this saves about 1 millisecond for each URL reference, which has some good effect
on the search result computation if a word is searched that appears very often
(speed-up of 1 second and more)

- within this context: generalized date format handling
- extended Update interface:
* a version lookup can be triggered manually
* a complete lookup + download + re-boot process can be triggered with one click

- added new system update configuration page
- moved system update from status page to system udate page
- moved shutdown and restart from status page to main menu
- added new configuration properties to yacy.init (not yet actively used)
- added some methods to handle new automatic update process

after downloading a release using the download button on the status page
the user can choose any of the downloaded versions for a update.
this enables also a downgrade to a older version.
when the update button is pushed, yacy terminates, installes the choosen version
and restarts

- 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

- no more contact to yacy.net (no remote superseed any more)
- moved superseed file into new network unit definition

we will provide two different releases in the future, one standard release and one 'pro'-release.
the 'pro'-release contains all additional parsers AND has different default performance values.
The pro-version differs therefore from the previous 'all'-version by this default values.
The pro-configuration is automatically choosen if the libx-folder exists. If a version is once initialized, its configuration stays independently from an existing libx folder.
The ant targets had been changed. There are now 3 different targets to create standard and pro-releases, and one target to upgrade:
- dist: creates a standard release (only, no libx target any more)
- distPro: creates a pro-release (includes the libx)
- distExt: creates a libx-release which includes the libx-folder only. It may be used to upgrade from standard to pro
Furthermore, the naming of 'dev'-releases had been removed.

- catched case when web structure cannot be painted because of too less data
- better logging when balance fails

- all web page parsing operations will now increase a web structure file
- the file is computed in memory and dumped at shutdown-time to PLASMASB/webStructure.map in readable form (not a database)
- the file can be used externally to analyse the link structure of the crawled pages
- the web structure can also be retrieved using a xml-interface at http://localhost:8080/xml/webstructure.xml
- the short-term purpose is the computation of a link-graph image (before linuxtag!)
- a long-term purpose could be a decentralized computation of the citation rank

- the network configuration page shows a new option: robinson clusters
- when a global search is made, all robinson peers are excluded, but:
- robinson peers/clusters that provide peer tags and where search words match
such tags, they are included in global search. Therefore, robinson peers/clusters
support the global yacy network with their indexes, without doin DHT-exchange

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.

- 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

- collections are now hand-over as collection lists to collection index for merge opertations
- collection index lists are separated into 'new' and 'extend' lists
- lists are written separately
- write operations are done into array sets and array indexes. These are now serialized
- write operations into index files are sorted by index;
that means that a R/W head does not need to go forward
and backward, only forward
More enhancements are possible
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@3407 6c8d7289-2bf4-0310-a012-ef5d649a1542
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.
IF ANYTHING GOES WRONG, ALL YOUR DATA IS LOST: PLEASE MAKE A BACK-UP

- the speed was doubled by avoiding read access during the dump
- the speed was dramatically increased at least by factor 10
by using a temporary ram-file where the structures are flushed to
before it is dumped then as a whole byte-chunk to the file system.
The speed enhancements also affects some other parts of the database.

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

- the input remains in the IndexCreation menu point
- after pressing the submit button, the IndexingMonitor is called
- the code for creation of new indexing starts was moved to the indexingMonitor
- Existing crawl profiles can be monitored in the Indexing Monitor
- the code for creation of crawl profile data was shifted from indexing start to indexing monitor
- existing crawl profiles can be deleted on the crawl monitor page

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

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

- more synchronization
- bugfix for remove in collections
- bugfix in kelondroFlex (wrong exception condition!)
