this is a set of search processes that shall enrich search results
with specialized requests to realize a combination of search results
from different peers.

- added generation of a compressed index within remote peers during global search
- added selection of specific urls within remote peers during secondary global search

* cleaned up code
* added unit test code
* migrated ranking RCI computation to kelondroFlex and kelondroCollectionIndex

to store the index entry. This is another step to move to the new database structure.
A side effect of this change is, that index storage uses much less RAM space,
which affects the index RAM cache.

* store() is now called explicitely
* more urls are written to the EURL table
* the EURL stack does not store the complete entry any more, now only the URL hash
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2323 6c8d7289-2bf4-0310-a012-ef5d649a1542
* mainly for the transition to the new indexing database structure
* a bugfix for an endless loop inside kelondroTree iteration
* a bugfix for bulk read inside a kelondroTree iteration; the bug caused that some elements had been iterated twice
* very strong speed enhancement for url/domain extraction

*) new layout for bookmark list
(Allo: please take a look if it's acceptable for you)
*) crawlReceipt.java: displaying peer name in logging message
*) Network.html: adding button for manual peer ping
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1584 6c8d7289-2bf4-0310-a012-ef5d649a1542
- changed index collection process: indexes are not first flushed to indexEntity,
but now collected directly from ram cache and assortments
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1489 6c8d7289-2bf4-0310-a012-ef5d649a1542
- replaced usage of temporary IndexEntity by EntryContainer
- added more attributes to word index
- added exact-string search (using quotes in query)
- disabled writing into WORDS during search; EntryContainers are used instead
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1485 6c8d7289-2bf4-0310-a012-ef5d649a1542
- implemented hand-over of new word index attributes during remote search
- implemented word-distance computation during search
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1382 6c8d7289-2bf4-0310-a012-ef5d649a1542
the kelondro database needs specific information about the order of
base64-encoded keys. Since no other package depends on base64
(only the httpd uses base64 for encryption, but does not need to encode these strings)
it is good to move base64 encoding to the new ordering classes in kelondro.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1284 6c8d7289-2bf4-0310-a012-ef5d649a1542
The location is computed from the userAgent string of connecting peers.
Therefore this information is not available right after start-up.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1241 6c8d7289-2bf4-0310-a012-ef5d649a1542
(no more NULL values are returned, instead, an IOException is thrown)
- removed ugly damagedURLS implementation from plasmaCrawlLURL.java
(this inserted a static value into the Object which is not really a good style)
- re-coded damagedURLS collection in yacy.java by catching an exception and evaluating the exception message
to do:
- the urldbcleanup feature must be re-tested
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1200 6c8d7289-2bf4-0310-a012-ef5d649a1542
next steps: attach voting and restrict to administrator

- we do not know if the URL was stored in the noticeURL-DB with the old or new hash.
therefore we now try to remove the URL from the noticeURL-DB using both hash values

- Bugfix: old dns cache did not handle case insensitive hostnames correctly.
- adding a possibility to set domain name patterns defining hostnames that should not be cached by the httpc dns cache
e.g. borg-300.dyndns.org
This can be done by setting the new httpc.nameCacheNoCachingPatterns property
- using httpc.dnsResolve wherever possible within the sourcecode
[httpd.java,plasmaCrawlStacker.java]
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1044 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
|> Caused by: de.anomic.kelondro.kelondroException: kelondroTree.searchproc: nullpointernull in db '.../urlHash.db'
- if URL existence can not be determined, we request it from the remote peer
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@997 6c8d7289-2bf4-0310-a012-ef5d649a1542
- adding automatic refresh
- accepts new parameter nameLookup which can be used to deactivate
yacy-peer name lookup (because we have problems with this on large seed-dbs)
*) ViewFile
New page that can be used to view
- original content
- plain text content
- parsed content
- parsed sentences
of a webpage specified by there url hash
Mainly for debugging purpose at the moment
*) Robots.txt
Bugfix for if-modified-since usage
TODO: synchronization of downloads to avoid loading the same robots-file
multiple times in parallel by different threads
*) Shutdown
Better abortion of transferRWI and transferURL sessions on server shutdown
*) Status Page
Adding icon to start/stop crawling via status page
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@950 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!

Therefor a test-request was added to the isConnected function to detect broken connections
and to keep open connections alive

- Adding function to manually force peer ping to remote yacy peer
See:Network.html?page=4
- for debugging purpose only!
*) serverAbstractThread.java:
- Adding posibility to notify a server thread via a synchronization object
- this is needed e.g. by the port forwarding feature to send a notification
to the peerPing thread to redo peer-ping with the new ip/port Settings_p.html
*) Port Forwarding Feature (it should work now)
- adding a serverThread which is responsible to detect broken port forwarding
connections and to do reconnect if needed
- serverCore.java: moving port forwarding initialization into a separate function
- adding positility to configure the ssh port
- moving configuration section on the gui into a separate fieldset

peer handshake if either remote port forwarding is not enabled locally or
the clientIP is not equal to any local ip
*) httpdFileHandler.java:
- printout a more verbose errormessage
*) httpc.java
- allowing to deactivate content encoding from outside

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)
