- refactoring of plasmaParserDocument to use Dublin Core - compatible property names
- redesign of url handling in parser and condenser (less String-to-yacyURL conversion)
- more generics
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4352 6c8d7289-2bf4-0310-a012-ef5d649a1542
search profiling showed, that a major amount of time is wasted by computing url hashes. The computation does an intranet-check, which needs a DNS lookup. This caused that each urlhash computation needed 100-200 milliseconds, which caused remote searches to delay at least 1 second more that necessary. The solution to this problem is to attach a URL hash to the URL data structure, because that means that the url hash value can be filled after retrieval of the URL from the database. The redesign of the url/urlhash management caused a major redesign of many parts of the software. Since some parts had been decided to be given up they had been removed during this change to avoid unnecessary maintenance of unused code.

- 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

- 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

This shall be seen as an experiment to exclude all cases where
there could be a DNS lookup during URL comparisment.

a) renaming the parent folder in the tgz file to yacy
(can be configured via build properties file)
b) reconfiguring build file to throw an error if a file
name is too long
Please note that currently there is _no_ proplem with too long
class names because of step a.

- 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.

optional content parsers, thread pool configuration ...
Please help me testing if everything works correct.
*) Migration of yacy seedUpload functionality
See: http://www.yacy-forum.de/viewtopic.php?t=256
- new uploaders can now be easily introduced because of a new modulare uploader system
- default uploaders are: none, file, ftp
- adding optional uploader for scp
- each uploader provides its own configuration file that will be
included into the settings page using the new template include feature
- Each uploader can define its libx dependencies. If not all needed libs are
available, the uploader is deactivated automatically.
*) Migration of optional parsers
See: http://www.yacy-forum.de/viewtopic.php?t=198
- Parsers can now also define there libx dependencies
- adding parser for bzip compressed content
- adding parser for gzip compressed content
- adding parser for zip files
- adding parser for tar files
- adding parser to detect the mime-type of a file
this is needed by the bzip/gzip Parser.java
- adding parser for rtf files
- removing extra configuration file yacy.parser
the list of enabled parsers is now stored in the main config file
*) Adding configuration option in the performance dialog to configure
See: http://www.yacy-forum.de/viewtopic.php?t=267
- maxActive / maxIdle / minIdle values for httpd-session-threadpool
- maxActive / maxIdle / minIdle values for crawler-threadpool
*) Changing Crawling Filter behaviour
See: http://www.yacy-forum.de/viewtopic.php?p=2631
*) Replacing some hardcoded strings with the proper constants of the httpHeader class
*) Adding new libs to libx directory. This libs are
- needed by new content parsers
- needed by new optional seed uploader
- needed by SOAP API (which will be committed later)
