- added a memory limitation in the zip parser and the pdf parser
- added a search throttling: if there are too many search queries are still to be computed, then new requests are not accepted for some time. if after a one second still no space is there to perform another search, the search terminates with no results. this case should only happen in case of DoS-like situations and in case of strong load on a peer like if it is integrated in metager.
- added a search cache deletion process that removes search requests in case that throttling happens

used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

- many speed/performance hacks
- added solr charding and new charding web interface
- added option to switch off the yacy index when using solr
- added new fail-url categories which are used to make a distinction which fail-urls to be sent to solr
- refactoring/renaming of some method names to distinguish host/url hashes better
- a large number of bug/npe fixes

This time it works like this:
- each peer provides its ranking information using the yacy/idx.json servlet
- peers with more than 1 GB ram will load this information from all other peers, combine that into one ranking table and store it locally. This happens during the start-up of the peer concurrently. The new generated file with the ranking information is at DATA/INDEX/<network>/QUEUES/hostIndex.blob
- this index is then computed to generate a new fresh ranking table. Peers which can calculate their own ranking table will do that every start-up to get latest feature updates until the feature is stable
- I computed new ranking tables as part of the distribition and commit it here also
- the YBR feature must be enabled manually by setting the YBR value in the ranking servlet to level 15. A default configuration for that is also in the commit but it does not affect your current installation only fresh peers
- a recursive block rank refinement is implemented but disabled at this point. it needs more testing
Please play around with the ranking settings and see if this helped to make search results better.

- added more properties to solr index
- refactoring
- more constants in switchboard
- fix for some NPEs
- recognition of more images
- removed synchronization in HandleMap (obviously not necessary?)
- added a nolocal configuration to remove excessive dns lookup (works only on allip - default off). Indexes produced with this setting are all flagged with 'local' and are (on purpose) not usable for freeworld because they will be rejected as beeing local.

- new concurrent score map using atom operation from java concurrency classes
- redesigned difference beween StaticScore and Dynamic Score into ScoreMap and ReversibleScoreMap allowed that many classes can now use simple ScoreMap Objects which can be used better in concurrent environments using the ConcurrentScoreMap
- switched from DynamicScore to ConcurrentScoreMap usage wherever possible

- added more instances of formatter objects to different classes to make them independent in case of lockings that may applay during synchronization of the date formatter object (date formatting is not thread-safe and must be synchronized therefore)

- added use of LookAheadIterator which should prevent mistakes when coding iterators with embedded iterators
- added a fail-safe reaction in case of database corruption using iterators over database elements (no interruption then)

- added some clear statements that shall clear static cache size within the pdfbox library
- the pdfbox library contains a memory leak; it is unsafe to run a peer with pdf parser permanently on.

- rss feeds in scheduler
The first list has a button that can be used to place rss feeds into the scheduler
The second list has a button to delete rss feeds from the scheduler

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)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7071 6c8d7289-2bf4-0310-a012-ef5d649a1542
the BEncodedHeap now implements Map<byte[], Map<String, byte[]>>
This will make it possible that also different database storage types may be added that implement also the same Map<byte[], Map<String, byte[]>> interface.

- move the header framework classes to cora
- move the ARC caching classes to cora
- refactoring of code to call these classes from cora
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7068 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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

- added recording date, last execution date and next execution date for a scheduler (scheduler to be implemented next)
- 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)
- simplified database back-end (not so much specialized methods for multiple properties)
- extended date formatter to produce a special format to show dates in html ( in spaces of date format)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7049 6c8d7289-2bf4-0310-a012-ef5d649a1542
- confirm that database objects that are not supposed to grow do not have a index memory management that is designed for growth
- changed index sorting method in such a way that it allocates less objects during quicksort
- database classes classes renaming (shorter, naming addresses that objects hold in RAM)
- added a large number of asserts to check if objects actually take the RAM that they should have
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7019 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added statistics about database index caches in PerformanceMemory_p.html
- adoped many classes to use the new statistics
- added missing close statements

- fix for initial generation of crawl profiles (one more reason to remove your crawl profiles)
- more String -> byte[] migration
- more logging for cache store/hit

- added crawling queue sizes to /api/status_p.xml, syntax same as in queues_p.html
- fixed a bug in queue enumeration that caused a out of bounds exception
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6842 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6823 6c8d7289-2bf4-0310-a012-ef5d649a1542
- removed usage of URL-Caches which could have been a memory leak
- removed unused classes and methods
- removed not necessary synchronizations
- added synchronization hacks where possible
- 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
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6820 6c8d7289-2bf4-0310-a012-ef5d649a1542
The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6815 6c8d7289-2bf4-0310-a012-ef5d649a1542
This should speed up RWI cache dump and RWI merge operations and should cause less blocking time during these processes for the indexer.

- added 'select all' feature in Tables_p
- enhanced ViewFile.html: has now an input field to load arbitrary resources from the web and analyze them (!!!)

- show in ViewFile if ressource is in url-db and/or in Web cache
- bugfixes to BEncodedHeap and Tables management
