Normalize blacklist path patterns using percent-encoding, at pattern
edition in web interface and at loading from configuration files.
Fixes issue #237
To make seed upload (in /Settings_p.html?page=seed page) with SCP easier
when the user specify a remote target directory path.
See report by @vikulin in issue #227
- support of "%h" and "%t" pattern components
- more proper initialization of file handler when the data folder is not
the default one, notably to prevent a non blocking but ugly error stack
trace reported by the log manager at startup with that kind of setup
Previously, if YaCy log folder was for example at
`/home/user/yacy/DATA/LOG`, because of improper truncation of log path,
an unnecessary directory creation was atempted at `/home/us`.
- Removed calls to no more existing clearResources functions (on PDFont
class and its children) since upgrade to pdfbox 2.n.n
- Removed hacky usage of protected internal ClassLoader function. This
removes the warnings displayed when running with JDK9 or JDK10 :
[java] WARNING: Illegal reflective access by
net.yacy.document.parser.pdfParser$ResourceCleaner (file:<path>) to
method java.lang.ClassLoader.findLoadedClass(java.lang.String)
[java] WARNING: Please consider reporting this to the maintainers
of net.yacy.document.parser.pdfParser$ResourceCleaner
[java] WARNING: Use --illegal-access=warn to enable warnings of

Crawling thousands of pdf documents from various sources after
modifications applied, revealed no new memory leak related to pdfbox
(measurements done with JVisualVM).
As reported by @vikulin in issue #187, crawling websites using a raw
IPv6 address as host name in their URL failed when running on Microsoft
Windows platforms (FAT32 or NTFS filesystems) when YaCy crawler created
the crawl queue folder, as the ':' character which is part of an IPV6
address is forbidden on these filesystems.
The status of the library in the DictionaryLoader_p.html page now also
advertises the user that an upgrade can be applied when an older dump is
already loaded.
Upgrade applied as suggested by Niklas Andrus @fapth_gitlab on Gitter
chat.
Relative URLs to CSS stylesheets were not properly rendered when using
the Solr html response writer and the "/solr/collection1/select" entry
point instead of "/solr/select".
Was useless as done in an already synchronized block, and the lock
object was assigned a new value in that same block, and nowhere else a
lock is requested on that same object.
When using the 'From Link-List of URL' as a crawl start, with lists in
the order of one or more thousands of links, the failreason_s Solr field
maximum size (32kb) was exceeded by the string representation of the URL
must-match filter when a crawl URL was rejected because not matching.
SimpleDateFormat must not be used by concurrent threads without
synchronization for parsing or formating dates as it is not thread-safe
(internally holds a calendar instance that is not synchronized).
Prefer now DateTimeFormatter when possible as it is thread-safe without
concurrent access performance bottleneck (does not internally use
synchronization locks).

This makes possbile to set up much more advanced document crawl filters,
by filtering on one or more document indexed fields before inserting in
the index.
For a better control on the maximum simultaneous outgoing http
connections, as already done for any other http connections (crawls, rwi
search, p2p protocol) using the net.yacy.cora.protocol.http.HTTPClient
If not interested in displaying this on your search results and notably
on a peer with limited resources this can help saving some CPU and
outgoing network connections.
Consistently with the custom Solr http client used for https connections
to remote Solr peers or to YaCy external Solr storage.
This prevent remote Solr requests threads to wait for establishing a
connection to a remote peer longer than the configured timeout.
Initializing Thread names using the Thread constructor parameter is
faster as it already sets a thread name even if no customized one is
given, while an additional call to the Thread.setName() function
internally do synchronized access, eventually runs access check on the
security manager and performs a native call.
Profiling a running YaCy server revealed that the total processing time
spent on Thread.setName() for a typical p2p search was in the range of
seconds.
* less CPU usage using the Solr 'allowedTime' parameter
* increase chances to get some results even when a first operation step
goes in time out by letting some time for final snippets results
processing
Solr can provide partial results for example when a processing time
limit (specified with the parameter `timeAllowed`) is exceeded.
Before this fix, getting partial results from an embedded Solr index
resulted in a ClassCastException :
"org.apache.solr.common.SolrDocumentList cannot be cast to
org.apache.solr.response.ResultContext".
That was caused by concurrent modifications (with addHighlightField()
function) to the same SolrQuery instance when requesting Solr on remote
peers in p2p search.
By not generating MD5 hashes on all words of indexed texts, processing
time is reduced by 30 to 50% on indexed documents with more than 1Mbytes
of plain text.
if at least one of the image size fields is enabled in index (images_height_val,
images_width_val, images_pixel_val).
Previously all fields were required to be enabled (hint: default setting
is height + width enabled)
- properly handle IPv6 loopback address replacement
- replace loopback address or host only when accessing peer remotely
- replace loopback part with the peer hostname as requested rather than
with its seed public IP as this works better for Intranet mode and when
peer is behind a reverse proxy.
Otherwise once this operation is applied, the remote Solr(s) instances
are deconnected and the embedded Solr is connected even if disabled by
setting "core.service.fulltext".
Also use constants for related default setting values.
- Use the EnhancedXMLResponseWriter only when requested output is "exml"
- Use the Standard Solr writers when possible, for example for json, xml
or javabin output formats
- Return an error when the requested format can not been rendered with
an external Solr server only
Important : this modification is necessary for peers using exclusively
an external Solr server to be reachable as robinson targets in p2p
search, as the binary format ("javabin") is the default Solr exchange
format for peers.
Before this, when a peer requested a remote one attached only to an
external Solr (no embedded one), it ended with "Invalid type" error, as
the remote peer answered with xml although binary format was requested.
This is necessary when you want to attach to a dedicated external Solr
server protected with basic http authentication and requested over https
but having only a self-signed certificate.
The current default boost function
(`recip(ms(NOW,last_modified),3.16e-11,1,1)`) for the Date ranking
profile is indeed working fine.
What can trigger the error `unexpected docvalues type NUMERIC for field
'last_modified'` is the previous default boost function (quite old now)
or any custom one using the Solr `ord` or `rord` functions on the
last_modified field.
Then the problem was that the migration code in the Switchboard supposed
to detect the old date boost function was incorrect (one trailing right
parenthesis in excess), so the deprecated function remained.
This fixes issue #169.
- Fixes issue #160 : handle properly syntax exceptions with a user
friendly message
- Fixes loss of information on multiple blacklist entries editions
- Fixes loss of entries when moving entries from one list to another
Previously, when clicking a selected facet in the search results page to
unselect it, all other eventually selected modifiers/facets were also
removed.
With the appropriate vocabulary settings in Vocabulary_p.html page, this
can produce Vocabulary search facets displaying item types referenced in
html documents by microdata annotation.
Tested notably, but not limited to, vocabulary classes/types defined by
Schema.org and Dublin Core.
This adds the possibility for the HTML parser to gather typed items URLs
annotated in HTML tags with itemscope and itemtype attributes (see
microdata specification https://www.w3.org/TR/microdata/ ), notably
Types from the schema.org vocabulary, but also Types/Classes from any
other vocabulary, such as the common ones listed in the RDFa core
context ( https://www.w3.org/2011/rdfa-context/rdfa-1.1.html ).
Recrawl default profile was previously effectively used for crawl
stacker acceptance check, but request entries were indeed still created
with the "snippetGlobalText" profile.
Associate cached content to the last redirection location, instead of
the first URL of a redirection(s) chain :
- for proper base URL processing in parsers (fixes mantis 636 -
http://mantis.tokeek.de/view.php?id=636)
- to prevent duplicated content in Solr index when recrawling a
redirected URL
- with only light constraint on known indexed documents load date, as it
can already been controlled by the selection query, and the goal of the
job is indeed to recrawl selected documents now
- using the iffresh cache strategy
check case insensitive.
As keywords are compared lower case, make sure user input keyword:Key
or keyword:key will be shown as active in facet entry key.
Thus allowing to choose at configuration or per search request, whether
extending or not results beyond strict content domain filter (image,
video, audio or application).
Related graphical controls to be added to user interface.
Required for proper operation when the default system locale is Turkish,
as dottless and dotted i characters have specific case conversion rules
in this language.
Introduced through the new configurable setting
network.unit.protocol.https.preferred, defaulting to false for now.
Let choose to prefer using https when available on remote peers to
perform YaCy protocol operations including notably hello or transferRWI.
Not yet implemented for every YaCy protocol operations.
