- domainhandler causes closed response output stream in following handlers
on addresses resolved to local peer (like in hello protocoll preventing peer to switch to senior peer)
- introduce a YaCyHttp interface to modulize/separate http server
- adjust the Jetty version specific implementation part (in package net.yacy.http)
- putting the version specific code in classes starting with Jetty8xxxx
- moved existing Jetty9xxx implementation into a test class (to keep the code)
- adjust build to the changed jars
- make use of the introduced YaCyHttpServer interface in related htroot servlets
- adjust other test cases/classes
This shall fulfill the following requirement:
If a document A links to B and B contains a 'canonical C', then the
citation rank computation shall consider that A links to C and B does
not link to C.
To do so, we first must collect all canonical links, find all references
to them, get the anchor list of the documents and patch the citation
reference of these links.
- adding domain & proxy handler to a context (as it was in inital design)
(context required for dispatcher)
- make handler context and servlet context parallel available
(to allow use of YaCyDefaultServlet to handle legacyServlets)
- set transparent proxy request handled after dispatch.forward to skip further handling for .yacy domain requests
are deleted to terminate the crawl because otherwise the crawl will go
on after the load-from-passive stack policy.
- better check if a crawl is terminated using the loader queue.
since httpclient uses the domain-cache it is useful not to clean the
domain cache until crawling is running (domains are filled into this
cache)
On huge crawl-starts (eg. from file) my DNS did not follow the high
rates - so I reduced the rate and give some more time(-out)
webgraph index which is temporary filled with the crawl profile key.
This is used to select a set of documents for post-processing as soon as
a crawl is finished. Now the postprocessing for a specific crawl is
started when that specific crawl is finished and not at the end of all
post-processing steps.
profiles are cleaned. This shall enable a profile-termination-driven
postprocessing. To do this, index writings must carry the profile key
which will be implemented in another (next) step.
is visible whenever a location is available in the search result.
To activate this, the search.navigation property in yacy.conf must be
modified to the new default values.
there for deletion), this fixes a problem for the deletion of old
documents for new crawl starts
- added clickdepth and citation computation for fail documents
- the implementation is inspired by Jetty's DefaultServlet
- handles static html content and YaCy servlets
- translates between standard servlet request/response and YaCy request/response specification
With the implementation of YaCy-servlets as servlet instead via a jetty handler it's closer to servlet standard and carries less jetty specific dependencies.
- replaced load failure logging by information which is stored in Solr
- fixed a bug with crawling of feeds: added must-match pattern
application to feed urls to filter out such urls which shall not be in a
wanted domain
- delegatedURLs, which also used ZURLs are now temporary objects in
memory
for anchor attributes.
- this caused that large portions of the parser code had to be adopted
as well
- added a counter target_order_i for anchor links in webgraph
computation
all unique links! This made it necessary, that a large portion of the
parser and link processing classes must be adopted to carry a different
type of link collection which carry a property attribute which are
attached to web anchors.
- introduction of a new URL class, AnchorURL
- the other url classes, DigestURI and MultiProtocolURI had been renamed
and refactored to fit into a new document package schema, document.id
- cleanup of net.yacy.cora.document package and refactoring
html meta fields to get a correct (or: better) date timestamp. The
http:last-modified mostly does not work because it is set to the current
date from most CMS.
ServerSideIncludes and servlet return values need further work (for working jetty integration)
- TODO: added nasty quickfix to allow SSI - needs further work
- TODO: YaCy servlet return values/parameters are not handled
fuzzy_signature_copycount_i, which count the number of copies of
non-unique documents and assigns this to each document. Thus, each
document there is a number assigned which shows how many copies of this
document exists.
These fields are disabled by default.
like normal documents. Using this option (by default on at this moment;
this might change soon) it is possible to get the exif data into the
search index to be used in image search.
regular expression on th url: the collection attribut for a crawl start
may be now either a token or a list of tokens, seperated by ',' where a
token is either a string or a pair <string,pattern> where the string is
separated to the pattern with a ':' and the string is assigned to the
document as collection only if the pattern matches with the url.
because the double-check error was written to the error-db and never
deleted. No the error-db is cleared on every start and these
double-messages are not written to the error-db any more.
in intranets and the internet can now choose to appear as Googlebot.
This is an essential necessity to be able to compete in the field of
commercial search appliances, since most web pages are these days
optimized only for Google and no other search platform any more. All
commercial search engine providers have a built-in fake-Google User
Agent to be able to get the same search index as Google can do. Without
the resistance against obeying to robots.txt in this case, no
competition is possible any more. YaCy will always obey the robots.txt
when it is used for crawling the web in a peer-to-peer network, but to
establish a Search Appliance (like a Google Search Appliance, GSA) it is
necessary to be able to behave exactly like a Google crawler.
With this change, you will be able to switch the user agent when portal
or intranet mode is selected on per-crawl-start basis. Every crawl start
can have a different user agent.
- use ordered list to use preferred parser for mime/extension first (relates to html, rdfa, argument parser)
- harmonize xhtml extension config for the 3 html base parsers
by checking vocabulary tags also for rwi results (currently a filter is applied to the solr query)
TODO: as vocabularies are only locally valid, auto-switch to Searchdom.LOCAL could be considered.
because it's normal that a boolean value is missing in the post argument
if a checkbox is not selected.
Added also some style enhancements to IndexFederated, removed the Solr
attachment manual and replaced it with a link to the wiki which explains
this in more detail.
note: stream.close is done by caller (Textparser.parseSource)
- removed unnecessary reset in AugmentParser
- added stream.mark in tdfatripleimpl. to make stream.reset work here

of the lazy instantiation rule this value was not actually written, but
if lazy instantiation is switched on, then this causes that all crawl
starts delete all crawl-start-hosts completely because this looks for
filled error reasons.

(like .ps .rdf files and other)
- remove redundant file extension registration
- Rewrote usage of HashMap/Map to concurrent versions (to avoid a
CME=ConcurrentModificationException)
- Rewrote ConnectionInfo (as an example) to use a synchronized iterator
instead of synchronizing an
already synced HashSet (see Collections call)
- This avoids catching CMEs again
- Commented out noisy ConcurrentLog.logException() call
