- refactored all code which uses URIMetadataRow as standard for word
hash length and word hash ordering and moved that to the class 'Word',
becuase the class URIMetadataRow defined the old metadata data structure
and should be superfluous in the future
- removed unused methods from URIMetadataRow as preparation for further
removal of that class
- since specific heuristic Twitter & Blekko is not longer available or redundant with OpenSearchHeuristic,
adjusted ConfigHeuristic to use OpensearchHeuristic settings only.
For this the default OSD search target list is made available (copied) by default and the other configs are removed.
- the return of QueryGoal.getOriginalQueryString includes the queryModifier, which are held separately in a modifier object,
but in most (all) cases just the query term is expected, clarified and renamed it to QueryGoal.getQueryString which returns
just the search term (if needed a .getOrigianlQueryString could be implemented in Queryparameters, adding the modifiers)
- started to adjust internal html href references from absolute to relative (currently it is mixed).
For future development we should prefer relative href targets (less trouble with context aware servlets)
request into a separate thread and ignores the furthure result of a
request if that does not answer within the requested time-out. This is a
try to solve a problem with the peer-ping, which hangs whenever a peer
appears to be dead or blocked.
where the size() and isEmpty() method is used only for statistics, which
happens at many locations in YaCy. If these methods are used for
structual reasons (like accessing the last element in an array) then it
may fail or cause other problems. As far as visible, this is not the
case.
As the solr servlet may not be available (e.g. no public search page, old version, individual access setting) a /solr/select error is
remembered in the seed.dna of the remote peer.
This is not permanent, as flag is not stored and the seed is reloaded on several occasions, it is just a memory of the recent past status.
Might also be set to "not available" on time-out of last try.
as BASIC were pwd is transmitted near clear text (B64enc).
This has some implication as RFC 2617 requires and recommends a password hash MD5(user:realm:pwd) for DIGEST.
!!! before activating DIGEST you have to reassign all passwords !!! to allow new calculation of the hash
- default authentication is still BASIC
- configuration at this time only manually in (DATA/settings) or defaults/web.xml (<auth-method>
- the realmname is in defaults/yacy.init adminRealm=YaCy-AdminUI
- fyi: the realmname is shown on login screen
- changing the realm name invalidates all passwords - but for security you are encouraged to do so (as localhostadmin)
- implemented to support both, old hashes for BASIC and new hashes for BASIC and DIGEST
- to differentiate old / new hash the in Jetty used hash-prefix "MD5:" is used for new pwd-hashes ( "MD5:hash" )
- all non-dht targets (previously separated into 'robinson' for dht-like
queries and 'node' for solr queries) are non 'extra' peers, which are
queries using solr
- these extra-peers are now selected using a ranking on last-seen,
peer-tag-matches, node-peer flags, peer age, and link count. The ranking
is done using a weight and a random factor.
- the number of extra peers is 50% of the dht peers
- the dht peers now exclude too young peers to prevent bad results
during strong growth of the network
- the number of dht peers (and therefore extra-peers) is reduced when
the memory of the peer is low and/or some documents still appear in the
indexing-queue. This shall prevent a peer from deadlocks when p2p
queries are made in a fast sequence on weak hardware.

- taking out customized SecurityHandler code as the original/default seems to just work fine
- with this individual sec. constraints can be applied via web.xml (using legacy role names)
- this allows additional features, like servlet configuration via web.xml and many more things.
- currently the standard servlets are still configured in the code (so the supplied defaults/web.xml is not realy needed, yet),
but could be expanded
- lookup for web.xml - 1. in /DATA/SETTINGS then in /defaults
