- some hacks for less memory usage:
-- less usage of buffer and cache memory in EcoFS
-- buffer allocation on-demand in BufferedIOChunks
-- removed largest ybr idx

- after a index selection is made, the index is splitted into its vertical components
- from differrent index selctions the splitted components can be accumulated before they are placed into the transmission queue
- each splitted chunk gets its own transmission thread
- multiple transmission threads are started concurrently
- the process can be monitored with the blocking queue servlet
To implement that, a new package de.anomic.yacy.dht was created. Some old files have been removed.
The new index distribution model using a vertical DHT was implemented. An abstraction of this model
is implemented in the new dht package as interface. The freeworld network has now a configuration
of two vertial partitions; sixteen partitions are planned and will be configured if the process is bug-free.
This modification has three main targets:
- enhance the DHT transmission speed
- with a vertical DHT, a search will speed up. With two partitions, two times. With sixteen, sixteen times.
- the vertical DHT will apply a semi-dht for URLs, and peers will receive a fraction of the overall URLs they received before.
with two partitions, the fractions will be halve. With sixteen partitions, a 1/16 of the previous number of URLs.
BE CAREFULL, THIS IS A MAJOR CODE CHANGE, POSSIBLY FULL OF BUGS AND HARMFUL THINGS.

The feature will provide two basic entities:
- you can integrate image links which point to your yacy installation anywhere in the web.
the image can be loaded with
<img src="http://<yourpeer>:<yourport>/cytag.png?icon=invisible&nick=<yournickname_or_community_id>&tag=<anything>">
This will place a invisible 1-pixel image. If you change the icon=invisible to icon=redpill, you will see a red pill
Use this, to track your activity in the web.
- you can view your tracks at
http://localhost:8080/Tracks.html
- There is a public api to your tracks at
http://localhost:8080/api/tracks_p.json
which needs authentication

in the network configuration, you can configure a whiteliste and a blacklist
- blacklistet clients cannot search
- whitelistet client get never any search restrictions
- for all other clients: apply DoS search restrictions
Please see the example configuriation in yacy.network.freeworld.unit
by default, all clients from localhosts get whitlistet.
If you have your own YaCy network, please put all the IPs of your peers into the whitelist

- added dummy servlet class, because otherwise the template engine is not triggered.
thats so because the yacy httpd works much faster as normal file server without a scan
of the served pages. Therefore each page with templates must now have a class file associated to it.
- fixed json output format of yacysearch

The cache is now flushed only for one second every ten seconds. During a crawl the cache
fills up completely, and is only flushed if space is needed for more documents.

- introduced blocking queues in CrawlStacker to make it ready for concurrency
- added a second busy thread for the CrawlStacker
The CrawlStacker is multithreaded. It shall be transformed into a BlockingThread in another step.
The concurrency of the stacker will hopefully solve some problems with cases where DNS blocks.

- applied knowledge about concurrent files stream reading and index processing from the wikimedia reader
to the EcoTable initialization process: the file reader is now concurrent to the index generation
- changed also some initialization processes to avoid some pauses during initialization
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5354 6c8d7289-2bf4-0310-a012-ef5d649a1542
- removed never-used secondary crawl depth
- added a must-not-match filter that can be used to exclude urls from a crawl
- added stub for crawl tags which will be used to identify search results that had been produced from specific crawls
please update the yacybar: replace property name 'crawlFilter' with 'mustmatch'.
Additionally, a new parameter named 'mustnotmatch' can be used, which should be by default the empty sring (match-never)

- implemented vertical DHT acceptance ("my own DHT") to accept new targets
- added new target computation for global search: addresses vertical targets also
- enhanced remote crawling: collection of remote crawl urls if queue has less than 100 entries (was: 0 entries)
- better performance value computations for PPM selection in network configuration
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5319 6c8d7289-2bf4-0310-a012-ef5d649a1542
- two different computations (but mathematical equivalent) of the DHT distance had been consolidated
- moved from 0.0 .. 1.0 double-range position computation to 0 .. Long.Max range for DHT targets
- added fast Long - to - hash computation
- high-precision target computation of gaps for new peers
- added new target computation for horizontal and vertical DHT targets (not yet in use)
- old horizontal-only DHT targets will be upwards compatible to new horizontal and vertical DHT positions

- entries are buffered and written as stream with many entries at once (saves many IO accesses)
- entries are compressed with gzip: increases capacity of cache
- concurrency for stream-writing and compression: all writings to the cache are non-blocking
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5284 6c8d7289-2bf4-0310-a012-ef5d649a1542
- files are not stored any more as individual files
- a new database structure using BLOBHeap files stores many cache entries in common files
- all file-writing procedures had been migrated to generate byte[] objects which are written with the new database methods
this is only an intermediate step to the final architecture, where cached files are written together with their metadata in one single database structure.

- small change to network grafics: smaller circles / more URLs necessary for full radius; more PPM necessary for full crawling circles
- fixed exclusion search ('-' did not work any more)
- fixed NPE bug when FTP loader wrote to the error-db

- removed distinction between header file types for http and ftp; ftp is simulated by using http properties
- removed all old resourceInfo classes that handled this distinction
- introduced a new distinction between http request and http response objects
- unified new response objects with two other object types that had been introduced elsewhere
- changed all servlet call methods to use the new http request header object type
- divided static object keys for http header properties into request and response types
- refactoring here and there (a large number of type changes and many methods merged/moved)

- removed unnecessary code (unused variables, String.toString)
- corrected some calculations (cast int to double or long ;)
- improved little performance (using Integer.valueOf() instead of new Integer)
- log if some File-actions fail (mkdir(), delete(), ...) and some ignored exceptions
- finalized some (more) fields
- finally close some streams
- made inner classes static if not using environment
- generalized some equals (from specificClass to Object)
- fixed some potential nullpointer accesses

- moved constants from plasmaSwitchboard to own class (all 232 ;)
- moved remoteProxy-Methods to httpRemoteProxyConfig, better names
- removed some unnecessary code (else-statements)
* formatting (correct indentation)
* minor bugfixes (due to findbugs.sf.net)
* hopefully fixed "missing quote" (announcing StringParts as UTF-8)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5031 6c8d7289-2bf4-0310-a012-ef5d649a1542
- introduced a new BLOB file format: kelondroBLOBHeap. This is a flat file with an index in RAM.
very similar to the eco-tables, but with flexible value sizes. It will replace the kelondroBLOBTree,
which is based on a kelondroTree, a file-AVL-based index data structure.
- the HTCACHE header file was replaced by the new blob heap file structure
- the robots.txt file was replaced by the new blob heap file structure
- the robots parser was enhanced (bugfixing for double-loading of the same robots.txt)
- other BLOB-dependent data structures were prepared to use also the new BLOB heap
- fixed a bug in the snippet fetch process: the file header was not written to the header index
There should now be less IO during snippet fetch and during crawling

- partly redesign of diskUsage: little bit more functional behavior, less side effects, better error case handling
- the resourceObserver can now show a error message if the diskUsage is 'out of order'
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4973 6c8d7289-2bf4-0310-a012-ef5d649a1542
- no more keep-order parameter in remove (it was not possible to make this strict, and not useful)
- some small enhancements in balancer
- robots parser without references in switchboard
- changes synchronization in robots

the most important fix was the addition of the yacybot user-agent for robots.txt loading,
because web masters look for that access to see if the crawler behaves correctly.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4968 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added option to set minimum crawl delta for domains in balancer
- added default values to crawl deltas in yacy.init
- added configuration for these deltas in performance queues
- enhanced performance setting computation (more time for indexing queue for a faster flush
- remote crawling is now enabled during local crawling if indexer has space and time for more links
- added database stub for new distributed file system
- refactoring of time computation to get an abstraction level that will be used by a TTL rule in new distributed file system
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4966 6c8d7289-2bf4-0310-a012-ef5d649a1542
1. The usage and dependency of the plasmaSwitchboad was used many times in the past but this was
a bad mistake. The classes should be independent from the switchboard to support a better abstraction. Therefore the object was removed. The parameters from the switchboard are computed outside and then handed over.
2. the class is considered as a tightly connected to hardware resources. Classes which handle data that cannot be replicated because it would need to replicate hadware should not support dynamic object allocation, but should be coded as collection of private static methods. Therefore all class objects had been transformed into static private objects.

A large refactoring was neccessary
- added another crawl start option: automatic restriction to sub-path
- removed crawlStartSimple and renamed crawl start expert
to crawl start (without expert)
- some changes to texts in crawl start
- added some more deletions when an web index is deleted:
delete also queues and robots cache

- access is granted for localhost users to administration pages by default
- the default setting can be changed in the BasicConfig.html page
- if the BasicConfig page was accessed with post and no password was submitted, a random password is generated
- a headless installation MUST give a password upon first call of the configuration page, otherwise they will not be able to access it again
- if no password is given within 10 minutes after start-up, a random password is generated

from the ConfigNetwork online interface
- to make this possible, a large refactoring and reorganisation of data structures was necessary
