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
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
adjusted to smaller and 1-core devices.
- the workflow processor now starts no process at all. these are started
as soon as parser/condenser/indexing queues are filled.
- better abstraction
not equal. It might happen that these data is different because one of
that caches is cleaned after a while or when it is too big. The metadata
is then not cleaned, but now wiped after a checkup process at every
application start. This should cause a bit less memory usage.
during receiving of DHT submissions and when answering remote search
requests. Both events together may have caused IO-deadlocking and this
commit shall fix that.
- added a memory limitation in the zip parser and the pdf parser
- added a search throttling: if there are too many search queries are still to be computed, then new requests are not accepted for some time. if after a one second still no space is there to perform another search, the search terminates with no results. this case should only happen in case of DoS-like situations and in case of strong load on a peer like if it is integrated in metager.
- added a search cache deletion process that removes search requests in case that throttling happens

- added more instances of formatter objects to different classes to make them independent in case of lockings that may applay during synchronization of the date formatter object (date formatting is not thread-safe and must be synchronized therefore)

- cleaned up (removed special code and documentation for 27c3)
- added remote search functions to be used within cora

- introduced byte[] - based ARC method for MapHeap which avoids a String generation each time the cache is accessed
- bugfixing in required class ComparableARC

- permanent storage of auto-dom statistics in profile
- storage of profiles in WorkTable data structure

- move the header framework classes to cora
- move the ARC caching classes to cora
- refactoring of code to call these classes from cora

- fix for initial generation of crawl profiles (one more reason to remove your crawl profiles)
- more String -> byte[] migration
- more logging for cache store/hit

- removed usage of URL-Caches which could have been a memory leak
- removed unused classes and methods
- removed not necessary synchronizations
- added synchronization hacks where possible
- fine-tuned crawling speed to prevent IO of balancer
- fixed a bug in IODispatcher that may have caused that no merges were done
- reduced number of parameters in very often called methods (compare methods)
- reduced complexity of data structures of now massively used HandleSet class
- reduction of new String() and getBytes() usage / new methods to support this transition

- added BEncodedHeap class that encodes B data structures and stores that to a heap
- refactoring of MapView, this is now named MapHeap to fit into the naming scheme of the BEncodedHeap
