16baa7ad24 To translate a mediawiki dump into the YaCy surrogate format do the following:
- download a wikipedia dump, i.e. dewiki-20090311-pages-articles.xml.bz2
from http://download.wikimedia.org/dewiki/20090311/
- move dewiki-20090311-pages-articles.xml.bz2 to DATA/HTCACHE/
- start the conversion; open a command shell, move to the yacy home directory and execute
java -Xmx2000m -cp classes:lib/bzip2.jar de.anomic.tools.mediawikiIndex -convert DATA/HTCACHE/dewiki-20090311-pages-articles.xml.bz2 DATA/SURROGATES/in/ http://de.wikipedia.org/wiki/

this generates a series of files to DATA/SURROGATES/in

if YaCy is running (it may run concurrently), it fetches all new dumps in the surrogate-in directory. The export process is transaction-save, that means YaCy will not start reading a dump while the dump is not completely finished.

c8624903c6 full redesign of index access data model:
terms (words) are not any more retrieved by their word hash string, but by a byte[] containing the word hash.
this has strong advantages when RWIs are sorted in the ReferenceContainer Cache and compared with the sun.java TreeMap method, which needed getBytes() and new String() transformations before.
Many thousands of such conversions are now omitted every second, which increases the indexing speed by a factor of two.

f6d989aa04 added new class RowSetArray which arranges RowSet objects like Elements in a hashtable, but still provides the functionality of sorted enumeration. The new class is now integrated into the ObjectIndexCache, which is the core class to provide index functions to all database files. The new index access is about twice as fast as before. This has strong speed enhancement effects on all parts of YaCy.
The speed of the kelondro indexing class ObjectIndexCache can be compared with Javas standard TreeMap with the main method in IntegerHandleIndex. The result is, that the kelondro indexing needs only 1/5 of the memory that TreeMap uses! In exchange, the kelondro classes are slower than TreeMap, about four (!) times slower. However, this is not so bad because the better use of the memory is a strong advantage and makes it possible that YaCy can maintain such a large number of document (> 50 million) in one peer.

8444357291 added new row interator in kelondro tables files that enumerates rows
without an order by the primary key. The result is a very fast enumeration of the Eco table data structure. Other table data types are not affected.
The new enumerator is used for the url export function that can be accessed from the online interface (Index Administration -> URL References -> Export). This export should now be much faster, if all url database files are from type Eco
The new enumeration is also used at other functions in YaCy, i.e. the initialization of the crawl balancer and the initialization of YaCy News.

01b97ef3f8 added new cybertag-tracking feature that was inspired by itgrl
from the forum discussion in
http://forum.yacy-websuche.de/viewtopic.php?p=12612#p12612

The feature will provide two basic entities:
- you can integrate image links which point to your yacy installation anywhere in the web.
  the image can be loaded with
  <img src="http://<yourpeer>:<yourport>/cytag.png?icon=invisible&nick=<yournickname_or_community_id>&tag=<anything>">
  This will place a invisible 1-pixel image. If you change the icon=invisible to icon=redpill, you will see a red pill
  Use this, to track your activity in the web.
- you can view your tracks at
  http://localhost:8080/Tracks.html
- There is a public api to your tracks at
  http://localhost:8080/api/tracks_p.json
  which needs authentication
