d73c84f9a0 Allow initial buffer size definition in TransformWriter, and use available() method to set it in htmlParser. In this situation a ByteArrayInputStream is used so the available() method gives a good size estimation and avoid the buffer needing to be continually grown 2011-12-01 11:20:13 +00:00

49e5ca579f added new configuration property "crawler.embedLinksAsDocuments". If this is switched on (this is default now), the all embedded image, audio and video links from all parsed documents are added to the search index as individual document. This will increase the search index size dramatically but will also enable us to create a much faster image, audio and video search. If the flag is switched on, the index entries are also stored to a solr index, if this is also enabled.

610b01e1c3 - added a 'add every media object linked in a html document as a new document' to the html parser. This causes that all image, app, video or audio file that is linked in a html file is added as document. In fact that means that parsing a single html document may cause that a number of documents is inserted into the search index.
- some refactoring for mime type discovery

0c1b29f3c9 - applied many small performance hacks
- added a memory limitation in the zip parser and the pdf parser
- added a search throttling: if there are too many search queries are still to be computed, then new requests are not accepted for some time. if after a one second still no space is there to perform another search, the search terminates with no results. this case should only happen in case of DoS-like situations and in case of strong load on a peer like if it is integrated in metager.
- added a search cache deletion process that removes search requests in case that throttling happens

4bea3f9714 hack to reduce resource contention caused by massive UTF8 decodings which use java.nio resources:
used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

b77b8cac0c - enhanced html parser: recognized much more details in the content
- added more properties to solr index
- refactoring
- more constants in switchboard
- fix for some NPEs
- recognition of more images
- removed synchronization in HandleMap (obviously not necessary?)
- added a nolocal configuration to remove excessive dns lookup (works only on allip - default off). Indexes produced with this setting are all flagged with 'local' and are (on purpose) not usable for freeworld because they will be rejected as beeing local.

- added deletion of solr index in IndexControlRWIs
- added asynchronous adding of large url lists (happens when crawls are startet with file)
- fixed npe in Image display
- replaced language warning with fine logging
- added a domain name cache in Domains that helps to speed up the isLocal property (less DNS lookups)
- added a new storage class for this new cache: KeyList. The domain key list is stored in DATA/WORK/globalhosts.list
- added concurrent solr updates and chunked transfers (50 documents until a commit is done) for high-speed feeding (> 40000 ppm)
- fixed a bug in content scraper that chopped off large parts of crawl lists (using crawl start from file)

958ff4778e enhanced location search:
search is now done using verify=false (instead of verify=cacheonly) which will cause that much more targets can be found.
This showed a bug where no location information was used from the metadata (and other metadata information) if cache=false is requested. The bug was fixed.

Added also location parsing from wikimedia dumps. A wikipedia dump can now also be a source for a location search.
Fixed many smaller bugs in connection with location search.
