- introduced blocking queues in CrawlStacker to make it ready for concurrency
- added a second busy thread for the CrawlStacker
The CrawlStacker is multithreaded. It shall be transformed into a BlockingThread in another step.
The concurrency of the stacker will hopefully solve some problems with cases where DNS blocks.

- removed never-used secondary crawl depth
- added a must-not-match filter that can be used to exclude urls from a crawl
- added stub for crawl tags which will be used to identify search results that had been produced from specific crawls
please update the yacybar: replace property name 'crawlFilter' with 'mustmatch'.
Additionally, a new parameter named 'mustnotmatch' can be used, which should be by default the empty sring (match-never)

- 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)

- moved constants from plasmaSwitchboard to own class (all 232 ;)
- moved remoteProxy-Methods to httpRemoteProxyConfig, better names
- removed some unnecessary code (else-statements)
* formatting (correct indentation)
* minor bugfixes (due to findbugs.sf.net)
* hopefully fixed "missing quote" (announcing StringParts as UTF-8)

from the ConfigNetwork online interface
- to make this possible, a large refactoring and reorganisation of data structures was necessary

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

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

two main changes must be implemented to enable mass remote crawls:
- shift control of robots.txt to crawl queue (away from stacker). This is necessary since remote
crawls can contain unchecked urls. Each peer must check the robots to prevent that it is misused
as crawl agent for unwanted file retrieval
- implement new index files that control double-check of remotely crawled urls
After removal of robots.txt checking from stacker threads, the multi-threading of this process is void.
Multithreading has been removed. Also the thread pools for the crawl threads had been removed, since
creation of these threads is not resource-consuming, for a detailed explanation see svn 4106

- put(key, value) methods are now used if a value added to the map should be kept as it is. Numbers are transformed (but not formatted) to an equivalent String representation.
- putASIS(...) have been removed, now done with simple put(...) (see above).
- puNum(...) can be used for number values which should be stored in a formatted way, either depending on the current locale setting for yacy (default) or in a "none" locale (see javadocs and setLocalize()).
- putHTML(...) escapes special characters into corresponding HTML enities ('<' => '<') which was done with put(...) before and so was called too often, becauses it is necessary only for very few cases. Additionally there is a "forXML" mode which only replaces < > & ".
In short: Use put(...) for almost everything, use putXY(...) if you need some special transformation of the value.
A few bugs have been fixed as well, and there should be a small performance improvement for complex pages with a lot of values.
* added additional Sum/Avg rows to access tracker pages, see http://forum.yacy-websuche.de/viewtopic.php?f=5&t=456
* removed duplicate code (mostly related to the big changes above).
TODO:
- make sure, number formats work as expected _everywhere_, report overseen stuff http://forum.yacy-websuche.de/viewtopic.php?f=5&t=437
- probably a good idea to add special putDate() methods as they are used in many pages and create duplicated formatting code + maybe some centralized handling for memory value formatting.
- further improve the speed of page creation for the WatchCrawler.

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
this made further redesigns in peer initialization order necessary

- 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.

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.

- for each crawl start, there is now a flag for text and media
- the localCrawl flag is superfluous
- added new crawl profiles
- if an image search is done, only media links are crawled for the snippets

- added an assortment importer. the old database structures can
be imported with
java -classpath classes yacy -migrateassortments
- modified wordmigration. The indexes from WORDS are now imported
to the collection database. The call is
java -classpath classes yacy -migratewords

This shall be seen as an experiment to exclude all cases where
there could be a DNS lookup during URL comparisment.
