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.

With soLinger=true the httpd looses connections
The effect can be seen when crawling the internal repository:
lost connections filled the client process queue until it was full
and no more connections were possible.

- some hacks for less memory usage:
-- less usage of buffer and cache memory in EcoFS
-- buffer allocation on-demand in BufferedIOChunks
-- removed largest ybr idx

- after a index selection is made, the index is splitted into its vertical components
- from differrent index selctions the splitted components can be accumulated before they are placed into the transmission queue
- each splitted chunk gets its own transmission thread
- multiple transmission threads are started concurrently
- the process can be monitored with the blocking queue servlet
To implement that, a new package de.anomic.yacy.dht was created. Some old files have been removed.
The new index distribution model using a vertical DHT was implemented. An abstraction of this model
is implemented in the new dht package as interface. The freeworld network has now a configuration
of two vertial partitions; sixteen partitions are planned and will be configured if the process is bug-free.
This modification has three main targets:
- enhance the DHT transmission speed
- with a vertical DHT, a search will speed up. With two partitions, two times. With sixteen, sixteen times.
- the vertical DHT will apply a semi-dht for URLs, and peers will receive a fraction of the overall URLs they received before.
with two partitions, the fractions will be halve. With sixteen partitions, a 1/16 of the previous number of URLs.
BE CAREFULL, THIS IS A MAJOR CODE CHANGE, POSSIBLY FULL OF BUGS AND HARMFUL THINGS.

* added possibility to find maximum possible heap size
you can get it via getWin32MaxHeap.bat
this may cause high system load
moreover the found limit is no guarantee for stable startups since it depends on system configuration

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
