for example search for "passwd /ftp". This can also be done with /http /https and /smb
- fixed some search throttling processes that should protect your peer against search DoS or strong search load
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7794 6c8d7289-2bf4-0310-a012-ef5d649a1542
added another RSS channel "PROXY". the rss feed for peer news filters this channel if there is not an authorized access on that channel
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7792 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added a memory limitation in the zip parser and the pdf parser
- added a search throttling: if there are too many search queries are still to be computed, then new requests are not accepted for some time. if after a one second still no space is there to perform another search, the search terminates with no results. this case should only happen in case of DoS-like situations and in case of strong load on a peer like if it is integrated in metager.
- added a search cache deletion process that removes search requests in case that throttling happens

used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

- many speed/performance hacks
- added solr charding and new charding web interface
- added option to switch off the yacy index when using solr
- added new fail-url categories which are used to make a distinction which fail-urls to be sent to solr
- refactoring/renaming of some method names to distinguish host/url hashes better
- a large number of bug/npe fixes

- less threads for blocking threads
- disable all threads for DHT transmission for networks with zero peers
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7737 6c8d7289-2bf4-0310-a012-ef5d649a1542
This time it works like this:
- each peer provides its ranking information using the yacy/idx.json servlet
- peers with more than 1 GB ram will load this information from all other peers, combine that into one ranking table and store it locally. This happens during the start-up of the peer concurrently. The new generated file with the ranking information is at DATA/INDEX/<network>/QUEUES/hostIndex.blob
- this index is then computed to generate a new fresh ranking table. Peers which can calculate their own ranking table will do that every start-up to get latest feature updates until the feature is stable
- I computed new ranking tables as part of the distribition and commit it here also
- the YBR feature must be enabled manually by setting the YBR value in the ranking servlet to level 15. A default configuration for that is also in the commit but it does not affect your current installation only fresh peers
- a recursive block rank refinement is implemented but disabled at this point. it needs more testing
Please play around with the ranking settings and see if this helped to make search results better.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7729 6c8d7289-2bf4-0310-a012-ef5d649a1542
This servlet currently only serves for indexes to the web structure hosts. It can be tested by calling
http://localhost:8090/yacy/idx.json?object=host
This yacy protocol servlet is the first one that returns JSON code and that also shows index entries in a readable format. This will make the development of API applications much easier. This is also an example implementation for possible json versions of the other existing YaCy protocol interfaces.
The main purpose of this new feature is to provide a distributed block rank collection feature. Creating a block rank is very difficult if the forward-link data is first collected and then one peer must create a backward-link index. This interface provides already a partial backward index and therefore a collection of all these indexes needs only to be joined which is very easy. The result should be the computation of new block rank tables that all peers can perform.
To reduce load from peers this servlet buffers all data and refreshes it only once in 12 hours. This very slow update cycle is needed because the interface will be called round-robin from all peers once after start-up.

- added transport of string-search pattern to remote search protocol
- fixed a problem parsing snippets with a '-' inside

- added option to crawler to send error-URLs to solr
- changed solr scheme slightly (no multi-value fields where no multi values are)

- general improvements on importers, especially on auto tagging
- added get_tags (needed for tag clouds etc.)
- improved flexigrid support
- added YMarks.html (not fully working) that will eventually replace Bookmarks.html

- on client-side: fix bad IP reports from remote Peers by replacing their reported IP with their server IP if the reported IP is bad, broken or disallowed
- on server-side: the same during a peer ping (here the ping'ed server acts also as client during the back-ping) and also when receiving a message or a search where the client sends also its seed. Here the IP is replaced by the client IP if the reported IP is broken or bad
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7687 6c8d7289-2bf4-0310-a012-ef5d649a1542
This is also a protection against the foced-fake of a external IP: if such an IP was faked, then the next ping from the affected peer to another peer looks like a staticIP report. Such a bad staticIP-by-faked-response can now be discovered and fixed by the peer that gets the second ping after the first ping contained a faked response.

- added more properties to solr index
- refactoring
- more constants in switchboard
- fix for some NPEs
- recognition of more images
- removed synchronization in HandleMap (obviously not necessary?)
- added a nolocal configuration to remove excessive dns lookup (works only on allip - default off). Indexes produced with this setting are all flagged with 'local' and are (on purpose) not usable for freeworld because they will be rejected as beeing local.

- added deletion of solr index in IndexControlRWIs
- added asynchronous adding of large url lists (happens when crawls are startet with file)
- fixed npe in Image display
- replaced language warning with fine logging
- added a domain name cache in Domains that helps to speed up the isLocal property (less DNS lookups)
- added a new storage class for this new cache: KeyList. The domain key list is stored in DATA/WORK/globalhosts.list
- added concurrent solr updates and chunked transfers (50 documents until a commit is done) for high-speed feeding (> 40000 ppm)
- fixed a bug in content scraper that chopped off large parts of crawl lists (using crawl start from file)

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.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7657 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.

(directly or indirectly) and it grants a crawl-delay of 0. Then all forced pause mechanisms in YaCy are switched off and the domain is crawled at full speed.
crawl delay values can be assigned to either
- all yacy peers using the user-agent yacybot
- a specific peer with peer name <peer-name>.yacy or
- a specific peer with peer hash <peer-hash>.yacyh

- added parser for in-text appearing geo-locations
- added geo-locations to rss search result

The class still contains a potential ConcurrentModificationException which occurs when the List which contains the elements of the table of content is moified during a recursion of tagReplace(). Will try to fix this later today.

- removed configuration button for 'search only for admin' from index.html and added this to ConfigPortal
- added configuration of link verification options (iffresh, cacheonly, nocache, ifexist) to ConfigPortal
- added configuration of navigation options to ConfigPortal
- added an option to switch off automatic index cleaning in case that a link verification method fails

- 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

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

This has two aspects: the user who searches may want to increase these values to get more results and more load on the remote side and the user of the server which is accessed for this search may want to restrict the load. Both sides can now be configured. The server-site maximum load parameters are defined by a network definition and the client-side search request load can be defined by each user individually but when the remote search is done the requested service is limited to the network definition.
You can find now in the network definition file:
network.unit.remotesearch.maxcount and network.unit.remotesearch.maxtime
and in the yacy.conf file:
remotesearch.maxcount and remotesearch.maxtime
There is currently no web interface to define the client-side remote search attributes, please set them manually

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)

- 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)

- if YaCy is started with the option -gui, it is not in headless mode. Then the java 1.6 browse method is used if all other methods fail
- in linux, the path /etc/alternatives/www-browser is used if no firefox is installed

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

- the own seed file gets the lead for storage of the peer name
- exchanged default peer name generation method with one that does not use the local ip
- default peer names are now strings starting with '_anon'
- added another switch to suppress forwarding to ConfigBasic if the name was already changed
- replaced all usages of the yacy.conf peerName with access to the local seed
- changes to the peer name are now applied directly and not after the next peer ping

- this recording is then used to redirect from the Status.html page to BasicConfig in case that servlet was never submitted
- this acts as an addition to the new default pop-up page 'index.html' which offers an administration link to Status.html. For a first-time user this then redirects directly to the former start page BasicConfig.html
