in extreme situations this will cause that no remote crawls are send out any more
this is bad, but it protects the case where failing remote crawls fill up the local queue too much,
which is even worse

and replaced old fist hash computation by new method that tries to find a gap in the current dht
to do this, it is necessary that the network bootstraping is done before the own hash is computed

there is no waiting until the local search terminates to show the result page.
the local search appear like all other results from remote peers using a separated thread.
This has especially a stron effect, if the local index for a specific word is large.

- removed web structure picture from indexing menu and grouped it together with htcache monitor
- added a database for terminated crawls, when a crawl is finished it is automatically moved to the new database
- extended crawl profile edit servlet, shows now also terminated crawls
- option that was used to delete profiles is now redesigned to a function that moves the current crawl to the terminated crawls and removes all urls from the current queues!
- fixed here and there problems with indexing queues
- enhances indexing speed by changing cache flush sizes.
- changed behaviour of crawl result servlet: the list of crawled urls is shown if there is one, othevise the overview window is shown
attention: the new profile databases are not compatible with the old one. current crawls will be lost! the web index is not touched.
next steps: the database of terminated crawls can be used to start with them a new crawl. This is useful if one wants to re-crawl specific pages and wants to use a old crawl profile.

1. avoid adding duplicate file name entries in config properties for lists,
2. correctly merge all path masks from all list files for the same host masks,
3. rewrite helper methods standard java methods for Collection transformations,
4. merged various methods with identical functionality for different Collection implementations into one,
5. minor refactoring to improve code readability.

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.

- 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

some urls are fetched so the url cache can be filled with these urls
- the url-prefetch is used to sort out some unresolved urls
- the snippet-fetcher is triggered with the search event id. This is used
to remove missing snippets from the search cache so they will not be displayed again

it is necessary for the new search process that will do automatic re-searches
a positive effect is, that when a re-search is done it can be monitored how many
results had been contributed from other peers. The message for this contribution
was moved from the end of the result page to the top.
* enhanced re-search time when a global search was done an the local index has
already a great number of results for this word
* re-organised presearch computation; must be further enhanced

collection objects has been reduced to 50%:
- set new memory calculation functions for indexing process
- adjusted guessed memory amount

try new recommended value (see performanceQueues) and see if OOMs occur.
-> report maximum recommended value, so we can set new default values.

target servers had been able to see search words from the referrer of the favicon fetch.
This has been removed by using the getImage - servlet for favicon fetch.
Since java does not support loading of bmp and ico-Images, such parsers had been added.
The image parser had been coded from their original microsoft documentation.
This influences also the image-search functionality: there can now be a preview
of found bmp-images. Another benefit: favicons for search results are now cached with the HTCACHE.

we will provide two different releases in the future, one standard release and one 'pro'-release.
the 'pro'-release contains all additional parsers AND has different default performance values.
The pro-version differs therefore from the previous 'all'-version by this default values.
The pro-configuration is automatically choosen if the libx-folder exists. If a version is once initialized, its configuration stays independently from an existing libx folder.
The ant targets had been changed. There are now 3 different targets to create standard and pro-releases, and one target to upgrade:
- dist: creates a standard release (only, no libx target any more)
- distPro: creates a pro-release (includes the libx)
- distExt: creates a libx-release which includes the libx-folder only. It may be used to upgrade from standard to pro
Furthermore, the naming of 'dev'-releases had been removed.

http://www.yacy-forum.de/viewtopic.php?t=3854
This is a serious problem that is caused by the database bug between 0.511 - 0.513
which produced a large number of double-entries in the RWI index. The uniq()-method
tries to fix this, and it does not terminate when the index is large and the number
of double-occurrences is also large. This patch does simply implement a time-controlled
termination, which does not heal the inconsistency problem. The uniq-method itself
is correct and does not need a bugfix, the non-termination is simply caused by the large number
of data that is shifted during the process. It was possible to reproduce this behaviour
in a test environment.
A real fix would need to:
- enhance the uniq()-method by using a recursive, binary segmentation of the array to be fixed
- uniq() must report the entries that are double
- the double-entries must be deleted from the collection index (from the index and the collections) to heal the problem

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.

this shall be used to store a fragment of the index on another physical device,
to split IO load and enhance access speed. The index is splitted in such a way
that the LURLs are stored to the secondary location, and the RWIs to the primary
location. This is especially useful for environments where symbolic links are
not possible and may cause IO access even if there is no write access to the
device which hosts the symbolic link.

- the general NURL-index for all crawl stack types was splitted into separate indexes for these stacks
- the new NURL-index is managed by the crawl balancer
- the crawl balancer does not need an internal index any more, it is replaced by the NURL-index
- the NURL.Entry was generalized and is now a new class plasmaCrawlEntry
- the new class plasmaCrawlEntry replaces also the preNURL.Entry class, and will also replace the switchboardEntry class in the future
- the new class plasmaCrawlEntry is more accurate for date entries (holds milliseconds) and can contain larger 'name' entries (anchor tag names)
- the EURL object was replaced by a new ZURL object, which is a container for the plasmaCrawlEntry and some tracking information
- the EURL index is now filled with ZURL objects
- a new index delegatedURL holds ZURL objects about plasmaCrawlEntry obects to track which url is handed over to other peers
- redesigned handling of plasmaCrawlEntry - handover, because there is no need any more to convert one entry object into another
- found and fixed numerous bugs in the context of crawl state handling
- fixed a serious bug in kelondroCache which caused that entries could not be removed
- fixed some bugs in online interface and adopted monitor output to new entry objects
- adopted yacy protocol to handle new delegatedURL entries
all old crawl queues will disappear after this update!
