- 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

- 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.

- to detect some special formated html documents correctly
- adding rule to detect vCards
*) plasmaParser now supports parsing of files that have a supported fileExtension
but a unsupported mimeType because the webserver has set it incorrectly to text/plain
*) Adding vCard new Parser
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1107 6c8d7289-2bf4-0310-a012-ef5d649a1542
- solving problems with unkown certificates by implementing a dummy trust Manager
- adding https support to robots-parser
- Seed File can now be downloaded from https resources
- adapting plasmaHTCache.java to support https URLs properly
*) URL Normalization
- sub URLs are now normalized properly during indexing
- pointing urlNormalForm function of plasmaParser to htmlFilterContentScraper function
- normalizing URLs which were received by a crawlOrder request
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1024 6c8d7289-2bf4-0310-a012-ef5d649a1542
various checks like the blacklist check or the robots.txt disallow check are now
done by a separate thread to unburden the indexer thread(s)
TODO: maybe we have to introduce a threadpool here if it turn out that this single
thread is a bottleneck because of the time consuming robots.txt downloads
*) improved index transfer
The index selection and transmission is done in parallel now to improve index
transfer performance.
TODO: maybe we could speed up performance by unsing multiple transmission threads in
parallel instead of only a single one.
*) gzip encoded post requests
it is now configureable if a gzip encoded post request should be send on
intex transfer/distribution
*) storage Peer (very experimentell and not optimized yet)
Now it's possible to send the result of the yacy indexer thread to a remote peer
istead of storing the indexed words locally.
This could be done by setting the property "storagePeerHash" in the yacy config file
- Please note that if the index transfer fails, the index ist stored locally.
- TODO: currently this index transfer is done by the indexer thread.
To seedup the indexer
a) this transmission should be done in parallel and
b) multiple chunks should be bundled and transfered together
*) general performance improvements
- better memory cleanup after http request processing has finished
- replacing some string concatenations with stringBuffers
- replacing BufferedInputStreams with serverByteBuffer
- replacing vectors with arraylists wherever possible
- replacing hashtables with hashmaps wherever possible
This was done because function calls to verctor or hashtable functions
take 3 time longer than calls to functions of arraylists or hashmaps.
TODO: we should take a look on the class serverObject which is inherited from hashmap
Do we realy need a synchronization for this class?
TODO: replace arraylists with linkedLists if random access to the list elements is not needed
*) Robots Parser supports if-modified-since downloads now
If the downloaded robots.txt file is older than 7 days the robots parser tries to
download the robots.txt with the if-modified-since header to avoid unnecessary downloads
if the file was not changed. Additionally the ETag header is used to detect changes.
*) Crawler: better handling of unsupported mimeTypes + FileExtension
*) Bugfix: plasmaWordIndexEntity was not closed correctly in
- query.java
- plasmaswitchboard.java
*) function minimizeUrlDB added to yacy.java
this function tests the current urlHashDB for unused urls
ATTENTION: please don't use this function at the moment because
it causes the wordIndexDB to flush all words into the
word directory!

*) Replacing PDFBox 0.7.1 lib with newer version 0.7.2
*) Refactoring of classes httpd/httpc/httpHeaders to
make many methods for httpHeader/Requestline parsing
reusable for new icap implementation
*) adding chunked input stream support
- needed by new icap implementation
- needed by future httpc HTTP/1.1 support
*) httpd.java
- moving all connection property contants to class httpHeader
- moving readHeader function to class httpHeader
- moving parseQuery function to class httpHeader
- moving handleTransparentProxy function to class httpHeader
*) httpHeader.java
- adding new fuction to parse the http response line
- adding new function to converte http headers to a string that
can be send to the client
- adding a function that generates a proper url using all parsed
connection properties
*) ICAP Support
- yacy now supports handling of icap response modification requests
- this feature can be used by other icap enabled proxies to contact
yacy as icap server, and to handover the downloaded content to yacy.logging
for indexing
- functionality was successfully tested with squid 2.5Stable 10 + icap patch
- further icap services e.g. URL filtering based on yacy's blacklists are possible
*) plasmaSwitchboard.java
- htcache entries that are still needed for indexing are now properly registered
as in use after system restart
- extended logging: log message now shows parsing and indexing time for each sb. entry

See: http://www.yacy-forum.de/viewtopic.php?t=516
- removing NIO from server/serverCore.java because of massive problems
with socket close issues
*) Adding support for remote port forwarding via sch
@Orbiter: Please take a look into
- hello.java
- server/serverCore.java.publicIP()
- yacy/yacyClient.java.publishMySeed(...)
*) Making startup loading of additional content parsers more failsafe
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@281 6c8d7289-2bf4-0310-a012-ef5d649a1542
*) bugfix in plasma/plasmaParser.java:
- parsers with missing dependencies wehre not ignored correctly
*) passing a logger instance to the parsers modules which can be used
for logging purposes by the parsers (not done yet)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@276 6c8d7289-2bf4-0310-a012-ef5d649a1542
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)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@126 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
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@78 6c8d7289-2bf4-0310-a012-ef5d649a1542
*) adding content parser for
- pdf (using the pdf-box library)
- doc (using the textmining.org library)
*) adding a Interface for content parsers
*) adding a configuration file which can be used to configure which parser is used for which mimeType
*) Sempahore class was moved and renamed to serverSemaphore
*) Changing yacy shutdown behaviour
Buzy waiting loop for shutdown was removed and replaced with a blocking call (using the semaphore class mentioned above) to the new switchboard.waitForShutdown method.
