tomFlowee c71ebb9bee Avoid reporting incorrect updates 2021-11-26 18:10:31 +01:00
tomFlowee 3a9863dbe3 Simplify the backup sync feature. 
The bloom filter includes all the unspent outputs, so we can just
use the latest one if we want to get any transactions the first
peer omitted.

tomFlowee 9a65a2f9c9 Remove empty and sometimes hanging DNS 2021-11-19 14:16:41 +01:00
tomFlowee 1b5ae89d31 [Refactor] rename FastTransaction.{h|cpp} -> Tx.* 2021-11-02 11:05:14 +01:00
tomFlowee d79ab0a301 Special case peers that are behind 
A peer that is behind is marked as "on a different chain", which is
ultimately correct, but the response to punish or ban them is too much.
We could very well reconnect later when the situation is resolved.

So, detect when a peer is simply behind and respond by disconnecting
without punishment.

tomFlowee 3841257505 Fix possible deadlock. 
The new iteration avoids having the blockchain mutex locked when it
calls up to the connection manager (which locks its own mutex).

tomFlowee a7c8f02c09 Face the reality of low number of testnet nodes. 2021-10-31 15:14:34 +01:00
tomFlowee 701698d6e1 Fix merkleblock download as bloom filters change. 
In HD wallets we get an issue where not-yet-generated keys are needed in
the merkle-block request and we notice this as a chunk of blocks is
being downloaded.
This is solved with some extra code.

Also avoid re-uploading the bloom filter during initial sync.
 2021-10-27 19:14:09 +02:00
tomFlowee c5e845b11b Be more generous with asking for headers. 
On connect, we should ask for a HEADERS overview from the remote peer,
even if we aren't fully at the tip yet.

Also remove some old lookup no longer used.

tomFlowee bdbde16e28 Make CleanPeers not ban good nodes 2021-10-27 19:14:09 +02:00
tomFlowee 1af7fea053 Fix too-fast-banning bug 
Sometimes a node would not be online for a while and we'd incorrectly
ban them for a long time when we just need to mark them as not-
reachable-right-now.

tomFlowee 6692a0a11a Follow API change in NWM. 
Setting the ringbuffers to not-so-tiny values
 2021-08-05 23:03:19 +02:00
tomFlowee d73763977c Avoid calls to listeners while we have a lock. 
This is a library class, lets be nice to users of our class and
avoid deadlocks.
 2021-07-31 18:25:24 +02:00
tomFlowee 77bd1ac74f Improve the SPV sync action. 
This re-thinks the way we assign new peers and massively speeds up the
finding of enough peer for our wallets.

tomFlowee d1fa3fa4a9 [P2P] Allow static loading of blockheaders 
This adds a unit test for the Blockchain class in the p2p lib and this
introduces the functionality to have a blockchain pre-shipped with an
app.
 2021-05-27 19:08:46 +02:00

tomFlowee 1f2f7c36d2 Port the boost container to the std one. 
The unordered_map is now available in stl, and said to be better,
so lets slowly switch over
 2021-02-03 16:31:46 +01:00
tomFlowee 1003ad716b Fixlets in log output consistency 2021-02-03 14:41:51 +01:00
tomFlowee 5d6d09e4d6 Assign segments only to good peers 
Instead of assigning a privacy segment at connect, wait until we have
determined if this peer is on the same chain as us before we allocate a
peer slot.

This also helps us limit the amount of peers we send our bloom filter to.
 2021-02-03 14:41:51 +01:00
tomFlowee 447a2e12e6 Add new action 
When a peer never sends headers we now ban it after a timeout based on
the idea that we don't even know if this peer is on the same chain as we
are.

Increase the score of an IP that is part of a feed.

tomFlowee c5fca38956 Check basedir or throw 
This makes the download manager fail fast, with appropriate logging, on
misconfiguration.

This removes some unused includes from common headers and dead code
from some C++ files.

TomZ 2b7ae939cf Simplify the syncchain action. 2020-11-13 21:03:56 +01:00
TomZ 301a4ca3ee Fix properly following the chain-tip 
This is done in several steps:

1. Separate my height from the remote peer heights.
Instead of assuming we have one height, recognize that a peer may
not be at the tip at the same time we are. We monitor headers/invs
to update the 'peerHeight' variable.

2. Ask for merkle blocks from a peer to the maximum height of that
peer (but not later than what we validated to be true).
This avoids us asking past the remotes tip which they didn't like.

3. Redo the SyncSPVAction to use all this and make it much more
reliable in finding peers to download from and getting all the
changes as fast as possible.
