- faster generation of index abstract compression during remote search
- less synchronization in IO record reading
- request index abstract generation only if necessary and faster time-out in remote search

- removed read cache from Records data structure because the read cache had no cache hit during search operation
- copied old read-cache class to CachedRecords and the old, now new Records class does not have the cache any more and a code review checked that data structures and synchronization is clean
- removed unnecessary synchronization from Table class during get()

this makes YaCy search results VERY fast for all verify=false search cases
and it enhances the search speed also for all other snippet-fetch cases.
With this change my peer performed 100 Queries Per Second (!!!) while doing 10 queries simultanously (!!!)
in an intranet index of 20000 URLs on my 16-core Mac
Check this yourself by doing:
cd bin
./searchtestmulti.sh
after finishing the run, divide 1000 by the given time per query (which is the qps for one thread)
and then multiply again by 10 (because 10 search threads has been started)

- better crawl star for files paths and smb paths
- added time-out wrapper for dns resolving and reverse resolving to prevent blockings
- fixed intranet scanner result list check boxes
- prevented htcache usage in case of file and smb crawling (not necessary, documents are locally available)
- fixed rss feed loader
- fixes sitemap loader which had not been restricted to single files (crawl-depth must be zero)
- clearing of crawl result lists when a network switch was done
- higher maximum file size for crawler

- better control of number of running search threads
- no time-out waiting time when no ranking feeding takes place

created a WeakPriorityBlockingQueue as special implementation
of a PriorityBlockingQueue with a weak object binding.
- better abstraction of ordering technique
- fixed some bugs according to result numbering (distinguish different counters in Queue)
- fixed a ordering bug in post-ranking (ordering was decreased instead of increased)
- reversed ordering numbering using a reversed ordering. The higher the ranking number the better (now).

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>

Map<byte[], Map<String, byte[]>>
Because such Maps with byte[] keys cannot be stored in hash maps (bad hashing on byte[])
another ARC with comparable Maps has been added
This will make it possible to move the HTCache class 'Cache' into the cora package because that
class may be used either with RAM caches (ARCs) or with file-based caches (BEncodedHeaps)

- the scheduler extends the option for re-crawl timing. Many people misunderstood the re-crawl timing feature because that was just a criteria for the url double-check and not a scheduler. Now the scheduler setting is combined with the re-crawl setting and people will have the choice between no re-crawl, re-crawl as was possible so far and a scheduled re-crawl. The 'classic' re-crawl time is set automatically when the scheduling function is selected
- removed the bookmark-based scheduler. This scheduler was not able to transport all attributes of a crawl start and did therefore not support special crawling starts i.e. for forums and wikis
- since the old scheduler was not aber to crawl special forums and wikis, the must-not-match filter was statically fixed to all bad pages for these special use cases. Since the new scheduler can handle these filters, it is possible to remove the default settings for the filters
- removed the busy thread that was used to trigger the bookmark-based scheduler
- removed the crontab for the bookmark-based scheduler

- every process that is monitored with the API Steering interface can now be scheduled!
- added input methods in Steering interface to set a scheduling time
- added a view on the steering api that shows only crawl jobs inside the Crawl Profile servlet
- added a scheduling call process in the cleanup process handler that triggers the scheduled processes
This causes that the cleanup now also looks for scheduled processes. Such processes are therefore not executed at
the same time as given in the target execution time but they will be executed within the cleanup process time window.

- extended database access methods for more data formats, especially for date insert/retrieval
- extended 'Steering' interface to show new database fields
- migrated Steering to new http client
- extended cora http client to transmit authentication and also added some convenience methods (http response code)

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.

- removed concurrency overhead for small number of index normalizations as it happens during remote search
- removed 'load only parseable' constraint for snippet fetch because some resources may not have any url file extension and these had therefore not been parseable and searcheable since they may become parseable after loading when their mime type is known
- this partly fixes some problems with http://forum.yacy-websuche.de/viewtopic.php?p=20300#p20300 but more changes are necessary to get all expected search results

http://java.sun.com/javase/6/webnotes/trouble/TSG-VM/html/memleaks.html#gbyvh
The finalize method prevents that the memory, used by the objects containing the finalize method, is collected and available for the garbage collector. Instead, the memory allocated by such classes are enqueued to a java-internal finalize queue runner. This slows down all operations that uses a lot of object containing finalize methods.
this fix does not remove all finalize method, but such that may be used for throw-away objects that are allocated many times. This should cause a better run-time performance and less OutOfMemoryErrors

for such cases the delete() operation was introduced which is sometimes much cheaper in operation since it does not need to create objects to hold the removed content and it does not need to read those objects.

- no direct deletion of referenced during search (shifted to time after search)
- bundling of all deletions for the references of a single word into one remove operation
- enhanced remove operation by caring that the collection is stored sorted (experimental)
- more String -> byte[] transition for search word lists
- clean up of unused code
- enhanced memory allocation of RowSet Objects (will use a little bit less memory which was wasted before)

- fine-tuned crawling speed to prevent IO of balancer
- fixed a bug in IODispatcher that may have caused that no merges were done
- reduced number of parameters in very often called methods (compare methods)
- reduced complexity of data structures of now massively used HandleSet class
- reduction of new String() and getBytes() usage / new methods to support this transition

- enhanced the Balancer performance when building new domain stacks using a new Table buffer
- added the new Table buffer BufferedObjectIndex class
- changed order of access to LURL-read (prefereing segment over Crawl Queues) will reduced blocking time on balancer
- fixed PPM setting in Crawler_p servlet (had doubled values)
- reduced synchronization in IndexCell because it is not necessary: reduced blocking during indexing/merging/dumping
- removed did-you-mean cache in IndexCell because that caused too much overhead and more memory usage but was not very useful. This reduced also deadlocks that could be causes when searched are performed during indexing.

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
