- changed build script to use java 1.5 compiler
- first stept to resolve missing generics definition (about 400 from over 4100 'missing'-warnings)
- added key-iterator to kelondro databases (for rapid from-memory enumerations, will be used for domain name collection, not used yet)
please set your development environment to use java 1.5!

a new release type was added: 'embedded' which is the same as the current standard release was
this will not have any effect to the next release 0.56, which will still a pro-release on public download

- 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
- default formatter methods use a GMT timezone by default now, this is important for interchangability as some date formats we use don't include a timezone offset.
- continued renaming and rearanging (formatter) methods. all should follow the general naming scheme formatWHAT(...)

- instead of pushing urls to other peers, the urls are actively pulled
by the peer that wants to do a remote crawl
- the remote crawl push process had been removed
- a process that adds urls from remote peers had been added
- the server-side interface for providing 'limit'-urls exists since 0.55 and works with this version
- the list-interface had been removed
- servlets using the list-interface had been removed (this implementation did not properly manage double-check)
- changes in configuration file to support new pull-process
- fixed a bug in crawl balancer (status was not saved/closed properly)
- the yacy/urls-protocol was extended to support different networks/clusters
- many interface-adoptions to new stack counters
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4232 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4223 6c8d7289-2bf4-0310-a012-ef5d649a1542
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.

- enhanced searchtime in kelondroRowSets
- enhanced uniq() - reverse enumeration causes less time in case of mass removal of doubles
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4207 6c8d7289-2bf4-0310-a012-ef5d649a1542
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
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4198 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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

- Test wCacheMaxChunk against maxURLinCache(), not getMaxWordCount(). This triggered a flush everytime dhtFlushControl() was called.
- If triggered, flush at least 1 entry.

- final flush only when tabletype = RAM
- prestacker (dns prefetch) only if tabletype = RAM and busytime <= 100
- number of maximun entries in stacker is configurable in yacy.init (stacker.slots)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4186 6c8d7289-2bf4-0310-a012-ef5d649a1542
two main changes must be implemented to enable mass remote crawls:
- shift control of robots.txt to crawl queue (away from stacker). This is necessary since remote
crawls can contain unchecked urls. Each peer must check the robots to prevent that it is misused
as crawl agent for unwanted file retrieval
- implement new index files that control double-check of remotely crawled urls
After removal of robots.txt checking from stacker threads, the multi-threading of this process is void.
Multithreading has been removed. Also the thread pools for the crawl threads had been removed, since
creation of these threads is not resource-consuming, for a detailed explanation see svn 4106
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4181 6c8d7289-2bf4-0310-a012-ef5d649a1542
- update PDFBox package to current version 0.7.3
- use new security model in PDFBox to "guess" wether we can decrypt a document or not
NOTE: When upgrading to this version make sure the old PDFBox-0.7.2.jar is removed from libx/

It seems improbable, but it might happen, that during a crawl all queues (indexing, crawling, ...) except the crawl URL stacker ran empty. This commit adds an additional check for an empty crawl stacker queue before executing the profile cleaner.

in extreme situations this will cause that no remote crawls are send out any more
this is bad, but it protects the case where failing remote crawls fill up the local queue too much,
which is even worse
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4141 6c8d7289-2bf4-0310-a012-ef5d649a1542

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

there is no waiting until the local search terminates to show the result page.
the local search appear like all other results from remote peers using a separated thread.
This has especially a stron effect, if the local index for a specific word is large.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4114 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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.

- added a file size limitation, that disallows parsing of large documents during (offline-) remote search
- added profiling information to search result computation, visible at search access tracker. this info shows used time for URL fetch and snippet computation

1. avoid adding duplicate file name entries in config properties for lists,
2. correctly merge all path masks from all list files for the same host masks,
3. rewrite helper methods standard java methods for Collection transformations,
4. merged various methods with identical functionality for different Collection implementations into one,
5. minor refactoring to improve code readability.

- fixed search tipps (topwords, now appearing at the bottom of the page)
- added search consequences execution (deletion of bad referenced some time after the search happened)
- added some formatting at network table
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4078 6c8d7289-2bf4-0310-a012-ef5d649a1542
search profiling showed, that a major amount of time is wasted by computing url hashes. The computation does an intranet-check, which needs a DNS lookup. This caused that each urlhash computation needed 100-200 milliseconds, which caused remote searches to delay at least 1 second more that necessary. The solution to this problem is to attach a URL hash to the URL data structure, because that means that the url hash value can be filled after retrieval of the URL from the database. The redesign of the url/urlhash management caused a major redesign of many parts of the software. Since some parts had been decided to be given up they had been removed during this change to avoid unnecessary maintenance of unused code.

- snippets are not fetched by browser using ajax, they are now fetched internally
- YaCy-internat threads control existence of snippets and sort out bad results
- search results are prepared using SSI includes
- the search result page is visible right after the search request, the results drop in when they are detected
- no more time-out strategy during search processes, results are shifted within queues when they arrive from remote peers
- added result page switching! after the first 10 results, the next page can be retrieved
- number of remote results is updated online on the result page as they drop in
- removed old snippet servelet (which had been also a security leak btw)
- media search is broken now, will be redesigned and fixed in another step
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4071 6c8d7289-2bf4-0310-a012-ef5d649a1542

some urls are fetched so the url cache can be filled with these urls
- the url-prefetch is used to sort out some unresolved urls
- the snippet-fetcher is triggered with the search event id. This is used
to remove missing snippets from the search cache so they will not be displayed again
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4060 6c8d7289-2bf4-0310-a012-ef5d649a1542
it is necessary for the new search process that will do automatic re-searches
a positive effect is, that when a re-search is done it can be monitored how many
results had been contributed from other peers. The message for this contribution
was moved from the end of the result page to the top.
* enhanced re-search time when a global search was done an the local index has
already a great number of results for this word
* re-organised presearch computation; must be further enhanced

collection objects has been reduced to 50%:
- set new memory calculation functions for indexing process
- adjusted guessed memory amount
-> Testing needed:
try new recommended value (see performanceQueues) and see if OOMs occur.
-> report maximum recommended value, so we can set new default values.

- re-designed remote request result processing
- re-designed local result accumulation, will be further enhanced with snippet fetcher
- removed search process handling in switchboad
- made snippet class static (there is no need for multiple snippet objects)
- removed some redundant tasks in server-side search process, should be a little bit faster now

- refactoring of kelondroRecords; this class is now divided into
kelondroAbstractRecords, kelondroRecords, kelondroCachedRecords, kelondroHandle and kelondroNode
- better abstraction of kelondroNodes, such nodes may now be crated by different classes
- a new Node defining class kelondroEcoRecords defines Nodes that do not need so much allocation and System.arraycopy
- there is less memory transfer on the bus, especially for collection index
- now half of memory needed for web index access

target servers had been able to see search words from the referrer of the favicon fetch.
This has been removed by using the getImage - servlet for favicon fetch.
Since java does not support loading of bmp and ico-Images, such parsers had been added.
The image parser had been coded from their original microsoft documentation.
This influences also the image-search functionality: there can now be a preview
of found bmp-images. Another benefit: favicons for search results are now cached with the HTCACHE.

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

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

- new cluster functions will be available in this menu, but currently not enabled,
because corresponding interface methods are not ready yet
- shifted remote crawl settings to new network configuration menu
- shifted DHT distribution/receive to the new network configuration menu
- adopted some string constants
- added cluster configuration settings to yacy.init

This is a serious problem that is caused by the database bug between 0.511 - 0.513
which produced a large number of double-entries in the RWI index. The uniq()-method
tries to fix this, and it does not terminate when the index is large and the number
of double-occurrences is also large. This patch does simply implement a time-controlled
termination, which does not heal the inconsistency problem. The uniq-method itself
is correct and does not need a bugfix, the non-termination is simply caused by the large number
of data that is shifted during the process. It was possible to reproduce this behaviour
in a test environment.
A real fix would need to:
- enhance the uniq()-method by using a recursive, binary segmentation of the array to be fixed
- uniq() must report the entries that are double
- the double-entries must be deleted from the collection index (from the index and the collections) to heal the problem

- some bugs may have been fixed with wrong removal operations
- removed temporary storage of remove-positions and replaced by direct deletions
- changed synchronization
- added many assets
- modified dbtest to also test remove during threaded stresstest

* removed divide by zero bug when 20_dhtdistribution_busysleep is 0
* replaced German comment with wrong charset in source/de/anomic/plasma/plasmaCrawlBalancer.java by an English one
* replaced the table-fix for floating behind snipped images by a br with clear
* removed unnecessary old xhtml-files (were not in use, they were created when we weren't having xhtml for testing)
* new layout for image-search results: replaced the old one with spans and tables inside (not valid) with new divs, now each image snippet container has the same size
TODO:
* the ids of the snippetLoading-divs aren't valid because ids must start with an alphabetic letter or an underscore, they have to be prefixed
* in the returned snippet-xml is an unresolved pattern for status (the status is only set for text snippets)

- basic protection against start-up problems when database files are corrupted
- auto-delete of not-critical databases during startup when load error occurs
- on-the-fly reset option for all database tables
- automatic on-the-fly reset for seed tables during enumeration exceptions

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 new collection index will be more generalized to support other indexes
i.e. YBR block-rank computation. A clean-up of the many conditions to support
the old database was necessary.
