- added 7zip parser
- added 'text/sgml' to realtime parseable mimetypes (sometimes returned by the mime type parser)
- added new cached output stream class, very suitable for parsers because of limited memory

automatically aquire release information from download archives
web pages from latest.yacy-forum.net and yacy.net are retrieved, parsed,
links wihin are analysed, sorted and the most recent developer and main
releases are provided as direct download link on the status page, if it was
discovered that a more recent version than the current version is available.
This process is done only once during run-time of a peer, to protect our
download archives from DoS by YaCy peers.

to search procedure. This function can currently not used through the
search interface, but only through remote search.
added accumulation of search attributes to enable the audio, video,
image and application selection.
fixed a problem with external URL representation generation

- added new sentence parser to condenser
- sentence parsing can now handle charsets
to do: charsets must be handed over to new sentence parser
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2712 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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

*) 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
- new class htmlFilterInputStream.java which allows to pre-analyze the html header to extract
the charset meta data. This is only enabled for the crawler at the moment. Integration into
proxy needs more testing.
- adding eventlisterner interfaces to the htmlscraper to allow other classes to get informed
about detected tags (used by the htmlFilterInputStream.java)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2624 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

*) htmlFilterContentScraper.java: using proper charset for document title
*) serverByteBuffer.java: adding new toString which allows to specify the charset for byte encoding
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2593 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2473 6c8d7289-2bf4-0310-a012-ef5d649a1542
This shall be seen as an experiment to exclude all cases where
there could be a DNS lookup during URL comparisment.

- dbImporter threads are now shutdown by the switchboard on server shutdown
- adding possibility to pause a importer thread via GUI
- Bugfix for abort function
See: http://www.yacy-forum.de/viewtopic.php?p=13363#13363
*) Modification of content parser configuration
- now it's possible to configure which parsers should be enabled for the proxy,
crawler, icap, etc. separately
-
*) htmlFilterContentScraper.java
- adding regular expression to normalize URLs containing /../ and /./ parts
*) httpc.java
- adding functionality to unzip gzipped content
- requested by roland: should be used later to allow gzipped seed lists
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1170 6c8d7289-2bf4-0310-a012-ef5d649a1542
- restructuring of mimeTypes based on the parsers
- displaying parser usage count
- displaying human readably parser names
- displaying parser version information
*) httpdFileHandler.java
- adding possibility to support "streaming" servlets
which are special servlets that can communicate with
the client via the connection streams autonomous
- the name of these new servlet types must end with the
file extension .stream
- this feature will be needed by the yacy ScreenSaver
class to fetch statistic data from the peer without the
need to reconnect to the server all the time
*) Adding human readable names and version information for
all supported parsers
*) plasmaParser.java
- adding new structure to store parser statistic data
*) Adding openDocument parser
- can be used to parse odt files
*) jmimemagic
- adding rules to detect openDocument formats properly
*) serverLog.java
- adding functions that can be used to query if a given
logging level is enabled or not.
