f856edecb6 fix proxy redirect (http status 302) response
fixes http://mantis.tokeek.de/view.php?id=517

The url given in bug report uses a gzip input stream which causes the HTTPClient.writeto() throw an IOException due to incomplete input stream. This in turn prevents the 302 reponse to the client browser. 
By limiting to serve target content just on httpstatus=200 will proxy the header reponse and client browsers redirect settings can be honored.

eb78388a98 changed prefer strategy for http unique in such a way that http is
preferred over https. While this is a bad idea from the standpoint of
security it is more common applicable for environments where http and
https mix and for some domains https is not available. Then the
double-check is possible even if no postprocessing is performed.

8c3e5b7b6d added experimental pdf splitting which enables YaCy to split pdfs during
parsing into individual pages and add them all using different URLs.
These constructed urls are generated from the source url with an
appended page=<pagenumber> attribute to the url get/post properties.
This will distinguish the different page entries. The search result list
will then replace the post parameter with a url anchor # mark which
causes that the original url is presented in the search result. These
URLs can be opened directly on the correct page using pdf.js which is
now built-in into firefox. That means: if you find a search hit on page
5 and click on the search result, firefox will open the pdf viewer and
shows page 5.

d14114697c the miss cache does not seem to work, it sometimes contains urlhashes
from documents which actually are inside the index. This can be
reproduced using the crawl result table at 
http://localhost:8090/CrawlResults.html?process=5
The cache is temporary disabled to remove the bad behaviour, however a
later reactivation of that feater may be possible.

5516819354 preventing the use of no-cache and expires in case that images are
generated dynamically which will stay static in the future. This applies
mainly to the search result favicon in front of search hits. These icons
will now be generated once, but then caches in the browser. There is
also a YaCy-internal cache for these icons which had prevented the
re-generation of the icons in YaCy, but this cache is now superfluous
since the browser should not call the servlet ViewImage again.

65125439fe added query modifier 'on'. This makes it possible to search for date
occurrences within the (web) page documents (not the document
last-modified!). This works only if the solr field dates_in_content_sxt
is enabled. A search request may then have the form "term on:<date>",
like
gift on:24.12.2014
gift on:2014/12/24
* on:2014/12/31
For the date format you may use any kind of human-readable date
representation(!yes!) - the on:<date> parser tries to identify language
and also knows event names, like:
bunny on:eastern
.. as long as the date term has no spaces inside (use a dot). Further
enhancement will be made to accept also strings encapsulated with
quotes.

9971e197e0 Added a transaction interface to the snapshots: all documents in the
snapshots can now be processed with transactions using commit and
rollback commands. Furthermore, a large number of monitoring methods had
been added to check the success of transactions.

The transactions for snapshots have two main components: a rss search
API to get information about latest/oldest entries and a commit/rollback
API to move entries away from the rss results. This is done by usage of
two storage locations for the snapshots, INVENTORY and ARCHIVE. New
snapshots are placed to INVENTORY, commited snapshots move to ARCHIVE,
rollback snapshots move to INVENTORY again.

Normal Workflow:
Beside all these options below, usually it is sufficient to process data
like this:
- call
http://localhost:8090/api/snapshot.rss?state=INVENTORY&order=LATESTFIRST
- process the rss result and use the <guid> value as <urlhash> (see next
command)
- for each processed result call
http://localhost:8090/api/snapshot.json?command=commit&urlhash=<urlhash>
- then you can call the rss feed again and the commited urls are omited
from the next set of items.

These are the commands to control this:
The rss feed:
http://localhost:8090/api/snapshot.rss?state=INVENTORY&order=LATESTFIRST
http://localhost:8090/api/snapshot.rss?state=INVENTORY&order=OLDESTFIRST
http://localhost:8090/api/snapshot.rss?state=INVENTORY&order=ANY
http://localhost:8090/api/snapshot.rss?state=ARCHIVE&order=LATESTFIRST
http://localhost:8090/api/snapshot.rss?state=ARCHIVE&order=OLDESTFIRST
http://localhost:8090/api/snapshot.rss?state=ARCHIVE&order=LATESTFIRST

The feed will return a <urlhash> in the <guid> - field of the rss. This
must be used for commit/rollback:

Commit/Rollback:
http://localhost:8090/api/snapshot.json?command=commit&urlhash=<urlhash>
http://localhost:8090/api/snapshot.json?command=rollback&urlhash=<urlhash>
The json will return a property list containing the property "result"
with possible values "success" or "fail", according of the result. If an
"fail" occurs, please look into the log for further info.

Monitoring:
http://localhost:8090/api/snapshot.json?command=status
This shows the total number of entries in the INVENTORY and the ARCHIVE 
http://localhost:8090/api/snapshot.json?command=list
This will result a list of all hosts which have snapshots and the number
of entries for the hosts. Counts for INVENTORY and ARCHIVE are listed in
the porperties for "count.INVENTORY" and "count.ARCHIVE"
http://localhost:8090/api/snapshot.json?command=list&depth=2
The list can be restricted to such which have a specific depth. The list
contains then the same host names, but the count values change because
only documents at that specific crawl depth are listed
http://localhost:8090/api/snapshot.json?command=list&host=yacy.net.80
This lists all urlhashes for the given host, not only an accumulated
list of the number of entries
http://localhost:8090/api/snapshot.json?command=list&host=yacy.net.80&depth=0
This restricts the list of urlhashes for that host for the given depth
http://localhost:8090/api/snapshot.json?command=list&state=INVENTORY
http://localhost:8090/api/snapshot.json?command=list&state=ARCHIVE
This selects either the INVENTORY or ARCHIVE for all list commands,
default is ALL which means that from both snapshot directories the host
information is collected and combined. You can use the state option for
all the commands as listed above

Detailed Information:
http://localhost:8090/api/snapshot.json?command=metadata&urlhash=upiFJ7Fh1hyQ
This collects metadata information for the given urlhash. This can also
be restricted with state=INVENTORY and state=ARCHIVE to test if the
document is either in one of these snapshot directories. If an urlhash
is not found, an empty result is returned. If an entry was found and the
state was not restricted, then the result contains a state property
containing the name of the location where the document is, either
INVENTORY or ARCHIVE.

Hint:
If a very large number of documents is inside of INVENTORY, then it
could be better to call the rss feed with
http://localhost:8090/api/snapshot.rss?state=INVENTORY&order=ANY
because that is very efficient.

bbf0ac40c3 add the actual DateDetection class... (missed in latest commit) 2014-12-14 13:43:30 +01:00
Michael Peter Christen
66b5a56976 Added and integrated new date detection class which can identify date
notions within the fulltext of a document. This class attempts to
identify also dates given abbreviated or with missing year or described
with names for special days, like 'Halloween'. In case that a date has
no year given, the current year and following years are considered.

This process is therefore able to identify a large set of dates to a
document, either because there are several dates given in the document
or the date is ambiguous. Four new Solr fields are used to store the
parsing result:

dates_in_content_sxt:
if date expressions can be found in the content, these dates are listed
here in order of the appearances

dates_in_content_count_i:
the number of entries in dates_in_content_sxt

date_in_content_min_dt:
if dates_in_content_sxt is filled, this contains the oldest date from
the list of available dates

#date_in_content_max_dt:
if dates_in_content_sxt is filled, this contains the youngest date from
the list of available dates, that may also be possibly in the future

These fields are deactiviated by default because the evaluation of
regular expressions to detect the date is yet too CPU intensive. Maybe
future enhancements will cause that this is switched on by default.

The purpose of these fields is the creation of calendar-like search
facets, to be implemented next.
