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.

- 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.

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

- fixes to httpd server response header generation

- ensuring that ordered indexes stay ordered during remove
- no unnecessary ordering checks
- better test logic in crawl stacker

The cache is now flushed only for one second every ten seconds. During a crawl the cache
fills up completely, and is only flushed if space is needed for more documents.

this is a migration step to support a new method to store the web index, which will also based on the same data structure. made also a lot of refactoring for a better structuring of the BLOBHeap class.

- added a write buffer to BLOBHeap
- modified the BLOBBuffer (is now only to buffer non-compressed content)
- added content compression to the HTCache
The new read cache will decrease the start/initialization time of BLOB files,
like the HTCache, RobotsTxt and other BLOBHeap structures.

- modified and activated write buffer
- increased cache flush factor
- fixed a problem with deadlocking of indexing process
