Also ensure authentication is not lost by Digest timeout when navigating
between index.html and search results page.
This way, running searches with extended features on a remote peer or a
password protected peer works with a regular user (with "Extended
search" rights).
When authenticating on the search page with a user without "Extended
search" rights, it appears as authenticated, but has just its usual
access to the public search features.
Previously rendered as a broken URL containing the absolute file path of
a snapshot on the search server.
Now rendered as a valid URL linking to the /api/snapshot API to provide
available snapshot content. Snapshot format is selected among the
available ones in the following order of preference : JPG/PNG, PDF, and
XML.
The SearchEvent listen to changes on each of its navigators, and the
information about their overall state is sent with each fetched search
item (as a "data-nav-generation" attribute). Then the browser can
regularly fetch a fresh version of yacysearchtrailer.html only if
necessary (when that nav-generation value change).
When the limit is reached, a button allow expanding/collapsing remaining
tags.
When this feature is activated without a limit to the number of
displayed tags, when encountering search results with a very large
number of keywords, the results page can become almost unusable (very
long vertical scrollbar)
This is a fix for mantis 766 ( http://mantis.tokeek.de/view.php?id=766 )
Since the upgrade to Digest authentication, access to protected search
features was indeed disabled once the Digest nonce timed out.
After Digest auth timeout the browser no more sent authentication
information and as the search results page is not private, protected
features were simply be hidden without asking browser again for
authentication.
Adding a supplementary parameter when accessing the search results as
authenticated fixes this.
If swichted on link (click) to the tag adds the keyword to the search query.
If a keyword navigator is active the selected keyword adds or replaces
a query keyword: modifier (currently replace was choosen as multiple
keywords are not fully supported yet)
Using unfiltered detailed counts (local and remote entries found before
doubles detection and before applying query modifiers) was confusing and
inconsistent with the total count. It could let think more results are
to come in the next pages, without understanding why they are not
displayed.
This enables keyword navigator to filter on keywords. Added search page
output and layout config for keywords, allowing e.g. in Intranet use
to display the keywords. No styling or links applied to the keyword
text (but is desirable possibly in combination with bootstrap-tagsinput
for future/intranet).
Added as an additional icon with title in the search progress bar, to
inform about background search feeder threads terminated or still
running. While giving a bit more information to users about the p2p
search process, this can help choosing whether or not wait a little bit
more time before going to the next page, in order to get results from
various sources sorted as best as possible (see #91 for a discussion
about sorting accuracy and network latency).
Other related modifications included :
- regular updates to statistics in the progress bar until the
background feeders are completely terminated.
- removed some uses of unsecure and discouraged JavaScript elements
- 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
This is a fix for mantis 715 (http://mantis.tokeek.de/view.php?id=715).
A possible path scenario that could leading to this case :
- YaCy is running low in memory
- a search is requested
- before the end of search results rendering, the cleanup job runs and
deletes the running search event from the cache because of short memory
- then yacysearchitem renders with "-UNRESOLVED_PATTERN-" parameter
values passed to the statistics() JavaScript function
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.
User-friendly settings page to be implemented.
The augmented Browsing option was reduced to the web proxy functionallity.
Augmented browsing is not available and no known plan exist to reimplement
alteration of result pages with additional information.
Favicon display only makes sense for http(s) websites, being public or
intranet. So I modified the favicon conditional display to verify the
result URL protocol rather than if we are in intranet mode.
Also prevented rendering an img HTML tag with empty src on other results
protocols such as ftp or file.
Fixing this thanks to priest2 report
(http://forum.yacy-websuche.de/viewtopic.php?f=23&t=5923).
This error occurs on /ConfigSearchPage_p.html and on search results page
when Metadata links are enabled.
The fix was to remove unnecessary use of hs.htmlExpand() which is now
part of highslide-full.js library file, currently not distributed with
YaCy (only includes highslide.js). The Metadata links work correctly and
the initial dynamic expansion offered by htmlExpand() did not bring much
usability.
! until better solution is found !.
Reason: in IE-Browser no individual favicon is displayed with <object> tag
(always the default) and only few individual fav's with Firefox (randomly)
hint: to be able to use <img src=ViewImage/> return of default icon was
added back to it.
relates to http://mantis.tokeek.de/view.php?id=629
- moved default favicon processing from ViewImage to
yacysearchitem.html : when previewing ico image search results we don't
want a default favicon be displayed
- throw an IOException ending in a HTTP 500 error when image processing
fails, rather than returning a null result : behavior is more consistent
accross browsers (for exempla Chrome and Firefox), especially with new
default favicon display system
- if an eventDate is given in the search result, replace the document
date with the event date and prefix it with the string "on ".
- the document date is omitted if a date from the cent is shown
Added also the date as fields in the json and rss result sets.
generated dynamically which will stay static in the future. This applies
mainly to the search result favicon in front of search hits. These icons
will now be generated once, but then caches in the browser. There is
also a YaCy-internal cache for these icons which had prevented the
re-generation of the icons in YaCy, but this cache is now superfluous
since the browser should not call the servlet ViewImage again.
used parameter &cat=image is obsolete and returns no results
- remove &cat=image and &cat=href references
- remove &tenant= references (unused)
Use contentdom=image and inurl: parameter to make showPicture link display something (open in new window because of used inurl modifier changes original query)
explored for citations within other documents. A click on the
'Citations' link shows an analysis with all text lines in the document
each with a complete list of documents which contain the same line. A
second section shows the linking documents in ascending order of number
of citations from the original document. Because documents from
different hosts are most interesting here, they are listed at the top of
the page as possible 'copypasta' source.
output writer. This made the creation of a html result writer necessary
which is included in this commit. The yacydoc servlet was used to
present all metadata to a document, but the solr interface can serve for
this purpose in a much better way. All usages (instead one) of yacydoc
were replaced by a solr call. This affects also the 'metadata' link
attached to search results.
- ConfigPortal: added checkbox Host Browser
- yacy.init: added search.result.show.hostbrowser as default = on (true)
- fix HostBrowser: broken link to protected WebStructurePicture for public user
