- 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

- a new news db will be created (news1024.db), the old one (news.db) can be deleted
- peers with too large news payload are not ignored any more (they may have been invisible because they had a too large news payload!)

- crawl lists for each domain now uses a HandleSet which should use less memory than LinkedLists
- but: fill more entries into the domain lists (all available entries)
- fixes to selection criteria (best domain selection)

- it is now possible to crawl the local file system with an intranet peer
- redesign of URL handling
- refactoring: created LGPLed package cora: 'content retrieval api' which may be used externally by other applications without yacy core elements because it has no dependencies to other parts of yacy

- relaxed dublin core parsing: the dc:reference tag may replace dc:identifier if this does not contain a valid url
- parsing of completeRecords number and presentation in the download list of oai import

- now importing OAI-PMH server list fron two sources
- simultanous import from several servers (even > 2000)
- check buttons on OAI-PMH server list to select multiple servers for import start
- it is possible to select all servers at once for import
- imported XML data is gzipped after import from surrogate reader

- 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
- create less connections at maximum (smaller httpc connection pool size)
- create less connections per host (2, standard required by RFC)
- do not start DHT distributions if there are too many open connections
- clear open/idle connections earlier; run cleaner more often
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6839 6c8d7289-2bf4-0310-a012-ef5d649a1542
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.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6824 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
- 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.

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
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 ..

- reverted SVN 6766, this is too dangerous (may cause unexpected memory usage) and should not be necessary
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6773 6c8d7289-2bf4-0310-a012-ef5d649a1542
