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

- added image size as part of parsed text in images
- avoid unnecessary error messages if parsing of documents failed but one succeeded

- added BEncodedHeap class that encodes B data structures and stores that to a heap
- refactoring of MapView, this is now named MapHeap to fit into the naming scheme of the BEncodedHeap

- 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)

- moved all index generation servlets to it's own main menu item, including proxy indexing
- removed external index import because this operation is not recommended any more. Joining an index can simply be done by moving the index files from one peer to the other peer; they will be merged automatically
- fix to prevent endless loops when disconnecting http sessions
- fix to prevent application of bad blacklist entries that can cause a 'Dangling meta character' exception

old index blobs where deletions have been made because of DHT transmission should be melted down to new blobs. This uses sixcoolers methods from the forum thread but modifies the process in such a way that the blobs are not merged with themselves but simply rewritten to smaller files.

These classes can be used to produce an abstract worker process that can be used for common problems in artificial intelligence, such as game playing and problem solving. These classes will be used as abstraction layer for a new search process in YaCy. These classes had been created while searching for an abstraction of the current search process. It turned out that the abstraction of the YaCy search process is also an abstraction for problems in artificial intelligence and therefore the classes had been designed in such a way that it covers not only the YaCy-specific problem but also the more generic problems in ai. To test the classes they had been used in a ConnectFour implementation (game playing).
