- basic protection against start-up problems when database files are corrupted
- auto-delete of not-critical databases during startup when load error occurs
- on-the-fly reset option for all database tables
- automatic on-the-fly reset for seed tables during enumeration exceptions

this shall be used to store a fragment of the index on another physical device,
to split IO load and enhance access speed. The index is splitted in such a way
that the LURLs are stored to the secondary location, and the RWIs to the primary
location. This is especially useful for environments where symbolic links are
not possible and may cause IO access even if there is no write access to the
device which hosts the symbolic link.

The new collection index will be more generalized to support other indexes
i.e. YBR block-rank computation. A clean-up of the many conditions to support
the old database was necessary.

- the general NURL-index for all crawl stack types was splitted into separate indexes for these stacks
- the new NURL-index is managed by the crawl balancer
- the crawl balancer does not need an internal index any more, it is replaced by the NURL-index
- the NURL.Entry was generalized and is now a new class plasmaCrawlEntry
- the new class plasmaCrawlEntry replaces also the preNURL.Entry class, and will also replace the switchboardEntry class in the future
- the new class plasmaCrawlEntry is more accurate for date entries (holds milliseconds) and can contain larger 'name' entries (anchor tag names)
- the EURL object was replaced by a new ZURL object, which is a container for the plasmaCrawlEntry and some tracking information
- the EURL index is now filled with ZURL objects
- a new index delegatedURL holds ZURL objects about plasmaCrawlEntry obects to track which url is handed over to other peers
- redesigned handling of plasmaCrawlEntry - handover, because there is no need any more to convert one entry object into another
- found and fixed numerous bugs in the context of crawl state handling
- fixed a serious bug in kelondroCache which caused that entries could not be removed
- fixed some bugs in online interface and adopted monitor output to new entry objects
- adopted yacy protocol to handle new delegatedURL entries
all old crawl queues will disappear after this update!

- better memory allocation for FlexTable indexes
- splitting between static index and dynamic index (only the dynamic part must grow)
- to enable a merge-iteration of new splittet index, a huge number of classes needed to be adopted for new iterator classes
- added new iterator classes that support cloneable iterators
- adopted all iterator classes to implement cloneable itarators

- each cache can now allocate as much memory as is available
- no more fixed limits
- replaced old performance memory monitor by new one
- added supervision methods as static functions into the classes that provide cache functionality
- steering of ram allocation is done with two simple limits that are ram availability-relative

target: better selection of peer-ping targets, which should enhance stabilization of the net

- this class is replaced by an object that can hold any type of object
- this object must be defined as a class that implements kelondroObjectsEntry
- the kelodroMap is now implemented as kelondroMapObjects

- new search options on search page
- new option in ViewInfo to display all links of a file
- enhanced collection data structure

- removed 'deleteComplete' flag; this was used especially for WORDS indexes
- shifted methods from plasmaSwitchboard to plasmaWordIndex

- added an assortment importer. the old database structures can
be imported with
java -classpath classes yacy -migrateassortments
- modified wordmigration. The indexes from WORDS are now imported
to the collection database. The call is
java -classpath classes yacy -migratewords
(as it was)

Such constraints may formulate specific restrictions to web searches
This is implemented by scraping information for constraints from a web
page during parsing, and storing flags to the pages within the web index.
In this first step, only information for index pages ("index of", directory listings)
are scraped and stored in flags
- added new flag class kelondroBitfield
- added scraper method in condenser
- added bitfield structure for all scrape types (see also condenser)
- added bitfield structure for appearance locations (see RWIEntry)
- added handover protocol for remote search and index distribution
- extended kelondroColumn class to hold bitfield types
- added another search attribute on search page (index.html)
- extended search-filter to enable filtering of non-matching constraints
- set all new database types to be default
- refactoring: moved word hash generation to condenser class

- moved all url and index(RWI) entries to index package
- better naming to distinguish RWI entries and URL entries

- generalized object caching and added new object caching class
- added object caching wherever kelondroTree was used
- added object caching also to usage of kelondroFlex
- added object buffering (a write cache) to NURLs
- added many assert statements; fixed bugs here and there
- added missing close methods to latest added classes

- added test migration method to migrate the old LURL to a new LURL
the new LURL will be splitted into different tables for each month
this solves several problems:
- the biggest table in YaCy is splitted in different parts and can
also be managed in filesystems that are limited to 2GB
- the oldest entries can easily be identified, used for re-crawl und
deleted
- The complete database can be limited to a specific size (as wanted many times)

*)Removed double creation of DATA directory. New warning message in case of insufficient rights.
*) Removed roland-ramthun.de-seedlist temporarily, because of server changes

if the new database is switched on, no 'too big' messages appear,
all the WORDS files can be completely migrated
