- 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 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.

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

- removed never-used secondary crawl depth
- added a must-not-match filter that can be used to exclude urls from a crawl
- added stub for crawl tags which will be used to identify search results that had been produced from specific crawls
please update the yacybar: replace property name 'crawlFilter' with 'mustmatch'.
Additionally, a new parameter named 'mustnotmatch' can be used, which should be by default the empty sring (match-never)

- implemented vertical DHT acceptance ("my own DHT") to accept new targets
- added new target computation for global search: addresses vertical targets also
- enhanced remote crawling: collection of remote crawl urls if queue has less than 100 entries (was: 0 entries)
- better performance value computations for PPM selection in network configuration

with index.storeCommons=false all currently stored commons are deleted!
Default is now 'true', but in future full releases it will be switched to 'false'

- balancer writes cause of robots.txt in log file for crawl delay
- removed log output for forced GC
- smaller RAM flush for RWI cache, should cause more usage of cache and faster crawling

- metadata and results from statistical analysis are compared and result is printed out as debug lines
- added ranking profile for wanted language
- added class with ISO 639 table, a list of all valid country codes that will be used for the language identification

- patched wrong output of language identification (not fixed, only patched!)

- added 'delete all' button to all results of such a domain statistic output which causes that all urls to this domain are deleted
- extended stack cleaner to clean also the statistics: they are not completely destroyed, only the smallest counting domains are removed

- fixed some possible null pointer accesses

- added new storage class for BLOBs. (not used yet, this is half-way to a new structure)

- moved remoteProxy-Methods to httpRemoteProxyConfig, better names
- removed some unnecessary code (else-statements)
* formatting (correct indentation)
* minor bugfixes (due to findbugs.sf.net)

- added default values to crawl deltas in yacy.init
- added configuration for these deltas in performance queues
- enhanced performance setting computation (more time for indexing queue for a faster flush
- remote crawling is now enabled during local crawling if indexer has space and time for more links
- added database stub for new distributed file system
- refactoring of time computation to get an abstraction level that will be used by a TTL rule in new distributed file system

A large refactoring was neccessary
- added another crawl start option: automatic restriction to sub-path
- removed crawlStartSimple and renamed crawl start expert
to crawl start (without expert)
- some changes to texts in crawl start
- added some more deletions when an web index is deleted:
delete also queues and robots cache

from the ConfigNetwork online interface
- to make this possible, a large refactoring and reorganisation of data structures was necessary
