- the list of urls is entered in the expert crawl start in a textfield;
the one-line input field was replaced with a text box
- start urls can also be given in one single line where the urls are
separated by a '|'-character
- as an effect, the crawl profile cannot carry a single start url for
identificaton because it is possible to have more. Therefore the url was
removed from the crawl profile
- this affect all servlets which display a crawl profile: removed the
url field from all there servlets
- to work consistently with several start urls and the other crawl
starts which computed crawl start url lists from sitelists or sitemaps,
the crawl start servlet was restructured completely
- new rules for must-match patterns were created to make it possible
that site crawl starts also work with several crawl starts at once
- a solr field collection_sxt can be used to store a set of crawl tags
- when this field is activated, a crawl tag can be assigned when crawls
are started
- the content of the collection field can be comma-separated, all of
them are assigned to the documents when they are indexed as result of
such a crawl start
- a search result can be drilled down to a specific collection; this is
currently only available in the solr interface and also in the gsa
interface using the 'site' option
- this adds a mandatory field for gsa queries (the google api demands
that field all the time)
A limit was necessary because some web pages have such huge numbers of
links that it can easily cause a OOM just by the number of links.
The quesion if the number of 1000 links is sufficient or too weak must
be answered with the result of testing this feature.
the segments had been there to create a tenant-infrastructure but were
never be used since that was all much too complex. There will be a
replacement using a solr navigation using a segment field in the search
index.
0-values and no empty strings are written). This may save a lot of
memory (in ram and on disc) if excessive 0-values or empty strings
appear)
- do not allow default boolean values for checkboxes because that does
not make sense: browsers may omit the checkbox attribute name if the box
is not checked. A default value 'true' would not comply with the
semantic of the browsers response.
- add a checkbox in IndexFederated_p for the lazy initialization of solr
fields.
parser. This makes it possible that every type of document can be a
crawl start point, not only text documents or html documents. Testet
this with a pdf document.
these bookmarks will be used to get a source reference for the search in case of intranet or portal searches.

- many speed/performance hacks
- added solr charding and new charding web interface
- added option to switch off the yacy index when using solr
- added new fail-url categories which are used to make a distinction which fail-urls to be sent to solr
- refactoring/renaming of some method names to distinguish host/url hashes better
- a large number of bug/npe fixes
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7738 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added option to crawler to send error-URLs to solr
- changed solr scheme slightly (no multi-value fields where no multi values are)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7693 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7672 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7666 6c8d7289-2bf4-0310-a012-ef5d649a1542
1) if the file is changed for a re-crawl this is not reflected in the steering because it would take the previously uploaded crawl start file
2) browsers do not submit the full path of the selected file even if this path is shown in the input field because of security reasons. There is no work-around or hack to make the submission of the full path possible
- fixed deletion of crawl start point urls in crawl stack and balancer double-check
- fixed a problem with steering self-call (no resolving of localhost)
- added more logging for the crawler to supervise why crawl urls are not taken by the loader
- added a javascript onload-function to select domain restriction in all cases where a crawl is started from a file or from a url
- fixed the restrict-to-domain pattern computation, added a 'www.'-prefix and added this functionality also to a crawl start from file
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7574 6c8d7289-2bf4-0310-a012-ef5d649a1542
- some restructuring of the document counting and logging structures was necessary
- better abstraction of CrawlProfiles
- added deletion of logs to the index deletion option (if the index is deleted using the servlets) which is necessary to reset the domain counters for the page limitation
- more refactoring to get the LibraryProvider more clean
- some refactoring of the Condenser class
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7478 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added a new queue 'noload' which can be filled with urls where it is already known that the content cannot be loaded. This may be because there is no parser available or the file is too big
- the noload queue is emptied with the parser process which indexes the file names only
- the 'start from file' functionality now also reads from ftp crawler
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7368 6c8d7289-2bf4-0310-a012-ef5d649a1542
- when a site-crawl for ftp sites is now started, then a special directory-tree harvester gets the complete directory structure of a ftp server at once
- the harvester runs concurrently and feeds into the normal crawl queue
also in this:
- fixed the 'start from file' crawl function
- added a link detector for the html parser. The html parser can now also extract links that are not included in <a> tags.
- this causes that a crawl start is now also possible from clear text link files

- better crawl star for files paths and smb paths
- added time-out wrapper for dns resolving and reverse resolving to prevent blockings
- fixed intranet scanner result list check boxes
- prevented htcache usage in case of file and smb crawling (not necessary, documents are locally available)
- fixed rss feed loader
- fixes sitemap loader which had not been restricted to single files (crawl-depth must be zero)
- clearing of crawl result lists when a network switch was done
- higher maximum file size for crawler
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7214 6c8d7289-2bf4-0310-a012-ef5d649a1542
- nobody understand the auto-dom filter without a lenghtly introduction about the function of a crawler
- nobody ever used the auto-dom filter other than with a crawl depth of 1
- the auto-dom filter was buggy since the filter did not survive a restart and then a search index contained waste
- the function of the auto-dom filter was in fact to just load a link list from the given start url and then start separate crawls for all these urls restricted by their domain
- the new Site Link-List option shows the target urls in real-time during input of the start url (like the robots check) and gives a transparent feed-back what it does before it can be used
- the new option also fits into the easy site-crawl start menu

- the scheduler extends the option for re-crawl timing. Many people misunderstood the re-crawl timing feature because that was just a criteria for the url double-check and not a scheduler. Now the scheduler setting is combined with the re-crawl setting and people will have the choice between no re-crawl, re-crawl as was possible so far and a scheduled re-crawl. The 'classic' re-crawl time is set automatically when the scheduling function is selected
- removed the bookmark-based scheduler. This scheduler was not able to transport all attributes of a crawl start and did therefore not support special crawling starts i.e. for forums and wikis
- since the old scheduler was not aber to crawl special forums and wikis, the must-not-match filter was statically fixed to all bad pages for these special use cases. Since the new scheduler can handle these filters, it is possible to remove the default settings for the filters
- removed the busy thread that was used to trigger the bookmark-based scheduler
- removed the crontab for the bookmark-based scheduler
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7051 6c8d7289-2bf4-0310-a012-ef5d649a1542
Here a new concept called 'search heuristics' is introduced. A heuristic is a kind of 'shortcut' to good results in IT, here for good search results. In this case it will be used to get a very transparent way to compare what YaCy is able to produce as search result and what g**gle produces as search result. Here is what your can do now:
- add the phrase 'heuristic:scroogle' to your search query, like 'oil spill heuristic:scroogle' and then a call to scroogle is made to get anonymous search results from g**gle.
- these results are _not_ taken as meta-search results, but are used to instantly feed a crawling and indexing process. This happens very fast, here 20 results from scroogle are taken and loaded all simultanously, parsed and indexed immediately and from the results of the parsed content the search result is feeded, along to the normal p2p search
- when new results from that heuristic (more to come) get part of the search results, then it is verified if such results are redundant to existing (they had been part of the normal YaCy search result anyway) or if they had been completely new to YaCy.
- in the search results the new search results from heuristics are marked with a 'H ++' and search results from heuristics that had been already found by YaCy are marked with a 'H ='. That means:
- you can now see YaCy and Scroogle search results in one result page but you also see that you would not have 'missed' the g**gle results when you would only have used YaCy.
- to make it short: YaCy now subsumes g**gle results. If you use only YaCy, you miss nothing.
to come: a configuration page that let you configure the usage of heuristics and get this feature by default.

- a new news db will be created (news1024.db), the old one (news.db) can be deleted
- peers with too large news payload are not ignored any more (they may have been invisible because they had a too large news payload!)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6917 6c8d7289-2bf4-0310-a012-ef5d649a1542
- it is now possible to crawl the local file system with an intranet peer
- redesign of URL handling
- refactoring: created LGPLed package cora: 'content retrieval api' which may be used externally by other applications without yacy core elements because it has no dependencies to other parts of yacy
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6902 6c8d7289-2bf4-0310-a012-ef5d649a1542
- used that to display two layers on map: cities and search result locations
- added many marker grafics for the display of the markers on the map
- some refactoring of the yacy news code plus bugfixes for latest move from Tree to Table data structure
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6889 6c8d7289-2bf4-0310-a012-ef5d649a1542
- added crawling queue sizes to /api/status_p.xml, syntax same as in queues_p.html

pass value as byte[], not as String. This should cause that less
byte[] <-> String conversions are made during time-critical tasks.

will loose its leading role for the re-crawl funtion when the new api tables will work. To be prepared for a replacement
of such functions the bookmark class is re-organised.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6637 6c8d7289-2bf4-0310-a012-ef5d649a1542
all operations on YaCy in a database that should make it possible
1) to re-create a setting on fresh peers
2) to transmit a setting from one peer to another
3) to re-create crawl starts after a complete deletion of the index
This functionality will also support
4) scheduled re-crawls (new implementation)
To implement this, a new database structure has been crated that stores maps into blob heaps. to encode maps the b-encoding technique was used (this is the same encoding that torrent files use)
- added a b-encoder
- enhanced the b-decoder
- added a b-encoded map heap data structure
- added a table organisation based on b-encoded heaps
- added a servlet to maintain such tables (see Tables_p.html)
- integrated the servlet into the Advanced Settings menu
- added an api recording based on the new tables

this was done because that servlet may be used for wget/cronjob
triggered crawl starts and it appears to be confusing that the
name of the crawl start servlet looks like a pure monitoring tool.
