Renaming ntmake.pl to ntmake.PL (r1742) had unforseen side effects. At least
on freebsd ntmake.PL gets called automatically during build. This is not
desired. I renamed the file to ntmake-build sinc it gets called
explicilty on windows anyway. Reported by Kevin modified by Tobi

Even though POSIX/XSI requires "strerror_r" to return an "int", some systems
(e.g. the GNU libc) return a "char *" _and_ ignore the second argument (user
provided buffer). The configure script now checks for that behavior using
AC_FUNC_STRERROR_R. rrd_strerror() in rrd_thread_safe.c has been updated to
(hopefully) handle all possible cases.

Previously, rrd_strerror() would have returned "strerror_r failed. sorry!" in
mostly any cases when using glibc, since "if (strerror_r())" had been used to
check for errors which evaluates to true if a (non-NULL) pointer was returned.

Now, we, at least, return the error number in case anything else fails.

Thanks to Alessandro Iurlano for reporting this issue after spotting it in
collectd <http://collectd.org>.

Attached a patch for the rrd-tool LIBDBI integration with the following improvements:

a) correct error handling in case of libdbi being unable to load the driver
   was producing segmentation faults.

b) better parsing of datasources

   * until now timestamp fields had to be integer and had to contain a unix
     timestamp - now you can now also use DateTime fields (you still need to
     specify it, as the time-range needs to be defined correctly)

   * data fields are now no longer limited to (var)char or DOUBLE fields -
     FLOAT, INTEGER,... are now also supported.

c) there is a bug with at least LIBDBI 0.8.1 in conjunction with mysql that
   can result in segmentation faults when BINARY/BLOB fields are accessed -
   rrdtool will now tell you about this fact before dying ;)

d) also the value of rrdderivemaxstep only gets applied if derive has been
   selected correctly.

e) "GROUP BY timestamp" has been removed from SQL statement.

f) "ORDER BY timestamp" will be added only in the case of fetching "derived" data.

This patch allows for multiple RRD writer threads to service the queue.

Now, rrdcached can have more simultaneous I/O requests into the kernel.
This may allow the kernel to re-order disk writes, resulting in better
disk throughput. In practice, throughput is increased by 2-3x.

The flush (-f) timer maintenance has been moved from queue_thread_main
into its own thread.

Be more careful about when to use pthread_cond_signal vs _broadcast, since
multiple threads may be waiting on &queue_cond.

As some of you may know that I have created  a patch for rrdtool 1.2 a few years ago, so that a database could be queried  for
values for graphing.

The patch has been mostly rewritten and the following changes have been made:

   * high dependency on mysql has been reduced by avoiding the
     temporary tables (which was bad for mysql replication)
   * The number of executed SQL-Statements for one CDEF has been
     reduced to 1 compared to 11 SQLs (including CREATE TEMPORARY
     TABLE) - for patch against version 1.2
   * All consolidation is done in rrdtool itself (MIN,MAX,AVERAGE)
   * Additional consolidation functions are COUNT and SIGMA, which give
     information on statistics on a per "time-bin" basis.
   * All these consolidation values are always returned as separate
     columns, that are returned by RRD and the consolidation function
     given as Argument is ignored.
     Main reason is that this way there is only one call to rrd_fetcht
     and thus the database even if we need to fetch for example min,
     avg and max. Compare this to 3 calls in case of different
     consolidation functions - and if you want to get SIGMA and COUNT
     as well it is still only one call to the backend and the database.
   * Some previous existing features have been taken out at the moment
     to allow for this reduced set of SQL queries.
         o prediction using the values from the last X days at the same
           time
         o the corresponding sigma calculation
   * The idea is to create generic CDEF's that will do the same thing,
     but that is also available when using RRD-files (similar to TREND,
     but with another scope)
     This will get posted as a separate patch.
   * Overall performance should be much better and the patch as a whole
     simpler.
   * The patch also includes modifications to the configuration
     infrastructure, to make libdbi support optional.

Much simpler handling of timestamp errors.  Return an error to the user
when any of the time stamp values are invalid.  This is similar to
RRDTool's normal behavior.  Removed the complex logic previously used to
return error codes to the user.

This solves a bug where non-advancing timestamps could have produced
incorrect error output during "BATCH" mode.  The bug was cause by using
the sock->wbuf pointer for the error output. -- kevin brintnall

I realize now that the problem is the line

test -f lua/Makefile && cd lua && $(MAKE) install || true

in the target "install-data-local", in bindings/Makefile.am. It forces
execution of bindings/lua/Makefile independently of lua being found or
not. I added that line in my first patch, following perl, python and
ruby build style, but it's not needed after I switched to automake. The
make recursion is controlled by SUBDIRS, which will only contain "lua"

remove_cache_item() did not check whether a file was in queue before
modifying the cache head/tail pointers.  Therefore, the process of
flushing old files may perturb the cache_queue_head pointer.  This caused
some nodes with CI_FLAGS_IN_QUEUE to be un-linked from the queue list.

Thereafter, they would not be flushed by any periodic process (although
they could be revived with FLUSH or UPDATE).  This caused a slow memory
leak for files that are no longer updated.  Pending updates for these
"abandoned" files would remain in memory ad infinitum.

With this patch, remove_from_queue() will check that the item is queued
before modifying the head/tail pointers.  This restores the intended
behavior.
