* detect short/truncated files on open (rrdtool used to crash later
on some platforms)
* stop rrd_resize from altering the original file (mmap side
effect)
* fix VDEF and SHIFT use. Now it returns correct data and does
not crash anymore.
* fix rrd_xport when used on datasources with different
resolutions. This has been broken from day 1 of this tools
exsitance.
* fixed default prefix for ruby install
* added rpath for perl bindings on bsd
* do not [fm]advise past the end of the file since this
causes crashes on sparc.
Local change warranting nb1 is to prefix some error messages from
rrdupdate with the name of the file the error relates to, carried
over from nb1 of 1.2.27.
Update loosely OKed by martti@
The announcement of 1.3.0 outlines the changes since 1.2.27:
NEW Fast file access methods (Bernhard Fischer / Tobi Oetiker)
----------------------------
* introduced file-accessor functions rrd_read/rrd_seek/rrd_write
* implemented full mmap-based file access with madvise hints for
improved scalability, much reduced memory-footprint and much less
blocking while accessing the disk
* implemented optional full file-descriptor access instead of FILE*
access
NEW Graphing (Tobi Oetiker)
------------
* libart has been replaced by cairo/pango
* pango markup is supported (--pango-markup)
* full grid fitting
* --graph-render-mode=mono for non anti aliased graphing
* --font-render-mode=mono for non anti aliased fonts
* fonts come through fontconfig, use the Pango font nameing scheme
-> 'Times 20' ... it is not possible to use truetype fonts
directly anymore.
* Tabs are position independent.
* TRENDNAN filter that ignores NAN values while calculating the
TREND data. (Timo Stripf)
* --full-size-mode to specify the outer border of the image and not
just of the graphing canvas (Matthew Chambers)
* TEXTALIGN command to alter default text alignment behavior
* C API in-memory graphing with rrd_graph_v (Evan Miller)
* draw dashed lines in graphs (Thomas Gutzler)
* new interface graphv which returns information using the rrd_info
interface (Tobi Oetiker and Mark Plaksin)
* improved horizontal grid. Have a bit more grid lines and y-axis
labels while keeping them far enough apart to not run into each
other.
NEW Forecasting (Evan Miller)
---------------
* the new MHWPREDICT consolidation function uses a variation of the
Holt-Winters method. It is a drop-in replacement for HWPREDICT,
and is better suited for data whose seasonal variations grow or
shrink in proportion to the average.
* If you create an RRD with the new MHWPREDICT function, the
resulting rrd file will be version 0004 and can only be used in
rrdtool 1.3.
Rewrites
--------
* rrd_restore now uses libxml for parsing which makes things much
more tolerant towards xml variations. The old code could mostly
just parse the XML as it was output by rrdtool dump. See also:
the note at the bottom of this document. (by Florian octo
Forster)
* rrd_update rewritten to make it more modular. Fixed two
longstanding HW bugs in the process (Evan Miller)
Internationalization (Takao Fujiwara and Tobi Oetiker)
--------------------
* The help output by rrdtool has been internationalized. There are
no real translations included with rrdtool yet, contributions are
welcome.
* The internationalization will only be compiled if libintl and
friends are available on your system. Use the configure option
--disable-libintl if you want to disable this feature
Language Bindings
-----------------
* ruby rrd_fetch will return step as a last property -- Mike Perham
RRDtool dump / restore incompatibility
--------------------------------------
* rrdtool dump 1.3 does emit completely legal XML. Basically this
means that it contains an XML header and a DOCTYPE definition.
Unfortunately this causes older versions of rrdtool restore to be
unhappy.
* To restore a new dump with an old rrdtool restore version, either
remove the XML header and the doctype by hand (both on the first
line of the dump) or use rrdtool dump --no-header.
The pwd command for server mode was added. Logarithmic graphs were revisited. GPRINT can now access the time component of VDEF values. DNAN and DINF are much faster through caching. Many bugs were killed.
Major Changes between 1.0.x and 1.2.x
Graphing
--------
* rewritten graphics generation based on libart.
- anti-aliased output
- alpha transparency support
- truetype fonts
* additional graphics formats: EPS, PDF, SVG
* extended multi-part documentation
* VDEF support; define and use variables. Find, and use, the
maximum rate seen by rrdtool; compute and show the average
* Sliding window (trend) analysis
Compute a smoother average, for instance over the last 6 CDPs
* percentile (95th or other)
Remove peaks, 95 percent of all rates are at or below the returned value
Logging
-------
* a second logging interface: rrdtool updatev
Verbose updating of the database; show CPDs being created
* Aberrant Behavior Detection with Holt-Winters Forecasting
Compare current data with expected data, detect and log when
the rates are outside expected levels
* COMPUTE data type for artificial data-sources calculating their
input using RPN math and data from the other data-sources.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
Packages changes: use buildlink2 and perl5/module.mk, documentation
splitted in $PREFIX/share/doc/{rrdtool,html/rrdtool}/*.
