*) Adding first version of db test for mysql
NOTES:
- db user + db + db table must be created before starting the test
- db table must be empty. Entries can not be updated at the moment
- db connection properties must be changed in the sourcecode at the moment
TODOs:
- accepting connection properties via command line
- implementing update + remove + read operations
- 'maybe' adding code to create db + table if it doesn't exists
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@991 6c8d7289-2bf4-0310-a012-ef5d649a1542
to disallow yacy to index the response that belongs to the request where
X-YACY-Index-Contro is set to "no-index"
*) Bugfix for Seed-List download via Remote Proxy.
Now the pragma and cache-control http headers of the request are properly set to "no-cache"
See: http://www.yacy-forum.de/viewtopic.php?p=11639#11639
*) Bugfix for http-Proxy
yacy has ignored "no-cache"- pragma and cache-control http headers that were send in requests.
Now, these request headers are evaluated properly
TODO: Missing evaluation of "no-store" request headers
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@971 6c8d7289-2bf4-0310-a012-ef5d649a1542
- remote proxy configuration can now be "really" changed on the fly and takes effect immediately
- adding possibility to disable remote proxy usage for yacy->yacy communication
- adding possibility to disable remote proxy usage for ssl
- restructuring proxy configuration so that it is stored in a single place now
*) Adding possibility to import a foreign word DB (or even more of them in parallel)
at runtime into the peers DB
- this can be done by calling IndexImport_p.html
- ATTENTION: please not that at the moment this thread must be aborted via gui
before a normal server shutdown is done.
- TODO: integrating IndexImport Thread into normal server shutdown
- TODO: Adding posibility to import crawl-queues, etc. from foreign peers
- TODO: removing old import function from yacy.java and calling the new routines instead
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@968 6c8d7289-2bf4-0310-a012-ef5d649a1542
- adding automatic refresh
- accepts new parameter nameLookup which can be used to deactivate
yacy-peer name lookup (because we have problems with this on large seed-dbs)
*) ViewFile
New page that can be used to view
- original content
- plain text content
- parsed content
- parsed sentences
of a webpage specified by there url hash
Mainly for debugging purpose at the moment
*) Robots.txt
Bugfix for if-modified-since usage
TODO: synchronization of downloads to avoid loading the same robots-file
multiple times in parallel by different threads
*) Shutdown
Better abortion of transferRWI and transferURL sessions on server shutdown
*) Status Page
Adding icon to start/stop crawling via status page
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@950 6c8d7289-2bf4-0310-a012-ef5d649a1542
adding more verbose logging output for db initialization
*) httpdFileHandler.java
adding cache for servlet response methods
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@897 6c8d7289-2bf4-0310-a012-ef5d649a1542
various checks like the blacklist check or the robots.txt disallow check are now
done by a separate thread to unburden the indexer thread(s)
TODO: maybe we have to introduce a threadpool here if it turn out that this single
thread is a bottleneck because of the time consuming robots.txt downloads
*) improved index transfer
The index selection and transmission is done in parallel now to improve index
transfer performance.
TODO: maybe we could speed up performance by unsing multiple transmission threads in
parallel instead of only a single one.
*) gzip encoded post requests
it is now configureable if a gzip encoded post request should be send on
intex transfer/distribution
*) storage Peer (very experimentell and not optimized yet)
Now it's possible to send the result of the yacy indexer thread to a remote peer
istead of storing the indexed words locally.
This could be done by setting the property "storagePeerHash" in the yacy config file
- Please note that if the index transfer fails, the index ist stored locally.
- TODO: currently this index transfer is done by the indexer thread.
To seedup the indexer
a) this transmission should be done in parallel and
b) multiple chunks should be bundled and transfered together
*) general performance improvements
- better memory cleanup after http request processing has finished
- replacing some string concatenations with stringBuffers
- replacing BufferedInputStreams with serverByteBuffer
- replacing vectors with arraylists wherever possible
- replacing hashtables with hashmaps wherever possible
This was done because function calls to verctor or hashtable functions
take 3 time longer than calls to functions of arraylists or hashmaps.
TODO: we should take a look on the class serverObject which is inherited from hashmap
Do we realy need a synchronization for this class?
TODO: replace arraylists with linkedLists if random access to the list elements is not needed
*) Robots Parser supports if-modified-since downloads now
If the downloaded robots.txt file is older than 7 days the robots parser tries to
download the robots.txt with the if-modified-since header to avoid unnecessary downloads
if the file was not changed. Additionally the ETag header is used to detect changes.
*) Crawler: better handling of unsupported mimeTypes + FileExtension
*) Bugfix: plasmaWordIndexEntity was not closed correctly in
- query.java
- plasmaswitchboard.java
*) function minimizeUrlDB added to yacy.java
this function tests the current urlHashDB for unused urls
ATTENTION: please don't use this function at the moment because
it causes the wordIndexDB to flush all words into the
word directory!

- more debugging output: storageTime for indexed document is logged now
- saving memory in plasmaParserDocument.java, plasmaWordIndexEntryContainer.java (not a big deal)

*) Replacing PDFBox 0.7.1 lib with newer version 0.7.2
*) Refactoring of classes httpd/httpc/httpHeaders to
make many methods for httpHeader/Requestline parsing
reusable for new icap implementation
*) adding chunked input stream support
- needed by new icap implementation
- needed by future httpc HTTP/1.1 support
*) httpd.java
- moving all connection property contants to class httpHeader
- moving readHeader function to class httpHeader
- moving parseQuery function to class httpHeader
- moving handleTransparentProxy function to class httpHeader
*) httpHeader.java
- adding new fuction to parse the http response line
- adding new function to converte http headers to a string that
can be send to the client
- adding a function that generates a proper url using all parsed
connection properties
*) ICAP Support
- yacy now supports handling of icap response modification requests
- this feature can be used by other icap enabled proxies to contact
yacy as icap server, and to handover the downloaded content to yacy.logging
for indexing
- functionality was successfully tested with squid 2.5Stable 10 + icap patch
- further icap services e.g. URL filtering based on yacy's blacklists are possible
*) plasmaSwitchboard.java
- htcache entries that are still needed for indexing are now properly registered
as in use after system restart
- extended logging: log message now shows parsing and indexing time for each sb. entry
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@757 6c8d7289-2bf4-0310-a012-ef5d649a1542
into the sb-queue anymore if the mimeType or fileExtension is not supported
by the installed parsers.
- Advantage: Avoiding unnecessary enqueueing and dequeueing from queue
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@664 6c8d7289-2bf4-0310-a012-ef5d649a1542
- harmonizing proxy exception handling
- adding malformed URL + blacklist check for http head method
- adding malformed URL check to http post method
- chunked encoding is now not used anymore for http post if clients
are http/0.9 or http/1.0 clients (same behaviour as already implemented for get)
- now an exception will be thrown on internal httpc errors to force an error output
to the client or a connection close. This should help to fix the "binary data in browser window" bug
*) plasmaSwitchboard.java
- fixing the following Bug
E 2005/09/03 18:02:42 PLASMA Could not index URL http://mis04.de/FAIL/snot.php: null
java.lang.NullPointerException

This bug could occure if the cached responseHeader is null
- getting the mimeType now from the parsed document instead of the responseHeader because the
mimeType could have been changed during content parsing (e.g. because of the mimetypeParser)
