- increased sort limit, now 3000 entries, before: 1000
this should cause that more results can be shown in case
of strong limitating constraints, like domain navigation
- enhanced the sort process
- check against domain navigator bugs
- fix in sort stack
- showing now all naviagtion pages at first search (not only next page)

This is a major change in the organization of indexes.
Please consider a back-up of your data before you run this update.
All existing index files will be moved and renamed to a new position.
With this change, it will be possible to maintain different indexes for different purposes and it will be possible to have a distinction between DHT-in and DHT-out specific indexes. Tenants may also have their own index, and it may be possible to have histories and back-ups of indexes. This is just the beginning, many servlets must be adopted after this change, but all functions that had been there should still work.

- limit comparisment to only the first 10 elements that had been sorted before without IO
- added a size cache to index computation because the size is computed at least twice in set comparator

this is the beginning of some architecture changes that will hopefully bring some more stability, speed and transparency to the search process.

- removed the plasma package. The name of that package came from a very early pre-version of YaCy, even before YaCy was named AnomicHTTPProxy. The Proxy project introduced search for cache contents using class files that had been developed during the plasma project. Information from 2002 about plasma can be found here:
http://web.archive.org/web/20020802110827/http://anomic.de/AnomicPlasma/index.html
We stil have one class that comes mostly unchanged from the plasma project, the Condenser class. But this is now part of the document package and all other classes in the plasma package can be assigned to other packages.
- cleaned up the http package: better structure of that class and clean isolation of server and client classes. The old HTCache becomes part of the client sub-package of http.
- because the plasmaSwitchboard is now part of the search package all servlets had to be touched to declare a different package source.

- The indexing queue was a historic data structure that was introduced at the very beginning at the project as a part of the switchboard organisation object structure. Without the indexing queue the switchboard queue becomes also superfluous. It has been removed as well.
- Removing the switchboard queue requires that all servlets are called without a opaque generic ('<?>'). That caused that all serlets had to be modified.
- Many servlets displayed the indexing queue or the size of that queue. In the past months the indexer was so fast that mostly the indexing queue appeared empty, so there was no use of it any more. Because the queue has been removed, the display in the servlets had also to be removed.
- The surrogate work task had been a part of the indexing queue control structure. Without the indexing queue the surrogates needed its own task management. That has been integrated here.
- Because the indexing queue had a special queue entry object and properties attached to this object, the propterties had to be moved to the queue entry object which is part of the new indexing queue withing the blocking queue, the Response Object. That object has now also the new properties of the removed indexing queue entry object.

high-performance search query situations as seen in yacy-metager integration showed deadlock situation caused by synchronization effects inside of sun.java code. It appears that the logger is not completely safe against deadlock situations in concurrent calls of the logger. One possible solution would be a outside-synchronization with 'synchronized' statements, but that would further apply blocking on all high-efficient methods that call the logger. It is much better to do a non-blocking hand-over of logging lines and work off log entries with a concurrent log writer. This also disconnects IO operations from logging, which can also cause IO operation when a log is written to a file. This commit not only moves the logger from kelondro to yacy.logging, it also inserts the concurrency methods to realize non-blocking logging.

- added &meanCount= to query string
- &meanCount=0 ==> no suggestion, no performance loss

- by default the navigator computation if off for servlet yacysearch.html, but:
- the servlet is called by default with a option to switch navigator results on
this will prevent that metasearch users will get slow results that are caused by unnecessary computations

- added a analysis method that counts bytes that could be saved in case the new HandleMap can be applied in the most efficient way. Look for the log messages beginning with "HeapReader saturation": in most cases we could save about 30% RAM!
- removed the old FlexTable database structure. It was not used any more.
- removed memory statistics in PerformanceMemory about flex tables and node caches (node caches were used by Tree Tables, which are also not used any more)
- add a stub for a steering of navigation functions. That should help to switch off naviagtion computation in cases where it is not demanded by a client

divided that class into three parts:
- the peers object is now hosted by the plasmaSwitchboard
- the crawler elements are now in a new class, crawler.CrawlerSwitchboard
- the index elements are core of the new segment data structure, which is a bundle of different indexes for the full text and (in the future) navigation indexes and the metadata store. The new class is now in kelondro.text.Segment
The refactoring is inspired by the roadmap to create index segments, the option to host different indexes on one peer.

- refactoring: migrated data objects for the new connector classes
- added a DAO interface class to specify an abstract interface for database retrieval connector methods

- after a search is started, it is analysed how many hits are in each site
- this can be done really efficient, because the navigation information is hidden in the url hash and can be computed very fast
- the search result shows a column on the right with the hosts and the hits per host
- after a click on a host the search is modified using the efficient site: - operator

- modified result page rendering to use new icons instead of numbers
- set different default values in yacy.init for higher indexing performance; removed pro-values
- modified WatchCrawler to accept 30000 PPM instead of only a maximum of 6000 PPM

"site:" uses fast site operator introduced in r5770

terms (words) are not any more retrieved by their word hash string, but by a byte[] containing the word hash.
this has strong advantages when RWIs are sorted in the ReferenceContainer Cache and compared with the sun.java TreeMap method, which needed getBytes() and new String() transformations before.
Many thousands of such conversions are now omitted every second, which increases the indexing speed by a factor of two.

This is a preparation to introduce other index tables as used now only for reverse text indexes. Next application of the reverse index is a citation index.
Moved to version 0.74
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5777 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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.

in the network configuration, you can configure a whiteliste and a blacklist
- blacklistet clients cannot search
- whitelistet client get never any search restrictions
- for all other clients: apply DoS search restrictions
Please see the example configuriation in yacy.network.freeworld.unit
by default, all clients from localhosts get whitlistet.
If you have your own YaCy network, please put all the IPs of your peers into the whitelist

- added dummy servlet class, because otherwise the template engine is not triggered.
thats so because the yacy httpd works much faster as normal file server without a scan
of the served pages. Therefore each page with templates must now have a class file associated to it.
- fixed json output format of yacysearch
