Not using the JDK URLDecoder.decode() function, as it strips '+'
characters when they occur after '?' (both characters having regular
expression semantics when used in blacklist path patterns)
Normalize blacklist path patterns using percent-encoding, at pattern
edition in web interface and at loading from configuration files.
Fixes issue #237
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.
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.
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 ).
Consequently to the report in mantis 776
(http://mantis.tokeek.de/view.php?id=776).
Running the perfs test with different control parameters seems to reveal
that the YaCy's RowHandleMap used in the balancer depthCache is finally
more efficient than for example the ConcurrentHashMap from JDK 8.
When a crawl is started, a new field to exclude content from scraping is
available. The field can be identified with the class name of div tags.
All text contained in such a div tag where the configured class name(s)
match are not indexed, while the remaining page is indexed.
Upgraded to InetAccessHandler.
Added InetPathAccessHandler extension to InetAccessHandler to maintain
path patterns capability previously available in IPAccessHandler but
lost in InetAccessHandler.
Filtering on IPv6 addresses is now supported.
Support for deprecated pattern formats such as "192.168." and
"192.168.1.1/path" has been removed, but startup automated migration
should convert such patterns eventually present in serverClient.
Required to properly run on systems with default locale set to Turkish
language, as with this locale the 'i' character has different upper and
lower case flavors than with other locales.
For any relevant URL parts : host name, URL scheme, session ids or
technical parts (see https://url.spec.whatwg.org/#url-writing and
https://tools.ietf.org/html/rfc3986 for current standard references).
Remaining locale sensitive conversion used for detection of URL word
components in urlComps() makes sense but using detected language would
be preferable than using the default system locale.
Required for people using Turkish language as their default system
locale, as with this locale the 'i' character has different upper and
lower case flavors than with other locales.
Using current IANA reference list at
https://www.iana.org/domains/root/db
The generated URL hashes on these domains stay the same but performance
is greatly improved as a DNS resolve request is required on URL hash
computation when the TLD part of the host name is unknown.
Hash computation mean time measured on 1541 sample URLs (one on each
TLD) and a computer with a DSL connection : about 230ms before change,
then only 20ms.
The modified tests were successfull when run manually from an IDE such
as Eclipse, but failed occasionnally when run with maven as part of the
overall test suite.
The target image format (jpeg) doesn't support transparency, so the
Html2ImageTest produced unusable black images when ran on a linux
machine having imagemagick package installed.
