The resource observer is now able to recognize free disk space AND
available space for YaCy. The amount of space which is assigned for YaCy
are defined in new settings in the configuration file.
Furthermore, there is now a cleanup process which deletes files in case
that an autodelete is activated. The autodelete is now BY DEFAULT ON if
the disk space is low, which means that YaCy starts to delete documents
when the disk is full!
admin, we expect that the user wants to check recently crawled document
to ensure that recent crawl results are inside the search results, we do
a soft commit here.
occupied disc space. These values are also shown on the status page.
The disc space calculation shall be used for a disk-limitation of the
search index.
introduced, it was also used for search facets. The generic search
facets are now deduced from generic solr fields which makes jena as tool
for facet semantics superfluous.
works fine to restrict language for local solrSearches.
More work needs to be done to make rwi/remote searches respect the modifier.language restriction.
It is now possible to assign every peer other YaCy peers as remote solr
server which are only used for read operations during search. This also
affects crawling: it will exclude urls from crawls which exist on remote
solr/remote YaCy peers.
- 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)
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" )
