warc = Web ARChive File Format.
Warc files with extension .warc or compressed warc.gz can be placed in the
DATA/surrogate/in and contained responses are imported to the index.
The used library is stream based so we can easily extend it later to use
and load warc's from the net.
A port value of -1 will disable this option.
If set to a value greater 0, YaCy listens on this of on the local loopback
address (127.0.0.1) for a shutdown or restart signal.
E.g. connect to http://localhost:8005/shutdown will stop the YaCy server.
http://localhost:8005/restart will restart it.
This option allows to stop YaCy locally independant from the web web
frontend (which might be configured for password protected remote access).
HTTP "Referer" header sent by the browser when using YaCy can now be
controlled either with the referrer meta tag as a global policy, or only
for search result links by adding the attribute rel="noreferrer".
To improve privacy with the less possible regressions, the default is
set as meta tag with value "origin-when-cross-origin" : internal YaCy
links behavior is not affected, but when visiting external websites
referrer url is not empty but stripped from query parameters and path.
Older browsers, Safari, MS IE and Edge do not support the referrer meta
tag, so the standard but less flexible noreferrer link type can also be
enabled as an alternative.
User-friendly settings page to be implemented.
low number of found documents - by adding additional end condition to
remove processed query with number of found docs <= process-chunck-size.
Noticed on query h4_txt:[* TO *], found 21, process 21, call of commit happend
but on next cycle same query again 21 docs found (while h4_txt was removed
from schema and committed inputdocuments).
Fix NPE on disabled local SolrIndex, occuring on search moving to the 2nd result page.
The debug purpose only setting to disabeling local SolrIndex (System Admin -> Debug Settings) should long term probably be removed from production code.
These fields are default enabled but with no doubt not strictly
mandatory with the current code base.
As reported by @reger24, splitting between essential mandatory and
optional fields is still to be improved to reflect the current YaCy
needs.
- Added a new method to check activation of mandatory fields on
Collection Configuration commit, consistently with checks previously
performed in Switchboard startup and with mandatory fields in the
default schema.
- Reorganized default schema and CollectionConfiguration enumeration :
moved no more mandatory fields in a specific section, and moved fields
enabled at startup to the mandatory section.
- Marked mandatory fields as required and with stronger font in the
IndexSchema_p.html page
sq=solr-querystring) to allow to filter simple text queries for processing,
remove toString for counter parameter
use more predefined constants in solrservlet
As reported by Palulukas in YaCy forum
(http://forum.yacy-websuche.de/viewtopic.php?f=18&t=5944&sid=dcef5b899ab4aa9b40e3a3d158c13aed#p33454)
the Index Export operation can fails, notably when the Solr index
contains one or more documents with empty (despite required)
"load_date_dt" field.
This fixes the export failure when the situation finally occurs, but
more should be done to harden verifications on minimum required fields.
to avoid repeat of tokenized url as description,

Add some javadoc, and not needed remove of omitted fields in postprocessing.
As discussed in PR #93 with @JeremyRand and @reger24 this new advanced
settings page includes:
- a new setting to control remote Solr responses encoding
- some existing debug settings which could not be set through the admin
user interface
index schema.
To assemble the original link url for out-/inboundlinks, icons and pictures
the *_protocol_sxt and *_urlstub_sxt is needed (due to the used data-reduced
storage methode). Auto-enable *_protocol_sxt if *_urlstub_sxt is enabled.
to be able to correctly assemble the original link url.
As mentioned in issue #103, control settings over YaCy disk usage
already existed but lacked a user-friendly way to set them.
I added it to the Performance_p.html administration page with a little
refactoring on the "Resource Observer" fieldset for improved
accessibility and HTML standards respect.
Also added the possibility to enable/disable the autoregulation fonction
from this page.
As reported by @tglman on issue #90, when searching images on the local
index only, pages next to the first were always empty. This was a
regression from commit c25e48e969.
This ensure consistent implementation of the url host hash generation
and easier usage finding in source code.
Also added a unit test for this function.
to use javax.servlet.http.Cookie parameters.
Depreciate now obsolete getHeaderCookies.
Adjust setting of MaxAge to spec if >= 0 otherwise keep default.
The main shutdown hook thread was not properly waiting for the main
thread termination which consequently could not properly close resources
and threads. After terminating a running YaCy peer this way (Ctrl+C in
console, or kill <pid> for example), you could see the still existing
DATA/yacy.running file.
Tested with :
- Debian Jessie openjdk 7 and 8 : regular shutdown, Ctrl+C, kill
command, system restart while yacy is running
- Windows 10 Oracle JDK 7 and 8 : non regression on regular shutdown
Applied rules :
- when the FTP URL denotes a file resource, stack it as any start URL :
eventually embedded links can be followed applying the usual depth rules
- when the FTP URL denotes a directory, list files under this directory
and stack them for crawl, and repeat the process on sub folders until
crawl depth is reached
to not already actives.
Dht results are now included in count this might over shoot on redundant
dht and solr, while the previous solr facet based was always low.
Fixes issue #90 for local queries only: Stealth mode, Portal mode or
Intranet mode.
For P2p mode, the issue would probably be difficult to solve with
reasonable performance. This is still to dig.
Also switched some InterreputedException catch log messages to warn
level as this is normal behavior when shutting down a peer.
Fixed yacysearch buttons navbar behavior to deal correctly with total
results count or offset over 1000. Also improved the buttons navbar to
be able to navigate over 10th page for local queries.
When a downloaded archive release is corrupted, empty, or can not be
opened for any reason, the update script must not be launched because it
erases the existing lib/*.jar libraries.
NullPointerException occurred when using and Identificator instance
which encountered and error in its constructor.
This error could be caused by a missing "langdetect" folder in the
current folder of the main process, or by simultaneous first calls to
the constructor, initializing concurrently the DetectorFactory.langlist.
Fixes the mantis 714 (http://mantis.tokeek.de/view.php?id=714)
When starting a crawl from a file containing thousands of links,
configuration setting "crawler.MaxActiveThreads" is effective to prevent
saturating the system with too many outgoing HTTP connections threads
launched by the crawler.
But robots.txt was not affected by this setting and was indefinitely
increasing the number of concurrently loading threads until most ot the
connections timed out.
To improve performance control, added a pool of threads for Robots.txt,
consistently used in its ensureExist() and massCrawlCheck() methods.
The Robots.txt threads pool max size can now be configured in the
/PerformanceQueus_p.html page, or with the new
"robots.txt.MaxActiveThreads" setting, initialized with the same default
value as the crawler.
It can take any Date field of the index and displays a list of year strings
in reverse order by the year (not the score/count).
To allow to define the index field to use, the fieldname (and title can be
appended to the navi's name "year" e.g. year:load_date_dt:LoadDate
It works also with dates_in_content_dts field (from the graphical date
navigator). Here the query parameter from: to: are used on selection as
Query modifier (for other dates currently no query parameter available, so
selection won't work to filter search results).
Not included in the UI Searchpage layout config so far (for experiment with
it manual change to conf needed).
