The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)

pass value as byte[], not as String. This should cause that less
byte[] <-> String conversions are made during time-critical tasks.
This redesign is not yet complete, more to come ..

all operations on YaCy in a database that should make it possible
1) to re-create a setting on fresh peers
2) to transmit a setting from one peer to another
3) to re-create crawl starts after a complete deletion of the index
This functionality will also support
4) scheduled re-crawls (new implementation)
To implement this, a new database structure has been crated that stores maps into blob heaps. to encode maps the b-encoding technique was used (this is the same encoding that torrent files use)
- added a b-encoder
- enhanced the b-decoder
- added a b-encoded map heap data structure
- added a table organisation based on b-encoded heaps
- added a servlet to maintain such tables (see Tables_p.html)
- integrated the servlet into the Advanced Settings menu
- added an api recording based on the new tables

- fixes for bad equals() methods that had not been used by hash maps and therefore some classes did not work as objects in hash maps.
- this may also affect some cases where double-checks should have been, but did not work.

- fixes for numerous other problems
- removed dead code
- resdesign of the strings-method, which produces now less memory overhead and may help to prevent OOMs
- another fix for the deadlock problem in SplitTable

- 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.

topics will now only be computed using the document title, not the document url,
because the host navigator is now responsible for statistical effects of urls.

- fixed too early computation of navigation
- moved navigation rendering to yacysearchtrailer
- added more asserts

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.

- during index joins all word positions are maintained: better ranking for word distance possible; exact phrase match can be implemented soundly

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.

- two different computations (but mathematical equivalent) of the DHT distance had been consolidated
- moved from 0.0 .. 1.0 double-range position computation to 0 .. Long.Max range for DHT targets
- added fast Long - to - hash computation
- high-precision target computation of gaps for new peers
- added new target computation for horizontal and vertical DHT targets (not yet in use)
- old horizontal-only DHT targets will be upwards compatible to new horizontal and vertical DHT positions

- removed all old resourceInfo classes that handled this distinction
- introduced a new distinction between http request and http response objects
- unified new response objects with two other object types that had been introduced elsewhere
- changed all servlet call methods to use the new http request header object type
- divided static object keys for http header properties into request and response types
- refactoring here and there (a large number of type changes and many methods merged/moved)

- 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)

the most important fix was the addition of the yacybot user-agent for robots.txt loading,
because web masters look for that access to see if the crawler behaves correctly.

- added configuration for these deltas in performance queues
- enhanced performance setting computation (more time for indexing queue for a faster flush
- remote crawling is now enabled during local crawling if indexer has space and time for more links
- added database stub for new distributed file system
- refactoring of time computation to get an abstraction level that will be used by a TTL rule in new distributed file system

- prevention of false information of own IP address
- enabled searching before an own IP address is assigned (before first ping happened)
- removed warning about limited search function
- added better time-out settings for peer-ping process (10 seconds complete, 5 seconds for back-ping)

A large refactoring was neccessary
- added another crawl start option: automatic restriction to sub-path
- removed crawlStartSimple and renamed crawl start expert
to crawl start (without expert)
- some changes to texts in crawl start
- added some more deletions when an web index is deleted:
delete also queues and robots cache

from the ConfigNetwork online interface
- to make this possible, a large refactoring and reorganisation of data structures was necessary
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4803 6c8d7289-2bf4-0310-a012-ef5d649a1542
This change is inspired by the need to see a network connected to the index it creates in a indexing team.
It is not possible to divide the network and the index. Therefore all control files for the network was moved to the network within the INDEX/<network-name> subfolder.
The remaining YACYDB is superfluous and can be deleted.
The yacyDB and yacyNews data structures are now part of plasmaWordIndex. Therefore all methods, using static access to yacySeedDB had to be rewritten. A special problem had been all the port forwarding methods which had been tightly mixed with seed construction. It was not possible to move the port forwarding functions to the place, meaning and usage of plasmaWordIndex. Therefore the port forwarding had been deleted (I guess nobody used it and it can be simulated by methods outside of YaCy).
The mySeed.txt is automatically moved to the current network position. A new effect causes that every network will create a different local seed file, which is ok, since the seed identifies the peer only against the network (it is the purpose of the seed hash to give a peer a location within the DHT).
No other functional change has been made. The next steps to enable network switcing are:
- shift of crawler tables from PLASMADB into the network (crawls are also network-specific)
- possibly shift of plasmaWordIndex code into yacy package (index management is network-specific)
- servlet to switch networks

- renamed also the plasmaCrawlResults to have a consistent naming for url and image queues
- added a double-check for the images
- added additional queues for the images: all worse-quality images go there, so the queue can be used also if no sizes are given; no image is lost
- added a cleanup for the stacks so they cannot flood the memory
