- The indexing queue was a historic data structure that was introduced at the very beginning at the project as a part of the switchboard organisation object structure. Without the indexing queue the switchboard queue becomes also superfluous. It has been removed as well.
- Removing the switchboard queue requires that all servlets are called without a opaque generic ('<?>'). That caused that all serlets had to be modified.
- Many servlets displayed the indexing queue or the size of that queue. In the past months the indexer was so fast that mostly the indexing queue appeared empty, so there was no use of it any more. Because the queue has been removed, the display in the servlets had also to be removed.
- The surrogate work task had been a part of the indexing queue control structure. Without the indexing queue the surrogates needed its own task management. That has been integrated here.
- Because the indexing queue had a special queue entry object and properties attached to this object, the propterties had to be moved to the queue entry object which is part of the new indexing queue withing the blocking queue, the Response Object. That object has now also the new properties of the removed indexing queue entry object.

- instead of pushing urls to other peers, the urls are actively pulled
by the peer that wants to do a remote crawl
- the remote crawl push process had been removed
- a process that adds urls from remote peers had been added
- the server-side interface for providing 'limit'-urls exists since 0.55 and works with this version
- the list-interface had been removed
- servlets using the list-interface had been removed (this implementation did not properly manage double-check)
- changes in configuration file to support new pull-process
- fixed a bug in crawl balancer (status was not saved/closed properly)
- the yacy/urls-protocol was extended to support different networks/clusters
- many interface-adoptions to new stack counters

- moved all information to columns at the right side
- long texts within the column will be removed in a second step, and will re-appear
as action items below the 'Welcome' header
- new usage hints will also appear below the Welcome header
- Peer news (in full sentences) will appear in separate column
- possibly some more grafics

-> all skin files were set to use green progressbars (should be changed to colors fitting the skins appearence)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2751 6c8d7289-2bf4-0310-a012-ef5d649a1542
If you don't use the default skin, the style will be broken or at least not complete.
YaCy now has two css-files: base.css in htroot/env and the skin. In base.css the layout and black/white text-formating-rules are defined. Colors are only defined in the skin.
The skin is now very easy to read and to change. If you want to make more changes than the colors you see in the default-skin, feel free to use the full power of css, but you are warned: The code is still not ready and may change, but we try to avoid changes which affect anything in the default-style.
Translation will be broken too because the language-files contain HTML-Code which has changed.

See: http://www.yacy-forum.de/viewtopic.php?p=11804#11804
*) Adding first version of db test for mysql
NOTES:
- db user + db + db table must be created before starting the test
- db table must be empty. Entries can not be updated at the moment
- db connection properties must be changed in the sourcecode at the moment
TODOs:
- accepting connection properties via command line
- implementing update + remove + read operations
- 'maybe' adding code to create db + table if it doesn't exists
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@991 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@968 6c8d7289-2bf4-0310-a012-ef5d649a1542
- adding automatic refresh
- accepts new parameter nameLookup which can be used to deactivate
yacy-peer name lookup (because we have problems with this on large seed-dbs)
*) ViewFile
New page that can be used to view
- original content
- plain text content
- parsed content
- parsed sentences
of a webpage specified by there url hash
Mainly for debugging purpose at the moment
*) Robots.txt
Bugfix for if-modified-since usage
TODO: synchronization of downloads to avoid loading the same robots-file
multiple times in parallel by different threads
*) Shutdown
Better abortion of transferRWI and transferURL sessions on server shutdown
*) Status Page
Adding icon to start/stop crawling via status page
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@950 6c8d7289-2bf4-0310-a012-ef5d649a1542
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!
