- re-designed remote request result processing
- re-designed local result accumulation, will be further enhanced with snippet fetcher
- removed search process handling in switchboad
- made snippet class static (there is no need for multiple snippet objects)
- removed some redundant tasks in server-side search process, should be a little bit faster now

target servers had been able to see search words from the referrer of the favicon fetch.
This has been removed by using the getImage - servlet for favicon fetch.
Since java does not support loading of bmp and ico-Images, such parsers had been added.
The image parser had been coded from their original microsoft documentation.
This influences also the image-search functionality: there can now be a preview
of found bmp-images. Another benefit: favicons for search results are now cached with the HTCACHE.

- the general NURL-index for all crawl stack types was splitted into separate indexes for these stacks
- the new NURL-index is managed by the crawl balancer
- the crawl balancer does not need an internal index any more, it is replaced by the NURL-index
- the NURL.Entry was generalized and is now a new class plasmaCrawlEntry
- the new class plasmaCrawlEntry replaces also the preNURL.Entry class, and will also replace the switchboardEntry class in the future
- the new class plasmaCrawlEntry is more accurate for date entries (holds milliseconds) and can contain larger 'name' entries (anchor tag names)
- the EURL object was replaced by a new ZURL object, which is a container for the plasmaCrawlEntry and some tracking information
- the EURL index is now filled with ZURL objects
- a new index delegatedURL holds ZURL objects about plasmaCrawlEntry obects to track which url is handed over to other peers
- redesigned handling of plasmaCrawlEntry - handover, because there is no need any more to convert one entry object into another
- found and fixed numerous bugs in the context of crawl state handling
- fixed a serious bug in kelondroCache which caused that entries could not be removed
- fixed some bugs in online interface and adopted monitor output to new entry objects
- adopted yacy protocol to handle new delegatedURL entries
all old crawl queues will disappear after this update!

- redesign of data storage in plasmaSearchRankingProfile
- profiles are extended by new ranking parameters
- new RWI ranking parameters are considered during ranking
- appearance attributes (i.e. emphasised text) is now considered
- faster ranking
- some attributes that had been checked during post-ranking can now be
checked during pre-ranking phase
- removed old ranking parameter on index.html page (will be replaced by profiles in the future)
- ranking can now consider appearances of media content
- snippet-loading for media types now work correctly (fetches only from the wanted media)
- ranking-profiles can be handed over the remote peers and apply there also
- re-search of same query with different domain now also re-triggers remote search

- for each crawl start, there is now a flag for text and media
- the localCrawl flag is superfluous
- added new crawl profiles
- if an image search is done, only media links are crawled for the snippets

- added self-healing to database in case that wrong free-pointers exist
- added presentation of media links in snippets (does not yet work correctly)
- code cleanup

Such constraints may formulate specific restrictions to web searches
This is implemented by scraping information for constraints from a web
page during parsing, and storing flags to the pages within the web index.
In this first step, only information for index pages ("index of", directory listings)
are scraped and stored in flags
- added new flag class kelondroBitfield
- added scraper method in condenser
- added bitfield structure for all scrape types (see also condenser)
- added bitfield structure for appearance locations (see RWIEntry)
- added handover protocol for remote search and index distribution
- extended kelondroColumn class to hold bitfield types
- added another search attribute on search page (index.html)
- extended search-filter to enable filtering of non-matching constraints
- set all new database types to be default
- refactoring: moved word hash generation to condenser class

- moved all url and index(RWI) entries to index package
- better naming to distinguish RWI entries and URL entries

- added test migration method to migrate the old LURL to a new LURL
the new LURL will be splitted into different tables for each month
this solves several problems:
- the biggest table in YaCy is splitted in different parts and can
also be managed in filesystems that are limited to 2GB
- the oldest entries can easily be identified, used for re-crawl und
deleted
- The complete database can be limited to a specific size (as wanted many times)

- snippets will generate an entry in responseHeader.db
- there is now another default profile for snippet loading
- pages from snippet-loading will be indexed, indexing depth = 0
- better organization of default profiles
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2733 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added new sentence parser to condenser
- sentence parsing can now handle charsets
to do: charsets must be handed over to new sentence parser

- method loadResourceContent defined as deprecated.
Please do not use this function to avoid OutOfMemory Exceptions
when loading large files
- new function getResourceContentStream to get an inputstream of a cache file
- new function getResourceContentLength to get the size of a cached file
*) httpc.java:
- Bugfix: resource content was loaded into memory even if this was not requested
*) Crawler:
- new option to hold loaded resource content in memory
- adding option to use the worker class without the worker pool
(needed by the snippet fetcher)
*) plasmaSnippetCache
- snippet loader does not use a crawl-worker from pool but uses
a newly created instance to avoid blocking by normal crawling
activity.
- now operates on streams instead of byte arrays to avoid OutOfMemory
Exceptions when operating on large files
- snippet loader now forces the crawl-worker to keep the loaded
resource in memory to avoid IO
*) plasmaCondenser: adding new function getWords that can directly operate on input streams
*) Parsers
- keep resource in memory whenever possible (to avoid IO)
- when parsing from stream the content length must be passed to the parser function now.
this length value is needed by the parsers to decide if the parsed resource content is to large
to hold it in memory and must be stored to file
- AbstractParser.java: new function to pass the contentLength of a resource to the parsers
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2701 6c8d7289-2bf4-0310-a012-ef5d649a1542
snippet loading. Some access to header-db had been twice and even
more times in some cases. Snippet resource loading fixed.
Furthermore the snippet loading during remote search within the
remote peer has been disabled, but can be switched on remotely by
new flag 'includesnippet=true'

*) better logging of parser failures
*) simplified usage of plasmaparser through switchboard
*) restructuring of crawler
- crawler now returns an error message if it is used in sync mode (e.g. by snippet fetcher)
*) snippet-fetcher: more verbose error messages
*) serverByteBuffer.java: adding new function append(String,encoding)
*) serverFileUtils.java: adding functions to copy only a given number of bytes between streams
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2641 6c8d7289-2bf4-0310-a012-ef5d649a1542
- serverFileUtils.java:
-- adding methods to copy from stream to writer and readers to writers
-- moving httpc writeX methods into serverFileUtils class
- serverCharBuffer.java: removing inheritance from Writer class
- replacing htmlFilterOutputStream by htmlFilterWriter class which handles
content as char stream
- htmlFilterContentTransformer.java: deactivating getText mode
(still needs to be migrated to use char streams instead of byte streams)
- changes in several classes to use htmlFilterWriter instead of htmlFilterOutputStream
- changes in Scraper and Transformer classes to operate on chars instead of bytes
- httpdProxyHandler.java: bugfix. clientTimeout setting was missing in config file
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2617 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added new image 'B' in front of search results for bookmark generation
- added news generation when a public bookmark is added
- the '+' in front of search results has new meaning: positive rating for that result
- added news generation when a '+' is hit

- adding interface class (plasma/crawler/plasmaCrawlWorker.java) for protocol specific crawl-worker threads
- moving reusable code into abstract crawl-worker class AbstractCrawlWorker.java
- the load method of the worker threads should not be called directly anymore (e.g. by the snippet fetcher)
to crawl a page and wait for the result use function plasmaCrawlLoader.loadSync([...])

- conversion of the crawler pool into a keyed object pool
- crawlers are now loaded based on the url protocol (of course works only for http now)
