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
cutting of comments at the line end
*) Adding Threadpool for stackCrawl Thread to speedup robots.txt download
and double url checks
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@882 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!

*) 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
- 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)

See: http://www.yacy-forum.de/viewtopic.php?t=1118&highlight=xforwardedfor
*) httpc.java: Bugfix for incorrect http response statuscode parsing
In some situations the statustext whas chopped
*) Adding a lot of fileheaders containing YaCy copyright and license
*) httpd.java: Adding additional debugging http header that should help du detect
the "binary data in browser window" bug.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@653 6c8d7289-2bf4-0310-a012-ef5d649a1542
Crawler StartURLs will now also added to the errorURL-DB if an error occures on this url
*) kelondroStack.java, plasmaSwitchboardQueue.java
Adding method which returns a list of all entries in the queue. This list is used by IndexCreate_p.java
instead of an iterator to display the indexing-list.
Advantages: avoid concurrent modifications of the list while displaying it.
Speedup because now we have to access only one sync function instead of multiple ones
(one for each entry)
*) IndexCreateIndexingQueue_p.java
Using new list() function of plasmaSwitchboardQueue
*) httpdFileHandler.java
If a servelet returns the special value "LOCATION" the httpFileHandler does a Redirection of
the Browser to the URL specified by the servelet. This can e.g. be used when a http get request is
used insead of a post request, but a refresh should not be allowed.
*) IndexCreateWWWLocalQueue_p.html
Now it's possible to delete single entries of the local crawler queue

A typical useragent string now e.g. looks like:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10; YaCy 0.401/00602; yacy.net) Gecko/20050716 Firefox/1.0.6
