caused by a JRE bug, the PixelGrabber had to be circumvented using an
own frame buffer which can be read without a PixelGrabber. This resulted
in ultra-fast and much less memory-consuming transformation. YaCy images
are now generated really fast!
- replaced the dot in the NetworkGraph with arrows
- enhanced the image drawing speed using pre-computed color values
- added more attention for OOM cases during very large image painting
main time-consuming process. This shall be done in concurrency.
- added concurrent processes to call the PixelGrabber and framework to
do that (queues)
It is now possible to create 4k-Images (3840x2160) i.e. with the Network
Graphics servlet
compressed deflater output, then assign an exact-sized byte[] which
makes resizing afterwards superfluous
- after all enhancements all class objects were removed; result is just
one short static method
- made objects final where possible
quite a bit to remove all code that handles transparency. With this
highly specialized png writer it is possible to write png images much
faster that with the JRE built-in png writer.
In a second step it can be possible to add concurrency to increase
computation speed further.
- multiple hosts can be listed (comma-separated) as host argument
- new 'bf'-attribut (branch factor): the maximum number of edges per
node
- the bf-value is computed automatically
- ordering of nodes when the graphic is drawed: mostly the drawing ends
with an limitation eg. number of nodes. When this happens, it should be
ensured that more 'interesting' nodes are painted in advance. This is
now done by sorting all nodes by the number of links they have in de
distant sub-graph.
superfluous. The target is to make a solr document as the core of YaCy
documents which would cause that many conversions can be removed. On the
way to this target the Equivalence of URIMetadataRow and URIMetadataNode
had to be removed to expose the usage of the old URIMetadataRow data
structure.
This refactoring already removes unneccessary conversions and should
make memory usage during indexing lower.
which had been then mixed with remote RWIs. Now these Solr documents are
feeded into the result set as they appear during local and remote
search. That makes the search much faster.
table. This may be necessary if the api is called by remote command and
the recordings are not used. Then they can be deleted frequently by
calling this clear command using a cron job
URIMetadataNode which creates the opportunity to access Solr objects
directly and use their information richness
- lazy initialization of the URIMetadataNode object - should cause less
computation and memory usage during search.
- removed dead code
- showing also outbound links to other domains if there are any
- the outbound links browser shows also the link structure image
- showing even inbound links if the web structure graph has information
about that
- removed the left menu and made the HostBrowser a part of the top menu
for search
- moved the file search also to the top menu
- added hover information in the HostBrowser to explain what the click
means
- because the HostBrowser also links to the Metadata viewer ViewFile,
there should be a button to switch back to the HostBrowser: added that
also.
MultiProtocolURI during normalform computation because that should
always be done and also be done during initialization of the
MultiProtocolURI Object. The new normalform method takes only one
argument which should be 'true' unless you know exactly what you are
doing.
