- added the new setting as configurable in the "Debug/Analysis" settings
page. Debug/analysis is its main purpose for now as there is currently
no nice and "understansable" ranking score info servlet (see forum
discussion http://forum.yacy-websuche.de/viewtopic.php?f=8&t=5884 )
- render in the "Search Page Layout" page preview when enabled
- added constants
Revealed by commit c77e43a : the exception was then thrown when indexing
pages containing mailto: scheme URL links with the Solr Webgraph core
enabled.
Fixed the error case and restored filtering on mailto links in
Document.resortLinks() as these URLs still should not appear in
Document.hyperlinks.
On MediaWiki dump imports, the SurrogateReader was trying to unread too
many bytes, then failing with the following exception :
"java.io.IOException: Push back buffer is full".
When using a public HTTP URL in /IndexImportMediawiki_p.html, the remote
file now is directly streamed and processed, allowing import of several
GB dumps even with a low memory remote peer, and without need to
manually download the dump file first.
Detected when importing recent MediaWiki dumps containing some pages
with script content in plain text format (see Scribunto extension
https://www.mediawiki.org/wiki/Extension:Scribunto ).
Further improvement : modify the MediawikiImporter to prevent processing
revisions whose <model> is not wikitext.
Creating a MultiProtocolURL instance from a File object and then
retrieving a File with getFSFile() was inconsistent with file paths

count.
This might be tangential related to http://mantis.tokeek.de/view.php?id=736
as the example includes a local index search, while rwi results are not
counted.
The keywords field string is split into words as navigator entries.
A keyword navigator facet is essential for search appliance usage were
documents and metadata use often specialized keyword vocabularies to
filter search results. This navi can be used without custom index schema.
As we don't have defined a search query command to filter "keywords" yet,
the filtering is limited by adding the keyword to the search query.
warc = Web ARChive File Format.
Warc files with extension .warc or compressed warc.gz can be placed in the
DATA/surrogate/in and contained responses are imported to the index.
The used library is stream based so we can easily extend it later to use
and load warc's from the net.
- enabled HTTP POST calls with Digest HTTP authentication
- made API calls compatible with API newly restricted to HTTP POST only
with transaction token validation
- ensured backward compatibility with older entries recorded as HTTP
GET
- ensure use of HTTP POST method : HTTP GET should only be used for
information retrieval and not to perform server side effect operations
(see HTTP standard https://tools.ietf.org/html/rfc7231#section-4.2.1)
- a transaction token is now required for these administrative form
submissions to ensure the request can not be included in an external
site and performed silently/by mistake by the user browser
When programmatically requesting the local peer with Apache http client,
authentication credentials must be passed as clear-text values.
This extension to the apache org.apache.http.impl.auth.DigestScheme
permits use of the YaCy encoded password stored in the
adminAccountBase64MD5 configuration property.
A port value of -1 will disable this option.
If set to a value greater 0, YaCy listens on this of on the local loopback
address (127.0.0.1) for a shutdown or restart signal.
E.g. connect to http://localhost:8005/shutdown will stop the YaCy server.
http://localhost:8005/restart will restart it.
This option allows to stop YaCy locally independant from the web web
frontend (which might be configured for password protected remote access).

Add test class

following comment "use of properties as header values is discouraged"
in case where (proxy)HTTPClient overwrites values with supplied url.
Use defined request.referer procedure in response class.
HTTP "Referer" header sent by the browser when using YaCy can now be
controlled either with the referrer meta tag as a global policy, or only
for search result links by adding the attribute rel="noreferrer".
To improve privacy with the less possible regressions, the default is
set as meta tag with value "origin-when-cross-origin" : internal YaCy
links behavior is not affected, but when visiting external websites
referrer url is not empty but stripped from query parameters and path.
Older browsers, Safari, MS IE and Edge do not support the referrer meta
tag, so the standard but less flexible noreferrer link type can also be
enabled as an alternative.

Script content is ignored by default, but the text is filtered for html
tags. Modified scraper to skip tag filtering while within a <script>
section (until a closing tag is detected </script>.
Possible side effect, missing </script> end-tag will truncate trailing
content text.
Fix NPE on disabled local SolrIndex, occuring on search moving to the 2nd result page.
The debug purpose only setting to disabeling local SolrIndex (System Admin -> Debug Settings) should long term probably be removed from production code.
These fields are default enabled but with no doubt not strictly
mandatory with the current code base.
As reported by @reger24, splitting between essential mandatory and
optional fields is still to be improved to reflect the current YaCy
needs.
- Added a new method to check activation of mandatory fields on
Collection Configuration commit, consistently with checks previously
performed in Switchboard startup and with mandatory fields in the
default schema.
- Reorganized default schema and CollectionConfiguration enumeration :
moved no more mandatory fields in a specific section, and moved fields
enabled at startup to the mandatory section.
- Marked mandatory fields as required and with stronger font in the
IndexSchema_p.html page

As reported by Palulukas in YaCy forum
(http://forum.yacy-websuche.de/viewtopic.php?f=18&t=5944&sid=dcef5b899ab4aa9b40e3a3d158c13aed#p33454)
the Index Export operation can fails, notably when the Solr index
contains one or more documents with empty (despite required)
"load_date_dt" field.
This fixes the export failure when the situation finally occurs, but
more should be done to harden verifications on minimum required fields.

Add some javadoc, and not needed remove of omitted fields in postprocessing.
As noticed by @reger24, abusive use of OpenSearch systems should be
prevented, especially if allowing to parse and reuse HTML results.
robots.txt file is now checked before requesting an external OpenSearch
system to respect the host exclusions and eventual crawl-delay value.
The check is also performed when trying to add a new OpenSearch URL
template through the /ConfigHeuristics_p.html admin page.
Many OpenSearch systems do not provide results as standard RSS/Atom
feeds but only as HTML.
This modification add some support for custom OpenSearch HTML results
through the use of mapping files (as already done for federated Solr
search) relying on CSS-like selectors to retrieve information from HTML
content.
An example mapping file is provided to map results from the
www.npmjs.com OpenSearch URL.
As discussed in PR #93 with @JeremyRand and @reger24 this new advanced
settings page includes:
- a new setting to control remote Solr responses encoding
- some existing debug settings which could not be set through the admin
user interface
On timeout, closing remote Solr requests is proper than simply using
Thread.interrupt() that is not effective in most cases. Closing does not
ask commit on remote solr, but release http connections resources and is
more likely to end those threads that can else wait indefinitely.
Other related improvements included :
- no more marking remote peer as not available when remote search is
interrupted before timeout by the cleanup job.
- added a short fine log level trace of failing remote solr requests

To assemble the original link url for out-/inboundlinks, icons and pictures
the *_protocol_sxt and *_urlstub_sxt is needed (due to the used data-reduced

to be able to correctly assemble the original link url.
As mentioned in issue #103, control settings over YaCy disk usage
already existed but lacked a user-friendly way to set them.
I added it to the Performance_p.html administration page with a little
refactoring on the "Resource Observer" fieldset for improved
accessibility and HTML standards respect.
Also added the possibility to enable/disable the autoregulation fonction
from this page.
As reported by @tglman on issue #90, when searching images on the local
index only, pages next to the first were always empty. This was a
regression from commit c25e48e969.
This new "documentStructure" parameter can be set to false to only get
hosts accumulated references on a resource and thus prevent scraping the
specified URL and getting citations references.
Also set WebStructureGraph constants as final and updated the Javadoc
with example api call URLs.
As described in mantis 721 (http://mantis.tokeek.de/view.php?id=721)
WatchWebStructure_p.html failed to include in its structure view https
and other protocols and ports than default http.
As described in mantis 720 (http://mantis.tokeek.de/view.php?id=720),
when requesting this API with a domain name instead of a complete URL
only HTTP references on default port were listed.
This ensure consistent implementation of the url host hash generation
and easier usage finding in source code.
Also added a unit test for this function.
