5e31bad711 - the webgraph shall store all links which appear on a web page and not
all unique links! This made it necessary, that a large portion of the
parser and link processing classes must be adopted to carry a different
type of link collection which carry a property attribute which are
attached to web anchors.
- introduction of a new URL class, AnchorURL
- the other url classes, DigestURI and MultiProtocolURI had been renamed
and refactored to fit into a new document package schema, document.id
- cleanup of net.yacy.cora.document package and refactoring

765943a4b7 Redesign of crawler identification and robots steering. A non-p2p user
in intranets and the internet can now choose to appear as Googlebot.
This is an essential necessity to be able to compete in the field of
commercial search appliances, since most web pages are these days
optimized only for Google and no other search platform any more. All
commercial search engine providers have a built-in fake-Google User
Agent to be able to get the same search index as Google can do. Without
the resistance against obeying to robots.txt in this case, no
competition is possible any more. YaCy will always obey the robots.txt
when it is used for crawling the web in a peer-to-peer network, but to
establish a Search Appliance (like a Google Search Appliance, GSA) it is
necessary to be able to behave exactly like a Google crawler.
With this change, you will be able to switch the user agent when portal
or intranet mode is selected on per-crawl-start basis. Every crawl start
can have a different user agent.

5878c1d599 - refactoring of log to ConcurrentLog:
jdk-based logger tend to block
at java.util.logging.Logger.log(Logger.java:476) in concurrent
environments. This makes logging a main performance issue. To overcome
this problem, this is a add-on to jdk logging to put log entries on a
concurrent message queue and log the messages one by one using a
separate process.
- FTPClient uses the concurrent logging instead of the log4j logger

5f0ab25382 removed the option to prevent removal of & parts inside of the
MultiProtocolURI during normalform computation because that should
always be done and also be done during initialization of the
MultiProtocolURI Object. The new normalform method takes only one
argument which should be 'true' unless you know exactly what you are
doing.

0f63de8236 - it is now possible to start several OAI imports concurrently
(still not possible to start them with one single request, that will be next)
- added a monitor for all running and finished OAI imports (with a little bit of animation..)

350d13e153 very first working version of oai-pmh importer: if given the right url, the importer can read and index listRecord xml files and calculate the right resumptionURL which is then given as next default start point for the importer url input.
no automatic harvesting by now, this will be done later

a0e891c63d - some redesign in UI menu structure to make room for new 'Content Integration' main menu containing import servlets for Wikimedia Dumps, phpbb3 forum imports and OAI-PMH imports
- extended the OAI-PMH test applet and integrated it into the menu. Does still not import OAI-PMH records, but shows that it is able to read and parse this data
- some redesign in ZURL storage: refactoring of access methods, better concurrency, less synchronization
- added a limitation to the LURL metadata database table cache to 20 million entries: this cache was until now not limited and only limited by the available RAM which may have caused a memory-leak-like behavior.
