This moves selection of the initial RRA row into the rrd_open.c API
The current implementation (random row) is used by default. However, it
now provides an opportunity for alternative implementations to integrate
with rrdtool in a single place.
Maybe there are other places in rrdtool where I should insert calls to
the function rrd_notify_row()?
This has been tested with rrdtool create and rrdtool info to verify that
random rows are selected by default (existing behaviour preserved).

Under most circumstances, rrdcached can detect a stale pid file.
If the process in the pid file does not exist, or cannot be signalled by
the rrdcached owner, then rrdcached will replace the pid file and start
normally. Otherwise, it will complain verbosely to STDERR.

/base/dir/x.rrd

Now, the daemon will check that a base directory is NOT reached via
symbolic link. Documentation added to illustrate the restriction.
This allows several simplifying (and performance-enhancing) assumptions to
be made elsewhere in the code:
* it ensures that paths resolved in the client via realpath() will match
our data structure keys
* it's possible to generate the correct absolute path when given a
relative path by simply prepending the base directory
* it's not necessary to resolve paths that begin with '/'

Some observations I made while implementing this:
- In rrd_open(), the call to rrd_init() clobbers values already populated in
rrd_create.c
- The logic for newfile_size in rrd_open() wasn't really able to cope with the
logic for a file starting with size 0

doing high volume processing. This enables about 25% speed increase
during journal replay and "BATCH" processing. (this is a function of
syscall overhead).

timestamp for all commands

* After reading journals at startup, only trigger full flush out to disk
if the user specified -F. Avoids unnecessary IO on startup unless the
user also wants unnecessary IO on shutdown.
* journal_replay is much more careful about files it will open
* must be a regular file
* must be owned by daemon user
* must not be group/other writable
* Ensure that the journal gets created with the right permissions.
... even when the daemon is invoked with a permissive umask.

interpret as many commands as arrive in a single read(), and it will use
fewer write()s when there are multiple output lines.
All routines now pass around listen_socket_t objects instead of file
descriptors.
All I/O is now contained in two routines. It's no longer necessary to
specify the line count in multi-line outputs, since that is calculated
automatically.

Fixes for the following compiler warnings:
- unused variable
- unused parameter
- assignment / argument discards qualifiers from pointer target type
- comparison between signed and unsigned
- too many arguments to function
- assignment makes pointer from integer without a cast
- incompatible pointer type
- differ in signedness
- implicit declaration of function
- enumeration value not handled in switch
- value computed is not used
Most notably, a possible segfault in the Rrd_Lastupdate() code of the TCL
bindings has been fixed.
Also, -Wundef (warn if an undefined identifier is evaluated in an #if
directive) has been removed from CFLAGS. I don't see any problem with letting
undefined identifiers evaluate to "false" in rrdtool. Keeping that option
would produce a lot of (imho unnecessary) errors which would need to be fixed
using ugly preprocessor statements like '#if defined(FOO) && FOO'.

I've adapted an init script for rrdcached, and also incorporated it into
the spec file so that it is deployed with the RPM.
There are also some other changes to the spec file so that I could build
an RPM successfully from trunk. I'm happy to tidy up the spec file some
more if no one else wants to mandate the best way to do it.
By default, rrdcached runs as nobody. I've tested this on a server
running Ganglia gmetad.

Daniel

Now, moving a value to the head of the queue is O(1). Before it was
O(queue size). This improves performance of individual flushes when
there is a large number of files in the queue. As a result, we don't
hold the cache_lock as much.
Revamped enqueue_cache_item to take advantage of the new structure.
Renamed _wipe_ci_values to look nicer with other code.

This patch introduces the concept of socket privilege levels. "UPDATE"
and "FLUSHALL" commands are restricted to high-privilege sockets. "FLUSH"
commands can be executed on any socket. This is ideal for multi-user
installations where only certain users need write access to the RRD files.
Now, nearly all socket information is passed around the daemon in
listen_socket_t data structures. In case there is other per-socket state
(i.e. if we add authentication) we can put it there.
Also, I created a new "open_listen_socket_network" and removed the network
setup from "open_listen_socket". -- kevin

The PID file is created with open() in the parent process, while we still
have STDERR open. If it cannot be created, it complains verbosely to
stderr.
The PID file is written in the child process. The only way the fdopen()
will fail on a fd that is already open is if you're completely out of
memory. As in other places in the code, I didn't consider this a case
that required a very verbose message. (Search for "strdup failed"). If
you still think a more verbose message is called for, please suggest one.
The attached patch corrects the error message to complain about fdopen()
vs fopen(). I hadn't noticed that until you brought it up.

Support for IPv6 has been broken with revision 1522: Because IPv6-addresses
contain colons, simply checking for a colon and using everything after it does
destroy correctly formatted IPv6-addresses.
This patch checks for dots '.' in the address. If the address contains at least
one dot, it is considered to be a hostname or an IPv4-address and a simple
search for a colon is done.
If no dot is found, the code will check for an opening square bracket '[' at
the beginning of the address. If one if found, the format
[address]:port
is assumed.
If neither applies, the default port will be used.

Fix for debian bug 498183 ... never *advise after the end of the
file. On sparc this causes a segfault. Thanks to Sebastian Harl and Jurij Smakov for finding this.

The previous code was broken: The response was read using `read(2)'. If
the server wasn't sending fast enough, the client would stop reading
before the entire message had been read.
This patch changes the communication code to use the (line based)
`fgets' function rather than the lower level `read' function. After
reading the first line (which contains the total number of line to be
expected), this precise number of lines is read - blocking if necessary.
Also, the missing four new statistic values have been added to
`rrdc_stats_get'.

RRDcached patch. This implements an infrastructure, where rrd updates can be
sent to a daemon which caches them prior to bulk-updateing rrd files. See the rrdcached manual page.

regarding #183:
* move part of rrd_config.h out to a separate file, so that
autoconf is not confused by the more complex expressions.
* fix configure variable name to allow caching
* another attemt at fixing solaris 2.8 compile so that it
works out of the box.

The attached patch eliminates the many places where the rra_current pointer was maintained; the existing write/seek mechanisms update rrd_file->pos correctly.
Also, the seek at the front of process_arg is not necessary; write_to_rras will now take care to correct the file position at every update cycle.
This eliminates unnecessary rrd_seek() calls when MMAP is not enabled. -- kevin brintnall kbrint rufus.net
