a5d7da68a0 refactoring: removed dependency from switchboard in Balancer/CrawlQueues 2012-04-21 13:47:48 +02:00

9ad1d8dde2 complete redesign of crawl queue monitoring: do not look at a
ready-prepared crawl list but at the stacks of the domains that are
stored for balanced crawling. This affects also the balancer since that
does not need to prepare the pre-selected crawl list for monitoring. As
a effect:
- it is no more possible to see the correct order of next to-be-crawled
links, since that depends on the actual state of the balancer stack the
next time another url is requested for loading
- the balancer works better since the next url can be selected according
to the current situation and not according to a pre-selected order.

b2fe4b7b1a added a handling of appearances of yacy bot entries in robots.txt if this entry addresses the yacy peer
(directly or indirectly) and it grants a crawl-delay of 0. Then all forced pause mechanisms in YaCy are switched off and the domain is crawled at full speed.
crawl delay values can be assigned to either
- all yacy peers using the user-agent yacybot
- a specific peer with peer name <peer-name>.yacy or
- a specific peer with peer hash <peer-hash>.yacyh

22dbbcfa56 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.

1d8d51075c 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.

67aaffc0a2 - 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.
