- 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

*) 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

*) 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.

This is buildconfigureable by changing the extensionTarget Property in the build.properties file
*) Trying to solve "yacy.java template replacement / ant build failed" bug

*) automatically adding SVN Revision number to tar file name
*) introducing build.properties file that can be used to set the build version number and date

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)

- now the ant build file has the same functionality as the makerelease build file
- from now on the ant build files can be used instead of the makerelease build script
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@84 6c8d7289-2bf4-0310-a012-ef5d649a1542
- each additional parser must be in a subpackage
of plasma.parser
- each parser must have its own ant build file (which will
be called automatically from the main build file)
- Calling the main build file results in building a separate
zip file for each optional parser. This zip file includes:
+ sources of the Parser.java
+ compiled classes of the Parser.java
+ needed additional libs (libx)
- To install an additional parser the user simply needs to
extract the zip file listed above into his/her yacy directory.
- The configuration (enabling/disabling) of a parser can be done
via the webinterface (currently the settings dialoge) and is
done "on-the-fly". The installation can not be done "on-the-fly"
at the moment because of classpath issues.
- The classpath of the linux startup/stop scripts is generated
automatically now (including all libraries from lib and libx).
*) Bugfix: File Extension was not calculated correctly by the crawler
e.g.: file extension was accidentally: .php?param=value
Corrected.
*) Adding additional parser for parsing of rss/atom feeds
- added needed libs to do this.
TODO:
- automatic building classpath for windows startup scripts
