This is a very complex migration: many classes had been renamed or
removed, dependencies changed and the solr index type is now aligned to
be a solr cloud repository.
Together with the Solr 5.2 library update, one other dependent library
had been updated as well: httpclient 4.4->4.4.1
Older indexes are migrated from 4_10 to 5_2. However, the new index
structure is more efficient and we recommend to re-index everything.
Please use the index export before you do the update to a large
surrogate xml file. After the update, start with an empty index and then
initialize this with your dump.
work now, at least it does on my network. UPNP code in YaCy can still
be improved though (see TODO comment: make port on gateway configurable
or find free one).
*) removed old code
*) added new lib
*) changed code to work with new lib
besides adjustments in code it makes the servlet settings in web.xml significant.
This applies to solr, gsa and proxy servlet. There is no longer a default setup in code during init (as jetty 9 checks for double definition).
introduced, it was also used for search facets. The generic search
facets are now deduced from generic solr fields which makes jena as tool
for facet semantics superfluous.
solrj.4.6.0 has a bug which prevents the attachment of a remote solr (as
tested with a SolrCloud). See bug report
https://issues.apache.org/jira/browse/SOLR-5532
This bug shall be fixed in Solr 4.6.1.
Fortunately, solrj-4.5.1 works together with solr-4.6.0 thus the current
index does not need to be changed.
- this allows additional features, like servlet configuration via web.xml and many more things.
- currently the standard servlets are still configured in the code (so the supplied defaults/web.xml is not realy needed, yet),
but could be expanded
- lookup for web.xml - 1. in /DATA/SETTINGS then in /defaults
- 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
- introduce a YaCyHttp interface to modulize/separate http server
- adjust the Jetty version specific implementation part (in package net.yacy.http)
- putting the version specific code in classes starting with Jetty8xxxx
- moved existing Jetty9xxx implementation into a test class (to keep the code)
- adjust build to the changed jars
- make use of the introduced YaCyHttpServer interface in related htroot servlets
- adjust other test cases/classes
ServerSideIncludes and servlet return values need further work (for working jetty integration)
- TODO: added nasty quickfix to allow SSI - needs further work
- TODO: YaCy servlet return values/parameters are not handled
- removed httpclient 3.1 which has been used by solrj < 4.x.x and is now
not used any more
- fixed some parts in YaCy which used methods from httpclient 3.1
