the home path can now be distinguished between
- data home; the path where the DATA directory is created
- application home; everything else
This will make it possible to store application data on Mac releases within the
~/Library/YaCy
directory; a place where Mac applications write their data.
Similar techniques will be possible for debian and windows.
To use the new data path, YaCy can be started with
-start <data path>
or
-gui <data path>

some file types are containers for several files. These containers had been parsed in such a way that the set of resulting parsed content was merged into one single document before parsing. Using this parser infrastructure it is not possible to parse document containers that contain individual files. An example is a rss file where the rss messages can be treated as individual documents with their own url reference. Another example is a surrogate file which was treated with a special operation outside of the parser infrastructure.
This commit introduces a redesigned parser interface and a new abstract parser implementation. The new parser interface has now only one entry point and returns always a set of parsed documents. In case of single documents the parser method returns a set of one documents.
To be compliant with the new interface, the zip and tar parser had been also completely redesigned. All parsers are now much more simple and cleaner in its structure. The switchboard operations had been extended to operate with sets of parsed files, not single parsed files.
additionally, parsing of jar manifest files had been added.

a cache access shall not made directly to the cache any more, all loading attempts shall use the LoaderDispatcher.
To control the usage of the cache, a enum instance from CrawlProfile.CacheStrategy shall be used.
Some direct loading methods without the usage of a cache strategy have been removed. This affects also the verify-option
of the yacysearch servlet. If there is a 'verify=false' now after this commit this does not necessarily mean that no snippets
are generated. Instead, all snippets that can be retrieved using the cache only are presented. This still means that the search hit was not verified because the snippet was generated using the cache. If a cache-based generation of snippets is not possible, then the verify=false causes that the link is not rejected.

so far only search requests at the remote search interface had been counted.
This was done to protect the privacy of searchers, because counting was not done and published at the own search interface.
This caused that no search requests of robinson peers had been counted, becuase they cannot be counted at remote peer.
This change introduces a distinction of locally done search requests at the local search interface from search requests that are on the local interface but had been submitted from a remote IP without authentication.
Now 3 counters are maintained:
- partial count of remote searches
- total count of local searches on robinson peers from non-authenticated clients
- total count of local searches on robinson peers from localhost or authenticated clients
In the global statistic of search requests now the first two counters of the three cases are added
Because we habe a large number of robinson peers with a large number of remote non-authenticated requests the statistic should show at least three times of the number of search requests.

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.

- 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.

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.

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.

- 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.

The old process used a not really efficient way to detect html encoding strings in texts.
