from the ConfigNetwork online interface
- to make this possible, a large refactoring and reorganisation of data structures was necessary
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4803 6c8d7289-2bf4-0310-a012-ef5d649a1542
This change is inspired by the need to see a network connected to the index it creates in a indexing team.
It is not possible to divide the network and the index. Therefore all control files for the network was moved to the network within the INDEX/<network-name> subfolder.
The remaining YACYDB is superfluous and can be deleted.
The yacyDB and yacyNews data structures are now part of plasmaWordIndex. Therefore all methods, using static access to yacySeedDB had to be rewritten. A special problem had been all the port forwarding methods which had been tightly mixed with seed construction. It was not possible to move the port forwarding functions to the place, meaning and usage of plasmaWordIndex. Therefore the port forwarding had been deleted (I guess nobody used it and it can be simulated by methods outside of YaCy).
The mySeed.txt is automatically moved to the current network position. A new effect causes that every network will create a different local seed file, which is ok, since the seed identifies the peer only against the network (it is the purpose of the seed hash to give a peer a location within the DHT).
No other functional change has been made. The next steps to enable network switcing are:
- shift of crawler tables from PLASMADB into the network (crawls are also network-specific)
- possibly shift of plasmaWordIndex code into yacy package (index management is network-specific)
- servlet to switch networks

- remote crawl receipts are now transmitted concurrently in separate threads (makes remove crawls much faster!)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4605 6c8d7289-2bf4-0310-a012-ef5d649a1542
- replaced some synchronized classes by classes from util.concurrent
- used a util.concurrent.SynchronousQueue to implement a persistent sorting thread in
the very basic kelondroRowCollection which supports sorting with a second thread
in case that a double-core processing CPU is used
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4517 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4232 6c8d7289-2bf4-0310-a012-ef5d649a1542
- final flush only when tabletype = RAM
- prestacker (dns prefetch) only if tabletype = RAM and busytime <= 100
- number of maximun entries in stacker is configurable in yacy.init (stacker.slots)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4186 6c8d7289-2bf4-0310-a012-ef5d649a1542
two main changes must be implemented to enable mass remote crawls:
- shift control of robots.txt to crawl queue (away from stacker). This is necessary since remote
crawls can contain unchecked urls. Each peer must check the robots to prevent that it is misused
as crawl agent for unwanted file retrieval
- implement new index files that control double-check of remotely crawled urls
After removal of robots.txt checking from stacker threads, the multi-threading of this process is void.
Multithreading has been removed. Also the thread pools for the crawl threads had been removed, since
creation of these threads is not resource-consuming, for a detailed explanation see svn 4106

- put(key, value) methods are now used if a value added to the map should be kept as it is. Numbers are transformed (but not formatted) to an equivalent String representation.
- putASIS(...) have been removed, now done with simple put(...) (see above).
- puNum(...) can be used for number values which should be stored in a formatted way, either depending on the current locale setting for yacy (default) or in a "none" locale (see javadocs and setLocalize()).
- putHTML(...) escapes special characters into corresponding HTML enities ('<' => '<') which was done with put(...) before and so was called too often, becauses it is necessary only for very few cases. Additionally there is a "forXML" mode which only replaces < > & ".
In short: Use put(...) for almost everything, use putXY(...) if you need some special transformation of the value.
A few bugs have been fixed as well, and there should be a small performance improvement for complex pages with a lot of values.
* added additional Sum/Avg rows to access tracker pages, see http://forum.yacy-websuche.de/viewtopic.php?f=5&t=456
* removed duplicate code (mostly related to the big changes above).
TODO:
- make sure, number formats work as expected _everywhere_, report overseen stuff http://forum.yacy-websuche.de/viewtopic.php?f=5&t=437
- probably a good idea to add special putDate() methods as they are used in many pages and create duplicated formatting code + maybe some centralized handling for memory value formatting.
- further improve the speed of page creation for the WatchCrawler.

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.

and replaced old fist hash computation by new method that tries to find a gap in the current dht
to do this, it is necessary that the network bootstraping is done before the own hash is computed
this made further redesigns in peer initialization order necessary
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4117 6c8d7289-2bf4-0310-a012-ef5d649a1542
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.

- added new system update configuration page
- moved system update from status page to system udate page
- moved shutdown and restart from status page to main menu
- added new configuration properties to yacy.init (not yet actively used)
- added some methods to handle new automatic update process

after downloading a release using the download button on the status page
the user can choose any of the downloaded versions for a update.
this enables also a downgrade to a older version.
when the update button is pushed, yacy terminates, installes the choosen version
and restarts

automatically aquire release information from download archives
web pages from latest.yacy-forum.net and yacy.net are retrieved, parsed,
links wihin are analysed, sorted and the most recent developer and main
releases are provided as direct download link on the status page, if it was
discovered that a more recent version than the current version is available.
This process is done only once during run-time of a peer, to protect our
download archives from DoS by YaCy peers.

- removed restart-button on non-Windows platforms (until start-script is adjusted)
- margin for <dt>s with more than one line

- 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!
