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.
to the client (not cookies only). This is used by some servlets to mainly
set "Access-Control-Allow-Origin" header. Added a contains check to be
sure no header set by Defaultservlet is overwritten.
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)
Reduced this vocabulary memory usage :
- by using only one map term2entries instead of two maps having the
same key set
- by generating the location object links on the fly using the
GeoLocation data instead of storing many duplicates of string prefix

As reported by @reger24, image and favicon viewing was broken with

to work directly with javax.servlet.http.Cookie (rename headerProps to
cookieStore as is only used for this).
(Re)implement set-cookie in DefaultServlet to make cookieAuthentication
work as designed.
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).
handler.
UrlProxyServlet splits url in parts to pass it on as parameter and
HeaderFramework constructs a url from param parts. This is obsolete if
already created url is used (makes HeaderFramework.getRequestURL obsolete
= removed)
to make all readily available information from the original ServletRequest
available to YaCy servlets (without converting data to internal structures).
The implementation of the common interface allows easier integration of
YaCy servlets with the servlet standard (e.g. shared login service with
the servlet container etc.)
When the peer is behind a reverse proxy providing SSL/TLS encryption,
the rendered absolute URLs should start with https when the user browser
requested https : added limited support to the X-Forwarded-Proto HTTP
header notably provided on Heroku platform.
Also added some unit tests.
When WikiCode inserted in a peer hosted Blog, Wiki, Messages or Profile
contains relative links (images or any content, hosted in DATA/HTDOCS),
it is more reliable to keep these links relative, especially when the
peer is behind any kind of reverse Proxy.
the navigator to include counts all matches (rwi+fulltext).
Fixing also unresolved_pattern in navigators title (of the counter)
The use of inurl: query modifier as filter has not been changed keeping
it as soft (unsharp) filter facet.
Upd StringNavigator to prevent empty string form multivalued solr fields,
removed date value conversion (better handled elsewhere, not need here).
Prepared the first basic navigators (for authors and collections) for the
list of SearchEvent.navigatorPlugins and adjusted servlet to use these.
- this allows to configure display order of these navigators (by ordering config string)
- eventually allows for additional and/or custom navigators using any
available index field without need for changing servlets
- the Collection navigation has been adjusted to exclude the internal,
default robot_* and dht collections from displaying
- rwi results are now also checked for navigatior by the refactored navi's
So far no config options were added to customize or add navigators (may
come later if route of upcoming modularization/plugin system is defined).
used for rwi ranking.
Main changes:
- introduce a posintext() to access the stored value. This reduces also mem alloc of position array for WordReferenceRow (index access)
- use the positions() array for joined references on multi-word queries if needed (otherwise allow positions() to be null
- adjust assignments and the min() max() and distance() calculation accordingly
during rwi search result processing worddistance calculation is effected
by concurrent update (normalization) of min/max ranking parameter for
wordpositions. On update of min/max the exception is raised in distance calc
and now catched.
This concurrent update and change of ranking results is needed for speed
but should be further checked for optimization
Applied strategy : when there is no restriction on domains or
sub-path(s), stack anchor links once discovered by the content scraper
instead of waiting the complete parsing of the file.
This makes it possible to handle a crawling start file with thousands of
links in a reasonable amount of time.
Performance limitation : even if the crawl start faster with a large
file, the content of the parsed file still is fully loaded in memory.
(again, description in http://mantis.tokeek.de/view.php?id=698)
as root cause was not seen, added just workaround reducing in favour over a
try catch (for easier followup).
Issue was the calculation in AbstractReference with positions.clear() call,
this made distance result always 0 (distance needs min 2 positions) and created concurrency issues.
+ unit test of changes
refactor to using long in URIMetadataNode too (and related call parameters)
As remote rwi score's are not used (since v1.83) skip reading float-score ,
but keep in toString() for communication with older versions.
- correct WordReferenceVars.toRowEntry posintext parameter
to set expected min posintext (the difference is on multi-word queries,
while positions are ordered by search word order).
- modified posofphrase/posinphrase join operation
- to set min posofphrase
- and keep posinphrase if not same posofphrase (was set to 0, no differentiation during ranking)
+ fix compiler msg (missing type declaration)
to make sure current dates are recognized (was fixed to 2014 - 2016)
+ adjust holiday date parser from pattern.match to pattern.find to deal with leading and trailing text
+ moved relative date recognition (morgen, tomorrow) to parseline (used by query parser only), as not working and problematic for indexing
+ add test case for parseline (used by query parser)
Shutdown was hanging in CrawlQueues.close() at
this.workerQueue.put(POISON_REQUEST) when config value
crawler.MaxActiveThreads was greater than 200.
Revealed by "Collision" Threads dumps in mantis 689
(http://mantis.tokeek.de/view.php?id=689#c1312)
Fixed consistency between this.worker.length and this.workerQueue
capacity, and made the process more reliable using non-blocking offer()
function.
First fix for mantis 689 (http://mantis.tokeek.de/view.php?id=689).
On Debian Linux, with a headless jre and no open browser,
browser.openBrowserClassic() was called and waited forever the browser
process end (p.waitFor()). YaCy shutdown was therefore not working until
the browser was closed.
Also modified browser opening command for Unix platform to open the
default the browser (with xdg-open util) instead of Firefox.
xdg-open also has the advantage to be asynchronous (not blocking).
file.separator to compute equal hashes (by normalizing path for computation)
+ expand test case for to check mixed java / windows file url notation
like e.g. file:///c:/test/file.html vs. file:///c:\test/file.html
- relates partially to http://mantis.tokeek.de/view.php?id=692
Even after network switch, ErroCache was still holding a reference to
the previous Solr cores, thus becoming useless until next YaCy restart.
Initial error cache filling with recent errors from the index was also
missing after the swtich.
The embedded core holds a lock on the index and must be closed. Earlier commit
comment states that core should be closed with solr instance instead on close
of connector.
Adjusted the InstanceMirror.close() to take care of closing the embedded
instance to release the lock.
In 2 routines of fulltext this was already explicite implemented (disconnectLocalSolr).
Now this disconnect is part of the InstanceMirror.close().
This file is used by Bootstrap documentation website
(http://getbootstrap.com/) but is not part of the Bootstrap distribution
and has not be included in a Bootstrap based application.
Purpose of the test case is to be able to (controlled) analyse the rwi ranking for
multi word searches (with focus on posintext and word-distance ranking)
version numbers are expressed in a different way as we expect. That
could cause that YaCy does not run on systems which are appropriate but
we simply do not understand the version string.
including a small change, word posintext counting.
We remember/store 1st posintext. Previously following words got a handle (posintext)
excluding found. Now it just counts and assigns true posintext as handle (posintext)
This is needed and enables existing word position ranking for RWI.
The upcoming concurrency issue in word position min/max calculation were eliminated
by iterator.hasHext check before next() access.
- move the maxcount limit restriction completely to getTopicNavigator (as there not used in getTopics)
- let search servlet use getTopics by default (w/o RWI connected check, as of now, Topics are available w/o any additional index interaction)
+ changed the postRanking to add one score only if word appears more as one time.
+ getTopics() unused code block rem'd (save performace)-> routine needs rework !
htroot is a supposed to be a subfolder of appPath and not of dataPath,
as assumed in other places where htroot is loaded. This issue was not
visible when dataPath and appPath are equals.
Added Javadocs to refactored methods.
Added log warnings instead of silently failing some errors.
Only fill collection1hosts when required ( shallComputeCR true).
New or modified translation (via /Translator_p.html) can be shared/distributed
via the YaCy internal news service. Remote peers can see and vote on the
translation via the new http://localhost:8090/TransNews_p.html servlet.
A positive vote will add the received translation to the local translation
list and post a voting message to the news service.
(at this no processing of received votings is implemented)
+ fixed the msg service retention time check (NewsPool.automaticProcessP)
If language is set to "browser" the client/user browser language is used to choose from
available translation.
simply: one users browser speaks English -> YaCy responds in English, other users browser speaks French -> YaCy responds in French.
! To make a translation/language available you have to activate the language once !
(or manually use the utility class TranslateAll)
In ConfigBasic.html availabel translations are marked green on setting language=Browser
The client language is determined by http header Accept-Language (checked in DefaultServlet)
use directly HttpServletRequest. This is used to get the http protocol version
in HTTPDProxyHandler.fulfillRequestFromWeb() for error response to client.
- adjust YaCyProxyServlet and UrlProxyServlet accordingly
- use more http_version constants in headerframework and httpdeamon
- equalize servlets (3) use of HeaderFramework.CONNECTION_PROP_HOST to HeaderFramework.HOST
to also support handling of urls w/o corresponding file-extension.
For this refactor use of document.getParserObject() to alway return a Parser (for clean logic)
and define/move the scraperObject as local var of AbstractParser.
Adjust related calls to getParserObject (where actually a scraperObject is wanted).
Addionally skip appending url token to parsed text for dht metadata entries
(by default returned as result by rwi index).
- after last_exec_date is altered, next_exec_date should be recalculated
- makes the recalculation of next_exec in advance (without api call surely made) in Switchbard.schedulerJob() obsolete
Slightly modify next_exec calc. on missed event to now+schedule_time (from fix 10min)
fix for http://mantis.tokeek.de/view.php?id=677
The difference is on scheduling a large number of rss feeds and loading
is not finished before shutdown of YaCy. The change makes sure not already
loaded RSS will be loaded by the scheduler on next startup.
after restart, put hosthash in queue's filename (which is used as primary
key for crawl queue. Hint: initial hosthash from url and recalculated hosthash
from just hostname:port are not the same.
fixes http://mantis.tokeek.de/view.php?id=668 (partially)
(by using the resultcontainer.size instead of input docList.size)
skip waiting for write-search-result-to-local-index
(by removing the Thread.join - which will bring a small performance increase)
be translated. To avoid key="TEST" sourcetext="this is a myTESTcase for it"
translation of partial terms/words.
Add check of word boundary before and after sourcetext (incl. take care
of current praxis for key to be delimetered by > <
+ add test case
process 1. load default from locales/*.*
2. load and merge(overwrite) from DATA/LOCALE/*.* (can be partial translation as it is merged)
- include all entries from DATA/LOCAL to be edited in Translator servlet
and save just modifications (instead of full list) to DATA/LOCALE
This shall make it easy to share modifications.
This is the 1st rudimentary approach to support the translatio utilities.
It allows currently to edit untranslated text and save it in a local translation file
in the DATA/LOCALE directory.
+ refactor Translator (less static's) to leverage on class overrides and support garbage collection for this 1 time routine
+ adjust TranslatorXliff to check for local translations in DATA/LOCALE,
this includes storing manually downloaded translation files in DATA as well
(to keep default untouched)
+ on 1st call of Translator_p a master tanslation file is generated, checking
the supported languages for missing translation text (later this masterfile is planned to part of the distribution, to harmonize translation key text between the languages)
Outlook: the local modifications (possibly as translation fragments instead of complete file) to be shared with maintainer using xlif features.
- in intranet mode getip returns null causing a NPE
- adjust starturl (which was set to http://localip/repository) which is never the start url for the Mediawiki
+ correct javadoc for seed.getIP()
to split query into multiple parameter on line separator in input query.
e.g. split "crawldepth_i_0^10.0 \n crawldepth_i:1^5.0"
but allow "url_file_ext_s:jpg OR url_file_ext_s:png" to be unsplitted
