such an entry cannot be instantiated without allocation of new byte[]; instead
it can re-use memory from other kelondroRow.Entry objects.
during bugfixing also other bugs may have been solved, maybe the INCONSISTENCY problem
could have been solved. One cause can be missing synchronization during bulk storage
when a R/W-path optimization is done. To test this case, the optimization is currently
switched off.
More memory enhancements can be done after this initial change to the allocation scheme.

this shall be used to store a fragment of the index on another physical device,
to split IO load and enhance access speed. The index is splitted in such a way
that the LURLs are stored to the secondary location, and the RWIs to the primary
location. This is especially useful for environments where symbolic links are
not possible and may cause IO access even if there is no write access to the
device which hosts the symbolic link.

- the general NURL-index for all crawl stack types was splitted into separate indexes for these stacks
- the new NURL-index is managed by the crawl balancer
- the crawl balancer does not need an internal index any more, it is replaced by the NURL-index
- the NURL.Entry was generalized and is now a new class plasmaCrawlEntry
- the new class plasmaCrawlEntry replaces also the preNURL.Entry class, and will also replace the switchboardEntry class in the future
- the new class plasmaCrawlEntry is more accurate for date entries (holds milliseconds) and can contain larger 'name' entries (anchor tag names)
- the EURL object was replaced by a new ZURL object, which is a container for the plasmaCrawlEntry and some tracking information
- the EURL index is now filled with ZURL objects
- a new index delegatedURL holds ZURL objects about plasmaCrawlEntry obects to track which url is handed over to other peers
- redesigned handling of plasmaCrawlEntry - handover, because there is no need any more to convert one entry object into another
- found and fixed numerous bugs in the context of crawl state handling
- fixed a serious bug in kelondroCache which caused that entries could not be removed
- fixed some bugs in online interface and adopted monitor output to new entry objects
- adopted yacy protocol to handle new delegatedURL entries
all old crawl queues will disappear after this update!

too large collection arrays are now avoided. By default, the biggest
collection index is 7. larger collections are dumped into a commons
directory, but cannot yet be used. Bevore doing a dump, the collection
is splittet into a part which has only root-references, and stored back
to the collection; the remaining part goes to commons

- permanent cache flush is switched off. The optimized cache flush
works better if it is a large number of collections that is flushed
together
- the flush size can be configured instead the flush divisor. There is
only one size for all flushes
- collection records that shall be removed during collection transition
(jump from one collection file to another) are now not really removed
but only marked in RAM. add-operations to the collection use these
marked collection spaces
- index bulk write operations are now separated for each file of a kelondroFlex

- collections are now hand-over as collection lists to collection index for merge opertations
- collection index lists are separated into 'new' and 'extend' lists

- write operations into index files are sorted by index;
that means that a R/W head does not need to go forward

redesign for better IO performance
enhanced database seek-time by avoiding write operations at distant
positions of a database file. until now, a USEDC counter was written
at the head-section of a kelondroRecords database file (which is the
basic data structure of all kelondro database files) to store the
actual number of records that are contained in the database. Now, this
value is computed from the database file size. This is either done
only once at start-time, or continuously when run in asserts enabled.
The counter is then updated only in RAM, and written at close of the
file. If the close fails, the correct number can be computed from the
file size, and if this is not equal to the stored number it is a strong
evidence that YaCY was not shut down properly.
To preserve consistency, the complete storage-routine had to be re-written.
Another change enhances read of nodes in some cases, where the data-tail
can be read together with the data-head. This saves another IO lookup during
each DB node fetch.
Includes also many small bugfixes.

Such constraints may formulate specific restrictions to web searches
This is implemented by scraping information for constraints from a web
page during parsing, and storing flags to the pages within the web index.
In this first step, only information for index pages ("index of", directory listings)

- crawler now returns an error message if it is used in sync mode (e.g. by snippet fetcher)
*) snippet-fetcher: more verbose error messages
*) serverByteBuffer.java: adding new function append(String,encoding)
*) serverFileUtils.java: adding functions to copy only a given number of bytes between streams
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2641 6c8d7289-2bf4-0310-a012-ef5d649a1542
- new class htmlFilterInputStream.java which allows to pre-analyze the html header to extract
the charset meta data. This is only enabled for the crawler at the moment. Integration into
proxy needs more testing.
- adding eventlisterner interfaces to the htmlscraper to allow other classes to get informed
about detected tags (used by the htmlFilterInputStream.java)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2624 6c8d7289-2bf4-0310-a012-ef5d649a1542
- serverFileUtils.java:
-- adding methods to copy from stream to writer and readers to writers
-- moving httpc writeX methods into serverFileUtils class
- serverCharBuffer.java: removing inheritance from Writer class
- replacing htmlFilterOutputStream by htmlFilterWriter class which handles
content as char stream
- htmlFilterContentTransformer.java: deactivating getText mode
(still needs to be migrated to use char streams instead of byte streams)
- changes in several classes to use htmlFilterWriter instead of htmlFilterOutputStream
- changes in Scraper and Transformer classes to operate on chars instead of bytes
- httpdProxyHandler.java: bugfix. clientTimeout setting was missing in config file

- added new image 'B' in front of search results for bookmark generation
- added news generation when a public bookmark is added
- the '+' in front of search results has new meaning: positive rating for that result
- added news generation when a '+' is hit

*) htmlFilterContentScraper.java: using proper charset for document title
*) serverByteBuffer.java: adding new toString which allows to specify the charset for byte encoding

there are now two full-controlled caches for incoming indexes:
- dhtIn
- dhtOut
during indexing, all indexes that shall not be transported to remote peers
because they belong to the own peer are stored to dhtIn. It is furthermore
ensured that received indexes are not again transmitted to other peers
directly. They may, however be transmitted later if the network grows.

this is a set of search processes that shall enrich search results
with specialized requests to realize a combination of search results
from different peers.

if the new database is switched on, no 'too big' messages appear,
all the WORDS files can be completely migrated

- added generation of a compressed index within remote peers during global search
- added selection of specific urls within remote peers during secondary global search

*) next step of restructuring for new crawlers
> HTCaching should now work protocol independent
-- introduction of new ResourceInfo objects containing protocolspecific metadata
of a resource.
-- the ResourceInfo objects now implement old functions like shallIndexCacheForXXX,
shallStoreCacheForXXX in a protocol dependent manner
> Indexing should also work protocol independent now

*) next step of restructuring for new crawlers
- adding first testversion of ftp crawler class
-- does not create a htCache entry yet
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2483 6c8d7289-2bf4-0310-a012-ef5d649a1542
- IndexCreate_p.java: correcting problems with ftp urls
- URL.java does not cutout the userinfo anymore
(needed to transport authentication info in ftp urls, e.g. ftp://username:pwd@ftp.irgendwas.de)
- plasmaCrawlLoader.java:
-- hack to re enable https urls
-- adding function getSupportedProtocols
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2482 6c8d7289-2bf4-0310-a012-ef5d649a1542
- adding function isSupportedProcotol to plasmaCrawlLoader.java
- disabling robots.txt check for protocols other than http(s)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2479 6c8d7289-2bf4-0310-a012-ef5d649a1542
- adding interface class (plasma/crawler/plasmaCrawlWorker.java) for protocol specific crawl-worker threads
- moving reusable code into abstract crawl-worker class AbstractCrawlWorker.java
- the load method of the worker threads should not be called directly anymore (e.g. by the snippet fetcher)
to crawl a page and wait for the result use function plasmaCrawlLoader.loadSync([...])

- conversion of the crawler pool into a keyed object pool
- crawlers are now loaded based on the url protocol (of course works only for http now)

* replaced kelondroTree for NURLs by kelondroFlex
* replaced kelondroTree for EURLs by kelondroFlex
take care, may be very buggy
please finish crawls before updating. crawls will be lost.

- catchup of OutOfMemoryError in server threads
- automatic adoption of word cache size after a Short Mem Cycle

is corrupted. The cause is, that the deleted-records-chain has wrong entries,
and one of the pointers in that chain points to a place behind the file end.
This causes an IndexOutOfBoundsException within an IO operation.
I currently don't know the reason that the deleted-records-chain is
corrupted, but the error can be catched. If this now happens with the
assortment database, the database is deleted.

* adopted all code to use the declaration form of kelondroRow
* fixed a bug in kelondroRow which caused wrong parsing of encoding type
* the bug caused bad database behaviour in new indexCollection data structure.
because of this bug, all test databases are now already void. A new database is created
* the kelondroFlexTable and indexCollection data structures now store a declaration of the row definition
into a properties file along the database files.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2375 6c8d7289-2bf4-0310-a012-ef5d649a1542
for indexing, the plasmaWordIndex.
The new data structure is ready-to-use, but currently disabled.
It can be activated by setting the static
plasmaWordIndex.useCollectionIndex
to true. This shall be done for testing purpose.
The new index is stored to
DATA/INDEX/PUBLIC/TEXT
The directory PLASMA shall be used only for crawler in the future.
Attention: during testing the data structure in INDEX may change,
and created indexes with the new data structure may get useless.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2348 6c8d7289-2bf4-0310-a012-ef5d649a1542
this is the new database structure that is supposed to replace the
plasmaAssortmentCluster AND the plasmaWordIndexFileCluster
The new structure is not yet active and needs to be integrated into
plasmaWordIndex. This has some migration constraints that are not yet
completely solved.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2347 6c8d7289-2bf4-0310-a012-ef5d649a1542
shall replace the current assortment files.
* used the kelondroFlexTable to hold the index of collections
* used kelondroRow definitions to declare all data structures
* fixed several bugs that appeared in kelondroRowSet and kelondroRowCollection during testing
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2344 6c8d7289-2bf4-0310-a012-ef5d649a1542
* replaced indexTreeMapContainer by indexRowSetContainer
* deleted indexTreeMapContainer and abstract class
This is another step to the new database structure
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2343 6c8d7289-2bf4-0310-a012-ef5d649a1542
to store the index entry. This is another step to move to the new database structure.
A side effect of this change is, that index storage uses much less RAM space,
which affects the index RAM cache.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2341 6c8d7289-2bf4-0310-a012-ef5d649a1542
indexContainers from RAM must be cloned explicitely to prevent
side-effects on stored indexContainer objects in Cache
* changed behaviour of urlReference deletion from indexContainers:
deletion does not user retrieval of all Elements from the assortments
* added textual configuration of kelondroRow and kelondroColumn definition
* update of kelondroRow usage in yacyNews
* modified kelondroAttrSeq to use modified kelondroColumn parser
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2339 6c8d7289-2bf4-0310-a012-ef5d649a1542
an iteration of key elements in kelondroTree databases is no longer supported.
this is now replaced by an iteration of kelondroRow.Entry objects from the database
Iteration of keys from the database was mostly followed by retrieval of the row
from the database, whcih caused unnecessary database load.
The index selection was also redesigned to use the new row iteration methods.
This affects many funktions, most important is the DHT selection routine which is now much faster.

* store() is now called explicitely
* more urls are written to the EURL table
* the EURL stack does not store the complete entry any more, now only the URL hash
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2323 6c8d7289-2bf4-0310-a012-ef5d649a1542
when extracting from eurl, the html output format is recommended, since
this format adds also the fail reason to the domain/url.
The complete syntax for domain extraction is now
java -Xmx<megabytes>m -classpath classes yacy -domlist [ -source { lurl | eurl } ] [ -format { text | zip | gzip | html } ] [ <path to DATA folder> ]

* mainly for the transition to the new indexing database structure
* a bugfix for an endless loop inside kelondroTree iteration
* a bugfix for bulk read inside a kelondroTree iteration; the bug caused that some elements had been iterated twice
* very strong speed enhancement for url/domain extraction

This shall be seen as an experiment to exclude all cases where
there could be a DNS lookup during URL comparisment.
