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

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

613ab6a69d added BEncodedHeapBag and BEncodedHeapShard which are storage container
for a new metadata store. An abstraction of the content for this storage
is defined with MapStore. A MapStore is an abstraction of a RDF Node
store.

05f34a3fa7 added a full, complete, database insert, update and delete API for the tables.
Please see this example:

list all database tables:
http://localhost:8090/api/table_p.xml

now create a new table and insert some values into 'mytable'
http://localhost:8090/api/table_p.xml?table=mytable&pk=&commitrow=&col_termin=Release%20Machen&col_datum=24.11.2011&col_status=ongoing

list the table content:
http://localhost:8090/api/table_p.xml?table=mytable&pk=

update the table and change a single value inside. You must refer to the row using a primary key 'pk'
http://localhost:8090/api/table_p.xml?table=mytable&pk=000000000001&commitrow=&col_datum=29.11.2011

you can also select rows using a search operator
http://localhost:8090/api/table_p.xml?table=mytable&pk=&count=10&search=

now lets delete the row:
http://localhost:8090/api/table_p.xml?table=mytable&pk=&deleterows=pk_000000000001

and we can also delete the complete table:
http://localhost:8090/api/table_p.xml?table=mytable&deletetable=

You can use this to administrate the robots, bookmarks and API steering using an outside application!

4bea3f9714 hack to reduce resource contention caused by massive UTF8 decodings which use java.nio resources:
used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

cb1f49d0f2 replaced all 'new String' with default encoding (missing) or UTF-8 encoding with a String generation method that uses a pre-defined Charset constant for UTF-8. This avoids a cache-lookup for the Charset object using String hashing of the String 'UTF-8'.

42414a6ae3 added two more tables in rss reader interface:
- fresh recorded rss feeds (not yet loaded or in scheduler)
- rss feeds in scheduler
The first list has a button that can be used to place rss feeds into the scheduler
The second list has a button to delete rss feeds from the scheduler

cf07b34c2d implemented the Map interface in the ARC classes so it will be possible to instantiate ARCs as
Map<byte[], Map<String, byte[]>>
Because such Maps with byte[] keys cannot be stored in hash maps (bad hashing on byte[])
another ARC with comparable Maps has been added

This will make it possible to move the HTCache class 'Cache' into the cora package because that
class may be used either with RAM caches (ARCs) or with file-based caches (BEncodedHeaps)

c60d0282fd more abstraction for tables stored in heaps:
the BEncodedHeap now implements Map<byte[], Map<String, byte[]>>
This will make it possible that also different database storage types may be added that implement also the same Map<byte[], Map<String, byte[]>> interface.

189a986ebd - modified api-call interface to record api calls with references to api-call database (carries pk)
- added recording date, last execution date and next execution date for a scheduler (scheduler to be implemented next)
- extended database access methods for more data formats, especially for date insert/retrieval
- extended 'Steering' interface to show new database fields
- migrated Steering to new http client
- extended cora http client to transmit authentication and also added some convenience methods (http response code)
- simplified database back-end (not so much specialized methods for multiple properties)
- extended date formatter to produce a special format to show dates in html (&nbsp; in spaces of date format)

8ce936bcdd added an api recording function: it shall be possible to record
all operations on YaCy in a database that should make it possible
1) to re-create a setting on fresh peers
2) to transmit a setting from one peer to another
3) to re-create crawl starts after a complete deletion of the index
This functionality will also support
4) scheduled re-crawls (new implementation)
To implement this, a new database structure has been crated that stores maps into blob heaps. to encode maps the b-encoding technique was used (this is the same encoding that torrent files use)
- added a b-encoder
- enhanced the b-decoder
- added a b-encoded map heap data structure
- added a table organisation based on b-encoded heaps
- added a servlet to maintain such tables (see Tables_p.html)
- integrated the servlet into the Advanced Settings menu
- added an api recording based on the new tables
