94f21d9403 activated new kelondroEcoTable file structure.
This data structure replaces almost all files in the PLASMA directory
also the collection.index and the LURL-db will be created as Eco-DB, if it does not exist before
existing Flex-databases will be used as they are (the is no data lost)
If you want to force the creation of a Eco-collection.index, simply delete the old index.
The Eco file system will only be used if there is enough memory.
The collection.index RAM limit is 200MB, if you have less, a flex-Table is createt.

dc26d6262b - removed write buffer from kelondroCache (was never used because buggy; will now be replaced by new EcoBuffer)
- added new data structure 'eco' for an index file that should use only 50% of write-IO compared to kelondroFlex
The new eco index is not used yet, but already successfully tested with the collectionIndex
The main purpose is to replace the kelondroFlex at every point when enough RAM is available.
Othervise, the kelondroFlex stays as option in case of low memory (which then can even use a file-index)

4dc438f7e7 moved to Java 1.5:
- changed build script to use java 1.5 compiler
- first stept to resolve missing generics definition (about 400 from over 4100 'missing'-warnings)
- added key-iterator to kelondro databases (for rapid from-memory enumerations, will be used for domain name collection, not used yet)

please set your development environment to use java 1.5!

1488769e1f cleanup of unmaintained and outdated performance methods:
removed object pools in httpc. Object pooling is not recommended,
if the creation of the object is not time-intensive. Object pools are only useful,
if there is much computation necessary to create some basic data that is stored
in the object pool and can be re-used. This does not apply to object pools in YaCy.
Object pooling of client sessions would make sense if they would allow re-use of
living connections to other yacy clients. But every connection is closed after usage
of an object in the client pool, therefore the YaCy server client objects are not such
that hold hardware/network-allocated entities.

daf0f74361 joined anomic.net.URL, plasmaURL and url hash computation:
search profiling showed, that a major amount of time is wasted by computing url hashes. The computation does an intranet-check, which needs a DNS lookup. This caused that each urlhash computation needed 100-200 milliseconds, which caused remote searches to delay at least 1 second more that necessary. The solution to this problem is to attach a URL hash to the URL data structure, because that means that the url hash value can be filled after retrieval of the URL from the database. The redesign of the url/urlhash management caused a major redesign of many parts of the software. Since some parts had been decided to be given up they had been removed during this change to avoid unnecessary maintenance of unused code.

4779f314fe first version of next-generation search interface:
- snippets are not fetched by browser using ajax, they are now fetched internally
- YaCy-internat threads control existence of snippets and sort out bad results
- search results are prepared using SSI includes
- the search result page is visible right after the search request, the results drop in when they are detected
- no more time-out strategy during search processes, results are shifted within queues when they arrive from remote peers
- added result page switching! after the first 10 results, the next page can be retrieved
- number of remote results is updated online on the result page as they drop in
- removed old snippet servelet (which had been also a security leak btw)
- media search is broken now, will be redesigned and fixed in another step

ba2c307ab3 optimized memory allocation in kelondroRow.Entry
such an entry cannot be instantiated without allocation of new byte[]; instead
it can re-use memory from other kelondroRow.Entry objects.
during bugfixing also other bugs may have been solved, maybe the INCONSISTENCY problem
could have been solved. One cause can be missing synchronization during bulk storage
when a R/W-path optimization is done. To test this case, the optimization is currently
switched off.
More memory enhancements can be done after this initial change to the allocation scheme.

30888e7a2f implementation of search constraints
Such constraints may formulate specific restrictions to web searches
This is implemented by scraping information for constraints from a web
page during parsing, and storing flags to the pages within the web index.

In this first step, only information for index pages ("index of", directory listings)
are scraped and stored in flags
- added new flag class kelondroBitfield
- added scraper method in condenser
- added bitfield structure for all scrape types (see also condenser)
- added bitfield structure for appearance locations (see RWIEntry)
- added handover protocol for remote search and index distribution
- extended kelondroColumn class to hold bitfield types
- added another search attribute on search page (index.html)
- extended search-filter to enable filtering of non-matching constraints
- set all new database types to be default
- refactoring: moved word hash generation to condenser class
