hold a date for each URL to record when a url was first seen. This is
then used to overwrite the modification date for urls upon recrawl in
case that the first-seen date is before the latest document date. This
behaviour is necessary due to the common behaviour of content management
systems which attach always the current date to all documents. Using the
firstSeen database it is possible to approximate a real first document
creation date in case that the crawler starts frequently for the same
domain. As a result the search results ordered by date have a much
better quality and the usage of YaCy as search agent for latest news has
a better quality.
*) will try other ports if YaCy standard ports are not available
*) distinguish between internal and external port (not sure if this
works 100%)
Still to add: propery in config to enter own external port (in case of
manually configured NAT)
removed preferred IPv4 in start options and added a new field IP6 in
peer seeds which will contain one or more IPv6 addresses. Now every peer
has one or more IP addresses assigned, even several IPv6 addresses are
possible. The peer-ping process must check all given and possible IP
addresses for a backping and return the one IP which was successful when
pinging the peer. The ping-ing peer must be able to recognize which of
the given IPs are available for outside access of the peer and store
this accordingly. If only one IPv6 address is available and no IPv4,
then the IPv6 is stored in the old IP field of the seed DNA.
Many methods in Seed.java are now marked as @deprecated because they had
been used for a single IP only. There is still a large construction site
left in YaCy now where all these deprecated methods must be replaced
with new method calls. The 'extra'-IPs, used by cluster assignment had
been removed since that can be replaced with IPv6 usage in p2p clusters.
All clusters must now use IPv6 if they want an intranet-routing.
hour. The table can be shown with
http://localhost:8090/Tables_p.html?table=stats
The entries have the following meaning:
aM: activeLastMonth
aW: activeLastWeek
aD: activeLastDay
aH: activeLastHour
cC: countConnected (Active Senior)
cD: countDisconnected (Passive Senior)
cP: countPotential (Junior)
cR: count of the RWI entries
cI: size of the index (number of documents)
The entry keys are abbreviated to reduce the space in the table as the
name is written again for every row.
This is the beginning of a 'yacystats' micro-alternative als built-in
function in YaCy. Graphics may follow after some time if enough test
data is available.
- default mySeed.ip to hostip in SeedDB.initMySeed() if Intranetmode
this allows to become senior status in intranet hosted search network with view peers,
otherwise peer would stay junior because of default init with loopback ip as public (dna) ip.
'cloud' was a bad idea. Changed also the accumulation process for peer
targets so that every dht chunk is not assigned the set of redundant
targets but they are assigned to redundant targets individually. This
enhances the granularity of the target accumulation and should enhance
the efficiency of the process. Finally the dht protocol client was
enriched with the ability to remove the 'accept remote index' flag from
peers or remove peers completely if they do not answer at all.
was optional and another alternative metadata store was available. Since
that store is now removed, Solr is always available (internally or
externally)
in peer hash hashing. This should not change anything if java casts long
to int by masking with 0xFFFFFFFFL but you never know. The important
thing is, that the hashCode() should not return numbers that have the
same order as the hash code order because hashing of seeds is used to
remove the order in some places.
