be transcoded into jpg for image previews. To create such pdfs you must
do:
Add wkhtmltopdf and imagemagick to your OS, which you can do:
On a Mac download wkhtmltox-0.12.1_osx-cocoa-x86-64.pkg from
http://wkhtmltopdf.org/downloads.html and downloadh
ttp://cactuslab.com/imagemagick/assets/ImageMagick-6.8.9-9.pkg.zip
In Debian do "apt-get install wkhtmltopdf imagemagick"
Then check in /Settings_p.html?page=ProxyAccess: "Transparent Proxy" and
"Always Fresh" - this is used by wkhtmltopdf to fetch web pages using
the YaCy proxy. Using "Always Fresh" it is possible to get all pages
from the proxy cache.
Finally, you will see a new option when starting an expert web crawl.
You can set a maximum depth for crawling which should cause a pdf
generation. The resulting pdfs are then available in
DATA/HTCACHE/SNAPSHOTS/<host>.<port>/<depth>/<shard>/<urlhash>.<date>.pdf
concurrently. When a RWI search result is flushed into the result set,
id does Solr Queries (which replaced the old-style Metadata Queries) and
they are possibly running concurrently to a previously startet Solr
search. Both methods may block each other with IO. To enhance the speed,
they are now serialized. Because the Solr search results may result in
better results using the more advanced and configurable Ranking methods,
this result is preverred over the RWI search result. However, remote RWI
search results are still feeded concurrently into the search result as
well.
if file in DATA/SETTINGS it is loaded otherwise file in ./defaults is loaded
(if locale ./defaults/stopwords.xx doesn't exist take solr/lang/stopwords_xx.txt as default)
move yacy.stopwords, yacy.stopwords.de and yacy.badwords.example out of root directory to ./defaults directory
to always get fresh lists of documents. This is necessary since the
postprocessing changes the same documents which the
postprocessing-collection query selects.
hold a date for each URL to record when a url was first seen. This is
then used to overwrite the modification date for urls upon recrawl in
case that the first-seen date is before the latest document date. This
behaviour is necessary due to the common behaviour of content management
systems which attach always the current date to all documents. Using the
firstSeen database it is possible to approximate a real first document
creation date in case that the crawler starts frequently for the same
domain. As a result the search results ordered by date have a much
better quality and the usage of YaCy as search agent for latest news has
a better quality.
postprocessing the solr documents are now not completely retrieved.
instead, only fiels, needed for the postprocessing are extracted. When
Solr document are written, this is done using partial updates.
This increases postprocessing speed by about 50% for embedded Solr
configurations. For external Solr configurations the enhancement should
be much higher because the postprocessing with remote Solr is very slow.
When doing partial updates to a remote Solr, this method should perform
much better than before, it is expected that this is even much higher
than the increase with local Solr.
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.
*) will try other ports if YaCy standard ports are not available
*) distinguish between internal and external port (not sure if this
works 100%)
Still to add: propery in config to enter own external port (in case of
manually configured NAT)
(this eventually can benefit image search by using mime only)
reduce redundant field assignment for Solrdocuments created from URIMetadataNode (URIMetadataNode = SolrDocument with partially assigned fields)
removed preferred IPv4 in start options and added a new field IP6 in
peer seeds which will contain one or more IPv6 addresses. Now every peer
has one or more IP addresses assigned, even several IPv6 addresses are
possible. The peer-ping process must check all given and possible IP
addresses for a backping and return the one IP which was successful when
pinging the peer. The ping-ing peer must be able to recognize which of
the given IPs are available for outside access of the peer and store
this accordingly. If only one IPv6 address is available and no IPv4,
then the IPv6 is stored in the old IP field of the seed DNA.
Many methods in Seed.java are now marked as @deprecated because they had
been used for a single IP only. There is still a large construction site
left in YaCy now where all these deprecated methods must be replaced
with new method calls. The 'extra'-IPs, used by cluster assignment had
been removed since that can be replaced with IPv6 usage in p2p clusters.
All clusters must now use IPv6 if they want an intranet-routing.
solr to the YaCy built-in solr search servlet. Its not complete and not
fully correct (there is still a utf8 encoding problem) but it is a way
to get easily requests forwarded through YaCy to an external Solr.
it is now possible to get the results in two steps:
- first retrieve all IDs as given for a query
- then retieve each document individually
This was necessary for very large result sets where a query may run for
hours and is possibly terminated by a solr-internal timeout. This occurs
regulary during postprocessing and therefore this commit may fix
unwanted postprocessing terminations.
hour. The table can be shown with
http://localhost:8090/Tables_p.html?table=stats
The entries have the following meaning:
aM: activeLastMonth
aW: activeLastWeek
aD: activeLastDay
aH: activeLastHour
cC: countConnected (Active Senior)
cD: countDisconnected (Passive Senior)
cP: countPotential (Junior)
cR: count of the RWI entries
cI: size of the index (number of documents)
The entry keys are abbreviated to reduce the space in the table as the
name is written again for every row.
This is the beginning of a 'yacystats' micro-alternative als built-in
function in YaCy. Graphics may follow after some time if enough test
data is available.
found a situation after crash (reboot) with existing running semaphore but YaCy not running.
Ping generated exception which finally deleted the conf file (during pre-read procedure)
- change to ping (catch exception solved it)
- additionally removed delete yacy.conf file (if needed we need to make a backup)
during document parsing; instead use the same references that would also
be written into the webgraph. That should cause that the webgraph and
the citation index express the exact same semantic.
attributes are attached to artificial constructed index.html files which
list directories. Such files are naturally rejected by the crawler and
should not appear in the error log because these files are part of the
construction of file crawlers and confuse users if they see them in the
error log.

formulated as edismax query but this was not set as query attribut. The
defType=edismax property needs a qf-field, so this was added as well. Do
not remove that field again! This fixes also a problem with title-unique
computation.
