This is a preparation to introduce other index tables as used now only for reverse text indexes. Next application of the reverse index is a citation index.
Moved to version 0.74

This is the start of a testing phase for IndexCell data structure which will replace
the collections and caching strategy. IndexCall creation and maintenance is fast, has
no caching overhead, very low IO load and is the basis for the next data structure,
index segments.
IndexCell files are stored at DATA/<network>/TEXT/RICELL
With this commit still the old data structures are used, until a flag in yacy.conf is set.
To switch to the new data structure, set
useCell = true
in yacy.conf. Then you will have no access any more to TEXT/RICACHE and TEXT/RICOLLECTION
This code is still bleeding-edge development. Please do not use the new data structure for
production now. Future versions may have changed data types, or other storage locations.
The next main release will have a migration feature for old data structures.

- 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.

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

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 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

ein 1.6er Target versehentlich zu setzen bedeutet bei automatischer Release-Erzeugung und updates bei Usern,
die nur Java 5 installiert haben (was bei allen Mac-Usern so ist), dass große Teile des Netzes crashen können und manuell
wieder hoch gezogen werden müssen.
Neu-User die mit einem dev-Release Beginnen können mit der intranet-Einstellung gar keine Websuche starten.
Bitte nach einem Commit immer kontrollieren, was man da eingecheckt hat.

- concurrency for LURL-fetching: this can be done using a concurrent lookup into the separated url databases. Concurrency is possible because there is no IO during lookup. The more LURL-Tables are present, the better is the speedup. More CPUs will increase speed
- because a large number of LURL-lookups are made during crawling (for double-check), the LURL-Lookup speed enhancements enhances also crawling speed
- search speed also profits from LURL-lookup enhancement
- changed some flushing parameters in word index caching which should make better use of large word index caches and should speed up indexing
- removed flush chunksize parameter, because this was only useful for IO path enhancement feature which was removed some weeks ago to prevent blocking and deadlocks during search requests

This data structure replaces almost all files in the PLASMA directory
also the collection.index and the LURL-db will be created as Eco-DB, if it does not exist before
existing Flex-databases will be used as they are (the is no data lost)
If you want to force the creation of a Eco-collection.index, simply delete the old index.
The Eco file system will only be used if there is enough memory.
The collection.index RAM limit is 200MB, if you have less, a flex-Table is createt.

a new release type was added: 'embedded' which is the same as the current standard release was
this will not have any effect to the next release 0.56, which will still a pro-release on public download
the transition the the new release strategy must be done now to enable automatic update by the updated in future releases

- 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

- removed web structure picture from indexing menu and grouped it together with htcache monitor
- added a database for terminated crawls, when a crawl is finished it is automatically moved to the new database
- extended crawl profile edit servlet, shows now also terminated crawls
- option that was used to delete profiles is now redesigned to a function that moves the current crawl to the terminated crawls and removes all urls from the current queues!
- fixed here and there problems with indexing queues
- enhances indexing speed by changing cache flush sizes.
- changed behaviour of crawl result servlet: the list of crawled urls is shown if there is one, othevise the overview window is shown
attention: the new profile databases are not compatible with the old one. current crawls will be lost! the web index is not touched.
next steps: the database of terminated crawls can be used to start with them a new crawl. This is useful if one wants to re-crawl specific pages and wants to use a old crawl profile.

- snippets are not fetched by browser using ajax, they are now fetched internally
- YaCy-internat threads control existence of snippets and sort out bad results
- search results are prepared using SSI includes
- the search result page is visible right after the search request, the results drop in when they are detected
- no more time-out strategy during search processes, results are shifted within queues when they arrive from remote peers
- added result page switching! after the first 10 results, the next page can be retrieved
- number of remote results is updated online on the result page as they drop in
- removed old snippet servelet (which had been also a security leak btw)
- media search is broken now, will be redesigned and fixed in another step

this saves about 1 millisecond for each URL reference, which has some good effect
on the search result computation if a word is searched that appears very often
(speed-up of 1 second and more)

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

- SSIs are streamed using chunked transfer, partly delivered pages can be seen in browser before transmission is finished
- added client-side network unit identification
- cleaned up code

- moved superseed file into new network unit definition
- fixed build; includes new network bootstraping files now

we will provide two different releases in the future, one standard release and one 'pro'-release.
the 'pro'-release contains all additional parsers AND has different default performance values.
The pro-version differs therefore from the previous 'all'-version by this default values.
The pro-configuration is automatically choosen if the libx-folder exists. If a version is once initialized, its configuration stays independently from an existing libx folder.
The ant targets had been changed. There are now 3 different targets to create standard and pro-releases, and one target to upgrade:
- dist: creates a standard release (only, no libx target any more)
- distPro: creates a pro-release (includes the libx)
- distExt: creates a libx-release which includes the libx-folder only. It may be used to upgrade from standard to pro
Furthermore, the naming of 'dev'-releases had been removed.

- all web page parsing operations will now increase a web structure file
- the file is computed in memory and dumped at shutdown-time to PLASMASB/webStructure.map in readable form (not a database)
- the file can be used externally to analyse the link structure of the crawled pages
- the web structure can also be retrieved using a xml-interface at http://localhost:8080/xml/webstructure.xml
- the short-term purpose is the computation of a link-graph image (before linuxtag!)
- a long-term purpose could be a decentralized computation of the citation rank
