this option was never used and there is also no use to set other columns but the first as the primary key. as a result, access methods to the key do not need to compute key positions, and they work faster.

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.

- log if some File-actions fail (mkdir(), delete(), ...) and some ignored exceptions
- finalized some (more) fields
- finally close some streams
- made inner classes static if not using environment

- moved constants from plasmaSwitchboard to own class (all 232 ;)
- moved remoteProxy-Methods to httpRemoteProxyConfig, better names
- removed some unnecessary code (else-statements)
* formatting (correct indentation)
* minor bugfixes (due to findbugs.sf.net)

- some small enhancements in balancer
- robots parser without references in switchboard
- changes synchronization in robots

- added initial space option for eco tables
- used initial space value in initialization of collectionIndex, this should avoid OOM failures" /Volumes/Magneto/dev/workspace/trunk/source/dbtest.java /Volumes/Magneto/dev/workspace/trunk/source/de/anomic/kelondro/kelondroCollectionIndex.java /Volumes/Magneto/dev/workspace/trunk/source/de/anomic/kelondro/kelondroDyn.java /Volumes/Magneto/dev/workspace/trunk/source/de/anomic/kelondro/kelondroEcoTable.java /Volumes/Magneto/dev/workspace/trunk/source/de/anomic/kelondro/kelondroRow.java /Volumes/Magneto/dev/workspace/trunk/source/de/anomic/kelondro/kelondroSplitTable.java /Volumes/Magneto/dev/workspace/trunk/source/de/anomic/plasma/plasmaCrawlBalancer.java /Volumes/Magneto/dev/workspace/trunk/source/de/anomic/plasma/plasmaCrawlStacker.java /Volumes/Magneto/dev/workspace/trunk/source/de/anomic/plasma/plasmaCrawlZURL.java

This data structure replaces almost all files in the PLASMA directory
also the collection.index and the LURL-db will be created as Eco-DB, if it does not exist before
existing Flex-databases will be used as they are (the is no data lost)
If you want to force the creation of a Eco-collection.index, simply delete the old index.
The Eco file system will only be used if there is enough memory.
The collection.index RAM limit is 200MB, if you have less, a flex-Table is createt.

- added new data structure 'eco' for an index file that should use only 50% of write-IO compared to kelondroFlex
The new eco index is not used yet, but already successfully tested with the collectionIndex
The main purpose is to replace the kelondroFlex at every point when enough RAM is available.
Othervise, the kelondroFlex stays as option in case of low memory (which then can even use a file-index)

- redesign of ordering structures in kelondro (old did not work with strict generics)
- 50% IO reduction during read access on kelondroFlex (ommiting of read on index table)

- more generics
- preparation to extend the balancer for flexible forced delay times
- set different random-access type, should now omit update of metadata in file and could be a bit faster (lets see)

- added chunked file transfer for non-yacy clients
- SSIs are streamed using chunked transfer, partly delivered pages can be seen in browser before transmission is finished
- added client-side network unit identification
- cleaned up code

- some bugs may have been fixed with wrong removal operations
- removed temporary storage of remove-positions and replaced by direct deletions
- changed synchronization
- added many assets
- modified dbtest to also test remove during threaded stresstest

- 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

- 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

- less memory usage
- better usage of awt classes
- drawing abstractions: preparations for movable objects for animation class
- test applet for animations
- known bugs: wrong colours for network picture

- controlled object order for all database tables
- migrated DHT position computation to correct base64-decoded values
this also closed the 'gaps' in the dht positions

this should reduce IO a lot, because write caches are now actived for all databases
- added new caching class that combines a read- and write-cache.
- removed old read and write cache classes
- removed superfluous RAM index (can be replaced by kelonodroRowSet)
- addoped all current classes that used the old caching methods
- more asserts, more bugfixes

- 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)
