- 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

- better errorhandling
- adding support for outgoing transfer- and content-encoding
- avoid holding outgoing messages into memory before sending them

- 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

- 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
Extracted text of files that are larger than 5MB is stored in a temp file instead of keeping it in memory
*) plasmaParserDocument.java; getText now returnes an inputStream instead of a byte array
*) plasmaParserDocument.java: new function getTextBytes returns the parsed content as byte array
Attention: the caller of this function has to ensure that enough memory is available to do this
to avoid OutOfMemory Exceptions
*) httpd.java: better error handling if the soaphander is not installed
*) pdfParser.java:
- better handling of documents with exotic charsets
- better handling of large documents
- better error logging of encrypted documents
*) rtfParser.java: Bugfix for UTF-8 support
*) tarParser.java: better handling of large documents
*) zipParser.java: better handling of large documents
*) plasmaCrawlEURL.java: new errorcode for encrypted documents
*) plasmaParserDocument.java: the extracted text can now be passed
to this object as byte array or temp file

- 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

until EOF even if a persistent connection is used
*) httpdByteCountInputStream.java: adding skip method
*) httpHeader.java: adding getCharacterEncoding function
