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

- the methods {parsing, semantic analysis (condensing), structure analysis (web structure)} in the serialized indexing path had been made concurrent.
- four BlockingQueues handle concurrency and hand-over of the indexing objects, the last object in the queue is stored into a blockingQueue of maximum size 1 to serialize the process for storage (which uses IO and therefore here should not be deserialized)
- a concurrency of (CPUs + 1) is default. Single-CPU users will profil from the change because large files cannot block the indexing process any more.
- removed the secondary indexing thread, which is superfluous now. Concurrency is default for all users.

- 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 settings that are in Basic Settings
- joined pages that belong together
- moved include pages from yacy/ to /

A new port forwarding method for upnp was added.
If this method is enabled, yacy automatically determines an UPnP
capable internet gateway and configures the gateway port forwarding
settings properly.

the kelondro database needs specific information about the order of
base64-encoded keys. Since no other package depends on base64
(only the httpd uses base64 for encryption, but does not need to encode these strings)
it is good to move base64 encoding to the new ordering classes in kelondro.

- dbImporter threads are now shutdown by the switchboard on server shutdown
- adding possibility to pause a importer thread via GUI
- Bugfix for abort function
See: http://www.yacy-forum.de/viewtopic.php?p=13363#13363
*) Modification of content parser configuration
- now it's possible to configure which parsers should be enabled for the proxy,
crawler, icap, etc. separately
-
*) htmlFilterContentScraper.java
- adding regular expression to normalize URLs containing /../ and /./ parts
*) httpc.java
- adding functionality to unzip gzipped content
- requested by roland: should be used later to allow gzipped seed lists

See: http://www.yacy-forum.de/viewtopic.php?p=11804#11804
*) Adding first version of db test for mysql
NOTES:
- db user + db + db table must be created before starting the test
- db table must be empty. Entries can not be updated at the moment
- db connection properties must be changed in the sourcecode at the moment
TODOs:
- accepting connection properties via command line
- implementing update + remove + read operations
- 'maybe' adding code to create db + table if it doesn't exists
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@991 6c8d7289-2bf4-0310-a012-ef5d649a1542
- remote proxy configuration can now be "really" changed on the fly and takes effect immediately
- adding possibility to disable remote proxy usage for yacy->yacy communication
- adding possibility to disable remote proxy usage for ssl
- restructuring proxy configuration so that it is stored in a single place now
*) Adding possibility to import a foreign word DB (or even more of them in parallel)
at runtime into the peers DB
- this can be done by calling IndexImport_p.html
- ATTENTION: please not that at the moment this thread must be aborted via gui
before a normal server shutdown is done.
- TODO: integrating IndexImport Thread into normal server shutdown
- TODO: Adding posibility to import crawl-queues, etc. from foreign peers
- TODO: removing old import function from yacy.java and calling the new routines instead

various checks like the blacklist check or the robots.txt disallow check are now
done by a separate thread to unburden the indexer thread(s)
TODO: maybe we have to introduce a threadpool here if it turn out that this single
thread is a bottleneck because of the time consuming robots.txt downloads
*) improved index transfer
The index selection and transmission is done in parallel now to improve index
transfer performance.
TODO: maybe we could speed up performance by unsing multiple transmission threads in
parallel instead of only a single one.
*) gzip encoded post requests
it is now configureable if a gzip encoded post request should be send on
intex transfer/distribution
*) storage Peer (very experimentell and not optimized yet)
Now it's possible to send the result of the yacy indexer thread to a remote peer
istead of storing the indexed words locally.
This could be done by setting the property "storagePeerHash" in the yacy config file
- Please note that if the index transfer fails, the index ist stored locally.
- TODO: currently this index transfer is done by the indexer thread.
To seedup the indexer
a) this transmission should be done in parallel and
b) multiple chunks should be bundled and transfered together
*) general performance improvements
- better memory cleanup after http request processing has finished
- replacing some string concatenations with stringBuffers
- replacing BufferedInputStreams with serverByteBuffer
- replacing vectors with arraylists wherever possible
- replacing hashtables with hashmaps wherever possible
This was done because function calls to verctor or hashtable functions
take 3 time longer than calls to functions of arraylists or hashmaps.
TODO: we should take a look on the class serverObject which is inherited from hashmap
Do we realy need a synchronization for this class?
TODO: replace arraylists with linkedLists if random access to the list elements is not needed
*) Robots Parser supports if-modified-since downloads now
If the downloaded robots.txt file is older than 7 days the robots parser tries to
download the robots.txt with the if-modified-since header to avoid unnecessary downloads
if the file was not changed. Additionally the ETag header is used to detect changes.
*) Crawler: better handling of unsupported mimeTypes + FileExtension
*) Bugfix: plasmaWordIndexEntity was not closed correctly in
- query.java
- plasmaswitchboard.java
*) function minimizeUrlDB added to yacy.java
this function tests the current urlHashDB for unused urls
ATTENTION: please don't use this function at the moment because
it causes the wordIndexDB to flush all words into the
word directory!
