- current Jetty implementation advances so that it seems not beneficial to keep the code
as it makes the test unuseable and use of Jetty 9 is due to Java 1.7 dependency not in sight.
the class org.apache.pdfbox.pdmodel.font.PDFont occupies 8MB of space
which cannot be cleaned if PDFont.clearResources is called.
The attempt to clean the class cache therefore causes that the class is
loaded and this cache is initialized with some rubbish. I tried to
prevent to instantiate this class by usage of a hacked findLoadedClass
call to the SystemClassLoader (which is protected ...).
Now, without using the PDF parser at all, 8MB of RAM space is not
occupied, however, when the first PDF arrives this space will be taked
and never given back to GC.
WAKE UP YOU LAZY PDFBOX HACKER AND FIX THIS SHIT!
not-flushed Solr cache is now handled in this way:
- it is smaller by default
- an Solr-internal process is started to flush the cache periodically
(this does NOT clean the cache, just removes old objects)
- a Solr-external process (the standard YaCy cleanup-process) now has
direct access to the solr internal cache and flushes them completely.
The time frame for such a flush is defined by the cleanup-process
frequency, by default 10 minutes.
- see numerous idx entries with content_type image without url_file_ext_s (for various reason) which should be included in result
- try it yourself with following sample query
/solr/select?q=content_type:image/* AND -url_file_ext_s:[* TO *]&defType=edismax&fl=sku,url_file_ext_s,content_type
adresses also possible url without or deviating extension.
- use current YaCy version number
- make use of libbuild\GitRevMavenTask (maven-plugin-gitrevisionnumber)
- make yacyBuildProperties.java available for source filtering by Maven-plugin (copy to libbuild\java-templates)
- update assembly definition to include lib\yacycore.jar without version number (needed this way by startupscript)
- it injects properties which can be used in pom via ${DSTAMP} ${releaseNr} if added as plugin via
<plugin>
<groupId>net.yacy</groupId>
<artifactId>maven-plugin-gitrevisionnumber</artifactId>
<version>1.0</version>

the embedded Solr (the default). This was obtained by cirumventing solrj
search encapsulation and the implementation of direct index access
methods to Solr.
The effect will not only be seen during search, but this has also a
strong effect on suggestions (much more) and less CPU power usage during
index distribution (which needs many search requests)
- based on Jetty ProxyServlet
- at this time use existing HTTPD ProxyHandler for url rewrite
- add jetty-client jar (dependency in Jetty ProxyServlet)
reuse ProxyHandler.convertHeaderFromJetty in YaCyDefaultServlet
