YaCy Release 0.99

a update to ymarks (please test if you wish):
- import HTML (e.g. FF export) via /api/ymarks/import.html
- view your import via /api/ymarks/test.html
- get a xml list via /api/ymarks/get_ymark_list.xml?tags=&folders=
- delete bookmark tables via standard interface /Tables_p.html
it is still very experimental!!

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7248 6c8d7289-2bf4-0310-a012-ef5d649a1542

- enhanced DidYouMean computation using a faster count on index entries; this causes that results can be ranked better
- added limitations on DidYouMean result sets according to input and output string length

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7246 6c8d7289-2bf4-0310-a012-ef5d649a1542

enhancements in did-you-mean guessing

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7243 6c8d7289-2bf4-0310-a012-ef5d649a1542

more performance hacks
this makes YaCy search results VERY fast for all verify=false search cases
and it enhances the search speed also for all other snippet-fetch cases.
With this change my peer performed 100 Queries Per Second (!!!) while doing 10 queries simultanously (!!!)
in an intranet index of 20000 URLs on my 16-core Mac

Check this yourself by doing:
cd bin
./searchtestmulti.sh
after finishing the run, divide 1000 by the given time per query (which is the qps for one thread)
and then multiply again by 10 (because 10 search threads has been started)

- enhanced intranet search speed
- enhanced intranet portscan speed (better time-out)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7227 6c8d7289-2bf4-0310-a012-ef5d649a1542

de.lng: Added some more untranslated strings I found and uncommented old ones that were removed
terminal_p.html: Put back the old ID which was really easy to find
IndexCreate.js: Because XHTML 1.0 Strict does not allow name tags for some elements rewrote most element access functions to use getElementById
Table_API_p.html and all other html pages: Some XHTMl 1.0 Strict fixes, changed checkAll javascript, marked the first row with checkboxes as unsortable where applicable
Table_API_p.java and all other java pages: URLencoded lines with possible ampersands & -> & for validation XHTML 1.0 Strict sourcecode
--> All Index Create pages should validate now. Hope I did not break anything else (too much :-)


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7225 6c8d7289-2bf4-0310-a012-ef5d649a1542

- enhancements for search speed
- bug fixes in many classes including basic data structure classes

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7217 6c8d7289-2bf4-0310-a012-ef5d649a1542

fixed a number of small bugs:
- better crawl star for files paths and smb paths
- added time-out wrapper for dns resolving and reverse resolving to prevent blockings
- fixed intranet scanner result list check boxes
- prevented htcache usage in case of file and smb crawling (not necessary, documents are locally available)
- fixed rss feed loader
- fixes sitemap loader which had not been restricted to single files (crawl-depth must be zero)
- clearing of crawl result lists when a network switch was done
- higher maximum file size for crawler

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7214 6c8d7289-2bf4-0310-a012-ef5d649a1542

replaced auto-dom filter with easy-to-understand Site Link-List crawler option
- nobody understand the auto-dom filter without a lenghtly introduction about the function of a crawler
- nobody ever used the auto-dom filter other than with a crawl depth of 1
- the auto-dom filter was buggy since the filter did not survive a restart and then a search index contained waste
- the function of the auto-dom filter was in fact to just load a link list from the given start url and then start separate crawls for all these urls restricted by their domain
- the new Site Link-List option shows the target urls in real-time during input of the start url (like the robots check) and gives a transparent feed-back what it does before it can be used
- the new option also fits into the easy site-crawl start menu

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7213 6c8d7289-2bf4-0310-a012-ef5d649a1542

Collage.html and Collage.java: Added <p> in body before images for XHTML 1.0 Transitional validationg and alt tag to images as well as closing tag <img (...) />
terminal_p.html: Set new link for starting a crawl to CrawlStartSite_p.html and replaced the old embed object of the Among.us Flash object by their new JS which takes care of adding the object correctly
de.lng: Moved the translations for the JS part from yacyinteractive.html to the yacyinteractive.js part
--> Terminal page is now valid XHTML 1.0 Transitional


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7211 6c8d7289-2bf4-0310-a012-ef5d649a1542

ConfigLiveSearch.html: Fixed some HTML problems to validate at least XHTML 1.0 Transitional - strict is not possible because iframes are used. Replacing iframes with embedded object tag does not work in IE
ConfigPortal.html: Fixed some HTML problems to validate at least XHTML 1.0 Transitional - for strict the target attribute of the a link has to be removed
yacyinteractive.html: Moved all JS code to an external yacyinteractive.js file in JS folder
yacysearch.html: Removed embedded scripts from in between the body tags - now everything is loaded in the header
de.lng: Just in case JS files will be parsed at some point added translation for yacyinteractive.html result counter

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7208 6c8d7289-2bf4-0310-a012-ef5d649a1542

- moved yacybot user agent string definition to MultiProtocolURI since there are basic access mechanisms where the bot string is needed
- migrated the 'yacy' user agent to 'yacybot' in many client methods since the 'yacy' user agent is only used for the proxy

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7199 6c8d7289-2bf4-0310-a012-ef5d649a1542

simplified snippet computation process and separated the algorithm into two classes
also enhances selection criteria for best snippet line computation

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7182 6c8d7289-2bf4-0310-a012-ef5d649a1542

fixed several search bugs

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7180 6c8d7289-2bf4-0310-a012-ef5d649a1542

enhanced search speed:
- better control of number of running search threads
- no time-out waiting time when no ranking feeding takes place
- local search queries by a remote peer may be faster up to 300 milliseconds
- a local search may even be faster

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7176 6c8d7289-2bf4-0310-a012-ef5d649a1542

terminated migration from apache httpclient-3.1 to 4.1:
- remove the library
- added two classes from the httpclient-3.1 library as source code to YaCy because these classes were used by the YaCy HTTP Server
- modified the added classes ChunkedInputStream and ContentLengthInputStream in such a way that:
 * there are no more dependencies to httpclient-3.1
 * these classes had been simplified to serve only the purpose for the YaCy httpd

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7171 6c8d7289-2bf4-0310-a012-ef5d649a1542

*) Changed image in Steering.html from linked image to embedded image because shutdown is so fast now, browsers can't load image before Yacy instance is gone already. Had to make image smaller since IE does not accept large Base64 encoded images.
*) Decreases wait time in Steering.html before first check since 
*) HTML fixes

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7165 6c8d7289-2bf4-0310-a012-ef5d649a1542

- fixes for concurrency exceptions and failed database integrity verification
- added link to yacystats peer when peer is more than one day old

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7164 6c8d7289-2bf4-0310-a012-ef5d649a1542

- some layout and text enhancement for site crawl start
- Quix0rs patch from http://forum.yacy-websuche.de/viewtopic.php?p=20839#p20839 (parts)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7163 6c8d7289-2bf4-0310-a012-ef5d649a1542

enhanced remote crawling:
- 300 ppm is default now (but this is switched off by default; if you switch it on you may want more traffic?)
- better timing for busy queue
- better amount of remote url retrieval
- better time-out values
- better tracking of availability of remote crawl urls
- more logging for result of receipt sending

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7159 6c8d7289-2bf4-0310-a012-ef5d649a1542

- removed the remote crawl option from the network configuration submenu and
- added a remote crawl menu item to the index create menu. This menu also shows a list of peers that provide remote crawl urls
- set remote crawl option by default to off. This option may be important but it also confuses first-time users


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7158 6c8d7289-2bf4-0310-a012-ef5d649a1542

- corrected return value of put() methods (not used anywhere, so it did not harm before)
- added use of LookAheadIterator which should prevent mistakes when coding iterators with embedded iterators
- added a fail-safe reaction in case of database corruption using iterators over database elements (no interruption then)


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7154 6c8d7289-2bf4-0310-a012-ef5d649a1542

- code cleanup / added debug line for further investigation in HTTPDemon.parseMultipart
- changed data structure for sorting in search which performs better in that specific case (too many updates)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7150 6c8d7289-2bf4-0310-a012-ef5d649a1542

enhanced search event logging (to be used for further improvements)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7140 6c8d7289-2bf4-0310-a012-ef5d649a1542

redesign of the SortStack and SortStore classes:
created a WeakPriorityBlockingQueue as special implementation
of a PriorityBlockingQueue with a weak object binding.
- better abstraction of ordering technique
- fixed some bugs according to result numbering (distinguish different counters in Queue)
- fixed a ordering bug in post-ranking (ordering was decreased instead of increased)
- reversed ordering numbering using a reversed ordering. The higher the ranking number the better (now).

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7128 6c8d7289-2bf4-0310-a012-ef5d649a1542

- replaced pdfbox and fontbox version 1.1.0 with 1.2.1
- added some clear statements that shall clear static cache size within the pdfbox library
- the pdfbox library contains a memory leak; it is unsafe to run a peer with pdf parser permanently on.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7120 6c8d7289-2bf4-0310-a012-ef5d649a1542

change in handling of the all-visible home path for storage in YaCy:
the home path can now be distinguished between
- data home; the path where the DATA directory is created
- application home; everything else
This will make it possible to store application data on Mac releases within the
~/Library/YaCy
directory; a place where Mac applications write their data.
Similar techniques will be possible for debian and windows.
To use the new data path, YaCy can be started with
-start <data path>
or
-gui <data path>


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7092 6c8d7289-2bf4-0310-a012-ef5d649a1542

redesign of crawl profiles data structure. target will be:
- permanent storage of auto-dom statistics in profile
- storage of profiles in WorkTable data structure
not finished yet. No functional change yet.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7088 6c8d7289-2bf4-0310-a012-ef5d649a1542

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

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7074 6c8d7289-2bf4-0310-a012-ef5d649a1542

Support for indexing of RSS feeds!
- added a scanning in html parser for rss feeds
- storage of rss feed addresses, can be viewed with http://localhost:8080/Tables_p.html?table=rss
- rss items retrieved by http://localhost:8080/Load_RSS_p.html (in Index Creation menu) can be selected and indexed
- a rss feed retrieved in http://localhost:8080/Load_RSS_p.html can now be fully indexed
- indexing of rss feeds can be placed in scheduler

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7073 6c8d7289-2bf4-0310-a012-ef5d649a1542

- MapHeap now implements Map<byte[], Map<String, String>>
- refactoring of method names to comply with Map method names

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7072 6c8d7289-2bf4-0310-a012-ef5d649a1542

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)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7071 6c8d7289-2bf4-0310-a012-ef5d649a1542

preparations to move the HTCache into cora:
- move the header framework classes to cora
- move the ARC caching classes to cora
- refactoring of code to call these classes from cora

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7068 6c8d7289-2bf4-0310-a012-ef5d649a1542

- removed dependencies in header framework:
  moved http date methods from DateFormatter to HeaderFramework
  changed logging to log4j
- added ftp load access to MultiProtocolURI
- ensured termination of RSS feed iteration

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7067 6c8d7289-2bf4-0310-a012-ef5d649a1542

refactoring towards a unified loading mechanism for MultiProtocolURIs

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7065 6c8d7289-2bf4-0310-a012-ef5d649a1542

refactoring of the cora package to get subpackages for http and ftp (smb to come)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7063 6c8d7289-2bf4-0310-a012-ef5d649a1542

... migrating to HttpComponents-Client-4.x ...
The Client is dead, long live the Client!
(no references to the old client)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7060 6c8d7289-2bf4-0310-a012-ef5d649a1542

- added a new RSS reader interface. This is not finished but you can now load and look at RSS feeds. It will be used to index RSS feeds in a way that is appropriate for such kind of data.
- refactoring of Mediawiki and PHPBB3 loader interface names (just renamed)
- removed two old not used RSS loader interfaces
- fixed a bug in RSS parser library of cora
- added a new RSS parser component to the set of yacy document parsers

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7053 6c8d7289-2bf4-0310-a012-ef5d649a1542

added the new crawl scheduling function to the crawl start menu:
- the scheduler extends the option for re-crawl timing. Many people misunderstood the re-crawl timing feature because that was just a criteria for the url double-check and not a scheduler. Now the scheduler setting is combined with the re-crawl setting and people will have the choice between no re-crawl, re-crawl as was possible so far and a scheduled re-crawl. The 'classic' re-crawl time is set automatically when the scheduling function is selected
- removed the bookmark-based scheduler. This scheduler was not able to transport all attributes of a crawl start and did therefore not support special crawling starts i.e. for forums and wikis
- since the old scheduler was not aber to crawl special forums and wikis, the must-not-match filter was statically fixed to all bad pages for these special use cases. Since the new scheduler can handle these filters, it is possible to remove the default settings for the filters
- removed the busy thread that was used to trigger the bookmark-based scheduler
- removed the crontab for the bookmark-based scheduler

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7051 6c8d7289-2bf4-0310-a012-ef5d649a1542

added a scheduler based on API actions
- every process that is monitored with the API Steering interface can now be scheduled!
- added input methods in Steering interface to set a scheduling time
- added a view on the steering api that shows only crawl jobs inside the Crawl Profile servlet
- added a scheduling call process in the cleanup process handler that triggers the scheduled processes
This causes that the cleanup now also looks for scheduled processes. Such processes are therefore not executed at
the same time as given in the target execution time but they will be executed within the cleanup process time window.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7050 6c8d7289-2bf4-0310-a012-ef5d649a1542

- 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 (  in spaces of date format)


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7049 6c8d7289-2bf4-0310-a012-ef5d649a1542

- the web visualization can now be generated in custom color
- added input fields in WatchWebStructure_p.html
- introduced enum classes for Draw Mode and Filter Mode

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7044 6c8d7289-2bf4-0310-a012-ef5d649a1542

- better url double check in crawler
- more logging for error urls

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7032 6c8d7289-2bf4-0310-a012-ef5d649a1542

- removed unused network oanet
- added new network definition 'allip' which can be used in networks where intranet and internet-addresses shall be indexed
- added a auto-switch-off for global search if there are no global peers

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7030 6c8d7289-2bf4-0310-a012-ef5d649a1542

added a Macintosh OSX application wrapper.
You can now create a YaCy Mac application like this:
- build a new version of YaCy
- take everything that is in the yacy home directory (from the fresh build) and move it into a copy of the YaCy.app directory under YaCy.app/Contents/Resources/Java/
- ready: double-click the YaCy.app icon and the new YaCy gui starts, then the browsers is also opened.
- if the Mac application is terminated, also the YaCy demon should be stopped automatically and vice versa. This is currently not really good working and needs some more care.
A build script for this is missing. Does anyone know how to do that in ant?

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7023 6c8d7289-2bf4-0310-a012-ef5d649a1542

added a very early test version of a YaCy gui component.
The gui currently does nothing else than providing a search window that sends the search string to the browser
The gui is started when YaCy is started with the option -g or --gui, like
./startYACY.sh -g
The gui will primary be used to provide a 'real' macintosh version that can be started and operated like any other macintosh application. A special mac application wrapper will follow.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7021 6c8d7289-2bf4-0310-a012-ef5d649a1542

better memory management and slightly less (in total and temporary) RAM allocation:
- confirm that database objects that are not supposed to grow do not have a index memory management that is designed for growth

better (and corrected) recognition of intranet and internet-addresses. This corrects the isLocal property that is used by network definitions to restrict index ranges to local and global addresses. Address locations (intranet or internet) had been partly identified by the top level domain of the host address. Since intranet addresses can also be addressed using a host name that is in a country domain it is necessary to do a dns resolving for each check. The check is supported by a local dns cache so the intranet/internet check should not affect network traffic too much. To ensure that the cache works properly the cache class was upgraded to better concurrency data structures.

redesign of parser interface:
some file types are containers for several files. These containers had been parsed in such a way that the set of resulting parsed content was merged into one single document before parsing. Using this parser infrastructure it is not possible to parse document containers that contain individual files. An example is a rss file where the rss messages can be treated as individual documents with their own url reference. Another example is a surrogate file which was treated with a special operation outside of the parser infrastructure.
This commit introduces a redesigned parser interface and a new abstract parser implementation. The new parser interface has now only one entry point and returns always a set of parsed documents. In case of single documents the parser method returns a set of one documents.
To be compliant with the new interface, the zip and tar parser had been also completely redesigned. All parsers are now much more simple and cleaner in its structure. The switchboard operations had been extended to operate with sets of parsed files, not single parsed files.
additionally, parsing of jar manifest files had been added.

added a configuration page for search heuristics. currently you can switch on there:

- removed the UPnP library sources from sbbi and added the jar library again. The library was included to get support for fedora releases, but after this time the fact that the sbbi cannot be part of fedora should be re-discussed. If this will still not be possible, then we may integrate the sbbi UPnP package using reflection.
- cleaned uo the code. The new eclipse helios provided new warnings for dead code. This change cleans up most of these warnings

added a 'transition feature' that shall lower the barrier to move from g**gle to yacy (yes!):

Here a new concept called 'search heuristics' is introduced. A heuristic is a kind of 'shortcut' to good results in IT, here for good search results. In this case it will be used to get a very transparent way to compare what YaCy is able to produce as search result and what g**gle produces as search result. Here is what your can do now:
- add the phrase 'heuristic:scroogle' to your search query, like 'oil spill heuristic:scroogle' and then a call to scroogle is made to get anonymous search results from g**gle.
- these results are _not_ taken as meta-search results, but are used to instantly feed a crawling and indexing process. This happens very fast, here 20 results from scroogle are taken and loaded all simultanously, parsed and indexed immediately and from the results of the parsed content the search result is feeded, along to the normal p2p search
- when new results from that heuristic (more to come) get part of the search results, then it is verified if such results are redundant to existing (they had been part of the normal YaCy search result anyway) or if they had been completely new to YaCy.
- in the search results the new search results from heuristics are marked with a 'H ++' and search results from heuristics that had been already found by YaCy are marked with a 'H ='. That means:
- you can now see YaCy and Scroogle search results in one result page but you also see that you would not have 'missed' the g**gle results when you would only have used YaCy.

- to make it short: YaCy now subsumes g**gle results. If you use only YaCy, you miss nothing.

to come: a configuration page that let you configure the usage of heuristics and get this feature by default.

added a fascinating new way to search _and_ start a web crawl at the same time:
implemented a hint from dulcedo "use site: - operator as crawl start point".
YaCy already was able to search using a site-constraint. This function is now extended with a instant crawling feature.
When you now use the site-operator, then the landing page of the site iand every page that is linked from this page are loaded, indexed and selected for the search result within that search request. When the remote server responds quickly enough, then this process can result in search results during the normal search result preparation .. just in some seconds.

more abstraction for access of LoaderDispatcher and cache

more abstraction of the htcache when using the LoaderDispatcher:
a cache access shall not made directly to the cache any more, all loading attempts shall use the LoaderDispatcher.
To control the usage of the cache, a enum instance from CrawlProfile.CacheStrategy shall be used.
Some direct loading methods without the usage of a cache strategy have been removed. This affects also the verify-option
of the yacysearch servlet. If there is a 'verify=false' now after this commit this does not necessarily mean that no snippets
are generated. Instead, all snippets that can be retrieved using the cache only are presented. This still means that the search hit was not verified because the snippet was generated using the cache. If a cache-based generation of snippets is not possible, then the verify=false causes that the link is not rejected.

- scanned remote search process and enhanced some data structure and synchronizations here and there
- removed concurrency overhead for small number of index normalizations as it happens during remote search
- removed 'load only parseable' constraint for snippet fetch because some resources may not have any url file extension and these had therefore not been parseable and searcheable since they may become parseable after loading when their mime type is known
- this partly fixes some problems with http://forum.yacy-websuche.de/viewtopic.php?p=20300#p20300 but more changes are necessary to get all expected search results

removed finalize methods because of a hint in
http://java.sun.com/javase/6/webnotes/trouble/TSG-VM/html/memleaks.html#gbyvh

The finalize method prevents that the memory, used by the objects containing the finalize method, is collected and available for the garbage collector. Instead, the memory allocated by such classes are enqueued to a java-internal finalize queue runner. This slows down all operations that uses a lot of object containing finalize methods.

this fix does not remove all finalize method, but such that may be used for throw-away objects that are allocated many times. This should cause a better run-time performance and less OutOfMemoryErrors 

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6835 6c8d7289-2bf4-0310-a012-ef5d649a1542

enhanced remove() operation: in many cases it is not necessary to return the removed object to the called.
for such cases the delete() operation was introduced which is sometimes much cheaper in operation since it does not need to create objects to hold the removed content and it does not need to read those objects.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6824 6c8d7289-2bf4-0310-a012-ef5d649a1542

enhanced remove operation in search consequences (which are triggered when the snippet fetch proves that the word has disappeared from the page that was stored in the index)
- no direct deletion of referenced during search (shifted to time after search)
- bundling of all deletions for the references of a single word into one remove operation
- enhanced remove operation by caring that the collection is stored sorted (experimental)
- more String -> byte[] transition for search word lists
- clean up of unused code
- enhanced memory allocation of RowSet Objects (will use a little bit less memory which was wasted before)

a collection of performance hacks and code cleanup:
- removed usage of URL-Caches which could have been a memory leak
- removed unused classes and methods
- removed not necessary synchronizations
- added synchronization hacks where possible
- fine-tuned crawling speed to prevent IO of balancer
- fixed a bug in IODispatcher that may have caused that no merges were done
- reduced number of parameters in very often called methods (compare methods)
- reduced complexity of data structures of now massively used HandleSet class
- reduction of new String() and getBytes() usage / new methods to support this transition

- enhanced the Balancer performance when building new domain stacks using a new Table buffer
- added the new Table buffer BufferedObjectIndex class
- changed order of access to LURL-read (prefereing segment over Crawl Queues) will reduced blocking time on balancer
- fixed PPM setting in Crawler_p servlet (had doubled values)
- reduced synchronization in IndexCell because it is not necessary: reduced blocking during indexing/merging/dumping
- removed did-you-mean cache in IndexCell because that caused too much overhead and more memory usage but was not very useful. This reduced also deadlocks that could be causes when searched are performed during indexing.

changed way how number of search requests are counted:
so far only search requests at the remote search interface had been counted.
This was done to protect the privacy of searchers, because counting was not done and published at the own search interface.
This caused that no search requests of robinson peers had been counted, becuase they cannot be counted at remote peer.
This change introduces a distinction of locally done search requests at the local search interface from search requests that are on the local interface but had been submitted from a remote IP without authentication.
Now 3 counters are maintained:
- partial count of remote searches
- total count of local searches on robinson peers from non-authenticated clients
- total count of local searches on robinson peers from localhost or authenticated clients
In the global statistic of search requests now the first two counters of the three cases are added
Because we habe a large number of robinson peers with a large number of remote non-authenticated requests the statistic should show at least three times of the number of search requests.

refactoring of bookmarks: there is a big performance problem in the bookmarks code and furthermore the bookmarks
will loose its leading role for the re-crawl funtion when the new api tables will work. To be prepared for a replacement
of such functions the bookmark class is re-organised.

update to yacy/ai (just more testing)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6607 6c8d7289-2bf4-0310-a012-ef5d649a1542

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

renamed the servlet WatchCrawler_p to Crawler_p
this was done because that servlet may be used for wget/cronjob

name of the crawl start servlet looks like a pure monitoring tool.

some redesign of the main menu structure:
- moved all index generation servlets to it's own main menu item, including proxy indexing
- removed external index import because this operation is not recommended any more. Joining an index can simply be done by moving the index files from one peer to the other peer; they will be merged automatically
- fix to prevent endless loops when disconnecting http sessions
- fix to prevent application of bad blacklist entries that can cause a 'Dangling meta character' exception

Added new classes for the implementation of concurrent greedy algorithms.
These classes can be used to produce an abstract worker process that can be used for common problems in artificial intelligence, such as game playing and problem solving. These classes will be used as abstraction layer for a new search process in YaCy. These classes had been created while searching for an abstraction of the current search process. It turned out that the abstraction of the YaCy search process is also an abstraction for problems in artificial intelligence and therefore the classes had been designed in such a way that it covers not only the YaCy-specific problem but also the more generic problems in ai. To test the classes they had been used in a ConnectFour implementation (game playing).

replaced _all_ size() == 0 with isEmpty() and all size() > 0 with !isEmpty(). The isEmpty() method is much faster in some cases, especially when used to access badly balanced hashtables where an size() operation becomes a large iteration.

very first working version of oai-pmh importer: if given the right url, the importer can read and index listRecord xml files and calculate the right resumptionURL which is then given as next default start point for the importer url input.
no automatic harvesting by now, this will be done later

- extended the OAI-PMH test applet and integrated it into the menu. Does still not import OAI-PMH records, but shows that it is able to read and parse this data
- some redesign in ZURL storage: refactoring of access methods, better concurrency, less synchronization
- added a limitation to the LURL metadata database table cache to 20 million entries: this cache was until now not limited and only limited by the available RAM which may have caused a memory-leak-like behavior.

*) Made sure that only files with appropriate file endings are listed as skin or language files.
*) Introduced protection against directory traversal attacks in configuration servlets for skin and language configuration. Files can only be deleted if they are contained in a list of files which has been read by the servlet first.


Until now it was possible to delete any data on a system YaCy is running on and which can be deleted by the user who's account has been used to start YaCy. Most of the times a user of YaCy is also the owner of the machine the peer is running on, but this might not always be the case and not even the owner of the machine should be able to use YaCy as a replacement for "rm" or "del".

* added index segments
This is a major change in the organization of indexes.
Please consider a back-up of your data before you run this update.
All existing index files will be moved and renamed to a new position.
With this change, it will be possible to maintain different indexes for different purposes and it will be possible to have a distinction between DHT-in and DHT-out specific indexes. Tenants may also have their own index, and it may be possible to have histories and back-ups of indexes. This is just the beginning, many servlets must be adopted after this change, but all functions that had been there should still work.

*) blacklist cleaner supports usage of regular expressions now
*) refacored BlacklistCleaner_p.java for better readability
*) moved check of validity of patterns to the Balcklist implementation since patterns might be valid in one implementation, but not in another
*) added method to check validity to Blacklist interface
*) fixed some minor issues like typos or wrong whitespaces
*) set subversion properties for a whole bunch of files

*) Removed base tag from errror page. This has been added by myself a long time ago as a workaround for some weird behavior of my router, but as it turns out, it does more bad than good in general: If HTTPS is used for communication with YaCy, entering a wrong passwort led to an errror page with a form which would send username and password unencrypted with the user possibly being unaware of this.
*) changed some comments, added some annotations, added SVN properties here and there

- inserted new library tests inside DidYouMean
- some redesign of DidYouMean that was necessary to follow
  a special rule how a library should be used:
  - the library provides words that start or end with a test
    word which may be possibly also an empty set of words
  - all words that the DidYouMean produced with the four
    production rules are used to generate a set of
    library-completed words
  - if this process results in any words from the library,
    only library-genrated words are taken
  - if the is no library-generated word at all, take the
    artifial generated word
  - all words that result from these rules are tested against
    the index
  - the result is ordered using a lightweight comparator that
    prefers short words
  - a not-so-much-io test against the index is beeing prepared
    next
- insered the library initialization into the switchboard

added a library provider which holds libraries in static objects,
which can be used by any other classes to support their functions.
libraries are designed in such a way that users can create and
insert their own library files, but can also be imported from
other sources. As an example the "Korpusbasierte Wortgrundformliste
DeReWo des Institut für Deutsche Sprache" from
http://www.ids-mannheim.de has been integrated. This dictionary
is licensed to be used for all non-profit purposes. In case that
YaCy is used for commercial uses, this library must be removed.
The new library provilder reads the original source and translates
it into a simple word list to be used for the did-you-mean library
provider. More libraries may be provided in the future using
a download-servlet which puts files from the internet into the
<application-root>/dictionaries/ path.

some performance hacks (CPU only, not IO)
this will cause better computation speed for single- and multi-core;
there are enhancements that will speed up old and slow machines as well
as multi-core CPUs. Indexing of surrogates has been speed up
from 4000 PPM to over 20000 PPM on a simple dual core office computer.
Since the enhancements are mostly in core routines, the hack should also
speed up search performance.

refactoring of search process.
this is the beginning of some architecture changes that will hopefully bring some more stability, speed and transparency to the search process.

- patch to omit IndexOutOfBoundsException when a b64-encoded key appears not to be well-formed. In that case the key is still accepted but rated higher than other regular keys to create a virtual ordering between well-formed and ill-formed keys
- check routine at the beginning of the import of table keys that check that all imported keys are well-formed. All records that have a ill-formed key are deleted. This is a hack and is not tested since I don't have bad data here to test with. If the effect is seen in the wild, please report in the forum.

- fixes for some problems with the new crawling/caching strategies
- speed enhancements for the cache-only cache policy by using special no-delay rules in the balancer

redesign of access to the HTCache (now http.client.Cache):
- better control to the cache by using combined request-header and content access methods
- refactoring of many classes to comply to this new access method
- make shure that the cache is always written if something was loaded
- some redesign of the process how http response results are feeded into the new indexing queue
- introduction of a cache read policy:
 * never use the cache
 * use the cache if entry exist
 * use the cache if the proxy freshness rule confirmes
 * use only the cache and go never online
- added configuration options for the crawl profiles to use the new cache policies. There is not yet a input during crawl start to set the policy but this will be added in another step.
- set the default policies for the existing crawl profiles. If you want them to appear in your default profiles you must delete the crawl profiles database; othervise the policy is 'proxy freshness rule'
- enhanced some cache access methods in such a way that unnecessary retrievals are omitted (i.e. for size computation). That should reduce some IO but also a lot of CPU computation because sizes were computed after decompression of content after retrieval of the content from the disc.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6239 6c8d7289-2bf4-0310-a012-ef5d649a1542

refactoring:
- removed the plasma package. The name of that package came from a very early pre-version of YaCy, even before YaCy was named AnomicHTTPProxy. The Proxy project introduced search for cache contents using class files that had been developed during the plasma project. Information from 2002 about plasma can be found here:
http://web.archive.org/web/20020802110827/http://anomic.de/AnomicPlasma/index.html
We stil have one class that comes mostly unchanged from the plasma project, the Condenser class. But this is now part of the document package and all other classes in the plasma package can be assigned to other packages.
- cleaned up the http package: better structure of that class and clean isolation of server and client classes. The old HTCache becomes part of the client sub-package of http.
- because the plasmaSwitchboard is now part of the search package all servlets had to be touched to declare a different package source.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6232 6c8d7289-2bf4-0310-a012-ef5d649a1542

removed the indexing queue. This queue was superfluous since the introduction of the blocking queues last year, where documents are parsed, analysed and stored in the index with concurrency.
- 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.

serialized all logging using concurrency:
high-performance search query situations as seen in yacy-metager integration showed deadlock situation caused by synchronization effects inside of sun.java code. It appears that the logger is not completely safe against deadlock situations in concurrent calls of the logger. One possible solution would be a outside-synchronization with 'synchronized' statements, but that would further apply blocking on all high-efficient methods that call the logger. It is much better to do a non-blocking hand-over of logging lines and work off log entries with a concurrent log writer. This also disconnects IO operations from logging, which can also cause IO operation when a log is written to a file. This commit not only moves the logger from kelondro to yacy.logging, it also inserts the concurrency methods to realize non-blocking logging.

tried to insert a database dump import method to the phpBB3 import function. Reason: imports or large database dumps are cannot be handled with phpMyAdmin and this should be an easy way to the database dumps into a mySQL database where it can be exported again with the phpBB3 content integration adapter. Completion or removal of this function stub will follow before next main release.

- refactoring of IntegerHandleIndex and LongHandleIndex: both classes had been merged into the new HandleMap class, which handles (key<byte[]>,n-byte-long) pairs with arbitraty key and value length. This will be useful to get a memory-enhanced/minimized database table indexing.
- added a analysis method that counts bytes that could be saved in case the new HandleMap can be applied in the most efficient way. Look for the log messages beginning with "HeapReader saturation": in most cases we could save about 30% RAM!
- removed the old FlexTable database structure. It was not used any more.
- removed memory statistics in PerformanceMemory about flex tables and node caches (node caches were used by Tree Tables, which are also not used any more)
- add a stub for a steering of navigation functions. That should help to switch off naviagtion computation in cases where it is not demanded by a client

more refactoring to make the segment object easier to use and to be prepared to integrate author navigation

refactoring of plasmaWordIndex:
divided that class into three parts:
- the peers object is now hosted by the plasmaSwitchboard
- the crawler elements are now in a new class, crawler.CrawlerSwitchboard
- the index elements are core of the new segment data structure, which is a bundle of different indexes for the full text and (in the future) navigation indexes and the metadata store. The new class is now in kelondro.text.Segment

The refactoring is inspired by the roadmap to create index segments, the option to host different indexes on one peer.

migration of all databases that use the deprecated BLOBTree format into the BLOBHeap format. Old databases are migrated automatically.
This removes the last very IO-intensive data structures which were still used for Wiki, Blog and Bookmarks. Old database files will still remain in the DATA subdirectory but can be deleted manually if no major bugs appear during migration. There is no need for any user action, all migration is done automatically.

first attempt to add 'real' Navigation to yacy search results: host navigation
- after a search is started, it is analysed how many hits are in each site
- this can be done really efficient, because the navigation information is hidden in the url hash and can be computed very fast
- the search result shows a column on the right with the hosts and the hits per host
- after a click on a host the search is modified using the efficient site: - operator

attempt to fix a deadlock situation where the IODispatcher did not work.
I suspect the dispatcher thread has crashed and queues filled so no indexing process was able to write data.
This fix tries to heal the problem, but I am unsure if it helps. To get a better view of the problem, some more log outputs had been inserted.
Added also a new attribut indexer.threads to get a control over the number of default threads for the indexer (default is 1)

To translate a mediawiki dump into the YaCy surrogate format do the following:
- download a wikipedia dump, i.e. dewiki-20090311-pages-articles.xml.bz2
from http://download.wikimedia.org/dewiki/20090311/
- move dewiki-20090311-pages-articles.xml.bz2 to DATA/HTCACHE/
- start the conversion; open a command shell, move to the yacy home directory and execute
java -Xmx2000m -cp classes:lib/bzip2.jar de.anomic.tools.mediawikiIndex -convert DATA/HTCACHE/dewiki-20090311-pages-articles.xml.bz2 DATA/SURROGATES/in/ http://de.wikipedia.org/wiki/

this generates a series of files to DATA/SURROGATES/in

if YaCy is running (it may run concurrently), it fetches all new dumps in the surrogate-in directory. The export process is transaction-save, that means YaCy will not start reading a dump while the dump is not completely finished.

two patches for performance enhancements of the index handover process from documents to the index cache:
- one word prototype is generated for each document, that is re-used when a specific word is stored.
- the index cache uses now ByteArray objects to reference to the RWI instead of byte[]. This enhances access to the the map that stores the cache. To dump the cache to the FS, the content must be sorted, but sorting takes less time than maintenance of a sorted map during caching.

full redesign of index access data model:
terms (words) are not any more retrieved by their word hash string, but by a byte[] containing the word hash.
this has strong advantages when RWIs are sorted in the ReferenceContainer Cache and compared with the sun.java TreeMap method, which needed getBytes() and new String() transformations before.
Many thousands of such conversions are now omitted every second, which increases the indexing speed by a factor of two.

- added Latency control to the crawler:
because of the strongly enhanced indexing speed when using the new IndexCell RWI data structures (> 2000PPM on my notebook), it is now necessary to control the crawling speed depending on the response time of the target server (which is also YaCy in case of some intranet indexing use cases).
The latency factor in crawl delay times is derived from the time that a target hosts takes to answer on http requests. For internet domains, the crawl delay is a minimum of twice the response time, in intranet cases the delay time is now a halve of the response time.

- added API to monitor the latency times of the crawler:
a new api at /api/latency_p.xml returns the current response times of domains, the time when the domain was accessed by the crawler the last time and many more attributes.

Integration of the new index data structure IndexCell
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.

more performance hacks: better default values for scaling, less memory usage

replaced old PPM computation with a better one that simply sums up events that had been stored in the profiling table.

added new class RowSetArray which arranges RowSet objects like Elements in a hashtable, but still provides the functionality of sorted enumeration. The new class is now integrated into the ObjectIndexCache, which is the core class to provide index functions to all database files. The new index access is about twice as fast as before. This has strong speed enhancement effects on all parts of YaCy.

The speed of the kelondro indexing class ObjectIndexCache can be compared with Javas standard TreeMap with the main method in IntegerHandleIndex. The result is, that the kelondro indexing needs only 1/5 of the memory that TreeMap uses! In exchange, the kelondro classes are slower than TreeMap, about four (!) times slower. However, this is not so bad because the better use of the memory is a strong advantage and makes it possible that YaCy can maintain such a large number of document (> 50 million) in one peer.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5705 6c8d7289-2bf4-0310-a012-ef5d649a1542

performance hack to ObjectIndex put() method:
Java standard classes provide a Map Interface, that has a put() method that returns the object that was replaced by the object that was the argument of the put call. The kelondro ObjectIndex defined a put method in the same way, that means it also returned the previous value of the Entry object before the put call. However, this value was not used by the calling code in the most cases. Omitting a return of the previous value would cause some performance benefit. This change implements a put method that does not return the previous value to reflect the common use. Omitting the return of previous values will cause some benefit in performance. The functionality to get the previous value is still maintained, and provided with a new 'replace' method. 

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5700 6c8d7289-2bf4-0310-a012-ef5d649a1542

added also an export and delete-feature to the URLAnalysis. This completes the clean-up feature for URLs. To do a complete clean-up of the url database, start the following:
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -incollection DATA/INDEX/freeworld/TEXT/RICOLLECTION used.dump
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -diffurlcol DATA/INDEX/freeworld/TEXT used.dump diffurlcol.dump
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -export DATA/INDEX/freeworld/TEXT xml urls.xml diffurlcol.dump
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -delete DATA/INDEX/freeworld/TEXT diffurlcol.dump

The export-feature is optional, the purpose of that function is to provide a back-up function for URLs to be deleted. The export function can also be used to create html files with embedded links and simple text-files. Simply replace the 'xml' word with 'html' or 'text'. The last argument in the cann, the diffurlcol.dump value, can also be omitted. This will cause that the complete URL database is exported. This is an alternative to the Web-Interface based export function.

The delete-feature is the only destructive method of the four presented here. Please use it with care. It is better to make a back-up of the url database files before starting the deletion.


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5694 6c8d7289-2bf4-0310-a012-ef5d649a1542

added next tool for url analysis: check for references, that occur in the URL-DB but not in the RICOLLECTIONS
to use this, you must user the -incollection command before (see SVN 5687) and you need a 
used.dump file that has been produced with that process.

Now you can use that file, to do a URL-hash compare with the urls in the URL-DB. To do that, execute
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -diffurlcol DATA/INDEX/freeworld/TEXT used.dump diffurlcol.dump
or use different names for the dump files or more memory.

As a result, you get the file diffurlcol.dump which contains all the url hashes that occur in the URL database, but not in the collections.
The file has the format
{hash-12}*
that means: 12 byte long hashes are listed without any separation.

The next step could be to process this file and delete all these URLs with the computed hashes, or to export them before deletion.

added new row interator in kelondro tables files that enumerates rows
without an order by the primary key. The result is a very fast enumeration of the Eco table data structure. Other table data types are not affected.
The new enumerator is used for the url export function that can be accessed from the online interface (Index Administration -> URL References -> Export). This export should now be much faster, if all url database files are from type Eco
The new enumeration is also used at other functions in YaCy, i.e. the initialization of the crawl balancer and the initialization of YaCy News.

replaced old DHT transmission method with new method. Many things have changed! some of them:
- 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.

added new cybertag-tracking feature that was inspired by itgrl
from the forum discussion in
http://forum.yacy-websuche.de/viewtopic.php?p=12612#p12612

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

the Semantic Web moves in!
- added two new api files for document metadata:
- added a XHTML+RDFa html file shows the document metadata in a format that presents the data for rendering and for metadata retrieval. This is a typical document format for a semantic web data structure. the used RDF vocabulary is Dublin Core
- added a xml file that shows the same data as pure DC metadata
- integrated the API into the existing IndexControlURLs interface

With about one billion metadata files (URL metadata) this extension makes the freeworld YaCy network
to one of the probably largest metadata document provider for the semantic web!

added an access control to the search interface using white/blacklists:
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 reader and visualization for mediawiki-export files:
files exported from mediawiki using the xml schema according to
http://www.mediawiki.org/xml/export-0.3/
can be processed to be viewed in a YaCy servlet.
To acces such a file, place it into
DATA/HTCACHE/mediawiki/
i.e. the export from german wikipedia would be:
DATA/HTCACHE/mediawiki/wikipedia.de.xml
This file can then be accessed using the URL
http://localhost:8080/mediawiki_p.html?dump=wikipedia.de.xml&title=YaCy
if this is done the first time, an index file is created
(for this case: more than 4 million lines must be written, this takes about 15 minutes)
Then try the same url again.

- enhanced also the md5 computation speed

extended crawling constraints:
- 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)

FULL redesign of algorithms in htmlTools to encode/decode strings from/to unicode and html.
The old process used a not really efficient way to detect html encoding strings in texts.
All calling methods had been adoped to call the new class in an enhanced way with less parameters.

Many classes in interfaces used a XML encoding only (instead of full html conversion from unicode to html); this behavior was not changed with this commit but should be controlled again since it points out possible XSS leaks

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5295 6c8d7289-2bf4-0310-a012-ef5d649a1542

added test files for UTF-8 / Umlaute - Testing:
These 3 files contain the same text in different HTML encodings. We use this documents to test if the parser and indexer creates the same set of word hashes for all three texts.

To use these files, run a indexing/crawling on them. To get the files inside the localhost-path, do the following:

cd <yacy-home>
rmdir DATA/HTDOCS/repository
ln -s test/parsertest DATA/HTDOCS/repository

you have then linked the test directory as repository directory which you can reach in yacy if you switch to intranet indexing mode. So the next step is to start yacy, then
- switch to intranet use case
- go to the crawl start page
- the repository directory should be the default path as crawl start
- start the crawl
- search for any word that appears in the demo texts
- search not only for words with umlautel but also for words without umlaute to ensure that you find _all_ three documents
- see how yacy presents the snippet with the text containing umlaute

added another class to handle BLOB writings to the new HTCACHE data storage:
- 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

refactoring and new architecture to store the files of the web cache:
- 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.

fixed bug with wrong proxy result enqueueing. See:
http://forum.yacy-websuche.de/viewtopic.php?p=8130#p8130
- removed the online status property. This influenced the proxy behavior and created some complexity that was not needed because the online status was never used as it was ceated for (offline browsing)
- checked all proxy identification procedures during crawling and enhanced transparency and error checking
- fixed a proxy identification routine that caused the wrong selection of the proxy result queue

discovered and removed a (possibly large) memory leak:
many classes used the kelondroMapDataMining (was: kelondroMapObjects) which adds statistical
functions to the kelondroMap (was: kelondroObjects), but these functions were not used by these
classes. Especially the HTCACHE and robots.txt database allocate a very large number of objects
for statistical use, but never used them. By replacing the kelondroMapDataMining with the
kelondroMap object for these classes now less memory is allocated.


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4986 6c8d7289-2bf4-0310-a012-ef5d649a1542

Major update to BLOB data structures:
- 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


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4978 6c8d7289-2bf4-0310-a012-ef5d649a1542

added many missing user-agent declarations for yacy http client connections.
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

- modified and enhanced the crawl balancer: better list export, fixing of damaged crawl queue at start-up, re-sorting at start-up to enhance domain order
- 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

modified the diskUsage class regarding the following two aspects:
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.

refactoring:
find a better way to store BLOBs; generalize current BLOG data structure (kelondroDyn)
and prepare it to replace it with something better. The best candidate is the kelondroHeap,
which will become the kelondroBLOBHeap;
removed also some never-used classes

implemented switch for admin authorization from localhost:
- 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

major step forward to network switching (target is easy switch to intranet or other networks .. and back)
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

- modified, simplified old kelondroHTCache object; I believe it should be replaced by something completely new
- removed tree data type in kelondroHTCache
- added new class kelondroHeap; may be the core for a storage object that will once replace the many-files strategy of kelondroHTCache
- removed compatibility mode in indexRAMRI

added new news window into the status page. At this moment it is just a test.
The news inside the window are about peer arrivals and departures, remote search accesses and crawls

small corrections and enhancements after search timing profiling
search should be a little bit faster now

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4734 6c8d7289-2bf4-0310-a012-ef5d649a1542

added new default profiles to distinguish snippet fetch for local and global search
the difference is, that a local search will no not cause a re-indexing of loaded pages

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4731 6c8d7289-2bf4-0310-a012-ef5d649a1542

- refactoring of Colage back-end: move to plasma package
- renamed also the plasmaCrawlResults to have a consistent naming for url and image queues
- added a double-check for the images
- added additional queues for the images: all worse-quality images go there, so the queue can be used also if no sizes are given; no image is lost
- added a cleanup for the stacks so they cannot flood the memory

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4722 6c8d7289-2bf4-0310-a012-ef5d649a1542

- made usage of BufferedStreams explizit to distinct different copy method in serverFileUtils (byte-by-byte and using an own buffer)
- introduced another timeout setting (java internal property)
- more restrictions to clients accessing a single host (a security setting to prevent DoS by mistake)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4674 6c8d7289-2bf4-0310-a012-ef5d649a1542

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4667 6c8d7289-2bf4-0310-a012-ef5d649a1542

fix for http://forum.yacy-websuche.de/viewtopic.php?p=6806#p6806
- removed all InputStream.available() because this does not work for files > 2GB
- iterator terminate when a IOException occurs
- added handling of non-executing index.add methods to enhance assert usage
- added index for file indexes > 2GB, to be used in new indexHeap

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4666 6c8d7289-2bf4-0310-a012-ef5d649a1542

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4640 6c8d7289-2bf4-0310-a012-ef5d649a1542

strong speed enhancements for the index cache dump and restore:
storage and loading is 30 times faster! a cache of 100000 RWIs needed 180 seconds
to store and 100 seconds to restore; now the same cache needs only 6 seconds to store and
3 seconds to restore. The cache size has decreased now by 30% (95 MB instead of 150 MB).

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4634 6c8d7289-2bf4-0310-a012-ef5d649a1542

speed enhancements for crawler and url retrieval (affects also search speed)
- 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

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4628 6c8d7289-2bf4-0310-a012-ef5d649a1542

enhanced the concurrency handling of indexing process (better queue size control, better data concept, better shutdown behavior)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4617 6c8d7289-2bf4-0310-a012-ef5d649a1542

added concurrency to indexing process:
- the methods {parsing, semantic analysis (condensing), structure analysis (web structure)} in the serialized indexing path had been made concurrent.
- four BlockingQueues handle concurrency and hand-over of the indexing objects, the last object in the queue is stored into a blockingQueue of maximum size 1 to serialize the process for storage (which uses IO and therefore here should not be deserialized)
- a concurrency of (CPUs + 1) is default. Single-CPU users will profil from the change because large files cannot block the indexing process any more.
- removed the secondary indexing thread, which is superfluous now. Concurrency is default for all users.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4609 6c8d7289-2bf4-0310-a012-ef5d649a1542

- refactoring of serverThreads: renaming to distinguish busy-threads and blocking-threads
- added blockingThreads which are threads that are not driven by pause times but by BlockingQueue lookup

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4606 6c8d7289-2bf4-0310-a012-ef5d649a1542

- preparation of parsing/indexing queue for concurrent execution
- 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

- refactoring and abstraction of index reference (urls) handling: blacklisting is part of reference filtering
- refactoring of word/phrase handling: word abstraction from condenser becomes part of index element handling
- removed unused code parts from condenser

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4603 6c8d7289-2bf4-0310-a012-ef5d649a1542

- separated the LURL data storage and Crawl result stack for process supervision.
  this is another step to enable multiple, concurrent fulltext-indexes
- another try to make the yacy-httpc more stable

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4602 6c8d7289-2bf4-0310-a012-ef5d649a1542

- removed some debugging code from search process - should speed up now
- added some profiling code to search event - more time details in PerformanceSearch_p.html

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4594 6c8d7289-2bf4-0310-a012-ef5d649a1542

changed handling of default values and database paths:
- the default files yacy.init and for the network definition is now moved to the path defaults
- the httpProxy.conf is renamed to yacy.conf
- the DATA/INDEX/PUBLIC is renamed to the actual network nickname, which should be freeworld or sciencenet
more menu entries
- added apfelmaennchens alternative search page to the menu
- added the new thread dump page to the server log menu point as submenu
modifications
- modified the thread dump page: sorting by thread type

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4575 6c8d7289-2bf4-0310-a012-ef5d649a1542

reverted changes to yacy protocol classes: they caused the sciencenet to loose connections
a comparisment with the main release 0.57 had been made: this showed a stable network
This is an emergency operation to ensure availability of the sciencenet network.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4553 6c8d7289-2bf4-0310-a012-ef5d649a1542

- fixed a bug in remote search that prevented that any results had been generated (!)
- added a great number of printStackTrace and new exceptions that shall be used to find the cause
  for a bug in yacy client-server communication which causes the interruption of data transfer
  which then causes the parser bug for the seed strings.
- tried to fix the communication bug on server-side (copy functions)
Be aware that the log may be full of errors and bugs - there should not be more bugs but there is more to see


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4519 6c8d7289-2bf4-0310-a012-ef5d649a1542

more multithreading support:
- 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

added a search history to the new search page
the history distinguishes between different users and identifies them by their ip
a history is only shown to the user who submitted the search

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4510 6c8d7289-2bf4-0310-a012-ef5d649a1542

- enhanced recognition, parsing, management and double-occurrence-handling of image tags
- enhanced text parser (condenser): found and eliminated bad code parts; increase of speed
- added handling of image preview using the image cache from HTCACHE
- some other minor changes

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4507 6c8d7289-2bf4-0310-a012-ef5d649a1542

- fixed some data types in new search stack
- added image domain presentation to image preview
- added new search page to menu
- added automatic re-search when an old search profile is requested and a crawl is ongoing,
  to fetch newly crawled entries

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4501 6c8d7289-2bf4-0310-a012-ef5d649a1542

- added image sorting by image size. This is the default now.
  This is performed using a 3-stage sorting process:
  - sort by relevance, then do snippet-fetch
  - sort snippets by relevance then do image link extraction
  - sort image links by image size; unknown sizes are handled like small sizes
- only the exact amount of images as requested are shown

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4499 6c8d7289-2bf4-0310-a012-ef5d649a1542

- fixed some bugs in ranking computation
- introduced generalized method to organize ranked results (2 new classes)
- added a post-ranking after snippet-fetch (before: only listed) using the new ranking data structures
- fixed some missing data fields in RWI ranking attributes and correct hand-over between data structures

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4498 6c8d7289-2bf4-0310-a012-ef5d649a1542

- changed order of database initialisation (index first)
- removed mainly unused init-time for databases (was only used for tree tables, which are not used any more)


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4496 6c8d7289-2bf4-0310-a012-ef5d649a1542

- performance enhancement for url list parser

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4495 6c8d7289-2bf4-0310-a012-ef5d649a1542

- added new way to watch images from the image search:
  they appear as separate, floating window above the search results,
  not in a new window
- added highslide javascript library for feature mentioned above
- removed dir servlet. This thing was not used as it was supposed to be (as an example applet)
  and was a major problem for intranet-indexing when files are hosted on the same peer.
- added yacy-httpd-internal directory listing. Because YaCy is a search engine,
  directory listings are similar to search result listings. Intranet indexing from the same peer
  will get nice index pages for document collections.
- removed unused test applet

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4494 6c8d7289-2bf4-0310-a012-ef5d649a1542

modified dir servlet to cooperate with intranet indexing from the own HTDOCS repository:
- removed md5 file generation (spoils the won repository)
- removed comments in file share (was never used)
- moved dir list comparator to other place (maybe solves problem, lets see)

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4481 6c8d7289-2bf4-0310-a012-ef5d649a1542

activated new kelondroEcoTable file structure.
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.

- removed write buffer from kelondroCache (was never used because buggy; will now be replaced by new EcoBuffer)
- added new data structure 'eco' for an index file that should use only 50% of write-IO compared to kelondroFlex
The new eco index is not used yet, but already successfully tested with the collectionIndex
The main purpose is to replace the kelondroFlex at every point when enough RAM is available.
Othervise, the kelondroFlex stays as option in case of low memory (which then can even use a file-index)

more cleanup in serverDate
- remove direct accesses to SimpleDateFormat fields in serverDate and use the static parse... methods instead
- remove nowDate() as a Date doesn't store timezone information and a new Date() is always faster

- continued renaming and rearanging (formatter) methods. all should follow the general naming scheme formatWHAT(...)

redesigned remote crawl process:
- 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

redesign of ranking data structure
- the index administration now uses the same code base for url selection and collection
  as the search interface. The index administration is therefore a good test environment for
  ranking order control
- removed old postsorting-algorithms, will be replaced with new one
- fixed many bugs occurred before during ranking; especially the contraint filtering method
  removed too many links
- fixed media search flags; had been attached to too many urls. The effect should be a better
  pre-sorting before media load within snippet fetch

preparations for better ranking: better debugging of index properties
to do this, the index administration interface was extended.
It is now possible to select parts of a index.
See properties shown in interface after a word search for details.


git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4218 6c8d7289-2bf4-0310-a012-ef5d649a1542

enhanced computing speed of kelondro core function: sorting
the enhancement was made by using better organized data structures and
multi-threading during the sort. A sort can be divided into two separate
processes when the first partition of the quicksort algorithm was done.
Generating a separate thread and starting the thread takes only 10 milliseconds,
so using a separate thread makes only sense if the data amount is large.
statistics about the speed-up:
without ehancement: 250 milliseconds for 100000 entries
with data structure enhancement: 170 milliseconds for 100000 entries
with additional second thread (if second processor is present): 130 milliseconds.

For dual-processor systems, this means about 100% speed-up
a test can be made with the following command:
java -classpath classes de.anomic.kelondro.kelondroRowCollection

Allow absolute paths in configuration settings.
- before absolute paths would be expanded incorrectly, e.g.: fooPath=/a/b/c would become /path/to/yacy/root/a/b/c. Now you can put nearly every dynamically generated data with a configurable path to a location outside of yacys root dir without having to use symlinks (probably good for third party distribution packaging).
- abstractServerSwitch.getConfigPath(setting, default) returns a File instance, either with an absolute path or relative to the applications root path.

- exceptions (hardcoded): 
  DATA/LOG/yacy.logging
  DATA/SETTINGS/httpProxy.conf
  DATA/SETTINGS/user.db
TODO: all of these are the global configuration files and they should probably be put into _one_ command line configurable settings path, so it would be possible to package them in /etc/ for example.

- add missing workPath to yacy.init (it was used in code, but there was no default in the file)
- fix broken skinPath (was skinsPath in yacy.init but skinsPath in the code) + a few other broken config reading caused by typos.
- replaced path setting names and their default values with the related static fields in plasmaSwitchboard where not already done/existing

changed behavior of crawl stacker
- 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

preparations for mass remote crawls:
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

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4181 6c8d7289-2bf4-0310-a012-ef5d649a1542

* Complete number localization and provide a more reasonable interface to serverObjects:
- 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.

git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4178 6c8d7289-2bf4-0310-a012-ef5d649a1542

- Changed yFormatter handling to be more flexible and produce more readable code for server pages. There are serverObject.putNum() methods to allow adding of number type values in a formatted form, and put() methods for number types that add them without formatting. This reduces the need to transform them into Strings in server pages and removes the HTML encoding step which is unecessary for numbers.
- some minor code cleanups (mostly unnecessary casts, null checks)

Add a generalized Formatter class yFormatter inspired by http://forum.yacy-websuche.de/viewtopic.php?f=5&t=437
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.

extended client connection clean-up:
there are now two time-outs, one for the complete connection time, and one for an idle time
connections that are idle for more than 2 minutes are closed, and connections that are alive since more than one hour are also closed
if the complete number of connections exceeds 64, all connections more than 64 and have most idle time are also closed

During normal operation of peers these forced closings should never appear,
but the existence of the idle connection check ensures the availability of the peer and the usability of the host.

re-designed some parts of DHT position calculation (effect is the same as before)
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

- redesigned crawl start menu, integrated monitoring pages
- 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.

cleanup of unmaintained and outdated performance methods:
removed object pools in httpc. Object pooling is not recommended,
if the creation of the object is not time-intensive. Object pools are only useful,
if there is much computation necessary to create some basic data that is stored
in the object pool and can be re-used. This does not apply to object pools in YaCy.
Object pooling of client sessions would make sense if they would allow re-use of
living connections to other yacy clients. But every connection is closed after usage
of an object in the client pool, therefore the YaCy server client objects are not such
that hold hardware/network-allocated entities.

try to fix connection problem, possible cause for wrong junior status and non-passive passive peers:
the YaCy client treats disconnections during data transmissions as error and discards all data transmitted so far
this did not happen so far until I removed a delay time at the end of the daemon session which prevented this case.
To fix this problem, disconnections during transmissions are not treated as error now, which means that end-of-transmissions
with sudden disconnections are not a cause for peer diconnections any more. To be nice to non-updated peers, the sleep time
at the end of server sessions is also re-enabled.

joined anomic.net.URL, plasmaURL and url hash computation:
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.
