- to make this possible, a large refactoring and reorganisation of data structures was necessary

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

- 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)

- 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

- 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
- 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.

- 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

- changed build script to use java 1.5 compiler
- first stept to resolve missing generics definition (about 400 from over 4100 'missing'-warnings)

- 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(...)

- workaround for illegal line endings (LF only), closes: http://forum.yacy-websuche.de/viewtopic.php?f=6&t=595
- fixed bug where we didn't break the processing immediately on EOS (the loop was run until the buffer was completely filled with -1)
- further performance improvements (one simple loop, avoid double processing of every byte and unnecessary temporary buffers)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4270 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

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
- 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.

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.

and replaced old fist hash computation by new method that tries to find a gap in the current dht

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.

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.

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

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.

- fixed wrong XML output if no peers are known in Network.xml
- simplified parsing of table properties in wikiCode and ZTableToken
- reimplemented GC heuristics. They are needed to constantly ensure that an amount of free memory is available which is higher than Java's max. limit for performing a Full GC (please use serverMemory.request(long, boolean) rather than serverMemory.available(long, boolean) to provide data for averaging over the last GCs)

- 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!)

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.

- better memory allocation for FlexTable indexes
- splitting between static index and dynamic index (only the dynamic part must grow)

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.

- the speed was doubled by avoiding read access during the dump
- the speed was dramatically increased at least by factor 10
by using a temporary ram-file where the structures are flushed to
