on proxied pages a link to exit proxy is added to top of page.
Link text can be configured in web.xml init-parameter (see default/web.xml). If missing no link is displayed.
- use JSoup parser for selective rewrite of html body <a href= links only,
instead of regex which rewrites also header href/src links
- this improves display of pages which use header <base> tag
- tags with src attribute are taken from original location (like css) improving display and are not routed trough the indexer
Disadvantage: scripting links will drop out of proxy
Setting of the servlet through web.xml exclusivly (in case one would like to quickly switch back to the YaCyProxyServlet,
leaving the existing code of YaCyProxyServlet untouched available)
- should be investigated in more detail to look for additional implications
Remove "yacyaction" from proxyservlet as it was only needed for removed interaction routines.
- move htroot exist check from old httpdfilehandler to startup, remove from filehandler and legacy proxyhandler
- use SwitchboardConstant.htroot where appropriate
webgraph. These cores are now accessible at
/solr/collection1/select instead /solr/select?core=collection1
and
/solr/webgraph/select instead /solr/select?core=webgraph
in addition to the old behavior to support compatibility to the old
peers. These new paths are fully solr standard-conform and will allow
the cross-linking between YaCy peers using their public solr API.
- since specific heuristic Twitter & Blekko is not longer available or redundant with OpenSearchHeuristic,
adjusted ConfigHeuristic to use OpensearchHeuristic settings only.
For this the default OSD search target list is made available (copied) by default and the other configs are removed.
- the return of QueryGoal.getOriginalQueryString includes the queryModifier, which are held separately in a modifier object,
but in most (all) cases just the query term is expected, clarified and renamed it to QueryGoal.getQueryString which returns
just the search term (if needed a .getOrigianlQueryString could be implemented in Queryparameters, adding the modifiers)
- started to adjust internal html href references from absolute to relative (currently it is mixed).
For future development we should prefer relative href targets (less trouble with context aware servlets)
request into a separate thread and ignores the furthure result of a
request if that does not answer within the requested time-out. This is a
try to solve a problem with the peer-ping, which hangs whenever a peer
appears to be dead or blocked.
as BASIC were pwd is transmitted near clear text (B64enc).
This has some implication as RFC 2617 requires and recommends a password hash MD5(user:realm:pwd) for DIGEST.
!!! before activating DIGEST you have to reassign all passwords !!! to allow new calculation of the hash
- default authentication is still BASIC
- configuration at this time only manually in (DATA/settings) or defaults/web.xml (<auth-method>
- the realmname is in defaults/yacy.init adminRealm=YaCy-AdminUI
- fyi: the realmname is shown on login screen
- changing the realm name invalidates all passwords - but for security you are encouraged to do so (as localhostadmin)
- implemented to support both, old hashes for BASIC and new hashes for BASIC and DIGEST
- to differentiate old / new hash the in Jetty used hash-prefix "MD5:" is used for new pwd-hashes ( "MD5:hash" )
- taking out customized SecurityHandler code as the original/default seems to just work fine
- with this individual sec. constraints can be applied via web.xml (using legacy role names)
- 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

via Jetty IPAccessHandler to allow only configured IP's to access.
Handler is only loaded if a restriction is configured.
Since IPAcessHandler (Jetty 8) does not support IPv6 system property java.net.preferIPv4Stack=true
Testing showed system.setProperty seems to be sensitive to point of calling (earliest possible time seems to be best = early in yacy.main).
Moved the "isrunning..." just open browser check also to the new routine to preread the yacy.config only once.
hash even if localhost access is disabled. This is urgently needed for
the apicall.sh script since that is used for high-availability set-up
(checkalive and indexdump for index mirroring)
call response with post=0 (if post empty) simulating previous behavior.
(template servlets typically test for post==null,
found one more Crawler.p.java were empty post caused problem,
= defaults not correctly set)
with proxy handler, what is currently
- use switched on in config
- access from a local IP / hostname
fix shutdown exception for crashprotection handler on interrupted connections.
- user entry in UserDB with admin right can login to access protected pages
- dto. admin user, choosen username is stored in conf (adminAccountUserName=)
- userDB is not sync'ed with Jetty credentials as of now only the std. admin account can login
switched initial browser open with ssl active back to std. http port
!!! attention !!! to make sure YaCy can start, https will be disabled if port 8443 is used
- added ping test for above to migration
- as of now port for https is hardcoded to default 8443
- if not urgend required I'd leave it this way (it's standard) to use different ports for http and https
- post https port on ConfigBasic.html (if active)
- 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
- domainhandler causes closed response output stream in following handlers
on addresses resolved to local peer (like in hello protocoll preventing peer to switch to senior peer)
- 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
- adding domain & proxy handler to a context (as it was in inital design)
(context required for dispatcher)
- make handler context and servlet context parallel available
(to allow use of YaCyDefaultServlet to handle legacyServlets)
- set transparent proxy request handled after dispatch.forward to skip further handling for .yacy domain requests
- the implementation is inspired by Jetty's DefaultServlet
- handles static html content and YaCy servlets
- translates between standard servlet request/response and YaCy request/response specification
With the implementation of YaCy-servlets as servlet instead via a jetty handler it's closer to servlet standard and carries less jetty specific dependencies.
