search is now done using verify=false (instead of verify=cacheonly) which will cause that much more targets can be found.
This showed a bug where no location information was used from the metadata (and other metadata information) if cache=false is requested. The bug was fixed.
Added also location parsing from wikimedia dumps. A wikipedia dump can now also be a source for a location search.
Fixed many smaller bugs in connection with location search.

the httpclient is required by solrj but no class from solrj is used which references to httpclient-3.1
Instead the YaCy http client library based on the apache http client 4.1 is used using a wrapper class
which is in net.yacy.cora.services.federated.solr.SolrHTTPClient
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7655 6c8d7289-2bf4-0310-a012-ef5d649a1542
YaCy supports now the storage to remote solr indexes.
More federated storage (and search) methods may follow.
The remote index scheme is the same as produced by the SolrCell; see
http://wiki.apache.org/solr/ExtractingRequestHandler
Because this default scheme is used, the default example scheme can be used as solr configuration
This is also the same scheme that solr uses if documents are imported with apache tika.
federated solr storage is switched off by default.
To use this, do the following:
- set federated.service.solr.indexing.enabled = true
- download solr from http://www.apache.org/dyn/closer.cgi/lucene/solr/
- extract the solr (3.1) package, 'cd example' and start solr with 'java -jar start.jar'
- start yacy and then start a crawler. The crawler will fill both, YaCy and solr indexes.
- to check whats in solr after indexing, open http://localhost:8983/solr/admin/
Until now it is not possible to use the solr index to search with YaCy in that solr index.
This functionality is now available for two reasons:
1) to compare the functionality of Solr and YaCy and to compare the search speed
2) to use YaCy as a search appliance for people who need a crawler or other source harvesting methods
that YaCy provides (like dublin core reading, wikimedia dump reading, rss feed reader etc) if people still
want to use solr instead of YaCy.

- added parser for in-text appearing geo-locations
- added geo-locations to rss search result
- added evaluation of metadata-attached geo-locations in yacysearch_location to show search results within a map

"THREADS WITH STATES: LOCK FOR OTHERS"
will show only such threads that lock other threads. This is the 'opposite part' of the blocked threads.
Because that this uses a thread dump that is produced with a kill -3 on the PID of the process and such thread dumps are written by the Java core outside of System.out and Sytem.err it is necessary to read the dump from a log in the file system. Such a log is only written if YaCy is started with startYACY.sh on a linux system. That means:
this feature is only available on linux and Mac OS X if YaCy is started with ./startYACY.sh -l

- new concurrent score map using atom operation from java concurrency classes
- redesigned difference beween StaticScore and Dynamic Score into ScoreMap and ReversibleScoreMap allowed that many classes can now use simple ScoreMap Objects which can be used better in concurrent environments using the ConcurrentScoreMap
- switched from DynamicScore to ConcurrentScoreMap usage wherever possible
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7586 6c8d7289-2bf4-0310-a012-ef5d649a1542
1) if the file is changed for a re-crawl this is not reflected in the steering because it would take the previously uploaded crawl start file
2) browsers do not submit the full path of the selected file even if this path is shown in the input field because of security reasons. There is no work-around or hack to make the submission of the full path possible
- fixed deletion of crawl start point urls in crawl stack and balancer double-check
- fixed a problem with steering self-call (no resolving of localhost)
- added more logging for the crawler to supervise why crawl urls are not taken by the loader
- added a javascript onload-function to select domain restriction in all cases where a crawl is started from a file or from a url
- fixed the restrict-to-domain pattern computation, added a 'www.'-prefix and added this functionality also to a crawl start from file

Reason: if this is not used in StringBody-Class initialization, a default charset name is parsed.
This is a synchronized process and all classes using default charsets synchronize at that point
Synchronization is omitted if this class is used

- added more instances of formatter objects to different classes to make them independent in case of lockings that may applay during synchronization of the date formatter object (date formatting is not thread-safe and must be synchronized therefore)

- less synchronizations
- better speed
..at most important and commonly used classes: http headers, url parsing and html parsing

- filtering out too old peers when reading seed lists (limit is now 240 minutes)
- added concurrent host names resolving in front of the http client because the http client uses the java built-in DNS resolve which is not multithreading-safe (i have seen deadlocks in thread dumps showing that this bug in jdk is still there)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7515 6c8d7289-2bf4-0310-a012-ef5d649a1542

Please see new coments in yacy.network.freeworld.unit for details of the new DHT selection methods.
The number of maximum peers is now not fixed to a specific number but may increase with
- the partition exponent
- the number of redundant peers
- the robinson burst percentage
- the multiword burst percentage
The maximum can then be the number of senior peers (all visible peers).

- some restructuring of the document counting and logging structures was necessary
- better abstraction of CrawlProfiles
- added deletion of logs to the index deletion option (if the index is deleted using the servlets) which is necessary to reset the domain counters for the page limitation
- more refactoring to get the LibraryProvider more clean
- some refactoring of the Condenser class

- cleaned up (removed special code and documentation for 27c3)
- added remote search functions to be used within cora

- better document names
- fixed problem with ftp crawling
- added automatic removal of search results from services that are not online according to the latest network scan: this does not delete the index but just does not show them. after the next network scan when the server is available again, the results are again showed.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7385 6c8d7289-2bf4-0310-a012-ef5d649a1542
- multiple hosts for environment scans can be given (comma-separated)
- each service (ftp, smb, http, https) for the scan can be selected
- the scan result can be accumulated or refreshed each time a network scan is made
- a scheduler was added to repeat a scan and add all found urls to the indexer automatically
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7378 6c8d7289-2bf4-0310-a012-ef5d649a1542
- integrated new parser into loader processes: enrich document parser
- fixed a concurrent modification exception in kelondro iterator
- hand-over of document size from crawler to indexer
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7374 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added information about granted access
- enhanced servlet design
- added submit-feedback (because it is a long-running task)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7372 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added a new queue 'noload' which can be filled with urls where it is already known that the content cannot be loaded. This may be because there is no parser available or the file is too big
- the noload queue is emptied with the parser process which indexes the file names only
- the 'start from file' functionality now also reads from ftp crawler
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7368 6c8d7289-2bf4-0310-a012-ef5d649a1542
- when a site-crawl for ftp sites is now started, then a special directory-tree harvester gets the complete directory structure of a ftp server at once
- the harvester runs concurrently and feeds into the normal crawl queue
also in this:
- fixed the 'start from file' crawl function
- added a link detector for the html parser. The html parser can now also extract links that are not included in <a> tags.
- this causes that a crawl start is now also possible from clear text link files
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7367 6c8d7289-2bf4-0310-a012-ef5d649a1542
when a search fails for a single url because the snippet cannot be generated, then the url reference is deleted from the index. This mechanism was redesign and enhanced. The process now also writes into the work tables into the table searchfl to prepare a re-indexing mechanism.

- enhanced the pdf and torrent parser: better documents titles
- enhanced the ftp client: more time-out time
- fixed bugs in json for search results
- enhanced yacyinteractive.html: added a file type navigator and a download-script generator for search result files
Please have a look at yacyinteractive.html: this will become the hacker-download tool for 27c3!

- renamed YaCys search result modifications keywords for RECENT, NEAR and language: to the blekko slashtag naming scheme. YaCy now supports the following blekko-like slash built-in slashtags:
/date
- for search results ordered by date (most recent up)
/near
- for search results where search words appear near to each other (closest up)
/language/<lang>
- for a sorting by language where the wanted language gets up. Example: /language/de

this was never used and extended in the last years. The resulting YBR ranking criteria
is still a good idea and will be used in the future. Possible generation methods for YBR
ranking are:
- "trust-rank" using the link structure as can be discovered in a single crawl (idea from FSCONS)
- "block-rank" calculated from the local link structure
- a distributed "block-rank" using the xml API to the link structure from other peers

* crawler and search allow only urls matching one in domainlist (if list is provided)
* this may be useful to prevent dedicated networks from being "polluted"
* FilterEngine is improved Backlist-object, Blacklist may inherit from FilterEngine in the future

- faster generation of index abstract compression during remote search
- less synchronization in IO record reading
- request index abstract generation only if necessary and faster time-out in remote search

- removed read cache from Records data structure because the read cache had no cache hit during search operation
- copied old read-cache class to CachedRecords and the old, now new Records class does not have the cache any more and a code review checked that data structures and synchronization is clean
- removed unnecessary synchronization from Table class during get()

this makes YaCy search results VERY fast for all verify=false search cases
and it enhances the search speed also for all other snippet-fetch cases.
With this change my peer performed 100 Queries Per Second (!!!) while doing 10 queries simultanously (!!!)
in an intranet index of 20000 URLs on my 16-core Mac
Check this yourself by doing:
cd bin
./searchtestmulti.sh
after finishing the run, divide 1000 by the given time per query (which is the qps for one thread)
and then multiply again by 10 (because 10 search threads has been started)

- better crawl star for files paths and smb paths
- added time-out wrapper for dns resolving and reverse resolving to prevent blockings
- fixed intranet scanner result list check boxes
- prevented htcache usage in case of file and smb crawling (not necessary, documents are locally available)
- fixed rss feed loader
- fixes sitemap loader which had not been restricted to single files (crawl-depth must be zero)
- clearing of crawl result lists when a network switch was done
- higher maximum file size for crawler

- better control of number of running search threads
- no time-out waiting time when no ranking feeding takes place
- local search queries by a remote peer may be faster up to 300 milliseconds
- a local search may even be faster

This class requests a YaCy peer remotely and produces search result objects.
The class was implemented in such a way that it is as short as possible. To get a
better integration of search results, use the cora package.
This class is fully stand-alone, it does not need any other external library other than already contained in JRE.

- 300 ppm is default now (but this is switched off by default; if you switch it on you may want more traffic?)
- better timing for busy queue
- better amount of remote url retrieval
- better time-out values
- better tracking of availability of remote crawl urls
- more logging for result of receipt sending

- added use of LookAheadIterator which should prevent mistakes when coding iterators with embedded iterators
- added a fail-safe reaction in case of database corruption using iterators over database elements (no interruption then)
