redesign for better IO performance
enhanced database seek-time by avoiding write operations at distant
positions of a database file. until now, a USEDC counter was written
at the head-section of a kelondroRecords database file (which is the
basic data structure of all kelondro database files) to store the
actual number of records that are contained in the database. Now, this
value is computed from the database file size. This is either done
only once at start-time, or continuously when run in asserts enabled.
The counter is then updated only in RAM, and written at close of the
file. If the close fails, the correct number can be computed from the
file size, and if this is not equal to the stored number it is a strong
evidence that YaCY was not shut down properly.
To preserve consistency, the complete storage-routine had to be re-written.
Another change enhances read of nodes in some cases, where the data-tail
can be read together with the data-head. This saves another IO lookup during
each DB node fetch.
Includes also many small bugfixes.

- added some settings and statistics for url-fetcher 'server'-mode
- added own stack for fetchable URLs
- added possibility to fill stack via shift from peer's queues, via POST (addurls=$count and url$num=$url) or via file-upload
- added "htroot" to classpath of linux start-script

the field contains now a time in UDC-0 (instead relative to local UDC offset)
this fixes a bug in peer selection, where an iteration over all seeds
ordered by lastseen did not work correctly.
Problems may occur because the new meaning of this field may mix with
the different meaning of that field in older peers

- redesign of data storage in plasmaSearchRankingProfile
- profiles are extended by new ranking parameters
- new RWI ranking parameters are considered during ranking
- appearance attributes (i.e. emphasised text) is now considered
- faster ranking
- some attributes that had been checked during post-ranking can now be
checked during pre-ranking phase
- removed old ranking parameter on index.html page (will be replaced by profiles in the future)
- ranking can now consider appearances of media content
- snippet-loading for media types now work correctly (fetches only from the wanted media)
- ranking-profiles can be handed over the remote peers and apply there also
- re-search of same query with different domain now also re-triggers remote search

- 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)

to search procedure. This function can currently not used through the
search interface, but only through remote search.
added accumulation of search attributes to enable the audio, video,
image and application selection.
fixed a problem with external URL representation generation

- the encoding within the new entry format for binary data was wrong
- the string parser of RWI receive had to be enhanced
added some mor debugging tools
- a target peer for index transfer can now be selected by typing in the peer name
- the RWI result list has an entry counter
enhanced routing
- if communication is between two peers that have the same IP address,
the loopback address 127.0.0.1 is used instead the public IP
to contact the peer

post-parameter url to submit an url directly
- fixed some bugs in text parser (not all parts had been analysed)
- fixed a bug in remote search interface (could not handle constraints)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@3001 6c8d7289-2bf4-0310-a012-ef5d649a1542
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

- enhanced local domain detection
- bugfixing for memory assignment in kelondroFlexSplit
- automatic memory assignment to caches according to available RAM
- bugfixes for details during search process

- 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 settings that are in Basic Settings
- joined pages that belong together
- moved include pages from yacy/ to /

snippet loading. Some access to header-db had been twice and even
more times in some cases. Snippet resource loading fixed.
Furthermore the snippet loading during remote search within the
remote peer has been disabled, but can be switched on remotely by
new flag 'includesnippet=true'

- added new image 'B' in front of search results for bookmark generation
- added news generation when a public bookmark is added
- the '+' in front of search results has new meaning: positive rating for that result
- added news generation when a '+' is hit

there are now two full-controlled caches for incoming indexes:
- dhtIn
- dhtOut
during indexing, all indexes that shall not be transported to remote peers
because they belong to the own peer are stored to dhtIn. It is furthermore
ensured that received indexes are not again transmitted to other peers
directly. They may, however be transmitted later if the network grows.
