- download a wikipedia dump, i.e. dewiki-20090311-pages-articles.xml.bz2
from http://download.wikimedia.org/dewiki/20090311/
- move dewiki-20090311-pages-articles.xml.bz2 to DATA/HTCACHE/
- start the conversion; open a command shell, move to the yacy home directory and execute
java -Xmx2000m -cp classes:lib/bzip2.jar de.anomic.tools.mediawikiIndex -convert DATA/HTCACHE/dewiki-20090311-pages-articles.xml.bz2 DATA/SURROGATES/in/ http://de.wikipedia.org/wiki/
this generates a series of files to DATA/SURROGATES/in
if YaCy is running (it may run concurrently), it fetches all new dumps in the surrogate-in directory. The export process is transaction-save, that means YaCy will not start reading a dump while the dump is not completely finished.

- removed historic, possibly unused code from wiki parser that was in conflict with actual wikipedia wiki code
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5790 6c8d7289-2bf4-0310-a012-ef5d649a1542
This was done to prepare the wiki parser as parser for wikipedia dumps, which will be used for performance test (to omit crawling)

* added possibility to find maximum possible heap size
you can get it via getWin32MaxHeap.bat
this may cause high system load
moreover the found limit is no guarantee for stable startups since it depends on system configuration

- applied knowledge about concurrent files stream reading and index processing from the wikimedia reader
to the EcoTable initialization process: the file reader is now concurrent to the index generation
- changed also some initialization processes to avoid some pauses during initialization

files exported from mediawiki using the xml schema according to
http://www.mediawiki.org/xml/export-0.3/
can be processed to be viewed in a YaCy servlet.
To acces such a file, place it into
DATA/HTCACHE/mediawiki/
i.e. the export from german wikipedia would be:
DATA/HTCACHE/mediawiki/wikipedia.de.xml
This file can then be accessed using the URL
http://localhost:8080/mediawiki_p.html?dump=wikipedia.de.xml&title=YaCy
if this is done the first time, an index file is created
(for this case: more than 4 million lines must be written, this takes about 15 minutes)
Then try the same url again.
- enhanced also the md5 computation speed

- metadata and results from statistical analysis are compared and result is printed out as debug lines
- added ranking profile for wanted language
- added class with ISO 639 table, a list of all valid country codes that will be used for the language identification
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5187 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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)

- added paths for new libraries in classpath for eclipse
- refactoring to remove compiler warnings (static access to finals variables)
- removed some unused import
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5055 6c8d7289-2bf4-0310-a012-ef5d649a1542
- removed unnecessary code (unused variables, String.toString)
- corrected some calculations (cast int to double or long ;)
- improved little performance (using Integer.valueOf() instead of new Integer)
- log if some File-actions fail (mkdir(), delete(), ...) and some ignored exceptions
- finalized some (more) fields
- finally close some streams
- made inner classes static if not using environment
- generalized some equals (from specificClass to Object)
- fixed some potential nullpointer accesses

- 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)

- partly redesign of diskUsage: little bit more functional behavior, less side effects, better error case handling
- the resourceObserver can now show a error message if the diskUsage is 'out of order'

the most important fix was the addition of the yacybot user-agent for robots.txt loading,
because web masters look for that access to see if the crawler behaves correctly.

1. The usage and dependency of the plasmaSwitchboad was used many times in the past but this was
a bad mistake. The classes should be independent from the switchboard to support a better abstraction. Therefore the object was removed. The parameters from the switchboard are computed outside and then handed over.
2. the class is considered as a tightly connected to hardware resources. Classes which handle data that cannot be replicated because it would need to replicate hadware should not support dynamic object allocation, but should be coded as collection of private static methods. Therefore all class objects had been transformed into static private objects.

- no access check when a search is made only local without snippet fetch
- added comment and status message in resourceObserver (this takes very long at startup time!)

pleas disable before release because 2nd update fails at the moment
and commandline handling has to be improved for windows
* update via new unTar class
please review stream- and exceptionhandling because I'm fairly new to Java
maybe it can be done concurrent
* updated windows startscripts to values from yacy.init

- added a great number of printStackTrace and new exceptions that shall be used to find the cause
for a bug in yacy client-server communication which causes the interruption of data transfer
which then causes the parser bug for the seed strings.
- tried to fix the communication bug on server-side (copy functions)
Be aware that the log may be full of errors and bugs - there should not be more bugs but there is more to see

- 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!

At the current state it allows formatting of numbers (integer + decimal types) for output according to the Locale derived from the language setting in yacy. Network.(html|xml) and Status.html have been changed to use it for now (TODO: should be integrated into other servlets as well to reduce duplicate formatting code).
NOTE: For now the output format for Network.xml simulates the old behaviour which is wrong (it uses '.' as decimal and grouping separator), to make sure external scripts like the yacystats.de one won't break with this update.

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.

to search procedure. This function can currently not used through the
search interface, but only through remote search.
added accumulation of search attributes to enable the audio, video,
image and application selection.
fixed a problem with external URL representation generation
