for indexing, the plasmaWordIndex.
The new data structure is ready-to-use, but currently disabled.
It can be activated by setting the static
plasmaWordIndex.useCollectionIndex
to true. This shall be done for testing purpose.
The new index is stored to
DATA/INDEX/PUBLIC/TEXT
The directory PLASMA shall be used only for crawler in the future.
Attention: during testing the data structure in INDEX may change,
and created indexes with the new data structure may get useless.

to store the index entry. This is another step to move to the new database structure.
A side effect of this change is, that index storage uses much less RAM space,
which affects the index RAM cache.

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.

an iteration of key elements in kelondroTree databases is no longer supported.
this is now replaced by an iteration of kelondroRow.Entry objects from the database
Iteration of keys from the database was mostly followed by retrieval of the row
from the database, whcih caused unnecessary database load.
The index selection was also redesigned to use the new row iteration methods.
This affects many funktions, most important is the DHT selection routine which is now much faster.

when extracting from eurl, the html output format is recommended, since
this format adds also the fail reason to the domain/url.
The complete syntax for domain extraction is now
java -Xmx<megabytes>m -classpath classes yacy -domlist [ -source { lurl | eurl } ] [ -format { text | zip | gzip | html } ] [ <path to DATA folder> ]

* mainly for the transition to the new indexing database structure
* a bugfix for an endless loop inside kelondroTree iteration
* a bugfix for bulk read inside a kelondroTree iteration; the bug caused that some elements had been iterated twice
* very strong speed enhancement for url/domain extraction

a) renaming the parent folder in the tgz file to yacy
(can be configured via build properties file)
b) reconfiguring build file to throw an error if a file
name is too long
Please note that currently there is _no_ proplem with too long
class names because of step a.

find the same words as before. This was caused because indexContaines stored the url references
with a hashtable. A tree was needed to work with the index conjunction-by-numeration
- added permanent ram cache flush (again)
- removed direct flush of ram cache after a large container is added.
this happens especially during DHT transmission and therefore this fix should
speed up DHT transmission on server side.
- removed unused and out-dated methods
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1765 6c8d7289-2bf4-0310-a012-ef5d649a1542
The cache will fill up and flushed explicitely when it is full.
This shall remove double-access of assortments (indexing and flush)
during indexing process. Hopefully this should reduce IO.
The main idea is: the cache shall mainly be flushed by DHT transfer, and
only indexes that shall be hosted by the own peer are flushed to the
assortments. This needs further work.

- changed index collection process: indexes are not first flushed to indexEntity,
but now collected directly from ram cache and assortments

- implemented word-distance computation during search

it is now possible to select only assortments or only files in WORDS
selection of words only from the ram cache is not yet possible.

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.

(no more NULL values are returned, instead, an IOException is thrown)
- removed ugly damagedURLS implementation from plasmaCrawlLURL.java
(this inserted a static value into the Object which is not really a good style)
- re-coded damagedURLS collection in yacy.java by catching an exception and evaluating the exception message
to do:
- the urldbcleanup feature must be re-tested

* modified generation of dom-lists so that they can be also generated as html
these options can be called as:
java -classpath classes yacy -domlist -format html
java -classpath classes yacy -domlist -format html .
java -classpath classes yacy -domlist -format text .
java -classpath classes yacy -urllist -format html .
java -classpath classes yacy -urllist -format text .
the -format <type> can be ommitted. The text is default
a home path can be asserted or omitted at the end of the parameters

- 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

- avoiding unnecessary exports of index word entries to string format and reimporting it afterwards

ATTENTION: not tested very well. please use this with care and always make a db backup

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!
