_info(), rrd_first() for rrdcached support

7. Add buffer_add_ulong function to rrd_client.c (used by new rrdc_*
   functions)

8. Add rrd_clear_error() call to rrd_create_r () to clean up bug if create
   called more than once

9. Add -O option to rrdcached to force no-overwrite mode in CREATE function

10. All relevant documentation updated

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

Instead of flushing the file via the connection to the daemon and then

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
