This is a preparation to introduce other index tables as used now only for reverse text indexes. Next application of the reverse index is a citation index.
Moved to version 0.74

- do not display indexed html (solves xss issues)
the single words are analyzed for already marked parts. this is needed to avoid false encoding of the marker (<b>) tags.
- improved speed for existing routine
heavy used regex pattern are precompiled now

- removed the now superfluous HT storage thread
- reduced number of file decompression by shifting the compression moment to the future
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5286 6c8d7289-2bf4-0310-a012-ef5d649a1542
- files are not stored any more as individual files
- a new database structure using BLOBHeap files stores many cache entries in common files
- all file-writing procedures had been migrated to generate byte[] objects which are written with the new database methods
this is only an intermediate step to the final architecture, where cached files are written together with their metadata in one single database structure.

- the condenser does not abandon too small words any more before feeding the statistics
- for text indexing no more urls are used to feed the index (this was wrong, but in contrast the indexing of urls for media search is necessary)
- urls are not used any more to feed the statistics
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5197 6c8d7289-2bf4-0310-a012-ef5d649a1542
- removed distinction between header file types for http and ftp; ftp is simulated by using http properties
- removed all old resourceInfo classes that handled this distinction
- introduced a new distinction between http request and http response objects
- unified new response objects with two other object types that had been introduced elsewhere
- changed all servlet call methods to use the new http request header object type
- divided static object keys for http header properties into request and response types
- refactoring here and there (a large number of type changes and many methods merged/moved)

- refactoring of the HTCache (separation of cache entry)
- added new storage class for BLOBs. (not used yet, this is half-way to a new structure)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5062 6c8d7289-2bf4-0310-a012-ef5d649a1542
- removed unnecessary code (unused variables, String.toString)
- corrected some calculations (cast int to double or long ;)
- improved little performance (using Integer.valueOf() instead of new Integer)
- log if some File-actions fail (mkdir(), delete(), ...) and some ignored exceptions
- finalized some (more) fields
- finally close some streams
- made inner classes static if not using environment
- generalized some equals (from specificClass to Object)
- fixed some potential nullpointer accesses

- fixed loosing of own seed hash (hopefully)
- fixed a bug with crawl start s beginning with (bookmark) files
- added better IP recognition during hello process

from the ConfigNetwork online interface
- to make this possible, a large refactoring and reorganisation of data structures was necessary
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4803 6c8d7289-2bf4-0310-a012-ef5d649a1542
This change is inspired by the need to see a network connected to the index it creates in a indexing team.
It is not possible to divide the network and the index. Therefore all control files for the network was moved to the network within the INDEX/<network-name> subfolder.
The remaining YACYDB is superfluous and can be deleted.
The yacyDB and yacyNews data structures are now part of plasmaWordIndex. Therefore all methods, using static access to yacySeedDB had to be rewritten. A special problem had been all the port forwarding methods which had been tightly mixed with seed construction. It was not possible to move the port forwarding functions to the place, meaning and usage of plasmaWordIndex. Therefore the port forwarding had been deleted (I guess nobody used it and it can be simulated by methods outside of YaCy).
The mySeed.txt is automatically moved to the current network position. A new effect causes that every network will create a different local seed file, which is ok, since the seed identifies the peer only against the network (it is the purpose of the seed hash to give a peer a location within the DHT).
No other functional change has been made. The next steps to enable network switcing are:
- shift of crawler tables from PLASMADB into the network (crawls are also network-specific)
- possibly shift of plasmaWordIndex code into yacy package (index management is network-specific)
- servlet to switch networks

- refactoring of word/phrase handling: word abstraction from condenser becomes part of index element handling
- removed unused code parts from condenser

this is another step to enable multiple, concurrent fulltext-indexes
- another try to make the yacy-httpc more stable

- enhanced text parser (condenser): found and eliminated bad code parts; increase of speed
- added handling of image preview using the image cache from HTCACHE
- some other minor changes
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4507 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added image domain presentation to image preview
- added new search page to menu
- added automatic re-search when an old search profile is requested and a crawl is ongoing,
to fetch newly crawled entries
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4501 6c8d7289-2bf4-0310-a012-ef5d649a1542
This is performed using a 3-stage sorting process:
- sort by relevance, then do snippet-fetch
- sort snippets by relevance then do image link extraction
- sort image links by image size; unknown sizes are handled like small sizes
- only the exact amount of images as requested are shown

- no more table copy for error-eco table
- optional table copy for lurl-entries
- more abstractions (less single constant strings)
- better logging (using host names instead of ips)

- refactoring of plasmaParserDocument to use Dublin Core - compatible property names
- redesign of url handling in parser and condenser (less String-to-yacyURL conversion)
- more generics
