instead of loading the solr document, an index only for the last loading
time was created. This prevents that solr has to fetch from its index
while the index is created. Excessive re-loading of documents while
indexing has shown to produce deadlocks, so this should now be
prevented.
This is almost working with many workarounds:
- run rm lib/yacycore.jar
- run ./gradlew clean build bundleNative
- run ant clean all
- run again rm lib/yacycore.jar
- run ./fixMacBuild.sh
The build is then inside build/mac/YaCy.app
Right now this works so far but it does not have the correct release
number inside.
Target is to make this working for Windows releases and to embedd jre
entirely.
This can be seen as a fix for
https://github.com/yacy/yacy_search_server/issues/343
however, the export was not flawed, it is just the impression that
something is wrong, but the export size must be smaller than the index
size because the index also containers error documents.
Now an information line is presented that shows i.e.:
"The local index currently contains 181,319 documents, only 106,887
exportable with status code 200 - the remaining are error documents."
a main problem when crawling is long waiting time cuased by crawl-delay
values from robots.txt entries. that attribute is not supported by
google and interpreted by yandex and bing in different ways. In large
crawls there is always one host which blocks the whole crawl with
extreme large values. YaCy now still obeys crawl-delay but limits them
to 10 seconds.
Additionally the blocking logic when loading new robots.txt was analyzed
and a deadlock was removed. Furthermore the construction of new queue
lists was redesigned and it was ensured that always a large list of
different hosts for host-balancing is provided for the loader.
We will use the default value for now on.
This is much better for resource economy and fits better into a
container/docker/kubernetes strategy.
Furthermore, a small memory footprint is essential for the usage on
small devices like RaspberryPi.
you can i.e. do:
export YACY_PORT=8092 && ./startYACY.sh
Just append "YACY_" to uppercase version of environment variables and
replace all "." with "_".
protocol completely
If you set now an empty password, then the http server will not ask to
authentify. This is required for environment where we attach an outside
authentification service like keycloak or similar using authentication
in an ingress proxy.
This change is part of the approach to run YaCy inside of a kubernetes
cluster where we do not want individual authentication of peers and want
to apply a ingress authentication.
variables
To use that feature, set an environment variable with prefix "yacy." and
suffix identical to the yacy configuration attribute name.
Additionaly we implemented a way to set a peer name using the setting
"network.unit.agent". This can therefore now be used to set a peer name
with the java call parameter
-Dyacy.network.unit.agent=anonymous
The purpose for this feature is the ability to set peer names in
mass-deployed kubernetes clusters to the same name to prevent that we
are flooding peer name statistics with auto-deployment-generated names.
Added also an example for one of the existing APIs. The problem is the
comma separator between objects which must not be there for the last
entry in a sequence. The new syntax adds the separator symbol
automatically.
These classes had been my own creative work.
Just the copyright line had been appeared possibly due to a bad
copy-paste activity, unaware that the line is a non-free addition.
For finer control over which parsed documents can trigger an addition of
their links to the crawl stack, complementary to the existing crawl
depth parameter.
When unauthenticated (or with insufficient rights) client is blocked
either because blacklisted or excessive request rate, render an error
message and a relevant HTTP status for API requests, instead of an empty
response that appears broken.
Acces rate limitations to this search mode by unauthenticated users are
set low by default to prevent unwanted server overload but can be
customized through the SearchAccessRate_p.html configuration page
Fixes#291
For better support of the search page usage with JavaScript disabled.
Reduces also the number of initial refreshes of the paginations links.
When JavaScript is enabled, pagination links are still regularly
refreshed until all the search feeds are terminated on server side.
Non regressions tested on the following platforms :
Linux Debian Stretch :
- Firefox 60.5.1esr
- Chromium 72.0.3626.96
Windows 10 :
- Firefox 65.0.1
- Chrome 72.0.3626.109
- Edge 25.10586.672.0
- IE 11.1540.10586.0
Mac OS :
- Safari 11.0
Previously search navigators/facets elements were sorted only by counts.
Now from the ConfigSearchPage_p.html admin page, sort direction
(ascending/descending) and type (on counts or labels) can be customized
independently for each navigator.
- set the chunksize to 100 to meet the max of the embedded solr
- re-enable sorting (the case where we switched it of should be away)
- enable recrawling on remote-solr
On some conditions (especially when reaching timeout), concurrent Solr
query tasks used by the /HostBrowser.html and /api/linkstructure.json
never terminated, thus leaking resources, as reported by @Vort in issue
#246
