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.
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)
- transformed log lines to String before they are stored because the
storage space is about 1:250 (45kb for one line before transformation,
180 bytes afterwards)
- this saves up to 10MB RAM so we can increase the number of lines to
1000 again.
which had a problem because of badly used concurrency.
This fix also caused a redesign of the whole host deletion process.
This should fix bug http://bugs.yacy.net/view.php?id=250
the right content domain (i.e. identifying that it is an image, text
etc.) because it used the file extension and not an existing mime type
assignment.
- fixed the new setting that images shall be loaded for a better image
search.
- both fixes together makes it now possible to crawl
commons.wikimedia.org which makes use of 'funny' document names (i.e.
ending with .jpg while the document is html)
the 'API' icon which was the link for the opensearch result which is an
extension of RSS. Since it is more appropriate to visualize a RSS link
with an RSS icon, this API icon was changed here.
- rewrite the description of the options "Restrict to start domain(s)"
and "Restrict to sub-path(s)" to an explanation, that the restriction
applies to all links in the link list of the option "From Link-List of
URL" if this option is selected
- allow "Restrict to sub-path(s)" if the "From Link-List of URL" is
selected. This is supported in the crawl start.
may have contained multiple same expressions within the disjunction of
domain-restrictions. This fix removes the redundant restrictions and
makes the regex shorter.
