- 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
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.
This will prevent mistakenly hiding a div element not designed to be an
infobox but having a ".info" parent (After having previously added the
possibility for a div - and not only a span element - to be an infobox).
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.
Fixes second part of mantis 708
(http://mantis.tokeek.de/view.php?id=708)
The bootstrap-switch component has some sizing issues with long labels,
which are not likely to be solved soon due to a lack of resources on
that project (see issue
https://github.com/nostalgiaz/bootstrap-switch/issues/419 )
This fix works by applying the following ideas :
- labels are long, so font-size and padding are reduced on small screen
sizes using a media query
- use relative percent width values on the component wrappers to
prevent overlapping on the neighbour content
- disable animation because it relies on absolute pixels width values
- using a icon-only admin button at small and medium screen size
- using a icon-only "Search Interfaces" button at small screen size
- hiding the YaCy brand at extra-small screen size
Fixes the header part of mantis 708
(http://mantis.tokeek.de/view.php?id=708).
Navigator button overlapping is still to fix.
Upgraded the following JavaScript libraries dependencies :
- bootstrap-switch to 3.3.2
- html5shiv to 3.7.3 and switched to minified version
- typeahead to 0.10.5
- jQuery to 1.12.4
Removed unused bootstratp-rtl.css and bootstrap-rtl.min.css.
Tested non regressions on the following systems :
- Debian Jessie :
- Firefox 45.4.0
- MS Windows 10 :
- Chrome 54.0.2840.99
- Firefox 50.0
- Edge
- Emulated IE 11, 10 and 9
This file is used by Bootstrap documentation website
(http://getbootstrap.com/) but is not part of the Bootstrap distribution
and has not be included in a Bootstrap based application.
- 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
When the sidebar on search page becomes scrollable, the scrollbar shrinks the sidebar and makes the search results weirdly scrollable on X axis by several pixels. Now the sidebar always have a scrollbar, and results are never X-scrollable.
servlet and moved it to a new /IndexExport_p.html servlet. This servlet
is now more prominent linked in the main menu under Production -> Index
Export/Import
- date navigation
The date is taken from the CONTENT of the documents / web pages, NOT
from a date submitted in the context of metadata (i.e. http header or
html head form). This makes it possible to search for documents in the
future, i.e. when documents contain event descriptions for future
events.
The date is written to an index field which is now enabled by default.
All documents are scanned for contained date mentions.
To visualize the dates for a specific search results, a histogram
showing the number of documents for each day is displayed. To render
these histograms the morris.js library is used. Morris.js requires also
raphael.js which is now also integrated in YaCy.
The histogram is now also displayed in the index browser by default.
To select a specific range from a search result, the following modifiers
had been introduced:
from:<date>
to:<date>
These modifiers can be used separately (i.e. only 'from' or only 'to')
to describe an open interval or combined to have a closed interval. Both
dates are inclusive. To select a specific single date only, use the
'to:' - modifier.
The histogram shows blue and green lines; the green lines denot weekend
days (saturday and sunday).
Clicking on bars in the histogram has the following reaction:
1st click: add a from:<date> modifier for the date of the bar
2nd click: add a to:<date> modifier for the date of the bar
3rd click: remove from and date modifier and set a on:<date> for the bar
When the on:<date> modifier is used, the histogram shows an unlimited
time period. This makes it possible to click again (4th click) which is
then interpreted as a 1st click again (sets a from modifier).
The display feature is NOT switched on by default; to switch it on use
the /ConfigSearchPage_p.html servlet.
This is the first element of a new 'decoration' component which may hold
switches for different external appearance parameters.
The first switch in that context is decoration.audio (as usual in
yacy.init). This value is set to false by default, that means the audio
feedback element is switched off by default. To switch it on, set
decoration.audio = true (using /ConfigProperties_p.html). You will then
hear sounds for the following events:
- remote searches
- incoming dht transmissions
- new documents from the crawler
Sound clips are stored in htroot/env/soundclips/ which is done so
because a future implementation will read these files using the http
client and with configurable urls which will make it very easy for the
user to replace the given sounds with own sounds.
not point to youtube directly to prevent that the referer to the peer
address is given to youtube. Instead, a forwarder address at yacy.net is
used to redirect to the tutorial repository (and can be changed later).
- remove verify=cacheonly from admin screen search box to use the configured values
(otherwise definition overwrites configured behavior and is used for following searches what might give unexpected/confusing different results compared to using /yacysearch )
advanced settings to a top-menu entry. Moved the advanced setting to a
less prominent place of the submenu. Removed the table administration
from target analysis submenu because it appeared double, the table
administration is now the default in the system administration.
Sorry for inconvenience if i constantly move menues around, but this
makes just more sense and YaCy is still not finished :)
- added a servlet api/linkstructure.json which generates a link graph
information in json
- added a javascript link graph renderer hypertree.js using d3 and the
new servlet linkstructure.json
- embedded the new link graph in the crawler monitor and the host
browser
