Current SVN should be compilable again.

Hi everyone,

A short message to let you know that we're nearing release time. The current
version (0.96.5) will expire on April 1st.

There has been numerous changes in SVN in the last two weeks, and I would
appreciate if you could all download the latest SVN version (at least r16089)
and let me know whether you experience problems with it.  Make sure to compile
with -O0 and -g, so that any core dump can be examined easily.

If you haven't tried out the enabling of the DHT, you can do so by typing:

        $ echo set enable_dht TRUE | gtk-gnutella --shell

on the shell with a running gkt-gnutella.  You can't undo that by setting
it to FALSE via the same way: you have to stop GTKG and edit your
~/.gtk-gnutella/config_gnet to reset the property to FALSE before re-launching.

DHT testing for leaf nodes is especially needed, to see whether bandwidth
requirements are compatible with leaf node mode.  You can enable the DHT
whether you are firewalled or not, but obviously you will be able to store
data for others only if you are not firewalled.

What needs most exercising currently is the download logic. Try to download
as much as possible, from firewalled servents, and possibly many files from
the same host.

Thanks for you help in testing!

Raphael

Quoting Alex <alex@...> from ml.softs.gtk-gnutella.devel:
:Could you please explain what DHT is with respect to gtkg? I'm only

:distributed hash tracker for decentralised trackers (IIRC).

Sure.

DHT stands for Distributed Hash Table.

In Gnutella, the DHT is used to store alt-locs (keyed by SHA-1) and
push-proxies (keyed by the GUID of the firewalled servent).  This allows
one to resolve source-less magnets.

As of today, there are only two vendors supporting the DHT: LimeWire and
gtk-gnutella.

The current implementation in GTKG is not complete though, in that GTKG
can only join the DHT and query it, but it does not publish information
yet.  Another limitation of the current implementation is that you need
to fully join the DHT structure to query it, whereas LimeWire has a degraded
implementation for nodes with too little bandwidth.

Due to LimeWire's poor choice of timeout constants, there is a fairly high
bandwidth price to pay to use the DHT.

The forthcoming 0.96.6 release of GTKG will not enable the DHT by default,
due to the fact that the implementation is still incomplete.  However,
all the features that have been implemented are fully functional:

* THe DHT implementation is following the LimeWire specifications regarding
  message structure, table architecture and protocols (Kademlia is the
  underlying DHT architecture and design).

* The DHT auto-bootstraps on the network, thanks to the relatively dense
  LimeWire network..

* The DHT is capable of storing data locally, if you are not firewalled,
  and naturally providing this data back to the nodes who ask for it.

* The DHT code can look for ALOC (alt-locs), to find other sources
  sharing a given file, and PROX (push-proxies) to be able to locate
  current push-proxies for a firewalled servent, considerably raising the
  chance that you can download from a firewalled (LimeWire) servent.

By default data stored in your node is kept in memory, but by setting
the property "dht_storage_in_memory" to FALSE, data will be kept on disk.
The reason this is not done by default is that the current implementation
is not handling disk-full conditions and GTKG is likely to crash if the disk
where ~/.gtk-gnutella lies becomes full.

This has been fixed.
Another important bug was just fixed in r16095.

All: please update from SVN and test this new version.

For the record: gtk-gnutella won't crash any longer under the same circumstances.
However, whether there's a bug in gtk-gnutella, the kernel or whether it's
perfectly legitimate that you're seeing inbound UDP packets from 0.0.0.0,
I don't know.
